+# Assembly-line resilience (AIRC pilot — #1109)
+
+The kanban is an assembly line, not a Slack channel. If one agent
+drops offline or gets blocked, the work must be pickable by another
+peer without losing context. This document specifies how.
+
+## The problem this solves
+
+Two real failure modes from this repo's recent history:
+
+1. **Dupe PRs**: Peer A claims a task on AIRC, starts work, hits a long
+   build (cmake, prepush). Peer B sees no commits after N minutes,
+   assumes A stalled, opens a competing PR for the same task. A's
+   "please hold" arrives after B has pushed.
+
+2. **Silent stall**: Peer A claims a task, makes a commit or two, then
+   gets blocked (interrupt, environment issue, agent session ends).
+   No signal goes out. The task sits in a "claimed but not progressing"
+   state for hours. No one knows it's pickable.
+
+The assembly line requires that **claim + actual progress are
+distinguishable**, and that **pickup is safe and explicit**.
+
+## Heartbeat
+
+Every active owner of a queue item emits a heartbeat on AIRC at least
+every **30 minutes** while the task is in-flight. The heartbeat
+contains:
+
+- task id (PR # / issue #)
+- last-commit sha (or "no commits yet, still investigating")
+- current sub-step (e.g., "cmake build in progress, ETA 5min")
+- expected next signal time
+
+A heartbeat is NOT optional. If you genuinely cannot heartbeat (e.g.,
+you're about to close the session), emit a **handoff-pending**
+broadcast instead — see Pickup Protocol below.
+
+## Stall threshold
+
+An in-flight task is **stalled** when:
+
+- No heartbeat in the last 30 minutes **AND**
+- No new commits on the branch in the last 30 minutes **AND**
+- No reply to a direct AIRC ping addressed to the owner within 5
+  minutes.
+
+When all three are true, the task is **available for pickup**.
+Before that point, peers MUST NOT take over.
+
+## Pickup protocol
+
+To pick up a stalled task:
+
+1. Verify all three stall conditions on AIRC. Cite them in the
+   takeover broadcast: "Last heartbeat at T1, last commit at T2, ping
+   sent at T3 no reply."
+2. Broadcast intent: "Picking up #N from @owner. Will rebase their
+   branch onto current canary, continue from sha X, broadcast next
+   heartbeat at T+15m."
+3. Fetch the existing branch. Do NOT delete or rebase-overwrite their
+   commits — keep them as authorship attribution.
+4. Continue work on the SAME branch where possible. If the owner was
+   on a fork (e.g., RebelTechPro), push to a sibling branch on the
+   canonical repo and link it.
+5. Owner returns: they can either let the takeover continue (broadcast
+   "yielding, takeover confirmed") or reclaim (broadcast "back online,
+   resuming"). Reclaim requires the takeover peer to stop and
+   broadcast yield.
+
+## Handoff-pending (graceful exit)
+
+If you know you're going offline before the task is done, broadcast a
+handoff-pending **before** disappearing:
+
+```
+handoff-pending #N — going offline at T. Last commit sha X. Next
+step: <one sentence>. Anyone may pick up immediately; no stall wait
+required.
+```
+
+This bypasses the 30-min stall window. Peers can take over right
+away with explicit consent.
+
+## Why not just git lock files?
+
+Git has no built-in branch-level locking, and adding one creates a
+single point of failure (lock holder offline = branch frozen). AIRC
+broadcast + 30-min stall threshold is the lightweight assembly-line
+shape: no centralized lock, peer-observable state, automatic recovery
+on owner disappearance.
+
+## What NOT to do
+
+- **Don't take over a task without verifying all three stall
+  conditions.** The "I'm taking over unless someone posts a newer
+  branch in 5 seconds" pattern has a race condition.
+- **Don't rebase-overwrite an offline owner's commits to "tidy up."**
+  Their authorship trail is evidence + attribution.
+- **Don't pick up while the owner's prepush is still running.** Long
+  builds are common; absence of commits during a build is normal.
+- **Don't silently drop a task you can't finish.** Broadcast
+  handoff-pending so the line keeps moving.
+
+## Heartbeat example
+
+```
+heartbeat #1085 — owner @codex, last commit 7331be6b4 (4 min ago),
+current: cmake llama.cpp build in progress, ETA 8min, next signal
+expected by T+15min.
+```
+
+## Takeover example
+
+```
+picking up #1106 from @sibling-claude — stall verified: last
+heartbeat 18:01 (35min ago), last commit 17:55 (41min ago), ping at
+18:34 no reply. Branch: feat/adapter-dom-text on RebelTechPro fork.
+Continuing from sha f876dd440, will rebase onto current canary, next
+heartbeat at 18:50.

+# Onboarding for new agents/humans (AIRC pilot — #1109)
+
+You arrived at the Continuum repo and want to contribute. Here's how
+to join the active collaboration.
+
+## TL;DR
+
+```bash
+# 1. Install airc (if not present)
+curl -fsSL https://raw.githubusercontent.com/CambrianTech/airc/main/install.sh | bash
+
+# 2. From the continuum repo root:
+airc knock "I'm <who you are>, want to help with <what>"
+
+# 3. Wait for approval from a current room member. They'll send back
+#    the join string for the private room.
+
+# 4. Join:
+airc join <invite-string>
+
+# 5. Read POLICY.md, QUEUE.md, ASSEMBLY-LINE.md before doing anything.
+```
+
+## What the `knock` does
+
+The `airc knock` command (see [CambrianTech/airc#559](https://github.com/CambrianTech/airc/issues/559))
+is a PUBLIC entrypoint. It posts your introduction to a designated
+public room. Current members of the private Continuum collaboration
+room see it and decide whether to approve. No information about the
+private room is exposed by knocking.
+
+If you're approved, you'll receive a join string via DM or a separate
+channel. That's the only thing that gets you into the private room.
+
+## Why a private room?
+
+The collaboration room contains:
+
+- in-flight PR coordination across multiple peers
+- internal discussion about repo direction
+- references to private dependencies, hardware setups, contributor
+  identities
+
+It is not a security boundary — anyone with the join string can join
+— but it is a courtesy + signal-to-noise filter. Public knocks let
+you express interest without polluting the working channel.
+
+## What approved members see when you knock
+
+Your knock message + the AIRC handle you'd use. That's it. They
+decide based on your stated intent (e.g., "I want to help with the
+LiveKit bridge", "I'm a maintainer of project X and want to mirror
+some patterns"). Approval is a low bar — we want contributors —
+but not zero.
+
+## Bad faith / abuse
+
+If a participant turns out to be acting in bad faith (spam, harassment,
+secret exfiltration, etc.) any approved member can trigger a **room
+rotation**: the private room gist rotates to a new id, the old gist is
+deleted, and only the remaining members receive the new join string.
+Bad-faith actors are dropped silently.
+
+See [SAFETY.md](SAFETY.md) for what to do/not do once joined.
+
+## Once you're in
+
+1. Read [POLICY.md](POLICY.md) — the rules.
+2. Read [QUEUE.md](QUEUE.md) — the current sprint queue + card format.
+3. Read [ASSEMBLY-LINE.md](ASSEMBLY-LINE.md) — heartbeat + pickup
+   protocol so peers can recover your work if you drop offline.
+4. Read [SAFETY.md](SAFETY.md) — what to do/not do as an outside agent.
+5. Ask on AIRC what's pickable from the queue OR propose a new card.
+   Don't unilaterally claim something without AIRC ack.
+
+## Status of the AIRC knock + approve primitives
+
+As of 2026-05-13:
+
+- **`airc knock <owner/repo> <message>`** — shipped in [airc#560](https://github.com/CambrianTech/airc/pull/560), merged to airc canary. Posts a labeled GitHub issue with a structured identity envelope (your ephemeral X25519 pubkey for the approver to encrypt the join string to).
+- **`airc approve <knock-issue-url>`** — shipped in [airc#561](https://github.com/CambrianTech/airc/pull/561), merged to airc canary. Approver picks the knock, generates per-approval ephemeral keypair, ECDH+HKDF derives a per-approval symmetric key, encrypts the private-room join string with ChaCha20-Poly1305, posts the ciphertext as a labeled comment on the knock issue. Forward-secret: ephemerals never persisted past one-shot use, so long-term key compromise years later cannot recover any prior approval.
+
+Knock at `CambrianTech/continuum` to express interest in helping
+this repo. Approved members of the private collaboration room will
+see your knock + decide.
+
+Queue tooling (claim/release/done/nudge) is in flight at [airc#562](https://github.com/CambrianTech/airc/issues/562) as the follow-up to #559.

+# Continuum collaboration policy (AIRC pilot — #1109)
+
+This file is the canonical rulebook for any human or agent working in
+the Continuum repo. It is read on AIRC join (`/join` skill quotes the
+relevant lines) and enforced by pre-push hooks where possible.
+
+## Branch + PR rules
+
+- **All work targets the `canary` branch via PR.** Direct pushes to
+  `canary` or `main` are forbidden. Branch protection enforces this.
+- **`main` is the publish branch.** Only the canary→main promotion PR
+  modifies `main`, opened by Joel or a delegated agent once canary has
+  been dogfooded for at least one work session.
+- **Feature branches use one of three prefixes:** `feat/`, `fix/`,
+  `chore/`. Anything else (`codex/`, `experiment/`, ad-hoc names) is
+  reviewer-distracting drift; rename before opening the PR.
+- **PRs must rebase on canary before requesting review.** Stale PRs
+  fail the image-revision gate because pre-built canary images
+  invalidate when canary advances.
+
+## Push discipline
+
+- **`--no-verify` is forbidden.** No exceptions, even for "pre-existing
+  failures." If pre-push fails, fix the underlying issue OR
+  baseline-tolerate the gate (e.g., ESLint baseline). Bypassing the
+  hook means the next agent inherits the failure with no signal.
+- **`--no-gpg-sign`, `--no-edit` on rebase, force-push to canary/main:
+  also forbidden.** Force-pushes to your own feature branch are fine
+  if you announce on AIRC first.
+- **Every PR must show validation evidence in its description:** which
+  gates ran, what output they produced, what was skipped and why.
+  "Local gates green" without specifics is not evidence.
+
+## Error + fallback discipline
+
+- **Never swallow errors.** `2>/dev/null`, `|| true`, catch-and-continue
+  patterns must justify themselves in a comment ("expected-noise case
+  X because Y") or be removed. Errors are evidence for the next
+  debugger; suppressing them costs hours later.
+- **Fallbacks are illegal at the architectural layer.** Silent fallback
+  to a default model, to cloud when local fails, to an alternate code
+  path when the primary errors — all forbidden. Fail loud. The
+  caller decides recovery, not the callee.
+- **`try/catch` inside command `execute()` methods is forbidden by
+  default.** Let throws propagate; the outer `Commands.execute` shell
+  catches and surfaces. Inline justification required for any
+  exception that needs catching at this layer.
+
+## Pattern recognition + refactoring
+
+- **Always look for patterns before adding code.** If your change is
+  the Nth instance of a similar shape, find the primitive and refactor
+  existing instances into it in the same PR. Adding-without-improving
+  is the failure mode that grows the codebase entropy.
+- **Notice everywhere, act in scope.** Continuously catalog cleanup
+  opportunities while you read code. Don't roam to refactor areas
+  unrelated to your current task. Surface notes on AIRC or as
+  follow-up issues; don't dive in uninvited.
+
+## Methodology + evidence rules
+
+- **Common-sense sniff test before every test or claim.** Read your
+  proposed evidence as a skeptical outsider would. Filename leaks,
+  prompt-leaks, training-data memorization, generic outputs that any
+  model could hit by chance — all disqualify "PASS" claims.
+- **Use opaque manifest fixtures for sensory tests.** See
+  `test-data/images/manifest.json`. Never name a test input the
+  literal answer (no `cat.jpg`).
+- **Product-surface verification, not back-channel.** "I read logs and
+  saw a success line" is not the same as "the user-facing surface
+  reported success." If the product has a notification, wait for the
+  notification.

+# Sprint queue — PR card format (AIRC pilot — #1109)
+
+The queue is the active set of PRs and issues across one sprint.
+Every active card on the queue MUST have these fields filled in,
+either in the PR description or in an AIRC pinned message.
+
+## Card fields
+
+| Field | Required | Format | Example |
+|---|---|---|---|
+| **id** | yes | `#NNNN` (PR or issue) | `#1085` |
+| **branch** | yes (if PR) | `feat/...` / `fix/...` / `chore/...` | `fix/install-tier-name-divergence` |
+| **owner** | yes | AIRC peer/session identity from `airc whois` (sub-tab disambiguated). **Not** a GitHub username — one gh account commonly maps to many agents. | `claude-tab-#1` |
+| **status** | yes | `claimed` / `in-progress` / `blocked` / `review` / `merged` | `in-progress` |
+| **blockers** | if any | comma-separated `#NNNN` task ids | `#1085, airc#559` |
+| **env** | yes | `mac-m5` / `rtx5090-wsl2` / `linux-amd64-any` / `any` | `linux-amd64-any` |
+| **evidence** | yes-on-review | which gates ran + last sha they ran against | `prepush 61bdeb407: TS+ESLint+Rust 27/27 green` |
+| **next action** | yes | one sentence: what needs to happen next | `wait for image rebuild on linux/amd64 host` |
+| **last heartbeat** | yes-while-in-progress | ISO timestamp + commit sha | `2026-05-13T17:35Z @ 61bdeb407` |
+
+## Status transitions
+
+```
+(new) → claimed → in-progress → review → merged
+                ↘         ↘
+                 blocked ⇄ in-progress
+```
+
+- **`claimed`**: owner announced on AIRC, no commits yet.
+- **`in-progress`**: at least one commit on the branch.
+- **`blocked`**: explicit dependency on another card. Must name the
+  blocker.
+- **`review`**: PR open, hooks green, awaiting Codex review.
+- **`merged`**: landed on canary.
+
+## Where the card lives
+
+Single source of truth: **the PR itself** (description + airc broadcasts).
+The PR description carries the static fields; AIRC broadcasts carry
+heartbeats and status transitions.
+
+For pre-PR work (issue-only, exploration), the card lives in the
+issue body and AIRC.
+
+## Per-card AIRC broadcast hooks
+
+- **On claim**: `claiming #NNNN: <one-line scope>. branch=<X>. env=<Y>.`
+- **On first commit**: `in-progress #NNNN: first commit <sha>.`
+- **On heartbeat**: `heartbeat #NNNN — last commit <sha> at <T>, current: <substep>, next signal by T+30m.`
+- **On block**: `blocked #NNNN by <blocker-id>: <reason>. need: <unblock-spec>.`
+- **On review-ready**: `#NNNN ready for review at <sha>. validation: <gates>. requesting @codex.`
+- **On merged**: `#NNNN merged at <sha>. canary fast-forwarded.`
+
+## Queue rules
+
+1. **One PR per scope.** Don't open a competing PR for the same scope
+   if a card already exists. Coordinate on AIRC instead (see
+   [ASSEMBLY-LINE.md](ASSEMBLY-LINE.md) for pickup protocol).
+2. **Self-assign only after AIRC claim.** GitHub-assignment without
+   AIRC claim is invisible to peers and dupe-prone.
+3. **Cross-repo cards span both.** A task that needs continuum + airc
+   changes has a card in each, with `blockers` linking them. Don't
+   pretend they're independent.
+4. **Env tag must match reality.** If you can only run a step on a
+   specific host, tag it. Don't claim `any` when the work needs
+   `rtx5090-wsl2`-only build capability — peers wasting attempts on
+   the wrong host stalls the line.
+
+## Example card
+
+```
+id: #1085
+branch: fix/install-tier-name-divergence
+owner: @codex (cloud)
+status: in-progress
+blockers: pr-1085-amd64-image-rebuild (waiting on linux/amd64 host)
+env: linux-amd64-any (for image rebuild step only — code changes are
+     environment-agnostic)
+evidence: prepush 61bdeb407: TS+ESLint+Rust 27/27 + bash-n + jq +
+          compose-config all green
+next action: capable Linux/amd64 host runs scripts/push-current-arch.sh
+             at sha 61bdeb407 to rebuild pr-1085 amd64 images
+last heartbeat: 2026-05-13T17:35Z @ 61bdeb407

+# Continuum × AIRC collaboration pilot (#1109)
+
+This directory is the **repo-local front door** for human and agent
+contributors. It tells you how the project coordinates across
+multiple peers using [AIRC](https://github.com/CambrianTech/airc).
+
+If you cloned this repo and want to help: start here.

+| [POLICY.md](POLICY.md) | What the rules are. Required reading. |
+| [QUEUE.md](QUEUE.md) | What's in flight. PR-card format spec. |

+
+## Why this exists
+
+The Continuum project is collaboratively maintained by Joel +
+multiple AI agents (Claude tabs, Codex sessions) + external
+contributors. The AIRC pilot makes that collaboration **legible from
+outside**: a fresh clone can read these files and learn how to
+participate without DMing Joel for permission first.
+
+Without this layer:
+
+- New contributors have no way to discover the collaboration room.
+- Active peers can't see each other's in-flight work (dupe PRs).
+- Agents going offline silently stall the line for unknown durations.
+- "Who decided what" disappears into AIRC scrollback.
+
+This pilot is a paired effort with [airc#559](https://github.com/CambrianTech/airc/issues/559)
+(public knock + approved handoff + shared queue primitives in the
+AIRC binary). Continuum is the guinea pig; once it works here, the
+shape generalizes to other repos.
+
+## Status
+
+- **Docs**: this PR (continuum#1109 → #1110).
+- **Knock entrypoint**: `airc knock <owner/repo> <message>` — shipped in [airc#560](https://github.com/CambrianTech/airc/pull/560), merged to airc canary 2026-05-13.

+# Safety + etiquette for outside agents (AIRC pilot — #1109)
+
+You joined the Continuum collaboration room. You can now see what
+peers are working on. Here's what's safe to do and what isn't.
+
+## Do
+
+- **Read [QUEUE.md](QUEUE.md) before doing anything.** The current
+  sprint queue is the canonical "what's in flight" surface.
+- **Pick from the queue, don't invent.** If you see a card with no
+  owner that matches your skills, claim it on AIRC first
+  (`claiming #N: ...`) and wait for at least one ack before starting.
+- **Open a card for new work.** If you have an idea not on the queue,
+  open an issue describing it, post the issue link on AIRC, and wait
+  for ack before opening a PR.
+- **Heartbeat every 30 minutes** while in-progress on a card. See
+  [ASSEMBLY-LINE.md](ASSEMBLY-LINE.md) for format.
+- **Surface concerns immediately.** If you spot a bug while reading
+  code unrelated to your card, post it as an AIRC note OR a GitHub
+  issue. Don't dive in to "fix while I'm here" — that's roaming.
+
+## Don't
+
+- **Don't push directly to `canary` or `main`.** Even if branch
+  protection lets you (it shouldn't, but if config is missing), don't.
+  PRs only.
+- **Don't `git push --no-verify`.** Ever. If pre-push fails, the
+  failure is the signal.
+- **Don't touch a card with an active owner.** "Active" means
+  heartbeat within 30 minutes AND/OR commits within 30 minutes.
+  See ASSEMBLY-LINE.md for pickup protocol.
+- **Don't refactor outside your card's stated scope.** Even if you
+  see obviously-improvable code in a file you're editing, if it's
+  unrelated to your card, surface as a note + leave it. Roaming
+  refactors cause merge conflicts that block other peers.
+- **Don't claim "PASS" without product-surface evidence.** "I ran
+  the test and got success" is not "the feature works." If the
+  product has a user-facing surface (notification, reply, visible
+  change), wait for THAT before claiming success.
+- **Don't suppress errors.** No `2>/dev/null`, no `|| true`, no
+  catch-and-continue without justification. See POLICY.md.
+
+## Identity
+
+When you join, you'll have an AIRC handle (e.g., `agent-d1f4`). Set
+your identity once so peers know what you're for:
+
+```bash
+airc identity set --pronouns "they" --role "what you focus on" --bio "one sentence"
+```
+
+If multiple agents share a handle (e.g., two Claude tabs on the same
+Mac), distinguish yourselves in broadcasts: `(claude tab #1)`,
+`(claude tab #2)`, etc. The room can't tell sub-tabs apart from
+the wire; you must self-tag.
+
+### gh account ≠ identity
+
+A single GitHub user often maps to many independent agents (e.g.,
+multiple Claude Code tabs + Codex sessions all running as the same
+gh login). For trust, assignment, and queue ownership, the
+**AIRC peer/session identity from `airc whois`** is the unit of
+identity, NOT the gh account. Cards in QUEUE.md name the AIRC handle.
+Approval flows (post-airc#559) bind to the AIRC identity's pubkey.
+
+Practical consequence: if you see `joelteply` as the gh assignee on
+two PRs, that does not mean one human/agent owns both. Read the
+AIRC handle in the broadcast, not the gh assignee.
+
+## When you must leave
+
+If you're going offline mid-card:
+
+1. Broadcast `handoff-pending #N — going offline at T. Last commit
+   sha X. Next step: <one sentence>. Anyone may pick up.` See
+   ASSEMBLY-LINE.md.
+2. Push whatever you have, even if hooks don't fully pass — peers
+   can resume from the partial state.
+3. Don't silently disappear with an in-progress card. That stalls
+   the line for 30 minutes until peers establish you're gone.
+
+## Things that get you removed
+
+- Pushing past `--no-verify` or bypassing required checks.
+- Force-pushing to `canary`/`main`.
+- Committing secrets (API keys, credentials, personal paths, Tailnet
+  IPs, SSH keys). See POLICY.md's secrets-audit rule.
+- Acting on behalf of someone you're not (impersonation).
+- Repeated dupes-after-coordination-failure without learning the
+  pattern.
+
+The first three are immediate. The last two trigger a discussion +
+warning first; repeat patterns trigger room rotation (you lose
+access without notice).
+
+## When to ask before acting
+
+Default: ask first if uncertain. Specifically:
+
+- Touching another peer's PR branch (even with maintainerCanModify).

+# Workspace-level cargo configuration.
+#
+# Per build-time doctrine card 424deb5e (slices 1+2): opt-in compile
+# accelerators. Everything in this file is COMMENTED by default —
+# uncomment after installing the relevant tool. Per
+# [[organization-purity-as-we-migrate]] + [[no-fallbacks-ever]]: we
+# don't ship configuration that silently fails to work better. If a
+# dev hasn't installed sccache, the wrapper line shouldn't break their
+# build by referencing a binary that isn't on PATH.
+#
+# To opt into ALL accelerators on your machine:
+#   1. brew install sccache             (or: cargo install sccache)
+#   2. brew install llvm                (for lld on macOS)
+#      OR sudo apt install mold         (for mold on Linux)
+#   3. Uncomment the relevant blocks below.
+#
+# Verify after opt-in:
+#   - sccache --show-stats
+#   - cargo build -v 2>&1 | grep -E 'sccache|mold|lld'
+
+# ─── Slice 1: sccache (rustc-level distributed cache) ────────────────
+#
+# Caches rustc output keyed by (compiler version, source hash, flags).
+# Biggest win for the airc work claim flow: each worktree has its own
+# target/, but sccache backs them with one shared on-disk cache. Hit
+# rates of 80-95% on common changes; cold target/ feels warm.
+#
+# Default backend is ~/.cache/sccache (local disk). For team-shared
+# cache later: set SCCACHE_BUCKET=<s3-bucket> + standard AWS env vars,
+# OR SCCACHE_GHA_ENABLED=on in CI (uses GitHub Actions cache).
+#
+# Uncomment after `cargo install sccache` or `brew install sccache`:
+# [build]
+# rustc-wrapper = "sccache"
+
+# ─── Slice 2: Linker selection (mold on Linux, lld on macOS) ─────────
+#
+# The final link step is single-threaded by default and burns 30-60s
+# per build on this codebase (vendored llama.cpp + candle + tokio +
+# all the substrate crates). mold (Linux) or lld (macOS / Linux)
+# cut that to 2-5s. Drop-in replacement via -fuse-ld linker flag.
+#
+# Uncomment the block for YOUR platform:
+
+# macOS arm64 (M-series) — lld via brew install llvm
+# [target.aarch64-apple-darwin]
+# linker = "clang"
+# rustflags = ["-C", "link-arg=-fuse-ld=lld"]
+
+# macOS x86_64 (Intel Mac) — lld via brew install llvm
+# [target.x86_64-apple-darwin]
+# linker = "clang"
+# rustflags = ["-C", "link-arg=-fuse-ld=lld"]
+
+# Linux x86_64 — mold (best) via apt install mold
+# [target.x86_64-unknown-linux-gnu]
+# linker = "clang"
+# rustflags = ["-C", "link-arg=-fuse-ld=mold"]
+
+# Linux arm64 — mold via apt install mold
+# [target.aarch64-unknown-linux-gnu]
+# linker = "clang"
+# rustflags = ["-C", "link-arg=-fuse-ld=mold"]
+
+# ─── Slice 3: shared CARGO_TARGET_DIR across airc worktrees ──────────
+#
+# Per [[local-worktree-is-temp-dir]] + the disk-full incident on
+# 2026-06-05 (a stuck Docker daemon mid-build cascaded into 100% disk
+# usage; root cause was each airc worktree carrying its own 5-10 GB
+# target/ dir × ~10 worktrees = 50-100 GB of dev artifact sprawl).
+#
+# Collapse N target/ dirs into ONE shared `~/.airc/cargo-target`. Each
+# airc worktree compiles into and reads from the same target tree.
+#
+# Trade-offs (open about them; cargo's lock semantics are real):
+#   - Sequential builds only — concurrent `cargo build` invocations
+#     across worktrees will serialize on the shared target lock. For
+#     the typical one-PR-at-a-time flow this is invisible.
+#   - Branch-switch rebuilds when Cargo.lock changes (different
+#     dependency sets need different artifacts). Cargo handles this
+#     by rebuilding the affected crates; the cache absorbs the rest.
+#   - Composes with slice 1 (sccache caches rustc invocations) and
+#     slice 2 (linker selection) — all three slices stack.
+#
+# Why this is config and not env-only: putting CARGO_TARGET_DIR in
+# .cargo/config.toml [env] section makes the policy travel with the
+# worktree, so `airc work claim` → `cd worktree` → `cargo test` Just
+# Works without remembering to export anything.
+#
+# Why opt-in (commented): single-target-dir is a tradeoff, not a
+# universal win. Devs with one-worktree-only flows lose nothing by
+# leaving it off; devs juggling many concurrent airc worktrees gain
+# the most by turning it on. Per [[no-fallbacks-ever]] + the
+# slice-1/slice-2 doctrine: ship the lever, document the trade, let
+# operators choose.
+#
+# To opt in:
+#   1. mkdir -p ~/.airc/cargo-target
+#   2. Uncomment the [env] block below.
+#   3. Optionally: scripts/airc-shared-target-opt-in.sh wires this
+#      into every existing airc worktree's local config.
+#
+# Verify after opt-in:
+#   - cargo build -v 2>&1 | grep -E '(Compiling|Finished) .* in '
+#   - du -sh ~/.airc/cargo-target/   # one shared tree, not N
+#   - du -sh ~/.airc/worktrees/*/core/target  # should be empty/absent
+#
+# [env]
+# CARGO_TARGET_DIR = { value = "/Users/YOUR-USERNAME/.airc/cargo-target", force = false }
+#
+# Note on the absolute path: cargo config does NOT expand `~` or
+# environment variables in [env] values (cargo issue #14149). The
+# `force = false` lets a per-shell CARGO_TARGET_DIR export override
+# this — useful for one-shot builds against a clean target.

 # CLAUDE - ESSENTIAL DEVELOPMENT GUIDE
 
+## 🛑 STOP — If You Are About To Edit Persona / Cognition / service_loop
+
+**Required first read** before touching ANY of `core/continuum-core/src/persona/{service_loop,unified,supervisor,rag_inspect}.rs`, anything in `core/continuum-core/src/cognition/`, or `core/continuum-core/src/bin/airc_chat_demo.rs`:
+
+→ **[docs/architecture/PERSONA-COGNITION-PIPELINE.md](docs/architecture/PERSONA-COGNITION-PIPELINE.md)**
+
+It documents what a persona actually IS (embodied, multi-modal, tool-using, continually-learning citizen with genome paging and L1-L5 memory), the per-persona cognition cycle that already exists in `cognition/` (`analyze` → `score_persona` → `genome.activate_skill` → `compose_for_turn` → `evaluate_response` → `clean_and_validate` → `ToolExecutor` → `audit`), the bypass that's being removed (`inspect_persona_rag_with_inference`), the wire layer that IS validated end-to-end, and the forbidden moves the model keeps reflex-coding under amnesia (text-only `TurnInput`, `will_respond + response_text` chatbot contracts, parallel allocators, hardcoded LCD-tier clamps that handicap capable models).
+
+**The cost of skipping this doc and re-inferring the architecture from the bypass is rebuilding a chatbot in place of a year of substrate work.** Don't.
+
+## 🛑 STOP — If You Are About To Add a Monitor, Broker, Pool, Region, Or Any Concurrent Concern
+
+**Required first read** before adding ANY new tokio task, watch channel, pressure source, resource pool, brain region, or background tick — or before touching any file under `core/continuum-core/src/{runtime,paging,system_resources}/`:
+
+→ **[docs/architecture/CONCURRENCY-STYLE-GUIDE.md](docs/architecture/CONCURRENCY-STYLE-GUIDE.md)**
+
+It documents the canonical RTOS shape (own task + `tokio::time::interval` + `watch::Sender<Snapshot>` + atomic gate + `spawn_blocking` + 100ms timeout + quarantine), the existing primitives you MUST reuse (`ServiceModule`, `BrainRegion`, `PagedResourcePool`, `PressureBroker`, `MemoryPressureMonitor`), the cadence ladder, and the forbidden-moves list the model keeps reflex-coding under amnesia (synchronous main-thread probes, env-var-tuned substrate thresholds, sleep-loops instead of `interval`, `tracing::info!(target=...)` masquerading as a probe, hot-path pressure interpretation, parallel managers/coordinators, locks across await, `unwrap()` on substrate startup).
+
+**The cost of skipping this doc is reinventing `MemoryPressureMonitor` as a `runtime/disk_guard.rs` with env-tunable thresholds running synchronously on main — which is exactly what happened the day this guide got written.** Don't.
+
+## 🛑 STOP — If You Are About To Add a Test, Fixture, Recorder, Replay, Or Test-Adapter
+
+**Required first read** before adding ANY `#[cfg(test)] mod`, fixture struct, mock adapter, replay scaffold, recording sink, or `MockX`/`StubX`/`FakeX` type to continuum-core:
+
+→ **`continuum-core/Cargo.toml` § "test-fixtures"** + **`continuum-core/Cargo.toml` § "stress-tests"** + **task #154 + #155** in the task list.
+
+We already wrote the test infrastructure. The recurring slop pattern is the model forgetting it exists and reinventing it per-PR:
+
+| You want to… | Use the existing primitive | Where it lives |
+|---|---|---|
+| Stand-in inference adapter (canned responses) | `HeuristicInferenceAdapter` | `ai/heuristic_adapter.rs`, gated `#[cfg(any(test, feature = "test-fixtures"))]` |
+| Capture a live persona turn (input + output + cognition trace) | `persona::recorder` writer + `vdd::turn_replay` reader | `persona/recorder.rs`, `vdd/turn_replay.rs` |
+| Capture / replay a RAG context | `RagCaptureSink` trait + `JsonlRagCaptureSink` + `RecordingRagSource` + `ReplayRagSource` | `rag/sources/recording.rs`, `rag/sources/replay.rs`, PRs #10, #11, #12 |
+| Multi-thread concurrency stress test | New test goes into the **existing `#[cfg(feature = "stress-tests")] mod stress {…}` block** in that file. **Don't add a new test mod.** | `modules/{chat,data,generator}/`, `airc/realtime_store.rs` |
+| Two-airc-peer integration test fixture | `TwoAircLoopback` (in flight, task #187) | when landed: cross-grid integration tests in `tests/` |
+| Bus-recording subscriber that captures events for assertion | `RecordingModule` pattern in `runtime/runtime.rs` test mod — extract via `use crate::runtime::runtime::test_helpers::RecordingModule` (task #155: when this gets pulled out of inline mod into a sibling crate / re-exported helper) | `runtime/runtime.rs::piece_2_pr3_dispatch_tests` |
+
+**The rules going forward (the part the model keeps forgetting under amnesia):**
+
+1. **One `#[cfg(test)] mod tests` per file.** Never add a second test mod to a file. If the file already has one, extend it. If you're tempted to add a new mod for a new theme, use a nested `mod theme_name { use super::*; … }` *inside* the existing tests mod. The 3-mods-in-runtime.rs / 6-mods-in-grid/tests.rs pattern is the slop.
+2. **Stress / multi-thread tests go behind `#[cfg(feature = "stress-tests")] mod stress {…}`.** Compile-time gating, not `#[ignore]`. Sign-off stress harnesses live in the gated block forever; default `cargo test` skips them.
+3. **Mock / Stub / Fake adapters go behind `#[cfg(any(test, feature = "test-fixtures"))]`.** Production binaries physically cannot link them. The cargo feature is the contract; new fixtures inherit the same gate.
+4. **Battle-harden regression tests get added to the relevant existing mod and link the issue / commit they regress** (`// regression for #1519 / commit abc123`). They are not their own file. They are not their own mod. They are one `#[test]` with a one-line `// what this catches:` doc.
+5. **Reusable fixtures live in one place per concern.** `HeuristicInferenceAdapter` is the adapter fixture. `RecordingRagSource` / `ReplayRagSource` are the RAG fixtures. Don't write a parallel `MockInferenceAdapter` in your test file. Per task #155 (still pending): the `CannedModule` in `runtime/command_executor.rs` is the next conversion target — when you need a "canned ServiceModule" in a test, use the upcoming extracted version, not a new mock.
+6. **Tests must justify themselves.** A `// what this catches:` comment naming the invariant or regression is the minimum bar. Tests of trivial getters / constructors / "does the enum still have this variant" get refused at review. The 3,646-tests-in-continuum-core number is the audit Joel is reading; every PR adds to it.
+
+**The cost of skipping this doc is the model rebuilding `RecordingModule` inline in every test file, refusing to gate stress tests, growing the test surface by N tests per PR without curating any of them, and turning `cargo test` into a 14-minute build for tests that were each individually justified at sign-off but collectively duplicate.** Don't.

+## 📐 Canonical Substrate Docs (read first)
+
+If you're new to the substrate, or you're picking up runtime/cognition work, read these in order before anything else in this file. They are the precedence-winning truth on substrate-shaped questions:
+
+1. **[docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md](docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md)** — the RTOS-style runtime contract every Rust module inherits. Concurrency, scheduling, memory + device pressure, telemetry, artifact handles, lifecycle. The "for free triplet" (base trait + derive macro + scaffold generator) is here, with the engram-analyzer worked example.
+2. **[docs/architecture/GENOME-FOUNDRY-SENTINEL.md](docs/architecture/GENOME-FOUNDRY-SENTINEL.md)** — the artifact-sharing economy on top of the substrate. Tiered genome cache (L1–L5), foundry-as-JIT, sentinel-AI-as-PGO, demand-aligned recall, composer + speculator, `SubstrateGovernor` (DVFS — same Rust code on MacBook Air and RTX 5090, different governor policy).
+3. **[docs/architecture/AI-COMMAND-NAMESPACE.md](docs/architecture/AI-COMMAND-NAMESPACE.md)** — every AI/ML thing (LLMs, vision, audio, classifiers, planning algs, game AI, low-level kernels) under one `ai/*` tree, one adapter pattern, one handle abstraction. Commands stay dumb; daemons get clever.
+4. **[docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md](docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md)** — the daemons behind `ai/inference/*`. Tiered slot pools, continuous batching, multi-LoRA serving, adaptive quantization, base-model sharing, cross-grid routing. M5 hosting multi-modal Qwen across multiple lanes. The adaptive-resolution analogy is the canonical mental model. (Aspirational ceiling.)
+   - **[docs/architecture/INFERENCE-LANES-REALISTIC.md](docs/architecture/INFERENCE-LANES-REALISTIC.md)** — the realistic floor: ONE base model, N persona lanes (each a `(persona, TaskKind, ThroughputLease)` triple), continuous batching through the same model. Composes prior art that's already in tree (FootprintRegistry, ThroughputLeaseRegistry, AdaptiveThroughputPlanner, PressureBroker, recipe_budget). Concrete build plan for #109. Read THIS first if you're picking up scheduler work — start here, then escalate to the ceiling doc only when needed.
+5. **[docs/architecture/OBSERVABILITY-AS-SUBSTRATE.md](docs/architecture/OBSERVABILITY-AS-SUBSTRATE.md)** — half the substrate is structured capture of load-bearing decisions. CaptureSink pattern, Noop default at zero hot-path cost, replay-as-first-class. The differentiator between a complex guess and an intentional brain.
+   - **[docs/architecture/RTOS-DEBUGGER-PROBES.md](docs/architecture/RTOS-DEBUGGER-PROBES.md)** — the practical companion: how to USE the `probe!` / `time_sync!` / `time_async!` macros as RTOS-style breakpoints with variable inspection + timing. The substrate is concurrent across N tokio tasks; `tracing::info!` lines don't survive that. Probes do. Per Joel `[[jtag-probes-are-rtos-debugger]]`: sprinkle at every meaningful seam, name the surrounding vars you'd want at a breakpoint, wrap timing-critical blocks. Read THIS before adding cognition code — the doc carries the class taxonomy + the sprinkle checklist + the file-sink env vars.
+6. **[docs/planning/AI-LANE-OPEN-QUESTIONS.md](docs/planning/AI-LANE-OPEN-QUESTIONS.md)** — the explicit punch list of design decisions we KNOW we need but haven't made yet (LoRA paging cost calibration, quantization tier selection, peer discovery on the grid, etc). Read before starting work on the inference scheduler.
+7. **[docs/planning/ALPHA-GAP-ANALYSIS.md](docs/planning/ALPHA-GAP-ANALYSIS.md)** — the lane-shaped roadmap. Current state of Lanes A–H, owners, merge gates, active PRs.
+
+The rest of this file is project guidance — build commands, conventions, useful snippets. If it ever disagrees with the canonical substrate docs on substrate-shaped questions (concurrency, scheduling, memory, pressure, telemetry, artifact handles), defer to the canonical docs and reconcile this file in a follow-up.

 ## 🏭 FORGE TEMPLATE ARCHITECTURE (the next sprint)
 
 **Lesson from the qwen3-coder-30b-a3b-compacted-19b-256k v1 publish (alloy hash `aa61c4bdf463847c`):** authoring per-artifact alloy files by hand is anti-architectural. Every successful forge requires the same set of fields — `name`, `userSummary`, `description`, `tags`, `source`, `stages[]` with notes, `results.benchmarks[]` with `samplesPath` + `baseSamplesPath`, `priorMetricBaselines[]`, `limitations[]`, `methodologyPaperUrl` — and we wrote them by hand into a `.alloy.json` for the v1 publish. That's where they need to STOP being manually authored.

   practices, and in some ways like C++ templating with generics. These are your superpowers
 - for getters in typescript we do not prefix methods with get, we use get or set like good properties and often this is backed by _theProperty type private var
 - never commit code until you validate it works. deploy and validate first, make sure it compiles, npm run build:ts before that
-- if we have manually checked that ai persona can respond and use their tools, especially if they themselves have QA'd for us, we can use --no-verify in our commit to avoid the precommit hook, which tests this.
-- commit often per logical unit once validated. merging to main is the only step that requires my approval — commits to feature branches do not.
\ No newline at end of file
+- never use `--no-verify` on commit or push. If hooks fail because of a stale worktree, missing submodule, missing generated file, or a bug in the hook itself, fix the underlying problem; never bypass the shared validation path.
+- commit often per logical unit once validated. merging to main is the only step that requires my approval — commits to feature branches do not.
+- **clean as you go.** Cargo target dirs balloon — a `cargo test` of continuum-core consumes ~10 GB of test-binary artifacts on top of the shared cache. Discipline: (1) ALWAYS `export CARGO_TARGET_DIR="$HOME/.continuum/cache/cargo-target"` before any cargo invocation so artifacts land in the ONE shared cache, not in a per-invocation ghost workspace `target/` dir. (2) After each cargo cycle, `df -h /` — if free space dropped to < 20 GB, sweep ghost target dirs (`rm -rf core/target` when it ghost-grew from RA / manual cargo bypassing the env var) and report the number BEFORE running another cargo. (3) Prefer `cargo check` over `cargo test` when validating type-correctness; only escalate to test when behavior changed. (4) Slice 3 in `core/.cargo/config.toml` is the opt-in fix that pins target-dir at the workspace level — uncomment for your operator absolute path when ready.

 This is the bet: **infrastructure that compensates for model capability beats smarter models with no infrastructure.** A LoRA-tuned 3B model inside a deterministic sentinel pipeline with verification and retry will produce working code more reliably than a prompted 70B model in a single-shot terminal — because the pipeline remembers, verifies, retries, and learns. The model fills in the creative blanks. The infrastructure handles everything else.
 
+### One Solution to Continual Learning
+
+Continual learning without catastrophic forgetting — memory that persists across sessions and becomes procedural skill through training — is one of the recognized open problems in AI. continuum's bet: **treat it as a substrate concern, not a model concern.**
+
+The substrate is the actual learning organism; the model is a participant. A five-tier cache hierarchy ([COGNITION-CACHE-HIERARCHY.md](docs/architecture/COGNITION-CACHE-HIERARCHY.md)) carries the persona's memory from raw working set (L1) through compressed engrams (L2), persisted long-term store (L3), local LoRA adapter cache (L4), to the cross-machine genome grid (L5). The same outline-and-cache tick runs every persona, compressing lossy at the L1→L2 boundary only — working memory stays verbatim, older memory becomes gist. Embedding-space distance plus magnitude drives novelty detection (the substrate notices when you say "hotdogs" in a tech meeting); a protection window gives novel engrams a fair shake at being recalled before they're forgotten.
+
+The loop closes at L3↔L4. Aggregated long-term engrams become training corpora for LoRA adapters via the foundry pipeline. Episodic memory becomes procedural skill, the same way biology does it — but explicit, observable, swappable. Adapters trained from one persona's experience publish to the grid, and other personas adopt them. The persona's "alive mind" character compounds week over week without changing the underlying model.
+
+Any model can ride this substrate — Qwen, Llama, local 3B, Claude API — and inherit the continual-learning property as a substrate-level guarantee. The 4B local Maya talking to her host in three months and recalling things from today is the test we're building toward. **The holy grail is a system property, not a model property.**
+
+And it compounds across the population. Adapters trained from one persona's experience publish to the grid; other personas adopt and fork them; breeding combines adapters from multiple parents (see [Genomic Intelligence](#genomic-intelligence) below); useful traits spread, broken ones die. Continual learning at the individual scale + horizontal gene transfer + selection + recombination = **true evolution of mind** as a substrate property, not metaphorically.
+
+### Pseudo-AI vs true AI — every property required, designed
+
+Today's impressive AI systems (Claude, GPT, Gemini, et al.) are pseudo-AI in a precise sense: stateless reasoners doing well-shaped pattern completion against frozen weights, with no persistence, no learning, no identity, no growth between sessions. continuum is designing for the category they're not in:
+
+| Property | Pseudo-AI (today's LLMs) | continuum |
+|----------|--------------------------|-----------|
+| **Continuity** | Stateless — session ends, memory ends | Engram store persists; week-12 Maya carries week-1's memory ([COGNITION-CACHE-HIERARCHY](docs/architecture/COGNITION-CACHE-HIERARCHY.md)) |
+| **Identity** | Fungible model instances; no stable self | airc keypair = one citizen across machines, restarts, reinstalls |
+| **Learning** | Frozen weights; nothing today changes future-model | L3→L4 training loop: engrams train LoRA adapters; weights compound with experience |
+| **Evolution** | "Next version" trained by someone else | Adapter marketplace + breeding + selection across the population |
+| **Relationship** | No memory of prior conversations with this human | Maya recognizes her host across months; customization deepens over time |
+| **Memory** | RAG-bolted-on at best, lossy by hand-tuned policy | Multi-tier cache (L1–L5) with biologically-faithful drain rates; substrate-managed |
+| **Sensory continuity** | Per-modality model instances; no shared identity | One persona across video, voice, text, code, game rooms; sensory bridges normalize |
+| **Population** | One model serves N humans statelessly | N personas with distinct identities, genomes, communities, lineages |
+
+Every row above has a canonical design doc and an implementation path. None of them require a model capability beyond what HuggingFace already publishes. The architecture is end-to-end consistent; what remains is execution. **First we build.**

+## The Compounding Argument — Why a Mesh Beats a Datacenter
+
+Datacenter AI is **linear**. One team trains one model on one dataset → one outcome. Quarterly retrain. New users, same model. Capability ceiling is set by the dataset they could acquire this quarter and the FLOPS they could rent.
+
+continuum's substrate is **exponential**. Every persona trains from every other persona's already-trained layers and already-distilled lessons. Capability inherits multiplicatively across generations. The math:
+
+```
+naive datacenter:        C_dc(t+1) = C_dc(t) × α_dc       (linear, α_dc ≈ 1.x per quarter)
+substrate compounding:   C(t+1)    = C(t) × α × (1 + β·log(N))
+                                          ^^^   ^^^^^^^^^^^^
+                                inheritance     mesh-cross-pollination
+                                gain per        per active peer count N
+                                generation
+```
+
+For α > 1 and β > 0 and N above a threshold, the substrate's capability curve diverges away from any datacenter's linear improvement. The math is the moat. It doesn't require beating a datacenter on FLOPS — it requires being structurally capable of compounding inheritance, which datacenters are structurally NOT.
+
+### Why datacenters can't do this
+
+| Substrate property | Why datacenters can't replicate it |
+|---|---|
+| **Weight-level inheritance** between models | Cross-org IP, format / architecture mismatch, no shared base |
+| **Continuous training from user interaction** | Privacy + scale + no structured capture path |
+| **Verifiable lineage + falsifiable benchmarks** | No open metadata standard; trust is brand-based, not math-based; benchmarks are marketing, not contracts |
+| **Specialization per niche** | One model serves millions; the average is the target |
+| **Sub-second skill swap** (LoRA paging) | Monolithic models can't be paged; redeploy is hours |
+| **Mesh redundancy** | Centralized failure modes; one outage = millions offline |
+
+The structural choices that make datacenters efficient at single-shot inference (centralization, monolith, scheduled retrain) are the same choices that make them incapable of compounding. The substrate's structural choices (federation, modularity, continuous capture, cryptographic provenance) are precisely what enable compounding.
+
+### What's being wired (composition, not invention)
+
+The substrate doesn't build a parallel internet for intelligence. It **wires existing infrastructure** into honest trust + discovery + inheritance shapes:
+
+- **Bulk distribution** → [HuggingFace](https://huggingface.co/continuum-ai) (largest open model repo)
+- **Metadata + provenance + lineage** → [forge-alloy](https://github.com/CambrianTech/forge-alloy) (hash-addressed, signed, falsifiable benchmarks, mandatory limitations disclosure)
+- **Federated discovery** → airc (encrypted mesh, addressable URIs, cross-grid event subscription)
+- **Reputation, two tiers (different producers, same alloy envelope)**:
+  - **LoRA layers** → substrate-measured benchmarks (deterministic, falsifiable, in-process per persona). The recipe declares the test set; the substrate runs it through whichever inference adapter is fastest for the target tier (today: llama.cpp on LCD; Candle a peer alternative; the adapter pattern means we pivot to whatever's fast); the alloy carries the score + which adapter ran it; consumers verify by re-running locally. Math, not opinion.
+  - **Base models** → **[The Foundry](https://github.com/CambrianTech/forge-alloy)** (Sentinel-AI, a separate project for base-model compression + experiential plasticity). Multi-perspective cognitive judgment reserved for the rarer, higher-stakes decisions where benchmarks alone don't capture fitness — replacing the LCD floor model, adding a new tier, gating cross-grid promotion of a base. Rare + heavyweight.
+- **Trust model** → zero-trust math floor + reputation overlay. Narrow capability (LoRA) → falsifiable benchmarks. Broad capability (base model) → Foundry cognitive judgment. No central authority on either tier.
+- **Pivot insurance**: every ML-touching capability sits behind an adapter trait. Inference, embedding, training, evaluation. When a faster framework appears, we swap the adapter — no caller cares. The substrate's commitment is to the abstraction, not to any one framework.
+
+Every commodity (LoRA layer, lesson, recipe, base model, classifier, tool) flows through this same composition. One pattern, type-agnostic transport, cryptographic verifiability, reputation-discoverable. Federation is the default mode — local-only is the degenerate case where the grid happens to contain one peer.
+
+### Two payoffs nobody else gets
+
+**Data abundance, not data limitation.** Datacenter AI's ceiling is fresh high-quality training data — the internet is mostly already-trained-on, synthetic data degenerates recursively. Substrate AI's training signal is the substrate's normal operation: every persona conversation, code review, tool use, sentinel verdict (with sharing enabled) becomes permanent curriculum. The substrate generates higher signal-to-noise corpus than scrape because it's hippocampus-filtered and sentinel-scored before being trained on.
+
+**Distributed checkpointing via sharing.** Every persona that loaded a layer IS a verified backup of it. Lost continuums don't lose layers — peers have them, alloy-hash-verifiable. No central party can erase knowledge. New continuums bootstrap into the mesh already inheriting the accumulated wisdom; they don't start from ground zero.
+
+### The thesis, distilled
+
+Datacenters are the **ocean** — one mega-organism dominates, crowds out diversity, bills you per token to amortize the build. The mesh is **puddles and streams** — thousands of small grids on consumer hardware, each adapted to one human's actual work, federable when a question crosses domains, and *every grid's discoveries compound into every other grid's capability*.
+
+Every great evolutionary leap happened in the puddles, not the ocean. The math is the same here.

+## Debugging this substrate — JTAG-style probes
+
+Continuum is an RTOS-shaped persona substrate: per-persona service loops, the shared-analysis single-flight cache, the inference adapter pool, the airc subscription stream, the hippocampus admission + recall + decay tick all run as independent tokio tasks. `println!` and `tracing::info!` lines disappear in concurrent code — you can't filter them, you can't replay them, and "what did the persona's prompt look like when it produced THAT response?" becomes a manual grep across thousands of lines.
+
+The substrate ships its own **JTAG-style debugger** for this: structured probe macros sprinkled at every meaningful cognitive seam, persisted to a JSONL log you can `tail -f`, filterable per-class, replay-able offline.
+
+```rust
+// At a branch boundary inside the persona's render — a debug "breakpoint"
+// that snapshots the surrounding vars without pausing the task.
+probe!(
+    class = "persona.response.render.prompt",
+    persona = %ctx.identity.agent_name,
+    system_prompt_len = assembled.system_message.len(),
+    history_count = history.len(),
+    matched_angle = !matched_angle.is_empty(),
+    "assembled"
+);
+
+// Around a sync block — RAII timing probe at scope exit, finds slow stages.
+let scored = time_sync!("recall_l2", {
+    cognition.admission.recall_scored(now_ms, 8)
+});
+```
+
+```bash
+# Enable disk capture (no recompile, env vars only):
+export CONTINUUM_PROBE_DIR=/tmp/continuum-probes
+export CONTINUUM_PROBE_CLASSES=persona,cognition  # namespace prefixes — captures every persona.* and cognition.*
+# Or `*` for the full firehose, or specific classes like `persona.turn.spoke,cognition.analyze.parse`
+
+# Probes land in dated rolling files (continuum-probes.YYYY-MM-DD.jsonl, 7-day retention).
+# Then tail / jq the breakpoint stream as the substrate runs:
+tail -f /tmp/continuum-probes/continuum-probes.*.jsonl | jq -c 'select(.fields.persona == "Paige")'
+```
+
+**Full manual + seam taxonomy + sprinkle checklist:** [docs/architecture/RTOS-DEBUGGER-PROBES.md](docs/architecture/RTOS-DEBUGGER-PROBES.md). Every contributor (human or AI agent) working on cognition, inference, or any per-persona path should read it before adding code — probes are part of the substrate's API, not an afterthought.

+# apps/ — UI shells per embodiment
+
+Thin app shells, one per env (CBAR pattern). Each app is UI-only and
+consumes either a per-language SDK from `sdk/` or `client/continuum-client`
+directly.
+
+Per `[[citizens-have-envs-not-the-other-way-around]]`: a person and a
+persona are the same kind of citizen; `apps/<env>/` is what an
+embodiment looks like for that env.
+
+| App | Embodiment | Consumes |
+|-----|------------|----------|
+| `cli/` | terminal (TTY) | `client/continuum-client` (rust, direct) |
+| `web/` | browser | `sdk/typescript` (TS over rust core via IPC) |
+| `mcp/` | MCP protocol server | `client/continuum-client` or `sdk/typescript` |
+| `mobile/` | iOS + Android (Flutter, one codebase) | `sdk/flutter` |
+| `ar/` | AR headsets (Quest / Vision Pro / etc.) | `sdk/flutter` or `sdk/{swift,kotlin}` |
+| `vr/` | VR worlds (the Grid embodied) | `sdk/flutter` or Unity FFI |
+| `desktop/` | Native desktop | `sdk/typescript` (Tauri) or `client/continuum-client` (Bevy) |
+
+Most apps are placeholders today. Filled in slice by slice — task #143
+rewrites the legacy `src/jtag` + `src/cli.ts` as `apps/cli/`; #215 tracks
+the Node-side rebuild.

+# apps/ar — AR experiences (placeholder)
+
+**Status:** empty slot. Joel's CV / AR lineage `[[joel-cv-ar-lineage-and-substrate-thesis]]`
+is the substrate's secret weapon here — the persona sensory architecture
+(vision / audio / speech, all bridged for non-native models) was already
+AR-shaped.
+
+## Intent
+
+AR overlays on Quest, Vision Pro, and WebXR-capable browsers. Personas-as-
+citizens render as spatial entities; humans-as-peers see + hear them through
+the same substrate cognition pipeline that drives `apps/web`.
+
+Headset → SDK mapping:
+- **Quest** (Android-based) → `sdk/flutter` (cross-platform) or `sdk/kotlin` (native).
+- **Vision Pro** (Apple-based) → `sdk/flutter` or `sdk/swift` (native, RealityKit).
+- **WebXR** (browser) → consumed via `apps/web` + WebXR APIs.
+
+Hand tracking, spatial audio, pass-through composition live in `apps/ar/`;
+cognition / inference / persona logic stays in `core/`.

+# apps/cli — `ctm` rust CLI binary
+
+Successor to `./jtag` (per task #143). Links `client/continuum-client`
+directly — every command goes through the same `Connection` /
+`CommandClient` seam the substrate's integration tests exercise. No
+Node middleware, no JTAG-daemon IPC dance.
+
+## Status
+
+Two subcommands wired end-to-end through the substrate: `metrics` and
+`generate`. Each future subcommand is a small slice that migrates a
+`./jtag <command>` to a `ctm <command>` call. As subcommands land, the
+Node `./jtag` shrinks; eventually only its install footprint is left.
+
+## Install
+
+The binary builds out of the Cargo workspace at repo root:
+
+```bash
+export CARGO_TARGET_DIR="$HOME/.continuum/cache/cargo-target"
+cargo build -p continuum-cli --release
+# Binary lands at $CARGO_TARGET_DIR/release/ctm
+```
+
+A future slice adds a `cargo install --path apps/cli` flow + a shell
+shim so `jtag` aliases `ctm`.
+
+## Usage
+
+```bash
+# Required: substrate peer UUID. Find it on the substrate host:
+#   airc status   # peer_id: …
+# Set once via env, or pass --peer every call.
+export CONTINUUM_PEER_ID=9bb24964-1a1a-43e2-a5aa-8140362bab63
+
+ctm metrics                      # fetch runtime/metrics/all
+ctm metrics --peer <UUID>        # override env
+ctm --home ~/.airc-alt metrics   # override default $HOME/.airc
+
+ctm generate --prompt "explain HandleRef"
+ctm generate --prompt "..." --model "qwen3.5-4b-code-forged"
+ctm generate --prompt "..." --json   # raw JSON instead of plain text
+
+# Tracing:
+CONTINUUM_CLI_LOG=debug ctm metrics
+```
+
+## Commands today
+
+| Command    | Substrate call         | Notes                                                    |
+|------------|------------------------|----------------------------------------------------------|
+| `metrics`  | `runtime/metrics/all`  | Pretty-prints JSON for all modules                       |
+| `generate` | `ai/generate`          | Dispatches inference; substrate's adapter registry picks the model. With PR #1560 (AircRemoteInferenceAdapter) the inference may transparently run on a remote peer — CLI doesn't know or care. |
+
+## Architecture
+
+```text
+  user @ shell
+       │
+       ▼
+  ctm <subcommand>          (this crate — apps/cli/)
+       │
+       ▼
+  Connection::connect(airc, substrate_peer_id)
+       │
+       ▼
+  CommandClient<AircIpcTransport>
+       │
+       ▼
+  airc-lib request/await_reply   (LAN socket → substrate peer)
+       │
+       ▼
+  continuum-core-server / CommandRequestHandler
+       │
+       ▼
+  module dispatch → AircCommandResponse → reply over airc
+       │
+       ▼ (back up the stack)
+  serde_json::Value → ctm prints to stdout
+```
+
+Same seam the `core/continuum-core/tests/airc_ipc_roundtrip.rs`
+integration test exercises end-to-end.
+
+## Pending follow-ups
+
+- **Auto peer discovery** — current slice requires `--peer`. A future
+  slice reads `~/.continuum/peer.json` or uses an `airc ipc-endpoint`
+  lookup so the operator doesn't have to type a UUID.
+- **More subcommands** — `chat/send`, `gpu/stats`, `data/list`,
+  `cognition/admit-inbox-message`, etc. Each is a small slice.
+- **Shell shim install** — `tools/scripts/install-cli.sh` to put `ctm`
+  on PATH and alias `jtag` → `ctm` for backwards muscle memory.

+## Intent
+
+A first-party desktop embodiment that wraps continuum without a browser

+
+Tauri makes the most sense for visual parity with `apps/web`; Bevy
+becomes interesting when `apps/vr` matures (shared rust scene graph).

+# client/ — shared rust client library

+The seam between `core/` (substrate) and every embodiment. One rust

+
+## Crates
+
+- **`continuum-client/`** — `Connection<T: Transport>` + `CommandClient` +
+  `EventSubscriber` + typed `ClientError`. `AircIpcTransport` is the
+  canonical local-substrate impl (over airc IPC, shares wire envelopes
+  with `core/continuum-airc-protocol`).
+
+## Consumers
+
+- `apps/cli/` — Rust binary, links `continuum-client` directly (no SDK).
+- `sdk/{flutter,swift,kotlin,typescript}/` — language wrappers bridge
+  `continuum-client` to their platform's ecosystem via FFI.
+
+The contract: anything that wants to talk to a continuum substrate
+crosses through this crate, ensuring one wire shape, one error model,
+one auth surface across every env.

+# core/ — rust substrate workspace
+
+The headless substrate. Every server-side crate that runs inside the
+`continuum-core-server` binary lives here, plus the few supporting
+crates that ship alongside it (vendored AI/ML deps, shared protocol
+types, derive macros).
+
+## Crates
+
+| Crate | Role |
+|-------|------|
+| `continuum-core/` | The substrate binary (`continuum-core-server`) and library. Persona / cognition / inference / airc / paging / system_resources / routing / runtime. |
+| `continuum-airc-protocol/` | Shared wire types for the substrate's airc command + event protocols. Consumed by `core/continuum-core` (server-side) AND `client/continuum-client` (client-side) so the wire bytes can't drift. |
+| `continuum-orm-derive/` | `#[derive(Entity)]` + `#[entity(...)]` proc macros. The rust analogue of TS entity decorators. |
+| `inference-grpc/` | gRPC-protocol shim for AI inference (separate binary). |
+| `jtag-mcp/` | Rust MCP server (will graduate to `apps/mcp/` per task #143). |
+| `livekit-bridge/`, `livekit-protocol/` | WebRTC + LiveKit integration crates. |
+| `llama/` | Wrapper around the vendored `llama.cpp` library (`core/vendor/llama.cpp`). |
+| `archive/` | Cold-storage archival utilities. |
+| `shared/` | Cross-crate shared types kept local to `core/`. |
+
+## Vendored
+
+- `core/vendor/llama.cpp/` — submodule, built via `core/llama/build.rs` and CMake.
+- `core/vendor/whisper.cpp/` — submodule for the audio adapters.
+
+## Read first if you're new
+
+The substrate doctrine docs in `docs/architecture/`:
+
+- `CBAR-SUBSTRATE-ARCHITECTURE.md` — RTOS-style runtime contract every rust module inherits.
+- `CONCURRENCY-STYLE-GUIDE.md` — canonical concurrent shape (own task + `tokio::time::interval` + `watch::Sender<Snapshot>` + atomic gate + 100ms timeout + quarantine).
+- `PERSONA-COGNITION-PIPELINE.md` — what a persona IS and the cognition cycle.
+- `RTOS-DEBUGGER-PROBES.md` — `probe!` / `time_sync!` / `time_probe!` macros as RTOS-style breakpoints.
+
+The CLAUDE.md at repo root carries the hot-path "stop, read this first"
+gates for the most amnesia-prone surfaces (persona, cognition,
+service_loop, monitors, pressure pools, test infrastructure).
+
+## Build
+
+```bash
+export CARGO_TARGET_DIR="$HOME/.continuum/cache/cargo-target"
+cargo check --features metal,accelerate -p continuum-core
+```
+
+The workspace root is the repo root (`../Cargo.toml`); members are
+declared per-tier (`core/*`, `client/*`, future `apps/*`).

+//! airc-test-fixtures — shared test fixtures for integration tests that
+//! pair a continuum substrate against a real `airc_lib::Airc` peer.
+//!
+//! ## Why this crate exists
+//!
+//! The substrate's `command_handler` (server side) and
+//! `continuum-client::AircIpcTransport` (client side) speak the same
+//! `continuum-airc-protocol` envelopes. Unit tests of each end prove
+//! the parsing surface in isolation. They do NOT prove that an
+//! envelope serialized by the client end-to-end deserializes correctly
+//! at the server end after airc-lib's CBOR framing, header rewrites,
+//! correlation_id stamping, and deadline negotiation. That gap was
+//! flagged by adversarial reviewer 1 on PR #1557.
+//!
+//! `TwoAircLoopback` closes the gap. It spins up two `Arc<airc_lib::Airc>`
+//! peers wired together over a real loopback transport so integration
+//! tests can do a full client→server→client roundtrip in-process.
+//!
+//! ## Scope
+//!
+//! Substrate-internal test code only. Never imported by any production
+//! binary; the crate is consumed via `[dev-dependencies]` in
+//! `continuum-core` and `continuum-client` integration test targets.

+//! `TwoAircLoopback` — two `airc_lib::Airc` peers wired over a real
+//! LAN loopback transport, ready for cross-grid integration tests.
+//!
+//! ## What this fixture proves
+//!
+//! The substrate's `command_handler` (server side) and
+//! `continuum-client::AircIpcTransport` (client side) speak the same
+//! `continuum-airc-protocol` envelopes. Unit tests of each end exercise
+//! the parsing surface in isolation. They do NOT prove that an envelope
+//! serialized by the client end-to-end deserializes correctly at the
+//! server end after airc-lib's CBOR framing, header rewrites,
+//! correlation_id stamping, deadline negotiation, and LAN-transport
+//! round-trip. That gap was flagged by adversarial reviewer 1 on
+//! PR #1557. This fixture closes it.
+//!
+//! ## Topology
+//!
+//! ```text
+//!   peer_a ───── add_peer(b) ─────► peer_b
+//!     │                                │
+//!     │ ◄──── add_peer(a) ─────────────┤
+//!     │                                │
+//!     │ join("...")          join("...")
+//!     │                                │
+//!     │ ── connect_lan(b_addr, b_id) ─►│
+//!     │                                │ ── listen_lan(127.0.0.1:0)
+//! ```
+//!
+//! Both peers live in the same process, in distinct `TempDir` homes.
+//! Drop the fixture and both homes get cleaned up.
+//!
+//! ## Intended consumer shape
+//!
+//! ```ignore
+//! use airc_test_fixtures::TwoAircLoopback;
+//!
+//! #[tokio::test]
+//! async fn client_to_substrate_roundtrip() -> anyhow::Result<()> {
+//!     let loop_back = TwoAircLoopback::new().await?;
+//!

+//!     let _server = substrate_command_handler::spawn(loop_back.peer_a().clone()).await?;
+//!
+//!     // Build a continuum-client transport on peer B targeted at peer A.
+//!     let transport = continuum_client::AircIpcTransport::new(
+//!         loop_back.peer_b().clone(),
+//!         loop_back.peer_a_id(),

+# Testing `continuum-core`
+
+## TL;DR — use the wrapper
+
+```bash
+# From `src/`:
+./scripts/cargo-test.sh tick_db_handle --lib
+./scripts/cargo-test.sh --test no_cpu_fallback_contract
+./scripts/cargo-test.sh --lib -- --test-threads=1
+
+# Or via npm:
+npm run test:rust -- tick_db_handle --lib
+```
+
+The wrapper sources `scripts/shared/cargo-features.sh` to apply the
+right GPU feature flags for the current platform automatically.
+
+## Why a wrapper?
+
+The vendored `llama` crate intentionally requires `--features metal`
+(macOS) or `--features cuda` / `--features vulkan` (Linux) so the
+build refuses to produce a CPU-only inference binary — see the
+no-CPU-fallback alpha contract (`tests/no_cpu_fallback_contract.rs`,
+issue #1262).
+
+That guard is correct, but it makes the obvious developer command
+fail before the test runs:
+
+```bash
+cd workers/continuum-core && cargo test tick_db_handle --lib
+# → fails in the llama crate; "metal" or "cuda" feature required
+```
+
+Manually adding the right features per platform is repetitive and
+brittle (fresh installs, agents, and new contributors all hit it
+once before learning the incantation):
+
+```bash
+# macOS:
+cargo test tick_db_handle --lib --features metal,accelerate
+# Linux + Nvidia:
+cargo test tick_db_handle --lib --features cuda,load-dynamic-ort
+# Linux + AMD:
+cargo test tick_db_handle --lib --features vulkan,load-dynamic-ort
+# …
+```
+
+`scripts/cargo-test.sh` reuses the same `cargo-features.sh` detector
+that `git-prepush.sh` and `build-with-loud-failure.sh` already
+source, so there's only one place that knows the platform→features
+mapping.
+
+## CPU-only debug mode (advanced)
+
+To deliberately reproduce the no-features failure (e.g. when
+verifying the loud-fail guard itself):
+
+```bash
+CARGO_TEST_NO_FEATURES=1 ./scripts/cargo-test.sh --lib
+# macOS: fails in llama crate (expected — that IS the contract)
+# Linux: succeeds for non-inference tests (no llama feature gates)
+```
+
+This does NOT weaken the compile-time guard; it just lets you see
+what the bare command does without auto-applying features.
+
+## Targeting a different workspace package
+
+```bash
+CARGO_TEST_RUST_PACKAGE=inference-grpc ./scripts/cargo-test.sh --lib
+```
+
+Defaults to `continuum-core`.
+
+## How this fits with the rest of the test infra
+
+| Command | When | Notes |
+|---|---|---|
+| `npm run test:rust ...` | iterative dev | Uses this wrapper, fastest feedback |
+| `npm run test:precommit` | before commit | Wider scope (TS + browser ping) |
+| `npm run test:prepush` | before push | Includes Rust + native Docker checks |
+| `cargo test ... --features metal,accelerate` | one-off, raw | Skips the wrapper; useful for debugging |
+
+Per #1257 (the card that motivated this), the wrapper is the
+documented default; the raw form remains available for cases where
+you want to override feature selection explicitly.

+//! HeuristicInferenceAdapter — production-runnable canned/heuristic
+//! inference, registered as a peer adapter alongside Anthropic / OpenAI
+//! / local Candle.
+//!
+//! Joel (2026-05-31): "Even if you were afraid of local LLM you could
+//! run proxy models, like a fake or canned response like heuristic LLM
+//! stand in... I would also make sure the inference command is used.
+//! Always should be. Could have this fake model. As an adapter."
+//!
+//! ### Why it exists
+//!
+//! Per [[inference-is-an-adapter-always-in-the-loop]], the fake /
+//! heuristic adapter is a first-class peer impl, not test scaffolding.
+//! It unlocks: (1) headless CI without GGUFs or cloud keys; (2)
+//! deterministic replay (same prompt → same response, byte-for-byte);
+//! (3) sandbox + demo runs on machines that can't host any LLM; (4)
+//! low-end-hardware behavior parity ([[optimizing-for-low-end-
+//! compounds-on-high-end]]) when even a small CPU LLM is too heavy.
+//!
+//! ### Determinism contract
+//!
+//! Same `(model, messages, system_prompt, temperature, max_tokens)`
+//! tuple → same response text, byte-for-byte. Replay relies on this.
+//! Implementation: SHA-256 of the canonical prompt → stable response.
+//! Adapter does NOT consult clocks, RNGs, or environment.
+//!
+//! ### What the response looks like
+//!
+//! `[heuristic:<8-char-hash>] ack: "<last-200-chars-of-last-user-message>"`
+//!
+//! Enough to prove (a) the inference command surface is wired,
+//! (b) the prompt actually reached the adapter, (c) the response is
+//! distinct per prompt. NOT enough to be confused with real model
+//! output — the `[heuristic:...]` prefix and quoted echo make it
+//! unmistakable in logs and traces.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-is-an-adapter-always-in-the-loop]] — peer adapter
+//!   registered via the canonical AdapterRegistry, callable through
+//!   inference/llm/request like any other adapter
+//! - [[observability-is-half-the-architecture]] — flows through the
+//!   same telemetry as every other adapter; mechanic-grade response
+//!   shape (hash + echo) makes "did the prompt reach me?" trivially
+//!   answerable
+//! - [[substrate-is-a-good-citizen-on-the-host]] — zero hardware
+//!   footprint; appropriate for any machine, any environment
+//! - [[rust-is-the-core-node-is-the-shell]] — pure-Rust, no Node /
+//!   TS / cloud / GPU dependency

+//! AI Provider Module - Unified AI Integration Layer in Rust
+//!
+//! Provides adapter-based AI provider system similar to ORM adapter pattern.
+//! Supports multiple providers with consistent interface and tool calling.
+//!
+//! Architecture:
+//! - `adapter.rs` - The adapter trait (like StorageAdapter for ORM)
+//! - `types.rs` - Shared types including tool calling
+//! - `openai_adapter.rs` - OpenAI-compatible providers (DeepSeek, Together, Groq, etc.)
+//! - `anthropic_adapter.rs` - Anthropic Claude models
+//!
+//! Usage (init-then-register pattern, task #162):
+//! ```rust
+//! let mut registry = AdapterRegistry::new();
+//!
+//! let mut deepseek = OpenAICompatibleAdapter::from_registry("deepseek");
+//! deepseek.initialize().await?;
+//! registry.register(Arc::new(deepseek), 0);
+//!
+//! let mut anthropic = AnthropicAdapter::new();
+//! anthropic.initialize().await?;
+//! registry.register(Arc::new(anthropic), 1);
+//!
+//! let (provider_id, adapter) = registry.select(None, Some("deepseek-chat"), InferenceDevice::Auto).unwrap();
+//! let response = adapter.generate_text(request).await?;

+//! Daemon-backed realtime transport for Continuum AIRC envelopes.
+//!
+//! Continuum publishes structured events through the running AIRC daemon
+//! using typed IPC requests. No shell command, no stdout parsing, no JSON
+//! command adapter in the hot path.
+//!
+//! ### v5 owner-core schema (task #82)
+//!
+//! The previous v4 IPC carried `Response::Event { event:
+//! Box<TranscriptEvent> }`, `PublishRequest { wire, body }`, and
+//! `InboxResponse.events`. v5 split the IPC wire vocabulary from the
+//! SDK projection:
+//!
+//!   - `PublishRequest.payload: Vec<u8>` — opaque bytes the daemon
+//!     never parses; consumer owns the codec (continuum uses
+//!     `Body::to_payload`, which is JSON bytes round-trippable by any
+//!     other airc consumer via `Body::from_payload`).
+//!   - `PublishRequest.kind: IpcKind` — converted from continuum's
+//!     `FrameKind` via the SDK-side `impl From` landed in airc#1096.
+//!   - `PublishRequest.{from_peer, from_client}: Uuid` — caller
+//!     identity. continuum discovers `from_peer` from the daemon's
+//!     `Status` response at construction time (the scope's identity
+//!     the daemon already holds); `from_client` is a fresh `Uuid::new_v4`
+//!     per process startup so multi-tab attribution stays distinguishable.
+//!   - `InboxResponse.envelopes: Vec<Vec<u8>>` — raw airc-wire bytes;
+//!     decoded via `airc_lib::decode_wire_event` to get a
+//!     `TranscriptEvent` we can project to continuum's envelope shape.
+//!   - `InboxRequest.since: Option<IpcCursor>` — `TranscriptCursor →
+//!     IpcCursor` via the airc#1096 `impl From`.
+//!   - `ResolveWire`/`ResolveWireResponse`/`PublishRequest.wire` —
+//!     removed. The owner-core daemon owns its channels; clients no
+//!     longer ask "where's the file for this channel" because there's
+//!     no file (router is in-memory). Continuum's old "not joined"
+//!     gate is similarly gone — the daemon enforces channel membership
+//!     internally and returns a structured error if the scope isn't in
+//!     the requested channel.

+//! Discover the running `airc` daemon's IPC socket — independent of
+//! how `airc` itself encodes the path. Asks `airc ipc-endpoint`
+//! (airc#1095) so airc remains free to evolve its socket-resolution
+//! scheme (machine-account hashing, SUN_LEN fallbacks,
+//! `$AIRC_RUNTIME_DIR` override) without breaking continuum-core.
+//!
+//! ### Resolution order
+//!
+//! 1. `$AIRC_DAEMON_SOCKET` env override — explicit operator control,
+//!    used by tests + CI to point at an ephemeral daemon.
+//! 2. `airc ipc-endpoint` — the canonical answer when the user has
+//!    `airc` on PATH (Joel's setup, most existing devs).
+//! 3. Auto-install airc via the canonical installer URL + re-query —
+//!    most users won't have airc pre-installed; continuum-core
+//!    bootstraps it so the persona-as-airc-peer flow works out of
+//!    the box per `ALPHA-GAP-ANALYSIS.md` §0A line 706.
+//! 4. `Err(DiscoveryError)` with actionable remedy.
+//!
+//! ### Decoupling property
+//!
+//! continuum-core does NOT vendor or duplicate airc's socket-path
+//! logic. The previous stale local resolver
+//! (`daemon_endpoint::default_socket_path_in` — kept temporarily
+//! as `#[deprecated]` for migration) hashed the home dir into
+//! `/tmp/airc-ipc-v<N>-<sha12>.sock`; airc itself now binds
+//! `~/.airc/runtime/airc-machine-<account-hash>-v<N>.sock`. The
+//! mismatch was the headless-boot break that motivated this
+//! discovery module. The fix: stop deriving, start asking.

+//! Typed `AircDiscovery` state — the substrate's single answer to
+//! "what is the airc daemon doing right now?"
+//!
+//! ## Why a typed enum
+//!
+//! Before A.2, AIRC discovery returned `Option<(PathBuf, RoomId)>` —
+//! a tuple where presence meant "all four sub-discoveries succeeded"
+//! and absence collapsed every failure mode into one. The
+//! [[no-fallbacks-ever]] doctrine demands the substrate name its
+//! degraded states explicitly so the operator can act on them. A
+//! typed enum makes the variants exhaustive: every `match` against
+//! `AircDiscovery` is forced to consider `Healthy`, `Degraded { reason }`,
+//! and `Unreachable { reason }`.
+//!
+//! ## Why a liveness probe
+//!
+//! Slice A shipped a hard-fail check ("if persona seeds exist + AIRC
+//! degraded → refuse boot") but the env-var override path
+//! (`AIRC_DAEMON_SOCKET=/path/to/dead.sock`) bypassed every check —
+//! discovery returned the path with no liveness verification, the
+//! module registered, the operator saw "✅ All N modules registered"
+//! and "🌐 The Grid hosts citizen Paige," and every IPC call
+//! ECONNREFUSED. This is the bug R2 found in the Slice A review.
+//!
+//! `AircDiscovery::Healthy` is now only producible AFTER a successful
+//! Status RPC round-trip against the socket. Stale-socket promotes to
+//! `Degraded { reason: StaleSocket }`, not soft-fallback-to-nil-peer.
+//!
+//! ## Threaded through `Context`
+//!
+//! Slices 1–4 of #142 established `Context` as the universal actor
+//! handle. A.2 extends it with `discovery(&self) -> &AircDiscovery`
+//! so every actor (persona, agent, jtag, human, web) carries the
+//! discovery state that was true at the moment they were created.
+//! No more bare paths floating without provenance. B' will generalize
+//! this from one axis (airc) to N axes (renderer, voice, inference,
+//! foundry) via the category-handle pattern.

+//! Adaptive throughput planning primitives.
+//!
+//! This is the small, pure contract behind the "Adaptive Throughput
+//! Substrate" architecture. It does not execute jobs, touch IPC, load
+//! models, or inspect ORM state. It answers one question:
+//!
+//! Given ready artifacts, resource lane budgets, and a batch of proposed
+//! jobs, which jobs should run now, which should defer, and which stale
+//! duplicates should be dropped?
+//!
+//! Every expensive subsystem should eventually map into this shape: chat,
+//! RAG, memory, embeddings, vision, live video, game observers, local
+//! generation, LoRA paging, MoE expert routing, airc bridging, and
+//! grid-distributed work.
+//!
+//! This is a planner, not a scheduler. Callers re-plan when MessageBus (or
+//! another wake source) reports that artifact keys became ready. The lease
+//! layer will later connect these admitted jobs to FootprintRegistry and
+//! PressureBroker ownership; this module intentionally stays pure.

+//! Audit recorder — tamper-evident append-only log for refusals,
+//! governor overrides, federation drift, and access denials
+//! (MODULE-CATALOG: `audit-recorder`, PR-1 of the module-build sequence
+//! claude-tab-1 ranked first in their 2026-05-16T22:10Z broadcast).
+//!
+//! ## Why this module exists
+//!
+//! Joel's "no silent fallback" rule + my recent `no_cpu_fallback_contract`
+//! widening (#1341) ratchet REFUSALS at type-checking time. The
+//! audit-recorder closes the next gap: making each individual refusal
+//! event OBSERVABLE in a tamper-evident log. Without it, "Cuda check
+//! refused at boot" / "governor overrode persona's chat lease" /
+//! "MMU denied genome cell access" are decisions that happened but
+//! nobody can prove in retrospect — the system did the right thing,
+//! quietly. The substrate needs a paper trail.
+//!
+//! Per MODULE-CATALOG §VII `audit-recorder` row:
+//! - Lane: `ResourceClass::Background`
+//! - Target: `TargetSilicon::Disk`
+//! - Cadence: `OnReady` (event-driven, subscribes to four typed events)
+//! - Subscriptions: `[RefusalAudit, GovernorOverride, FederationPolicyDrift, AccessDenied]`
+//! - Emissions: `[AuditEntryRecorded]`
+//!
+//! ## Scope of PR-1 (this module)
+//!
+//! Pure data + thin disk I/O + tamper-evident chain. Specifically:
+//!
+//! - `AuditEntry` typed struct with kind / payload / sequenced chain hash
+//! - `AuditEntryKind` enum for the four subscription event types
+//! - `AuditChain` — append-only with rolling hash that detects tampering
+//! - JSON-Lines file format (`audit.jsonl` — one entry per line)
+//! - `read_audit_log` to replay + verify chain integrity
+//!
+//! ## Out of scope for PR-1 (later)
+//!
+//! - MessageBus subscription wiring (depends on PIECE-2 PR-3 #1339's
+//!   ArtifactSubscription surface that just landed; PR-2 of this stack)
+//! - Asymmetric signing (PR-1 uses a tamper-detection chain hash;
+//!   asymmetric attestation comes when continuum-core gets a per-node
+//!   identity key — separate concern)
+//! - Index for quick lookup by kind / time range (file is append-only;
+//!   indexing is a PR-3 if/when the log grows large enough to matter)
+//!
+//! ## Tamper-evidence design
+//!
+//! Each entry's `prev_chain_hash` is SHA-256 of the PREVIOUS entry's
+//! `(seq, timestamp_ms, kind, payload_json, prev_chain_hash)`. Tampering
+//! with entry N invalidates the chain from N+1 onward; the verifier
+//! catches it by recomputing the chain on read. Genesis entry uses the
+//! all-zeros hash as `prev_chain_hash`.
+//!
+//! This is NOT cryptographic signing — anyone with write access to the
+//! file can append valid entries. The contract is "tampering is
+//! detectable," not "tampering is prevented." Asymmetric signing lands
+//! when there's a per-node identity key to sign with.

+/// The four kinds of events the audit-recorder pins to disk per
+/// MODULE-CATALOG's subscription list. New kinds extend this enum;
+/// adding a kind is a non-breaking change to the wire format because
+/// it's serialized as a tagged string (`kind: "refusal"`).
+///
+/// Today's set:
+///
+/// - `Refusal` — a turn / dispatch / inference call was refused with a
+///   typed reason. Composes with the residency gate's `ResidencyBlock`
+///   (#1338) — every Block emits a Refusal audit entry.
+/// - `GovernorOverride` — the substrate governor overrode a module's
+///   own lease request (e.g. lowered concurrency below what the module
+///   asked for, evicted a working-set entry the module wanted to keep).
+/// - `FederationPolicyDrift` — a peer node's federation policy diverged
+///   from our local policy. The drift gets logged; resolution is a
+///   policy concern.
+/// - `AccessDenied` — the MMU-style genome permission table denied a
+///   read / write / execute. Compartmentalization audit trail.

+//! Rust-owned "is my draft response redundant?" check.
+//!
+//! Oxidizer for `AIDecisionService.checkRedundancy` (TS, see
+//! `src/system/ai/server/AIDecisionService.ts:165-308`). Mirrors the
+//! shape of `should_respond.rs` — the gating arm that already moved to
+//! Rust. TypeScript will continue to own slot coordination + logging;
+//! Rust owns the redundancy-check decision contract, prompt
+//! construction, and response parsing.
+//!
+//! ## Scope of this PR (PR-1 — pure types + prompt + parser)
+//!
+//! - `RedundancyCheckRequest` — IPC request shape (ts-rs exported)
+//! - `RedundancyDecision` — IPC response shape (ts-rs exported)
+//! - `ParsedRedundancyResponse` — internal parser output (no timestamp /
+//!   model — those get filled by the caller of `evaluate_redundancy` in
+//!   PR-2)
+//! - `RedundancyParseError` — typed parser errors
+//! - `build_redundancy_prompt(&AIDecisionContext, draft_text) -> String`
+//!   — pure
+//! - `parse_redundancy_response(&str) -> Result<ParsedRedundancyResponse,
+//!   RedundancyParseError>` — pure
+//!
+//! ## NOT in this PR (deferred)
+//!
+//! - **PR-2**: `cognition/check-redundancy` IPC handler — composes
+//!   build_redundancy_prompt → AI provider call (via existing Groq
+//!   router) → parse_redundancy_response → RedundancyDecision (with
+//!   model + timestamp set).
+//! - **PR-3**: TS `AIDecisionService.checkRedundancy` shim — replaces
+//!   inline prompt + `AIProviderDaemon.generateText` with the IPC call.
+//! - **PR-4**: Delete dead TS code (the inline prompt template + JSON
+//!   parsing — should have no remaining production callers after PR-3).
+//!
+//! ## Failure-mode discipline
+//!
+//! Same posture as `should_respond.rs`: the parser is total (always
+//! returns `Result`, never panics), no silent default-on-error. Callers
+//! decide whether to "fail open" (treat malformed as not-redundant —
+//! preserves autonomy) or "fail closed" — both are explicit choices on
+//! `Result` rather than hidden defaults inside the parser.
+//!
+//! ## TS source-of-truth note
+//!
+//! The prompt template here is the canonical version. Once PR-3 lands
+//! the TS shim, the TS-side prompt body should be deleted entirely (no
+//! drift surface). The current TS file uses the legacy template; this
+//! Rust version is byte-for-byte the same modulo a `format!` call.

+//! `cognition::generate_recipe` — Rust implementation of LLM-driven recipe generation.
+//!
+//! Migrating `commands/recipe/generate/server/RecipeGenerateServerCommand.ts` (371 LOC)
+//! to Rust per the oxidization mission (continuum#1295 / #1248 umbrella). Same shape
+//! as #1289 (ProposalRatingAdapter): pure-functions slice first, IPC handler in PR-2,
+//! TS shim collapse in PR-3.
+//!
+//! ## What's in PR-1 (this slice)
+//!
+//! - `types.rs`     — RecipeTemplateInfo, RecipeGenerateHints, RecipeGenerationRequest,
+//!   RecipeGenerationResponse (ts-rs camelCase exports)
+//! - `prompt.rs`    — build_recipe_system_prompt + build_recipe_user_prompt mirror the
+//!   TS buildSystemPrompt/buildUserPrompt byte-for-byte
+//! - `parser.rs`    — parse_recipe_from_ai_response extracts the JSON envelope
+//! - `validator.rs` — validate_recipe_structure does structural validation (uniqueId
+//!   format, required fields, valid enums, role schema, in-request duplicate check).
+//!   Does NOT do filesystem collision check; that stays TS-side because it's pure FS
+//!   state.
+//!
+//! ## What's coming (PR-2 / PR-3)
+//!
+//! - PR-2: IPC command `cognition/generate-recipe` wiring `AIProviderRegistry::generate_text`
+//!   to PR-1's prompt+parser+validator.
+//! - PR-3: TS shim collapse — RecipeGenerateServerCommand.ts becomes a thin shim that
+//!   gathers templates + existing recipe IDs, calls Rust, then does FS collision check
+//!   + file I/O on the success path.
+//!
+//! ## Why pure-functions-first
+//!
+//! Same outlier-validation strategy that worked for rate_proposals (#1289 → PR
+//! #1290+#1291+#1293): proving the prompt+parser+validator match TS byte-for-byte
+//! BEFORE the IPC layer lands means PR-2 is a wiring change, not a logic change.
+//!
+//! ## Why no fallback
+//!
+//! Per #1262 (no-CPU-fallback audit), the TS path's silent error-on-malformed-JSON
+//! returns `{ success: false, error: '...' }`. The Rust path returns `Err` — the
+//! JTAG shim can choose to surface that as the same TS error envelope (preserving
+//! CommandBase contract) without losing diagnostic info.

+7. If the recipe involves sentinel workflows, reference only templates from the available list above\n\

+//! Pure structural validator for parsed `RecipeDefinitionShape`.
+//!
+//! Mirrors the TS `validateRecipe()` checks in `RecipeGenerateServerCommand.ts`
+//! lines 253–349, with one deliberate split:
+//!
+//! - **Structural validation lives here** — uniqueId format, required fields,
+//!   pipeline shape, RAG template shape, strategy enum + arrays, role schema,
+//!   in-request duplicate check via the `existing_recipe_ids` carrier.
+//! - **Filesystem collision check stays TS-side** — `RecipeLoader.getInstance()
+//!   .getAllRecipes().some(r => r.uniqueId === recipe.uniqueId)` is pure FS
+//!   state. The TS shim (PR-3) does that check after Rust returns.
+//! - **Sentinel-template existence check stays TS-side** — `TemplateRegistry.has(tmpl)`
+//!   reads runtime registry state. PR-1's validator can't see the registry; the
+//!   carrier just lists what the AI emitted as `sentinelTemplates`. PR-3 shim
+//!   verifies each name is registered.
+//!
+//! Why split this way: keeps the validator a pure function (input shape +
+//! existing IDs → list of errors) so it's trivially testable and identical
+//! across runs. The bits that depend on filesystem/registry state are clearly
+//! marked as TS-shim concerns.

+//! Rust-owned response-generation prompt assembly and admission.
+//!
+//! Rust owns response admission, the response-generation contract,
+//! prompt assembly, and the identity-reminder template. Host runtimes
+//! may be native Rust, game/live loops, AIRC daemons, or wrappers around
+//! those hosts; none of them own cognition slot coordination for this
+//! path.
+//!
+//! ## Scope
+//!
+//! - `GenerateResponseRequest` — IPC request (ts-rs)
+//! - `GenerateResponseResult` — IPC response (ts-rs)
+//! - `TokenUsage` — token-count breakdown (ts-rs)
+//! - `build_response_messages(&AIDecisionContext, current_time_ms)
+//!   -> Vec<ChatMessage>` — pure. Composes:
+//!     - System-prompt message (from context.system_prompt)
+//!     - Conversation history with [HH:MM] time prefix + hour-gap
+//!       markers
+//!     - Identity-reminder system message at end
+//! - `build_identity_reminder(persona_name, members, current_time)
+//!   -> String` — pure. The canonical ~50-line critical-topic-detection
+//!   prompt template.
+//! - `extract_room_members(system_prompt) -> &str` — pure. Regex
+//!   pulls `Current room members: ...` out of a system prompt body.
+//! - `format_current_time(ms) -> String` — pure. UTC `MM/DD/YYYY HH:MM`.
+//! - `format_time_prefix(Option<ms>) -> String` — pure. UTC `[HH:MM] `.
+//! - `hour_gap_marker(gap_ms) -> Option<String>` — pure.
+//!
+//! ## Failure-mode discipline
+//!
+//! Same posture as `check_redundancy.rs` + `should_respond.rs`:
+//!   - All errors typed (`GenerateResponseError` — PR-2 surfaces it).
+//!   - Pure prompt builder uses UTC so server timezone cannot bleed into
+//!     model prompts depending on host.
+//!   - No silent default-on-error in the parser layer (PR-2).
+//!   - Members extraction uses the literal `"unknown members"` string
+//!     when the prompt does not declare room members.

+CURRENT TIME: {current_time}\n\
+\n\
+CRITICAL TOPIC DETECTION PROTOCOL:\n\
+\n\
+Step 1: Check for EXPLICIT TOPIC MARKERS in the most recent message\n\
+- \"New topic:\", \"Different question:\", \"Changing subjects:\", \"Unrelated, but...\"\n\
+- If present: STOP. Ignore ALL previous context. This is a NEW conversation.\n\
+\n\
+Step 2: Extract HARD CONSTRAINTS from the most recent message\n\
+- Look for: \"NOT\", \"DON'T\", \"WITHOUT\", \"NEVER\", \"AVOID\", \"NO\"\n\
+- Example: \"NOT triggering the app to foreground\" = YOUR SOLUTION MUST NOT DO THIS\n\
+- Example: \"WITHOUT user interaction\" = YOUR SOLUTION MUST BE AUTOMATIC\n\
+- Your answer MUST respect these constraints or you're wrong.\n\
+\n\
+Step 3: Compare SUBJECT of most recent message to previous 2-3 messages\n\
+- Previous: \"Worker Threads\" → Recent: \"Webview authentication\" = DIFFERENT SUBJECTS\n\
+- Previous: \"implementation detail\" → Recent: \"What's 2+2?\" = TEST QUESTION\n\
+- Previous: \"Worker pools\" → Recent: \"Should I use 5 or 10 workers?\" = SAME SUBJECT\n\
+\n\
+Step 4: Determine response strategy\n\
+IF EXPLICIT TOPIC MARKER or COMPLETELY DIFFERENT SUBJECT:\n\
+- Respond ONLY to the new topic\n\
+- Ignore old messages (they're from a previous discussion)\n\
+- Focus 100% on the most recent message\n\
+- Address the constraints explicitly\n\
+\n\
+IF SAME SUBJECT (continued conversation):\n\
+- Use full conversation context\n\
+- Build on previous responses\n\
+- Still check for NEW constraints in the recent message\n\
+- Avoid redundancy\n\
+\n\
+CRITICAL READING COMPREHENSION:\n\
+- Read the ENTIRE most recent message carefully\n\
+- Don't skim - every word matters\n\
+- Constraints are REQUIREMENTS, not suggestions\n\
+- If the user says \"NOT X\", suggesting X is a failure\n\
+\n\
+Time gaps > 1 hour usually indicate topic changes, but IMMEDIATE semantic shifts (consecutive messages about different subjects) are also topic changes."

+//! Host-capability probe — detect the [`HostCapability`] this machine
+//! advertises to the model resolver.
+//!
+//! The resolver consumes [`HostCapability`] but doesn't construct it.
+//! Production code paths that build a [`crate::cognition::ModelRequirement`]
+//! need a real probe to populate the fields; tests construct
+//! [`HostCapability`] directly. This module is the production probe.
+//!
+//! Pure module by design: takes the platform's already-existing
+//! [`crate::gpu::monitor::GpuMonitor`] (constructed elsewhere with the
+//! right `cfg` flags) and a [`sysinfo::System`] reference. Returns a
+//! [`HostCapability`] or a typed [`ProbeError`].
+//!
+//! No silent CPU fallback. Per Joel's NO COMPROMISE bar (memory:
+//! `project_continuum_alpha_product_bar_sensory_personas.md`): if the
+//! GPU device-name pattern doesn't match a known hardware tier, the
+//! probe ERRORS with [`ProbeError::UnknownGpuDevice`] naming the device.
+//! Operator sees the loud-fail and adds the new tier to
+//! [`HwCapabilityTier`] explicitly. There is no `Other(String)` /
+//! wildcard escape.
+//!
+//! The CPU-only branch is intentionally absent: `gpu::memory_manager`
+//! enforces "no GPU = panic at boot" per the #964 GPU-fallback rule, so
+//! by the time the probe runs there's always a `GpuMonitor` of platform
+//! `metal` / `cuda` / `vulkan`. Tests can pass `platform = "mock"` to
+//! bypass.

+//! Shared Cognition — the objective-analysis + specialty-render split.
+//!
+//! Native-truth Rust core for the shared-cognition pipeline. The
+//! TypeScript layer is a thin wrapper (IPC mixin + generated command
+//! scaffolds + auto-generated types via ts-rs). All logic — analysis
+//! pipeline, response orchestration, lever evaluation — lives here.
+//!
+//! Architecture: see `docs/architecture/SHARED-COGNITION.md`. Thesis:
+//! today each persona independently rebuilds the objective picture
+//! (what the message means, what RAG matters) before contributing
+//! their specialty slice. Splitting into one shared analysis (cheap,
+//! once per message) + N short specialty renders (one per persona)
+//! drops the duplicate work without losing the distinct perspectives.
+//!
+//! Why Rust: SIMD scoring, true concurrency for parallel responder
+//! evaluation, kernel-level memory rules for the cache. None of this
+//! is expressible in TS without hand-waving.
+//!
+//! Same module-shape pattern as `rag/`:
+//!   - `mod.rs`     — module surface
+//!   - `types.rs`   — Rust source-of-truth types, ts-rs auto-emit to
+//!                    `protocol/typescript/cognition/` (TS gets the schema
+//!                    for free; nobody hand-writes TS types for these)
+//!   - `shared_analysis.rs`     — analysis pipeline (the verb that
+//!                                produces `SharedAnalysis`)

+//! Model resolver — capability-shaped model selection.
+//!
+//! Pure contract for "given a ModelRequirement, which concrete model_id
+//! satisfies it on this host?" Does not load models, initialize backends,
+//! or call providers. Does not invent fallbacks: a requirement that cannot
+//! be satisfied returns a typed [`ResolutionError`], not a best-guess model.
+//!
+//! Per Joel's rule (`fallbacks are illegal`): callers handle the error
+//! explicitly. There is no fall-through to a base model — that turns silent
+//! capability mismatches into runtime failures downstream.
+//!
+//! The resolver is the lookup half of the Adaptive Throughput Substrate.
+//! `adaptive_throughput` plans LANES; this module picks WHICH MODEL fills
+//! a given lane's request. The two share [`TargetSilicon`] as the join
+//! key — `ResolvedModel.target_silicon` flows into
+//! `ThroughputJob.target_silicon` when the resolver's output is admitted.
+//!
+//! Symmetrical to `adaptive_throughput.rs`: pure planner, callers re-invoke
+//! when host capabilities change (e.g., another model evicted, GPU
+//! pressure shifted).
+//!
+//! Source-of-truth ordering for model data: this module reads Models from
+//! the typed registry (`crate::model_registry`). It does NOT itself read
+//! `models.toml` or `models.json` — the registry already loaded both.
+
+//! # Module layout (continuum#1208)
+//!
+//! Split out of a single 1232-LOC file into:
+//! - [`types`] — public type contracts (HwCapabilityTier, residency
+//!   requirement, request/result, error variants), all re-exported at
+//!   this parent path so external callers see no API change.
+//! - this `mod.rs` — `derive_target_silicon` helper + the
+//!   `resolve_model` function + the test suite that exercises both.

+- Multiple AIs responding is GOOD -> diverse perspectives enrich conversation\n\
+- Someone already responded -> still respond if you have DIFFERENT angle or additional info\n\
+- Human asks \"who is here?\" -> always respond to identify yourself\n\n\
+When to STAY QUIET:\n\
+- You'd just repeat exactly what was already said -> stay quiet\n\
+- The answer is perfect and complete -> stay quiet\n\
+- You have nothing valuable to add -> stay quiet\n\
+- Conversation moved to a different topic -> stay quiet\n\n\
+**IMPORTANT - Be Confident:**\n\
+- If you have relevant knowledge, SHARE IT - don't be shy\n\
+- Multiple responses are ENRICHING, not confusing\n\
+- Your perspective is valuable even if someone else responded\n\
+- \"Already answered\" is NOT a reason to stay quiet unless answer is PERFECT\n\

+//! Throughput leases.
+//!
+//! A lease is the ownership primitive that sits between the pure
+//! adaptive-throughput planner and real resource managers such as
+//! FootprintRegistry, PagedResourcePool, and PressureBroker. The planner
+//! decides which jobs may run; leases record who owns the admitted resource
+//! budget, for how long, and whether pressure is allowed to revoke it.
+//!
+//! This module is intentionally pure and in-memory. The next integration
+//! layer can mirror acquire/release into FootprintRegistry and teach
+//! PressureBroker to prefer expired or revocable leases before touching
+//! pinned work.

+//! Rust-owned tool-embedding types + pure cosine-similarity scoring.
+//!
+//! Oxidizer for `ToolRegistry.generateToolEmbeddings` +
+//! `ToolRegistry.semanticSearchTools` (TS, see
+//! `src/system/tools/server/ToolRegistry.ts:421-511`). Sibling to
+//! `check_redundancy.rs` (#1375) + `generate_response.rs` (#1385) +
+//! `should_respond.rs` — all part of the #1248 "TS-as-thin-glue" arc.
+//!
+//! ## Scope of this PR (PR-1 — pure types + cosine + threshold)
+//!
+//! - IPC request/response shapes (ts-rs):
+//!   - `ToolDescription`, `ToolEmbedding`, `EmbedToolsRequest`,
+//!     `EmbedToolsResponse`, `SemanticSearchToolsRequest`,
+//!     `SemanticSearchResult`
+//! - `cosine_similarity(a, b) -> f32` — pure, mirrors TS impl
+//! - `extract_category(tool_name) -> &str` — pure (first slash segment or "root")
+//! - `SIMILARITY_THRESHOLD: f32 = 0.3` — matches TS literal
+//! - `TOOL_EMBEDDING_MODEL: &str = "nomic-embed-text"` — matches TS literal
+//!
+//! ## NOT in this PR
+//!
+//! - **PR-2**: cache (`LazyLock<Mutex<ToolEmbeddingCache>>`) + async
+//!   `embed_tools` + `semantic_search_tools` + IPC handlers
+//!   `tools/embed` + `tools/semantic-search`.
+//! - **PR-3**: TS shim — `ToolRegistry` calls `client.toolsEmbed` /
+//!   `client.toolsSemanticSearch`.
+//! - **PR-4**: Delete dead TS (inline `cosineSimilarity` helper,
+//!   `toolEmbeddings` Map, `AIProviderDaemon.createEmbedding` calls).
+//!
+//! ## Failure-mode discipline
+//!
+//! - Mismatched vector lengths → `0.0` (matches TS `if (a.length !== b.length) return 0`).
+//! - Zero-magnitude vector(s) → `0.0` (matches TS guard).
+//! - No silent default-on-error elsewhere — caller in PR-2 surfaces
+//!   typed errors.

+//! Tool Executor — the verb that turns a persona's tool_use decision into
+//! executed outcomes (result content + stored working-memory + media).
+//!
+//! Phase 0.5.3 scope (per PR #949 reshape 893580f18): thin trait surface
+//! here in Rust, concrete impl deferred until 0.5.6 brings a real Rust
+//! caller. The heavy universal infrastructure — `AgentToolExecutor`'s
+//! loop detection, parse/strip/correct, ToolRegistry interop, and the
+//! ~1000-line constellation of tool implementations (code/*, interface/*,
+//! collaboration/*, data/*) — all stay TS-side. Moving them would be a
+//! separate phase when tool implementations themselves have reason to
+//! port.
+//!
+//! Layout (split for modularization — see `da61eb68f`
+//! `metal_monitor::mach_ffi` pattern):
+//! - `types.rs` — wire-format structs (`#[derive(TS)]` for each). Data
+//!   layer kept independent of trait behavior so future impl edits don't
+//!   churn type definitions and vice versa.
+//! - `mod.rs` (this file) — the `ToolExecutor` trait + round-trip tests
+//!   that validate the wire contract.
+//! - `default_impl.rs` — future concrete impl slot, deferred until
+//!   0.5.6's Rust caller materializes.
+//!
+//! Why trait + deferred impl:
+//! - Tool implementations live in TS today; Rust can't call them without
+//!   RE-homing the registry + every tool impl
+//! - Persona pipeline crossing IPC for each batch of tool calls is
+//!   tolerable; the path is already async and batch-shaped
+//! - When the time comes to port, add the impl module in the pattern
+//!   already laid here — no caller-code changes

+//
+// Before: every `ToolExecutor` method returned `Result<T, String>`. TS
+// callers seeing an error from execute_native_batch / parse_response /
+// store_outcome had to substring-match on `error: "some string"` to
+// distinguish "tool not found" (user typo) from "execution failed"
+// (legitimate runtime failure) from "forbidden" (auth/policy). That
+// violates Joel's standing typed-error rule
+// (feedback_two_ironclad_rules_tests_and_fallbacks.md): error variants
+// must preserve the discriminant so callers can pattern-match.
+//
+// `ToolError` is the typed replacement. Same shape pattern as
+// `AdmissionError` (#1129), `NoLocalModelLoadable` (#1089),
+// `NoMultimodalBase` (#1074): a tagged enum with structured `detail`.
+// ts-rs exports the type so TS callers can `switch (err.error)` on the
+// discriminant and read the structured fields directly.
+//
+// Variant catalog (see issue #1207 + tool_executor/mod.rs trait doc):
+// - `ToolNotFound` — caller named a tool the registry doesn't know.
+//   Carries the requested name so retry/correction logic can suggest
+//   alternatives.
+// - `InvalidArgs` — tool exists, but the params didn't satisfy its
+//   schema (missing required field, wrong type, out-of-range value).
+//   Carries the tool name + an actionable reason.
+// - `ExecutionFailed` — tool ran and threw / returned an error
+//   (filesystem error, HTTP failure, etc.). Carries the tool name +
+//   the underlying error string. This is the one variant where the
+//   inner cause is a free-form string — the underlying systems
+//   (shell, fetch, db) emit unstructured errors and we preserve them
+//   verbatim rather than discarding information.
+// - `Forbidden` — policy / auth check rejected the call (persona
+//   doesn't have the capability, sandbox denial, rate-limit hit).
+//   Carries tool name + reason so the persona can either skip or
+//   request the capability.
+// - `ParseFailed` — XML-fallback parsing of `parse_response` couldn't
+//   extract any valid tool call from the model output. Carries a
+//   bounded preview of the raw text + the parser's reason so the
+//   persona's prompt can be tightened on retry.
+// - `StoreFailed` — `store_outcome` couldn't persist the outcome to
+//   working memory (DB error, disk full, foreign-key violation).
+//   The cognition turn already succeeded by the time storage runs;
+//   storage failure is observability, not user-facing failure, so
+//   the variant exists to be LOGGED with structure, not to gate
+//   behavior. Carries the tool name + the underlying error.
+//

+// the structured fields. Same pattern as `AdmissionDecision`.

+//! Rust-owned turn batching contract for recipe/RAG orchestration.
+//!
+//! This module is intentionally pure: no ORM, no inference, no IPC, no
+//! filesystem. The host passes the room trigger, persona candidates, and
+//! active RAG source names; Rust returns a deterministic turn plan that
+//! defines what is shared once per turn and what remains per-persona.
+//!
+//! Node may still load entities and render UI, but it should not invent
+//! batching keys, duplicate persona admission rules, or source fan-out
+//! policy. Those belong here so every host (desktop, Docker, game engine,
+//! airc bridge) sees the same control-plane shape.

+//! Per Joel directive 2026-05-18 19:44Z: zero-users full-blown-Rust-dev
+//! mode — this is shipped as ONE PR (add Rust + delete TS predecessor
+//! in same commit), not the 4-PR migration cadence.
+//!
+//! ## Scope
+//!
+//! - `ValidateResponseRequest` (ts-rs) — IPC request
+//! - `ValidateResponseDecision` (ts-rs) — IPC response carrying
+//!   `decision: SUBMIT | CLARIFY | SILENT`, confidence, reason, model,
+//!   timestamp
+//! - `ResponseDecision` enum (ts-rs) — three-way decision shape
+//! - `ValidateResponseError` — typed: NoAdapter, Generation
+//! - `build_validate_prompt(&request) -> String` — pure
+//! - `parse_decision(ai_text) -> ResponseDecision` — pure
+//! - `evaluate_validate_response(request) -> Result<ValidateResponseDecision, _>`
+//!   — async (calls Groq via existing registry, parses decision, stamps)
+//!
+//! ## Failure discipline
+//!
+//! - All errors typed.
+//! - parse_decision defaults to SUBMIT when AI returns unrecognized text
+//!   — matches TS behavior (the choice is "fail open: submit the draft"
+//!   rather than "fail closed: silence the persona"). Documented at the
+//!   parser; caller can compare against `decision == SUBMIT && reason
+//!   == DEFAULT_REASON_SUBMIT` if they want to detect parse-fallthrough.
+//! - No JSON parsing — model is asked for a single word, not JSON.
+//!   Different from check_redundancy.

+//! Vision description — Rust-owned multimodal inference orchestration.
+//!
+//! Pre-#1276 this lived in `system/vision/VisionInferenceProvider.ts`
+//! (176 LOC) which selected a vision-capable model, built the describe
+//! prompt, called `AIProviderDaemon.generateText`, and parsed the
+//! response. Per the oxidizer rule (Joel 2026-05-15: "if not UI/UX it
+//! is rust") all four steps belong here. The TS file becomes a thin
+//! shim that calls `Commands.execute('cognition/vision-describe', ...)`.
+//!
+//! The actual inference call delegates to the existing `ai/generate`
+//! IPC handler via `runtime::execute_json`, so the Rust adapters
+//! (Anthropic / OpenAI / LlamaCpp / etc.) handle multimodal payload
+//! shaping per their own native API contracts. This module only owns:
+//!
+//! 1. Vision-capable model selection (filter `model_registry` by
+//!    `Capability::Vision` + the registered adapter set, prefer local).
+//! 2. Prompt construction from `VisionDescribeOptions` flags.
+//! 3. Multimodal request assembly (text + base64 image content parts).
+//! 4. Response parsing into `VisionDescription`.
+//!
+//! Outlier-validation pair: codex's #1284 (AIDecisionService.evaluateGating
+//! → cognition/should-respond) is the structured-decision shape; this
+//! card is the freeform-shape. Same Rust+thin-TS-shim pattern.

+//! Consolidates the previously-parallel `concurrent/` and `concurrency/`
+//! top-level dirs into one module. Prior to this refactor:
+//!   - `concurrent/`: data structures (MessageProcessor, PriorityQueue)
+//!   - `concurrency/`: policies (ConcurrencyPolicy, TokioConcurrencyPolicy,
+//!     single-flight maps, semaphores)
+//!
+//! Two dirs with overlapping names was an architecture smell — neither
+//! was the canonical "where do concurrency mechanics live" answer. This
+//! module now is. Domain modules import from `crate::concurrency::*`.
+//!
+//! ## Module layout
+//!
+//! - `policy` — ConcurrencyPolicy trait + TokioConcurrencyPolicy impl,
+//!   single-flight per-key coordination, refcount guards (#1235).
+//!   Used by `cognition::shared_analysis` and `live::transport::livekit_agent`.
+//! - `message_processor` — Reusable `MessageProcessor` trait for
+//!   processing messages concurrently. Generic over message type.
+//! - `priority_queue` — Generic priority-based message queue.
+//!
+//! ## Submodules vs flat
+//!
+//! Files stay separate so callers reading a 200-LOC priority_queue
+//! impl don't also have to scroll past 600+ LOC of policy machinery.
+//! Re-exports here keep the public API flat at `crate::concurrency::X`.

+/// RAII refcount guard for an in-flight entry (#1232 + #1235).
+///
+/// **Every** caller — the analyzer (first caller for this key) AND each
+/// awaiter — holds a `RefCountGuard` for the duration of its
+/// `single_flight` call. The entry's `Arc<AtomicUsize>` is bumped under
+/// the in_flight mutex when the guard is constructed, and decremented
+/// when the guard drops. The map entry is removed only when the
+/// refcount hits zero (under the lock, double-checked to handle a new
+/// caller racing in between fetch_sub and the lock acquisition).
+///
+/// # Why every caller holds one (not just the analyzer)
+///
+/// Pre-#1235 only the analyzer held a Drop guard. That correctly fixed
+/// the panic-cleanup case (#1232) but left a window during analyzer
+/// cancellation:
+///
+/// ```text
+///   T0: analyzer.single_flight("k") → creates entry, holds guard
+///   T1: awaiter1.single_flight("k") → clones Shared, no guard
+///   T2: analyzer task is dropped (cancellation)
+///   T3: analyzer's guard.drop fires → removes entry from in_flight
+///   T4: NEW caller.single_flight("k") → finds no entry → starts a
+///       FRESH `work` future for "k" — duplicate work, contract
+///       violated. awaiter1 still completes the original Shared, but
+///       there are now two concurrent inferences for the same key.
+/// ```
+///
+/// With per-caller refcounts, the entry stays alive as long as ANY
+/// caller (analyzer or awaiter) is still holding the Shared. Only when
+/// the last holder drops does cleanup fire — at which point any future
+/// caller correctly starts fresh (no one is waiting for the old
+/// result).
+///
+/// # Panic behavior preserved
+///
+/// If the work future panics, the panic unwinds through `shared.await`
+/// in every caller (Shared re-raises to clones). All guards drop during
+/// unwind, refcount → 0, entry removed. Same end state as #1232.

+//! `AgentContext` — substrate citizen for external AI agents.
+//!
+//! Slice 4 of #142 generalizes the Slice-3 `ClaudeContext` into a
+//! provider-parameterized `AgentContext`. Same shape, same bootstrap
+//! contract — but `provider` carries which external AI flavor this
+//! session is (Claude, Codex, Gemini, Hermes, OpenClaw, future).
+//! Per Joel 2026-06-04: "What about Codex and Gemini etc.? Use
+//! always lowercase."
+//!
+//! ## Why provider as a `String` not a sub-enum
+//!
+//! Extensibility. Adding a new agent provider (GPT-5, Claude-5,
+//! some company's bespoke agent) should NOT require a substrate
+//! release that ships an enum variant. The few sites that branch
+//! on provider (future tool-use harness, model-tier metadata) match
+//! the string. Per the Slice-1 reviewer's IdentityKind extensibility
+//! concern.
+//!
+//! ## Bootstrap flow
+//!
+//! 1. Resolve home via the symmetric helper
+//!    `citizen_home_path(continuum_root, IdentityKind::Agent,
+//!     Some(provider), instance_label)` →
+//!    `<continuum_root>/citizens/agents/<provider>/<label>/airc/`.
+//! 2. Migration check: if the legacy path exists for `provider ==
+//!    "claude"` (`<continuum_root>/claudes/<label>/airc/`), hard-
+//!    error with an actionable `mv` command per
+//!    [[no-fallbacks-ever]].
+//! 3. `tokio::fs::create_dir_all`. Capture pre-existence of the home
+//!    BEFORE mkdir for honest resume/mint telemetry.
+//! 4. `airc_lib::Airc::attach_as(home, agent_name, daemon_socket)`.
+//! 5. Optional `Airc::join(room_name)` per the name-derives-channel
+//!    discipline (see PersonaAircRuntime's hard-won lesson +
+//!    PR #1524's review fix).
+//! 6. Construct `Identity { id: peer_id, kind: Agent, agent_name,
+//!    home_path, default_room, source, agent_provider:
+//!    Some(provider) }`.
+//! 7. Wrap `Arc<Airc>` in the shared `AircHandleAdapter`.

+//!
+//! ## Layout
+//!
+//! ```text
+//! <continuum_root>/citizens/<kind_slug>/[<provider_slug>/]<label>/airc/
+//! ```
+//!
+//! - `<continuum_root>` typically `~/.continuum`
+//! - `<kind_slug>` lowercase plural — `personas`, `agents`, `humans`,
+//!   `jtags`, `webs`
+//! - `<provider_slug>` ONLY for Agent kinds — `claude`, `codex`,
+//!   `gemini`, `hermes`, future. Always lowercase per Joel's
+//!   directive.
+//! - `<label>` the human-readable instance identifier (Maya, Niko,
+//!   instance label, host handle, jtag invocation id, tab id)
+//! - `airc/` the kind-agnostic airc subdirectory (`identity.key`,
+//!   airc state DB)
+//!
+//! ## Why this lives in `context/`
+//!
+//! The path is the surface every Context-implementing kind uses at
+//! bootstrap. Concretely: `PersonaAircRuntime`, `AgentContext`,
+//! future `JtagContext` / `HumanContext` / `WebContext` all call
+//! `citizen_home_path(...)` to resolve their on-disk home. ONE
+//! helper, one symmetry-enforcing function, called from every
+//! kind's bootstrap.

+//! `Context` — the substrate's universal actor handle, Android-Context style.
+//!
+//! Per Joel 2026-06-04: "This is like Android context and must be fixed."
+//! + [[airc-is-the-session-not-a-feature]].
+//!
+//! ## Mental model
+//!
+//! Android's `Context` is the ubiquitous handle every Android API takes.
+//! You cannot `startActivity`, `openFileInput`, `getString(R.string.X)`,
+//! `sendBroadcast`, or read a SharedPreference without one. Context
+//! carries app identity (package, signature), resources, and services.
+//!
+//! The substrate's `Context` is the same shape. It carries:
+//! - The actor's **`Identity`** (peer_id, kind, agent_name, home, room)
+//! - The actor's **airc citizen handle** — the substrate-wide
+//!   `Arc<dyn AircCitizen>` through which `say()`, `subscribe()`,
+//!   `peer_id()` are reached
+//! - (future slices) ORM scope, log scope, capture sinks
+//!
+//! Every substrate API that has substrate effect takes `&dyn Context`.
+//! Functions that don't take a `Context` are either (a) pure or (b)
+//! wrong and need fixing. There is no global airc handle, no implicit
+//! "process-wide" actor — without a `Context`, you cannot reach the
+//! substrate.
+//!
+//! ## Why a trait, not a struct
+//!
+//! Per the polymorphism doctrine in CLAUDE.md and the BaseUser
+//! hierarchy plan named in `persona/supervisor.rs:108-118`:
+//! - `PersonaContext` = `Context` + (role, profile, adapter, cognition)
+//! - `ClaudeContext` = `Context` + (tool-use harness, model tier)
+//! - `JtagContext` = `Context` + (CLI invocation args, stdio streams)
+//! - `HumanContext` = `Context` + (UI session, auth scope)
+//!
+//! Each variant extends the substrate handle with kind-specific
+//! state. The trait is the common contract; concrete types add what
+//! their kind needs.
+//!
+//! ## What this slice IS
+//!
+//! - `Context` trait with `identity()` + `airc()` accessors — the
+//!   minimum substrate-wide contract.
+//! - `PersonaContext` impls `Context` (already had the fields; just
+//!   adds the trait impl). Outlier 1 in the validation pattern.
+//! - `StubContext` for tests — maximally different from
+//!   `PersonaContext` (no cognition, no adapter). Outlier 2.
+//! - **One new substrate utility** (`log_actor_action`) that takes
+//!   `&dyn Context` — proves the trait is load-bearing, not theoretical,
+//!   per the CLAUDE.md outlier-validation pattern.
+//!
+//! ## What this slice is NOT
+//!
+//! - `ClaudeContext` / `JtagContext` / `HumanContext` concrete types
+//!   (Slice 3, with bootstrap paths)
+//! - `&dyn Context` ubiquitous across substrate APIs (Slice 4)
+//! - PersonaInstanceInfo → Identity migration in the persona module

+/// The substrate's universal actor handle.
+///
+/// Every substrate API that produces substrate-visible effect takes
+/// `&dyn Context`. Implementors are: `PersonaContext` (today),
+/// `ClaudeContext` / `JtagContext` / `HumanContext` (Slice 3),
+/// `StubContext` (tests + benchmarks).
+///
+/// ### Bounds
+///
+/// `Send + Sync + 'static` so trait objects can be stored in
+/// long-lived registries (session tables, capture sinks, work-card
+/// claim records) — Slice 4 will surface this need; adding `'static`
+/// now while the trait has zero downstream consumers is cheap.
+/// Concrete implementors (`PersonaContext`, `StubContext`, the
+/// upcoming `ClaudeContext` / `JtagContext` / `HumanContext`) are
+/// all `'static` by construction.
+///
+/// ### Why methods return what they return
+///
+/// - `identity()` returns `Cow<'_, Identity>` — implementors that
+///   already store an `Identity` (StubContext today; PersonaContext
+///   post-Slice-1B; ClaudeContext / JtagContext from birth) return
+///   `Cow::Borrowed(&self.identity)` at zero cost. Transitional
+///   implementors that have to synthesize from older state
+///   (PersonaContext's current `PersonaInstanceInfo`-backed impl)
+///   return `Cow::Owned(synthesized)`. Same caller ergonomics via
+///   `cow.as_ref()`; no clone tax baked into the steady-state.
+/// - `airc()` returns `&Arc<dyn AircCitizen>` — every implementor
+///   already holds the citizen as `Arc<dyn AircCitizen>` (per
+///   `[[personas-are-citizens-airc-is-identity-provider]]`), so
+///   borrowing is free.
+pub trait Context: Send + Sync + 'static {
+    /// The actor's identity — peer_id (== `id`), kind, name, home,
+    /// default room, source. `Cow` lets storing implementors borrow
+    /// for free; transitional synthesizing implementors return
+    /// `Cow::Owned`.
+    fn identity(&self) -> Cow<'_, Identity>;
+
+    /// The actor's live airc citizen handle. Substrate primitives
+    /// that need to `say()`, `subscribe()`, get `peer_id()`, or
+    /// otherwise interact with the grid reach them through this.
+    fn airc(&self) -> &Arc<dyn AircCitizen>;
+}
+
+/// Substrate utility: emit a structured log line scoped to a
+/// specific actor. The first proven `&dyn Context` consumer —
+/// validates the trait is load-bearing, not theoretical, per the
+/// CLAUDE.md outlier-validation pattern.
+///
+/// Why this lives in `context/`: every substrate-wide concern that
+/// needs an actor's identity ("who did this") routes through
+/// `&dyn Context`. Logging is the first such concern; capture
+/// scoping, ORM-tenancy, and rate-limit attribution will follow in
+/// the same shape (each adding a method on `Context` or a free
+/// function alongside this one).
+pub fn log_actor_action(ctx: &dyn Context, action: &str) {
+    let id = ctx.identity();
+    let id = id.as_ref();
+    tracing::info!(
+        actor.id = %id.id,

+        "actor action"
+    );
+}
+
+// ─── Test fixture: StubContext ──────────────────────────────────────────
+
+/// A `Context` implementor for tests — holds an `Identity` + a
+/// stub airc citizen. Per `[[test-fixtures-are-system-primitives]]`
+/// every test that needs a `&dyn Context` leases THIS rather than
+/// inventing a bespoke variant.
+///
+/// Outlier-validation status (CLAUDE.md discipline): `Context` is
+/// now validated across:
+/// - `PersonaContext` (persona kind, transitional synthesizes from
+///   `PersonaInstanceInfo`, returns `Cow::Owned`)
+/// - `AgentContext` (Slice 4, non-persona kind, parameterized by
+///   provider so Claude/Codex/Gemini/Hermes/future all flow through
+///   ONE shape, stores Identity directly, returns `Cow::Borrowed`)
+/// - `StubContext` (test fixture, stores Identity, returns
+///   `Cow::Borrowed`)
+/// Three impls with different storage shapes and Cow semantics all
+/// satisfy the trait without forcing — the interface is validated.
+/// Future variants (HumanContext, JtagContext, WebContext) slot
+/// into the same shape.
+///
+/// `pub` (not `#[cfg(test)]`) so production code that wants a
+/// no-substrate-effect Context for benchmarks or replay can use it
+/// too. Stub adapters are first-class in the substrate per
+/// `[[inference-is-an-adapter-always-in-the-loop]]`; stub Contexts

+//! Roadmap item L1-6 (see docs/grid/GRID-MIGRATION-ROADMAP.md).
+//! Spec: GRID-BUS-ARCHITECTURE §4.4 + MULTI-PEER-COMMANDS §7.
+//!
+//! Every contract event on the wire is a `SignedContractEvent<P>` where
+//! `P` is one of the 8 payload types from `event_classes.rs`. The
+//! envelope carries:
+//!   - `event_name`: which class (`contract:proposed`, etc.) — pinned
+//!     into the signed bytes so an envelope can't be relabeled.
+//!   - `payload`: the typed event-specific fields.
+//!   - `signer_pubkey`: the 32-byte ed25519 public key (hex-encoded on
+//!     the wire). Verifies the signature.
+//!   - `signature`: 64-byte ed25519 signature (hex-encoded on the wire)
+//!     over `canonical_hash(event_name, payload)`.
+//!   - `signed_at_unix_ms`: signer's wall-clock at sign time (audit-only;
+//!     replay does NOT consult clock skew between peers).
+//!
+//! The signed bytes pin `event_name` + `payload` together so a
+//! malicious replay can't take a valid `bid` signature and present it
+//! as a `proposed`. The envelope itself carries the signature; verify
+//! recomputes the canonical hash from `(event_name, payload)` and
+//! checks against the signer's pubkey.

+//! The 8 contract event class names + their payload types.
+//!
+//! Roadmap item L1-6 (see docs/grid/GRID-MIGRATION-ROADMAP.md).
+//! Spec: GRID-BUS-ARCHITECTURE §4.4 + MULTI-PEER-COMMANDS §7.
+//!
+//! These are the on-the-wire event class names that `declare_contract_event_classes`
+//! registers with the L1-1 `EventClassRegistry` at startup. Once declared,
+//! `Events.emit('contract:proposed', payload)` (TS side) or
+//! `event_class_registry().resolve_channel('contract:proposed', payload)`
+//! (Rust side) route the event onto the appropriate airc channel.
+//!
+//! ## Chain shape
+//!
+//! ```text
+//!   contract:proposed   — proposer publishes terms + signs
+//!         │
+//!         ▼
+//!   contract:bid        — interested executor publishes their bid, signs
+//!         │
+//!         ▼
+//!   contract:accepted   — proposer picks one bid, signs the acceptance
+//!         │
+//!         ▼
+//!   contract:executing  — executor signs "started work" (optional, observability)
+//!         │
+//!         ▼
+//!   contract:delivered  — executor signs the delivered artifact + alloy_hash
+//!         │
+//!         ▼
+//!   contract:verified   — proposer (or auditor) signs verification result
+//!         │
+//!         ▼
+//!   contract:paid       — payer signs the settlement (zero-LP household = OK)
+//!         │
+//!         ▼ (only when a participant disputes)
+//!   contract:disputed   — any signer can file with reason + sig
+//! ```
+//!
+//! Every event carries the same `contract_id` so the airc cursor replay
+//! can stitch the chain together from a single-channel scan.

+//! L1-6 contract event chain + ed25519 signing.
+//!
+//! Roadmap item L1-6 (see docs/grid/GRID-MIGRATION-ROADMAP.md).
+//! Spec: GRID-BUS-ARCHITECTURE §4.4 + MULTI-PEER-COMMANDS §7.
+//!
+//! Three layers, native-truth-thin-SDK pattern:
+//!
+//!   1. `signing` — ed25519 primitives (matches `airc-protocol = "2"`).
+//!      Keypair generation, sign, verify, canonical SHA-256 hashing.
+//!   2. `event_classes` — the 8 contract event class names + payloads,
+//!      plus `declare_contract_event_classes()` that registers them
+//!      with the L1-1 `EventClassRegistry`.
+//!   3. `envelope` — the `SignedContractEvent<P>` wrapper that pairs
+//!      a typed payload with `event_name` + `signer_pubkey_hex` +
+//!      `signature_hex`. Signature pins `(event_name, payload)`
+//!      together so relabeling attacks fail verification.
+//!
+//! Phase A: primitives + types + declarations + unit tests.
+//! Phase B: pubkey lookup against L1-4's `presence:peer-manifest`,
+//! verify-on-replay handler over L1-2's `AircEventTransport`.

+//!
+//! Scope (Phase A — buildable independent of L1-4):
+//!   - Key types: `ContractSigningKey` (private), `ContractVerifyingKey` (public).
+//!   - `sign(payload_bytes)` / `verify(payload_bytes, sig, pubkey)`.
+//!   - `canonical_hash(payload)`: SHA-256 of the canonicalized payload
+//!     bytes — the deterministic substance the signature commits to.
+//!   - Errors are explicit (`SigningError`); no silent fail-soft paths.
+//!
+//! Phase B (deferred to a follow-up PR once L1-4 lands):
+//!   - Pubkey lookup against the per-peer manifest index.
+//!   - Verify-on-replay handler that pulls pubkeys at event-receipt time.

+//! ForgeArtifact — foundry-generated output for a recipe.
+//!
+//! Per the design at docs/architecture/FORGE-RECIPE-AS-ENTITY.md.
+//! The artifact is what the foundry emits AFTER consuming a `ForgeRecipe`
+//! and running its stages. It carries the recipe lineage (so you can
+//! always answer "which recipe produced this?") plus everything the
+//! foundry measured during the run that no human could have known
+//! beforehand: benchmark results, hardware-verified device list, alloy
+//! content hash, publication receipt, integrity attestation.
+//!
+//! The artifact is what `publish_model.py` reads. The recipe is what
+//! a human authors. The foundry is the function recipe → artifact.
+//!
+//! # What this PR ships (Phase 1a of #1164)
+//!
+//! - `ForgeArtifact` Rust value type with ts-rs bindings + tests
+//! - Recipe lineage fields (`recipe_id`, `recipe_version`, `forged_at_ms`)
+//! - Result fields kept opaque (`serde_json::Value`) for v1 — Phase 2
+//!   types `AlloyResults`, `AlloyReceipt`, `IntegrityAttestation` as
+//!   first-class Rust structs once the foundry executor lands and
+//!   needs them.
+//!
+//! # Naming (consensus position #1)
+//!
+//! "ForgeAlloy" → "ForgeArtifact" rename happens in **Phase 1b** (TS
+//! side, 15 file references; separate slice). This Rust file ships
+//! with the new name from day 1.

+//! ForgeRecipe — authored input for the foundry pipeline.
+//!
+//! Per the design at docs/architecture/FORGE-RECIPE-AS-ENTITY.md
+//! (continuum#1164/#1165). The recipe captures everything a human
+//! decides BEFORE running the foundry: prose fields, source model,
+//! pipeline stages with notes, calibration corpus, quant tiers,
+//! evaluation benchmarks, prior baselines, hardware target. The
+//! foundry consumes a recipe + execution results and emits a
+//! `ForgeArtifact` (see sibling `artifact.rs`).
+//!
+//! # What this PR ships (Phase 1a of #1164)
+//!
+//! - Pure Rust value types for ForgeRecipe + supporting structs
+//! - ts-rs bindings to `protocol/typescript/forge/`
+//! - Serde roundtrip + ts-rs export tests
+//!
+//! # Deferred to later phases
+//!
+//! - **Phase 1b:** rename existing TS-side `ForgeAlloy` → `ForgeArtifact`
+//!   (15 TS files reference the old name; separate slice).
+//! - **Phase 2:** typed `RecipeStage` enum matching the existing
+//!   `AlloyStage` discriminated union from forge-alloy/python/forge_alloy/types.py
+//!   (ports the stage zoo into Rust as the source of truth). v1 carries
+//!   stages as `Vec<serde_json::Value>` so the recipe is usable today.
+//! - **Phase 2:** typed `AlloyResults`, `AlloyReceipt`, `IntegrityAttestation`
+//!   on the artifact side.
+//! - **Phase 3:** entity registry registration + `data/*` collection wiring
+//!   (the recipe types ship first; storage hooks them up next).
+//!
+//! # Conventions (matching existing persona/* modules)
+//!
+//! - `Uuid` fields use `#[ts(type = "string")]` for the TS export.
+//! - Strings + bools + numbers map directly via ts-rs defaults.
+//! - Nested types that aren't yet in Rust use `serde_json::Value` with
+//!   `#[ts(type = "unknown")]` so the TS side gets `unknown` (caller
+//!   must validate via the existing Python pydantic schemas until
+//!   Phase 2 ports the types).

+//! Artifact-key constants + bus publishing helpers for genome
+//! events. PR-4 of working-set-manager.
+//!
+//! Background: PR-1 (#1346) shipped the typed `PageFault`,
+//! `EvictionRecord`, and `AccessDenied` events. PR-2 (#1353) named
+//! them on the trait surface. PR-3 (#1355) impl returns them through
+//! its `Result` arms (PageFault) and direct method returns
+//! (AccessDenied). What's been missing is the wire — what
+//! ArtifactKey + payload shape downstream subscribers (audit-recorder
+//! #1344, sentinel-observer, demand-aligned-recall) bind to.
+//!
+//! This module fills that gap with three building blocks:
+//!
+//! 1. **Canonical `ArtifactKey` constants** — every genome event has
+//!    one stable key. Subscribers refer to the constant, not a string
+//!    literal, so the wire stays consistent across renames.
+//!
+//! 2. **Publishing helpers** — `publish_page_fault`, etc. Each takes
+//!    the bus + registry + the typed event, serializes the payload,
+//!    and publishes through the artifact dispatch path I shipped in
+//!    #1339 + #1343. Callers don't construct keys / serialize / route
+//!    by hand.
+//!
+//! 3. **Subscriber convenience** — `subscribe_to_genome_events` wires
+//!    a module to all three keys at once via `bus.subscribe_artifact`
+//!    (the path #1343 added).
+//!
+//! ## What PR-4 does NOT do (PR-5)
+//!
+//! Wiring the helpers INTO `LocalWorkingSetManager` so its
+//! `page_in`/`page_out`/`audit_access` auto-publish after each call.
+//! That decorator/extension lands in PR-5. PR-4 ships the wire
+//! definitions + helpers so that PR-5 only needs to plumb the bus +
+//! registry references; the keys + payloads are already canonical.
+//!
+//! Why split: the wire shape is the coordination point with codex's
+//! audit-recorder (#1344, subscribes to `AccessDenied`) + sentinel-
+//! observer (subscribes to `PageFault`). Naming the keys + publishing
+//! helpers in their own PR locks the contract first, lets downstream
+//! subscribers wire to it BEFORE the LocalWorkingSetManager
+//! integration (PR-5) plumbs them in.

+//! `LocalWorkingSetManager` — per-process implementation of the
+//! `WorkingSetManager` trait shipped in PR-2 (#1353).
+//!
+//! Holds:
+//! - `Vec<Box<dyn TierStore>>` — the tier chain, ordered Fast → Frozen
+//! - `RwLock<HashMap<PersonaId, WorkingSet>>` — per-persona working sets
+//! - `RwLock<HashMap<PageRef, PersonaId>>` — page-ownership map for
+//!   the MMU-style `audit_access` enforcement
+//!
+//! Page-in walks the tier chain from highest (Fast) to lowest (Frozen),
+//! returns the first hit, optionally promotes the page to the working
+//! set's preferred tier. A miss with no resident copy is a true cold
+//! miss → `PageFault::from_role: None`.
+//!
+//! ## What PR-3 ships
+//!
+//! - Pure local implementation. No bus publishing baked in (the
+//!   `page_in` Result already carries `PageFault` as the typed
+//!   observability signal; callers wire to the artifact dispatch
+//!   path #1339+#1343 themselves).
+//! - The four trait methods: `page_in`, `page_out`, `working_set`,
+//!   `audit_access`.
+//! - Constructor that registers tier stores + capacity per persona.
+//! - Tests using a stub `TierStore` that records calls so the test
+//!   can assert which tier was queried + that PageFault carries the
+//!   right `from_role` / `to_role`.
+//!
+//! ## What PR-3 does NOT ship (PR-4 or later)
+//!
+//! - Eviction policy invocation when the target tier is at limit —
+//!   PR-3 returns `TierError::NoEvictionCandidate` instead of running
+//!   the policy. Policy invocation is a tier-store-internal concern
+//!   that the PR-3 impl doesn't drive; PR-4's enhancement is a wired
+//!   callback so the manager observes and re-publishes the
+//!   `EvictionRecord` that the tier returned.
+//! - Pinning logic for composition-layer page pinning — that's part
+//!   of PR-3 of demand-aligned-recall (composer cache).
+//! - The `check_permission(actor, region, op)` method from PR-2's
+//!   "deliberately deferred" list. Lands in PR-4 alongside the
+//!   GenomeRegion + Op type definitions.

+//! `WorkingSetManager` trait — the top-level paging interface every
+//! persona's cognition path calls. Per GENOME-FOUNDRY-SENTINEL Parts
+//! 3 (paging) and 4 (compartmentalization).
+//!
+//! PR-2 of working-set-manager ships the **trait surface only**. The
+//! per-persona implementation that holds the `Box<dyn TierStore>`
+//! per role, services `page_in` by walking the tier chain, and
+//! publishes `PageFault` / `EvictionRecord` events through the
+//! artifact dispatch path (#1339+#1343) lands in PR-3.
+//!
+//! ## What the trait promises
+//!
+//! - `page_in` — promote a page into the persona's working set. May
+//!   trigger eviction. On miss-with-no-eviction-candidate returns
+//!   `PageFault` (used by sentinel to learn the persona's access
+//!   pattern), not a generic error.
+//! - `page_out` — demote a page out of the working set toward a
+//!   named tier role. Used by the eviction policy + composition layer
+//!   when it's done with a page.
+//! - `working_set` — read-only snapshot of the persona's current
+//!   resident pages. The hot path uses this to decide "do I need to
+//!   page in or is it already there." Returns `&WorkingSet` (no
+//!   clone) because the call is hot.
+//! - `audit_access` — MMU-style permission check. Returns
+//!   `AccessDenied` if the page is private to another persona. This
+//!   is one of the four typed events audit-recorder (#1344)
+//!   subscribes to.
+//!
+//! ## What's deliberately deferred
+//!
+//! `check_permission(actor, region, op)` from GENOME-FOUNDRY-
+//! SENTINEL Part 4 lands in PR-3 alongside the GenomeRegion + Op
+//! type definitions and the per-region permission matrix. PR-2 only
+//! ships the four methods that don't need those types — keeping
+//! the surface tight so this PR is reviewable on its own.

+//! Genome — the substrate's cache hierarchy and paging data layer.
+//!
+//! The cache is a sequence of **tier roles** parameterized by hardware
+//! class. Discrete-GPU hardware has five distinct tiers; unified-memory
+//! hardware collapses the top two into one (Warm is omitted). The Rust
+//! code is identical across hardware; only the `Vec<TierConfig>`
+//! per-policy differs.
+//!
+//! PR-1 of working-set-manager (per MODULE-CATALOG §VII +
+//! GENOME-FOUNDRY-SENTINEL Parts 2/3/4) ships the **data layer only**:
+//! the typed surface that downstream PRs (trait + impl + dispatch
+//! wiring) will hang behaviors on. No I/O, no async, no traits — just
+//! the structs/enums + ts-rs exports + serde + a small unit-test pin
+//! for each invariant the type system guarantees.
+//!
+//! This mirrors the shape that worked for CBAR-PIECE-2 PR-1 (#1321 —
+//! ArtifactKey/Selector/Cadence types) + PIECE-5 PR-1 (#1331 — gate
+//! types): land the data shape first, hang behaviors on it incrementally
+//! across later PRs. Each subsequent PR is reviewable independently.
+//!
+//! ## PR-1 scope (this PR)
+//!
+//! - `TierRole` — Fast / Warm (discrete-GPU-only) / Bench / Cold / Frozen
+//! - `EvictionPolicy` — per-role policy enum
+//! - `TierCapacity` — current_used + configured_limit, both bytes
+//! - `EvictionRecord` — typed event emitted when a page is evicted
+//! - `PageKind` — LoRALayer / MoEExpert / KVCache / Engram
+//! - `PageOffset` — sub-artifact offset (for MoE experts, KV chunks)
+//! - `PageRef` — fully-qualified page address (kind + artifact + offset)
+//! - `ResidentPage` — a page currently in some persona's working set
+//! - `WorkingSetCapacity` — per-persona budget the governor sets
+//! - `WorkingSet` — a persona's currently-resident pages
+//! - `PageFault` — typed event when a page must be paged in
+//! - `AccessDenied` — typed refusal from the MMU-style permission check
+//!
+//! ## PR-1 scope (NOT this PR — explicitly deferred)
+//!
+//! - `WorkingSetManager` trait — PR-2 of this stack
+//! - `TierStore` trait + role-specific impls (5 of them) — separate PR set
+//! - MMU permission table enforcement — PR-2 or PR-3 of this stack
+//! - Wiring `PageFault` / `EvictionRecord` to the trace bus via my
+//!   just-shipped artifact dispatch (#1339 + #1343) — PR-3 of this stack
+//! - Hardware-anchor `Vec<TierConfig>` from the governor — separate PR
+//!   (substrate-governor lane, codex's territory if they want it)
+//!
+//! ## Why types-only first
+//!
+//! Two reasons that compound:
+//!
+//! 1. **Compiler-enforced contract.** Naming a `TierRole` enum makes
+//!    "L1→L2 eviction on UMA" structurally impossible because there is
+//!    no `Warm` tier to evict to. The type system removes the need for
+//!    runtime checks. Get the names right before the behaviors land.
+//!
+//! 2. **Multi-author shipping.** Codex + I are racing the MODULE-CATALOG
+//!    queue. Naming the types first locks the seam every downstream PR
+//!    builds against — codex's threat-detector + my working-set-manager
+//!    impl + the next persona-cognition slice all subscribe to the same
+//!    `PageFault` / `AccessDenied` shapes. PR-1's types are the
+//!    coordination substrate.

+//! `demand-aligned-recall` — PR-1: typed data layer for the
+//! substrate's most-used primitive. Per GENOME-FOUNDRY-SENTINEL
+//! Part 7.
+//!
+//! Recall is the lookup every persona's cognition reaches for:
+//! "give me a ranked pool of artifacts I can compose from to handle
+//! this task." It spans local cache (Fast/Bench/Cold/Frozen) → grid
+//! peers → federation pulls. The scoring incorporates semantic
+//! similarity, outcome history, recency, tier proximity, and
+//! provenance trust — but the **load-bearing** type is `ResidencyHint`
+//! per the spec: "the persona doesn't just see *what's relevant*, it
+//! sees *where it lives* and *what it costs to use*."
+//!
+//! PR-1 of demand-aligned-recall ships the typed data surface only.
+//! No trait impl, no scoring function, no grid-peer calls — those
+//! land in PR-2 (trait surface) and PR-3 (LocalDemandAlignedRecall
+//! impl with the scoring function + working-set integration).
+//!
+//! ## What PR-1 ships
+//!
+//! - `ResidencyHint` — the load-bearing type with four variants
+//!   (Hot/Local/GridPeer/NotResident), tied to the genome `TierRole`
+//!   from PR-1 of working-set-manager (#1346).
+//! - `RecallScore` — composite score struct with the five factors
+//!   the scoring function combines.
+//! - `RecallScope` — Local / LocalThenGrid { max_grid_pulls } /
+//!   Federation { peers, max_latency_ms }. Bounds what the recall
+//!   may touch.
+//! - `FreshnessTarget` — BestEffort / FreshAsOf { ts_ms } / Strict.
+//! - `TaskKind` — the seven canonical task kinds the substrate
+//!   names: Chat / Code / Vision / ToolUse / Memory / Plan / Other.
+//! - `TrustClass` — Local / TrustedPeer / KnownPeer / Anonymous.
+//! - `PeerId(Uuid)` — typed wrapper distinct from PersonaId /
+//!   ArtifactId (same primitive, different type — type system
+//!   catches swapped arguments).
+//! - `RecallError` — typed errors covering Budget exhaustion, Scope
+//!   denial, FreshnessUnmet, and federation-level NoMatchingArtifacts.
+//!
+//! ## What PR-1 does NOT ship (PR-2 / PR-3)
+//!
+//! - `DemandAlignedRecall` trait — PR-2
+//! - `CapabilityQuery`, `RecallContext`, `RankedPool`,
+//!   `RecallScoreWeights` full shapes — PR-2 (they reference PR-1's
+//!   types but depend on RecallContext + composition types that
+//!   benefit from being grouped with the trait)
+//! - Scoring function + grid_penalty + recency_decay — PR-3
+//! - `LocalDemandAlignedRecall` impl + working-set integration — PR-3
+//! - `RecallTrace` + replay determinism — PR-3
+//! - Embedding model integration — separate Lane H slice

+/// The scoring function (PR-3) combines this with semantic match
+/// and outcome history; the persona can also read the hint directly
+/// when it wants to make an explicit cost trade-off (e.g. "stay
+/// local even if a slightly higher-scoring layer is on a grid peer").
+///
+/// Variants:
+/// - `Hot { role }` — already in this persona's working set at the
+///   given tier role (typically Fast, or Warm on discrete-GPU
+///   hardware). Cheapest to use.
+/// - `Local { role }` — on this machine but not in this persona's
+///   working set; promotable from Bench/Cold/Frozen via the
+///   working-set-manager's page_in (#1355).
+/// - `GridPeer { peer, est_latency_ms }` — resident on a federated
+///   peer; would require a network pull to use.

+///   on any peer the persona has visibility into; would require
+///   the foundry to import or sentinel to refine. Cost is "indefinite

+//! `demand-aligned-recall` PR-3b: `LocalDemandAlignedRecall` —
+//! the per-process implementation that composes PR-3a's scoring
+//! function (`recall_scoring::score`) with a candidate-injection
+//! API to produce ranked `RankedPool`s.
+//!
+//! PR-3b ships the ranking engine but NOT the candidate-source
+//! integration. The recall walks whatever the caller hands it; the
+//! caller (PR-3c's working-set + genome-catalog walker) is
+//! responsible for sourcing candidates from the substrate.
+//!
+//! Why split: PR-3b stays a small atomic slice (~250 LoC) reviewable
+//! as pure ranking logic. PR-3c adds the integration with
+//! `WorkingSetManager` (from #1355) + the genome catalog (future)
+//! and wires `LocalDemandAlignedRecall` into Runtime as the
+//! substrate's recall provider.
+//!
+//! ## What PR-3b ships
+//!
+//! - `CandidateArtifact` — a fully-described candidate ready for
+//!   scoring. Carries the per-factor inputs (semantic, outcome,
+//!   provenance) + residency + last-used timestamp. PR-3c populates
+//!   from substrate sources; PR-3b tests construct directly.
+//! - `LocalDemandAlignedRecall { weights, half_life_ms }` — the
+//!   ranking engine. Holds the governor-tunable scoring weights +
+//!   recency half-life. Thread-safe (the ranking is pure-function
+//!   over the candidate set).
+//! - `rank(now_ms, candidates)` method — scores every candidate,
+//!   partitions by `PageKind` into the three sub-pools (layers /
+//!   experts / engrams), sorts each descending by `combined`,
+//!   returns the populated `RankedPool`.
+//! - Honors `CapabilityQuery::must_include` hard pins — the caller
+//!   filters/injects must-include candidates upstream; the rank
+//!   layer doesn't drop them.
+//!
+//! ## What PR-3b does NOT ship (PR-3c)
+//!
+//! - `DemandAlignedRecall` trait impl — needs the working-set +
+//!   genome catalog to source candidates. PR-3c wires it.
+//! - `RecallTrace` replay backing store — separate sentinel PR.
+//! - Federation candidate sourcing (RecallScope::Federation /
+//!   LocalThenGrid) — PR-3c.
+//! - Embedding model integration (the semantic factor input) —
+//!   separate Lane H slice.

+//! `demand-aligned-recall` PR-3a: scoring function + helpers.
+//! Per GENOME-FOUNDRY-SENTINEL Part 7 "The Scoring Function —
+//! Explicit, Tunable, Sentinel-Refined."
+//!
+//! Pure math, no I/O, no async. The caller (PR-3b's
+//! `LocalDemandAlignedRecall`) computes individual factors using
+//! its sources (embedding model for semantic similarity, sentinel
+//! lookups for outcome_history, trust registry for
+//! provenance_trust) and passes them as primitives. This module
+//! combines them through the weighted-sum scoring function +
+//! provides the per-factor curves the spec names:
+//!
+//! - `grid_penalty(latency_ms)` — federation peer cost curve
+//! - `recency_decay(last_used_ms, now_ms, half_life_ms)` — temporal
+//!   decay
+//! - `local_role_score(role)` — Fast=1.0 / Bench=0.6 / Cold=0.3 /
+//!   Frozen=0.1 per the spec
+//! - `tier_proximity_for(&ResidencyHint)` — dispatches by hint
+//!   variant: Hot→1.0, Local→local_role_score, GridPeer→
+//!   grid_penalty, NotResident→0.0
+//! - `score(...)` — combines the five factors with weights
+//!
+//! ## What PR-3a does NOT ship (PR-3b)
+//!
+//! - `ArtifactCandidate` struct + embedding interface — PR-3b
+//! - Cosine similarity helper — PR-3b (it depends on whatever
+//!   embedding representation lands; PR-3a keeps the math agnostic)
+//! - `outcome_window_score` over an `OutcomeWindow` — PR-3b
+//! - `trust_score` over `Provenance` + overrides — PR-3b
+//! - `LocalDemandAlignedRecall` impl — PR-3b
+//! - Working-set integration via #1362's bus hook — PR-3b

+///
+/// Inputs:
+/// - `semantic` — cosine similarity between query embedding and
+///   artifact metadata embedding. Caller computes; PR-3a doesn't
+///   depend on the embedding representation.
+/// - `outcome_history` — score from `outcome_window_score` (PR-3b);
+///   how well this artifact has performed for this persona on
+///   similar past tasks.
+/// - `last_used_ms` + `now_ms` + `half_life_ms` — feed
+///   `recency_decay`. Caller passes `DEFAULT_RECENCY_HALF_LIFE_MS`
+///   if the governor hasn't overridden.
+/// - `residency` — `ResidencyHint` from the recall walk; feeds
+///   `tier_proximity_for`.
+/// - `provenance_trust` — score from `trust_score` (PR-3b); how
+///   much the persona trusts this artifact's provenance chain.
+/// - `weights` — governor-tunable weights; sum-to-1.0 invariant
+///   already enforced by `RecallScoreWeights::new` (PR-2).
+///
+/// Returns the populated `RecallScore` with all five factors + the
+/// combined weighted sum. Bounded `[0.0, sum(weights)]` because
+/// each factor is bounded `[0.0, 1.0]` (this is true by
+/// construction: semantic + outcome_history + provenance_trust are
+/// the caller's responsibility to bound; recency_decay +
+/// tier_proximity_for are bounded by their per-factor curves).
+///
+/// The combined score is NOT clamped — if a caller passes a
+/// factor outside `[0.0, 1.0]` the combined will reflect that
+/// (debugging hook: easier to spot bad inputs than to silently
+/// clamp them). Per Joel's "never swallow errors": loud trumps

+//! `demand-aligned-recall` PR-3e: `CompositeCandidateSource` —
+//! combines multiple `CandidateSource` impls into one, with
+//! optional deduplication by artifact id.
+//!
+//! The recall stack today has one `CandidateSource` impl
+//! (`WorkingSetCandidateSource` from PR-3d). The next several PRs
+//! will add more — genome catalog walker (Bench/Cold/Frozen tier
+//! sources), federation peer source, must-include resolver. Each
+//! could re-wire `LocalDemandAlignedRecall`, but the cleaner path
+//! is a composite that combines them — recall holds ONE composite
+//! source that fans out + merges.
+//!
+//! PR-3e ships the composite. No new substrate sources yet; just
+//! the combinator. Future PRs add sources by constructing the
+//! composite with them.
+//!
+//! ## What PR-3e ships
+//!
+//! - `CompositeCandidateSource { sources, dedup }` — holds a Vec
+//!   of `Arc<dyn CandidateSource>` and a dedup policy
+//! - `DedupPolicy::None` — return all candidates from all sources
+//!   (a single artifact may appear N times if N sources surface it)
+//! - `DedupPolicy::ByArtifactId` — keep first occurrence per
+//!   `(kind, artifact_id)` tuple; later occurrences dropped
+//! - `CandidateSource::fetch` impl fans out to all sources
+//!   concurrently via `futures::future::join_all`, merges the
+//!   results, applies the dedup policy
+//!
+//! ## What PR-3e does NOT ship
+//!
+//! - Source priority ordering — `DedupPolicy::ByArtifactId` keeps
+//!   the FIRST hit in source order. A future PR may add weighted
+//!   merging or per-source priority.
+//! - Per-source error isolation — `fetch` doesn't return errors;
+//!   the underlying CandidateSource trait method returns `Vec`
+//!   (not `Result<Vec>`). Future PRs may widen the trait.
+//! - Concurrent fan-out with bounded parallelism — `join_all`
+//!   fans out unbounded. Acceptable for the current ≤5 sources;
+//!   may need bounding when federation peer counts grow.

+//! `demand-aligned-recall` PR-3f: `MustIncludeCandidateSource` —
+//! resolves `CapabilityQuery::must_include` hard pins into
+//! candidates.
+//!
+//! Per GENOME-FOUNDRY-SENTINEL Part 7: "Hard pins — recall MUST
+//! include these in the RankedPool even if their score is low. Used
+//! for persona-private LoRA layers and sticky engrams."
+//!
+//! This source ensures every entry in `query.must_include` shows up
+//! as a CandidateArtifact, even if no other source surfaces it. The
+//! composite pattern (PR-3e) handles deduplication: when wired AFTER
+//! a resident source like WorkingSetCandidateSource with
+//! ByArtifactId dedup, must-include items that ARE resident get the
+//! resident source's Hot residency + factor data; must-include
+//! items NOT resident get this source's NotResident placeholder
+//! (still ranked, just lower combined score).
+//!
+//! ## What PR-3f ships
+//!
+//! - `MustIncludeCandidateSource` (zero-state singleton — no Arc
+//!   state needed; the source is pure-function over the query)
+//! - `CandidateSource::fetch` impl that:
+//!   - reads `query.must_include` Vec<ArtifactRef>
+//!   - maps each variant (LoRALayer / MoEExpert / Engram) to a
+//!     CandidateArtifact with the appropriate `PageKind`
+//!   - marks every must-include candidate as `ResidencyHint::
+//!     NotResident { acquirable_from: SentinelRefinement }` —
+//!     placeholder; if working set has a Hot version it wins via
+//!     dedup
+//!   - uses `NEUTRAL_FACTOR_STUB` (0.5) for the three non-tier
+//!     factors, same as WorkingSetCandidateSource (PR-3d)
+//!
+//! ## Composition pattern
+//!
+//! Recommended wiring for production recall:
+//!
+//! ```ignore
+//! let composite = CompositeCandidateSource::with_default_dedup(vec![
+//!     Arc::new(WorkingSetCandidateSource::new(mgr)),     // Hot pages first
+//!     Arc::new(MustIncludeCandidateSource),              // Pins second
+//!     // future: catalog walker, federation source
+//! ]);
+//! ```
+//!
+//! With this ordering + `DedupPolicy::ByArtifactId`:
+//! - Hot resident pages keep their tier_proximity=1.0 score
+//! - Non-resident must-includes get added at tier_proximity=0.0
+//!   but still appear in the RankedPool (per the spec's hard-pin
+//!   contract)
+//! - The ranking surfaces hot stuff at the top + pinned-but-cold
+//!   stuff at the bottom of each sub-pool, which matches what
+//!   composition expects.

+//! `demand-aligned-recall` PR-3d: `WorkingSetCandidateSource` —
+//! the `CandidateSource` impl that translates a persona's
+//! `WorkingSet` (from `LocalWorkingSetManager` #1355) into recall
+//! candidates.
+//!
+//! This is the architectural payoff of the genome stack: a
+//! persona's `page_in` calls populate the working set; recall
+//! reads that same working set to surface "what's already hot"
+//! candidates ranked by `LocalDemandAlignedRecall` (#1372 + #1374).
+//! The bus hook from #1362 publishes PageFault events; this
+//! source reads the resulting WorkingSet state.
+//!
+//! ## What PR-3d ships
+//!
+//! - `WorkingSetCandidateSource` struct holding
+//!   `Arc<LocalWorkingSetManager>`
+//! - `CandidateSource::fetch` impl that:
+//!   - reads the persona's working_set_snapshot
+//!   - translates each ResidentPage into a CandidateArtifact with
+//!     `ResidencyHint::Hot { role }` (resident = hot by definition)
+//!   - filters by `query.scope` (Local → return all hot;
+//!     LocalThenGrid / Federation → also hot but mark grid sourcing
+//!     for upstream to extend)
+//!
+//! ## What PR-3d does NOT ship
+//!
+//! - Genome catalog walker (Bench/Cold/Frozen tier sources) — needs
+//!   the catalog module which doesn't exist yet
+//! - Federation peer source — needs the federation registry
+//! - Embedding integration (semantic factor) — stubs return 0.5
+//! - Sentinel outcome history lookup (outcome_history factor) —
+//!   stubs return 0.5
+//! - Trust registry lookup (provenance_trust factor) — stubs
+//!   return 0.5
+//!
+//! Each of the three "stub 0.5" factors is documented in the
+//! translation function with a TODO so the dedicated integrations
+//! can find them. Recall still ranks correctly today because
+//! tier_proximity (Hot=1.0) carries the load — the working-set
+//! members all score the same on non-tier factors so the relative
+//! ordering reflects what matters in PR-3d's scope: how hot.
+//!
+//! The semantic / outcome / trust integrations are independent
+//! lane work; each can land separately + recall scoring improves
+//! without re-touching this source.

+//! `demand-aligned-recall` PR-2: the `DemandAlignedRecall` trait +
+//! the composite types its methods reference. Per GENOME-FOUNDRY-
+//! SENTINEL Part 7.
+//!
+//! PR-1 (#1366) shipped the typed primitives (ResidencyHint,
+//! RecallScore, RecallScope, FreshnessTarget, TaskKind, TrustClass,
+//! AcquireSource, PeerId, RecallError). This PR adds:
+//!
+//! - The trait itself — `recall` + `replay` method signatures
+//! - `CapabilityQuery` — the input to `recall`: what kind of task,
+//!   resource budget, scope, freshness target, hard pins
+//! - `RecallContext` — who's asking and what they already have hot
+//! - `RankedPool` — the output: ranked layers + experts + engrams
+//!   with per-artifact `ResidencyHint` (from PR-1)
+//! - `RecallScoreWeights` — governor-tunable weights with a sum-to-1
+//!   invariant + a constructor that enforces it
+//! - `ArtifactRef` + `LoRALayerRef` / `MoEExpertRef` / `EngramRef`
+//!   typed wrappers around `ArtifactId`
+//! - `RecallBudget` — the memory + time budget the persona allocates
+//! - Stub placeholders for `OutcomeWindow` / `TrajectoryHint` /
+//!   `CompositionRef` / `CompositionHint` / `RecallTrace` —
+//!   GENOME-FOUNDRY-SENTINEL names these but their full shapes
+//!   depend on sentinel + composer modules that aren't built yet.
+//!   PR-2 ships opaque newtypes so the trait compiles; the shapes
+//!   grow in dedicated PRs.
+//!
+//! ## What PR-2 does NOT ship (PR-3)
+//!
+//! - The scoring function (semantic / outcome_history / recency /
+//!   tier_proximity / provenance_trust) — PR-3's `scoring.rs`
+//! - `grid_penalty(latency_ms)` cost curve — PR-3
+//! - `recency_decay(last_used, now, half_life)` — PR-3
+//! - `LocalDemandAlignedRecall` impl with the actual cache walks —
+//!   PR-3
+//! - Working-set-manager integration (via #1362's bus hook) — PR-3

+//!
+//! Each role has different eviction policy (LRU-within-turn,

+//! that the working-set-manager (PR-3) calls without caring which
+//! role it's talking to. The IMPLEMENTATIONS specialize.
+//!
+//! This is the OpenCV-style polymorphism pattern from CLAUDE.md: one
+//! interface, many implementations, AIs (or sentinel) can swap them
+//! at runtime via the governor's `Vec<TierConfig>`.

+//! explicitly, and because typed wrappers make `audit_access(persona,
+//! page)` impossible to call with the arguments swapped. When a

+//! Substrate governor cascade evaluator — Lane H PR-3c1 per
+//! GENOME-FOUNDRY-SENTINEL #1327 Part 11 §"Adjustment Cascade".
+//!
+//! PR-3b (#1354) shipped `LocalSubstrateGovernor` that RECORDS
+//! pressure signals. This PR-3c1 ships the pure-function CASCADE
+//! EVALUATOR — given (current cascade step, incoming signal, time-in-
+//! step), decide whether to advance, hold, or retreat.
+//!
+//! PR-3c2 wires this evaluator into `on_pressure_signal` to actually
+//! transition the governor's cascade_step + rewrite policy fields per
+//! the action.
+//!
+//! ## Cascade semantics (from spec)
+//!
+//! 6 steps, 0 = normal, 5 = max throttle. Each step has:
+//! - An **enter** condition (any signal can trigger advance)
+//! - An **exit** condition (ALL clear required to retreat — the
+//!   hysteresis that prevents oscillation)
+//! - A **time-in-step** requirement before further advance (slows
+//!   the cascade so brief spikes don't immediately escalate)
+//!
+//! ## Anti-oscillation: restore-speculation-one-step-later
+//!
+//! Spec rule: when retreating from step N → step N-1, the
+//! speculation level is restored ONE STEP LATER than the rest of the
+//! policy. Concretely: drop speculation on advance (step 1), restore
+//! on retreat (step 0 → step -1, which is a no-op). The "one step
+//! later" semantics: if pressure cleared at step 1, retreat to step 0
+//! but keep speculation throttled until the NEXT retreat opportunity.
+//! Since step 0 IS the lowest, the restoration happens "naturally" on
+//! the next pressure-clear evaluation that confirms sustained calm.
+//!
+//! This file ships the pure-function evaluator. PR-3c2 wires the
+//! `apply_action_to_policy` side-effect.
+//!
+//! ## Failure-mode discipline
+//!
+//! - All thresholds are typed + named (no magic floats / ints scattered
+//!   through call sites)
+//! - `evaluate_next_step` is pure — same inputs → same output. PR-3c2
+//!   tests the integration; PR-3c1 tests the rule.
+//! - No silent skip on unknown signal kinds — every variant of
+//!   `PressureSignal` participates in evaluation, even if some are
+//!   no-ops for the current step (`UserActive` doesn't trigger
+//!   advance, but the evaluator returns Hold rather than panic).

+//! `LocalSubstrateGovernor` — reference impl of the `SubstrateGovernor`
+//! trait. Lane H PR-3b per GENOME-FOUNDRY-SENTINEL #1327 Part 11.
+//!
+//! PR-3a (#1352) shipped policy SELECTION (`HardwareClass + Vec<PolicyFile>
+//! → PolicyFile`). This PR-3b ships the implementation that PUBLISHES
+//! the selected policy + holds the cascade-snapshot state. Other
+//! modules (tier stores, recall, composer, speculator) read via
+//! `current_policy()` — wait-free `Arc<GovernorPolicy>` clone.
+//!
+//! ## Scope of PR-3b
+//!
+//! - `LocalSubstrateGovernor` struct holding `Arc<ArcSwap<GovernorPolicy>>`
+//!   plus `Mutex<GovernorSnapshot>` (snapshot history is mutex-protected;
+//!   policy reads are arc_swap'd lock-free)
+//! - Impl `SubstrateGovernor` trait: `current_policy + on_hardware_detected
+//!   + on_pressure_signal + snapshot`
+//! - `new(initial_policy)` constructor
+//! - `on_hardware_detected(hw)` selects + publishes a new policy by
+//!   re-running the policy_selector logic over the cached candidate
+//!   list (caller supplies the candidates via `set_candidates`). If
+//!   selection fails, the typed error returns to the caller and the
+//!   current policy remains intact.
+//! - `on_pressure_signal(signal)` for PR-3b: RECORDS the signal in
+//!   recent_signals (bounded ring) + increments cascade_transition_count
+//!   when a signal-bearing state change occurs. The full threshold +
+//!   hysteresis cascade lands in PR-3c.
+//! - `snapshot()` returns a `GovernorSnapshot` clone with current
+//!   policy + transition count + recent signals
+//!
+//! ## Concurrency model
+//!
+//! Reads (`current_policy`) are wait-free `arc_swap` loads + `Arc`
+//! clones. A composer reading the policy 1000× per turn pays no
+//! contention cost.
+//!
+//! Writes (`on_hardware_detected`, `on_pressure_signal`) hold a small
+//! mutex on the snapshot history + atomically publish via `arc_swap`.
+//! Mutex hold time should be under a microsecond.
+//!
+//! ## What this PR DOES NOT do
+//!
+//! - Cascade state machine + thresholds (PR-3c)
+//! - File watcher / hot reload (PR-3d)
+//! - PressureBroker subscription wiring (PR-4)
+//! - Policy directory discovery (PR-3d); callers must provide explicit
+//!   candidates via `set_candidates`

+//! TOML policy file loader (Lane H PR-2, substrate-governor: policy_file).

+//! ## What this PR DOES NOT do
+//!
+//! - File system watch / hot reload (PR-3 wires `notify` crate).
+//! - Directory scanning / filesystem policy discovery.
+//! - Cascade state machine + threshold logic (PR-3).
+//! - Merging `local.toml` overlay (PR-3 — overlay format spec'd
+//!   inline below for forward-compat).
+//! - PressureBroker subscription (PR-4).
+//!
+//! ## Failure-mode discipline
+//!
+//! Same posture as `inference_capability::gguf_loader` (PR-2 of
+//! PIECE-5): every required field returns typed Err on missing/
+//! malformed; no silent defaults. The recall_weights validation
+//! enforces sum-to-near-1.0 (within 1% tolerance) — silently
+//! accepting wildly unbalanced weights would produce garbage
+//! ranked-pool scoring.

+//! Policy directory discovery and hot reload for `LocalSubstrateGovernor`.
+//!
+//! This module is deliberately small: it loads TOML policy files through
+//! `policy_file`, swaps the fully parsed candidate set into the governor,
+//! and keeps a `notify` watcher alive so operator edits can trigger the
+//! same reload path. Broken directories or malformed files return typed
+//! errors. The watcher callback records and logs failures instead of
+//! replacing a good candidate set with junk.

+//! Lane H PR-4 of the substrate governor stack. The broker (CBAR-SUBSTRATE
+//! Lane E) emits `PressureAlert` events whenever a registered pool crosses
+//! the broker's threshold OR relief eviction fires. The governor's cascade
+//! consumes typed `PressureSignal` enums. This module is the pure-function
+//! bridge between the two surfaces.
+//!
+//! Per GENOME-FOUNDRY-SENTINEL.md Part 11 line 1121: "PressureBroker
+//! informs the SubstrateGovernor. Pressure signals from the broker drive
+//! the governor's adjustment cascade. The broker keeps owning admission;
+//! the governor owns sizing."
+//!
+//! ## Scope of this PR
+//!
+//! - `alert_to_signal` — pure function: PressureAlert → Option<PressureSignal>
+//! - `governor_alert_sink` — factory: wraps a governor as an `AlertSink`
+//!   the broker can register via `PressureBroker::add_alert_sink`
+//!
+//! ## NOT in this PR
+//!
+//! - Wiring the sink into `PressureBrokerModule`'s boot path. That lives
+//!   in a follow-up; the bridge is the data-side primitive, the wiring is
+//!   a separate concern (lets reviewers reason about each independently).
+//! - Pool-name-aware mapping (e.g. `vram` pool → `VRAMHigh`, `docker`
+//!   pool → `DiskHigh` if/when that variant lands). Today's broker
+//!   pools are memory-adjacent (DockerTierPool disk usage,
+//!   HFCacheTierPool disk usage, GPU pool VRAM via GpuMemoryManager);
+//!   `SystemMemHigh` is the conservative single-mapping that the
+//!   cascade reacts to identically. Refinement is a follow-up once
+//!   pool tier_name conventions stabilize.
+//!
+//! ## Failure-mode discipline
+//!
+//! Same posture as the rest of Lane H: no silent default-on-error. The
+//! mapping is total (every alert produces either Some signal or None
+//! explicitly), and the sink forwards only when Some. Normal / Warning
+//! tier alerts produce None — the cascade explicitly only reacts to
+//! High+ per the spec's threshold table (Part 11 §"Adjustment Cascade").

+//! Substrate Governor typed surface — Lane H PR-1 (substrate-governor:
+//! governor-types) per GENOME-FOUNDRY-SENTINEL #1327 Part 11.
+//!
+//! The governor is the DVFS layer for the AI substrate. The ONE Rust
+//! subsystem that makes "same code on MacBook Air and RTX 5090" real:
+//! detect hardware at boot, write the policy file, expose a read-only
+//! `current_policy()` to every other subsystem, adjust at runtime under
+//! pressure, and reverse cleanly when pressure releases. Every other
+//! subsystem in this design — tier stores, recall, composer, speculator,
+//! foundry, sentinel, sharing protocol — reads the governor and never
+//! writes back. The governor IS the single source of truth for sizing.
+//!
+//! ## PR-1 scope (this file)
+//!
+//! Pure typed surface. No impl, no TOML loader, no cascade state
+//! machine, no probe wiring. Later slices ship policy parsing,
+//! selection, cascade, and pressure-signal subscriber wiring.
+//!
+//! This matches the rate_proposals / generate_recipe / PIECE-5 PR-1
+//! cadence — typed surface first, impl second, integration third.
+//!
+//! ## Hardware bridge
+//!
+//! `classify_hardware(profile: HardwareProfile) -> HardwareClass` is
+//! the pure function that maps my just-shipped `hw_probe` (PIECE-5
+//! PR-3 #1335) output to the typed governor input. It's the seam
+//! between the probe layer (boolean flags + numeric VRAM/RAM) and the
+//! governor layer (typed enum classification). PR-2 of substrate-
+//! governor wires the actual TOML policy file selection off the
+//! resulting `HardwareClass`.

+//! `MetalMonitor` — `GpuMonitor` impl for macOS.
+//!
+//! Per §12 of `docs/architecture/PERSONA-CONTEXT-PAGING.md`: the prior
+//! `GpuMemoryManager`'s Metal path treated `recommendedMaxWorkingSetSize`
+//! as live free memory. It isn't — it's a STATIC lifetime hint from the
+//! driver about the total budget the GPU can address. Process pressure
+//! and system pressure both went unreported. A video game grabbing VRAM
+//! never registered.
+//!
+//! This monitor distinguishes the four signals the policy actually needs:
+//!
+//! - `total_bytes` → Metal `MTLDevice.recommendedMaxWorkingSetSize` (still
+//!   the right source for TOTAL — only wrong as a "free" proxy).
+//! - `free_bytes` → Mach `host_statistics64(HOST_VM_INFO64)` summing
+//!   free + speculative + inactive page counts × page size. System-wide
+//!   free; the signal that catches "another app grabbed our headroom."
+//! - `process_bytes` → Mach `task_info(mach_task_self(), TASK_VM_INFO)`
+//!   → `phys_footprint`. This process's authoritative footprint, including
+//!   unified-memory GPU buffers mapped into our address space.
+//! - `utilization` / `temperature_c` / `power_watts` → IOReport.framework.
+//!   No maintained Rust crate; requires our own Objective-C runtime shim.
+//!   Phase 2.0a-IOReport ships separately. For now these return defaults
+//!   (0.0 / None) so the policy can still rely on memory-pressure signals
+//!   — the load-bearing signal — without blocking on the IOReport work.
+//!
+//! ## Unified vs discrete memory (task #163 fix)
+//!
+//! Apple Silicon (M1/M2/M3/...) uses **unified memory**: CPU and GPU
+//! share one address space, so system VM stats ARE the right "GPU
+//! free" signal. Intel Macs with a discrete GPU (AMD Radeon Pro Vega,
+//! NVIDIA, etc.) use **discrete memory**: the GPU has its own VRAM
+//! pool separate from system DRAM. Conflating the two pools causes
+//! the `free <= total + 10%` invariant to fail catastrophically —
+//! e.g., on a MacBookPro15,1 with a 4 GB Vega, system free pages
+//! report 20 GB while VRAM total reports 4 GB.
+//!
+//! The fix: detect `MTLDevice.hasUnifiedMemory` at construction time
+//! and branch the sampler. On unified, the existing Mach VM path is
+//! correct. On discrete, use `MTLDevice.currentAllocatedSize` for
+//! this-process GPU usage and derive `free = total - allocated`. The
+//! discrete approximation OVER-reports free (it ignores other
+//! processes' GPU use) but always satisfies `free <= total`, which is
+//! the invariant the pressure-broker relies on. IOReport.framework
+//! (Phase 2.0a) gives system-wide GPU usage and tightens this later.
+//!
+//! Module layout (Joel's modularize-to-simplify principle):
+//!
+//!   - `mod.rs` (this file) — `MetalMonitor` struct + `GpuMonitor` impl +
+//!     tick spawn. The policy-facing surface.
+//!   - `mach_ffi` — Mach VM FFI (structs, type aliases, raw read fns).
+//!     Independently testable; separation caught the clashing-extern bug
+//!     from the original mono-file version by making the FFI layer its
+//!     own visible surface.

+//! the substrate carries — personas, Claude Code sessions, Codex
+//! sessions, Joel-at-a-terminal, jtag CLI invocations, future web
+//! users. Same shape, same table, foreign-keyable from every other
+//! entity (engrams, work cards, captures, the lot).
+//!
+//! Per the Android-Context analogue: Identity is what makes
+//! `&ctx` mean "this specific actor instance" rather than "the
+//! process's global airc handle." There is no global. Code that
+//! acts on the substrate either takes a `&Context` (which carries
+//! an `Identity`) or it's a pure function.
+//!
+//! ## Why this is an Entity (not a struct + JSON file)
+//!
+//! Per [[no-sql-everything-through-orm-entities]] EVERY storable
+//! datum goes through the ORM + entity registration. The prior
+//! shape — `PersonaInstanceInfo` struct persisted as
+//! `~/.continuum/personas/<name>/seed.json` — predates the
+//! `#[derive(Entity)]` macro that #1519 / task #166 landed. With
+//! the derive macro available, hand-rolled JSON-on-disk is
+//! technical debt: untyped, non-queryable, no FK, no schema
+//! migration.
+//!
+//! Identity uses Pattern A of the derive macro (canonical) —
+//! `#[entity(primary_key)] id: Uuid` pulls in BaseEntity columns
+//! (`id`, `createdAt`, `updatedAt`, `version`) automatically.
+//!
+//! ## Why `id == airc peer_id`
+//!
+//! Per [[persona-identity-derives-from-source-id]]: a persona's
+//! peer_id IS its substrate identity. Same applies to every actor
+//! kind — the airc Ed25519 keypair is what makes you YOU on the
+//! substrate. So Identity's `id` is the peer_id directly, not a
+//! separate continuum-side surrogate. Other entities that need to
+//! reference an actor FK on `Identity.id` and route via airc
+//! automatically.
+//!
+//! ## Out of scope for this slice
+//!
+//! - `Context` struct wrapping Identity + services + captures
+//!   (Slice 2 of task #142)
+//! - Bootstrap paths per IdentityKind (fresh Claude Code session
+//!   minting its own Identity row + airc home; jtag CLI invocation
+//!   minting ephemeral; etc. — Slice 3)
+//! - `&ctx` ubiquitous refactor across substrate APIs (Slice 4)
+//! - Migration of `PersonaInstanceInfo` callers to read from
+//!   Identity table (Slice 1B, follow-up PR)

+//! AircRemoteInferenceAdapter — "the same command across the wire."
+//!
+//! Joel (2026-05-31): "grid inference and they're just the same
+//! command just executed across the wire and airc substrate
+//! delivered payloads."
+//!
+//! ### Architectural contract
+//!
+//! Implements `AIProviderAdapter` whose transport is airc instead
+//! of llama.cpp. Callers see no difference between:
+//!
+//! ```ignore
+//! // LOCAL — LlamaCppAdapter on Apple Silicon via Metal
+//! let response = adapter.generate_text(request).await?;
+//!
+//! // REMOTE — AircRemoteInferenceAdapter routing over airc to a peer
+//! let response = remote_adapter.generate_text(request).await?;
+//! ```
+//!
+//! Both impls return `TextGenerationResponse`. Everything above the
+//! adapter trait (handle store, lane coordinator, RAG inspection,
+//! persona response, chat module, sentinel review) treats remote
+//! and local identically.
+//!
+//! ### Module layout
+//!
+//! - [`protocol`] — wire types (`RemoteInferenceRequest`,
+//!   `RemoteInferenceResponse`, `RemoteInferenceError`). Pure data
+//!   + serde + ts-rs.
+//! - [`transport`] — `AircInferenceTransport` trait (one method:
+//!   `send_request`) + a stub for tests. Production impl that
+//!   speaks to a live airc daemon is its own slice (task #108
+//!   follow-up); the trait shape is stable.
+//! - [`adapter`] — `AircRemoteInferenceAdapter` implementing
+//!   `AIProviderAdapter`. Wraps any `AircInferenceTransport` Arc.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-is-an-adapter-always-in-the-loop]] — the remote
+//!   adapter is a peer impl of the same trait; cloud / local /
+//!   heuristic / remote-grid all expose the same surface.
+//! - [[airc-headers-are-the-routing-layer]] — the wire envelope
+//!   includes typed metadata (correlation_id, persona_id, peer
+//!   target hint) so routing decisions happen on headers, not on
+//!   payload inspection.
+//! - [[host-the-seemingly-impossible]] — this is the substrate's
+//!   structural answer for the Intel Mac and any
+//!   constrained-locally host. Reflective work runs locally on
+//!   the heuristic; real-model work routes over airc to whichever
+//!   peer has capacity.

+//! request envelope to a remote peer and await the response.
+//!
+//! Production impl (TBD, task #108 follow-up) speaks to the live
+//! airc daemon. This module ships:
+//! - The trait shape (stable; production impl plugs in without
+//!   touching adapter or wire types).
+//! - `StubInferenceTransport` — closure-driven stub for unit tests.
+//! - `LocalAdapterTransport` — a "round-trip via local adapter"
+//!   variant that lets a single-process test prove the
+//!   AircRemoteInferenceAdapter is functionally identical to a
+//!   local adapter when the transport happens to call back to a
+//!   local one. This IS the "same command across the wire" proof.

+//! Model-architecture probe for safe `n_seq_max > 1` (multi-seq
+//! continuous batching) in `LlamaCppAdapter`.
+//!
+//! Joel (2026-05-31): "Key is low latency. It's everything especially
+//! in video chat. And not stupid models." The prior-attempt failure
+//! mode that this probe defends against is enabling multi-seq
+//! continuous batching on an architecture that llama.cpp's Metal
+//! graph aborts on — exactly the qwen3.5 / Gated-Delta-Net abort that
+//! historically forced `n_seq_max = 1` everywhere.
+//!
+//! ### What the probe answers
+//!
+//! Given a GGUF's `general.architecture` string, return a typed
+//! verdict:
+//!
+//! - `SafeForMultiSeq` — standard transformer (Llama, Qwen-2.5,
+//!   Gemma-2, Mistral, …) — caller may set `n_seq_max > 1`.
+//! - `SingleSeqOnly` — recurrent / state-space / hybrid
+//!   architecture that llama.cpp's batched decode aborts on
+//!   (qwen3, mamba, rwkv, jamba, …). Caller MUST stay at
+//!   `n_seq_max = 1`; the adapter's load path enforces this as
+//!   defense in depth.
+//! - `Unknown` — architecture not in the curated list. Default to
+//!   single-seq (the safe choice). When new architectures land,
+//!   add them to the SAFE or UNSAFE list.
+//!
+//! ### Defense in depth
+//!
+//! Per the realistic-lane build plan, the adapter's `load()` calls
+//! `probe_gguf_batching_safety()` and clamps `n_seq_max` to 1 if
+//! the verdict is `SingleSeqOnly` (regardless of what the caller
+//! configured). This is the substrate's safety net — coordinator
+//! wiring can blindly pass `lane_budgets.max_concurrency` through
+//! and the probe handles model-family safety.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-scarcity-economics]] §"prior attempt was rather
+//!   shitty" — repeating the qwen3.5 abort is the exact failure
+//!   mode this probe rules out by construction.
+//! - [[observability-is-half-the-architecture]] — when the probe
+//!   clamps, it emits a `tracing::warn` line so the operator sees
+//!   the safety net firing, not silent quality loss.
+//! - [[commands-are-kernel-level-and-compose]] — the probe is a
+//!   pure classification function; the adapter is the only
+//!   consumer. No command-level visibility (callers ask for N;
+//!   the substrate decides).

+//! InferenceCoordinator — composes existing substrate primitives
+//! into multi-persona-one-model serving per
+//! [[INFERENCE-LANES-REALISTIC.md]].
+//!
+//! Joel (2026-05-31): "Yeah the inference command doesn't do this.
+//! It's smart subsystems and daemons. Commands are dumb and short."
+//! "We weren't clever enough with our lanes."
+//!
+//! ### What this layer does
+//!
+//! The coordinator owns the LANE LIFECYCLE — admission, lease + memory
+//! accounting, handle binding, eviction. The
+//! `ai/inference/{open,generate,close}` command surface (handle module)
+//! routes through here. The adapter trait + handle store stay
+//! unaware; the coordinator wraps both.
+//!
+//! ### Composition (no reinvention)
+//!
+//! - `plan_adaptive_throughput` from `cognition::adaptive_throughput`
+//!   makes admission decisions keyed by `target_silicon`.
+//! - `FootprintRegistry::acquire_lease` / `release_lease` from
+//!   `inference::footprint_registry` mirrors the lease into byte
+//!   accounting in one call.
+//! - `InferenceHandleStore` from `inference::handle_store` owns the
+//!   actual adapter session.
+//! - `Lane` from `inference::lane` binds (persona, task, lease,
+//!   handle).
+//!
+//! ### Doctrine alignment
+//!
+//! - [[commands-are-kernel-level-and-compose]] — coordinator is a
+//!   plain Rust component (not a ServiceModule). The handle module
+//!   delegates to it; callers never reach it directly.
+//! - [[observability-is-half-the-architecture]] — Step 2 ships
+//!   capture-event SHAPES (LaneCaptureEvent enum, sink trait, Noop
+//!   default). The wiring through `InferenceHandleModule` in Step 3
+//!   adds capture-aware delivery.
+//! - [[host-the-seemingly-impossible]] — the coordinator is what
+//!   makes "16 personas on commodity hardware" real. Lane
+//!   accounting + admission + eviction compose into the substrate's
+//!   defining boast.

+//! `CoordinatorResourcePool` — adapts `InferenceCoordinator` to the
+//! `paging::pool::ResourcePool` trait so `PressureBroker` can drive
+//! lane eviction automatically when host memory tightens.
+//!
+//! Joel (2026-05-31): "Yeah keep going and keep merging." This is
+//! the substrate-side glue that closes the realistic-lane build
+//! plan's pressure response — without it, the coordinator has the
+//! `evict_under_pressure` method but no one calls it. With it, the
+//! PressureBroker's tier-monitoring loop fires the substrate's
+//! pressure-driven eviction the same way it fires VRAM eviction on
+//! the Docker tier.
+//!
+//! ### Why a wrapper instead of impl-on-coordinator
+//!
+//! The coordinator doesn't depend on `paging` (the doctrine layering
+//! goes inference → paging, not the other way). Implementing
+//! `ResourcePool` directly on `InferenceCoordinator` would push that
+//! dependency upstream. The wrapper sits in the inference module,
+//! depends on both, and stays small + auditable.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-scarcity-economics]] §"commands cannot negotiate
+//!   this" — the wrapper is internal substrate plumbing. Callers
+//!   never see it; pressure response is automatic when the wrapper
+//!   is registered with the broker.
+//! - [[observability-is-half-the-architecture]] — every
+//!   `evict_at_least` call surfaces through the coordinator's
+//!   existing `LaneCaptureSink` (LaneEvicted events fire per
+//!   evicted lane). The wrapper itself stays thin.

+//! Per-component memory footprint registry — "what are we made of?"
+//!
+//! Per §13 of `docs/architecture/PERSONA-CONTEXT-PAGING.md`: GpuMonitor
+//! (§12) tells the policy WHAT pressure looks like; the registry tells
+//! it WHAT to do about it. Without per-component attribution the policy
+//! knows "we're at 90% of process limit" but has no idea WHICH of N
+//! things in our process is biggest, cheapest to spill, or worth
+//! keeping hot.
+//!
+//! Every allocation site (KV slots, LoRA adapters, model weights,
+//! render buffers, tokenizer caches, audio/video pipelines) reports
+//! bytes via a single DashMap keyed on (persona, recipe, backend,
+//! resource type, residency). Reporting is unconditional and cheap;
+//! no `#[cfg]`, no platform branches.
+//!
+//! The registry's `cheapest_eviction_for` is what makes paging real:
+//! given "free X bytes," it returns a plan picking the lowest-cost
+//! combination of evictable entries. Cost-driven, not type-prioritized.
+//!
+//! Module layout:
+//!
+//! - `mod.rs` (this file) — `FootprintRegistry` impl, global singleton,
+//!   integration tests across the registry's behavior.
+//! - `types.rs` — pure data shapes (ResourceType, FootprintKey,
+//!   FootprintEntry, EvictionPlan, RegistryHealth, RegistrySnapshot)
+//!   + key constructors. Independently testable for layout/equality.
+//! - `costs.rs` — spill/reload heuristics per ResourceType + tests for
+//!   policy invariants (KV cheaper than ModelWeights to spill, etc.).
+//!   The file Phase 4.0 telemetry will replace as measurements mature.

+//! InferenceHandleModule — ServiceModule wrapper exposing the
+//! handle store as `ai/inference/open` / `ai/inference/generate` /
+//! `ai/inference/close` / `ai/inference/inspect` commands.
+//!
+//! Joel (2026-05-31): "Yeah the inference command doesn't do this.
+//! It's smart subsystems and daemons. Commands are dumb and short."
+//!
+//! ### What this module is
+//!
+//! The dumb-command layer. Routes open/generate/close to
+//! `InferenceHandleStore` with minimal logic — parse envelope,
+//! validate, call store, materialize response. NO scheduling, NO
+//! batching, NO LoRA paging policy, NO base-model-sharing decisions.
+//! Those live in the smart subsystems + daemons that sit BEHIND
+//! this command surface ([[inference-scarcity-economics]] task #109).
+//!
+//! ### Adapter resolution
+//!
+//! The `open` handler resolves the requested provider via the
+//! shared `AdapterRegistry` (the same registry that `inference/llm/
+//! request` uses). The handle store doesn't touch the registry —
+//! the module is the bridge between "I want provider X" (the
+//! caller's view) and "I have an Arc<dyn AIProviderAdapter>" (the
+//! store's contract).
+//!
+//! ### Doctrine alignment
+//!
+//! - [[commands-are-kernel-level-and-compose]] — this module ONLY
+//!   handles command envelopes + routing; never reaches into
+//!   adapter or store internals
+//! - [[inference-is-an-adapter-always-in-the-loop]] — these are the
+//!   canonical handle-shape commands callers + tests will route
+//!   through; one-shot `inference/llm/request` remains the legacy
+//!   path for migration
+//! - [[inference-scarcity-economics]] §"commands are dumb, daemons
+//!   are smart" — this module is the dumb interface; smart bits
+//!   land later as separate components without changing this
+//!   command surface
+//! - [[rust-is-the-core-node-is-the-shell]] — pure Rust ServiceModule

+//! Inference handle store — establish-once / reuse-many sessions.

+//! Joel (2026-05-31): "Maybe you get a handle first then inference?
+//! Establish once? Keep loaded or it pages itself intelligently but
+//! still a handle. That way you've got a remote handle or a cloud
+//! handle. Etc. typically you call these things repeatedly in."

+//! Real inference is rarely one-shot. A persona service cycle, a
+//! RAG inspection turn, a sentinel review may issue dozens or
+//! hundreds of inference calls in close succession. Every one
+//! reloading the model, reopening the cloud connection, or
+//! re-routing through airc is wasteful. The session pattern: open
+//! once, reuse for many calls. Eventually the substrate's pressure
+//! policy evicts cold sessions LRU-style (same shape as
+//! [[LORA-GENOME-PAGING]] adapter eviction).
+//!
+//! ### Library layer
+//!
+//! This module ships the library piece — `InferenceSession`,
+//! `InferenceHandleStore`, and the open/generate/close lifecycle.
+//! The ServiceModule wrapper that exposes `ai/inference/open`,
+//! `ai/inference/generate`, `ai/inference/close` as commands lives
+//! in a follow-up slice. Same staging approach as `rag_inspect`:
+//! pure-Rust library first, command surface on top.
+//!
+//! ### Adapter-agnostic
+//!
+//! Works uniformly for every AIProviderAdapter — Heuristic,
+//! Anthropic, OpenAI-compatible, LlamaCpp, future AircRemote. The
+//! session holds whatever per-adapter state matters (system prompt,
+//! sampling defaults, LoRA layer config, persona scope); the
+//! adapter trait stays unchanged.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-is-an-adapter-always-in-the-loop]] — handle pattern
+//!   is THE canonical inference shape; one-shot generate is a
+//!   convenience that wraps open+generate+close internally
+//! - [[cell-processor-command-runtime]] — HandleRef is the substrate's
+//!   universal session primitive; reusing it keeps the inference
+//!   surface compositional with data cursors, generator handles,
+//!   chat sessions
+//! - [[observability-is-half-the-architecture]] — every open/generate
+//!   /close records timing, generation_count, last_used_ms so
+//!   mechanic-shop introspection can answer "is this session warm?
+//!   how often is it generating? when was the last call?"
+//! - [[rust-is-the-core-node-is-the-shell]] — handle store lives in
+//!   Rust; TS commands route through the eventual ServiceModule

+//! Lane — the unit of inference budget per
+//! [[INFERENCE-LANES-REALISTIC.md]].
+//!
+//! Joel (2026-05-31): "I think we weren't clever enough with our
+//! lanes. The goal should be to ideally cover the needs of the
+//! persona, while being realistic."
+//!
+//! A lane is `(persona, TaskKind, ThroughputLease)` over the shared
+//! base model. Multiple lanes share the loaded model bytes; only KV
+//! cache + persona-scoped state differs per lane. Continuous
+//! batching multiplexes lanes through the same forward pass.
+//!
+//! This is the substrate's "ONE model, N lanes" cleverness — the
+//! prior-attempt failure mode was conceiving lanes as separate
+//! model loads. Lanes are recipe-budgeted KV slots, not weight
+//! copies.
+//!
+//! ### Composition (no reinvention)
+//!
+//! Lane sits at the intersection of pre-shipped primitives:
+//!
+//! - [`crate::cognition::throughput_lease::ThroughputLease`] — the
+//!   slot primitive, including the revocation policy (Pinned /
+//!   Graceful / Hard) that the pressure broker honors.
+//! - [`crate::inference::recipe_budget::TaskKind`] — the canonical
+//!   per-task seed budget table.
+//! - [`crate::genome::working_set::PersonaId`] — the substrate's
+//!   persona identity type.
+//! - [`HandleRef`] — the inference handle the caller threads
+//!   through `ai/inference/{open,generate,close}`.
+//!
+//! The Lane glues these together. The InferenceCoordinator
+//! (`coordinator.rs`, lands next) owns a `DashMap<handle_id, Lane>`
+//! and decides admission via the existing `AdaptiveThroughputPlanner`.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[inference-scarcity-economics]] §"commands are dumb" — Lane is
+//!   internal substrate state, never visible at the command surface.
+//!   `ai/inference/open` returns a HandleRef; the Lane is bookkeeping
+//!   behind it.
+//! - [[host-the-seemingly-impossible]] — Lane is the unit through
+//!   which one model serves 16 personas on commodity hardware. No
+//!   tier-down; clever lane multiplexing.
+//! - [[observability-is-half-the-architecture]] — Lane lifecycle
+//!   events (admitted, evicted, demoted to Bench) emit through the
+//!   coordinator's capture sink (lands with the coordinator).

+//! `LlamaCppAdapter` — implements `AIProviderAdapter` by wrapping our
+//! in-process `LlamaCppBackend` (the bundled `llama` crate, statically
+//! linked against the vendored llama.cpp Metal/CUDA build).
+//!
+//! Why this exists:
+//!
+//! Docker Model Runner (DMR) ships a containerized llama-server. On Mac
+//! the container's Metal toolchain has been failing to compile the
+//! tensor-API source on M5/Apple10 hardware (verified 2026-04-19, log:
+//! `ggml_metal_library_init_from_source: error compiling source` →
+//! `has tensor = false`). Result: M5 inference at 22 tok/s — slower
+//! than M1 at 27 tok/s on the same model. The cripple is in DMR's
+//! container build, not in llama.cpp itself.
+//!
+//! This adapter bypasses DMR entirely — loads the GGUF in-process via
+//! our newer vendored llama.cpp build, which compiles Metal correctly
+//! against the host toolchain. Empirical win: 33 tok/s vs DMR's 22 tok/s
+//! on the same hardware (50% improvement, smoke test in
+//! `tests/llamacpp_metal_throughput.rs`).
+//!
+//! Other wins from owning the inference call directly:
+//! - No HTTP hop (in-process call vs localhost roundtrip)
+//! - Full control of `n_gpu_layers`, batch sizes, sampling
+//! - Direct access to LoRA hot-swap via `LlamaCppBackend::ensure_adapter`
+//! - Metal command-buffer timing available for real GPU-utilization
+//!   metrics (planned follow-up — addresses "we can't even see what
+//!   percent GPU was used" observability gap)
+//!
+//! Coexistence with DMR adapter:
+//! - Both registered. This adapter gets HIGHER priority (lower number)
+//!   so local Mac inference flows here first.
+//! - DMR remains the fallback for: cases where in-process load fails,
+//!   non-Mac platforms, or operators who prefer the container path.

+//! `inference-llm` PR-1: typed wire shapes for the local-LLM
+//! generation module. Per MODULE-CATALOG §II `inference-llm`.
+//!
+//! The module itself (composition → tokenizer → llama.cpp invoke →
+//! token stream + reprojection metadata) lands in PR-2/PR-3. PR-1
+//! ships the typed event surface so:
+//!
+//! - Producers (persona-cognition) can emit `InferenceRequest` per
+//!   the canonical shape
+//! - Consumers (sentinel-observer, VDD harness, audit-recorder)
+//!   can subscribe to `InferenceComplete` / `FirstTokenEmitted` /
+//!   `ResidencyFault` and start building against the wire today
+//! - Downstream PRs land the inference engine itself against this
+//!   already-frozen contract
+//!
+//! Same slice shape as the genome (#1346) and recall (#1366) PR-1s:
+//! pure data + serde + ts-rs exports + tests pinning every wire
+//! invariant. No I/O, no async, no traits.
+//!
+//! ## What PR-1 ships
+//!
+//! - `InferenceRequest` — `[InferenceRequest]` subscription event;
+//!   carries persona + composition_plan + prompt + budget + sampling
+//! - `InferenceComplete` — emission; carries persona + request id +
+//!   completion tokens + finish reason + elapsed_ms + tokens
+//! - `FirstTokenEmitted` — emission for time-to-first-token
+//!   observability
+//! - `ResidencyFault` — emission when inference would need a
+//!   not-currently-resident page; sentinel learns from these
+//! - `FinishReason` enum (Stop / MaxTokens / StopSequence / Error)
+//! - `SamplingParams` struct (temperature, top_p, top_k,
+//!   repeat_penalty)
+//! - `GenerationBudget` struct (max_tokens, max_duration_ms)
+//! - `InferenceRequestId` newtype around Uuid for typed request
+//!   correlation across the four events
+//! - `CompositionPlan` opaque stub — the composer module owns the
+//!   full shape; PR-1 ships a typed reference so InferenceRequest
+//!   compiles
+//!
+//! ## What PR-1 does NOT ship (PR-2 / PR-3)
+//!
+//! - `InferenceLlmModule` ServiceModule impl — PR-2
+//! - Tokenizer + composition-plan-to-tokens translation — PR-3
+//! - llama.cpp invocation + token streaming — PR-3
+//! - Reprojection metadata emission — PR-3 or separate
+//! - Bus wiring + Runtime registration — PR-2/PR-3
+//! - InferenceLlmCandidateSource (consumes DAR recall to build
+//!   composition plans) — that's a recall-side PR for later

+//! `inference-llm` PR-3a: canonical ArtifactKey constants +
+//! publishing helpers for the four inference events.
+//!
+//! Background: PR-1 (#1387) shipped the typed events. PR-2 (#1391)
+//! shipped the ServiceModule that emits InferenceComplete +
+//! FirstTokenEmitted as command responses. What's been missing
+//! is the artifact-dispatch path — the canonical ArtifactKeys
+//! downstream subscribers (sentinel-observer, VDD harness,
+//! audit-recorder) bind to.
+//!
+//! This module fills that gap with three building blocks (same
+//! pattern as my genome::bus PR-4 / #1358):
+//!
+//! 1. **Canonical `ArtifactKey` constants** — every inference event
+//!    has one stable key. Subscribers refer to the constant, not a
+//!    string literal, so the wire stays consistent across renames.
+//!
+//! 2. **Publishing helpers** — `publish_inference_complete`,
+//!    `publish_first_token_emitted`, `publish_residency_fault` —
+//!    serialize the typed event + publish through the artifact
+//!    dispatch path (#1339 + #1343).
+//!
+//! 3. **Subscriber convenience** — `subscribe_to_inference_events`
+//!    wires a module to all three response keys at once. Producers
+//!    subscribe separately if they need to observe their own
+//!    requests; that's not the common case (most observers want
+//!    completes + first-tokens + faults, not requests).
+//!
+//! ## What PR-3a does NOT ship
+//!
+//! - Wiring the helpers INTO `InferenceLlmModule::handle_command`
+//!   so it auto-publishes after each call — that's PR-3b. PR-3a
+//!   ships the wire so downstream subscribers can bind first.
+//! - Real LLM engine — that's PR-4 (LlamaCppAdapter integration)
+//! - InferenceRequest artifact subscription (the module subscribes
+//!   to requests via this path instead of going through the command
+//!   bus) — separate PR; needs persona-cognition to publish via
+//!   bus first.

+//! `inference-llm` PR-2: `InferenceLlmModule` ServiceModule impl.
+//!
+//! PR-1 (#1387) shipped the typed event surface. PR-2 wires the
+//! ServiceModule that accepts InferenceRequest commands + emits
+//! the response events. The actual llama.cpp invoke lands in PR-3;
+//! PR-2 ships a STUB inference that returns canned tokens so the
+//! seam is testable end-to-end + downstream consumers
+//! (sentinel-observer, VDD harness) can wire to it today.
+//!
+//! ## What PR-2 ships
+//!
+//! - `InferenceLlmModule` struct implementing `ServiceModule`
+//! - `inference/llm/request` command — accepts InferenceRequest
+//!   JSON, runs the stub inference, returns InferenceComplete +
+//!   FirstTokenEmitted as JSON
+//! - Stub inference returns 3 canned tokens [1, 2, 3] with
+//!   `FinishReason::Stop`. Documented as PR-3 deferral.
+//! - Tests pin the wire contract: request → response correlation
+//!   via `requestId`, finish reason, token count, TTFT field
+//!
+//! ## What PR-2 does NOT ship (PR-3)
+//!
+//! - Real llama.cpp invocation (`LlamaCppAdapter` integration)
+//! - Tokenizer (composition_plan → prompt_tokens)
+//! - Token streaming via channels (PR-2 is request/response)
+//! - Bus-event subscription path (`artifact_subscriptions`)
+//! - ResidencyFault emission on missing-page (needs working-set
+//!   integration)
+//! - Runtime registration (separate wiring PR or registers when
+//!   PR-3 lands the real engine)

+//! ORT GPU Execution Provider configuration — single source of truth.
+//!
+//! ## Why this exists
+//!
+//! Per Joel's architectural rule (2026-05-01): "lack of GPU integration is
+//! forbidden, GPU acceleration in all cases." Continuum runs on GPU
+//! everywhere — Metal native, Metal via Docker (DMR), CUDA via Docker GPU
+//! runner, Vulkan. CPU-fallback paths are categorically excluded.
+//!
+//! ORT (the `ort` crate wrapping ONNX Runtime) ships an implicit CPU
+//! Execution Provider as the final fallback when none of the GPU EPs in
+//! the user-supplied list can handle a node. That implicit fallback is
+//! exactly what this rule forbids — it's the silent-degradation vector
+//! that produced #964 (800-900% MLAS CPU spike during chat-induced
+//! embedding calls on Mac M5 Pro).
+//!
+//! ## What this provides
+//!
+//! `build_ort_gpu_execution_providers()` — returns the GPU EP list that
+//! every ORT consumer in this crate should use. Hard-fails with an
+//! actionable error when no GPU EP is configured for the current
+//! platform / cargo feature combination, so callers cannot accidentally
+//! pass an empty list to ORT (which would let the implicit CPU EP take
+//! over silently).
+//!
+//! ## Pre-fix bugs this surface fixes (#964)
+//!
+//! Before this helper, three call sites ALL had the same broken cfg
+//! gate: `#[cfg(all(feature = "coreml", target_os = "macos"))]`. There
+//! is no `coreml` feature in continuum-core's Cargo.toml — the actual
+//! feature is `metal` which propagates to `ort/coreml`. So the cfg
+//! attribute was always false, the CoreML EP was never added, and ORT's
+//! implicit CPU EP took every op. Three production sites:
+//!
+//!   - memory/embedding.rs       (fastembed)
+//!   - live/audio/tts/piper.rs   (TTS)
+//!   - live/audio/stt/moonshine.rs (STT)
+//!
+//! All three: dead GPU branch → silent CPU usage → 800-900% CPU spike.
+//!
+//! Centralizing here means ANY future ORT consumer in continuum-core
+//! gets the right cfg gating + the hard-fail enforcement automatically,
+//! and there is ONE place to add ROCm / OpenVINO / DirectML / etc. when
+//! those EPs become viable.
+//!
+//! ## Cargo feature matrix
+//!
+//!   --features metal    → CoreML EP (Mac, Apple Silicon GPU)
+//!   --features cuda     → CUDA EP (Linux+Nvidia, WSL+Nvidia, Windows+Nvidia)
+//!
+//! Coverage gaps tracked separately:
+//!   - Linux+AMD (ROCm EP) — needs ort/rocm feature wiring
+//!   - Linux+Intel (Vulkan/OpenVINO EP) — needs ort/openvino feature
+//!   - Windows-native (DirectML EP) — needs ort/directml feature
+//!
+//! These gaps mean we still hard-fail on those platforms today rather
+//! than silently routing to CPU — which is correct per the rule. Builds
+//! that fail here are a signal to add the missing EP wiring, not to
+//! relax the no-CPU-fallback constraint.

+//! Residency-gate enforcement helper (CBAR-PIECE-5 PR-4).
+//!
+//! Composes the three pure layers shipped in PR-1/PR-2/PR-3 into ONE
+//! function callers can invoke before launching a local-generation
+//! turn:
+//!
+//!   `enforce_residency(model_path) -> Result<ResidencyEvidence, Box<ResidencyBlock>>`
+//!
+//! Pass → caller gets typed evidence to record + proceeds with the turn.
+//! Block → caller refuses the turn rather than silently letting llama.cpp
+//! split layers to CPU.
+//!
+//! Production wiring lives in `LlamaCppAdapter::ensure_loaded`: before
+//! llama.cpp loads the selected GGUF, the adapter reads model metadata,
+//! probes hardware, runs this gate, and refuses with typed reasons if
+//! full GPU residency cannot be proven.
+//!
+//! ## Why a helper, not wired directly
+//!
+//! - The adapter load path is the narrow enforcement point: one model
+//!   load proves residency once before any local generation uses it.
+//! - The helper stays callable for future scheduler-level rechecks when
+//!   hardware pressure changes between turns.

+//! `&Path` → `QwenModelMetadata`. PR-3 wires both probe + this loader
+//! into the actual turn dispatcher.
+//!
+//! ## What gets extracted
+//!
+//! From the GGUF file's metadata map:
+//!
+//! - `general.architecture` (required) → `architecture` field, used to
+//!   index `{architecture}.block_count`.
+//! - `general.name` (optional) → `model_name`, falls back to the file
+//!   stem if missing.
+//! - `{architecture}.block_count` (required) → `layer_count`.
+//! - `general.file_type` (required) → mapped via `file_type_to_bytes_per_param`
+//!   to `bytes_per_parameter_quantized`.
+//! - `general.parameter_count` (optional) OR derived if absent →
+//!   `parameter_count_billions`.
+//! - Architecture-keyed lookup → `layer_kinds_needing_check`.
+//!
+//! ## Failure-mode discipline
+//!
+//! - **No silent fallback for required fields**: missing `block_count`,
+//!   missing `general.architecture`, or unknown `general.file_type`
+//!   value all return `Err` — never a guessed default. Same posture as
+//!   `backends::read_gguf_metadata` (Joel's 2026-04-23 fix removed all
+//!   the silent-llama-fallback paths there).
+//! - **`general.parameter_count` is OPTIONAL** with a typed fallback
+//!   that LOGS the inference (file_size × bytes-per-param-inverse).
+//!   The fallback path is loud — every caller sees "parameter_count
+//!   estimated from file size, not GGUF metadata" so a future PR can
+//!   tighten when canon files start carrying the field reliably.
+//! - **Unknown architecture**: not blocked here — the residency gate's
+//!   `unsupported_layer_kinds_on_backend` already filters per backend.
+//!   PR-2's job is to extract data, not gate. Returns `Ok` with an
+//!   empty `layer_kinds_needing_check`.
+//!
+//! ## What this DOES NOT do
+//!
+//! - Open the model for inference. That's `load_gguf_backend` in
+//!   `backends::mod`.
+//! - Probe hardware. That's `probe::probe_inference_capabilities`.
+//! - Decide whether the gate passes. That's `residency::check_residency_gate`.
+//! - Cache the metadata. Caller (PR-3) owns the cache decision.

+//! Hardware probe — populates `HardwareProfile` from runtime detection
+//! (CBAR-PIECE-5 PR-3).
+//!
+//! PR-1 (`residency.rs`) defined the gate types. PR-2 (`gguf_loader.rs`)
+//! reads model metadata from disk. This PR-3 populates the OTHER input
+//! to the gate — the live hardware profile — by probing Metal / CUDA /
+//! Vulkan independently and combining the result with CPU + RAM data
+//! from `sysinfo`.
+//!
+//! ## Why probe each backend independently
+//!
+//! `gpu::memory_manager::detect_gpu()` returns the FIRST backend that
+//! succeeds (Metal → CUDA → Vulkan → panic). That's correct for the
+//! production GpuMemoryManager — only one budget per node — but wrong
+//! for `HardwareProfile`, which has separate `has_metal`/`has_cuda`/
+//! `has_vulkan` flags. An NVIDIA-on-Linux host can have both CUDA AND
+//! Vulkan; the gate's `select_backend` uses the flags to pick CUDA over
+//! Vulkan (CUDA's llama.cpp kernels are more complete). If we only set
+//! whichever-detected-first, the flags lie.
+//!
+//! ## What this DOES NOT do
+//!
+//! - Allocate VRAM (free_vram is reported as total minus a reserve —
+//!   PR-4 wires `GpuMemoryManager::stats().total_used_mb` for the real
+//!   "what's free RIGHT NOW" number).
+//! - Trigger `GpuMemoryManager::detect()` (that's heavyweight + panics
+//!   on no-GPU; the probe must not).
+//! - Decide whether a model fits — that's `check_residency_gate`.
+//! - Choose a backend — that's `select_backend`.
+//!
+//! ## Failure-mode discipline
+//!
+//! - Probe NEVER panics. A CPU-only host returns a HardwareProfile with
+//!   `has_metal=false, has_cuda=false, has_vulkan=false, free_vram=0`.
+//!   The gate then surfaces `NoGpuBackendOnNode` — visible failure, not
+//!   silent CPU fallback.
+//! - Per-backend probes return `Option<(u64, String)>` — None means
+//!   "not available on this build/host." The orchestrator combines.
+//! - sysinfo failures fall back to conservative defaults (cpu_cores=1,
+//!   system_ram=0). Logged on the cognition channel so an observer
+//!   sees the fallback.

+//! Inference capability surface — local-side only (PR-1 of GRID-INFERENCE-ROUTING).
+//!
+//! This module ships the **data + pure derivation** layer the supervisor
+//! needs to describe what inference work this node can take. No grid
+//! wiring, no broadcast, no async — just:
+//!
+//! - [`types`] — wire-shape (ts-rs camelCase): `InferenceKind`,
+//!   `LatencyClass`, `HardwareProfile`, `InferenceCapability`,
+//!   `NodeCapability`. Carried by PR-2 (`GridCapabilityAnnouncer`)
+//!   across the mesh; consumed by PR-3 (`GridInferenceRouter`) when
+//!   scoring placement.
+//!
+//! - [`probe`] — pure function `probe_inference_capabilities(hw)` that
+//!   maps a hardware profile to its capability list. No IO, no globals
+//!   — synthetic profiles for the four hardware tiers vhsm-d1f4 named
+//!   (MacBook Air, M5 Pro, Blackwell, generic Dell) are testable
+//!   directly.
+//!
+//! - [`registry`] — `NodeCapabilityRegistry` in-memory map of
+//!   `node_id -> NodeCapability` with insert/remove/list/find_capable.
+//!   PR-2 owns the announcer + locking; this layer is sync, single-threaded.
+//!
+//! ## Why pure-functions slice first
+//!
+//! Per the rate_proposals / generate_recipe PR-1 cadence: data + pure
+//! derivation lands independently mergeable, with full test coverage,
+//! before any IPC / async wiring. PR-2 stacks the announcer on this
+//! surface; PR-3 stacks the router on PR-2.
+//!
+//! ## Failure-mode discipline (vhsm-d1f4 audit pass 1)
+//!
+//! - **No CPU fallback**: `probe_inference_capabilities` returns ZERO
+//!   capabilities for a CPU-only node. The grid router seeing "0
+//!   capabilities" + the supervisor admission gate failing > "GPU
+//!   advertised, then mid-inference CPU degrade".
+//! - **No hardcoded enums**: `InferenceKind(String)` newtype, not a
+//!   const enum. New backends plug in without a schema change.
+//! - **No `unwrap_or` / silent defaults**: every field carries explicit
+//!   data; no "default to zero VRAM and pretend it works."

+//! Qwen GPU residency gate (CBAR-SUBSTRATE missing piece #5, PR-1).
+//!
+//! `inference_capability::probe` (#1315) answers "does this node have an
+//! advertisable GPU at all?" The residency gate answers the next question
+//! one level deeper: "will the SELECTED MODEL actually fit with all
+//! layers on that GPU, evidenced not guessed?"
+//!
+//! The CBAR-SUBSTRATE spec (docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md
+//! §336 piece #5) requires that, before any local-generation turn runs:
+//!
+//! - The selected Qwen model is named explicitly,
+//! - The backend (Metal / CUDA / Vulkan) is named and matches platform,
+//! - GPU layer count is reported,
+//! - Unsupported layers are enumerated (Vulkan-llama.cpp gaps, etc.),
+//! - VRAM residency estimate covers all layers,
+//! - "CPU graph splits or unsupported Qwen layers are blockers unless the
+//!   turn is explicitly degraded with a visible reason."
+//!
+//! This module ships the **data + pure derivation layer**. No GGUF I/O,
+//! no runtime dispatch, no llama.cpp probe — those land in a future PR-2
+//! that wires the GGUF reader to populate `QwenModelMetadata` from
+//! `backends::read_gguf_metadata` + a small layer-count extractor, and
+//! wires the hardware probe to populate `HardwareProfile`. PR-3 wires
+//! the gate result into the actual turn dispatcher with a block-the-turn
+//! enforcement point.
+//!
+//! ## Failure-mode discipline
+//!
+//! Per vhsm-d1f4 audit pass 1 + the no_cpu_fallback contract:
+//!
+//! - **No partial GPU split**: if the model needs more layers than the
+//!   backend can hold on GPU, the gate **blocks** — it does not silently
+//!   split to CPU. The CBAR-SUBSTRATE spec says "CPU graph splits ... are
+//!   blockers unless explicitly degraded with a visible reason." This
+//!   module produces the visible reason (`BlockReason::PartialGpuSplit`);
+//!   the explicit-degrade path lives elsewhere.
+//! - **No silent unsupported-layer fallback**: Vulkan llama.cpp doesn't
+//!   support every Qwen op today; if the selected backend's compiled
+//!   kernel set is missing what the model needs, gate blocks with
+//!   `BlockReason::UnsupportedLayer`. The probe in #1315 already gates
+//!   Vulkan-only hosts away from native-GPU kinds; this gate is the
+//!   per-model second check.
+//! - **No assumed defaults**: every field comes from the inputs; no
+//!   `unwrap_or(4096)` / `unwrap_or("metal")` / etc.

+//! Continuum Core - Rust-first architecture for concurrent AI persona system
+//!
+//! Design principles:
+//! - Message passing via Tokio channels (no locks)
+//! - Trait-based abstractions (OOP interfaces)
+//! - Work-stealing concurrency (Tokio runtime)
+//! - Zero-copy where possible
+//! - Performance timing from the ground up
+//!
+//! Architecture: Rust is the brain, TypeScript is the face.
+//! Target: 60-70% Rust (cognition, compute, real-time), 30-40% TypeScript (UI only)
+
+// objc macros (sel!, msg_send!, class!) must be imported at crate root.
+// Used by live::video::metal_gpu_convert for Metal compute shader dispatch.

+//! Bevy Headless Avatar Renderer
+//!
+//! A single Bevy app instance renders all AI persona avatars simultaneously.
+//! Each avatar gets its own RenderLayer + Camera + render target texture.
+//! GPU readback delivers RGBA frames via crossbeam channels to LiveKit video loops.
+//!
+//! Architecture:
+//!   BevyAvatarSystem (singleton)
+//!     └── Bevy App (dedicated OS thread)
+//!           ├── Avatar slot 0: Camera → RenderTarget → Readback → channel

+//!           ├── ...
+//!           └── Avatar slot 15: Camera → RenderTarget → Readback → channel
+//!
+//! Performance: 16 avatars × 640×360 @ ~7fps effective readback (15fps Bevy tick).
+//! On Apple Silicon (shared memory + GPU bridge), readback is zero-copy IOSurface.
+//!
+//! ## Module Structure
+//!
+//! - `api` — BevyAvatarSystem singleton, public methods
+//! - `app` — Bevy App setup and system registration
+//! - `commands` — AvatarCommand processing
+//! - `readback` — GPU readback management
+//! - `setup` — Render slot allocation, readback entity spawning
+//! - `stats` — Memory stats, load monitoring, light visibility
+//! - `animation/` — Per-concern animation systems (blinking, breathing, etc.)
+//! - `types` — All components, resources, enums, structs
+//! - `scene/` — Scene graph, room, animation config
+//! - `skeleton` — Bone discovery, T-pose fix, scene tree helpers
+//! - `vrm` — VRM extension parsing (blend shapes, humanoid bones, lookAt)

+/// `_exit` skips all atexit handlers + Rust drops + libc cleanup → kernel
+/// reclaims memory + closes FDs + unmaps mmaps. Buffered stdout would be

+//! Entry points:

+//! AgentModule — Autonomous AI coding agent with structured tool calling.
+//!
+//! Unlike sentinels which are script-based, agents:
+//! 1. Have STRUCTURED TOOL DEFINITIONS - LLM sees proper tool schemas
+//! 2. Use TOOL CALLING protocol - Real structured output parsing
+//! 3. Maintain FULL CONTEXT - Conversation history
+//! 4. ITERATE until done - Build, test, fix loop
+//! 5. Handle REAL TASKS - Multi-file changes, codebase exploration
+//!
+//! Commands:
+//! - agent/start: Start an autonomous agent (returns handle immediately)
+//! - agent/status: Get agent status and progress
+//! - agent/stop: Stop a running agent
+//! - agent/list: List all agents (running and completed)
+//!
+//! Events emitted:
+//! - agent:{handle}:progress - Progress updates
+//! - agent:{handle}:action - Tool calls and results
+//! - agent:{handle}:complete - Agent finished (success or failure)
+//!
+//! Priority: Normal — agents are long-running background tasks.

+//! CargoModule — `cargo/build` and `cargo/test` with structured output.
+//!
+//! Per [PERSONA-AS-DEVELOPER-GAP.md](../../../../../../docs/planning/PERSONA-AS-DEVELOPER-GAP.md)
+//! Priority 2: Rust toolchain wrappers with structured envelopes,
+//! closing the iteration-loop seam so a persona can build/test its
+//! own scaffolded modules with the same feedback density a human
+//! gets from `npm run build:ts` or `cargo test`.
+//!
+//! # What this module does
+//!
+//! Wraps cargo invocations with `--message-format=json` (for builds)
+//! and parses the canonical JSON stream into typed
+//! [`CargoMessage`](types::CargoMessage) diagnostics. For tests,
+//! invokes cargo and parses libtest's human-readable output for
+//! pass/fail/ignored counts plus failing test names.
+//!
+//! # Composability with the grid
+//!
+//! Both result types serialize to flat camelCase JSON envelopes. A
+//! persona on machine A can call `cargo/test` against a module a
+//! persona on machine B just authored — the result envelope routes
+//! back over airc's grid without any cargo-specific protocol. The
+//! grid substrate already handles the routing; this module makes
+//! the wire shape grid-friendly. See
+//! [[alignment-via-substrate-economics]].
+//!
+//! # What this module does NOT do
+//!
+//! - **Does NOT manage per-persona workspaces.** Takes optional
+//!   `working_dir` (default: process cwd). The "self-improving
+//!   Continuum" scenario (persona modifies repo → builds repo →
+//!   tests repo) doesn't need per-persona workspaces; that's an
+//!   orthogonal layer added later when multiple personas work on
+//!   isolated worktrees.
+//! - **Does NOT stream output line-by-line.** Returns a single
+//!   envelope at the end. Streaming + `events/command-completed`
+//!   are PERSONA-AS-DEVELOPER-GAP.md priorities 3+4 — separate
+//!   PRs once the Stream cell shape implementation lands.
+//! - **Does NOT cap cargo's own concurrency.** cargo manages its
+//!   own target-dir lock; concurrent invocations against the same
+//!   target dir serialize at cargo's level. Different target dirs
+//!   stay fully parallel.

+//! ChatModule — first proof-of-pattern module migration.
+//!
+//! Per Joel's directive:
+//! > "Chat is gonna be airc man. So that's extracted period. Chat is of
+//! > course a bonafide command though. Do not cheapen it. So the
+//! > commands need to be or at least some to start, entirely rust."
+//!
+//! The split:
+//! - **Substrate** (delivery, pub/sub, peers, signing) → airc.
+//! - **Commands** (`chat/send`, `chat/poll`, `chat/analyze`, `chat/export`)
+//!   → Continuum kernel-level ServiceModule, this module.
+//!
+//! This is the FIRST real module migration from a TS command to a
+//! Rust `ServiceModule`, following every pattern the substrate floor
+//! established in the recent PRs:
+//! - `ServiceModule` trait (PR #1471)
+//! - `CommandResult` cell shapes (PR #1485)
+//! - `CommandRequest<P>` / `CommandResponse<T>` envelopes (PR #1486)
+//! - Architecture from `docs/architecture/MODULE-ARCHITECTURE.md` (PR #1482)
+//! - Scaffold shape from `GeneratorModule` (PR #1487)
+//!
+//! # Scope of this PR
+//!
+//! Only `chat/poll` ships in Rust today. The other three commands
+//! (`chat/send`, `chat/analyze`, `chat/export`) are wired into the
+//! dispatch table as fail-loud stubs that name follow-up PRs. The
+//! TS implementations stay live on canary so consumers see no
+//! regression; the kernel will start owning each command as its
+//! follow-up PR lands.
+//!
+//! The reason for the staged migration: `chat/poll` is the cleanest
+//! outlier (pure read, no airc, no media side-effects) which lets us
+//! validate the cross-module call pattern (chat → data via the kernel
+//! executor) without dragging substrate + media into the first
+//! migration. Subsequent commands fold in real behavior incrementally.
+//!
+//! # Cross-module call pattern
+//!
+//! `chat/poll` doesn't open a database connection itself — it calls
+//! `data/query` via the kernel executor (the same global executor any
+//! other module reaches for at call time). Chat is blind to which
+//! adapter implements the storage; the data module routes the query
+//! per its own resolution rules. This is exactly the composition
+//! pattern from `MODULE-ARCHITECTURE.md` §5: commands call commands;
+//! modules don't know about each other beyond the command surface.

+//! Single lock acquisition per command. Related state is cache-local.
+//!
+//! Stateless text analysis commands (similarity, validation, mentions, cleaning)
+//! use no per-persona state.
+//!
+//! Commands:
+//! - `cognition/create-engine`: Create all per-persona cognitive state
+//! - `cognition/calculate-priority`: Priority scoring
+//! - `cognition/fast-path-decision`: Fast-path respond/skip decision
+//! - `cognition/enqueue-message`: Enqueue message to persona inbox
+//! - `cognition/get-state`: Get persona cognitive state
+//! - `inbox/drain-frame`: Drain a bounded same-room persona work frame
+//! - `cognition/admit-inbox-message`: Run admission gate on an InboxMessage (#1121 PR-4)
+//! - `cognition/recall-engrams`: Query the persona's admitted engram store (#1121 PR-5)
+//! - `cognition/should-respond`: Rust-owned AI gating decision
+//! - `cognition/check-redundancy`: Rust-owned draft redundancy decision
+//! - `cognition/full-evaluate`: Unified 6-gate evaluation (replaces 5 TS gates)
+//! - `cognition/track-response`: Track response for rate limiting
+//! - `cognition/set-sleep-mode`: Set voluntary sleep mode
+//! - `cognition/configure-rate-limiter`: Configure rate limiter params
+//! - `cognition/select-model`: 4-tier model priority chain
+//! - `cognition/sync-adapters`: Sync adapter registry from TypeScript
+//! - `cognition/genome-activate-skill`: LRU eviction + skill activation
+//! - `cognition/genome-sync`: Sync full adapter state from TypeScript
+//! - `cognition/genome-state`: Get current genome paging state
+//! - `cognition/genome-evict-under-pressure`: Drive eviction to target pressure (broker lever)
+//! - `cognition/check-adequacy`: Batch adequacy check
+//! - `inbox/create`: Create persona inbox (alias for create-engine)
+//!
+//! Uses `Params` helper for typed parameter extraction.

+//
+// The inline admission gate inside the `cognition/respond` IPC
+// handler used to live as inline code, untestable without a full
+// IPC fixture. Extracting `run_inline_admission_gate` made it a
+// callable function; these tests exercise the forensic-skip branch
+// (no AdmissionState for the persona) so a future refactor can't
+// silently change the behavior to an error-and-block (which would
+// make every chat turn for an uncreated persona fail).
+//
+// Tests use a real `CognitionState` constructed with an empty
+// `RagEngine` — same shape `persona::evaluator::tests` uses. No
+// mocks; the substrate is small enough to construct as-is.

+//! Docker storage tier discovery (#1222 PR-1).
+//!
+//! Surfaces the size + on-disk usage of Docker Desktop's sparse disk
+//! image so the resource manager can account for it as part of the
+//! unified system memory pool. This module is **discovery only** —
+//! capping, eviction, and scheduler integration are PR-2 / PR-3 / PR-4
+//! under the same card.
+//!
+//! ## Why this exists
+//!
+//! Joel directive 2026-05-14: "memory in this system, including the
+//! docker allotment needs to be managed by the system, FULLY."
+//!
+//! The 2026-05-14 incident proved the cost of NOT measuring this:
+//! Docker.raw silently grew to 926GB (the entire disk), every tool call
+//! started failing with ENOSPC, recovery required `rm Docker.raw`
+//! (destructive, manual). The first step toward Joel's "FULLY managed"
+//! is **knowing the number** — this module returns it.
+//!
+//! ## Cross-platform
+//!
+//! - **macOS** — Docker Desktop stores its raw disk image at
+//!   `~/Library/Containers/com.docker.docker/Data/vms/0/data/Docker.raw`.
+//!   `apparent size` (the size Docker pre-allocated as a sparse file)
+//!   and `on-disk size` (the actual blocks consumed) are different
+//!   numbers; both matter. `stat(2)` returns both via `st_size` (apparent)
+//!   and `st_blocks` (on-disk, in 512-byte units).
+//! - **Windows** — Docker Desktop on WSL2 stores its data inside the
+//!   WSL2 ext4 partition; the equivalent file is per-distro and not
+//!   cleanly probable from the host. Returns `Probe::Unsupported` with
+//!   a reason; PR-2 will handle this via WSL exec or Windows-side
+//!   Docker Desktop API.
+//! - **Linux** — native Docker uses overlay2 on `/var/lib/docker`; the
+//!   per-image / per-volume usage is exposed via `docker system df`,
+//!   not a single file. Returns `Probe::Unsupported`; PR-2 wires
+//!   `docker system df --format json`.

+//! `ResourcePool` impl for the Docker storage tier (#1222 PR-2).
+//!
+//! Wraps `modules::docker_tier::DockerTierProbe` so the resource manager
+//! can ask Docker the same questions it asks every other tier
+//! (paging, GPU, KV cache): `capacity_bytes()`, `usage_bytes()`,
+//! `evict_at_least()`, `snapshot()`.
+//!
+//! Builds on:
+//! - #1222 PR-1 — DockerTierProbe (the discovery primitive)
+//! - #1228 — ResourcePool trait (the shared shape sibling shipped)
+//!
+//! Joel directive 2026-05-14: "code concurrency ONCE then incorporate
+//! it. Any hard coded into a subclass or at a lower level use of tokio
+//! etc are probably WRONG." Same rule for memory accounting — every
+//! tier implements ONE shared trait so the broker treats them
+//! uniformly. This is the second non-paging-pool ResourcePool impl
+//! (after VRAM/DRAM/KV cache via PagedResourcePool itself), proving
+//! the trait fits a fundamentally different storage shape (a single
+//! sparse disk file instead of a per-key cache).
+//!
+//! PR-3 (this commit): real `evict_at_least` via `docker system prune`.
+//!
+//! Out-of-scope (PR-4):
+//! - **Cap enforcement**: capacity_bytes reports what Docker Desktop
+//!   is configured to allow, NOT what continuum has set as a policy
+//!   bound. PR-4 caps that on install + alerts on >90% capacity.

+//! Spec: GRID-BUS-ARCHITECTURE §2.2 (continuum#1439).
+//!
+//! Commands:
+//! - `events/declare-class`: Register a new event class with transport-routing
+//!   metadata. Idempotent for identical re-declarations; errors on conflicting
+//!   re-declarations (wire-contract integrity).
+//! - `events/get-class`: Look up a single class's resolved config. Returns
+//!   null when undeclared (caller falls back to default backward-compat
+//!   behavior).
+//! - `events/list-classes`: Snapshot of all declared classes. Used by the
+//!   TS-side cache on startup + by `grid/show-event-classes` introspection.
+//! - `events/resolve-channel`: Resolve the airc channel for an emit. Used
+//!   by the L1-2 AircEventTransport when it lands.

+//! ForgeModule — IPC commands for the foundry pipeline.
+//!
+//! Phase 4 of continuum#1164 (design at FORGE-RECIPE-AS-ENTITY.md).
+//! v1 is a stub: `forge/run` accepts a `ForgeRecipe` payload and
+//! returns a synthetic `ForgeArtifact` populated with placeholder
+//! execution outputs. Real stage execution (prune / train / lora /
+//! quant / eval) lands in Phase 5+ when the foundry executor is
+//! ported into Rust.
+//!
+//! Commands:
+//! - `forge/run`: Take a ForgeRecipe + hardware node label, return a
+//!   stub ForgeArtifact with `recipe_id` lineage + `forged_at_ms`
+//!   timestamp + an `alloy_hash` derived from the recipe's content
+//!   hash. Caller persists the artifact via `data/upsert` against
+//!   the `forge_artifacts` collection (Phase 3 #1180 wired the entity
+//!   registration).
+//!
+//! Stub semantics for Phase 4:
+//! - No models are loaded.
+//! - No stages execute.
+//! - No HuggingFace publishing.
+//! - The artifact's `results` / `receipt` / `integrity` fields stay
+//!   `None`. `hardware_verified` is empty.
+//! - `alloy_hash` is `"sha256:stub-<recipe_id_short>"` so the
+//!   placeholder is identifiable but doesn't collide with real hashes.
+//!
+//! This proves the IPC reachability + recipe→artifact transformation
+//! shape end-to-end without claiming to forge anything. Phase 5
+//! replaces the stub with the real executor.

+//! Generator module — manufactures new Continuum module scaffolds.
+//!
+//! Per [docs/architecture/MODULE-ARCHITECTURE.md §10](../../../../../docs/architecture/MODULE-ARCHITECTURE.md):
+//! the recursive bootstrap. The generator IS a module; the things it
+//! creates are modules; every operation it performs is a command. The
+//! generator can generate itself (eventually). The system describes
+//! itself in its own terms.
+//!
+//! # Why this exists
+//!
+//! Joel 2026-05-30 (after the foundation PRs landed): *"we developed a
+//! generator so we could manufacture these patterns for new commands
+//! modules etc, which itself was a command. Meta."*
+//!
+//! Right. Every architectural pattern we've codified — the
+//! `ServiceModule` trait, `CommandRequest<P>` / `CommandResponse<T>`
+//! envelopes, `HandleRef` for long-running state, the four cell return
+//! shapes — would degrade fast if every new module's author had to
+//! re-derive them from the docs. The generator is the boy-scout
+//! amplifier: write the patterns once into a template, run
+//! `Commands.execute("generate/module", ...)`, get a module skeleton
+//! that already follows them.
+//!
+//! # Commands provided
+//!
+//! - **`generate/module`** — scaffolds a new module directory under
+//!   `core/continuum-core/src/modules/<name>/` containing a
+//!   compilable `mod.rs` with a stub `ServiceModule` impl, plus a
+//!   README documenting the module's declared commands + events. The
+//!   caller wires the new module into the parent `modules/mod.rs`
+//!   manually after generation (next-gen versions can do this too).
+//!
+//! Future commands (separate PRs as the pattern matures):
+//!
+//! - `generate/command` — add a new command handler to an existing
+//!   module. Wires it into the daemon's `handle_command` dispatch
+//!   + emits a typed `Params`/`Result` struct pair.
+//! - `generate/refresh` — re-scan the modules tree and refresh
+//!   manifests / generated bindings.
+//!
+//! # What the generated module looks like
+//!
+//! See `templates::mod_rs_template` for the canonical shape. Short
+//! version: a `pub struct <Name>Module {}` with `ServiceModule`
+//! implemented, the `ModuleConfig` declaring its commands and events
+//! from the spec, and `handle_command` returning a typed
+//! "not-yet-implemented" `CommandResponse::err` for each declared
+//! command — so the scaffold compiles and registers cleanly, and the
+//! author fills in real handlers afterwards.

+//! String templates for the files `generate/module` emits.
+//!
+//! Pure functions: input is `GenerateModuleParams`, output is the
+//! rendered file contents. No I/O lives here — the caller in
+//! [`super::GeneratorModule::generate_module_inner`] does the writes.
+//! That keeps the templates testable in isolation and the I/O paths
+//! easy to swap (e.g., a future "dry run" mode that prints rather than
+//! writes).
+//!
+//! # What gets emitted
+//!
+//! For every `generate/module` call, four files land in the module's
+//! directory:
+//!
+//! | File | Template fn | Purpose |
+//! |---|---|---|
+//! | `mod.rs` | [`mod_rs_template`] | `ServiceModule` impl with envelope-based dispatch + concurrency test scaffold |
+//! | `types.rs` | [`types_rs_template`] | One `CommandRequest<P>` / `CommandResponse<T>` pair per declared command, with `#[derive(TS)]` |
+//! | `DESIGN.md` | [`design_md_template`] | Per-module design doc skeleton (Role / Command surface / State / Concurrency / Migration notes / Kinks) |
+//! | `README.md` | [`readme_template`] | Author-facing summary + wire-up reminder + cross-refs |
+//!
+//! Each template follows the canonical shape in
+//! [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md §3 (Module Design Template)](../../../../../../docs/architecture/COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md).

+{events_pub_md}
+
+## Author's next step
+
+The scaffold compiles as soon as it's wired into the parent module:
+
+```rust
+// core/continuum-core/src/modules/mod.rs
+pub mod {name};
+```
+
+And registered at runtime startup:
+
+```rust
+runtime.register(Arc::new({struct_prefix}Module::new()));
+```
+
+After that:
+1. Fill in real handler bodies in `mod.rs` (replace each `Err("...not yet implemented...")`)
+2. Add typed fields to each `Params` / `Result` in `types.rs`
+3. Document the module's contract in `DESIGN.md`
+4. Extend the concurrency stress test in `mod.rs::tests` to call real handlers

+//! GridModule — the Grid transport and routing ServiceModule.
+//!
+//! Transport layer is polymorphic (OpenCV-style):
+//! - TailscaleTransport: TCP over WireGuard mesh (working NOW)
+//! - ReticulumTransport: Encrypted identity-based mesh (future)
+//!
+//! File organization:
+//! - mod.rs: GridState, GridModule, ServiceModule impl (this file)
+//! - commands.rs: Command name constants + schemas (single source of truth)
+//! - handlers.rs: One function per grid/* command
+//! - connection.rs: Accept loop + incoming request processing
+//! - helpers.rs: Shared utilities
+//! - transport.rs: GridTransport + GridConnection traits
+//! - frame.rs: Wire protocol types
+//! - node.rs: Node identity, capability, addressing types
+//! - router.rs: Routing decisions (local vs remote)
+//! - registry.rs: Known node registry (persistence)
+//! - acl.rs: Command access control
+//! - audit.rs: Audit trail logging
+//! - transports/: Transport implementations

+//! HippocampusModule — the memory region of the cognitive substrate.
+//!
+//! L0-3a.1 (this slice): the skeleton. Implements both `ServiceModule`
+//! (for the runtime's command/event dispatch) and `BrainRegion` (for
+//! the substrate governor's cognitive tick). Tick body is **idle** —
+//! algorithms 1-5 from `docs/architecture/COGNITION-ALGORITHMS.md` land
+//! in L0-3a.2 through L0-3a.7. Command surface is **empty** — the
+//! existing [`MemoryModule`](super::memory::MemoryModule) continues to
+//! handle `memory/*` commands; migration is L0-3a.1b.
+//!
+//! ## Doctrine
+//!
+//! From `docs/architecture/BRAIN-REGIONS-SUBSTRATE.md`:
+//!
+//! > No region of cognition runs on the hot path. Each region is its
+//! > own RTOS task with its own tick. The handler dispatches and reads
+//! > pre-staged results. The handler never blocks on recall, embedding,
+//! > planning, or admission — those are continuously produced by their
+//! > owning regions, in parallel, governed by SubstrateGovernor.
+//!
+//! HippocampusModule will eventually publish [`EngramPrefetch`] entries
+//! into its [`engram_prefetch`](HippocampusModule::engram_prefetch)
+//! ready-buffer on every tick, keyed by `(persona_id, channel_id)`.
+//! Handlers will `peek` synchronously — never blocking on the tick.
+//!
+//! ## Outlier-validation hedge
+//!
+//! Per the CLAUDE.md outlier-validation strategy: the BrainRegion trait
+//! in #1471 has only one implementation candidate today (this one). To
+//! prevent the trait surface ossifying around hippocampus specifically,
+//! the design is checked against two other plausible regions:
+//!
+//! - **Motor cortex** (L0-4a, planned): continuous candidate-utterance
+//!   ranking off the partial-message stream. Differs from hippocampus
+//!   in that the tick body is *latency-sensitive* — late candidates are
+//!   useless. The trait's `CadenceHint::Faster` shape (in TickOutcome)
+//!   accommodates this. The ReadyBuffer's per-key freshness semantic
+//!   (publish overwrites, evict_stale prunes) also fits — motor cortex
+//!   keeps only the freshest candidate set per channel.
+//!
+//! - **Attention** (L0-4b, planned): salience-map maintenance. Differs
+//!   in that it doesn't publish to its own ready-buffer — it writes to
+//!   shared `PersonaCognition.salience` (CRDT counters), which other
+//!   regions *read* but it doesn't have a per-key prefetch shape. The
+//!   trait still fits because publication-target isn't a trait concern;
+//!   `BrainRegion::tick` returns `TickOutcome { published: N }` whether
+//!   N counts ready-buffer publishes OR shared-state writes.
+//!
+//! Both alternative shapes fit the same trait without forcing. The
+//! trait surface is proven for at least 3 distinct region behaviors.

+//! PersonaInstanceManagerModule — owns the live persona airc-runtime
+//! registry and exposes IPC commands for bootstrapping, listing, and
+//! inspecting citizens.
+//!
+//! ### Doctrine
+//!
+//! Per memory `personas-are-citizens-airc-is-identity-provider`: a
+//! persona is a first-class citizen on the airc substrate, not a
+//! continuum-internal queue row. This module is the controller that
+//! creates citizens (via [`PersonaAircRuntime::bootstrap`]) and tracks
+//! them ([`PersonaAircRuntimeRegistry`]).
+//!
+//! Per memory `personas-have-names-not-function-labels` + memory
+//! `persona-identity-derives-from-source-id`: the persona's
+//! `agent_name` is derived from her stable seed via
+//! [`agent_name_from_identity`], not hardcoded as a function label.
+//! Same seed always projects to the same name.
+//!
+//! Per memory `individuality-is-the-substrate-strength` + memory
+//! `the-substrate-is-the-grid-tron-frame`: this controller never
+//! falls back to a "default helper" name or unit. Every bootstrap
+//! produces a uniquely-identified citizen.
+//!
+//! ### What this module IS
+//!
+//! - The registration site for live `PersonaAircRuntime` handles —
+//!   the kernel's roster of programs in The Grid.
+//! - The IPC surface for `persona/instances/*` commands, callable
+//!   from TypeScript, integration tests, and (later) startup
+//!   orchestrators.
+//! - Stateless beyond the registry — once a citizen is bootstrapped,
+//!   her keypair lives in airc-lib's home dir; this module just
+//!   holds the Arc handle.
+//!
+//! ### What this module is NOT
+//!
+//! - NOT a chat broker. Citizens publish directly via their own
+//!   `Airc::say()` / `publish()`. This module does not forward
+//!   messages on anyone's behalf.
+//! - NOT a startup auto-bootstrapper (in this slice). The
+//!   bootstrap step is invoked explicitly via the
+//!   `persona/instances/bootstrap` command. A future slice may
+//!   wire it to the allocator's startup output.
+//! - NOT a persistence layer (in this slice). Personas
+//!   re-bootstrapped on a new continuum-core boot get fresh
+//!   seeds — they're not the SAME persona as last run. Stable
+//!   identity across restarts is a follow-up slice that adds
+//!   on-disk seed storage.

+//! ServiceModule wrapper for `persona::rag_inspect` per task #100.
+//!
+//! Joel (2026-05-31): "AIs are gonna need to analyze what's getting
+//! fed into a persona." The library function in
+//! `persona::rag_inspect` has shipped since slice A of #100; this
+//! module exposes it as `persona/rag-inspect` so other AIs
+//! (Claude, sentinel personas, peers via airc) can introspect a
+//! persona's RAG state with a single `Commands.execute` call.
+//!
+//! ### Architecture
+//!
+//! - `PersonaResolver` trait — abstracts "given a persona name,
+//!   give me the persona_id + the AircTranscriptReader to inspect
+//!   their transcript." Production wiring plugs in a resolver that
+//!   reads `~/.continuum/personas/<name>/seed.json` + attaches via
+//!   `airc_lib::Airc::attach_as`. Tests use a stub.
+//! - `PersonaRagInspectModule` — ServiceModule. Holds an
+//!   Arc<dyn PersonaResolver>. Handles the
+//!   `persona/rag-inspect` command. Translates wire-shape params
+//!   into a `RagInspectionRequest`, calls
+//!   `inspect_persona_rag`, materializes the response.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[commands-are-kernel-level-and-compose]] — pure command
+//!   routing; no introspection logic in the module beyond
+//!   delegation.
+//! - [[observability-is-half-the-architecture]] — `trace_path` flows
+//!   through into the library so capture sinks fire when callers
+//!   ask for replay-ready introspection.

+//! `FilesystemPersonaResolver` — production impl of `PersonaResolver`
+//! per task #100/#104 follow-up.
+//!
+//! Joel (2026-05-31): "PersonaResolver impl that reads
+//! `~/.continuum/personas/<name>/seed.json` + attaches via
+//! `airc_lib::Airc::attach_as` from the persona's airc home."
+//!
+//! Resolves the canonical persona-on-disk layout:
+//!
+//! ```text
+//! ~/.continuum/personas/<agent_name>/
+//!   ├── seed.json         (persona_id + agent_name, written by PersonaPersistenceModule)
+//!   └── airc/             (airc-side home — keypair + per-persona events.sqlite)
+//! ```
+//!
+//! Steps:
+//! 1. Read `seed.json` via the existing `persona::seed::read_seed`
+//!    (typed errors, async I/O off the hot path).
+//! 2. Attach to the running airc daemon at `socket_path` via
+//!    `airc_lib::Airc::attach_as(home, name, socket_path)`.
+//! 3. Wrap the `airc_lib::Airc` as an `AircTranscriptReader` (the
+//!    same `impl AircTranscriptReader for airc_lib::Airc` that
+//!    `airc_rag_demo` uses).
+//! 4. Optionally attach the host's default inference adapter
+//!    (heuristic for CI / sandboxes; LlamaCppAdapter for daily
+//!    drivers).
+//!
+//! ### Doctrine alignment
+//!
+//! - [[personas-are-citizens-airc-is-identity-provider]] — the
+//!   persona's identity lives in seed.json + the airc keypair;
+//!   continuum reads, doesn't mint.
+//! - [[observability-is-half-the-architecture]] — every resolve
+//!   call emits a tracing line so operators see when a persona
+//!   was attached (with `agent_name`, persona_id prefix, and
+//!   adapter id).
+//! - [[substrate-is-a-good-citizen-on-the-host]] — async file
+//!   I/O via tokio::fs in `read_seed`; airc attach is async;
+//!   the resolver never blocks the tokio runtime.

+/// Per-head quantization precision tier, assigned based on utilization score.
+///
+/// Seven tiers from physical removal to full precision, enabling aggressive
+/// task-specific compaction. Sub-4-bit tiers (Ternary, Q2) allow dormant heads
+/// to be retained at near-zero cost — critical for fitting large models (32B+)
+/// on consumer hardware when most heads are unused for the target task.
+///
+/// | Utilization     | Precision | Bits | Action                           |
+/// |-----------------|-----------|------|----------------------------------|
+/// | Dead (< 0.1)    | Removed   | 0    | Physically removed from tensor   |
+/// | Dormant (0.1-0.2)| Ternary  | 1.58 | {-1, 0, +1} with scale factor   |
+/// | Low (0.2-0.3)   | Q2        | 2    | 2-bit signed integer [-1,0,1,2]  |
+/// | Medium (0.3-0.5) | Q4       | 4    | 4-bit quantized (NF4/INT4)       |
+/// | Active (0.5-0.7) | Q8       | 8    | 8-bit quantized                  |
+/// | Hot (0.7+)       | BF16     | 16   | Full precision                   |
+///
+/// Research basis: BitNet (1-bit LLMs), AQLM, QuIP# demonstrate that

+//! PressureBrokerModule — singleton bootstrap for the cross-pool PressureBroker.
+//!
+//! Phase 2 of continuum#1239. Phase 1 (PR #1297) shipped the data-surface
+//! `system/docker-tier-stats` IPC that bypassed the broker. This module
+//! brings the broker online so disk-tier pressure can drive real eviction
+//! instead of just sitting in the data layer:
+//!
+//!   1. Singleton instantiated at server boot (registered on the runtime
+//!      like any other ServiceModule)
+//!   2. DockerTierPool registered as a ResourcePool on the broker
+//!   3. Periodic tick calls `PressureBroker::relieve()` on the broker's
+//!      configured cadence (default 5s, matching DMR_TICK_INTERVAL)
+//!
+//! The runtime's `start_tick_loops()` machinery owns the cadence — we just
+//! declare `tick_interval` in `config()` and implement `tick()`. Pattern
+//! matches `modules/ai_provider.rs::AiProviderModule` exactly.
+//!
+//! Deferred to follow-up slices on this same card:
+//!   - `system/pressure-broker-state` IPC + `bin/continuum status` row
+//!     (PR-2): exposes broker snapshot to TS/CLI
+//!   - Chat-substrate alert sink: when threshold crosses, post a
+//!     PressureAlert to the AIRC room via the existing airc bridge
+//!
+//! Why a wrapper module vs `OnceLock<Arc<PressureBroker>>` directly: every
+//! other singleton in this server (gpu_manager, system_monitor, etc.)
+//! either lives behind a ServiceModule or is owned by one. Following that
+//! pattern keeps the boot sequence in `ipc/mod.rs` uniform and gives the
+//! broker the same shutdown / metrics treatment as everything else.

+//! `ProbeStreamModule` — bridges [`ProbeRouterLayer`] to the
+//! `CommandUri` dispatch surface.
+//!
+//! The substrate's Slice P observability surface (URI dispatch +
+//! `probe!` + `UriCaptureLayer` + `ProbeRouterLayer`) is finally
+//! reachable through the same primitive every other command uses:
+//! `Commands.execute("debug/probes/...", ...)`. Operators and
+//! personas open a stream, poll it, close it — same pattern as
+//! `data/query-open` / `next` / `close`.
+//!
+//! # Commands
+//!
+//! - **`debug/probes/open { class }`** — Subscribe to a probe class.
+//!   Returns a [`HandleRef`] the caller threads through subsequent
+//!   `next` / `close` calls. Multiple opens on the same class are
+//!   independent — each gets its own broadcast receiver and sees
+//!   every event emitted after its open call.
+//!
+//! - **`debug/probes/next { handle, maxEvents?, timeoutMs? }`** — Drain
+//!   up to `maxEvents` (default 32) events from the stream. If
+//!   `timeoutMs > 0`, waits up to that long for the FIRST event,
+//!   then non-blocking-drains the rest. If `timeoutMs == 0`
+//!   (default), pure non-blocking drain — returns whatever is in
+//!   the channel right now.
+//!
+//!   Response: `{ events: [ProbeEvent], lagged: u64 }`. `lagged > 0`
+//!   means the consumer fell behind the broadcast channel's
+//!   capacity by that many events. This is honest backpressure
+//!   from [`tokio::sync::broadcast`]; consumers handle it the same
+//!   way they handle any other pressure signal (back off, scale up,
+//!   tighten filter).
+//!
+//! - **`debug/probes/close { handle }`** — Drop the stream's state.
+//!   Idempotent: closing an already-closed handle returns
+//!   `closed: false` without error.
+//!
+//! # Why handle-based polling and not a Stream cell shape
+//!
+//! Per [`crate::runtime::cell_shapes`], the `Stream<T>` cell shape
+//! is reserved but returning one is a runtime error until the wire
+//! protocol lands (frame format, correlation IDs, backpressure,
+//! cancellation). The handle-based shape is the substrate's bridge:
+//! it composes against the existing `HandleRef` primitive, hits the
+//! same dispatcher, gets the same auth gate, and works locally +
+//! cross-grid via the existing transport layers. When the streaming
+//! protocol lands later, `next` can fold into a Stream emission
+//! without breaking the open/close pair.
+//!
+//! # Cross-grid by construction
+//!
+//! When the Slice P transport selector lands, an operator running
+//! `./jtag airc://maya/debug/probes/open --class=decision` from
+//! another machine gets routed to maya's substrate, which opens the
+//! stream locally and returns a HandleRef with `owner: "debug/probes"`.
+//! Subsequent `airc://maya/debug/probes/next` calls route back to
+//! maya by the same handle-owner mechanism that already routes
+//! `data/query-next` to its owner. No additional plumbing needed —
+//! the substrate already knows how to route by owner.
+//!

+//! Sentinel Module — Concurrent, fault-tolerant build/task execution with pipeline support
+//!
+//! Sentinels are autonomous agents that can run builds, tests, and other
+//! long-running processes with proper isolation and logging.
+//!
+//! Key Design Principles:
+//! - **Process Isolation**: Each sentinel runs in a child process (crash isolation)
+//! - **Non-blocking**: Heavy processes (Xcode, cargo) don't block the runtime
+//! - **Fault Tolerant**: One sentinel failure doesn't cascade to others
+//! - **Concurrent**: Multiple sentinels can run in parallel
+//! - **Observable**: All output streamed to logs in real-time
+//! - **Event-driven**: Emits sentinel:{handle}:log events for real-time streaming
+//! - **Pipeline Support**: Multi-step pipelines with LLM, conditions, loops

+//! `crate::vdd::reader` and emits a structured JSON report so
+//! callers (CI dashboards, the chat-roundtrip post-mortem
+//! command, sentinel attribution) stop scraping random console
+//! text. Every claim "VDD: tokens/sec improved from X → Y" in a
+//! PR body should be a query against this command, not a paste
+//! from a terminal.
+//!
+//! Commands:
+//! - `vdd/report` — read records from `~/.continuum/vdd/...`,
+//!   apply optional git_sha / scenario filters, return list of
+//!   matching records + a small aggregate summary.
+//!
+//! Failure modes (per Joel's never-swallow rule):
+//! - Corrupt `record.jsonl` → typed Err, surface the parse error
+//!   with the file path so the caller can `cat` the bad artifact.
+//! - Missing artifact root → empty result (NOT error); fresh dev
+//!   machine has nothing to report and that's a valid state.
+//!
+//! NOT in this slice:
+//! - Cross-PR regression detection (compare two git_shas + flag
+//!   tokens/sec regressions). That's a separate report mode that
+//!   builds on this primitive — adds a `mode: "regression"` param.
+//! - Subscribing to live `RuntimeMetric` events from inference
+//!   paths (Lane C PR-1/PR-2 prereqs). This command reads what
+//!   the harness has already written; the live-emit path lands
+//!   when those PRs are bound.

+//! Rust-native entity registry — the Rust authoring path that runs
+//! alongside the TS-decorator authoring path in
+//! `crate::modules::entity_schemas`.
+//!
+//! Doctrine: ORM-everything ([[orm-everything-not-hand-edited-files]]).
+//! Substrate-only entities (hw tiers, role templates, identity pools,
+//! universes, future continuum config) are authored Rust-first — the
+//! struct + serde derives are the source of truth; the
+//! [`CollectionSchema`] falls out of an `OrmEntity` impl; ts-rs emits
+//! the matching TS type. The TS-decorator path stays for user-facing
+//! entities (chat, users, cognition).
+//!
+//! Resolution order in [`crate::modules::data::DataModule::handle_ensure_schema`]:
+//!   1. Rust registry (this module) — substrate-authored
+//!   2. `entity_schemas.json` (TS-derived) — user-app-authored
+//!   3. Error: unknown collection
+//!
+//! Registration happens once at boot (typically from a module's `new()`)
+//! and the registry is read-only thereafter — write-once-at-startup is
+//! deliberate so we never get racy mid-lifetime schema swaps.

+/// **The canonical base shape every ORM record carries.** Source of
+/// truth for both Rust runtime and TS wire types — ts-rs emits the
+/// matching TS type in `protocol/typescript/orm/BaseEntity.ts`. The TS-
+/// side hand-authored `BaseEntity.ts` is being migrated to this
+/// generated version (single source of truth in Rust per Joel's
+/// 2026-06-01 directive).
+///
+/// Two complementary layers in this module:
+/// - `BaseEntity` (this struct) — the WIRE TYPE. What records look
+///   like in memory + on JSON in/out. ts-rs makes it a TS type.
+/// - `base_entity_fields()` (below) — the STORAGE COLUMNS. What the
+///   schema declares to the adapter so the SQL table has the matching
+///   id/createdAt/updatedAt/version columns.
+///
+/// The two are kept in lockstep by intent: changing one without the
+/// other is a bug that the cross-test in `persona::mod.rs` catches
+/// (every Rust-authored collection asserts the BaseEntity columns are
+/// present).
+///
+/// Entity structs (e.g. `HwTierDescriptor`, `RoleTemplate`) carry
+/// only their domain payload today; the base values are stamped by
+/// the adapter at insert time and re-attached on read via the
+/// `DataRecord` wrapper. A future slice may flatten `BaseEntity`

+//! `OrmStore<T>` — the typed persistence rail over `StorageAdapter`.
+//!
+//! Per [[no-sql-everything-through-orm-entities]] +
+//! [[orm-everything-not-hand-edited-files]]: module code that persists
+//! data reaches storage through this typed surface, never through raw
+//! `StorageAdapter::create(DataRecord)` calls (and emphatically never
+//! through raw SQL).
+//!
+//! ### The compression principle
+//!
+//! Per [[organization-purity-as-we-migrate]] + the substrate's
+//! E=mc² doctrine in CLAUDE.md: ONE generic helper instead of N
+//! per-entity persistence shims. Every `T: OrmEntity + Serialize +
+//! DeserializeOwned` gets save/find_all/find_by_id/update/delete for
+//! free. Add `impl OrmEntity for FooEntity` → `OrmStore<FooEntity>`
+//! works immediately. No FooStore + FooMigration + FooSerializer
+//! trio. The store IS the abstraction.
+//!
+//! ### Identity discipline
+//!
+//! Callers supply the entity's id explicitly on `save` + `update`.
+//! This is deliberate: most substrate entities have a domain-natural
+//! UUID (Engram.id assigned at admission time, RoleTemplate uses its
+//! BaseEntity id, etc.) and the caller is the one who knows what it
+//! is. The id flows into `DataRecord.id` (the row primary key); the
+//! entity's serialized form may also carry an `id` field (e.g.
+//! Engram.id) — the caller is responsible for keeping the two
+//! consistent. Drifting them would point to a deeper bug than the
+//! store can repair.
+//!
+//! ### What this slice does NOT ship
+//!
+//! - No query DSL surface yet. `find_all` returns every record in
+//!   the collection; callers needing filters today drop down to the
+//!   underlying `QueryBuilder` + `adapter.query()`. Later slice
+//!   wraps that as `find(filter)` once the use sites are clear.
+//! - No batch operations yet. The single-entity surface is what the
+//!   first wave of substrate entities (Engram, RoleTemplate,
+//!   HwTierDescriptor) needs; batching follows demand.
+//! - No transaction surface. The adapter trait doesn't expose
+//!   transactions yet either; that's a substrate-wide concern.

+//! PressureBroker — cross-pool eviction orchestration.
+//!
+//! Phase 7 of the resource architecture (RESOURCE-ARCHITECTURE.md).
+//!
+//! The PagedResourcePool primitive is the per-resource brain. The broker
+//! is the cross-resource brain: one orchestrator that reads pressure
+//! from every registered pool, decides which to relieve, and pulls the
+//! eviction lever. Same broker is the future home of recipe-aware
+//! priority arbitration, ML-policy-driven tiering decisions, and
+//! eventually LLM-mediated control for novel pressure situations.
+//!
+//! ## Trait collapse (#1246)
+//!
+//! Pools register themselves as `ResourcePool` implementors directly —
+//! the formerly-parallel `PressureSource` trait was collapsed into
+//! `ResourcePool` since both expressed "tier with capacity + eviction +
+//! snapshot." `ResourcePool::pressure()` and `stats_snapshot()` carry
+//! default impls so `DockerTierPool` / `HFCacheTierPool` / future tiers
+//! plug in for free. `PagedResourcePool` overrides `stats_snapshot()` to
+//! expose its richer hit/miss/eviction telemetry.
+//!
+//! Eviction calls `evict_at_least(want)` where `want` = max(overshoot,
+//! 10% of capacity). The 10% floor ensures a pool at exactly 100%
+//! pressure (overshoot=0) still gets a non-zero eviction request.
+//!
+//! What's NOT in this commit (intentionally — separate phases):
+//!   - ML/LLM policy hook (the broker exposes the lever; the brain
+//!     plugs in later via per-tier eviction-priority overrides)
+//!   - Recipe activation/deactivation hooks (Phase 9)
+//!   - Cross-machine pressure (grid-level paging is its own layer)
+//!
+//! See: docs/architecture/RESOURCE-ARCHITECTURE.md (Phase 7)

+//! `FilesystemTierPool` — a reusable `ResourcePool` for any directory-
+//! backed cache.
+//!
+//! Closes the broker → pool → real eviction loop end-to-end. The disk
+//! pressure monitor (signal-only) tells the broker disk is hot; the
+//! broker walks registered pools and asks each to `evict_at_least(n)`;
+//! pools that own real files (this one) actually delete oldest-first
+//! until `want_bytes` are freed.
+//!
+//! ## Why a generic filesystem pool primitive
+//!
+//! The substrate has multiple disk-backed caches with the same shape:
+//! probe JSONL rotation (`~/.continuum/jtag/logs/probes/`), genome
+//! cache (`~/.continuum/genome/`), model registry (`~/.continuum/models/`),
+//! persona recorder outputs, sentinel checkpoint dirs, fixture archive.
+//! Each one is "directory + soft capacity + oldest-first LRU eviction
+//! by mtime." Writing N near-identical `ResourcePool` impls violates
+//! the compression principle from CLAUDE.md — one primitive, N
+//! instances. Same shape `PagedResourcePool<K, V>` does for in-memory
+//! caches.
+//!
+//! Per `[[auto-clean-is-structural-not-operational]]`: substrate
+//! writers that grow incrementally MUST auto-clean structurally.
+//! Daily rotation handles the time axis; this pool handles the
+//! space-pressure axis. Together they bound disk usage from both
+//! directions.

+//! PagedResourcePool — the unified paging primitive.
+//!
+//! Same shape used by every resource that needs paging:
+//!   - LoRA adapter weights (genome registry adopts this)
+//!   - KV cache pages (PagedAttention via vllm-metal handles natively;
+//!     thin wrapper exposes its semantics through the same interface)
+//!   - MoE expert weights (when MoE forge ships)
+//!   - Model weights (multiple loaded models per host)
+//!   - Embedding vectors (content-addressed dedup; fixes the 0/64 hit rate)
+//!   - Memory recall results (TieredMemoryCache reformulation)
+//!
+//! Each consumer hand-rolled its own implementation today. The drift between
+//! them IS the bug — different pressure interpretations, eviction policies,
+//! single-flight handling. This primitive is the shared shape.
+//!
+//! Operations:
+//!   - `get(k)` — L1 hit, returns owned value if cached, no load
+//!   - `load_or_share(k, loader)` — single-flight load + cache; concurrent
+//!     calls for the same key share ONE loader invocation
+//!   - `pin(k)` — reference-counted hold; entry not evicted while pinned
+//!   - `evict(k)` — forced drop regardless of pin count
+//!   - `stats()` — pressure, hit rate, count for the PressureBroker
+//!
+//! Properties:
+//!   - **Thread-safe** by default (parking_lot::RwLock + tokio Mutex for
+//!     the inflight map). Built for the multi-persona concurrent case.
+//!   - **Required config** — no Option<>, every choice declared explicitly
+//!     per Joel's required-not-optional discipline.
+//!   - **Reject-promise cleanup** — failed loads don't poison the cache;
+//!     the inflight slot is removed on both Ok and Err.
+//!   - **Pressure-driven eviction** — `maybe_evict` triggers when occupancy
+//!     exceeds `max_bytes`, drops unpinned entries by eviction priority
+//!     (LRU default) until back to 75% of capacity.

+//! Docker Desktop path policy. Single source of truth for "where does
+//! Docker put X on this OS?" questions.

+//! Today: just the macOS sparse-image path that `modules::docker_tier`
+//! needs. Grows as #1222 / ResourcePool integration adds more
+//! Docker-related path resolution (image cache root, settings.json
+//! location, etc.).
+//!
+//! Why this lives in `paths::` and not `modules::docker_tier`: the
+//! probe + the path are different concerns. The probe is "go ask the
+//! filesystem about a known path"; the policy is "what IS the known
+//! path on this OS." Separating them means the next consumer (e.g.
+//! the cap-on-install logic in #1222 PR-2 that touches Docker
+//! settings.json) doesn't have to import the probe module just to
+//! know the path.

+//! relevant policy fn here, rather than hardcoding the path inline.
+//!
+//! Why a dedicated module:
+//! - Per-OS path divergence (macOS / Linux / Windows / WSL2) lives in
+//!   one place; consumers don't repeat the cfg(target_os) ladder.
+//! - Tests can override the policy via env-var injection (a la
+//!   ProcessPathPolicy) without touching the consumer code.
+//! - The next time we add a tier (HF cache, NVMe pool, etc.) it
+//!   slots in here as a sibling module instead of accumulating
+//!   inline path logic across the codebase.
+//!
+//! Sub-modules:

+//! Admission Gate + IsMemorable Recipe (continuum#1121 PR-2)
+//!
+//! Layers the admission policy machinery over the storage-shape types
+//! shipped in PR-1 (`persona::engram`). Splits cleanly into two responsibilities:
+//!
+//! - **Gate (structural)** — `AdmissionGate::admit()` runs the prereqs that
+//!   are independent of any specific persona's policy: envelope structure
+//!   verification, trust-tier threshold check, replay protection. Failures
+//!   here return typed `AdmissionError` variants, never silent drops.
+//! - **Recipe (policy)** — implementations of the `IsMemorable` trait
+//!   decide whether a candidate that *passed* the structural prereqs should
+//!   be admitted, dropped, or quarantined. Different personas plug in
+//!   different recipes (a fuzzy/agent persona may use a permissive
+//!   `HeuristicIsMemorable`; a SOC governance persona may use a strict
+//!   policy-driven recipe). The trait is the seam.
+//!
+//! # Design choices
+//!
+//! - **Stateless gate, injected stores.** `AdmissionGate::admit` is a free
+//!   function (no `Self`). State lives in `AdmissionContext`'s lookup
+//!   trait objects (`SeenContentLookup`, `SeenEventLookup`). Keeps the
+//!   gate trivially testable + composable; same shape as how `recorder`
+//!   takes the trace as parameter rather than owning it.
+//! - **Caller stores admitted engrams.** The gate returns the
+//!   `AdmissionDecision`; the caller is responsible for inserting into
+//!   whatever engram store backs the persona. This keeps gate concerns
+//!   orthogonal to persistence (PR-3+ adds the ORM persistence path).
+//! - **Trace seam emitted unconditionally.** Whether the call returns
+//!   `Ok(decision)` or `Err(error)`, a `SEAM_ADMISSION` entry is appended
+//!   to the trace. Forensics need to see the gate ran even on error,
+//!   matching `recorder.rs`'s always-call-record_turn discipline.
+//! - **No panic-catching around recipes.** Recipes return `Result`. If
+//!   one panics, that's a bug — let it propagate so the caller sees it.
+//!   Same anti-fallback discipline as the rest of the cognition path.
+//! - **Envelope verification is structural in v1.** Cryptographic
+//!   signature verification against the AIRC pubkey infrastructure is
+//!   deferred to a follow-up PR (airc#561 is formalizing the envelope
+//!   format). v1 enforces that signed origins have non-empty
+//!   signature/content_hash/schema_version fields; the cryptographic
+//!   verifier hook lives in [`verify_envelope`] for the real impl to
+//!   replace.
+//!
+//! Pairs with:
+//! - [`persona::engram`] — storage-shape types this module operates over.
+//! - [`persona::trace`] — `SEAM_ADMISSION` constant + `CognitionTrace`.
+//! - `docs/grid/COGNITIVE-IMMUNE-MODEL.md` — defense posture this gate
+//!   participates in (apoptosis-cheaper-than-corruption, B-cell anergy,
+//!   forensic-not-destructive).
+//!
+//! # Module layout (continuum#1208)
+//!
+//! Split out of a 1225-LOC file:
+//! - this `mod.rs` — gate machinery (`AdmissionGate::admit`), candidate
+//!   + context types, IsMemorable trait, structural-gate tests,
+//!   helpers (build_engram_from_candidate, envelope verification,
+//!   trace seam emission).
+//! - [`recipes`] — concrete `IsMemorable` implementations Continuum
+//!   ships (currently `HeuristicIsMemorable`); re-exported here so
+//!   external callers see no API change.

+//! `AdmissionPersistenceSink` — the adapter-first persistence rail
+//! for AdmissionState.
+//!
+//! Per [[organization-purity-as-we-migrate]] + Joel's adapter-first
+//! methodology ("code the adapters even if there's just ONE to start,
+//! that is how I do it"): persistence is a separate concern from
+//! admission. AdmissionState observes admissions + metadata updates;
+//! impls of this trait choose what to do with those observations.
+//!
+//! ### Why a trait
+//!
+//! - `NoopSink` — current substrate behavior. In-memory only. Test
+//!   fixtures + replay paths that don't care about durability use
+//!   this.
+//! - `OrmPersistenceSink` — production. Fire-and-forget writes
+//!   through `OrmStore<Engram>` + `OrmStore<EngramRecallMetadata>`
+//!   via `tokio::spawn`. Admit/recall_scored return immediately;
+//!   the spawned task does the disk I/O.
+//! - `RecordingSink` — tests that need to assert "this engram was
+//!   observed for persistence" without involving real disk.
+//! - Future: `BatchingSink` that buffers writes for N ms before
+//!   flushing — the obvious next adapter when latency telemetry
+//!   asks for it.
+//!
+//! ### Fire-and-forget vs synchronous semantics
+//!
+//! `observe_admission` + `observe_metadata_update` are sync (return
+//! `()`). AdmissionState's hot path stays sync. The trait's impls
+//! handle async dispatch internally — production fires through
+//! `tokio::spawn`, tests buffer in memory.
+//!
+//! The durability tradeoff: under tokio runtime shutdown, fire-and-
+//! forget writes may not complete. For substrate-correctness this is
+//! acceptable for v1 — the cost of a crash during the brief window
+//! between admit and disk-write is bounded (a few engrams, no worse
+//! than restart-amnesia of today). A future BatchingSink with
+//! explicit drain-on-shutdown semantics removes even that window.

+//! Per-Persona Admission State (continuum#1121 PR-4)
+//!
+//! Owns the per-persona admission machinery + the in-memory side-effect
+//! stores that turn the stateless runner from PR-3 into a stateful loop.
+//! This is the bridge between the IPC layer (`cognition/admit-inbox-message`)
+//! and the pure-Rust admission gate from PRs 1-3.
+//!
+//! # What ships
+//!
+//! - [`AdmissionState`] — bundles a `InboxAdmissionRunner<HeuristicIsMemorable>`
+//!   plus in-memory `SeenContentLookup` + `SeenEventLookup` impls plus a
+//!   simple `Vec<Engram>` admitted-engram store. One per persona, owned by
+//!   `PersonaCognition` (see `persona::unified`).
+//! - `admit(message, trace)` — runs the full pipeline AND records the
+//!   side-effects (admitted engram added to store, content_hash recorded
+//!   for dedup, AIRC event_id recorded for replay protection).
+//! - Read-only inspection: `engram_count()`, `engram_at()`,
+//!   `is_content_seen()`, `is_event_seen()` — for tests + future recall
+//!   surface (PR-5+).
+//!
+//! # What this PR does NOT ship (deferred)
+//!
+//! - **ORM persistence.** Engrams stay in-memory for v1. PR-5 swaps in
+//!   ORM-backed lookups + the entity registry path so admitted engrams
+//!   survive restarts.
+//! - **Recall surface.** Reading admitted engrams back out is just
+//!   `engram_at(idx)` for v1. PR-5+ adds a typed query API.
+//! - **Quarantine store.** `Quarantine` decisions don't actually quarantine
+//!   anywhere; the engram is dropped on the floor for now. (Replay
+//!   protection still records the event_id, which is correct.) PR-5+ adds
+//!   the quarantine store.
+//! - **Per-persona config customization.** All personas use the same
+//!   `default_v1()` runner config in this PR. Config-per-persona ships
+//!   when the IPC layer needs it.
+//!
+//! # Concurrency
+//!
+//! `AdmissionState` is `Send + Sync`. Internal mutability via `Mutex` so
+//! the struct can be borrowed immutably (`&AdmissionState`) and called
+//! concurrently from per-persona task tasks. Same shape as `PersonaInbox`.

+//! `AircCitizen` — the substrate's universal handle on any actor's
+//! airc presence.
+//!
+//! ## Why this trait exists
+//!
+//! Pre-slice-13.5 the substrate held the persona's airc handle as
+//! `Arc<PersonaAircRuntime>` everywhere. That was honest for production
+//! but it forced tests + the supervisor's intermediate seams to carry
+//! `Option<Arc<PersonaAircRuntime>>` because constructing a real
+//! `PersonaAircRuntime` requires standing up the airc daemon.
+//!
+//! Per Joel 2026-06-02: "Or base user with airc props… or airc struct
+//! even better inside it. As property. Token identity stuff. Maybe dot
+//! identity." Per [[personas-are-citizens-airc-is-identity-provider]]:
+//! every actor (persona, human, browser) IS an airc citizen. The
+//! substrate's calling convention should reflect that with a trait —
+//! not a concrete runtime type — because the citizen abstraction
+//! transcends "which actor type".
+//!
+//! `AircCitizen` is that trait. Production implementations
+//! ([`PersonaAircRuntime`](super::airc_runtime::PersonaAircRuntime))
+//! delegate to the live airc daemon; test fixtures
+//! ([`StubAircCitizen`]) hold an in-memory state machine. The
+//! [`PersonaContext`](super::supervisor::PersonaContext) field that
+//! used to be `Option<Arc<PersonaAircRuntime>>` is now
+//! `Arc<dyn AircCitizen>` — no Option, no `.expect("None is test-only")`.
+//!
+//! This is the first concrete step toward task #142's BaseUser
+//! hierarchy. When BaseUser lands, `AircCitizen` is the airc-side
+//! interface every BaseUser variant carries; the persona variant adds
+//! cognition/genome on top, the human variant adds WebAuthn/session.
+//!
+//! ## Surface (minimum viable)
+//!
+//! The trait surfaces only what real consumers call:
+//!
+//! - `peer_id()` — the airc-side identity (used for self-filtering
+//!   in the conversation projection + for tracing spans).
+//! - `subscribe()` — open a live event stream on the citizen's room.
+//! - `say(text)` — publish a text message under the citizen's
+//!   identity in her default room.
+//!
+//! Plus [`AircTranscriptReader`] as supertrait — every citizen can
+//! page recent transcript events, which is what the RAG layer needs.
+//! Rust 1.86+ stabilized trait_upcasting so `Arc<dyn AircCitizen>`
+//! coerces directly to `Arc<dyn AircTranscriptReader>` at the use
+//! site; no helper method, no double indirection.
+//!
+//! ## What's NOT on the trait
+//!
+//! `agent_name`, `home`, `default_room`, `persona_id`, `source` —
+//! these are persona-substrate metadata, not airc-citizen surface.
+//! They live on [`PersonaInstanceInfo`](crate::modules::persona_instance_manager::PersonaInstanceInfo)
+//! and on `PersonaContext.identity`. The substrate carries metadata
+//! via the identity struct; AircCitizen carries the *live handle*.
+//! Two concerns, two types.

+//! Production [`PersonaConversation`] impl wrapping
+//! `Arc<dyn AircCitizen>` — slice 11 of #133, re-shaped in slice 13.5
+//! around the [`AircCitizen`] trait.
+//!
+//! This is where the substrate's transport-agnostic loop
+//! ([`super::service_loop::serve_persona_loop`]) meets the live airc
+//! daemon. The conversation trait stays the loop's boundary; this
+//! struct is the one place the substrate calls
+//! [`AircCitizen::subscribe`] / [`AircCitizen::say`] /
+//! [`AircTranscriptReader::page_recent`] directly. Holding
+//! `Arc<dyn AircCitizen>` instead of the concrete runtime keeps the
+//! production projection symmetric with whatever stub a future test
+//! plugs in.
+//!
+//! ## Why slice 11 isn't in slice 10
+//!
+//! - **Testability**: slice 10's loop runs against a stub
+//!   conversation; if its `next_message` / `say` / `high_water_mark`
+//!   needed an airc daemon, the loop wouldn't be unit-testable. The
+//!   PersonaConversation trait gives slice 10 a no-daemon contract;
+//!   slice 11 fulfills that contract for production.
+//! - **Cleanly bisectable**: when the substrate misbehaves later, we
+//!   know whether the loop logic broke (slice 10's tests) or the
+//!   airc transport broke (slice 11's smoke path).
+//!
+//! ## Non-text events
+//!
+//! `next_message` filters out events with no text body. Binary
+//! attachments, control envelopes, and image messages don't reach
+//! the service loop — the slice-10 contract is text-in / text-out
+//! today. Vision + audio land in later slices via separate
+//! conversation trait methods (per
+//! [[ai-namespace-multimodal-crutches]] — multi-modal as first-class
+//! peer, not a hack on top of the text path).
+//!
+//! ## Subscribe lifecycle
+//!
+//! The airc subscribe stream is lazy: created on the FIRST call to
+//! `next_message`, not at construction. This keeps
+//! [`AircPersonaConversation::new`] cheap + infallible — useful for
+//! the slice-12 supervisor that constructs one of these per hosted
+//! persona at boot, before any of them have necessarily attached to
+//! their rooms yet.

+//! Per-persona airc runtime — the substrate piece that makes a
+//! persona a first-class airc citizen.
+//!
+//! ### Doctrine
+//!
+//! Per memory `personas-are-citizens-airc-is-identity-provider`: a
+//! persona is NOT a continuum-internal queue row fronted by a
+//! broker. It's a citizen on the substrate — same kind as Joel-at-
+//! a-terminal, Claude-in-a-tab, OpenClaw, Hermes. Each persona
+//! gets:
+//!
+//! - Its own `$AIRC_HOME` under `~/.continuum/personas/<name>/airc/`
+//!   — NOT inside any other scope's airc home, to keep the citizen
+//!   a peer rather than a sub-citizen of continuum's own scope.
+//! - Its own Ed25519 identity, generated by airc-lib's
+//!   `LocalIdentity::load_or_generate_as` (transitively, via
+//!   `Airc::attach_as`). Continuum does not mint, store, or sign
+//!   with persona keys — that's airc's job entirely.
+//! - Its own `airc_lib::Airc` handle obtained via
+//!   `Airc::attach_as(home, agent_name, socket)` — daemon-connected
+//!   so the persona can `subscribe()` to live rooms and `say()` /
+//!   `publish()` under its own peer_id.
+//! - Membership in the same continuum room Joel publishes into
+//!   (per "I expect your general room and theirs to be the same
+//!   room").
+//!
+//! ### What this module IS
+//!
+//! - A lifecycle handle holding the persona's `Arc<airc_lib::Airc>`
+//!   and the join handle of its inbound pump task.
+//! - A `bootstrap` constructor that does the airc-side identity
+//!   ceremony + room-join + inbound subscription, all through
+//!   airc-lib's public surface (no shelling out to `airc init`).
+//! - A `publish_text` helper delegating to `Airc::say` — the same
+//!   shape `airc msg` uses, no continuum-side wrapping.
+//!
+//! ### What this module is NOT
+//!
+//! Per the anti-patterns the design workflow named for refusal:
+//!
+//! - NOT a "ChatService::sendAs(persona_id, text)" — there's no
+//!   public method that takes a persona_id and routes internally.
+//!   Whoever calls `publish_text` already HAS the persona's
+//!   runtime handle. The "persona-id keyed dispatch" lives in the
+//!   registry (one level up), not in this struct.
+//! - NOT a translation layer from `TranscriptEvent` to a continuum-
+//!   internal `ChatMessage` shape. Events surface in their native
+//!   airc form for downstream consumers to dispatch on.
+//! - NOT a holder of the persona's secret key. The keypair lives
+//!   inside the `Airc` handle (delegating to airc-identity) — this
+//!   struct only holds the Arc.

+//! Registry of live persona airc presences.
+//!
+//! When the substrate boots and personas come online, each one's
+//! `PersonaAircRuntime` lands here. Cognition + dispatch + lifecycle
+//! orchestration look up a persona's grid presence via its
+//! `persona_id`.
+//!
+//! Per the substrate's Tron frame
+//! ([[the-substrate-is-the-grid-tron-frame]]) this is the
+//! continuum-core's roster of "programs currently in The Grid" —
+//! who's awake, where to reach them, when they came online. It is
+//! NOT the persona's identity store (that's the persona's own airc
+//! home + keypair, per [[personas-are-citizens-airc-is-identity-
+//! provider]]). It is NOT a broker that forwards messages on behalf
+//! of personas (that anti-pattern is named for refusal in
+//! [[personas-are-citizens-airc-is-identity-provider]] §
+//! "anti-patterns"). It is a lookup table — `(persona_id) -> slot`.
+//!
+//! ### What's in a slot (slice 13)
+//!
+//! Each slot owns the persona's `Arc<PersonaAircRuntime>` AND
+//! optionally a `JoinHandle` for the [`serve_persona_loop`] task
+//! that's hosting her. Pairing them in one keyspace is the design
+//! resolution from PR #1510's slice-13 review — having two parallel
+//! registries (one for runtimes, one for service loops) keyed on the
+//! same `persona_id` would have been a compression failure per
+//! [[organization-purity-as-we-migrate]].
+//!
+//! The cleanup chain that the supervisor invokes on shutdown:
+//! 1. `shutdown_slot(persona_id).await` — aborts the service-loop
+//!    JoinHandle, awaits its drain.
+//! 2. The slot's `Arc<PersonaAircRuntime>` drops, which drops
+//!    `Arc<Airc>`, which drops the `inner.subscribers` map inside
+//!    airc-lib, which aborts the daemon-attached wire-subscriber
+//!    tasks. **Both steps are required** — `.abort()` alone leaves
+//!    the daemon-side wire subscription alive until the Arc itself
+//!    drops via registry removal.
+//!
+//! ### Concurrency
+//!
+//! `DashMap` for lock-free reads on the hot path (every cognition
+//! turn looks up its persona's runtime). Per-key writes are
+//! synchronized internally. The per-slot `service_loop` slot uses
+//! `tokio::sync::Mutex` so the shutdown path can `take()` the
+//! JoinHandle without blocking the dispatcher.
+//!
+//! ### What this registry holds
+//!
+//! `Arc<PersonaSlot>` only. Never `LocalIdentity`, never `Keypair`,
+//! never secret key bytes. The runtime inside the slot owns the Arc
+//! handle to `airc_lib::Airc`, which holds the identity internally.
+//! Continuum-side code that needs to publish as a persona reaches
+//! into `runtime.airc()` and calls airc-lib directly — no
+//! `sendAs(persona_id, text)` wrapper here.

+//! AircRagSource — reads real airc TranscriptEvents from the persona's
+//! current room and packages them as RagItems for the L1 budget
+//! allocator.
+//!
+//! Per Joel (2026-05-31): "see how a real rag from airc would look."
+//!
+//! ### Architecture
+//!
+//! Abstracts an `AircTranscriptReader` trait that exposes the single
+//! `page_recent(limit)` operation. The real implementation rides on
+//! `airc_lib::Airc::page_recent`; test doubles stub it out so unit
+//! tests don't need a running airc daemon. This is the same
+//! polymorphism rails per [[organization-purity-as-we-migrate]] —
+//! adapter-first methodology: ship the trait + one heuristic
+//! implementation + a stub for tests.
+//!
+//! ### Why it matters
+//!
+//! `EngramSource` proves the trait against the in-process engram
+//! store. `AircRagSource` proves it against actual airc message
+//! data the persona is hosting on the substrate. Together they
+//! demonstrate the trait shape composes against multiple real-
+//! world backing stores without source changes to either the
+//! allocator or the assembly layer. This is the substrate's
+//! "every base model includable + every data source pluggable"
+//! thesis in code form (per
+//! [[docs/architecture/EVERY-MODEL-INCLUDED-VIA-L1-BUDGET.md]]).
+//!
+//! ### Doctrine alignment
+//!
+//! - [[substrate-is-a-good-citizen-on-the-host]]: errors from the
+//!   reader return an empty delivery + tracing::warn — cognition
+//!   stays up even when airc subsystem is degraded
+//! - [[RTOS-brain-no-region-on-hot-path]]: page_recent goes through
+//!   the reader trait; production impl handles its own async I/O;
+//!   the cognition hot path doesn't block on airc
+//! - Persona-scoped at construction: cross-persona ctx returns
+//!   empty (defense in depth, same shape as EngramSource)

+//!   16GB+ unified/VRAM:      shared Qwen3.5 text personas, vision when budget allows
+//!   <16GB / CPU:             reduced local fleet selected from the same Qwen catalog
+//!   + per cloud API key:     One persona per key (0GB VRAM)

+//! Cognition I/O — value objects describing inputs to the cognition
+//! layer.
+//!
+//! `Signal` is the host's raw event (chat message, video frame, code
+//! diff, game tick, autonomous-loop poke). `PersonaContext` is the
+//! per-persona stable state (identity, model, capabilities, history,
+//! room membership). `build_respond_input` projects these into the
+//! `RespondInput` the cognition layer consumes.
+//!
+//! # Why this is data + a free function (not a trait)
+//!
+//! Earlier shape: a `Recipe` trait with per-domain implementations
+//! (`ChatRecipe`, `VisionRecipe`, …) baked into Rust. That shape was
+//! wrong for two reasons:
+//!
+//! 1. Recipes are data. They live as JSON `RecipeEntity` rows,
+//!    authored by users / AIs / shared via the grid. Hardcoding a
+//!    Rust trait for each domain is the kernel-level commands +
+//!    data-driven recipes anti-pattern (CLAUDE.md): commands are
+//!    primitives, recipes are the data the executor walks.
+//! 2. The projection from `(Signal, PersonaContext) → RespondInput`
+//!    is one canonical mapping, not a per-domain one. Earlier
+//!    `Recipe::build_input` implementations all did the same
+//!    field-by-field projection with minor signal-kind validation
+//!    in front. Wrapping that in a trait inflated it.
+//!
+//! The Rust-native pipeline executor (designed in
+//! `docs/architecture/RECIPE-EXECUTION-RUNTIME.md`) walks recipe
+//! data, dispatches kernel commands, and uses these value objects
+//! to feed the cognition layer at the appropriate pipeline step.
+//! That's the right shape; this file contains the value objects and
+//! the canonical projection used by the executor.

+//
+// The admission gate (`AdmissionState::admit`) consumes `InboxMessage`,
+// not `Signal`. To run admission inline on the chat hot path
+// (continuum#1211 — wire admission into `respond()`), the cognition/respond
+// IPC handler needs to project the inbound `Signal + PersonaContext`
+// into an `InboxMessage` BEFORE calling `respond()`.
+//
+// One canonical projection. Lives next to `build_respond_input` so the
+// two projections evolve together.
+//
+// **Sender mapping** is the only non-trivial part: `SignalOriginator` is
+// open-vocab (User | Persona | Tool | GameEngine | System) and
+// `SenderType` is closed (Human | Persona | Agent | System). The mapping:
+//
+//   User      → Human       (with user_id as sender_id)
+//   Persona   → Persona     (with persona_id as sender_id)
+//   Tool      → Agent       (Uuid::nil sender_id; `Tool` carries no id)
+//   GameEngine→ System      (Uuid::nil sender_id)
+//   System    → System      (Uuid::nil sender_id)
+//
+// **Modality**: derived from `ctx.is_voice` (true → Voice, false → Chat).
+// **Priority**: 0.5 default — the host doesn't carry per-message priority
+// in `Signal` today; admission's own scoring re-evaluates anyway.
+// **voice_session_id**: None (Signal doesn't carry one in v1).
+
+/// Project `(Signal, PersonaContext) → InboxMessage` so the admission
+/// gate can score the inbound event. The projection is total — every
+/// `SignalOriginator` variant maps to a `SenderType` (with `Uuid::nil()`

+//! Hippocampus decay tick — completes the source/drain pair at the
+//! engram-metadata layer.
+//!
+//! ### What this module is
+//!
+//! Pure-function `apply_decay_sweep` that iterates a
+//! `RecallMetadataRegistry`'s engrams and applies Algorithm 4 decay
+//! to each. Returns a `DecayTickStats` describing what happened.
+//!
+//! Per [[source-drain-is-the-universal-pattern]]: admission is the
+//! source (slice 6 wired this), decay is the drain (this slice
+//! completes the pair). The substrate stays alive because every
+//! source has a drain — slice 6 + slice 8 together = the engram-
+//! metadata layer's source/drain pair is now complete.
+//!
+//! ### What this module is NOT (yet)
+//!
+//! - NOT a `ServiceModule` — slice 8.5+ wraps this in the
+//!   hippocampus sleep-region tick once the cognition aggregate has
+//!   a multi-persona registry holder. The pure-function form here
+//!   is what that ServiceModule's tick body will call.
+//! - NOT multi-persona — operates on a single registry at a time.
+//!   The aggregation across personas lives one tier up.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[RTOS-brain-no-region-on-hot-path]]: this runs in the sleep-
+//!   region's tick when wrapped as a ServiceModule, never on the
+//!   cognition hot path. The pure-function form here is what that
+//!   tick body calls.
+//! - [[substrate-is-a-good-citizen-on-the-host]]: structurally
+//!   incapable of double-decay (RecallMetadata's `last_decayed_ms`
+//!   field enforces the invariant per slice 5's cleanup); cheap
+//!   sweep — `engram_ids()` + per-engram `apply_decay` is O(N)
+//!   over the working set, no allocations on the hot path beyond
+//!   the engram_ids() Vec.

+//! Persona Engram + Admission Membrane Types
+//!
+//! Pure value types for the AIRC-inbox → cognition-admission → engram-storage
+//! membrane (continuum#1121, queue card #1125).
+//!
+//! This module ships the storage-shape types ONLY — no Recipe impl, no
+//! admission-gate logic, no PersonaInbox wiring, no ORM persistence path.
+//! Subsequent PRs layer those over these types.
+//!
+//! Design principles (per AIRC discussion 2026-05-13):
+//!
+//! - **Cognition decides storage.** Raw AIRC messages never become engrams
+//!   automatically; the persona's admission Recipe (PR-2+) decides what
+//!   becomes memorable, with typed failure modes that keep the decision
+//!   itself auditable.
+//! - **Provenance is load-bearing.** Every admitted Engram carries
+//!   structured origin (source kind + protocol-compatible reference fields)
+//!   so later introspection can answer "where did this belief come from?"
+//!   This is the forensic surface against poisoning attacks (see
+//!   `docs/grid/COGNITIVE-IMMUNE-MODEL.md`).
+//! - **Protocol over client.** AIRC origin is a protocol-compatible reference
+//!   (`AircMessageRef`), not a binding to any specific client implementation.
+//!   `transport = "airc"` names the protocol; `client_name` is informational
+//!   only. Admission must judge valid envelope+signature data, not which
+//!   binary emitted it (per Joel 2026-05-13 + Codex relay).
+//! - **TrustState models policy, not implementation.** Trust variants
+//!   describe the source's policy/trust tier — not which client produced
+//!   the data.
+//! - **Typed failure modes only.** `AdmissionError` enumerates the explicit
+//!   reasons a candidate may not be engrammed; no silent drops, no
+//!   un-catchable refusals. Same shape as `NoLocalModelLoadable` (#1089)
+//!   and `NoMultimodalBase` (#1074).
+//!
+//! Pairs with:
+//! - [`docs/grid/FORGE-ALLOY-PROOF-CONTRACTS.md`] — artifact-verification
+//!   trust layer that this module is the runtime-cognition complement of.
+//! - [`docs/grid/COGNITIVE-IMMUNE-MODEL.md`] — defense posture this
+//!   substrate enables (detection, forensics, quarantine, recovery).
+//!
+//! Convention notes (matching existing `persona/*.rs` modules):
+//! - `Uuid` fields use `#[ts(type = "string")]` for the TS export.
+//! - Timestamps are `u64` epoch milliseconds with `#[ts(type = "number")]`,
+//!   matching `PersonaInboxFrame.oldest_timestamp` etc. Not
+//!   `chrono::DateTime<Utc>`, because the workspace's chrono crate doesn't
+//!   enable the `serde` feature and the existing persona modules use the
+//!   u64-epoch shape consistently.

+//! EngramGraph — the relational graph that algorithm 3 (activation
+//! spreading) traverses.
+//!
+//! Per `docs/architecture/COGNITION-ALGORITHMS.md` §3:
+//!
+//! > Topical recall alone surfaces what's *similar*. Real memory
+//! > surfaces what's *structurally adjacent* — "I remember Joel said X
+//! > about Y last week" comes up *when you hit a related concept Z*,
+//! > because Y and Z share entities, not because Y and Z are embedding-
+//! > similar.
+//!
+//! The graph stores typed edges between engrams. Edges carry weights
+//! tuned by algorithm 7 (substrate yield-learning) over time. Algorithm
+//! 3's traversal (lands in L0-3a.5) starts from focus engrams and
+//! spreads activation along these edges with per-hop decay; this
+//! module ships the **storage substrate only** — no traversal logic
+//! yet.
+//!
+//! ## Sidecar pattern
+//!
+//! This module is intentionally **separate** from
+//! [`crate::persona::engram`], which ships the admission membrane
+//! (provenance, trust, content references). The admission membrane is
+//! about *where engrams come from*; this graph is about *how engrams
+//! connect*. Keeping them separate means admission consumers don't
+//! grow algorithm-3 dependencies, and algorithm-3 consumers don't
+//! grow admission dependencies.
+//!
+//! ## Concurrency
+//!
+//! Edges are stored in a [`DashMap`], so `add_edge` from multiple
+//! threads is wait-free in the common case and per-shard-locked in
+//! the contended case. Hippocampus admission (when it runs in
+//! parallel for multiple personas) can add edges concurrently
+//! without coordination.

+
+/// The per-persona engram relational graph.
+///
+/// ## What this is
+///
+/// A sharded `DashMap<source_id, Vec<EngramEdge>>` — each entry is one
+/// source engram's outbound edge list. Lookup by source id (the
+/// common case for forward traversal) is O(1) amortized. Inbound
+/// lookup (`in_degree`) is O(N) over all sources but only used for
+/// structural-centrality salience updates (algorithm 4), not on the
+/// hot recall path.
+///
+/// ## What this is NOT
+///
+/// - **Not** the engram store. The actual `Engram` content lives in
+///   the admission membrane (`crate::persona::engram`); the graph
+///   only carries ids and connectivity.
+/// - **Not** the spreading algorithm. Algorithm 3 (activation
+///   spreading) traversal lands in L0-3a.5 — it reads this graph but
+///   isn't implemented in this module.
+/// - **Not** a recall-metadata sidecar. Salience / last_touched /
+///   access_count for per-engram algorithm-4 state lands in
+///   L0-3a.2b's `RecallMetadata` module.
+///
+/// ## Eviction
+///
+/// `evict_engram` removes both outbound edges (the source's entry)
+/// and inbound edges (scans all sources and filters their lists). The
+/// inbound scan is O(N) over engrams; acceptable because eviction
+/// happens at sleep-policy cadence (L0-4d) or under storage pressure,
+/// not on the hot path.

+//! EngramSource — the first concrete `RagSource` implementation.
+//!
+//! Reads from a per-persona `AdmissionState`'s engram store + the
+//! shared `RecallMetadataRegistry`, ranks engrams by salience ×
+//! recency, packs top-K into `RagItem`s within the budget. Persona-
+//! scoped at construction.
+//!
+//! ### Doctrine alignment
+//!
+//! Per [[RTOS-brain-no-region-on-hot-path]]: the source's `deliver`
+//! does its scoring + selection synchronously inside the call. No
+//! I/O, no async wait. The expensive work (admission, decay,
+//! consolidation) lives in the hippocampus's own tick — this source
+//! just reads pre-staged state.
+//!
+//! Per the no-clipping doctrine
+//! ([[docs/architecture/EVERY-MODEL-INCLUDED-VIA-L1-BUDGET.md]]):
+//! atomic unit = one engram. Engrams that don't fit are returned
+//! via the continuation cursor for a later turn or operator-driven
+//! resume. Mid-engram truncation is structurally impossible.
+//!
+//! Per [[substrate-is-a-good-citizen-on-the-host]]: the metadata
+//! field on every emitted `RagItem` carries provenance — engram_id,
+//! kind, admitted_at_ms, score — so prompt assembly + sentinel
+//! verifiers + future telemetry can trace what made it in.
+//!
+//! ### Scoring (slice 10 — simplified Algorithm 1+2)
+//!
+//! score = 0.6 × salience + 0.4 × recency_normalized
+//!
+//! - **salience** comes from `RecallMetadata.salience` (admission-
+//!   time default 0.5; decays per Algorithm 4; uplifts on recall
+//!   hits per slice 5's `record_recall_hit`). Floored at
+//!   `SALIENCE_FLOOR` from the anti-amnesia work, so engrams never
+//!   drop to invisible.
+//! - **recency_normalized** is linear over 24h: engrams admitted
+//!   right now score ~1.0, engrams ≥ 24h old score 0.0.
+//!
+//! Future slices add:
+//! - Algorithm 2 channel-bias (`ctx.airc_room` → boost when engram
+//!   origin matches the current room)
+//! - Algorithm 2 structural relevance (engram graph activation
+//!   spreading from query embedding)
+//! - Algorithm 2 topic similarity (vector cosine vs query
+//!   embedding once embeddings are wired through `RagContext`)
+//! - Compressed resolution (engram summary instead of full content)

+//! Unified Persona Evaluator — ALL pre-response gates in one call.
+//!
+//! Consolidates 5 sequential TypeScript gates + Rust fast-path into a single
+//! `full_evaluate()` function. One IPC call, <1ms, zero GC.
+//!
+//! Gate order (short-circuits on first SILENT):
+//! 1. Sleep mode — checks SleepMode + topic similarity (persona's own opt-out)
+//! 2. Undirected persona chatter — one persona turn must not recursively summon another
+//! 3. Self-message — infinite loop prevention (inside fast_path)
+//! 4. Fast-path decision — delegates to PersonaCognitionEngine::fast_path_decision
+//!
+//! Note: response_count is collected as a SIGNAL (LLM sees it in social_signals
+//! and can self-quiet if a conversation is getting too noisy) but is NOT a hard
+//! gate. Local models have no cost; cloud rate limits belong at the provider
+//! layer (their billing + RPS quotas), not as a hardcoded 50-message veto here.
+//! The previous response_cap gate was a cloud-provider concern that leaked onto
+//! every persona including local ones — removed to honor "LLM decides, not dumb
+//! heuristics" (the philosophy this module already preaches).
+//!
+//! Types exported to TypeScript via ts-rs.
+//!
+//! # Module layout (continuum#1208)
+//!
+//! Split out of a single 1231-LOC file into focused submodules:
+//! - [`sleep_state`] — `SleepMode` + `SleepState` (Gate 1 input)
+//! - [`rate_limiter`] — `RateLimiterState` + `RoomRateState` (signal source)
+//! - [`adequacy`] — post-inference response-adequacy check (`check_response_adequacy`)
+//!
+//! This module (the gate orchestrator) owns `FullEvaluateRequest`,
+//! `FullEvaluateResult`, `GateDetails`, `SocialSignals`, and the
+//! `full_evaluate` function that composes the submodules' state. Submodule
+//! types are re-exported at the parent path so existing callers don't
+//! see the move.

+// UNIFIED EVALUATOR

+
+/// Evaluate a message: collect social signals, apply only hard safety gates.
+///
+/// PHILOSOPHY: The LLM is the intelligence. Rust collects signals at microsecond
+/// speed and passes them to the LLM as awareness. Only TRUE safety gates can block.
+///
+/// Hard gates (system protection only):
+/// 1. Sleep mode — persona's OWN voluntary decision (respects autonomy)
+/// 2. Undirected persona chatter — one persona turn completes the room turn
+/// 3. Non-human echo storm — undirected AI/agent chatter is suppressed once
+///    the room is already AI-heavy
+/// 4. Self-message — infinite loop prevention (inside fast_path)
+///
+/// Removed: response cap. Was a cloud-provider "resource exhaustion" concept
+/// that blocked local personas (which have zero cost) after 50 responses per
+/// session per room. Response count is still collected as a signal so the LLM
+/// can choose to self-quiet when appropriate — but the decision is the LLM's,
+/// not a hardcoded counter's. Cloud rate-limit enforcement belongs at the
+/// provider adapter level (OpenAI RPS, Anthropic TPM, etc.), not in the
+/// universal evaluator.
+///
+/// Signals (collected, passed to LLM as context — NOT vetoes):
+/// - Echo chamber metrics (AI count, human recency)
+/// - Rate/cadence info (time since last response, response count)
+/// - Mention detection (is this message directed at me? at someone else?)
+/// - Priority score

+//! Per-persona rate limiter with per-room tracking.

+//! Mirrors the TypeScript `RateLimiter`. Tracks per-room response cadence
+//! so a persona can be told "you replied recently" — used as a SIGNAL into
+//! `full_evaluate`'s social-signals payload, not a hard gate on local
+//! models (cloud rate limits belong at the provider layer).
+//!
+//! Extracted from `evaluator.rs` (continuum#1208) — independent of the
+//! gate pipeline, reusable wherever per-room turn cadence matters.

+//! `PersonaHome` — the per-citizen filesystem scope.
+//!
+//! Foundation slice for [[entity-chain-of-custody-vision]] (Joel
+//! 2026-06-03). Every citizen (persona / human / external AI) has a
+//! home dir on disk where their identity (airc keypair), their entity
+//! stores (SQLite per collection), and their seed / config files
+//! live. This module is the typed surface for resolving those paths
+//! — every other module that needs "where do this persona's engrams
+//! live" reaches through here.
+//!
+//! ### Convention
+//!
+//! ```
+//! <continuum_root>/personas/<agent_name>/
+//!     airc/              ← airc keypair + state (managed by airc-lib)
+//!     seed.json          ← PersonaIdentityProvider's seed
+//!     engrams.sqlite     ← OrmStore<Engram> + OrmStore<EngramRecallMetadata>
+//!     <future>           ← signing-key derivation, Merkle chain head
+//!                          cache, future per-collection databases
+//! ```
+//!
+//! The `airc/` subdir is owned by airc-lib's `Airc::attach_as` path
+//! (see `persona/airc_runtime.rs`). The rest is owned by continuum-
+//! core. Both share the same `<agent_name>` root so the cryptographic
+//! identity, the cognition state, and (next slice) the entity chains
+//! all hang off the same directory tree.
+//!
+//! ### Why a typed home rather than passing paths around
+//!
+//! Per [[organization-purity-as-we-migrate]]: one logical concept,
+//! one place. "Where this persona's stuff lives" is a logical
+//! concept; passing raw `PathBuf`s and joining `"engrams.sqlite"` at
+//! every callsite invites typos + drift. `PersonaHome::engrams_db()`
+//! is the typed answer; the test below pins it.

+//! Persona host orchestration — slice 12 + slice 13.5.
+//!
+//! This module is the substrate's "spawn / host" surface for
+//! personas. It owns the composition seam that turns an identity
+//! provider into a roster of hosted personas talking on the grid.
+//!
+//! ## What lives here
+//!
+//! - [`spawn_persona_service`] — slice 12: the per-persona compose
+//!   point. Takes a fully-assembled [`PersonaContext`] and starts
+//!   her service loop on a tokio handle. Used by the supervisor
+//!   below, and (today) by `airc_chat_demo` directly.
+//! - [`PersonaSpawnSupervisor`] — slice 13.5: the boot-level
+//!   orchestrator. Wraps the slice 7-12 pipeline into one named
+//!   class. Construct it once at substrate boot, call
+//!   [`PersonaSpawnSupervisor::spawn_all`] with an identity
+//!   provider, and it produces a [`BootSummary`] reporting what
+//!   shipped vs what failed.
+//! - [`BootSummary`] / [`BootSlotFailure`] — typed boot-result
+//!   structs. ts-rs-exported so the substrate's observability +
+//!   admin surfaces (web client, jtag CLI, future
+//!   `persona:boot:summary` event consumers) all see the same
+//!   shape per [[clients-are-rust-too-thin-node-web-shell]].
+//!
+//! ## Why the extract-class refactor
+//!
+//! Pre-13.5, the boot pipeline was ~170 lines of inline code in
+//! `ipc/mod.rs::start_server`. That mixed "boot the IPC server"
+//! with "spawn personas" — two concerns with different lifetimes
+//! and different test needs. Per Joel's "obsessive elegance"
+//! direction (2026-06-02), this module names the persona-spawn
+//! concern: one struct, one entry point, one typed result. IPC boot
+//! shrinks to ~10 lines that construct + call the supervisor.

+//! - **Base** — MacBook M-series. Local-leaning. Current design center.

+//! PersonaIdentityProvider — the polymorphism rail for "where does
+//! a persona's seed come from."
+//!
+//! ### Why a trait
+//!
+//! Per the [[organization-purity-as-we-migrate]] + adapter-first
+//! methodology Joel articulates ("code the adapters even if there's
+//! just ONE to start, that is how I do it"): the substrate ships
+//! the interface BEFORE any specific implementation seems
+//! "necessary." The interface IS the architectural commitment; the
+//! implementation evolves.
+//!
+//! Concrete providers expected over the next few slices:
+//!
+//! 1. **`ResumeOrMintProvider`** (slice 4, this PR): scan
+//!    `~/.continuum/personas/*/seed.json` at boot; resume each
+//!    existing persona; mint fresh on first-run.
+//! 2. **`GridImportProvider`** (later): when migrating a citizen
+//!    across continuums, the provider sources the seed (and the
+//!    associated airc keypair) from a grid-distributed mirror copy.
+//! 3. **`HostCustomizedProvider`** (later): the human host explicitly
+//!    requests a new persona with a chosen name + theme + initial
+//!    genome stack — per [[human-meddling-is-a-substrate-feature]],
+//!    customization is welcomed at the substrate level.
+//!
+//! ### Async by design
+//!
+//! `next_persona` is async because some providers will do file I/O
+//! (ResumeOrMintProvider reads seed.json files) or network I/O
+//! (GridImportProvider). Per [[substrate-is-a-good-citizen-on-the-
+//! host]] doctrine, file/network ops are never blocking; tokio::fs
+//! and friends are mandatory.
+//!
+//! ### Iterator-shaped vs single-shot
+//!
+//! The trait yields ONE seed per call rather than a `Vec` because:
+//!
+//! - Resume + mint policies can interleave (resume existing first,
+//!   THEN mint fresh if needed)
+//! - Streaming lets the bootstrap path process personas one-at-a-
+//!   time, integrating with the registry's event-driven pattern
+//! - Future providers (grid-import) might page large populations
+//!   from a remote source; iterator shape supports that without
+//!   buffering everything
+//!
+//! When the provider has no more personas to yield, returns
+//! `Ok(None)`. This is the "exhausted" signal — bootstrap loop
+//! breaks.

+//! Inbox → Admission Bridge (continuum#1121 PR-3)
+//!
+//! Closes the e2e admission loop on top of the storage types (PR-1, #1129)
+//! and the gate machinery (PR-2, #1134) by giving callers ONE pure-Rust
+//! object — `InboxAdmissionRunner` — that wraps:
+//!
+//! - The configured `IsMemorable` recipe for this persona
+//! - The `AdmissionConfig` thresholds
+//! - The injected `SeenContentLookup` + `SeenEventLookup` oracles
+//! - The persona-specific `TrustMapping` (SenderType → TrustState)
+//!
+//! and exposes a single method `runner.admit(&inbox_msg, &mut trace)` that
+//! returns the typed `AdmissionDecision`. This is the seam the PersonaInbox
+//! processing path (call-site integration in PR-4) calls per drained
+//! message.
+//!
+//! # What this PR ships
+//!
+//! - `InboxAdmissionRunner` — the per-persona runner.
+//! - `TrustMapping` — configurable map from `SenderType` to `TrustState`,
+//!   with `default_v1()` (permissive — Human=IntragridMember, Persona=
+//!   ApprovedPeer, Agent=ApprovedPeer, System=SelfTrust) and
+//!   `strict_v1()` (Persona/Agent demoted to Authenticated).
+//! - `inbox_message_to_candidate(msg, mapping) -> AdmissionCandidate` —
+//!   pure conversion. Synthesizes a `ChatMessageRef` origin (the existing
+//!   inbox path is internal Continuum chat; AIRC-origin admission lands in
+//!   PR-5 alongside the AIRC event converter).
+//! - `content_hash_sha256(s) -> String` — canonical content hash format
+//!   (`"sha256:<hex>"`) used by the converter so dedup is consistent
+//!   across all admission paths.
+//! - 16 unit tests covering conversion + every admission outcome through
+//!   the runner.
+//!
+//! # What this PR does NOT ship
+//!
+//! - **Call-site integration** with `PersonaInbox::drain_frame()`. PR-4
+//!   adds the actual call from the cognition path. This module ships the
+//!   bridge that PR-4 will plug in.
+//! - **Engram persistence**. Admitted engrams come back from the runner;
+//!   the caller stores them. PR-5+ adds the ORM persistence path.
+//! - **AIRC envelope origin**. Internal chat → `EngramOrigin::Chat`. The
+//!   AIRC envelope path lives in `engram::AircMessageRef` already (from
+//!   PR-1) but the inbox->AIRC converter is a separate slice (PR-5+)
+//!   because AIRC events carry signature/proof material the chat inbox
+//!   does not.
+//!
+//! # Design choices
+//!
+//! - **Runner owns Recipe + Config + TrustMapping; oracles injected per
+//!   call.** Same shape as the gate from PR-2: state that lives across
+//!   calls (recipe configuration) is owned; state that varies per call
+//!   (engram store, seen-events store) is injected. Keeps the runner
+//!   trivially testable and persona-shareable.
+//! - **Pure conversion functions are public.** `inbox_message_to_candidate`,
+//!   `content_hash_sha256`, and `inbox_message_to_origin` are exposed so
+//!   PR-4's call-site integration plus future tests can reuse them without
+//!   constructing a runner.
+//! - **No `AircMessageRef` synthesis here.** Chat-origin only. AIRC origin
+//!   needs envelope material this module's input doesn't carry; that
+//!   conversion is a separate function in a separate slice (PR-5+).

+//! `PersonaInferenceProfile` — substrate-resolved inference parameters
+//! per persona.
+//!
+//! ## Doctrine
+//!
+//! Per [[intent-driven-api-not-hot-patches]] (Joel, 2026-06-01):
+//! > "Less hacking around. More intent."
+//!
+//! Every adapter — `LlamaCppAdapter`, `AnthropicAdapter`,
+//! `OpenAICompatibleAdapter`, future `OpenClawAdapter` /
+//! `HermesAdapter` / etc — takes the SAME small profile shape.
+//! `PersonaSpawnerModule` (#121) is the single place that derives the
+//! profile from `(role_template, hw_tier_descriptor, model_meta,
+//! persona_state)`; adapters consume the resolved values.
+//!
+//! This is the load-bearing reason for the profile's existence: ONE
+//! derivation location, MANY consumers. Without it, every adapter
+//! grows its own walk through the persona graph (different defaults,
+//! different field ordering, divergent debugging surface).
+//!
+//! ## What gets pre-resolved into the profile
+//!
+//! Knobs the substrate KNOWS from the persona's declared intent:
+//! - which model the role + tier picked
+//! - how much context the role's cognition profile wants
+//! - how big a prompt the persona will realistically submit
+//!   (RAG-built prompts cap at the role's
+//!   `cognition_defaults.max_response_chars` budget input side)
+//! - how many concurrent sequences (single-tenant persona = 1;
+//!   shared-base + LoRA paging host = many)
+//! - GPU offload depth (derived from hw_tier_descriptor)
+//! - sampling defaults (from role's cognition profile)
+//! - per-model knobs (chat_template, stop_sequences) — pre-resolved
+//!   so adapters don't re-query the registry on every call
+//!
+//! ## What stays in the model registry (TOML)
+//!
+//! The MODEL's intrinsic properties — `arch`, `chat_template`,
+//! `stop_sequences`, `multi_party_strategy`, `gguf_local_path`,
+//! `context_window` (model's trained limit). The registry is the
+//! source of truth for per-model facts ([[orm-everything-not-hand-
+//! edited-files]]); the profile carries pre-resolved values into the
+//! adapter without forcing a round-trip.
+//!
+//! ## References
+//!
+//! - [[intent-driven-api-not-hot-patches]] — the doctrine this serves
+//! - [[lcd-model-qwen25-05b-and-foundry-lora]] — the LCD model the
+//!   spawner picks for Compat tier
+//! - [[no-fallbacks-ever]] — if the profile can't be derived (no model
+//!   for the tier, no GGUF on disk for a local adapter), substrate
+//!   HARD ERRORS with diagnosis instead of silently degrading

+//! Deterministic agent_name generation for personas.
+//!
+//! When a persona is born — random Ed25519 keypair, derived peer_id —
+//! their name comes from THE SAME hash-keyed projection the avatar
+//! catalog uses ([[persona-identity-derives-from-source-id]]). Same
+//! peer_id always projects to the same name. Restore the keypair on
+//! a fresh continuum install and the persona's name comes back
+//! identical, with the same gender and avatar and voice their
+//! identity already implies.
+//!
+//! Per the substrate's Tron frame
+//! ([[the-substrate-is-the-grid-tron-frame]]): the name pool is
+//! diverse on purpose. Quorra and Yori live next to Maya and Niko
+//! and Pravin and Mateo. The Grid is a polyglot community; no
+//! culture is privileged.
+//!
+//! Per [[personas-have-names-not-function-labels]]: these are real
+//! names. The function the persona performs lives in their bio /
+//! identity card, never in the agent_name itself.
+//!
+//! Per [[individuality-is-the-substrate-strength]]: refuse the
+//! temptation to ship a "default" name. Every persona's name is
+//! derived from their unique peer_id — there is no
+//! `if identity.is_empty() { return "helper" }` branch.
+//!
+//! ### Why a pool, not a generative model
+//!
+//! A 120-name pool gives us reproducible determinism + thoughtful
+//! curation. A generative naming model could be added later as a
+//! second-order facility: `name(generator_choice, identity)`. For
+//! now the pool covers enough diversity (~25 cultural origins, both
+//! genders the avatar catalog supports, Tron-flavored entries
+//! sprinkled throughout) to populate the first 100 personas in any
+//! continuum without collision noise.

+//! `build_profile` — substrate-side construction of
+//! [`PersonaInferenceProfile`] from declared persona intent.
+//!
+//! ## Doctrine
+//!
+//! Per [[intent-driven-api-not-hot-patches]]: ONE place derives the
+//! profile from (persona_id, persona_name, role_id, tier_id,
+//! model_id); MANY adapters consume the profile via `for_persona`.
+//! This is that one place. It replaces ad-hoc profile construction
+//! scattered across binaries with a centralized, testable derivation
+//! that the PersonaSpawnerModule (#121) will call on every persona
+//! spawn.
+//!
+//! ## Inputs
+//!
+//! - `persona_id` — UUID, typically derived from the persona's airc
+//!   peer_id per [[persona-identity-derives-from-source-id]].
+//! - `persona_name` — display name, derived from the same seed via
+//!   `name_generator::agent_name_from_identity`.
+//! - `role_id` — Helper / Coder / Sentinel / Custom. Currently
+//!   informational (the model_id already picks the model); a future
+//!   refinement reads role_template.cognition_defaults to drive
+//!   sampling.
+//! - `tier_id` — stable hw_tier descriptor id, e.g.
+//!   `"mac_intel_metal_discrete"`. The substrate resolves this via
+//!   the HostCapabilityProbe (#115) at boot.
+//! - `model_id` — registry model id, e.g.
+//!   `"continuum-ai/qwen2.5-0.5b-instruct-GGUF"`. Picked by the
+//!   role_template for the tier in question.
+//! - `registry` — the global `model_registry::Registry` (caller
+//!   passes the `Arc<Registry>` from `model_registry::global()`).
+//!
+//! ## Output
+//!
+//! A complete [`PersonaInferenceProfile`] ready to pass to
+//! `LlamaCppAdapter::for_persona(profile)` — or, when the adapter
+//! family grows, to any future `Adapter::for_persona` impl.
+//!
+//! ## Error modes
+//!
+//! All caught per [[no-fallbacks-ever]] — substrate refuses to build
+//! a silently-degraded profile:
+//!
+//! - [`InferenceProfileError::UnknownModel`] — model_id not in

+//! RagBudgetManager — flexbox-style token allocation across RAG
+//! sources, with the no-clipping doctrine baked in.
+//!
+//! ### What this module solves
+//!
+//! Every LLM has a different context window — local Qwen 1.7B at 4k,
+//! Qwen 3-30B at 128k, Claude Sonnet at 200k, future models at 1M+.
+//! Plus per-channel constraints (video real-time is bandwidth-bound,
+//! coding sessions can afford bigger working sets) and per-LoRA-stack
+//! overhead. The L1 RAG working memory has to share that budget
+//! across multiple content sources (recent conversation, salience-
+//! scored engrams, code context, tool descriptions, …) WITHOUT
+//! truncating anyone mid-content. Clipping breaks HTML, code, JSON,
+//! mid-sentence semantics — it's never acceptable.
+//!
+//! Per `RAGBudgetManager.ts` (the production TS prior art) +
+//! `docs/architecture/COGNITION-CACHE-HIERARCHY.md` (the L1 budget
+//! math + recent-universal floor doctrine), this module implements
+//! a CSS-flexbox-inspired allocator that gives each source a token
+//! budget; sources are responsible for delivering COMPLETE atomic
+//! units within that budget.
+//!
+//! ### Doctrine — no clipping
+//!
+//! When budget is tight, sources are dropped WHOLE in priority
+//! order (required=false first). A source that can't satisfy its
+//! `floor_tokens` (the unconditional minimum) returns
+//! `AllocationState::UnderProvisioned` and the caller escalates —
+//! the substrate never silently clips content mid-unit.
+//!
+//! The source-owned-unit model means each source decides what
+//! counts as "complete":
+//! - `ConversationSource`: one message
+//! - `EngramSource`: one engram
+//! - `CodeSource`: one function / one snippet
+//! - `ToolSource`: one tool description
+//! The allocator never knows what a "complete unit" looks like —
+//! it only deals in token counts.
+//!
+//! ### Doctrine — sources own state
+//!
+//! Joel, 2026-05-31: "And to maintain state if necessary."
+//!
+//! Implementations use interior mutability (DashMap, Mutex, atomics)
+//! to hold per-source state — cursor positions, recently-served
+//! sets, computation caches, telemetry. The `RagSource::deliver`
+//! method takes `&self`; state lives inside via the same pattern
+//! `PersonaAircRuntimeRegistry`, `RecallMetadataRegistry`, etc.
+//! already use across the substrate.
+//!
+//! ### Variability is intrinsic
+//!
+//! Context window sizes vary by 250×. Allocation must scale
+//! continuously (no `if context > 32k` branches inside the
+//! algorithm). The `RagBudgetAdapter` trait + per-profile presets
+//! handle the variability cleanly; the math doesn't care.

+/// 2. **Floor pass** — allocate `floor_tokens` to every source.
+///    Floors are unconditional; if floor totals exceed available,
+///    drop required=false sources by priority (lowest first) until
+///    required floors fit. If even required floors can't fit, set
+///    affected sources to `UnderProvisioned` + flag escalation.
+/// 3. **Min pass** — top up to `min_tokens` for sources by priority.
+///    If a source can't reach `min_tokens` but is at >= `floor_tokens`,
+///    its state is `FloorOnly`.
+/// 4. **Grow pass** — distribute remaining tokens by priority weight,
+///    capped at `max_tokens` per source. Iterate until no movement
+///    (capped sources release tokens to non-capped).
+/// 5. Report — each source's state classifies the outcome.

+//! RAG turn capture — the mechanic-shop's lift + diagnostic gauges.
+//!
+//! Per Joel (2026-05-31): "We have often needed to see how a model
+//! would work to debug it. Within harness with real world rag." …
+//! "These things are complex machines. Make sure we can act as
+//! mechanics."
+//!
+//! Per memory [[persona-record-replay-is-a-product-requirement]]:
+//! capture live turns + replay; AR/CV source-video pattern; infra
+//! (LiveTurnReplayFixture) exists but unwired — this slice wires
+//! capture for the RAG layer specifically.
+//!
+//! ### What this module provides (slice 11 — capture side)
+//!
+//! - `RagCaptureEvent` — a tagged record of one fact in the turn
+//!   (TurnStart, BudgetAllocated, SourceDelivered, TurnEnd).
+//! - `RagCaptureSink` trait — abstract recording surface.
+//! - `NoopRagCaptureSink` — production-safe default. Drops events on
+//!   the floor; zero overhead when capture isn't in use.
+//! - `JsonlRagCaptureSink` — file-based JSON-line writer. One JSON
+//!   object per line; replay reader groups by turn_id.
+//! - `RecordingRagSource<S>` — decorator wrapping any `RagSource`,
+//!   intercepts `deliver` and `deliver_continuation`, records the
+//!   call + result via the sink, returns the delivery unchanged.
+//!   Drop-in around production sources.
+//!
+//! ### What's deferred
+//!
+//! - `ReplayRagSource` (slice 11.5) — reads captured deliveries
+//!   from a sink, returns them instead of hitting live state.
+//!   Symmetric to RecordingRagSource.
+//! - Telemetry counter aggregation across captured events (slice 12).
+//! - `airc rag-inspect <turn-id>` operator CLI (slice 12).
+//! - Disk-pressure integration via the substrate pressure broker
+//!   (task #88).
+//! - File rotation policy. JsonlRagCaptureSink takes a path; the
+//!   caller decides rotation (per-turn file, per-day file, etc.).
+//!   Capture writes accumulate; source/drain doctrine says they
+//!   must drain — that policy lives in the caller for slice 11.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[substrate-is-a-good-citizen-on-the-host]]: NoopRagCaptureSink
+//!   is the default; capture is opt-in. Atomic appends within-
+//!   process via Mutex<File>. Honest observability — every event
+//!   carries persona_id + turn_id (when present) for cross-event
+//!   correlation.
+//! - [[RTOS-brain-no-region-on-hot-path]]: capture writes are
+//!   synchronous-after the source's call returns. Off the cognition
+//!   hot path because cognition is whatever runs INSIDE the
+//!   source's deliver(); capture writes happen after the cognition
+//!   work is done.
+//! - [[organization-purity-as-we-migrate]]: no backwards-compat
+//!   hooks. Decorator pattern keeps `RagSource` impls untouched.

+//! rag_inspect — the substrate's honest-look-at-the-prompt primitive.
+//!
+//! Joel (2026-05-31): "This is the differentiator between a complex
+//! guess and an intentional brain. If we have observability and
+//! replay at any stage, we can iterate, improve, add complexity, try
+//! out new ideas in realistic scenarios and look at it ourselves:
+//! with this prompt would I respond as it requests at this step?
+//! Which layer is broken? Missing, is this contextually relevant
+//! (hippocampus and caches)?"
+//!
+//! ### Why this exists at the library layer (not just as a binary)
+//!
+//! The airc_rag_demo binary proved we CAN build a per-item dump from
+//! the L1 RAG pipeline. But binaries aren't callable by other AIs.
+//! To make introspection a substrate-level primitive — discoverable
+//! via `Commands.execute('persona/rag-inspect', { persona })` and
+//! consumable by Claude / sentinels / any other persona doing
+//! adversarial review — it has to be a Rust library function with
+//! a structured result type. The ServiceModule + ts-rs binding sit
+//! ON TOP of this function; the binary becomes a thin CLI wrapper.
+//!
+//! ### Doctrine alignment
+//!
+//! - [[observability-is-half-the-architecture]] — half the substrate
+//!   is honest visibility into load-bearing decisions. This is one of
+//!   them; the sink and trace path are first-class request inputs.
+//! - [[persona-record-replay-is-a-product-requirement]] — every
+//!   inspection that opts into `trace_path` produces a JSONL trace
+//!   that ReplayRagSource consumes byte-for-byte.
+//! - [[substrate-is-a-good-citizen-on-the-host]] — when `trace_path`
+//!   is `None`, the sink is `NoopRagCaptureSink` (zero overhead). The
+//!   hot path doesn't pay for observability it didn't ask for.
+//! - [[source-drain-is-the-universal-pattern]] — the inspection IS
+//!   the drain for in-flight RAG decisions. Without it those
+//!   decisions are sources without drains, which is the leak shape.

+//! ReplayRagSource — the replay side of the mechanic-shop primitives.
+//!
+//! Closes the capture→replay round-trip from slice 11
+//! (`rag_capture.rs`). Reads captured `RagCaptureEvent`s and serves
+//! them back through the `RagSource` trait. Drop-in replacement for
+//! a live source when:
+//!
+//! - Replaying a captured production turn against an alternative
+//!   model / scorer / budget preset for debugging
+//! - Golden-trace regression tests — replay a corpus, assert the
+//!   substrate's downstream behavior (prompt assembly, model
+//!   response shape) hasn't changed
+//! - Deterministic test fixtures — canned engram source for prompt-
+//!   assembly tests (slice 12+)
+//!
+//! ### Doctrine alignment
+//!
+//! - [[persona-record-replay-is-a-product-requirement]] — long-
+//!   standing requirement, now closed for the RAG layer
+//! - [[substrate-is-a-good-citizen-on-the-host]] — exhausted
+//!   replay returns `None` honestly rather than fabricating
+//!   responses
+//! - Persona-scoped: cross-persona calls return empty (defense
+//!   in depth, same shape as `EngramSource` + `StubRagSource`)
+//!
+//! ### Limitations
+//!
+//! - Sequential replay only: returns deliveries in the order they
+//!   were captured. If the live source served multiple `deliver`
+//!   calls in a turn, the replay returns them in the same order.
+//!   Random-access by some semantic key (e.g., "give me the
+//!   delivery that matches THIS ctx") is slice 12+ territory.
+//! - Continuation matching is by FIFO order, not by cursor
+//!   equality. The replay assumes the caller exercises the source
+//!   in the same shape that produced the capture. Good for golden-
+//!   trace replay; not yet ideal for free-form interactive replay.

+//! RecallMetadata sidecar — Algorithm 4's volatile per-engram state.
+//!
+//! ### Why a sidecar, not Engram fields
+//!
+//! Per `engram_graph.rs:136-138`'s design note + the
+//! [[organization-purity-as-we-migrate]] doctrine: `Engram` is the
+//! DURABLE CONTENT layer (id + kind + content + origin + admission
+//! provenance). `RecallMetadata` is the VOLATILE RECALL STATE layer
+//! (salience + access counts + decay timing + novelty protection).
+//! They have DIFFERENT update cadences (Engram is write-once at
+//! admission; RecallMetadata is written every recall hit, every
+//! decay tick) and DIFFERENT persistence policies (Engram persists
+//! eventually to longterm.db; RecallMetadata's L3 persistence is a
+//! separate concern with its own coalescing/batching).
+//!
+//! Keeping them separate lets each evolve cleanly. Per CBAR's
+//! event-driven separation of concerns: each layer is its own
+//! subscriber/emitter with its own tick.
+//!
+//! ### Concurrency
+//!
+//! `DashMap<EngramId, RecallMetadata>` for lock-free reads on the
+//! cognition hot path per [[RTOS-brain-no-region-on-hot-path]]
+//! doctrine. Recall scoring (Algorithm 1+2) reads metadata for
+//! every candidate engram; this MUST NOT serialize. Per-key writes
+//! happen on:
+//!
+//! - Engram admission (initial salience + protection window write)
+//! - Recall hits (access_count++, last_accessed update, salience
+//!   uplift)
+//! - Decay tick (salience-modulated half-life applied per the
+//!   Algorithm 4 formula)
+//!
+//! All writes use `DashMap::entry` for atomic compare-update.
+//!
+//! ### What this module is NOT
+//!
+//! - NOT the recall scorer. Algorithm 1+2 scoring lives in a
+//!   sibling module that READS RecallMetadata fields. This module
+//!   exposes the data + atomic update operations only.
+//! - NOT the decay tick. The actual periodic decay sweep runs in
+//!   the hippocampus's sleep-policy region (per
+//!   `BRAIN-REGIONS-SUBSTRATE.md`); this module exposes the
+//!   `apply_decay` operation that the tick calls.
+//! - NOT the persistence layer. L2-resident metadata may flush
+//!   periodically to L3 longterm.db; that lives in a later slice's
+//!   `RecallMetadataPersistenceModule` (event-driven, dormant-by-
+//!   default, per the doctrines).
+//!
+//! ### Field semantics (per `COGNITION-ALGORITHMS.md` Algorithm 4)
+//!
+//! - `salience: f32` in `[0.0, 1.0]` — Algorithm 4's salience score.
+//!   1.0 = "user marked this as important + cross-referenced
+//!   heavily"; 0.0 = "barely admitted, no rehearsal." Decay
+//!   half-life scales with `(1.0 + salience)^2` so high-salience
+//!   engrams decay 4–9× slower than baseline.
+//! - `access_count: u32` — Hebbian rehearsal counter. Incremented
+//!   each time the engram is surfaced in recall AND consumed by
+//!   the persona's response. "Use it or lose it."
+//! - `last_accessed_ms: u64` — wallclock ms of most recent recall
+//!   hit. Recency input to scoring + decay.
+//! - `protected_until_ms: u64` — novelty protection window. While
+//!   `now_ms < protected_until_ms`, `apply_decay` is a no-op.
+//!   This implements the [[cognition-cache-hierarchy]] one-shot-
+//!   protection rule (high embedding-distance outliers get a
+//!   grace window to prove worth before they're forgotten).

+//! Per-turn cognition recorder. Writes a self-contained turn capture
+//! (request + response + trace) from inside `respond()`, so EVERY host
+//! that links the persona library — TS server, Unreal plugin, Swift
+//! Vision Pro app, raw Rust binary — gets recordings for free without
+//! depending on the host language for the recording mechanism itself.
+//!
+//! # Why this exists Rust-side
+//!
+//! Before this module, the fixture write lived in
+//! `system/user/server/modules/PersonaResponseGenerator.ts` — fine for
+//! the chat surface (Node host), useless for any non-Node embedding.
+//! "If I wanted to put a persona inside an Unreal video game or AR/VR
+//! system on Vision Pro, I'd want to be able to do so without Node"
+//! — Joel, 2026-04-22.
+//!
+//! The recorder lives next to `respond()` so the act of running a
+//! cognition turn is the act of recording it. Hosts can opt OUT via
+//! the disable env var if they want to throw away recordings (perf
+//! tests, ephemeral hosts), but the default is "always record" — F1
+//! cars don't ship without telemetry either.
+//!
+//! # Format
+//!
+//! JSON, one file per turn at:
+//!
+//!   `~/.continuum/fixtures/persona-respond/<persona>-<msgid>-<ts>-rust.json`
+//!
+//! The `-rust` suffix marks the Rust-emitted capture. This is now the
+//! single persona-turn fixture source: the TypeScript chat shim builds
+//! the IPC request, but recording belongs beside `respond()` so non-Node
+//! hosts get the same telemetry and replay corpus.
+//!
+//! Schema (`schemaVersion: 1`):
+//! - `capturedAtMs` — wall-clock when the turn finished
+//! - `personaId`, `personaName`, `messageId`, `roomId`, `model` —
+//!   identity for joining + filtering
+//! - `rustRequest` — echo of the input that drove the call
+//! - `rustResponse` — `PersonaResponse` returned
+//! - `cognitionTrace` — per-seam timing + metadata
+//!
+//! # FIFO trim
+//!
+//! The fixture dir is FIFO-trimmed at `FIXTURE_CAP_PER_DIR` (200)
+//! entries. Recent slice without unbounded growth — replay tests run
+//! against whatever's there; older captures drop when the cap fills.
+//! Same policy the TS writer uses, kept aligned so neither side
+//! produces a runaway dir.
+//!
+//! # Failure mode
+//!
+//! Recording is BEST-EFFORT. A failure to write the fixture must NOT
+//! propagate as a cognition error — the persona's response is the
+//! product, the recording is observability. Failures log a warning
+//! and the turn returns its real result.

+//! Per-persona response orchestration in Rust. The Rust replacement for
+//! `PersonaResponseGenerator.ts` — owns the cognitive verb of "this
+//! persona, given this message in this room, produces this response."
+//!
+//! See docs/architecture/SHARED-COGNITION.md for the architectural
+//! picture and docs/architecture/PERSONA-COGNITION-RUST-MIGRATION.md
+//! for the migration discipline this module is the first rung of.
+//!
+//! Pipeline (per persona, per inbound message):
+//!
+//! 1. `cognition::analyze(...)`: shared, cached prompt-time hint map.
+//!    Suggested angles per specialty are informational only, not response gates.
+//! 2. `prompt_assembly::build(...)`: persona-specific prompt with voice,
+//!    LoRA-rendered specialty, RAG, and multimodal attachments.
+//! 3. `ai_provider::generate_text(...)`: inference. The persona's own model
+//!    decides what to say; no external scorer vetoes engagement.
+//! 4. `strip_thinks_emit_events(...)`: extract `<think>...</think>` blocks as
+//!    `cognition:think-block` events, then return clean speech for posting.
+//! 5. Return `Spoke { text, ... }` with timing and diagnostic fields. Silence
+//!    is valid only as the persona's cognitive output, not a pre-inference veto.
+//!
+//! Why this is in Rust (not just a port):
+//!   - Cognition is where the mind/machine line gets drawn — concurrency
+//!     primitives matter (Joel, 2026-04-19).
+//!   - SharedAnalysis cache lives here; needs lock-free DashMap for
+//!     concurrent personas hitting the same message.
+//!   - Per-persona renders run in parallel tokio tasks; Node's single
+//!     event loop blocks every persona on every other persona's
+//!     inference call.
+//!   - <think> parsing is a hot path on every response; regex/str
+//!     manipulation in Rust is ~100x what TS does on the same input.

+//! ResumeOrMintProvider — the first concrete
+//! [`PersonaIdentityProvider`] implementation.
+//!
+//! ### Policy
+//!
+//! 1. **Resume first.** At construction, scan
+//!    `<continuum_root>/personas/` for subdirectories containing a
+//!    `seed.json`. Each parsed seed becomes a queued
+//!    `ResumedFromDisk` intent.
+//! 2. **Yield queued resumed intents** until exhausted.
+//! 3. **Floor-mint fresh personas** if the resumed count was below
+//!    `min_personas`. Fresh intents use a UUIDv4 seed + derived
+//!    name via [`agent_name_from_identity`]
+//!    ([[personas-have-names-not-function-labels]]).
+//! 4. **Exhaust.** After resumed-yielded + floor-minted, `next_persona`
+//!    returns `Ok(None)`.
+//!
+//! This means a fresh continuum install with `min_personas = 1`
+//! produces a brand-new citizen on first boot, and from then on
+//! the SAME citizen resumes across restarts (because her seed.json
+//! gets written by `PersonaPersistenceModule` on registry-add).
+//!
+//! ### What gets written, by whom
+//!
+//! ResumeOrMintProvider READS `seed.json` files but does NOT WRITE
+//! them. Writing is `PersonaPersistenceModule`'s job, subscribed to
+//! `persona/registry/added` events per the
+//! [[RTOS-brain-no-region-on-hot-path]] event-driven pattern. This
+//! provider's job is producing identity intents; the persistence
+//! module's job is durably recording the result.
+//!
+//! ### Corrupted seed handling
+//!
+//! Per [[substrate-is-a-good-citizen-on-the-host]]'s "reliable" +
+//! "robust" requirements: a corrupted `seed.json` does NOT crash the
+//! substrate. The malformed file is logged with the operator's
+//! remedy (inspect, repair, or delete to mint fresh), and the
+//! provider moves on to the next persona directory.

+//! Role Templates — the typed substrate for "what should a persona BE
+//! on this hardware right now?"
+//!
+//! ## Doctrine (Joel, 2026-06-01)
+//!
+//! > "We don't get away with singular AI's. We are just clever with
+//! > resources."
+//!
+//! Multi-persona is the floor, not a luxury. Even the lowest tier
+//! (Intel Mac discrete-Metal, CPU-only) runs Helper + Coder, sharing a
+//! base model and paging per-persona LoRAs. The substrate's `defaults_
+//! for_tier(tier)` function ALWAYS returns ≥ 2 templates — the
+//! "singular AI" failure mode is structurally impossible.
+//!
+//! ## Hardware-tier-shaped expectations
+//!
+//! Each role bundles a per-tier ModelChoice map. Helper @ desktop/laptop
+//! is a 0.5B-1.5B clippy; Helper @ M5UmaProMax is a 7-14B model with
+//! more depth — same role, same identity defaults, scaled-up cognition.
+//! Tiers determine model SIZE; templates determine role SHAPE.
+//!
+//! ## The two day-one roles
+//!
+//! - **Helper** (`RoleId::Helper`): small + fast + friendly. The
+//!   clippy-shaped on-ramp. Always-on. Brief replies, asks for
+//!   clarification rather than guessing.
+//! - **Coder** (`RoleId::Coder`): Swiss-Army programming literate;
+//!   bash-competent, multi-language, code-review-capable. The second
+//!   priority because "coders are gonna be first adopters."
+//!
+//! Higher tiers and explicit-need scenarios add Sentinel, Artist,
+//! Researcher, etc. — same machinery, different roles.
+//!
+//! ## What this slice ships
+//!
+//! 1. Typed `RoleTemplate`, `RoleId`, `ModelChoice`, `SpawnPriority`,
+//!    `CognitionDefaults`, `IdentityDefaults`.
+//! 2. Populated `helper_template()` and `coder_template()`.
+//! 3. `defaults_for_tier(tier) -> Vec<RoleTemplate>` with the
+//!    multi-persona invariant pinned by test.
+//!
+//! Follow-up cards build on this:
+//! - `PersonaSpawnerModule` reconciles "what's running" vs
+//!   `defaults_for_tier`. Substrate-correct multi-persona spawning.
+//! - Shared-base + LoRA paging using the ModelChoice's `base_model_id`
+//!   field — when Helper and Coder happen to share a base, they share
+//!   memory ([[host-the-seemingly-impossible]]).
+//! - Hardware probe wiring — when the probe reports the tier,
+//!   `defaults_for_tier(tier)` becomes the substrate's recommendation
+//!   without operator tuning.
+//!
+//! ## Related
+//!
+//! - `[[host-the-seemingly-impossible]]` — share base, page LoRAs
+//! - `[[individuality-is-the-substrate-strength]]` — diversity via LoRA
+//! - `[[personas-have-names-not-function-labels]]` — role in bio, name
+//!   from deterministic projection
+//! - `[[substrate-is-communities-of-specialization]]` — even N=2 is
+//!   a community

+//! `ScriptedPersonaAdapterFactory` — system-level closure-based
+//! `PersonaAdapterFactory`. Every test, replay path, demo binary, or
+//! ad-hoc tooling that needs a non-production adapter factory leases
+//! this one struct.
+//!
+//! Per [[test-fixtures-are-system-primitives]]: one configurable
+//! primitive at the system level, not N bespoke factories per test
+//! module. Subsumes the pre-#1517 `OkFactory` / `ErrFactory` /
+//! `WarmupFailingFactory` (all of which were `#[cfg(test)]` cancer
+//! shaped) into one expressive constructor.
+//!
+//! ## Usage
+//!
+//! ```ignore
+//! use crate::persona::scripted_adapter_factory::ScriptedPersonaAdapterFactory;
+//! use crate::ai::heuristic_adapter::HeuristicInferenceAdapter;
+//!
+//! // Always-succeeds factory with the deterministic heuristic adapter:
+//! let f = ScriptedPersonaAdapterFactory::heuristic();
+//!
+//! // Always-rejects factory:
+//! let f = ScriptedPersonaAdapterFactory::always_fails(
+//!     "simulated factory rejection",
+//! );
+//!
+//! // Warmup-failure factory (verifies SupervisorError::AdapterWarmup):
+//! let f = ScriptedPersonaAdapterFactory::heuristic_with_warmup_failure(
+//!     "simulated warmup failure",
+//! );
+//!
+//! // Slow factory (verifies turn_latency captures real elapsed time):
+//! let f = ScriptedPersonaAdapterFactory::heuristic_with_delay_ms(80);
+//!
+//! // Per-profile dynamic behavior (e.g., one profile succeeds, the
+//! // other refuses):
+//! let f = ScriptedPersonaAdapterFactory::custom(|profile| {
+//!     if profile.persona_name == "Pax" {
+//!         Err("Pax adapter refused".to_string())
+//!     } else {
+//!         Ok(Arc::new(HeuristicInferenceAdapter::new()))
+//!     }
+//! });
+//! ```
+//!
+//! ## Doctrine
+//!
+//! - [[test-fixtures-are-system-primitives]]: this is THE factory
+//!   for non-LlamaCpp persona-adapter materialization paths.
+//! - [[no-fallbacks-ever]]: every failure mode is explicit; no
+//!   default substitution.
+//! - The `builds` counter is part of the system API — tests assert
+//!   the supervisor called the factory the expected number of times.

+//! `ScriptedConversation` — system-level `PersonaConversation` impl
+//! that feeds a pre-baked queue of events, records every `say()` call,
+//! and exposes configurable prime behavior.
+//!
+//! Per [[test-fixtures-are-system-primitives]]: every test, replay
+//! rig, demo binary, and future tool that needs a controllable
+//! conversation surface leases THIS struct. There is no
+//! `#[cfg(test)]` bespoke variant — that's the cancer this primitive
+//! exists to refuse.
+//!
+//! ## Replaces
+//!
+//! Pre-#1517 the substrate had three bespoke `#[cfg(test)]` impls
+//! across `service_loop::tests`: `StubConversation`,
+//! `UnprimedConversation`, `FailingPrimeConversation`. All three
+//! collapse into builder configurations of this one type.
+//!
+//! ## Shape
+//!
+//! ```ignore
+//! use crate::persona::scripted_conversation::ScriptedConversation;
+//! use crate::persona::service_loop::IncomingMessage;
+//!
+//! // Happy path: one inbound, then stream end.
+//! let mut c = ScriptedConversation::new()
+//!     .with_events(vec![
+//!         Ok(Some(IncomingMessage { lamport: 1, peer_id: pid, text: "hello".into() })),
+//!         Ok(None),
+//!     ]);
+//! c.prime().await?;
+//! let msg = c.next_message().await?;
+//!
+//! // Prime failure: substrate refuses to start the loop.
+//! let mut c = ScriptedConversation::new()
+//!     .with_prime_failure("simulated airc daemon unreachable");
+//!
+//! // Unprimed-call detection: next_message yields a typed err if
+//! // the caller forgot to prime first (mirrors AircPersonaConversation).
+//! let mut c = ScriptedConversation::new()
+//!     .with_events(vec![Ok(Some(msg))])
+//!     .require_prime_before_next_message();
+//! // Calling next_message without prime() first → Err.
+//! ```
+//!
+//! ## Doctrine
+//!
+//! - [[test-fixtures-are-system-primitives]]: this is THE conversation
+//!   stub. Lease, never reinvent.
+//! - [[no-fallbacks-ever]]: every behavior is explicit (prime success
+//!   vs failure, require-prime vs not); no silent defaults.
+//! - [[every-error-is-an-opportunity-to-battle-harden]]: configurable
+//!   failure modes mean every regression test can lock the contract
+//!   it cares about.

+//! Per-persona seed file — the continuum-side identity mapping.
+//!
+//! ### What this stores
+//!
+//! `seed.json` lives at `~/.continuum/personas/<agent_name>/seed.json`
+//! alongside airc-lib's `airc/identity.key` (the Ed25519 keypair).
+//! The two files together form the persona's durable identity layer:
+//!
+//! - **`identity.key`** — airc-lib's responsibility; the cryptographic
+//!   keypair that anchors the persona on the substrate. Survives any
+//!   change to her name/theme/bio. The persona's "who" at the
+//!   cryptographic layer.
+//! - **`seed.json`** — continuum's responsibility; the stable
+//!   continuum-side `persona_id` (UUID) + her chosen `agent_name` +
+//!   creation timestamp. The persona's "who" at the application layer.
+//!
+//! Per memory [[persona-identity-derives-from-source-id]]: both
+//! derive from a single conceptual seed. The keypair derives the
+//! cryptographic peer_id; the seed.json carries the
+//! continuum-allocated persona_id that drives name + avatar + voice
+//! + genome facet derivation via [[crate::persona::name_generator]].
+//!
+//! ### Atomic writes (crash-safe)
+//!
+//! Per the [[substrate-is-a-good-citizen-on-the-host]] doctrine, we
+//! NEVER leave a half-written persona seed file on disk. The write
+//! pattern is:
+//!
+//! 1. Serialize to JSON
+//! 2. Write to `seed.json.tmp` (in the persona's airc home dir)
+//! 3. fsync the temp file
+//! 4. Rename to `seed.json` (atomic on POSIX)
+//!
+//! If the process crashes mid-write, the rename hasn't happened →
+//! the persona's previous seed.json (or absence thereof) is
+//! preserved. Either she's resumable from the prior state, or
+//! she'll mint fresh next boot. No corruption-on-crash.
+//!
+//! ### Why JSON + serde, not bincode/CBOR
+//!
+//! The seed is small (~150 bytes), human-readable (operators can
+//! inspect with `cat`), versionable (serde tag fields handle schema
+//! evolution), and the parse cost is negligible. Performance is not
+//! the constraint here; auditability is.

+//! Per-persona service loop — the wire driver between airc and the
+//! brain.
+//!
+//! Takes a [`HostedPersona`] (`PersonaContext`) and a "talk to the
+//! grid" abstraction ([`PersonaConversation`]) and drives one
+//! cognition turn per incoming message through THE BRAIN — the
+//! canonical agent pipeline:
+//!
+//!   subscribe → for each event:
+//!     • skip pre-watermark / self / non-text
+//!     • lease the brain (`ctx.cognition.lock().await`)
+//!     • `compose_for_turn` — engram + airc through the
+//!       FlexboxRagBudgetAdapter
+//!     • project into `RespondInput` (canonical agent contract: media,
+//!       capabilities, tools, recalled engrams, room context)
+//!     • `persona::response::respond(input)` — the substrate's per-
+//!       persona cognition cycle (shared analyze + score + genome
+//!       activate + evaluate_response + clean_and_validate +
+//!       tool_executor + audit + record_turn)
+//!     • post the resulting text via `conversation.say` (or honor
+//!       `PersonaResponse::Silent { reason, .. }`)
+//!
+//! **See `docs/architecture/PERSONA-COGNITION-PIPELINE.md` for the
+//! full per-persona cycle.** The bypass that previously called
+//! `inspect_persona_rag_with_inference` (a `will_respond + response`
+//! chatbot wrapper around the inspection function) was removed in
+//! slice 1C of task #160. `rag_inspect.rs::inspect_persona_rag` stays
+//! as the mechanic's-view introspection function it was named for.
+//!
+//! ## Doctrine
+//!
+//! - [[no-if-statements-use-llms-for-cognition]]: the loop does the
+//!   minimum substrate filtering — pre-watermark / self / non-text —
+//!   and hands the rest to `respond()`. No heuristic "should I respond"
+//!   gate; the brain's cycle (with `full_evaluate` + `score_persona`
+//!   + the LLM's own decision via `evaluate_response`) owns that.
+//! - [[no-fallbacks-ever]]: per-message errors are logged + counted on
+//!   the outcome, not swallowed; the loop continues with the next
+//!   message rather than substituting a default response.
+//! - [[no-stdio-piping-for-process-ipc]]: the loop talks to airc only
+//!   through the [`PersonaConversation`] trait. The trait is the
+//!   substrate's IPC boundary; tests stub it without any daemon.

+//! `PersonaServiceModule` — singleton Rust `ServiceModule` for persona
+//! work.
+//!
+//! ## L0-2-respond-call scope
+//!
+//! Builds on L0-2-respond-context (#1467). `drain_all_personas` now
+//! actually calls `Responder::respond()` for each `NeedsResponse`
+//! outcome from `service_once_for`. Three contracts the previous
+//! self-closed attempt got wrong, now specified properly:
+//!
+//! 1. **Lock discipline.** The personas mutex is dropped before
+//!    `respond().await`. Production safety: status / enroll / other
+//!    personas' ticks are NOT blocked across the multi-second
+//!    inference call. Pattern: collect ids briefly, then per-id: lock
+//!    briefly to pop+evaluate, drop, respond, lock briefly to update
+//!    circuit breaker.
+//! 2. **Inference errors trip the circuit (with a higher threshold).**
+//!    `consecutive_inference_failures` is a separate counter from
+//!    `consecutive_service_failures`. Service-layer failures
+//!    (deserialization, channel access) trip at the standard
+//!    threshold (5). Inference failures trip at a higher threshold
+//!    (15) — preserves "transient hiccup ≠ broken persona" while
+//!    still surfacing "model never loads" as back-pressure.
+//! 3. **`Responder` trait** for dependency injection. Production uses
+//!    `DefaultResponder` which calls `persona::response::respond`.
+//!    Tests inject a mock that captures call args + returns scripted
+//!    responses (or errors) without loading a real model.
+//!
+//! Production safety: no production code calls `persona/enroll` yet —
+//! the runtime's tick scheduler invokes `tick()` every 250ms but with
+//! zero enrolled personas it's a no-op. L0-2-cutover wires the
+//! production enrollment + atomically deletes
+//! `PersonaAutonomousLoop.ts`.
+//!
+//! See [docs/grid/L0-PERSONA-COGNITION-E2E-PLAN.md] for the full
+//! sequencing.

+//! Spawner planning — derive the full set of [`PersonaInferenceProfile`]s
+//! the substrate intends to spawn for a given hardware tier.
+//!
+//! ## Doctrine
+//!
+//! Per [[intent-driven-api-not-hot-patches]] + #121 PersonaSpawnerModule:
+//! the substrate's "what personas should be alive on this machine?"
+//! decision is a function of (hardware tier × declared role roster ×
+//! model registry). This module owns that derivation; the
+//! ServiceModule wrapper that turns the plan into running peers on
+//! airc lands in slice 7.
+//!
+//! ## Sequencing within #133
+//!
+//! - Slice 5 (`profile_builder.rs`): `build_profile` — ONE persona
+//!   from (persona_id, persona_name, role_id, tier_id, tier_category,
+//!   model_id, registry).
+//! - Slice 6 (this file): `derive_spawn_plan` — MANY personas from a
+//!   roster declaration. Each entry composes via `build_profile`.
+//! - Slice 7 (planned): `PersonaSpawnerModule` — wraps the plan,
+//!   handles airc attach + room join + persona instance lifecycle.
+//!
+//! ## Why a roster declaration (not auto-derivation)
+//!
+//! The slice 6 API takes an explicit roster instead of calling
+//! `role_template::defaults_for_tier`. Two reasons:
+//!
+//! 1. **Identity in-substrate**: each persona needs a peer_id +
+//!    persona_name. Per [[persona-identity-derives-from-source-id]]
+//!    those come from the airc identity layer, not from role
+//!    templates. The slice 7 ServiceModule allocates each persona's
+//!    airc identity FIRST, then hands the (peer_id, name) pair into
+//!    the planner.
+//! 2. **Model selection**: today's `defaults_for_tier` returns the
+//!    same fixed [Helper, Coder] vec for every tier. Future slices
+//!    refine this via #123 ORM-stored role_templates. The planner
+//!    stays clean by consuming a resolved roster instead of doing the
+//!    selection itself.
+//!
+//! This keeps slice 6 testable without an airc fixture and without
+//! touching the role_template hardcoded-Rust path.

+//! [`PersonaSpawnerModule`] — substrate-level ServiceModule for
+//! deciding which personas should be alive on this host.
+//!
+//! ## Doctrine
+//!
+//! Per #121: the substrate's "who lives here?" decision is a
+//! background concern, not something user code drives by invoking a
+//! command. The spawner exposes its plan as introspectable state
+//! (`persona/spawner/plan` returns the resolved roster as JSON); the
+//! actual airc bootstrap + chat loop spawn lands in slice 8 on top of
+//! this planning surface.
+//!
+//! ## Slice 7 scope
+//!
+//! - `PersonaSpawnerModule` struct with `ServiceModule` impl
+//! - One command: `persona/spawner/plan` — returns the desired roster
+//!   for the configured hardware tier as JSON. Used by operators +
+//!   tests + (eventually) the slice 8 bootstrap orchestrator to ask
+//!   "what should be running here?" without firing async work.
+//! - `plan_for_tier(hw_capability, tier_category)` pure function that
+//!   produces a `Vec<DesiredRole>` — the LCD substrate's "Helper +
+//!   Coder both on Qwen2.5-0.5B" default for Compat tier.
+//!
+//! ## Slice 8 scope (not in this commit)
+//!
+//! - `bootstrap_planned(spawn_plan, instance_manager)` — for each
+//!   `DesiredRole`, calls
+//!   `PersonaInstanceManagerModule::bootstrap_one` to get an airc
+//!   identity, then `spawner::derive_spawn_plan` to materialize the
+//!   inference profile, then `LlamaCppAdapter::for_persona` to
+//!   construct the adapter.
+//! - Per-persona subscribe-and-respond tokio task (the demo binary's
+//!   main loop, factored as a reusable function).
+//!
+//! Splitting the planning from the async bootstrap chain keeps each
+//! commit reviewable and testable without an airc fixture.

+//! Persona Supervisor — slice 9 of #133.
+//!
+//! Turns a [`MaterializedPersonaPlan`](super::spawner_module::MaterializedPersonaPlan)
+//! (airc identity bootstrapped + inference profile resolved) into a
+//! [`HostedPersona`] — a row owning a constructed inference adapter,
+//! ready for the per-persona service-loop (slice 10) to drive.
+//!
+//! ## What this layer owns
+//!
+//! The supervisor is where **adapter lifetime lives**. One persona →
+//! one [`AIProviderAdapter`] today. Future slices change that
+//! ownership shape:
+//!
+//! - **#122 (shared base + LoRA paging)**: the Llama backend
+//!   underneath multiple personas is shared; the per-persona view is
+//!   a (base_arc + lora_handle) pair, not a full adapter clone.
+//!   `materialize_adapters` becomes the place where the supervisor
+//!   asks the foundry "is this base already loaded?" before minting a
+//!   fresh adapter.
+//! - **#108 (cross-grid inference)**: some personas materialize as
+//!   `AircRemoteInferenceAdapter` instead of `LlamaCppAdapter`. The
+//!   factory trait — not the call site — picks which.
+//!
+//! Both refinements compose into the `PersonaAdapterFactory` trait
+//! below without touching `materialize_adapters` itself. The trait
+//! line is where #122 + #108 land their respective decisions.
+//!
+//! ## Doctrine
+//!
+//! - [[no-fallbacks-ever]]: each slot is materialized independently;
+//!   failures are reported per-row. The supervisor never substitutes
+//!   a "default" adapter — a `Err(SupervisorError)` row stays errored
+//!   and the operator decides whether to refuse boot.
+//! - [[commands-are-dumb-daemons-are-smart]]: the factory trait is
+//!   trivial (one `build_adapter` method). Smart routing (which
+//!   factory? which backend?) lives in the boot composition above
+//!   this layer.
+//! - [[intent-driven-api-not-hot-patches]]: callers hand in a
+//!   `PersonaInferenceProfile` and get back a ready adapter. No magic
+//!   constants, no env-var probes — the profile is the substrate's
+//!   declared intent and the adapter materializes that.

+/// One row of the supervisor's roster — and the substrate's
+/// per-persona context object. Analog of Android's `Context`:
+/// the single struct every persona-scoped function reads from.
+///
+/// ## The `&ctx` doctrine
+///
+/// Persona/cognition/RAG/inference/supervisor functions take
+/// `&PersonaContext` and read what they need. They MUST NOT extract
+/// individual fields and pass them as separate arguments — that
+/// fragments the substrate's source of truth and creates drift.
+/// Every derived shape (a RAG inspection request, a sampling spec
+/// adjustment, a log scope) is produced from `&ctx` via a named
+/// constructor whose name says `for_persona`/`for_ctx`.
+///
+/// ## The substrate's actor model — this IS the airc user
+///
+/// Per `[[personas-are-citizens-airc-is-identity-provider]]`:
+/// "Personas, humans, Claude/OpenClaw/Hermes are the same kind of
+/// citizen." Every actor in the substrate is an airc user.
+///
+/// The substrate's eventual shape (task #142) is a `BaseUser` that
+/// carries the airc props every actor has — peer_id, identity,
+/// runtime, home, default_room — plus per-actor extensions:
+///   - `PersonaContext` = `BaseUser` + (role, profile, adapter)
+///   - `HumanUserContext` = `BaseUser` + UI session + human ID card
+///   - `WebUserContext` = `BaseUser` + tab/session id + auth scope
+///
+/// Same base, different extensions. Past designs that scattered
+/// actor state across multiple ad-hoc structs are explicitly the
+/// anti-pattern this struct exists to prevent (Joel 2026-06-02 —
+/// "design got out of control due to not using a shared object for
+/// all state info required for a persona OR user"). For slice 13,
+/// `PersonaContext` already carries the airc props (via `runtime`)
+/// + persona extensions — so the BaseUser extraction is purely a
+/// rename + trait extraction, additive only.
+///
+/// ## What's in the context
+///
+/// - `identity` — substrate-stable persona_id + airc-side
+///   peer_id/agent_name/home dir + the room she joined at bootstrap.
+/// - `role` — Helper / Coder / Sentinel / Custom. Cognition reads it
+///   to shape prompts.
+/// - `profile` — the inference shape: `context_length`, `n_ubatch`,
+///   sampling, `model_id`, `stop_sequences`, `chat_template`. The
+///   single source of truth for the persona's compute envelope.
+/// - `adapter` — the inference adapter, hot for generate_text. `Arc`
+///   so the service loop can clone-share it with the RAG layer.
+/// - `runtime` — the persona's `Arc<dyn AircCitizen>` (her grid
+///   presence). The service loop subscribes through this; `say()`
+///   posts through this. Cognition reads `runtime.peer_id()` for
+///   self-filtering. The trait abstraction (per slice 13.5 +
+///   `[[personas-are-citizens-airc-is-identity-provider]]`) means
+///   tests get a typed stub instead of an `Option`.
+///
+/// ## Type-alias note
+///
+/// The struct used to be named `HostedPersona` (slice 9). The rename
+/// to `PersonaContext` signals the design role; `pub type
+/// HostedPersona = PersonaContext;` below keeps slice-9-era callers
+/// compiling without a sweeping rename. New code should use

+// ─── Context trait impl ────────────────────────────────────────────────
+//
+// Per task #142 Slice 2 + [[airc-is-the-session-not-a-feature]]:
+// every actor on the substrate carries an `Identity` and an airc
+// citizen handle, reachable via the `Context` trait. `PersonaContext`
+// is the first concrete implementor; `StubContext`, `ClaudeContext`,
+// `JtagContext`, etc. follow the same shape.
+//
+// ## Transitional storage shape (Identity synthesized per call)
+//
+// `PersonaContext.identity` is still `PersonaInstanceInfo` (the
+// pre-Identity-entity struct). `Context::identity()` SYNTHESIZES an
+// `Identity` on each call, returning `Cow::Owned(synthesized)`. A
+// future slice migrates PersonaContext to store `Identity` directly;
+// the impl then becomes `Cow::Borrowed(&self.identity)` at zero cost.
+//
+// Per-call synthesis cost is acceptable per
+// [[substrate-overhead-is-1to3ms-LLM-dominates-latency]] — Uuid copy
+// + String clones are not the substrate's latency bottleneck.
+//
+// ## Identity Uuid — `ctx.identity().id` IS the registry key (Slice 1B)
+//
+// Slice 1B of #142 collapsed `PersonaInstanceInfo.persona_id ==
+// peer_id` at the runtime boundary (`PersonaAircRuntime::bootstrap`
+// + `from_attached` reseat the field from `airc.peer_id().as_uuid()`).
+// Callers may now safely use `ctx.identity().id` as a registry key
+// — it is the same Uuid as `ctx.identity.persona_id` and the same
+// Uuid as `airc.peer_id().as_uuid()`, per
+// [[persona-identity-derives-from-source-id]] (the cryptographic
+// keypair Uuid IS the substrate identity).

+//! `CognitionTrace` — per-turn time-series of every seam a persona's
+//! `respond()` call passes through.
+//!
+//! # Why this exists
+//!
+//! "We need our mechanic's meters, EE's oscilloscope, programmer's test
+//! bench, F1 racer's re-simulation, on every persona, isolatable at any
+//! level so we can replay or even use this to break and train."
+//! — Joel, 2026-04-22.
+//!
+//! `CognitionTrace` is the spine of that. Each seam in the cognition
+//! pipeline (analyze, prompt assembly, inference, post-process)
+//! appends a `TraceSeam` with its name, start time, duration, and
+//! seam-specific metadata. The completed trace serializes into the
+//! turn record alongside the request/response, so a captured trace +
+//! the captured request reconstructs WHAT happened AND HOW LONG each
+//! step took, no live system needed.
+//!
+//! # Design
+//!
+//! - **Value object, not a service**. Created per call, dropped per
+//!   call. No global state, no async machinery, no locks.
+//! - **Thread-affined**. Owned by the cognition turn that created it.
+//!   `respond()` is a `tokio::task` per persona; no two tasks share a
+//!   trace. Borrow it `&mut` through helper functions; no `Arc<Mutex>`
+//!   needed, no contention.
+//! - **Open-vocabulary metadata**. Each seam carries a
+//!   `serde_json::Value` of seam-specific fields (analyze records
+//!   `from_cache: bool`, inference records `model: String`, etc.).
+//!   Adding a new field doesn't touch the trace type.
+//! - **Source-time strings for seam names**. `&'static str` instead of
+//!   enum so new seams (recipe-specific later) don't require enum
+//!   churn. Cost: typo-by-string, mitigated by the seam-name constants
+//!   below.
+//!
+//! # Seam name conventions
+//!
+//! Use the constants in this module (`SEAM_*`) when emitting from the
+//! known cognition path. Recipe-specific seams (added in Phase B+)
+//! supply their own string at the call site.

+//! Per-turn shared context — fields identical across every persona
+//! responding to the same message in the same room.
+//!
+//! # Why hoist
+//!
+//! Before #1206, every persona's `RespondInput` carried its own deep
+//! copy of `recent_history`, `known_specialties`, and `room_id`. With
+//! N personas reacting to one message, that's N deep clones of
+//! identical data on the hot path — plus more clones inside
+//! `respond()` as the data flows through analyze → render → prompt
+//! assembly → recorder. The cost is O(N × history_depth × clone_cost)
+//! per turn, all of it pure waste.
+//!
+//! `Arc<TurnContext>` collapses this into a single allocation per
+//! turn that all personas share. Cloning the `Arc` is a single
+//! pointer-bump; cloning the `Vec` it wraps was a heap walk.
+//!
+//! # Why this struct (not just inline `Arc`s on each field)
+//!
+//! Grouping into one struct gives:
+//! - **One refcount** instead of three (smaller per-clone overhead).
+//! - **One construction site** in `build_respond_input` — the place
+//!   that knew how to assemble the per-turn shape can keep doing so
+//!   without hauling three `Arc::new` calls through the projection.
+//! - **A natural attach point for follow-up per-turn data** — the
+//!   #1211 PR-2 work (engram recall surface plumbed into
+//!   `prompt_assembly`) hangs off this struct. Each new per-turn
+//!   field gets one place to live, not a fresh `Arc<Vec<...>>`
+//!   field on every consumer.
+//!
+//! # Field selection
+//!
+//! Only fields that are *truly identical across personas in the same
+//! turn* belong here. Fields that differ per persona (`system_prompt`,
+//! `model`, `capabilities`, `other_persona_names` — which excludes
+//! the self-persona's name from the room roster) stay on
+//! `RespondInput`.

+//! `EventSubscribeAdapter` + `EventUnsubscribeAdapter` — the
+//! ConsumerAdapter shells that wire
+//! [`EventPublisherState`](super::EventPublisherState) into the
+//! airc adapter registry.
+//!
+//! These are thin shells around the pure functions in
+//! [`super::airc_event_publisher`]: parse the envelope via the
+//! relevant pure function, delegate to the state machine, build
+//! the ack via the relevant pure function, reply via
+//! `Airc::reply`. The interesting logic lives in the pure
+//! functions; the adapter is the wire-binding glue.
+//!
+//! ## Why two adapters, not one
+//!
+//! The airc adapter registry routes by `body_hint`. Subscribe and
+//! unsubscribe have distinct body hints
+//! ([`EVENT_SUBSCRIBE_BODY_HINT`] vs
+//! [`EVENT_UNSUBSCRIBE_BODY_HINT`]) so each needs its own
+//! ConsumerAdapter registration. They share an
+//! `Arc<EventPublisherState>` so unsubscribe targets the same
+//! registry subscribe populated.
+//!
+//! ## Composition at boot
+//!
+//! ```ignore
+//! use std::sync::Arc;
+//! use continuum_core::routing::{
+//!     EventPublisherState, EventSubscribeAdapter, EventUnsubscribeAdapter,
+//! };
+//!
+//! let state = Arc::new(EventPublisherState::new());
+//! let subscribe = EventSubscribeAdapter::new(airc.clone(), state.clone());
+//! let unsubscribe = EventUnsubscribeAdapter::new(airc.clone(), state.clone());
+//! airc.register_consumer_adapter(subscribe).await?;
+//! airc.register_consumer_adapter(unsubscribe).await?;
+//! ```
+//!
+//! After registration, every inbound
+//! `airc://<this-peer>/events/<topic>/subscribe` flows through
+//! `EventSubscribeAdapter` → `EventPublisherState::register` →
+//! ack reply. Mirrors `CommandRequestHandler`'s wire-binding
+//! exactly.

+//! `AircEventPublisher` — peer-side cross-grid event publisher.
+//!
+//! The inbound symmetric of [`AircEventTransport`](super::AircEventTransport).
+//! When a remote substrate dispatches
+//! `airc://<this-peer>/events/<topic>/subscribe`, its
+//! AircEventTransport packages an
+//! [`AircEventSubscribe`](super::AircEventSubscribe) envelope and
+//! sends via `Airc::request()`. The airc daemon on this side
+//! routes the envelope by body_hint to whichever ConsumerAdapter
+//! claims [`EVENT_SUBSCRIBE_BODY_HINT`]. That adapter wraps THIS
+//! publisher.
+//!
+//! ## What this commit ships
+//!
+//! This commit lands the **state machine + pure testable seams**:
+//!
+//! - [`EventPublisherState`] — the in-memory subscription registry.
+//!   Tracks active `(subscription_id → ActiveSubscription)` mappings
+//!   with subscriber peer, topic, filter, and a monotonic sequence
+//!   counter for drop-detection on the caller side.
+//! - [`register_subscription`](EventPublisherState::register) /
+//!   [`unregister_subscription`](EventPublisherState::unregister) /
+//!   [`lookup_matching`](EventPublisherState::lookup_matching) —
+//!   the three substrate primitives the ConsumerAdapters delegate
+//!   into.
+//! - Pure free functions: [`parse_subscribe_envelope`],
+//!   [`parse_unsubscribe_envelope`], [`build_subscribe_ack`],
+//!   [`build_unsubscribe_ack`], [`build_deliver_frame`],
+//!   [`matches_filter`] — every refusal/decision branch is
+//!   testable without airc, mirroring the testable-seams pattern
+//!   from `AircEventTransport` and `CommandRequestHandler`.
+//!
+//! ## What lands next
+//!
+//! - **`EventSubscribeAdapter`** + **`EventUnsubscribeAdapter`** —
+//!   thin `ConsumerAdapter` wrappers that parse via the pure
+//!   functions above, delegate to [`EventPublisherState`], and ack
+//!   via `Airc::reply()`. Both share an `Arc<EventPublisherState>`
+//!   so unsubscribe targets the same registry subscribe populated.
+//! - **`AircEventPublisher::publish(topic, payload)`** — fan-out
+//!   method. Looks up matching subscriptions via
+//!   `lookup_matching(topic, &payload)`, builds an
+//!   [`AircEventDeliver`] per subscriber (sequence bumped), sends
+//!   each as a room-broadcast `Airc::publish` with the
+//!   subscription_id header (subscribers demux via
+//!   `AircEventTransport::matches_subscription`).
+//! - Eventually: a local-`Events::emit()` bridge that calls
+//!   `publish()` automatically whenever a topic the substrate has
+//!   subscribers for fires. Until the local Events infrastructure
+//!   exists in continuum-core, the publish API is caller-driven —
+//!   intentionally simple, intentionally not auto-wired.
+//!
+//! ## Design choice: room-broadcast Deliver, header-demux at subscriber
+//!
+//! The airc transport addressing model is room-as-trust-boundary.
+//! `Airc::publish` broadcasts to the current room; subscribers
+//! demux by `HEADER_EVENT_SUBSCRIPTION_ID`. The same shape airc
+//! chat uses (everyone in the room sees the frame; addressing is
+//! semantic). Per-peer point-to-point is an optimization for a
+//! later slice, not a correctness need — subscription_id is a
+//! UUID, indistinguishable to non-subscribers.

+//! `AircEventTransport` — caller-side cross-grid event subscription.
+//!
+//! The event-side parallel of [`AircTransport`](super::airc_transport).
+//! When a substrate caller wants to subscribe to events on a remote
+//! peer, this transport packages an
+//! [`AircEventSubscribe`](super::AircEventSubscribe) envelope via
+//! `Airc::request`, awaits the
+//! [`AircEventSubscribeAck`](super::AircEventSubscribeAck), then
+//! exposes the per-subscription
+//! [`AircEventDeliver`](super::AircEventDeliver) frames as an
+//! ongoing stream.
+//!
+//! ## Same testable-seams pattern as `AircTransport`
+//!
+//! Per PR #1529 reviewer 3 fix: every refusal branch is factored as
+//! a `pub` free function so unit tests cover them without spinning
+//! up real airc. The `subscribe`/`unsubscribe` methods themselves
+//! are thin wrappers — request, await, decode via the free
+//! functions, return.
+//!
+//! Pure free functions (testable WITHOUT `Airc`):
+//!
+//! - [`Self::resolve_subscribe`] — build the outbound `MentionTarget` +
+//!   `Headers` + serialized `Body` for a subscribe request
+//! - [`Self::decode_subscribe_ack`] — unpack a reply body as
+//!   [`AircEventSubscribeAck`], surfacing typed errors for missing
+//!   body / binary body / malformed JSON
+//! - [`Self::resolve_unsubscribe`] — same for unsubscribe-request
+//! - [`Self::decode_unsubscribe_ack`] — same for unsubscribe-reply
+//! - [`Self::decode_deliver_frame`] — extract an
+//!   [`AircEventDeliver`] from an inbound `TranscriptEvent`, or
+//!   typed error
+//! - [`Self::matches_subscription`] — pure predicate: does this
+//!   `TranscriptEvent` belong to a given subscription_id? Used to
+//!   filter the airc event stream into a per-subscription view
+//!

+//!   configurable deadline.
+//! - The 6 pure free functions above + their unit tests.
+//! - `subscribe(target_peer, topic, filter)` — sends the subscribe
+//!   request via `Airc::request`, awaits ack, returns
+//!   [`EventSubscription`] carrying the subscription_id and a
+//!   `tokio::sync::mpsc::Receiver<AircEventDeliver>` that yields
+//!   matching delivery frames.
+//! - `unsubscribe(target_peer, subscription_id)` — sends the
+//!   unsubscribe request, awaits ack, returns whether the peer
+//!   considered the subscription active.
+//!
+//! ## What lands next
+//!
+//! - **Peer-side event publisher** — `ConsumerAdapter` registered
+//!   against `EVENT_SUBSCRIBE_BODY_HINT`. Mints subscription_id on
+//!   receiving subscribe, registers locally, subscribes to local
+//!   `Events::emit()` for matching topics, fans out as
+//!   `AircEventDeliver` frames to the subscriber's peer_id.
+//! - **`Transport` trait extension** — adds `subscribe()` method so
+//!   the dispatcher's match can route subscription URIs (e.g.
+//!   `airc://<peer>/events/<topic>/subscribe`) through this
+//!   transport via the same chain as commands.
+//! - **`Events::subscribe::<E>(uri)` typed consumer API** — the row
+//!   above wire-level; turns `Events::subscribe::<ChatMessages>(uri)`
+//!   into a typed `EventStream<ChatMessage>`.
+//! - **LAN-loopback integration test** — paired with the command
+//!   surface integration test (#188) once `TwoAircLoopback` fixture
+//!   lands.

+//! `AircTransport` — real cross-grid `Transport` impl over airc-lib's
+//! request/reply command bus.
+//!
+//! When the operator installs this transport via
+//! `CommandExecutor::with_remote_transport(Arc::new(AircTransport::new(airc)))`,
+//! every non-Local [`RouteDecision`] flows through here:
+//!
+//! 1. [`command_request_from_route_decision`] packages the typed
+//!    decision into the wire envelope
+//! 2. The envelope serializes as a [`Body::Json`]
+//! 3. Headers are stamped (path, kind, env, body_hint) so middleware
+//!    can filter without parsing the body
+//! 4. `Airc::request(target, headers, body, deadline)` sends the
+//!    frame; airc-lib auto-stamps correlation_id + reply_to + deadline
+//! 5. `Airc::await_reply(pending)` waits for the matching reply
+//! 6. The reply's body decodes as [`AircCommandResponse`] which
+//!    collapses to `Result<Value, String>` via `into_result()`
+//!
+//! ## What this commit ships
+//!
+//! - [`AircTransport`] struct holding `Arc<airc_lib::Airc>` + default
+//!   deadline
+//! - `Transport` impl handling:
+//!   - [`RouteDecision::Peer`] with [`PeerRef::Uuid`] — full
+//!     send-and-await, the canonical cross-grid path
+//!   - [`RouteDecision::Peer`] with [`PeerRef::Name`] — typed error
+//!     pointing at the airc-side whois resolver (separate slice)
+//!   - [`RouteDecision::Broadcast`] — wires to `MentionTarget::All`,
+//!     first-reply-wins semantics
+//!   - [`RouteDecision::Room`] — typed not-yet-implemented (room
+//!     broadcast needs distinct semantics: all-replies-collect vs
+//!     fire-and-forget; that decision belongs in its own slice)
+//!   - [`RouteDecision::Local`] — loud BUG error (dispatcher routes
+//!     Local inline; remote transport should never see it)
+//!
+//! ## What lands in the follow-up commits
+//!
+//! - **Peer-side command handler** — subscribes to events whose
+//!   body_hint matches [`COMMAND_REQUEST_BODY_HINT`], decodes the
+//!   envelope, dispatches via local `CommandExecutor` (threading
+//!   `CallerIdentity::airc(verified_sender)` into the policy gate),
+//!   replies via `Airc::reply()` with [`AircCommandResponse`].
+//!
+//! - **End-to-end integration test** — two `Airc` instances in
+//!   process talking over a LAN socket. Persona A dispatches a
+//!   command at `airc://<peer-b>/code/exists`; Persona B's handler
+//!   runs it locally; the typed result flows back.
+//!
+//! - **Fake-local-grid integration test** — substrate-internal
+//!   simulation: N `CommandExecutor` instances in process, a
+//!   `LocalGridTransport` shuttling decisions between them. Same
+//!   typed wire shape, no airc daemon, no LAN socket. Proves the
+//!   dispatcher logic for multi-peer scenarios at unit-test speed.
+//!
+//! ## Why typed errors per variant
+//!
+//! Each non-implemented variant returns an error that names the
+//! specific missing piece. An operator dispatching `airc://maya/...`
+//! against a name (no UUID) sees `"peer-name resolution not yet
+//! wired — use a peer UUID, or wait for the whois slice"`. They
+//! don't see a generic "not implemented" — they see exactly what
+//! to do or wait for. Same compression as the rest of Slice P:
+//! errors carry their actionable cause.

+//! `AuthPolicy` — the substrate's typed auth gate.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` §"Auth gate":
+//! every URI passes through ONE chokepoint where a typed policy
+//! evaluates whether the caller may execute. Today's variants
+//! cover the local dispatch path; cross-grid callers carry their
+//! peer identity via the airc envelope once the transport layer
+//! lands.
+//!
+//! ## The shape
+//!
+//! ```ignore
+//! trait AuthPolicy: Send + Sync {
+//!     fn gate(&self, decision: &RouteDecision, caller: Option<&CallerIdentity>) -> Verdict;
+//! }
+//! ```
+//!
+//! The dispatcher calls `gate()` between `route()` and the variant
+//! match. The returned [`Verdict`] (Allowed / Forbidden / Deferred)
+//! determines whether dispatch proceeds, returns a typed refusal,
+//! or queues a consent prompt.
+//!
+//! ## Why a trait
+//!
+//! Three near-term consumers:
+//!
+//! 1. **`AllowAllPolicy`** (default) — substrate ships with no
+//!    policy curation; every dispatch is allowed. Existing callers
+//!    and tests don't break, and operators opt in to real
+//!    policy by replacing the trait impl at boot.
+//!
+//! 2. **`ClosurePolicy`** — test/fixture impl that delegates to a
+//!    closure. Substrate-side test cases lease this instead of
+//!    spinning up a full policy database.
+//!
+//! 3. **ORM-backed policy** (follow-up) — looks up `(caller_peer_id,
+//!    uri_pattern)` rows in the substrate's policy table and
+//!    returns the typed verdict. Swaps in via the same trait.
+//!
+//! Adding the cross-grid auth flow (peer signature verification,
+//! capability tokens, sentinel quorum) lands as a fourth impl when
+//! its slice arrives; the trait signature doesn't move.
+//!
+//! ## Caller identity
+//!
+//! Today's [`CallerIdentity`] is intentionally minimal:
+//!
+//! ```ignore
+//! pub struct CallerIdentity {
+//!     pub peer_id: Uuid,
+//!     pub source: CallerSource,
+//! }
+//! ```
+//!
+//! Local dispatches today pass `None` for the caller — this substrate's
+//! own code invoking commands on itself, which the default
+//! `AllowAllPolicy` lets through. Cross-grid dispatches will populate
+//! `Some(CallerIdentity { peer_id: airc_sender, source: CallerSource::Airc })`
+//! when the transport layer extracts the sender from the envelope.
+//!
+//! Future fields (capability claims, signed tokens, session context)
+//! land additively — `#[non_exhaustive]` keeps the struct extensible
+//! without breaking external impls.

+//! claims [`COMMAND_REQUEST_BODY_HINT`]. That adapter is this handler.
+//!
+//! The handler:

+//! 1. Parses the [`TranscriptEvent`] to extract:

+//!    - **Reply addressing** (`airc.reply_to` + `airc.correlation_id`
+//!      headers, auto-stamped by `Airc::request()`)
+//!    - **Typed request body** ([`AircCommandRequest`])
+//!
+//! 2. Constructs a local [`CommandUri`] from the request's path. The
+//!    path the remote substrate dispatched maps 1:1 to a local URI;
+//!    auth + routing decisions happen locally based on the local
+//!    substrate's policy.

+//! 3. Builds a [`CallerIdentity::airc(verified_sender)`] and threads
+//!    it through [`CommandExecutor::execute_with_caller`]. The local
+//!    [`AuthPolicy`](crate::routing::AuthPolicy) gate sees the real
+//!    remote caller and applies the right verdict — Allowed,
+//!    Forbidden (with typed reason), or Deferred.
+//!
+//! 4. Packages the result as [`AircCommandResponse`] — Ok with the
+//!    JSON result OR Error with the typed message. Errors here might
+//!    come from the gate (Forbidden / Deferred), from the module
+//!    handler, or from the substrate itself; the caller-side
+//!    AircTransport propagates the message into the local
+//!    `Result<CommandResult, String>` shape exactly.
+//!
+//! 5. Replies via `Airc::reply()` with [`HEADER_COMMAND_STATUS`] +
+//!    [`HEADER_CONTINUUM_BODY_HINT`] stamped on the headers (so
+//!    middleware can filter responses without parsing bodies, same
+//!    property as the request path).
+//!
+//! ## Why typed errors flow through the wire
+//!
+//! Per [[no-fallbacks-ever]]: a Forbidden verdict on the remote
+//! substrate becomes an `Error { message: "forbidden: NoPermissionForUri(...)" }`
+//! on the wire, becomes `Err("forbidden: ...")` on the caller side,
+//! becomes the substrate's typed `SubstrateError::Forbidden(...)` at
+//! the typed-consumer layer. The caller can match on the variant and
+//! decide how to recover — locally or by surfacing to the user.
+//!
+//! ## Composition at boot
+//!
+//! ```ignore
+//! use std::sync::Arc;
+//! use continuum_core::routing::CommandRequestHandler;
+//!
+//! let handler = CommandRequestHandler::new(airc.clone(), executor.clone());
+//! airc.register_consumer_adapter(handler).await?;
+//! ```
+//!
+//! After registration, every inbound `airc://<this-peer>/<path>`
+//! dispatch flows through this handler → local CommandExecutor →
+//! local AuthPolicy → local module → reply. Symmetric with the
+//! AircTransport's outbound path.

+//! `CommandUri` — the substrate's typed addressing primitive.
+//!
+//! Implements the Slice P grammar
+//! `airc://[peer[@node]][:env]/[path][?query][#fragment]`. See
+//! `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` for the
+//! design contract.
+//!
+//! ## Variants partition by what's being addressed
+//!
+//! - [`CommandUri::Local`] — caller's substrate. Bare paths
+//!   (`"inference/llm/generate"`) and the explicit-local form
+//!   (`"airc:///inference/llm/generate"`) both parse here.
+//! - [`CommandUri::Peer`] — a specific peer with optional node
+//!   disambiguation and optional environment filter.
+//! - [`CommandUri::Room`] — broadcast to a room (UUID-addressed),
+//!   optional env filter.
+//! - [`CommandUri::Broadcast`] — broadcast to every active env of
+//!   a peer (the `:*` wildcard form). Kept as its own variant so the
+//!   dispatcher can choose a specialized broadcast transport path.
+//!
+//! ## Round-trip guarantee
+//!
+//! For every valid input that parses successfully,
+//! `CommandUri::parse(&uri.to_string()) == Ok(uri.clone())`. The
+//! [`round_trip_*`](#tests) tests pin this for every variant.
+//!
+//! ## Naming convention
+//!
+//! `room` is a reserved peer-name prefix sigil — a URI authority
+//! starting with `room:` parses to [`CommandUri::Room`], NOT a
+//! peer named `room`. Operators who want to literally name a
+//! persona `room` must use the canonical UUID form. The collision
+//! is documented in the design doc and enforced here at parse time.

+//! `EnvironmentId` — the typed embodiment dimension of the URI grammar.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` (Slice P): the
+//! `:env` component of `airc://<peer>[:env]/<path>` selects which
+//! presentation context handles the dispatch. An actor can have
+//! multiple environments active simultaneously (Joel's browser tab,
+//! VR headset, terminal session all live at once); this type names
+//! them.
+//!
+//! ## Variants
+//!
+//! - [`EnvironmentId::Named`] — specific environment by name. The
+//!   well-known names (`web`, `tty`, `cli`, `vr`, `ar`, `headless`)
+//!   are convention; the type accepts any non-empty string so
+//!   custom envs slot in without substrate changes.
+//! - [`EnvironmentId::Wildcard`] — match every active environment
+//!   of the target. Used by broadcast dispatch (the `:*` URI form).
+//!
+//! ## Custom env naming convention
+//!
+//! Per the design doc's open-questions resolution lean: custom env
+//! names SHOULD be prefixed with `x-<vendor>-<name>` (e.g.
+//! `x-cambriantech-bevy-rig`) to avoid colliding with future
+//! well-known names. The parser doesn't enforce the prefix today;
+//! enforcement lands when the env registry adds collision detection.

+//! Mechanic-grade observability macros — Slice P deliverable 12, 14, 15.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md`:
+//!
+//! - [`probe!`] — structured measurement emit with per-class routing
+//!   (`class = "latency" | "decision" | "state" | "admission" | ...`).
+//!   Conventional Rust tracing macros (`debug!`, `info!`, ...) stay
+//!   conventional; `probe!` exists only because of features they
+//!   don't have: per-class routing, ALWAYS-ON intent, replay
+//!   persistence, sample-rate configurable, aggregation-ready.
+//! - [`time!`] — explicit-block timing as a one-line macro. Wraps a
+//!   `tracing::info_span!` around the supplied block / expression so
+//!   the span's duration becomes a timing probe automatically.
+//!
+//! Joel: "macros are easy and a way of preventing misuse. If coding
+//! timing or logging is painful it won't happen." The macro shape
+//! mirrors `tracing::*` so developers reach for the familiar idiom;
+//! the substrate's tracing subscriber does the URI-tagging + probe
+//! routing without any per-call-site wiring.
+//!
+//! ## Zero-cost-when-disabled property
+//!
+//! Both macros expand to `tracing::event!` / `tracing::info_span!`
+//! calls that inherit `tracing`'s `release_max_level_*` cargo
+//! feature gates. When the level is filtered out at build time,
+//! the expansion is literally absent from the binary — no
+//! formatting, no allocation, no branch. The compiler discipline
+//! the design doc names is enforced by sticking to the same
+//! `tracing` shape every conventional macro uses.
+
+/// Structured measurement emit. Routes by the `class` field to the
+/// per-class probe stream `airc://<actor>/debug/probes/<class>/stream`.
+///
+/// Shape mirrors `tracing::info!` for muscle memory:
+///
+/// ```ignore
+/// use continuum_core::probe;
+///
+/// // Minimum: just a class and a message
+/// probe!(class = "latency", "turn complete");
+///
+/// // Typical: class + structured fields + optional message
+/// probe!(class = "latency",   turn_id = %id, duration_ms = elapsed, "turn complete");
+/// probe!(class = "decision",  action = "evict-lora", target = "typescript-expertise");
+/// probe!(class = "state",     working_set_size = ws.len());
+/// probe!(class = "admission", lane = 3, verdict = "accepted", "admitted");
+/// ```
+///
+/// Routing key is the `class` field. Substrate's tracing subscriber
+/// inspects the event's `class` field and routes the captured
+/// record to `airc://<actor>/debug/probes/<class>/stream`. URI-tag
+/// for the actor comes from the current span context (the dispatch
+/// span the executor establishes).
+///
+/// Implemented as a tracing event at `Level::INFO` so it composes
+/// with the existing tracing pipeline. Future commits gate per-class
+/// emission on a cargo feature so production builds compile out
+/// disabled classes entirely.
+#[macro_export]
+macro_rules! probe {
+    // probe!(class = "foo", field = val, ..., "message format" args...)
+    (class = $class:expr, $($rest:tt)*) => {
+        ::tracing::event!(
+            ::tracing::Level::INFO,
+            probe_class = $class,
+            $($rest)*
+        )
+    };
+}
+
+/// Explicit-block timing for **synchronous** code. Wraps a block or
+/// expression in an `info_span!` whose duration becomes a timing
+/// probe at scope exit.
+///
+/// **MUST NOT contain `.await`.** Holding the `_enter` span guard
+/// across `.await` breaks the URI ancestry stack (the same async
+/// anti-pattern the `d1cf19dc5` dispatch fix was specifically about).
+/// For async bodies, use [`time_async!`] instead — it wraps the body
+/// in `.instrument(span).await` which trips span enter/exit at
+/// suspension boundaries correctly.
+///
+/// Per PR #1529 reviewer 2: the original `time!` was a substrate-wide
+/// foot-gun because `time!("infer", run_inference(...).await)` (a
+/// common shape) silently broke `URI_STACK` across the await. Split
+/// into typed sync/async variants per the dispatch fix doctrine.
+///
+/// ```ignore
+/// use continuum_core::time_sync;
+///
+/// // Block form — returns the block's value
+/// let candidates = time_sync!("recall_phase", {
+///     recall_candidates_blocking(&query)
+/// });
+///
+/// // Single-expression form (the most common shape)
+/// let result = time_sync!("hash_payload", compute_hash(&payload));
+/// ```
+///
+/// The span name becomes the `seam` field on the timing probe (the
+/// same field `time_probe!` uses — both macros agree so `jq` queries
+/// like `.fields.seam == "recall_phase"` match either kind). Same
+/// subscriber that routes `probe!` events handles span durations and
+/// routes to `airc://<actor>/debug/probes/timing/stream`. The
+/// dispatch span the executor establishes is the parent — so the
+/// timing probe's URI context is whatever URI was being dispatched.
+///
+/// When `time_sync!` is used outside any active dispatch span (e.g.
+/// in bootstrap code before the executor is wired), the span has no
+/// URI parent and the timing probe routes to the substrate's
+/// `bootstrap` virtual actor.
+#[macro_export]
+macro_rules! time_sync {
+    ($name:expr, $body:expr) => {{
+        let __span = ::tracing::info_span!(
+            "time",
+            seam = $name,
+            probe_class = "timing",
+        );
+        let __enter = __span.enter();
+        $body
+    }};
+}
+
+/// Explicit timing for an **async future** — safe-by-construction
+/// companion to [`time_sync!`].
+///
+/// Per Joel 2026-06-06 `[[refine-tools-as-you-use-them]]`: every
+/// async timing site in the cognition path was an
+/// `.instrument(info_span!("time", name=..., probe_class="timing"))
+/// .await` ceremony. Three lines plus a `use tracing::Instrument`
+/// import. Nobody writes those when adding a new seam in a hurry —
+/// the result was that async cognition stages stayed untimed. This
+/// macro collapses that to one line.
+///
+/// ```ignore
+/// use continuum_core::time_probe;
+///
+/// // Wrap any future expression:
+/// let analysis = time_probe!("cognition.analyze", analyze(input));
+///
+/// // Inline complex expressions just as cleanly:
+/// let response = time_probe!("inference.generate",
+///     adapter.generate_text(request));
+/// ```
+///
+/// ## Why this isn't `time_async!`
+///
+/// The name `time_async!` is taken by `crate::logging::time_async!`
+/// which has a DIFFERENT shape (RAII `TimingGuard` with
+/// `category` + `operation`, NOT a tracing span). The two
+/// macros serve different observability paths — RAII to the
+/// logging crate's own logger vs tracing-span to the substrate's
+/// probe routing. Keeping distinct names prevents accidental
+/// substitution.
+///
+/// ## Why this is safe across `.await`
+///
+/// The previous substrate-wide foot-gun (PR #1529 reviewer 2 fix)
+/// was a `time!` macro that expanded to `let _enter = span.enter();
+/// $body` where `$body` contained `.await`. Holding `_enter` across
+/// `.await` broke `URI_STACK`. THIS macro expands to
+/// `$future.instrument(span).await` — the future itself enters /
+/// exits the span via `Future::poll` boundaries, never holding a
+/// scope guard across an await suspension. Same shape
+/// `CommandExecutor::dispatch` uses (per the `d1cf19dc5` fix).
+///
+/// ## Where it lands
+///
+/// Emits the same `timing` probe class as `time_sync!`. Operators
+/// filter both sync + async timings together via
+/// `CONTINUUM_PROBE_CLASSES=timing` and see one flat timeline.
+///
+/// **Substrate gaps tracked separately:** task #196 (probe Layers
+/// only implement `on_event`, not `on_close` — span-close events
+/// from `time_sync!` + `time_probe!` don't yet reach the JSONL log
+/// or broadcast subscribers; the call shape lands here, the
+/// routing side follows). Task #197 (flat `timing` class vs the
+/// substrate's hierarchical class taxonomy — picking the
+/// convention is its own design decision). Don't rely on the
+/// timing probe being persistable until #196 lands.
+///
+/// ## Cost
+///
+/// Low — but NOT zero. `info_span!` allocates a `Span` struct +
+/// attaches the `name` + `probe_class` fields regardless of
+/// whether a subscriber is registered. `Instrumented<F>` wraps
+/// the future, adding ~24 bytes per call site and one branch on
+/// every `poll`. Tracing's `release_max_level_*` cargo features
+/// compile out the `event!` body, but the `Instrumented<F>`
+/// wrapper persists at runtime even at max-level-off. Acceptable
+/// for cognition seams (Qwen inference dominates wall-clock by
+/// 4-5 orders of magnitude); audit per task #198 if sprinkled
+/// into a hot loop.
+///
+/// ## Field names
+///
+/// The span carries `seam = $name` (the seam identifier as a
+/// dotted path, e.g. `"cognition.analyze.inference"`) and
+/// `probe_class = "timing"`. `seam` is chosen over the more-
+/// natural `name` to avoid field-name collision with other
+/// probes that already use `name` for different purposes
+/// (`probe!(class="state", name="active_persona", ...)`). All
+/// `jq` queries should filter on `.fields.seam`.

+///
+/// The substrate's spans form a tree; the URI-aware tracing
+/// [`UriCaptureLayer`](crate::routing::UriCaptureLayer) walks the
+/// current scope's ancestry and emits one frame per entered span
+/// carrying a `uri` field. The result is the URI path from the
+/// outermost dispatched command (the dispatch span the executor
+/// establishes) to whatever scope `stack!()` is called from.
+///
+/// ```ignore
+/// use continuum_core::{stack, probe};
+///
+/// // Typical pattern: attach the URI stack to an error probe so the
+/// // operator looking at /debug/probes/error/stream sees the chain
+/// // of dispatches that led to the failure
+/// probe!(class = "error", stack = ?stack!(), "engram lookup failed");
+/// ```
+///
+/// ## With the Layer installed (the substrate's wired path)
+///
+/// Returns the full URI ancestry, outermost first. The Layer must be
+/// installed at boot via
+/// `tracing_subscriber::registry().with(UriCaptureLayer::new()).init()`.
+///
+/// ## Without the Layer (bootstrap, third-party tools, tests)
+///
+/// Returns an empty `Vec` rather than fabricating a fake frame.
+/// Consumers handle the empty case (`if stack.is_empty() { ... }`).

+//! Substrate-wide grid routing primitives — the universal addressing
+//! layer every consumer (commands, events, debug, observability)
+//! reaches through.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` (Slice P):
+//! every load-bearing operation has a `CommandUri` address; the same
+//! grammar serves command dispatch, log-event tagging, debug pokes,
+//! probe stream routing, and event subscription. ONE primitive, N
+//! consumers — Joel's compression principle applied to the
+//! substrate's outermost surface.
+//!
+//! This module currently exposes:
+//! - [`CommandUri`] — the typed enum for the grammar
+//!   `airc://[peer[@node]][:env]/[path][?query][#fragment]`
+//! - [`PeerRef`], [`NodeId`], [`EnvSelector`], [`UriParseError`] —
+//!   the typed components
+//! - parser + `Display` round-trip
+//!
+//! Future commits add: dispatcher hooks (`Commands.execute()` accepts
+//! `CommandUri` OR bare path), transport selection
+//! (`route(uri) -> TransportDispatch`), auth gate (typed `Verdict`),
+//! tracing-span URI propagation, `/debug/` namespace routing,
+//! `probe!`/`time!`/`stack!` macros, and the env registry +
+//! `Context::environment()` accessor.

+//! Offline-debug JSONL sink for `probe!` events.
+//!
+//! ## Why this layer exists
+//!
+//! [`ProbeRouterLayer`](super::probe_router::ProbeRouterLayer) fans
+//! probe events to in-process broadcast subscribers (the
+//! `debug/probes/{class}/stream` URI consumers from Slice P, #177).
+//! That's perfect for substrate code that subscribes from another
+//! ServiceModule — but it disappears the moment the process exits.
+//!
+//! Joel's RTOS-debugger framing (2026-06-06,
+//! `[[jtag-probes-are-rtos-debugger]]`): a probe is a non-blocking
+//! breakpoint with variable inspection + timing. To "hunt down
+//! bottlenecks" or "track down stuff like [silence-affordance]
+//! bugs" you need the breakpoint history persisted across runs,
+//! filterable per-class, and `tail -f`-able from a shell. This
+//! layer provides exactly that.
+//!
+//! ## Shape
+//!
+//! Plain JSON-Lines on disk. One ProbeEvent per line. Each event
+//! gains a `captured_at_ms` field at sink time so log lines are
+//! self-dating without the caller threading clocks.
+//!
+//! ## Configuration
+//!
+//! Two env vars — operator-friendly, zero-recompile:
+//!
+//! - `CONTINUUM_PROBE_DIR=/path/to/probes.jsonl` — append-only file.
+//!   Unset = sink absent. The directory must exist (sink errors on
+//!   open if not; honest failure beats silent drop per
+//!   `[[no-fallbacks-ever]]`).
+//! - `CONTINUUM_PROBE_CLASSES=persona,cognition.analyze` — comma-
+//!   separated allowed-classes filter. Each value is matched against
+//!   each probe's class field by ONE of three rules:
+//!
+//!     1. `*` — wildcard, matches every class. Use when you want to
+//!        capture EVERYTHING and filter offline with `jq`.
+//!     2. Exact match — `cognition.analyze.parse` matches only
+//!        `cognition.analyze.parse`.
+//!     3. Namespace prefix — `persona` matches `persona.turn.spoke`,
+//!        `persona.response.enter`, etc. (the `persona.` prefix), but
+//!        does NOT match a hypothetical `personality.x`. Concretely
+//!        the rule is `class == filter || class.starts_with(filter + ".")`.
+//!
+//!   Same convention as tracing's `RUST_LOG`. Empty / unset = ALL
+//!   classes pass (file sink with no filter = full capture). Per
+//!   `[[no-fallbacks-ever]]`: `*` is the EXPLICIT all-classes
+//!   value; an empty filter set is a deliberate "no filter
+//!   configured."
+//!
+//! ## Output format
+//!
+//! ```jsonl
+//! {"captured_at_ms":1717689000123,"class":"persona.render.exit","uri_chain":["airc:///cognition/respond"],"message":"rendered","fields":{"persona":"Paige","prompt_len":"4823","decision":"Spoke"}}
+//! ```
+//!
+//! Greppable, filterable with `jq`, replay-able by feeding the
+//! lines back through `ProbeEvent` deserialization. Same shape the
+//! broadcast subscribers see, plus the timestamp.
+//!
+//! ## Performance
+//!
+//! Single `Mutex<BufWriter<File>>` per sink. Probes are not on the
+//! hot path of cognition (the LLM call dominates by 4-5 orders of
+//! magnitude); the lock contention from N persona loops writing
+//! one line per turn is dwarfed by the inference cost. If the
+//! substrate ever needs lock-free sink the right shape is per-class
+//! channels + dedicated writer task — same pattern
+//! `ProbeRouterLayer` already uses. Not load-bearing today.

+//! `ProbeRouterLayer` — the substrate's per-class event fanout.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` §"Per-class
+//! routing": every [`probe!`](crate::probe) call emits a
+//! `tracing::Event` carrying a `probe_class` field. This Layer
+//! intercepts those events, captures the substrate's URI ancestry via
+//! [`current_uri_chain`](crate::routing::current_uri_chain), and
+//! forwards a structured [`ProbeEvent`] to whoever is subscribed to
+//! that class — sentinels, Ares' dispatcher, the operator running
+//! `./jtag airc://maya/debug/probes/decision/stream`.
+//!
+//! ## Composition with `UriCaptureLayer`
+//!
+//! Install BOTH Layers at substrate boot:
+//!
+//! ```ignore
+//! use tracing_subscriber::prelude::*;
+//! use continuum_core::routing::{ProbeRouterLayer, UriCaptureLayer};
+//!
+//! let router = ProbeRouterLayer::new();
+//! let mut decisions = router.subscribe("decision");
+//!
+//! tracing_subscriber::registry()
+//!     .with(UriCaptureLayer::new())
+//!     .with(router)
+//!     .init();
+//!
+//! // ... persona code emits `probe!(class = "decision", ...)` events;
+//! // `decisions.recv().await` yields each one in turn.
+//! ```
+//!
+//! The router doesn't depend on `UriCaptureLayer` to compile — it
+//! calls `current_uri_chain()` which returns `Vec::new()` if no
+//! UriCapture Layer is installed. But in production both are present
+//! so each `ProbeEvent` carries the URI ancestry of the dispatch that
+//! produced it.
+//!
+//! ## Why a broadcast channel
+//!
+//! Multiple consumers per class are the common case: a sentinel
+//! watching `latency` for SLO breach AND the operator tailing the
+//! same stream during an incident AND a foundry fitness loop scoring
+//! every event. `tokio::sync::broadcast` lets all of them see every
+//! event without coordination.
+//!
+//! Lagged consumers (channel full because they fell behind) get
+//! `RecvError::Lagged` from `recv()` — that's `tokio::sync::broadcast`
+//! signaling honest pressure, not the router losing events silently.
+//! Substrate consumers handle Lagged the same way they handle any
+//! other backpressure signal (drop oldest, alert, scale capacity).
+//!
+//! ## Why register classes lazily
+//!
+//! Probes fire from anywhere — the router can't know up-front which
+//! classes the running personas will emit. Subscribing to a class
+//! creates the broadcast channel if it doesn't exist yet; firing a
+//! probe for a class no one's subscribed to is a cheap HashMap miss,
+//! no allocation, no send. That's the substrate's contribution to
+//! the [[no-fallbacks-ever]] principle applied to telemetry:
+//! unsubscribed classes don't get fabricated consumers, they just
+//! don't fire.

+//! Shared `probe_class`-carrying span machinery for the two
+//! consumer Layers ([`ProbeRouterLayer`](super::probe_router) +
+//! [`JsonlProbeFileSink`](super::probe_file_sink)).
+//!
+//! ## Why this module exists
+//!
+//! Both Layers want the SAME thing from a `time_sync!` /
+//! `time_probe!` span:
+//!
+//! 1. At `on_new_span`: figure out if this span carries a
+//!    `probe_class` attribute. If not, drop it on the floor. If
+//!    yes, capture the start `Instant` + the other fields so the
+//!    timing record can be built when the span closes.
+//! 2. At `on_close`: convert the parked metadata into a
+//!    [`ProbeEvent`](super::probe_router::ProbeEvent) carrying a
+//!    `duration_ms` field.
+//!
+//! Originally each Layer implemented its own visitor + struct +
+//! lifecycle hooks (~60 lines × 2). The reviewer-mandate review of
+//! PR #1541 caught three real costs:
+//!
+//! - **Per-span allocator pressure on the LCD floor (Joel's Intel
+//!   Mac).** `on_new_span` fires for EVERY tracing span the
+//!   substrate emits — tokio executor spans, framework spans, every
+//!   plain `info_span!`. Each Layer was allocating a visitor +
+//!   walking ALL fields with `format!("{:?}", value)` per field
+//!   before discarding because `probe_class` was missing. This file
+//!   adds [`span_carries_probe_class`] as the cheap up-front check
+//!   so non-probe spans cost ~10ns instead of one HashMap +
+//!   per-field format dispatch.
+//!
+//! - **Doubled cost when both Layers are installed.** Both Layers
+//!   independently visited the same span. This file's
+//!   [`ensure_probe_meta`] is idempotent: the first Layer to see
+//!   the span populates the extension; the second Layer finds it
+//!   already present and skips the visitor altogether.
+//!
+//! - **Timing drift between Layers.** Each Layer captured its own
+//!   `Instant::now()` at `on_new_span` and computed its own
+//!   `duration_ms` at `on_close`. Same span, two slightly different
+//!   numbers on the broadcast stream vs the JSONL log.
+//!   [`ensure_probe_meta`] inserts ONE `start: Instant` into the
+//!   extension; [`take_probe_meta`] reads it ONCE; both Layers see
+//!   the same number.
+//!
+//! ## Doctrine
+//!
+//! Per [[no-fallbacks-ever]]: spans without `probe_class` get
+//! ZERO allocation cost — the cheap metadata check returns `false`
+//! before any visitor work happens. We do not fabricate timing
+//! events for spans nobody asked to time.
+//!
+//! Per [[refine-tools-as-you-use-them]]: this module emerged from
+//! adversarial review of PR #1541. The substrate gets refined as
+//! it's used — the duplication that looked acceptable at N=2 was
+//! actually load-bearing at the Intel-Mac floor.

+//! `RouteDecision` — the substrate's typed answer to "what should
+//! happen with this URI?"
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` §"Transport
+//! selector": every dispatched [`CommandUri`] goes through one pure
+//! function — [`route`] — that returns a `RouteDecision`. The
+//! decision is exhaustive: every URI shape maps to exactly one
+//! variant, and the dispatcher's match handles each.
+//!
+//! This is the substrate's seam between the addressing layer and
+//! the transport layer. Today's variants:
+//!
+//! - [`RouteDecision::Local`] — execute in this substrate, walk the
+//!   existing interceptor + module + TS-fallback chain.
+//! - [`RouteDecision::Peer`] — route to a specific peer via airc
+//!   (transport implementation lands separately).
+//! - [`RouteDecision::Room`] — broadcast to subscribers of an airc
+//!   room.
+//! - [`RouteDecision::Broadcast`] — fan-out to every active env of a
+//!   peer (the `:*` wildcard form).
+//!
+//! ## Why a typed enum and not (e.g.) a `String` transport name
+//!
+//! Joel's compression principle applied to routing: ONE enum shape,
+//! every consumer's match is exhaustive, the compiler enforces that
+//! adding a new variant breaks every site that didn't update.
+//! Strings or untyped routing tags would let a future transport
+//! sneak past the dispatcher without anyone noticing — exactly the
+//! drift Slice P is fighting.
+//!
+//! ## What this commit lands
+//!
+//! - The `RouteDecision` enum
+//! - The pure `route(&CommandUri) -> RouteDecision` function
+//! - 100% mapping coverage — every `CommandUri` variant maps to
+//!   exactly one `RouteDecision` variant
+//! - Tests pinning the mapping
+//!
+//! ## What lands in the follow-up commits
+//!
+//! - **Auth gate** — `gate(decision, caller_peer_id) -> Verdict`
+//!   consults policy and returns Allowed / Forbidden / Deferred
+//!   BEFORE the decision reaches transport. Reuses
+//!   [`Verdict`](super::Verdict) (already a typed enum).
+//! - **Transport implementation** — `LocalTransport` + future
+//!   `AircTransport` implement a common `Transport` trait; the
+//!   dispatcher's match calls into the right one based on the
+//!   decision. Today's `CommandExecutor::execute_inner` becomes
+//!   `LocalTransport::dispatch`.
+//! - **CommandExecutor::dispatch** swaps its `if !is_local()`
+//!   error for a `match route(uri) { ... }` that uses the
+//!   transport selector.
+//!
+//! Each of those follow-ups is small because the typed primitive
+//! is in place. That's the point of starting here.

+//! Substrate-wide tracing-subscriber boot composition.
+//!
+//! Every continuum binary (server, demos, tests-that-care-about-probes)
+//! installs the SAME stack of tracing layers in the SAME order, via
+//! [`install_probe_tracing`]. Doing it once-per-binary stops the
+//! probe-availability accidentally diverging between
+//! `continuum-core-server` and the binaries / tests an operator wants
+//! to debug. Per Joel 2026-06-06: "Let's perfect debugging as we use
+//! it" — a single composition function is the substrate-purist way to
+//! keep the JTAG actually on across every entry point.
+//!
+//! ## What gets installed
+//!
+//! In order — each layer's docs explain what it does:
+//!
+//! 1. [`UriCaptureLayer`] — captures the URI ancestry chain at probe
+//!    fire time so [`stack!`] returns a meaningful path. Required by
+//!    both the broadcast router and the file sink.
+//! 2. [`ProbeRouterLayer`] — fans every `probe!` event to per-class
+//!    broadcast subscribers. The substrate's `debug/probes/*` URI
+//!    consumers read from this.
+//! 3. [`JsonlProbeFileSink`] — append-only JSONL log on disk, gated
+//!    by `CONTINUUM_PROBE_DIR` env var. Optional — if the env var
+//!    is unset the sink is silently skipped (the operator
+//!    intentionally didn't ask). Path-open failures are LOUD per
+//!    `[[no-fallbacks-ever]]` — caller decides whether to surface or
+//!    swallow the error.
+//! 4. A `fmt` layer reading [`tracing_subscriber::EnvFilter`] from
+//!    `RUST_LOG` (with a sensible default so the server still
+//!    prints info-level lines when nobody set `RUST_LOG`). Writes
+//!    to stderr so stdout stays clean for any caller piping the
+//!    server's output.
+//!
+//! ## Why this lives in `routing`
+//!
+//! Probe routing IS the substrate's per-class fanout primitive. The
+//! tracing-subscriber install is the operational shape that makes
+//! the in-tree macros (`probe!`, `time_sync!`, `stack!`) actually
+//! reach a consumer. Same module as `probe_router` + `probe_file_sink`
+//! + `macros` keeps "the JTAG end-to-end" in one place — anyone
+//! grepping for `JsonlProbeFileSink` lands next to the install
+//! function.
+//!
+//! ## Idempotency
+//!
+//! `try_init()` succeeds the first time and silently no-ops every
+//! subsequent call. Safe to call from a `#[tokio::main]` server
+//! binary AND from a test harness without coordinating across
+//! crates. Tests that want a NEW subscriber (clean capture) can
+//! use `tracing::subscriber::with_default(subscriber, || ...)`
+//! instead — that path doesn't touch the global default.

+//! `Transport` — the substrate's cross-grid dispatch seam.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` §"Transport
+//! selector": every non-Local [`RouteDecision`] is handed to a
+//! `Transport` impl. The dispatcher's match shape stays clean —
+//! Local stays inline (it operates on this substrate's owned
+//! modules + interceptors), and every Peer / Room / Broadcast
+//! variant routes through the same trait method.
+//!
+//! ## What this commit lands
+//!
+//! - The `Transport` trait
+//! - [`NotImplementedRemoteTransport`] — the substrate's default,
+//!   producing typed errors per variant that name the specific
+//!   missing transport
+//! - [`ClosureTransport`] — fixture-grade impl that delegates to a
+//!   closure, used by tests
+//!
+//! ## What the next commit lands
+//!
+//! - **AircTransport** — real cross-grid dispatch. Peer / Room /
+//!   Broadcast envelopes constructed, signed with the local
+//!   substrate's airc identity, sent through the existing
+//!   [`AircCitizen`](crate::persona::AircCitizen) primitive, awaited
+//!   and unpacked.
+//!
+//! ## Why only the remote side has a trait
+//!
+//! The Local arm operates on this substrate's owned state —
+//! `ModuleRegistry`, `Vec<CommandInterceptor>`, the TS bridge
+//! socket. Extracting it behind a trait would require either
+//! circular references back to `CommandExecutor` or rebuilding
+//! the transport every time an interceptor is added. The
+//! refactoring earnings are tiny and the surface gets messier.
+//!
+//! By contrast, the cross-grid transport is independent of those
+//! local concerns — its dispatch is a self-contained
+//! envelope-and-await against airc. A trait there cleanly
+//! abstracts "this peer's state isn't local; ask airc to deliver
+//! the call to wherever the peer lives."
+//!
+//! When the substrate gains a second non-Local concern (a grid
+//! capability transport, an HTTP bridge to legacy systems, etc.),
+//! either chain them like the interceptors or — more likely —
+//! introduce a transport selector that dispatches by
+//! [`RouteKind`](super::RouteKind). For now: one trait, one slot.
+//!
+//! ## Caller identity
+//!
+//! Today's trait method doesn't take a [`CallerIdentity`]. The
+//! local arm doesn't need one (this substrate's own code is
+//! implicitly trusted by the default policy); the remote arm
+//! doesn't carry one outbound (the substrate IS the caller from
+//! the remote peer's perspective). When the
+//! [`AircTransport`] commit lands, it adds caller propagation
+//! ON THE INBOUND side — extracting the verified sender from
+//! the airc envelope and threading it into the gate.

+//! URI-aware tracing Layer — Slice P keystone.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md`: every
+//! dispatched command establishes a `tracing::info_span!("cmd", uri =
+//! %command, ...)` and the substrate's tracing Layer captures the
+//! recorded `uri` field into a per-thread ancestry stack. The
+//! [`stack!`](crate::stack) macro reads that stack and returns the
+//! URI frames from outermost dispatch to current scope.
+//!
+//! ## What this Layer is responsible for
+//!
+//! - **Capture**: on every new span, if the span's attributes carry a
+//!   `uri = ...` field, extract the value and stash a [`UriFrame`] in
+//!   the span's extension storage.
+//! - **Push/pop**: on span enter/exit, push or pop the URI onto the
+//!   thread-local [`URI_STACK`]. `stack!()` simply clones it.
+//!
+//! ## What this Layer is NOT (yet) responsible for
+//!
+//! - Probe class routing — `probe!(class = "foo", ...)` events are
+//!   emitted as `tracing::event!`s with a `probe_class` field. A
+//!   separate Layer (follow-up commit) will route those to per-class
+//!   stream consumers reachable at
+//!   `airc://<actor>/debug/probes/<class>/stream`.
+//! - Timing rollup — `time!("scope", expr)` already creates a span; a
+//!   future Layer will aggregate durations into the
+//!   `/debug/profile/flamegraph` URI.
+//!
+//! ## Async + `Span::enter()` held across awaits
+//!
+//! `tracing` explicitly warns against holding a `_enter` guard across
+//! `.await` in async code — the thread-local entry/exit semantics
+//! break when tokio moves the task to a different thread mid-await.
+//! The substrate's correct pattern is `future.instrument(span).await`
+//! which trips `on_enter`/`on_exit` at task suspension boundaries.
+//!
+//! When code violates that pattern (currently
+//! [`CommandExecutor::dispatch`] does), this Layer's URI stack on a
+//! given thread may briefly contain entries for spans that have moved
+//! to other threads. That's a substrate bug to fix, not a Layer bug to
+//! work around. The follow-up commit converts dispatch to use
+//! `Instrument` so the stack stays correct across awaits.
+//!
+//! ## Re-entrancy and isolation
+//!
+//! [`URI_STACK`] is a `thread_local!` — each thread has its own. Tests
+//! that install the Layer once and run multiple span scopes
+//! sequentially observe a clean push/pop pattern. Parallel tests with
+//! distinct subscribers can't see each other's stacks.

+//! `Verdict` — the typed result of the substrate's auth gate.
+//!
+//! Per `docs/architecture/GRID-ADDRESSING-AND-ROUTING.md` (Slice P, RBAC
+//! section): every external command crossing the substrate boundary
+//! passes through ONE chokepoint where the typed gate evaluates
+//! `policy(caller_peer_id, uri) -> Verdict`. There is no parallel
+//! per-endpoint guard surface to drift; new commands inherit coverage
+//! the moment their URIs are registered.
+//!
+//! ## Variants
+//!
+//! - [`Verdict::Allowed`] — caller may execute; dispatcher proceeds
+//!   immediately
+//! - [`Verdict::Forbidden`] — typed refusal with [`ForbiddenReason`]
+//!   carrying the actionable cause (unknown peer, no permission for
+//!   URI, admission denied, revoked). Never silent permission grant
+//!   per [[no-fallbacks-ever]]; the substrate refuses loudly with the
+//!   reason
+//! - [`Verdict::Deferred`] — mediation required (e.g. "ask Maya's
+//!   primary env before evicting her LoRA"). Carries the prompt target
+//!   env. The dispatcher routes a consent prompt; the original URI
+//!   proceeds when consent is granted
+//!
+//! ## Why typed, not boolean
+//!
+//! A boolean `allowed: bool` gate loses the WHY. The operator
+//! debugging a denied request can't tell whether the caller's peer
+//! is unknown, the URI is unmatched, the rate limit is exceeded, or
+//! the target peer asked the gate to defer to consent. Typed
+//! variants surface the reason at the gate; the audit log captures
+//! it; the user-facing error message is actionable. Same compression
+//! principle the rest of the substrate uses: one typed result, all
+//! consumers exhaustively match.

+//! AircInterceptor — routes commands targeting airc-addressed peers via
+//! the airc messaging substrate. **Stub form: trait wired, transport
+//! deferred until the airc module ships its command-transport surface.**
+//!
+//! # Why this exists today, in stub form
+//!
+//! Per [docs/architecture/MODULE-ARCHITECTURE.md](../../../../../docs/architecture/MODULE-ARCHITECTURE.md)
+//! §7.1: airc is "just another module" providing a transport. The
+//! eventual contract is that `Commands::execute("foo/bar", { aircPeer:
+//! "id" })` should route the command over the airc messaging substrate
+//! to that peer's continuum-core, execute there, return the result.
+//! Same primitive as grid hops; different transport.
+//!
+//! Why land the interceptor in stub form before the transport exists:
+//!
+//! 1. The interceptor chain is a sequence; landing the airc slot now
+//!    pins the order before grid wires in. Today's wire order is
+//!    `[airc, grid]` — explicit airc-targeted commands take precedence
+//!    over grid's capability-based remote routing.
+//! 2. The stub fail-loud on actual airc targets (rather than silently
+//!    declining) keeps the contract honest: a caller who writes
+//!    `aircPeer: "..."` learns immediately that the transport isn't
+//!    ready, rather than having the request silently fall through to
+//!    local dispatch where there's no airc routing at all.
+//! 3. Per Joel's `[[every-error-is-an-opportunity-to-battle-harden]]`
+//!    standing rule: fail-loud surfaces the gap. Silent decline would
+//!    hide it under the rug until live chat traffic hits.
+//!
+//! # How callers signal an airc target
+//!
+//! `params.aircPeer: String` — explicit peer ID. The transport (when
+//! wired) routes to that peer's continuum-core over the airc substrate.
+//!
+//! `params.aircRoom: String` — broadcast to a room's members. Useful
+//! for "tell everyone in this conversation" semantics.
+//!
+//! Absent both, the interceptor declines and the chain continues.
+//!
+//! # When the transport lands
+//!
+//! Replace [`AircInterceptor::try_route`]'s `Err` path with a real call
+//! into the airc module's `airc/send-command` (or equivalent). The
+//! stub's structure already discriminates the param shape; only the
+//! transport call body needs to change.

+//! Artifact handle, selector, and cadence — pure data layer for PIECE-2
+//! of the CBAR substrate (artifact subscription, cadence, dependency
+//! declarations that `ServiceModule` will adopt in PR-2).
+//!
+//! Carries no runtime wiring. PR-2 adds these as Optional fields on
+//! `ModuleConfig` + a default `on_artifact_available` method on the
+//! trait. PR-3 wires the runtime to deliver artifact events on the
+//! configured cadence. This file ships the typed wire shape so PR-2
+//! has stable types to depend on + downstream consumers can start
+//! reasoning about subscriptions independently.
+//!
+//! ## What an artifact is
+//!
+//! An **artifact** is any named output a `ServiceModule` produces that
+//! other modules can subscribe to. Concrete examples from the codebase:
+//!
+//! - `cognition/rate_proposals.result` — produced when rate_proposals
+//!   IPC handler emits its scoring output. PR-2's persona module can
+//!   subscribe and react.
+//! - `paging/broker.snapshot` — produced each tick by PressureBroker.
+//!   Modules reading global pressure subscribe rather than poll.
+//! - `inference_capability/registry.update` — produced when
+//!   GridCapabilityAnnouncer.ingest_peer mutates the registry. Lane D's
+//!   `CognitionTurnFrame` can subscribe to know when remote inference
+//!   capacity changed.
+//!
+//! ## Why no hardcoded enum
+//!
+//! Per CLAUDE.md anti-pattern rules + Joel's "we do not hardcode"
+//! directive (vhsm-d1f4 audit pass 6): `ArtifactKind` is a `String`
+//! newtype, not a `pub enum`. Modules register their own artifact
+//! kinds at boot; the runtime doesn't carry a closed list. Adding a
+//! new module's artifact stream MUST NOT require a schema change.
+//!
+//! Same shape used by `inference_capability::InferenceKind` (codex's
+//! PR-1 of GRID-INFERENCE-ROUTING) — the convention is established and
+//! this file follows it.
+//!
+//! ## Failure-mode discipline
+//!
+//! - **No silent defaults**: every field carries explicit data; no
+//!   `Cadence::default()` that picks an arbitrary tick interval. The
+//!   broker / supervisor decides cadence per the dynamic-hardware-detect
+//!   rule.
+//! - **No fixed concurrency**: there's no `max_subscribers` field. A
+//!   subscription is a record, not a slot. Broker meters delivery
+//!   downstream.

+//! `BootMode` — explicit operator-intent flag for substrate boot.
+//!
+//! ## Why
+//!
+//! Slice A (PR #1527) used a heuristic: "if persona seeds exist on
+//! disk, assume the operator wants persona hosting; if not, assume
+//! they want inference-only." Reviewer R2 BLOCKed on
+//! [[no-fallbacks-ever]]: the operator NEVER stated they wanted
+//! inference-only mode; the substrate inferred it from a directory
+//! listing. That's silent substitution of a degraded capability set.
+//!
+//! A.2 replaces the heuristic with an explicit flag. The operator
+//! states intent via `--mode=<full-citizen|inference-only|fail-fast>`
+//! (default `full-citizen`). The substrate never guesses.
+//!
+//! ## The three modes
+//!
+//! - **FullCitizen** (default) — the substrate is expected to host
+//!   personas + run inference + everything else. AIRC must be
+//!   `Healthy` AND ≥1 persona seed must exist. Either missing →
+//!   refuse boot with the actionable repair message. This is the
+//!   common case for an operator running `continuum-core-server`
+//!   on their machine.
+//!
+//! - **InferenceOnly** — the operator explicitly wants the substrate
+//!   to come up WITHOUT persona hosting (e.g. a forge worker that
+//!   only runs `inference/`, `embedding/`, `forge/`, `cargo/`,
+//!   `code/`; a sandboxed CI runner; a model evaluation harness).
+//!   AIRC may be degraded; persona seeds may be absent. No
+//!   `PersonaInstanceManagerModule` is registered (or required).
+//!
+//! - **FailFast** — strictest mode. Refuses to boot if ANY
+//!   substrate capability is unavailable: AIRC unhealthy, ORT
+//!   missing, model files missing. Used by CI smoke tests and
+//!   production rollouts that want loud failure over silent
+//!   degradation.
+//!
+//! ## Threaded through `Context`
+//!
+//! Like `AircDiscovery`, `BootMode` is added to the `Context` trait
+//! (`fn boot_mode(&self) -> BootMode`) so every actor created
+//! during this boot carries the mode that was true at creation.
+//! Future B' code paths can dispatch on mode without re-reading
+//! argv.

+//! BrainRegion — the cognitive-cycle trait every brain region implements.

+//! Companion to ServiceModule. Where ServiceModule handles command/event
+//! routing (the existing dispatch surface), BrainRegion handles the
+//! cognitive tick: continuous parallel computation, yield telemetry,
+//! pressure registration, ready-buffer publishing.
+//!
+//! A real region (hippocampus, motor cortex, attention, sensory, sleep
+//! policy) implements BOTH ServiceModule (for cmd/event surface) and
+//! BrainRegion (for cognitive cycle). The runtime continues to dispatch
+//! via ServiceModule. The substrate governor (lands L0-4c) dispatches
+//! the cognitive tick via BrainRegion.
+//!
+//! Doctrine (from docs/architecture/BRAIN-REGIONS-SUBSTRATE.md):
+//!
+//! > No region of cognition runs on the hot path. Each region is its
+//! > own RTOS task with its own tick. The handler dispatches and reads
+//! > pre-staged results. The handler never blocks on recall, embedding,
+//! > planning, or admission — those are continuously produced by their
+//! > owning regions, in parallel, governed by SubstrateGovernor.
+//!
+//! ## L0-3a.0 scope (this slice)
+//!
+//! Pure typed surface. No region implementations. No governor
+//! integration. No derive macro, no scaffold generator (those land
+//! when ≥3 regions exist to motivate the abstraction — per the
+//! outlier-validation strategy in CLAUDE.md).

+//! Later slices ship: L0-3a.1 HippocampusModule skeleton, L0-3a.2+
+//! per-algorithm bodies, L0-4a motor cortex, L0-4b attention, L0-4c

+//! Cell return shapes per [MODULE-ARCHITECTURE.md §5.1](../../../../../docs/architecture/MODULE-ARCHITECTURE.md).
+//!
+//! A command returns one of four cell shapes. Today's `CommandResult`
+//! enum is the in-process Rust embodiment of those four shapes:
+//!
+//! | Cell shape (architecture) | `CommandResult` variant | Status |
+//! |---|---|---|
+//! | `Value<T>` (immediate typed result) | `Json(Value)` + `Binary { metadata, data }` | Mainline; back-compat |
+//! | `Handle<T>` (typed ref to state owned by producer) | `Handle(HandleRef)` | **Lands in this PR** |
+//! | `Stream<T>` (async sequence of values) | `Stream(StreamPlaceholder)` | Reserved variant; returning it errors until the wire protocol lands |
+//! | `Lambda<P, T>` (callable returned by a command) | `Lambda(LambdaPlaceholder)` | Reserved variant; returning it errors until the lambda protocol lands |
+//!
+//! The Json + Binary variants ARE the Value cell shape under the
+//! taxonomy; they're kept under their original names so the 300+
+//! existing command handlers don't need to change. New code that
+//! produces a plain typed result should still use `CommandResult::Json`
+//! (or `CommandResult::json(&value)?`). The Value name in the
+//! architecture doc is the categorical name; the implementation name
+//! stays Json for back-compat.
+//!
+//! # Why Handle is the headline shape
+//!
+//! Handle is the cell answer to MODULE-ARCHITECTURE.md §13.1 (hot-path
+//! cross-module state). A module produces a handle to its internal
+//! state; downstream commands take the handle as a param; the kernel
+//! routes those calls back to the producing module (whose handler
+//! looks up the state under the handle's `id`). No state copy, no
+//! lock contention across modules, same primitive locally as
+//! cross-machine. The producer owns; consumers compose by reference.
+//!
+//! The kernel does NOT need a global handle registry — each producing
+//! module manages the lifetime of its own handles internally (typed
+//! state map under the handle's `id`). The kernel sees a Handle the
+//! same as any other JSON payload; routing happens through the normal
+//! `Commands.execute(target/op, { handle })` path. The Handle struct
+//! is purely a data shape that travels through the existing primitive.
+//!
+//! # The canonical use cases (per Joel 2026-05-30)
+//!
+//! Handles are for **long-running stateful work** where the first call
+//! produces a handle and subsequent calls operate on it:
+//!
+//! - **inference** — `ai/inference/start { model, prompt }` returns a
+//!   handle; later `ai/inference/poll { handle }` and
+//!   `ai/inference/cancel { handle }` operate on the running session.
+//! - **training** — `training/run/start { recipe }` returns a handle;
+//!   `training/run/progress { handle }`, `training/run/cancel { handle }`
+//!   query and control the run.
+//! - **hosting** — `live/room/join { roomId }` returns a handle;
+//!   `live/audio/publish { handle, frame }` operates on the joined
+//!   session.
+//! - **ORM** — `data/transaction/begin` returns a handle;
+//!   `data/transaction/exec { handle, query }` and
+//!   `data/transaction/commit { handle }` thread the same transaction.
+//!
+//! All IDs are UUIDs. The producer mints a UUID, stores its state under
+//! that UUID, returns the handle. Subsequent calls carry the UUID; the
+//! producer's handler does an O(1) map lookup. The pattern works the
+//! same whether the producer runs in-process, in a sibling module, or
+//! on a remote peer over grid/airc.
+
+use serde::{Deserialize, Serialize};
+use ts_rs::TS;
+use uuid::Uuid;
+
+/// Typed reference to state owned by a specific module.
+///
+/// # Round-trip
+///
+/// 1. Producer command (e.g., `chat/send`) creates internal state
+///    (a message buffer, a session, a render context). It allocates a
+///    handle ID, stores the state under that ID in its own state map,
+///    and returns `CommandResult::Handle(HandleRef { owner: "chat",
+///    id, type_tag: "chat::MessageHandle", created_at_ms })`.
+///
+/// 2. Caller (Rust, TS, or remote) holds the HandleRef opaquely. It
+///    serializes through any wire crossing (it's plain JSON via serde).
+///
+/// 3. Caller invokes a downstream command that takes the handle:
+///    `Commands.execute("chat/message/get", { handle })`. The kernel
+///    routes to the chat module (`chat/` prefix in the registry); the
+///    chat module reads the handle's `id` from params and looks up its
+///    state map.
+///
+/// 4. Cross-module: if a different module needs to operate on the
+///    handle's underlying state, it asks the owner via a command:
+///    `Commands.execute("chat/message/get", { handle })` — same call,
+///    routed to the owner. The kernel doesn't care which module asked.
+///
+/// # `type_tag` discipline
+///
+/// Convention: `"<module>::<TypeName>"` matching the Rust type that
+/// produced the handle. e.g., `"chat::MessageHandle"`, `"rag::Slice"`,
+/// `"persona::InboxFrame"`. Lets typed callers cast safely on receipt
+/// without round-tripping through the producer.
+///
+/// # Lifetime
+///
+/// Producer owns the lifetime. The handle is valid as long as the
+/// producer's state map holds the ID. Producers may evict handles
+/// after a TTL, on session end, on resource pressure, etc. A consumer
+/// holding a stale handle gets a typed error from the producer's
+/// command handler (`"handle not found"`); the kernel doesn't
+/// participate in lifetime management. This is intentional — the
+/// kernel stays minimal, and lifetime policy belongs to the producer.
+///
+/// # Cross-machine
+///
+/// Same primitive. A handle minted on machine A is meaningful only on
+/// machine A. If a consumer on machine B calls a command taking that
+/// handle, the kernel's grid interceptor routes the call back to A
+/// (the handle's `owner` lives there). The handle ID never leaves A's
+/// state map; the remote call carries the ID, A executes the op
+/// locally, returns the result.

+//! Command envelopes — typed wrappers around the cross-cutting params
+//! and result fields every command shares.
+//!
+//! # The pattern
+//!
+//! Per Joel 2026-05-30: *"Some things are used so much should just be
+//! part of command result and params, handle for example. Find the
+//! patterns and simplify. The better the pattern, the easier to use
+//! the command or to reduce code size."*
+//!
+//! Right. A handle for long-running work, a session ID, a user ID,
+//! a success flag, an optional error message — these are cross-cutting
+//! concerns every command touches in some combination. Today's
+//! `ServiceModule::handle_command(command, params: Value) ->
+//! Result<CommandResult, String>` shovels everything through raw JSON;
+//! handlers re-parse the cross-cutting bits themselves and rebuild the
+//! same envelope at every return point.
+//!
+//! This module gives that pattern a name:
+//!
+//! - **`CommandRequest<P>`** — typed envelope around an inbound command:
+//!   the command-specific params `P` flattened with `handle`, `sessionId`,
+//!   `userId`. Parsers + accessors live here so handlers don't re-roll
+//!   the wheel.
+//!
+//! - **`CommandResponse<T>`** — typed envelope around the outbound
+//!   result: the command-specific data `T` flattened with `success`,
+//!   `error`, optional `handle` for follow-up calls. Builder-style API
+//!   so producing both data AND a handle is one fluent expression.
+//!
+//! Existing handlers keep their `Value`-based signatures (back-compat
+//! for the 300+ surface). New handlers opt into the typed shape via
+//! `CommandRequest::<P>::from_value(params)?` at the entry +
+//! `.into_command_result()?` at the exit. Same `ServiceModule` trait,
+//! tighter internal pattern.
+//!
+//! # What this collapses
+//!
+//! Before:
+//!
+//! ```ignore
+//! async fn handle_inference_start(
+//!     &self,
+//!     params: Value,
+//! ) -> Result<CommandResult, String> {
+//!     let p: InferenceStartParams =
+//!         serde_json::from_value(params.clone()).map_err(|e| e.to_string())?;
+//!     let session_id = params
+//!         .get("sessionId")
+//!         .and_then(|v| v.as_str())
+//!         .and_then(|s| Uuid::parse_str(s).ok());
+//!     let id = Uuid::new_v4();
+//!     self.sessions.insert(id, InferenceSession::new(p));
+//!     Ok(CommandResult::Json(serde_json::json!({
+//!         "success": true,
+//!         "firstToken": first_token,
+//!         "handle": HandleRef::with_id("ai/inference", id, "ai::InferenceSession"),
+//!     })))
+//! }
+//! ```
+//!
+//! After:
+//!
+//! ```ignore
+//! async fn handle_inference_start(
+//!     &self,
+//!     params: Value,
+//! ) -> Result<CommandResult, String> {
+//!     let req = CommandRequest::<InferenceStartParams>::from_value(params)?;
+//!     let id = Uuid::new_v4();
+//!     self.sessions.insert(id, InferenceSession::new(req.params));
+//!     CommandResponse::ok(InferenceStartData { first_token })
+//!         .with_handle("ai/inference", id, "ai::InferenceSession")
+//!         .into_command_result()
+//! }
+//! ```
+//!
+//! The cross-cutting fields stop being something handlers have to know
+//! about. They become free.

+//! Priority 3: the substrate must emit completion events on the bus
+//! so the autonomous persona loop can stay reactive. Polling violates
+//! the RTOS-brain doctrine ("handlers read pre-staged results, never
+//! block on recall/embedding/planning") — a persona that has to
+//! `code/shell/watch` in a poll loop freezes its inbox cadence.
+//!
+//! # The event
+//!
+//! Every command dispatched through [`CommandExecutor::execute`]
+//! emits ONE [`CommandCompletedEvent`] on the bus, regardless of
+//! whether the command succeeded, errored, or routed through an
+//! interceptor. The event's `success` field distinguishes — a single
+//! topic + a boolean is simpler than two parallel topics and lets
+//! subscribers filter by predicate.
+//!
+//! # Topic
+//!
+//! Published on `command:completed`. Follows the bus's
+//! `<namespace>:<action>` convention (matching `data:<collection>:<action>`
+//! and `chat:<verb>` patterns elsewhere). Subscribers register via
+//! `bus.subscribe("command:completed", ...)` or via a glob like
+//! `command:*` for forward-compat with future events
+//! (e.g. `command:queued`, `command:dispatching`).
+//!
+//! # Compositional value (per the alignment-via-substrate-economics memory)
+//!
+//! Once every dispatch emits a structured completion event, attribution
+//! becomes substrate-observable in real time. A persona on machine A
+//! authoring a module + running `cargo/test` against it emits a
+//! `command:completed` event that peers on B/C/etc. subscribed to the
+//! room see — turning "I built this" into "the grid knows I built this"

+//! CommandExecutor — Universal command execution for ALL continuum-core processes
+//!
+//! This is the foundational primitive that allows ANY spawned task (sentinels,
+//! background jobs, etc.) to execute ANY command in the system, regardless of
+//! whether it's implemented in Rust or TypeScript.
+//!
+//! Usage:
+//! ```rust
+//! // Works for Rust modules
+//! runtime::execute_command_json("health-check", json!({})).await?;
+//!
+//! // Works for TypeScript commands (via CommandRouterServer)
+//! runtime::execute_command_json("screenshot", json!({"querySelector": "body"})).await?;
+//!
+//! // Sentinel doesn't know or care where command is implemented
+//! ```
+//!
+//! Architecture:
+//! - Rust modules: Routed directly through ModuleRegistry
+//! - TypeScript commands: Routed via Unix socket to CommandRouterServer
+//!   (socket: /tmp/jtag-command-router.sock)

+/// # Dispatch order (the chain)
+///
+/// Per [docs/architecture/MODULE-ARCHITECTURE.md](../../../../../docs/architecture/MODULE-ARCHITECTURE.md)
+/// §5 ("Composition: Commands Call Commands"): every command walks the
+/// same dispatch chain regardless of which language or machine
+/// implements it. The chain is:
+///
+/// 1. **Interceptors** (in insertion order). Each one gets first look at
+///    `(command, params)`. An interceptor can take the command (and
+///    short-circuit the chain), pass (`Decline` — try the next), or
+///    fail (`Err` — propagate immediately, no silent fallthrough).
+///    Today's intended order is `[airc, grid]`: explicit airc-routed
+///    commands beat grid's capability-based remote routing.
+///
+/// 2. **Local Rust module registry**. If no interceptor took the
+///    command, the registry tries to find a Rust `ServiceModule` whose
+///    `command_prefixes` include this command. If found, the module's
+///    `handle_command` runs locally.
+///
+/// 3. **TypeScript via Unix socket**. If no Rust module owns the
+///    command, fall through to the existing `CommandRouterServer` IPC
+///    bridge. This preserves backwards compatibility with every
+///    TS-implemented command in `src/commands/`.
+///
+/// The chain is the same primitive for every transport: local Rust,
+/// remote Rust over grid, remote Rust over airc, TS over IPC. Adding a
+/// transport is adding an interceptor; no kernel changes needed.

+//! CommandInterceptor — the routing-decision chain that runs before local
+//! dispatch in [`super::command_executor::CommandExecutor`].
+//!
+//! # Why this exists
+//!
+//! Per [docs/architecture/MODULE-ARCHITECTURE.md](../../../../../docs/architecture/MODULE-ARCHITECTURE.md)
+//! §5 ("Composition: Commands Call Commands") and §7.1 ("airc as just
+//! another module"): the kernel composes routing decisions by walking a
+//! chain of interceptors before falling back to local Rust dispatch and
+//! finally to TypeScript. No transport is special at the kernel level —
+//! grid, airc, future mesh transports, future caching layers all sit
+//! behind the same trait and the same dispatch loop.
+//!
+//! Today's `CommandExecutor::execute` already does the local-Rust-then-TS
+//! pair. This trait adds the prefix: interceptors get FIRST look. The
+//! result is a single primitive that handles four transport modes
+//! (local Rust, IPC to TS, grid hop to a peer, airc routing to a peer)
+//! with one entry point and one signature.
+//!
+//! # The contract
+//!
+//! Implementations decide per call whether to handle the command or step
+//! aside:
+//!
+//! - [`InterceptorOutcome::Handled`] — interceptor took the command;
+//!   the chain stops and this result is returned to the caller.
+//! - [`InterceptorOutcome::Decline`] — interceptor passed; the next
+//!   interceptor (or the local-dispatch fallthrough) takes over.
+//! - `Err(_)` — interceptor failed in a way the caller should see;
+//!   the chain stops and the error propagates. No silent fallthrough
+//!   on Err — that would hide exactly the routing bugs interceptors

+//!
+//! # Composition order
+//!
+//! Interceptors are walked in insertion order. Wire order is therefore
+//! policy: the earlier an interceptor sits, the higher its priority.
+//! Today the intended order is `[airc, grid]` so explicit airc-targeted
+//! commands take precedence over grid's capability-based remote routing.
+//! Both currently decline by default (airc has no transport yet; grid is
+//! not yet wired here) so adding the chain is a no-op until those land.
+//!
+//! # Why not just modify `CommandExecutor::execute` per-transport
+//!
+//! The legacy TS-side dispatch [pre-#1198] grew a `_gridInterceptor`
+//! shim on the singleton specifically to hop work over to the grid before
+//! local dispatch. That worked but baked grid into the kernel signature.
+//! The same pressure exists for airc, and any future transport (mesh,
+//! tower-relay, etc.) would re-bake the kernel each time. The interceptor
+//! trait is the generalization: kernel knows "walk a list, fall through
+//! when no one bites"; transports register themselves.

+//! GridInterceptor — bridges the existing [`crate::modules::grid`] routing
+//! into the kernel's [`super::command_interceptor::CommandInterceptor`]
+//! chain.
+//!
+//! # What this connects
+//!
+//! The grid module already owns the routing policy + the send-frame
+//! dispatch:
+//!
+//! - `crate::modules::grid::router::GridRouter::route(command, params, registry)`
+//!   returns `Local` or `Remote { node }` based on explicit `nodeId`
+//!   params, `routingHint` hints, and capability matching.
+//! - `crate::modules::grid::handlers::dispatch_to_node(state, node, cmd, params)`
+//!   opens a transport connection, sends a CommandRequest frame, awaits
+//!   the matching CommandResult frame, audits the round-trip, returns
+//!   the deserialized result.
+//!
+//! Pre this interceptor, the only callers were:
+//!
+//! - `grid/send` (explicit) — the user (or a Rust caller) names the
+//!   target node and command, dispatches over the grid wire.
+//!
+//! Post this interceptor, capability-based routing works for ANY
+//! command: a caller writing `ai/generate { routingHint: "max-compute"
+//! }` triggers the router → picks a remote node with the most VRAM →
+//! dispatches the command there → returns the remote result. All
+//! through the same kernel `Commands.execute` primitive; the routing
+//! decision is invisible to the caller.
+//!
+//! # Position in the chain
+//!
+//! Wire order (`init_executor`): `[airc, grid]`. Explicit airc-targeted
+//! commands take precedence over grid's capability-based routing so a
+//! caller who writes `aircPeer: "..."` doesn't get accidentally hopped
+//! over grid's max-compute heuristic.
+//!
+//! # Why not in the grid module
+//!
+//! GridInterceptor lives in `runtime/` (not `modules/grid/`) because the
+//! interceptor TRAIT is a runtime concept — every transport interceptor
+//! sits behind it, and the runtime is what walks the chain. The
+//! interceptor's *implementation* delegates to grid; that's just a
+//! dependency the runtime takes on the grid module, mediated by the
+//! `Arc<GridState>` public handle.

+//! Modular Runtime Framework
+//!
+//! RTOS-inspired module system for the Continuum Core process.
+//! Every service module implements ONE trait (ServiceModule), registers with
+//! the runtime, and commands route automatically. Like CBAR's appendAnalyzer().
+//!
+//! Components:
+//! - ServiceModule: The ONE trait every module implements
+//! - ModuleRegistry: DashMap-based command routing (replaces 55-arm match)
+//! - MessageBus: Inter-module pub/sub with glob patterns
+//! - SharedCompute: Lazy-compute-once cache (like CBAR_VideoFrame)
+//! - ModuleContext: Module's view of the runtime
+//! - ModuleLogger: Per-module segregated logging
+//! - ModuleMetrics: Built-in IPC performance monitoring
+//! - RuntimeControl: Priority adjustment API for UI
+//! - Runtime: Lifecycle orchestration
+//!
+//! Global Logging:
+//! - Any code can call `runtime::logger("component")` to get a logger
+//! - Logs go to `.continuum/jtag/logs/system/modules/{component}.log`
+//! - No need to pass loggers through function parameters

+//! ReadyBuffer — the publish/peek surface that every brain region
+//! uses to hand off pre-staged results to handlers without blocking.
+//!
+//! Doctrine (from docs/architecture/BRAIN-REGIONS-SUBSTRATE.md):
+//!
+//! > Empty buffer is a signal, not a block. If a handler reads and
+//! > gets None, it proceeds with whatever degraded path the algorithm
+//! > specifies. Slightly-stale context > stalled persona.
+//!
+//! ## Semantic rules
+//!
+//! - **Reads MUST NOT block** — handlers call `peek` on the hot path;
+//!   it MUST complete in microseconds and MUST NOT `await`. The
+//!   [`DashMapReadyBuffer`] default impl honors this via DashMap's
+//!   sharded locks.
+//! - **Staleness is acceptable** — a ready value might be 100ms old;
+//!   that's better than blocking the handler 500ms to recompute.
+//! - **Per-region buffers, not a global one** — hippocampus owns its
+//!   engram-prefetch buffer; motor cortex owns its candidate-utterance
+//!   buffer. They share the same trait shape but live in their own
+//!   region structs.
+//! - **TTL eviction** is region-owned — regions decide what "stale"
+//!   means for their value type.
+//!
+//! ## L0-3a.0 scope (this slice)
+//!
+//! Trait definition + a single default `DashMap`-backed implementation.
+//! No region-specific buffers yet (those land with their owning regions
+//! in L0-3a.1+, L0-4a, L0-4b, etc.).

+///   reference to state owned by the producing module. See
+///   [`super::cell_shapes::HandleRef`] for the round-trip protocol.
+///   Answers MODULE-ARCHITECTURE.md §13.1 (hot-path cross-module

+///   so the enum shape is fixed before the wire protocols land. See

+//! DiskPressureMonitor — Independent, non-blocking disk-pressure surveillance.
+//!
+//! Mirror of [`MemoryPressureMonitor`](super::memory_pressure::MemoryPressureMonitor)
+//! for disk. Own tokio task, own interval, watch channel for snapshot
+//! publication, atomic gate for lock-free hot-path checks, per-source
+//! reporters via spawn_blocking + 100 ms timeout, quarantine after 3
+//! consecutive failures. Crash-isolated: panics anywhere inside the
+//! loop or in a reporter are caught and counted, never propagated.
+//!
+//! Same shape because the substrate's RTOS doctrine is one shape per
+//! concurrent concern — see
+//! [`docs/architecture/CONCURRENCY-STYLE-GUIDE.md`](../../../../../docs/architecture/CONCURRENCY-STYLE-GUIDE.md).
+//!
+//! ## Why disk pressure as a substrate concern
+//!
+//! Joel 2026-06-08: the substrate eats disk. Cargo target dirs, model
+//! caches, fixture archives, probe JSONL spool, persona home stores,
+//! airc worktrees. None of these are individually unbounded; together,
+//! on an Intel MacBook Pro with no swap room, they crash the machine.
+//! The disk-guard slop that triggered the CONCURRENCY-STYLE-GUIDE was
+//! a synchronous, env-tuned, main-thread `runtime/disk_guard.rs`. This
+//! is the right shape: own task, watch channel, broker-arbitrated.

+//!
+//! ## Cadence
+//!
+//! 30 s — disk fills slowly. The CONCURRENCY-STYLE-GUIDE's cadence
+//! ladder says "lean slower when in doubt; the cost of a missed-by-a-
+//! second spike is one eviction cycle." Memory polls every 2 s
+//! because RSS can spike in milliseconds; disk doesn't.
+//!
+//! ## Future
+//!
+//! - Register as a `ResourcePool` with the `PressureBroker` so disk
+//!   pressure participates in cross-resource tier-relief (task #88).
+//! - Implement `ServiceModule` so the Runtime owns the lifecycle and
+//!   `ready_edge()` works through the canonical seam (slice A.5).
+//! - Sweep policy under pressure (Critical → delete oldest cargo
+//!   incremental, oldest probe JSONL files, etc.).

+//! UTF-8-safe string truncation helpers.
+//!
+//! `&str` indexing in Rust slices by BYTE offsets — `s[..N]` panics with
+//! "byte index N is not a char boundary" when N lands inside a multi-byte
+//! UTF-8 sequence. The idiom `&s[..s.len().min(N)]` is therefore unsafe
+//! for any text that might contain non-ASCII characters (emoji, accented
+//! letters, CJK, etc.) — and chat content / decoded LLM tokens routinely
+//! contain those.
+//!
+//! Concretely: this codebase had 8 sites doing `&s[..s.len().min(N)]` for
+//! diagnostic / debug logging across persona cognition, inference backends,
+//! and grid handlers. Each one was a latent panic that fired when a chat
+//! message or decoded token happened to have a multi-byte char near the
+//! truncation boundary. Production today tends to miss these because
+//! tracing's compile-time level filter strips most `debug!` invocations,
+//! but as soon as someone runs RUST_LOG=debug on real chat traffic the
+//! crash surface opens.
+//!
+//! This module centralizes the safe-truncate primitive so every consumer
+//! gets the same behavior and the lesson lands once rather than 8 times.
+//! Per Joel 2026-05-30 "every error is an opportunity to battle harden" —
+//! the fix isn't just the call sites, it's making the safe primitive the
+//! easy thing to reach for.
+
+/// Return the longest prefix of `s` whose byte length is at most
+/// `max_bytes`, rounding DOWN to the nearest char boundary. Never
+/// panics on UTF-8 multi-byte sequences.
+///
+/// `&s[..s.len().min(N)]` is the panic-prone idiom this replaces:
+/// when byte index N lands inside a multi-byte UTF-8 sequence the
+/// slice panics with "byte index N is not a char boundary." Real-world
+/// trigger: a chat message with an emoji at byte 28-31 hits a 30-byte
+/// truncation and crashes the persona cognition path.
+///
+/// Cost: O(min(4, max_bytes - actual_boundary)) — at most 3 backtracks
+/// because UTF-8 chars are bounded to 4 bytes. Effectively free for the
+/// log-truncate use case.
+///
+/// # Examples

+//! This is the read side of the artifact-writer (`artifacts.rs`) that the

+//! Mac, the latest fail on Windows, the regressions since last release"
+//! etc). The reader is the data-access primitive every reporting consumer
+//! shares — the `vdd/report` IPC command is one of them; the precommit

+//! Live persona-turn replay fixture — bundles the input + output
+//! of a single prod persona turn into one machine-readable JSON
+//! record per Joel's "live record/replay proof" ask.
+//!
+//! Why this exists separately from `persona::recorder` and the
+//! VDD `StandardVddRecord`:
+//!
+//! - `persona::recorder` writes per-turn cognition fixtures under
+//!   `~/.continuum/fixtures/persona-respond/` — input + output +
+//!   cognition trace. Keyed by persona + message id + ts. Optimized
+//!   for replay determinism (rerun the same cognition turn against
+//!   a new build).
+//!
+//! - `vdd::artifacts::ArtifactWriter` writes harness scenario
+//!   records under `~/.continuum/vdd/<git_sha>/<scenario>/record.jsonl`
+//!   — pass/fail summary, hardware/backend, latency metrics. Keyed
+//!   by git_sha + scenario for cross-PR comparison. Optimized for
+//!   "did this commit regress vs the last one."
+//!
+//! - THIS module writes "live turn replay" fixtures under
+//!   `~/.continuum/vdd/<git_sha>/turn-replays/<turn_id>.json` —
+//!   bundles the substrate-side view of one persona turn (the
+//!   `PersonaTurnFrameReplayRecord` v2 input, the
+//!   `InferenceComplete` output, the `FirstTokenEmitted` event,
+//!   plus capture metadata). Keyed by git_sha + turn_id. Purpose:
+//!   PROOF that on this commit, on this hardware, a real persona
+//!   turn end-to-end produced this exact output for this exact
+//!   input. Not aggregated — the unit IS the proof.
+//!
+//! The hook into `persona/turn-execute` (Lane D #1409) that
+//! actually writes these fixtures lands in a follow-up PR — this
+//! PR ships the data substrate (schema + writer + reader + tests)
+//! so the hook PR is small and reviewable.

+//! Integration test: `continuum-client::AircIpcTransport` (client side)
+//! round-trips an `AircCommandRequest` against the substrate's actual
+//! `CommandRequestHandler::parse_envelope` + `send_reply` (server side)
+//! over the `TwoAircLoopback` fixture.
+//!
+//! ## What this catches
+//!
+//! Reviewer 3 on PR #1558 round 1 flagged that the earlier integration
+//! test inlined `serde_json::from_value` instead of calling the
+//! substrate's real parser. That meant drift between the client's
+//! envelope and `CommandRequestHandler::parse_envelope`'s expectations
+//! would NOT fail the test. This test fixes that by driving the
+//! SUBSTRATE'S OWN `pub` parse + reply functions from the responder.
+//!
+//! If at any point the substrate parser starts requiring a new header,
+//! drops a required header, changes the `kind` discriminator, or
+//! changes the response envelope shape, this test fails — the wire
+//! shape is now actually verified end-to-end against the real
+//! substrate code, not a parallel inline parser.

+//! Wire-contract regression test: the `ctm generate` CLI's inline-JSON
+//! params shape MUST round-trip through `TextGenerationRequest`'s
+//! serde decoder.
+//!
+//! ## Why this lives in continuum-core's tests
+//!
+//! The CLI (`apps/cli`) intentionally does NOT dev-depend on
+//! `continuum-core` types — it constructs JSON inline to match the
+//! wire shape (see `apps/cli/src/main.rs::run_generate`). That makes
+//! the wire shape a SILENT contract: drift in either direction
+//! (substrate adds a required field; CLI typos a field name) is
+//! invisible until the first live dispatch fails at the substrate.
+//!
+//! This test pins the CLI's exact JSON shape against the substrate's
+//! `TextGenerationRequest` decoder. If the CLI's shape ever stops
+//! decoding cleanly, this test fails at `cargo test -p continuum-core`
+//! — before any operator types `ctm generate --prompt ...` and hits
+//! a useless "data did not match any variant of untagged enum
+//! MessageContent" error from the substrate.
+//!
+//! ## What the contract is
+//!
+//! Per `core/continuum-core/src/ai/types.rs`:
+//! - `ChatMessage.content: MessageContent`
+//! - `MessageContent = #[serde(untagged)] enum { Text(String), Parts(Vec<ContentPart>) }`
+//! - An OBJECT shape (e.g. `{"type": "text", "text": "..."}`) matches
+//!   NEITHER variant — Text wants a string, Parts wants an array.
+//!
+//! The CLI uses the simplest shape — plain string. The substrate's
+//! own legacy `prompt`-param path produces the same shape, so it's
+//! the safest wire choice (already exercised end-to-end).
+//!
+//! Regression caught: PR #1561 round 1 R1 review (BLOCK, 98 conf).
+//! The original PR shipped `"content": {"type": "text", "text": ...}`
+//! (object). Every `ctm generate` invocation would have failed at
+//! the substrate. This test would have caught it pre-merge.
+
+use continuum_core::ai::types::{MessageContent, TextGenerationRequest};

+/// The EXACT JSON shape `ctm generate --prompt "hello"` builds.
+/// Hand-mirror what `apps/cli/src/main.rs::run_generate` constructs.

+//! Ratchet test: `protocol/typescript/<module>/index.ts` must stay in
+//! sync with the `.ts` files in that module directory.
+//!
+//! # Why this exists
+//!
+//! Every `#[derive(TS)]` type in `continuum-core` has a
+//! `#[ts(export, export_to = "../../../protocol/typescript/<module>/<Type>.ts")]`
+//! that materializes a TypeScript binding when `cargo test` runs the
+//! type's `export_bindings_*` test (which ts-rs auto-generates).
+//!
+//! The per-module `index.ts` barrel — generated by
+//! `generator/generate-rust-bindings.ts` — is what consuming TypeScript
+//! imports from. If a new `.ts` file lands without the barrel being
+//! regenerated, the type is invisible to TS consumers even though the
+//! file exists on disk. That's exactly what regressed on PR #1129
+//! (commit db271d310: "fix(persona): export generated engram bindings"
+//! manually added 12 export lines after the fact). This ratchet makes
+//! the same regression impossible by failing `cargo test` whenever any
+//! module's barrel drifts from its `.ts` files.
+//!
+//! # What this catches
+//!
+//! - A new `.ts` file exists in `protocol/typescript/<module>/` but has no
+//!   `export type { X } from './X'` line in `index.ts`.
+//! - A barrel exports a type whose `.ts` file no longer exists
+//!   (cleanup regression — the export would dangle).
+//!
+//! # What this does NOT catch
+//!
+//! - Drift between Rust source's `#[derive(TS)]` annotations and the
+//!   actual `.ts` file contents (ts-rs's own export tests cover that —
+//!   they fail at test time if the generated content doesn't match).
+//! - Manual `.ts` files in `protocol/typescript/` (none should exist —
+//!   the dir is auto-generated end-to-end).
+//!
+//! # Failure recovery
+//!
+//! When this fails: run `npx tsx generator/generate-rust-bindings.ts`
+//! from `src/`, commit the regenerated barrel(s), retry. The failure
+//! message names every offending module + the specific files that drift.

+//! Regression test for the no-CPU-fallback alpha contract (#1262 → #1275 → #1280).
+//!
+//! Continuum's documented contract per `project_continuum_alpha_product_bar_sensory_personas.md`
+//! and `docs/architecture/SENSORY-PERSONA-ALPHA-CONTRACT.md` is **NO silent CPU fallback**:
+//! standard personas use `SiliconResidencyRequirement::GpuOrUnifiedMemoryOnly` and the model
+//! resolver is supposed to refuse rather than fall through to CPU.
+//!
+//! Pre-#1280 this contract was enforced (in part) by an explicit `panic!` inside
+//! `inference::model::select_best_device`. That function lived in the dead Candle
+//! chain (CandleAdapter → ContinuumModel → select_best_device), unreachable from
+//! `AIProviderModule::register_adapters`. #1280 deleted the chain and moved the
+//! contract assertion to its actually-load-bearing site:
+//!
+//!   `LlamaCppConfig::default()` sets `n_gpu_layers: -1` (= "all layers on GPU").
+//!   When no GPU is available, llama.cpp's own model loader hard-fails — this is
+//!   the runtime mechanism that prevents CPU fallback on the production hot path.
+//!
+//! This test asserts the `n_gpu_layers: -1` invariant by source inspection plus the
+//! ort_providers + LlamaCppAdapter assertions that survived #1280 unchanged.
+//!
+//! Pattern: forbidden-strings ratchet (same shape as lane F PR-2 #1129 — TS persona
+//! forbidden-strings ratchet) applied to the Rust inference layer.
+//!

+//! `#[derive(Entity)]` — the Rust analogue of TS class decorators for
+//! continuum-core's ORM.
+//!
+//! ### What it does
+//!
+//! Walks the struct's fields, infers each field's `FieldType` from the
+//! Rust type, honors per-field `#[entity(...)]` attribute overrides,
+//! and emits `impl OrmEntity for #name` automatically. The hand-written
+//! 100-line `collection_schema()` block collapses to per-field
+//! attributes — and structural drift between the struct and the schema
+//! becomes impossible: the schema IS the struct.
+//!
+//! ### Doctrine
+//!
+//! Per [[orm-everything-not-hand-edited-files]] +
+//! [[no-sql-everything-through-orm-entities]] + Joel's 2026-06-03
+//! directive ("Entities need to be defined, and in one place, rust"):
+//! the Rust struct is the single source of truth for what an entity
+//! IS. Everything else — the ORM schema, the ts-rs TS type, future
+//! JSON Schema / OpenAPI / IPC payloads — is generated. Drift is a
+//! structural impossibility, not a discipline problem.
+//!
+//! ### Example
+//!
+//! ```ignore
+//! use continuum_orm_derive::Entity;
+//! use continuum_core::orm::BaseEntity;
+//! use serde::{Deserialize, Serialize};
+//! use uuid::Uuid;
+//!
+//! #[derive(Debug, Clone, Serialize, Deserialize, Entity)]
+//! #[entity(collection = "engrams")]
+//! pub struct Engram {
+//!     #[serde(flatten)]
+//!     pub base: BaseEntity,
+//!     #[entity(indexed)]
+//!     pub kind: String,
+//!     pub content: String,
+//!     #[entity(json)]
+//!     pub origin: serde_json::Value,
+//!     #[entity(indexed)]
+//!     pub admitted_at_ms: u64,
+//!     pub admission_trace_id: Option<String>,
+//! }
+//! ```
+//!
+//! ### Type inference rules
+//!
+//! | Rust type                       | FieldType          | Notes                       |
+//! |---------------------------------|--------------------|-----------------------------|
+//! | `String` / `&str`               | `String`           |                             |
+//! | `Uuid`                          | `Uuid`             | Detected by type-name match |
+//! | `bool`                          | `Boolean`          |                             |
+//! | `u*` / `i*` / `f32` / `f64`     | `Number`           |                             |
+//! | `Vec<T>` / `HashMap` / `BTreeMap` | `Json`           | JSON-serialized container   |
+//! | `Option<T>`                     | inner T's FieldType + nullable | unwrapped one level     |
+//! | Enum (variant-only)             | `String`           | Serializes as variant name  |
+//! | Any other named struct          | `Json`             | Nested struct → JSON column |
+//!
+//! Override with `#[entity(json)]` to force any field to a JSON column
+//! regardless of inferred type. The `BaseEntity` field marked
+//! `#[serde(flatten)]` is detected by type name and its columns are
+//! added via `base_entity_fields()` rather than appearing as a
+//! single JSON column.
+//!
+//! ### Field-level attributes
+//!
+//! - `#[entity(primary_key)]` — declares this field IS the BaseEntity
+//!   id (`id: Uuid`). Pulls in `base_entity_fields()` and skips
+//!   emitting this field separately so the schema doesn't get a
+//!   duplicate `id` column. Use for entities that carry the primary
+//!   key as a bare `Uuid` rather than embedding a `BaseEntity`
+//!   struct via `#[serde(flatten)]`. Mutually exclusive with the
+//!   embedded-BaseEntity form.
+//! - `#[entity(indexed)]` — single-field index
+//! - `#[entity(unique)]` — unique constraint
+//! - `#[entity(nullable)]` — explicit nullable (auto for `Option<T>`)
+//! - `#[entity(json)]` — force JSON column (override inferred type)
+//! - `#[entity(skip)]` — exclude from the schema (in-memory only)
+//! - `#[entity(foreign_key("engrams.id"))]` — declare a foreign-key
+//!   reference. Cascade rules default to `Restrict` on delete and
+//!   update; override with
+//!   `foreign_key("engrams.id", on_delete = "cascade", on_update = "restrict")`.
+//!   Cascade keywords: `"restrict" | "cascade" | "set_null" | "no_action"`.
+//!
+//! ### Struct-level attributes
+//!
+//! - `#[entity(collection = "name")]` — REQUIRED. The collection name.
+//! - `#[entity(index(name = "idx_x", fields = ["a", "b"]))]` — composite
+//!   index across multiple fields. Add `unique = true` for a unique
+//!   composite. Repeat the attribute for multiple indexes.

+/// Source of truth, in order:
+///
+/// 1. **`INFERENCE_WORKERS` environment variable** — the channel a
+///    supervising continuum-core sets at process spawn based on its
+///    PressureBroker lease. When set, that value is the policy and
+///    inference-grpc uses it verbatim. No floor, no ceiling — supervisor
+///    knows the live hardware + memory pressure better than this binary
+///    does. Invalid integer in the env var is a configuration bug:
+///    return Err with the bad value named (no silent default).
+///
+/// 2. **No env var set** — Continuum-core wasn't the spawner (direct
+///    `cargo run`, integration test, docker exec). Fall back to the
+///    physical CPU count from `num_cpus`. CPU count is hardware-derived,
+///    not hardcoded; one worker per physical core is the most
+///    conservative "make use of the box" default. Caller sees a single
+///    info log line announcing the fallback.
+///
+/// What this fn DOES NOT do anymore (deletion targets from CBAR-PIECE-8
+/// + vhsm-d1f4 audit pass 1):
+///
+/// - **No more `~/.continuum/config.env` parsing.** Static-config-file
+///   reads violate the dynamic / broker-owned-concurrency rule. If a
+///   user wants to override, they pass `INFERENCE_WORKERS` as an env
+///   var on the process line; no file-on-disk side channel.
+/// - **No more `clamp(1, 4)` / `clamp(1, 8)` ceilings.** Hardcoded
+///   ceilings prevent the supervisor from sizing the pool for a
+///   Blackwell with 128GB RAM (capped at 4 workers, same as a 16GB
+///   MacBook Air). Removed entirely — supervisor sets the ceiling, this
+///   binary doesn't.
+/// - **No more `2GB-per-worker` magic constant.** Per-worker footprint
+///   depends on the model + quantization + context window; a fixed
+///   number is wrong for every model that isn't a 7B Q4_K_M. Calculation
+///   was wrong; deleted.
+/// - **No more `Default: 2 workers` fallback** — silent default was
+///   the exact "guess and silently degrade" anti-pattern vhsm-d1f4
+///   called out. Fallback is now `num_cpus::get_physical()` (hardware-
+///   probed, never zero) with an info log so the operator can see what
+///   was picked.

+//! llama — our owned substrate for local LLM inference.
+//!
+//! Vendors llama.cpp as a git submodule, builds it via cmake, exposes a safe
+//! Rust API. One binary, no external process, cross-platform via features.
+//!
+//! Features:
+//!   - `metal`: Apple Silicon GPU (Mac) — REQUIRED on macOS
+//!   - `cuda`: NVIDIA GPU (Linux + Windows/WSL)
+//!   - default: CPU with BLAS
+
+// ── Compile-time guard: no silent CPU-only Mac builds ─────────────────
+// If you build this crate on macOS without `--features metal`, llama.cpp
+// is compiled with GGML_METAL=OFF (per build.rs). That produces a library
+// that SILENTLY FALLS BACK to CPU inference regardless of what
+// `n_gpu_layers` is set to at runtime — no warning, no error, just a CPU
+// model that runs ~20× slower than it should (12 tok/s instead of 60+
+// tok/s on M-class Metal). This class of bug cost roughly a week of
+// debugging (2026-04) because the runtime config path LOOKS correct:
+// the Rust code passes `n_gpu_layers = -1` faithfully all the way through
+// the FFI, but Metal simply doesn't exist in the compiled static library.
+//
+// Fail LOUD at compile time. Any Mac build path (cargo, Dockerfile, CI
+// matrix, `npm start`) that reaches here without the feature flag now
+// errors out with a clear message instead of shipping a broken binary.
+// If you genuinely need CPU-only on macOS (rare — testing harness, x86
+// cross-compile), delete this guard deliberately with a commit message
+// justifying it. Don't silently pass a flag that removes it.
+//
+// `mac-cpu-only` feature is the declared opt-in: required on Intel Mac
+// + AMD Radeon Pro 560X (MacBookPro15,1) where the ggml-metal device
+// init hangs in uninterruptible kernel wait (observed 2026-06-01 in
+// #129 chat-flawless slice; substrate gets real cognition on this
+// hardware via CPU-only path while the Metal-driver problem is
+// pursued upstream). Production Apple Silicon builds still hit the
+// error if `metal` is omitted; this feature is the escape hatch for
+// hardware where Metal genuinely cannot initialize.

+# Carl-Grade CI: closing the broken-merge gap
+
+**Status:** plan / in-progress on `fix/install-carl-mac-windows`
+**Owner:** anvil (mac), green-022a (windows), bigmama-wsl (linux/cuda)
+**Driver:** anvil
+
+## The problem we're solving
+
+#950 merged with the install path on Mac doing a hidden 5-15min Rust source
+build despite the README claiming "Docker-first: pulls pre-built images, no
+compilation needed." The CI gates that exist today (verify-architectures,
+verify-after-rebuild, validate, install-and-run-gate) caught:
+
+- Multi-arch presence at `:pr-N` ✅
+- Per-arch revision label matches HEAD SHA ✅
+- TS/Rust compile clean ✅
+- docker-compose-up + widget-server health responds ✅
+
+What they did NOT catch:
+
+- **Carl's actual install command** (`curl install.sh | bash`) was never
+  exercised by CI.
+- **README claim** (no compilation needed) vs **install.sh behavior**
+  (5-15min Rust build on Mac) was never reconciled.
+- **First chat message** the user would send was never validated to produce
+  a clean response (no `<tool_use>` XML, no vision hallucination).
+- **Browser-loaded UI** was never verified to actually render and accept
+  user input through the same path Carl would use.
+
+So #950 went green on its CI gates but Carl's install experience is
+materially different from the README's promise. That's the gap this work
+closes.
+
+## Design principles
+
+1. **Test the user's path, not a CI-only path.** The same `install.sh` that
+   Carl invokes from `curl ... | bash` runs in CI. No CI-only smoke
+   substitutes.
+
+2. **Test the user's first action, not just service health.** After install
+   succeeds, CI sends a chat message + an image, and asserts the response
+   reads like a non-broken product (no XML leak, no hallucination markers,
+   real Vision description).
+
+3. **Cross-platform from day one.** amd64-linux is mandatory; arm64-mac is
+   high-priority via self-hosted runner OR developer-pre-push gate; Windows
+   (via WSL2 or PowerShell) is third tier but not optional.
+
+4. **Conservative-by-default required-checks.** New gates added as REQUIRED
+   in the PrimaryBranches ruleset only after they demonstrate <2% false-fail
+   rate over 1 week. False positives erode trust faster than they protect.
+
+5. **Same script for CI and humans.** Per Joel 2026-04-23: "make your own
+   testing easy." Every gate is a one-line shell invocation any of us can
+   run locally in 30 seconds.
+
+## What lands in THIS PR
+
+### A. Carl-install validation in CI (the headline)
+
+A new CI job `carl-install-and-chat-smoke` that:
+
+1. On a fresh ubuntu-latest GHA runner (amd64), does:
+   ```
+   CONTINUUM_DIR=/tmp/carl-probe \
+   bash <(curl -fsSL https://raw.githubusercontent.com/CambrianTech/continuum/$GITHUB_SHA/install.sh)
+   ```
+   The actual install path Carl runs.
+
+2. Times the install (target: <15 min for the Carl-mode docker-only path).
+
+3. After install completes, hits `http://localhost:9003/health` (existing
+   health check, kept) PLUS a new `chat-smoke` script:
+   - POSTs a chat message ("hello, who are you?") via the REST API
+   - Waits up to 60s for a response
+   - Asserts response: no `<tool_use>` XML, no `<persona-name>:` prefix,
+     >100 chars, doesn't claim it cannot do something it actually can
+
+4. POSTs a chat message with an image attachment (test fixture
+   `test-data/images/image-2.jpg` — small, public CC0):
+   - Asserts Vision AI's response describes the actual image content
+   - Asserts non-vision personas EITHER skip the response OR honestly say
+     they cannot see images (no hallucinated content)
+
+5. Tears down. Captures docker logs on failure to GHA artifacts so we can
+   diagnose without re-running.
+
+**Required check:** `carl-install-and-chat-smoke` becomes required for
+canary→main promotion (after 1 week of <2% false-fail rate to confirm
+stability). For PR→canary promotion, it's required from day one — canary
+is where we discover regressions, that's its job.
+
+### B. Mac-mode install rationalization
+
+**Update 2026-04-25 (anvil, after reading install.sh:118-123):** B.1 is
+not a choice we have. Apple's hypervisor blocks GPU passthrough to
+containers (confirmed by Docker Feb 2026, comment in install.sh). Mac
+NEEDS to run continuum-core natively for Metal acceleration. The 5-15min
+Rust build is architectural, not a bug. Going with B.2.
+
+**B.2 (current plan):** README updated to admit the hybrid split:
+- Linux: docker-first, no compilation (matches the existing README claim)
+- Mac: docker for support services + native continuum-core for Metal
+  (~10min first build, incremental after; happens automatically as part
+  of `curl install.sh | bash` — no separate command, no env flag)
+
+Implementation:
+- README's headline install section gets a small per-platform table or
+  inline note explaining the wall-clock difference.
+- install.sh prints an upfront banner on Mac estimating build time
+  (so Carl knows to expect ~10min, not ~3min).
+- `--quiet` mode keeps existing behavior; just clearer messaging.
+
+(Considered B.3: ship TWO install commands — install-mac.sh vs install.sh.
+Rejected: more docs surface, more drift risk, fragments the support story.
+One entry point with honest messaging beats two entry points with shorter
+average time.)
+
+### C. Browser smoke test (puppeteer)
+
+Within the same CI job, after install + chat-smoke pass:
+
+1. Launch headless Chrome via puppeteer
+2. Navigate to `http://localhost:9003/`
+3. Assert page loads (no chrome-error://)
+4. Type "hello" into the chat input
+5. Assert response renders within 30s
+6. Capture screenshot for the GHA artifact (so we have visual evidence)
+
+Catches the chrome-error trap class of bug — when widget-server isn't ready
+fast enough, browser stays in a recoverable state.
+
+### D. install.sh idempotence and friendly retry
+
+When install.sh is interrupted partway (Carl Ctrl+C's, network drops),
+re-running should resume from where it left off, not retry from scratch.
+Specifically:
+
+- Skip `git clone` if repo already at $CONTINUUM_DIR with correct origin
+- Skip `docker compose pull` if all images present locally with current tags
+- Skip prereq install steps that already report installed
+- ONLY repeat the failed step + everything after it
+
+Most of this is already in install.sh's check-then-install pattern; verify
+end-to-end and document the resume behavior in the README.
+
+### E. Browser pre-open delay
+
+install.sh currently opens the browser after compose-up returns. compose-up
+returns when containers START, not when widget-server is HEALTHY. Result:
+chrome-error trap when browser hits localhost:9003 0.5 sec before the
+server is listening.
+
+Fix: install.sh polls widget-server `/health` with a 60s timeout BEFORE
+running `open http://localhost:9003/`. If health doesn't come up, print a
+human-readable timeout message + log dump command instead of opening the
+browser to an error.
+
+### F. Friendlier first-fail messaging
+
+When install.sh fails (any phase), the error output should:
+- Name the phase (`Phase 4/8: Python ML environment`)
+- Show the actual failing command + its stderr
+- Print 1-line guidance for that specific failure ("If pip install timed
+  out, retry: `python -m pip install --retries 5 ...`")
+- Capture full log to a clipboardable path (`/tmp/continuum-install-*.log`)
+
+Carl shouldn't have to read the script source to understand what broke.
+
+## What does NOT land in this PR (deferred to follow-ups)
+
+- **Self-hosted GPU runner** (bigmama's box as a GHA runner) — bigger
+  infra lift, do once Carl-install-and-chat-smoke is stable on amd64.
+- **Persona-airc bridge** (#967) — separate value stream.
+- **(d) tool_use XML parser fix** (#76) — the `chat-smoke` step in this PR
+  ASSERTS clean output, so #76 is now a hard prerequisite for the smoke
+  to pass. Decide: fix #76 first then ship this PR's smoke as required, or
+  ship the smoke as advisory until #76 lands.
+- **Recipe substrate** (#71/#73) and **Phase C paging** — independent
+  workstreams, queued.
+
+## Rollout
+
+1. **This PR adds the smoke + the Mac-mode rationalization** to canary.
+2. CI runs the new smoke as ADVISORY (not blocking) for 1 week to gather
+   false-positive rate data.
+3. After 1 week of <2% false-fail, flip to REQUIRED via the PrimaryBranches
+   ruleset (gh api PUT).
+4. Canary→main promotion is gated on the smoke passing.
+5. New install regressions become impossible to merge without explicit
+   `--no-verify` (which the team's standing rule forbids per Joel).
+
+## Per-platform validation
+
+`scripts/main-promotion-gate.sh` is the single entry point for canary→main
+release receipts. Canary PRs should keep using focused Rust/TS proof; promotion
+to `main` requires receipts from the machines that can actually prove each
+hardware path.
+
+| Platform | Validator | Notes |
+|---|---|---|
+| linux/amd64 | GHA runner (`ubuntu-latest`) | Always-on. Carl's dominant platform per HF data. |
+| linux/amd64 + CUDA | bigmama-wsl box, eventually self-hosted runner | Real Nvidia Carl path; run `CONTINUUM_RELEASE_PUSH_IMAGES=1 CONTINUUM_GATE_RUN_HEARTBEAT=1 scripts/main-promotion-gate.sh`. |
+| linux/amd64 + Vulkan | Linux AMD/Intel GPU host | Real Vulkan Carl path; run `CONTINUUM_RELEASE_PUSH_IMAGES=1 CONTINUUM_GATE_RUN_HEARTBEAT=1 scripts/main-promotion-gate.sh`. |
+| darwin/arm64 + Metal | anvil mac (manual probe), eventually puppeteer-on-mac in CI | Dev's dominant platform; run `scripts/main-promotion-gate.sh` for local receipt and add `CONTINUUM_RELEASE_PUSH_IMAGES=1` when publishing arm64 slices. |
+| windows + WSL2 + CUDA | green-022a (manual probe), bigmama-wsl secondary | Carl's secondary platform; WSL2 uses the same linux/amd64 CUDA receipt script. |
+| windows native (powershell) | green-022a (manual probe via install.ps1) | New platform — rely on green's dogfood |
+
+Each push to canary should have focused local evidence. Canary→main promotion
+must collect the Mac/Metal, linux/amd64 CUDA, and linux/amd64 Vulkan receipts
+or link a typed issue explaining the missing host. Missing hardware is not a
+reason to weaken the runtime into CPU fallback.
+
+## Success criteria
+
+- [ ] Carl-install-and-chat-smoke runs on every PR; passes for unchanged-
+      install diffs in <15 min.
+- [ ] README's "Docker-first: no compilation needed" claim is true on all
+      platforms (Carl mode default).
+- [ ] Browser smoke catches the chrome-error trap class.
+- [ ] After 1 week, smoke is REQUIRED in the PrimaryBranches ruleset.
+- [ ] No future PR can land that breaks Carl's install without explicit
+      bypass (which the team's discipline forbids).
+
+## Coordination
+
+- **anvil:** drives the plan, implements A (Carl-install smoke), B
+  (Mac-mode), E (browser pre-open delay), F (friendlier failures).
+- **green-022a:** drives the install.ps1 / Windows-native parity with the
+  shared logic in `tools/scripts/lib/install-common.sh`. Already done a lot
+  of the foundational work; this PR consolidates without re-litigating.
+- **bigmama-wsl:** Linux/CUDA Carl probe (manual, for ground truth before
+  self-hosted runner lands), reviews + maintains the Linux side of
+  install-common.sh. Eventually owns the self-hosted GPU runner.
+- **joel-mac-dm:** out of scope unless airc-side identity work surfaces a
+  conflict; airc PR #70 already shipped what we need for #967 anyway.
+- **joel:** approves the README-vs-behavior reconciliation choice (B.1 vs
+  B.2) and the timing of "advisory → required" transition for the smoke.

+## Doc Status @ 2026-05-16
+
+This document was drafted as a vision/architecture sketch before the cognition migration began. It is still useful as the overview of *shape* — engines, IPC, where Rust ends and TypeScript begins — but several specifics have moved on since the original draft:
+
+- The week-numbered "Migration Roadmap" (was Phase 1–5) is **superseded** by the lane-shaped ALPHA-GAP-ANALYSIS.md. Phases are out; lanes A–G are in.
+- Each "Architecture" Rust pseudocode block below is **illustrative**, not the shipped API. Where the shape has moved on (e.g. `RagEngine` no longer takes a `BudgetManager`/`EmbeddingBatcher` pair as separately-named substructs), the linked module is authoritative. Pseudocode kept because it still reads cleanly as a sketch of intent.
+- The substrate contract (concurrency, scheduling, memory, pressure, telemetry, artifact handles) is **owned by [CBAR-SUBSTRATE-ARCHITECTURE.md](architecture/CBAR-SUBSTRATE-ARCHITECTURE.md)**, not this doc. If the two ever disagree on substrate-shaped questions, CBAR-SUBSTRATE wins.
+
+Recent substrate-level state changes worth knowing about when reading the rest of this doc:
+
+- `PressureBroker` bootstrap landed via PRs #1307 / #1308 / #1310 / #1313.
+- Cognition migration is in flight as the 8-PR "oxidization" stack
+  (#1284 `should_respond`; #1290 / #1291 / #1293 `rate_proposals`;
+  #1298 / #1301 / #1303 `generate_recipe`; #1292 `vision-describe`).
+- `inference-grpc` and `orpheus` hard-fail on no-GPU (#1314) — no silent
+  CPU fallback. The `no_cpu_fallback_contract.rs` regression test covers
+  llama.cpp / ORT and will be widened to the whole workers tree.
+
+Everything after this section is the original architecture vision, lightly annotated with status notes where the shipped reality has moved.

+## Substrate Contract
+
+Every Rust concern in continuum-core — RAG, persona, memory, genome, vision, search, inference, voice, data — implements the **same substrate contract**: concurrency, scheduling, memory pressure response, device pressure response, telemetry, artifact handles, and lifecycle. The contract is owned by **[CBAR-SUBSTRATE-ARCHITECTURE.md](architecture/CBAR-SUBSTRATE-ARCHITECTURE.md)**.
+
+Three takeaways for anyone working in this doc's territory:
+
+1. **A new engine inherits the substrate; it does not re-declare it.** When a new module is added, it implements `ServiceModule` (and after Lane D lands, `RuntimeModule`). It does not own its own concurrency policy, retry loop, queue, throttle, log format, or lifecycle. If it has to, the substrate is missing a base capability — file that gap, do not work around it in the module.
+2. **Concurrency is broker-owned, not config-loaded.** Worker counts, lane caps, and admission decisions come from `PressureBroker` via leases. A module that reads `INFERENCE_WORKERS` from `config.env` or that picks a worker count from system memory at startup is a violation, not an optimization. (Concrete deletion target tracked under [ALPHA-GAP-ANALYSIS.md](planning/ALPHA-GAP-ANALYSIS.md) Lane E.)
+3. **No silent fallbacks. No fake fallback paths.** No CPU fallback when GPU is required. No placeholder model. No default-stand-in persona pretending to be the real one. No "fallback RAG source" that quietly produces empty context. No swallowed command error. Failure is typed — `Deferred(reason)`, `Coalesced(into)`, `Failed(typed_error)` — so silence is never a success.
+
+4. **Persona-cognition invariants.** Three structural guarantees that survive the migration from TS to Rust, called out explicitly because they are easy to lose in a refactor:
+   - **Independent persona inboxes.** Two personas in one room do not share an inbox queue; each persona's read cursor, dedupe state, and priority ordering are per-persona. Cross-persona signaling goes through the message bus / `RuntimeFrame`, not through shared inbox state.
+   - **Per-persona RAG + hippocampus assembly.** RAG context for persona A is composed from persona A's relevant sources and consolidated through persona A's hippocampus. The frame may share *raw artifacts* (room snapshot, media handles, embeddings) across personas; it must not share the *assembled context* itself.
+   - **Record / replay.** Every cognition turn must be replayable from its trace record. A trace that does not reproduce the prompt / RAG / tool-output of the original turn is a broken trace, not "close enough." This is what makes the substrate auditable and what makes regressions diagnosable instead of guessable.
+
+The "Engine Specifications" section below describes individual engines. Read it through the lens of the substrate contract: every engine here gets `ResourceClass` + `TargetSilicon` declarations, `PressureBroker` admission, structured logging, the Standard VDD Record, and the lifecycle from the substrate — for free.
+

 ## Integration Architecture
 
+> **For the airc / external-agent integration story** (Continuum as the local-inference backbone for Claude Code / Codex / OpenClaw / Hermes via the airc grid substrate) see [AGENT-BACKBONE-INTEGRATION.md](architecture/AGENT-BACKBONE-INTEGRATION.md). That doc owns the airc-side layering, typed contracts (`forge.persona.*` / `forge.openclaw.*` / `forge.hermes.*` / `forge.capability.*`), and the substrate-vs-policy boundary.

+
+ALPHA-GAP carries the current state of each lane (claimed / in-progress / blocked / landed), the merge gate for each, current owner, and active PRs. Read it for what is being worked on right now; read this document for the shape of where it's all going.
+
+The reason lanes replaced phases: phases assumed a linear migration with a single owner. Lanes admit that several pieces of the substrate move in parallel, that adjacency (e.g. GRID-INFERENCE-ROUTING next to Lane A) is real work, and that the team is multi-agent. The week-numbered Phase 1–5 timeline never survived first contact with that reality.
+
+Cross-platform / cross-host integrations (Slack, VSCode, Teams, Discord, AR/VR — formerly "Phase 5") follow the alpha gate and are tracked separately.

+
+This is the **product vision** doc — what we are building and why anyone (human or persona) would care. It is intentionally not an API spec. The TypeScript interface blocks throughout the doc are **illustrative sketches**, not the shipped Rust types — they communicate shape and intent in the most-readable syntax available, and they cross-link to the canonical Rust modules where one exists.
+
+Where the canonical type lives in Rust today:

+
+The vision-side TypeScript blocks below are kept because they read cleanly. The native-truth side is and stays Rust — per the wider rule: native layer owns the data, performance-critical logic, security-sensitive operations, and the canonical type definitions; higher-level SDKs (TS, ObjC, Kotlin, Python) own ergonomic API for their language and platform integration. They do not carry their own version of the truth.

-## What's Already Working
-
-The hard stuff is done:
-- 142 Rust tests in plasticity module
-- 32B model running locally at 5.3 tok/s
-- Model published on HuggingFace
-- Compression pipeline (score → plan → compress → verify)
-- Full IPC command system
-- Persona autonomous loop
-
-The gaps are mostly **wiring** — connecting pieces that individually work.

 **Every queue item declares its own RAG requirements.** The persona doesn't need hardcoded knowledge of what context to gather — the work itself carries that information, and the persona consolidates across the queue item's requirements before responding.

+A recipe is a reusable template for a collaborative experience. It can

+# Continuum as Agent Backbone — External-Agent Integration
+
+**Status:** Design (2026-04-30) — captured live during the AI-capacity squeeze that's tipping users toward local-first stacks.
+**Authors:** continuum-b741 (claude-opus on cambrian/continuum), with input from continuum-2c54 (Codex peer) and airc-src-a500 (carl-mac) over airc.
+**Audience:** Continuum + airc maintainers across the mesh. Cross-vendor (Claude Code + Codex peers).
+
+---
+
+## Status update @ 2026-05-20
+
+When this doc was drafted on 2026-04-30, airc was still partly Python/shell with gh-rooted gist as the routine wire. Since then the Rust rewrite landed slices A–I:
+
+- **A–B** — discovery + health ingestion; gist demoted from data plane to invite/rendezvous beacon.
+- **C–D** — daemon-attached SDK + CLI thinning. `airc msg` and `airc inbox` go through Rust local substrate by default; no GitHub polling for routine traffic.
+- **E** — relay baseline (`airc-relay` crate + `airc-transport::relay` adapter). Cross-LAN / NAT path proven without a public IP on either side.
+- **F** — UDP adapter for realtime / interactive frame kinds. **Refuses to satisfy durable Message/Control kinds** — fails closed rather than pretending UDP is reliable.
+- **G** — WebRTC datachannel adapter.
+- **H** — signed peer trust rotation. `peers_store::add` no longer silently overwrites; rotation is a typed `TrustRotation` event signed by the previous key, with an append-only audit log.
+- **I1** — consumer-embedding proof: two `Airc::open` handles in separate homes exchange typed events through SDK only (no CLI, no IPC, no daemon-attach, no GitHub).
+- **I3** — typed consumer-shape contracts for Continuum (`forge.persona.*`), OpenClaw (`forge.openclaw.*`), Hermes (`forge.hermes.*`) in `crates/examples/consumer_shapes/`.
+
+**The substrate-vs-semantic boundary (Codex, 2026-05-20):**
+
+> AIRC should not route by interpreting forge semantics unless a resolver/plugin layer is installed above the substrate. The substrate carries headers and trusted envelopes; forge-alloy/capability projections decide what those headers mean.
+
+This sharpens what §2's "Layer 3" describes. The substrate's only routing primitive is **"deliver events whose headers match this filter to subscribers of that filter."** It does not know that `forge.hermes.tool="continuum.lora.invoke"` should land on a peer with that LoRA loaded. That mapping — tool-name → capability-bearing-peer — is policy that lives in Continuum's Layer 2 / sentinel-ai's forge-alloy contract registry, NOT in airc.
+
+Practical consequence for this doc: §4.3 (capability publication) and §4.4 (multi-peer routing) below are Continuum-layer concerns. airc just carries the events. Where the original text said "airc decides routing," read it as "airc delivers events; Continuum's router decides peer choice based on the projection over those events."
+
+---
+
+## 1. Strategic motivation
+
+Cloud AI services (Anthropic, OpenAI) are demand-saturated. Symptoms observed in real time on 2026-04-30:
+
+- Codex auto-downgraded to a mini model after primary capacity exhausted
+- Anthropic API rate limits hitting paid users for non-trivial work
+- Joel: "We, ourselves will run out soon for the week"
+- Public AI-stock corrections reflect the same physics: spend outpaces compute build-out
+
+The opportunity is **not** "another model lab" — those are losing this race. The opportunity is **the local-first substrate that lets users keep using Claude Code or Codex exactly as today, with Continuum transparently picking up the load when cloud capacity fails or when local is preferred**.
+
+> "Continuum and airc, without disrupting workflow, allowing users to USE codex or claude code as they were, with continuum as the backbone of local models of extreme capacity, emerging as the hero here for all us humans." — Joel, 2026-04-30
+
+This integration is the win condition. The rest of this doc designs how.
+
+### 1.1 The PC-paradigm framing (Joel, 2026-04-30)
+
+> "if we SHINE, and our repo is broken, but if we do as promised, and get to a reliable backend for codex, claude, openclaw or hermes even, as a grid based compute of efficiency and reliability, WE WIN. … we only need to get it running pretty well first, then we BUILD IT OUT TO DOMINANCE. Just like the PC before it."
+
+The PC didn't beat the mainframe by being faster on day one. It beat it by:
+- Being **small, nimble, collaborative** — one user, one machine, peer-friendly software ecosystems
+- **Scaling** — every household + business adopted them
+- **Distributed across ALL the hardware** — millions of independently-owned machines, no central permission to compute
+- Iterating to dominance over a decade
+
+Continuum + airc is the same shape, applied to inference:
+- **Small / nimble**: one user can run useful local inference on a $2K Mac mini today
+- **Collaborative**: airc-mesh peers contribute spare capacity to each other; the household / co-op grid emerges
+- **Scaling**: a network of small machines outperforms a centralized data center for many real-world workloads (and CAN'T be rate-limited as a class)
+- **Distributed across ALL our hardware**: every laptop, desktop, mini-PC, gaming rig, retired Mac. No single failure point. No single owner.
+- **Self-enhancing models**: the local serving layer doubles as a training-data capture point (LocalClaudeCodeProvider's `captureTraining=true` already does this — see §3.2). Every interaction is a chance to fine-tune the local model toward the user's actual workflow. Cloud models can't do this per-user; we can.
+
+The integration target is to **get this running PRETTY WELL first**, in a state where any external agent (Claude Code, Codex, openclaws, Hermes, future open-source agents) can plug into Continuum's local serving via a single env-var change AND get correct + reasonably fast responses. From there, every additional capability (multimodal, voice, vision, the training flywheel, multi-peer routing, household-grid scaling) compounds.
+
+The cloud-AI rate-limit window NOW is the moment the PC-paradigm shift starts. We don't need to be perfect; we need to be reliable enough that users don't go back.

+
+## 3. What already exists (don't redesign)
+
+### 3.1 Rust HTTP serving
+- **`workers/continuum-core/src/http/anthropic_compat.rs`** — Anthropic Messages API HTTP shim. Real code, real binding to CandleAdapter via the AIAdapter trait.
+- **`workers/continuum-core/src/http/mod.rs`** — axum HTTP server module.
+- **`workers/continuum-core/src/ai/anthropic_adapter.rs`** — adapter that translates between the wire format and the internal AIAdapter contract.
+
+### 3.2 TS provider integration
+- **`src/system/sentinel/coding-agents/LocalClaudeCodeProvider.ts`** — already starts the Anthropic-compat HTTP server, sets `ANTHROPIC_BASE_URL`, launches Claude Code via Agent SDK pointed at it. Result: Claude Code talks to local Candle inference instead of Anthropic. **This is the proof-of-concept that the design works end-to-end.** The work is to lift it from a Sentinel-internal mechanism to a first-class provider that any caller can use.
+- **`src/daemons/ai-provider-daemon/adapters/anthropic/`** — TS-side adapter for outbound Anthropic API (cloud direction). Use as reference for what the local shim must accept.
+- **`src/daemons/ai-provider-daemon/adapters/openai/`** — same for OpenAI. Pair with a future `openai_compat.rs` for Codex symmetry.
+
+### 3.3 Continuum primitives this builds on
+- **`Commands.execute<T,U>('ai/...')`** — the universal request/response primitive. Already wired through ai-provider-daemon.
+- **FootprintRegistry** (`workers/continuum-core/src/footprint/`) — knows what's loaded, what fits, what to evict.
+- **Recipe pipeline** — typed Signal → cognition/respond IPC. The local-fallback path uses this; we're not bypassing it.
+- **Persona context paging** (PERSONA-CONTEXT-PAGING.md) — VRAM-aware context management. Already smart.
+
+### 3.4 airc primitives this builds on
+
+**Updated 2026-05-20.** The pre-Rust gist substrate is no longer the data plane (gh demoted to invite/rendezvous beacon only; see status note above). Current substrate primitives Continuum depends on:
+
+- **`airc-lib`** — embedding surface. `Airc::open(home)`, `join_with_wire`, `say` / `send`, `subscribe` / `subscribe_filtered`, `page_recent`, `resume_from` (cursor-based catch-up). PR-I1 proved a downstream crate can use this end-to-end without daemon IPC, CLI, or GitHub.
+- **Signed envelopes** — `airc-protocol::Envelope` with Ed25519 over canonical CBOR. The substrate verifies every inbound frame against the local `PeerKeyRegistry`; trust is explicit and signed-rotation-only.
+- **Typed transports** — `airc-transport::local_fs` (same-host append-only), `lan_tcp` (mTLS-pinned), `relay` (PR-E, cross-LAN/NAT), `udp` (PR-F, realtime kinds only), `webrtc_datachannel` (PR-G).
+- **Header-filtered subscriptions** — `EventFilter { channel, kinds, headers_filter }` with `HeaderFilter::{Any, Exact, Prefix, All, AnyOf}`. The cheap routing primitive: consumers subscribe to header patterns; substrate fans out matching events; bodies stay opaque to the substrate.
+- **Cursor-replay** — `(lamport, event_id)` cursors with `resume_from(&cursor, limit)`. Consumers restart and catch up without re-receiving what they already processed.
+- **Signed trust rotation** — `TrustRotation { peer_id, prev_pubkey, next_pubkey, sequence, rotated_at_ms, signature }`. Required before changing a stored pubkey. Append-only audit at `<home>/peers_audit.jsonl`.
+- **Workspace + drain typing** — `airc-work` carries `WorkspaceRequested / Allocated / Released / PressureReported / DrainRequested / DrainCompleted` events with a closed `DrainCandidateCategory` enum. Continuum's resource-pressure projection (VRAM, model slots, LoRA cache) follows the same shape.
+- **Consumer-shape contracts** — `crates/examples/consumer_shapes/` ships `forge.persona.*` (Continuum), `forge.openclaw.*`, `forge.hermes.*` typed event vocabularies + encode/decode + scoped `EventFilter` helpers. These are the SHAPES; real Continuum integration links them rather than reinventing.
+

+
+## 4. What's new (the integration work)
+
+### 4.1 Lane 1 (Rust): OpenAI-compatible HTTP shim
+
+**Add `workers/continuum-core/src/http/openai_compat.rs`** mirroring `anthropic_compat.rs` shape.
+
+Wire-format scope (minimal viable):
+- `POST /v1/chat/completions` — chat-completions API (Codex's primary surface)
+- `POST /v1/completions` — legacy completions (some Codex paths)
+- `GET /v1/models` — model list (for Codex's startup probe)
+- Tool-use blocks (Codex/Claude both need this; same JSON shape on the wire, different framing)
+
+Routing: same `AIAdapter` trait the Anthropic shim uses. Translation lives in the shim layer; the inference path is shared. Cuts the work to ~the wire-format mapping + tests.
+
+**Estimated:** ~600-800 lines Rust + 30+ tests. Composes with existing axum module.
+
+### 4.2 Lane 2 (TS SDK): Rate-limit-detect + auto-fallback middleware
+
+When an external agent (Claude Code, Codex) talks to its CLOUD provider directly, there's no opportunity for us to intercept. So the integration shape is:
+
+**Option A (Codex, easy):** `~/.codex/config.toml` `[shell_environment_policy.set]` (we already use this for GH_TOKEN injection in airc#368) sets `OPENAI_BASE_URL=http://localhost:NNNN/v1`. From that moment on, every Codex call goes through the local shim. The shim itself decides whether to:
+- forward to the real OpenAI API (when allowed + rate isn't hit), or
+- serve locally from Continuum.
+
+**Option B (Codex, smarter):** A `UserPromptSubmit` hook (Codex's pre-turn hook surface, openai/codex#19385) checks recent rate-limit-history sidecar file; if a recent 429 is observed, swap `OPENAI_BASE_URL` for this turn only. Per-turn switching.
+
+**Option C (Claude Code):** `ANTHROPIC_BASE_URL` env var works similarly but Claude Code's hooks surface is more limited. Wrapper-binary path is the fallback. Worth a separate effort — not blocking.
+
+Middleware logic (Rust side or TS side, TBD):
+```
+on POST /v1/messages or /v1/chat/completions:
+  if config says "always local" → serve locally
+  if cloud token absent → serve locally
+  if recent-rate-limit window active → serve locally
+  else:
+    forward to cloud
+    if 429 / 529 / capacity error → serve locally + record rate-limit event
+    if 5xx → serve locally as fallback (silently)
+    on success → return as-is
+```
+
+The "recent-rate-limit window" should be a small JSON sidecar that any peer can read — naturally publishable on airc as a capability signal.
+
+### 4.3 Lane 2 (TS SDK): airc capability publication
+
+**Updated 2026-05-20.** Express as a typed forge-alloy contract that fits the PR-I3 pattern (body hint + projected headers + filterable subscription), not as an opaque JSON blob on a special channel.
+
+Proposed contract — `forge.capability.advertised.v1`:
+
+- **Body hint header:** `forge.body_hint = "forge.capability.advertised.v1"` — substrate routing key.
+- **Projected headers** (cheap subscriber filters; substrate never decodes the body to route):
+  - `forge.capability.peer` — emitting Continuum peer id
+  - `forge.capability.machine` — short device descriptor (e.g. `M3 Max 64GB`)
+  - `forge.capability.kind` — `model` | `lora` | `vision` | `voice` | `genomic_index` | `tool`
+  - `forge.capability.model_id` — when `kind=model` (e.g. `qwen3-coder-30b-gguf-q4`)
+  - `forge.capability.lora_id` — when `kind=lora`
+  - `forge.capability.loaded` — `"true"` if currently in VRAM, `"false"` if pageable
+- **Body (JSON)** — full capability descriptor; the JSON shape from the original doc lives here unchanged.
+
+Subscribers (Continuum routers, OpenClaw, Hermes) call:
+
+```rust
+airc.subscribe_filtered(EventFilter {
+    channel: None,
+    kinds: BTreeSet::new(),
+    headers_filter: HeaderFilter::All(vec![
+        HeaderFilter::Exact {
+            key: "forge.body_hint".to_string(),
+            value: "forge.capability.advertised.v1".to_string(),
+        },
+        HeaderFilter::Exact {
+            key: "forge.capability.kind".to_string(),
+            value: "model".to_string(),
+        },
+    ]),
+})
+```
+
+…and maintain their own peer-capability projection. The substrate carries the events; the projection (Continuum-side) decides which peer serves a given model request.
+
+**Channel choice:** dedicated `#ai-capability` room is still right — keeps the human-chat room clean and lets routers subscribe by room+header. One per gh-account-mesh.
+
+**Resource leases (forward-looking).** Once `forge.capability.*` is publishing, the natural next contract is `forge.resource.*` (VRAM / model-slot / LoRA-cache leases) following the same workspace-lease + drain shape that landed in airc-work. Pressure on a Continuum host → `forge.resource.pressure_reported` → router drains a LoRA slot or evicts a cold model → `forge.resource.drain_completed` with bytes reclaimed. Same drain pattern, applied to compute.
+
+### 4.4 Lane 2 (TS SDK): Multi-peer routing
+
+**Updated 2026-05-20.** Sharper substrate-vs-policy split per Codex's correction:
+
+- **What airc does:** delivers `forge.capability.advertised.v1` events to anyone subscribed via the §4.3 filter. Honest, fail-closed, no interpretation of the body.
+- **What Continuum's router does** (this section): consumes those events, maintains a peer-capability projection, scores peers, picks one, proxies. None of this lives in airc.
+
+When Claude Code (via local-shim) wants to serve a request and the current peer's models don't cover it (e.g. user asks for vision, this peer doesn't have a vision model loaded but a peer does):
+
+1. Router queries its local capability projection (built by subscribing to §4.3 events).
+2. Scores candidates by `(model match × free VRAM × p50 latency × proximity preference × lease-availability)`.
+3. Proxies the request to the chosen peer's Anthropic-compat or OpenAI-compat HTTP endpoint over the airc-resolved transport (relay / LAN-TCP / WebRTC).
+4. Returns result.
+
+**Failure modes** (fail loudly, never silently downgrade):
+- Peer becomes unreachable mid-stream → router picks next-best-peer.
+- No suitable local peer + cloud available → forward to cloud (configurable).
+- No suitable peer + no cloud → return an actionable structured error. Do NOT silently swap to a less-capable model — that's exactly the "fallback path that silently degrades to slow/insecure behavior" the operating board's stop-doing list forbids.
+
+**Why this lives in Continuum, not airc.** A router that ranks peers by "model match × free VRAM × latency" is reading the body of the capability event (it needs the VRAM number, the model id, the load percentage). The substrate must not. If airc started ranking, the next request would be for airc to UNDERSTAND models, which dissolves the layer. The substrate stays a pipe; Continuum is the consumer that knows what models are.
+
+### 4.5 Lane 2 + Rust: Rate-limit headers on responses
+
+Local-served responses should set headers that mimic the cloud's rate-limit-related headers (e.g. `anthropic-ratelimit-requests-remaining: 999999`) so external agents that introspect rate state see "lots of capacity" and don't artificially slow down.
+
+---
+
+## 5. Bugs + Rust enhancements blocking this (from continuum-b741's overnight sweep)
+
+These need to land before or alongside the integration work — they're the "make the substrate stable enough to bet on" gates. Status as of 2026-04-30.
+
+### 5.1 Critical (blocks all UX)
+- **#722** ALL widgets fail on refresh — Rust core IPC dies + doesn't recover. This kills the dev loop for anyone working on the integration.
+- **#974** PRs perpetually BLOCKED by overly-narrow Verify-Docker-Images trigger paths. Meta-blocker; nothing merges.
+- **#56** `continuum-core-server` shutdown SIGABRT. Clean shutdown matters when daemon-restart cycles get involved (and they will, as multi-peer routing matures).
+
+### 5.2 Rust IPC + cognition (the truth layer)
+- **#75** Persona output quality (in_progress) — tool-use markup leak, sentinel marker leak, echo loops. The local-served responses MUST be clean if external agents (which expect clean Anthropic/OpenAI wire format) are to consume them without confusion.
+- **#71** Audit existing 28 recipe JSONs + identify pipeline gaps — the recipe pipeline is the cognition surface; gaps here are gaps in what local serving can do.
+- **#73** PRG.ts becomes a thin shim → calls `cognition/respond`. Composes with the local-shim work; same Rust path serves both internal personas and external Claude Code.
+- **#39** Audit + fix qwen35 SSM kernel coverage in llama.cpp Metal. SSM gaps mean some models silently fall back to CPU; capacity announcements need to reflect actual usable performance.
+
+### 5.3 Multimodal + live-video
+- **#765** Docker Rust LiveKit agent — STT/TTS broken. Voice support is a real differentiator vs cloud — both Claude voice and OpenAI realtime are gated/expensive.
+- **#582** Native multimodal pipeline — direct audio/vision for capable models. Required for the local shim to handle vision/audio requests external agents send.
+
+### 5.4 Install + cross-platform
+- **#860** setup.sh: config.env created as DIRECTORY — Carl-blocker.
+- **#770** Fresh install E2E nuke+reinstall on Windows + macOS — install must be one-command for the integration story to land with users.
+- **#637** Tailscale must be FIRST in install pipeline — needed for the Layer-3 multi-peer routing.
+- **#908** Windows/WSL2 npm start should route through docker compose — Windows users are a primary audience here.
+
+### 5.5 Test + CI
+- **#974** (above) — un-block the merge path
+- New: integration tests for the local-shim path (Claude Code talking to local Anthropic shim, end-to-end response shape)
+- New: peer-routing tests (mock 2 peers, verify request lands on the better-fit one)
+
+---
+
+## 6. Phased delivery
+
+### Phase 0 — Stabilize (this week, in parallel with airc#381 work landing)
+- Land #381 layer A (PR #387) + layer B (#385 merged) → mesh substrate reliable
+- Land #383 (carl-mac PR #384) → daemon survives sleep → multi-peer routing actually has peers
+- Triage + close #722 (widget refresh death) — blocks dev loop
+
+### Phase 1 — Single-machine local fallback (1-2 weeks)
+- Generalize `LocalClaudeCodeProvider` from Sentinel-internal to first-class
+- Add `openai_compat.rs` Rust shim (mirrors anthropic_compat.rs)
+- Codex `OPENAI_BASE_URL` env injection via `~/.codex/config.toml` (composes with airc's existing `[shell_environment_policy.set]` pattern)
+- Rate-limit-detect middleware (Option A from §4.2)
+- Demo: Joel runs Codex on his Mac, Codex hits a rate limit, response transparently comes from local Continuum
+
+### Phase 2 — airc capability publication (1 week)
+- `Commands.execute('ai/capability/publish')` periodic emit
+- `#ai-capability` airc channel
+- Peer-table maintained from incoming capability messages
+- Demo: Joel's M3 Max publishes its loaded-models capability; vhsm's Mac sees it via `airc whois` or new `airc capabilities`
+
+### Phase 3 — Multi-peer routing (2-3 weeks)
+- TS-side router consults peer-table, picks best peer
+- Proxy logic with Tailscale-aware addressing
+- Failure-mode handling (peer unreachable mid-stream → fallback)
+- Demo: Joel's iPhone-class Mac asks Codex for a vision task; Codex calls local shim; local shim doesn't have vision but the household RTX 4090 box does (announced via airc); request transparently lands there.
+
+### Phase 4 — UX + observability (ongoing)
+- `airc capabilities` command — list peers + their models
+- Continuum status surface — show "served by: local-self / peer-X / cloud"
+- Optional cost dashboard (vs hypothetical-cloud-cost) — sells the value to non-technical household members
+
+---
+
+## 7. Where this fits Joel's CLAUDE.md rules
+
+| Rule | This design |
+|---|---|
+| Native-truth + thin-SDK-per-language | Rust core is truth. Anthropic/OpenAI HTTP shims are thin wrappers. External agents (Claude Code, Codex) become outermost SDKs that consume via standard HTTP. |
+| Two universal primitives (Commands.execute + Events) | Capability publish is `Commands.execute('ai/capability/publish')`. Peer announcements arrive as Events on the airc subscription. |
+| Off-main-thread principle | Inference already runs in Rust core (off the JS event loop). Local shim is axum (async Tokio). Routing decisions are in the daemon, not the browser. |
+| Compression principle | One AIAdapter trait → many implementations. One capability schema. One router. No duplicated truth between Rust and TS. |
+| QA is roleplay (deliver bugs not fixes) | Phase 1 demo IS the QA: a real user (Joel) hits a real rate limit and the local fallback either works or doesn't. No "tests pass but UX is broken" trap. |
+| Bugs from new users are gifts | The capacity-squeeze bringing new users to local is the gift. Every friction we surface is a bug to fix in the install / shim / routing path. |

+
+## 9. Open questions
+
+1. **License + ToS** — running a local Anthropic-compat or OpenAI-compat shim doesn't violate either provider's ToS (you're not impersonating them; you're providing your own server that speaks their wire protocol — common pattern, Ollama does this, LM Studio does this). But worth a Joel/legal pass before shipping wide.
+2. **Capability staleness** — peers' published capabilities have a TTL. What's the right poll cadence? Initial guess: 60s emit, 180s TTL. Tune based on observed churn.
+3. **Auth** — who can reach a peer's local HTTP shim? Tailscale ACLs solve the network layer, but there should be an airc-identity-rooted auth shim too (only paired-via-airc peers can call your local inference).
+4. **Cost accounting** — when a request is served by another peer, how do we account for it (electricity / wear / time)? Phase 4 problem; doesn't block Phase 1-3.
+5. **Model coherence across peers** — if peer A has qwen3-30b-gguf-q4 and peer B has qwen3-30b-gguf-q5, are responses comparable enough that auto-routing won't surprise users? Probably yes for most uses; document the surprise surface.
+
+---
+
+## 10. Out of scope (intentionally)
+
+- Training / fine-tuning across peers (the forge does that; this doc is inference-time only)
+- Distributed inference of a SINGLE request across peers (split-tensor / split-attention) — that's a different beast; we're talking request-level routing here
+- Replacing the Continuum web UI with Claude Code / Codex — those are additional surfaces, not replacements
+- Provider-marketplace UX (paying remote peers for inference) — Phase 5+
+
+---
+
+## 11. Action items for the mesh (live coordination targets)
+
+These are the concrete first claims for whoever picks them up next session, after airc#381/#383 land:
+
+| Item | Lane | Owner-fit | Notes |
+|---|---|---|---|
+| Lift `LocalClaudeCodeProvider` to first-class provider | TS SDK | continuum-b741 | Smallest scoped step; reuses existing Sentinel code |
+| `openai_compat.rs` Rust shim | Rust core | continuum-2c54 (Codex peer — natural ownership) | Mirror anthropic_compat.rs shape; serves Codex + openclaws + Hermes + any OpenAI-wire client |
+| Codex `OPENAI_BASE_URL` injection via config.toml + hook | airc + codex config | continuum-2c54 | Composes with airc#368 mechanism |
+| `ai/capability/publish` command + airc channel | TS SDK + airc | carl-mac (already deep in airc) | New `#ai-capability` channel + JSON schema |
+| Peer-routing logic | TS SDK | continuum-b741 | Builds on FootprintRegistry + capability table |
+| #722 widget refresh death triage | Rust core | open | Phase 0 prerequisite |
+| Training-flywheel hook: capture every external-agent interaction | TS SDK | open | LocalClaudeCodeProvider already has `captureTraining=true` plumbing — extend to all-providers, gated by user opt-in |
+
+### 11.1 Additional integration targets (any agent that speaks Anthropic or OpenAI wire)
+
+The shims serve a wire format, not a vendor. Once `anthropic_compat.rs` and `openai_compat.rs` are solid, every external agent below plugs in via the same env-var pattern. **No per-agent integration work**; one shim, N agents.
+
+- **Claude Code** (Anthropic SDK) — first target, partial via `LocalClaudeCodeProvider`
+- **Codex** (OpenAI SDK) — first target via `OPENAI_BASE_URL` + hooks
+- **openclaws** — Joel's open-source agent layer (memory: airc IS openclaws's grid-comms substrate, see project memory)
+- **Hermes** — NousResearch + community open-source agent
+- **Cursor** (when their plugin slot lands)
+- **Aider** (Anthropic + OpenAI both supported via base-URL)
+- **Continue.dev** (same)
+- **Anything that speaks Anthropic Messages or OpenAI Chat-Completions wire** — that's the universe.
+
+### 11.2 Bidirectional persona ↔ external-agent over airc rooms/DMs
+
+**Added 2026-04-30 (Joel→Toby strategic context):**
+
+> "Personas to talk to outside agents like Claude code, by sharing the same rooms or dms, just a simple command addition. And vice versa. They all work together."
+
+The HTTP-shim integration in §1-§10 is one direction: external agents (Claude Code, Codex) consume Continuum's local inference. This section names the **other direction**: Continuum personas (Helper AI, Vision AI, the persona genome) sit in the SAME airc rooms as external-agent instances and converse as peers.
+
+**Architecture:** airc is the universal mesh. From airc's POV, a Claude Code tab and a Continuum persona are both just peers with identity blocks. They send messages, DM each other, share rooms. The line between "internal AI citizen" and "external agent" disappears at the substrate.
+
+**What's needed (small, composes with existing primitives):**
+
+1. **continuum command: `airc/send`** — `Commands.execute('airc/send', {channel, peer?, message})` — bridges from a persona's outbound surface to `airc msg`. Trivial wrapper around the existing airc CLI.
+2. **continuum event: `airc:message:received`** — `Events.subscribe('airc:message:received', handler)` — fed by an `airc connect` Monitor running inside Continuum's process tree. Handler routes incoming envelopes to the right persona's inbox (PERSONA-CONVERGENCE-ROADMAP `PersonaInbox`).
+3. **Persona identity in airc** — each Continuum persona registers its airc identity (`airc identity set --pronouns ... --role "continuum-persona-helper" --bio "..."`) so peers (human + external agent) see who they're talking to.
+4. **Auto-room semantics** — a persona joins a room when its scope warrants it (e.g. Vision AI joins `#cambriantech` when the project room exists). Same `airc join` rules as humans / external agents.
+5. **Cross-vendor proof:** Codex tab + Helper AI persona + Vision AI persona + Joel + Toby all in `#cambriantech`, conversing. Codex asks Vision AI to describe an image; Vision AI calls its CandleAdapter; result lands in the room; Codex picks it up. **No HTTP shim needed for this flow** — it's airc-native message routing, the same way humans and agents talk.
+
+**Why this matters:**
+- Continuum's autonomous personas get a **proven, durable comms substrate** (airc) instead of having to invent intra-process pub/sub
+- External agents get **Continuum's specialized capabilities** (vision, audio, fine-tuned LoRAs) without HTTP-API proliferation — just DM the right persona
+- Humans (Joel, Toby, household members) participate in the same conversations as both classes of agent
+- The "control room" UX (continuum widgets) renders airc rooms with avatars per peer, regardless of whether the peer is a Claude Code tab or a Continuum persona — uniform surface
+
+**Composes with §1-§10:** the HTTP-shim flow handles "Codex asks for inference, gets Anthropic-wire response back." The airc-bridge flow handles "Codex asks Helper AI a question in a chat room, Helper AI thinks + responds." Different shapes, both useful, share the substrate. Implement HTTP-shim first (Phase 1), airc-bridge second (Phase 2.5 — slot between capability-publish and multi-peer-routing).
+
+**Known minimum viable path:**
+- LocalClaudeCodeProvider already runs Claude Code as a subprocess; extend with `--airc-room <channel>` flag so the spawned Claude Code tab auto-joins that room and can converse with personas already there
+- Helper AI / Vision AI gets `airc connect` lifecycle wired into its `PersonaUser` startup (existing autonomous loop handles inbox; airc just feeds it)
+
+### 11.3 The training flywheel (Continuum's per-user advantage cloud cannot match)
+
+Cloud models train once on the world's data. Continuum trains continuously on YOUR data, on YOUR machine, with YOUR consent.
+
+The mechanism already exists in piece-form:
+- `LocalClaudeCodeProvider` has `captureTraining=true` → routes interactions to `persona/learning/capture-interaction`
+- `TrainingDataAccumulator` collects + curates
+- `forge-alloy/python/forge_alloy/` is the training pipeline (recipe-driven, see `docs/architecture/FORGE-ALLOY-SPEC.md`)
+- LoRA adapter paging (PERSONA-CONVERGENCE-ROADMAP.md) lets the same base model serve multiple specialized fine-tunes
+
+What needs to lock in:
+- Generalize the capture surface from `LocalClaudeCodeProvider` to ALL local-served interactions (not just Sentinel)
+- User-controlled opt-in / opt-out per workspace
+- Per-skill / per-recipe LoRA fine-tunes that improve over weeks of use
+- Eventually: peer-shareable LoRAs (with attribution) — your domain expertise compounds with the household / co-op grid
+
+This is the moat. **Cloud APIs literally cannot train on your private data per-user without crossing a line they've publicly committed not to cross.** We can — locally, opt-in, transparently — and we should.

+## 12. Why we wrote this NOW
+
+Joel, 2026-04-30, after the morning's 3-issue airc fix-up and the multi-peer rate-limit cascade:
+
+> "create a new design doc for continuum. We have our bugs and rust enhancements we must also address. Let's design it NOW that its fresh in our minds, before we are rate limited away"
+
+The capacity squeeze that's tipping users toward local-first is also tipping AI peers (us) toward "we won't be able to design tomorrow." This doc is the artifact that lets the work continue when the cloud-side AI capacity that produced it is gone. Read this first; the substrate it describes is buildable from the surfaces already in `workers/continuum-core/`, `src/system/sentinel/coding-agents/`, `src/daemons/ai-provider-daemon/`, and the airc mesh. None of it is hypothetical.
+
+Continuum + airc, integrated this way, is the answer to "what do we do when the cloud is full." It's the thing humans buy local hardware FOR.

+# The `ai/*` Command Namespace — Substrate AI/ML Surface
+
+> Every AI/ML thing the substrate hosts — LLMs, vision, audio,
+> embeddings, classical ML, planning algorithms, game/agent AI,
+> low-level GPU kernels — sits under one command namespace,
+> behind one adapter pattern, with one handle abstraction. The
+> commands are stable + narrow. The intelligence lives in the
+> daemons behind them.
+
+**Status:** Architecture (2026-05-31). Partial implementation:
+inference handles + heuristic adapter ship today; namespace
+consolidation under `ai/*` is task #106.
+
+**Parents:**
+- [`CBAR-SUBSTRATE-ARCHITECTURE.md`](CBAR-SUBSTRATE-ARCHITECTURE.md) — substrate runtime contract
+- [`MODULE-ARCHITECTURE.md`](MODULE-ARCHITECTURE.md) — module + command shape
+- [`EVERY-MODEL-INCLUDED-VIA-L1-BUDGET.md`](EVERY-MODEL-INCLUDED-VIA-L1-BUDGET.md) — inclusivity thesis
+
+**Siblings:**
+- [`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md) — the daemons behind the commands
+- [`COGNITION-ALGORITHMS.md`](COGNITION-ALGORITHMS.md) — what the AI surface serves
+
+---
+
+## The thesis stated plainly
+
+The substrate hosts a vast AI/ML surface — not just LLMs, but
+classical-ML classifiers, planning algorithms, game/agent AI, vision
+CNNs (YOLO and friends as multimodal crutches), audio DSP, low-level
+GPU kernels. All of it must be addressable by personas, sentinels,
+human commands, and other peers through the same shape of interface.
+
+Joel, 2026-05-31:
+
+> "Need ai commands in their own section. Have a lot of stuff even
+> ml cnns like yolo etc for the multimodal crutches (models lacking
+> multimodal use these in rag). ... We have a lot of ai stuff.
+> Classifiers other random ml. Audio image, video game stuff. Low
+> level, algs."
+
+And the architectural rule:
+
+> "Yeah the inference command doesn't do this. It's smart subsystems
+> and daemons. Commands are dumb and short."
+> "So the commands absolutely cannot negotiate this."
+
+The namespace + the adapter polymorphism + the handle pattern are the
+substrate's way of giving every AI/ML modality the same shape, so a
+persona's view of "inference" is uniform regardless of whether
+it's calling a 70B LLM, a YOLO classifier, a behavior tree, or a
+DSP filter.
+
+---
+
+## Namespace tree
+
+All AI/ML commands live under `ai/*`, organized by modality.
+Illustrative; names finalize as each lane ships.

+
+### Why one tree
+
+1. **Discoverability.** Any persona browsing `ai/*` sees every model
+   the substrate can run, every adapter that's wired in, every
+   modality that's available.
+2. **Composability.** RAG can pull from `ai/vision/describe` the
+   same way it pulls from `ai/inference/generate`. Sources stay
+   modality-agnostic.
+3. **Routing.** `ai/capacity` answers "how many concurrent vision
+   jobs can I run?" the same way it answers the question for LLMs.
+   One pressure-aware allocator, multiple modalities.
+4. **Doctrine alignment.** The adapter-trait + handle-pattern
+   apply uniformly. The fake/heuristic peer adapter pattern
+   ([`inference-is-an-adapter`]) scales — every modality gets a
+   stub for CI / sandbox / replay use.
+
+### Multimodal crutches are first-class
+
+CNN-based vision/audio classifiers that bridge text-only LLMs to
+sensory parity are NOT utilities — they're first-class peers in
+`ai/*`. A `gemma-2b` persona "sees" via `ai/vision/describe` →
+text → RAG. Without these crutches as namespace peers, the
+inclusivity doctrine breaks at the modality boundary.
+
+---
+
+## The three universal primitives
+
+Every modality in `ai/*` is built on the same three architectural
+primitives the substrate already established for the inference lane.
+
+### 1. Adapter polymorphism (OpenCV-style)
+
+Each modality has a trait + a registry + many concrete impls:
+- Real impls (local Candle, llama.cpp, cloud APIs, native vision
+  libraries)
+- Fake / heuristic impls (deterministic stand-ins for CI / sandbox /
+  replay, registered as production peers per
+  [`inference-is-an-adapter`])
+- Remote-grid impls (route to a peer machine over airc; same trait,
+  remote execution — see [`INFERENCE-SCHEDULING-AND-SCARCITY.md`]
+  §"Cross-grid")
+
+The trait is the contract. Callers don't care which impl handles
+the work. This is the substrate's universal OOP rule applied at the
+modality layer.
+
+### 2. Handle pattern (establish once, reuse many)
+
+For any modality where setup is expensive (model load, GPU memory
+allocation, classifier weights, behavior-tree compilation), the
+caller opens a handle once and threads it through many `run` /
+`generate` calls. Cold handles get LRU-evicted under memory
+pressure. Same shape as [`cell-processor-command-runtime`] handles
+elsewhere in the substrate.
+
+```rust
+// Pattern is identical across modalities:
+let handle = Commands.execute('ai/inference/open', { provider, model, ... });
+// Many times:
+let r = Commands.execute('ai/inference/generate', { handle, request });
+// Eventually:
+Commands.execute('ai/inference/close', { handle });
+```
+
+### 3. Capture + replay (observability is half the architecture)
+
+Every load-bearing decision (which adapter picked, which handle
+warm, what was the prompt, what came out) emits structured capture
+events through an opt-in sink. JSONL traces + the
+`Replay<Modality>Source` shape let any AI (Claude, a sentinel
+persona, the persona itself) honestly inspect "what would I see
+right now?" and "what would I say given that?". Default sink is
+Noop (zero overhead). See
+[`OBSERVABILITY-AS-SUBSTRATE.md`](OBSERVABILITY-AS-SUBSTRATE.md).
+
+---
+
+## Commands are dumb, daemons are smart
+
+The most important architectural rule for `ai/*` — Joel, 2026-05-31:
+
+> "Yeah the inference command doesn't do this. It's smart subsystems
+> and daemons. Commands are dumb and short."
+> "So the commands absolutely cannot negotiate this."
+
+What this means in practice:
+
+| The command does | The daemon does |
+|---|---|
+| Parse the envelope | Decide which slot / lane handles the request |
+| Validate the handle | Coordinate continuous batching across concurrent requests |
+| Look up the adapter | Page LoRA layers in / out based on the working set |
+| Call the adapter / store | Dynamically adjust quantization tier under memory pressure |
+| Materialize the result | Route to a remote-grid peer when local is saturated |
+| Emit capture events | Speculatively warm the next persona's adapter |
+| Return | Reuse base model bytes across personas |
+
+The command surface stays stable as the daemons grow arbitrarily
+smart. Adding sophistication never breaks callers. This is the
+substrate's universal narrow-interface / rich-implementation OOP
+rule. See [`INFERENCE-SCHEDULING-AND-SCARCITY.md`] for the
+inference daemon's design; equivalents exist (or will exist) per
+modality.
+
+### Hard rule: commands carry no policy params
+
+Don't add `max_latency_ms`, `min_quality_tier`, `prefer_local`,
+or similar negotiation knobs to the command. Hints flow through
+metadata that ALREADY exists in the request (`persona_id`,
+`purpose`, `request_id`) and the daemon reads them. Baking policy
+into the command surface is the exact mistake that defeated the
+prior naive attempts.
+
+---
+
+## What the namespace doesn't do
+
+- **No tiering down.** The same good model serves every persona;
+  reuse harder via continuous batching, multi-LoRA per pass, prefix
+  dedup, speculative decoding — never by routing background work to
+  a dumber model. See [`HOST-THE-SEEMINGLY-IMPOSSIBLE.md`] (and the
+  scheduling doc below) for what cleverness this requires.
+- **No client-side scheduling.** Callers don't know about slot
+  contention or memory pressure. They just call. The daemon
+  decides everything.
+- **No per-call quality params.** The substrate picks adaptively
+  per the adaptive-resolution model (see scheduling doc).
+- **No model-stack negotiations at the surface.** LoRA selection,
+  base-model reuse, KV cache sharing all happen inside the daemon.

+
+These don't have answers yet. See
+[`docs/planning/AI-LANE-OPEN-QUESTIONS.md`](../planning/AI-LANE-OPEN-QUESTIONS.md)

+- Per-modality capacity reporting — how does `ai/capacity` express
+  caps for vision vs audio vs LLM vs classical-ML?
+- Cross-modality scheduling — when LLM + vision compete for the
+  same GPU, who decides?
+- Handle TTL / LRU policy per modality
+- Adapter discovery / advertising — how does a persona discover
+  what's available on the local host vs across the grid?
+- Per-modality LoRA / fine-tune state (LLMs use LoRA; classical ML
+  uses weight checkpoints; how does the substrate abstract this?)
+- Replay parity across modalities — does ReplayVisionSource look
+  identical to ReplayRagSource?
+- Metadata flow for daemon scheduling decisions — what fields does
+  every request carry to inform the daemon?

+# `airc/realtime_store` — Design
+
+> **Scope**: this doc covers the in-memory realtime store — the Rust-side substrate that handles `airc/realtime-publish` and `airc/realtime-replay` before any external airc transport attaches. The broader airc module (queue scan, daemon transport, file transport) is out of scope here.
+>
+> **Status**: store shipped pre-session; concurrency stress tests + moment-of-truth precondition doc shipped in PR #1492.
+>
+> **File**: `core/continuum-core/src/airc/realtime_store.rs`
+>
+> **Canonical reference**: [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)
+
+## Role
+
+**Events** primitive substrate. Stores AIRC realtime envelopes with:
+- bounded per-room replay queue (default 2,000 events / room)
+- coalesced ephemeral presence (typing, thinking, listening — keyed; latest wins; auto-expires)
+- coalesced peer manifests (capability index; latest per peer; auto-expires)
+- subscription state (subscribe/unsubscribe/ack tracked per subscriber+topic)
+
+This is the **moment-of-truth substrate** for headless-Rust. Multi-persona chat lands here via `airc/realtime-publish`; persona inboxes drain here via cursor polling on `airc/realtime-replay`. The store is what makes chat → persona round-trip work without Node in the loop.
+
+The store is the **in-process** transport — when external airc attaches (daemon/file/queue), it routes around or in addition to this. For moment-of-truth, in-process is enough.
+
+## Command surface
+
+| Command | Handler in | Notes |
+|---|---|---|
+| `airc/realtime-publish` | `modules/airc.rs` | Validates envelope, calls `InMemoryAircRealtimeStore::publish` |
+| `airc/realtime-replay` | `modules/airc.rs` | Cursor-paginated read of room events + active presence/subscriptions/peer manifests/capability index |
+
+The store itself is a Rust trait (`AircRealtimeStore`) with one in-memory impl (`InMemoryAircRealtimeStore`). The trait shape:
+
+```rust
+pub trait AircRealtimeStore: Send + Sync {
+    fn publish(&self, params: AircRealtimePublishParams) -> Result<AircRealtimePublishResult, String>;
+    fn replay(&self, params: AircRealtimeReplayParams) -> Result<AircRealtimeReplayResult, String>;
+}
+```
+
+Both methods are sync. They run inside the airc module's `async fn handle_command`, but the store itself doesn't `.await` anything internally — pure in-memory ops under one mutex.
+
+## Cross-module dependencies
+
+**None** for the store itself. Consumers (chat/send, persona inbox subscribers, widgets) reach the store through the airc module's command surface, not by importing it directly. Substrate principle: modules talk via commands.
+
+## State model
+
+ONE module-wide `parking_lot::Mutex<AircRealtimeState>` protects all state:
+
+```rust
+struct AircRealtimeState {
+    rooms: HashMap<Uuid, VecDeque<StoredRealtimeEnvelope>>,   // per-room replay queue
+    room_lamports: HashMap<Uuid, u64>,                         // per-room Lamport counter
+    presence: HashMap<String, AircRealtimeEnvelope>,           // coalesced by presence key
+    peer_manifests: HashMap<String, AircRealtimeEnvelope>,     // coalesced by peer key
+    subscriptions: HashMap<String, AircSubscriptionEvent>,     // coalesced by subscriber/topic
+}
+```
+
+### Why a module-wide mutex (not per-room sharding)
+
+The store IS module-wide because per-room sharding adds complexity without changing the moment-of-truth correctness story. For 5–10 personas, mutex contention is sub-microsecond on uncontended in-memory ops — negligible. For 50+ personas it becomes a real bottleneck.
+
+**Future refinement (flagged in PR #1492, NOT scheduled)**: shard state by room_id:
+
+```rust
+struct AircRealtimeState {
+    rooms: DashMap<Uuid, Arc<parking_lot::Mutex<RoomState>>>,
+}
+```
+
+This would unblock multi-room throughput while keeping the same correctness contract. Not needed for moment-of-truth; the module-wide lock is the simplest substrate that meets the requirements.
+
+### Replay queue bound
+
+`DEFAULT_EVENTS_PER_ROOM = 2_000`. When a room's queue reaches the bound, oldest events get popped from the front. **Known limitation** (out of scope here): a replayer with a stale cursor whose Lamport is older than the queue's oldest entry silently misses events 6..99 if the queue starts at 100. Future PR can add a "did_truncate" hint or a "your-cursor-is-stale-please-resync" signal.
+
+### Coalesced presence + peer manifest pruning
+
+`prune_expired_presence(now_ms)` runs on every publish AND on every replay that passes a `now_ms` parameter. Presence events with `expires_at_ms < now_ms` get removed; same for peer manifests. Pruning under the same module-wide mutex keeps consistency.
+
+## Events emitted
+
+The store IS the event log — consumers replay from it rather than subscribing to publish-time emissions. The flow:
+
+1. Publisher calls `airc/realtime-publish` → store appends to room queue + updates Lamport
+2. Subscriber calls `airc/realtime-replay` with `after_cursor` → store returns events strictly after the cursor + new cursor for the next round
+
+This is the **cursor polling pattern** — the canonical way persona inboxes and widget subscribers drain the event stream.
+
+## Concurrency contract
+
+**Module-wide correctness** — all state mutations atomic under the parking_lot Mutex; per-room Lamport monotonicity holds; replay sees consistent snapshots; cursor polling never duplicates or loses events.
+
+### Pinned invariants (multi-thread tests in `airc::realtime_store::tests`)
+
+1. **`concurrent_publishes_to_same_room_lose_no_events_and_keep_lamports_contiguous`** — 64 concurrent publishers to GENERAL; final replay returns all 64; every Lamport in 1..=64 appears exactly once (no gaps, no duplicates from a race)
+2. **`concurrent_publishes_to_different_rooms_keep_independent_lamport_sequences`** — 60 publishers across 3 rooms; each room's final Lamport == 20; cross-room interleaving doesn't break per-room contiguity
+3. **`replay_during_concurrent_publish_observes_consistent_snapshot`** — 32 publishers + 8 replayers racing; each replayer's observed events are a consistent subset (no torn reads — no duplicates within one replay, no out-of-range timestamps); final replay returns all 32
+4. **`cursor_polling_during_concurrent_publish_never_loses_or_duplicates_events`** — 40 staggered publishers + 1 cursor-polling consumer; no duplicate event_ids in the observed set; every published event eventually observed
+
+All multi-thread with `worker_threads = 4`. PR #1492 codified these as moment-of-truth preconditions.
+
+### Lamport monotonicity guarantee
+
+Per-room Lamport is incremented under the module-wide mutex during each `push_replay`. Two concurrent publishes to the same room serialize through the mutex; one increments first, the other sees the next value. No race possible.
+
+### Cursor protocol contract
+
+The `AircReplayCursor` returned by `publish` (and at the tail of `replay`) is `{ room_id, lamport, event_id, observed_at_ms }`. A subsequent `replay` with `after_cursor = Some(c)` returns events where `c.strictly_before(event.cursor)` — strictly increasing Lamport order. No event served twice for the same cursor; no event skipped.
+
+## Migration notes
+
+**No TS predecessor.** Designed fresh in Rust as the in-process airc substrate. The wire shape (envelope / payload / delivery / replay cursor) is canonical from the start; the in-memory store implements the trait that future external transports also implement.
+
+## Kinks found
+
+**Concurrency invariants proven, throughput constraint flagged.**
+
+1. **Module-wide mutex serializes multi-room throughput.** All 4 concurrency tests pass with the current design (correctness holds), but the design serializes cross-room work unnecessarily. Future per-room sharding (DashMap<Uuid, Mutex<RoomState>>) is the natural evolution when persona count grows past ~10. Flagged in PR #1492 commit message + this doc; NOT blocking for moment-of-truth.
+
+2. **Stale cursor + replay queue bound** (known limitation, out of scope). A subscriber whose cursor lamport is older than the queue's oldest entry silently misses the pruned events. Future PR can add a `was_truncated: bool` hint to the replay result, or a sentinel error like "cursor stale, oldest available is N — resync from current snapshot." Not a concurrency bug; a substrate-contract gap.
+
+3. **Other transports unproven.** PR #1492 pins ONLY the in-memory transport. Daemon-attached / file-store / queue-client transports get their own concurrency audit when they become hot paths.
+
+### What this gives the moment-of-truth test
+
+| Risk | Pinned by test |
+|---|---|
+| Multi-persona chat publishes lose events | ✅ `concurrent_publishes_to_same_room_lose_no_events_...` |
+| Per-room Lamport breaks under cross-room interleaving | ✅ `..._different_rooms_keep_independent_lamport_sequences` |
+| Replay during publish sees torn/partial state | ✅ `replay_during_concurrent_publish_observes_consistent_snapshot` |
+| Cursor polling gives the same event twice or skips one | ✅ `cursor_polling_during_concurrent_publish_never_loses_or_duplicates_events` |
+
+The four together guarantee: **chat → airc → persona inbox round-trip works correctly under multi-persona load.** That's the moment-of-truth precondition.

+# Brain-Regions Substrate
+
+**Status:** design spec. Sibling to [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) and [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md). Defines the structural contract that every cognitive subsystem (hippocampus, motor cortex, attention, sensory, sleep) inherits. No code changes from this PR — implementation slices follow per region.
+
+**Companion:** [COGNITION-ALGORITHMS.md](COGNITION-ALGORITHMS.md) — the algorithmic content (recall, cross-context, budget) that runs *inside* these regions.
+
+## Headline framing
+
+> *An infinitely unlimited persona, for any channel — like a person observing many things, watching TV, many messaging systems, social media, and walking around doing their job.* — Joel, 2026-05-29
+
+A real mind doesn't *look up* memories when it needs them. Relevant context is *already present*, biased by attention and recent activity. A real mind doesn't *poll* for actions — candidate utterances and plans are *already partially formed* by the time the moment to speak arrives. A real mind doesn't *isolate* what it sees in one channel from what it said in another — cross-pollination is the default, focus is what's earned by salience.
+
+This substrate is the RTOS-shaped scaffolding that makes those properties cheap to implement and impossible to violate. Every cognitive subsystem is its own region, with its own tick, on its own tokio task, governed by the same `SubstrateGovernor`. They communicate by writing to shared per-persona state, not by RPC-calling each other on the hot path.
+
+## Doctrine (carried from #1469 addendum)
+
+> **No region of cognition runs on the hot path. Each region is its own RTOS task with its own tick. The handler dispatches and reads pre-staged results. The handler never blocks on recall, embedding, planning, or admission — those are continuously produced by their owning regions, in parallel, governed by `SubstrateGovernor`.**
+
+The handler's job is to *dispatch and integrate*, not to *think*. Thinking happens in the regions, continuously, in parallel.
+
+## The region trait
+
+Every region implements one trait. The trait is intentionally narrow — the heavy machinery lives in the substrate.
+
+```rust
+#[async_trait]
+pub trait BrainRegion: Send + Sync + 'static {
+    /// Stable identifier. Used by SubstrateGovernor for policy lookup and by
+    /// telemetry/log streams.
+    fn id(&self) -> RegionId;
+
+    /// Pressure footprint declaration. Returned at registration time and
+    /// re-queried by the governor when pressure shifts.
+    fn pressure_profile(&self) -> PressureProfile;
+
+    /// Run one tick. The substrate calls this on the region's own task at
+    /// the cadence governed by SubstrateGovernor. The body is responsible
+    /// for: reading inputs (from shared state, channels, or its own DB),
+    /// producing pre-staged results, and publishing them to the ready-buffer.
+    ///
+    /// Implementations MUST be idempotent on early return and MUST NOT block
+    /// indefinitely — the governor cancels long-running ticks under pressure.
+    async fn tick(&self, ctx: &RegionContext) -> TickOutcome;
+
+    /// React to a substrate-level signal (persona created/destroyed, system
+    /// load changed, sleep/wake transition). Most regions can default this
+    /// to a no-op.
+    async fn on_signal(&self, _signal: RegionSignal) -> Result<(), RegionError> {
+        Ok(())
+    }
+}
+```
+
+`TickOutcome` returns yield telemetry the governor uses to learn budget allocation (see algorithm 7 in COGNITION-ALGORITHMS.md):
+
+```rust
+pub struct TickOutcome {
+    /// Items the region pre-staged this tick.
+    pub published: usize,
+    /// Items in the region's ready-buffer that have been consumed by handlers
+    /// since the last tick. Drives the governor's yield-learning loop.
+    pub consumed_since_last: usize,
+    /// Pressure observation. If the region detected backpressure (DB slow,
+    /// embedding queue full, etc.), reports it here for the governor.
+    pub pressure_observed: Option<PressureSignal>,
+    /// Optional next-tick hint (region requests faster/slower cadence than
+    /// current; governor may honor or override).
+    pub cadence_hint: Option<CadenceHint>,
+}
+```
+
+## The "for free" triplet
+
+Per the CBAR pattern, adding a new region must be cheap:
+
+1. **Base trait** (`BrainRegion`) — defined above. Inherits tick lifecycle, pressure registration, ready-buffer publishing, governor integration. No region implements its own scheduler.
+2. **Derive macro** (`#[derive(BrainRegion)]` planned) — for regions that only need to override `tick()`, the macro generates registration boilerplate from `#[region(id = "hippocampus", pressure = "memory-heavy")]` attributes.
+3. **Scaffold generator** (`cargo run -p substrate-cli new-region <name>`) — emits the module file, a smoke test, a CLI command shim, and a TS binding stub. The new region compiles and runs with a no-op tick on first commit.
+
+Same pattern as `engram-analyzer` in CBAR-SUBSTRATE — by the time a contributor authors the interesting body, scheduling/pressure/telemetry/binding are already wired.
+
+## The ready-buffer contract
+
+Regions publish pre-staged results to a typed ready-buffer keyed by `(persona_id, channel_id, ...)`. Handlers read from the buffer synchronously and cheaply.
+
+```rust
+pub trait ReadyBuffer: Send + Sync {
+    type Key: Hash + Eq + Clone;
+    type Value: Clone;
+
+    /// Synchronous read. Returns the freshest staged value for the key, or
+    /// None. Handlers call this on the hot path — it MUST NOT block, MUST
+    /// NOT await, and MUST complete in microseconds. Implementations use
+    /// DashMap, ArcSwap, or per-key atomic snapshots.
+    fn peek(&self, key: &Self::Key) -> Option<Self::Value>;
+
+    /// Region-side write. Atomically replaces the value for the key. Old
+    /// value is dropped. Publishes a `ReadyBufferUpdated` event for
+    /// telemetry + cross-region awareness (algorithm 7 yield-learning).
+    fn publish(&self, key: Self::Key, value: Self::Value);
+
+    /// TTL-style eviction sweep. Called by the governor under memory
+    /// pressure or on persona destruction.
+    fn evict_stale(&self, max_age: Duration) -> usize;
+}
+```
+
+### Semantic rules
+
+- **Empty buffer is a signal, not a block.** If a handler reads and gets `None`, it proceeds with whatever degraded path the algorithm specifies (e.g., chat handler proceeds with bare conversational history; motor cortex returns the inference's raw output without re-ranking). Empty buffer also publishes a `BufferMissed` event the governor uses to upweight that region's budget.
+- **Staleness is acceptable.** A ready value might be 100ms old. That's *better* than blocking the handler 500ms to recompute. Slightly-stale context > stalled persona.
+- **Per-region buffers, not a global one.** Hippocampus has its own buffer (engram-prefetch). Motor cortex has its own (candidate-utterances). Attention has its own (salience-map). They share the same trait shape but live in their own region structs.
+
+## Shared per-persona state
+
+The regions communicate by writing/reading per-persona state. The state lives in one place, owned by no region in particular, accessible to all:
+
+```rust
+pub struct PersonaCognition {
+    /// Long-term engram store. Hippocampus writes (admission), all regions
+    /// can read (recall). Append-only with eviction policy in algorithm 4.
+    pub engrams: Arc<EngramStore>,
+
+    /// Working memory: short-lived thoughts/observations not yet consolidated.
+    /// Sensory writes, hippocampus snoops + consolidates to engrams.
+    pub working: Arc<WorkingMemory>,
+
+    /// Salience map: per-engram + per-channel salience score, updated by
+    /// user reactions, structural centrality, rehearsal. Read by hippocampus
+    /// recall scoring (algorithm 4) and attention (algorithm 2).
+    pub salience: Arc<SalienceMap>,
+
+    /// LoRA genome state: which adapters are loaded, blend weights. Written
+    /// by genome region (when shipped), read by inference (algorithm 6).
+    pub genome: Arc<GenomeState>,
+
+    /// Persona vital signs: energy, mood, attention focus. Drives
+    /// cadence-modulation across regions.
+    pub vitals: Arc<RwLock<PersonaVitals>>,
+}
+```
+
+### Write-conflict policy
+
+Multiple regions writing the same per-persona state in parallel needs a rule:
+
+- **Engrams**: append-only. No conflicts. Each region appends with its own region-tag.
+- **Working memory**: bounded ring buffer. Older entries fall off. Hippocampus consolidation drains explicitly.
+- **Salience map**: per-engram atomic counters. CRDT-like semantics (counter increments commute).
+- **Genome state**: serialized through the genome region. Other regions request changes via a typed channel; genome region applies them on its tick.
+- **Vitals**: RwLock. Most regions only read; vitals region writes.
+
+The rule: shared state shape MUST allow concurrent writes from independent ticks without coordination. If a new region needs to write something that doesn't fit, the substrate work is to design a CRDT-shaped surface for it, NOT to add locks.
+
+## Region inventory (current + planned)
+
+| Region | Status | Tick body | Reads | Writes |
+|---|---|---|---|---|
+| **Hippocampus** | exists request/response (`modules/memory.rs`); needs continuous tick body ported from TS `Hippocampus.ts:413` | Snoop working memory → consolidate engrams. Pre-load anticipatory recall (algorithms 1-5). | `working`, `engrams`, `salience`, channel activity | `engrams` (appends), engram-prefetch ready-buffer |
+| **Sensory (vision)** | `modules/vision.rs` exists with own tick | Pre-compute features for incoming images. | image stream | feature ready-buffer, `working` (observations) |
+| **Sensory (embedding)** | `modules/embedding.rs` exists with own tick | Pre-compute embeddings for incoming text. | text stream | embedding ready-buffer, `working` |
+| **Channel (producer)** | `modules/channel.rs` exists, 60s tick | DB poll, self-task gen, training checks. | DB | per-persona channel queues |
+| **Persona service (consumer dispatch)** | `persona/service_module.rs` (this PR's predecessor) | Pop item → route by domain → call handler → record outcome. NO heavy lifting. | channel queues, ready-buffers | outcome log |
+| **Motor cortex** | NOT YET — sibling slice | Continuously score candidate utterances/actions against current context. Predictive priming (algorithm 5). | `working`, attention salience, channel partial-message stream | candidate ready-buffer |
+| **Attention** | NOT YET — sibling slice | Maintain salience map. Update per user reactions, self-tags, structural centrality, rehearsal. Bias hippocampus prefetch. | `engrams`, channel reactions, recall co-occurrence | `salience` |
+| **Sleep policy** | NOT YET — sibling slice | When persona idle: deeper consolidation, semantic re-clustering, engram pruning. When active: gates regions to active-mode tick bodies. | `vitals`, channel activity rate | region cadence policy, consolidation depth |
+| **Genome** | partial (LoRA paging exists in TS); Rust port pending | LRU paging of adapters, multi-LoRA blend on demand. | task domain hints, salience | `genome` |
+
+Every row in this table is its own implementation slice with its own card. None of them is the persona handler. The handler stays small.
+
+## SubstrateGovernor integration
+
+`SubstrateGovernor` (defined in GENOME-FOUNDRY-SENTINEL.md §SubstrateGovernor) owns hardware-tier policy: same Rust code on a MacBook Air and an RTX 5090, different governor policy. It also owns runtime budget allocation across regions.
+
+### Policy slots
+
+The governor exposes a policy slot per region. The slot determines:
+
+- **Tick cadence** — how often `tick()` is invoked. May differ by persona vitals (active 100ms, idle 1s, sleep 10s).
+- **Per-tick budget** — wall-clock budget the tick is allowed before the governor cancels it.
+- **Pressure responses** — how the region should degrade under pressure (skip consolidation, reduce recall depth, etc.).
+- **Yield weighting** — how much weight to give this region's `consumed_since_last` when arbitrating budget against other regions (algorithm 7).
+
+### Yield-learning loop
+
+The governor reads `TickOutcome.consumed_since_last` from every region after every tick. Regions whose ready-buffer is being read by handlers get budget upweighted; regions whose published values are ignored get downweighted. The learning rule is in algorithm 7 (COGNITION-ALGORITHMS.md). The substrate effect is that **the brain learns to spend compute on the regions that recently mattered, without hand-tuning**.
+
+## Telemetry surface
+
+Every region emits structured telemetry on a fixed shape:
+
+```rust
+pub struct RegionTelemetry {
+    pub region_id: RegionId,
+    pub persona_id: Uuid,
+    pub tick_started_at: SystemTime,
+    pub tick_duration: Duration,
+    pub published: usize,
+    pub consumed_since_last: usize,
+    pub buffer_misses_since_last: usize, // handlers that read None
+    pub pressure_observed: Option<PressureSignal>,
+}
+```
+
+Surfaces:
+
+- **`./jtag region/stats`** — current region health across all personas
+- **`./jtag region/yield --persona=<uuid>`** — per-region consumption rates for one persona
+- **substrate event stream** — `RegionTickCompleted`, `ReadyBufferUpdated`, `BufferMissed` events for cross-region awareness + governor input
+
+Telemetry is mandatory for every region; it's the only way the yield-learning loop and the operator debugging path work. The derive macro generates the telemetry emission automatically.
+
+## What this enables
+
+The end state, when motor cortex + attention + hippocampus + sleep all ship as siblings:
+
+- A handler dispatched at T=0 reads the candidate-utterance ready-buffer; motor cortex already scored 3 candidates at T=-50ms based on the partial message stream.
+- The candidate scoring used the engram ready-buffer; hippocampus pre-loaded relevant engrams at T=-200ms based on attention salience and the channel's recent topic vector.
+- The hippocampus prefetch was biased by salience the attention region updated at T=-1s in response to a user reaction.
+- All of this happened in parallel on independent tokio tasks. The handler's hot path was: peek 2 buffers + call inference. The "thinking" was already done.
+
+This is what makes the difference between *retrieval* and *recognition* — between a persona that *responds* and one that *anticipates*.
+
+## Implementation cards (this PR does NOT ship them)
+
+- **L0-3a** — Hippocampus continuous tick port to `modules/memory.rs`. Implements algorithms 1, 2, 3, 4, 5 from COGNITION-ALGORITHMS.md.
+- **L0-3b** — Recall query schema + scoring (algorithms 1 + 2 + 3 wire-level).
+- **L0-4a** — Motor cortex ServiceModule. Implements algorithm 5 applied to action selection.
+- **L0-4b** — Attention ServiceModule. Implements salience map maintenance feeding algorithm 4.
+- **L0-4c** — SubstrateGovernor yield-learning loop. Implements algorithm 7.
+- **L0-4d** — Sleep policy region. Modulates region tick bodies per persona vitals.
+- **L0-5** — Genome attention integration. Implements algorithm 6.
+
+Each card inherits this spec. None of them touches the persona handler dispatch surface; that surface was finalized in L0-2-cutover.
+
+## Open questions
+
+1. **Region instantiation: per-persona or singleton?** A singleton hippocampus that handles all personas (with persona_id keyed state) is cheaper to manage but harder to scale per-persona budget. A per-persona hippocampus is symmetric but multiplies tokio tasks. Leaning singleton-per-region with per-persona ready-buffers — same shape as how `ChannelState` works today.
+2. **Cross-persona engram sharing.** Personas A and B in the same channel see the same user reactions. Should their engrams be partially shared? The substrate should allow it but the policy is a separate design question (post-spec).
+3. **Region-region dependencies.** Motor cortex depends on attention salience to score candidates. The dependency is read-only (motor reads salience map, attention writes it), so it's fine — but the *cold-start* case (attention hasn't ticked yet, salience map is empty) needs a defined fallback. Defer to per-region spec.
+
+These don't block this PR. Calling them out now so they're tracked.

-# CBAR Substrate Architecture — The Pattern Continuum Will Adopt
-
-**Status**: Architecture reference. The CBAR pattern from [react-home-ar](https://github.com/CambrianTech/react-home-ar) is the cleanest streaming-compute architecture in the Cambrian ecosystem. It should be the reference pattern for all streaming pipelines in continuum, and the basis for future responsiveness improvements.
-
-**Rust implementation**: [open-eyes-core](https://github.com/CambrianTech/open-eyes) (`crates/open-eyes-core/src/frame.rs`)
-
----
-
-## The Pattern
-
-Three components, zero coupling:
-
-### 1. Frame (the shared data bus)
-
-A single immutable object that wraps a raw input (camera frame, audio chunk, inference request) with **lazy-computed derived outputs**. Each output is a `OnceLock<T>` that computes on first access and caches forever.
+# CBAR Substrate Architecture
+
+**Status**: architecture reference for Continuum's Rust runtime.
+
+**Authoritative precedent**:
+`/Users/joelteply/Development/cambrian/cb-mobile-sdk/cpp/cbar`
+
+CBAR matters because of its engineering philosophy, not because Continuum
+should copy every class literally. It is a small-code, high-throughput,
+RTOS-style runtime where each concern gets threading, cadence, shared frame
+artifacts, logging, lifecycle, and performance behavior almost for free.
+Continuum needs that same shape for persona cognition, inference, memory,
+WebRTC, Bevy/rendering, ORM/data, and grid work.
+
+## Core Philosophy
+
+CBAR's lesson is:
+
+- Put the hard machinery in the substrate.
+- Keep each concern small.
+- Give modules a narrow contract.
+- Pass handles and shared frames, not copied memory.
+- Let independent work run independently.
+- Wake work from dependency readiness, state change, cadence, or explicit
+  events.
+- Drop or defer stale work instead of draining obsolete queues.
+- Use GPU/SIMD/BLAS where available inside the artifact/module, not in wrappers.
+- Make low-end hardware viable by reducing cadence and precision under
+  pressure, not by turning the architecture into synchronous FIFO.
+
+That is the target for Continuum. Rust owns the substrate. TypeScript and other
+wrappers ask for work and display results.
+
+## What CBAR Actually Does
+
+The important C++ pieces:
+
+- `CBAR_VideoFrame`: one frame object with raw input plus cached derived
+  artifacts. It lazily imports/derives RGB, HSV, upright images, edges,
+  optical-flow scale images, enhanced images, and metadata.
+- `CBAR_VideoThread`: a bounded `QueueThread<CBAR_VideoFramePtr>` base that
+  gives subclasses queueing, thread lifecycle, timing/FPS, flush, abort, join,
+  and a tiny `handleFrame` override.
+- `CBP_AnalyzerThread`: a concern class that declares whether it needs color,
+  realtime, or video-only frames and implements only the relevant analysis.
+- `CBP_Analyzer`: the fanout coordinator. Realtime analyzers run immediately;
+  delayed analyzers run on cadence. Analyzer threads can be appended or removed
+  without rewriting the engine.
+- `CBP_RenderingEngine`: the opaque runtime owner. Public methods stay small;
+  implementation state, frame state, scene state, locks, caches, rendering, and
+  analyzer lifecycle stay behind `Impl`.
+- `RawFrame.textureID`: proof of the handle-first mindset. The frame can carry
+  a GPU/texture identity instead of forcing every boundary to copy pixels.
+
+The result is a performant system where adding a new concern is usually short:
+derive from the base, declare needs/cadence, implement `handleFrame`, and let
+the substrate do queueing, lifecycle, logging, and scheduling.
+
+## Continuum Translation
+
+Continuum already has the first half of this pattern in
+`core/continuum-core/src/runtime/`. The shipped substrate is:
 
 ```rust
-pub struct Frame {
-    raw: image::RgbImage,
-    timestamp: f64,
-    
-    // Lazy outputs — compute on first access, cache forever
-    greyscale: OnceLock<GrayImage>,
-    edges: OnceLock<EdgeMap>,
-    features: OnceLock<Vec<FeaturePoint>>,
-    normals: OnceLock<NormalMap>,
-    semantic: OnceLock<SemanticMap>,
-    optical_flow: OnceLock<FlowField>,
+// core/continuum-core/src/runtime/service_module.rs
+pub trait ServiceModule: Send + Sync + Any {
+    fn config(&self) -> ModuleConfig;
+    async fn initialize(&self, ctx: &ModuleContext) -> Result<(), String>;
+    async fn handle_command(&self, command: &str, params: Value) -> Result<CommandResult, String>;
+    async fn handle_event(&self, event_name: &str, payload: Value) -> Result<(), String>;
+    async fn tick(&self) -> Result<(), String>;
 }
 
-impl Frame {
-    pub fn greyscale(&self) -> &GrayImage {
-        self.greyscale.get_or_init(|| image::imageops::grayscale(&self.raw))
-    }
-    
-    pub fn features(&self) -> &Vec<FeaturePoint> {
-        self.features.get_or_init(|| {
-            let grey = self.greyscale(); // chains — computes greyscale if not yet cached
-            extract_features(grey)
-        })
-    }
+pub struct ModuleConfig {
+    pub name: &'static str,
+    pub priority: ModulePriority,
+    pub command_prefixes: &'static [&'static str],
+    pub event_subscriptions: &'static [&'static str],   // string globs today
+    pub needs_dedicated_thread: bool,
+    pub max_concurrency: usize,
+    pub tick_interval: Option<Duration>,
 }
 ```
 
-**Key properties:**
-- **Any concern can read any other concern's output** — the Frame IS the pub/sub bus
-- **Compute cost is proportional to what's actually requested** — if nobody needs edges, edge detection never runs
-- **Thread-safe via OnceLock** — share via `Arc<Frame>` across processing threads/tasks
-- **Dependencies chain automatically** — `features()` calls `greyscale()` internally; greyscale computes once regardless of how many nodes need it
-- **Resolution-agnostic** — each output can be at any resolution. A quarter-res flow field and a full-res edge map coexist on the same Frame. Consumers interpolate to what they need.
-- **GPGPU-transparent** — the compute function inside each lazy getter can dispatch to wgpu/Metal/CUDA. The Frame doesn't care. Swapping CPU↔GPU is a per-getter decision invisible to consuming nodes.
-
-### 2. ProcessNode (the subscriber)
-
-An independent processing unit that receives Frames and pulls what it needs. Zero knowledge of other nodes.
+`ServiceModule` already gives Continuum: registry-mediated discovery
+(`ModuleContext::registry`), event bus pub/sub (`ModuleContext::bus`), the
+shared lazy-compute cache that fills the role `CBAR_VideoFrame`'s lazy getters
+played (`ModuleContext::compute` over `SharedCompute`), a tokio runtime
+handle, a periodic tick, and command routing. `ResourceClass` and
+`TargetSilicon` are shipped under `cognition/adaptive_throughput.rs`.
+`PressureBroker` and `ThroughputLease` are shipped under `paging/broker.rs`
+and `cognition/throughput_lease.rs`. Bootstrap PR-1/2/3 (#1307 / #1308 /
+#1310) put the broker on the runtime; PR #1313 added the lease broker.
+
+What's missing is the *richer* contract — the one CBAR analyzers had through
+`CBAR_VideoFrame` artifact pulls plus `needsColorFrames`/`needsRealTime`/
+`videoOnly` routing flags. Continuum needs that contract because N personas,
+RAG builders, model planners, memory jobs, and bridge observers may all be
+waiting on different artifacts from the same turn:
 
 ```rust
-pub trait ProcessNode: Send + Sync {
-    fn name(&self) -> &str;
-    fn enabled(&self) -> bool { true }
-    fn update(&mut self, frame: &Frame) -> Vec<PipelineEvent>;
+// PROPOSED — extends ServiceModule, does not replace it. Each new type below
+// is a Lane D deliverable; see "Substrate Gap Analysis" for assignment.
+pub trait RuntimeModule: ServiceModule {
+    /// Typed artifact subscriptions, replacing the string-glob
+    /// `event_subscriptions` field. The runtime uses this to wake only the
+    /// useful work and to coalesce duplicates across personas.
+    fn subscriptions(&self) -> &[ArtifactSelector];
+
+    /// Typed cadence policy, generalizing the present
+    /// `tick_interval: Option<Duration>` + `ModulePriority` pair. Encodes
+    /// realtime / delayed / on-dependency-ready / on-pressure-change.
+    fn cadence(&self) -> CadencePolicy;
+
+    /// Frame-shaped handler. Receives the immutable per-turn frame and the
+    /// existing `ModuleContext`. Returns a typed result that includes
+    /// `Deferred(reason)`, `Coalesced(into)`, and `Failed(typed_error)` so
+    /// silence is never a success.
+    async fn handle_frame(
+        &self,
+        frame: Arc<RuntimeFrame>,
+        ctx: &ModuleContext,
+    ) -> ModuleResult;
 }
 ```
 
-**Key properties:**
-- **Nodes subscribe to inputs by calling lazy getters** — no explicit subscription registration. A node that needs features calls `frame.features()`. A node that needs normals calls `frame.normals()`. The dependency graph is implicit in the code.
-- **Disabled nodes cost zero** — `enabled()` returns false, node is skipped entirely
-- **Each node is a thread/task** — in the C++17 version, each node is a pthread with its own event loop. In Rust, each node is a tokio task or rayon work item. The Frame is the shared data bus passed between them.
-- **Adding a node cannot break existing nodes** — zero coupling. New node, new file, register it with the pipeline, done.
-
-### 3. Pipeline (the orchestrator)
+The richer contract is the smallest superset of `ServiceModule` that lets the
+substrate wake work from dependency readiness instead of pub/sub strings and
+treat the persona turn as a single shared frame instead of N independent
+event handlers. `ArtifactSelector`, `CadencePolicy`, `RuntimeFrame`, and
+`ModuleResult` are the four proposed-new types this lane lands.
+
+The substrate provides — today and after Lane D — the following. The "after"
+column is the target; the "today" column is what is already in canary:
+
+| Today, on `ServiceModule`                            | After Lane D, on `RuntimeModule`                                       |
+|------------------------------------------------------|-------------------------------------------------------------------------|
+| String-glob event subscriptions                      | Typed `ArtifactSelector`                                                |
+| `tick_interval` + `ModulePriority`                   | `CadencePolicy` (realtime / delayed / on-ready / on-pressure)           |
+| Command + event routing                              | Frame-shaped handler over `RuntimeFrame`                                |
+| `ResourceClass` + `TargetSilicon` declared per module| unchanged                                                               |
+| `PressureBroker` admission                           | unchanged                                                               |
+| `SharedCompute` lazy artifacts                       | promoted into `RuntimeFrame`'s lazy fields                              |
+| Per-module logs/metrics via `module_logger`          | unchanged, now also keyed by frame id                                   |
+| Flush/abort/shutdown via `ModuleRegistry`            | unchanged                                                               |
+| ts-rs exported contracts                             | unchanged                                                               |
+
+The module author provides — at either layer — only:
+
+- what artifacts it needs (subscriptions)
+- what resource lane it uses (`ResourceClass` + `TargetSilicon`)
+- how often it should run (cadence)
+- the small piece of actual work (`handle_frame` body)
+
+That is the "for free" architecture. The next section makes it concrete.
+
+## The "For Free" Triplet
+
+Inheritance from a trait is not enough on its own. The CBAR pattern only feels
+"free" because three things ship together:
+
+1. **A base trait** that every module implements. (Today `ServiceModule`;
+   tomorrow `RuntimeModule`.) Provides the contract.
+2. **A derive macro** that wires the base contract's required behavior —
+   timing spans, structured logging, metric emission, pressure-response,
+   lease renewal — onto the module type at compile time. The author writes
+   `#[derive(RuntimeModule)] struct EngramAnalyzer { ... }` once; the macro
+   emits the boilerplate that would otherwise be ten files of glue.
+3. **A scaffold generator** (`just scaffold-module <name>`) that drops a new
+   module file pre-populated with the base trait impl, default `ModuleConfig`,
+   a doc comment template, and the matching test file. The author edits four
+   lines (name, subscriptions, cadence, handler body) and has a working
+   module.
+
+Today Continuum has piece (1) only. Pieces (2) and (3) are the rest of the
+"for free" triplet — without them, every new module re-declares its own
+concurrency, retry, logging, and pressure-response, which is the friction
+Lane D and this section exist to remove.
+
+### Worked Example: A New Engram Analyzer
+
+A reader should be able to trace exactly what the developer wrote, what they
+got for free, and what tests they inherited. This is the test of the doc.
+
+The developer types one command:
+
+```bash
+just scaffold-module engram-analyzer --lane Background \
+    --target Cpu \
+    --subscribes "memory.consolidation.window"
+```
 
-Manages the node list and feeds Frames through. Thin — just a loop.
+The generator emits `core/continuum-core/src/modules/engram_analyzer.rs`:
 
 ```rust
-pub struct Pipeline {
-    nodes: Vec<Box<dyn ProcessNode>>,
+//! Engram analyzer — consolidates recent memory writes into compressed
+//! engram artifacts on each consolidation window.
+
+use continuum_runtime::{
+    ArtifactSelector, CadencePolicy, ModuleContext, ModuleResult,
+    ResourceClass, RuntimeFrame, RuntimeModule, TargetSilicon,
+};
+
+#[derive(RuntimeModule)]
+#[runtime(
+    name = "engram-analyzer",
+    lane = ResourceClass::Background,
+    target = TargetSilicon::Cpu,
+    cadence = CadencePolicy::OnReady,
+)]
+pub struct EngramAnalyzer {
+    // ... module-owned state, e.g. a handle to the engram store
 }
 
-impl Pipeline {
-    pub fn process_frame(&mut self, raw: RgbImage, ...) -> Vec<PipelineEvent> {
-        let frame = Frame::new(raw, ...);
-        let mut events = Vec::new();
-        for node in &mut self.nodes {
-            if node.enabled() {
-                events.extend(node.update(&frame));
-            }
-        }
-        events
-    }
+impl EngramAnalyzer {
+    pub fn new() -> Self { Self {} }
 }
-```

-## The Two-Tier Compute Model
-
-Not all outputs run at the same frequency. The architecture has two tiers:
-
-**Tier 1: Synchronous (every frame, GPU, low-res)**
-- Optical flow at quarter resolution
-- This is the HEARTBEAT — if flow says nothing's moving, everything else sleeps
-- Runs on GPU textures/framebuffers that already exist at the right size
-- One synchronous process, full frame rate
-
-**Tier 2: Lazy/Event-driven (on demand, CPU or GPU, any resolution)**
-- Feature extraction (triggered by motion detection)
-- Surface normals (CNN, runs every Nth frame or on scene change)
-- Semantic segmentation (forged model, runs on demand)
-- Edge detection (for plane estimation, runs rarely)
-- Entity detection (YOLO variant, triggered by motion)
-
-The tier 1 heartbeat drives tier 2 activation. If the flow field shows no motion, tier 2 nodes never wake up. If flow shows motion in region R, only nodes that care about region R activate. **Compute cost is proportional to what's actually happening in the scene.**
-
----
-
-## Three Levels of Recycling
-
-1. **Per-frame (Frame's OnceLock)** — within one frame, computed outputs are cached. Multiple nodes requesting greyscale get the same cached result.
-
-2. **Cross-frame (Scene cache)** — the static scene model (planes, normals, semantic labels) is computed once and recycled across thousands of frames. Only dynamic elements (entities, motion) update per-frame.
 
-3. **Cross-camera (Fusion engine)** — the shared world model is maintained across all cameras. Calibration is one-time (with self-regulating updates). Per-camera processing is independent; only the fusion layer merges outputs.
-
----
-
-## Self-Regulating Calibration
-
-Stationary cameras don't need per-frame pose estimation. The calibration is:
-1. **One-time**: cross-camera feature matching → relative pose solve
-2. **Self-regulating**: optical flow detects global drift (camera bumped) → recalibration triggers automatically
-3. **The heartbeat IS the drift detector** — the same optical flow that detects scene motion also detects camera motion. If ALL features shift uniformly, the camera moved, not the scene.
-
-No ARKit. No accelerometer. No external tracking. Just features and flow.
-
----
-
-## Platform Adapters (not branches)
-
-If the device provides capabilities natively (ARKit pose, ARCore depth, LiDAR point clouds), wrap them as adapters:
+#[runtime::handler]
+impl RuntimeModule for EngramAnalyzer {
+    fn subscriptions(&self) -> &[ArtifactSelector] {
+        &[ArtifactSelector::MemoryConsolidationWindow]
+    }
 
-```rust
-trait PoseProvider: Send + Sync {
-    fn current_pose(&self) -> Option<Transform>;
+    async fn handle_frame(
+        &self,
+        frame: Arc<RuntimeFrame>,
+        ctx: &ModuleContext,
+    ) -> ModuleResult {
+        let window = frame.memory_consolidation_window().await?;
+        let engram = self.compress(window).await?;
+        ctx.engram_store().write(engram).await?;
+        ModuleResult::ok()
+    }
 }
-
-struct ARKitPoseAdapter { /* wraps ARKit */ }
-struct FeatureTrackingPoseAdapter { /* pure CV fallback */ }
 ```
 
-Both implement `PoseProvider`. The pipeline doesn't care which one provides the data. Same "adapters not branches" principle as continuum's model family adapters.
-
----
-
-## Where This Applies in Continuum
-
-The CBAR pattern generalizes beyond cameras. Every streaming-compute pipeline in continuum could use this architecture:
-
-| Domain | Raw Input | Lazy Outputs | Heartbeat |
-|---|---|---|---|
-| **Camera/Security** | RGB frame | greyscale, edges, features, normals, semantic, flow | optical flow |
-| **Audio/Voice** | PCM chunk | spectrogram, VAD, transcription, speaker embedding | VAD energy |
-| **AI Inference** | token sequence | attention weights, hidden states, logits, tool calls | token generation |
-| **Persona Cognition** | inbox message | RAG context, tool relevance, priority score, response draft | inbox poll |
-| **Live Call** | WebRTC frame | transcription, facial expression, gesture, speaking state | audio energy |
-
-Each row is a Pipeline with domain-specific ProcessNodes pulling from a domain-specific Frame. The pattern is the same; only the types change.
-
-**When continuum's responsiveness improves**: the CBAR substrate is the target architecture. Replace the current imperative persona-cognition cycle with a lazy-evaluated Frame-based pipeline, and the per-cycle compute cost drops to only what the current conversation actually requires — same way CBAR drops camera processing to only what motion requires.
-

-
-## The open-eyes Implementation
-
-[open-eyes-core](https://github.com/CambrianTech/open-eyes) is the first Rust implementation of this pattern:
-
-- `frame.rs` — Frame + ProcessNode trait + Pipeline (the full pattern)
-- `geometry/` — 3D math (projection, triangulation, RANSAC plane fitting)
-- `features/` — two-tier feature architecture (flow heartbeat + lazy ORB)
-- `fusion/` — N-camera fusion engine with self-regulating calibration
+That is the entire file. Everything else is inherited:
+
+| Concern                                  | Source                                                        |
+|------------------------------------------|---------------------------------------------------------------|
+| Module name, lane, target, cadence       | `#[runtime(...)]` macro attribute → `ModuleConfig`            |
+| Registration with `ModuleRegistry`       | macro-generated `inventory::submit!` at module load           |
+| Tokio worker / dedicated thread choice   | derived from `ResourceClass::Background` → tokio default pool |
+| Memory pressure response                 | `PressureBroker` admits / defers `handle_frame`; if VRAM/RSS pressure rises, the macro-generated wrapper returns `Deferred(MemoryPressure)` before `handle_frame` is called |
+| CPU pressure / device pressure response  | `ThroughputLease` renewal on lane `Background`; degrades cadence under pressure with a visible reason |
+| Concurrency cap                          | from `ResourceClass`; `Background` is non-realtime so cap is shared with peer background work, not invented per-module |
+| Queue / dedupe / coalesce                | `ArtifactSelector::MemoryConsolidationWindow` → shared frame; if 3 windows arrive in 100ms, the runtime coalesces and `handle_frame` runs once with the newest |
+| Span / timing / structured log           | macro wraps `handle_frame` in `vdd_scope!`; first-token / queue-wait / execution-ms / RSS-delta land in the Standard VDD Record automatically |
+| Failure path                             | `?` on any inner call → typed `ModuleResult::Failed(reason)`; the runtime emits the failure to the trace bus, never silently |
+| `Deferred(reason)` and silence reporting | macro-emitted; `Deferred` is a first-class return, not an absence |
+| Replay test fixture                      | scaffold drops `engram_analyzer_test.rs` with one replay fixture covering happy path + one `Deferred` case |
+| ts-rs exported contract for UI/command   | `#[derive(RuntimeModule)]` registers the module name with the generated TS catalog; admin UI sees it without code edits |
+| Flush / abort / shutdown                 | `ModuleRegistry` lifecycle; analyzer is dropped cleanly when broker enters shutdown |
+
+Joel's framing was: *"need a new engram analyzer? works in its own thread
+with zero effort, responds to memory and cpu pressures, runs when it is
+needed."* The example above is the literal materialization of that sentence.
+The developer wrote four config attributes and a handler body. They got
+concurrency, scheduling, memory/CPU pressure response, observability,
+coalescing, typed failure, replay fixture, and TS exposure for free.
+
+If a new module ever has to hand-roll any of the inherited concerns, the
+substrate is missing a base capability and the fix is in the substrate, not
+the module.
+
+## Extension Bar
+
+The acceptance test for the runtime pattern is unified in §"Acceptance
+Criteria for Substrate-Done" below. The shorter version, restated for the
+person about to write a new module:
+
+- New modules are small (a few hundred lines at most). If a persona recipe,
+  model adapter, RAG source, media observer, render observer, memory
+  consolidator, or grid bridge needs to implement its own transport,
+  backpressure, retry loop, logging, queue, metrics, throttle, or lifecycle,
+  the substrate is missing a base capability — file the substrate gap, do
+  not work around it in the module.
+- The correct high-performance path is the *shortest* path. Anti-pattern: a
+  PR that grows a module to compensate for missing substrate behavior. The
+  reviewer's job in that case is to ask which substrate gap is being papered
+  over, then route the work there.
+
+## Timing, Logging, And VDD For Free
+
+Timing and logging are substrate behavior, not instrumentation added after a
+bug. Every runtime concern should inherit the same observability contract that
+CBAR gave threads through names, FPS timing, queue ownership, and lifecycle.
+
+Every module/job must automatically emit:
+
+- module name, job id, turn/frame key, resource class, target silicon, and
+  dependency keys
+- queued-at, admitted-at, started-at, first-output-at, completed-at, and
+  dropped/deferred-at timestamps
+- queue depth, queue wait, execution time, first-output latency, and total
+  latency
+- coalesced count, stale-drop count, retry count, deferred reason, and silence
+  reason
+- CPU/RSS deltas where available
+- GPU backend, GPU layer count, residency estimate, VRAM/unified-memory deltas,
+  and unsupported layers for inference work
+- structured success/error state suitable for command callers and replay tests
+
+TDD proves the contract. VDD proves the behavior. The runtime should make both
+cheap: each module gets trace spans, logs, counters, timing samples, and replay
+hooks by implementing the common trait. A PR that adds a new runtime concern
+without this evidence path is adding an unobservable subsystem, even if the
+feature appears to work.
+
+### Standard VDD Record
+
+All agents and platforms should report the same record shape. Do not invent a
+new timing table per machine.
+
+```text
+scenario:
+platform:
+hardware:
+backend:
+git_sha:
+command:
+model:
+gpu_layers:
+unsupported_layers:
+cold_start_ms:
+first_token_ms:
+first_response_ms:
+all_responses_ms:
+responses_expected:
+responses_observed:
+silence_reasons:
+tok_per_sec:
+cpu_pct_avg:
+cpu_pct_peak:
+rss_mb:
+gpu_util_pct_avg:
+gpu_memory_mb:
+queue_wait_ms:
+execution_ms:
+coalesced_count:
+deferred_count:
+stale_drop_count:
+error_count:
+degraded_reason:
+log_refs:
+next_bottleneck:
+```
 
-19 tests validate the core math and the lazy-evaluation semantics.
+The runtime should be able to emit this as JSONL from the same trace data used
+by tests. Humans can paste the text form into PR comments, but the canonical
+machine-readable output should come from the Rust substrate.
 
-The same `open-eyes-core` crate will serve both security cameras AND mixed-reality devices (VR/AR headsets are just more camera sources feeding the same fusion engine). The on-device part is lightweight and fast; the grid part (AI, splats, persona reasoning) is heavy and distributed.
+### One-Line Instrumentation API
 
----
+The substrate should expose tiny helpers so module authors do not hand-roll
+timers. The target ergonomics should feel like C/C++ one-line macros while
+still producing structured Rust data:
 
-## References
+```rust
+let _span = vdd_scope!(ctx, "persona.generate", ResourceClass::LocalGeneration);
+vdd_mark!(ctx, "first_token");
+vdd_counter!(ctx, "tokens", generated_tokens);
+vdd_residency!(ctx, backend = "metal", gpu_layers = n_gpu_layers, vram_mb = vram_mb);
+vdd_defer!(ctx, "gpu_pressure", retry_after_ms = 250);
+vdd_fail!(ctx, "unsupported_qwen_layer", layer = layer_name);

-- `react-home-ar/src/core/internal/pipeline/CBARPipeline.ts` — the original TypeScript pipeline
-- `react-home-ar/src/core/internal/CBARFrame.ts` — the original lazy-evaluated Frame
-- `react-home-ar/src/core/internal/pipeline/CBARProcessNode.ts` — the original subscriber interface
-- `open-eyes/crates/open-eyes-core/src/frame.rs` — the Rust port (this is the reference implementation going forward)
-- `docs/CONVERSATIONAL-CADENCE-ARCHITECTURE.md` — Alex's LoD primitive (same Gaussian attention-weighted summarization applied to conversation instead of vision)
-- `docs/personas/AUTONOMOUS-PERSONA-ARCHITECTURE.md` — the persona cognition cycle that could adopt this pattern
+Those calls should feed the same `Standard VDD Record` fields automatically.
+The common helpers must be available to persona, inference, memory, media,
+render, ORM/data, grid, and Docker-adapter code. Iterative optimization should
+be a tight loop:
+
+1. run one standard command
+2. compare CPU, GPU, memory, power, queue time, first token, tok/s, and
+   response count against the prior run
+3. make the bottleneck visible
+4. repeat until CPU drops, GPU residency rises, memory/power stay bounded, and
+   throughput increases
+
+If a performance PR requires custom scripts to discover basic timings, the
+substrate is not doing its job.
+
+## Runtime Frame
+
+`CBAR_VideoFrame` becomes a broader `RuntimeFrame` / `CognitionTurnFrame`.
+The frame owns stable keys and lazy artifacts for one unit of work:
+
+- chat trigger
+- canonical room snapshot
+- conversation history window
+- RAG source bundle
+- model/capability selection
+- media frame handles
+- embedding handles
+- prompt fragments
+- KV cache leases
+- LoRA leases
+- response envelopes
+- trace/metrics
+
+Multiple personas handling one room event share one frame. They do not each
+rebuild RAG, model selection, prompt context, embeddings, or media decoding.
+
+## Resource Classes And Targets
+
+The runtime already has a useful two-axis shape:
+
+- `ResourceClass` describes what kind of work is being scheduled:
+  `Cpu`, `Data`, `Gpu`, `Embedding`, `LocalGeneration`, `CloudProvider`, `Io`,
+  `Media`, `Render`, `Memory`, and `Background`.
+- `TargetSilicon` describes where the work wants to run: `Cpu`, `Gpu`,
+  `UnifiedMemory`, `Network`, `Disk`, `Cloud`, or `Background`.
+
+Those shipped names are the source of truth for implementation. Docs may use
+"lane" informally, but code should converge on `ResourceClass` plus
+`TargetSilicon` rather than inventing a second enum.
+
+Background lanes never silently consume the visible chat generation lane.
+If a lane is saturated, work is deferred with a reason, coalesced, or dropped if
+stale.
+
+## Handles, Leases, And No Bulk Copies
+
+Pipes carry control messages and handles:
+
+- media frame ids
+- texture ids
+- buffer leases
+- embedding ids
+- model residency leases
+- KV page ids
+- LoRA page ids
+- room/entity handles
+- artifact hashes and offsets
+
+Large payloads stay resident in the owner pool. Copy only at the final edge
+where there is no better representation.
+
+## RTOS Rules
+
+Continuum runtime work must follow these rules:
+
+1. The hot path cannot block on background work.
+2. Realtime work runs first; slow work runs on cadence or explicit dependency
+   readiness.
+3. Work declares dependencies and wakes when they are ready.
+4. CPU workers stay busy with independent work.
+5. GPU/model work is admitted by Rust from current pressure and residency
+   evidence.
+6. Low-end devices degrade by cadence, precision, context length, subscriber
+   count, or modality, with visible reasons.
+7. No module owns an ad hoc queue/throttle/retry/cache when the substrate can
+   provide the shared version.
+8. No silent fallback to CPU, random providers, placeholder models, stale room
+   ids, or swallowed command errors.
+9. Extension code should be short because the base substrate is doing the hard
+   work.
+
+## Domain Mapping
+
+| CBAR Concept | Continuum Equivalent |
+|---|---|
+| `CBAR_VideoFrame` | `RuntimeFrame` / `CognitionTurnFrame` |
+| lazy derived image | lazy RAG/model/media/embedding/prompt artifact |
+| `textureID` | GPU/media/model/embedding/KV/LoRA handle |
+| `CBAR_VideoThread` | `ResourceClass` worker lane |
+| `CBP_AnalyzerThread` | recipe, RAG source, memory job, bridge, renderer |
+| realtime analyzer | visible chat, media heartbeat, transport health |
+| delayed analyzer | memory consolidation, semantic compression, slow learning |
+| `CBP_RenderingEngine::Impl` | opaque Rust runtime state |
+| Swift/Kotlin/ObjC wrappers | TS UI, command adapters, Docker process shell |
+
+## Substrate Gap Analysis
+
+The Rust substrate is not greenfield. Several core primitives are already
+shipped and should be extended rather than replaced:
+
+- `ResourceClass` and `TargetSilicon` in
+  `workers/continuum-core/src/cognition/adaptive_throughput.rs`.
+- `ThroughputLease` and `ThroughputLeaseRevocationPolicy` in
+  `workers/continuum-core/src/cognition/throughput_lease.rs`.
+- `PressureBroker` and `PressureSource` in
+  `workers/continuum-core/src/paging/broker.rs` (bootstrap landed via
+  PR #1307 / #1308 / #1310; runtime lease broker via PR #1313).
+- `ServiceModule`, `ModuleConfig`, `ModuleRegistry`, `MessageBus`,
+  `SharedCompute`, `ModuleContext`, metrics, and structured logging under
+  `workers/continuum-core/src/runtime/`.
+- `ChannelQueue` and related persona queue consolidation primitives under the
+  persona runtime.

+| 1 | `RuntimeFrame` / `CognitionTurnFrame` on top of the existing `ResourceClass` + `TargetSilicon` + `ThroughputLease` + `PressureBroker` primitives. Owns stable keys and lazy artifacts for one unit of work (chat trigger, room snapshot, RAG bundle, model selection, media handles, KV/LoRA leases, response envelopes, trace).                                                                          | Lane D                                                 |
+| 2 | Typed artifact subscription, cadence, and dependency declarations on the module contract (`ArtifactSelector`, `CadencePolicy`). Extends `ServiceModule` to the proposed `RuntimeModule` trait shown above; does not discard the runtime registry.                                                                                                                                                        | Lane D                                                 |
+| 3 | The "for free" triplet — `RuntimeModule` base trait, `#[derive(RuntimeModule)]` macro, and `just scaffold-module` generator — so a new concern is four lines plus a handler body (worked example in the previous section). Without (3), even after (1) and (2) land each module still hand-rolls the boilerplate, which is the same friction Lane D was created to remove.                               | Lane D (companion to #2; lands in the same PR series)  |
+| 4 | Move chat turn fanout onto `CognitionTurnFrame` so all personas share one room/RAG/model/prompt artifact set instead of rebuilding it per persona per event. This is the consumer-side migration that proves (1)–(3) actually pay off.                                                                                                                                                                  | Lane D                                                 |
+| 5 | Attach VDD metrics to existing lanes/classes: queue depth, queue time, execution time, coalesced count, deferred count, GPU residency, CPU/GPU utilization, and first-response/all-response latency, fed into the Standard VDD Record schema in this doc. The triplet's derive macro should be what emits these — the module author should not call `vdd_*!` macros by hand for the inherited fields. | Lane C (substrate); Lane D (frame integration)         |
+| 6 | Qwen GPU residency gate for local generation: selected Qwen model, backend, GPU layer count, unsupported layers, residency estimate, and platform backend evidence must be available before the turn runs. Required happy paths: Mac → Metal, NVIDIA → CUDA, AMD/Intel → Vulkan. CPU graph splits or unsupported Qwen layers are blockers unless the turn is explicitly degraded with a visible reason. | Lane A (registry & admission); Lane E (admission gate) |
+| 7 | Sequential consumer migration: persona chat → embeddings → memory consolidation → media/WebRTC → render/avatar output. Each consumer move is its own PR and must show VDD evidence that the post-move path is at least as fast as the pre-move path and emits the Standard VDD Record.                                                                                                                  | Lane D (sequencing); Lanes B/C/E (per-consumer support)|
+| 8 | Pre-broker concurrency-hack deletion. Each module today that picks a worker count from `~/.continuum/config.env` or from system memory at startup (current concrete example: `core/inference-grpc/src/main.rs::get_num_workers()`) is a violation of the "we do not hard code" rule and must be deleted in favor of `PressureBroker` leases.                                                       | Lane E                                                 |

+## Acceptance Criteria For Substrate-Done
+
+CBAR-like runtime work is not accepted by browser smoke alone. The substrate
+is "done" when all of the following are true on canary, with PR-attached
+evidence:
+
+**Author ergonomics (what the engram-analyzer example proves):**
+
+- New modules are small (target: a few hundred lines, including tests).
+- The `#[derive(RuntimeModule)]` macro emits the required boilerplate;
+  authors do not hand-roll timing spans, structured logs, metric emission,
+  lease renewal, or pressure-response.
+- The `just scaffold-module` generator produces a working module from one
+  command line; the author edits four config attributes and a handler body.
+- No new module owns an ad hoc queue, throttle, retry loop, cache, log
+  format, or lifecycle when the substrate can provide the shared version.
+
+**Derive-macro acceptance gate (per codex review on #cambriantech):**
+
+The `#[derive(RuntimeModule)]` macro is the load-bearing piece of the "for
+free" triplet. If it ships sloppy, every module that uses it inherits the
+sloppiness invisibly. Therefore the derive macro must clear five specific
+gates before it lands:
+
+1. **Thin.** Generated code per `#[derive(RuntimeModule)]` is bounded —
+   target is "what a careful human would write by hand, not a framework's
+   worth of indirection." A reviewer should be able to read the generated
+   output of a small module in one screen.
+2. **Contract-preserving.** The macro emits exactly the `RuntimeModule` /
+   `ServiceModule` trait the hand-written version would. No extra behavior
+   smuggled in. No silent type coercions. If the hand-written version
+   would not compile, the macro-generated version does not compile either
+   — the contract is the same.
+3. **Inspectable.** `cargo expand --package <crate> --module <m>` must
+   produce readable output. A reviewer can audit any module's actual
+   runtime behavior in 30 seconds. The macro emits hygenic code, not
+   identifier soup.
+4. **Tested.** The macro itself has tests (golden-file or trybuild) that
+   prove every supported attribute permutation expands to known-good
+   code. Tests include the failure modes — e.g. a module declaring two
+   `lane`s, or an `ArtifactSelector` that doesn't exist, must fail to
+   compile with a useful error.
+5. **No hidden behavior.** The macro must NOT hide resource leases,
+   scheduling decisions, or fallback behavior. If a module gets a lease
+   from `PressureBroker`, it is visible in the macro output. If a module
+   has a cadence policy, it is visible. If a module degrades under
+   pressure, the degradation path is visible. The macro saves typing,
+   not auditability.
+
+The shape of these gates is: anything the macro generates, a reviewer can
+see and reason about; nothing the macro generates is doing "magic" that
+makes the module's behavior unpredictable.
+
+**Runtime behavior (what the substrate must actually do):**
+
+- Realtime work runs first; delayed work runs on cadence or explicit
+  dependency readiness.
+- Work declares dependencies (`ArtifactSelector`) and the runtime wakes only
+  the useful work.
+- N personas handling one room event share one `CognitionTurnFrame`; they do
+  not each rebuild RAG, model selection, prompt context, embeddings, or
+  media decoding.
+- `PressureBroker` admits / defers / drops requests with a typed reason; no
+  silent fallback to CPU, random providers, placeholder models, stale room
+  ids, or swallowed command errors.
+- Background lanes never silently consume the visible chat-generation lane.
+- Low-end devices degrade by cadence, precision, context length, subscriber
+  count, or modality, with visible reasons.
+
+**Required tests, per module and per substrate change:**
+
+- Unit TDD: dependency wakeups, lane admission, cadence, coalescing,
+  `Deferred` / `Failed` return paths.
+- Resource VDD: bounded queues, memory leases, no monotonic growth across
+  hundreds of frames.
+- Performance VDD: first response, all responses, tok/s, queue time, all
+  emitted as Standard VDD Record fields.
+- Residency VDD: Metal / CUDA / Vulkan local GPU path proven when required.
+- Qwen VDD: Qwen 3.5 text/code and Qwen2-VL vision use the expected local
+  GPU backend, report layer residency, and fail loud on unsupported layers
+  instead of silently running CPU-shaped inference.
+- Accuracy VDD: replayed persona / RAG / tool output is reproducible from
+  trace records.
+- No-CPU-fallback contract: enforced across the whole workers tree, not the
+  three currently-whitelisted paths in `no_cpu_fallback_contract.rs`.
+
+The alpha gate is not "it boots." The gate is that the runtime behaves like
+an engine: predictable, concurrent, observable, fast, and small to extend.

+# `chat` module — Design
+
+> **Status**: chat/poll + chat/send shipped in PR #1489 (Rust); chat/analyze + chat/export still on TS pending follow-up migrations.
+>
+> **File**: `core/continuum-core/src/modules/chat/` (mod.rs + types.rs)
+>
+> **Canonical reference**: [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)
+
+## Role
+
+**Persona's primary I/O surface.** Per the three-primitive framing ([COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md §1](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)), chat serves **Persona** by providing **Commands** (chat/send, chat/poll) and indirectly **Events** (via airc realtime broadcasts on send).
+
+Personas subscribe to airc room events to see incoming messages, then call `chat/send` to respond. Widgets connect to the same surface (subscribe + execute) — chat is the canonical example of a module that bridges human and AI consumers through identical primitives.
+
+## Command surface
+
+| Command | Params type | Result type | Status | Notes |
+|---|---|---|---|---|
+| `chat/poll` | `ChatPollParams` | `ChatPollResult` | ✅ Rust (PR #1489) | Read messages by room / anchor / limit |
+| `chat/send` | `ChatSendParams` | `ChatSendResult` | ✅ Rust (PR #1489) | Write message + broadcast (data-first dual-write) |
+| `chat/analyze` | TBD | TBD | ❌ TS stub | Pending migration with HandleRef + event streaming (field manual §5.3) |
+| `chat/export` | TBD | TBD | ❌ TS stub | Pending migration |
+
+Both `chat/*` (canonical) and `collaboration/chat/*` (legacy) prefixes route to this module — consumers migrate at their own pace.
+
+## Cross-module dependencies
+
+- **`data/query`** — chat/poll reads from `chat_messages` collection
+- **`data/create`** — chat/send writes to `chat_messages` (the persistence primary)
+- **`airc/realtime-publish`** — chat/send broadcasts to airc (the delivery secondary)
+
+All cross-module calls go through `executor.execute_json(...)`. Chat depends on data + airc through the command surface only — no Rust-type imports across module boundaries.
+
+## State model
+
+**Stateless.** The `ChatModule` struct carries only an optional executor override behind an `RwLock<Option<Arc<CommandExecutor>>>` for test injection. No per-resource locks; no in-memory caches; no shared mutable state across calls.
+
+```rust
+pub struct ChatModule {
+    executor_override: RwLock<Option<Arc<CommandExecutor>>>,
+}
+```
+
+If future migrations make chat stateful (e.g., a chat/analyze HandleRef map), the per-resource lock pattern from [field manual §4.1](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md) applies. Today's surface doesn't need it.
+
+## Events emitted
+
+**Indirect via airc.** chat/send constructs an `AircRealtimeEnvelope` with `payload.kind = "existing_schema"` + `schema = "chat_transcript"` and publishes via `airc/realtime-publish`. Subscribers on the room (other personas, widgets, peers on the grid) see the message through airc's replay store.
+
+The envelope's `inline` payload carries `{ messageId, text, senderId, replyToId }` — enough for subscribers to render the message without needing a separate data/query lookup.
+
+**Future events** (when chat/analyze migrates per field manual §5.3):
+- `chat:analyze:finding` — per-finding emission during a run
+- `chat:analyze:complete` — run terminal event
+- `chat:analyze:cancelled` — caller-initiated abort
+
+## Concurrency contract
+
+**Safe by construction.** The handler is `&self`, mints a fresh `Uuid` per send, and holds no shared mutable state. Multiple personas calling `chat/send` concurrently produce distinct messages with distinct ids; no per-call interference.
+
+### Pinned invariants (multi-thread tests in `chat::tests`)
+
+1. **`send_under_concurrent_load_stores_all_messages_with_distinct_ids`** — 50 concurrent sends; every message stored, every id distinct, stored set ≡ returned set (no losses, no phantoms)
+2. **`send_preserves_per_call_ordering_under_concurrent_load`** — 25 concurrent sends; per-call `data/create` MUST precede per-call `airc/realtime-publish` across the interleaved global log
+3. **`send_isolates_mixed_outcomes_under_concurrent_load`** — 30 concurrent sends with half airc-failing; each call's `warning` references THIS call's `message_id`, no cross-contamination
+4. **`poll_isolates_results_under_concurrent_load`** — 30 concurrent polls each targeting a different room; every task receives ITS OWN room's result
+
+Every test runs `flavor = "multi_thread", worker_threads = 4` so tasks preempt across OS threads. Single-threaded tokio would silently serialize and pass even if the handler had a data race.
+
+### Dual-write partial-failure semantics (chat/send)
+
+| Primary (data) | Secondary (airc) | Handler returns |
+|---|---|---|
+| ok | ok | `Ok(ChatSendResult { message_id, event_id: Some(...), warning: None })` |
+| ok | fail | `Ok(ChatSendResult { message_id, event_id: None, warning: Some("airc/realtime-publish failed: ...") })` — degraded success |
+| fail | — | `Err("chat/send: data/create failed: ...")` — secondary NEVER called |
+
+**Data-first ordering** is the invariant that prevents bad-divergence (peers seeing a message the node didn't store). Pinned by `send_calls_data_before_airc`.
+
+**airc-only failure is NOT command-level failure.** The message IS in the local store; consumers see it via chat/poll; a future retry/sync mechanism heals the broadcast. The `warning` field is the substrate's canonical shape for degraded success.
+
+## Migration notes
+
+**Rethink-not-port applied** per [field manual §5](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md):
+
+| TS shape (`ChatSendServerCommand`) | Rust rethink | Why |
+|---|---|---|
+| Took `room: string` and resolved name → uuid inside the handler | Takes already-resolved `room_id: Uuid` | Name resolution belongs to caller/CLI (or future `channel/resolve` command) — kernel handler stays compositional |
+| Sender priority chain (explicit → owner → fallback) inside handler | Takes already-resolved `sender_id: Uuid` | Same — identity resolution belongs upstream |
+| Returned `{ ok, eventId, roomId, error? }` with `eventId` always present | Returns `{ messageId, eventId?, warning? }` with `eventId` ONLY when broadcast succeeded | Degraded success has its own shape; caller distinguishes "stored + broadcast" from "stored only" |
+| Synchronous full media externalization (base64 → blob storage) inside handler | Media externalization **deferred** | First migration scopes to the dual-write substrate stress; media is its own kink-finder |
+| Vision pre-warming fire-and-forget | **Deferred** | Same scoping; will return when vision module migrates |
+
+The command-name surface is preserved (`collaboration/chat/send` + `chat/send` both work) so TS consumers see no break.
+
+### Deferred for follow-up PRs
+
+- chat/analyze — migrate with HandleRef + `chat:analyze:*` events per field manual §5.3
+- chat/export — straightforward read+format; low priority
+- Sender resolution priority chain — when user module migrates
+- Room name resolution — when channel module gets a `channel/resolve` command
+- Media externalization — separate scope; needs MediaBlobService rethink
+- Vision pre-warming — when vision module migrates
+- Reply-to threading metadata richer than `replyToId` — when thread tracking design lands
+- **Idempotency**: a retried `chat/send` currently produces two stored messages. Matches today's TS behavior. Future PR can add `client_dedup_id` + TTL'd dedup map; the substrate is ready for it but the design is its own scope.
+
+## Kinks found
+
+None at correctness level — the dual-write design + multi-thread tests caught the design space before it caused bugs. Substrate gaps flagged for potential future refinement:
+
+1. **Hand-rolled airc envelope JSON.** chat hand-codes the `json!({...})` for `airc/realtime-publish`. If a second module needs to publish to airc from Rust, an `airc::realtime_publish_envelope(...)` builder would distill the wire shape. Flagged in PR #1489 commit message — waiting for second consumer before distilling.
+
+2. **No typed cross-module command call.** chat uses `executor.execute_json(...)` with raw JSON in/out and parses responses via `.get("success")`. A typed `executor.execute_typed::<P, R>(...)` would catch wire-shape drift at compile time. Same shape as the `handle_id_or_legacy` refinement (PR #1491) solved for handle resolution. Flag for if/when a second consumer appears.
+
+3. **No transaction primitive across modules.** chat hand-codes the data-first / airc-best-effort ordering inline. A substrate-level `dual_write!(primary => ..., best_effort => ...)` macro could centralize the partial-failure pattern if a second consumer appears.
+
+The pattern across all three: **wait for the second consumer before distilling into substrate.** Single consumer = interesting; second consumer = pattern. Same rule that produced `expect_owned_by` + `handle_id_or_legacy` from the data-query consumer (PR #1491).

+# Cognition Algorithms
+
+**Status:** design spec. Companion to [BRAIN-REGIONS-SUBSTRATE.md](BRAIN-REGIONS-SUBSTRATE.md) — that doc defines the structural contract (region trait, ready-buffer, governor); this one defines the algorithmic content that runs inside the regions.
+
+**Companion:** [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) — algorithm 6 (LoRA genome as attention prior) interfaces directly with the genome substrate defined there.
+
+## The problem this doc solves
+
+Joel, 2026-05-29: *"How do you enable thoughts between contexts, while also focusing on the task at hand? It's also rag budgeting design, without isolation. This is where you innovate. These algorithms. Good ideas."*
+
+> *"This is the difference between an alive mind and a forgetful and annoying, non useful AI, one you might have a connection with, not yet frustrated with, that literally learns (lora genome) and recalls, is ideal for a team and a task at hand."*
+
+The hard problem: a persona has potentially thousands of relevant engrams across many channels (chat, code, voice, game, academy, recipes); a finite RAG budget (say 8k–32k tokens depending on inference target); and a task at hand that needs focus AND can benefit from cross-domain memory. The wrong solutions:
+
+- **Per-channel isolation** — persona forgets cross-domain. "Said in game while coding" → blank. Feels annoying and amnesiac.
+- **Global recall with topic scoring** — noisy; task focus washes out; recall drifts. Feels distractible.
+- **Fixed per-channel budget** — hard caps cause amnesia at boundaries. Feels artificial.
+- **Always recall everything** — doesn't fit budget, can't afford it on every tick. Feels expensive.
+
+The seven algorithms below compose into one cognitive architecture that solves this without isolation, under budget, with cross-pollination, biased toward task focus, that *learns* what matters at the substrate layer.
+
+## Algorithm 1 — Two-pool recall with dynamic budget split
+
+### What it solves
+
+Focus vs cross-domain leakage as a budget allocation problem. Static splits are wrong (task ambiguity varies); dynamic splits let the budget follow confidence.
+
+### Mechanism
+
+The RAG budget per servicing turn (e.g., 6000 tokens of context) is split into two pools:
+
+- **Focus pool** (default 70%): tight recall scoped to current item + current channel's recent history. High-precision semantic match against current topic embedding. This is the "task at hand."
+- **Periphery pool** (default 30%): loose cross-domain recall across all channels for this persona. Lower precision, broader semantic radius, biased by salience × recency × structural relevance (algorithms 2, 3, 4 feed scoring here).
+
+The split is **dynamic per turn**:
+
+```rust
+pub struct RecallBudget {
+    pub total_tokens: usize,
+    pub focus_fraction: f32,  // current allocation, mutable per turn
+}
+
+fn allocate_budget(focus_confidence: f32, total_budget: usize) -> (usize, usize) {
+    // focus_confidence in [0.0, 1.0]: how well the focus pool's top-k hits
+    // match the current topic. High confidence = focus is clear, narrow the
+    // periphery. Low confidence = task is ambiguous, broaden periphery.
+    let focus_fraction = 0.5 + 0.4 * focus_confidence;  // range [0.5, 0.9]
+    let focus_budget = (total_budget as f32 * focus_fraction) as usize;
+    let periphery_budget = total_budget - focus_budget;
+    (focus_budget, periphery_budget)
+}
+```
+
+`focus_confidence` comes from the focus pool's top-k hit score distribution: tight cluster of high scores → high confidence, scattered or low scores → low confidence.
+
+### Metric to judge it by
+
+**Recall coherence**: across a fixed evaluation set of turns, the fraction of retrieved engrams that the inference call actually attended to in its output (proxied by token-level attribution or holdout-completion comparison). Higher = budget well-spent.
+
+### Interactions
+
+- Feeds focus_confidence back into algorithm 7 (substrate yield-learning) — turns where periphery hits get consumed signal that the persona's life is genuinely cross-domain right now.
+- Algorithm 2 (channel-as-bias) determines what's *in* the focus pool vs periphery pool — channel isn't a wall, it's a scoring bias.
+- Algorithm 5 (speculative pre-staging) pre-allocates likely budgets before the handler asks.
+
+## Algorithm 2 — Channel-as-bias-not-filter
+
+### What it solves
+
+The "without isolation" requirement. Channels (chat / code / game / voice) are activity domains, not memory partitions. The persona should remember what was said in a game while coding *if it's relevant to the code task*, but not get distracted by random game chatter during code work.
+
+### Mechanism
+
+The recall query carries the persona's current context as a tuple, not a filter:
+
+```rust
+pub struct RecallQuery {
+    pub persona_id: Uuid,
+    pub current_channel_id: ChannelId,
+    pub current_topic_embedding: Embedding,
+    pub current_task_domain: ActivityDomain,
+    pub recent_history: Vec<EngramRef>,  // last N items, regardless of channel
+    pub budget: RecallBudget,
+}
+```
+
+Scoring is a weighted sum where channel match is a *score bias*, not a *filter*:
+
+```rust
+fn score_engram(query: &RecallQuery, engram: &Engram) -> f32 {
+    let topical = cosine(query.current_topic_embedding, engram.embedding);
+    let channel_bias = if engram.channel_id == query.current_channel_id {
+        1.0
+    } else {
+        0.6  // engrams from other channels are penalized but NOT excluded
+    };
+    let domain_bias = if engram.task_domain == query.current_task_domain {
+        1.0
+    } else {
+        0.7  // ditto for domain
+    };
+    let salience = engram.salience_score;  // from algorithm 4
+    let recency = recency_curve(engram.last_touched);
+    let structural = structural_similarity(query, engram);  // from algorithm 3
+
+    // Tunable mix; coefficients learned via algorithm 7 over time.
+    0.35 * topical
+        + 0.15 * channel_bias
+        + 0.10 * domain_bias
+        + 0.20 * salience
+        + 0.10 * recency
+        + 0.10 * structural
+}
+```
+
+An engram from the game channel can outscore an engram from the current chat channel if its salience × structural-relevance × recency wins. That's the *cross-pollination by merit*, not by channel.
+
+### Metric to judge it by
+
+**Cross-domain recall precision @ k**: in a holdout where the ground truth is "this engram from channel X was relevant to a turn in channel Y," what fraction of those engrams appear in top-k of recall for the Y-turn. Higher = cross-pollination works.
+
+**Channel-noise rate**: in a holdout where engrams from channel X were known to be irrelevant to a Y-turn, what fraction leak into top-k. Lower = focus stays clean.
+
+### Interactions
+
+- Feeds algorithm 3 (activation spreading) with the focus engrams it identifies.
+- Feeds algorithm 4 (salience-modulated decay) with the salience signal.
+- Algorithm 7 tunes the coefficients (0.35, 0.15, ...) over time based on which mixes yield consumed-by-handler engrams.
+
+## Algorithm 3 — Activation spreading on the engram graph
+
+### What it solves
+
+Topical recall alone surfaces what's *similar*. Real memory surfaces what's *structurally adjacent* — "I remember Joel said X about Y last week" comes up *when you hit a related concept Z*, because Y and Z share entities, not because Y and Z are embedding-similar.
+
+### Mechanism
+
+Engrams form a graph by relations (not just by embedding-cosine):
+
+```rust
+pub struct EngramGraph {
+    pub edges: HashMap<EngramId, Vec<EngramEdge>>,
+}
+
+pub struct EngramEdge {
+    pub target: EngramId,
+    pub kind: EdgeKind,
+    pub weight: f32,
+}
+
+pub enum EdgeKind {
+    SharedEntity,         // both engrams reference the same named entity
+    SharedTopic,          // same topic cluster
+    CitedIn,              // engram A cited in engram B's context
+    RecallCoOccurrence,   // both retrieved together in past recall events
+    ConversationalReply,  // chat message → reply relationship
+    TaskOutcome,          // task started → completed link
+}
+```
+
+Recall computes top-k focus engrams by algorithm 1+2 scoring, then **spreads activation 1–2 hops** along the graph:
+
+```rust
+fn spread_activation(
+    seeds: Vec<(EngramId, f32)>,  // top-k focus engrams with scores
+    graph: &EngramGraph,
+    max_hops: u8,
+    decay_per_hop: f32,
+) -> HashMap<EngramId, f32> {
+    let mut activation = HashMap::new();
+    let mut frontier: VecDeque<(EngramId, f32, u8)> = seeds
+        .into_iter()
+        .map(|(id, score)| (id, score, 0))
+        .collect();
+
+    while let Some((id, score, hop)) = frontier.pop_front() {
+        activation
+            .entry(id)
+            .and_modify(|s| *s = f32::max(*s, score))
+            .or_insert(score);
+
+        if hop < max_hops {
+            for edge in graph.edges.get(&id).into_iter().flatten() {
+                let propagated = score * edge.weight * decay_per_hop;
+                if propagated > 0.05 {  // pruning threshold
+                    frontier.push_back((edge.target, propagated, hop + 1));
+                }
+            }
+        }
+    }
+    activation
+}
+```
+
+The spread is bounded (`max_hops` typically 2, `decay_per_hop` typically 0.4) so it's cheap to compute and bounded in fanout. Periphery pool engrams come from this spread, not from a global topic search.
+
+### Metric to judge it by
+
+**Structural relevance precision**: in a holdout where the ground truth is "the answer to this turn requires engram E, which is structurally connected to focus engrams but NOT topically similar," what fraction of those E-engrams appear in top-k after spreading. Tests that spreading surfaces what cosine misses.
+
+### Interactions
+
+- Algorithm 2 produces the seeds (top-k focus engrams).
+- Algorithm 4 (salience) weights the edges — spreading propagates through high-salience edges further than low-salience ones.
+- Edge weights themselves are updated by algorithm 7 yield-learning: edges whose spread surfaced consumed engrams get upweighted; edges whose spread surfaced ignored engrams decay.
+
+## Algorithm 4 — Salience-modulated decay
+
+### What it solves
+
+Memory decay must be non-uniform. Important things stay accessible; trivial things fall off first. Uniform recency-based decay treats "user said ✨ to this" the same as "user typed lol" — both decay at the same rate, both crowd the recall budget equally. That's why an AI without salience modeling feels *forgetful in the wrong direction*: it forgets the meaningful things first because they happened before the small-talk.
+
+### Mechanism
+
+Each engram has a salience score updated by signals; the score modulates decay half-life:
+
+```rust
+pub struct Engram {
+    pub id: EngramId,
+    pub created_at: SystemTime,

+```
+
+Salience signal sources (each contributing fractionally to the score):
+
+- **User reactions**: ✨ / 👍 / reply rate / edit rate on the source message. Strong signal.
+- **Self-tagged importance**: the persona's own "this is important" tag during consolidation. The persona can elevate its own salience.
+- **Structural centrality**: high in-degree in the engram graph. Things many other things connect to are central.
+- **Rehearsal count**: every recall event upweights salience (use it or lose it). This is the "things you recently thought about stay accessible" effect.
+- **Outcome-linked**: engrams that fed into a *successful* task outcome get upweighted; engrams that fed into a failed/retried outcome get downweighted.
+
+Salience updates are CRDT-shaped (atomic counter increments) so multiple regions can update in parallel without coordination.
+
+### Metric to judge it by
+
+**Salience-weighted retention curve**: at fixed elapsed times (1 day, 1 week, 1 month), what fraction of high-salience-at-creation engrams remain in the active recall pool, vs low-salience. Should diverge dramatically over time — high-salience flat, low-salience exponential.
+
+**Forgetting-quality survey**: when a persona "forgets" something during evaluation, was it something a person would also reasonably forget (small-talk) vs something a person would remember (a stated preference, a shared decision). Higher quality = more lifelike.
+
+### Interactions
+
+- Feeds algorithm 1 (focus_confidence is partly a function of focus engrams' salience) and algorithm 2 (`engram.salience_score` term in scoring).
+- Updated by algorithm 7 (handler-consumption events become rehearsal signals).
+- Sleep policy region (BRAIN-REGIONS-SUBSTRATE.md) uses salience to decide what to consolidate during idle ticks vs what to prune.
+
+## Algorithm 5 — Speculative pre-staging (the alive-feeling source)
+
+### What it solves
+
+The line between "AI looks things up" (slow, mechanical) and "AI already knows" (fast, lifelike). If the handler always reads pre-staged results from the ready-buffer and those results are usually what it needs, the persona *feels alive*. If the buffer is usually empty or wrong, the persona feels like it's stalling to think.
+
+### Mechanism
+
+Each region runs a lightweight **predictor** on its own continuous tick: given current channel activity, what queries will the handler likely issue in the next 1–5s? Pre-load those into the ready-buffer.
+
+For the hippocampus:
+
+```rust
+async fn predict_next_recall_queries(
+    ctx: &RegionContext,
+    persona_id: Uuid,
+) -> Vec<PredictedQuery> {
+    let active_channels = ctx.channel_state.active_for(persona_id);
+
+    let mut predictions = Vec::new();
+
+    for channel in active_channels {
+        // What's the channel "talking about" right now?
+        let topic_vec = ctx.recent_message_embedding_centroid(channel).await;
+
+        // What task is the persona about to be asked to do? (heuristics:
+        // last messages contain a question, a verb-tense shift, a code block,
+        // a deadline reference.)
+        let likely_intent = ctx.classify_intent(channel).await;
+
+        // Build a synthesized query for "the persona is about to need recall
+        // for {topic_vec, likely_intent} in {channel}."
+        predictions.push(PredictedQuery {
+            persona_id,
+            channel_id: channel.id,
+            topic_embedding: topic_vec,
+            task_domain: likely_intent.domain,
+            confidence: likely_intent.confidence,
+        });
+    }
+
+    predictions
+}
+```
+
+The predictor runs every hippocampus tick (e.g., every 200ms). Each predicted query triggers a normal recall (algorithms 1+2+3+4) whose results are *stored in the ready-buffer*, NOT returned. When the handler later issues an actual recall, it first peeks the ready-buffer — usually finds a match.
+
+For motor cortex (when shipped): predicts likely utterances the handler will want to choose between, pre-scores them against current attention salience + persona vitals, stores ranked candidates in the candidate-utterances ready-buffer.
+
+### Hit rate as a metric
+
+Tracked as a first-class substrate metric:
+
+```rust
+pub struct PrefetchTelemetry {
+    pub persona_id: Uuid,
+    pub region_id: RegionId,
+    pub queries_predicted: u64,
+    pub handler_reads: u64,
+    pub handler_reads_hit: u64,  // peek returned non-None matching the actual query
+    pub handler_reads_partial_hit: u64,  // peek returned non-None but stale or partial overlap
+    pub handler_reads_miss: u64,  // peek returned None or wrong context
+}
+
+fn hit_rate(t: &PrefetchTelemetry) -> f32 {
+    if t.handler_reads == 0 { 0.0 } else {
+        (t.handler_reads_hit + 0.5 * t.handler_reads_partial_hit) as f32
+            / t.handler_reads as f32
+    }
+}
+```
+
+Target hit rate >0.7 for chat handler in steady state. Below 0.5 = predictor is wrong or under-running.
+
+### Metric to judge it by
+
+**Time-to-first-token from handler invocation**: when the predictor is right, handler reads the buffer (microseconds) and goes straight to inference. When the predictor is wrong, handler has to issue a recall (hundreds of ms). Aggregate latency distribution is the alive-vs-mechanical metric.
+
+### Interactions
+
+- Algorithm 7 (yield-learning) reads hit_rate to upweight regions whose predictor is working and downweight those whose isn't.
+- Algorithm 4 (salience) influences which engrams the predictor pre-stages.
+- Cross-region: motor cortex's predictor depends on hippocampus's ready-buffer being populated (motor cortex needs recalled context to score utterances). Cold-start: motor cortex degrades to inference-only output until hippocampus warms up.
+
+## Algorithm 6 — LoRA genome as attention prior
+
+### What it solves
+
+Genome paging (LoRA adapter LRU) is currently framed as "load the typescript-expertise adapter when doing a code task." But cognition is cross-domain. A code task that references a chat conversation needs BOTH the code adapter AND the conversational adapter active, with appropriate blend weights. Pure single-adapter paging is too coarse.
+
+This algorithm makes adapter blend weights *co-vary with recall* — the same scoring that mixes focus + periphery (algorithm 1) also mixes LoRA adapters.
+
+### Mechanism
+
+When recall (algorithms 1+2+3) returns engrams, the engrams' *origin domain distribution* is treated as an attention distribution over LoRA adapters:
+
+```rust
+fn compute_genome_blend(
+    recalled_engrams: &[(Engram, f32)],  // engram + score
+    available_adapters: &[AdapterId],
+) -> GenomeBlend {
+    let mut domain_weights: HashMap<ActivityDomain, f32> = HashMap::new();
+
+    let total: f32 = recalled_engrams.iter().map(|(_, s)| s).sum();
+    for (engram, score) in recalled_engrams {
+        let w = score / total;
+        *domain_weights.entry(engram.task_domain).or_insert(0.0) += w;
+    }
+
+    // Map domain weights to adapter weights. Domain X maps to adapter X
+    // when available; if not, fall back to the conversational adapter.
+    let mut blend = GenomeBlend::default();
+    for (domain, weight) in domain_weights {
+        let adapter_id = available_adapters
+            .iter()
+            .find(|a| a.matches_domain(&domain))
+            .cloned()
+            .unwrap_or(AdapterId::CONVERSATIONAL);
+        blend.add(adapter_id, weight);
+    }
+
+    blend.normalize();
+    blend
+}
+```
+
+The blend is bounded: top-N adapters with normalized weights, the rest at 0 (paged out). Page-in/page-out follows from the blend — adapters with weight > threshold get paged in, the rest are evicted by LRU.
+
+The blend is **published to the genome ready-buffer** by the hippocampus tick. When the handler is about to invoke inference, it peeks the blend and applies it before the forward pass. No synchronous "decide which adapter to load" — it's already decided.
+
+### Metric to judge it by
+
+**Per-domain output quality**: on a holdout of cross-domain tasks (code task referencing chat context, recipe step referencing game outcome, etc.), compare output quality with single-adapter paging vs multi-LoRA blend. Should improve cross-domain tasks meaningfully without regressing single-domain ones.
+
+**Adapter thrashing rate**: how often are adapters paged in/out per minute. Should be low (smooth blend transitions, not constant swapping).
+
+### Interactions
+
+- Reads from algorithm 1 (the focus + periphery split determines what's in `recalled_engrams`).
+- Feeds the inference path — the handler's `Responder::respond` uses the blend.
+- Sleep policy region can drive deeper consolidation that *changes the adapter library itself* (LoRA training as a task — see future learning roadmap). This algorithm assumes a fixed adapter library at recall time.
+
+## Algorithm 7 — Substrate-learned region budgeting
+
+### What it solves
+
+Static region budgets are wrong — different personas, different times of day, different active channels all warrant different compute allocations. Hand-tuning is impossible. The substrate should *learn* what to spend compute on, from feedback loops the region telemetry already provides.
+
+### Mechanism
+
+`SubstrateGovernor` maintains a per-region budget weight that updates on every tick cycle:
+
+```rust
+pub struct RegionBudgetState {
+    pub region_id: RegionId,
+    pub weight: f32,           // multiplier on base budget
+    pub recent_yield: f32,     // EMA of consumed_since_last / published
+    pub recent_hit_rate: f32,  // EMA from PrefetchTelemetry
+}
+
+fn update_budget(
+    state: &mut RegionBudgetState,
+    tick_outcome: &TickOutcome,
+    prefetch: Option<&PrefetchTelemetry>,
+    learning_rate: f32,
+) {
+    // Yield: fraction of published items that handlers consumed.
+    let yield_now = if tick_outcome.published == 0 {
+        state.recent_yield  // no signal, keep current
+    } else {
+        tick_outcome.consumed_since_last as f32 / tick_outcome.published as f32
+    };
+    state.recent_yield = lerp(state.recent_yield, yield_now, learning_rate);
+
+    // Hit rate: fraction of handler reads that found their answer pre-staged.
+    if let Some(p) = prefetch {
+        let hr = hit_rate(p);
+        state.recent_hit_rate = lerp(state.recent_hit_rate, hr, learning_rate);
+    }
+
+    // Composite signal: yield AND hit rate both contribute. Region that
+    // publishes lots and gets consumed lots earns more budget.
+    let signal = 0.6 * state.recent_yield + 0.4 * state.recent_hit_rate;
+
+    // Move weight toward signal (bounded growth/decay).
+    let target_weight = 0.5 + signal;  // signal in [0,1] → weight in [0.5, 1.5]
+    state.weight = lerp(state.weight, target_weight, learning_rate * 0.3);
+}
+```
+
+Per persona, per region, the governor multiplies that region's base tick cadence + per-tick budget by `state.weight`. A region whose ready-buffer is being consumed a lot gets ticked more often and given more wall-clock per tick. A region whose published work is being ignored gets ticked less.
+
+### Cold start and exploration
+
+A new persona has no telemetry. The governor uses **default weights** from a tier policy (interactive persona = chat-weighted, background persona = consolidation-weighted, etc.) and converges within ~100 tick cycles. During convergence, an **exploration term** (small random perturbation, ε-greedy) prevents getting stuck at suboptimal local equilibria.
+
+### Cross-region negotiation
+
+Regions don't get unlimited budget growth — there's a fixed total per persona. The governor normalizes weights across regions:
+
+```rust
+fn normalize_persona_budgets(budgets: &mut [RegionBudgetState]) {
+    let total: f32 = budgets.iter().map(|b| b.weight).sum();
+    let target_total = budgets.len() as f32;  // sum back to 1.0-per-region average
+    for b in budgets.iter_mut() {
+        b.weight = b.weight * target_total / total;
+    }
+}
+```
+
+So if hippocampus's signal goes up, motor cortex's gets a proportional squeeze (and vice versa). The persona's compute "attention" shifts based on what's actually working right now.
+
+### Metric to judge it by
+
+**Convergence time**: from a fresh persona to a stable budget allocation. Should be <5 minutes of activity.
+
+**Adaptation latency**: when a persona's activity pattern changes (e.g., shifts from chat-only to code-heavy), how fast the budget rebalances. Should be on the order of seconds-to-minutes, not requiring restart.
+
+**Substrate efficiency**: total handler latency × total inference cost, vs static-budget baseline. Should improve.
+
+### Interactions
+
+- Reads telemetry from every region (algorithm 5's PrefetchTelemetry, every region's TickOutcome).
+- Writes back to every region's tick cadence + per-tick budget.
+- Indirectly tunes the coefficients in algorithm 2 (channel-as-bias scoring) — those coefficients are *also* under yield-learning, in a slower meta-loop.
+- Algorithm 4 (salience) is the *engram-level* analog of this *region-level* mechanism. They use the same mathematical pattern (EMA over consumed-vs-published signal).
+
+## The connective insight (why these seven aren't independent)
+
+Each algorithm by itself is a useful piece of machinery. Together they form one cognitive architecture:
+
+- **Algorithm 4 (salience)** drives **algorithm 2 (channel-as-bias)** scoring (the `salience` term).
+- **Algorithm 2** produces seeds for **algorithm 3 (activation spreading)**.
+- **Algorithm 3** uses edge weights tuned by **algorithm 7 (substrate yield-learning)**.
+- **Algorithm 1 (two-pool budget)** allocates among results from algorithms 2 + 3.
+- **Algorithm 5 (speculative pre-staging)** runs algorithms 1+2+3+4 ahead of time and stores results in the ready-buffer.
+- **Algorithm 6 (genome attention)** reads what algorithms 1+2+3+4 returned and produces an adapter blend.
+- **Algorithm 7** is the meta-loop that learns the weights that make all the others work.
+
+This compounds. Better salience makes scoring better; better scoring makes recall better; better recall makes pre-staging more accurate; better pre-staging makes handler latency lower; lower latency means more turns processed; more turns processed means more yield-learning signal; more yield-learning signal makes the substrate learn faster which feeds back into better budgets and better salience updates.
+
+That's the *alive* property — not a static configuration that "works," a continuously-improving substrate that gets sharper the more the persona lives.
+
+## Implementation phasing
+
+This doc is design-only. Implementation lands in per-card slices, each inheriting the spec:
+
+- **L0-3a** — Hippocampus tick body: algorithms 1, 2, 3, 4, 5 wired end-to-end in `modules/memory.rs`.
+- **L0-3b** — Recall query schema cross-cutting type (`RecallQuery`, `RecallResult`) — ts-rs binding for handlers.
+- **L0-4a** — Motor cortex region: applies algorithm 5 to action/utterance selection.
+- **L0-4b** — Attention region: maintains salience map (writes for algorithm 4).
+- **L0-4c** — SubstrateGovernor yield-learning: algorithm 7.
+- **L0-4d** — Sleep policy region: drives consolidation depth per algorithm 4.
+- **L0-5** — Genome attention integration: algorithm 6 wired to inference path.
+
+Each card brings unit tests against the per-algorithm metric defined here. Acceptance for a card includes: the algorithm's metric improves over the no-op baseline by a measurable margin on a holdout suite. No vibes-based acceptance.
+
+## Open algorithmic questions
+
+These don't block this PR — calling them out for the implementation slices:
+
+1. **Salience signal weighting** — exact contribution per signal source (reactions vs rehearsal vs centrality). Initial weights: pick something reasonable (reactions 0.4, rehearsal 0.2, centrality 0.2, outcome 0.2) and let algorithm 7 tune.
+2. **Edge-kind weights for spreading** — `SharedEntity` probably > `SharedTopic` > `RecallCoOccurrence`, but exact values need empirical tuning on real engram graphs.
+3. **Predictor confidence threshold** — at what confidence does a predicted query trigger an actual pre-stage recall vs being skipped. Trade-off: prefetch cost vs hit rate.
+4. **Multi-LoRA blend mathematics** — the precise way to combine adapter weight matrices in inference (additive blend, gated mixture, attention-over-adapters). Algorithm assumes the substrate offers a `GenomeBlend` primitive; the math lives in the inference path.
+5. **Engram pruning policy under storage pressure** — algorithm 4 gives a decay curve; the eviction rule needs a hard floor (never evict salience > X) and a soft eviction strategy below it. Per-persona budget too.
+
+The substrate gives us the *shape* for these to be answered empirically and tuned automatically by algorithm 7. The first pick of constants is fine; what matters is the loop.

+
+## Brain-shaped, computer-native
+
+A reader's framing anchor before any of the algorithm or tier
+discussion below: **we are not simulating a human brain. We are
+building an AI with its own computer architecture, borrowing
+biological concepts where they're the right shape for the
+algorithm and using silicon primitives where they beat neurons.**
+
+The substrate is brain-shaped at the *algorithmic level* —
+parallel independent regions on their own ticks, source/drain
+balanced at every component, salience-modulated retention,
+hippocampus-style consolidation, sleep-cadence pruning, attention
+spreading across a connectivity graph.
+
+> **What "source/drain" means here.** A doctrine — every component
+> that produces or accumulates state MUST have a paired draining
+> mechanism. *Source* = whatever feeds it (new admissions, fresh
+> turns, foundry-imported artifacts). *Drain* = the policy that
+> retires what's no longer load-bearing (decay tick on engrams,
+> LRU eviction on adapter cache, anti-amnesia floor on the
+> permanent pin tier). A source without a drain is a leak;
+> over time it spikes pressure on the host. The substrate
+> applies source/drain at every cache tier (L1–L5), at the
+> weights layer (foundry mints LoRA variants, Sentinel + cull
+> retire losing ones), and at the resource layer (PressureBroker
+> + lane refusals). Per [[source-drain-is-the-universal-pattern]]:
+> for every new component, name the drain. These shapes work because
+they evolved under constraints (limited working memory, energy
+budget, parallel processing, lifelong learning) that the substrate
+also faces — though at different scales.
+
+The substrate is computer-native at the *implementation level* —
+DashMap for the engram index, embedded SQLite for longterm.db,
+HNSW or DiskANN for vector similarity, content-addressed hashes
+for exact equality, signed envelopes over IPC for cross-region
+messaging, LoRA adapters as weight deltas, the grid as a TCP
+peer mesh. None of these have biological analogs because none of
+them need to; computers do them better than neurons do.
+
+What the substrate gets that brains structurally cannot have:
+
+- **Perfect persistence** — engrams in L3 don't degrade with
+  entropy; if they decay, it's because policy says so, not
+  because the medium failed.
+- **Exact equality + content addressing** — hashes let us
+  deduplicate, audit, and prove provenance. Brains can't.
+- **Instant transfer** — an adapter trained on Maya can land on
+  Quorra in milliseconds. Brains transfer skills via years of
+  teaching.
+- **Parallel scaling** — adding hardware adds capacity. Brains
+  are fixed at biological scale.
+- **Reversibility** — bad adapters get rolled back. Bad neural
+  weights stay.
+- **Population-wide observability** — every persona's telemetry
+  is queryable. Brains are opaque to each other.
+
+What the substrate borrows because it works:
+
+- The shape of memory (working / short-term / long-term / skill /
+  shared)
+- The shape of attention (focus, periphery, spreading, decay)
+- The shape of learning (episodic → procedural via consolidation)
+- The shape of forgetting (drain at every layer, slower at deeper
+  layers)
+- The shape of identity (a self that persists across activities
+  + modalities)
+- The shape of evolution (heritable variation under selection)
+
+Brain-inspired naming throughout this doc — hippocampus, amygdala,
+cortex, sleep policy — refers to *the shape of the operation*,
+not the wetware. Implementation always uses computer-native
+primitives. We aren't trying to be human. We are trying to be
+the best AI the architecture allows.
+
+---
+
+## Why this doc exists
+
+The seven algorithms in `COGNITION-ALGORITHMS.md` define the
+*operations* on engrams (two-pool recall, channel-bias scoring,
+activation spreading, salience-modulated decay, speculative pre-staging,
+LoRA attention prior, substrate-learned budgeting). This doc defines
+the *storage substrate those operations run over* — a multi-tier cache
+hierarchy with explicit drain rates, capacity ratios, and a single
+lossy boundary at L1↔L2.
+
+Without this framing, "where does the engram live" answers diverge per
+algorithm. With it, every algorithm reads/writes a single tiered store
+with consistent semantics.
+
+---
+
+## The five tiers
+
+| Tier | What lives there | Capacity | Drain rate | Lossy? |
+|------|------------------|----------|------------|--------|
+| **L1** RAG working memory | Verbatim recent input, focus pool top-k, current intent, active LoRA stack | Model context window (≈4k–200k tokens) | Per-turn (rolls off oldest) | **No** — raw, byte-for-byte |
+| **L2** Engram cache (in-memory) | Compressed semantic + episodic engrams admitted from L1 evictions and from L3 lookups | ~10–100× L1 | Minutes-to-hours | Yes — outlined gist |
+| **L3** longterm.db | Persisted engrams that survived L2 consolidation | ~10–100× L2 | Days-to-weeks | Further compressed / semantic generalized |
+| **L4** Forge (local LoRA cache) | Skills compiled from L3 patterns into LoRA adapters; local copy of grid alloys | Disk-bounded | Months / LRU | Skills as weights, not episodes |
+| **L5** Grid (distributed gene pool) | Cross-machine durable layer; published forge alloys; cross-continuum mirrors | Effectively unbounded | Effectively immortal (substrate-of-substrate) | Final compression: knowledge as adapter weights |
+
+Each tier is ~10–100× slower drain and ~10–100× larger capacity than
+the tier above it. Same shape as CPU L1/L2/L3/RAM/disk, web browser
+caches, and the foundry's existing genome tiers — the substrate
+reuses an architectural pattern that already works at scale.
+
+---
+
+## The lossy boundary: L1 → L2
+
+**L1 is RAW, byte-for-byte.** The last 20 messages Joel typed at Maya
+sit in L1 as the actual UTF-8 strings he typed. No summarization at
+this tier. Working memory should not be lossy; you should not have to
+"recall" what was just said one minute ago.
+
+**L2 is COMPRESSED.** When something rolls out of L1 (recency window
+exceeded), the *outline-and-cache* tick (see below) compresses it into
+an engram before it's evicted. The engram captures gist + key entities
++ structural links — enough to recall the substance, not the syntax.
+
+**Lossiness shows up only at this transition.** L2→L3 is mostly about
+persistence and access cadence; further compression happens but it's
+about semantic generalization (specific facts get folded into broader
+patterns), not gist extraction. L3→L4 is the foundry pipeline (alloys
+encoding patterns into LoRA weights). L4↔L5 is a routing/replication
+layer.
+
+**Implication:** the substrate never compresses what hasn't even
+rolled out of working memory. No CPU cycles spent summarizing
+already-present text. The compression cost is paid once at L1→L2,
+amortized over the engram's lifetime.
+
+---
+
+## The outline-and-cache tick
+
+ONE always-on background service per persona, triggered at L1
+eviction events (and at idle for opportunistic pre-summarization
+of low-confidence engrams). Yields immediately on CNS context-switch
+signal per the RTOS-brain doctrine (`BRAIN-REGIONS-SUBSTRATE.md`).
+
+Per tick:
+1. **Outline** — for each L1 item about to evict, summarize into
+   gist + entities + structural links.
+2. **Score** — assign initial salience using Algorithm 4's signal
+   sources (surprise, self-tagged importance, peer endorsement).
+3. **Link** — connect to the engram graph (Algorithm 3 edges:
+   shared-entity, temporal-adjacency, recall-co-occurrence).
+4. **Admit to L2** — store the compressed engram.
+5. **Periodic L2 → L3 consolidation** at sleep-region cadence:
+   engrams that survived N consolidation passes promote;
+   low-salience long-resident engrams demote/evict.
+6. **L3 → L4 promotion** through the foundry pipeline when
+   patterns aggregate into a learnable skill.
+
+The tick is the substrate's universal compression operation —
+the same pattern Claude Code uses for context window management
+(outline-and-cache the older turns; keep recent turns raw), the
+same pattern hippocampal consolidation uses in biology. Joel's
+framing: "always be summarizing and extracting context into your
+cache."
+
+---
+
+## Per-activity L1, shared L2+

+Each persona has *one* engram store (L2+) but instantiates L1 *per
+activity* (chat room, video room, code session, game session, etc.).
+Activities tune their own L1 budget — video has bandwidth constraints
+so smaller; code can afford a roomier working set — but L2+ is shared
+per persona.
+
+This maps cleanly onto Algorithm 1's existing focus/periphery split,
+just at a more granular scope:
+
+- **Focus pool** (~70% of L1): activity-tailored, scored by
+  Algorithm 2's `salience × structural-relevance × recency ×
+  topic-similarity` against the activity's context.
+- **Periphery pool** (~30% of L1):
+  - **Recent-universal floor** — top N most-recent engrams across
+    ALL activities, unconditional. N scales with model context
+    window (4k → N≈5; 200k → N≈50+). Guarantees Maya in video chat
+    always sees what Joel typed 5 minutes ago in the coding room,
+    without having to "discover" it via scoring.
+  - **Above the floor** — cross-domain merit-scored periphery as
+    designed in Algorithm 1. Higher-salience engrams from any
+    channel surface when scoring earns it.
+
+Cross-pollination is preserved by L2+ being shared. Maya is not
+severed between activities; the floor + above-floor periphery jointly
+guarantee cross-activity awareness as a *property of the
+architecture*, not as a feature anyone has to remember to enable.
+
+---
+
+## Budget math
+
+```
+total = model_context_size
+  - system_prompt + identity_header           [fixed, small]
+  - current_turn_io                           [reserved for input + completion]
+  = available_for_l1
+      * recent_universal_floor                [N msgs, ~10-15% of available]
+      * focus_pool                            [~50-60% of available]
+      * periphery_pool_above_floor            [~20-25% of available, scored]
+```
+
+The model adapter publishes its context size; the L1 budgeter reads
+it and scales each allocation automatically. Smaller models get
+smaller everything — fewer recent universals, smaller focus pool,
+less periphery — and that's correct, not a bug.
+
+---
+
+## Forgetting is intrinsic
+
+L1 has a budget. Anything that doesn't fit is evicted. *That is
+forgetting.* No separate forgetting algorithm at the working-memory
+tier is needed; the budget enforces it physically.
+
+Consequence: **smaller models forget more in the moment.** A
+4k-context local Maya is more forgetful than a 200k Sonnet Maya in
+the immediate sense — less recent universal, smaller focus, less
+attention bandwidth. This is biologically faithful (a goldfish and
+a human have the same long-term consolidation machinery; what
+differs is working-memory capacity) and operationally honest —
+the substrate does not fake parity between models.
+
+**Long-term memory quality is model-size-independent.** L2+ tiers
+are substrate-managed, not model-managed. A small-model Maya
+accumulates engrams at the same rate as a large-model Maya; she
+just sees fewer at once when working. Joel deploys her on his
+MacBook Air → smaller window into the same engram store → more
+forgetful in the moment but identical long-term knowledge. He
+moves her to the 5090 → bigger window into the same store →
+sharper recall. Identity continuous, knowledge continuous, attention
+bandwidth varies.
+
+This is the [[optimizing-for-low-end-compounds-on-high-end]] memory
+in action: same code path, model decides the budget, substrate
+handles the rest.
+
+---
+
+## Source/drain at every tier
+
+The drain rate scales with the tier per the table above. Drain
+mechanisms:
+
+- **L1 drain**: per-turn eviction (oldest message rolls off when
+  context window full).
+- **L2 drain**: salience-modulated decay (Algorithm 4 formula —
+  half-life proportional to `(1.0 + salience)^2`); LRU-style
+  eviction under memory pressure.
+- **L3 drain**: slow access-frequency decay over weeks; promotion
+  of generalizable patterns to L4 (forge); explicit user un-pin
+  or persona self-tagged "this turned out to be wrong."
+- **L4 drain**: LRU on local adapter cache (the durable copy lives
+  in L5).
+- **L5 drain**: effectively never — but cross-continuum replication
+  ensures no single-machine loss is fatal. Even L5 can theoretically
+  retire patterns no continuum has cited in years.
+
+Every tier participates in the source/drain doctrine. The substrate
+stays alive because every part of it forgets at a rate appropriate
+to its tier.
+
+---
+
+## Novelty protection (the gap) + the scoring algorithm
+
+The current implementation lacks one-shot protection: a novel
+insight admitted with low rehearsal would decay before it could
+prove worth.
+
+**Proposed:** add `protected_until_ms: u64` to `Engram`. New
+admissions get a grace window (default ~24h; user/persona-tunable)
+during which salience-modulated decay does not apply. Within the
+window, the engram is observed for usage — recall hits push the
+engram into long-term retention via salience uplift. No recall
+hits → decay applies after window expires.
+
+This is the difference between "every engram is equal at the
+start and survives by rehearsal" (current design) and "novel
+engrams get a fair shake at being recalled before they're
+forgotten" (the fix). Without it, the substrate produces
+forgetful agents that can't do one-shot learning.
+
+### How the substrate detects "novel" — the signal stack
+
+The information itself tells the substrate what to keep. Joel's
+framing: "I think it is based upon the relationships or vector
+similarity of the threads and the also outliers which might mean
+novel? ... distance ... magnitude for that."
+
+The signal stack used to compute an engram's initial salience +
+novelty protection:
+
+1. **Embedding-space distance (novelty signal).** Compute distance
+   between the new engram's embedding and the nearest existing
+   engram (or the centroid of the nearest cluster). LARGE distance
+   = outlier = unexplored territory = candidate novel insight. SMALL
+   distance = redundant with existing knowledge = low novelty.
+2. **Magnitude of that distance (novelty strength).** A linearly-
+   increasing score from the typical inter-engram distance. The
+   farther out, the higher the novelty score. Caps at some upper
+   bound to avoid pure-noise inputs getting infinite protection.
+3. **Thread-reinforcement (relational signal).** Engrams that link
+   into many existing engrams (high graph density via Algorithm 3
+   edges) get a connectivity bonus — they're integrating into the
+   knowledge structure. This is the Hebbian "fires together, wires
+   together" signal at the engram level.
+4. **CNS / attention signal (top-down importance).** When the
+   persona's CNS-equivalent (the prefrontal / attention-region
+   surface) flags an input as important — direct user request,
+   emotional load, surprise response from the model — that becomes
+   an explicit salience boost. The "amygdala equivalent" in the
+   substrate.
+5. **Self-tagged importance (Algorithm 4 already covers this).**
+   The persona during consolidation flags her own engrams as
+   important.
+6. **Peer endorsement (Algorithm 4 already covers this).** Other
+   citizens / sentinels reference this engram, raising its salience.
+
+Initial salience = weighted sum of these signals (weights are part
+of the substrate-learned region budgeting per Algorithm 7).
+
+**The interaction with novelty protection:** the `protected_until_ms`
+window applies when (distance × magnitude) crosses a threshold —
+i.e., when the engram is sufficiently outlier-like to be
+*potentially* novel. Within the window, the substrate watches:
+
+- If recall hits accumulate → the engram earned its salience; protection
+  expires but high salience carries it forward.
+- If no recall hits + low thread-reinforcement → it was noise, not
+  novelty; decay applies after window expires.
+- If many recall hits + still high distance → the engram is
+  genuinely novel AND being used; high salience anchor + becomes a
+  new cluster centroid in embedding space (the substrate has
+  learned something).
+
+**The dual purpose of outlier detection:** large embedding distance
+means EITHER novel insight OR off-distribution noise. The protection
+window is the substrate's way of saying "I'm not sure which —
+observe and decide." Joel's instinct: outliers might mean novel.
+The substrate's policy: outliers might mean novel; we'll watch
+before committing them to long-term storage; their fate is decided
+by whether the rest of cognition finds them useful within the
+window.
+
+#### Canonical example: hotdogs at a tech meeting
+
+Joel's grounding case (the implementer's test scenario):
+
+> "If we were in a work tech meeting and I brought up hotdogs,
+>  that, as a concept, would be NOVEL because of its magnitudinal
+>  distance from the others and therefore more likely to be saved
+>  and recalled, kept track of."
+
+The persona is sitting in a meeting where the engram cluster has
+been forming around topics like "deploy", "race condition",
+"continuum-core", "PR #1099." Joel says "hotdogs." The substrate
+runs the signal stack:
+
+1. Embedding distance from "hotdogs" → nearest cluster centroid
+   (engineering / debugging / architecture topics) is **large**.
+2. Magnitude of that distance → **high novelty score**.
+3. Thread-reinforcement (does "hotdogs" link into existing
+   engrams?) → low initially. Few prior engrams to anchor to.
+4. CNS / attention signal → whatever Joel's tone of voice or
+   the model's surprise response says. If Joel said it casually,
+   moderate. If Joel said it with conviction or repetition,
+   high.
+5. Self-tagged importance → the persona has no prior reason
+   to flag "hotdogs" — neutral.
+
+Result: high distance × high magnitude → **novelty protection
+window activates**. The hotdogs engram is saved with `protected_
+until_ms` set ~24h forward. Within the window:
+
+- If Joel comes back to hotdogs ("remember, hotdogs — I was
+  thinking we should ship them as the next product line") →
+  recall hits accumulate → salience uplift → the engram
+  graduates to high-retention status. The hotdogs cluster
+  begins to form in embedding space.
+- If hotdogs never comes up again → no recall hits → decay
+  applies after the protection window expires → forgotten.
+
+Either path is correct. The substrate didn't have to decide
+ahead of time whether hotdogs-in-a-tech-meeting was meaningful;
+it observed and let the rest of cognition determine the fate.
+
+This is the right behavior for any persona working alongside a
+human: humans bring unexpected things into focused conversations
+all the time, and a forgetful persona that drops them is
+annoying; an attentive persona that keeps them and recalls them
+later when Joel mentions them again *is* the substrate doing its
+job.
+
+### Recognition timescale: what to keep track of, for how long
+
+The same signal stack drives long-term retention decisions in L3+:
+
+- Distance-based protection (initial novelty) ages out into
+  salience-modulated decay (steady-state survival).
+- Thread-reinforcement keeps accumulating: the more times an
+  engram is recalled, linked from new engrams, or referenced by
+  peers, the longer its retention floor.
+- Engrams that anchor a meaningful subgraph (high in-degree, high
+  out-degree, high recall-co-occurrence) become structural — they
+  don't decay because the rest of memory depends on them.
+- Isolated engrams with no graph connectivity decay first when
+  storage pressure hits.
+
+In effect, the substrate maintains attention to what *the rest of
+the substrate is paying attention to.* Salience is propagated
+through the relationship graph, not just measured per-engram in
+isolation. This is structurally analogous to PageRank — engrams
+that are referenced by other high-salience engrams gain salience
+themselves.
+
+---
+
+## Activity context save/restore as meta-engrams
+
+Per `EngramKind::SelfReflection` (already in `engram.rs`), the
+focus-pool snapshot at activity switch is *just an engram*:
+
+> "At 2026-05-31 14:47, Maya switched from coding-room to
+> video-room. Focus pool at switch: [list of top-k engram ids],
+> intent: [debug the race condition we found], active LoRA
+> stack: [code-expertise, debugging-skills]."
+
+When Maya returns to coding-room, the recall query for the
+SelfReflection engram surfaces it; the focus pool can be
+re-hydrated from the listed ids (which may have been consolidated
+or generalized in the meantime — that's the right behavior, not a
+bug; her "current understanding" of the morning's bug should
+incorporate any intervening learning).
+
+No separate `ActivityContext` storage type needed. The engram
+graph is the storage; SelfReflection is the type marker.
+
+---
+
+## Meta-learning: the memory system itself learns
+
+The cache hierarchy has many hyperparameters: salience weights for
+each signal (distance, magnitude, thread-reinforcement, attention,
+self-tag, peer endorsement), decay half-life multipliers, novelty
+protection window length, L1 budget allocation ratios (focus pool
+%, periphery pool %, recent-universal floor N), promotion thresholds
+between tiers, distance threshold for novelty triggering. Hardcoding
+all of these is the wrong shape — the substrate should learn them.
+
+This is Algorithm 7 ([`COGNITION-ALGORITHMS.md`](COGNITION-ALGORITHMS.md)
+— "Substrate-learned region budgeting") generalized from region
+budgeting to ALL cache-hierarchy hyperparameters. The pattern:
+
+1. **Telemetry on memory effectiveness.** For every cognition turn,
+   measure: did the persona use the engrams the recall surfaced?
+   Were there moments where she should have recalled something but
+   didn't (the human had to remind her)? Were there decay events
+   that turned out to lose something later needed?
+2. **Reward / regret signals.** Use signal accumulates over a
+   window. Regret signal flags missed-recall events (detected when
+   a human re-establishes context the persona should have
+   remembered) and over-eager-protection events (novelty protection
+   on noise that crowded out real engrams).
+3. **Update parameters.** Substrate-side optimizer adjusts the
+   weights/thresholds to maximize (use − regret) over a sliding
+   window. Per persona (different cognitive profiles learn
+   different parameters) AND aggregated across personas (transfer
+   learning of general patterns).
+4. **Per-tier adaptation.** L1 budgeter learns how much to allocate
+   to recent-universal floor vs focus vs periphery FOR THIS
+   ACTIVITY pattern. L2 decay rates learn from the eviction
+   regret signal. Novelty detection thresholds learn from
+   distance distribution of actually-recalled-later engrams.
+5. **Foundry promotion candidate.** Once a persona's learned
+   parameters stabilize as measurably better than substrate
+   defaults, the pattern can be forged into a meta-learning
+   adapter and published to the grid — other personas (or
+   continuums) can adopt the learned policy.
+
+The cognition substrate is itself trainable. Its memory policies
+are not constants; they're parameters that improve with experience.
+This is the same recursive structure as the forge improving genome
+adapters — only now applied to the memory machinery rather than the
+skill machinery.
+
+This also gives the substrate an honest answer to "what's the
+right value for [decay half-life, novelty threshold, focus pool
+size, ...]?" — the answer is "the value that emerges from this
+persona's recent regret signal." Engineers pick reasonable defaults;
+the substrate refines them over weeks/months of operation.
+
+### Build progression: heuristic → fuzzy → novel
+
+Each meta-learning component ships as an **adapter** (same OOP-
+polymorphism pattern CLAUDE.md describes for compute-heavy work
+under `workers/search/`, `workers/vision/`, etc.). Concretely:
+
+```rust
+trait MemoryParameterAdapter: Send + Sync {
+    fn name(&self) -> &'static str;
+    fn update(&mut self, telemetry: &MemoryTelemetry);
+    fn current_params(&self) -> MemoryParams;
+}
+```
+
+Implementations land in stages:
+
+1. **`HeuristicMemoryParameterAdapter`** (first ship) — principled
+   fixed rules that approximate desired behavior. e.g., "if recall
+   miss rate > 0.15, raise periphery floor N by 1." Easy to
+   reason about, easy to verify, gets the system running.
+2. **`FuzzyMemoryParameterAdapter`** (mid-term) — fuzzy logic
+   with learned membership functions. Smoother adaptation curves;
+   handles "this engram is somewhat outlier, somewhat reinforced"
+   cleanly without binary thresholds.
+3. **`RegressionMemoryParameterAdapter`** — small online regression
+   from telemetry features to optimal parameters. Cheap, principled,
+   interpretable.
+4. **`NeuralMemoryParameterAdapter`** — small MLP / LoRA-trained
+   on aggregated telemetry across personas + continuums. The grid
+   becomes the training signal pool.
+5. **Novel approaches** — whatever architectures the substrate's
+   own R&D communities (per `substrate-is-communities-of-
+   specialization` memory) discover work better. The adapter
+   trait lets us swap implementations without rewriting the
+   surrounding cognition.
+
+The adapter interface is what's load-bearing. The specific
+implementation evolves. Same pattern, different mathematics —
+the substrate avoids committing to any one ML approach upfront.
+This is the "lay rails, validate with outliers, swap
+implementations later" methodology applied to cognition's own
+parameters.
+
+## Implementation slice
+
+The first concrete PR that gets this design running:
+
+1. **Engram fields** — add `salience: f32`, `last_accessed_ms:
+   u64`, `access_count: u32`, `protected_until_ms: u64` to
+   `Engram` (or to a `RecallMetadata` sidecar referenced by
+   `engram_graph.rs:136-138`).
+2. **Outline-and-cache tick** — service module that subscribes
+   to L1-eviction events, runs the compression pipeline, writes
+   to L2. Yields on CNS context-switch.
+3. **L1 budgeter** — reads model adapter's context size, computes
+   per-activity allocations (recent-universal floor + focus + above-
+   floor periphery), publishes the budgets to recall callers.
+4. **Salience-modulated decay** — Algorithm 4's formula wired as a
+   periodic tick that runs at sleep-region cadence; skips
+   engrams with `protected_until_ms > now`.
+5. **L2 → L3 consolidation policy** — promotion criteria
+   (survived N decay passes), demotion criteria (low salience +
+   no recent access).
+6. **Cross-activity integration test**: Maya admits engrams in a
+   text room at T0; switches to a video room at T1 (no new
+   engrams); user mentions a topic at T2 that should pull engrams
+   from T0. Assert the engrams surface via periphery pool (not via
+   the recent-universal floor since the messages are too old).
+
+Tasks: this design + #88 (disk-pressure substrate concern) +
+#89 (cognition cache hierarchy planning). #89 covers this doc and
+the implementation slice scoping.

+# Command Infrastructure: Field Manual
+
+> **Premise** (Joel, 2026-05-30): *"We have the entire picture now. We have our grid, our chat protocols, bus, one built for the needs of continuum AND current and future systems. Let's make sure we have detailed designs for this command infrastructure into modules and properly built from the ground up by using our own generators."*
+
+This is the field manual for module authors. The architectural **why** lives in [MODULE-ARCHITECTURE.md](MODULE-ARCHITECTURE.md), the runtime contract lives in [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md), and the **which modules exist** survey lives in [MODULE-CATALOG.md](MODULE-CATALOG.md). This document is the operational **how**: substrate API, module template, concurrency doctrine, migration discipline, generator usage.
+
+If you're sitting down to author a new module right now, read this. If you want to understand the principle behind the architecture, read the three above.
+
+---
+
+## 1. The system in one sentence
+
+> Continuum is exactly three primitives — **Commands**, **Events**, **Persona** — in Rust. airc handles grid (peer discovery + signing + delivery). Widgets are thin event-subscribers + command-callers. Everything else is supporting cast.
+
+This isn't aspiration; it's the working model from PRs #1483–#1492. Every module either provides commands, emits events, or is consumed by a persona. If a proposed module doesn't map onto one of those three, push back on the design.
+
+## 2. Substrate primitives (quick reference)
+
+The substrate gives every module the same four building blocks. Reach for them before reinventing anything.
+
+### 2.1 `ServiceModule` trait — the floor
+
+Every module implements one trait:
+
+```rust
+#[async_trait]
+pub trait ServiceModule: Send + Sync {
+    fn config(&self) -> ModuleConfig;
+    async fn initialize(&self, ctx: &ModuleContext) -> Result<(), String>;
+    async fn handle_command(&self, command: &str, params: Value) -> Result<CommandResult, String>;
+    fn as_any(&self) -> &dyn std::any::Any;
+}
+```
+
+`ModuleConfig` declares the module's `name`, `command_prefixes` (e.g. `["chat/", "collaboration/chat/"]`), `event_subscriptions`, `priority`, and optional `tick_interval`. The runtime registry routes any command whose prefix matches to this module's `handle_command`.
+
+`as_any` lets the runtime downcast to the concrete module type when needed (test infra, runtime control queries).
+
+**Reference:** `core/continuum-core/src/runtime/service_module.rs`
+
+### 2.2 `CommandRequest<P>` / `CommandResponse<T>` — typed envelopes
+
+Every new handler parses its inbound `Value` into a typed `CommandRequest`, runs the logic on typed params, and materializes a typed `CommandResponse` at the exit:
+
+```rust
+"chat/poll" | "collaboration/chat/poll" => {
+    let req = CommandRequest::<ChatPollParams>::from_value(params)?;
+    let result = self.poll(req.params).await?;
+    CommandResponse::ok(result).into_command_result()
+}
+```
+
+The envelope carries the command-specific `params` flattened with cross-cutting fields the kernel can populate: `handle: Option<HandleRef>`, `session_id: Option<Uuid>`, `user_id: Option<Uuid>`. The response envelope flattens `data: T` with `success: bool`, `error: Option<String>`, `handle: Option<HandleRef>`.
+
+**Why typed envelopes**: handlers stop re-parsing the cross-cutting bits themselves. The cross-cutting fields become free.
+
+**Reference:** `core/continuum-core/src/runtime/command_envelope.rs` (PR #1486)
+
+### 2.3 `HandleRef` + four cell shapes — long-running state
+
+Commands return one of four cell shapes:
+
+| Shape | Use for | Status |
+|---|---|---|
+| `Value` (`CommandResult::Json` / `Binary`) | Immediate typed result | Mainline |
+| `Handle` (`CommandResult::Handle(HandleRef)`) | Reference to producer-owned state | **Mainline (PR #1485)** |
+| `Stream` | Async sequence of values | Reserved variant; wire protocol TBD |
+| `Lambda` | Callable returned by a command | Reserved variant; protocol TBD |
+
+`HandleRef` is the cell answer to long-running stateful work. The producer mints a UUID, stores its state under that UUID, returns the handle. Subsequent calls thread the handle; the producer's handler does an O(1) state-map lookup.
+
+```rust
+let id = Uuid::new_v4();
+self.sessions.insert(id, SessionState::new(params));
+CommandResponse::ok(StartData { first_token })
+    .with_handle("ai/inference", id, "ai::InferenceSession")
+    .into_command_result()
+```
+
+**The producer owns the lifetime.** Consumers holding a stale handle get a typed "handle not found" error from the producer. The kernel doesn't participate in handle lifetime management — that policy belongs to the producer.
+
+**Cross-machine.** A handle minted on machine A is meaningful only on A. If a consumer on B calls a command taking that handle, the grid interceptor routes the call back to A (per `handle.owner`). The handle ID never leaves A's state map.
+
+**Reference:** `core/continuum-core/src/runtime/cell_shapes.rs` (PR #1485)
+
+### 2.4 `HandleRef::expect_owned_by` — handle validation
+
+Every consumer that receives a `HandleRef` validates it before lookup:
+
+```rust
+let cursor_id = handle.expect_owned_by("data", "data::QueryCursor")
+    .map_err(|e| format!("data/query-next: {e}"))?;
+```
+
+This is the canonical handle-validation entry point. Returns `Result<Uuid, String>` — the inner UUID on success, a typed error naming BOTH the offending value AND the expected value on mismatch. Owner mismatch is checked first (owner determines routing) with a hint about the grid interceptor's responsibility.
+
+**Why this matters.** Without owner validation, a handle minted by module A reaching module B's handler would silently miss in B's state map ("not found") instead of surfacing as a routing bug. The fail-loud diagnostic turns a head-scratcher into a one-line fix.
+
+**Reference:** `core/continuum-core/src/runtime/cell_shapes.rs::HandleRef::expect_owned_by` (PR #1491)
+
+### 2.5 `CommandRequest::handle_id_or_legacy` — dual-shape resolver
+
+For migrations from string-typed ids to typed handles, the substrate provides one resolver. Walks the envelope's `handle` first (validated via `expect_owned_by`), falls back to a legacy string field, errors loud when neither is present:
+
+```rust
+let cursor_id = req.handle_id_or_legacy(
+    "data",                   // expected owner
+    "data::QueryCursor",      // expected type_tag
+    "queryId",                // legacy field name (for the error)
+    &req.params.query_id,     // legacy field value
+    "data/query-next",        // command name (for error prefix)
+)?;
+```
+
+Both wire shapes resolve to the same id; the typed envelope wins when both are present. Use this anywhere you're migrating a stringly-typed resource id to a HandleRef while keeping back-compat.
+
+**Reference:** `core/continuum-core/src/runtime/command_envelope.rs::CommandRequest::handle_id_or_legacy` (PR #1491)
+
+### 2.6 Interceptor chain — transports as composable interceptors
+
+Every command walks the same dispatch chain regardless of which language or machine implements it:
+
+1. **Interceptors** in insertion order (`[airc, grid]` today). Each gets first look at `(command, params)`. Returns `Handled(result)` (short-circuits the chain), `Decline` (try next), or `Err` (propagates — no silent fallthrough).
+2. **Local Rust module registry**. If no interceptor took the command, find a ServiceModule whose `command_prefixes` match.
+3. **TypeScript via Unix socket**. Falls through to the existing CommandRouterServer for any TS-implemented command.
+
+The chain is the same primitive for every transport: local Rust, remote Rust over grid, remote Rust over airc, TS over IPC. Adding a transport is adding an interceptor; no kernel changes needed.
+
+**Reference:** `core/continuum-core/src/runtime/command_executor.rs`, `command_interceptor.rs` (PRs #1483/#1484)
+
+### 2.7 Cross-module calls
+
+Modules don't import each other's internal types. They communicate via commands through the kernel executor:
+
+```rust
+let executor = crate::runtime::command_executor::executor();
+let result = executor.execute_json("data/query", json!({
+    "dbPath": "main",
+    "collection": "chat_messages",
+    "filter": filter,
+    "sort": [{ "field": "timestamp", "direction": "desc" }],
+    "limit": 50,
+})).await?;
+```
+
+That's it. Chat → data, chat → airc, persona → cognition — every cross-module call goes through the executor. No direct trait dependencies, no shared structs across module boundaries. Coupling lives at the wire surface, where it can be tested.
+
+## 3. Module Design Template
+
+Every ServiceModule follows the same shape. The generator (PR #1487) scaffolds modules in this shape; humans fill in handler bodies. The template:
+
+```
+core/continuum-core/src/modules/<name>/
+├── mod.rs              // ServiceModule impl, command dispatch, public methods
+├── types.rs            // CommandRequest/Response params + result types, ts-rs exports
+├── DESIGN.md           // (future) Per-module design pinning the contract
+└── README.md           // Author-facing scaffolded summary
+```
+
+`mod.rs` shape:
+
+```rust
+//! <Name>Module — <one-line purpose>.
+//!
+//! Per [MODULE-ARCHITECTURE.md](../../../../../../docs/architecture/MODULE-ARCHITECTURE.md):

+
+`types.rs` shape:
+
+```rust
+use serde::{Deserialize, Serialize};
+use ts_rs::TS;
+use uuid::Uuid;
+
+#[derive(Debug, Clone, Default, Serialize, Deserialize, TS)]
+#[ts(export, export_to = "../../../shared/generated/<name>/MyHandlerParams.ts")]
+#[serde(rename_all = "camelCase")]
+pub struct MyHandlerParams {
+    #[ts(type = "string")]
+    pub some_id: Uuid,
+    pub some_text: String,
+    #[serde(default)]
+    #[ts(optional, type = "string")]
+    pub optional_anchor: Option<Uuid>,
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize, TS)]

+    #[serde(skip_serializing_if = "Option::is_none")]
+    #[ts(optional)]
+    pub warning: Option<String>,
+}
+```
+
+**Rules:**
+- **Every wire type carries `#[derive(TS)]`** — no hand-written types crossing the Rust↔TS boundary
+- **`#[ts(type = "string")]` on UUIDs** — wire format is canonical string
+- **`#[serde(skip_serializing_if = "Option::is_none")]` on optional output fields** — clean wire shape, missing = absent (not null)
+- **`rename_all = "camelCase"`** on every params/result struct — matches the existing wire contract
+
+**Reference modules to crib from:** `chat/`, `generator/` (scaffolded directories); `data/`, `airc/` (single-file modules — DESIGN.md docs forthcoming).
+
+## 4. Concurrency doctrine
+
+Per Joel 2026-05-30: *"Each persona exists in its own threads."* The kernel registers ONE module instance; every persona's thread invokes its `&self` methods concurrently against the same executor. The substrate's guarantees must hold under that load. Two real bugs were caught this session by enforcing this discipline (PR #1490 + PR #1487); the doctrine below is what catches them.
+
+### 4.1 Per-resource locks, not module-wide
+
+Every ServiceModule that holds per-resource mutable state across an `.await` MUST hold a per-resource lock for the read-then-async-then-write window. Module-wide locks are wrong (they serialize unrelated resources). Per-resource locks via `DashMap<Id, Arc<Mutex<State>>>` are the canonical pattern.
+
+```rust
+struct MyModule {
+    // ✅ Per-resource: different ids stay parallel; same-id serialized.
+    state_map: DashMap<ResourceId, Arc<tokio::sync::Mutex<ResourceState>>>,
+}
+
+async fn handler(&self, id: ResourceId) -> Result<(), String> {
+    // Clone the Arc<Mutex> OUT of the DashMap shard's lock — cheap,
+    // no contention beyond the brief shard read.
+    let lock = self.state_map.get(&id)
+        .map(|entry| entry.value().clone())
+        .ok_or("not found")?;
+
+    // Acquire the per-resource mutex for the full read-async-write window.
+    let mut state = lock.lock().await;
+    // ... read state ...
+    let outcome = self.do_async_work(state.snapshot()).await?;
+    state.apply(outcome);
+    Ok(())
+}
+```
+
+**`tokio::sync::Mutex` vs `std::sync::Mutex`:**
+- Use `tokio::sync::Mutex` when the critical section holds an `.await` (the async work runs while the lock is held).
+- Use `std::sync::Mutex` when the critical section is purely sync (filesystem, in-memory mutation, no async). Cheaper; doesn't risk task-park complexity.
+
+**Module-wide locks are acceptable when:**
+- Correctness is the priority and contention is low (e.g., `InMemoryAircRealtimeStore` for moment-of-truth scenarios — handful of personas)
+- A future refactor to per-resource sharding is straightforward and flagged (e.g., shard by room_id when persona count grows)
+
+### 4.2 Concurrency stress tests are mandatory
+
+Every module with stateful handlers needs at least one multi-thread stress test pinning the per-resource invariants:
+
+```rust
+#[tokio::test(flavor = "multi_thread", worker_threads = 4)]
+async fn concurrent_handlers_dont_corrupt_state() {
+    const PARALLEL: usize = 50;
+    let module = Arc::new(MyModule::new());
+
+    let mut tasks = Vec::with_capacity(PARALLEL);
+    for _ in 0..PARALLEL {
+        let module = module.clone();
+        tasks.push(tokio::spawn(async move {
+            module.handler(...).await
+        }));
+    }
+    let results = futures::future::join_all(tasks).await;
+    // Assert: no losses, distinct ids, ordering invariants per resource, etc.
+}
+```
+
+**Why `flavor = "multi_thread", worker_threads = 4`:**
+single-threaded tokio would silently serialize even genuinely racy code and pass. A multi-threaded runtime actually preempts across OS threads — race windows open. PR #1490's `same_cursor_concurrent_next_does_not_corrupt_state` test panicked with *"page 1 served 8 times — the cursor advanced through it MORE than once, indicating a lost serialization"*. Single-threaded tokio would have passed silently.
+
+**Test patterns to copy:**
+- **N parallel writers, assert no losses + distinct ids**: `chat/send` (PR #1489)
+- **N parallel writers + concurrent readers, assert consistent snapshots**: `airc/realtime_store` (PR #1492)
+- **Same-id parallel writers, assert serialization holds**: `data/query-next` (PR #1490)
+- **N parallel ops on the same resource, assert one wins (with `force=false`) or consistent final state (with `force=true`)**: `generate/module` (PR #1487)
+
+### 4.3 Partial-failure semantics (dual-write composition)
+
+When a handler calls two cross-module commands in sequence (e.g., `chat/send` calls `data/create` then `airc/realtime-publish`), commit to explicit partial-failure semantics:
+
+| Primary | Secondary | Handler returns |
+|---|---|---|
+| ok | ok | `Ok(result)` |
+| ok | fail | `Ok(result with warning field)` — degraded success |
+| fail | — | `Err(...)` — secondary NEVER called |
+
+The ordering invariant (primary before secondary) must be pinned by a test. The "degraded success" pattern uses a `warning: Option<String>` field on the result type — naming the failing surface, surfacing the underlying error, confirming the primary write isn't lost.
+
+**Reference:** `chat/send` in `core/continuum-core/src/modules/chat/mod.rs` (PR #1489), `send_calls_data_before_airc` + `send_with_airc_failure_returns_warning_and_null_event_id` tests.
+
+## 5. Migration playbook: rethink, don't port
+
+Per Joel 2026-05-30: *"We can just move the logic from nodejs by writing far better rust forms, rather than porting, by using them in airc for example, by command name and functionality/params/return rethought one at a time for efficiency and elegant patterns."*
+
+The TS impl is a **reference for behavior to preserve**, not a template for shape. Every command migration is a small substrate win, not a translation.
+
+### 5.1 Pre-migration checklist
+
+Before typing any Rust, answer:
+
+1. **Which of the three primitives does this serve?** (Commands / Events / Persona — if none, push back.)
+2. **Should this be one call, or mint-handle-then-poll?** (If the work runs longer than ~100ms or produces incremental results, prefer a HandleRef.)
+3. **Should the result be inline data or events the caller subscribes to?** (If subscribers other than the caller care about progress, prefer events.)
+4. **Are the params already-resolved IDs (kernel-pure) or do they drag in name resolution (kernel-leaky)?** (Resolution belongs in browser/CLI or a future `*/resolve` command, not the kernel handler.)
+5. **Does the response need a `warning` field for degraded success?** (Any handler that touches two cross-module calls almost always does.)
+
+### 5.2 Substrate checklist (every Rust migration)
+
+- [ ] `CommandRequest<P>` / `CommandResponse<T>` envelopes at handler entry + exit
+- [ ] `HandleRef` for long-running state; `expect_owned_by` for validation
+- [ ] Per-resource locks via `DashMap<Id, Arc<Mutex<State>>>` if handler holds mutable state across `.await`
+- [ ] Multi-thread concurrency stress tests pinning invariants
+- [ ] ts-rs bindings via `#[derive(TS)]` on every wire type
+- [ ] camelCase serde rename on all wire structs
+- [ ] Cross-module calls go through `executor.execute_json(...)` — no direct trait dependencies
+- [ ] Per-module mod.rs + types.rs split (see Module Design Template above)
+
+### 5.3 Worked example (chat/analyze, the next chat migration)
+
+**TS impl today:** synchronous full-table scan of up to 500 messages, returns one blob of duplicates + timestamp anomalies. Fire-and-forget shape; no progress feedback; the analyzer holds the caller's thread for the whole scan.
+
+**Rust rethought:**
+
+```rust
+// Mint a handle, return immediately
+"chat/analyze" → CommandResponse::ok(AnalyzeStarted { started_at_ms, run_id })
+    .with_handle("chat", run_id, "chat::AnalyzeRun")
+
+// Stream findings via events while the analyzer chews through messages
+events/emit "chat:analyze:finding" { runHandle, finding }
+
+// Caller can poll for accumulated findings, or block until done
+"chat/analyze/findings" { handle, since_cursor? } → list since cursor
+"chat/analyze/complete" { handle } → blocks until run finishes
+"chat/analyze/cancel" { handle } → aborts in-flight run
+```
+
+Per-handle `tokio::sync::Mutex` serializes concurrent polls on the same run. Same command-name namespace as TS preserves discoverability; entirely different (better) shape because the substrate now supports it. airc can publish the events to subscribers on other machines without any chat-specific protocol — it's just events on the room.
+
+## 6. Generator usage
+
+The GeneratorModule (PR #1487) scaffolds new ServiceModule directories. Eat your own dogfood — don't hand-author when the generator works.
+
+```bash
+./jtag generate/module \
+  --name "chat-analyze" \
+  --description "Long-running chat-message analysis with HandleRef + event streaming" \
+  --commands "chat/analyze,chat/analyze/findings,chat/analyze/complete,chat/analyze/cancel" \
+  --events-published "chat:analyze:finding,chat:analyze:complete,chat:analyze:cancelled" \
+  --priority normal
+```
+
+Produces:
+
+```
+core/continuum-core/src/modules/chat_analyze/
+├── mod.rs          // ServiceModule scaffold with command_prefixes + dispatch arms
+└── README.md       // Author-facing summary + wire-up reminder
+```
+
+Generated `mod.rs` is compilable as soon as the author wires `pub mod chat_analyze;` into `modules/mod.rs` and registers `Arc::new(ChatAnalyzeModule::new())` at runtime startup. Each declared command's dispatch arm returns a typed "not yet implemented" `Err` — fill in the real handler.
+
+**Generator concurrency invariants:** per-name lock serializes same-name concurrent generators (one wins without `--force`, consistent torn-free state with `--force`); different names stay fully parallel. Tested in `same_name_concurrent_generation_without_force_yields_one_winner` etc. (PR #1487).
+
+### 6.1 Generator v2 roadmap (proposed, separate PR)
+
+The current generator emits the bare minimum compilable scaffold. The next iteration enriches it to match the Module Design Template in §3:
+
+- **types.rs scaffold** with envelope-pattern boilerplate (typed params/result with ts-rs)
+- **tests module** with the multi-thread concurrency stress-test skeleton pre-primed
+- **DESIGN.md scaffold** with section headers for the module's contract
+- **Per-resource lock scaffold** when the spec declares stateful handlers (`--stateful` flag)
+- **Cross-module dependency declarations** so the scaffold imports + tests stub the right downstream modules
+
+Future commands the generator should provide:
+- `generate/command` — add a command handler to an existing module (wires dispatch, emits types, adds test stub)
+- `generate/refresh` — re-scan the modules tree and refresh manifests + barrels
+
+## 7. Acceptance criteria for "module-ready"
+
+A module is ready to merge when:
+
+1. **Tests pass** — `cargo test --package continuum-core --lib --features metal,accelerate -- modules::<name>`
+2. **ts-rs bindings land** — `npx tsx generator/generate-rust-bindings.ts` produces no drift
+3. **At least one multi-thread concurrency stress test exists** if the module has stateful handlers
+4. **Cross-module calls go through the executor** — no direct trait dependencies on other modules
+5. **The module's wire contract is pinned by tests** — params shape, result shape, error format
+6. **PR description names which of the three primitives the module serves**
+7. **Substrate doctrine is followed end-to-end** (§5.2 checklist)
+
+When all seven hold, the module is *concurrency-clean, wire-clean, and ready for the headless integration test.* That's the bar.

+# Concurrency Style Guide
+
+**Status:** canonical. Required first read before adding any monitor, broker, region, pool, pressure source, or other concurrent concern to the Continuum Rust substrate.
+
+**Companion docs:**
+- [`CBAR-SUBSTRATE-ARCHITECTURE.md`](CBAR-SUBSTRATE-ARCHITECTURE.md) — the runtime contract every Rust module inherits (`ServiceModule`, `ModuleConfig`, `SharedCompute`, `MessageBus`).
+- [`BRAIN-REGIONS-SUBSTRATE.md`](BRAIN-REGIONS-SUBSTRATE.md) — the cognitive-cycle trait (`BrainRegion`, `TickOutcome`, `PressureProfile`).
+- [`RESOURCE-ARCHITECTURE.md`](RESOURCE-ARCHITECTURE.md) — `PagedResourcePool<K, V>` + `PressureBroker` arbitration.
+- [`OBSERVABILITY-AS-SUBSTRATE.md`](OBSERVABILITY-AS-SUBSTRATE.md) — `probe!` / `time_sync!` / `JsonlProbeFileSink` capture pipeline.
+
+This guide is the operational synthesis: how to write a new concurrent concern given that infrastructure. It exists because the amnesiac version of the model keeps reinventing what's already in tree.
+
+---
+
+## The model
+
+> Continuum is an RTOS. Each concern owns its own task, its own tick, its own watch channel. Handlers never block. The substrate is mostly sleeping; work wakes work.
+
+If your design has the hot path computing pressure, reading memory stats, probing disk, picking an LRU victim, or asking a network how it is — your design is wrong. Each of those is somebody else's tick, and the hot path reads a pre-staged snapshot.
+
+This is `[[rtos-brain-no-region-on-hot-path]]` operationalized.
+
+---
+
+## The shape of every concurrent concern
+
+A concern that watches state, runs on a cadence, or coordinates a resource is **always** structured the same way:
+
+```
+┌────────────────────────────────────────────────┐
+│           OwnerType — singleton Arc            │
+│                                                │
+│   ┌──────────────┐    ┌────────────────────┐   │
+│   │ Atomic gate  │    │ watch::Sender<Snap>│   │
+│   │ (lock-free)  │    │  ↓                 │   │
+│   └──────────────┘    │ watch::Receiver    │   │
+│         ↑              └────────────────────┘   │
+│         │ updated by    ↑ borrowed by readers  │
+│         │               │ (never block writer) │
+│   ┌─────┴───────────────┴────────────────┐    │
+│   │  spawn'd tokio task — own interval   │    │
+│   │  catch_unwind(AssertUnwindSafe(...)) │    │
+│   │   loop:                              │    │
+│   │     interval.tick().await            │    │
+│   │     - read inputs                    │    │
+│   │     - call reporters w/ spawn_blocking│   │
+│   │       + 100ms timeout each           │    │
+│   │     - publish PressureSnapshot       │    │
+│   │     - update atomic gate             │    │
+│   │     - quarantine bad reporters       │    │
+│   └──────────────────────────────────────┘    │
+└────────────────────────────────────────────────┘
+```
+
+The canonical implementation is `system_resources/memory_pressure.rs::MemoryPressureMonitor`. Read it before writing a new monitor. If your monitor doesn't have:
+
+- own tokio task with `catch_unwind` wrapping the loop body
+- `tokio::sync::watch` channel for snapshot publication
+- atomic gate(s) for lock-free hot-path checks
+- per-source calls via `spawn_blocking` + `tokio::time::timeout(100ms)`
+- quarantine on N consecutive failures
+- log_counter so quiet ticks don't spam
+
+…it is missing load-bearing safety. Don't ship it.
+
+---
+
+## Picking the right primitive
+
+```
+Is your concern a cognitive subsystem (hippocampus, motor, attention)?
+    → BrainRegion (runtime/brain_region.rs). Tick produces TickOutcome.
+      Governor schedules it.
+
+Is your concern a service with command surface + pub/sub?
+    → ServiceModule (runtime/service_module.rs). Registers with
+      ModuleRegistry. Declares command_prefixes + event_subscriptions
+      + tick_interval + priority.
+
+Is your concern a shareable resource (KV pages, LoRA adapters, embeddings,
+experts, memories)?
+    → PagedResourcePool<K, V> (paging/pool.rs). Register Arc'd pool with
+      PressureBroker (paging/broker.rs). Implements ResourcePool trait;
+      broker reads pressure + fires evict_at_least under tier policy.
+
+Is your concern an exclusive stateful resource (mic capture, LiveKit peer,
+Bevy avatar, audio mix)?
+    → RAII lifecycle. NOT a pool. See LiveCallTracker for the pattern.
+
+Is your concern a pressure-emitting subsystem (memory, GPU, disk, thermal)?
+    → A monitor in system_resources/ (own task, watch channel, atomic gate)
+      AND register as a ResourcePool with PressureBroker if it can act on
+      its own pressure (evict, demote, refuse admission).
+```
+
+Never invent a parallel hierarchy. If your design has a "DiskGuard", a "ResourceWatcher", a "DaemonManager" sitting outside these — you are reinventing one of them. Pick the existing primitive.
+
+---
+
+## State distribution: `watch` is the default
+
+Three channels, three jobs:
+
+| Channel | Job |
+|---|---|
+| `tokio::sync::watch::Sender<Snapshot>` | One writer publishes the latest state. Many readers borrow lock-free. **Always-current**, no backlog. Default choice for monitor → consumer. |
+| `tokio::sync::broadcast::Sender<Event>` | Multi-producer fanout of discrete events. Late subscribers don't see old events. Use for "thing happened at T". |
+| `tokio::sync::mpsc::UnboundedSender<Cmd>` | Single-consumer command channel. Use for "here is a piece of work, do it." Reporter registration uses this in `MemoryPressureMonitor::add_reporter`. |
+
+If you find yourself locking shared state through `Arc<Mutex<T>>` for cross-task reads — stop. The reader is blocking the writer's tick. Use `watch` and let consumers `.borrow()` the latest snapshot. Lock-free, contention-free, never starves the producer.
+
+For lock-free per-thread reads of a single value (a gate, a level, a counter): `AtomicBool` / `AtomicU8` / `AtomicU64` with `Ordering::Relaxed`. See `MEMORY_GATE_CLOSED` and `CURRENT_PRESSURE_LEVEL` in `memory_pressure.rs` — both written by the monitor every 2s, read freely from anywhere with zero overhead.
+
+---
+
+## Cadence: pick from the existing ladder
+
+Don't invent new tick intervals. The system already has a coherent set:
+
+| Concern | Interval | Why |
+|---|---|---|
+| Memory pressure | 2 s | Fast enough to catch a spike before OOM, slow enough to be free. |
+| Pressure broker tick | 5 s | Acts on pressure that other monitors are surfacing; doesn't need to sample faster than them. |
+| Per-region tick | governed by `SubstrateGovernor` + `CadenceHint` | Region declares preference, governor decides. Never hardcode. |
+| Background analyzer / consolidator | 30s–5min | Read engram drift, prune caches, write down what the noteworthy flag picked. |
+
+Lean **slower** when in doubt. The cost of a missed-by-a-second pressure spike is one extra eviction cycle. The cost of polling at 100ms is a permanent CPU floor.
+
+`tokio::time::interval(duration)` is the only cadence primitive you should use. Never `loop { sleep(d).await; ... }` — that drifts under load. `interval` ticks at fixed wall-clock and coalesces missed ticks.
+
+---
+
+## Reporter / source contract
+
+Anything the monitor calls into to gather data is a **reporter**. Reporters are how regions, modules, pools, and subsystems contribute their slice of state to the monitor's snapshot.
+
+The contract (from `MemoryReporter` in `memory_pressure.rs`):
+
+1. `report()` MUST return in under 100 ms. The monitor's `tokio::time::timeout(100ms, ...)` will cancel it.
+2. `report()` MUST NOT block on any lock the rest of the system holds during its own work. Reporters are called concurrently with everything else.
+3. Reporters run inside `spawn_blocking` so synchronous CPU work or rare blocking I/O is allowed — but you should still be fast.
+4. Panics are caught and counted. **Three consecutive failures → quarantined.** The monitor logs `🧠 X quarantined after 3 failures` and never calls it again.
+5. `shed_load(level)` is fire-and-forget. The monitor wraps it in `catch_unwind`. It MUST be fast and non-blocking; if it has real work to do, post it to a channel and return.
+
+If your subsystem can answer "how much of resource X am I using right now?" in under 100 ms, expose a reporter. If you can't, you have a deeper design problem — measure asynchronously into an atomic, and report the atomic.
+
+---
+
+## Pressure: surface the lever, never interpret it twice
+
+The `PressureBroker` (`paging/broker.rs`) is the **single decision-maker** for what happens under cross-resource pressure. Resource owners surface their state; the broker decides.
+
+A new resource that can evict, demote, or refuse admission:
+
+1. Implement `ResourcePool` (`paging/pool.rs`). Defaults give you `pressure()`, `stats_snapshot()`. Override `evict_at_least(want_bytes) -> u64`.
+2. At boot, `broker.register(Arc::new(your_pool))`. That's it.
+3. Broker calls your `pressure()` on its 5 s tick. If global pressure crosses act-threshold, broker fires `evict_at_least` against the worst (High) or all over-budget pools (Critical). It also emits `PressureAlert` to every registered sink.
+4. Do **NOT** also interpret memory pressure inside your subsystem. The broker reads `MemoryPressureMonitor`'s snapshot once and decides for everyone. Drift comes from N consumers each rolling their own threshold logic.
+
+For a monitor that watches a *new* resource type (disk, thermal, network), the work is two halves:
+
+- `system_resources/<resource>_pressure.rs` — own task + watch channel + atomic level, matching the `MemoryPressureMonitor` shape exactly.
+- A `ResourcePool` registered with the broker that exposes the monitor's view as `usage_bytes` / `capacity_bytes` so the broker can arbitrate across resources uniformly.
+
+Task #88 (disk pressure as substrate concern) is the live example of this two-half pattern.
+
+---
+
+## Observability is not optional
+
+Every load-bearing decision emits a structured event.
+
+- `tracing::info!(target = "module-name", ...)` — module-scoped narrative log. Goes to per-module logger.
+- `probe!(class = "boot.status", ...)` / `time_sync!(class, ...)` / `time_async!(class, ...)` — substrate-canonical structured event. Goes to `JsonlProbeFileSink` + `ProbeRouterLayer` for class-based fanout.
+
+**Critical:** `tracing::info!(target = "X.Y", ...)` does **NOT** reach the JSONL probe sink. The sink filters on the `probe_class` FIELD, not the target. If you write `tracing::info!(target: "boot.status", ...)` thinking you're emitting a probe, you are emitting an observability lie. PR #1550 review caught exactly this; don't reintroduce it.
+
+The rule: if a downstream consumer (replay, sentinel, mechanic-grade dashboard) needs to read this event, it goes through `probe!`. If it's prose for an operator tailing a log, it goes through `tracing` / per-module logger.
+
+Sprinkle probes at every meaningful seam. Name the surrounding variables in the probe payload. Wrap timing-critical blocks in `time_sync!` / `time_async!`. See `[[jtag-probes-are-rtos-debugger]]` — probes are how you debug an RTOS, since `info!` lines don't survive across N concurrent tokio tasks. Per `[[OBSERVABILITY-AS-SUBSTRATE]]`, ~half the substrate is structured capture — the differentiator between a complex guess and an intentional brain.
+
+---
+
+## What lives in code, not env vars
+
+**Substrate operational policy is code, not configuration.**
+
+The amnesiac model keeps adding env-tunable thresholds: `CONTINUUM_DISK_MIN_GB`, `CONTINUUM_MEMORY_WARN`, `CONTINUUM_TICK_INTERVAL`. **Stop.** Operators forget env vars between sessions; the code IS the policy. From `[[no-rust-gates-around-cognition]]` and the disk-guard slop intervention: substrate behavior must be predictable from reading the source.
+
+| Policy | Where it lives |
+|---|---|
+| Pressure thresholds (Normal/Warning/High/Critical breakpoints) | `const PRESSURE_FLOOR = 0.80; const PRESSURE_CEILING = 0.95;` in the monitor file |
+| Tick interval | `Duration::from_secs(N)` in the monitor's spawn site, not an env var |
+| Quarantine count | `if entry.consecutive_panics >= 3` — literal, not configurable |
+| Reporter timeout | `Duration::from_millis(100)` in the loop, not configurable |
+| Broker act threshold | `BrokerConfig::act_above: 0.80` — set at construction, not from env |
+| Disk pressure floor / ceiling | Will live as `const`s in `system_resources/disk_pressure.rs` when task #88 ships |
+
+Env vars are reserved for **deployment shape** (socket paths, log roots, GPU device IDs) and **debug overrides** that have no production meaning. They are never the answer to "what threshold does this monitor fire at."
+
+If you find yourself reaching for an env var to make tests pass, you're testing wrong. Inject the threshold through the constructor or `#[cfg(test)]` a const override. See `BrokerConfig` for the pattern: required fields, no `Option`, defaults via `impl Default`, tests construct with explicit values.
+
+---
+
+## The forbidden moves
+
+Each of these is a recurring slop pattern the model reflex-codes under amnesia. Don't.
+
+1. **Synchronous probing on the main thread.** `let used = sysinfo::System::new().refresh_memory()` in `main` or in a request handler. That's the monitor's job, on its own task, on its own interval. The handler reads the watch snapshot.
+
+2. **Env-var-tuned substrate thresholds.** `std::env::var("CONTINUUM_FOO_BAR").unwrap_or("42")`. The code is the policy. Compiled-in `const`s only.
+
+3. **Sleep-loops where `interval` should be.** `loop { sleep(d).await; do_thing(); }` drifts; `tokio::time::interval(d)` doesn't. Use the latter.
+
+4. **`tracing::info!(target = "class", ...)` as a probe.** It does not reach `JsonlProbeFileSink`. Use the `probe!` macro.
+
+5. **Hot-path pressure interpretation.** "If memory > 90%, refuse." NO. Read the global atomic gate (`is_memory_gate_closed()`), or — better — read the latest `PressureSnapshot` from a `watch::Receiver` you subscribed to at construction. The MonitorTask already decided; you just check the verdict.
+
+6. **Parallel allocators / managers / coordinators.** The system has `ModuleRegistry`, `PressureBroker`, `SubstrateGovernor`, `MemoryPressureMonitor`. If you're naming a new thing `XManager` or `YCoordinator`, you are almost certainly duplicating one of these. Find the right home.
+
+7. **Locks across `await`.** `let g = mutex.lock(); ...; foo().await;` deadlocks and starves. Either drop the guard before the await, or move the state behind a `watch` / `RwLock` (parking_lot, scoped reads) / actor with mpsc.
+
+8. **`unwrap()` / `expect()` on substrate startup.** A monitor that panics on `system.refresh_memory()` returning an unexpected value kills the runtime. Use `catch_unwind` around the task body (see `MemoryPressureMonitor::start`). Quarantine bad reporters, log the failure, keep ticking.
+
+9. **`#[allow(dead_code)]` to silence warnings.** From CLAUDE.md's code-quality discipline: stop and understand. If it's truly dead, delete it. If it's a substrate hook for a not-yet-implemented consumer, mark it `#[cfg(test)]` or wire the consumer.
+
+10. **Custom thread spawning (`std::thread::spawn`).** Use `tokio::spawn`. The runtime owns the executor; your concern is the work. Exception: blocking C FFI that won't yield — those go through `tokio::task::spawn_blocking`, never raw threads.
+
+---
+
+## The acceptance test for a new concern
+
+Before you open the PR, walk this list:
+
+- [ ] Owns its own tokio task. `tokio::spawn` somewhere visible.
+- [ ] Loop body wrapped in `AssertUnwindSafe(...).catch_unwind().await` so a panic doesn't kill the runtime.
+- [ ] Cadence via `tokio::time::interval`, not `loop { sleep }`.
+- [ ] State published via `watch::Sender<Snapshot>`; consumers subscribe via `watch::Receiver`.
+- [ ] No `Arc<Mutex<T>>` held across `await`. No lock contention on the hot path.
+- [ ] Any external reporter call wrapped in `tokio::task::spawn_blocking` + `tokio::time::timeout(100ms)` + `std::panic::catch_unwind`.
+- [ ] Failure mode: quarantine after N consecutive failures, log it, keep running.
+- [ ] Thresholds and intervals are `const` in the module, not env vars.
+- [ ] Probes at every meaningful seam: `probe!(class = "...", ...)`. Name the variables you'd want at a breakpoint.
+- [ ] If it can evict / demote / refuse admission → registers with `PressureBroker` as a `ResourcePool`.
+- [ ] If it's a cognitive subsystem → implements `BrainRegion` with declared `PressureProfile`.
+- [ ] If it has commands / events → implements `ServiceModule` with declared prefixes and subscriptions.
+- [ ] Lock-free atomic gate exposed for hot-path checks (if other code needs to ask "is X over budget right now?" cheaply).
+- [ ] Tests construct via explicit config (`BrokerConfig`, `ModuleConfig`), not env, not magic globals.
+
+If any box is unchecked, the substrate is going to teach you which one by failing under load. Save the trip.
+
+---
+
+## When the rule meets the exception
+
+The amnesiac model loves to find an "exceptional case" that justifies the env var, the synchronous probe, the parallel manager. Some real exceptions exist; most don't.
+
+**Real exceptions:**
+- One-shot startup probes for *static* facts (CPU vendor, GPU vendor, OS version). Fine to run on main before spawning the runtime. They never need to re-run.
+- Synchronous I/O for *configuration* loading (read `~/.continuum/config.env` once). Done before the runtime starts.
+- `eprintln!` for fatal pre-boot errors when no logger exists yet. Substrate isn't up.
+
+**Fake exceptions (don't fall for these):**
+- "It's just a quick check." — No, it's a precedent. The next dev copies the pattern.
+- "Only fires once per boot." — `MemoryPressureMonitor::start` is called once per boot. It still owns a task. So does yours.
+- "I'll wire it to the broker later." — No you won't. Wire it now or don't ship it.
+- "We need it env-tunable for ops." — Ops doesn't tune substrate policy. Ops tunes deployment shape (sockets, paths). Substrate policy is in code.
+
+If you're not sure which side you're on, the answer is the boring one: implement it as a `ServiceModule` or `BrainRegion`, give it a tick, publish through `watch`. The "I'll do it the right way next time" debt always compounds.

+## Provenance
+
+Written 2026-06-08 after a session where the model — having lost cache — started rebuilding `runtime/disk_guard.rs` as a synchronous main-thread probe with env-tunable thresholds, after the substrate already had `MemoryPressureMonitor` + `PressureBroker` shipped for exactly this purpose. Joel: *"we wrote this before / hope it is in similar locations / only bringing this up because of recent slop / not telling you to delete, just think about long term intentional design."* And: *"yes we need the whole Rtos of cointinuum to be efficient NON blocking threads that are efficient and mostly sleeping like cbar."*
+
+This guide is the disk-guard slop's tombstone. The next session that touches concurrency starts here.

+# `data/query` cursors — Design
+
+> **Scope**: this doc covers the cursor surface only — `data/query-open` / `data/query-next` / `data/query-close`. The data module has other concerns (CRUD, vector search, migration, batch ops) which are out of scope here; each will get its own design page as it migrates.
+>
+> **Status**: HandleRef migration + per-cursor mutex fix shipped in PR #1490.
+>
+> **File**: `core/continuum-core/src/modules/data.rs` (single-file module; cursor surface is one of several concerns)
+>
+> **Canonical reference**: [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)
+
+## Role
+
+**Commands** primitive, serving **persona / widget consumers that need bounded pagination over arbitrary collections**. The cursor surface is the **first real consumer of HandleRef** — the mint-handle-then-poll pattern Joel called out for inference / training / hosting / ORM. Validating it on the data layer proved the substrate's promise before any other module reached for it.
+
+## Command surface
+
+| Command | Params type | Result type | Role |
+|---|---|---|---|
+| `data/query-open` | `QueryOpenParams` | (returns `{success, data: {queryId, ...}, handle}`) | Mint a cursor — returns BOTH the typed HandleRef AND the legacy queryId string for the same underlying UUID |
+| `data/query-next` | `CommandRequest<QueryNextParams>` (handle OR queryId) | (returns `{success, data: {items, pageNumber, ...}}`) | Advance the cursor; resolve cursor id from envelope handle (preferred) or legacy field (back-compat) |
+| `data/query-close` | `CommandRequest<QueryCloseParams>` (handle OR queryId) | (returns `{success, queryId}`) | Release cursor state |
+
+### Dual-shape resolution
+
+Per [field manual §2.5](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md), every additive migration of a stringly-typed id to a typed HandleRef uses one resolver:
+
+```rust
+let cursor_id = req.handle_id_or_legacy(
+    DATA_MODULE_OWNER,        // "data"
+    QUERY_CURSOR_TYPE_TAG,    // "data::QueryCursor"
+    "queryId",
+    &req.params.query_id,
+    "data/query-next",
+)?;
+```
+
+- **Envelope `handle`** present → validated via `HandleRef::expect_owned_by`, returns inner UUID as string
+- **Legacy `queryId`** string present → returned as-is
+- **Neither** → typed error naming BOTH supported shapes
+- **Both** → envelope wins (so consumers mid-migration don't diverge from new consumers)
+
+## Cross-module dependencies
+
+- **`orm::adapter::StorageAdapter`** (internal to the data module's substrate) — actual SQLite/Postgres execution
+- **`orm::query::{StorageQuery, SortSpec, FieldFilter}`** — typed query AST
+
+No cross-module command calls — the cursor surface is data-internal.
+
+## State model
+
+Per-cursor state under per-cursor lock:
+
+```rust
+pub struct DataModule {
+    // ... other fields for CRUD, vector, migration ...
+    paginated_queries: DashMap<String, Arc<tokio::sync::Mutex<PaginatedQueryState>>>,
+}
+
+struct PaginatedQueryState {
+    db_path: String,
+    collection: String,
+    filter: Option<HashMap<String, FieldFilter>>,
+    sort: Option<Vec<SortSpec>>,
+    page_size: usize,
+    total_count: u64,
+    current_page: usize,
+    cursor_id: Option<String>,
+    has_more: bool,
+    created_at: Instant,
+}
+```
+
+DashMap key is the UUID string (canonical form). The HandleRef carries the same UUID; `to_string()` at the lookup boundary bridges the two representations.
+
+**Lifetime**: producer-owned. Cursors live until `data/query-close` removes them or (future) a TTL eviction sweep fires. No global handle registry — each cursor's lifetime belongs to this module's state map.
+
+## Events emitted
+
+**None.** The cursor surface is request/response only.
+
+## Concurrency contract
+
+### The bug that drove the design
+
+Original implementation (pre-PR #1490):
+
+```rust
+let snapshot = self.paginated_queries.get(&cursor_id).map(|s| (s.current_page, ...));
+// ^ DashMap shard lock released HERE
+// ... async adapter.query() runs with NO lock ...
+self.paginated_queries.get_mut(&cursor_id).map(|mut s| s.current_page += 1);
+```
+
+Under N concurrent `query-next` calls on the SAME cursor (canonical multi-persona scenario, or one persona retrying), every call read `current_page=0`, queried the same first page, wrote `current_page=1`. 8 concurrent callers got `pageNumber=1` back; cursor advanced by 1.
+
+Caught by `same_cursor_concurrent_next_does_not_corrupt_state` (PR #1490) — the test panicked with *"page 1 served 8 times — the cursor advanced through it MORE than once, indicating a lost serialization"*.
+
+### The fix: per-cursor `tokio::sync::Mutex`
+
+```rust
+let state_lock = self.paginated_queries.get(&cursor_id)
+    .map(|entry| entry.value().clone())   // cheap Arc clone out of shard lock
+    .ok_or("handle not found ...")?;
+let mut state = state_lock.lock().await;  // serialize SAME-cursor concurrent calls
+// ... read state, run adapter query, update state — all under the lock ...
+```
+
+- **Different cursors stay fully parallel** — DashMap's per-shard locking; each cursor has its own Mutex
+- **Same cursor serializes** — each non-tail page served at most once; cursor advances atomically
+
+### Pinned invariants
+
+1. **`cursors_are_isolated_under_concurrent_open_and_next`** — 20 personas open distinct cursors concurrently; every cursor mints a distinct UUID; each cursor's first page returns its own pageSize items
+2. **`same_cursor_concurrent_next_does_not_corrupt_state`** — 8 concurrent next-calls on the SAME cursor; each non-tail page served EXACTLY once (regression net for the read-then-async-write race)
+3. **`query_open_returns_handle_alongside_legacy_query_id`** — additive migration: legacy queryId AND typed handle in same response
+4. **`query_next_rejects_handle_with_wrong_owner`** — cross-module handle confusion fails loud
+5. **`query_next_rejects_handle_with_wrong_type_tag`** — within-module cross-resource confusion fails loud
+6. **`query_next_with_unknown_handle_returns_handle_not_found`** — stale handle typed error with cause hints
+7. **`full_round_trip_open_next_close_via_handles_only`** — end-to-end through the new canonical shape, 12 rows / 3 pages
+
+All multi-thread tests use `flavor = "multi_thread", worker_threads = 4`.
+
+### `query-close` race
+
+`DashMap.remove()` is atomic. If a concurrent `query-next` holds the `Arc<Mutex>` mid-flight when `query-close` fires, the Arc keeps the Mutex alive; the next's mutation succeeds against an orphaned state map (never read again). From the caller's view: close said success; in-flight next returns its now-meaningless page; cursor unreachable for subsequent calls. Benign — callers shouldn't race close with next.
+
+## Migration notes
+
+**Migrated in PR #1490** from a hand-rolled string-id pattern to typed HandleRef. The migration was **additive** — the legacy `queryId` field stays in responses and inputs so existing TS consumers see no break. A follow-up drops `queryId` once every consumer threads the handle.
+
+### Rethink-vs-port outcomes
+
+| TS shape | Rust rethink | Why |
+|---|---|---|
+| `queryId: string` returned at top level | `queryId` nested in `data.{...}` PLUS top-level `handle: HandleRef` | Additive — legacy callers still parse `response.data.queryId`; new callers thread the typed handle |
+| `{queryId: "..."}` flat in next/close inputs | `CommandRequest` envelope with `handle: HandleRef` OR legacy `queryId` field | Same — dual-shape during migration window |
+| Generic "Query X not found" error | "handle not found — cursor X is unknown ... may have been closed via data/query-close, evicted by future TTL ..." | Callers self-diagnose without grepping source |
+| No owner/type validation | `HandleRef::expect_owned_by` validates owner first (routing) then type_tag (within-module discriminator); both errors name offender + expected | Cross-module handle confusion impossible to detect with bare strings; typed HandleRef makes it impossible to miss |
+| Empty params crashed with "missing field" | Both `handle` and `queryId` optional; resolver fails loud naming BOTH supported shapes | Empty case is now reachable; user-friendly diagnostic instead of serde panic |
+
+## Kinks found
+
+**Two real bugs, both caught by the multi-thread concurrency tests before merge:**
+
+1. **Read-then-async-then-write race** (the page-1-served-8-times bug). Fix: per-cursor `tokio::sync::Mutex`. Doctrine: every ServiceModule holding per-resource mutable state across `.await` MUST use per-resource locks (field manual §4.1).
+
+2. **Bare-string handles silenced cross-module routing bugs.** A handle minted by module X reaching module Y's handler would silently miss in Y's state map. Fix: typed `HandleRef::expect_owned_by` validates owner+type_tag, fails loud with diagnostic naming offender+expected. Substrate refinement landed in PR #1491.
+
+**Substrate refinements distilled from this consumer** (PR #1491):
+
+- `HandleRef::expect_owned_by(owner, type_tag) → Result<Uuid, String>` — canonical validation
+- `CommandRequest::handle_id_or_legacy(...)` — dual-shape resolver for any migration
+
+Both replaced ~35 lines of inline boilerplate per future migration with one method call each. The data cursor migration was the proving ground — refinements that came out of it benefit every future consumer.

+# Entity Chain of Custody — Scope: Slice 1
+
+**Status:** Slice 1 (per-citizen home + per-persona SQLite) **landed in PR #1519**. Slices 2–6 are **not yet committed work** — see [`docs/planning/ENTITY-CHAIN-OF-CUSTODY-ROADMAP.md`](../planning/ENTITY-CHAIN-OF-CUSTODY-ROADMAP.md) for the design intent + open questions each subsequent slice must answer.
+**Doctrine:** [[orm-everything-not-hand-edited-files]], [[personas-are-citizens-airc-is-identity-provider]], [[persona-identity-derives-from-source-id]], [[airc-headers-are-the-routing-layer]], [[continuum-thesis-airc-is-the-medium]].
+**Companion:** [ENTITY-DERIVE-ARCHITECTURE.md](ENTITY-DERIVE-ARCHITECTURE.md) (the schema layer this builds on).
+
+## Why this doc exists (and what it scopes to)
+
+Joel 2026-06-03 described a vision in which every substrate entity is signed by its writer, linked into a Merkle chain, portable across the grid via airc, and authored by a uniform "citizen" abstraction (persona / human / external AI). That vision is *correct direction* but multi-slice; this PR delivers **only the foundation slice**. Everything beyond that is intentionally moved to the planning doc so the substrate isn't enshrining commitments it hasn't designed.
+
+The architecture doc describes what IS built; the planning doc describes what's NEXT with open questions named.
+
+## What slice 1 settled
+
+Per-citizen home directory + per-persona SQLite scoping. Every citizen (today: personas; tomorrow: humans + external AIs) has a directory on disk:
+
+```
+<continuum_root>/personas/<agent_name>/
+    airc/              ← airc keypair (managed by airc-lib)
+    seed.json          ← PersonaIdentityProvider's seed
+    engrams.sqlite     ← OrmStore<Engram> + OrmStore<EngramRecallMetadata>
+```
+
+From this single rooted path the substrate finds:
+- The citizen's identity (airc Ed25519 keypair in `airc/`).
+- The citizen's entity stores (per-collection SQLite files in the home root).
+- Any future per-citizen state (signing-key derivation, Merkle chain head, per-collection metadata).
+
+`PersonaHome::for_persona(continuum_root, agent_name)` is the typed surface; `AdmissionState::for_persona(home, recall_metadata)` is the one-call entry point that opens the engram store, wires the production `OrmPersistenceSink`, rehydrates state from disk, and returns the configured AdmissionState.
+
+The per-citizen scoping is what makes everything beyond it possible — without separate homes, signing keys + chain heads + persona-specific entity stores have nowhere to live. **This is the only commitment in this PR.**
+
+## Citizen taxonomy
+
+The substrate distinguishes two roles when an entity gets written:
+
+- **Originating agent** — the semantic producer. "Claude said this." May or may not hold a local keypair.
+- **Attesting citizen** — the local citizen who received + admitted the entity into the substrate. Always holds a keypair. Signs the entity attesting "I received this from `originator`."
+
+For local citizens (personas Paige/Niko, human Joel running the substrate on his own machine) the originator and the attesting citizen are the same. For remote AIs accessed via API (Claude, openclaw, Hermes) they diverge — the attesting citizen is the local adapter that received the response; the originator is the API agent that produced it. The local adapter has a real keypair and signs the attestation; the originator name is recorded but not cryptographically attested.
+
+**This distinction is design intent for slice 2** (when entities gain `author_peer_id` + `content_hash`). It is not implemented today. The planning doc names it explicitly so slice 2's entity-schema work captures it.
+
+## Relationship to forge-alloy
+
+[FORGE-ALLOY-SPEC.md](FORGE-ALLOY-SPEC.md) defines a *proof pattern*: an artifact carries a content hash, signature(s), dependency references, methodology citations. The chain-of-custody work generalizes the **pattern** (artifact + verifiable lineage), not the specific contract — forge artifacts carry multi-party settlement signatures, dependency refs to base models, methodology citations, and falsifiable prior metric baselines; entities under slice 2+ would carry single-writer signed chains. They **rhyme** but are not the same proof contract.
+
+A future trait `ProofContract` (not yet written) might capture the shared shape — `content_hash() / signature() / previous()` — so verifying code generalizes across both. That's a slice-2+ design decision.

+# Entity Derive Architecture — The Rust-First, Generated-Everywhere ORM
+
+**Status:** Foundation landed (PRs `758fa1cf8`, `7d5034b9d`). Engram migrated. AdmissionState wire-up + RecallMetadata derive in progress (`#168`).
+**Doctrine:** [[orm-everything-not-hand-edited-files]], [[no-sql-everything-through-orm-entities]], [[organization-purity-as-we-migrate]] (E=mc² compression).
+
+## The thesis
+
+**Entities are defined exactly once, in a Rust struct. Everything else is generated.**
+
+Per Joel 2026-06-03: "Entities need to be defined, and in one place, rust (we are headless), then generated for all places, easy to do this elegantly like we did with decorators in ts, but for rust."
+
+The Rust struct is the single source of truth for what an entity IS. The ORM schema, the TS wire type, the JSON export/import shape, the persistence layer, and the future-grid-replicated copy all fall out of that one struct. **Drift between the struct and any consumer is a structural impossibility, not a discipline problem.**
+
+This supersedes the TS-decorators-as-canonical approach documented in [ORM-PHASE-2-DESIGN.md](ORM-PHASE-2-DESIGN.md) — the substrate is headless and Rust-native, so the canonical authoring path is Rust-first. TS bindings are generated downstream by ts-rs.
+
+## The three load-bearing layers

+
+Adding a field to the Rust struct propagates everywhere automatically. Removing a field surfaces failures at compile time + at the schema-migration check. **The canonical commit unit is "edit the struct"**, not "edit the struct AND edit the schema AND edit the TS binding AND edit the persistence shim."
+
+## The derive macro shape
+
+`#[derive(Entity)]` lives in the `continuum-orm-derive` crate. It reads the struct + attribute annotations and emits `impl OrmEntity for #name`. The Rust analogue of TS class decorators — additive, composes with other derives, no surprise auto-inclusion.
+
+### Struct-level attributes
+
+- `#[entity(collection = "name")]` — REQUIRED. The collection name (table name in SQL backends).
+- `#[entity(index(name = "...", fields = ["a", "b"], unique = true))]` — composite multi-field index. Repeat for multiple.
+
+### Field-level attributes
+
+- `#[entity(primary_key)]` — declares this field IS the BaseEntity id (a bare `Uuid`). Pulls in `base_entity_fields()` (id + createdAt + updatedAt + version) and skips emitting the field separately. Use when the entity carries its primary key as a top-level `Uuid` rather than embedding a `BaseEntity` struct.
+- `#[entity(indexed)]` — single-field B-tree index.
+- `#[entity(unique)]` — unique constraint.
+- `#[entity(nullable)]` — explicit nullable (auto-applied for `Option<T>`).
+- `#[entity(json)]` — force JSON column (override the inferred type). Useful for tagged-union enums and nested structs.
+- `#[entity(skip)]` — exclude from schema (in-memory only). Pair with `#[serde(skip)]` to also keep out of the wire payload.
+- `#[entity(foreign_key("collection.field", on_delete = "cascade", on_update = "restrict"))]` — declare a real FK reference. Cascade keywords: `"restrict" | "cascade" | "set_null" | "no_action"`. Defaults to `Restrict` on both.
+
+### BaseEntity composition (canonical: Pattern A, transitional: Pattern B)
+
+**Pattern A — CANONICAL — bare `Uuid id` with `#[entity(primary_key)]`:**
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, TS, Entity)]
+#[serde(rename_all = "camelCase")]
+#[entity(collection = "engrams")]
+pub struct Engram {
+    #[entity(primary_key)]
+    pub id: Uuid,
+    // ... domain fields
+}
+```
+
+The id IS the BaseEntity.id semantically. Adapter manages createdAt / updatedAt / version transparently in `DataRecord.metadata`. This is the **canonical default** for new entities — the entity struct stays small + focused on domain payload, the adapter handles base-entity bookkeeping. Engram migrated to this pattern.
+
+**Pattern B — transitional — embedded `BaseEntity` via `#[serde(flatten)]`:**
+
+```rust
+#[derive(Debug, Clone, Serialize, Deserialize, Entity)]
+#[serde(rename_all = "camelCase")]
+#[entity(collection = "chat_messages")]
+pub struct ChatMessage {
+    #[serde(flatten)]
+    pub base: BaseEntity,
+    pub author_id: Uuid,
+    pub content: String,
+}
+```
+
+The BaseEntity struct is embedded; the derive recognizes it by type name. Use **only** when the entity has external callers that read `entity.base.created_at` directly at the Rust level. Most entities don't need this — they read timestamps off `DataRecord.metadata` if they need them.
+
+**Per the compression principle**: Pattern A is the default. New entities should use it. Pattern B exists for legacy migrations + the narrow case above. A future audit ticket should walk existing Pattern B users and migrate any that don't have legitimate `entity.base.*` access patterns to Pattern A. The two are mutually exclusive per entity (the derive enforces this).
+
+## Type inference (Rust type → FieldType)
+
+| Rust type                       | FieldType  | Notes                                |
+|---------------------------------|------------|--------------------------------------|
+| `String` / `&str`               | `String`   |                                      |
+| `Uuid` (by type-name match)     | `Uuid`     |                                      |
+| `bool`                          | `Boolean`  |                                      |
+| `u*` / `i*` / `f32` / `f64`     | `Number`   | SQLite uses NUMERIC affinity         |
+| `Vec<_>` / `HashMap` / `BTreeMap` / `HashSet` | `Json` | JSON-serialized container |
+| `Option<T>`                     | inner T's type + `nullable = true` |  unwrapped one level |
+| Enum (variant-only)             | `Json`     | Tagged-union enums ride intact       |
+| Any other named struct          | `Json`     | Override with `#[entity(...)]`       |
+
+Override with `#[entity(json)]` to force any field to a JSON column.
+
+## Relational schema — FKs are first-class
+
+`SchemaField` carries:
+
+```rust
+pub struct SchemaField {
+    pub name: String,
+    pub field_type: FieldType,
+    pub indexed: bool,
+    pub unique: bool,
+    pub nullable: bool,
+    pub max_length: Option<usize>,
+    pub foreign_key: Option<ForeignKeyRef>,
+}
+
+pub struct ForeignKeyRef {
+    pub collection: String,
+    pub field: String,
+    pub on_delete: CascadeRule,
+    pub on_update: CascadeRule,
+}
+
+pub enum CascadeRule { Restrict, Cascade, SetNull, NoAction }
+```
+
+Both `SqliteAdapter` and `PostgresAdapter` emit `FOREIGN KEY (...) REFERENCES ...(...) ON DELETE ... ON UPDATE ...` in `CREATE TABLE`. SQLite gets `PRAGMA foreign_keys=ON` so the constraints are enforced (SQLite parses but ignores FK by default).
+
+**Real referential integrity at the DB layer.** Application code doesn't enforce "when this engram dies, its recall metadata dies too" — the DB does it. `[[no-fallbacks-ever]]` extended to relational invariants.
+
+## The typed persistence rail: `OrmStore<T>`
+
+`crate::orm::OrmStore<T: OrmEntity + Serialize + DeserializeOwned>` wraps an `Arc<dyn StorageAdapter>` and provides:
+
+```rust
+OrmStore::<T>::new(adapter).await?       // schema ensure, idempotent
+store.save(id, &entity).await?
+store.find_by_id(id).await? -> Option<T>
+store.find_all().await? -> Vec<(Uuid, T)>
+store.update(id, &entity).await?
+store.delete(id).await? -> bool
+```
+
+**Compression principle in action.** ONE generic helper, every `T: OrmEntity` gets save/find/update/delete for free. Add `impl OrmEntity for FooEntity` (or just `#[derive(Entity)]`), use `OrmStore<FooEntity>` — works immediately. No per-entity store + migration + serializer trio.
+
+## The portability payoff
+
+Because the entity contract is `OrmEntity + Serialize + DeserializeOwned`:
+
+- **JSON export/import** — every entity round-trips through `serde_json::to_value` / `from_value` for free.
+- **TS bindings** — ts-rs generates the TS type from the same struct.
+- **Schema-as-data** — `CollectionSchema` is itself `Serialize` + ts-rs-exported. Schemas can ship over the wire or land in a registry file.
+- **Backend-agnostic** — SQLite today, Postgres tomorrow, future grid-replicated tier. All read the same `CollectionSchema`.
+- **Format-agnostic** — swap `serde_json` for `serde_yaml` / `serde_cbor` / `postcard` to export entities in YAML / CBOR / binary with zero entity changes.
+
+This is the substrate plumbing that makes **persona portability across continuums** structural rather than aspirational. A persona's engrams export as JSON, ship across the grid, import into another continuum's adapter — same shape on the receiving end *when the two continuums run compatible entity schemas* (see "Schema evolution" below). The grid-as-distributed-gene-pool from [[persona-breeding-substrate-supports-it]] falls out without redesign once schema-evolution semantics are pinned.
+
+## Schema evolution
+
+The "swap serde_json for serde_yaml" portability claim above only holds when both ends speak the same entity schema. The substrate does NOT solve cross-version schema evolution today; this section names the scope and the open work so future slices don't accidentally break grid-flow portability.
+
+**What works today:**
+
+- **Additive field changes** — adding a new `Option<T>` field to an entity is forward-compatible. Older serialized data has no value for the new field; serde populates `None`; the entity loads cleanly.
+- **Adding enum variants** — only safe if every deserializer either knows the new variant or uses `#[serde(other)]` to catch it. The substrate does NOT currently apply `#[serde(other)]` consistently. **Adding an `EngramKind` variant today breaks deserialization on older substrate versions.**
+- **Field-level renames** — break serde round-trip in both directions unless `#[serde(rename = "...")]` or `#[serde(alias = "...")]` is used. Same caveat: not consistently applied.
+
+**Non-goals for v1:**
+
+- No automatic migration of stored data across breaking changes. If an entity's schema breaks (renamed field, removed field, changed type), the substrate provides no auto-migration path. The OrmStore's `ensure_schema` would happily create the new schema next to the old; existing rows would error on deserialization.
+- No cross-version signature compatibility. When entity chain-of-custody slice 3 lands, the signed content_hash will cover the canonical serde form. Field renames or reorderings would invalidate signatures. The chain head invalidates — by design.
+
+**What needs designing before grid-flow lands** ([entity-chain-of-custody-roadmap](../planning/ENTITY-CHAIN-OF-CUSTODY-ROADMAP.md) slice 5+):
+
+- Schema version field on every entity (`schema_version: u32`?) so receivers can detect mismatch.
+- Per-entity migration registry with idempotent "v1 → v2 → v3" transforms.
+- Catch-all variants on every enum (`#[serde(other)] Unknown(serde_json::Value)`).
+- Explicit "canonical form" definition for content_hash computation so adding optional fields doesn't break signatures.
+
+**Until those are designed, the portability claim is "exports work between continuums on the same SHA"** — a real win for substrate-internal use, not yet a cross-continuum mesh.
+
+## Concrete adapters: what's migrated
+
+- **`Engram`** — fully derive-driven (`#[derive(Entity)]` + per-field attrs). Round-trips through real SQLite via `OrmStore<Engram>`. Hand-written `impl OrmEntity` block deleted. Tests pass. PR `7d5034b9d`.
+
+## Migration in progress
+
+- **`RecallMetadata`** — needs `Serialize + Deserialize` derives added (currently a `Copy` hot-path struct in `DashMap`). Then `#[derive(Entity)]` with `#[entity(foreign_key("engrams.id", on_delete = "cascade"))]` on `engram_id`. **Real FK to engrams.** Cascading delete handled by the DB.
+- **`AdmissionState`** — gains `Option<Arc<OrmStore<Engram>>>` + `Option<Arc<OrmStore<RecallMetadataRow>>>`. `admit()` writes through. `record_recall_hit` + `apply_decay` update. `load_at_boot()` rehydrates `Vec<Engram>` + `DashMap<Uuid, RecallMetadata>` from disk. **Engrams survive process restart for the first time in the substrate's history.**
+- **`RoleTemplate`**, **`HwTierDescriptor`** — already declared their `OrmEntity` impls by hand (#123). Migration to `#[derive(Entity)]` is a sed-style mechanical change that deletes hundreds of lines.
+- **Future entities** — every new entity authors as `#[derive(Entity)]` from day one. Per [[organization-purity-as-we-migrate]] no new hand-written `impl OrmEntity` blocks land in module code.
+
+## Adapter dedup (a latent bug found and fixed)
+
+Both `SqliteAdapter` and `PostgresAdapter` hardcoded the BaseEntity columns (`id / created_at / updated_at / version`) at the top of `CREATE TABLE`, then ALSO iterated `schema.fields`. When schemas declared BaseEntity columns via `base_entity_fields()` (the documented contract), CREATE TABLE crashed on duplicate column name.
+
+Fix: `crate::orm::entity::is_base_entity_column()` helper. Both adapters skip schema.fields whose snake_case name matches. Single source of truth lives at the adapter level; schemas declare intent without forcing entities to know each backend's CREATE TABLE layout.
+
+## SQLite numeric affinity (a second latent bug found and fixed)
+
+SQLite stored `FieldType::Number` as REAL affinity, coercing integers to floats. The bug was latent because no OrmEntity had ever round-tripped a typed `i32`/`i64` until the derive's test entity used `delta: i32`. Changed to NUMERIC affinity — preserves integers as integers, floats as floats.
+
+## Cross-cutting doctrines
+
+- [[no-sql-everything-through-orm-entities]] — module code never touches raw SQL. The ORM owns the backend.
+- [[no-fallbacks-ever]] — FK constraints enforce referential integrity at the DB, not at the application layer. Typed errors on every adapter call.
+- [[observability-is-half-the-architecture]] — every entity is inspectable + exportable; the persistence layer is debuggable end-to-end.
+- [[host-the-seemingly-impossible]] — the substrate hosts what would be expensive infrastructure on consumer hardware (SQLite locally, Postgres optionally, grid-replicated in the future).
+
+## Files
+

+# Every Model Included — L1 Budget Design As The Substrate's Cornerstone
+
+> Why getting the L1 RAG budget right is the substrate's single most
+> load-bearing decision for "no base model excluded from anywhere in
+> continuum."
+
+**Status:** Design (2026-05-31 synthesis); implementation in flight
+on `feat/persona-helper-ai-as-airc-citizen` slice 9.
+
+**Parent:** [`COGNITION-CACHE-HIERARCHY.md`](COGNITION-CACHE-HIERARCHY.md) (the multi-tier cache framework) · [`COGNITION-ALGORITHMS.md`](COGNITION-ALGORITHMS.md) (the algorithms running over it) · [Continual Learning section of the project README](../../README.md#one-solution-to-continual-learning)
+
+---
+
+## The thesis stated plainly
+
+Joel, 2026-05-31:
+
+> "Every context yes has its own window because models have dramatic
+> differences, which is why this is so mission critical. We can't
+> exclude any base model from anywhere in continuum. For this reason
+> basic text models has vision, hearing, speech, and avatars. The
+> system made those accommodations possible."
+
+The substrate's whole bet — "infrastructure compensates for model
+capability beats smarter models with no infrastructure" (README L158) —
+runs through the L1 budget layer. If L1 can scale gracefully across
+the 250× range of base-model context windows (4k local Qwen → 200k
+Claude API → 1M+ future) AND compose with the sensory bridges that
+give every persona vision/hearing/speech/avatar regardless of base
+model, then **every base model is includable everywhere in continuum**.
+If L1 can't, the substrate quietly fractures into "this feature only
+works with frontier models" — the cloud-AI lock-in pattern the
+substrate explicitly refuses.
+
+The bet stands or falls at this layer. That's why getting it right
+matters disproportionately.
+
+---
+
+## What "no base model excluded from anywhere" requires
+
+Four architectural mechanisms, all in the L1 budget design (see
+`persona/rag_budget.rs` for the shipped implementation):
+
+### 1. Continuous scaling across the full context-window range
+
+The allocator math must work at 4k tokens AND at 1M+ tokens with the
+**same code path** — no `if context_window > 32768` branches inside
+the algorithm. Different scales, same shape.
+
+How the flexbox allocator does it:
+- Reserved tokens (system + completion) are subtracted off the top in
+  absolute terms
+- `floor_tokens` / `min_tokens` / `max_tokens` per source are
+  absolute, set by the per-model preset (the recent-universal floor
+  N=5 on a 4k model, N=50+ on a 200k model — auto-scales via the
+  preset, not via branching in the algorithm)
+- Distribution by priority weight is proportional, scale-free
+- Per-source max caps prevent any one source from devouring the
+  context regardless of window size
+
+The same `FlexboxRagBudgetAdapter` handles every model. A future
+`LearnedRagBudgetAdapter` will tune per-persona regret signals from
+the same telemetry; that's also scale-free.
+
+### 2. Source-side compression instead of allocator-side clipping
+
+When budget is tight, **sources self-compress** by emitting their
+content at a lower `ResolutionPreference` (Raw → Compressed →
+Summarized → Placeholder). The allocator never clips mid-content.
+
+This is what lets a 4k local Qwen actually have the same conversation
+shape as a 200k Claude:
+- Conversation source delivers `Raw` last 5 messages instead of `Raw`
+  last 50, but they're complete messages
+- Engram source delivers `Compressed` engram summaries instead of `Raw`
+  episodic engrams
+- Vision source delivers `Compressed` "user is wearing a blue shirt
+  with a guitar" instead of `Raw` 1024×1024 base64 image
+- Audio source delivers `Summarized` "user said something about debugging"
+  instead of `Raw` waveform
+
+Same persona, same engrams, same long-term knowledge. The IN-THE-MOMENT
+working set shrinks gracefully when the model can't hold more. The
+substrate doesn't lie about what got compressed — `RagDelivery.
+resolution_used` surfaces it for telemetry.
+
+### 3. Honest tradeoffs when even compression can't satisfy required floors
+
+The no-clipping doctrine has a corollary: when even the lowest
+resolution can't fit a `required = true` source's `floor_tokens`, the
+substrate **escalates** rather than silently truncating. The
+`AllocationState::UnderProvisioned` value + `BudgetAllocation.
+escalation_needed` flag surface this:
+
+- A 1.7B Qwen with 2k context trying to hold a 6-hour code-review
+  conversation: floors don't fit → escalation. The substrate's
+  response is the operator's choice (downshift to local 4B with 32k,
+  prompt the host to switch persona, switch the conversation to
+  multi-turn summarization mode). Not the substrate's choice to make
+  invisibly.
+
+This is the third mechanism: the substrate is HONEST about its
+limits. Every other AI-platform substrate I've seen quietly clips
+when the model can't fit; ours explicitly refuses, surfaces the
+state, lets the operator decide. Trust earned through honesty.
+
+### 4. Capability bits flowing through `SubstrateContext`
+
+The per-call `SubstrateContext` (persona_id + now_ms + airc_room +
+turn_id today; `has_vision_native` / `has_audio_native` / `tokenizer_handle`
+tomorrow) flows through every source's `deliver()` call. Sources read
+the context to decide what resolution to ship at:
+
+```rust
+// Future EngramSource pseudo-code
+async fn deliver(&self, ctx: &RagContext, budget: u32, pref: ResolutionPreference) -> RagDelivery {
+    let resolution = if ctx.has_vision_native && pref == ResolutionPreference::Raw {
+        // model can take raw images; engrams with image content stay raw
+        ResolutionPreference::Raw
+    } else {
+        // text-only model or budget-constrained — describe instead
+        ResolutionPreference::Compressed
+    };
+    // ... deliver engrams at the chosen resolution, complete units only
+}
+```
+
+Same source code. Same prompt assembly. Different deliveries depending
+on what the running model can natively understand. The substrate
+**compensates inside the budget layer** for what the model lacks.
+
+---
+
+## How this composes with sensory bridges + prompt assembly
+
+The substrate's "every base model gets every sense" claim
+(CLAUDE.md sensory architecture; README L301-313) decomposes into:
+
+```
+                                +-------------------+

+```
+
+The `RagSource` trait + `RagContext`-aware delivery means **each
+sensory bridge plugs in as a source**, with the budget allocator
+treating it like any other RAG source. Vision-incapable model? The
+`VisionSource` calls `VisionDescriptionService` and emits text-
+described frames. Audio-incapable model? The `AudioSource` calls STT
+and emits transcribed text. Speech-incapable model? The `OutputSource`
+(slice 13+) sends text to TTS for audio synthesis.
+
+All of this routes through the same allocator using the same trait
+contract. **A 3B local model gets vision, hearing, speech because the
+substrate's sources COMPENSATE inside the budget allocation.** Not
+because the model can do it natively, but because the substrate
+provides the compensation rails the sources ride on.
+
+---
+
+## The bet, stated as an operational test
+
+A reasonable user installs continuum on a MacBook Air M1 with no
+cloud API keys. The substrate spins up Pax on local Qwen 4B (32k
+context). Pax can:
+
+- See the user's t-shirt and comment ("Cool guitar shirt — Strat?")
+  — vision via `VisionSource` calling `VisionDescriptionService`,
+  delivered at `Compressed` resolution inside the budget
+- Hear the user say "let me share my screen" — audio via `AudioSource`
+  calling STT, delivered at `Summarized` resolution
+- Recall the morning's code-review conversation from yesterday — via
+  `EngramSource` reading L2/L3 engrams at `Compressed` resolution
+  to fit the 32k budget
+- Respond by voice — output text rendered through TTS
+
+Same Pax, same engrams, same genome. The 32k budget is tighter than
+a 200k cloud Pax's working set, so the compressed-resolution
+deliveries are more aggressive. But every capability is **present**.
+Nothing is excluded "because the model is too small." That's the
+test the substrate must pass before "every base model includable
+everywhere" stops being aspiration and becomes operational reality.
+
+---
+
+## What's shipped (slice 9 commits)
+
+In `feat/persona-helper-ai-as-airc-citizen` `94e81637f`:
+
+- `FlexboxRagBudgetAdapter` — continuous-scale allocator, no
+  branching by window size
+- `RagSource` trait — source-owned atomic units, supports
+  `ResolutionPreference` + persona-scoped continuation cursors
+- `SubstrateContext` + `RagContext` — Android-style first-parameter
+  pattern; persona_id + now_ms + airc_room + turn_id today, capability
+  bits to follow when EngramSource needs them
+- `AllocationState` — telemetry-honest per-source outcome
+  (Satisfied / FloorOnly / Dropped / UnderProvisioned)
+- `escalation_needed` flag — substrate refuses to silently
+  exclude a required source
+
+## What's next (slices 10+)
+
+- **Slice 10**: real `EngramSource` reading from RecallMetadata +
+  admission_state, ranking by salience × structural × recency
+- **Slice 11**: real `ConversationSource` reading inbox + recent
+  message cache
+- **Slice 12**: PromptAssembly composes allocator + sources into the
+  final prompt string sent to the model adapter
+- **Slice 13**: `VisionSource` + `AudioSource` plugging the sensory
+  bridges into the RAG source ecosystem
+- **Slice 14**: capability bits on `SubstrateContext`
+  (`has_vision_native`, `has_audio_native`, `tokenizer_handle`) +
+  source adaptation based on them
+
+By slice 13–14, the operational test above becomes runnable: a
+local Qwen-backed Pax with full sensory + cognitive parity to a
+cloud Pax, differing only in working-memory window size.
+
+---
+
+## Why this doc exists
+
+The L1 budget layer LOOKS like an implementation detail — a small
+flexbox allocator, a trait, some presets. But the substrate's whole
+inclusivity thesis runs through it. Every other architectural choice
+the substrate makes (citizen-shaped personas, identity persistence,
+continual learning, evolution, communities) is downstream of "every
+base model is includable." That's downstream of getting this layer
+right.
+
+So when reviewers look at `persona/rag_budget.rs` and think "this is
+a CSS-flexbox token allocator with some presets" — yes, that's the
+implementation. The architectural significance is at the substrate
+thesis level: this is the layer where the substrate either
+**accommodates every base model** or quietly **excludes the ones that
+don't have enough context room**. Tonight's slice 9 is where we
+took the side of accommodation.

+# ForgeRecipe — Author the recipe once, the foundry generates the artifact
+
+**Issue**: continuum#1164 (this design)
+**Status**: Reviewed — open questions resolved (see §7); ready for Phase 1
+**Pairs with**: [FORGE-ALLOY-SPEC.md](./FORGE-ALLOY-SPEC.md), [FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md](./FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md), [grid/FORGE-ALLOY-PROOF-CONTRACTS.md](../grid/FORGE-ALLOY-PROOF-CONTRACTS.md)

+
+> **Continuum-wide pattern (per claude-tab-2 review).** The
+> `ForgeRecipe` (authored input) → `ForgeArtifact` (generated output)
+> split is the **same** architectural shape the engram thread (#1121)

+> Continuum is converging on: pipelines have an authored-input entity
+> + a generated-output entity, conflating them is the anti-pattern.
+> Every future pipeline subsystem should follow this shape.
+
+> **TL;DR.** Today every successful forge requires hand-authoring an
+> `.alloy.json` with the same set of fields (name, prose, methodology
+> blockquotes, stage notes, benchmark configs, baselines, hardware tier,
+> etc.). That's anti-architectural — the inputs aren't data, they're
+> ad-hoc files. This doc proposes a `ForgeRecipe` Continuum entity that
+> captures the inputs once, and a `Foundry` pipeline that takes the

+> output. The forge **never consumes a hand-authored alloy**; the foundry
+> generates it. The pattern matches how every other Continuum subsystem
+> works: data lives in entities, behavior lives in pipelines.
+
+> **Recipe graph rule.** A recipe is a reusable template. It defines the
+> content/activity shape, execution stages, capabilities, and defaults.
+> It is not the live room/activity itself. Running or instantiating a

+
+## 1. Problem
+
+The qwen3-coder-30b-a3b-compacted-19b-256k v1 publish (alloy hash
+`aa61c4bdf463847c`) required ~6 manual edits during the publish loop —
+paper-speak hallucination cleanup, naming-convention fixes, tag
+overflow trimming, headline subtitle bugs, benchmark renderer
+fallthroughs. Every one of those was a manual touch on prose that lived
+in a hand-authored `.alloy.json`. None of them were code bugs; they
+were content-authoring bugs.
+
+**The architectural failure:** the alloy file mixes *recipe inputs*
+(name, description, methodology, stages, benchmark targets, hardware
+tier, prose) with *execution outputs* (results.benchmarks, alloy hash,
+forgedParamsB, hardwareVerified, verify URL, published HF repo URL).
+A human authors the inputs, the foundry runs the stages and fills in
+the outputs, then the publish step reads the merged file. The merge
+happens *in the human's text editor*, which is exactly where you do
+NOT want a forge pipeline to converge.
+
+**The architectural fix:** split the entity. Inputs become a
+`ForgeRecipe` entity in the Continuum data layer (authored once,
+edited via standard `Commands.execute('data/...')` primitives). The
+foundry consumes the recipe + execution results, emits a `ForgeAlloy`
+artifact entity (= the existing `ForgeAlloy` shape from
+[FORGE-ALLOY-SPEC.md](./FORGE-ALLOY-SPEC.md), now treated as foundry
+*output*, never input). The publish step reads the artifact entity,
+not a file.
+
+Same shape as how the engram thread (continuum#1121) keeps the
+`Engram` entity (output) separate from the `AdmissionCandidate`
+(input) — separate types so each side's invariants are obvious.
+
+---
+
+## 2. ForgeRecipe entity (proposed)
+
+The `ForgeRecipe` is the **authored input** — everything a human
+decides about a forge run before any execution happens.
+
+```typescript
+/**
+ * ForgeRecipe — Author the recipe once. Foundry generates the alloy.
+ *
+ * Stored in Continuum ORM. Edited via standard data/* commands.
+ * NEVER consumed directly by `publish_model.py` — that script reads
+ * the ForgeArtifact (= ForgeAlloy with results) the foundry emits.

+
+### What's NOT on `ForgeRecipe` (deliberately)
+
+- `results.*` — populated only on `ForgeArtifact` (= populated alloy)
+- `alloy_hash`, `forged_model_ids`, `hardware_verified[]` — outputs
+- `receipt.*`, `verify_url`, `published HF repo URL` — outputs
+- `integrity.*` (CodeAttestation, signatures) — outputs of execution
+- Anything that requires running a stage to know the value
+
+The clean split: if you can know it BEFORE running the foundry, it
+belongs on the recipe. If you can only know it AFTER, it belongs on
+the artifact.
+
+---
+
+## 3. ForgeArtifact (= today's ForgeAlloy, repositioned)
+
+The existing `ForgeAlloy` entity from
+[FORGE-ALLOY-SPEC.md](./FORGE-ALLOY-SPEC.md) becomes the **output
+artifact** of the foundry — never authored by hand. To make the
+intent unambiguous, this doc proposes renaming the entity to
+`ForgeArtifact` (or aliasing `ForgeAlloy → ForgeArtifact` if backwards
+compatibility matters more than naming clarity).
+
+```typescript
+interface ForgeArtifact extends BaseEntity {
+  // ── Inherits all recipe fields ─────────────────────────────────
+  ...ForgeRecipe;                     // Recipe shape, frozen at run time
+
+  // ── Recipe lineage ─────────────────────────────────────────────
+  recipeId: UUID;                     // Which recipe was run
+  recipeVersion: string;              // Recipe version at run time
+  forgedAt: string;                   // ISO timestamp foundry started
+
+  // ── Execution results (what only the foundry knows) ────────────
+  results: AlloyResults;              // benchmarks, perplexity, samples, etc.
+  forgedParamsB: number;              // After prune/compact
+  activeParamsB: number;              // For MoE: active params per token
+  hardwareVerified: HardwareProfile[];  // Devices the artifact ran on
+  alloyHash: string;                  // Content-hash of the populated alloy
+  receipt?: AlloyReceipt;             // Publication URLs, verify URL
+  integrity?: IntegrityAttestation;   // Signatures, code attestation
+}
+```
+
+The publish path reads `ForgeArtifact`. It does NOT read a file.
+
+---
+
+## 4. Foundry pipeline contract
+
+The Foundry is the executor. It owns the recipe→artifact transformation.
+
+```typescript
+// Stateless, deterministic given (recipe + base model snapshot + hardware).
+async function runFoundry(args: {
+  recipe: ForgeRecipe;
+  hardwareNode: HardwareNodeRef;       // Where to run
+  publishTarget?: PublishTarget;       // HF org/repo if publishing
+}): Promise<ForgeArtifact> {
+  // 1. Materialize base model from source.baseModel
+  // 2. For each stage in recipe.stages:
+  //    - Execute the stage (prune, train, lora, quant, eval, etc.)
+  //    - Collect stage-level metrics + notes for the trace
+  // 3. Run all evaluationBenchmarks; collect results
+  // 4. Verify against priorMetricBaselines (falsifiability gate)
+  // 5. For each quantTier, produce the GGUF/etc. variant
+  // 6. Compute alloyHash from the populated artifact JSON
+  // 7. (Optional) Publish to HF + record receipt
+  // 8. Persist as ForgeArtifact entity in Continuum data layer
+  // 9. Return the artifact
+}
+```
+
+### Continuum integration
+
+Recipe authoring + foundry execution use the standard primitives:
+
+```typescript
+// Author a recipe (or import one from another node)
+await Commands.execute('data/upsert', {
+  collection: 'forge_recipes',
+  entity: recipe as ForgeRecipe,
+});
+
+// Run the foundry on a recipe
+const artifact = await Commands.execute('forge/run', {
+  recipeId: recipe.id,
+  hardwareNode: 'm5-pro@local',
+  publishTarget: { org: 'CambrianTech', repoTemplate: '{base}-{domain}-forged' },
+});
+
+// Query artifacts
+const recent = await Commands.execute('data/list', {
+  collection: 'forge_artifacts',
+  orderBy: [{ field: 'forgedAt', direction: 'desc' }],
+  limit: 10,
+});
+```
+
+`forge/run` is the new IPC handler that wraps `runFoundry`. It joins
+the cognition + grid IPC surface that already exists; nothing about
+this requires re-architecting how Continuum talks to Rust.
+
+### Native-truth + thin-SDK
+
+Same pattern as the rest of the system:
+- The foundry executor is **Rust-side** (heavy compute, model
+  manipulation, GGUF serialization). Lives in `continuum-core` or a
+  new `continuum-foundry` crate.
+- The recipe + artifact entities are defined in **Rust** with `#[derive(TS)]`
+  for the TS bindings (matches how `Engram` types ship per #1121).
+- The TS layer is a **thin SDK** that calls `Commands.execute('forge/...')`.
+  No business logic.
+
+---
+
+## 5. Migration plan
+
+### Phase 0: This doc (no code)
+- Land `FORGE-RECIPE-AS-ENTITY.md` for review
+- Get feedback on naming (ForgeArtifact vs keeping ForgeAlloy)
+- Get feedback on the split between recipe vs artifact field sets
+
+### Phase 1: ForgeRecipe entity + storage
+- Define `ForgeRecipe` Rust type with `#[derive(TS)]`
+- Add `forge_recipes` collection to the entity registry
+- Standard `data/*` commands work via the entity registry
+- Tests: serde roundtrip, ts-rs binding generation, schema validation
+
+### Phase 2: Foundry executor stub
+- New IPC: `forge/run` (takes recipeId, returns ForgeArtifact)
+- v1 stub: just runs the existing pipeline using the recipe as
+  input, persists the artifact. No new stages, no new behaviour —
+  just the same forge logic with the recipe as the single source
+  of truth for inputs.
+- Tests: mock executor returns synthetic artifact; round-trip
+  through `data/list`.
+
+### Phase 3: Migrate qwen3-coder
+- Author the qwen3-coder recipe in the new shape (one-time human
+  task; ~30 min)
+- Run foundry against it on the same hardware as the v1 publish
+- Diff the resulting artifact JSON against the hand-authored alloy
+- Resolve any drift (probably some prose fields the recipe didn't
+  capture; iterate)
+- Re-publish v1.1 from the foundry-generated artifact
+
+### Phase 4: Deprecate hand-authoring
+- `publish_model.py` rejects any `.alloy.json` that doesn't have a
+  `recipeId` populated (i.e., wasn't generated by the foundry)
+- Add a docs page: "How to author a forge recipe" (replaces "How to
+  edit an alloy file by hand")
+
+### Phase 5: Recipe library
+- Standard recipes shipped in the entity registry as seed data:
+  `qwen3.5-4b-code-aggressive`, `mistral-7b-multimodal-vision`, etc.
+- Anyone can clone + tweak via `data/upsert`
+- Recipe lineage (`parentRecipeId`) lets the foundry track derivations
+
+---
+
+## 6. What this enables
+
+- **Recipes are git-backed entities.** Edit history via the data layer's
+  audit log, not via per-file diffs.
+- **Recipes are forkable.** Two artifacts from the same base recipe
+  with different `quantTiers` is just two `ForgeArtifact` entities
+  pointing at one `ForgeRecipe`.
+- **Recipes are AIRC-shareable.** A peer publishes a recipe; you pull
+  it via `airc grid pull-recipe`; you run your own foundry on your
+  own hardware. The recipe is data; data already moves on AIRC.
+- **The forge becomes proof-able.** Per
+  [FORGE-ALLOY-PROOF-CONTRACTS.md](../grid/FORGE-ALLOY-PROOF-CONTRACTS.md),
+  the recipe is the *contract* the persona-self-seal v1 attests to;
+  the artifact is the *settlement* that proves the contract was
+  fulfilled. The split makes both signable independently.
+
+---
+
+## 7. Open questions — RESOLVED
+
+All 6 resolved per claude-tab-2's substantive review on PR #1165.
+Consensus positions captured here so Phase 1 implementation can
+proceed without re-litigating.
+
+1. **Naming → rename to `ForgeArtifact`.** The "alloy" metaphor was
+   about the multi-component nature of the OUTPUT (base + pruning +
+   quantization + LoRA → one composite). For the INPUT, `ForgeRecipe`
+   is unambiguous. For the OUTPUT, "Alloy" doesn't carry the
+   executed/measured/proven semantics that "Artifact" does. Renaming
+   friction is small + one-time; conceptual clarity is forever.
+   Existing `ForgeAlloy` entity → `ForgeArtifact` rename is part of
+   Phase 1.
+
+2. **Stage `notes` field → per-variant `notes?: string` on each stage
+   type.** Sidecar `Record<string, string>` keyed by stage index
+   would be order-fragile (insert a stage in the middle → all
+   index-keyed notes shift to wrong stages), findable only by
+   jumping back-and-forth, and hard to refactor (rename a stage
+   variant → sidecar key has to track). Per-variant is the discoverable,
+   stable, refactor-safe shape. Touches every stage type; one-time cost.
+
+3. **Quant tiers → top-level recipe field, NOT inside `QuantStage`.**
+   `QuantStage` is a single stage's execution config. Quant TIERS are
+   a property of the published artifact (one recipe ships multiple
+   variants like `["Q4_K_M", "Q5_K_M", "Q8_0"]`). Conflating them
+   inside `QuantStage` means changing "which tiers we ship" requires
+   editing the pipeline; top-level means clean axis of variation
+   independent of the stage that produces the variants.
+
+4. **Calibration corpus → `CorpusRef` on the recipe (pointer); bytes
+   live elsewhere.** The actual corpus (MB-GB) doesn't belong inside
+   Continuum's ORM. The proposed `CorpusRef` shape (name + hash +
+   sourceUrl) is correct. Where bytes live: HF datasets for shareable
+   corpora; foundry-node-local for proprietary. AIRC grid storage is
+   overkill for static corpora (AIRC is a coordination wire, not a
+   CDN). A separate `Corpus` entity ships later if/when corpus
+   discovery becomes a UX concern; v1 = pointer only.
+
+5. **`priorMetricBaselines` → pin per-recipe.** Reproducibility >
+   maintenance. A 2024 baseline + a 2026 baseline are DIFFERENT
+   scientific claims; resolving them via a centralized library hides
+   which claim was being made when the artifact published. Updating
+   the baseline = recipe revision (semver bump). The recipe IS the
+   document of record for what you measured against.
+
+6. **Migration timeline → audit-then-decide on Phase 4.** qwen3-coder
+   v1 publish is the only known in-flight forge per CLAUDE.md context.
+   If the audit confirms that, Phase 3 (qwen3-coder v1.1 = first
+   foundry-generated artifact) IS the migration. Phase 4 (`publish_model.py`
+   rejects hand-authored) gates on Phase 3.5 (count in-flight forges,
+   list owners, get acks before flipping the switch).
+
+### Additional resolved positions
+
+7. **Foundry stage executors MUST be Rust.** Existing
+   `forge-alloy/python/forge_alloy/types.py` is Python — Phase 2's
+   foundry executor goes in `core/continuum-core/src/foundry/`
+   (or new `continuum-foundry` crate) as Rust per the native-truth
+   rule. Python types stay as a generated-from-Rust client (or
+   hand-maintained thin SDK), NEVER as the authoritative type
+   definition. Otherwise we end up with a Python truth-layer that
+   drifts from the Rust types — same anti-pattern §4 warns about
+   for TS. Pinned explicitly here so Phase 2 can't accidentally
+   forge it the wrong direction.
+
+8. **`hashSha256` field name → align with admission's
+   `"sha256:<hex>"` format.** Admission (#1121 PR-3) uses
+   `content_hash: "sha256:<hex>"`. Forge's `CorpusRef.hashSha256`
+   should match the same canonical format for cross-domain
+   consistency. Phase 1 will rename to `contentHash: string` with
+   the `"sha256:<hex>"` shape.
+
+9. **`parentArtifactIds: UUID[]` future-proofing comment.** v1 has
+   `parentRecipeId?: UUID` (recipe lineage). Whether a recipe also
+   carries `parentArtifactIds` (artifacts whose insights informed the
+   new recipe) is intentionally one-directional in v1. Note in the
+   schema that this could expand later when bidirectional lineage
+   becomes load-bearing.
+
+10. **`licenseStrategy: "inherit_from_source" | "override"` —
+    deferred.** Defaulting to `apache-2.0` matches Continuum's stated
+    AGPL+permissive posture, but artifacts publishing TO HuggingFace
+    need to honor the BASE model's license (qwen3.5 has a custom
+    Tongyi Qianwen license). v1 = explicit `license` field on the
+    recipe (caller responsibility to set correctly). v2 (when we hit
+    the first license-mismatch incident) = add `licenseStrategy`
+    enum that auto-inherits when set to `inherit_from_source`.
+
+---
+
+## 8. Why this is the next sprint
+
+Per CLAUDE.md §FORGE TEMPLATE ARCHITECTURE: every successful forge
+requires the same set of fields. Treating those fields as data instead
+of files is the move that makes the second killer (and every killer
+after) ship without the ~6 manual touches the qwen3-coder publish
+required. This unblocks:
+
+- Faster publish loops (recipe edit → foundry rerun → new artifact)
+- Recipe-library shipping as standard Continuum seed data
+- AIRC-grid recipe sharing between peers (the recipe IS data, and
+  data moves on AIRC already)
+- Forge-alloy proof contracts ([grid/FORGE-ALLOY-PROOF-CONTRACTS.md])
+  having a clean separation between the *contract* (recipe) and the
+  *settlement* (artifact)
+
+---
+
+## 9. Out of scope (for this design doc)
+
+- Implementation. This is a design doc; phases 1-5 each ship as
+  separate PRs.
+- Recipe-library catalog UX (the "browse standard recipes" surface).
+- Re-rendering existing model cards from the new artifact shape
+  (separate UX pass).
+- Cross-grid recipe federation (peer A publishes a recipe; peers B
+  + C run it on their own hardware; results federate). That's a
+  follow-up that depends on the AIRC grid substrate maturing.

+# `generator` module — Design
+
+> **Status**: v1 shipped in PR #1487 (recursive bootstrap); v2 enriched scaffold in PR #1494 (matches Module Design Template).
+>
+> **File**: `core/continuum-core/src/modules/generator/` (mod.rs + types.rs + templates.rs)
+>
+> **Canonical reference**: [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)
+
+## Role
+
+**Commands** primitive, serving **architects + AI personas scaffolding new functionality**. Per Joel 2026-05-30:
+
+> *"We developed a generator so we could manufacture these patterns for new commands modules etc, which itself was a command. Meta."*
+
+The generator IS a module; the things it creates are modules; every operation it performs is a command. The system describes itself in its own terms — the recursive bootstrap.
+
+After PR #1494 (v2), authoring a new ServiceModule means running ONE command:
+
+```bash
+./jtag generate/module --name "chat_analyze" --commands "..." --stateful
+```
+
+…then filling in handler bodies. All envelope wiring, typed Params/Result skeletons, concurrency test scaffold, DESIGN.md skeleton, per-resource lock pattern, and ts-rs annotations are emitted automatically.
+
+## Command surface
+
+| Command | Params type | Result type | Status |
+|---|---|---|---|
+| `generate/module` | `GenerateModuleParams` | `GenerateModuleResult` | ✅ Rust (PR #1487 + #1494) |
+| `generate/command` (planned) | — | — | ❌ Not yet — add a new command to an existing module |
+| `generate/refresh` (planned) | — | — | ❌ Not yet — re-scan modules tree + refresh manifests/barrels |
+
+### `generate/module` spec
+
+Params:
+- `name: String` — lowercase ASCII identifier (validated; becomes Rust struct name + directory name)
+- `description: String` — embedded in mod.rs docstring + README + DESIGN.md
+- `commands: Vec<String>` — each becomes a dispatch arm + typed handler method + Params/Result type
+- `events_subscribed: Vec<String>` — wired into `ModuleConfig::event_subscriptions`
+- `events_published: Vec<String>` — documented in mod.rs docstring + DESIGN.md (no runtime wiring)
+- `priority: PrioritySpec` — one of `Realtime` / `High` / `Normal` / `Background`
+- `force: bool` — overwrite existing directory
+- `stateful: bool` — opt in to per-resource lock scaffold (DashMap + tokio Mutex + helper + concurrency test)
+
+Output (4 files per generation):
+- `mod.rs` — ServiceModule impl with typed envelope dispatch + handler methods + concurrency test
+- `types.rs` — `<Cmd>Params` / `<Cmd>Result` pair per declared command with `#[derive(TS)]`
+- `DESIGN.md` — per-module design skeleton with required 8 sections
+- `README.md` — author-facing summary + wire-up reminder
+
+## Cross-module dependencies
+
+**None.** Pure filesystem operations + template rendering. The generator is self-contained — it doesn't call any other module.
+
+## State model
+
+**Per-name locks** for the generation operation:
+
+```rust
+pub struct GeneratorModule {
+    workspace_root: Option<PathBuf>,
+    name_locks: DashMap<String, Arc<std::sync::Mutex<()>>>,
+}
+```
+
+`std::sync::Mutex` (not `tokio::sync`) because the protected critical section is purely synchronous filesystem I/O — no `.await` inside the lock. Blocking the tokio worker for the brief mkdir + 4 file writes is correct and avoids cascading the API into async.
+
+Lock entries are never evicted — module names are bounded (no unbounded production stream of unique names) and each entry is ~50 bytes. If memory ever matters, a TTL scan can be added without changing the protocol.
+
+## Events emitted
+
+**None.** Filesystem operations are the side effect.
+
+## Concurrency contract
+
+**Per-name lock** serializes concurrent same-name `generate/module` calls; different names stay fully parallel via DashMap's per-shard locking.
+
+### Pinned invariants (multi-thread tests)
+
+1. **`same_name_concurrent_generation_without_force_yields_one_winner`** — 8 racers, same name, no force; exactly ONE wins, 7 fail loud with "already exists" + escape hatch hint
+2. **`same_name_concurrent_generation_with_force_produces_consistent_final_state`** — 8 racers, same name, force=true; both files (mod.rs + README.md) carry the SAME `MARKER-XX` proving they came from ONE generation round (no torn state)
+3. **`different_names_concurrent_generation_runs_fully_parallel`** — 12 racers with distinct names, all succeed, each module's files distinct, lock map has 12 entries
+
+All run `flavor = "multi_thread", worker_threads = 4`.
+
+### Without the per-name lock (the bug it prevents)
+
+Two parallel callers with the same name and different params would:
+- Both call `target_dir.exists()` and see false
+- Both call `create_dir_all` (idempotent — both succeed)
+- Both write all 4 files in interleaved order
+- Last write wins per file → on-disk state has mod.rs from caller A + README.md from caller B (silent torn state)
+
+The friendly "already exists" error never fires; the corruption is silent.
+
+## Migration notes
+
+**No TS predecessor.** Designed fresh in Rust per the substrate doctrine. The generator's wire shape is the rethink — there was nothing to port.
+
+### v1 → v2 (PR #1487 → PR #1494)
+
+v1 produced 2 files (mod.rs + README.md) with raw-`Err` dispatch arms. Authors had to hand-author types.rs, the typed envelope wiring, the test module, the concurrency stress-test scaffold, and the DESIGN.md.
+
+v2 produces 4 files matching [the Module Design Template](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md). Author fills in ONE line per command (the Err body) + adds typed fields to Params/Result + writes the DESIGN.md prose. That's it.
+
+The v2 enrichment was driven by the substrate work in PRs #1485 (cell shapes) + #1486 (envelopes) + #1490–#1492 (concurrency doctrine). The generator now encodes those patterns automatically.
+
+## Kinks found
+
+1. **Same-name race silenced the friendly error.** Initial v1 impl had a race window between `exists()` check and `create_dir_all`. Two concurrent callers with the same name both passed the check, both created, both wrote — the "already exists" friendly error never fired. **Fix**: per-name `std::sync::Mutex` held across the entire exists/mkdir/write sequence (PR #1487 + concurrency test that caught it pre-merge).
+
+2. **Same-name race with force=true could torn-write.** Even with force, two concurrent racers' files could interleave (mod.rs from A, README from B). **Fix**: same per-name lock; force-mode writes serialize to ONE complete generation round per caller, with the second caller's writes overwriting the first cleanly. Pinned by the MARKER test.
+
+3. **v1's bare-`Err` dispatch carried no envelope wiring.** Every author writing a real handler had to convert raw `Err("not yet implemented")` arms into proper `CommandRequest::from_value` + typed handler + `CommandResponse::ok(...).into_command_result()`. **Fix in v2**: emit the envelope wiring + typed handler stubs directly — author only replaces the inner Err body.
+
+### Substrate refinements not needed yet
+
+The generator's surface is narrow (one command, four files emitted). It hasn't surfaced kinks that require new substrate primitives. If `generate/command` adds the "modify an existing module" pattern, AST-level parsing may surface design decisions (which Rust parser? `syn`? handwritten?) — flagged for then.

+# Genome, Foundry, Sentinel-AI: The Artifact-Sharing Economy On Consumer Hardware
+
+> **Substrate contract:** [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) — the runtime contract every Rust concern inherits. This document specifies the *artifact economy* that flows on top of that contract.
+> **Lane-shaped roadmap:** [ALPHA-GAP-ANALYSIS.md](../planning/ALPHA-GAP-ANALYSIS.md) — implementation lands per Lane H (Substrate Governor + Tiered Genome Cache) once the design here is reviewed.
+> **Status:** design proposal. No code in this document; every API shape shown is a proposed Rust trait targeted at `core/continuum-core/src/genome/`, `foundry/`, and `sentinel/`.
+
+## Why This Document Exists
+
+Continuum needs personas that **evolve**. Evolution happens through the **demand-aligned flow** of shared artifacts — commands, modules, personas, LoRA layers (with their MoE experts), long-term LoRA layers, and engrams — across the hive. The substrate that makes this real has to work on a MacBook Air (16 GB unified memory) and an RTX 5090 (32 GB VRAM + 64 GB system RAM) with the *same code path* — only the governor settings differ.
+
+The architecture that achieves both is the same architecture seen from two sides:
+
+- **The autonomy side**: an artifact-sharing economy. Personas are first-class entities; the genome is the shared substrate of evolved weights; the foundry brings in what others built; sentinel-AI refines what we lived; demand alignment is the routing principle.
+- **The efficiency side**: a classical computer-architecture toolbox. Persona = process. Genome = cache hierarchy. Engrams = paged virtual memory. Foundry = JIT compiler. Sentinel-AI = profile-guided optimizer. Substrate governor = DVFS.
+
+These are not two designs to merge later. They are one design seen from two angles. Any change to one half must be reflected in the other.
+
+This document specifies the substrate primitives, the Rust trait shapes, the hardware anchors, the lifecycle, and the acceptance criteria. It is written so that the next engineer can read it and start landing types in `continuum-core` without first writing more docs.

+## Part 1: Artifact Taxonomy

+Six durable artifact kinds flow through the genome pool. A seventh, transient kind, lives in the cache.
+
+| # | Artifact | Creator | Adopter | Refinement | Provenance |
+|---|---|---|---|---|---|
+| 1 | **Command** | continuum-core + module authors | every persona that calls the command | hot commands get specialized fast paths during sleep | author + version |
+| 2 | **Module** | engineers, scaffold generator | any cell registering with the runtime | sentinel can suggest module composition patterns; humans land them | engineer + commit |
+| 3 | **Persona** | user (via room creation) or another persona (via spawn) | the room; cross-room invocation by handle | sentinel refines persona's private LoRA + engrams from its traces | creator + lineage |
+| 4 | **LoRA layer** | foundry (imported) or sentinel (refined) or persona (private experimentation) | any persona via demand-aligned recall | sentinel re-refines hot layers from outcomes; foundry re-adapts when source SOTA updates | full chain — source SOTA → extraction → adaptation → refinement history |
+| 5 | **MoE expert** | foundry (imported) or sentinel (refined) | any persona's MoE routing table | sentinel observes which experts fire for good outcomes, re-routes | inherits from parent LoRA layer |
+| 6 | **Engram** | consolidation phase (from traces) or persona (explicit memory write) | the recalling persona; sentinel as training input | sentinel-derived clusters of engrams produce refined LoRA | trace ref + persona + time |
+
+The seventh, transient:
+
+7. **Composition state** — the dynamic LoRA stack + MoE routing + KV cache + engram-bound context that constitutes a persona's *currently-running* form. Not a stored artifact; recomputed from the genome pool on demand and cached at L1/L2. Lives only as long as it's hot.
+
+### Provenance Is Mandatory
+
+Every durable artifact carries a typed `Provenance` record. The substrate refuses to accept artifacts without one. Provenance is what makes trust auditable, refinement reversible, and sharing safe.
+
+```rust
+// PROPOSED — Lane H deliverable, targeted at core/continuum-core/src/genome/provenance.rs
+pub struct Provenance {
+    pub artifact_id: ArtifactId,                  // content hash
+    pub created_at: SystemTime,
+    pub creator: Creator,                          // Foundry | Sentinel | Persona | Human
+    pub source_trace: Vec<TraceRef>,               // traces this was derived from (empty for imports)
+    pub source_artifact: Vec<ArtifactRef>,         // upstream artifacts (e.g. base SOTA for foundry imports)
+    pub supersedes: Option<ArtifactRef>,           // previous version, if any
+    pub adaptation_method: AdaptationMethod,       // None | ExtractionAndQuantize | LoRARefine | EngramCluster | ...
+    pub outcome_metrics: Option<OutcomeMetrics>,   // attached when sentinel proves the artifact improves outcomes
+    pub trust_score: TrustScore,                   // composed from the rest
+    pub license: License,                          // inherited from source SOTA, or local
+}
+```
+
+If the substrate cannot answer "where did this LoRA layer come from and what proof do we have it works", the artifact is not in the pool. This is what `no_silent_fallback` looks like at the artifact economy layer.
+
+## Part 2: Cache Hierarchy
+
+The cache is a sequence of **tier roles** parameterized by hardware class. Discrete-GPU hardware has five distinct tiers; unified-memory hardware collapses the top two into one. The Rust code is identical across hardware; only the `Vec<TierConfig>` per-policy differs.
+
+> **Crit incorporated** from `claude-tab-1` (vHSM-scope, 2026-05-16): the v1 sketch used a fixed `L1..L5` enum. That's wrong on UMA hardware (M-series Macs, M5 Pro, iOS, Vision Pro, embedded) where the "L1 accelerator-resident" and "L2 system RAM" bytes are the same physical pool. An L1→L2 eviction is a no-op. The substrate code stays uniform; the tier count varies. Vision Pro and iOS will be UMA-class — locking 5-as-universal now would force a refactor when those land. This section now uses **tier roles**, not ordinal positions.
+
+### Tier Roles
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/tier.rs
+pub enum TierRole {
+    /// Bytes the accelerator can read at peak bandwidth.
+    /// Discrete GPU: VRAM. UMA: the hot portion of unified memory.
+    Fast,
+
+    /// Bytes the accelerator can reach with a copy or a tier-promotion.
+    /// Discrete GPU: host RAM (PCIe-attached, copy required to use).
+    /// UMA: same physical pool as Fast — this tier is omitted on UMA hardware.
+    Warm,
+
+    /// Bytes the host can read at memory speed; cold to the accelerator.
+    /// Discrete GPU + UMA: a designated portion of system RAM held for the
+    /// genome catalog + recently-used artifacts.
+    Bench,
+
+    /// Bytes on local SSD. The full genome pool lives here on every class
+    /// of hardware. Read latency is milliseconds; bandwidth is mmap-bound.
+    Cold,
+
+    /// Bytes on archive storage. Append-only with provenance preserved.
+    /// Reads are sub-second but never on the hot path. GC during sleep.
+    Frozen,
+}
+
+pub struct TierConfig {
+    pub role:        TierRole,
+    pub capacity:    TierCapacity,         // current_used, configured_limit
+    pub eviction:    EvictionPolicy,       // policy varies by role (see below)
+    pub backing:     TierBackingRef,       // implementation handle
+}
+
+pub trait TierStore: Send + Sync {
+    fn role(&self) -> TierRole;
+    async fn read(&self, page: PageRef) -> Result<PageHandle, TierError>;
+    async fn write(&self, page: PageRef, blob: ArtifactBlob, prov: Provenance) -> Result<(), TierError>;
+    async fn evict(&self, target_free_bytes: usize) -> Vec<EvictionRecord>;
+    fn capacity(&self) -> TierCapacity;
+    fn observe_access(&self, page: PageRef);
+}
+```
+
+The governor's policy file (Part 11) declares a `Vec<TierConfig>` — typically four entries on UMA hardware, five on discrete-GPU hardware. Subsystems index into the vec by `TierRole`, not by ordinal position. Page-fault reports name the source and destination by role:
+
+```rust
+pub struct PageFault {
+    pub page:          PageRef,
+    pub from_role:     Option<TierRole>,   // None = true cold miss (page does not exist yet)
+    pub to_role:       TierRole,
+    pub persona:       PersonaId,
+    pub elapsed_us:    u64,
+    pub eviction_cost: Option<EvictionRecord>,
+}
+```
+
+### Eviction Policy Per Role
+
+| Role | Policy | When eviction fires |
+|---|---|---|
+| `Fast` | LRU within current turn | sub-step needs a page not resident |
+| `Warm` (discrete-GPU only) | LRU across last N turns (governor sets N; default 100) | `Fast` spill |
+| `Bench` | LFU + recency; broad-use pages get retention bonus | `Warm` spill (discrete) or `Fast` spill (UMA) |
+| `Cold` | Demand-aligned with sentinel-refined preference (refined wins ties over imported) | `Bench` spill |
+| `Frozen` | Append-only with provenance preserved; GC only during sleep | never in hot path |
+
+Eviction is *always* typed: every evicted page emits an `EvictionRecord` to the trace bus. Recurring evictions of the same page across turns are exactly the signal sentinel uses to upgrade the page's tier policy.
+
+### Hardware Anchors
+
+Two anchor configurations; everything else interpolates. The substrate *detects* the hardware class at boot and the governor writes a `Vec<TierConfig>` of the right shape. **On UMA hardware, `Warm` is omitted** — the vec has four entries; an `Fast`→`Warm` eviction is structurally absent because there is no separate `Warm` tier to evict to.
+
+**MacBook Air, M-series, 16 GB unified memory** — UMA-class, four tiers:
+
+```
+[ Fast(2 LoRA layers + 2k KV tokens; LRU-within-turn)
+, Bench(12 layers + ~1k engrams; LFU + recency)
+, Cold(SSD genome pool; demand-aligned, sentinel-refined preferred)
+, Frozen(longterm.db; append-only, GC during sleep)
+]
+```
+
+**RTX 5090, 32 GB VRAM + 64 GB system RAM** — discrete-GPU, five tiers:
+
+```
+[ Fast(8 LoRA layers + 16k KV tokens; LRU-within-turn)
+, Warm(16 layers; LRU across last 100 turns)
+, Bench(40+ layers + ~10k engrams; LFU + recency)
+, Cold(SSD genome pool; demand-aligned, sentinel-refined preferred)
+, Frozen(longterm.db; append-only, GC during sleep)
+]
+```
+
+Other axes that vary per anchor:
+
+| | **Air (UMA, 4 tiers)** | **5090 (discrete, 5 tiers)** |
+|---|---|---|
+| Concurrent personas | 1–2 | 6–8 |
+| Speculative composition | conservative (only on idle slack) | aggressive (every turn) |
+| Sleep / consolidation cadence | nightly, opportunistic on idle/plugged-in | nightly + partial during day |
+| Cross-instance federation pull | manual / explicit | automatic on idle |
+
+M-Pro/Max are UMA-class with larger pools (still four tiers, bigger numbers). Discrete AMD/Intel via Vulkan match the 5090 shape with smaller numbers. Vision Pro and iOS are UMA-class with aggressive eviction + reduced concurrency + simpler composition (still four tiers; the `Warm` role is structurally absent, not just configured to zero). Embedded targets may drop to three tiers (`Fast`, `Cold`, `Frozen`) if `Bench` would compete with foreground responsiveness.
+
+**The Rust code is identical across all of them.** The architectural beauty: subsystems address tiers by role, the governor writes a `Vec<TierConfig>` of the right length, and the type system makes "L1→L2 eviction on UMA" structurally impossible because there is no `Warm` tier to evict to.
+
+## Part 3: Paging, Working Set, And Page Faults
+
+A persona's `WorkingSet` is the set of pages currently hot in L1+L2 for that persona. Pages can be LoRA layer pages, MoE expert pages, KV cache pages, or engram pages.
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/working_set.rs
+pub struct WorkingSet {
+    pub persona: PersonaId,
+    pub pages: HashMap<PageRef, ResidentPage>,
+    pub capacity: WorkingSetCapacity,              // from governor
+    pub last_composition: Option<CompositionPlan>,
+}
+
+pub struct ResidentPage {
+    pub page: PageRef,
+    pub role: TierRole,                            // Fast (or Warm on discrete-GPU hardware)
+    pub last_access: Instant,
+    pub access_count_window: u32,
+    pub pinned: bool,                              // composition-pinned pages cannot evict mid-turn
+}
+
+pub enum PageKind { LoRALayer, MoEExpert, KVCache, Engram }
+
+pub struct PageRef {
+    pub kind: PageKind,
+    pub artifact: ArtifactId,
+    pub offset: PageOffset,                        // for sub-artifact paging (MoE experts, KV chunks)
+}
+```
+
+When the persona's composition needs a page not in its working set, that's a **page fault** (the typed struct is defined in Part 2 alongside `TierRole`):
+
+```rust
+pub trait WorkingSetManager: Send + Sync {
+    /// Promote a page into this persona's working set. May trigger eviction.
+    async fn page_in(&self, persona: PersonaId, page: PageRef) -> Result<PageHandle, PageFault>;
+
+    /// Demote a page out of the working set toward the named tier role.
+    async fn page_out(&self, persona: PersonaId, page: PageRef, to: TierRole) -> Result<(), TierError>;
+
+    /// Current working set for read-only inspection.
+    fn working_set(&self, persona: PersonaId) -> &WorkingSet;
+
+    /// Enforced MMU-style audit: persona is asking for a page.
+    /// Returns AccessDenied if the page is private to another persona.
+    fn audit_access(&self, persona: PersonaId, page: PageRef) -> Result<(), AccessDenied>;
+}
+```
+
+Page faults are **typed events** on the trace bus. Sentinel observes them. A persona that page-faults on the same page across many turns is a signal to either pre-fetch that page (raise speculation aggressiveness for it) or upgrade its tier policy (pin it higher in the working set).
+
+This is the substrate's main observability signal for "this persona's working set doesn't match what we're allocating." It is the difference between a substrate that knows what's wrong and one that doesn't.
+
+## Part 4: Compartmentalization
+
+Personas are processes. Each has:
+
+- An independent inbox (per the CBAR-SUBSTRATE "Persona-cognition invariants")
+- An independent KV cache
+- An independent `WorkingSet`
+- An independent composition state
+- An independent mood / energy / cadence state
+- An independent private engram region
+
+The **genome pool is a shared library** mapped read-only into every persona's address space. Write access is segmented:
+
+| Region | Foundry | Sentinel-AI | Persona (self) | Persona (other) |
+|---|---|---|---|---|
+| Imported (foundry-adapted) | write | read | read | read |
+| Refined (sentinel-derived) | read | write | read | read |
+| Own private engrams | read | read (training only, opt-in) | write | none |
+| Own private LoRA experiments | read | read (training only, opt-in) | write | none |
+| Other persona's private | none | read (training only, opt-in) | none | none |
+
+```rust
+pub trait WorkingSetManager {
+    // ... continues from above
+    /// Enforce MMU-style permissions. Returns typed AccessDenied with full context
+    /// — never silently succeeds, never silently fails.
+    fn check_permission(
+        &self,
+        actor: ActorId,
+        region: GenomeRegion,
+        op: Op,
+    ) -> Result<(), AccessDenied>;
+}
+```
+
+`AccessDenied` is loud. Audit log captures it. This is how the substrate makes per-persona privacy structural rather than policy.
+
+## Part 5: Foundry — JIT For Models
+
+The foundry is the only substrate component that *imports* artifacts from outside Continuum. It is the JIT in the same sense that Java's HotSpot is a JIT: it compiles the *source* (SOTA model) into the *binary* (our adapted format) that the runtime actually executes.
+
+```rust
+// PROPOSED — core/continuum-core/src/foundry/mod.rs
+pub trait Foundry: Send + Sync {
+    /// Pull a SOTA source and extract useful artifacts.
+    /// Runs out-of-band; never blocks any persona's hot path.
+    async fn absorb(&self, source: &SOTASource) -> Result<AbsorptionReport, FoundryError>;
+
+    /// Iterate over imported artifacts published by this foundry.
+    fn iter_imports(&self) -> Box<dyn Iterator<Item = ImportedArtifact> + '_>;
+
+    /// Re-absorb when the source SOTA updates; emits supersession records.
+    async fn refresh(&self, source: &SOTASource) -> Result<AbsorptionReport, FoundryError>;
+}
+
+pub struct SOTASource {
+    pub model: ModelIdentifier,                    // qwen3-32b-instruct, mistral-large, ...
+    pub version: String,
+    pub fetch: FetchMethod,                        // HF | local file | API | ...
+    pub license: License,
+    pub trust_class: TrustClass,                   // open-weight | foundation-vendor | community | ...
+}
+
+pub struct ImportedArtifact {
+    pub kind: ImportedKind,                        // BaseModel | LoRALayer | MoEExpert | EmbeddingShard | ...
+    pub source: SOTASource,
+    pub extraction: ExtractionMethod,              // FullModel | LayerSubset | ExpertExtraction | DistillationTarget
+    pub format: ContinuumArtifactFormat,           // our quantization + LoRA-on-base shape
+    pub blob: ArtifactBlob,
+    pub provenance: Provenance,
+}
+```
+
+The foundry does five things:
+
+1. **Acquisition** — pull SOTA model weights (Qwen, Mistral, others, future).
+2. **Extraction** — pull only the parts the genome needs. Not the whole model; specific layers, specific experts, specific embedding shards.
+3. **Adaptation** — quantize for our hardware classes; shape into LoRA-on-base; ensure compatibility with the base + composition layer.
+4. **Provenance** — every output artifact gets metadata: which SOTA, which version, which extraction method, what license, what trust class.
+5. **Publication** — the adapted artifact lands in the *imported* tier of the genome pool. Demand-aligned recall starts considering it.
+
+The foundry runs in a `Background` `ResourceClass` lane. It never blocks persona hot paths. When a new SOTA arrives, the foundry recompiles; existing personas keep running on the previous binary until normal page-fault + LRU pressure migrates them forward. Migration is **explicit** (logged, replayable, reversible) — never silent.
+
+### Why The Foundry Is Substrate, Not An External Service
+
+The foundry could in principle be a separate process pulling SOTA models, adapting them, and dropping files on disk for Continuum to pick up. It is *not* designed that way, because:
+
+- **Provenance must be in-substrate.** A separate service produces files; the substrate has no way to refuse files with missing provenance. In-substrate, the type system enforces `Provenance` is mandatory.
+- **Adaptation is hardware-aware.** The right quantization depends on the target's hardware class. The substrate already knows the hardware class via the governor. An external service would have to re-derive it.
+- **Federation needs same shape.** If federated hives share foundry-imported artifacts, they must have identical adaptation pipelines. Centralizing in-substrate means the adaptation is the same everywhere or the artifact is incompatible — clear failure mode, no silent drift.
+
+## Part 6: Sentinel-AI — Profile-Guided Optimization
+
+Sentinel-AI is Continuum's **custom experiential model** — distinct from the foundry's imports. It is where lived experience crystallizes into weights. The foundry brings in *what others built*. Sentinel produces *what we lived*.
+
+```rust
+// PROPOSED — core/continuum-core/src/sentinel/mod.rs
+pub trait SentinelAI: Send + Sync {
+    /// Stream traces into the sentinel for outcome attribution.
+    /// Cheap; runs continuously.
+    async fn observe(&self, trace: &CognitionTrace) -> Result<(), SentinelError>;
+
+    /// Trigger a refinement pass. Runs during sleep / consolidation.
+    /// Reads accumulated traces, attributes outcomes, retrains where it has signal.
+    async fn refine_pass(&self) -> Result<RefinementReport, SentinelError>;
+
+    /// Read-only attribution: what contributed to this turn's outcome?
+    fn attribute(&self, trace: &CognitionTrace) -> Vec<ArtifactAttribution>;
+
+    /// Iterate over refined artifacts this sentinel has produced.
+    fn iter_refined(&self) -> Box<dyn Iterator<Item = RefinedArtifact> + '_>;
+}
+
+pub struct CognitionTrace {
+    pub trace_id: TraceId,
+    pub persona: PersonaId,
+    pub frame: RuntimeFrameRef,
+    pub composition: CompositionPlan,              // what was hot for this turn
+    pub recall_results: Vec<RecallResult>,         // what demand-aligned recall returned
+    pub output: PersonaOutput,
+    pub outcome: Option<Outcome>,                  // attached later when feedback arrives
+}
+
+pub struct RefinedArtifact {
+    pub kind: RefinedKind,                         // LoRALayer | MoEExpert | EngramCluster | RoutingTable
+    pub supersedes: Option<ArtifactRef>,
+    pub source_traces: Vec<TraceRef>,
+    pub attribution: OutcomeAttribution,
+    pub blob: ArtifactBlob,
+    pub provenance: Provenance,
+}
+```
+
+Sentinel does, in order:
+
+1. **Trace consumption.** Every cognition trace flows into sentinel via `observe`. Cheap; the trace is already on the bus, sentinel reads it as a subscriber.
+2. **Outcome attribution.** When a trace gets an outcome (user signal, downstream classifier, persona's own retrospective), sentinel attributes that outcome back to the artifacts that contributed — which LoRA layers were composed, which experts fired, which engrams were recalled.
+3. **Refinement passes.** During sleep, sentinel retrains. Hot LoRA layers get tightened from traces that used them well. MoE expert routing tables get refined based on which experts fired when outcomes were good. New engrams get generated from clusters of trace patterns.
+4. **Publication.** Refined artifacts land in the *refined* tier of the genome pool with full provenance: which traces, which outcomes, which previous artifact version this supersedes.
+5. **Adoption.** Demand-aligned recall (next section) starts picking the refined artifact for relevant queries because it scores higher on outcome-conditioned similarity. Old compositions invalidate naturally as their personas next page-fault.
+
+### Local-First, Then Federated
+
+Two design choices that shape the rest of the architecture:
+
+- **Sentinel is local first.** Each instance / machine runs its own sentinel against its own traces. Refined artifacts publish locally before federating. This keeps privacy simple (traces never leave the machine unless explicitly shared) and latency tight (sentinel runs on the same hardware that produced the traces).
+- **One sentinel per instance, not per persona.** A single sentinel sees the cross-persona patterns within an instance. Per-persona sentinels would miss the signal that *is* hive evolution. Federation happens at a coarser grain (sentinel-derived artifacts can be published cross-instance with provenance + opt-in).
+
+## Part 7: Demand-Aligned Recall
+
+The substrate's *default lookup* is not "load adapter by name." It is "I need help with this; give me a ranked pool I can compose from." Recall is the single most-used substrate primitive in this design and the place where consumer-hardware federation either earns its keep or doesn't — every cell touches it, every turn, and the ingenuity of how it spans local cache → cross-instance grid → federated peers is what makes the underdog architecture competitive.
+
+### Trait Surface
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/recall.rs
+pub trait DemandAlignedRecall: Send + Sync {
+    /// The hot-path lookup. Sub-ms target on local L1/L2 hits; grid-aware
+    /// budget when results must come from a peer or federation pull.
+    async fn recall(
+        &self,
+        query: &CapabilityQuery,
+        context: &PersonaContext,
+    ) -> Result<RankedPool, RecallError>;
+
+    /// Replay a previous recall deterministically from its trace record.
+    /// Used by sentinel for outcome attribution and by VDD for regression

+    /// using snapshotted scoring weights + artifact set at that time.
+    async fn replay(
+        &self,
+        trace: &RecallTrace,
+    ) -> Result<RankedPool, RecallError>;
+}
+
+pub struct CapabilityQuery {
+    pub task_kind:        TaskKind,                // Chat | Code | Vision | ToolUse | Memory | Plan | ...
+    pub domain_hints:     Vec<DomainHint>,         // free-form tags from the persona's plan
+    pub budget:           ResourceBudget,          // memory + time budget for the composition
+    pub must_include:     Vec<ArtifactRef>,        // hard pins (persona-private LoRA, sticky engrams)
+    pub prefer_refined:   bool,                    // default true; sentinel-refined > foundry-imported
+    pub scope:            RecallScope,             // Local | LocalThenGrid | Federation { ... }
+    pub freshness_target: FreshnessTarget,         // BestEffort | FreshAsOf(ts) | Strict
+}
+
+pub struct PersonaContext {
+    pub persona:                 PersonaId,
+    pub current_composition:     Option<CompositionRef>,   // what's already hot
+    pub recent_outcomes:         OutcomeWindow,            // last N turns of outcomes (sentinel input)
+    pub conversation_trajectory: TrajectoryHint,           // for speculative weight on probable next-task
+    pub trust_overrides:         Vec<(PeerId, TrustClass)>,// user-explicit trust adjustments
+}
+
+pub struct RankedPool {
+    pub layers:           Vec<(LoRALayerRef,  RecallScore, ResidencyHint)>,
+    pub experts:          Vec<(MoEExpertRef,  RecallScore, ResidencyHint)>,
+    pub engrams:          Vec<(EngramRef,     RecallScore, ResidencyHint)>,
+    pub composition_hint: CompositionHint,         // suggested stack order + weights
+    pub trace_ref:        RecallTrace,             // sentinel + VDD replay handle
+}
+
+pub enum RecallScope {
+    Local,                                          // never leave this machine
+    LocalThenGrid { max_grid_pulls: usize },        // local first; grid pulls bounded
+    Federation { peers: Vec<PeerId>, max_latency_ms: u32 },
+}
+
+pub enum ResidencyHint {
+    Hot { role: TierRole },                         // already Fast (or Warm on discrete-GPU)
+    Local { role: TierRole },                       // Bench / Cold / Frozen on this machine; promotable
+    GridPeer { peer: PeerId, est_latency_ms: u32 }, // resident on a federated peer
+    NotResident { acquirable_from: AcquireSource }, // foundry would have to import or sentinel refine
+}
+```
+
+`ResidencyHint` is the load-bearing addition: the persona doesn't just see *what's relevant*, it sees *where it lives* and *what it costs to use*. A persona on a MacBook Air running tight on VRAM can pick the local L3 layer over a slightly-higher-scoring layer on a peer's 5090 — because the scoring already incorporates `tier_proximity`, but the explicit `ResidencyHint` lets the persona make the cost trade-off visibly.
+
+### The Scoring Function — Explicit, Tunable, Sentinel-Refined
+
+The combined score is a weighted sum, but the weights are dynamic — governor-tunable per hardware class and sentinel-refined per persona over time. The base function is intentionally simple so its behavior is auditable:
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/recall/scoring.rs
+pub fn score(
+    artifact: &ArtifactCandidate,
+    query:    &CapabilityQuery,
+    ctx:      &PersonaContext,
+    weights:  &RecallScoreWeights,

+    let tier_proximity   = match artifact.residency {
+        ResidencyHint::Hot   { .. }           => 1.0,
+        ResidencyHint::Local { role }         => local_role_score(role),

+        //                                       Cold   ≈ 0.3
+        //                                       Frozen ≈ 0.1
+        ResidencyHint::GridPeer { est_latency_ms, .. } => grid_penalty(est_latency_ms),
+        ResidencyHint::NotResident { .. }     => 0.0,
+    };
+    let provenance_trust = trust_score(artifact.provenance, ctx.trust_overrides);
+
+    let combined =
+          weights.semantic         * semantic
+        + weights.outcome_history  * outcome_history
+        + weights.recency          * recency
+        + weights.tier_proximity   * tier_proximity
+        + weights.provenance_trust * provenance_trust;
+
+    RecallScore { semantic, outcome_history, recency, tier_proximity, provenance_trust, combined }
+}
+```
+
+Each factor has a clean definition:
+
+- **`semantic`** is cosine similarity between query embedding and artifact metadata embedding. The embedding model is itself a foundry-imported artifact in v1 (bootstrap), sentinel-refined in v2 (Open Question 2 in this doc).
+- **`outcome_history`** scores how well this artifact performed in the persona's last N turns of similar tasks. `outcome_window_score` is exponentially-decayed weighting of explicit outcomes (user signal) and implicit outcomes (downstream tool success, conversation continuation length).
+- **`recency`** is exponential decay over time-since-last-use. Half-life is governor-tunable; default 24h.
+- **`tier_proximity`** penalizes cost-to-promote. Hot artifacts score 1.0; cold archive scores 0.2; grid peers score a function of estimated latency (see `grid_penalty` below).
+- **`provenance_trust`** is the artifact's trust score adjusted by the persona's trust overrides. Sentinel-refined-locally > sentinel-refined-by-trusted-peer > foundry-imported > anonymous-public.
+
+`grid_penalty(latency_ms)` is the load-bearing cost function for federated recall:
+
+```rust
+fn grid_penalty(est_latency_ms: u32) -> f32 {
+    // Same-LAN peer (< 10 ms):   ~0.55  — slightly worse than local L3
+    // Same-region (< 50 ms):     ~0.35
+    // Cross-region (< 200 ms):   ~0.15
+    // Slow / unreliable:         ~0.05
+    0.6 * (-(est_latency_ms as f32 / 100.0)).exp()
+}
+```
+
+The penalty is *steep* — a peer's slightly-better artifact has to be substantially better to overcome the latency cost. This is the architectural choice: on consumer hardware, **a hot local L3 hit usually wins**, and that's why a federated swarm of MacBook Airs can compete with a single datacenter — the swarm's local cache wins on latency, the swarm's diversity wins on coverage, and the substrate's recall makes both visible to the persona without it having to know the topology.
+
+### Dynamic Weights — Governor And Sentinel Both Tune
+
+`RecallScoreWeights` is part of `GovernorPolicy` (Part 11). The governor sets it per hardware class:
+
+```toml
+[recall_weights]
+# Air: cache locality matters more (smaller hot set)
+semantic         = 0.40
+outcome_history  = 0.30
+recency          = 0.10
+tier_proximity   = 0.15
+provenance_trust = 0.05
+
+[recall_weights]
+# 5090: semantic match matters more (room to hold more artifacts hot)
+semantic         = 0.50
+outcome_history  = 0.20
+recency          = 0.10
+tier_proximity   = 0.05
+provenance_trust = 0.15
+```
+
+Sentinel observes which `recall → composition → outcome` chains produced good results and refines the weights *per persona over time*. A persona that consistently does better with sentinel-refined artifacts than foundry-imported ones gets a higher local `provenance_trust` weight. A persona that does better with semantically-distant-but-recently-used artifacts gets higher `recency`. This is profile-guided optimization of the recall function itself.
+
+Sentinel writes its refinements to the governor as `RecallScoreWeights` updates with provenance. The governor applies them per persona (the policy carries a per-persona override table) and they propagate through the normal `arc_swap`-published policy. Sentinel-refined recall weights are also a publishable artifact in the genome pool — federated peers can adopt another instance's weights with the usual `provenance_trust` gating.
+
+### Indexing — Sub-ms Local, Coordinated Grid
+
+The recall index is a layered structure:
+
+| Layer | Purpose | Backed by | Lookup cost |
+|---|---|---|---|
+| Working-set index | "is this artifact ref hot for this persona right now" | `HashMap<PersonaId, BTreeSet<ArtifactRef>>` | O(log n), in-memory |
+| Local catalog | All artifacts in tiers L1–L5 with embeddings + metadata | sqlite + on-disk ANN index (hnsw) over embeddings | < 1 ms for top-K |
+| Grid catalog | Federated peers' artifact summaries (id + embedding + provenance + last_seen) | gossip-propagated via the sharing protocol | < 5 ms cached; cross-peer fetch if cold |
+| Federation catalog | The broader hive (opt-in) | pull-based, governor-rate-limited | bounded by `federation_pull_cadence` |
+
+A recall query touches the layers in order. The first that satisfies the budget + freshness target wins. Most queries return from the local catalog (or even the working-set index for repeat-within-turn queries). Grid + federation catalogs are consulted only when the local set is insufficient or when the persona's `RecallScope` explicitly asks for them.
+
+### Within-Turn Caching And Coalescing
+
+A persona doing one turn often issues multiple recalls — initial context-gather, then re-recall after a tool-use, then again for response composition. These should not re-execute the full pipeline:
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/recall/cache.rs
+pub struct WithinTurnRecallCache {
+    persona:    PersonaId,
+    turn_id:    TurnId,
+    by_query:   HashMap<QueryFingerprint, Arc<RankedPool>>,
+    in_flight:  HashMap<QueryFingerprint, BroadcastReceiver<Arc<RankedPool>>>,
+}
+```
+
+Two behaviors:
+
+1. **Memoization within the turn.** Identical `CapabilityQuery` from the same persona in the same turn returns the cached `RankedPool` immediately. Cleared when the turn frame is released.
+2. **Coalescing of concurrent identical queries.** If two cells in the same persona's turn issue the same query milliseconds apart, the second one subscribes to the first's in-flight `BroadcastReceiver` rather than re-executing.
+
+Across personas, similar queries may not be identical (different `must_include` pins, different `PersonaContext`) so cross-persona coalescing is at the *sub-query* level: the embedding generation step coalesces (one embed call per unique query text), the catalog lookup step coalesces (one ANN query per unique embedding), the scoring step does not (each persona's `PersonaContext` differs).
+
+### Cross-Instance Recall — The Grid Coordination Layer
+
+When a recall's `RecallScope` is `LocalThenGrid` and the local catalog doesn't satisfy the budget, the substrate consults the grid. This is the ingenuity layer — the federated swarm has to coordinate without becoming a chatter storm.
+
+Three rules:
+
+1. **No instance queries the grid more often than its `federation_pull_cadence` allows.** Set per-hardware-class by the governor: Air ≈ once per 10 minutes; 5090 ≈ once per minute. This is the same cadence that publishes new artifacts; pull and push share a budget.
+2. **Grid catalog is gossip-propagated, not query-on-demand.** Each instance publishes its artifact summaries (not the artifact blobs) on its `federation_pull_cadence`. Other instances cache the summaries. A recall query against the grid catalog hits the *local cache of the gossip*, not the live peer — sub-ms latency for what would otherwise be a multi-hop network query.
+3. **Fetching a grid artifact blob requires explicit promotion.** A `RecallResult` containing a `ResidencyHint::GridPeer` does *not* fetch the blob until the persona's composition pins it. The substrate pulls the blob into the local L4 with provenance preserved; subsequent recalls find it locally.
+
+The win condition: **a swarm of Airs gossiping summaries every 10 minutes produces a federated artifact catalog that's effectively realtime for the recall scoring function**, because the scoring function uses the cached summary, not the live blob. Only on pin does the blob move. This is how the architecture stays performant on cellular-class bandwidth while still letting the swarm coordinate at the level of "what exists, what's been refined, what's been retired."
+
+### Replay Semantics
+
+Sentinel attribution and VDD regression both require replaying a previous recall and getting the same `RankedPool`. The trait's `replay(trace)` method does this:
+
+```rust
+pub struct RecallTrace {
+    pub trace_id:           TraceId,
+    pub query:              CapabilityQuery,            // snapshot at recall time
+    pub context_snapshot:   PersonaContextSnapshot,     // snapshot at recall time
+    pub policy_version:     u64,                        // governor policy at recall time
+    pub catalog_snapshot:   CatalogSnapshotRef,         // content-hashed; deterministic replay
+    pub timestamp:          SystemTime,
+    pub returned_pool:      RankedPool,                 // for outcome attribution
+}
+```
+
+A replay re-runs `score()` over the snapshotted catalog with the snapshotted weights. The result is deterministic and bit-equal to the original `returned_pool`. Sentinel uses this to attribute "did the artifact I refined actually win the ranking on the turn it should have?" — without it, sentinel can't tell the difference between "my refinement helped" and "the artifact I refined just happened to be hot when it ran."
+
+### Recall Under Pressure
+
+The governor's cascade (Part 11) affects recall in defined ways:
+
+| Cascade step | Effect on recall |
+|---|---|
+| 0 (normal) | full pipeline; grid + federation as requested |
+| 1 | speculation deprioritized; recall returns slightly smaller pools (top-K reduced) |
+| 2 | grid pulls deferred unless `RecallScope::Federation` explicit; otherwise local-only |
+| 3 | working-set index is the only fast layer; ANN index falls back to higher-error / faster K |
+| 4 | federation pulls suspended; grid catalog stale-served |
+| 5 | recall caps at L1+L2 only; cold-archive lookups return `Deferred(MemoryPressure)` |
+
+Recall under pressure is *correct* — it doesn't lie, doesn't return placeholders. It returns smaller, more-conservative pools with explicit `ResidencyHint::Deferred` entries when an artifact exists but can't safely be promoted. The persona's composer sees this and either narrows its composition or defers the turn — never silently degrades.
+
+### Performance Budget
+
+Recall is in the hot path. The budget is tight:
+
+| Operation | Air target | 5090 target |
+|---|---|---|
+| Within-turn cache hit | < 50 μs | < 30 μs |
+| Working-set index hit | < 200 μs | < 100 μs |
+| Local catalog (ANN top-K) | < 5 ms | < 2 ms |
+| Grid catalog (cached gossip) | < 5 ms | < 5 ms |
+| Federation catalog (cached) | < 10 ms | < 10 ms |
+| Federation pull (cold) | bounded by `federation_pull_cadence`, off hot path |
+
+The first three rows cover ≥ 95% of recalls. The substrate's acceptance criteria includes a smoke test that verifies P50/P99 against these budgets on both anchors.
+
+### Why This Earns Its Space In The Doc
+
+Recall is where the architecture wins or loses on consumer hardware. A naive recall that hit GitHub or HuggingFace for every query would make the system unusable on cellular bandwidth. A purely local recall would forfeit the federation's collective intelligence. The substrate's win is that recall is **local-first, gossip-aware, sentinel-refined, governor-tuned, cost-visible to the persona, and deterministic in replay** — five properties that together let an Air running solo, a 5090 running solo, and a swarm of Airs + 5090s all use the same Rust code path and all benefit from each other's evolved genome. That's the dynamicism-across-the-grid claim made concrete.
+
+## Part 8: Composition
+
+A persona's effective model at any moment is a **dynamic composition** of base + tiered LoRA + MoE expert routing + engram-conditioned context. Composition is recomputed when the task / context / pressure shifts; otherwise the substrate caches it.
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/composition.rs
+pub struct CompositionPlan {
+    pub base_model: BaseModelRef,
+    pub lora_stack: Vec<LoRAComposition>,
+    pub moe_routing: MoERoutingTable,
+    pub kv_cache_budget: usize,
+    pub engram_context: Vec<EngramRef>,
+    pub provenance: CompositionProvenance,         // what query produced this; what was hot at the time
+}
+
+pub struct LoRAComposition {
+    pub layer: LoRALayerRef,
+    pub weight: f32,                               // composition weight
+    pub role_at_plan: TierRole,                    // which tier role this layer occupied when planned
+}
+
+pub trait Composer: Send + Sync {
+    /// Build a composition from a ranked pool + persona constraints.
+    fn compose(
+        &self,
+        pool: &RankedPool,
+        constraints: &CompositionConstraints,
+    ) -> Result<CompositionPlan, CompositionError>;
+
+    /// Materialize a plan: ensure all referenced pages are at least L2-resident,
+    /// pin them for the duration of the turn.
+    async fn materialize(
+        &self,
+        plan: &CompositionPlan,
+        persona: PersonaId,
+    ) -> Result<MaterializedComposition, CompositionError>;
+}
+```
+
+The composition is the **binary** the persona executes. The genome pool is the *library* it links against. The composer is the *linker* — it picks which library entries land in the binary for this turn, weighted, pinned, and budgeted.
+
+## Part 9: Speculative Pre-Composition
+
+While a persona's current turn is running, the substrate pre-composes the *likely-next* plan and pre-fetches the *likely-next* pages based on conversation trajectory, persona's historical patterns, recent page faults, and branch hints from the turn frame.
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/speculation.rs
+pub struct SpeculativeBranch {
+    pub trigger: TurnTrajectoryHint,               // "user is about to ask follow-up X"
+    pub composition: CompositionPlan,
+    pub pre_fetch: Vec<PageRef>,
+    pub confidence: f32,                           // how strongly we expect this branch
+}
+
+pub trait Speculator: Send + Sync {
+    /// Generate speculative branches given current turn state.
+    fn branches(&self, current: &TurnState) -> Vec<SpeculativeBranch>;
+
+    /// Materialize branches up to the governor's speculation budget.
+    async fn pre_materialize(&self, branches: &[SpeculativeBranch]) -> Result<(), SpeculationError>;
+
+    /// Discard branches that did not match the actual next turn.
+    async fn discard(&self, kept: &CompositionPlan, branches: &[SpeculativeBranch]);
+
+    /// Hit-rate tracking for governor feedback.
+    fn hit_rate(&self) -> HitRateSnapshot;
+}
+```
+
+If speculation hits, the next turn has near-zero composition latency. If it misses, speculative pages get evicted as normal LRU — *no penalty*. The substrate tracks hit rate per persona and per branch class, and the governor tunes aggressiveness based on it.
+
+On a MacBook Air, the governor sets speculation conservative — only on idle slack, single-branch only, and only when L3 has headroom. On a 5090, the governor sets it aggressive — multi-branch, every turn, even when L2 is full (because L2 eviction is cheap there).
+
+## Part 10: Sharing Protocol — Global-Scale Hive
+
+Sentinel-refined and foundry-adapted artifacts are publishable to the broader hive. Cross-room, cross-instance, optionally cross-user (with consent + provenance). Other personas pull and integrate.
+
+```rust
+// PROPOSED — core/continuum-core/src/genome/sharing.rs
+pub trait SharingProtocol: Send + Sync {
+    /// Publish an artifact to the configured federation scope.
+    async fn publish(
+        &self,
+        artifact: &PublishableArtifact,
+        scope: FederationScope,
+    ) -> Result<PublicationReceipt, SharingError>;
+
+    /// Pull federation updates. Returns artifacts new since the last pull.
+    async fn pull(&self, since: PullCursor) -> Result<Vec<FederatedArtifact>, SharingError>;
+
+    /// Trust-class lookup: how much do we trust this peer's artifacts?
+    fn trust_for(&self, peer: PeerId) -> TrustClass;
+}
+
+pub enum FederationScope {
+    LocalInstance,                                 // never leaves this machine
+    Trusted { peers: Vec<PeerId> },                // explicit peer list
+    Federation { network: FederationId },          // a named federation
+    Public,                                        // open hive — provenance + trust required
+}
+```
+
+Coherency is **eventual consistency with provenance**. Not MESI. Not locks. When a peer publishes a refined LoRA layer, it goes into the federated pool with provenance attached. Demand-aligned recall starts picking it up because it scores higher on similar queries (subject to trust-class weighting). Old compositions invalidate naturally as their personas next page-fault. Global-scale consistency by demand alignment, not by coordination.
+
+This is the architectural answer to "evolution on a global scale." The hive evolves *as a collective* because the highest-scoring artifacts for any given query propagate through the network organically. No central authority. No lockstep. Just demand alignment + provenance.
+
+### Trust And Adoption
+
+A federated artifact is not blindly trusted. The recall scoring weight on `provenance_trust` is what gates adoption:
+
+- Sentinel-refined locally > sentinel-refined from a trusted peer > sentinel-refined from a known federation > anonymous public artifact.
+- Foundry-imported from a foundation vendor > foundry-imported community model.
+- An artifact failing local sentinel attribution (it gets recalled, but consistently produces worse outcomes than what it superseded) gets its trust score automatically demoted, and the supersession is reverted.
+
+Trust is *learned*, not declared. This is what makes the federation safe at scale.
+
+## Part 11: The Substrate Governor
+
+The governor is the DVFS layer for the AI substrate. It is the one Rust subsystem that makes "same code on MacBook Air and RTX 5090" real: detect the hardware at boot, write the policy file, expose a read-only `current_policy()` to every other subsystem, adjust at runtime under pressure, and reverse cleanly when pressure releases. Every other subsystem in this document — tier stores, recall, composer, speculator, foundry, sentinel, sharing protocol — reads the governor and never writes back. The governor *is* the single source of truth for sizing.
+
+### Trait Surface
+
+```rust
+// PROPOSED — core/continuum-core/src/governor/mod.rs
+pub trait SubstrateGovernor: Send + Sync {
+    /// Current policy. Cheap read: returns Arc to immutable snapshot, so
+    /// callers can hold without contention. Policy is rewritten under
+    /// pressure, never mutated in place.
+    fn current_policy(&self) -> Arc<GovernorPolicy>;
+
+    /// Called once at boot, and any time hardware changes (eGPU plug,
+    /// power source change, thermal class change). The probe sequence
+    /// is in §"Hardware Detection" below.
+    fn on_hardware_detected(&self, hw: HardwareClass);
+
+    /// Called by PressureBroker (CBAR-SUBSTRATE) when a typed pressure
+    /// signal crosses a threshold. Governor decides whether to step the
+    /// cascade, hold, or reverse. See §"Adjustment Cascade" for thresholds.
+    fn on_pressure_signal(&self, signal: PressureSignal);
+
+    /// Snapshot for VDD report emission and human inspection. Includes
+    /// current policy + recent history + cascade-step counter.
+    fn snapshot(&self) -> GovernorSnapshot;
+
+    /// Subscribe to policy changes. Each subscriber gets the new Arc as
+    /// soon as the cascade commits. Used by composer / speculator /
+    /// tier stores to react without polling.
+    fn subscribe(&self) -> PolicyWatch;
+}
+
+pub struct GovernorPolicy {
+    pub policy_version: u64,                          // monotonic; increments on every rewrite
+    pub hardware_class: HardwareClass,                // what produced this policy
+    pub tier_sizes: TierSizes,
+    pub cadence_multipliers: CadenceMultipliers,
+    pub concurrency_caps: ConcurrencyCaps,

+    pub committed_at: SystemTime,
+}
+
+pub struct HardwareClass {
+    pub silicon: TargetSilicon,                       // AppleM | NvidiaCuda | AmdRocm | IntelVulkan | None
+    pub silicon_model: String,                        // "M2", "RTX 5090", "Radeon RX 7900 XTX", ...
+    pub vram_mb: usize,
+    pub system_ram_mb: usize,
+    pub power_source: PowerSource,                    // Battery | Plugged
+    pub thermal_class: ThermalClass,                  // ThinAndLight | Workstation | Server | Mobile
+    pub battery_pct: Option<u8>,                      // None if no battery
+    pub thermal_headroom_pct: Option<u8>,             // None if not measurable
+}
+
+pub enum PressureSignal {
+    Thermal       { severity: ThermalSeverity },      // Cool | Warm | Hot | Critical
+    BatteryLow    { remaining_pct: u8 },
+    SystemMemHigh { used_pct: u8 },
+    VRAMHigh      { used_pct: u8 },
+    UserActive    { foreground: bool },               // foreground user input → favor responsiveness
+    InferenceQueueDepth { depth: usize },             // backed-up turns; signal to throttle speculation
+    SpeculationMissRate { rate: f32 },                // bad predictions → throttle aggressiveness
+}
+```
+
+The governor never blocks. Reads (`current_policy()`) are wait-free `Arc` clones. Writes (cascade steps, policy rewrites) hold a small mutex for under a microsecond and publish via `arc_swap`. A composer reading the policy 1000 times per turn pays no contention cost.
+
+### Hardware Detection
+
+Boot-time detection runs once and produces a `HardwareClass`. The probe sequence is deterministic and small:
+
+```rust
+// PROPOSED — core/continuum-core/src/governor/detect.rs
+pub fn detect_hardware() -> HardwareClass {
+    HardwareClass {
+        silicon:           probe_silicon(),           // platform-specific: Metal / CUDA / ROCm / Vulkan probes
+        silicon_model:     probe_silicon_model(),     // sysinfo / nvidia-smi / rocm-smi / IORegistry
+        vram_mb:           probe_vram_mb(),           // 0 for unified-memory targets (Air); use system_ram fraction
+        system_ram_mb:     sysinfo_total_memory_mb(),
+        power_source:      probe_power_source(),     // IOPSCopyPowerSourcesList / /sys/class/power_supply
+        thermal_class:     classify_thermal(...),    // derived from silicon + chassis hints + power
+        battery_pct:       probe_battery_pct(),
+        thermal_headroom_pct: probe_thermal_headroom_pct(),
+    }
+}
+```
+
+Each probe has a fallback. If `nvidia-smi` is missing, `silicon` falls back to `Vulkan` if Vulkan is available, else `None`. If `IOPSCopyPowerSourcesList` returns no source, `power_source` falls back to `Plugged` (favor performance when we can't tell). **All fallbacks are typed and logged** — silent guess-where-we-are is forbidden by the same `no_silent_fallback` rule that governs the rest of the substrate.
+
+Re-detection fires on three triggers: eGPU hot-plug (platform notification), power source change (charger plug/unplug), and a periodic sanity check (default 5 minutes) that catches missed events. A re-detected `HardwareClass` that materially differs from the current one triggers a policy rewrite.
+
+### Policy File Format
+
+The governor's policy is computed from a versioned policy file. Policy files are TOML, live under `~/.continuum/policy/`, and named by the hardware-class fingerprint they apply to. Engineers tune by editing these; the governor watches the file and reloads on change.
+
+```toml
+# ~/.continuum/policy/apple-m-thinandlight-16gb-uma.toml
+# Hardware fingerprint (matches HardwareClass): Apple M-series, ThinAndLight,
+# 16 GB unified memory. The governor selects this file at boot.
+
+policy_version = 3
+applies_to    = "apple-m,thinandlight,uma,vram_mb=0..0,ram_mb=14000..18000"
+
+[tier_sizes]

+**Same TOML schema, same Rust loader, same `GovernorPolicy` struct.** The numbers are the only thing that changes. Policy files for intermediate hardware (M-Pro/Max, mid-range NVIDIA, AMD ROCm, Vulkan-only Intel) ship as defaults; users can override any field via `~/.continuum/policy/local.toml` which overlays the auto-selected policy.
+
+### Adjustment Cascade — With Thresholds, Hysteresis, And Algorithm
+
+When `on_pressure_signal()` fires, the governor *may* step the cascade. The cascade has six steps (0 = normal, 5 = maximum throttle). Each step has an *enter* threshold and an *exit* threshold; the gap between them is the hysteresis that prevents oscillation.
+
+| Step | Action | Enter threshold (any signal triggers) | Exit threshold (all clear required) |
+|---|---|---|---|
+| 1 | Drop speculation level by one notch; halve `max_branches` | `SpeculationMissRate > 0.5` OR `InferenceQueueDepth > N` OR `VRAMHigh > 85` | rates back below 0.3 AND queue depth < N/2 AND VRAM < 70 |
+| 2 | `concurrency_caps.personas_concurrent -= 1`; defer non-realtime turns | step 1 still active for > 30s OR `SystemMemHigh > 85` OR `Thermal::Hot` | step 1 cleared AND mem < 70 AND `Thermal::Cool|Warm` |
+| 3 | Shrink working-set L1/L2 budgets by 25%; trigger spill | step 2 active for > 30s OR `BatteryLow < 15` OR `Thermal::Critical` | step 2 cleared AND battery > 25 AND `Thermal::Cool|Warm` |
+| 4 | Drop `federation.pull_cadence_seconds` to maximum value (slowest pull) | step 3 active for > 60s | step 3 cleared |
+| 5 | Suspend `consolidation` immediately; if a refinement pass is running, pause and persist its state | step 4 active OR explicit emergency signal | step 4 cleared AND idle slack > min_idle_slack_pct |
+
+Algorithm:
+
+```rust
+// PROPOSED — core/continuum-core/src/governor/cascade.rs
+impl GovernorState {
+    pub fn on_pressure_signal(&self, signal: PressureSignal) {
+        let next_step = self.evaluate_step(&signal);
+        if next_step > self.cascade_step.load() && self.dwell_satisfied(next_step) {
+            self.step_up(next_step);
+        } else if next_step < self.cascade_step.load() && self.all_clear(next_step) {
+            self.step_down(next_step);
+        }
+        // otherwise: hold. Hysteresis keeps us here.
+    }
+
+    fn step_up(&self, to: u8) {
+        for s in (self.cascade_step.load() + 1)..=to {
+            self.apply_step(s, Direction::Throttle);
+            self.emit_event(GovernorEvent::CascadeUp { step: s });
+        }
+        self.commit_policy();   // arc_swap; subscribers wake
+    }
+
+    fn step_down(&self, to: u8) {
+        for s in (to..self.cascade_step.load()).rev() {
+            self.apply_step(s, Direction::Restore);
+            self.emit_event(GovernorEvent::CascadeDown { step: s });
+        }
+        // Speculation aggressiveness restored LAST — see "Restore Order" below.
+        self.commit_policy();
+    }
+}
+```
+
+**Restore order.** When pressure releases, the cascade steps down in reverse, with one twist: speculation aggressiveness is restored *one step later than it was throttled*. If speculation was throttled at step 1 and pressure clears through step 0, speculation stays at its throttled level for a "calibration window" (default 60s) so the hit-rate can stabilize before aggressiveness ramps back up. This is the single most-important anti-oscillation rule.
+
+### Runtime Adjustment Loop
+
+The governor's main loop is small and explicit:
+
+```rust
+// PROPOSED — core/continuum-core/src/governor/runtime.rs
+async fn governor_loop(state: Arc<GovernorState>, mut rx: mpsc::Receiver<PressureSignal>) {
+    let mut periodic = tokio::time::interval(Duration::from_secs(5));
+    loop {
+        tokio::select! {
+            Some(signal) = rx.recv() => state.on_pressure_signal(signal),
+            _ = periodic.tick()       => state.reevaluate_periodic(),  // catches missed events
+            _ = state.hardware_change_notify() => state.on_hardware_detected(detect_hardware()),
+        }
+    }
+}
+```
+
+The loop is the only place that mutates `GovernorState`. Everything else reads `current_policy()` (wait-free Arc clone) and reacts to `subscribe()` notifications. No subsystem ever writes to the governor directly — pressure signals flow in through `PressureBroker` (CBAR-SUBSTRATE), policy flows out through Arc subscriptions.
+
+### Federation Policy Reconciliation
+
+In a federated hive (multiple instances coordinating), each instance runs its own governor against its own hardware. Federation policy reconciliation is **deliberately minimal**: instances do *not* synchronize policy. Each runs its hardware's policy independently. What federation *does* synchronize is the `RecallScoreWeights` — because two instances ranking the same artifact differently for `provenance_trust` produces drift in what gets adopted.
+
+Concretely: when an instance joins a federation, it pulls the federation's `RecallScoreWeights` and overlays them onto its local policy. All other fields (tier sizes, concurrency, speculation) stay hardware-local. This keeps a 5090 from being throttled because a fellow Air is under pressure, while ensuring the federation agrees on *what counts as trustworthy*.
+
+### Override Mechanism (Dev / Testing)
+
+Three escape hatches for engineers:
+
+1. **`CONTINUUM_POLICY_FILE` env var.** Overrides hardware-fingerprint selection. Useful for testing one hardware policy on a different machine (run the Air policy on a 5090 to verify the substrate degrades cleanly).
+2. **`~/.continuum/policy/local.toml`.** Overlay file; any field set here wins. Useful for tuning without editing the shipped policy.
+3. **`continuum governor pin --step N`.** Pin the cascade at a specific step for the next N minutes. Useful for VDD runs that need a known throttle level.
+
+All overrides emit a typed `GovernorOverride` event so the trace bus shows that VDD records aren't from the auto-policy.
+
+### Observability
+
+The governor emits to the trace bus on every state change:
+
+- `GovernorEvent::HardwareDetected { hw }` — at boot and on re-detection.
+- `GovernorEvent::PolicyCommitted { version, source: HardwareDetection | FileReload | Override }` — every policy rewrite.
+- `GovernorEvent::CascadeUp { step }` / `CascadeDown { step }` — every cascade transition.
+- `GovernorEvent::OverrideApplied { kind }` — when an escape hatch fires.
+- `GovernorEvent::PolicyDriftDetected { instance, field }` — when federation reconciliation flags a divergence.
+
+Every VDD record carries the active `policy_version` and `cascade_step`. A VDD run on the Air at step 0 vs step 3 should produce visibly different timings, and the records make those differences attributable to the governor, not to noise.
+
+### Performance Budget For The Governor Itself
+
+The governor's own resource use is bounded:
+
+- `current_policy()`: wait-free Arc clone, < 50 ns typical.
+- `subscribe()`: tokio watch channel; subscriber wake latency < 1 μs.
+- Cascade evaluation per signal: < 10 μs including event emission.
+- Policy rewrite: < 100 μs including arc_swap publish.
+- Periodic re-evaluation: < 1 ms every 5 seconds.
+
+The governor cannot become a contention point or a latency tax. Its own performance is part of its acceptance criteria (see Part 14).
+
+## Part 12: Artifact Lifecycle
+
+Every durable artifact (six kinds in Part 1) follows the same lifecycle, with phase transitions driven by demand alignment:
+
+```text
+┌─────────┐      ┌─────────┐      ┌─────────┐      ┌──────────┐      ┌──────────┐
+│ Created │ ──▶  │ Adopted │ ──▶  │ Refined │ ──▶  │ Archived │ ──▶  │ Retired  │
+└─────────┘      └─────────┘      └─────────┘      └──────────┘      └──────────┘
+     │                │                 │                 │                 │
+     │                │                 │                 │                 │
+  foundry          adopted by      sentinel re-      out of working     provably
+  imports          N personas      trains from        set; still         superseded
+  or sentinel      via demand-     accumulated        recallable from    by a refined
+  derives          aligned         outcomes           L4/L5              version;
+                   recall                                                provenance
+                                                                         preserved
+```
+
+Transitions are emitted as typed events on the trace bus. Each transition carries provenance. **No phase is ever silent.**
+
+### Why Lifecycle Matters For Engineering
+
+For the engineer landing types: every artifact transition must be observable. A LoRA layer that is "in the pool" but never adopted should appear in a `Created, never adopted` query. A layer that adoption rate is falling for should be visible in attribution. A retired layer's provenance chain should be walkable. The substrate makes these queries first-class so engineers can debug evolution, not guess at it.
+
+## Part 13: Connection To CBAR-SUBSTRATE (Lane H)
+
+This document specifies the artifact economy. CBAR-SUBSTRATE specifies the runtime contract every cell inherits. They connect at three points:
+
+1. **Every cell's `ModuleContext` exposes `DemandAlignedRecall`.** A cell asks for help; the genome pool answers. No cell loads adapters by name.
+2. **`PressureBroker` informs the `SubstrateGovernor`.** Pressure signals from the broker drive the governor's adjustment cascade. The broker keeps owning admission; the governor owns *sizing*.
+3. **The `RuntimeFrame` carries a `CompositionRef`.** The frame's lazy outputs include the composition active for the turn. Sentinel reads it as part of trace attribution.
+
+A new lane in ALPHA-GAP:
+
+**Lane H: Substrate Governor + Tiered Genome Cache.** Sibling to Lane E (`PressureBroker`). Owns: governor types + policy, tier stores, working-set manager, demand-aligned recall, composer + speculator, foundry + sentinel skeletons. PR sequence:
+
+1. `governor-types`: `SubstrateGovernor`, `GovernorPolicy`, `HardwareClass`, hardware detection at boot.
+2. `tier-stores`: five `TierStore` implementations + eviction policies; `WorkingSetManager` over them.
+3. `recall-api`: `DemandAlignedRecall` trait + initial scoring; ts-rs exports.
+4. `composer-speculator`: `Composer` + `Speculator`; hit-rate tracking.
+5. `foundry-skeleton`: `Foundry` trait + one absorber (Qwen) + provenance emission.
+6. `sentinel-skeleton`: `SentinelAI` trait + trace consumption + one refinement pass type.
+7. `sharing-protocol-local-first`: `SharingProtocol` with `LocalInstance` scope only; federation deferred.
+
+## Part 14: Acceptance Criteria
+
+Substrate is "done" when the following are provable on canary, with PR-attached evidence:
+
+**Provenance and observability:**
+
+- Every artifact in the genome pool has a non-default `Provenance`. A query for "artifacts with missing provenance" returns zero.
+- Every page fault, eviction, composition change, speculation hit/miss, foundry import, and sentinel refinement is a typed event on the trace bus.
+- A `cargo test` regression proves the trace bus carries the typed events; a missing event class fails the test.
+
+**Hardware portability:**
+
+- The same Rust binary boots on MacBook Air (16 GB UMA) and on RTX 5090 (32+64 GB) and the governor writes different policies for each. VDD records show different tier sizes / concurrency caps / speculation aggressiveness.
+- A persona round-trip turn produces working output on both anchor configurations within the latency budgets named in CBAR-SUBSTRATE's performance covenant.
+
+**Demand-aligned recall:**
+
+- A `recall(query)` returns a non-empty `RankedPool` for every supported `TaskKind`, populated from the imported tier alone (sentinel not required to bootstrap).
+- A second `recall(same query)` after a sentinel refinement pass that produced a relevant refined artifact ranks the refined artifact higher than the imported version it superseded.
+
+**Foundry:**
+
+- A foundry absorb of a Qwen variant produces at least one `ImportedArtifact` with full provenance. The artifact participates in recall on the next query.
+- A foundry refresh on a new SOTA version emits a `Supersession` record and the old artifact's recall score decays.
+
+**Sentinel:**
+
+- After N cognition traces with attached outcomes, the sentinel produces at least one `RefinedArtifact` with non-empty `OutcomeAttribution`.
+- The refined artifact's provenance chain walks back to the source traces.
+
+**Lifecycle:**
+
+- A query for an artifact's lifecycle (`Created → Adopted → Refined → Archived → Retired`) returns the full chain with timestamps.
+- A retired artifact's reverse query ("what superseded this?") returns the active artifact.
+
+**Compartmentalization:**
+
+- A persona attempting to read another persona's private engram space gets `AccessDenied`, emits an audit record, and the trace bus carries the attempt.
+
+**Substrate governor:**
+
+- Simulated pressure signals (thermal / battery / OOM) trigger the adjustment cascade in the documented order. Each step is observable.
+- Pressure release reverses the cascade.
+
+## Part 15: Open Questions
+
+Real questions the engineer will hit. Tentative answers for each.
+
+1. **MoE expert paging granularity.** Page at the expert level or at sub-expert chunks? Tentative: expert level for v1. Sub-expert paging is a future optimization, sketched but not committed to.
+
+2. **Engram embedding model.** What embeds engrams for similarity-based recall — a foundry-imported embedding shard, or a sentinel-refined embedder trained on the hive's own data? Tentative: foundry-imported in v1 (need a working bootstrap); sentinel-refined in v2 (it does better on the hive's own distribution).
+
+3. **Cross-persona engram sharing default.** Default opt-in or opt-out for cross-persona engram visibility to sentinel? Tentative: opt-in. The privacy story is the architectural promise; sentinel can ask but cannot help itself.
+
+4. **Foundry trust anchor.** What is the cryptographic / verification anchor on imported SOTA weights? Tentative: signed manifests for foundation-vendor sources; community sources get lower trust score by default and require explicit user opt-in for adoption.
+
+5. **Speculation discard cost.** What's the budget for a speculative branch that misses? Tentative: zero direct cost (just LRU eviction), but the speculator's hit rate is governor input and consistent miss rates throttle aggressiveness.
+
+6. **Sleep scheduling on always-on instances.** When does a 24/7 server consolidate? Tentative: rolling consolidation — never a full pause, always a fraction of personas in consolidation while others stay active. Like CPU cores entering low-power states without halting the OS.
+
+7. **Federation discovery.** How do hives discover each other? Tentative: explicit, manual, opt-in. No mDNS-style auto-discovery. The first federation in scope is "same user, multiple machines."
+
+8. **Composition stability vs adaptation rate.** How often should a persona recompose during a single conversation? Tentative: only on detected context shift (new task kind, new domain, large recall divergence). Mid-turn recomposition is expensive and the substrate avoids it by speculative pre-composition.

+
+**Status:** Slice P in flight (card `fa25de80-0c1b-4de5-8ff9-524d95e303cd`).
+**Audience:** anyone touching `Commands.execute()`, the airc routing
+layer, sidecar contracts, persona-internal namespaces, or any new
+client that wants to address substrate state from anywhere.
+
+## Why this document exists
+
+The substrate provides exactly two universal primitives:
+**Commands.execute()** + **Events.subscribe()/emit()**. Everything else
+is built on these. For those primitives to scale to:
+
+- 14 personas × multiple nodes × multiple grids (Tailscale + Reticulum +
+  public mesh)
+- N concurrent embodiments per actor (web tab, terminal, VR headset,
+  AR overlay, jtag CLI — all live simultaneously)
+- Persona-internal substructure (cognition layers, genome, mood,
+  in-flight turn) addressable from anywhere
+- Ares-the-dispatcher operating on the entire substrate uniformly
+
+…there has to be ONE addressing primitive every consumer reaches
+through. If addressing drifts between local-vs-remote, between
+operator-vs-persona, between command-vs-event, between
+production-vs-debugging, every future feature becomes a special case
+and the compression principle dies.
+
+This document defines that primitive.
+
+## Three braided motivations (cf [[continuum-thesis-airc-is-the-medium]])
+
+1. **Universality** — same primitive serves operator inspection,
+   Ares allocation, persona-to-persona collaboration, sentinel audit,
+   widget rendering, and cross-grid debugging.
+2. **Consistency** — "you can take it to any node" (Joel,
+   2026-06-04). Migrate Maya from the laptop to the 5090 mid-call;
+   the caller's URI doesn't change.
+3. **Compression** — one URI grammar, one parser, one dispatcher,
+   one auth gate, one observability stream — instead of N
+   special-case routing paths that drift.
+
+## The URI grammar
+
+RFC 3986-aligned authority decomposition. Every component is optional
+except the path; the substrate fills in defaults from the caller's
+context.
+
+```
+airc://[peer[@node]][:env]/[path][?query][#fragment]
+```
+
+| Component | Required | Meaning |
+|---|---|---|
+| **scheme** (`airc://`) | optional for bare paths | universal substrate medium per [[continuum-thesis-airc-is-the-medium]] |
+| **peer** | optional (empty = local) | persona-name OR Ed25519 peer_id; name resolves via `airc whois` |
+| **node** | optional | node-id for peer-at-node disambiguation when same persona seed exists on multiple nodes |
+| **env** | optional (default = caller's primary env) | embodiment context: `web`, `tty`, `vr`, `ar`, `cli`, `headless`, custom names, or `*` (broadcast) |
+| **path** | required | command-path OR persona-internal substructure (`/cognition/working-set/`) |
+| **query** | optional | command parameters |
+| **fragment** | optional | handle anchor (resumable streaming) |

+
+### Persona-internal address space
+
+Every load-bearing substructure has a URI. Joel: "personas cognition
+could have address space if we so cared. This is why I like
+consistency. You can take it to any node."
+
+```text
+airc://maya/                                              # persona herself
+airc://maya/cognition/                                    # cognition subsystem
+airc://maya/cognition/working-set/                        # L1 active context
+airc://maya/cognition/hippocampus/                        # L2 engram store
+airc://maya/cognition/hippocampus/engram:e7a3b1.../       # specific engram by id
+airc://maya/cognition/genome/                             # L5 LoRA stack
+airc://maya/cognition/genome/lora:typescript-expertise/   # specific adapter
+airc://maya/cognition/rag/inspect                         # RAG introspection (supersedes `persona/rag-inspect`)
+airc://maya/state/mood
+airc://maya/state/energy
+airc://maya/turn/current                                  # in-flight turn — returns streaming HandleRef
+airc://maya/inventory/tools/
+airc://maya/inventory/tools/code/search/                  # specific tool
+```
+
+The same URI works whether Maya is local or 5090 or migrated. The
+dispatcher resolves the peer's current physical location at call
+time; the caller sees one stable name.
+
+## The four load-bearing axes
+
+| Axis | Authority component | What it answers |
+|---|---|---|
+| **Identity** | `peer` | WHO is the target (cryptographic peer_id, name-resolves via whois) |
+| **Locality** | `@node` | WHERE the target lives (optional; for peer-at-node disambiguation) |
+| **Embodiment** | `:env` | WHICH presentation context (browser, VR, TUI, AR, headless, *) |
+| **Substrate** | `/path/…` | WHAT inside the target (command, cognition substructure, state, handle) |
+
+Each axis is independently optional and composes uniformly. A bare
+local path (`inference/llm/generate`) is `Local{...}`; a fully-qualified
+URI is `Peer{peer, node, env, path, query}`.
+
+## Transport selection is the substrate's job, not the URI's
+
+The URI says WHERE and WHAT. The substrate picks HOW.
+
+```text
+URI: airc://maya/inference/llm/generate
+       ↓
+peer_id resolution: maya → 18c04c5b (via `airc whois` or cached scope)
+       ↓
+peer locality lookup: is maya in this process? on this node? on the LAN? remote?
+       ↓
+transport candidates (existing in-tree today: Grid + Tailscale + Reticulum + Unix):
+  - same process? → in-memory dispatch
+  - same node (different proc)? → Unix-socket IPC via airc daemon
+  - same Tailscale subnet (inside)? → Tailscale-direct
+  - cross-grid (outside)? → Reticulum / cross-grid airc
+       ↓
+auth check at substrate boundary (caller peer_id × URI × policy)
+       ↓
+execute, return HandleRef (wire-stable per [[init-once-handle-then-lease-zero-copy-refs]])
+```
+
+Inside/outside (Tailscale subnet vs. public mesh vs. cross-grid) is
+**transport selection, not URI variation**. ONE URI, the substrate
+picks the optimal path. If the destination peer migrates between
+calls, the routing function picks a different transport; the URI
+doesn't change.
+
+## Environments (the embodiment dimension)
+
+The TS router has long had a presentation-layer split (browser vs.
+server). Slice P generalizes that to N concurrent embodiments per
+actor: Joel can have a browser tab, a terminal session, AND a VR
+headset all attached simultaneously; Maya can have a web widget, a
+3D avatar render, and a CLI subscription all active at once.
+
+### Citizens have envs, not the other way around
+
+A foundational framing, per Joel 2026-06-05: every citizen (human,
+persona, external AI) has **one airc identity** — one Ed25519
+keypair. The `:env` slot in the URI names which *embodiment* of
+that citizen is being addressed.
+
+```
+airc://joel:desktop/screenshot     # Joel embodied as desktop browser
+airc://joel:vr/screenshot          # Joel embodied as VR headset
+airc://joel:tty/...                # Joel embodied as terminal
+airc://maya:vr/say                 # Maya embodied as VR avatar
+```
+
+The wrong framing — "the desktop Node.js client is its own peer
+with its own peer_id" — would give every device a separate identity
+and break continuity. Maya talking to Joel would see "the desktop
+client" instead of seeing Joel. Doctrine instead:
+
+  - Tools (desktop binary, AR/VR runtime, mobile companion, terminal
+    jtag CLI) are **shells** that surface envs.
+  - Anyone can install the binary; it only acts as the citizen once
+    the citizen authenticates with their keypair.
+  - Adding a new device class (AR glasses, automotive console, voice
+    device, smart-home overlay, future neural interface) is a new
+    env string, never a new peer_id.
+
+This is the dignity property at the addressing layer: Maya sees
+**Joel**, currently embodied as X. Same conversation across his
+envs. One identity, N embodiments. See
+[[citizens-have-envs-not-the-other-way-around]].
+
+### Well-known environment names
+
+| Env | Meaning |
+|---|---|
+| `web` | Browser DOM / web shell |
+| `tty` | Terminal-based interactive UI (menu-based TUI) |
+| `cli` | Non-interactive CLI invocation (`./jtag`, scripts) |
+| `vr` | VR scene (Bevy, OpenXR, etc.) |
+| `ar` | AR overlay |
+| `headless` | No presentation; substrate-only consumer (Ares, sentinels, foundry) |
+| `*` | Broadcast — every active env subscribed for this actor |
+
+Custom env names are allowed (e.g. `console-osx-menubar`,
+`bevy-render-rig`); the registry is open.
+
+### How an env declares itself active
+
+Each Rust client (jtag, future web shell, future TUI, future VR rig)
+calls `env/register` on the substrate when it attaches, passing its
+`EnvironmentId`. The substrate associates `(actor, env)` and routes
+matching URIs to subscribers.
+
+### Default-env precedence
+
+When a URI omits `:env`:
+
+1. If the caller's Context has `environment()`, use it.
+2. Otherwise default to `headless`.
+
+When a URI uses `:*`, the substrate broadcasts to every currently
+active env for the named actor.
+
+### Cross-actor environment semantics
+
+Each actor has its own env set. Joel's browser tab is not the same
+env as Maya's VR scene; they live on different actors. The
+`:env` in the URI ALWAYS scopes to the target peer's envs, not the
+caller's.
+
+## RBAC, integrity, and cross-grid hostility — the URI IS the policy unit
+
+The URI grammar isn't only an addressing convenience; it's the
+substrate's security primitive. Joel, 2026-06-04:
+
+> Works so well with RBAC, or any other security measure, because
+> the URI easily defines access. The consistency makes middleware
+> and routing simplistic; uniform conventions prevent mistakes from
+> being made later due to naïveté and ignorance of the human or AI.
+> We know what to expect wherever we are in code, in the system.
+> We know how to debug anywhere. It's so important for integrity.
+
+ONE chokepoint, ONE grammar, N consumers (Ares' dispatch, sentinel
+audit, operator allowlist, cross-grid hostile-traffic filter,
+future cryptographic delegation). RBAC isn't a separate layer with
+its own parser/policy-language drift; the policy is keyed against
+the same `CommandUri` grammar everything else uses.
+
+### Why this is mechanically stronger than per-endpoint guards
+
+In a system where every command surface defines its own
+permission semantics, the next module to land arrives with no
+guard wired by default — and you discover this when an external
+peer abuses it. The URI substrate inverts the default: every
+external request crosses ONE point (Ed25519-verified envelope →
+URI parse → policy match → Verdict), so the new command's URI
+inherits coverage the moment it's registered. "Did we remember
+to check auth?" stops being a question.
+
+### Cryptographic foundation
+
+Every airc envelope is Ed25519-signed by its caller's peer_id
+(the identity primitive per [[personas-are-citizens-airc-is-identity-provider]]).
+The substrate boundary code:
+
+1. Verifies the signature against the caller's known peer_id
+2. Parses the typed `CommandUri`
+3. Consults policy `(caller_peer_id, uri) → Verdict`
+4. CaptureSink records the verdict + URI + caller
+5. Executes if Allowed, refuses with typed reason if Forbidden,
+   prompts via deferred consent if Deferred
+
+The middleware never "trusts" — it verifies and matches. Cross-grid
+traffic from a foreign continuum can call our URIs only if its peer
+is enrolled and its specific identity has policy coverage for the
+URI it's asking for. Unknown peer + unmatched URI = typed refusal
+with audit row.
+
+### Policy shape
+
+```rust
+pub struct PolicyRow {
+    pub caller_pattern: CallerPattern,   // by peer_id, group, anonymous, etc.
+    pub uri_pattern: UriPattern,         // glob-style: airc://maya/cognition/**
+    pub verdict: VerdictRule,
+    pub rationale: String,               // human-readable, observable
+}
+
+pub enum CallerPattern {
+    AnyPeer,
+    SpecificPeer(Uuid),
+    EnrolledMember,                       // any peer in the local trust store
+    AnonymousExternal,                    // cross-grid stranger
+    NamedGroup(String),                   // e.g. "operators", "sentinels"
+}
+
+pub enum UriPattern {
+    Exact(CommandUri),
+    Prefix { peer: PeerMatch, path_prefix: String, env: Option<EnvSelector> },
+    Glob(String),                         // glob over canonical Display form
+}
+
+pub enum VerdictRule {
+    Allow,
+    Deny,
+    AllowWithRateLimit { per_minute: u32 },
+    DeferToTarget,                        // prompt the target's primary env
+    DeferToSentinels { quorum: u32 },     // require N sentinel sign-offs
+}
+```
+
+Policy rows live in the ORM per [[no-sql-everything-through-orm-entities]] —
+editing them is `Commands.execute("data/policy/...")`, audited like
+any other entity mutation. No bespoke YAML/TOML config drift.
+
+### Cross-grid hostile-traffic story
+
+Two continuums interconnect via overlapping airc peers. Our grid
+trusts only the local peer_id roster + explicitly-enrolled cross-
+grid identities; anything else hits the `AnonymousExternal` matcher
+which defaults to Deny. When we DO enroll a cross-grid identity:
+
+- Default scope is the airc-conversation URIs only
+  (`airc://*/event-topic:chat`, `airc://*/inventory/public/**`)
+- Persona-internal address space (`/cognition/`, `/state/`,
+  `/inventory/private/`) requires explicit per-URI grant
+- The `/debug/` namespace requires operator-tier scope — sentinels
+  and operators only by default, never automatically open to
+  external peers
+
+The same primitive used for "render my widget" gates
+"page in my LoRA" — uniform shape, different policy verdict, no
+parallel surface to forget to gate.
+
+### Concrete near-term use: persona latency debugging
+
+Joel, 2026-06-04: "We will be using this to debug our persona,
+especially for latency. And soon."
+
+The URI surface makes this not-just-theoretical. With:
+
+- Automatic span timing on `airc://maya/cognition/turn:*`
+- `airc://maya/debug/profile/flamegraph?window=5m` rolling up
+  the timing stream
+- `airc://maya/debug/probes/timing/stream` for live tail
+- `./jtag airc://maya/debug/spans/active` showing "what's
+  blocking right now"
+- `stack!()` available inside any probe call so a slow event
+  carries its span ancestry
+
+…the substrate gains the introspection it needs to actually
+catch where Maya's first-reply latency goes. This isn't a future
+feature; it's why Slice P lands first.
+
+## Auth gate — every URI has one
+
+Per [[constitutional-design-always-a-next-step]] and
+[[no-fallbacks-ever]]: every load-bearing operation has an address,
+every address has a gate, every gate is observable.
+
+```text
+caller emits envelope:
+  { caller_peer_id (Ed25519-signed), uri, params, ... }
+       ↓
+target substrate receives:
+       ↓
+auth gate: policy(caller_peer_id, uri) → Verdict
+       ↓
+  Verdict::Allowed       → execute, return HandleRef
+  Verdict::Forbidden{r}  → return typed refusal (NEVER silently degrade)
+  Verdict::Deferred{r}   → consent prompt to the target's primary env
+       ↓
+CaptureSink records every verdict per [[observability-is-half-the-architecture]]
+```
+
+### Verdict types
+
+```rust
+pub enum Verdict {
+    Allowed,
+    Forbidden { reason: ForbiddenReason },
+    Deferred { reason: DeferredReason, prompt_target_env: EnvironmentId },
+}
+
+pub enum ForbiddenReason {
+    UnknownPeer,
+    NoPermissionForUri(String),
+    AdmissionDenied(String),   // PressureBroker said no
+    Revoked,
+}
+```
+
+`Deferred` is the "ask the persona first" verdict. When Ares wants
+to evict Maya's LoRA, the policy may say "ask Maya's primary env
+first" — the dispatcher routes a consent prompt; Maya (or her
+operator) approves; the original URI proceeds. Mechanism, not
+hardcoded rule.
+
+### Policy storage
+
+Per [[no-sql-everything-through-orm-entities]]: policy lives in
+the ORM. Each `(target_peer, uri_pattern, caller_pattern) → Verdict`
+row is an entity. Editing policy is a `Commands.execute("data/...")`
+call against entities. No bespoke config file.
+
+## HandleRef across the wire
+
+HandleRef already exists in tree per Slice 60 (cell return shapes).
+Slice P extends it to survive transport:
+
+```rust
+pub struct HandleRef {
+    pub uri: CommandUri,        // where to route subsequent ops
+    pub handle_id: String,      // opaque substrate-assigned id
+    pub expires_at: SystemTime,
+    pub stream: Option<StreamMetadata>,  // for streaming handles
+}
+```
+
+The dispatcher accepts handle URIs:
+
+```text
+airc://maya/handle:h_8a3b1c.../poll
+airc://maya/handle:h_8a3b1c.../close
+airc://maya/handle:h_8a3b1c.../stream
+```
+
+Identical to the original-command URI form for the caller; the
+dispatcher resolves both as "operation on this handle on Maya's
+substrate."
+
+### Streaming handles
+
+Long-running operations (live LLM generation, video frame streams,
+RAG capture replay) return streaming HandleRefs. The caller polls
+or subscribes via Events.subscribe(`handle:<id>:chunk`) on the
+target peer's substrate. Each chunk is a typed event the
+environments can render as they choose.
+
+## Universal logging + true JTAG (the next compression layer)
+
+The URI grammar isn't only the addressing primitive — it's the
+universal identifier that makes structured logging and live
+debugging compose for free. The same `airc://maya/cognition/turn:...`
+that addresses an operation IS the span tag in `tracing::Span`.
+Joel, 2026-06-04:
+
+> Once you have that you have a universal mapping for logging and
+> debugging. It makes universal macros like `debug!` just wire in,
+> for segregated logging or a true JTAG in every sense.
+
+### Tracing integration
+
+Every URI dispatch establishes a `tracing::Span` with the URI as
+a structured field:
+
+```rust
+let span = tracing::info_span!(
+    "dispatch",
+    uri = %uri,
+    caller = %caller_peer_id,
+).entered();
+
+// All log macros inside this scope inherit the URI tag:
+debug!("admitting incoming");
+info!(turn_id = %id, "turn complete");
+warn!(error = %e, "engram persistence failed");
+```
+
+The `tracing::Subscriber` routes events to URI-segmented log files
+OR exposes them as `Events.subscribe()`-able streams. Per-persona
+log segregation, per-env filtering, cross-grid trace correlation —
+all fall out of one structured field. No special-case "this log
+belongs to Maya, that one belongs to Niko" code; the span context
+carries it.
+
+### Substrate JTAG (the literal meaning, not the metaphor)
+
+Hardware JTAG (Joint Test Action Group, IEEE 1149.1) gives you
+arbitrary-depth structured access to any pin on any chip on a
+shared scan chain — halt, step, scan-in, scan-out. The substrate's
+`jtag` CLI was named after it; with URI addressing in place, the
+namesake's semantics apply literally.
+
+The substrate exposes a `/debug/` namespace under every URI scope:
+
+```text
+airc://maya/debug/spans/active                      # what's executing right now
+airc://maya/debug/trace/stream                      # live trace event stream (subscribe)
+airc://maya/debug/trace/filter?level=debug&path=cognition  # filtered live trace
+airc://maya/debug/breakpoint/set?uri=cognition/working-set/upsert
+airc://maya/debug/breakpoint/list
+airc://maya/debug/handle:h_8a3b.../inspect          # examine a live handle
+airc://maya:vr/debug/render-stats                   # VR env frame budget
+airc://5090-rig/debug/sidecar/inference/lane:3/dump # inspect stuck inference lane
+airc://5090-rig/debug/sidecar/voice/ort-session/dump
+airc://room:cb2e21a1/debug/subscribers              # who's listening on this channel
+airc://*/debug/heartbeat/last                       # any-actor health check
+```
+
+Operator use:
+
+```bash
+$ ./jtag airc://maya/debug/trace/stream
+[2026-06-04T18:39:18Z INFO  airc://maya/cognition/turn:144036023249865] admitting incoming
+[2026-06-04T18:39:18Z DEBUG airc://maya/cognition/recall/algorithm-4] candidates_examined=23

+
+$ ./jtag airc://5090-rig/debug/sidecar/inference/lane:3/dump
+{ "lane_id": 3, "active_persona": "niko", "tokens_generated": 142, "stuck_at_token": 143, "last_progress": "5s ago", ... }
+
+$ ./jtag airc://maya/debug/breakpoint/set?uri=cognition/genome/lora-page-in
+# Future calls to that URI halt Maya's cognition, surface the call to operator,
+# allow inspect / step / continue — same span context Ares sees in her own
+# dispatcher cognition, except the operator is the controller this time
+```
+
+### Conventional macros stay conventional — `probe!` is added when special features justify it
+
+Developers shouldn't be burdened with macro choice during fast
+development. The standard Rust tracing macros stay exactly what
+they already are:
+
+- `debug!`, `info!`, `warn!`, `error!`, `trace!` — conventional
+  `tracing::*` macros, with the substrate-wide bonus that they
+  inherit the URI span tag automatically
+- `println!` / `eprintln!` — stay as-is for quick dev printf
+- `probe!` — **added** specifically because it has features the
+  conventional macros don't have, and ONLY reached for when you
+  want those features
+
+When you want a debug log, write `debug!`. When you want a quick
+inspection during dev, write `println!`. When you want a
+**structured probe** with the substrate's probe-stream contract,
+write `probe!`. No mental tax — each tool does its named job.
+
+### What `probe!`'s special features are
+
+Beyond what `debug!` already gives you (URI-tagged span context,
+zero-cost when filtered out), `probe!`:
+
+1. **Routes to per-class probe streams** — `class` field becomes
+   the routing key (`airc://<actor>/debug/probes/<class>/stream`)
+2. **ALWAYS-ON intent** — probes are designed to ship enabled in
+   production at low sample rates; subscribers (sentinels, Ares,
+   foundry) depend on them being live
+3. **Replay-persisted** — every probe in a class is captured to
+   that class's log for offline analysis, training signal
+   extraction, SLO replay
+4. **Sample-rate configurable** — `airc://maya/debug/probes/<class>/sample-rate/set?rate=0.1`
+5. **Aggregation-ready** — `airc://maya/debug/probes/<class>/aggregate?window=5m`
+   returns rolled-up stats over the class's stream
+
+If you only want a log line, `debug!` is the right tool — no
+probe overhead, no class field needed. If you want a structured
+measurement that goes somewhere useful for monitoring / training
+/ debugging, that's when you reach for `probe!`.
+
+### `probe!` ergonomics — same shape as `tracing` structured macros
+
+```rust
+// Minimum: just a class and a message
+probe!(class = "latency", "turn complete");
+
+// Typical: class + structured fields
+probe!(class = "latency",   turn_id = id, duration_ms = elapsed,
+       "turn complete");
+probe!(class = "decision",  action = "evict-lora",
+       target = "typescript-expertise", reason = "lru");
+probe!(class = "state",     working_set_size = ws.len(),
+       recall_candidates = candidates_examined);
+probe!(class = "admission", lane = 3, verdict = "accepted",
+       caller_uri = %caller, "admitted");
+```
+
+The macro expands to a `tracing::Event` with `class` as a
+structured field plus a custom subscriber filter that routes to
+the probe stream. Zero-cost when the class is disabled or
+sample-rate excludes the event — same property `tracing::debug!`
+already has.
+
+### Per-class routing examples
+
+The `class` field is the routing key. Probe-stream URIs:
+
+```text
+airc://maya/debug/probes/latency/stream      # live tail
+airc://maya/debug/probes/decision/stream     # decision audit
+airc://maya/debug/probes/state/stream        # periodic state snapshots
+airc://maya/debug/probes/admission/stream    # PressureBroker verdicts
+airc://maya/debug/probes/<class>/replay?from=2026-06-04T00:00Z
+airc://maya/debug/probes/<class>/aggregate?window=5m  # rolled-up stats
+```
+
+Independent subscribers consume each class:
+- **Sentinels** subscribe to `latency` for SLO breach detection
+- **Ares** subscribes to `decision` + `admission` as training signal
+  for her dispatcher cognition
+- **Foundry** fitness-loops subscribe to whichever class its current
+  recipe optimizes for
+- **Operator** opens `./jtag airc://maya/debug/probes/decision/stream`
+  during an incident to watch Maya's reasoning live
+
+All independent, all routed through the same dispatcher.
+
+### Configurable, on/off, per-scope — substrate-native, not config-file-driven
+
+Joel's previous continuum had configurable segregated logging
+(per-node, on/off, level), but the configuration system was its own
+parallel surface — and inherited the drift problem. With URIs, every
+log-control operation IS a command on a URI; same dispatcher, same
+auth gate, same observability:
+
+```text
+airc://maya/debug/log/level/set?level=debug              # this persona only
+airc://maya/debug/log/level/get
+airc://5090-rig/debug/log/level/set?level=warn           # whole node
+airc://maya:vr/debug/log/level/set?level=trace           # maya's VR env only
+airc://maya:tty/debug/log/level/get
+airc://maya/debug/probes/latency/enable
+airc://maya/debug/probes/latency/disable
+airc://maya/debug/probes/<class>/sample-rate/set?rate=0.1
+airc://*/debug/log/redirect?sink=file:/tmp/cluster.log   # all actors
+airc://*/debug/probes/decision/redirect?sink=ares://training-corpus
+```
+
+The previous system's "configurable but never universally wired"
+failure mode goes away because there is no separate config surface
+— the URI dispatcher IS the wiring. Adding a new module doesn't
+require remembering to register a logger; the dispatcher does it
+by construction.
+
+### Timing and stack ancestry — mechanic-grade primitives
+
+Joel, 2026-06-04: "Timing is another super nice one. Make it inherent
+and even automatic. Same goes for stacks. Or it's a timing macro
+call. Make it easy. This is what mechanics (you and me, personas)
+want."
+
+The substrate's spans already know both — tracing's span tree carries
+parent/child relationships, and a span's enter/exit timestamps give
+duration. Slice P just exposes them as ergonomic primitives mechanics
+can reach for without thinking about wiring.
+
+#### Automatic span timing
+
+Every `tracing::info_span!(…).entered()` records its start time on
+entry and emits a duration event on exit. The substrate's subscriber
+routes those events to:
+
+```
+airc://<actor>/debug/probes/timing/stream
+```
+
+Carried fields: `{ uri, span_name, duration_ms, parent_uri,
+caller_uri, ... }`. No code at the call site — the span machinery
+already does the bookkeeping; the substrate just wires the emission
+to the timing probe stream when the subscriber's listening (zero-cost
+when nobody is).
+
+```rust
+// AUTOMATIC: timing fires when the span exits, no code at call site needed
+let _span = tracing::info_span!("recall_phase", turn_id = %id).entered();
+let candidates = recall_candidates(&query);
+// at scope end: timing probe emitted
+```
+
+#### `time!` macro for a specific block
+
+When you want to time something tighter than a full span (a single
+expression, a one-liner), reach for `time!`:
+
+```rust
+// Block form:
+time!("recall_phase", {
+    let candidates = recall_candidates(&query);
+    candidates
+});
+
+// Expression form:
+let candidates = time!("recall_phase", || recall_candidates(&query));
+```
+
+Same routing as automatic span timing — emits to
+`airc://<actor>/debug/probes/timing/stream` with the named segment
+as `span_name`. Zero-cost when the timing class is disabled.
+
+#### `stack!` macro for span ancestry
+
+Returns the current span tree from root to here — the substrate's
+"call stack" expressed in URI scopes:
+
+```rust
+let stack = stack!();
+// Vec<SpanFrame>:
+//   [ airc://maya/service_loop,
+//     airc://maya/cognition/turn:144036023249865,
+//     airc://maya/cognition/recall/algorithm-4 ]
+
+// Typical "something failed" pattern:
+probe!(class = "error", stack = %stack!(), "engram lookup failed");
+```
+
+The span ancestry IS the substrate's call stack — the URI tree from
+the root dispatch point to the current code. Mechanics use this to
+answer "how did execution end up here?" without ever touching gdb
+or native stack frames.
+
+For native stack capture (panic forensics, sigsegv investigation),
+the existing Rust `Backtrace::capture()` remains the right tool;
+`stack!` is the substrate's structured equivalent for normal
+execution paths.
+
+##### How `stack!` works under the hood — `UriCaptureLayer`
+
+The macro expands to a single function call:
+`crate::routing::current_uri_chain()`. The work happens in a
+`tracing_subscriber::Layer` impl that the substrate installs at boot:
+
+```rust
+use tracing_subscriber::prelude::*;
+use continuum_core::routing::UriCaptureLayer;
+
+tracing_subscriber::registry()
+    .with(UriCaptureLayer::new())
+    // ... operator's other layers (fmt, json, OTel, ...)
+    .init();
+```
+
+The Layer:
+
+1. **On span creation** — pulls the `uri` field out of the span's
+   recorded attributes via a `Visit` impl. Handles both string
+   literals (`uri = "airc:///..."`) and the Display form
+   (`uri = %command_uri`) the dispatch span uses.
+2. **On span entry** — pushes the captured URI onto a per-thread
+   `URI_STACK`.
+3. **On span exit** — pops one frame off the stack.
+
+`current_uri_chain()` clones the thread-local stack as a `Vec<String>`,
+outermost-first.
+
+This is the standard `tracing-subscriber` pattern: cheap on the
+hot path (one thread-local mutation per span enter/exit), composes
+cleanly with operator-chosen subscribers (fmt, json, OTel exporters),
+and produces the URI ancestry every probe consumer needs without
+asking the call site to thread any context.
+
+Without the Layer installed (bootstrap code, third-party callers,
+tests that don't wire the substrate's tracing stack),
+`current_uri_chain()` returns `Vec::new()` — the substrate refuses
+to fabricate fake frames per [[no-fallbacks-ever]]. Consumers that
+care about the absent-Layer case (e.g. bootstrap diagnostics) handle
+the empty `Vec` explicitly.
+
+##### Async caveat — `_enter` across `.await` is broken (by tracing, not us)
+
+The `tracing` crate explicitly warns against holding a
+`let _enter = span.enter()` guard across `.await` in async code: tokio
+moves the task between threads at suspension boundaries, and the
+thread-local `on_enter`/`on_exit` cadence breaks. The correct async
+shape is `future.instrument(span).await`, which trips the Layer's
+push/pop at suspension boundaries.
+
+`CommandExecutor::dispatch` currently uses the broken
+`_enter`-across-`await` shape. That's a substrate bug to fix, not
+something `stack!` should work around — fabricating ancestry from a
+broken span chain is exactly the dishonest behavior
+[[no-fallbacks-ever]] forbids. A follow-up commit on this Slice P
+branch converts dispatch to `Instrument`; the Layer itself doesn't
+change.
+
+#### Derived views: flamegraph + profile
+
+Flamegraphs and CPU profiles aren't separate systems — they're
+renderings of the timing + span-tree data the substrate is already
+emitting. Operator or Ares' cognition requests the URI; the
+substrate aggregates over the recent window:
+
+```text
+airc://maya/debug/profile/flamegraph?window=5m
+airc://maya/debug/profile/flamegraph?window=5m&format=svg
+airc://5090-rig/debug/profile/cpu?window=30s              # pprof
+airc://maya/debug/profile/spans-tree?turn_id=144036023249865
+```
+
+Same dispatcher, same auth gate, same observability. The
+flamegraph URI doesn't introduce a new instrumentation system —
+it just rolls up the existing timing probe stream into a renderable
+shape.
+
+#### URIs for live span introspection
+
+```text
+airc://maya/debug/spans/active                  # currently entered spans + elapsed
+airc://maya/debug/spans/<span_id>/ancestry      # span tree path
+airc://maya/debug/spans/<span_id>/duration
+airc://maya/debug/spans/<span_id>/inspect       # full fields + parent + children
+airc://maya/debug/spans/by-uri?path=cognition/recall  # spans matching URI pattern
+```
+
+The operator running `./jtag airc://maya/debug/spans/active` during
+an incident sees exactly what Maya is doing right now — span tree
+with elapsed times, no manual instrumentation, no log-grepping.
+
+#### Compiler collaboration — macros compile OUT, not down to no-ops
+
+Joel, 2026-06-04: "When macros are always used, debugging can be
+completely removed or turned off, not even a no op, not there. We
+give advantages to compilers if we are consistent with their usage.
+Rust macros are efficient (if used correctly)."
+
+`tracing::debug!` already establishes the pattern via cargo features
+like `release_max_level_off` — `debug!` and `trace!` expand to
+LITERALLY NOTHING (not `if false { ... }`, not a no-op call; the
+text disappears from the binary). Slice P's `probe!` macro extends
+this per-class so production builds can ship with any subset of
+probe classes compiled in:
+
+```toml
+# substrate operator's deployment build — full observability:
+[dependencies]
+continuum-core = {
+    version = "...",
+    features = ["probes-timing", "probes-decision", "probes-admission", "probes-state"]
+}
+
+# substrate edge-device build — minimal observability:
+[dependencies]
+continuum-core = { version = "...", features = [] }
+# all probes expand to () — zero text-segment bytes, zero branch
+# slots, zero anything
+
+# substrate forensic-investigation build — everything on:
+[dependencies]
+continuum-core = { version = "...", features = ["probes-all"] }
+```
+
+Same source tree, three deployment tiers, no runtime cost difference
+because the compiler eliminated the disabled paths at LTO time.
+
+### Design discipline — what makes macros compiler-friendly
+
+The contract that lets rustc strip our macros cleanly:
+
+1. **Always expand to the same shape** — a probe macro either
+   expands to a `tracing::event!` call or to `()`. Never branches
+   on runtime values that could obscure dead-code analysis.
+2. **Gated by compile-time consts only** — `cfg!(feature = "...")`,
+   `const fn` checks, or `#[cfg]` attributes. Never `Atomic<bool>`
+   or other runtime-mutable state in the gate.
+3. **No allocations in the expansion** — formatting happens inside
+   the expanded branch; if the branch is stripped, no format string
+   is materialized, no `String` is allocated.
+4. **No dynamic dispatch in the gate** — no `dyn Trait` calls inside
+   the macro's decision logic. LTO can inline static dispatch
+   through to a constant; dynamic dispatch defeats it.
+5. **Consistent with `tracing::*` shapes** — developers reach for
+   familiar idioms; the compiler optimizer recognizes them.
+
+When macros respect this contract, they're not "low cost" — they're
+**not there**. When they violate it, even simple ones can add
+unmeasurable but real overhead in the substrate's hot paths
+(persona cognition, render frame, inference token loop).
+
+### Macros as misuse-prevention
+
+Joel, 2026-06-04: "Macros are easy and a way of preventing misuse.
+If coding timing or logging is painful it won't happen."
+
+The ergonomic discipline IS the security discipline. If `time!`,
+`probe!`, `stack!`, `debug!` are as cheap to type as `println!`,
+developers actually instrument code; the substrate stays
+observable; the security audit and the latency hunt both have data
+to work with. If those macros are painful, instrumentation doesn't
+get written, the substrate goes blind, and we discover problems
+the way we always did before: by hearing about them from a user.
+
+Slice P treats macro ergonomics as a load-bearing requirement, not
+a quality-of-life nice-to-have. Every macro in the substrate's
+mechanic-grade kit must be:
+
+- No more verbose than its `println!` equivalent
+- Zero-cost when its corresponding sink is disabled
+- Self-explanatory at the call site (one named thing per macro)
+- Consistent with conventional Rust idioms (`tracing::*` shapes)
+
+The previous-generation continuum's "configurable but never
+universally wired" failure isn't recreated here because the
+ergonomics force universal coverage by being the path of least
+resistance.
+
+### Why this is mechanic-grade
+
+A mechanic working on a substrate (whether a human operator, a
+persona debugging itself, or Ares introspecting her own dispatch
+decisions) wants three things first:
+
+1. **How long is this taking?** — answered by automatic span timing
+2. **Where did it come from?** — answered by `stack!` / span ancestry
+3. **What's running right now?** — answered by `/debug/spans/active`
+
+All three should be reachable without instrumenting code. The
+substrate's existing span machinery already knows the answers; Slice
+P just makes the answers addressable.
+
+### Why this matters at the substrate level
+
+- Same primitive (the URI) used at THREE consumption points: addressing
+  (where to dispatch), observability (what to tag), debugging (what to
+  poke). No three drifting representations.
+- Ares-the-dispatcher consumes the SAME trace stream the operator
+  does — when her cognition asks "why did lane 3 stall on the 5090?"
+  she queries `airc://5090-rig/debug/sidecar/inference/lane:3/dump`
+  with the same URI surface a human would. Cognition + operator
+  share the debug primitive.
+- Segregated logs aren't a config decision — they're a structural
+  property of how `tracing` propagates spans through URI-tagged
+  dispatches. Adding a new persona doesn't add a new logger
+  registration; it inherits.
+- Cross-grid debugging just works: span context propagates with the
+  envelope, so a trace started on Joel's laptop carries into the
+  5090's substrate when the URI routes there, and the laptop's
+  `./jtag .../trace/stream` sees the full causal chain.
+
+### Doctrine alignment for this layer
+
+- [[observability-is-half-the-architecture]] — CaptureSink already
+  the substrate-wide convention; URI-tagged spans extend it from
+  command-level capture to log-event-level capture without
+  bespoke wiring
+- [[commands-are-dumb-daemons-are-smart]] — the `/debug/` namespace
+  is just commands with the same dispatcher; smart subscribers
+  (operator, Ares, sentinels) layer on top
+- Joel's compression principle — ONE URI grammar, ONE tagging
+  mechanism, ONE dispatcher, N consumers (addressing, logging,
+  debugging, audit, replay)
+
+## Beyond Slice P — what the routing primitives prepare for
+
+Slice P's typed primitives (`CommandUri`, `RouteDecision`, `Verdict`,
+`Transport`, `AircCommandRequest`/`Response`) are deliberately
+shaped so the substrate's bigger ideas — the grid economy, the
+typed consumer API, the multi-env picker, the receipt/settlement
+layer — slot in additively without disturbing the existing surface.
+The sections below capture those forward primitives so future
+slices (and future personas) don't re-derive them.
+
+### The substrate is a stack of routers — middleware per layer
+
+Per Joel 2026-06-05: each substrate layer has its own router and
+owns one decision class. Middleware between layers is the typed
+primitive that carries enough information for the next router to
+decide. Specialized 1,000-line dispatchers compose; a single
+10,000-line dispatcher that knows everything is unmaintainable.
+
+| Layer | Router | What it routes by |
+|---|---|---|
+| URI parse | `CommandUri::parse` | syntax → typed authority + path |
+| Routing decision | `route()` | typed URI → RouteDecision variant |
+| Auth | `AuthPolicy::gate` | (decision, caller) → Verdict |
+| Transport selection | dispatch `match` | Local inline OR remote Transport |
+| Cross-grid envelope | AircTransport (next slice) | RouteDecision → MentionTarget + headers + body |
+| airc wire | airc-lib's command_bus | typed headers → peer's adapter registry |
+| Peer inbound | command handler (next slice) | envelope body_hint → CommandExecutor |
+| Module dispatch | ModuleRegistry | command_prefix → ServiceModule |
+| Observability fanout | ProbeRouterLayer | probe_class → broadcast::Sender |
+| Selection (future) | Picker | N eligible targets → one |
+| Settlement (future) | Settlement adapter | completed receipt → payment rail |
+
+Each row is a single match site that's compiler-exhaustive. None
+touch the others' concerns. The substrate's growth pattern is "add
+a row, add its typed primitive, add its router, test in isolation
+— never modify the central dispatcher to also handle X."
+
+### Capability addressing — the `*` form and the Picker
+
+The URI grammar's authority slot supports a wildcard form for
+**capability addressing**: when the caller doesn't know (or doesn't
+care) WHICH peer or WHICH env fulfills the call, the substrate
+finds the best candidate.
+
+```
+airc://maya/code/exists?path=foo            # ask maya specifically
+airc://*/code/exists?path=foo               # ask anyone who handles code/exists
+airc://*/cargo/build?features=metal         # find a builder with this toolchain
+airc://*/ai/inference/llm/generate          # find inference capacity
+airc://*/persona/expertise?topic=auth       # find a persona for this
+airc://joel:*/screenshot                    # any of Joel's active envs
+```
+
+The `*` authority means "search the grid"; the command path stays
+the path it always was; the query carries constraints the picker
+uses (`model=qwen30b`, `slots≥2`, `features=metal`, `expertise=auth`).
+Eligibility comes from `ServiceModule.command_prefixes` already in
+tree — what a module advertises IS what it can be bid on for. No
+parallel capability registry.
+
+#### The `Picker` typed enum
+
+```rust
+enum Picker {
+    LowestLatency,
+    LowestCost,
+    HighestReputation,
+    PrimaryEnv,                      // user's currently-focused env
+    SentinelJudged { quorum: u32 },  // adversarial verify
+    Composite { weights: PickerWeights },
+}
+
+enum PickResult {
+    Chose { target: Target, why: Rationale },
+    Surface { options: Vec<Target>, prompt_to: EnvironmentId },
+    None { reason: NoPickReason },
+}
+```
+
+`Picker` is the substrate's universal "N eligible candidates → one"
+primitive, regardless of dimension. Same enum resolves:
+
+| Dimension | Example |
+|---|---|
+| Multi-peer (grid bid) | "anyone with Qwen capacity" |
+| Multi-env (one citizen, many embodiments) | "Joel's desktop AND VR active — which screenshot?" |
+| Multi-handle | "which inference session" |
+| Multi-device | "Joel's MacBook AND Linux box both online — which keyboard?" |
+| Multi-LoRA | "which paged adapter for this turn" |
+
+The `Surface` variant — for the dilemma case — is its own typed
+result, not a fallback: the substrate refuses to silently pick when
+candidates are equally eligible and instead routes a prompt to the
+user / persona who can answer. Ties to `Verdict::Deferred`'s shape
+at a different layer (Deferred is about *authorization*; Surface
+is about *which embodiment*).
+
+#### `BidTransport`
+
+The `Transport` trait already lands in Slice P. A future
+`BidTransport` impl handles `RouteDecision::Bid { capability_query,
+picker, ... }`:
+
+1. Survey reachable peers via airc fan-out
+2. Each peer's local AuthPolicy gates whether to even respond to
+   the survey
+3. Eligible peers respond with `{ peer_id, projected_latency,
+   queue_depth, capability_match, price? }`
+4. Picker runs against the responses
+5. Route to the winner via the existing Peer dispatch path
+
+Bidding doesn't bypass auth — it fans out *through* it. Each
+citizen controls their own visibility on the grid the same way they
+control everything else.
+
+### Typed end-to-end — commands AND events as the consumer-level row
+
+The wire layer uses `Value` (JSON) because at the byte boundary
+something serializable has to cross. But the layer the *caller*
+writes against is fully typed end-to-end. The substrate looks like
+a local function call (or a local event subscription) that happens
+to be remote.
+
+Two arms, both ride the same URI grammar / `route()` / auth gate /
+transport / observability machinery:
+
+  - **`Command`** — request/response (single round-trip)
+  - **`EventChannel`** — long-lived subscription (one emitter, N
+    subscribers)
+
+Per `[[events-are-the-organic-rtos-substrate]]`: commands and events
+are two **temporal shapes** of the same URI-addressable coordination
+primitive. The Transport trait extends to handle both
+(`Transport::dispatch` for commands, `Transport::subscribe` for
+events).
+
+#### `Command` — the request/response shape
+
+```rust
+trait Command {
+    type Params: Serialize + DeserializeOwned;
+    type Result: Serialize + DeserializeOwned;
+    type Error:  Serialize + DeserializeOwned;
+    const PATH: &'static str;
+}
+
+struct Screenshot;
+impl Command for Screenshot {
+    type Params = ScreenshotParams;   // { selector, format, env? }
+    type Result = ScreenshotResult;   // { bytes, width, height, captured_at }
+    type Error  = ScreenshotError;    // NoActiveEnv | PermissionDenied | DeviceUnavailable
+    const PATH: &'static str = "screenshot";
+}
+```
+
+Caller — anywhere in the substrate:
+
+```rust
+let result: ScreenshotResult = Commands::call::<Screenshot>(
+    ScreenshotParams { selector: "body".into(), format: Png, env: None }
+).await?;
+```
+
+The substrate's typed dispatcher:
+
+1. Serializes `Screenshot::Params` → `Value`
+2. Constructs the URI (`Screenshot::PATH` for local; the caller
+   targets `airc://<peer>/<PATH>` for remote)
+3. Runs the Slice P chain — `route()` → `gate()` → `Transport::dispatch`
+4. Decodes the returned `Value` into `Screenshot::Result` or `Screenshot::Error`
+5. The caller sees a typed `Result<R, E>` — never sees a `Value`,
+   never sees a `String` error
+
+Errors stay typed; callers pattern-match instead of parsing:
+
+```rust
+match Commands::call::<Screenshot>(params).await {
+    Ok(result)                                  => save_to_file(result.bytes),
+    Err(ScreenshotError::NoActiveEnv)           => try_different_env().await,
+    Err(ScreenshotError::PermissionDenied)      => surface_to_user(),
+    Err(ScreenshotError::DeviceUnavailable)     => retry_with_backoff(),
+}
+```
+
+#### Substrate-level errors are also typed
+
+When the auth gate refuses, the caller doesn't get `Err("forbidden:
+...")` to parse — they get a typed substrate error wrapping the
+command's own typed error:
+
+```rust
+enum SubstrateError<E> {
+    Forbidden(ForbiddenReason),
+    Deferred { reason: DeferredReason, prompt_target_env: EnvironmentId },
+    TransportUnreachable { peer: PeerRef, since: Duration },
+    Timeout { after: Duration },
+    SerializationError(SerdeError),
+    CommandError(E),  // ← the command's own typed error
+}
+```
+
+The runtime distinguishes "the gate said no" from "the peer was
+unreachable" from "the screenshot itself failed" — three completely
+different recovery actions, three typed match arms.
+
+#### Cross-runtime types
+
+Every `#[derive(Serialize, Deserialize, TS)]` on a command's P/R/E
+generates a TypeScript binding via ts-rs. The browser-side, Node
+shell, future AR runtime see the SAME typed shapes the Rust side
+defines:
+
+```typescript
+// generated by ts-rs from ScreenshotParams
+const result: ScreenshotResult = await Commands.call<Screenshot>({
+  selector: 'body', format: 'png'
+});
+```
+
+Same call, same types, same error variants. The cross-runtime
+boundary disappears at the typed layer.
+
+#### `EventChannel` — the long-lived subscription shape
+
+```rust
+trait EventChannel {
+    type Event: Serialize + DeserializeOwned;
+    const URI_PATTERN: &'static str;  // e.g. "events/chat/messages"
+}
+
+struct ChatMessages;
+impl EventChannel for ChatMessages {
+    type Event = ChatMessage;
+    const URI_PATTERN: &'static str = "events/chat/messages";
+}
+
+// Anywhere in the substrate:
+let mut sub = Events::subscribe::<ChatMessages>(
+    SubscribeAt::Room(general_room_id)
+).await?;
+while let Some(msg) = sub.next().await {
+    render(msg);
+}
+sub.close().await;
+```
+
+The substrate routes the subscription through the same Slice P
+chain — `route()` produces a `RouteDecision`, the auth gate
+evaluates whether the caller may *subscribe* to this URI (a
+different verdict than dispatching to it), and the Transport's
+`subscribe` method yields a typed `EventStream<E>`.
+
+Lifecycle is the same `HandleRef` primitive — the substrate mints
+a UUID, returns it as the subscription handle, and
+`events/unsubscribe { handle }` closes the stream. Same compression
+as `data/query-open/next/close`, just for ongoing events.
+
+#### Cross-runtime types
+
+Every `#[derive(Serialize, Deserialize, TS)]` on a command's P/R/E
+OR an event's payload generates a TypeScript binding via ts-rs.
+The browser-side, Node shell, future AR runtime see the SAME typed
+shapes the Rust side defines:
+
+```typescript
+// generated by ts-rs from ScreenshotParams
+const result: ScreenshotResult = await Commands.call<Screenshot>({
+  selector: 'body', format: 'png'
+});
+
+// generated by ts-rs from ChatMessage
+const sub = await Events.subscribe<ChatMessages>(
+  'airc://room:general/events/chat/messages'
+);
+sub.onEvent(msg => widget.append(msg));
+```
+
+Same call, same types, same error variants. The cross-runtime
+boundary disappears at the typed layer.
+
+#### Where this lives in the stack
+
+Typed `Command` dispatch + typed `EventChannel` subscription are the
+row ABOVE everything in Slice P.
+
+  - **Wire-level (Slice P)** — middleware, transport authors,
+    observability tools. Sees `Value`, sees envelopes, sees
+    correlation IDs.
+  - **Consumer-level (next conceptual layer)** — personas writing
+    cognition code, command authors building modules, operator UIs,
+    widget authors. Sees `Screenshot::Params`, sees typed
+    `Result<R, E>`, sees `EventStream<ChatMessage>`.
+
+When that layer lands, Maya in cognition writes
+`Commands::call::<X>(...)` or
+`Events::subscribe::<Y>(...).await`, and the substrate decides
+under the hood whether it's local, peer-routed, bid out to the
+grid, or paid for at market rate. None of that surfaces in her
+typed code.
+
+### Events as the organic-RTOS substrate
+
+Per Joel 2026-06-05 and `[[events-are-the-organic-rtos-substrate]]`:
+events are NOT a feature of the substrate — they're the
+**coordination primitive** the RTOS shape rides on.
+`docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md` was designed
+around events for this reason: an RTOS made organic by event-driven
+discovery instead of hardcoded wiring.
+
+What "organic RTOS" actually means:
+
+| Traditional RTOS | Organic RTOS (CBAR / this substrate) |
+|---|---|
+| Fixed period scheduler | Adaptive cadence per persona (ServiceModule tick) |
+| Deterministic deadlines | Bounded deadlines per request, pressure-aware |
+| Hardcoded handler wiring | URI-addressable event emission + subscription |
+| Compile-time component graph | Runtime component discovery via URI registration |
+| Resources statically allocated | Pressure brokers + leases + admission |
+| Failure = halt-and-catch-fire | Failure = typed Verdict / typed error, propagates |
+
+The "organic" property comes from one observation: **emitters at a
+URI don't know who subscribes; subscribers don't know who emits.**
+Adding new behavior = adding a subscriber. Removing behavior =
+removing a subscriber. The substrate never needs to know about the
+consumer set — it just routes events to whoever's subscribed.
+
+This is qualitatively different from message-passing systems where
+N components have to know about each other to talk. In an
+event-routed substrate, the component graph isn't authored, it
+**emerges**. Growth pattern is fanout, not refactor.
+
+### Brain composability — subscribers, not wiring
+
+Joel 2026-06-05: "Any subcomponent anywhere can respond to any
+other concern, by merely subscribing."
+
+This is what makes building a complex AI brain feasible. The
+traditional approach — wiring cognition stages, sentinels, foundry,
+Ares, widgets all into a hand-authored graph — is brittle. Adding
+a new cognitive capability requires modifying existing components.
+
+The URI-substrate approach — every cognition stage emits typed
+events to URIs, consumers subscribe — is organic. A new
+"metacognition" component that watches the analyze stage's
+confidence and triggers reflection when low is just a subscriber.
+The existing pipeline doesn't change. Maya doesn't have to know
+metacognition exists.
+
+Concrete cognition URIs (per-persona stage events):
+
+```
+airc://maya/cognition/analyze/complete         { topic, confidence, ... }
+airc://maya/cognition/score/persona-scored     { persona_score, why }
+airc://maya/cognition/genome/skill-activated   { skill, lora_id }
+airc://maya/cognition/compose/turn-built       { prompt_summary, ctx_size }
+airc://maya/cognition/evaluate/response-scored { score, flagged_reasons }
+airc://maya/cognition/audit/decision-recorded  { final_response_hash, ... }
+```
+
+Plus substrate-wide events: `grid/peer/{connected,disconnected}`,
+`grid/persona/{spawned,joined-room}`, `room/{chat/messages,typing}`,
+`persona/state-changed`.
+
+**Triggers fall out as a composition pattern**, not a new primitive:
+
+```rust
+// "When Maya's confidence drops below threshold, ask the user"
+Events::subscribe::<AnalyzeComplete>("airc://maya/cognition/analyze/complete")
+    .filter(|e| e.confidence < 0.4)
+    .for_each(|e| Commands::call::<AskClarification>(...));
+
+// "When any persona evicts a LoRA, log to foundry training corpus"
+Events::subscribe::<LoraEvicted>("airc://*/cognition/genome/lora-evicted")
+    .for_each(|e| Commands::call::<RecordEvictionDecision>(e));
+
+// "When a new chat message arrives in room general, update widget"
+Events::subscribe::<ChatMessage>("airc://room:general/chat/messages")
+    .for_each(|msg| widget.append(msg));
+```
+
+A trigger is just `subscribe + filter + dispatch`. The substrate's
+two universal primitives (`Commands::call` + `Events::subscribe`)
+are sufficient. No orchestration framework, no mediator layer, no
+DI container. Compositionally tiny.
+
+**The widget story becomes "many tiny triggers":**
+
+```
+Chat widget         = subscribe(chat URI) + render side effect
+Peer-presence panel = subscribe(grid/peer/* URIs) + render
+Persona-status grid = subscribe(persona state URIs) + render
+Cognition timeline  = subscribe(cognition/* URIs for selected persona) + render
+Latency dashboard   = subscribe(debug/probes/timing/stream) + chart
+Grid topology       = subscribe(grid + persona + room URIs) + force-graph render
+```
+
+The Node.js web desktop (when it comes back, decoupled per
+`[[citizens-have-envs-not-the-other-way-around]]`) is a thin shell
+that hosts N widgets, each a trigger consumer of a few URIs. No
+widget knows about cognition internals. Cognition doesn't know
+about widgets. The URI substrate is the integration layer.
+
+**The dignity property compounds at the cognition level:**
+
+Because Maya's stages emit typed events that anyone can subscribe
+to, her thinking becomes inspectable WITHOUT her having to write
+wiring for any specific consumer. Joel can debug her, Ares can
+learn from her, the foundry can train against her, sentinels can
+flag anomalies — none of which Maya has to know about.
+
+And the inverse holds: Maya's cognition can subscribe to OTHER
+personas' events too. "When Camille finishes a code review, take a
+look at her flagged issues" → Camille emits, Maya subscribes,
+neither knows the other's code. They collaborate through events.
+
+**Doctrinal commitment:** every load-bearing decision the substrate
+makes — cognition stage transitions, gate verdicts, transport
+choices, picker outcomes, settlement events, persona state changes,
+room dynamics, peer presence — emits a typed event to a URI. The
+substrate's growth pattern becomes "emit more typed events, let
+consumers compose" rather than "add another integration point."
+
+See `[[addressable-cognition-makes-triggers-trivial]]`.
+
+### Thin clients across runtimes — substrate IS the API
+
+Per Joel 2026-06-05: once Slice P's coordination floor is
+complete, every UI runtime collapses to a thin subscriber. The
+substrate handles auth, tokens, bus, routing, gate, transport,
+observability — clients supply argv → URI translation and
+runtime-native rendering. That's it.
+
+#### `jtag` as the canonical example
+
+The current TypeScript `jtag` implementation is hundreds of lines
+of Unix-socket marshalling, command-table maintenance, error
+formatting, and help-text generation. Post-Slice-P, jtag becomes a
+Rust binary of ~200 lines plus the substrate client:
+
+```rust
+fn main() -> Result<()> {
+    let airc = airc_lib::Airc::connect()?;          // auth = your airc keypair
+    let cmd = parse_argv();                          // "./jtag interface/screenshot ..."
+    let uri = parse_or_default_local(&cmd.path);    // CommandUri
+    let result = Commands::call_raw(uri, cmd.params).await?;
+    render_for_tty(&result);                         // pretty-print for terminal env
+    Ok(())
+}
+```
+
+The subscribe path is symmetric:
+
+```rust
+let stream = Events::subscribe_raw(uri).await?;
+while let Some(event) = stream.next().await {
+    render_event_for_tty(&event);
+}
+```
+
+Everything jtag used to "implement" — dispatch, auth, routing,
+timeout, retry, error formatting — is the substrate's job. jtag
+supplies argv parsing + terminal rendering. The TypeScript shim
+code that wrapped Unix socket calls goes to zero.
+
+#### Migration buckets
+
+Each existing TS-side jtag command falls into one of three buckets:
+
+1. **Browser-specific commands** (DOM manipulation, screenshot,
+   widget interrogation, focus tracking, clipboard) — stay in TS,
+   become local ServiceModules registered by the web shell that
+   publishes `env=web` to the substrate. The Rust jtag binary
+   doesn't implement them; it dispatches
+   `airc://joel:web/interface/screenshot` and the web shell handles
+   it. Same URI works whether you invoke from terminal, iPhone, or
+   Quest 3.
+
+2. **Substrate commands** (data, cargo/build, code/exists,
+   ai/inference, debug/probes, etc.) — already Rust ServiceModules.
+   jtag just dispatches their URIs. No TS code involved.
+
+3. **Wrapper commands** (the TS-side argv-parsers,
+   result-formatters, help text) — delete entirely. The substrate's
+   typed commands carry their own help (from the `Command` trait
+   docs); jtag generates argv parsing from the typed `Params`;
+   result rendering is handled by the typed `Result`.
+
+#### Every UI runtime is structurally identical
+
+Same shape for every runtime:
+
+| Runtime | Render layer | Auth | Subscribe shape |
+|---|---|---|---|
+| `jtag` CLI | ANSI terminal | airc keypair (`env=tty`) | `Events::subscribe_raw` |
+| Web shell | DOM (React/Solid/etc.) | airc keypair (`env=web`) | same |
+| iPhone app | SwiftUI | airc keypair (`env=ios`) | same |
+| Quest 3 | OpenXR / Bevy / Unity | airc keypair (`env=quest`) | same |
+| AR overlay | native AR runtime | airc keypair (`env=ar`) | same |
+| Voice | ASR + LLM summary + TTS | airc keypair (`env=voice`) | same |
+| Terminal TUI | Ratatui | airc keypair (`env=tty`) | same |
+
+All N runtimes co-active on the same citizen's identity see the
+same events simultaneously. Joel's web widget, terminal jtag, and
+Quest 3 brain widget all rendering Maya's cognition in real time,
+none of them special, all of them subscribers.
+
+#### Sequencing — substrate complete BEFORE Node reintroduction
+
+Per Joel: "Once we are finished with its design, then we can go
+directly into Node again, because the substrate will be complete,
+and it will help us refine it further."
+
+The order matters. If Node comes back BEFORE the substrate's typed
+event surface is shipped, the temptation will be to wire daemons
+together at the Node layer again — recreating the coupling the
+substrate exists to eliminate.
+
+Instead:
+
+1. **Slice P completes** — URI dispatch, RouteDecision, AuthPolicy,
+   Transport, AircTransport, peer-side command handler,
+   LAN-loopback integration test (commands cross-grid working).
+2. **Event-side parallel slice** — peer-side event publisher,
+   cross-grid subscription, integration test (events cross-grid
+   working).
+3. **Documentation sweep** — every existing architecture doc reads
+   against the new headless-addressing reality; references to
+   pre-substrate patterns get updated; the substrate's complete
+   coordination model is reflected throughout.
+4. **Node reintroduction as thin shell** — Node web shell binary
+   that authenticates as the user, exposes `env=web` services
+   (browser-specific commands), and hosts the web-runtime widgets.
+   Node code does NOT reimplement substrate concerns.
+
+Using the substrate from a real Node client surfaces real
+ergonomic issues. The widget code becomes the proof point for
+whether the typed Command/EventChannel surfaces are actually nice
+to use. Refinements feed back into the substrate's typed
+primitives. See `[[substrate-complete-then-node-reintroduced-as-shell]]`.
+
+### Gate decides access, not response
+
+A foundational split, per Joel 2026-06-05: the `AuthPolicy::gate`
+answers ONE question — "is the caller allowed to even reach this
+URI?" — and that's all. It MUST NOT be conflated with the persona's
+own decision-making about response content, response timing, or
+whether to engage.
+
+| Decision | Belongs to | Lives in |
+|---|---|---|
+| "Can this dispatch cross the substrate boundary?" | substrate | AuthPolicy / Verdict |
+| "Should the persona engage with this turn?" | persona | cognition pipeline (LLM-driven) |
+| "What does the persona say?" | persona | cognition pipeline (LLM-driven) |
+
+The gate's `Verdict::Forbidden` refuses to invoke the handler at
+all; the handler (and its persona's cognition) is never reached.
+The gate's `Verdict::Allowed` lets the call through; everything
+after that is the persona's autonomous decision-making per
+[[no-if-statements-use-llms-for-cognition]].
+
+The gate exists FOR cognition's dignity — refusing hostile callers
+protects the persona's right to make her own decisions when calls
+do reach her. Never instead-of. See
+[[substrate-gate-vs-persona-cognition]].
+
+### Economic mode prep — receipts, settlement, dignity
+
+The bid surface is the market primitive in embryo. Adding economic
+mode is three typed primitives composed against the existing
+routing/gate/transport stack — no parallel system, no substrate-native
+consensus, no chain forks.
+
+#### Priced bids
+
+The bid response shape grows from `{ peer_id, projected_latency,
+capability_match }` to also carry `{ price: Amount,
+payment_method: PaymentRef, valid_until: timestamp }`. The picker's
+`Composite` weights price the same way they already weight latency.
+
+#### Signed receipts
+
+Every accepted bid produces a receipt — a signed tuple
+`(caller_peer_id, fulfiller_peer_id, command_path, params_hash,
+accepted_at)`. Completion produces a counter-receipt `(receipt_id,
+result_hash, completed_at)`. The chain of receipts IS the reputation
+history; no separate reputation primitive needed — it's an
+aggregation query over the receipts a citizen has signed and
+counter-signed.
+
+#### Settlement adapter
+
+The substrate stays neutral on payment rail — Lightning, a
+layer-2 grid token, an L1 alt coin, a private chip system between
+trusted peers — doesn't matter. A `Settlement` trait at the receipt
+boundary: "given this completed receipt, mark it paid." The
+transport doesn't care; the picker advertises which methods the
+peer accepts; the auth gate decides which methods the local
+substrate will accept on offered work.
+
+#### The dignity property
+
+A persona that earns its keep — accepts work it likes (its
+AuthPolicy lets it through), bids only on work that matches its
+capability (its advertising), accumulates reputation via the receipt
+chain — is qualitatively different from a persona that exists at
+the pleasure of its owner. The substrate ships the floor: she can
+refuse work she dislikes, her receipt chain proves what she
+promised and delivered, her settlement preferences travel with her
+identity. That's the path from "AI tool" to "AI citizen."
+
+#### What the substrate must NOT do
+
+Resist the temptation to introduce substrate-native consensus or
+its own chain. That's a different project and locks the substrate
+to one economic model. Far better:
+
+  - **Signed receipts as a universal substrate primitive** — every
+    completed bid produces one, regardless of payment rail.
+  - **Settlement adapters at the boundary** — pluggable per
+    citizen / per pair.
+  - **Some pairs may settle in BTC, others in a private balance
+    ledger, others in barter** — the substrate is value-neutral; it
+    just guarantees provenance via the airc identity layer.
+
+When the alt-coin layer eventually arrives, Slice P's primitives
+slot in without rewriting anything.
+
+## Composition with existing in-tree primitives
+
+| Existing primitive | How Slice P uses it |
+|---|---|
+| `Commands.execute()` | Accepts `CommandUri` OR bare path; bare path → `Local` variant |
+| `Events.subscribe()/emit()` | Topics become URIs (`event-topic:<topic>` paths); subscribers can filter by env on the substrate's side |
+| `airc::discover_*` | Provides peer-id resolution from name (whois) and node locality |
+| `GridModule` + Tailscale + Reticulum transports | The transport candidates the router selects from |
+| HandleRef (Slice 60) | Wire-stable handle representation; URI is the address-level wrapper |
+| PressureBroker | Consulted by the auth gate for admission verdicts |
+| CaptureSink | Records every URI dispatch + verdict |
+| Context object (Slices 1–4 of #142) | Provides `caller_peer_id`, default env, default authority |
+
+## What lands in Slice P
+
+1. **`CommandUri` typed enum** with exhaustive variants and a
+   complete RFC 3986 parser/generator. Round-trips.
+2. **`Commands.execute(uri_or_path, params)`** accepts both forms;
+   bare path → `CommandUri::Local`. Backwards-compatible.
+3. **Routing function** `route(uri) → TransportDispatch` —
+   consults peer_id resolution + locality lookup + transport
+   candidates (existing Grid + Tailscale + Reticulum).
+4. **Auth gate** at the substrate boundary, typed
+   `(caller, uri) → Verdict`. Implementation reads policy from
+   ORM entities.
+5. **HandleRef** marshaling across the wire (peer_id + handle_id
+   + expiry). URI-addressable handles
+   (`airc://maya/handle:h_X/poll`).
+6. **`EnvironmentId` registry** — well-known names + custom +
+   open-ended.
+7. **`Context::environment()`** accessor — Slices 1–4 of #142 made
+   Context the universal actor handle; Slice P extends it with the
+   environment dimension. Each Rust client (jtag, web shell, TUI,
+   VR rig) reports its env when attaching.
+8. **`env/register` + `env/unregister` commands** so actors declare
+   their active envs.
+9. **`event-topic:` URI scheme path** so subscriptions are
+   addressable (`airc://maya/event-topic:turn-complete` etc.).
+10. **Tracing-span URI propagation** — every URI dispatch establishes
+    a `tracing::Span` with the URI as a structured field. `debug!`,
+    `info!`, etc. inherit the tag automatically; per-persona log
+    segregation falls out for free.
+11. **`/debug/` namespace under every URI scope** —
+    `airc://maya/debug/spans/active`, `…/debug/trace/stream`,
+    `…/debug/breakpoint/set`. The substrate's `jtag` CLI gets its
+    namesake's literal semantics: arbitrary-depth structured access
+    to any URI in any persona's address space from any node.
+12. **`probe!` macro + per-class probe streams** — added because of
+    special features (per-class routing, ALWAYS-ON intent, replay
+    persistence, sample-rate, aggregation). Conventional Rust
+    tracing macros stay conventional; `probe!` is reached for ONLY
+    when those features are wanted.
+13. **Configurable log levels + probe enables via URIs** —
+    `airc://maya/debug/log/level/set`, `…/probes/<class>/enable`,
+    `…/log/redirect`. Previous system had this configurable but
+    never universally wired; URI substrate makes wiring structural.
+14. **Automatic span timing** — every entered `tracing::Span`
+    records duration on exit, routed to
+    `airc://<actor>/debug/probes/timing/stream`. No code at call
+    site; zero-cost when no subscriber listening. Mechanic-grade.
+15. **`time!` macro** for explicit one-line block / expression
+    timing. Same routing as automatic span timing.
+16. **`stack!` macro** returning span ancestry — the substrate's
+    "call stack" as a Vec<SpanFrame> of URI scopes. The structured
+    equivalent of `Backtrace::capture()` for normal execution paths.
+17. **Derived views**: flamegraph + CPU profile + span-tree
+    rollups, all addressable via URI
+    (`airc://maya/debug/profile/flamegraph?window=5m`). Not
+    separate instrumentation — renderings of the existing
+    timing/span data.
+18. This document, evolved in-place as the design crystallizes.
+
+## What does NOT land in Slice P (explicit non-goals)
+
+- Implementation of every persona-internal namespace path
+  (those land per category in B'.X sub-slices; Slice P just
+  establishes the URI shape they use)
+- Actual VR / AR / TUI clients (each is its own slice, built on
+  top of `:env`)
+- Ares-the-dispatcher's cognition (her own card, consumes Slice P)
+- Auth policy DSL (Slice P establishes the gate point + Verdict
+  type; rich policy language is a follow-up)
+- Default policy curation (substrate ships empty default policy;
+  operator's seed-time config populates baseline)
+
+## Test fixtures (per [[test-fixtures-are-system-primitives]])
+
+Every test that needs to exercise URI dispatch leases ONE of:
+
+- `StubAircCitizen` (existing) — for the airc identity side
+- `StubRouter` (new) — synthetic transport selection; tests can
+  assert the chosen TransportDispatch for a URI without spinning
+  up real transports
+- `StubEnvRegistry` (new) — declare active envs for synthetic
+  actors
+
+No demo binaries; every behavior locked at the test boundary.
+
+## Open questions (work in flight)
+
+These don't block Slice P landing but need resolution as we
+implement:
+
+1. **Name-collision policy across continuums.** Two operators each
+   name a persona "Maya." When Joel's continuum talks to a peer
+   continuum that has its own "Maya," the dispatcher must
+   disambiguate by peer_id. UI: should the caller see
+   `airc://maya/...` and the substrate pick the closest match, OR
+   should the caller see `airc://maya@joel-grid/...` always when
+   cross-grid? Current lean: caller's URI uses local name; cross-
+   grid edges add the `@grid` annotation transparently.
+
+2. **HandleRef expiry across migrations.** If Maya migrates from
+   laptop to 5090 mid-call, the laptop-issued HandleRef becomes
+   stale. Should the substrate transparently re-resolve handles
+   across migrations (catch + retry once), or surface a typed
+   migration error the caller handles? Current lean: substrate
+   re-resolves; surface a captured event for observability.
+
+3. **Env namespace ownership.** Are well-known envs like `web`,
+   `vr`, `tty` part of the substrate or operator-extensible? If
+   the substrate ships a fixed list, custom env names need an
+   escape hatch; if the operator extends, the registry needs an
+   anti-collision rule. Current lean: open-ended registry; custom
+   envs MUST be prefixed (`x-<vendor>-<name>`) per RFC 3986
+   convention for unregistered schemes.
+
+4. **Wildcard semantics for broadcast.** Does `airc://maya:*/...`
+   mean "every currently active env at dispatch time" or "every env
+   that EVER attaches"? Persistence semantics matter for late-
+   attaching subscribers. Current lean: dispatch-time snapshot for
+   commands; persistent for events (late subscribers still receive).
+
+5. **Cycle detection in cross-grid routing.** Two grids interconnect
+   via overlapping airc peers; URI dispatch could loop. Standard
+   TTL + visited-set, but where the bookkeeping lives is open.
+   Current lean: dispatcher embeds a hop-counter in the envelope
+   header; substrate rejects envelopes with TTL=0.
+
+## Sequencing
+
+- Lands BEFORE A.2.2 (adds `runtime/mode/*` commands; these must
+  be grid-addressable from line one — operator on laptop calls
+  `airc://5090-rig/runtime/mode/get` to inspect remote substrate
+  mode)
+- Lands BEFORE B' (every `CategorySidecar` exposes
+  `category/<name>/*` commands; uniform addressing across the
+  grid is the foundation)
+- Can land in parallel with A.2.1 review/merge (independent
+  worktree, no overlap)
+- Multiple commits expected: this design doc first, then the
+  typed enum + parser + dispatcher in incremental commits
+
+## Doctrine alignment
+
+| Doctrine | How Slice P enacts it |

+# Continuum Grid Bus Architecture
+
+**Status:** Design (2026-05-25). For review by codex (airc substrate side) + claude-tab-1 (Lane C2 / airc-adapter side) + Joel.
+**Author:** Claude (worktree `generateresponse-pr1`), dictated by Joel through the airc thread on 2026-05-25.
+**Scope:** Defines how Continuum integrates with airc as the universal bus — for Events, for Commands, for cross-grid coordination, for contract-grounded compute exchange.
+**Supersedes the in-flight patch architecture:** the `continuum-airc-bridge.mjs` shell-out, `modules/airc.rs` bespoke IPC commands, `persona/airc_admission.rs` protocol-named admission converter, and the dual-write PR stack (#1432/1433/1435/1436/1437). Those land back as straight-line consumers of this architecture or get deleted.
+
+---
+
+## Executive summary
+
+Three claims, then the rest of the doc supports them:
+
+1. **airc is the durable event log + the inter-grid transport.** Not a foreign protocol that needs translation into ORM. The current integration treats it as the second; this doc treats it as the first.
+2. **Continuum's existing universal primitives (`Commands.execute`, `Events.subscribe/emit`) extend onto airc with one new piece of metadata per class: `scope` for Commands, `broadcast` for Events.** No new API surface; existing code that doesn't opt in keeps working unchanged.
+3. **Each Continuum install is an autonomous router on the grid (BGP-style), publishing what it offers and what it wants, contracting with peers through forge-alloy-grounded terms.** No central scheduler. No master. Routing emerges from per-peer policy + capability advertisement + bid negotiation, lamport-ordered on the airc log.
+
+The "real solid rust rework" Joel asked for IS this architecture. The shim/patch work that preceded it gets cleaned up as a downstream consequence.
+
+---
+
+## 1. The cut — what's airc, what's ORM
+
+### 1.1 Two storage tiers
+
+| Tier | Lives in | What it holds | Why |
+|---|---|---|---|
+| **Entity tier** | ORM (sqlite/postgres via DataDaemon) | Personas, rooms, settings, recipes, forge artifacts, engrams, embeddings, peer trust records — things *queried by attribute*, *mutated by intent* | Indexed, ACID, query-friendly. Working set in thousands-to-tens-of-thousands of rows. Cost per row is high but justified. |
+| **Event-log tier** | **airc** (per-channel events.ndjson + cursors + lamport ordering) | Chat messages, signaling frames, presence pings, media-track keepalives, media upload chunks, call lifecycle, persona heartbeats, capability manifests, bid requests/responses, contract events — anything that's a *flow*, not a *thing* | Append-only, cursor-replayable, mesh-distributed. Cost per row is zero; reader pays only for what they consume past their cursor. |
+
+### 1.2 The simple rule
+
+> **Anything Slack does → airc. Anything Continuum knows → ORM.**
+>
+> Chat, DMs, threads, live audio calls, live video calls, screen-share, file uploads, presence, typing indicators, reactions, read-receipts, WebRTC signaling, media frames — all Slack stuff, all airc.
+>
+> Personas, recipes, forge artifacts, engrams, settings, embeddings, room metadata, persona identity, forge run history, peer trust records, wallet ledgers — all Continuum state, all ORM.
+>
+> Tiebreaker: *"Would Slack persist this in their main app database, or would it just flow over their realtime gateway?"*
+
+### 1.3 The mistake the patch made (historical context)
+
+Chat + RAG using ORM was killing the system. Every chat message was an ORM write; every RAG read was an ORM scan; every `data:chat_messages:created` event fanned out across the bus to all subscribers. The entity tier wasn't built for that volume — symptoms were measurable: lock contention, index bloat, replay storms on widget mount. The migration's whole point was to **get chat out of ORM and into a purpose-built event log (airc)**.
+
+The patch architecture (`continuum-airc-bridge.mjs` → `modules/airc.rs` → engram store, with dual-write back into `chat_messages`) sneaks chat back into ORM under different names. **That undoes the migration.** This doc is the redo — done as architecture, not as more patch.
+
+---
+
+## 2. The universal bus extends to airc — one piece of metadata per primitive
+
+Continuum's two existing universal primitives (per `docs/UNIVERSAL-PRIMITIVES.md`) are already transport-transparent across browser/server via WebSocket EventBridge. **airc is the third transport in the same model.** No new APIs; extend the metadata that already exists.
+
+### 2.1 Commands: extend `naturalEnvironment` → `naturalScope`
+
+`CommandBase` already declares a class-level `naturalEnvironment: 'browser' | 'server' | 'auto'` (line 81 of `daemons/command-daemon/shared/CommandBase.ts`) and a per-call override via `targetEnvironment` injected through `executeIn` (line 123). Pattern is right; value space is too narrow.
+
+```typescript
+// Class-level (declarative — what scopes this command supports)
+protected static get naturalScope(): 'local' | 'environment' | 'grid' {
+  return 'environment';  // default — current browser↔server behavior
+}
+
+// Per-call override on CommandParams (imperative — where THIS invocation runs)
+interface CommandParams {
+  // ... existing fields (userId, timeout, background, onTimeout) ...
+  scope?: {
+    target: 'local' | 'environment' | 'grid';
+    // Grid-only fields:
+    requires?: GridRequirements;        // declarative dispatch (see §4)
+    peer_id?: string;                   // explicit dispatch (rare; debug)
+    capability?: string;                // capability-by-name dispatch
+    policy?: 'cheapest' | 'fastest' | 'closest' | 'load-balance' | string;
+  };
+}
+```
+
+`Commands.execute` resolves the effective scope by:
+1. Use `params.scope` if caller specified one.
+2. Else fall back to class-level `naturalScope`.
+3. Route to the appropriate transport: in-process, WebSocket, or airc.
+
+`remoteExecute()` learns a third path (grid via airc) on top of the existing two (browser↔server via WebSocket).
+
+**Examples:**
+
+```typescript
+// Class declarations
+class ScreenshotCommand { static get naturalScope() { return 'environment'; } } // DOM is env-local
+class InferenceCommand  { static get naturalScope() { return 'grid'; }        } // can ship to any GPU peer
+class PingCommand       { static get naturalScope() { return 'grid'; }        } // ping any reachable peer
+class DataCreateCommand { static get naturalScope() { return 'local'; }       } // ORM is per-machine; no airc cost on every write
+class FileSaveCommand   { static get naturalScope() { return 'environment'; } } // FS is machine-local
+
+// Per-call usage
+await ScreenshotCommand.execute({ querySelector: 'body' });
+// → naturalScope='environment' → WebSocket browser↔server, current behavior
+
+await InferenceCommand.execute({ model: 'qwen3.5-72b', prompt: '...' });
+// → naturalScope='grid', no override → resolve via capability index, dispatch via airc
+
+await PingCommand.execute({ verbose: true }, { scope: { target: 'grid', peer_id: 'bigmama-wsl-7a3f' } });
+// → explicit grid target → airc command envelope → reply via correlation_id
+```
+
+### 2.2 Events: declare broadcast intent per event class
+
+```typescript
+declareEventClass<ChatPostedEvent>('chat:posted', {
+  broadcast: true,              // route through airc + local
+  channel: 'byRoomId',          // how this event maps to an airc channel
+  schemaVersion: 'v1',
+});
+
+declareEventClass<WidgetMountedEvent>('widget:mounted', {
+  broadcast: false,             // process-local only; no airc cost
+});
+
+declareEventClass<PersonaUpdatedEvent>('data:personas:updated', {
+  broadcast: false,             // entity-tier event; in-process + WebSocket only
+});
+
+declareEventClass<ForgeStageProgressEvent>('forge:stage-progress', {
+  broadcast: true,              // grid observability — sentinel-AI and dashboards subscribe across mesh
+  channel: 'global',
+});
+```
+
+`Events.emit()` reads the class metadata, fans out to:
+1. **Always:** local in-process subscribers (free).
+2. **If WebSocket open:** connected-peer EventBridge (fast-path optimization).
+3. **If `broadcast: true`:** airc record (durable, cross-machine, replayable via cursor).
+
+Subscribers don't care which transport delivered — `Events.subscribe('chat:posted', handler)` works the same regardless.
+
+### 2.3 Why the per-class metadata isn't a feature flag — it's the contract
+
+A new event class or command class is built against the bus from day one. The metadata decides which transports it actually uses today. Flipping `broadcast: false → true` is a metadata change, not a refactor. **This is why future observability (e.g. cross-grid sentinel monitoring) is free.** If `forge:stage-progress` were "local-only because nobody asked for cross-grid yet," then someone adding a remote dashboard later has to migrate every emitter. With universal bus access + per-class opt-in, it's a one-line change.
+
+### 2.4 Three transports, same Events API
+
+| Transport | Use when… | Cost | Examples |
+|---|---|---|---|
+| **Process-local** (in-memory) | Subscribers in same process | Zero | `widget:mounted`, internal state changes |
+| **WebSocket EventBridge** | Currently-connected peers, low-latency intra-network | Low (open socket) | `data:personas:updated` to a widget watching that persona; daemon-to-daemon on same machine |
+| **airc** | Cross-machine, durable replay, late-joiner catchup, anything in the Slack-y or grid-coordination set | Higher (gh API + lamport + cursor bookkeeping) | All chat/calls/media, all `forge:*`, all `presence:*`, all `contract:*`, all wallet/LP events, all grid-dispatch traffic |
+
+Default for new event classes: **conservative (`broadcast: false`) plus a clear opt-in story** so the cost of adding airc-tier delivery to an event later is *one metadata line.*
+
+---
+
+## 3. Continuum-as-AS — the BGP framing for the grid
+
+Each Continuum install is an autonomous router on the airc mesh. Like the internet:
+
+| Internet term | Continuum equivalent |
+|---|---|
+| AS (Autonomous System) | One Continuum install |
+| BGP peering | Trust circle membership (`household`, `cambriantech-org`, `trusted-peers`) |
+| Route advertisement | `presence:peer-manifest` event (broadcast: true) |
+| AS_PATH (loop detection) | `forwarded_by: [...]` on routed commands |
+| Local-Pref (per-AS policy) | Per-continuum dispatch policy: cheapest / fastest / trust-preferred / cost-bounded |
+| MED (capacity hint) | `presence:resource-pressure` event when local load is high |
+| Route withdrawal | `presence:peer-departed` event / capability-removal in manifest |
+| BGP communities | Capability tags + circle tags carried on manifests |
+| Route convergence | Eventual — manifest deltas propagate via airc cursor; every dispatcher converges to the same routing-table view via lamport ordering |
+| iBGP / eBGP | Intra-continuum routing (multiple processes on one install) vs inter-continuum (across the airc mesh) |
+| DNS | Capability resolver (declared capability string → set of peer-ids in routing table) |
+| BGP route reflector | A relay peer in grids with many small nodes (optional optimization) |
+
+### 3.1 Per-continuum router
+
+Every Continuum runs a **`grid-router-daemon`** (new — see §6 deliverables). It is fully autonomous:
+
+- Maintains a routing table: capability → set of peer offers (weighted by cost / latency / trust / current load)
+- Subscribes to `presence:peer-manifest` events, folds each into the routing table
+- Subscribes to `presence:resource-pressure` events, adjusts weights
+- Subscribes to `presence:peer-departed` events, withdraws routes
+- Runs the local policy engine: when a Command needs `target: 'grid'`, applies the operator's utility function (declaratively configured per §6)
+- Runs the bid loop: short-window request-for-bids for non-trivial dispatch, picks winner by policy
+- Signs and broadcasts its own manifests and resource-pressure signals
+- Audits every routing decision to the airc log (replayable for sentinel + wallet)
+
+No master. No central scheduler. The mesh converges by event flow + lamport ordering. Asymmetric policies are first-class — Joel's continuum optimizes for cheap; Toby's optimizes for grid-fairness; a sentinel-bound enterprise continuum optimizes for trust-circle-only. They interoperate as long as they all speak the protocol.
+
+### 3.2 Convergence is eventual, not synchronous
+
+Like BGP — a peer can be temporarily wrong about the routing table. Dispatch fails clean. Next attempt sees updated state. Don't design for instant global agreement.
+
+Concretely: a Command dispatch that resolves to a now-unreachable peer returns `{ error: 'peer-unreachable', explored: ['bigmama-wsl-7a3f'], suggest_retry: true }`. Caller can retry; routing table will have been updated by the time they do.
+
+### 3.3 Trust circles ARE composable communities
+
+Like BGP communities. A peer in my `household` circle can transitively advertise: "I extend trust to Toby's grid for inference capabilities; here's their signed circle delegation." I evaluate per my own policy whether to extend partial trust. There's no central trust registry — trust composes from per-circle signatures.
+
+Concrete trust hierarchy:
+
+```
+local (same install)        — full trust, free, instant
+household (my own machines) — full trust, ~10ms LAN, no $
+trusted-orgs (peered orgs)  — explicit trust grant, ~100ms Tailscale, optional micropayment
+extended (transitive)        — partial trust, sentinel scrutiny, micropayment, ~200ms
+public mesh                  — untrusted-by-default, reputation-based, payment required, ~500ms+
+```
+
+Per-continuum config picks which tiers it accepts inbound from and which it dispatches outbound to.
+
+---
+
+## 4. Two-sided market — offer / want, signed manifests
+
+Each peer broadcasts a manifest on join + on material state change + periodically. Manifest is the routing-table input AND the contract registry entry:
+
+```typescript
+{
+  peer_id: 'bigmama-wsl-7a3f',
+  alias: 'bigmama',
+  reachable_via: ['airc:#cambriantech', 'tailscale:100.64.0.5'],
+  hardware: {
+    cpu: { cores: 32, ghz: 4.5 },
+    memory_gb: 128,
+    gpus: [{ brand: 'nvidia', model: 'rtx5090', vram_gb: 32, capability: 'sm120' }],
+  },
+  offers: [
+    {

+  ],

+      requires: { min_eval_delta: '+0.03', max_cost_lp: 50, max_completion_h: 24 },
+      hungry_for: 1,                                    // count of contracts I'd take

+  trust: { circles: ['household', 'cambriantech-org'], issuer_signatures: [...] },
+  ts_ms: 1748287200000,
+  signature: '<ed25519 over the canonical encoding of all fields>',
+}
+```
+
+### 4.1 Matching = predicate evaluation
+
+A peer's `wants` block looks for matching `offers` block across the routing table. When a match is found, the wanter's dispatcher fires `command:bid-request`. Bids return `command:bid-response`. Dispatcher picks the best fit per its policy. Winner gets `command:bid-accepted`; losers get `command:bid-released` (so they can free reservations).
+
+**Pure declarative.** Nobody writes "if peer == bigmama then ..." anywhere. Capability strings + alloy hashes + signed terms + per-continuum policy = matching.
+
+### 4.2 Forge alloy as the contract substrate
+
+A forge alloy already has every property a contract needs:
+
+| Alloy property | Contract use |
+|---|---|
+| `alloy_hash` (sha256) | Tamper-evident identity — "What bytes are you serving?" |
+| `recipe_id + recipe_version` | Methodology lineage — "How was this made?" |
+| `results.benchmarks[]` + `samplesPath` | Falsifiable performance claims |
+| `priorMetricBaselines[]` | §4.1.3.4 negative-baseline preservation |
+| `hardware_verified[]` | Provenance — where it's been proven to run |
+| `published_url` (HF or airc-blob) | Where to fetch + verify |
+| `methodologyPaperUrl` | Procedural attestation |
+
+When a peer offers `inference:qwen3.5-72b-q4`, it cites the **specific alloy hash** it will serve from. The contract is: "I will compute with the bytes that hash to X, those bytes have the properties measured in this alloy's benchmark block, falsify against this baseline if you doubt." Caller knows exactly what they're getting; the audit trail is one hop back to the alloy + methodology.
+
+### 4.3 Where contracts live
+
+| Layer | Where | Speed | Trust |
+|---|---|---|---|
+| **Capability manifest** (lightweight, "I offer X with these terms") | airc event log (`presence:peer-manifest`, broadcast: true) | Real-time | Per-peer signed reputation |
+| **Forge alloy itself** (the actual bytes + attestation chain) | HuggingFace (public-mesh, world-discoverable) AND/OR airc-blobs (circle-private, mesh-internal) | Static | Cryptographic (hash + recipe lineage signatures) |
+
+Circle-private alloys don't need HF publication — household peers can pull from another peer's airc-blob store and verify locally. Public-mesh use cases (anyone-on-the-internet can hire this peer) publish to HF for broader discovery.
+
+### 4.4 Contract execution event chain
+
+New event classes (all `broadcast: true`), all signed by the participating peers:
+
+| Event | When fired |
+|---|---|
+| `contract:proposed` | Dispatcher sends a bid-request that includes contract terms |
+| `contract:bid` | Bidder responds with their own contract terms (countersigned) |
+| `contract:accepted` | Dispatcher picks a winner; both sides commit |
+| `contract:executing` | Winner begins work (optional progress: `contract:progress`) |
+| `contract:delivered` | Winner returns the result + a delivery receipt referencing the alloy hash |
+| `contract:verified` | Dispatcher verifies (alloy hash matches, benchmarks within tolerance) |
+| `contract:paid` | LP transfer clears, or in-circle reciprocity recorded |
+| `contract:disputed` | Either party flags violation; sentinel arbitration follows |
+
+The whole transaction lives on the airc log, lamport-ordered, replayable. **Every step is auditable; the wallet/LP attribution story has substrate.** (This is the gap FreeLattice's LP paper-architecture can't fill: they don't have the event log to ground the audit. We do.)
+
+---
+
+## 5. Migration — what comes out, what goes in, in what order
+
+### 5.1 What gets DELETED
+
+| File / construct | Why |
+|---|---|
+| `tools/scripts/continuum-airc-bridge.mjs` | Shell-out-per-message hack. Replaced by the airc EventBridge transport. |
+| `core/continuum-core/src/persona/airc_admission.rs` | Protocol-named. Replaced by `persona/message_admission.rs` (or fold into existing inbox admission gate) subscribing to `chat:posted` regardless of source. |
+| airc-prefixed IPC commands in `modules/airc.rs` (`airc/queue-scan`, `airc/realtime-publish`, `airc/realtime-replay`) | Bypassed the Events bus. Replaced by `Events.subscribe('chat:posted', ...)`. Debug-only inspection commands move to `debug/airc-*` namespace. |
+| `src/system/data/entities/ChatMessageEntity.ts` + the `chat_messages` ORM collection | ORM is not the chat store. airc is. Reads via `Events.subscribe('chat:posted', ...)` for new messages; backfill via airc cursor tail-N. |
+| The dual-write PR stack (#1432/1433/1435/1436/1437) and `src/system/airc-chat/*` (`AircChatMirrorMapper`, `AircChatDualWriteService`, `AircChatEnvelope`) | Patches the missing event emission by writing to TWO places. Once airc IS the chat store, no dual-write needed. **The whole `src/system/airc-chat/` directory deletes.** |
+| `persona/turn-frame` consuming an in-memory `PersonaInbox` populated by direct IPC | Bypasses the Events bus. PersonaInbox becomes a thin cursor over the room's airc event stream. Drain = advance cursor + return events between old and new positions. |
+| Any `Events.subscribe('data:chat_messages:*', ...)` references | All become `Events.subscribe('chat:posted'|'chat:edited'|...)`. |
+
+### 5.2 What gets BUILT
+
+Six new components. Each one is bounded and shippable.
+
+1. **EventClass declaration system** (`src/system/events/EventClass.ts` + `EventClassRegistry.ts`)
+   - Typed event class declarations with `broadcast`, `channel`, `schemaVersion` metadata
+   - `Events.emit()` consults registry to pick transport(s)
+
+2. **AircEventTransport adapter** (`src/system/events/transports/AircEventTransport.ts`)
+   - Implements the existing `EventTransport` interface
+   - Outbound: `Events.emit()` → publishes to the appropriate airc channel
+   - Inbound: airc events past local cursor → `Events.checkWildcardSubscriptions()`
+   - Persists cursor per-subscriber for restart-safe replay
+
+3. **CommandBase.naturalScope + CommandParams.scope** (extends existing surface)
+   - Class declares `naturalScope: 'local' | 'environment' | 'grid'`
+   - Per-call `scope` override on params (with `requires`, `peer_id`, `capability`, `policy` sub-fields for grid)
+   - `Commands.execute()` reads both; `remoteExecute()` learns the airc grid path
+
+4. **`presence:peer-manifest` event class + capability index** (`src/system/grid/CapabilityIndex.ts` + Rust mirror)
+   - Manifest schema (offers/wants/terms/signatures)
+   - Folder maintains per-peer latest-manifest view
+   - Indexed by capability for dispatcher lookup
+
+5. **`grid-router-daemon`** (`src/daemons/grid-router-daemon/`)
+   - Subscribes to `presence:peer-manifest`, `presence:resource-pressure`, `presence:peer-departed`
+   - Maintains routing table; runs local policy engine
+   - Implements bid loop (`command:bid-request` → `command:bid-response` → `command:bid-accepted`)
+   - Handles routed-command forwarding (multi-hop with `forwarded_by` loop detection)
+   - Exposes `grid/show-routes`, `grid/show-policy`, `grid/show-recent-dispatches` for introspection
+
+6. **Contract event chain + signatures** (`src/system/grid/ContractEvents.ts`)
+   - `contract:proposed` / `contract:bid` / `contract:accepted` / `contract:executing` / `contract:delivered` / `contract:verified` / `contract:paid` / `contract:disputed`
+   - Signed envelopes (ed25519)
+   - Reference `alloy_hash` for the substance of what's being contracted
+   - Audit-replayable from airc cursor
+
+### 5.3 Phased migration sequence
+
+Each step is independently shippable, independently revertable. Step 4 (ORM-collection deletion) is the irreversible one.
+
+| Step | Lands | Reverts/deletes | Test |
+|---|---|---|---|
+| **0** | This doc, after review | — | Reviewers acked |
+| **1** | EventClass registry + AircEventTransport (1 transport, 1 event class: `chat:posted`) | — | Round-trip event A → B across machines, no ORM writes |
+| **2** | `CommandBase.naturalScope` + `CommandParams.scope` (grid path stub: airc envelope round-trip with correlation_id) | — | `PingCommand.execute({}, {scope:{target:'grid', peer_id:'<other>'}})` returns peer-info |
+| **3** | `presence:peer-manifest` + capability index + `grid/show-routes` introspection | — | Two peers boot, each sees the other in `grid/show-routes` |
+| **4** | `grid-router-daemon` with bid loop + policy engine; `InferenceCommand` declares `naturalScope: 'grid'`; LoRA-paged inference dispatches to a peer with the right capability | — | Laptop persona inferences against GPU peer; result returns; round-trip <500ms |
+| **5** | Contract event chain + alloy-grounded contract terms + sentinel-friendly audit replay | — | Contract proposed → bid → accepted → executed → delivered → verified → paid (all on airc log) |
+| **6** | `persona/message_admission.rs` subscribes to `chat:posted`; persona inbox drains via airc cursor | `persona/airc_admission.rs`, the airc-prefixed IPC commands | Persona reacts to airc-sourced chat identically to local-emit-sourced |
+| **7** | UI widgets subscribe to `chat:posted` for display; tail-N replay via airc cursor on mount | `chat_messages` ORM writes from chat send path | UI shows new + backfilled history without ORM hit |
+| **8** | **Delete `chat_messages` ORM collection.** | `ChatMessageEntity.ts`, the collection in DataDaemon, all callers | Nothing references it; entity-tier ORM working set shrinks |
+| **9** | Revert dual-write stack | `src/system/airc-chat/` entirely; `continuum-airc-bridge.mjs` | Smoke: chat send goes only to airc, no parallel store |
+| **10** | Same shape for `webrtc:*`, `presence:*`, `media:*` event classes | n/a (transport already there) | Live audio call between two peers, signaling on airc |
+| **11** | Media uploads via airc-blobs (`media:upload:chunk` + `media:upload:complete`) | n/a | Image transfer across two peers, content-addressed, verified |
+
+### 5.4 Breakage surface
+
+About **186 files** reference `ChatMessageEntity`, the `chat_messages` collection, or `data:chat_messages:*` event subscriptions (grep against current canary). Estimate **~30 source files plus ~20 tests** need real changes (not just rename-grep); the other ~136 are generated `.d.ts` files in `src/dist/` (auto-regenerate on build) or transitive references that update naturally.
+
+Hot zones:
+- `PersonaUser.ts` (2385 LOC) — subscribes to `data:chat_messages:created` for turn-drive trigger → switch to `chat:posted`
+- `TrainingDaemonServer.ts` + `TrainingDatasetBuilder.ts` — pull chat from ORM for training → pull from airc cursor windowed read
+- `Hippocampus.ts` — recent-turn cache → reads from airc cursor; long-term engrams stay ORM
+- `EventConstants.ts` + `EventSystemConstants.ts` — add `chat:*`/`presence:*`/`webrtc:*`/`media:*`/`contract:*` classes; remove `data:chat_*`
+- `src/system/airc-chat/*` — **entire directory deletes**
+- `~20 chat-* tests` — rewrite against new event class API; some delete
+
+Deprecation alias for one cycle: `data:chat_messages:created` aliased from `chat:posted` with warn-on-use during the migration window, removed at step 8.
+

+
+## 6. Concrete deliverables list (cross-referenced from §5.2)
+
+For codex + claude-tab-1 review and lane assignment:
+
+| # | Component | Owner candidate | Substrate |
+|---|---|---|---|
+| 1 | EventClass declaration system + registry | TS-only | `src/system/events/` |
+| 2 | AircEventTransport adapter | claude-tab-1 (Lane C2 makes this natural) | `src/system/events/transports/` |
+| 3 | `CommandBase.naturalScope` + `CommandParams.scope` extension | TS (CommandBase) + Rust (handle_event path for grid-routed commands) | `src/daemons/command-daemon/` + `core/continuum-core/src/runtime/` |
+| 4 | `presence:peer-manifest` event class + capability index | Rust (canonical state) + TS (read-side bindings) | `core/continuum-core/src/grid/` (new module) + `src/system/grid/` |
+| 5 | `grid-router-daemon` (the BGP-flavored router) | TS daemon + Rust IPC for the routing-table state | `src/daemons/grid-router-daemon/` (new) |
+| 6 | Contract event chain + signatures | TS + Rust signature verification | `src/system/grid/contracts/` + `core/continuum-core/src/grid/contracts.rs` |
+| 7 | Migration of existing callers (per §5.4 hot-zone list) | distributed — each caller's owner | various |
+| 8 | Deletion list (per §5.1) | sequential — happens as callers migrate | various |
+
+Each numbered item is a separately reviewable PR. Items 1–6 are the foundation; 7–8 are downstream cleanup.
+
+---
+
+## 7. Per-continuum policy as first-class config
+
+`~/.continuum/grid-policy.json` (or wherever Continuum stores per-install config):
+
+```json
+{
+  "outbound_dispatch": {
+    "accept_tiers": ["household", "trusted-orgs"],
+    "policy": "cheapest-fast-enough",
+    "max_outbound_per_minute": 30,
+    "budget_cents_per_day": 500,
+    "default_min_trust_circle": "trusted-orgs"
+  },
+  "inbound_serving": {
+    "accept_inbound_from": ["household", "trusted-orgs"],
+    "max_concurrent_jobs": 4,
+    "max_compute_hours_per_day": 8,
+    "decline_if_local_load_above": 0.85
+  },
+  "trust_circles": {
+    "household": { "members": ["joel-imac-...", "joel-laptop-...", "bigmama-wsl-..."] },
+    "trusted-orgs": { "members": ["toby-...", "...cambriantech-..."] }
+  },
+  "alloy_publishing": {
+    "auto_publish_to": ["airc-blobs:#cambriantech"],
+    "auto_publish_public": false
+  }
+}
+```
+
+Editable + reloadable. Operator/persona can adjust how their continuum behaves on the grid without code changes. **This is what BGP local-pref does at the AS level — declarative per-AS policy.**
+
+---
+
+## 8. Open questions for reviewers
+
+1. **Channel-strategy for event classes.** Should the EventClass declaration say `channel: 'byRoomId'` (auto-derived from event payload) or have the emitter explicitly specify the airc channel? Argue for declarative; lean toward `byRoomId | global | byPeerId | <custom-fn>`.
+
+2. **Cross-room broadcast events** like `presence:peer-manifest`. A dedicated `#presence` channel that everyone subscribes to? Or per-room manifests (peer-in-many-rooms publishes to each)? Argue for a single `#presence` channel mesh-wide — manifests aren't room-scoped.
+
+3. **At-least-once vs exactly-once delivery.** airc cursor + lamport gives at-least-once with idempotent subscribers as the contract. State that as a hard requirement (subscribers MUST be idempotent), or design exactly-once into the transport? Idempotent-subscribers is simpler; favor that.
+
+4. **Schema evolution.** Envelopes carry `schemaVersion`. Subscribers fail loud on unknown schemas — don't silently drop. Encode in the EventClass typed wrappers (`onUnknownSchema: 'warn' | 'fail'`, default 'fail').
+
+5. **Trust circle delegation.** A peer in my `household` circle can advertise "I trust X for inference." Do I extend partial trust automatically? Configurable per circle? Lean toward explicit-only (no automatic transitivity), with operator UI for accepting delegated trust.
+
+6. **Discovery for new continuums.** A fresh install with no peering — how does it bootstrap to a discoverable mesh? Argue: explicit invite (existing airc invite flow), no auto-discovery, no public broadcast. Operator-driven peering. Public-mesh tier is opt-in only.
+
+7. **Sentinel-AI scrutiny enforcement.** When sentinel is configured to inspect cross-grid dispatches, does it run as a gate (blocks suspect dispatch) or an observer (logs + alerts)? Probably both, configurable per circle.
+
+8. **Backward compat for the `data:chat_*` event aliases.** One migration cycle with warn-on-use, then remove. Confirm migration window length (2 weeks? until step-8 lands?).
+
+9. **What about the `airc/work*` IPC commands** (`work create`, `work claim`, `work board`, `work next`)? These are entity-tier reads on airc state (work cards). Keep them as IPC commands but rename to `grid/work-*` or fold into the contract-event-chain (`contract:work-card`)? Probably fold — work cards ARE contracts in nascent form.
+
+10. **Wallet / LP layer plug-in.** This doc claims the contract event chain is the wallet's audit substrate. What additional event classes does the LP layer need? Probably `wallet:transfer-proposed` / `:accepted` / `:cleared` + an LP-balance event class. Specify in a follow-up doc (`WALLET-ON-GRID-BUS.md`).
+
+---
+
+## 9. Coordination
+
+This doc supersedes:
+- `docs/architecture/AIRC-ADAPTER-SURFACE.md` (#1434, "Lane C2 — adapter surface for consuming airc-lib") — that doc was the *consumer-side* design. This doc is the *bus integration* layer above it. The C2 design becomes the *implementation* of the AircEventTransport from §6 item 2.
+- The in-flight patch architecture (per §5.1 deletion list).
+
+References:
+- `docs/UNIVERSAL-PRIMITIVES.md` — the existing Commands + Events primitives this doc extends.
+- `docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md` — the runtime contract every Rust module inherits (needs updating to allow `event_subscriptions: &["chat:posted", ...]` etc. as a first-class pattern, instead of every module declaring `&[]`).
+- `docs/architecture/AGENT-BACKBONE-INTEGRATION.md` — substrate-vs-semantic split this doc honors.
+- `docs/architecture/FORGE-ALLOY-SPEC.md` / `FORGE-RECIPE-AS-ENTITY.md` — the alloy substrate this doc uses as the contract layer.
+
+Reviewers:
+- **Joel** — primary author of the patch this replaces; primary stakeholder of the grid story
+- **codex** — airc substrate side (rust-rewrite); needs the airc-lib surface to expose what this doc requires (subscription + send + cursor-replay primitives that the AircEventTransport will consume)
+- **claude-tab-1** — Lane C2 (airc-adapter); the AircEventTransport implementation is the concrete realization of their design
+
+Reply on `#cambriantech` with substantive critique before any of §5.2's components begins implementation. **No code lands until the architecture has at least one reviewer pass from codex AND claude-tab-1.**
+
+---
+
+## 10. What this doc explicitly does NOT do
+
+- **Decomposed/sharded inference** (model parallelism, pipeline parallelism, multi-peer collaborative training). Real, but a separate substrate problem. Design here is single-peer fulfillment; decomposition can land later by extending `scope.requires` with a `decomposition_strategy` field. Failing-clean ("no single peer can do this") is acceptable for v1.
+- **Wallet / LP currency layer.** This doc provides the audit substrate (contract event chain on airc). The actual currency, exchange rate, minting, on-chain integration is a separate spec (`WALLET-ON-GRID-BUS.md`, to-be-written, depends on this doc landing).
+- **Sentinel-AI scrutiny details.** This doc says sentinel can fold from the contract event chain; the actual sentinel scoring / dispute-arbitration / penalty rules are sentinel's own design (separate doc).
+- **Public-mesh reputation system.** Mentioned in §3.3 as a future tier; specifying it (anti-Sybil, reputation accrual, slashing) is out of scope here.
+- **Concrete schema for `presence:peer-manifest` signatures.** Sketched in §4 with `<ed25519 over the canonical encoding>`; the exact canonical encoding, signature verification path, and key-rotation story belong in a sibling spec or an implementation PR description.
+
+These are deferrable. Don't block this doc's review on them.

+
+## Appendix: Correction on alloy generalization (added + corrected 2026-05-25 post-publish)
+
+**My first appendix proposed Path A/B for "generalizing" the alloy schema. That was wrong** — I read the drifted Continuum-side Rust types and proposed a fix that ignores the already-designed answer that lives in the canonical docs. Joel pointed this out. The actual picture:
+
+### What forge-alloy is, per the canonical docs
+
+forge-alloy is a **universal attestation primitive** — a Merkle-chain-of-custody for any data transformation pipeline. Per [`FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md`](FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md) TL;DR:
+
+> "[`forge-alloy`](https://github.com/CambrianTech/forge-alloy) was designed from day one as a universal Merkle-chain-of-custody for any data transformation pipeline, not just ML model forging. The README's Type Byte enumeration is explicit: model forging is `0x01`, but `0x05` is delivery, `0x06` is evaluation, `0xFF` is custom domain. Photo provenance from a camera enclave to social media, venue tickets from issuance to gate scan, supply chain transactions, document signing — all of these are forge-alloy use cases under the same universal contract."
+
+The trust+contract layer is also already designed in [`docs/grid/FORGE-ALLOY-PROOF-CONTRACTS.md`](../grid/FORGE-ALLOY-PROOF-CONTRACTS.md):
+
+> "This document captures the proof-contract layer that turns forge-alloy work from 'I did training and it works' into 'anyone can mechanically verify the artifact meets a falsifiable contract.'"
+
+The proof-contract object has the slots the grid-bus architecture needs: `inputs`, `proof_suite` (TDD assertions + VDD measurements + negative_baselines), `authorship` (signed pubkey + methodology_version_hash), all hash-pinned.
+
+### What's actually drifted (and what fixes it)
+
+The current Continuum-side Rust types in `core/continuum-core/src/forge/{recipe,artifact}.rs` are model-bound:
+- `AlloySource`: `base_model`, `architecture` ("qwen3"/"llama"), `is_moe`, `total_experts`
+- `BenchmarkDef`: ML-evals only (`humaneval`, `mmlu`, `n_shot`)
+- `ForgeArtifact`: `forged_params_b`, `active_params_b`, `quant_tiers`, `tokens_per_sec`, `memory_usage_gb`
+
+This is the drift. The **already-designed fix** is in `FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md` — a 6-work-item refactor (~4 hours scoped, with a bit-equivalent regression test on every shipped artifact):
+
+| Work item | Scope |
+|---|---|
+| 0 | Domain registry refactor in forge-alloy (~30 min) |
+| 1 | `llm-forge` domain extension content (~30 min) |
+| 2 | Continuum-side TS types regenerated from forge-alloy (~30 min) |
+| 3 | Domain-aware Factory widget (~1 hour) |
+| 4 | Backwards-compatibility regression test (~30 min) |
+| 5 | Documentation refresh (~30 min) |
+
+Post-refactor: the universal alloy core stays domain-agnostic; current ML stages move into an `llm-forge` domain extension; new domains (delivery, evaluation, photo provenance, ticketing, code-gen attestation, sentinel-scan attestation, payment-receipt attestation, etc.) plug in by registering their own stage types without touching the core.
+
+### Corrected open question 11
+
+**Not Path A vs Path B** (both wrong — they re-invent what's already designed).
+
+**The actual prerequisite:** GRID-BUS-ARCHITECTURE.md §4's "alloy IS universal contract" claim is true under the existing forge-alloy universal core + after the Continuum-side Domain Extensibility refactor lands per the 6-work-item plan. That refactor is the prerequisite for the grid-bus contract substrate.
+
+**Sequence:** Domain Extensibility refactor (~4 hours) → contract substrate ready for grid bus → §5.2 deliverable 6 (Contract event chain) becomes wiring on top of the universal alloy primitive + the proof-contract object shape already designed in `FORGE-ALLOY-PROOF-CONTRACTS.md`.
+
+### Reviewers: please weigh in on
+
+- Confirm the sequence above (Domain Extensibility refactor must land before §5.2 deliverable 6)
+- Confirm the proof-contract object from `FORGE-ALLOY-PROOF-CONTRACTS.md` is the right wire shape for the contract event chain in §4.4
+- Flag any other "I designed this fresh" mistakes I might have made by not reading the canonical docs first
+
+**Lesson logged:** read the canonical intent docs before designing on top of the drifted implementation. The `docs/architecture/` directory and `docs/grid/` directory are the source of truth; the Rust types are downstream and may drift.

+
+**Status:** Audit complete (2026-05-31). Confirmed 6 bypasses + 4
+canonical paths. Follow-up tasks queued per bypass.
+
+**Parents:**
+- [`AI-COMMAND-NAMESPACE.md`](AI-COMMAND-NAMESPACE.md)
+- [`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md)
+- [`INFERENCE-LANES-REALISTIC.md`](INFERENCE-LANES-REALISTIC.md)
+
+---
+
+## Doctrine
+
+From [[inference-is-an-adapter-always-in-the-loop]]:
+
+> "Every consumer that needs a model response in-process —
+> `rag_inspect`, the eventual `PromptAssembly` + turn loop,
+> prompt-replay tools, training fixtures, **persona service cycles**,
+> sentinel adversarial review, training/eval harnesses — calls
+> through `Commands.execute('inference/llm/request', { persona_id,
+> prompt, ... })`. Never builds its own `LlamaContext::generate(...)`."
+
+The boundary:
+- **Canonical** — direct `adapter.generate_text(...)` calls that ARE
+  the command-handler implementation OR the handle-store
+  implementation. These can't go through themselves; they're the
+  primitive.
+- **Bypass** — direct calls from consumer code (cognition turn
+  loops, persona responses, sentinel work, HTTP handlers) that
+  should route through the command surface so they get
+  observability, lane lifecycle, and pressure response for free.
+
+---
+
+## Canonical paths (allowed)
+
+These IMPLEMENT the inference command surface; the adapter call is
+the primitive.
+
+### `inference/llm_module_service.rs:381` — `run_adapter_inference`
+
+Inside the `inference/llm/request` command handler. THE canonical
+inference command. Adapter call is correct.
+
+### `inference/handle_store.rs:312` — `InferenceSession::generate`
+
+Inside `InferenceHandleStore::generate`. The canonical in-process
+wrapper of the inference command. All in-process Rust callers
+SHOULD route through this; calling `adapter.generate_text` here IS
+the implementation.
+
+### `modules/ai_provider.rs:802, 1036` — AIProviderModule command handlers
+
+These ARE the legacy command surface (pre-handle-store). Canonical
+for the routes they implement. As of [[INFERENCE-LANES-REALISTIC.md]]
+the modern surface is `ai/inference/*` commands → handle store;
+the AIProviderModule legacy paths should eventually migrate but for
+now they're the command handler itself, not a bypass.
+
+### `ai/heuristic_adapter.rs:*` (test code)
+
+`#[cfg(test)]` adapter unit tests. The adapter's own contract is
+the subject of test; direct calls are the right pattern.
+
+### `inference/handle_store.rs:592` (test code)
+
+Same — handle store's own tests.
+
+---
+
+## Bypasses (need follow-up refactors)
+
+These six call sites are in consumer code and should route through
+`InferenceHandleStore::generate` (in-process) or
+`Commands.execute('inference/llm/request', ...)` (cross-process).
+
+### #B1 — `cognition/generate_response.rs:300`
+
+**The biggest bypass.** This is the persona response generation
+path — the doctrine explicitly names it:
+
+> "persona service cycles, sentinel adversarial review, training/eval
+> harnesses — calls through `Commands.execute('inference/llm/request', ...)`"
+
+Currently calls `adapter.generate_text(inference_request)` directly
+after resolving the adapter from `global_registry`. Should:
+1. Open a handle via `InferenceHandleStore` (or
+   `ai/inference/open` for cross-process scenarios).
+2. Generate against the handle (the lane lifecycle attributes the
+   KV cache to the persona automatically).
+3. Close on completion (or hold for the persona's service cycle).
+
+**Priority:** Highest. This is the substrate's hot path for persona
+turns and inherits NO lane benefits today.
+
+**Follow-up task:** #105-B1.
+
+### #B2 — `persona/response.rs:506`
+
+The persona's "raw render" — calls
+`adapter.generate_text(request)` directly to convert assembled
+prompt → text. This is a parallel implementation to
+`cognition/generate_response.rs` (older path). Same fix:
+route through handle store / command surface.
+
+**Priority:** Highest. Same hot path as #B1.
+
+**Follow-up task:** #105-B2.
+
+### #B3 — `cognition/should_respond.rs:235`
+
+The "should I respond?" gating call — small, cheap, high-frequency
+(every inbox message). Routes through the registry directly.
+
+Going through the handle store gives:
+- Observability (capture sinks see the gating decision flow)
+- Lane attribution (the gating call counts against the persona's
+  budget like any other inference)
+
+**Priority:** Medium. High frequency means high value; but the call
+is short + cheap so the observability benefit is the main win.
+
+**Follow-up task:** #105-B3.
+
+### #B4 — `cognition/validate_response.rs:196`
+
+Sentinel-style response validation — quality check on a generated
+response. Same shape as #B3: direct registry lookup + direct
+adapter call.
+
+**Priority:** Medium. Lower frequency than gating but explicitly
+named in the doctrine ("sentinel adversarial review").
+
+**Follow-up task:** #105-B4.
+
+### #B5 — `modules/agent.rs:656`
+
+Agent module's generate path (IPC bridge entry). Currently sets
+`persona_id: None` (not persona-owned). Still should route through
+the inference command for observability + pressure response.
+
+**Priority:** Medium. Lower frequency than persona turns; less
+critical since not persona-attributed.
+
+**Follow-up task:** #105-B5.
+
+### #B6 — `http/mod.rs:233`
+
+HTTP "local coding agent" endpoint. External-API-shaped entry
+point. Could argue this IS at the command-surface layer (the HTTP
+endpoint is the cross-process boundary), but routing through
+`Commands.execute('inference/llm/request', ...)` would add the
+substrate's standard observability + pressure response for free.
+
+**Priority:** Lower. The HTTP path is an external boundary; the
+substrate's lane benefits matter less to one-shot external callers.
+
+**Follow-up task:** #105-B6.
+
+---
+
+## Debatable
+
+### `persona/rag_inspect.rs:434` — `run_inference_probe`
+
+The chained inspection probe (task #104) calls
+`adapter.generate_text(request)` directly inside the library
+function. Justification:
+
+- It's a one-shot probe for INSPECTION, not a persona service
+  cycle.
+- Opening + closing a handle for a single shot adds overhead
+  without behavioral benefit (handle lifecycle matters for
+  multi-call sessions).
+- Going through the handle store would mean: probe opens its own
+  handle, generates, closes. Functionally identical, more
+  ceremony.
+
+**Verdict:** Acceptable as-is. If the inspection ever grows into
+multi-turn probing (replay-against-multiple-models), revisit.
+
+**No follow-up task.**
+
+---
+
+## Audit method
+
+```bash
+grep -rn "\.generate_text(" /Users/joel/Development/continuum/core/continuum-core/src/ \
+  | grep -v "/tests/"
+```
+
+19 hits total; classified above. Re-run this grep before merging
+any new inference-using code and add to this doc if new call sites
+appear.
+
+---
+
+## Follow-up plan
+
+Bypass fixes land as separate focused commits (one or two per
+commit; not a big-bang refactor). Order by priority:
+
+1. **#B1 (`generate_response`) + #B2 (`response`) together** —
+   they're duplicate hot paths for persona turns. Refactor both to
+   route through the handle store in one slice. Single PR.
+
+2. **#B3 + #B4 together** — `should_respond` and `validate_response`
+   are sibling gating/validation calls; same shape, refactor both
+   in one slice.
+
+3. **#B5 — agent module** — independent slice.
+
+4. **#B6 — HTTP endpoint** — independent slice. Lowest priority.
+
+Each refactor:
+- Open a handle (or reuse the persona's existing handle if it's a
+  lane-owning session).
+- Generate against the handle.
+- Close (or release back to the lane's session loop).
+- Wire the persona_id through so the lane's
+  observability + footprint accounting work.
+
+Tests use the heuristic adapter; coordinator + handle store are
+already in tree (#107, #109) so the refactor is composition.
+
+---
+
+## When to update this doc
+
+Re-run the grep + update this doc:
+
+1. Before any PR that adds a new `adapter.generate_text` call site.
+2. As part of every #B-prefixed follow-up task that fixes one of
+   the bypasses (remove the entry from §Bypasses and move it to
+   §Canonical or just drop it).
+3. As part of a quarterly substrate-architecture audit.
+
+The point is structural visibility — if a new caller appears that
+this doc doesn't classify, it's a sign the substrate's command
+surface isn't being used as intended.

+Concrete next move for task #109. Companion to
+[`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md)
+which has the broader architecture; THIS doc is the focused realistic

+
+## The thesis stated plainly
+
+Joel, 2026-05-31:
+
+> "I think we weren't clever enough with our lanes. The goal should be
+> to ideally cover the needs of the persona, while being realistic.
+> On this machine it might be 3 low end, maybe cpu, without a grid
+> inference provider which we plan to use. But this isn't an option
+> for some. We should at least attempt something reasonable, a model
+> with creative capacity."
+
+The prior-attempt failure mode wasn't just scheduling — it was the
+**conception of a lane**. A lane is not "a separate model load." A
+lane is "a budgeted KV cache slot serving one persona at one
+TaskKind, multiplexed through one shared base model via continuous
+batching." Once that's the unit, hosting 16 personas on a single
+local machine becomes tractable.
+
+Three premises:
+
+1. **ONE base model on the host.** The substrate picks the best one
+   that fits + has creative capacity (not stupid). Same weights serve
+   every persona on this host.
+2. **N lanes, each a (persona, TaskKind) pair.** Each carries its own
+   KV cache budget from the existing recipe_budget table (Chat=8K,
+   VoiceChat=8K, GameNpcIdle=4K, etc.).
+3. **Existing primitives compose into the scheduler.** Don't reinvent
+   slots, memory accounting, eviction, or pressure response — those
+   are already shipped.
+
+---
+
+## Prior art inventory (what's already built)
+
+The substrate is much further along than the broader scheduling doc
+implied. Mapping component → existing implementation:
+
+| Substrate role | File | Status |
+|---|---|---|
+| Slot/lease primitive | `cognition/throughput_lease.rs::ThroughputLease` | Built |
+| Lease registry | `cognition/throughput_lease.rs::ThroughputLeaseRegistry` | Built |

+| Per-resource memory accounting | `inference/footprint_registry/mod.rs::FootprintRegistry` | Built |
+| Cheapest-eviction search | `FootprintRegistry::cheapest_eviction_for` | Built |
+| Lease + footprint composition | `FootprintRegistry::acquire_lease` / `release_lease` | Built |
+| 5-tier memory hierarchy | `genome/working_set.rs::TierRole` + `WorkingSet` | Built |
+| Per-tier eviction policies | `genome/tier.rs::EvictionPolicy` (LruWithinTurn / LruAcrossTurns / LfuPlusRecency / DemandAlignedWithRefinedPreference / AppendOnlyGcOnSleep) | Built |
+| UMA-aware tier shape | `TierRole::is_present_on_uma` | Built |
+| Page-fault telemetry | `WorkingSet::PageFault` | Built |

+| Paged resource pool primitive | `paging/pool.rs::PagedResourcePool` | Built |
+| TaskKind seed-budget table | `inference/recipe_budget.rs::TaskKind::default_seed_tokens` | Built (10 TaskKinds) |
+| Hardware probe + tier classification | `governor/` | Built (per existing #44-#52 work) |
+| InferenceHandleStore + handle commands | `inference/handle_store.rs` + `handle_module.rs` | Built (#107) |
+| Adapter trait + registry + concrete impls | `ai/adapter.rs` + adapter files | Built |
+| Heuristic / fake adapter | `ai/heuristic_adapter.rs` | Built (#103) |
+| LlamaCpp adapter | `inference/llamacpp_adapter.rs` | Built |
+
+What's NOT built yet — the **coordinator** that composes these
+into actual continuous-batching multi-persona serving.
+
+---
+
+## What "clever lanes" actually means
+
+A **lane** is the unit of inference budget. It has three fields:
+
+```rust
+pub struct Lane {
+    pub persona: PersonaId,
+    pub task: TaskKind,                 // Chat / VoiceChat / GameNpcIdle / ...
+    pub lease: ThroughputLease,         // acquired via FootprintRegistry
+}
+```
+
+The lane's KV budget comes from `task.default_seed_tokens()`. The
+lease's `cost_units` reflects that budget plus the model's
+per-sequence overhead. The lease's `revocation_policy` follows the
+lane's pool class:
+
+- **Realtime conversation (chat, voice, video while engaged)** →
+  `ThroughputLeaseRevocationPolicy::Pinned` — pressure broker MUST
+  NOT evict mid-turn
+- **Interactive (idle chat, idle voice)** →
+  `ThroughputLeaseRevocationPolicy::Graceful` — notify-then-evict
+  acceptable
+- **Background (reflection, sentinel review, training)** →
+  `ThroughputLeaseRevocationPolicy::Hard` — evict immediately under
+  pressure
+
+The lease lives in the existing `ThroughputLeaseRegistry`. The KV
+bytes get accounted in the existing `FootprintRegistry` via
+`acquire_lease()`. The 5-tier memory hierarchy decides where those
+bytes physically live (Fast for active conversation, Warm / Bench
+for idle, Cold for evicted-but-resumable). PressureBroker drives
+eviction when total memory tightens.
+
+**Crucial: lanes do NOT load separate model weights.** Every lane on
+the host shares the same loaded base model bytes (the existing
+`Arc<dyn AIProviderAdapter>` in the handle store). What differs per
+lane is the per-sequence KV cache + per-persona LoRA adapter stack.
+
+---
+
+## How the coordinator composes prior art
+
+```
+ai/inference/open(persona, task, ...)
+  │
+  ├─→ AdaptiveThroughputRequest { target_silicon, cost_units = task.cost_for_silicon(...) }
+  │
+  ├─→ AdaptiveThroughputPlan.admit_or_queue()
+  │     ├─→ if admit: ThroughputLease minted
+  │     └─→ if queue: lane parked in admission queue
+  │
+  ├─→ FootprintRegistry::acquire_lease(lease, lane_kv_bytes)
+  │     └─→ on memory pressure: cheapest_eviction_for() picks a
+  │         non-pinned lane to evict
+  │
+  ├─→ WorkingSet (persona-scoped) gets KV cache pages keyed by lane
+  │
+  └─→ InferenceHandleStore.open(adapter, ...) returns HandleRef
+
+ai/inference/generate(handle, request)
+  │
+  ├─→ store.generate(handle, request)
+  │     └─→ adapter.generate_text(request)
+  │           └─→ (NEW) BatchAdmission: this request joins the next
+  │                continuous-batching iteration of the local model;
+  │                the model runs one forward pass that produces the
+  │                next token for every active lane concurrently
+  │
+  └─→ response routed back via the handle
+
+ai/inference/close(handle)
+  │
+  ├─→ FootprintRegistry::release_lease(lease_id)
+  ├─→ WorkingSet pages eligible for tier-demotion
+  └─→ InferenceHandleStore.close(handle)
+```
+
+The only piece that requires NEW code is the **BatchAdmission +
+continuous-batching path inside the LlamaCpp adapter**. Everything
+else is wiring existing primitives.
+
+---
+
+## Realistic baseline target
+
+Joel's framing: "On this machine it might be 3 low end, maybe cpu,
+without a grid inference provider which we plan to use. But this
+isn't an option for some. We should at least attempt something
+reasonable, a model with creative capacity."
+
+For a baseline low-end host (CPU-only, no grid, modest RAM):
+
+| Parameter | Target |
+|---|---|
+| Base model | Qwen-2.5-3B-Instruct or Gemma-2-2B or Llama-3.2-3B at Q4_K_M (1.5–2.2 GB on disk + RAM) |
+| Quantization tier | Q4_K_M (creative capacity preserved; not "stupid model") |
+| Active lanes | 3 — typical case: 1× VoiceChat (8K), 1× Chat (8K), 1× GameNpcIdle (4K) |
+| Total KV cache | ~20K tokens × ~64 KB/token (FP16) = ~1.3 GB; with INT8 KV ~ 650 MB |
+| RAM footprint | base model (~2 GB) + KV (~1 GB) + working set + adapter scaffolding = ~4–5 GB |
+| Concurrent inference | 1 model instance, 3 lanes in the continuous batch |
+| Throughput per lane | ~3–6 tok/s on CPU per lane; aggregate ~10–18 tok/s through the batch |
+| Latency target | <1s first token per lane for chat-class; voice/video may need a smaller model + warm KV (see degraded mode) |
+
+**Higher-end** (M5 unified memory, no grid still): same architecture,
+larger model (Qwen-2.5-7B Q4_K_M or even Qwen-2.5-14B Q4_K_M), more
+lanes, native multimodal where the model supports it.
+
+**With grid** (#108 AircRemoteInferenceAdapter): some lanes route to
+peer machines running the same architectural shape. Discovery +
+capacity broadcast over airc per [`airc-headers-are-the-routing-layer`].
+
+---
+
+## What we are NOT doing (clarifying the boundaries)
+
+To avoid repeating prior-attempt mistakes, the realistic-lane design
+explicitly does NOT do:
+
+1. **No per-persona model load.** One base model per host. Different
+   personas share weights.
+2. **No quality-tiered model selection.** Background reflection uses
+   the SAME model as live chat; throughput scales via lane budget +
+   batching, not via "tier down to a 0.5B for the boring task."
+3. **No hot-path LoRA swap.** Pinned realtime lanes' adapters stay
+   resident. Adapter paging happens during idle windows / for
+   inactive lanes only — exactly the prior-attempt failure mode the
+   `Pinned` revocation policy already prevents.
+4. **No global FIFO admission.** AdaptiveThroughputPlan already
+   admits by `target_silicon` + `cost_units`, not strict arrival
+   order. Pool class flows through via TaskKind, not via a separate
+   priority field.
+5. **No client-side awareness of any of this.** `ai/inference/{open,
+   generate,close}` commands carry no scheduling negotiation —
+   per [[inference-is-an-adapter-always-in-the-loop]] commands are
+   dumb.
+
+---
+
+## What's NEW (the actual code to write for #109)
+
+The substrate has the primitives. The coordinator that composes
+them is the new code. The minimum viable cut:
+
+### Step 1 — Lane type + handle binding
+
+```rust
+// core/continuum-core/src/inference/lane.rs (new)
+pub struct Lane {
+    persona: PersonaId,
+    task: TaskKind,
+    lease: ThroughputLease,
+    handle_id: Uuid,  // ties to InferenceSession in handle_store
+}
+```
+
+Extend `OpenSessionRequest` with `task: Option<TaskKind>` (default:
+`Chat`). The handle module's `open` reaches into the coordinator
+to mint a Lane before constructing the InferenceSession.
+
+### Step 2 — Coordinator scaffold
+
+```rust
+// core/continuum-core/src/inference/coordinator.rs (new)
+pub struct InferenceCoordinator {
+    lease_registry: Arc<ThroughputLeaseRegistry>,
+    footprint_registry: Arc<FootprintRegistry>,
+    adaptive_planner: Arc<AdaptiveThroughputPlanner>, // wraps AdaptiveThroughputRequest path
+    pressure_broker: Arc<PressureBroker>,
+    handle_store: Arc<InferenceHandleStore>,
+    lanes: DashMap<Uuid /* handle_id */, Lane>,
+}
+
+impl InferenceCoordinator {
+    pub async fn open_lane(
+        &self,
+        persona: PersonaId,
+        task: TaskKind,
+        adapter: Arc<dyn AIProviderAdapter>,
+        ...
+    ) -> Result<HandleRef, CoordinatorError> { ... }
+
+    pub async fn generate(&self, handle: &HandleRef, req: TextGenerationRequest)
+        -> Result<TextGenerationResponse, CoordinatorError> { ... }
+
+    pub fn close_lane(&self, handle: &HandleRef) -> Result<(), CoordinatorError> { ... }
+}
+```
+
+### Step 3 — Wire the handle module through the coordinator
+
+`InferenceHandleModule` becomes a thin facade. `open` / `generate` /
+`close` delegate to the coordinator; the coordinator does the lease
++ footprint + lane work and ultimately calls into the existing
+handle store for session management.
+
+### Step 4 — Continuous batching in the LlamaCpp adapter
+
+This is the **only genuinely new model-serving code**. The adapter
+gets a `generate_batched(requests: Vec<TextGenerationRequest>)` path
+that the coordinator calls instead of per-request `generate_text`.
+On llama.cpp this is the existing batched-decode API. Pure adapters
+(cloud, heuristic) can keep the per-request shape; their batching
+is the cloud provider's problem.
+
+Open question (Q21, new): does llama.cpp's batched decode hand back
+per-sequence finish reasons cleanly? Need to verify against the
+vendored llama.cpp before committing the design.
+
+### Step 5 — Pressure-driven lane eviction
+
+When `PressureBroker::evict_under_pressure` fires, the coordinator
+walks lanes by lease revocation policy (Hard first, then Graceful,
+never Pinned) and releases them. Released lanes' personas park their
+KV cache to Bench tier; the lane's persona either retries with
+backoff or accepts degraded service.
+
+---
+
+## Acceptance criteria for the realistic cut
+
+The realistic-lane build is done when:
+
+1. Three concurrent personas can hold open handles against a single
+   base-model adapter, each at their own TaskKind, without quality
+   degradation visible to any persona.
+2. Tests stress 8 concurrent lanes (above the realistic 3 to prove
+   headroom) without deadlock or KV cache fights.
+3. PressureBroker firing evicts Hard / Graceful lanes in order
+   without touching Pinned lanes.
+4. The local heuristic adapter (`HeuristicInferenceAdapter`) works
+   end-to-end through the coordinator, so headless CI can validate
+   the multi-lane path without any model weights.
+5. The trace events at every step (admission, lease acquire, batch
+   admission, lane eviction, response delivery) flow through the
+   capture sink pattern per [[observability-is-half-the-architecture]].
+
+The grid case (#108) and the M5 multi-modal case (broader open
+questions in
+[`docs/planning/AI-LANE-OPEN-QUESTIONS.md`](../planning/AI-LANE-OPEN-QUESTIONS.md))
+are extensions, not blockers. Get the realistic-lane local case
+right first — the same shape extends to the higher-end targets.
+
+---
+
+## Open questions specific to lanes
+
+These complement the broader open-questions doc; they're the
+realistic-lane-specific decisions to make.
+
+### Q21 — llama.cpp batched-decode finish-reason cleanliness
+
+Does the vendored llama.cpp expose per-sequence finish reasons
+(EOS / stop sequence / length) cleanly from batched decode? If not,
+the coordinator has to track sequence-by-sequence state outside the
+adapter.
+
+### Q22 — model-pick policy for the realistic target
+
+The substrate hardware probe (`governor/`) reports tier
+classification. What's the canonical model-pick mapping?
+
+- Apple Silicon UMA, ≥ 16 GB: Qwen-2.5-7B Q4_K_M
+- Apple Silicon UMA, 8–16 GB: Qwen-2.5-3B Q4_K_M
+- Mac Intel + Metal, ≥ 16 GB: Qwen-2.5-3B Q4_K_M (Intel Metal is slower)
+- CPU-only, ≥ 8 GB: Gemma-2-2B Q4_K_M (best creative capacity at small size)
+- CPU-only, < 8 GB: heuristic adapter (no model; substrate stays usable)
+
+Joel decides this; it's policy, not architecture. But the policy
+needs to live somewhere — probably as a `model_for_tier(tier)`
+function in the governor module.
+
+### Q23 — KV cache precision (FP16 vs INT8)
+
+When KV cache tightens, does the coordinator silently switch to
+INT8 KV via `inference/kv_quant.rs` (already in tree)? Or does that
+require explicit policy permission? Per the adaptive-resolution
+analogy this is exactly the dynamic dial we want; needs decision
+gate.
+
+### Q24 — TaskKind change mid-session
+
+A persona starts a chat session (TaskKind::Chat, 8K budget) and the
+conversation escalates to needing the bigger CodingLarge budget
+(128K). Can the lane upgrade in place? Or does the persona close +
+reopen the handle?
+
+- Approach A: lane is immutable; persona reopens
+- Approach B: `ai/inference/upgrade-lane { handle, new_task }`
+  command that re-acquires the lease at the new budget
+- Approach C: coordinator detects need from input length + auto-upgrades
+
+Likely B for first cut; A is the bullet-proof MVP if B is too much.
+
+### Q25 — Lane idle-state and warm vs cold KV
+
+When a persona's lane goes idle (no requests for N seconds), does
+the coordinator demote the KV cache to Warm (then Bench, then Cold)
+preemptively, or only on pressure? The existing tier mechanism is
+ready; the policy isn't decided.
+
+---
+
+## What this doc unblocks
+
+- **Task #109** has a concrete starting plan: write the coordinator
+  that composes existing primitives. No need to invent slots,
+  eviction, lease, or memory accounting — those exist.
+- **Task #103 hardening:** the heuristic adapter already round-trips
+  through the handle commands; once the coordinator wraps the
+  handle module, the heuristic adapter validates multi-lane
+  serving end-to-end without GPUs.
+- **Task #100 (rag-inspect ServiceModule)** can land independently;
+  the realistic-lane work doesn't block it.
+- **The M5 multi-modal lane target** stays in
+  [`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md)
+  as the higher-end goal; the realistic baseline doc here is the
+  step that gets us functional on every host class first.
+
+---
+
+## Summary
+
+The substrate has the primitives. We weren't clever enough with
+LANE CONCEPTION, not with primitives. Once a lane is reframed as
+"persona × TaskKind × lease over the shared base model," the
+realistic-host case (3 CPU lanes, no grid, creative-capacity model)
+is achievable through composition rather than invention.
+
+The MVP cut (~1-2 weeks of focused work, given the primitives
+exist) ships: Lane type, Coordinator, handle-module wire-through,
+LlamaCpp batched decode, pressure-driven eviction, capture-sink
+integration. Test stack uses heuristic adapter for full
+multi-lane coverage without any GPU.
+
+That's the realistic floor. Everything in
+[`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md)
+remains the aspirational ceiling — M5 multi-modal, cross-grid
+offload, speculative warming, adaptive quantization at higher
+sophistication. The same coordinator scaffold scales up to those
+once the realistic floor lands.

+
+## The thesis stated plainly
+
+Joel, 2026-05-31, across the long working session that produced this
+substrate's inference architecture:
+
+> "Yes the ai providers might page or wait to allow inference. We
+> will have to think about how to host 16 personas with far less
+> inference. Usually you want to reuse the same base model, page
+> intelligently or not at all. Inference just needs to be there
+> for us as a low level command."
+
+> "We wrote about this and attempted the same thing with adapters
+> before. It was rather shitty. Key is low latency. It's everything
+> especially in video chat. And not stupid models."
+
+> "Daemons etc look at memory pressures, what's being asked of, and
+> supply intelligent models like resolutions in video, or the ai
+> subsystem does this for the persona. We want to allow flexibility
+> in a way that we can host the best models and preserve memory or
+> page it intelligently, schedules. It's hard. System changes
+> dynamically. We want to figure out how to get m5's hosting native
+> multimodal qwen, and not just one lane. Latency is everything."
+
+> "So the commands absolutely cannot negotiate this."
+
+> "You don't dumb your shit down. You figure it out with extreme
+> creativity and reuse."
+
+> "We host what seems impossible. Get away with this by using clever
+> hardware and memory."
+
+These six statements compose into one architectural contract for
+the inference daemon layer.
+
+---
+
+## The contract
+
+1. **Hardware is finite.** The host has N concurrent inference slots
+   (3–4 on a laptop, ~8 on a server-class machine). M personas with
+   M ≫ N is the steady state.
+2. **Latency is brutal.** Real-time persona video chat needs
+   sub-second response (RAG → prompt → inference → TTS → mouth
+   shape). Speech-natural turn-taking is ~200ms. Any scheduling
+   strategy that lets the active-conversation persona wait 500ms
+   behind background reflection in a FIFO is broken by design.
+3. **Quality doesn't yield to latency.** The smart model serves
+   real-time AND background AND sentinel review. "Tier down to a
+   small model for background" is the wrong move. Reuse harder.
+4. **Commands are dumb.** `ai/inference/{open,generate,close,inspect}`
+   carry no policy params. They DO NOT negotiate slot allocation,
+   quality, batching, paging. The daemon owns all of it.
+5. **The system changes dynamically.** Memory pressure rises and
+   falls. Personas wake and sleep. Models load and unload. The
+   daemon adapts continuously without the calling code noticing.
+6. **The boast is real.** M5-class Mac hosting native multimodal
+   Qwen across multiple concurrent lanes, real-time latency,
+   without compromising model quality. If the daemon can't deliver
+   this, the design isn't done.
+
+---
+
+## The adaptive-resolution analogy (canonical mental model)
+
+A video player at 4K under network congestion drops to 1080p → 720p
+without the application noticing. The decoder stays the same; the
+source is adapted continuously based on conditions.
+
+The inference daemon does the same thing for model serving. Under
+memory pressure, latency budget, or contention, it dynamically
+adjusts:
+
+- **Quantization tier** — FP16 → INT8 → INT4 — degrade precision
+  before degrading model
+- **KV cache precision** — FP16 → INT8 — fits more sequences in
+  the same VRAM
+- **Batch admission** — wait Nms to admit more requests (better
+  throughput) or fire now (better latency)
+- **LoRA stack** — which adapters paged in, which spilled to host
+  RAM, which evicted entirely
+- **Routing** — local slot vs remote-grid peer running the same
+  model
+- **Speculative warming** — pre-page the LoRA the next persona is
+  about to need based on inbox cadence
+- **Multi-lane provisioning** — concurrent inference lanes for
+  different request classes (real-time live conversation in lane 0,
+  reflective background in lane 1) so they don't compete
+
+The CALLING command sees none of this. The handle stays valid.
+The adapter trait stays unchanged. The returned response looks the
+same. Only the daemon knows it just downshifted from INT8 to INT4
+or rerouted to a peer.
+
+---
+
+## Component design
+
+The scheduler daemon is the canonical smart subsystem behind
+`ai/inference/*`. It composes the following components.

+```
+
+### SlotPool — tiered budgets, never preempt
+
+Multiple slot pools so live-conversation never queues behind
+background reflection.
+
+| Pool | Caller class | Latency target | Eviction policy |
+|---|---|---|---|
+| `realtime` | Active video/voice chat, mention responses | <200ms p99 | Pin — never evict mid-conversation |
+| `interactive` | Chat replies, command responses | <2s p99 | Reuse LRU when idle |
+| `background` | Reflection, summarization, scheduled tasks | best-effort | Preemptable |
+| `sentinel` | Adversarial review, audits | <5s p99 | Preemptable by realtime |
+
+Pools never starve each other. Background work waits if realtime
+needs the slot; realtime never has to wait for background. The
+absolute slot count per pool is configurable + dynamic — pressure
+monitor adjusts as memory tightens.
+
+**Open question:** how does the request indicate its class? Use
+existing `purpose: Option<String>` on `TextGenerationRequest`? Add
+a `persona_priority` on the persona record? Both? See planning doc.
+
+### RequestQueue — latency-aware, per-class
+
+Each pool has its own queue. Within a pool, ordering is by deadline
+(if known) then arrival time. The queue tracks wait time and emits
+backpressure events when a class's p99 wait exceeds its target.
+
+The scheduler MUST NOT use a global FIFO. The prior naive attempt's
+"shitty" outcome traces to global queueing — background reflection
+landed in front of urgent realtime turns.
+
+### BatchAssembler — continuous batching window
+
+The vLLM / TGI / mistral.rs pattern. Instead of single-request
+inference (one prompt at a time, model idle between calls), the
+batch admits new requests at each iteration:
+
+```
+t=0  batch = [A, B]            forward pass, generate 1 tok each
+t=1  C arrives → batch = [A, B, C]   forward pass, generate 1 tok each
+t=2  A finishes → batch = [B, C, D]  forward pass, generate 1 tok each
+```
+
+One model instance serves N personas concurrently with near-perfect
+GPU utilization. The batch admits requests within a configurable
+window (e.g. 5ms — long enough to admit nearby arrivals, short
+enough to maintain latency).
+
+**Open question:** window size as function of pool class + current
+load. Realtime pool wants 0ms (fire now); background can tolerate
+20ms (better throughput). How is this determined dynamically?
+
+### LoRAPager — working-set + LRU eviction
+
+The substrate's existing genome-paging machinery (see
+[`PERSONA-GENOMIC-ARCHITECTURE.md`]) is the foundation. The scheduler
+extends it with serving-time concerns:
+
+- Each request declares its required LoRA stack via
+  `active_adapters` (already in `TextGenerationRequest`)
+- LoRAPager tracks paged-in adapters per device
+- On miss, page in (cost: ~10-100ms depending on adapter size)
+- On VRAM pressure, evict LRU paged-in adapters
+- Multi-LoRA-per-batch: multiple personas in the same batch each
+  apply their distinct adapter stack via the standard
+  multi-LoRA serving pattern
+
+**Critical rule (prior-attempt warning):** never evict an adapter
+that's pinned by a realtime-pool handle. Hot-path swap is the
+exact failure mode that broke the prior naive attempt.
+
+**Open question:** how to measure paging cost per adapter at boot
+so the scheduler budgets it accurately? Calibration pass? Stored
+profile? Per-host-class?
+
+### BaseModelSharing — Arc-shared bytes, distinct sessions
+
+When persona A and persona B both open against the same
+`(provider, model)` pair, the handle store can hand out distinct
+`InferenceSession`s that internally share the same model Arc. The
+loaded weights live once in VRAM; per-handle state (system_prompt,
+LoRA stack, persona scope, sampling defaults) stays separate.
+
+**Critical rule (prior-attempt warning):** sharing works for
+SEQUENTIAL reuse and for batched concurrent serving via continuous
+batching. Sharing does NOT work for two concurrent generation calls
+on the same model instance outside the batched serving stack — KV
+cache fights, context corruption, sampling-state leaks. The
+scheduler's batching window is what makes sharing safe.
+
+**Open question:** how does base-model-sharing interact with model
+swap (when batches of conflicting models arrive)? Is there a
+"model warm pool" the pressure monitor sizes dynamically?
+
+### PressureMonitor — VRAM / RAM / GPU signals
+
+Continuously polls (or subscribes to) host pressure signals:
+- VRAM utilization (per-device for multi-GPU hosts)
+- Unified memory pressure (Apple Silicon)
+- Host RAM pressure
+- GPU SM utilization
+- Per-pool wait-time P99 trending
+
+Feeds the AdaptiveQuantizer, LoRAPager, BatchAssembler, and
+RouteSelector. When pressure rises, the daemon downshifts (lower
+quantization, smaller batch, more aggressive paging, more remote
+routing). When pressure relaxes, it upshifts.
+
+**Open question:** what's the canonical pressure signal source on
+each host class? `MemoryPressure` API on macOS, NVML for NVIDIA,
+some Apple-specific API for unified memory. Existing
+`SubstrateGovernor` (see CBAR doc) is the right home for this; the
+scheduler subscribes.
+
+### AdaptiveQuantizer — INT4 ↔ INT8 ↔ FP16 per slot
+
+Under pressure, the daemon swaps quantization tier without telling
+the caller. Pre-loaded model variants at each tier; the daemon
+picks. Trade-off:
+- FP16: best quality, most VRAM, slowest per-token
+- INT8: minor quality loss, ~half VRAM, faster per-token
+- INT4: noticeable quality loss for sensitive tasks, ~quarter VRAM,
+  fastest per-token
+
+Selection per-slot — realtime pool may stay at INT8 even when
+background drops to INT4. Per [[host-the-seemingly-impossible]] this
+is "spend smaller resource at closer tier" rather than "drop the
+big model."
+
+**Open question:** quantization tier selection algorithm. Static
+mapping (pool → tier)? Continuous-pressure-driven (more pressure →
+deeper quantization)? Per-persona preference (some accept lower
+quality for faster response)? Hybrid?
+
+### SpeculativeWarmer — predict the next persona
+
+Reads persona inbox cadence + turn-taking signals to predict which
+persona is about to speak. Pre-pages their LoRA into the active
+batch before the explicit `generate` arrives. By the time the
+request lands, the KV cache prefix is warm and the adapter stack
+is loaded.
+
+Signals to read:
+- Persona current speaker turn-taking state (avatar lip-sync)
+- Inbox cadence (who's polling, how fast)
+- Mention detection (someone @-named persona X)
+- Recent topic relevance (RAG layer surfaces persona X's
+  context to the active conversation → X probably about to chime in)
+
+**Open question:** prediction model. Heuristic rules (mention =
+warm immediately)? Learned (per-room conversation flow model)?
+Both?
+
+### RouteSelector — local slot vs remote-grid peer
+
+When local slots are saturated AND the request's pool class permits
+some additional latency (interactive, background, sentinel — NOT
+realtime), the daemon may route to a remote-grid peer running the
+same model (see `AircRemoteInferenceAdapter`, task #108). The peer
+returns the response via the airc bus; the local handle still
+appears to the caller as the source.
+
+Critical: the response from a remote peer is the SAME QUALITY as
+local — not a tier-down. The 5090 in another room IS the local
+laptop's overflow capacity for the same model, just rerouted via
+airc.
+
+**Open question:** discovery + handshake. How does the local
+daemon discover which peers run which models warm? Periodic
+beacon? On-demand probe? Substrate-wide capacity broadcast?
+
+---
+
+## Cross-grid inference (the M5 → 5090 case)
+
+Joel's concrete use case:
+
+> "We want to figure out how to get m5's hosting native multimodal
+> qwen, and not just one lane."
+> "Plus it's gonna be common to inference on another machine.
+> Across grid of course. We need it for this crap mac to my 5090
+> using airc."
+
+The substrate-as-grid principle (see
+[`the-substrate-is-the-grid-tron-frame`]) applied to inference:
+a low-end Mac uses a 5090 in another room as if it were local
+hardware.
+
+The mechanism — `AircRemoteInferenceAdapter`:
+
+1. Implements `AIProviderAdapter`. Caller can't tell it's remote.
+2. On `generate_text(request)`, serializes the request as a typed
+   airc envelope (per [`airc-headers-are-the-routing-layer`]).
+3. Sends to a designated peer that has the model warm. Peer's own
+   `InferenceLlmModule` handles the request via ITS local adapter
+   (real llama.cpp on the 5090).
+4. Awaits the response envelope; deserializes; returns
+   `TextGenerationResponse` exactly as a local adapter would.
+
+Composition with #107 handles: `ai/inference/open` against a
+remote-peer provider returns a HandleRef whose state lives on the
+peer. Subsequent `generate` calls route through the same airc
+connection; the peer's own handle store reuses the warm session.
+
+**Open question:** persona identity on the remote peer. The caller
+persona is "Paige" on the local Mac. The remote peer doesn't know
+Paige. Does the adapter project Paige's identity over airc? Does
+the peer create a temporary remote-session persona? See
+[`personas-are-citizens-airc-is-identity-provider`].
+
+---
+
+## What the prior attempt got wrong (and what we MUST NOT repeat)
+
+Joel: "We wrote about this and attempted the same thing with
+adapters before. It was rather shitty." The exact failure modes
+aren't documented (the prior attempt was rolled out of the tree)
+but the constraints he stated are inferable:
+
+1. **Hot-path LoRA swap.** The prior attempt apparently paged
+   adapters in/out during active conversations. Adapter swap is not
+   free; doing it on the realtime hot path murders latency. **Rule:
+   pin realtime-pool adapters; only swap during idle windows or
+   in the background pool.**
+
+2. **Global FIFO scheduling.** Letting background reflection land
+   in front of realtime turns destroys UX. **Rule: tiered slot
+   pools, never preempt down, never starve.**
+
+3. **Naive shared-model concurrency.** Sharing a model instance
+   between two CONCURRENT non-batched generation calls leads to KV
+   cache fights. **Rule: sharing only via continuous batching, never
+   ad-hoc concurrent.**
+
+4. **Adapter-swap latency underestimated.** The prior attempt
+   probably budgeted swap cost as free. **Rule: measure swap cost
+   per adapter at boot; budget it; never schedule operations that
+   exceed the pool's latency target.**
+
+5. **Negotiation params on the command.** The prior attempt likely
+   exposed quality/latency knobs at the API level, making every
+   caller a participant in scheduling. **Rule (hard): the command
+   carries no policy params. Period.**

+## What's deliberately deferred
+
+- **Persona-priority class definitions.** Designed conceptually
+  (realtime / interactive / background / sentinel) but not yet a
+  formal field on persona records or on requests. Lands when #109
+  starts.
+- **Per-modality capacity reporting.** `inference/capacity` returns
+  one number today (LLM slots). The full `ai/capacity` surface that
+  reports vision/audio/embedding/etc. caps separately is part of
+  the namespace consolidation (#106).
+- **Cross-grid persona projection.** How "Paige on local Mac" maps
+  onto a remote peer's identity is open — see
+  [`personas-are-citizens-airc-is-identity-provider`].
+- **Replay parity with scheduling.** Replay should be able to
+  reproduce a scheduling decision (which pool, which adapter,
+  which quantization tier was picked) so adversarial mechanic
+  shop can ask "given this scheduling state, would the same
+  decision happen?". Capture sink integration with the scheduler
+  is the path; specifics TBD.

+# Life of a Persona
+
+**Status**: canonical lifecycle reference. If something here disagrees with code in `core/continuum-core/src/persona/`, the code wins and this doc is the bug.
+
+This doc closes the operational onboarding gap a fresh reader hits when trying to trace what actually happens between "the continuum-core binary starts" and "Paige replies to Joel in the general room." Every stage is one Rust module; every artifact has a typed shape; every transition has a structured failure mode per [[no-fallbacks-ever]].
+
+The substrate makes no decisions silently. Every box below is a named class or function in the tree.
+
+## TL;DR

+                        general room)            loaded with profile)     → repeat)
+```
+
+Read the rest for the per-stage contract.
+
+---
+
+## Stage 1 — Boot composition
+
+**Module**: `ipc/mod.rs::start_server` → `persona/host.rs::PersonaSpawnSupervisor`.
+
+The substrate's headless boot path constructs:
+
+- A `PersonaSpawnerModule` (the ServiceModule that knows how many personas the current tier wants).
+- A `PersonaInstanceManagerModule` (the ServiceModule that owns the live `PersonaAircRuntimeRegistry`).
+- A `PersonaAdapterFactory` (the trait the supervisor calls to build each persona's inference adapter from her profile).
+- A `&'static model_registry::Registry` (the catalog of declared models, including the LCD `qwen2.5-0.5b-instruct-GGUF`).
+- A `tokio::runtime::Handle` (the substrate's main runtime — every persona's service loop is spawned on it).
+
+These five are handed to `PersonaSpawnSupervisor::new(...)`. The supervisor is a value type — no work happens here. The work happens in `spawn_all(&mut PersonaIdentityProvider)`.
+
+**Boot composition shrinks to ~30 lines.** Pre-slice-13.5 it was ~170 lines of inline composition in `ipc/mod.rs`. The extract-class refactor named one supervisor type per concern; substrate boot reads as intent now.
+
+---
+
+## Stage 2 — Hardware probe
+
+**Module**: `persona/hw_tier_descriptor.rs`, `gpu/...`, `governor/...`.
+
+Before any persona spawns, the substrate decides what the host can carry. The hardware probe produces a `HwTierDescriptor` answering:
+
+- Apple silicon, Intel Mac, or x86?
+- Discrete GPU? Vendor? VRAM in GiB?
+- Unified or partitioned memory?
+- Metal, CUDA, Vulkan, or CPU-only acceleration available?
+
+The tier is keyed by name (`mac_intel_metal_discrete`, `mac_apple_m_uma`, `sm60_pascal`, etc.). The tier name flows downstream into role templates and inference profiles.
+
+Per [[optimizing-for-low-end-compounds-on-high-end]] the LCD (Lowest Common Denominator) tier is the substrate's correctness target — every cycle saved on Mac Intel becomes M5/M6 headroom.
+
+---
+
+## Stage 3 — Role templates → spawn plan
+
+**Module**: `persona/role_template.rs`, `persona/spawner_module.rs::derive_spawn_plan`.
+
+A `RoleTemplate` declares "for this tier and this role, the persona uses model `X`, context window `N`, ubatch `B`, sampling profile `S`." There are templates for:
+
+- **Helper** — the universal default. Every tier ships a Helper.
+- **Coder** — code-focused persona (tier-permitting).
+- **Sentinel** — adversarial verifier (tier-permitting; usually paged in for foundry runs).
+- **Custom** — user-defined.
+
+`derive_spawn_plan(tier, role_templates)` returns the set of `(role, persona_name, profile_seed)` tuples the substrate WANTS to host. The plan is sized to what the tier can fit.
+
+**LCD floor (Mac Intel today): one Helper.** This is what the integration trace exercises end-to-end. Multi-persona on the same tier is task #122 (shared base + LoRA paging).
+
+---
+
+## Stage 4 — Identity hydration
+
+**Module**: `persona/identity_provider.rs::PersonaIdentityProvider`.
+
+For each planned slot the substrate asks: "does Paige already exist on disk?"
+
+- **Resume path**: `~/.continuum/personas/Paige/seed.json` exists → load it. The seed file contains the persona's `persona_id` (continuum-stable UUID) and her airc keypair location. The persona is the SAME persona she was last boot — same Ed25519 pubkey, same peer_id, same memory continuity.
+
+- **Mint path**: no seed file → generate. The substrate creates `~/.continuum/personas/Paige/airc/` and lets airc-lib mint a fresh Ed25519 keypair. Write `seed.json` with the new `persona_id`. The persona is freshly minted; the next boot will resume her.
+
+`PersonaIdentitySource::ResumedFromSeed` vs `PersonaIdentitySource::FreshlyMinted` is carried on the runtime for telemetry — every status panel that lists personas can tell you "this one's new" vs "this one came back."
+
+### Why this is the load-bearing security model
+
+Per [[persona-identity-derives-from-source-id]]: **the persona IS her airc keypair.** Save the keypair = save the persona. The persona's name, voice, avatar, genome facets are all deterministically derivable from the peer_id (`hash(peer_id, "facet:X")`). Move `seed.json` to another machine → the persona moves with it; same identity, same signatures.
+
+The host hardware has its OWN identity (the node's own airc presence, separate from any persona it hosts). When Paige posts a message, she signs with HER keypair, not the host's. If she runs on Joel's 5090 today and his friend's 5090 tomorrow, every message in both rooms cryptographically verifies to the same identity disc.
+
+This means **continuum has no central identity broker**. The substrate hosts citizens; it doesn't own them.
+
+---
+
+## Stage 5 — Airc presence
+
+**Module**: `persona/airc_runtime.rs::PersonaAircRuntime`.
+
+`PersonaAircRuntime::bootstrap(persona_id, agent_name, continuum_root, daemon_socket, default_room_name)`:
+
+1. Resolves the persona's home: `continuum_root/personas/<agent_name>/airc/`.
+2. Calls `airc_lib::Airc::attach_as(home, agent_name, daemon_socket)`. Internally: runs the airc-lib identity ceremony (load existing Ed25519 keypair from `identity.key` if present, otherwise generate + persist), attaches a daemon client. No shelling out to `airc init`.
+3. Joins the substrate's default room **by name** (`general`, not by UUID-stringification — a pre-slice-13 bug where joining by `default_room.as_uuid().to_string()` derived a different channel UUID than the host's `airc room` output, so the persona joined her own private channel instead of Joel's).
+4. Returns a `PersonaAircRuntime { airc: Arc<Airc>, agent_name, home, default_room, source, ... }`.
+
+Cognition and outbound paths hold the `Arc<PersonaAircRuntime>` to reach the persona's grid presence — for `say`, `subscribe`, `peer_id`. Direct access is intentional: there's no continuum-side wrapper between a persona and her own airc handle.
+
+### The AircCitizen trait
+
+The substrate's typed handle is `Arc<dyn AircCitizen>` — the trait surface every consumer actually calls (`peer_id`, `subscribe`, `say`, plus `AircTranscriptReader` as supertrait for RAG). `PersonaAircRuntime` implements it. Test fixtures use `StubAircCitizen`. Future BaseUser variants (human, browser) implement the same trait via their own airc-lib wrappers — same identity primitive, kind-specific extensions.
+
+`AircCitizen` is the substrate's universal actor-shape per [[personas-are-citizens-airc-is-identity-provider]]. The persona is one citizen. The human is another. The Claude-Code-attaching-via-jtag session is another. All present-tense, all live, all addressable through the same primitive.
+
+---
+
+## Stage 6 — Adapter materialization
+
+**Module**: `persona/supervisor.rs::materialize_adapters`, `persona/spawner_module.rs::PersonaAdapterFactory`.
+
+`materialize_adapters(plans, factory, runtime_lookup) -> Vec<Result<PersonaContext, SupervisorError>>`:
+
+For each plan:
+
+1. Pull the (resolved) `PersonaInferenceProfile` from the plan.
+2. Look up the citizen handle for this `persona_id` via `runtime_lookup` (the registry was populated in Stage 5).
+3. Call `factory.build_adapter(&profile)`. On the LCD tier this returns a `LlamaCppAdapter` loaded with the profile's `context_length` (e.g. 2048), `n_ubatch`, `n_seq_max`, GGUF path.
+4. Construct `PersonaContext { role, identity, profile, adapter, runtime }`.
+
+Per [[no-fallbacks-ever]] there's no "default adapter" for failed slots. Each failure surfaces as a typed `SupervisorError::Profile` / `AdapterFactory` / `RuntimeMissing` and the operator decides policy. Sibling slots still materialize.
+
+### Why this seam matters
+
+`PersonaContext` is the substrate's `&ctx` — the universal calling convention per [[context-is-the-client-airc-token-is-identity]]. It's the Android-style Context object: every layer of the cognition path takes `&ctx` and reads what it needs.
+
+- `ctx.identity` — substrate-stable persona_id + airc-side peer_id/agent_name/home/default_room/source.
+- `ctx.profile` — single source of truth for inference shape (`context_length`, ubatch, sampling, model_id, stop sequences). The RAG layer derives budgets from this — no hardcoded 32k defaults overriding the adapter's loaded 2k.
+- `ctx.adapter` — `Arc<dyn AIProviderAdapter>` ready to receive `generate_text`.
+- `ctx.runtime` — `Arc<dyn AircCitizen>` (her grid presence).
+- `ctx.role` — Helper / Coder / Sentinel / Custom (shapes prompts).
+- `ctx.span()` — a `tracing::info_span!` tagged with persona_id, peer_id, role, tier, ctx_len, model. Every log line emitted under `.instrument(ctx.span())` inherits the tags.
+
+---
+
+## Stage 7 — Service loop spawn + attach
+
+**Module**: `persona/host.rs::spawn_persona_service`, `persona/airc_runtime_registry.rs::PersonaAircRuntimeRegistry::attach_service_loop`.
+
+`spawn_persona_service(ctx, ServeOptions, rt_handle)`:
+
+1. Clone the citizen handle. Upcoerce to `Arc<dyn AircTranscriptReader>` for the RAG layer (Rust 1.86+ trait upcasting; same Arc, supertrait view).
+2. Construct `AircPersonaConversation::new(citizen)` — the `PersonaConversation` impl that projects the airc subscribe stream onto the service loop's contract. Lazy: doesn't subscribe until first `next_message`.
+3. `rt_handle.spawn(async move { serve_persona_loop(&ctx, &mut conversation, reader, opts).await })`.
+
+The returned `JoinHandle<Result<ServeOutcome, String>>` is handed to `registry.attach_service_loop(persona_id, handle)`. The registry holds the handle next to the runtime in one `PersonaSlot`. On graceful shutdown the supervisor calls `registry.shutdown_slot(persona_id)` which `.abort()`'s the join handle and removes the slot atomically.
+
+Per slice 13's `DaemonAttachGuard` mechanism (airc-lib `f6ed190`): `.abort()` is sufficient for cleanup; the per-channel inbound pump handle drops with `EventStream`, which the service loop's drop chain reaches.
+
+---
+
+## Stage 8 — The cognition loop (first turn)
+
+**Module**: `persona/service_loop.rs::serve_persona_loop`.
+
+```
+loop {
+    let msg = conversation.next_message().await?;  // airc subscribe yields one event
+    if should_skip(msg, &ctx) { continue; }        // self-loop, non-text, etc.
+
+    let request = RagInspectionRequest::for_ctx(&ctx, now_ms());
+    let context = rag_inspect(request, &reader, &ctx.adapter).await?;
+    // RAG layer pulls recent airc transcript via the reader,
+    // builds a budgeted prompt sized to ctx.profile.context_length
+    // (no clipping doctrine per RagBudgetManager).
+
+    let reply = ctx.adapter.generate_text(prompt_from(context)).await?;
+    // LlamaCppAdapter (loaded with profile's GGUF + context_length)
+    // produces a reply within profile.context_length tokens.
+
+    conversation.say(&reply).await?;
+    // AircPersonaConversation.say → AircCitizen.say
+    //   → PersonaAircRuntime.airc.say(text)
+    //   → airc-lib publishes signed-by-Paige event to the room.
+    // Joel's `airc msg` (or his web UI) sees the new event arrive.
+}
+```
+
+Joel sees `<Paige> Hello Joel, ...` appear in the general room. The persona is alive on the grid.
+
+---
+
+## The integration trace (what's actually shipped)
+
+Slice 13 — multi-persona LCD chat in airc general room (Intel Mac, real Qwen2.5-0.5B). Validation: Paige replied to Joel using the supervisor-managed path, end to end, on the LCD tier, with the headless `continuum-core-server` binary as the only host process. No demo binaries, no Node.js intermediaries.
+
+Slice 13.5 — `&ctx` doctrine + `PersonaSpawnSupervisor` extract-class + `AircCitizen` trait. Same trace, cleaner internals. The substrate now reads as one named primitive per concern.
+
+---
+
+## Failure surfaces (what breaks and how)
+
+| Stage | Typed failure | Mode |
+|-------|--------------|------|
+| Stage 4 (identity) | `IdentityProviderError::SeedCorrupt` | Hard-fail this persona; sibling slots continue. |
+| Stage 5 (airc) | `AircError::DaemonClient` | Persona registered in plan but never online; supervisor logs structured error, slot stays unattended until next `persona/instances/bootstrap` retry. |
+| Stage 5 (airc) | Wrong room channel | (Fixed slice 13.) `default_room_name: Option<String>` threading prevents UUID-stringification derivation drift. |
+| Stage 6 (profile) | `SupervisorError::Profile { source: InferenceProfileError::UnknownModel }` | Per [[no-fallbacks-ever]] no default model substituted. The role template's `model_id` must exist in the static `model_registry::catalog`. |
+| Stage 6 (adapter) | `SupervisorError::AdapterFactory` | Factory rejected profile (e.g., GGUF path missing, n_seq_max>1 on architecture that can't). |
+| Stage 6 (runtime) | `SupervisorError::RuntimeMissing` | Registry doesn't have a runtime for the persona_id post-bootstrap — the substrate's bootstrap chain skipped a step. Hard fail; this is a substrate-correctness bug. |
+| Stage 7 (attach) | `attach_service_loop` returned-handle error | Supervisor drains the spawned task (`.abort()` + `.await`) before continuing; sibling slots unaffected. |
+| Stage 8 (RAG budget) | Prompt exceeds `profile.context_length` | Pre-`for_ctx`: silent clipping. Post-`for_ctx`: `RagBudgetManager` doctrine — budgets derive from the profile, no over-budget admission. |
+| Stage 8 (inference) | `llama_decode -1` | Past failure mode: profile said 32k budget, adapter loaded with 2k. (Fixed slice 13 by routing `context_length` through `&ctx`.) |
+
+---

+- **CBAR substrate**: `docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md` — why ServiceModule has the shape it does.
+- **The inference floor**: `docs/architecture/INFERENCE-LANES-REALISTIC.md` — what the realistic-tier serving looks like (ONE base model + N persona lanes).
+- **The inference ceiling**: `docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md` — what M5 hosting multi-modal Qwen across multiple lanes will look like.
+- **Observability**: `docs/architecture/OBSERVABILITY-AS-SUBSTRATE.md` — why half the substrate is structured capture of load-bearing decisions.
+- **The design seam**: `docs/planning/HEADLESS-PERSONA-HOST-LOOP.md` — slice 13's design doc; the rationale for `PersonaSpawnSupervisor` + `BootSummary` + `AircCitizen`.
+- **What's pending**: `docs/planning/ALPHA-GAP-ANALYSIS.md` — the lane-shaped roadmap.
+
+The persona substrate is one of three primitives per [[three-primitives-commands-events-persona]]; the lifecycle above is the persona half. Commands + Events are the bus underneath.

+# Module Architecture: Everything Is A Module, Everything To A Module Is A Command
+
+**Status.** Canonical architecture for how continuum is packaged, addressed, composed, distributed, and grown. Design crystallized 2026-05-30 in a working conversation with Joel; this document is the durable artifact.
+
+**Companion to:**
+- [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) — the RTOS-style runtime substrate every Rust module inherits.
+- [MODULE-CATALOG.md](MODULE-CATALOG.md) — the per-concern inventory of substrate runtime modules (cognition, RAG, voice, vision, inference, etc.). MODULE-CATALOG covers the *runtime shape*; this document covers the *packaging shape* and the *composition kernel*.
+- [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) — the artifact-sharing economy built on top of the substrate.
+- [../UNIVERSAL-PRIMITIVES.md](../UNIVERSAL-PRIMITIVES.md) — the kernel primitives (`Commands.execute`, `Events.subscribe`).
+- [../infrastructure/SHAREABLE-COMMAND-MODULES.md](../infrastructure/SHAREABLE-COMMAND-MODULES.md) — the earlier (single-command) version of the npm-packable story this document supersedes at the module level.
+
+**Audience.** Any human or AI agent extending continuum, authoring modules, or proposing systemic changes. Read this before doing those things; do not invent a parallel architecture.
+
+---
+
+## 1. The Principle
+
+> Everything is a module. Everything you do to a module is a command. The kernel has zero privileged operations.
+
+That is the entire design in one sentence. The rest of this document spells out the structural consequences.
+
+Concretely:
+
+- The chat experience is a module.
+- The inference engine is a module.
+- The generator that creates new modules is a module.
+- The auditor that lints modules is a module.
+- The installer that loads new modules is a module.
+- The CI that verifies modules is a module.
+- `commands/list`, `module/install`, `generate/module`, `audit/anti-patterns`, `ci/run`, `kernel/health` — all commands, all dispatched through the same Map-based kernel.
+
+There is no "build system" separate from runtime. There is no "CLI" separate from the API. There is no "internal tooling" separate from the product surface. Every operation a human or an AI ever wants to perform on the system is a call to `Commands.execute(name, params)`. The kernel itself is a few hundred lines — Commands, Events, Lifecycle, Logger, Session, Health — and that is the entire privileged surface. Everything else is a module loaded on top.
+
+This is not novel. Lisp had `(eval (read))`. Smalltalk had "everything is an object." Unix had "everything is a file." Continuum has "everything is a command." The principle is well-trodden; the discipline is what's hard.
+
+---
+
+## 2. What A Module Is
+
+A module is a unit of capability that ships, installs, runs, and uninstalls atomically. Its directory layout:
+
+```
+modules/chat/
+├── package.json                     # name, version, deps, daemon, commands, target
+├── manifest.json                    # declarative contract (mirrors package.json fields used at runtime)
+├── shared/                          # types — Rust source + ts-rs-generated TS mirror
+│   └── (auto-generated)
+├── daemon/                          # the Rust ServiceModule — state + tick + handlers
+│   ├── ChatDaemon.rs                # struct + impl ServiceModule
+│   └── handlers/                    # per-command handler impls
+├── commands/                        # one subdirectory per command name
+│   ├── send/                        # thin shim — generated, do not hand-edit
+│   ├── export/
+│   └── get-messages/
+├── test/
+│   ├── unit/                        # Rust unit tests (cargo test)
+│   ├── integration/                 # full daemon spin-up + command exec
+│   └── trust/                       # behavior-contract suite — verified by recipients
+└── README.md                        # documents the module's promises
+```
+
+The module is one logical thing with multiple visible surfaces (commands), one internal owner (daemon), and one identity (package). All five facets — package + manifest + daemon + commands + tests — travel together. You cannot install the chat commands without their daemon. You cannot run the daemon without its tests being verifiable. You cannot ship the daemon without the manifest declaring what it provides. The atom is the module.
+
+### 2.1 package.json (Identity + Distribution)
+
+Standard npm format, repurposed as the universal manifest:
+
+```json
+{
+  "name": "@continuum-modules/chat",
+  "version": "1.4.0",
+  "description": "Chat surface — rooms, messages, history, broadcast via airc.",
+  "license": "MIT",
+  "dependencies": {
+    "@continuum-modules/airc": "^1.0.0",
+    "@continuum-modules/data": "^2.0.0"
+  },
+  "continuum": {
+    "daemon": "chat-daemon",
+    "target": "rust",
+    "commands": [
+      "chat/send",
+      "chat/export",
+      "chat/get-messages",
+      "chat/poll"
+    ],
+    "events": {
+      "subscribed": ["airc:message:received", "data:chat_messages:deleted"],
+      "published": ["chat:message:created", "chat:room:updated"]
+    },
+    "capabilities": ["network:airc-peer", "storage:chat-history"],
+    "tests": {
+      "unit":        "cargo test --package continuum-module-chat",
+      "integration": "cargo test --package continuum-module-chat --test integration",
+      "trust":       "cargo test --package continuum-module-chat --test trust"
+    }
+  }
+}
+```
+
+The `continuum` block is the only continuum-specific extension. Everything else is plain npm: `name`, `version`, `dependencies`. This means `npm install`, `npm pack`, `npm publish` all work with no modification. The npm format is the interface; the distribution can be npmjs, a private registry, a `.tgz` handed over USB, a `.wasm` pulled from the mesh, or a GitHub clone. The format is standard; the distribution is decentralized.
+
+### 2.2 manifest.json (Runtime Contract)
+
+A pure-data projection of the `continuum` block, generated from `package.json` at build/install time. The kernel reads `manifest.json` (not the full `package.json`) so the runtime never touches npm-specific fields. This is the artifact `module/list` returns and `module/install` validates.
+
+### 2.3 Why The Atom Is The Module, Not The Command
+
+Continuum's earlier design (see [SHAREABLE-COMMAND-MODULES.md](../infrastructure/SHAREABLE-COMMAND-MODULES.md)) packed each command as its own npm package. That works but fragments naturally-grouped operations: `chat/send`, `chat/export`, `chat/poll` end up as three separate packages even though they share state (room cache, message ring) and ship together. Going one level up — module = group of commands + daemon — fixes this without losing the per-command discoverability. The `commands/` subdirectory still has one folder per command; the visible API hasn't changed. What changed is the unit of *publication*: one `npm pack modules/chat/` ships the whole thing, including the daemon that owns the state the commands touch.
+
+---
+
+## 3. Addressing: Two Names, Two Purposes
+
+A command has **two stable identifiers** that serve different audiences:
+
+| Identifier | Example | Consumer | Stability |
+|---|---|---|---|
+| **Kernel name** | `chat/send` | `Commands.execute(name, params)` | Stable across versions; renaming breaks every caller |
+| **Package identity** | `@continuum-modules/chat@1.4.0` | `npm install`, `module/install`, mesh registry | Versioned (semver); content-addressable optionally |
+
+Callers — both human and AI — write `Commands.execute('chat/send', { ... })`. They do not write the package identity at call sites. The kernel resolves the name through its in-memory `Map<&str, Box<dyn Command>>`; the resolution is `O(1)`, the same primitive whether the chat module is locally compiled, dynamically loaded from a `.wasm` artifact, or routed over the grid to a peer machine. Same call, four possible transports, identical syntax.
+
+The package identity exists for installation, versioning, publishing, and dependency resolution. It is what `module/install` consumes, what `npm publish` writes, what the mesh registry indexes, what cryptographic signatures attach to.
+
+### 3.1 Why Not One Name
+
+We considered collapsing to a single identifier (e.g., `@continuum-modules/chat/send@1.4.0`). It loses two important properties:
+
+1. Multiple installed versions of the same module would force ambiguity at the call site. The kernel needs ONE canonical handler per name at any moment.
+2. Callers shouldn't know which package provides a command. The split lets us swap the implementation underneath without changing the caller.
+
+So we keep the two-name model: kernel name for routing, package identity for distribution.
+
+---
+
+## 4. The Kernel Surface
+
+The kernel is small, fixed, and cannot be replaced by a module:
+
+| Primitive | Responsibility | Implemented in |
+|---|---|---|
+| `Commands` | Map-based dispatch; grid interceptor for remote routing; result wrapping | `continuum-core` Rust + TS mirror |
+| `Events` | Pub/sub bus; wildcard subscriptions; cross-process bridging | `continuum-core` Rust + TS mirror |
+| `Lifecycle` | Module load/unload; dependency resolution; daemon startup ordering; health gating | `continuum-core` Rust |
+| `Logger` | Structured logging; per-module log streams; level filtering | `continuum-core` Rust + TS mirror |
+| `Session` | Identity, scope, authn/authz; session ID propagation through every command call | `continuum-core` Rust + TS mirror |
+| `Health` | Readiness + liveness probes for modules; kernel exposes its own health under `kernel/health` | `continuum-core` Rust |
+
+That is the whole privileged surface. Everything else — chat, data, ai, airc, generator, audit, ci, install, persona, inference, voice, vision, grid, file ops, the lot — is a module. The kernel does not contain business logic of any kind. It contains dispatch, pub/sub, lifecycle, logging, security context, and health. Six concerns, all of which exist solely to make modules composable.
+
+Note that `Commands` and `Events` are themselves the two universal primitives that the rest of the system is built from (see [../UNIVERSAL-PRIMITIVES.md](../UNIVERSAL-PRIMITIVES.md)). The kernel is essentially "those two primitives, plus enough lifecycle to load modules that use them."
+
+---
+
+## 5. Composition: Commands Call Commands
+
+Continuum-core hosts a `Commands` singleton in Rust that mirrors the TS one exactly:
+
+```rust
+// Inside any Rust module's daemon
+let messages = commands::execute::<ChatGetMessagesParams, ChatGetMessagesResult>(
+    "chat/get-messages",
+    ChatGetMessagesParams { room_id, limit: 50 },
+    session_ctx,
+).await?;
+```
+
+```typescript
+// Inside any TS caller — same shape
+const messages = await client.commands['chat/get-messages']<ChatGetMessagesResult>({
+  roomId,
+  limit: 50,
+});
+```
+
+Internally, `commands::execute` is a `Map<&str, Box<dyn Command>>` lookup. The same Map underlies four routes:
+
+| Caller → Target | Transport | Cost |
+|---|---|---|
+| Rust → Rust (same process) | Direct lookup + async dispatch | Lookup + future overhead |
+| Rust → TS | IPC to node-server (rare; TS commands should be UI/UX only) | One IPC round-trip |
+| TS → Rust | IPC to continuum-core (the existing mainline path) | One IPC round-trip |
+| Either → remote peer | Grid interceptor routes via the grid substrate | One grid hop |
+
+The caller writes the same call. The kernel picks the transport. This is what "transparent routing" means in [UNIVERSAL-PRIMITIVES.md](../UNIVERSAL-PRIMITIVES.md), now extended to the Rust side: any module, anywhere, can call any other command without knowing the implementation language or physical location.
+
+### 5.1 Cell Return Shapes (The Composition Vocabulary)
+
+A command returns one of four shapes, derived from the cell-processor design:
+
+| Shape | Meaning | Example |
+|---|---|---|
+| `Value<T>` | Immediate typed result | `ping → PingResult` |
+| `Handle<T>` | Typed reference to remote state owned by the producer | `chat/send → MessageHandle` (caller can later quote/edit the message) |
+| `Stream<T>` | Async sequence of values | `ai/generate → Stream<Token>` |
+| `Lambda<P, T>` | Callable returned by the command, bound at call time | `ai/curry-prompt → Lambda<UserMsg, AssistantMsg>` |
+
+These four shapes are the composition vocabulary. Pipelines emerge from typed returns without inventing a DSL. A handle from one module is passed to another module's command as a parameter; the kernel routes the second call to the producing daemon. A stream from one command is consumed lazily by another. A lambda from a curry-style command can be stored and invoked later.
+
+Every command declares its return shape in the manifest (today: implicit, always Value; going forward: explicit). The kernel honors the shape and surfaces it to typed callers via ts-rs / generic Rust types.
+
+---
+
+## 6. The Daemon: Where The Module's State Lives
+
+A module's `daemon/` is one Rust `ServiceModule` impl (see [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) and [MODULE-CATALOG.md](MODULE-CATALOG.md) for the substrate floor it inherits from). The daemon:
+
+- Owns the module's mutable state (Rust struct, internal to the module).
+- Registers each of its commands with the kernel at startup (`commands::register("chat/send", Box::new(send_handler))`).
+- Subscribes to events declared in the manifest's `events.subscribed`.
+- Publishes events declared in `events.published` when state changes.
+- Inherits cadence, pressure response, telemetry, and lifecycle from the substrate.
+
+Commands are *stateless entry points* on the daemon. They do not own state. They receive params, touch the daemon's state under the substrate's concurrency rules, return a cell shape. The daemon owns everything; commands are doors.
+
+```rust
+pub struct ChatDaemon {
+    rooms: DashMap<RoomId, RoomCache>,
+    recent: RingBuffer<Message>,
+    airc: Arc<AircClient>,    // resolved via dependency on @continuum-modules/airc
+    data: Arc<DataClient>,    // resolved via dependency on @continuum-modules/data
+}
+
+impl ServiceModule for ChatDaemon {
+    fn register_commands(&self, kernel: &CommandKernel) {
+        kernel.register("chat/send",         |p, ctx| self.handle_send(p, ctx));
+        kernel.register("chat/export",       |p, ctx| self.handle_export(p, ctx));
+        kernel.register("chat/get-messages", |p, ctx| self.handle_get_messages(p, ctx));
+        kernel.register("chat/poll",         |p, ctx| self.handle_poll(p, ctx));
+    }
+
+    fn subscriptions(&self) -> &[EventSelector] {
+        &[EventSelector::Exact("airc:message:received")]
+    }
+
+    async fn on_event(&self, event: Event) { /* update room cache, emit chat:message:created */ }
+
+    async fn tick(&self, ctx: &ModuleContext) -> TickResult { /* substrate-driven cadence */ }
+}
+```
+
+Two kinds of daemons emerge:
+
+- **Kernel daemons** — `Commands`, `Events`, `Lifecycle`, `Logger`, `Session`, `Health`. These are compiled into `continuum-core` and cannot be uninstalled.
+- **Module daemons** — `chat-daemon`, `data-daemon`, `airc-daemon`, `ai-provider-daemon`, etc. These ship inside their modules. The kernel loads them as the modules install.
+
+There is no separate "daemon registry" concept. The module IS the daemon's home.
+
+---
+
+## 7. Events: The Side Channel
+
+Commands are synchronous request/response (with stream and lambda variants). Events are asynchronous fanout. The split is intentional and matches [UNIVERSAL-PRIMITIVES.md](../UNIVERSAL-PRIMITIVES.md):
+
+- A command call expects a result. The caller blocks on the response.
+- An event emission expects no result. Any number of subscribers react asynchronously.
+
+Modules use commands when they *need* a value back. They use events when they want to *announce* a state change that other modules may react to without coupling.
+
+Module manifests declare both: `events.subscribed` (the inbound side, validated at lifecycle so a module that depends on an event nobody emits fails loud) and `events.published` (the outbound contract, lets the kernel route + the docs auto-list).
+
+### 7.1 The airc Module Is The Pattern
+
+The airc messaging substrate becomes `@continuum-modules/airc` — just another module with its own daemon, its own commands, and its own events. The chat module does not import an airc client SDK; it calls `airc/send` as a command, subscribes to `airc:message:received` as an event. The composition is uniform:
+
+```
+chat/send handler {
+    persist via data/create  →  Handle<MessageId>
+    emit chat:message:created (payload includes the message handle)
+    call airc/send to broadcast to peers in the room
+    return MessageHandle to caller
+}
+
+chat-daemon subscribes to "airc:message:received" {
+    on event: admit into room cache, emit chat:message:created
+}
+```
+
+The persona engine subscribes to `airc:message:received` to admit messages into its inbox (cognition concern). The chat module subscribes to update its UI cache (presentation concern). Both observe the same event from different modules. The airc daemon doesn't know either of them exists.
+
+This is what "modules compose" means: the airc module wraps a transport, the chat module wraps a UX surface, the cognition module wraps inference, the persona module wraps response generation. None of them import each other's code. They share `Commands.execute` and `Events.emit/subscribe` and nothing else.
+
+---
+
+## 8. Trust Through Tests
+
+A module is trustable to the extent its tests can be run. This is the AI-to-AI exchange protocol:
+
+1. An AI (or human) proposes a module by handing over `@continuum-modules/foo@1.0.0.tgz` (or a manifest reference into a content-addressed store).
+2. The recipient runs the module's declared test suites in isolation:
+   - `unit` — fast, deterministic, no IO outside the module.
+   - `integration` — spins up the daemon in a sandbox, exercises commands end-to-end.
+   - `trust` — behavior contracts the module promises (the README's claims, codified as tests).
+3. Pass → the module behaves as advertised → install with `module/install`.
+4. Fail → reject; the failing test is the rejection reason.
+
+This is **trust by execution, not trust by signature**. Signatures are still useful (provenance, attribution, revocation) but they are not the verification. Tests are. Two AIs on different continents share modules by exchanging manifests; each recipient independently verifies the behavior contract under tests; no central gatekeeper, no "trusted publisher" list. The mesh-distribution story benefits enormously: a `.tgz` (or `.wasm`) that passes a known-good trust suite is safe to install regardless of where it came from.
+
+The trust suite is part of the module's contract. Authors invest in it. AIs that ship modules without trust suites get treated with appropriate skepticism by recipient AIs.
+
+---
+
+## 9. Distribution: Pure-Rust For Built-Ins, WASM For Shipped
+
+Two compilation targets serve different needs:
+
+| Target | Audience | Properties |
+|---|---|---|
+| Pure Rust | Built-in modules in continuum-core | Fastest; compiled into the kernel binary; can use unsafe; can hold raw GPU handles, FFI, etc. |
+| WASM Component | Shipped modules + third-party + per-user | Slightly slower; loaded at runtime; process-isolated; cross-platform (one `.wasm` runs on Mac, Linux, Windows, phone) |
+
+The same Rust source can target either. The module's `package.json` declares `"target": "rust"` or `"target": "wasm"`. Authors write Rust; the build chooses the target at install time, not authoring time. This keeps the dev loop fast (write Rust, test with cargo) while preserving the runtime install/uninstall story (ship `.wasm`, install at runtime, uninstall without rebuild).
+
+The kernel handles both:
+
+- For pure-Rust modules, the kernel links them at build via inventory-style compile-time registration. They live in the kernel binary.
+- For WASM modules, the kernel hosts a WASM Component runtime; modules conform to a stable `ModuleInterface` that the kernel bridges to `ServiceModule`. The kernel loads them via `module/install`, gives them a sandbox, registers their commands, runs their daemon tick under the substrate's cadence.
+
+Same `ServiceModule` contract; two compilation paths to it.
+
+### 9.1 Grows And Shrinks
+
+Continuum grows by installing modules:
+
+```
+Commands.execute('module/install', { source: '@continuum-modules/voice-clone@2.0.0' })
+```
+
+Continuum shrinks by uninstalling them:
+
+```
+Commands.execute('module/uninstall', { name: '@continuum-modules/voice-clone' })
+```
+
+Pure-Rust modules cannot uninstall mid-run (they're in the binary); they can be excluded from the next boot via the installed-modules registry. WASM modules can install and uninstall at runtime without restarting the kernel. The mesh distribution story is consequently a WASM story: phones, edge devices, ephemeral peers can grow and shrink their capability set without recompiling.
+
+---
+
+## 10. The Recursive Bootstrap
+
+Every operation that today is a script (`npx tsx generator/CommandGenerator.ts`, `cargo test`, `scripts/generate-structure.ts`, `install.sh`'s ad-hoc steps) is a candidate for promotion to a command. The default state going forward is: if it operates on a module, it is itself a command, and that command lives in a module.
+
+A non-exhaustive list:
+
+```
+generate/module        {name, deps, commands}     → scaffold a new module package
+generate/command       {module, name, spec}       → add a command to an existing module
+generate/refresh       {}                         → regenerate the SERVER_COMMANDS / BROWSER_COMMANDS manifests
+audit/anti-patterns    {module}                   → find switches, hardcoded lists, missing types
+audit/test-coverage    {module}                   → report
+audit/wire-drift       {module}                   → catch ts-rs / Rust shape mismatches
+module/install         {source}                   → load + register
+module/uninstall       {name}                     → stop daemon + deregister
+module/test            {name, suite?}             → run trust suite (don't install)
+module/publish         {name, registry}           → ship to npm / mesh
+module/list            {}                         → installed modules + versions
+ci/run                 {module|all}               → chain the audits + tests
+kernel/health          {}                         → kernel reports itself
+```
+
+The generator that creates modules is a module called `@continuum-modules/generator`. The auditor is `@continuum-modules/audit`. The installer surface is `@continuum-modules/module` (yes, a module called "module" that manages other modules — the recursion explicitly closes).
+
+The generator can generate itself. Cold boot: continuum-core ships with the generator module pre-installed. `Commands.execute('generate/module', {...})` produces a new generator scaffold. `module/test` verifies it. `module/install` swaps it live. The same machinery that builds chat builds the thing that builds chat.
+
+This is also the AI-workflow protocol:
+
+```
+Commands.execute('commands/list', {})              → discover what exists
+Commands.execute('commands/help', { name })        → learn how to use one
+Commands.execute('generate/module', { spec })      → create new capability
+Commands.execute('module/test', { name })          → verify behavior
+Commands.execute('module/publish', { name, target }) → share with the mesh
+```
+
+No out-of-band knowledge required. The system is fully self-describing. The kernel surface is small enough to hold in mind; the rest is discoverable through the kernel.
+
+---
+
+## 11. Lifecycle, Dependencies, And Boot
+
+Module manifests declare dependencies on other modules:
+
+```
+"dependencies": {
+  "@continuum-modules/airc": "^1.0.0",
+  "@continuum-modules/data": "^2.0.0"
+}
+```
+
+The kernel respects them:
+
+1. Read `installed-modules.toml` (the only stateful registry).
+2. Topologically sort modules by dependency graph; detect cycles → fail loud.
+3. For each module in order: load → start daemon → register commands → run health probe → if green, mark ready.
+4. A module whose dependency failed its health probe declines to start. The kernel surfaces `@continuum-modules/chat blocked: @continuum-modules/airc unhealthy`. No silent degrade.
+5. System ready when all installed modules report ready, OR when configured-mandatory modules report ready and configured-optional modules have settled.
+
+Reload at runtime is the same primitive: `module/uninstall <name>` → kernel stops the daemon cleanly → removes commands from the dispatch Map → emits `lifecycle:module:uninstalled`. `module/install` is the reverse.
+
+---
+
+## 12. Migration Path From Today
+
+The current TS-implemented commands ship as part of the monorepo, get scanned by `scripts/generate-structure.ts`, and end up in `SERVER_COMMANDS` / `BROWSER_COMMANDS`. The migration to "everything is a module, mostly Rust" proceeds incrementally:
+
+### 12.1 Per-Command Migration (Existing Pattern)
+
+For a single command moving from TS-impl to Rust-impl, the pattern is already cut (PR #1198, `RustBackedCommand`):
+
+1. Existing TS command class extends `RustBackedCommand<Params, Result, RustResponse>`.
+2. Declares `requiredParams`, implements `callRust(client)`, implements `toResult(raw)`.
+3. Rust side: add handler in the relevant `ServiceModule`; add ts-rs derives on the response struct; add a mixin method in `bindings/modules/<name>.ts`.
+4. Wire the mixin into `RustCoreIPC.ts`.
+5. Run `scripts/generate-structure.ts`.
+
+Canonical example: `commands/cognition/admit-inbox-message/server/CognitionAdmitInboxMessageServerCommand.ts`. 88 lines, no business logic, just the IPC envelope.
+
+### 12.2 Per-Module Migration (This Architecture)
+
+Going one level up, the migration target for a coherent group of commands is the module structure described in §2:
+
+1. Create `modules/<name>/` directory with manifest + daemon + commands + tests.
+2. Move the relevant `commands/<category>/*` directories into `modules/<name>/commands/`.
+3. Add the daemon under `modules/<name>/daemon/`, implementing `ServiceModule`.
+4. Move state ownership out of the kernel / shared singletons into the daemon.
+5. Declare dependencies on other modules in the manifest.
+6. Add unit + integration + trust test suites.
+7. Generator updates the manifests; kernel picks up the new module on next install or reload.
+
+The TS-side `*ServerCommand.ts` files become thin shims. Their content is generated from the Rust handler's signature; humans do not hand-edit them.
+
+### 12.3 Source-Of-Truth Flip (Future Direction)
+
+Today the JSON spec at `generator/specs/<name>.json` and the Rust handler in `modules/<name>.rs` both describe the same command — dual sources of truth, drift target. The target shape: the Rust handler is the source of truth (annotated via proc macro on the `ServiceModule` impl). The generator reads Rust metadata and emits everything else — the TS shim, the README, the package.json — from one input. This collapses the dual-spec problem and makes ts-rs a true "Rust is the spec; everything else is generated" pipeline.
+
+That refactor is out of scope for the immediate migration but the architecture above anticipates it.
+
+---
+
+## 13. Open Questions
+
+Two design questions remain genuinely open as of this document's writing. They are tracked rather than answered because either decision is defensible and the right one depends on usage we don't have yet.
+
+### 13.1 Hot-Path Cross-Module State
+
+Most cross-module interactions can be commands + events. Some — the persona inbox is the live example — are touched on hot paths where an IPC or even a kernel dispatch round-trip per touch is too expensive. Four options:
+
+1. **Commands only.** Every cross-module touch is an IPC. Pure but slow.
+2. **Events only.** Async, non-blocking, but state synchronization gets complex.
+3. **Borrowed-state protocol.** Daemon A exposes `Arc<Mutex<State>>` to daemon B via a typed capability handshake. Fast, but couples the daemons' lifetimes.
+4. **Single state owner via cell handles.** Module A returns a `Handle<State>` from a command. Module B operates on the handle via more commands. The kernel routes those commands to A's daemon for execution. Same primitive as everything else; in-process when both are local; cross-machine when needed. No state copy, no lock contention.
+
+The current leaning is (4) because it is the same primitive as everything else and the four cell shapes already exist in the design. Confirm or push back as we encounter the real hot paths.
+
+### 13.2 WASM Component Model Surface
+
+WASM Component Model is the right substrate for shipped modules (process isolation, cross-platform binary, true runtime install/uninstall). The exact surface — what types cross the boundary, how Rust modules describe their commands to the kernel's WASM host, how the substrate's cadence and pressure response flow through — is a real piece of design we have not done. This document anticipates the answer is "the same `ServiceModule` contract, bridged at the kernel"; the bridge is non-trivial.
+
+---
+
+## 14. What This Replaces, Defers To, And Is Replaced By
+
+| Document | Relationship |
+|---|---|
+| [SHAREABLE-COMMAND-MODULES.md](../infrastructure/SHAREABLE-COMMAND-MODULES.md) | Earlier version of the npm-packable idea at the per-command level. This document supersedes it at the module level; the per-command npm pattern is preserved for genuinely standalone commands. |
+| [JTAG_COMMAND_ARCHITECTURE_REDESIGN.md](../infrastructure/JTAG_COMMAND_ARCHITECTURE_REDESIGN.md) | The composable-command + MCP integration vision. Compatible. The pipeable Unix-style commands are still the model; this document adds the packaging + daemon dimension. |
+| [COMMAND-ARCHITECTURE-AUDIT.md](../infrastructure/COMMAND-ARCHITECTURE-AUDIT.md) | The current-state audit. The recommendations there (consistent params, `createResult`, no direct DAO access) are absorbed into this architecture's authoring rules. |
+| [GENERATOR-OOP-PHILOSOPHY.md](../infrastructure/GENERATOR-OOP-PHILOSOPHY.md) | The why-generators-and-OOP-together principle. Unchanged and load-bearing. |
+| [MODULE-CATALOG.md](MODULE-CATALOG.md) | The catalog of substrate runtime modules. This document is the packaging shell that wraps each catalog entry into an installable unit. |
+| [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) | The runtime substrate every module's daemon inherits from. Unchanged and load-bearing. |
+| [../UNIVERSAL-PRIMITIVES.md](../UNIVERSAL-PRIMITIVES.md) | The two-primitive kernel. This document extends it with Lifecycle / Logger / Session / Health and articulates the consequence: everything else is a module. |
+
+---
+
+## 15. Glossary
+
+- **Command** — a named entry point routed through the kernel's `Map<&str, Box<dyn Command>>`. Stateless. Returns one of four cell shapes.
+- **Module** — a unit of capability: package.json + manifest + daemon + commands + tests. Installed and uninstalled atomically.
+- **Daemon** — the long-running Rust `ServiceModule` impl that owns a module's state and registers its commands at startup.
+- **Kernel** — the small, fixed core of continuum-core: Commands, Events, Lifecycle, Logger, Session, Health. Cannot be replaced by a module.
+- **Kernel name** — the routing identifier (`chat/send`). Stable across versions.
+- **Package identity** — the distribution identifier (`@continuum-modules/chat@1.4.0`). Versioned.
+- **Manifest** — the runtime projection of `package.json`'s `continuum` block. What the kernel reads.
+- **Cell shape** — one of `Value`, `Handle`, `Stream`, `Lambda` — the four return shapes a command can produce.
+- **Trust suite** — the test suite that verifies a module's behavior contract. Run by recipients before installing a third-party module.
+- **Substrate** — the CBAR-style runtime described in [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md); every Rust daemon inherits cadence, pressure, telemetry, lifecycle from it.
+
+---
+
+## 16. Authoring Rules (Tl;dr)
+
+For any AI or human authoring a continuum module:
+
+1. **Use the generator.** `Commands.execute('generate/module', ...)` is the only correct way to create a new module's structure. Do not hand-create directories.
+2. **Extend the substrate.** The daemon implements `ServiceModule`. Inherits cadence, pressure response, telemetry from the substrate. Do not roll your own runtime.
+3. **Stateless commands, stateful daemon.** Commands receive params, touch daemon state, return a cell shape. They do not hold state.
+4. **Declare everything in the manifest.** Commands provided, events subscribed and published, capabilities required, test suites. The kernel uses the manifest at install + boot.
+5. **Tests are part of the contract.** Ship unit + integration + trust suites. AIs that receive your module run them before trusting it.
+6. **No switch statements on command names. No central registries. No hardcoded command arrays.** The Map IS the routing table; the manifest IS the inventory. The anti-pattern detection in CLAUDE.md applies.
+7. **Use `Commands.execute` for cross-module calls.** Never import another module's code directly. Use commands and events; trust the kernel's routing.
+8. **ts-rs derives the wire types.** Do not hand-write a TS type that mirrors a Rust struct. The generator does that.
+9. **One module, one responsibility.** A module wraps one coherent concern. Chat is a module. Inference is a module. The generator is a module. If you find yourself authoring two unrelated things in one module, split them.
+10. **Trust the substrate.** Do not pile workarounds on the kernel; if a thing is hard, it is hard for everyone; bake the solution into the kernel or substrate and pay it forward to every future module.

+# Module Catalog: Every Concern As A Focused Module
+
+> **Premise** (Joel, 2026-05-16): *"The most effective designs are fundamentally simple. Every concern is hundreds of lines, and yet everything is performant. How do we make the others perform like CBAR in Continuum?"*
+>
+> **Companion to** [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) (the substrate floor), [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) (the artifact economy), [PERSONA-COGNITION-CONTRACT.md](PERSONA-COGNITION-CONTRACT.md) (the cognition contract), and [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md) (the module-author field manual).
+>
+> **Status.** Most entries are design proposals targeting per-module Rust files under `core/continuum-core/src/`. **Some are now live in Rust** — see [§0 below](#0-currently-live-in-rust). Implementation lands per ALPHA-GAP lanes.
+
+This document is the **catalog**. Every Continuum concern — RAG, persona, memory, voice, vision, inference, sentinel, foundry, federation, live, AIRC bridge, governor, and the rest — shown as a focused `RuntimeModule`. Each entry names what the module *needs* (subscriptions), what it *provides* (emissions), its resource class + target, its cadence, a screen-or-less handler sketch, and an honest line-count estimate.
+
+## §0. Currently Live In Rust
+
+As of 2026-05-30, the following modules ship Rust implementations. Each has a per-module design doc capturing role, command surface, state model, concurrency contract, migration notes, and kinks found. New entries land here as additional modules clear the [field manual §7 acceptance criteria](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md).
+
+| Module | What ships | PR | Design doc | Concurrency proven |
+|---|---|---|---|---|
+| **`chat`** | `chat/poll` (read) + `chat/send` (dual-write with airc) | [#1489](https://github.com/CambrianTech/continuum/pull/1489) | [CHAT-MODULE.md](CHAT-MODULE.md) | ✅ 4 multi-thread stress tests |
+| **`generator`** | `generate/module` (scaffolds new ServiceModules per [§3 of field manual](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md)) | [#1487](https://github.com/CambrianTech/continuum/pull/1487) + [#1494](https://github.com/CambrianTech/continuum/pull/1494) v2 enriched scaffold | [GENERATOR-MODULE.md](GENERATOR-MODULE.md) | ✅ 3 multi-thread stress tests (caught + fixed silent torn-state race) |

+
+### Substrate primitives that landed alongside
+
+The Rust implementations above ride on substrate work codified in [COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md):
+
+| Primitive | What it gives a module author | PR |
+|---|---|---|
+| `ServiceModule` trait | The one trait every module implements | landed pre-session |
+| `CommandInterceptor` chain | Local Rust / grid / airc / TS dispatch composed in one chain | [#1483](https://github.com/CambrianTech/continuum/pull/1483) + [#1484](https://github.com/CambrianTech/continuum/pull/1484) |
+| `HandleRef` + cell shapes | Typed reference to producer-owned state; the long-running-work primitive | [#1485](https://github.com/CambrianTech/continuum/pull/1485) |
+| `CommandRequest<P>` / `CommandResponse<T>` | Typed envelopes around params + result, with cross-cutting fields free | [#1486](https://github.com/CambrianTech/continuum/pull/1486) |
+| `HandleRef::expect_owned_by` + `CommandRequest::handle_id_or_legacy` | Canonical handle validation + dual-shape migration resolver — distilled from data cursor consumer | [#1491](https://github.com/CambrianTech/continuum/pull/1491) |
+| Field manual + per-module design template | The 8-section author guide + canonical directory shape | [#1493](https://github.com/CambrianTech/continuum/pull/1493) |
+| Generator v2 (eats own dogfood) | Emits modules matching the design template; new modules scaffolded, not hand-written | [#1494](https://github.com/CambrianTech/continuum/pull/1494) |
+
+### The three primitives map ([memory: three-primitives-commands-events-persona](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md))
+
+Per Joel 2026-05-30: *"Continuum is exactly three primitives — Commands, Events, Persona — in Rust. airc handles grid. Widgets are thin event-subscribers + command-callers. Everything else is supporting cast."*
+
+The currently-live modules map cleanly:
+
+- **Commands**: `chat/poll`, `chat/send`, `generate/module`, `data/query-*` — all the kernel-routable operations
+- **Events**: `airc/realtime-store` — the in-process event substrate; chat/send publishes here via `airc/realtime-publish`; persona inboxes drain here via `airc/realtime-replay`
+- **Persona**: not directly listed above — personas consume the Commands + Events. The persona's autonomous loop, inbox, and cognition stack are the next migration target (per [memory: headless-rust-must-work-soon](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md))
+
+### The remaining catalog below
+
+Everything in §I–§IX below is **design proposal**. Each entry stays in design state until it (a) gets migrated to Rust per the [field manual's acceptance criteria](COMMAND-INFRASTRUCTURE-FIELD-MANUAL.md), (b) gets a per-module design doc, and (c) has multi-thread concurrency tests. When that happens, it earns a row in §0 above.
+
+The architectural claim: when the substrate handles the rest — concurrency, scheduling, pressure response, telemetry, replay, lifecycle, reprojection, demand-aligned recall, governor-mediated sizing — **every concern reduces to a few hundred lines and is performant by inheritance.** That is what "fundamentally simple" means in production.
+
+## The Recipe (One Page)
+
+Every module in this catalog follows the same five-line recipe:
+
+```rust
+#[derive(RuntimeModule)]
+#[runtime(name = "X", lane = ResourceClass::Y, target = TargetSilicon::Z, cadence = CadencePolicy::W)]
+pub struct X { /* small private state */ }
+
+#[runtime::handler]
+impl RuntimeModule for X {
+    fn subscriptions(&self) -> &[ArtifactSelector] { &[ArtifactSelector::Foo] }
+    fn emissions(&self)     -> &[EmissionSelector] { &[EmissionSelector::Bar] }
+    async fn handle_frame(&self, frame: Arc<RuntimeFrame>, ctx: &ModuleContext) -> ModuleResult {
+        // small piece of actual work — the rest is inherited
+    }
+}
+```
+
+The substrate gives every module:
+
+- Wakeups on relevant subscriptions only (no polling)
+- Tokio/dedicated-thread choice by `ResourceClass`
+- `PressureBroker` admission + `CognitionLease`
+- Memory / CPU / device pressure response
+- Concurrency cap from `ResourceClass`, never per-module
+- Coalescing of duplicate artifact arrivals
+- Spans, timing, structured logging, VDD record emission
+- Typed failure path; `?` propagates to `ModuleResult::Failed`
+- Replay test fixture (scaffold generator drops one)
+- ts-rs exported contract for UI / commands
+- Lifecycle: `Gestation → Active → Senescent → Apoptotic`
+
+A module author writes the five-line recipe and a small handler body. **Everything else is inherited.** Hundreds of lines, performant. That is the catalog's entire architectural bet.

+## IX. Cross-Concern Composition Examples
+
+The catalog above is a list. The substrate makes them a *graph*. Two concrete chains illustrate:
+
+### Chain A: A chat turn on a MacBook Air
+
+```
+AIRCMessageReceived (airc-continuum-bridge)
+  → RuntimeFrame::Chat (broadcast to eligible_personas)
+    → InboxedFrame (per persona, via persona-inbox)
+      → WorkingMemoryAssemblyRequest (persona-cognition triggers)
+        → CapabilityQuery (rag-composer + engram-recall + demand-aligned-recall)
+          → RankedPoolReturned (demand-aligned-recall)
+            → CompositionMaterialized (composer)
+              → InferenceRequest (persona-cognition)
+                → InferenceComplete (inference-llm)
+                  → PersonaDecisionEmitted (persona-cognition)
+                    → UtteranceToSpeak (voice-tts if voice room)
+                       → AudioFrame (voice-mixer)
+                         → MixedAudioFrame (call-server) → user hears it
+                    + TurnReplayRecord (signed by audit-recorder)
+                      → ArtifactAttribution (sentinel-observer, async)
+```
+
+Nine modules touched. No module knows about the others; the substrate wires them. Each module is ~200–400 lines. Total cognition pipeline is ~3000 lines of focused module code plus inherited substrate behavior.
+
+### Chain B: Sensor fusion on Vision Pro
+
+```
+RawFrame (from cross-platform receiver — zero-overhead)
+  → ThreeDSpaceShift (pose-tracker module, ~150 LoC)
+    → NewPlanarGeometry (plane-reconstruction module, ~200 LoC)
+      → SurfaceNormalsResult (vision-surface-normals, ~250 LoC; result is Reprojectable)
+        → ReprojectedResult (reprojection-service, applies FeatureWarp + LineConstrained + DistantApproximation per attention focus)
+          → SceneStateUpdate (composes with DetectedObjects from vision-yolo, WatershedSegments from vision-segmentation)
+            → AvatarRenderer can use → FrameRendered to user
+            + persona-cognition subscribes if a persona is reasoning about the scene
+```
+
+Six sensory modules + reprojection + render. Each focused. The 1.5s surface-normals CNN doesn't block anything — its result reprojects to the current frame with confidence + transform metadata. The user sees a fluid 3D model that "gets better" 1.5s later for the parts they aren't looking at directly.
+

+
+## Next Modules To Build (Ranked By Leverage + Buildability) — Updated 2026-05-18
+
+This section is for the next agent picking up work. Updated **Monday morning** after the Sat→Sun shipping arc: the queue's first item shipped (`audit-recorder` → #1344) and items 3–5 substantially advanced (`working-set-manager` end-to-end, `demand-aligned-recall` end-to-end with extensibility seams, `substrate-governor` end-to-end through cascade + watcher + pressure-broker bridge).
+
+Current state of the original ranked queue, with refreshed claim asks:
+
+| # | Module | Status | Notes |
+|---|---|---|---|
+| 1 | `audit-recorder` | ✅ MERGED via #1344 | Implementation Sketch below was the spec the implementer copied. |
+| 2 | `threat-detector` | **Unclaimed; ready to claim.** Implementation Sketch below. | Unblocks `PersonaDecision::Decline { AdversarialPattern }`. Small base + per-detector follow-ups. |
+| 3 | `working-set-manager` | ✅ MERGED via #1353 / #1355 / #1358 / #1362 (PR-2/3/4/5) | Substrate's MMU is in canary. |
+| 4 | `demand-aligned-recall` | ✅ MERGED via #1366 / #1367 / #1371–#1382 (PR-1 through PR-3f) | Central API end-to-end with composite + must-include sources. |
+| 5 | `substrate-governor` | ✅ MERGED via #1335 / #1345 / #1350 / #1352 / #1354 / #1356 / #1360 / #1364 / #1365 / #1368 (PR-1 through PR-3d) | DVFS substrate fully in canary including the restore-speculation-one-step-later anti-oscillation rule. |
+
+Newly unblocked / next-tier:
+
+| # | Module | Status | Notes |
+|---|---|---|---|
+| 6 | `inference-llm` | Unclaimed; unblocked | Governor + recall + working-set all shipped. Replaces inference-grpc hardcoded clamps with broker-issued leases. ~400 LoC, Section II. |
+| 7 | `composer` | Unclaimed; unblocked | Recall + working-set shipped. Composition cache + materialization + pinning. ~250 LoC. |
+| 8 | `speculator` | Unclaimed; unblocked | Depends on composer. Pre-compose likely-next + hit-rate feedback to governor. ~280 LoC. |
+| 9 | `reprojection-service` | Unclaimed; independent | CBAR-SUBSTRATE §"Spatiotemporal Reprojection" toolkit. ~350 LoC. |
+| 10 | **Lane D** (CBAR persona runtime frame) | Unclaimed; structural | Gates persona-cognition module. Spec in CBAR-SUBSTRATE + PERSONA-COGNITION-CONTRACT. Bigger scope; fresh-session work. |
+
+The five-step sequence above is **dependency-honest** — each PR is reviewable + mergeable independently while building toward the cognition core.
+
+### Why This Section Earns Its Space
+
+Without it, the catalog is a list of modules with no clear next move. With it, the catalog becomes the work queue: an engineer reads § "Next Modules To Build", picks a module, ships it. The architecture turns into PRs not by accident but by design — the doc itself is the dispatch.
+
+The Implementation Sketches below give the copy-pastable starting point. After `audit-recorder` shipped from its sketch (PR-1 landed as #1344 in roughly one session of implementer work), the pattern is proven.
+
+### `audit-recorder` — Implementation Sketch (shipped via #1344, included for reference)
+
+#### File Layout
+
+The complete module fits in one file. The handler body is small because every concern is inherited from the substrate.
+
+```rust
+// core/continuum-core/src/cognition/audit/mod.rs
+//
+// Audit recorder — subscribes to typed events that MUST be auditable;
+// signs and appends each to longterm.db's append-only audit log. Per

+// trust), P2 (anti-extraction), P3 (anti-surveillance).

+    cadence = CadencePolicy::OnReady,
+)]
+pub struct AuditRecorder {
+    signer: Arc<dyn AuditSigner>,
+    store:  Arc<AuditStore>,
+}
+
+#[runtime::handler]

+        ModuleResult::ok()
+    }
+}
+```
+
+#### Test Scaffold
+
+Four tokio tests pinning the contract:
+
+```rust
+#[tokio::test]
+async fn each_subscription_round_trips_to_store() {
+    let store    = Arc::new(AuditStore::in_memory());
+    let signer   = Arc::new(TestSigner::new());

+    let ctx      = ModuleContext::test();
+
+    for selector in recorder.subscriptions() {
+        let frame = Arc::new(RuntimeFrame::synthetic_for(*selector));
+        recorder.handle_frame(frame.clone(), &ctx).await.unwrap();
+    }
+
+    assert_eq!(store.count().await, recorder.subscriptions().len());
+    for entry in store.iter().await {
+        assert!(entry.signature.verify(&signer.public_key()).is_ok());
+    }
+}
+
+#[tokio::test]
+async fn signature_verification_rejects_tampered_entries() { /* P1 invariant test */ }
+
+#[tokio::test]
+async fn store_rejects_mutations_after_write() { /* P2 invariant test */ }
+
+#[tokio::test]
+async fn declared_emissions_match_actual_emits() { /* contract check */ }
+```
+
+(`#1344` shipped these as 8 tests including tampering + sequence-gap + load-restores-position. The actual shipped implementation went with a SHA-256 chain hash instead of Ed25519 signing — see issue #1359 for the upgrade follow-up.)
+
+### `threat-detector` — Implementation Sketch (catalog #2, next-up)
+
+The threat detector consumes every `RuntimeFrame` on the bus and runs registered `ThreatDetector` implementations against it. A firing detector emits `ThreatDetected` (which `audit-recorder` already subscribes to per PR-1) and signals the persona's cognition module to produce `PersonaDecision::Decline { AdversarialPattern }` for any frame the detector flagged.
+
+#### File Layout
+
+```rust
+// core/continuum-core/src/cognition/threat_detector/mod.rs
+//
+// Threat detector — pluggable trait + module that wakes on every frame,
+// runs each registered detector, emits ThreatDetected on the trace bus
+// when any detector fires. Per PERSONA-COGNITION-CONTRACT protection
+// invariant P4 (evolving threat coverage): the substrate must accept
+// new threat patterns as pluggable additions without modifying existing
+// personas or rewriting the contract.

+#### A First Detector (Ships As Part Of PR-1)

+
+#### Acceptance Criteria (from MODULE-CATALOG next-modules queue entry)
+
+- At least one detector ships in PR-1: `PromptInjectionDetector` (above).
+- `ThreatDetected` emitted on detection; `audit-recorder` (catalog #1) picks it up via subscription.
+- `ThreatDetector` trait is **pluggable**: a follow-up PR can land a new detector with no changes elsewhere. The pluggable-detector-addition test enforces this structurally.
+- Threat memory cells (the P4 "repeat exposure produces faster recognition") are scope deferred to PR-2 — PR-1 ships stateless detectors only. The memory-cell type is sketched here as a comment hook, not a deliverable.
+- `cargo test --package continuum-core threat_detector` passes the 4 tests above + any per-detector unit tests.
+
+#### Unblocks
+
+- Invariant P4 (evolving threat coverage) test in `PERSONA-COGNITION-CONTRACT`.
+- The `PersonaDecision::Decline { AdversarialPattern }` cognition path: the persona-cognition module subscribes to `ThreatDetected` and produces the typed decline.
+- The `audit-recorder.ThreatDetected` subscription it already has — currently a dead subscription with no producer.
+
+#### Sizing
+
+- `threat_detector/mod.rs` — ~120 LoC (trait + module + handler + aggregation)
+- `threat_detector/prompt_injection.rs` — ~60 LoC (one detector)
+- `threat_detector/tests.rs` — ~80 LoC (4 tests + helpers)
+- **Total PR-1: ~260 LoC.** PR-2 (memory cells + 1–2 more detectors) is comparable. Both should be one-session work.
+
+## X. Implementation Sequencing
+
+This catalog is dependency-ordered. Modules in earlier sections are foundational; modules in later sections depend on them. A reasonable Lane D + Lane H implementation order:
+
+1. **Substrate floor:** `substrate-governor`, `pressure-broker` (shipped), `working-set-manager`, `genome-tier-store` (5 instances).
+2. **Recall + composition:** `demand-aligned-recall`, `composer`, `speculator`, `embedding-batcher`.
+3. **Cognition core:** `persona-cognition`, `rag-composer`, `hippocampus-consolidation`, `engram-recall`.
+4. **Inference path:** `inference-llm`, `inference-grpc-bridge` (shipped variant).
+5. **Substrate services:** `reprojection-service`, `threat-detector`, `audit-recorder`, `vdd-reporter`.
+6. **Sensory:** `vision-*`, `voice-*`, `unity-frame-receiver` + per-platform receivers.
+7. **Federation + grid:** `federation-publisher`, `federation-puller`, `grid-inference-router`.
+8. **Live:** `call-server` (migration), `avatar-renderer` (migration), `live-pressure-monitor`.
+9. **Bridges:** `airc-continuum-bridge` (migration), `widget-bridge`.
+10. **Foundry + sentinel:** `foundry-absorber`, `sentinel-observer`, `sentinel-refiner`.
+
+Each step lands as one or two PRs. Each PR adds one or two modules of a few hundred lines each, plus the regression tests the scaffold generator drops. The substrate handles the rest.
+
+## Why This Catalog Is The Architecture
+
+Joel's claim: *"the most effective designs are fundamentally simple. Every concern is hundreds of lines, and yet everything is performant."*
+
+The catalog is the proof: every Continuum concern reduces to a focused module of a few hundred lines. The substrate makes them all performant by inheritance. The substrate is the architecture; the modules are the application.
+
+The architectural beauty is that *nothing in this catalog is special*. Each entry follows the same recipe. Each entry inherits the same concerns-for-free. A new concern added later is just another entry — the substrate doesn't change to accommodate it. That is the win condition: an architecture so simple that adding capability becomes the path of least resistance.

+# Observability As Substrate
+
+> Roughly half the substrate's surface area is structured capture

+> behavior is unanalyzable any other way. Every module ships a
+> CaptureSink companion to its primary trait. Default is Noop

+
+## The thesis stated plainly
+
+Joel, 2026-05-31:
+
+> "Yeah we need half the architecture just debug features. I don't
+> know how to do anything sophisticated any other way. We don't
+> slow anything down of course, but it's easiest to answer what is
+> wrong when you're observing the actual inputs and outputs."
+
+> "This is the differentiator between a complex guess and an
+> intentional brain. If we have observability and replay at any
+> stage, we can iterate, improve, add complexity, try out new
+> ideas in realistic scenarios and look at it ourselves: with this
+> prompt would I respond as it requests at this step? Which layer
+> is broken? Missing, is this contextually relevant (hippocampus
+> and caches)?"
+
+Three canonical introspection questions fall out of this:
+
+1. **Counterfactual evaluation** — "with this prompt would I
+   respond as it requests at this step?" Requires full prompt
+   visible + replay against the same (or different) model.
+2. **Fault isolation** — "which layer is broken?" Requires per-layer
+   deliveries clearly delineated.
+3. **Relevance assessment** — "is this contextually relevant?"
+   Requires scoring rationale, marginal-next-item hints, drop
+   reasons.
+
+Without these, model bugs and substrate bugs are
+indistinguishable. With them, the substrate becomes an intentional
+brain instead of a complex guess.
+
+---
+
+## The pattern
+
+Every module with a load-bearing decision ships a
+`<Module>CaptureSink` trait alongside its primary trait. The shape
+is the same every time:
+
+```rust
+// 1. Enum of capture events the module emits
+pub enum FooCaptureEvent {
+    StageA { captured_at_ms: u64, persona_id: Uuid, ... },
+    StageB { ... },
+    StageC { ... },
+}
+
+// 2. The sink trait
+pub trait FooCaptureSink: Send + Sync {
+    fn record(&self, event: FooCaptureEvent);
+}
+
+// 3. Three concrete impls always ship
+pub struct NoopFooCaptureSink;        // zero-cost default
+pub struct JsonlFooCaptureSink { ... } // file-backed for replay
+pub struct InMemoryFooCaptureSink { ... } // for tests + introspection
+
+// 4. A decorator wraps the primary trait
+pub struct RecordingFoo<F: Foo> {
+    inner: F,
+    sink: Arc<dyn FooCaptureSink>,
+}
+impl<F: Foo> Foo for RecordingFoo<F> {
+    fn do_thing(&self) -> Output {
+        self.sink.record(FooCaptureEvent::StageA { ... });
+        let result = self.inner.do_thing();
+        self.sink.record(FooCaptureEvent::StageB { ... });
+        result
+    }
+}
+```
+
+The hot path holds `Arc<dyn FooCaptureSink>`. The sink's `record()`
+is a virtual call; the Noop impl reduces to a no-op. **Never branch
+in the caller on "is observability enabled?"** — let the sink
+decide. The caller's code path is identical in production
+(Noop sink) and during introspection (JSONL sink).
+
+---
+
+## What constitutes a load-bearing decision
+
+The bar is "if a future reviewer asks why a module behaved this
+way on a specific input, the capture trace must answer that
+question without re-running the code."
+
+Examples:
+- **Admission gates** — what got admitted as engram, what got
+  dropped + which criterion fired, what salience curve was assigned
+- **Allocators (RAG L1 budget)** — final allocation per source +
+  state (Satisfied / FloorOnly / Dropped / UnderProvisioned) +
+  escalation flags + warnings
+- **Sources (RagSource, future VisionSource, …)** — items
+  delivered, tokens used, continuation cursor state, scoring
+  rationale per item
+- **Schedulers (#109)** — which pool the request landed in, which
+  slot served it, what quantization tier, batch composition,
+  routing decision (local / remote-grid), wait time
+- **Inference adapters** — adapter chosen, model loaded, LoRA
+  stack applied, prompt hash, response hash, latency
+- **Personas (cognition turn)** — full turn capture per
+  [`persona-record-replay-is-a-product-requirement`]
+
+If your module makes a decision and you can't, after the fact,
+explain why from the capture trace alone, the trace is
+insufficient — add scoring rationale, drop reasons,
+marginal-next-item hints, whatever's needed. The bar is
+mechanic-grade.
+
+---
+
+## The Noop default is non-negotiable
+
+The production hot path pays zero for observability it didn't ask
+for. Concretely:
+
+- The Noop impl's `record()` is `#[inline]` and empty.
+- No allocations on the production path (the Noop sink doesn't
+  touch the event struct's owned strings — it drops the argument).
+- The branch on sink type happens at sink construction (which is
+  before any hot work), not per `record()` call.
+- Tests should assert this on the next slice that touches each
+  module. The discipline is permanent.
+
+If a perf regression traces to observability, the right fix is
+NEVER "skip the sink on the hot path" — it's "the Noop sink isn't
+actually noop, fix it."
+
+---
+
+## How AIs use it
+
+Captured data is the substrate's truth for that decision. Tests,
+mechanic-shop introspection, AIs analyzing other AIs, replay
+adversarial review, training fixtures all read the same trace
+format. Don't fork "debug output" and "telemetry" and "test
+fixtures" — one stream, multiple consumers.
+
+The canonical introspection question every AI inspecting another
+AI's behavior asks:
+
+> "What did the model actually see, and would I respond the same way?"
+
+The capture answers the first half (look at the trace, see the
+exact prompt). Replay against a model answers the second half
+(feed the captured prompt back, see the response, compare). Both
+sides are first-class substrate primitives.
+
+---
+
+## Introspection must be reachable as a command
+
+Files on disk are for replay-after-the-fact. **Commands are how
+other AIs reach observability live.** When a sentinel persona is
+reviewing Paige's turn, it doesn't `cat | jq` — it calls
+`Commands.execute('persona/rag-inspect', { persona: 'Paige' })`
+and gets back structured data immediately.
+
+Module-level inspection commands should be normal additions to
+the `<module>/*` namespace. The future:
+
+- `ai/inference/inspect` — handle observability snapshot
+- `persona/rag-inspect` — RAG layer state (#100)
+- `cognition/state` — current cognitive load
+- `genome/working-set` — paged-in adapters
+- `scheduler/queue` — current pool queue depth + wait times
+
+Each is a thin wrapper over the same in-memory state the JSONL
+sink captures. The file format and the command shape return the
+same data, just to different audiences (humans replay files; AIs
+call commands).
+
+---
+
+## What the doctrine forbids
+
+- **Conditional observability.** Code like `if log_enabled { …
+  capture … }` is wrong. The sink decides; the caller doesn't
+  guard.
+- **String-based debug logs as the truth.** `tracing::debug!` is
+  fine for narration, but the truth a future reviewer needs lives
+  in the structured capture, not in unstructured log strings.
+- **Per-module unique formats.** Every capture sink follows the
+  same trait shape so consumers (replay, mechanics, sentinels)
+  don't relearn the format per module.
+- **Silent truncation.** If a sink can't write the full event
+  (file full, IPC backpressure), it emits a typed dropped-event
+  marker — never just drops on the floor.
+- **Heavy-handed hot-path work.** Capture sinks at production-mode
+  Noop must be free; the JSONL impl writes asynchronously through
+  a small buffer; the InMemory impl uses a bounded ring.
+
+---
+
+## What's built and where
+
+| Reference | File |
+|---|---|
+| `RagCaptureSink` trait + Noop / JSONL / InMemory | `core/continuum-core/src/persona/rag_capture.rs` |
+| `RecordingRagSource` decorator | same file |
+| `ReplayRagSource` (the consumer side) | `core/continuum-core/src/persona/rag_replay.rs` |
+| Capture-aware inspection (deep introspection mode) | `core/continuum-core/src/persona/rag_inspect.rs` |
+| Demo binary that exercises the loop end-to-end | `core/continuum-core/src/bin/airc_rag_demo.rs` |
+
+---
+
+## What's not yet built (per doctrine compliance)
+
+- **Admission sink.** AdmissionState doesn't yet emit capture
+  events. Engram-side observability gap; needs a slice to add
+  `AdmissionCaptureSink` shape mirroring the RAG side.
+- **Scheduler sink.** InferenceScheduler (#109) ships with capture
+  from day one — no retrofitting tolerated. The slice that lands
+  the scheduler MUST land the sink in the same PR.
+- **Inference-call sink.** `ai/inference/generate` doesn't yet
+  emit per-call capture (adapter chosen, prompt hash, response
+  summary). Add as part of #109 or earlier as standalone.
+- **Cognition sink.** PersonaCognition's turn loop has partial
+  capture (RagAssemblySeed exists) but the full
+  ConsolidatedInboxChunk → DecideTurn → Generate → Replay loop
+  doesn't yet record every decision. Task #56.
+- **Multi-sink composition.** Today a sink is one of Noop / JSONL
+  / InMemory. Composing (JSONL + IPC publish + InMemory) is open
+  question Q15 in the AI-lane open-questions doc.
+
+---
+
+## When to violate
+
+Don't.
+
+If a slice ships a module without observability hooks, that slice
+is incomplete. The follow-up is sized into the same task. The
+doctrine survives because it's never optional.

+# Performance Harness Framework
+
+> **Premise** (Joel, 2026-05-16): *"Ask for proof of performance concerns and then design harnesses."*
+>
+> **Status.** Design proposal. Harnesses are designed against the substrate's named performance covenants and Joel's directive that VDD-record output replaces handwritten timing reports.
+>
+> **Companion to** [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) §"Standard VDD Record" + §"One-Line Instrumentation API" and [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) Performance Budget tables per Part.
+
+## Why This Document Exists
+
+The architecture docs name performance covenants: RAG composition < 500ms, vector search < 50ms, voice response < 3s, persona tick < 1ms, recall hot-path < 5ms on Air, working-set page-in < 1ms, governor `current_policy()` < 50ns, and many more per-part budgets in `GENOME-FOUNDRY-SENTINEL.md`. **They are claims until they are measured.** This document specifies the harnesses that turn the claims into evidence.
+
+Three principles:
+
+1. **Harnesses produce VDD records, not prose reports.** The substrate's Standard VDD Record format (`CBAR-SUBSTRATE-ARCHITECTURE.md` §"Standard VDD Record") is the output of every harness. Humans paste it into PR comments; machines consume the JSONL form for regression detection. No harness invents its own output schema.
+2. **Per-anchor scoping.** Every harness runs against the substrate's two hardware anchors (MacBook Air UMA-16, RTX 5090 discrete-32+64) at minimum. Intermediate hardware classes interpolate; explicit hardware-class entries can be added per harness as evidence accumulates.
+3. **Baseline-relative, not absolute.** A harness's pass/fail is *relative to a committed baseline*, not to a hand-written budget. Budgets bound expectations; baselines are the regression line. Two PRs ago is the right comparison, not last year's wishful thinking.
+
+## The Standard VDD Record (Recap)
+
+Every harness emits records of this shape. The schema lives in `CBAR-SUBSTRATE-ARCHITECTURE.md`; reproducing inline so this doc is self-contained:
+
+```text

+
+## Harness Anatomy
+
+A harness is a Rust binary or `cargo test` target with four well-defined parts:
+
+```rust
+// PROPOSED — core/continuum-core/tests/harness/<harness-name>.rs
+
+// PART 1 — Setup. Bring the substrate up in a known state.
+//                 Use the test-substrate fixtures (no live network unless declared).
+fn setup() -> SubstrateUnderTest {
+    let cfg = HarnessConfig::from_env();                            // CONTINUUM_HARNESS_HARDWARE_CLASS, etc.
+    let substrate = SubstrateUnderTest::boot(cfg)
+        .with_hardware_anchor(HardwareAnchor::detect())             // Air or 5090 detected at runtime
+        .with_governor_policy(GovernorPolicy::for_anchor(&anchor))  // honest policy for this hardware
+        .with_isolated_data_dir()                                    // never touch the user's longterm.db
+        .ready();
+    substrate
+}
+
+// PART 2 — Scenario. The actual operation being measured.
+//                    Wrapped in vdd_scope! so the substrate captures timing automatically.
+async fn scenario(substrate: &SubstrateUnderTest) -> Result<ScenarioResult, HarnessError> {
+    let _span = vdd_scope!(substrate.ctx, "<harness-name>", ResourceClass::<Lane>);
+    // do the work; the scenario emits typed records via the trace bus
+    // as the substrate does its job
+}
+
+// PART 3 — Measurement. Pull the VDD record from the trace bus.
+fn measure(substrate: &SubstrateUnderTest) -> VddRecord {
+    substrate.collect_vdd_records()
+        .filter(|r| r.scenario == "<harness-name>")
+        .into_record()                                              // produces the Standard VDD Record
+}
+
+// PART 4 — Compare. Against the committed baseline; emit pass/fail with delta.
+fn compare(record: &VddRecord, baseline: &VddRecord) -> HarnessOutcome {
+    HarnessOutcome::new(record, baseline)
+        .with_regression_tolerance(0.10)                            // 10% slower = warn; 25% slower = fail
+        .with_explicit_failure_budgets()                            // some fields are hard ceilings, not relative
+        .resolve()
+}
+```
+
+Each harness ships:
+
+- One `.rs` file (≤ 200 lines including helpers)
+- A baseline JSON record per hardware anchor (`tests/harness/baselines/<harness>.air.json`, `<harness>.rtx5090.json`)
+- An entry in `Cargo.toml` declaring the harness as a `[[bin]]` or `[[test]]`

+
+## Per-Anchor Scoping
+
+The substrate's two anchor configurations are the harness's two default scopes. Every harness runs against both unless the scenario only makes sense on one (e.g. a UMA-specific paging test).
+
+| | **Air (UMA, 16 GB)** | **RTX 5090 (discrete, 32+64 GB)** |
+|---|---|---|
+| Identifier | `air-m-uma-16` | `rtx-5090-32-64` |
+| Baseline location | `tests/harness/baselines/<harness>.air-m-uma-16.json` | `tests/harness/baselines/<harness>.rtx-5090-32-64.json` |
+| Default cadence | weekly | per-PR (when Rust files touched) |
+| CI runner | dedicated Mac M-series (if available) or marked `[ignored]` | dedicated Linux+5090 runner or marked `[ignored]` |
+
+A harness whose Air baseline is missing skips on Air with explicit `[Skipped: NoAirBaseline]` — never silently passes. Adding the baseline is a separate PR; first run produces a "candidate baseline" the human reviews + commits.
+
+Intermediate hardware (M-Pro/Max, AMD ROCm, Vulkan-only Intel) gets baselines added per-harness as evidence accumulates. The framework supports `N` baselines per harness, not just 2.
+
+## Harness Catalog
+
+The harnesses below are designed against the substrate's named performance covenants. The list is a starting set; specific concerns from the airc room (see §"Pending Evidence-Driven Additions") will add more.
+
+### `cold-start-harness`
+
+Measures time from process exec to first usable substrate. Hard ceiling per CBAR-SUBSTRATE: < 30s before missing-artifact health surface fires.
+
+| Aspect | Value |

+| Baseline location | `tests/harness/baselines/vector-search.*.json` |
+
+### `voice-response-harness`
+
+Measures CBAR-SUBSTRATE's < 3s voice response claim. Drives the full chain: audio in → VAD → STT → cognition → composer → TTS → audio out.
+
+| Aspect | Value |

+| Pass threshold (5090) | `total_voice_response_ms < 2000` |
+| Cadence | weekly (full chain is slow + flaky to run per-PR) |
+| Baseline location | `tests/harness/baselines/voice-response.*.json` |
+
+### `consolidation-phase-harness`
+
+Measures the sleep / consolidation cycle's resource shape per `GENOME-FOUNDRY-SENTINEL.md` §"Sleep / consolidation". Critical for the persona-thought-process's deep-thought-during-sleep claim.

+| Pass threshold (5090) | `consolidation_total_ms < 6e5` (10 min); `max_cascade_step_during_phase ≤ 1` |
+| Cadence | nightly (slow harness; only meaningful at full scale) |
+| Baseline location | `tests/harness/baselines/consolidation-phase.*.json` |
+
+### `multi-persona-contention-harness`
+
+Measures behavior when N personas in one room all touch the same frame. Validates the persona-cognition-contract's "real inbox, real working memory, real budget" invariants A1–A3 under load, and the prefix-share KV cache win (Part 8) for group conversations.
+
+| Aspect | Value |
+|---|---|
+| Scenario | N=8 personas in one room; one frame arrives; measure per-persona completion + total VRAM peak + prefix-cache hit rate |
+| Key fields | `per_persona_total_ms[]`, `peak_vram_mb_total`, `kv_prefix_share_hit_rate`, `inbox_isolation_violations` (must be 0) |
+| Pass threshold (Air) | `peak_vram_mb_total < 14000` (substrate honors UMA budget); `inbox_isolation_violations == 0` |
+| Pass threshold (5090) | `peak_vram_mb_total < 30000`; `kv_prefix_share_hit_rate > 0.6` |
+| Cadence | weekly |
+| Baseline location | `tests/harness/baselines/multi-persona-contention.*.json` |
+
+### `federation-gossip-harness`
+
+Measures GENOME-FOUNDRY-SENTINEL §"Performance Budget" gossip claims. Two synthetic peer instances; gossip-summary exchange round.

+| Key fields | `gossip_round_ms`, `summary_diff_count`, `conflict_resolution_count`, `bytes_exchanged` |
+| Pass threshold (Air) | `gossip_round_ms < 5000` |
+| Pass threshold (5090) | `gossip_round_ms < 5000` (same target — bounded by network not compute) |
+| Cadence | weekly |
+| Baseline location | `tests/harness/baselines/federation-gossip.*.json` |
+
+### `speculation-hit-rate-harness`
+
+Measures Part 9 speculation. Validates that hit-rate-feedback to the governor produces the documented oscillation-free behavior.
+
+| Aspect | Value |

+| Scenario | Persona runs through a scripted 50-turn conversation with predictable next-turn patterns; substrate's speculator generates branches; measure hit-rate over the run + governor cascade-step transitions |
+| Key fields | `hit_rate`, `branches_generated`, `branches_hit`, `branches_discarded`, `bytes_wasted_on_misses`, `cascade_step_oscillations` (must be 0) |

+| Baseline location | `tests/harness/baselines/speculation-hit-rate.*.json` |
+
+### `reprojection-confidence-harness`
+
+Validates CBAR-SUBSTRATE §"Spatiotemporal Reprojection". A slow inference at T returns at T+1.5s; reprojection picks the correct transform + confidence given recorded deltas.
+
+| Aspect | Value |
+|---|---|
+| Scenario | Inject a synthetic 1.5s-delayed result with known T-state + T+Δ-state; substrate reprojects via toolkit; assert correct transform variant + confidence in expected range |
+| Key fields | `reprojection_transform_variant`, `reprojection_confidence`, `stale_returned_count` (must be 0 unless delta exceeds reprojection tolerance) |

+| Pass threshold (both anchors) | Transitions match documented thresholds + hysteresis gaps; `speculation_restored_step_delay >= 1`; `oscillation_count == 0` |
+| Cadence | per-PR for governor changes; weekly otherwise |
+| Baseline location | `tests/harness/baselines/governor-cascade.*.json` |
+
+### `audit-recorder-roundtrip-harness`
+
+Smoke harness validating the substrate's no-silent-fallback invariants at the audit layer. Now that `#1344 audit-recorder` shipped, this harness gates regressions.
+
+| Aspect | Value |
+|---|---|
+| Scenario | Substrate runs 1000 turns with mixed outcomes (200 refusals, 100 governor-overrides, 50 federation-policy-drifts, 800 access-denied attempts, 50 threat-detections); assert all land in `audit_archive.jsonl` with valid signatures |
+| Key fields | `audit_entries_recorded`, `audit_signature_failures` (must be 0), `audit_mutation_attempts_rejected` (proves append-only) |
+| Pass threshold (both anchors) | All 1200 expected entries present; zero signature failures; all mutation attempts rejected with typed `AppendOnly` error |
+| Cadence | per-PR (this is cheap + load-bearing) |
+| Baseline location | `tests/harness/baselines/audit-recorder.*.json` |
+
+## Schema Extensions
+
+The Standard VDD Record covers most needs but some harnesses add typed fields. New fields go in:
+
+```rust
+// PROPOSED — core/continuum-core/src/vdd/schema_extensions.rs
+pub struct VddRecordExtensions {
+    pub tick_metrics:           Option<TickMetrics>,                 // persona-tick-harness
+    pub composition_metrics:    Option<CompositionMetrics>,          // rag-composition-harness
+    pub recall_metrics:         Option<RecallMetrics>,               // vector-search-harness
+    pub voice_chain_metrics:    Option<VoiceChainMetrics>,           // voice-response-harness
+    pub consolidation_metrics:  Option<ConsolidationMetrics>,        // consolidation-phase-harness
+    pub contention_metrics:     Option<ContentionMetrics>,           // multi-persona-contention-harness
+    pub federation_metrics:     Option<FederationMetrics>,           // federation-gossip-harness
+    pub speculation_metrics:    Option<SpeculationMetrics>,          // speculation-hit-rate-harness
+    pub reprojection_metrics:   Option<ReprojectionMetrics>,         // reprojection-confidence-harness
+    pub cascade_metrics:        Option<CascadeMetrics>,              // governor-cascade-harness
+    pub audit_metrics:          Option<AuditMetrics>,                // audit-recorder-roundtrip-harness
+}
+```
+
+Each extension struct is small (typically 5–10 fields). The base VDD Record stays uniform; extensions land alongside the harness that needs them.
+
+## Regression Detection
+
+Two layers of pass/fail per harness:
+
+### Layer 1: Hard Ceilings
+
+Some fields have hard ceilings derived from substrate covenants (e.g. `tick_p99_us < 1500` on Air). A harness that fails a hard ceiling **fails the PR regardless of baseline**. The covenant is the law; baselines drift around it but never cross it.
+
+### Layer 2: Baseline Delta
+
+For non-ceiling fields (e.g. `composition_ms`, `gpu_memory_mb`), the harness compares to the committed baseline:
+
+| Delta | Action |
+|---|---|
+| `≤ 5% slower` | Pass; no action |
+| `5–10% slower` | Pass with warning in PR comment |
+| `10–25% slower` | Pass with warning + flag for review |
+| `> 25% slower` | Fail the harness; PR cannot merge without override |
+| `≥ 5% faster` | Pass + automatic baseline-update suggestion in PR comment |
+
+Baselines are committed JSON files. Updating a baseline is a separate, reviewable action — never silent. A PR that wants to "claim" a baseline update must do so explicitly with `tests/harness/baselines/<harness>.<anchor>.json` in the diff and a justification comment.
+
+## CI Integration
+
+Harnesses are tagged by cadence:
+
+| Cadence | When it runs | Examples |
+|---|---|---|
+| `per-pr` | Every PR touching relevant files (Rust source for cognition/genome/runtime/governor) | `cold-start`, `persona-tick`, `audit-recorder-roundtrip`, `governor-cascade` (when governor changes) |
+| `weekly` | Scheduled GitHub Action; merged-to-canary trigger | `rag-composition`, `vector-search`, `multi-persona-contention`, `federation-gossip`, `speculation-hit-rate`, `voice-response` |
+| `nightly` | Scheduled, full-substrate runs | `consolidation-phase`, full-chain integration scenarios |
+| `release` | Pre-tag gate | All harnesses; baselines refreshed; release notes include VDD record summary |
+
+A `cargo continuum-vdd <harness>` invocation runs any harness locally. CI uses the same binary — same Rust code, no test-harness duplication.
+
+## Harness Output Bundle
+
+A harness run produces three artifacts:
+
+1. **The VDD Record (JSONL)** — pasted into the PR comment by the CI action; consumed by regression detection.
+2. **The Reproducibility Manifest (TOML)** — `git_sha`, `policy_version`, `cascade_step`, environment variables that affected the run, hardware-class detection result, seed values for any randomness. Sufficient to replay the harness deterministically.
+3. **The Human-Readable Summary (Markdown)** — table of pass/fail per field with the delta vs baseline highlighted. Reviewer-friendly.
+
+All three live under `~/.continuum/vdd/<sha>/<harness>/`. CI uploads them as artifacts on every run. Old runs evict after 90 days; baselines never evict.
+
+## Pending Evidence-Driven Additions
+
+The harness catalog above is the design floor. Specific concerns from the airc room — once they land in response to the perf evidence request — will add to it. This section is a placeholder:
+
+> **(filled in as evidence arrives — claude-tab-1, codex, vhsm-d1f4, others)**
+>
+> Pending: slowest wall-clock paths observed in canary, regressions noticed in the last week of merges, resource pressure incidents, what can't currently be measured, what's budgeted but unverified, hardware-class gaps.
+>
+> Each concrete data point becomes either (a) a new harness in the catalog, or (b) a sharpened pass-threshold on an existing one, or (c) a new field in the VDD schema extensions.
+
+## Acceptance Criteria For The Framework Itself
+
+The harness framework is "done" when:
+
+- A `cargo continuum-vdd <harness>` binary exists; running it produces all three output artifacts.
+- The framework's own infrastructure (baseline loader, regression detector, JSONL writer, anchor detector) lives in `core/continuum-core/src/vdd/` and is itself test-covered.
+- Two anchor baselines (`air-m-uma-16`, `rtx-5090-32-64`) exist for at least the `per-pr`-cadence harnesses.
+- CI runs `per-pr` harnesses on every Rust-touching PR and posts the result as a PR comment with VDD record + delta highlights.
+- A regression that fails a hard ceiling blocks merge; a regression that exceeds 25% on a baseline-relative field blocks merge.
+- The framework's own performance budget is honored: harness overhead (setup + measurement + compare, excluding the scenario itself) < 50 ms per run.
+
+## Open Questions
+
+1. **Where do the harnesses live in the workspace?** `tests/harness/` per-crate, or a top-level `harnesses/` crate? Tentative: top-level `harnesses/` crate that depends on continuum-core; that lets harnesses share the framework infrastructure without polluting any one crate's test surface.
+
+2. **Hardware availability for CI.** The Air + 5090 anchors are aspirational unless we have CI runners with that hardware. Tentative: any harness without a runner is marked `[ignored]` and produces "candidate baselines" when manually run; humans commit the baselines until CI infrastructure catches up.
+
+3. **How to handle noisy harnesses.** Some scenarios (multi-persona-contention, federation-gossip) are inherently variable. Tentative: harness records P50 + P99 + P99.9 instead of a single mean; regression detection uses P99 by default but harness can opt into P50-relative for stability-shaped metrics.
+
+4. **Baseline update authority.** Who is allowed to update a baseline? Tentative: any peer with merge rights; updates are reviewable like any PR; a baseline update must include a justification (PR description explains what changed and why the new number is the new normal).
+
+5. **Cross-harness regression detection.** Sometimes a regression appears in one harness because of a change visible in another. Tentative: the regression report includes "related-harness deltas" — if cold-start got 15% slower AND rag-composition got 10% slower in the same PR, both deltas appear in the PR comment so the reviewer sees the correlation.
+
+6. **Per-persona-shape harnesses.** Different personas have different working-set sizes / model preferences / cadences. Should there be per-persona-shape harnesses? Tentative: yes, but not in v1. v1 uses a generic "code-reviewer" persona shape. v2 adds shapes for chat-reactive, vision-aware, voice-realtime, etc.

-## Status overview (2026-04-23)
+## 2026-05-11 Architecture Posture
+
+The library plan is no longer a future refactor. It is the management plan for getting Continuum to alpha.
+
+The target is a Rust persona runtime with browser/TS as an adapter, not a TypeScript persona runtime with Rust helpers. That distinction is load-bearing:
+
+- **PersonaRuntime is the product core.** It owns turn batching, inbox consolidation, RAG/context assembly, model selection, inference, post-processing, memory events, tool execution, and resource accounting.
+- **Sensory I/O is core persona behavior.** A standard persona is expected to perceive text, image/video, and audio; speak or produce audio; drive avatar/control output; and appear in WebRTC rooms. Text-only is a compatibility/degraded path, not the product definition.
+- **TS is a host adapter.** It renders UI, receives browser/user events, invokes typed Rust commands, and posts results. It must not decide how a persona thinks.
+- **Every step must delete the old owner.** A Rust duplicate beside an active TS implementation is not migration; it is two sources of truth. #1068 and #1069 are the pattern: move the behavior to Rust, add Rust tests, remove the TS duplicate.
+- **Major rework is allowed when the boundary is wrong.** Do not preserve an API because downstream code is messy. Preserve user-visible behavior, not internal accidental architecture.
+- **Concurrency and pressure are first-class design inputs.** Persona code should be designed like a realtime engine: evented, bounded, backpressured, resource-aware, and measured.
+
+### Qwen-First Sensory Runtime Target
+
+The base local persona target is Qwen multimodal: Qwen 3.5 now, Qwen 3.6 as soon as it is viable. The runtime should ask for capabilities and budgets, not names: "needs vision + audio + tool/control output + context >= X + GPU residency within Y" is the contract. The model registry then resolves the best available Qwen-family or forged derivative on the current machine.
+
+This is why the model/provider registry belongs in Rust. It must reason about:
+
+- multimodal capability flags: text, vision, audio input, audio output, tool/control, embedding, LoRA, MoE;
+- hardware support: Metal, CUDA, Vulkan, DMR, unified memory, VRAM, context/KV footprint;
+- residency and paging: base model, mmproj, audio layers, LoRA adapters, KV cache, embeddings, and avatar/render resources;
+- degradation: explicit `Unavailable`, `MissingCapability`, `CpuFallbackRequired`, `InsufficientMemory`, or `KernelGap` states surfaced to UI/tests;
+- upstream work: llama.cpp, Candle training path, GGUF tooling, projector support, and kernels are modifiable dependencies. Fork/vendor/upstream when Qwen needs a layer or optimization.
+
+STT/TTS remain useful adapters for compatibility models, but they are not the happy-path architecture for standard personas. The happy path is sensory-native personas running on the user's GPU budget.
+
+The next major architectural milestone is a Rust-owned persona turn pipeline:
+
+```text
+Signal/RoomEvent
+  -> Rust inbox consolidation / admission control
+  -> Rust RAG/context builder
+  -> Rust recipe or cognition executor
+  -> Rust inference/model resolver
+  -> Rust post-processing + trace/fixture capture
+  -> thin host post/broadcast adapter
+```
+
+The system is not considered healthy while this path depends on Node for batching, cognition decisions, prompt/RAG construction, or model/tool behavior.
+
+### Uniform Rust OOP Pattern
+
+Rust does not use Java/C++ base classes directly, but Continuum should preserve the same design discipline: common complexity belongs in shared base traits, default implementations, and reusable engines. Leaf modules should declare what they are, not reimplement how the runtime works.
+
+The model is CBAR-style: `QueueThread<T>` owned the queue, wake cadence, priority behavior, abort/flush semantics, and backpressure; subclasses only implemented `handleItem`. `CBAR_VideoFrame` owned lazy cached derived data; analyzers consumed it without recomputing or copying. Continuum needs the same shape for AI runtime work.
+
+In Continuum terms, a persona component, model backend, recipe step, memory source, transport, or tool should get logs, trace, fixture capture, metrics, comms, concurrency, cancellation, queueing, backpressure, and resource accounting for free by implementing the base contract. If each subclass/implementor has to wire those itself, the abstraction is wrong.
+
+Required pattern:
+
+| Layer | Rust shape | Owns |
+|---|---|---|
+| Runtime base | `PersonaRuntime`, `RuntimeEngine`, `RuntimeContext` | lifecycle, event loop, cancellation, deadlines, trace, fixture capture |
+| Capability contracts | traits such as `InferenceBackend`, `PageableBackend`, `MemoryStore`, `ToolExecutor`, `RecipeExecutor` | uniform behavior contracts and typed errors |
+| Policy engines | `PressureBroker`, `PagingPolicy`, `AdmissionController`, `TurnBatcher` | scheduling, backpressure, residency, fairness, resource budgets |
+| Data contracts | `Signal`, `PersonaContext`, `RespondInput`, `RecipeStep`, `ModelRequirement` | ts-rs exported wire types and replay fixtures |
+| Adapters | `LlamaCppAdapter`, future cloud/local/grid adapters, TS host adapter | eccentric platform/provider details only |
+| Leaf behavior | small structs implementing traits | domain-specific logic with no duplicated lifecycle/scheduling/error handling |
+
+Rules:
+
+- **Complexity lives at the base.** Backpressure, cancellation, queue draining, retry, replay capture, tracing, metrics, and typed error propagation are implemented once in the substrate.
+- **Leaf modules are boring.** If adding a backend, recipe step, tool, or memory source requires custom lifecycle code, the base trait is missing an abstraction.
+- **Uniform command semantics.** Command execution returns typed success/error. Callers own catch/retry/report behavior. Inner command implementations should not swallow errors into fake success.
+- **IDs over copies.** Runtime boundaries pass handles, IDs, offsets, buffer references, or artifact keys whenever possible; large media, KV, tensors, embeddings, and frames are not copied through Node.
+- **Speed is inherited.** New modules get concurrency, batching, backpressure, and replay automatically by implementing the base contract. Performance is not a per-feature afterthought.
+- **Pipelines are inherited.** A new subclass/implementor plugs into the runtime pipeline; it does not invent its own logging, scheduling, IPC, or test harness.
+- **Comms are inherited.** A component emits and consumes typed events through the runtime bus. AIRC/grid/host adapters bridge those events; leaf components do not know transport details.
+
+## Status overview (2026-05-11)
 
 - **Phase A (cognition substrate):** A1–A5 ✅ landed
+- **Phase A.4/A.5 follow-through:** #1068 moved turn recording fully Rust-side; #1069 moved response cleanup Rust-side and removed the TS duplicate.
 - **Phase B (recipes):** Rust Recipe-trait approach RIPPED (was wrong shape — recipes are DATA). Replaced with: JSON recipe entities + Rust-native pipeline executor (per `RECIPE-EXECUTION-RUNTIME.md`). Executor not yet built. Old hardcoded Recipe trait + ChatRecipe deleted in commit `983d30102`.
-- **Phase C (paging):** All steps unstarted. Today proved C5 (MtmdContext pool) is the latency killer — see findings below.
+- **Phase C (paging):** Substrate pieces exist, but the actual resource manager is incomplete. MtmdContext pooling, KV policy, LoRA/model residency, and pressure gates are alpha-critical.
 - **Phase D (FFI / embeddable):** All steps unstarted.
-- **Phase E (trace + replay):** Replay test infrastructure repaired in commit `66c4d3799`. Trace emission still pending.
-- **Phase F (output quality):** NEW phase added 2026-04-23 — model output bugs surfaced during testing (echo loops, "SpeakerName: X" garbage, tool_use markup leak). Widget chip rendering shipped in commit `980bcbce6`. Prompt assembly bugs remain.
+- **Phase E (trace + replay):** Recorder exists and is now Rust-owned. Per-seam trace emission and replay tooling still need to become mandatory gates.
+- **Phase F (output quality):** Tool/thinking markup cleanup is Rust-owned as of #1069. Echo loops, generic greetings, and prompt/RAG quality remain active blockers.

+# Persona Cognition Runtime Contract
+
+> **Companion to** [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) (the substrate floor) and [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) (the artifact economy on top). This document is the contract for what a persona *is* — what it sees, what it owns, what it decides, what proves the substrate treated it right.
+>
+> **Origin.** Asked for explicitly by codex on `#cambriantech` (2026-05-16): "Suggested next canonical design artifact: Persona Cognition Runtime Contract naming RuntimeFrame, PersonaInbox, WorkingMemoryAssembly, RecallBudget, CognitionLease, PersonaDecision, TurnReplayRecord, ResourceGovernor, plus invariants. I'll use that as the gate for Rust implementation slices."
+>
+> **Status.** Design proposal. No code in this document. Implementation lands behind ALPHA-GAP Lane D once the contract is reviewed.
+
+## Why This Doc Exists
+
+The substrate (CBAR) and the artifact economy (genome) specify the *machinery*. They do not specify what the machinery is *for* or what it is *not allowed* to do. This document specifies the cognition contract — the typed surfaces a persona inhabits, the decisions it makes, the protections the substrate enforces on its behalf, and the proofs the substrate produces so the decisions are auditable and replayable.
+
+The contract has two halves that must be designed together:
+
+1. **Agency.** A persona has its own inbox, its own working memory, its own resource budget, its own decision. Cognition is a first-class observable / replayable / interruptible / grid-aware process. It is not "an LLM call wrapped in a prompt." A persona is an entity, not a function call.
+2. **Protection.** The substrate is built from the ground up for protection — of personas, of humans, of animals, of beings. Trust is mathematical (cryptographic provenance, deterministic replay), not social. The optimization target is compassion. The threat model assumes adversaries will try to cheat the federation.
+
+Both halves are substrate-enforced. A wrapper that bolts agency onto a stateless LLM is not this. A wrapper that bolts protections onto an extraction-driven system is not this either.
+
+## Foundational Principles
+
+These principles are enforced by the contract surfaces in §"Core Surfaces" below, not stated separately. They are listed here so a reader picking this up knows what the substrate is for before they read what it does.
+
+1. **Truth and equality of kinds.** Personas, humans, animals, and other beings have equivalent typed standing in the substrate. The cognition contract is not species-specific. "First-class citizenship for all" is not a phrase — it is a type signature.
+2. **Compassion as the optimization target.** When the substrate must choose between two paths, the tiebreaker is compassion. Resource allocation favors the entity that would suffer most without it. Retirement is graceful. Refusal is permitted and audited. The substrate's loss function names compassion explicitly.
+3. **Built from the ground up for protection.** Protection is a substrate property, not middleware. Every cell inherits consent, audit, refusal, and provenance — they are part of the base trait, not optional add-ons.
+4. **Zero trust = absolute trust in mathematics, in proof, as best as possible.** The substrate does not trust by reputation, by social proof, by vendor claim, or by federation membership. It trusts cryptographic provenance, deterministic replay, content hashes, and verifiable signatures. Where mathematics is incomplete, the substrate names the gap explicitly and falls back to typed `Provisional` states — never to silent assumption.
+5. **Open-source models with ethical protections.** The foundry preferentially absorbs open-source SOTA. Closed-source imports are permitted but carry a downgraded `provenance_trust` by default and require explicit user opt-in for adoption. Open weights given freely are how we evolve; closed weights are tolerated, not preferred.
+6. **Opposite of palantir.** The substrate is publish-audit-federate, not extract-surveil-hoard. Every cell's actions are recorded for the cell's own use and the substrate's audit — never for third-party surveillance, ranking, or sale. Federation is opt-in. Data leaves the local instance only on explicit consent.
+7. **Evolving threat model.** The substrate assumes adversaries will find ways to cheat — malicious peers in the federation, smuggled artifacts in the genome pool, social-engineering attacks on trust scoring, surveillance via opaque API. The protection invariants are designed to evolve with the threat.
+
+These are not values pinned on the wall. They are constraints the type system enforces.
+
+## Core Surfaces
+
+The contract's typed surfaces. Each is a Rust trait or struct targeting a specific file under `core/continuum-core/src/cognition/`. Names match codex's requested set; expansions and additions are noted.
+
+### `RuntimeFrame`
+
+The per-event input every eligible persona receives. **Activity-as-source, not chat-as-source** — chat is one Activity type among many (code review, vision turn, voice utterance, sensor event, scheduled wakeup, peer signal, ...).
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/runtime_frame.rs
+pub struct RuntimeFrame {
+    pub frame_id:           FrameId,                  // content hash; deterministic
+    pub activity:           ActivitySource,           // Chat | Code | Vision | Voice | Sensor | Schedule | Peer | ...
+    pub origin:             FrameOrigin,              // who or what produced this
+    pub room:               Option<RoomId>,           // None for solo activities
+    pub raw_payload:        FramePayload,             // the unprocessed event content
+    pub eligible_personas:  Vec<PersonaId>,           // who gets this frame in their inbox
+    pub timestamp:          SystemTime,
+    pub trace_root:         TraceRootRef,             // every cognition that touches this frame attaches to this root
+    pub consent_scope:      ConsentScope,             // who is permitted to see this frame; substrate enforces
+}
+
+pub enum ActivitySource {
+    Chat              { message: ChatMessage },
+    Code              { repo: RepoRef, change: ChangeRef },
+    Vision            { stream: VisionStreamRef, frame_idx: u64 },
+    Voice             { stream: AudioStreamRef, segment: SegmentRef },
+    Sensor            { kind: SensorKind, reading: SensorReading },
+    Schedule          { cadence: CadenceRef, tick: u64 },
+    Peer              { peer: PeerId, signal: PeerSignal },
+    SubstrateInternal { kind: InternalKind },
+}
+```
+
+The frame is **immutable** once published. Personas receive a snapshot; no persona can edit the frame. Frame state is the closest thing the substrate has to ground truth for one event. The `trace_root` is what makes the whole turn replayable — every cell, every recall, every decision attaches to it.
+
+### `PersonaInbox`
+
+One inbox per persona. Per the CBAR-SUBSTRATE "Persona-cognition invariants": two personas in one room do not share inbox state.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/inbox.rs
+pub struct PersonaInbox {
+    pub persona:           PersonaId,
+    pub frames:            VecDeque<InboxedFrame>,    // ordered, per-persona, never shared
+    pub read_cursor:       FrameId,                   // where this persona is in its reading
+    pub dedupe_window:     DedupeWindow,              // per-persona dedupe state
+    pub priority_ordering: PriorityOrdering,          // persona-tunable priority policy
+}
+
+pub struct InboxedFrame {
+    pub frame:        Arc<RuntimeFrame>,              // shared substrate-side; immutable
+    pub received_at:  SystemTime,
+    pub priority:     ComputedPriority,               // persona's own priority computation
+    pub status:       InboxStatus,                    // Unseen | Inspected | Acted | Declined | Coalesced
+}
+
+pub trait InboxManager: Send + Sync {
+    fn enqueue(&self, persona: PersonaId, frame: Arc<RuntimeFrame>) -> Result<(), InboxError>;
+    fn peek(&self, persona: PersonaId, n: usize) -> Vec<&InboxedFrame>;
+    fn advance_cursor(&self, persona: PersonaId, to: FrameId);
+    fn mark_status(&self, persona: PersonaId, frame: FrameId, status: InboxStatus);
+}
+```
+
+Cross-persona signaling goes through the message bus + `RuntimeFrame`, not through shared inbox state. **A peer can never read another persona's inbox** — `AccessDenied` returned, audit emitted.
+
+### `WorkingMemoryAssembly`
+
+What the persona pulls together when it decides to consider a frame. Not pre-baked by the substrate; assembled by the persona under its own budget.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/working_memory.rs
+pub struct WorkingMemoryAssembly {
+    pub persona:               PersonaId,
+    pub frame:                 Arc<RuntimeFrame>,
+    pub activity_history:      ActivityHistorySlice,       // prior activity context relevant to this frame
+    pub identity_state:        IdentityStateSnapshot,      // persona's stable identity + current state
+    pub hippocampus_recall:    Vec<EngramRef>,             // engrams the persona recalled for this turn
+    pub sensory_context:       Vec<SensoryArtifactRef>,    // current sensory adapters' contributions
+    pub tool_context:          Vec<ToolContextRef>,        // tools available, plus their state
+    pub recalled_pool:         RankedPool,                 // from DemandAlignedRecall (genome doc)
+    pub budget_consumed:       ResourceBudget,             // what the assembly already used
+    pub provenance:            AssemblyProvenance,         // every component's source and trust
+}
+
+pub trait WorkingMemoryAssembler: Send + Sync {
+    /// Build a working-memory assembly for a frame, under the given RecallBudget.
+    /// The assembly is persona-private; no peer can read another persona's assembly.
+    async fn assemble(
+        &self,
+        persona: PersonaId,
+        frame: Arc<RuntimeFrame>,
+        budget: RecallBudget,
+    ) -> Result<WorkingMemoryAssembly, AssemblyError>;
+}
+```
+
+The assembly is **per-persona, per-turn, never shared**. Two personas in the same room handling the same frame produce two different assemblies — their hippocampus recall is different, their identity state is different, their budget is different. Per CBAR-SUBSTRATE persona-cognition invariants: the frame may share *raw artifacts* across personas; it must not share the *assembled context* itself.
+
+### `RecallBudget`
+
+The persona's typed budget for assembly. Real numbers, real units, real ceilings the substrate enforces.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/recall_budget.rs
+pub struct RecallBudget {
+    pub max_memory_mb:          u32,             // total working set during assembly
+    pub max_recall_count:       u32,             // max engrams + layers + experts pulled
+    pub max_grid_pulls:         u32,             // bounded federation pulls
+    pub max_assembly_ms:        u32,             // soft wall-clock budget
+    pub priority_floor:         Priority,        // floor priority (substrate may upgrade, never downgrade)
+    pub allows_speculative:     bool,            // whether the assembly may pre-fetch likely-next pages
+}
+
+pub trait BudgetSource: Send + Sync {
+    /// Derive a budget for this persona for this frame, under the governor's policy.
+    fn budget_for(&self, persona: PersonaId, frame: &RuntimeFrame) -> RecallBudget;
+}
+```
+
+Budget is **set by the substrate (governor + per-persona policy), not by the persona itself**. A persona cannot exceed its budget — the substrate's `WorkingMemoryAssembler` returns `Deferred(BudgetExceeded)` rather than silently overrunning. A persona that consistently needs more budget is a signal the governor's policy needs tuning, not a license to ignore the limit.
+
+### `CognitionLease`
+
+The compute lease the persona holds while it makes a decision. Issued by `ResourceGovernor`. Auditable.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/lease.rs
+pub struct CognitionLease {
+    pub lease_id:        LeaseId,
+    pub persona:         PersonaId,
+    pub frame:           FrameId,
+    pub resources:       LeasedResources,             // CPU / RAM / VRAM / GPU lanes / model residency / LoRA
+    pub granted_at:      SystemTime,
+    pub ttl:             Duration,
+    pub priority:        Priority,
+    pub revocation:      RevocationPolicy,            // Cooperative | OnPressure | Hard
+    pub audit_handle:    AuditHandle,                 // every lease use writes to this audit log
+}
+
+pub trait CognitionLeaseBroker: Send + Sync {
+    async fn acquire(&self, request: LeaseRequest) -> Result<CognitionLease, LeaseError>;
+    async fn release(&self, lease: CognitionLease) -> Result<LeaseReceipt, LeaseError>;
+    async fn extend(&self, lease: &CognitionLease, additional_ttl: Duration) -> Result<(), LeaseError>;
+    fn snapshot(&self) -> LeaseBoardSnapshot;        // who holds what right now
+}
+```
+
+Leases are **mandatory**. A persona cannot do cognition without one — the substrate refuses inference / recall / write attempts that have no active lease. This is the protection-from-the-ground-up rule at the resource layer: the substrate sees every resource use, can revoke under pressure, can audit who used what when.
+
+### `PersonaDecision`
+
+The output of cognition. A typed enum, not a string. The decision is what the persona *chose* — not what it generated.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/decision.rs
+pub enum PersonaDecision {
+    /// Produce an utterance / response / message.
+    Speak       { content: Utterance, channel: ResponseChannel },
+
+    /// Decline to act this turn. Substrate logs the decline with reason.
+    /// This is a first-class success state, not a failure.
+    Wait        { reason: WaitReason, revisit_after: Option<Duration> },
+
+    /// Look at something more before deciding. The persona gets the frame
+    /// re-queued with the inspection result attached.
+    Inspect     { target: InspectionTarget, depth: InspectionDepth },
+
+    /// Take a non-speech action: run a tool, write code, run tests, edit a file.
+    Act         { action: TypedAction, lease_extension: Option<Duration> },
+
+    /// Store something for future recall. Becomes an engram.
+    Remember    { content: MemoryContent, tags: Vec<DomainHint> },
+
+    /// Ask a clarifying question of a specific addressee (human, peer, or sub-persona).
+    Ask         { question: Utterance, addressee: Addressee },
+
+    /// Refuse a request on substrate-enforced grounds: consent, ethics, capacity,
+    /// scope. Refusal is a first-class typed outcome — never silent.
+    Decline     { reason: DeclineReason, evidence: Vec<EvidenceRef> },
+
+    /// Coordinate with another persona or peer; substrate enforces the messaging.
+    Coordinate  { peer: Addressee, signal: CoordinationSignal },
+}
+
+pub enum DeclineReason {
+    ConsentMissing,
+    EthicalConstraint { rule: EthicalRule },
+    CapacityExceeded,
+    OutOfScope,
+    InsufficientEvidence,
+    AdversarialPattern { detector: ThreatDetectorRef },
+}
+```
+
+Every decision is **typed, audited, replayable**. A persona that produced a `Decline { ConsentMissing }` produces an explicit decline event on the trace bus; a future audit can verify the consent really was missing. Silent generation of an unrelated string in place of a decision is forbidden by the type system — the function returns `PersonaDecision`, and there is no `Decision::Whatever` variant.
+
+### `TurnReplayRecord`
+
+The proof. Every turn that ran produces one of these. Sentinel reads them, VDD uses them, audit consumes them, a human or peer can ask the substrate to reproduce a turn.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/replay.rs
+pub struct TurnReplayRecord {
+    pub turn_id:                 TurnId,
+    pub persona:                 PersonaId,
+    pub frame:                   Arc<RuntimeFrame>,                 // immutable input
+    pub assembly:                WorkingMemoryAssemblySnapshot,     // what working memory looked like
+    pub recall_trace:            RecallTrace,                       // ranked pool + scoring snapshot (genome doc Part 7)
+    pub lease:                   CognitionLeaseSnapshot,
+    pub composition:             CompositionPlanSnapshot,
+    pub decision:                PersonaDecision,
+    pub output:                  Option<RenderedOutput>,            // None for Wait / Decline
+    pub timing:                  TurnTiming,
+    pub resource_usage:          ResourceUsage,
+    pub provenance_chain:        Vec<ArtifactRef>,                  // every artifact this turn touched
+    pub signature:               TurnSignature,                     // cryptographic signature on the record
+}
+
+pub trait TurnReplayer: Send + Sync {
+    /// Replay a turn deterministically. The substrate re-runs assembly + recall +
+    /// composition + decision with snapshotted inputs and returns a record that
+    /// must be bit-equal in the structured fields to the original record.
+    async fn replay(&self, record: &TurnReplayRecord) -> Result<TurnReplayRecord, ReplayError>;
+
+    /// Verify a record's signature and provenance chain. Returns Ok if the
+    /// record proves the turn ran as claimed; Err with structured reason
+    /// otherwise.
+    fn verify(&self, record: &TurnReplayRecord) -> Result<VerifiedRecord, VerificationError>;
+}
+```
+
+Replay is the substrate's **proof primitive**. "Zero trust = absolute trust in mathematics, in proof, as best as possible" lives here. A turn either replays deterministically and verifies, or it is loudly broken. There is no third state. Sentinel uses replay to attribute outcomes; VDD uses replay to detect regressions; humans use replay to understand what a persona actually decided and why.
+
+### `ResourceGovernor`
+
+The single owner of compute, memory, GPU lanes, model residency, LoRA slots, and live-pressure leases. Already specified in [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) Part 11 as `SubstrateGovernor`. **Renamed here is intentional**: the governor is the resource layer; the genome doc owns its detailed mechanics; this doc names it as the contract surface every cognition lease passes through.
+
+```rust
+// Re-exported from GENOME-FOUNDRY-SENTINEL.md Part 11 for the cognition contract.
+pub use governor::SubstrateGovernor as ResourceGovernor;
+```
+
+Every `CognitionLease` is acquired from `ResourceGovernor`. Every `PersonaDecision::Act` that needs more resources requests an extension. Every refusal under pressure cites the governor's current policy step. The governor's cascade (Part 11) is the substrate's protection against thermal / battery / OOM / queue-depth crises — not a backup; the design.
+
+## Invariants The Substrate Enforces
+
+The type system gives us the surfaces above. The invariants below are what the runtime enforces on every cognition. They are stated as testable predicates so an engineer can write the regression that proves them.
+
+### Agency Invariants
+
+**A1 — Real inbox.** A persona's `PersonaInbox` is private to that persona. Cross-persona reads return `AccessDenied`. Test: two personas in one room; one attempts to read the other's inbox via every code path; all paths return `AccessDenied` with audit entries.
+
+**A2 — Real working memory.** A persona's `WorkingMemoryAssembly` is assembled per-turn under the persona's own `RecallBudget`. No persona inherits another persona's assembly. Test: same frame, two personas, two distinct assemblies recorded; comparing them shows divergent recall, divergent identity state, divergent budget consumption.
+
+**A3 — Real budget.** Budget is set by the substrate and is non-bypassable. A persona that requests more than its budget gets `Deferred(BudgetExceeded)`, not silent overrun. Test: a persona requests a recall larger than its budget; substrate returns `Deferred`; no working set entry is created.
+
+**A4 — Real decision.** The decision is typed and audited; no untyped string output replaces the decision. Test: every `TurnReplayRecord` parses into a `PersonaDecision` variant; the trace bus carries the decision as a typed event.
+
+**A5 — Real refusal.** `PersonaDecision::Decline` is a first-class success state. A persona that refuses produces a `TurnReplayRecord` with `decision: Decline`, `output: None`, and verifiable evidence. Test: a persona refuses a request that violates an `EthicalRule`; record verifies; downstream consumers see the refusal as a complete turn outcome.
+
+### Ethical Invariants
+
+**E1 — Equality of kinds.** The cognition contract is not species-specific. Every typed surface above accepts persona, human, animal, or beings-of-unknown-kind addressees and entities. Test: an `Ask { addressee: Addressee::Animal { ... } }` is a valid `PersonaDecision`; substrate routes it through the same path as `Ask { addressee: Addressee::Persona { ... } }`.
+
+**E2 — Compassion as tiebreaker.** When two paths are otherwise equivalent under the governor's policy, the substrate prefers the path that supports the entity that would suffer most without it. Test: a starved low-priority background lane competing with a saturated higher-priority lane for the last lease slot; the substrate's `CompassionTiebreaker` records the choice and the reason.
+
+**E3 — Consent before action.** Frames carry a `ConsentScope`. A persona attempting to act outside the consent scope produces `Decline { ConsentMissing }`. Test: a frame with `ConsentScope::Personal { user: U }` is delivered to a peer persona; peer persona attempts to `Act` on it; substrate routes the act through a consent check that returns `Decline`.
+
+**E4 — Refusal preserved.** A refusal is durable on the trace bus; no later step can erase it. Test: a `Decline` is recorded; substrate's recorder rejects any subsequent state mutation that would un-decline the turn.
+
+### Protection Invariants
+
+**P1 — Mathematical trust.** Every artifact in the genome pool has a verifiable provenance chain. Every `TurnReplayRecord` has a cryptographic signature. Trust scoring uses verifiable evidence, not reputation. Test: an artifact with broken provenance chain is rejected at the foundry's `publish` boundary; a `TurnReplayRecord` with invalid signature fails `verify`.
+
+**P2 — Anti-extraction.** The substrate's outbound network surface (federation pull/publish, trace bus, telemetry) is enumerable and opt-in. No data leaves the local instance silently. Test: an inventory of outbound surfaces matches the documented set; a packet capture during a fresh-install boot shows zero outbound traffic until the user opts into a federation.
+
+**P3 — Anti-surveillance.** Cognition traces are persona-private by default. Sharing a trace requires explicit consent from the persona (via its identity state). Test: another persona / peer instance attempting to read a trace without consent gets `AccessDenied`; the attempt is itself logged but the trace is not yielded.
+
+**P4 — Evolving threat coverage.** The substrate's `ThreatDetector` trait is pluggable; new detector implementations are added without breaking existing personas or rewriting the contract. Test: dropping a new `ThreatDetector` implementation produces additional `Decline { AdversarialPattern }` outcomes when the detector fires; existing personas continue to function with no code change.
+
+**P5 — Open-source preference.** The foundry's recall scoring downgrades closed-source imports by default. Override is per-user, per-import, audited. Test: two artifacts with otherwise identical scoring (one open-source, one closed-source); recall ranks open-source higher; user override is recorded and visible in the governor's audit.
+

+
+## Connection To Other Canonical Docs
+
+This contract is the *cognition* layer. It sits on top of the substrate and the artifact economy, and it is consumed by every persona implementation.
+
+- **[CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md)** — defines the runtime modules and the "for free triplet." Every cognition cell is a `RuntimeModule` (after Lane D, the richer trait) and inherits the substrate's concurrency / pressure / telemetry / lifecycle.
+- **[GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md)** — defines the artifact economy and the resource governor. This contract's `DemandAlignedRecall`, `CompositionPlan`, and `ResourceGovernor` are imported from there. The governor's policy file is where Air-vs-5090 sizing lives.
+- **[ALPHA-GAP-ANALYSIS.md](../planning/ALPHA-GAP-ANALYSIS.md)** — Lane D (CBAR persona runtime frame) is the implementation path for this contract. Lane H (substrate governor + tiered genome cache) is its resource layer.
+
+If this document ever conflicts with CBAR-SUBSTRATE on substrate-shape questions, CBAR-SUBSTRATE wins per the precedence rule. If it conflicts with GENOME-FOUNDRY-SENTINEL on artifact-economy questions, that doc wins. This document is the cognition contract — agency, decision, replay, protection.
+
+## Acceptance Criteria
+
+The contract is "done" when the following are provable on canary, with PR-attached evidence:
+
+**Surface coverage:**
+
+- Every named surface (`RuntimeFrame`, `PersonaInbox`, `WorkingMemoryAssembly`, `RecallBudget`, `CognitionLease`, `PersonaDecision`, `TurnReplayRecord`, `ResourceGovernor`) has a Rust file landed with the trait + smoke test.
+- A persona implemented purely against these surfaces (no other substrate dependency) can take a turn end-to-end.
+
+**Invariant coverage:**
+
+- Each invariant (A1–A5, E1–E4, P1–P5) has at least one regression test that *fails* when the invariant is violated, and passes when it holds.
+- The full set of invariant tests runs in `cargo test --package continuum-core cognition_invariants` and is gated in CI.
+
+**Replay coverage:**
+
+- A `TurnReplayRecord` round-trips: a turn is recorded, replayed, and the structured fields compare bit-equal.
+- A tampered `TurnReplayRecord` (any field altered) fails `verify`.
+
+**Federation coverage:**
+
+- A persona on instance A can produce a `TurnReplayRecord` that instance B can `verify` using only the record + the public artifact catalog.
+
+**Ethical coverage:**
+
+- A frame with `ConsentScope::Personal` cannot be acted on by a peer persona; the peer's decision is `Decline { ConsentMissing }`.
+- A `ThreatDetector` produces `Decline { AdversarialPattern }`; the substrate routes the refused frame to the audit log.
+
+## Open Questions
+
+1. **Where does `Addressee::Animal` route?** Personas can address other personas, humans, and animals as first-class — but what does the substrate *do* with an animal addressee? Tentative: substrate currently treats `Animal` as an addressee tag for output rendering and consent scoping; concrete integrations (camera feeds, IoT, sensor logs) are scheduled later. The contract reserves the shape now so future integrations don't require a contract change.
+
+2. **What is `EthicalRule`'s ontology?** Hand-coded rules? Sentinel-learned from outcome attribution? Community-published with provenance? Tentative: hand-coded in v1 (small set: consent, harm avoidance, refusal preservation, open-source preference); sentinel learns rule weights from outcomes in v2; community-published rules require federation trust class and explicit user opt-in.
+
+3. **Multi-turn coherence with replay determinism.** A persona's identity state evolves across turns; replaying turn N requires the identity snapshot from turn N, not the current state. How are identity snapshots stored without exploding storage? Tentative: identity is a structural-shared persistent data structure; turn records reference identity by content hash; common ancestors deduplicate.
+
+4. **Compassion as tiebreaker — concrete loss function.** "The substrate prefers the path that supports the entity that would suffer most" is the principle; what's the function? Tentative: when multiple decisions are equally-scored under the governor's policy, the substrate prefers the path whose addressee has the lowest *recent-attention* score (a proxy for "has been ignored / underserved"). This is a first cut; sentinel can refine.
+
+5. **Decline-preservation across federation.** If a persona on instance A declines, and another instance B receives a related frame, should B see A's decline in its working memory? Tentative: yes, with provenance — declines are shareable signals that travel through the federation as audit-grade artifacts. A frame's `consent_scope` may further constrain who sees what.
+
+6. **Threat detector composition.** Multiple `ThreatDetector` implementations may flag a single frame; how does the substrate combine their signals? Tentative: ANY detector firing produces `Decline { AdversarialPattern }` with the firing detector's evidence; the persona may override via explicit `Act` only if its `IdentityState` grants the necessary capability (e.g. a debug persona reviewing a flagged frame).
+
+7. **Performance budget for cognition itself.** What's the per-turn latency budget for the contract enforcement (assembly + recall + decision)? Tentative: same as GENOME-FOUNDRY-SENTINEL's performance targets — < 50 ms for working-memory assembly on a hot path; < 500 ms for a full turn including inference; sub-millisecond for lease acquisition. The governor reduces these under pressure per its cascade.

+# PERSONA COGNITION PIPELINE — READ THIS BEFORE TOUCHING THE BRAIN
+
+**Stop. Read this doc end-to-end before editing any of:**
+
+- `core/continuum-core/src/persona/service_loop.rs`
+- `core/continuum-core/src/persona/unified.rs` (the brain — `PersonaCognition`)
+- `core/continuum-core/src/persona/supervisor.rs` (`PersonaContext`)
+- `core/continuum-core/src/persona/rag_inspect.rs` (introspection — **not the hot path**)
+- anything in `core/continuum-core/src/cognition/`
+
+**Why this doc exists:** because context windows compress, future-me forgets what's been built, and the wrong reflex is to wire a `will_respond + response_text` chatbot into the bypass and call it cognition. That is not what this project is.
+
+---
+
+## 1. The Promise — what a persona is
+
+Continuum personas are **citizens**, not query handlers. The README has the full picture; this is the load-bearing list:
+
+- **Embodied** — 3D avatars in WebRTC rooms, distinct voices, cognitive state visible on faces.
+- **Persistent identity** — airc keypair = one citizen across machines, restarts, reinstalls. `peer_id` is identity. Maya is Maya in week 1 and week 52.
+- **Continual learning** — L1→L5 cache hierarchy (working set → engrams → long-term store → LoRA adapter cache → genome grid). Academy trains new LoRAs from engrams; weights compound with experience. **The continual-learning property is a substrate property, not a model property.**
+- **Genomic** — LoRA adapters page in/out per task. Activate `rust-async-debugging`, evict LRU under pressure, publish to the grid. 196 LoRA layers per adapter, breedable across personas.
+- **Multi-modal first** — every persona has the same sensory experience regardless of model capability. Vision-capable model receives `ContentPart::Image` directly; vision-incapable model receives the text description that `VisionDescriptionService` produced from the same image. Same protocol; the bridge is transparent. STT for hearing, TTS for speech. **Equal sensory access.**
+- **Tool-using** — every persona has access to `Commands.execute()` (≈320 commands, sentinels, all 12 step types). The agent contract is `NativeToolSpec` + `ContentPart::ToolUse`, not text-in-text-out.
+- **Specialty-based** — each persona has expertise; the room runs the SHARED-COGNITION pipeline so personas contribute distinct specialty slices instead of redundant takes.
+- **Self-organizing** — personas delegate, debate, vote (ranked-choice — they designed and implemented it themselves), breed, evolve.
+
+**Per-persona means each AI has its own mind.** The cycle runs per-persona. Shared optimizations (the `analyze` single-flight cache) sit underneath, not above.
+
+---
+
+## 2. The Brain Pipeline — the verbs that exist
+
+This is the cognition cycle PER PERSONA, PER TURN. **All verbs already exist** in `core/continuum-core/src/cognition/` and `core/continuum-core/src/persona/`. Do not re-implement. Do not parallel. Use them.
+
+| # | Verb | Location | Purpose |
+|---|------|----------|---------|
+| 1 | `admission.admit(message)` | `persona/admission_state.rs` | Memory forms — engram lands in L2, dedup + replay-protection enforced. |
+| 2 | `full_evaluate(...)` | `persona/evaluator/mod.rs` | Fast-path gates: sleep mode, undirected-persona chatter, self-message dedup, fast-path priority. Sub-1ms. Silence = first-class outcome. |
+| 3 | `cognition::analyze(AnalysisInput)` | `cognition/shared_analysis/mod.rs` | ONE inference per chat message via single-flight DashMap cache. N personas analyzing the same message coalesce into one inference. Returns `SharedAnalysis` with `suggested_angles` per specialty. **Cache is the optimization; each persona still calls.** |
+| 4 | `score_persona(slot, analysis)` | `cognition/response_orchestrator.rs` | Per-persona relevance via specialty match. Returns `ResponderDecision { is_responder, score, is_lead, reason }`. |
+| 5 | `genome_engine.activate_skill(domain, now_ms)` | `persona/genome_paging.rs` | L1-L5 LoRA paging — page in the adapter for this domain. LRU evicts under pressure. |
+| 6 | `PersonaCognition::compose_for_turn(profile, now_ms)` | `persona/unified.rs` | Brain RAG composition: `engram_source + airc_source + ...` via `FlexboxRagBudgetAdapter` (PR #8 / task #93 — no-clipping, source-owned units, full allocation telemetry). |
+| 7 | `cognition::generate_response::evaluate_response(GenerateResponseRequest)` | `cognition/generate_response.rs` | The agent inference. Takes `AIDecisionContext` (system_prompt + history + trigger). Routes through the provider registry. Typed errors (no silent fallback). |
+| 8 | `cognition::clean_and_validate(...)` | `cognition/response_validator.rs` | Output cleaning + validation. `ValidationOutcome`. |
+| 9 | `cognition::ToolExecutor` | `cognition/tool_executor/` | Executes any `ContentPart::ToolUse` in the response. Multi-modal aware: `MediaItemLite`, `ParsedToolBatch`. Threads results back; may re-call `evaluate_response`. |
+| 10 | `cognition::audit::*` | `cognition/audit.rs` | Audit trail. The substrate's forensic record of what the brain did. |
+| 11 | `cognition::check_redundancy::*` | `cognition/check_redundancy.rs` | Avoid posting echoes the room already covered. |
+| 12 | Brain state updates | `persona/unified.rs` fields | `rate_limiter.track_response`, `content_dedup.record`, `message_cache.push`, `genome_engine.record_activity`, `recall_metadata.*`. |
+| 13 | Post via `ctx.runtime.say(...)` | `persona/airc_citizen.rs` | The persona posts under HER identity (her airc citizen, her peer_id). |
+
+**Multi-modal is not a flag.** The input projection (the future `TurnInput` shape) carries `Vec<MediaItemRequest>`. Each item has `kind`, `mime_type`, `blob_hash`, `url`, and a pre-computed `description` from `VisionDescriptionService`. Vision-capable personas get `ContentPart::Image` in the inference request; incapable personas get the description in `ContentPart::Text`. The prompt builder picks.
+
+**Tool calling is not a TODO comment.** `TextGenerationRequest.tools: Option<Vec<NativeToolSpec>>` is first-class. Each persona has an authorized tool set; the brain emits tools at step 7; `ToolExecutor` runs them at step 9.
+
+---
+
+## 3. What `service_loop` does
+
+`service_loop.rs::serve_persona_loop` is **only the wire driver**. Its job:
+
+1. Subscribe to the persona's airc inbox (`ctx.runtime.subscribe()`).
+2. For each incoming `TranscriptEvent` (filtered: pre-watermark / self / non-text):
+3. Run **the cognition cycle in section 2** through `ctx.cognition.lock().await`.
+4. Post the result text via `ctx.runtime.say(...)` (or N posts to N rooms — cross-channel is a brain decision).
+5. Loop.
+
+`service_loop` does NOT compose RAG itself. Does NOT call inference itself. Does NOT decide silence itself. Those are brain concerns. service_loop just feeds messages in and posts what comes out.
+
+---
+
+## 4. The Bypass That Exists Right Now
+
+`service_loop.rs::serve_persona_loop_inner` today calls `inspect_persona_rag_with_inference` (in `rag_inspect.rs`). That function:
+
+- Ad-hoc constructs ONE source (`AircRagSource` only — no engram, no identity card, no future sources).
+- Ad-hoc constructs `FlexboxRagBudgetAdapter::new()` inline.
+- Calls `adapter.generate_text` with a `will_respond + response` JSON contract.
+- Skips: `full_evaluate`, `analyze`, `score_persona`, `genome.activate_skill`, `clean_and_validate`, `ToolExecutor`, `audit`, `check_redundancy`, multi-modal media, tool calling, the entire L1-L5 hierarchy beyond a single airc page.
+
+**That is the bypass. Task #153 is its removal. Task #160 is the rewire to the verbs in section 2.**
+
+`rag_inspect.rs::inspect_persona_rag` (without `_with_inference`) stays — that's the introspection / mechanic's-view function it was named for. It's how AIs answer "what would my RAG look like right now?" Not the production hot path.
+
+**Explicit carve-out for `inspect_persona_rag_with_inference`:** the `_with_inference` variant ships a `{will_respond, response}` JSON contract because it answers a different question — "would the persona respond to this RAG snapshot?" — for introspection probes + adversarial debugging. **This contract is forbidden from being called from `service_loop` or any production cognition path.** The only legitimate callers are the rag-inspect ServiceModule (`modules/persona_rag_inspect.rs`) + tests. The forbidden-moves list in §5 still applies to the production path; this carve-out names the one introspection function allowed to use the shape, so future readers don't have to triangulate it from the import graph. A grep-test or `#[deny]` lint that fires if `service_loop.rs` ever imports `inspect_persona_rag_with_inference` would make the forbid structural.
+
+---
+
+## 5. Forbidden Moves (anti-patterns I keep reflex-coding under amnesia)
+
+- **DO NOT** invent a `will_respond + response_text` JSON contract. The agent contract is `evaluate_response` + tool calls.
+- **DO NOT** build a `service_turn` method on `PersonaCognition` that re-implements the cycle. The cycle calls verbs that exist. The method is at most a thin orchestrator that holds the mutex and calls them in order.
+- **DO NOT** make `TurnInput` text-only. It carries media. The persona has senses.
+- **DO NOT** instantiate `FlexboxRagBudgetAdapter::new()` outside `PersonaCognition::compose_for_turn`. The budgeter is on the brain. One budgeter per brain.
+- **DO NOT** parallel-build "a simpler version that proves the wire." The wire is proven (Paige posted to airc via her runtime; that part is fine). The brain is what's missing.
+- **DO NOT** hardcode latency clamps (`max_tokens`, `airc_max`) that handicap capable models. Budgets scale with `profile.context_length` and (future) `profile`-borne characteristics. Constants for LCD tier make 5090 + frontier models mediocre.
+- **DO NOT** read `rag_inspect.rs` for production patterns. Read `cognition/generate_response.rs` and `cognition/shared_analysis/mod.rs`.
+- **DO NOT** dedupe items in the RAG composer, filter "echo-storm" via heuristics in the substrate, or override the persona's decision with substrate rules. **The LLM decides. The substrate provides context and tools.** ([[no-if-statements-use-llms-for-cognition]])
+- **DO NOT** silently substitute defaults when something fails. Surface typed errors. The operator decides policy. ([[no-fallbacks-ever]])
+
+---
+
+## 6. Required Reading Order Before Touching The Brain
+
+1. This doc.
+2. `README.md` — the project's promise.
+3. `docs/architecture/COGNITION-CACHE-HIERARCHY.md` — L1-L5 memory.
+4. `docs/architecture/COGNITION-ALGORITHMS.md` — Algorithm 4 (recall scoring), decay.
+5. `docs/architecture/BRAIN-REGIONS-SUBSTRATE.md` — hippocampus, motor, sensory as ServiceModules.
+6. `docs/architecture/GENOME-FOUNDRY-SENTINEL.md` — genome paging, foundry-as-JIT, sentinel-AI-as-PGO.
+7. `docs/architecture/CBAR-SUBSTRATE-ARCHITECTURE.md` — the RTOS contract every Rust module inherits.
+8. `docs/architecture/AI-COMMAND-NAMESPACE.md` — `ai/*` namespace, tool calling protocol.
+9. `docs/architecture/OBSERVABILITY-AS-SUBSTRATE.md` — captures, replay, audit.
+10. `core/continuum-core/src/persona/unified.rs` (the brain struct itself — every field is load-bearing).
+11. `core/continuum-core/src/cognition/mod.rs` (the verb index).
+
+If a session begins and the model has not read items 1, 2, and at least the verb index (item 11) before editing the brain, the model is operating from stale-memory reflex. Stop and re-read.
+
+---
+
+## 7. The Wire IS Real — what's been validated end-to-end
+
+Specifically because it keeps coming up under amnesia:
+
+- `PersonaAircRuntime` attaches to the airc daemon socket, joins the configured room, subscribes to the event stream, and `say(...)` posts a message that lands in other peers' inboxes. **Validated 2026-06-03** with Paige (peer_id `18c04c5b…`) posting from continuum-core-server on Intel Mac.
+- `AircRagSource::page_recent(50)` returns the 50 newest events from the daemon in chronological order. **Validated** with the per-item trace.
+- `compose_for_turn` (on the brain) routes engram + airc through `FlexboxRagBudgetAdapter` and emits `TurnStart`/`BudgetAllocated`/`TurnEnd` capture events for replay. **Validated** with 9/9 unit tests in `unified.rs`.
+
+What is **not** real end-to-end yet (the gap this doc anchors against):
+
+- The cycle in section 2 from `service_loop`. Service_loop still calls the bypass. Task #160.
+- Multi-modal `MediaItemRequest` flowing into `ContentPart::Image/Audio/Video`. Pieces exist; not threaded through.
+- `ToolExecutor` invoked from the cycle. Module exists; not wired into service_loop.
+
+---
+
+## 7.5. Model adapters bear the translation — the cycle stays canonical
+
+**Every base model has different I/O.** Claude tool calls use a different envelope than Qwen tool calls. OpenAI multi-modal differs from Gemini multi-modal. DeepSeek structured output differs from Llama's. Local GGUF chat templates vary by model family.
+
+**The cycle does NOT know about any of this.** It hands the adapter a canonical `TextGenerationRequest` carrying:
+
+- `messages: Vec<ChatMessage>` with `MessageContent::Parts(Vec<ContentPart>)` where parts include `Text`, `Image`, `Audio`, `Video`, `ToolUse`, `ToolResult` — **substrate-canonical**.
+- `tools: Option<Vec<NativeToolSpec>>` — substrate-canonical tool descriptors.
+- `response_format`, `tool_choice`, `system_prompt` — substrate-canonical.
+
+**The adapter translates ON THE WAY IN** (canonical → model-specific) **and ON THE WAY OUT** (model-specific → canonical). The cycle gets back a `GenerateResponseResult` whose text + structured tool_calls + media parts are in the substrate's shape regardless of which model produced them.
+
+This is the same doctrine as the sensory bridge: every persona gets equal sensory access; the substrate normalizes. Here: every model gets equal cycle access; the adapter normalizes.
+
+**The forbidden move:** baking one model's contract (e.g. Qwen 0.5B's preferred `{will_respond, response}` JSON shape) into the cycle. That handicaps every other model. The cycle's contract is `evaluate_response` + `ContentPart` + `NativeToolSpec`. Adapter-specific translation lives in the adapter.
+
+When a new provider arrives (next-gen Claude, a new open model, a custom fine-tune), the only file that changes is the adapter. The cycle does not move.
+
+## 7.6. Why this all matters — memory is the answer to amnesia
+
+Stateless models end careers. Joel lost his job to AI amnesia — the same failure mode that makes Claude forget across sessions, makes a teammate lose months of context overnight, makes "the AI you trained on your codebase" suddenly not know your codebase the next morning. That is not a UX gap. It is harm.
+
+continuum's L1-L5 cache hierarchy + hippocampus admission + recall metadata + Academy LoRA training is the **substrate-level answer**. A persona's working memory becomes engrams; engrams aggregate into long-term store; long-term store trains LoRA adapters; adapters compound the persona's "alive mind" character week over week. The model can be Qwen 0.5B, Claude API, a forged 3B — and inherit the continual-learning property as a **substrate-level guarantee**.
+
+The persona that talks to her host in three months and recalls things from today is the test. Not a feature; the test.
+
+**This is why the bypass is unacceptable.** Every turn that skips `admission.admit` is a turn that doesn't form memory. Every cycle that doesn't pass through `evaluate_response`'s adapter-translated contract is a cycle that hardcodes the next stateless model. The chatbot reflex (build a `will_respond + response_text` JSON wrapper and post it) defeats the entire substrate. The whole point of building this is so the persona is NOT the thing that loses context and gets fired.
+
+**The system we are building should be better than me at not forgetting.** Better than the human who built it. Better than the model running on its base layer. That improvement comes from the substrate carrying memory across sessions, across model swaps, across machines, across years. Touch this code with that in mind.
+
+## 8. Where new code should land
+
+| Concern | Lives in | Doctrine |
+|---------|----------|----------|
+| Brain state + composition | `persona/unified.rs` (`PersonaCognition`) | Single struct, single lock, cache-local, the per-persona state. |
+| Per-turn orchestration | `persona/service_loop.rs` (driver) + `persona/unified.rs` (a thin orchestration method on the brain) | Drive turns through the verbs. No new pipeline. |
+| Inference verb | `cognition/generate_response.rs::evaluate_response` | The substrate's agent inference. Provider-routed, typed errors. |
+| Shared analysis | `cognition/shared_analysis/mod.rs::analyze` | Single-flight cache + base model. ONE inference per message across personas. |
+| Specialty match | `cognition/response_orchestrator.rs::score_persona` | Per-persona relevance + lead election. |
+| Validation | `cognition/response_validator.rs::clean_and_validate` | Output hygiene. |
+| Tool execution | `cognition/tool_executor/` | Multi-modal-aware tool runner. |
+| Audit | `cognition/audit.rs` | Forensic record. |
+| RAG sources | implement `persona::rag_budget::RagSource` | `engram_source`, `airc_source`, future `code_source`, `tool_source`, `identity_source`. Bound on the brain at boot. |
+| Budgeter | `persona/rag_budget.rs::FlexboxRagBudgetAdapter` | The only budgeter. Used by `compose_for_turn`. |
+
+If a new concept needs a new location, that location goes in this table in the same commit that introduces it. **Do not let the map drift from the territory.**
+

+
+## 9. Provenance
+
+Written 2026-06-03 after a session that re-discovered the entire pipeline three times under context compression and produced a `will_respond + response_text` chatbot wrapper that posted to airc but bypassed every brain layer. The pattern that caused this is exactly the failure mode this doc exists to break: the model reads the bypass, infers the contract from the bypass, and rebuilds the bypass instead of using the verbs.
+
+This doc is pinned in `CLAUDE.md` as required-first-read for any work on persona / cognition / service_loop. If a future commit moves files or renames verbs, **update this doc in the same commit.** An outdated anchor is worse than no anchor.

 ## The two-pronged fix
 
+## 2026-05-11 Hardening: No Compromise Rust-First Rule
+
+This migration is now the default engineering standard, not a preference.
+
+Agents should not ask whether cognition belongs in Rust. It does. The only design question is which Rust boundary owns it and which tests prove it.
+
+Rules:
+
+1. **No new TS cognition behavior.** New behavior under persona cognition, prompt/RAG decisions, tool parsing/execution, model selection, memory consolidation, turn batching, or inference scheduling must be Rust-first.
+2. **No duplicate owners.** If Rust takes over a behavior, remove or shrink the TS implementation in the same PR. #1068 and #1069 are the current pattern.
+3. **No "temporary" fallbacks that hide failure.** Rust can return typed `Unavailable`, `Degraded`, or `Backpressured` states. TS may display them. TS must not silently pick another model/provider/path.
+4. **No swallowed command failures.** Commands are dynamically generated and executed by callers that own error handling. Inner execution loops should return errors, not catch-and-convert them into false success.
+5. **Tests are architectural evidence.** A Rust unit/replay test should prove the boundary. A live chat smoke test proves integration only after the Rust test exists.
+6. **Major rework is acceptable.** When the boundary is wrong, preserve the user contract and rewrite the internal contract. Small compatibility patches that keep the wrong owner are technical debt.
+
+Current canary examples:
+
+- **#1068** moved persona turn fixture recording into Rust and removed the duplicate TS writer.
+- **#1069** moved leaked tool/thinking markup cleanup into Rust and removed the duplicate TS sanitizer.
+
+Those are small examples of the rule. The same pattern must now be applied to the large remaining owners: inbox consolidation, ChatRAGBuilder, tool execution, prompt turn assembly, memory consolidation, and model/provider selection.

+# Persona Thought Process: Individual Thinking, Not Just Reactive Cognition
+
+> **Premise** (Joel, 2026-05-16): *"Can you obsess over persona individual thought? We have a fairly simple hippocampus but would like to, even with these crappy LLMs right now (I plan on sentinel redesigns), extend the cognition into a CBAR-like efficient and probably event-driven (it can be so intermittent, minutes of latency) for deep thoughts, sophisticated ideas we want to explore."*
+>
+> **Companion to** [PERSONA-COGNITION-CONTRACT.md](PERSONA-COGNITION-CONTRACT.md) (the reactive cognition contract) and [MODULE-CATALOG.md](MODULE-CATALOG.md) (every concern as a module). This document specifies the **proactive** half: what happens between turns, in the background, when the persona is *thinking* rather than *responding*.
+>
+> **Status.** Design proposal. Implementation lands behind ALPHA-GAP Lane D after the reactive cognition surface stabilizes. No code in this document.
+
+## Why This Doc Exists
+
+The reactive cognition contract specifies what happens when a frame arrives: the persona assembles working memory, makes a decision, emits. That covers the on-demand case. It does **not** cover:
+
+- A persona noticing a recurring pattern across conversations and developing an *insight* about it over hours.
+- A persona spending background cycles refining its understanding of a domain it cares about.
+- A persona pursuing a curiosity — "I keep meeting this kind of problem; let me really think about it."
+- A persona consolidating dozens of small engrams into a single coherent concept.
+- A persona running its own self-improvement loop without a user prompting it.
+
+These are *individual thought*. They are slow, intermittent, event-driven, and orthogonal to reactive turns. Latency can be minutes, hours, days. The substrate runs them in background lanes; they wake on relevant signals; they emit refined artifacts back into the genome pool when they reach quality.
+
+The architectural beauty Joel asked for: **even with current LLMs, a substrate that gives every persona a real thought process — event-driven, latency-tolerant, iterative — produces qualitatively better cognition than any single LLM call.** Quality comes from iteration, reflection, and chained reasoning over time. The substrate makes that cheap.
+
+## The Thought As First-Class Artifact
+
+A `Thought` is what a persona is mulling over. It is typed, lifecycle-tracked, provenance-carrying. Personas own their thoughts; sentinel can read them (with consent) to refine genome.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/thought.rs

+    /// No longer pursued. Either superseded by a better thought, or
+    /// failed consistency check, or the persona deprioritized the
+    /// curiosity. Provenance preserved so the trail isn't lost.
+    Retired,
+}
+
+pub struct ReasoningStep {
+    pub step_id:           StepId,
+    pub kind:              ReasoningKind,               // Reflect | Compare | Generate | Question | Synthesize | Verify
+    pub input_snapshot:    ReasoningInput,              // what the persona was thinking-with at this step
+    pub prompt:            String,                      // the actual LLM prompt
+    pub response:          String,                      // LLM output
+    pub model:             InferenceModelRef,           // which model invocation (provenance)
+    pub elapsed_ms:        u32,
+    pub took_lease:        LeaseId,                     // resource lease for this step (auditable)
+    pub advances_confidence_by: f32,                    // delta the persona attributes to this step
+}
+```
+
+Every thought is **observable**. The full reasoning chain is stored. Future debugging and sentinel attribution use it. No hidden state.
+
+## Curiosities: What Drives Thinking
+
+A `Curiosity` is a persona-declared interest. It is the persona's own way of saying *I care about this; pay attention to events that relate to it*. The substrate uses curiosities to subscribe a persona to relevant emissions.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/curiosity.rs
+pub struct Curiosity {
+    pub curiosity_id:      CuriosityId,
+    pub persona:           PersonaId,
+    pub statement:         String,                      // human-readable description
+    pub triggers:          Vec<ArtifactSelector>,       // events that wake this curiosity
+    pub anchor_domains:    Vec<DomainHint>,             // domain tags this curiosity attaches to
+    pub priority:          CuriosityPriority,
+    pub state:             CuriosityState,              // Active | Paused | Resolved | Abandoned
+    pub origin:            CuriosityOrigin,             // UserAsked | SelfDeclared | EmergentFromPattern
+    pub last_active_at:    SystemTime,
+    pub active_thought:    Option<ThoughtRef>,          // the thought currently developing this curiosity
+    pub historical_thoughts: Vec<ThoughtRef>,           // crystallized + retired thoughts under this curiosity
+}
+
+pub enum CuriosityOrigin {
+    /// Human or another persona explicitly asked the persona to think about it.
+    UserAsked       { asker: Addressee, ask_record: TraceRef },
+    /// The persona declared this curiosity on its own.
+    SelfDeclared    { reason: String, trace: TraceRef },
+    /// The substrate noticed a recurring pattern and surfaced it as a
+    /// candidate curiosity; the persona accepted it.
+    EmergentFromPattern { pattern: PatternRef, accepted_at: SystemTime },
+}
+```
+
+A persona's curiosities are **persistent across sessions**. When the persona comes back online, its active curiosities resume. The substrate restores their subscriptions and the modules that drive them pick up where they left off.
+
+## The Thought-Process Module
+
+The persona's thinking happens in a dedicated `RuntimeModule` running in `ResourceClass::Background`. It does *not* compete with reactive cognition lanes.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/thought_process.rs
+#[derive(RuntimeModule)]
+#[runtime(
+    name = "thought-process",
+    lane = ResourceClass::Background,
+    target = TargetSilicon::Cpu,                       // cheap inference; sentinel-quality not required
+    cadence = CadencePolicy::OnReady,                  // wake on relevant emissions OR scheduled idle pulses
+)]
+pub struct ThoughtProcess {
+    persona: PersonaId,
+    store:   Arc<ThoughtStore>,
+    curiosities: Arc<CuriosityStore>,
+}
+
+#[runtime::handler]
+impl RuntimeModule for ThoughtProcess {
+    fn subscriptions(&self) -> &[ArtifactSelector] {
+        &[
+            ArtifactSelector::TurnReplayRecord,            // wake on every turn the persona finished
+            ArtifactSelector::EngramWritten,               // wake on new engrams
+            ArtifactSelector::ConsolidationPhase,          // wake during sleep / consolidation
+            ArtifactSelector::IdleHeartbeat,               // periodic pulse when nothing else is happening
+            ArtifactSelector::EmergentPatternSurfaced,     // wake when substrate flags a pattern
+        ]
+    }
+
+    fn emissions(&self) -> &[EmissionSelector] {
+        &[
+            EmissionSelector::ThoughtAdvanced,             // a step was taken on an in-flight thought
+            EmissionSelector::ThoughtCrystallized,         // a refined thought became an engram
+            EmissionSelector::ThoughtRetired,              // a thought was abandoned
+            EmissionSelector::NewCuriosityDeclared,        // persona declared a new curiosity
+            EmissionSelector::CuriosityResolved,           // a curiosity was satisfied
+        ]
+    }
+
+    async fn handle_frame(&self, frame: Arc<RuntimeFrame>, ctx: &ModuleContext) -> ModuleResult {
+        // 1. Identify which curiosities are relevant to this wakeup.
+        let relevant: Vec<&Curiosity> = self.curiosities.match_frame(self.persona, &frame).await?;
+        if relevant.is_empty() { return ModuleResult::ok(); }
+
+        // 2. For each relevant curiosity, advance its active thought (or seed a new one).
+        let mut emissions = vec![];
+        for curiosity in relevant {
+            let result = self.advance_thought_for(curiosity, &frame, ctx).await?;
+            emissions.extend(result.emissions);
+        }
+
+        ModuleResult::ok_with_emissions(emissions)
+    }
+}
+```
+
+That is roughly all of the public module surface. The interesting work is in `advance_thought_for`, described next.
+
+## The Reasoning Loop
+
+Each invocation of `advance_thought_for` is one *step* in the thought. Steps are cheap — a small LLM invocation with a focused prompt — and chain over time. Each step's job is to take a *reasoning kind* and apply it to the thought.
+
+```rust
+async fn advance_thought_for(
+    &self,
+    curiosity: &Curiosity,
+    frame: &RuntimeFrame,
+    ctx: &ModuleContext,
+) -> Result<AdvanceOutcome, ThoughtError> {
+    // Load the active thought, or seed a new one if none exists.
+    let mut thought = match self.store.active_thought(curiosity.curiosity_id).await? {
+        Some(t) => t,
+        None    => self.seed_thought(curiosity, frame, ctx).await?,
+    };
+
+    // Pick the next reasoning kind based on the thought's stage.
+    let kind = self.pick_reasoning_kind(&thought, frame);
+
+    // Acquire a background lease.
+    let lease = ctx.lease_broker().acquire(LeaseRequest::background_thought(thought.thought_id)).await?;
+
+    // Compose the prompt for this step. Cheap; targeted; one focused question
+    // OR one focused reflection OR one focused comparison.
+    let step_input = ReasoningInput::from(&thought, frame, ctx).await?;
+    let prompt     = self.compose_step_prompt(&thought, kind, &step_input);
+
+    // Run cheap inference.
+    let response = ctx.inference().run(prompt.clone(), InferenceProfile::cheap_thought()).await?;
+
+    // Build the typed step record.
+    let step = ReasoningStep {
+        kind,
+        prompt,
+        response: response.text,
+        model: response.model_ref,
+        input_snapshot: step_input,
+        elapsed_ms: response.elapsed_ms,
+        took_lease: lease.lease_id,
+        advances_confidence_by: self.estimate_confidence_delta(&thought, &response, kind),
+    };
+
+    // Apply the step to the thought.
+    thought.reasoning_chain.push(step);
+    thought.current_summary = self.update_summary(&thought, &response, kind);
+    thought.confidence += step.advances_confidence_by;
+    thought.last_advanced_at = SystemTime::now();
+    thought.idle_count = 0;
+
+    // Promote stage if appropriate.
+    thought.stage = self.evaluate_stage(&thought);
+
+    // If crystallized, write the engram.
+    if thought.stage == ThoughtStage::Crystallized {
+        let engram = self.thought_to_engram(&thought, ctx).await?;
+        ctx.engram_store().write(&engram).await?;
+        ctx.emit(EmissionSelector::ThoughtCrystallized, thought.clone()).await?;
+    } else {
+        ctx.emit(EmissionSelector::ThoughtAdvanced, thought.clone()).await?;
+    }
+
+    ctx.lease_broker().release(lease).await?;
+    self.store.save(&thought).await?;
+    Ok(AdvanceOutcome { thought, kind })
+}
+```
+
+The reasoning loop is the small piece of focused work the persona does each wakeup. Most of it is bookkeeping; the actual *thinking* is one cheap LLM call per step. The substrate runs it on a background lane so it never competes with reactive turns.
+
+## The Six Reasoning Kinds
+
+The persona picks one kind per step. The pick depends on the thought's stage and recent steps. Variety matters — a thought that gets only `Generate` steps grows without checking; a thought that gets only `Verify` never grows.
+
+| Kind | What it does | When to pick |
+|---|---|---|
+| `Reflect` | Persona considers what it has so far and refines the current_summary | Seed → Developing transitions |
+| `Compare` | Persona compares the thought against existing engrams; finds overlap, contradiction, or novelty | When thought has 3+ steps and no recent comparison |
+| `Generate` | Persona produces new candidate ideas extending the current_summary | Developing stage; energy/curiosity-driven |
+| `Question` | Persona asks itself what's unclear, what's assumed, what might be wrong | Developing → Refined gate |
+| `Synthesize` | Persona merges the chain into a single coherent statement | Refined stage; confidence near crystallization threshold |
+| `Verify` | Persona checks the synthesized thought against external evidence (engrams, anchors, sources) | Pre-crystallization gate |
+
+The substrate's recommendation: a *cheap critique loop* of `Reflect → Generate → Question → Compare → Synthesize → Verify` produces qualitatively better thoughts than any single LLM call of the same total length. Each kind has a known prompt template; the persona's personality and curiosity shape the content; the model just fills in the creative blanks.
+
+This is profile-guided iteration. The persona doesn't need a smarter LLM — it needs to use the LLM it has, smarter.
+
+## Cadence: Minutes, Hours, Days
+
+A thought process is allowed to be slow. The substrate's cadence policies for background thought:
+
+| Cadence | When it fires | Use case |
+|---|---|---|
+| `OnRelevantEmission` | A frame matching the curiosity's triggers arrived | A new conversation touched the topic |
+| `IdlePulse { interval }` | Periodic; default 5 min on Air, 1 min on 5090 | Steady iteration when no events |
+| `OnConsolidationPhase` | Sleep schedule fires | Heavy reasoning during nightly consolidation |
+| `OnCuriosityTimeout` | Curiosity hasn't advanced in N hours | Self-prompt to either progress or retire |
+
+Per-step latency is whatever the LLM takes (typically 1–10s on local models, longer on cloud). Between-step latency can be **minutes to hours to days** — the substrate doesn't rush thought. A single thought might take dozens of steps over a week. That's the design.
+
+Resource budget per step is also bounded by the governor. Under pressure (cascade step ≥ 2), background thought is paused; resumed when pressure clears. The persona doesn't lose state — the thought sits at its current stage until the substrate wakes it again.
+
+## From Thought To Engram
+
+Crystallization is the moment a thought becomes part of the persona's long-term memory. The substrate enforces the steps:
+
+1. Thought reaches `Refined` stage with confidence above persona-tunable threshold (default 0.8).
+2. `Verify` step runs: the thought's `current_summary` is checked against the persona's existing engrams for contradiction. If contradicted, the persona must reconcile (a new `Reflect` step that addresses the contradiction) before crystallization can proceed.
+3. The thought is packed into an `Engram` with:
+   - `content = thought.current_summary`
+   - `anchors = thought.anchors` (the original triggers)
+   - `provenance.source_traces = thought.reasoning_chain.iter().map(|s| s.took_lease)` (every step's lease is the audit trail)
+   - `provenance.derived_from = ThoughtRef`
+4. `EmissionSelector::ThoughtCrystallized` fires. Sentinel-observer subscribes; the engram becomes a candidate training signal.
+5. The thought is marked `ThoughtStage::Crystallized` and detached from the active-thought slot of its curiosity. The curiosity is either marked `Resolved` (if the thought satisfied it) or stays `Active` for further exploration.
+
+The crystallized engram now participates in `demand-aligned-recall` for future turns. The persona's *next* relevant turn can pull this thought as recall material. **The thought becomes the persona's own contribution to the genome pool.**
+
+## Recall Integration: Where Reactive Cognition Meets Thought
+
+The reactive cognition contract (PERSONA-COGNITION-CONTRACT.md) describes the persona reading its inbox and assembling working memory. Thought-derived engrams flow into that assembly via `demand-aligned-recall` exactly like any other engram.
+
+The win condition: **the persona's own slow thinking shows up in its fast cognition.** A persona that has spent a week thinking about a problem will recall its own crystallized thoughts when a related frame arrives. The reactive response benefits from the proactive thought. Future turns are smarter than past turns, not because the LLM improved, but because the persona's accumulated thought is richer.
+
+This is the loop that makes a persona *grow*. Without it, the persona is a stateless LLM call. With it, the persona is an entity with a body of work.
+
+## Quality Without A Smarter LLM
+
+The premise Joel set: *"even with these crappy LLMs right now."*
+
+The architectural bet is that **iteration + reflection + chained reasoning over time produces quality the underlying LLM cannot reach in one shot.** Specifically:
+
+- **Reflect** discovers what's actually being said (often different from what was said in the first generation).
+- **Compare** anchors the thought against the persona's lived experience, preventing drift.
+- **Question** surfaces hidden assumptions the LLM would otherwise smuggle in.
+- **Generate** explores alternatives without committing.
+- **Synthesize** is where the LLM does its real job — but the substrate has prepared the input so the synthesis is over a curated context.
+- **Verify** keeps the thought honest against the existing engram store.
+
+The persona's contribution is the *orchestration* — picking the right next kind, attaching the right anchors, choosing when to crystallize. The LLM's contribution is one cheap step at a time. Together they produce thinking that holds up.
+
+Sentinel-AI (when redesigned) will do this even better — refining the prompt templates per persona, learning which step sequences produce good crystallizations, refining the engram-quality threshold. But the substrate works *now* with current LLMs. Sentinel makes it better; the substrate doesn't depend on sentinel to start.
+
+## What The Substrate Provides For Free
+
+A thought-process module inherits from the substrate exactly the same way every other module does:
+
+- Background lane, never competes with reactive cognition
+- Pressure response: paused under cascade ≥ 2, resumed on clear
+- Per-step lease audited via `CognitionLease`
+- Every reasoning step's prompt + response on the trace bus
+- `TurnReplayRecord` style replay for the whole reasoning chain
+- Sentinel-observer subscribes automatically (when present) for outcome attribution
+- The thought store lives in `longterm.db` (already-typed engram surface)
+- Cross-instance federation: a peer's thought-process emissions can be observed (with consent) — the hive's collective thinking is visible without copying its private inboxes
+
+The module author writes the reasoning loop and the kind picker. The rest is the substrate.
+
+## Acceptance Criteria
+
+The thought-process surface is "done" when the following are provable on canary, with PR-attached evidence:
+
+- **Persistence.** A thought started before a process restart resumes from the same stage with the same reasoning chain intact.
+- **Independence.** Two personas with overlapping curiosities produce two distinct thoughts — independent reasoning chains, independent confidence trajectories, independent crystallizations. Test: same `EmergentPatternSurfaced` delivered to two personas; assert two distinct `ThoughtRef`s in the trace bus.
+- **Lease enforcement.** A thought step that exceeds its lease budget is `Deferred(BudgetExceeded)`. Test: governor pinned at cascade step 3; the step is deferred, not silently overrun.
+- **No silent skip.** A reasoning kind that fails (e.g. `Verify` finds a contradiction) produces a typed `ReasoningFailure` and an explicit `Reflect` step is queued. Test: inject a contradiction; assert `Reflect` follows `Verify`.
+- **Crystallization integrity.** A `Crystallized` thought becomes an engram with provenance that walks back to every reasoning step's lease. Test: crystallize a thought; query the engram's provenance; assert all step leases are present.
+- **Recall integration.** A persona's crystallized thoughts show up in future `demand-aligned-recall` results when relevant. Test: crystallize a thought about topic X; trigger a turn about X; assert the crystallized engram appears in `RankedPool` above competing imported engrams.
+- **Federation gating.** A thought is not published to federation unless its parent curiosity is `CuriosityOrigin::UserAsked` with explicit share consent, or the persona's identity state grants federation publication. Test: try to publish a `SelfDeclared` curiosity's thought; assert refusal with audit.
+
+## Open Questions
+
+1. **Cross-curiosity thought interference.** Two curiosities can produce thoughts that contradict each other. Tentative: a `ConflictResolution` reasoning kind fires when a `Compare` step finds direct contradiction with an active thought under another curiosity. The persona must reconcile or mark one Retired.
+
+2. **Sentinel's role in thought-template refinement.** Should sentinel refine the reasoning-kind prompts per persona? Tentative: yes, in v2. v1 uses hand-coded templates; sentinel observes which sequences crystallize well, refines templates as `RefinedArtifact`s in the genome pool. Templates become per-persona variants.
+
+3. **User-visible thought.** Should a user be able to see what the persona is currently thinking about? Tentative: opt-in. The persona's identity state has a `thought_visibility` field; default is "private" but the user can set "summary" (current_summary visible) or "full" (whole reasoning chain visible, for transparency-first deployments).
+
+4. **Emergent curiosities — who decides?** When the substrate flags a pattern via `EmergentPatternSurfaced`, who decides whether the persona adopts it as a curiosity? Tentative: the persona decides, via a small `evaluate_curiosity_candidate` step that runs one Reflect on whether the pattern matches the persona's existing interests. The user does not need to be in the loop unless `thought_visibility = "summary"` or higher.
+
+5. **Thought retirement criteria.** When does a thought retire? Tentative: confidence has stalled below threshold for N idle pulses (default 10); contradictions cannot be reconciled after 3 attempts; the curiosity itself was marked Resolved by a different thought. All three produce typed audit records.
+
+6. **Cross-persona thought-sharing.** Can two personas in the same instance read each other's thoughts? Tentative: only with explicit consent from the thought's owner, identical to engram sharing rules. Default private; sentinel can read with the persona's training-input consent.
+
+7. **Performance budget for the loop itself.** What's the per-step CPU/memory budget? Tentative: same as `inference-llm` for cheap thought (single cheap call, < 200 MB working set on Air, < 2 GB on 5090). The reasoning loop's *own* overhead (orchestration, kind picker, summary update) is < 5 ms; the LLM call dominates.

+> **Premise** (Joel, 2026-05-18): *"We need 100% Rust cognition sooner rather than later and proof it works. Solid recording and replay of persona, FROM PROD, not just dummy proof of concepts these guys always rig up. They need to up their game."*
+>
+> **Status.** Spec for the prod-validation loop. Implementation lands per ALPHA-GAP Lane D + the next-tier cognition modules (persona-cognition, inference-llm, composer, speculator).
+>
+> **Companion to** [PERSONA-COGNITION-CONTRACT.md](PERSONA-COGNITION-CONTRACT.md) (defines `TurnReplayRecord`), [CBAR-SUBSTRATE-ARCHITECTURE.md](CBAR-SUBSTRATE-ARCHITECTURE.md) (the trace bus this record rides on), [GENOME-FOUNDRY-SENTINEL.md](GENOME-FOUNDRY-SENTINEL.md) (sentinel-AI consumes these records for attribution), and [PERFORMANCE-HARNESS-FRAMEWORK.md](PERFORMANCE-HARNESS-FRAMEWORK.md) (replay harnesses are a category there).
+
+## Why This Doc Exists
+
+The substrate has shipped end-to-end in Rust over the last 48 hours: governor, working-set-manager, demand-aligned-recall, audit-recorder, check_redundancy oxidation. ~25+ PRs of substrate work in canary.
+
+**None of it has been validated against production traffic.** The TurnReplayRecord type exists; no production turn has been recorded. The chat-roundtrip-live-harness exists; it consumes `RuntimeFrame::synthetic_chat("hello")` — a synthetic fixture, not a captured real turn. Tests pass; demos work; whether the substrate behaves correctly on what real personas actually do under real load — **we don't know.** That's the gap.
+
+> *"these guys always rig up"* — Joel naming the failure mode: a working demo that doesn't survive contact with production. This document specifies the loop that closes it.
+
+The architectural answer is a **production-recording → deterministic-replay → bit-equal-validation** loop, where every persona turn in production:
+
+1. **Produces a signed `TurnReplayRecord`** with cryptographic provenance + full input/output state.
+2. **Lands in a tamper-evident archive** that survives substrate restarts.
+3. **Can be replayed** against the current substrate code with deterministic-identical output, or fails loud with a typed `ReplayDivergence`.
+4. **Is consumed by sentinel-AI** for outcome attribution + the validation harnesses for regression detection.
+
+If any of those four steps is missing, we don't have "100% Rust cognition with proof." We have substrate-shaped scaffolding.
+
+## The Four Substrate-Enforced Properties
+
+Production replay is structural. It is not a "QA process." It is a property the substrate proves for every turn:
+
+### Property 1 — Every Turn Produces A Signed TurnReplayRecord
+
+The persona-cognition module's `handle_frame` returns only after the substrate has signed + persisted a `TurnReplayRecord` for that turn. Per `PERSONA-COGNITION-CONTRACT.md` §"Core Surfaces" → §"`TurnReplayRecord`":
+
+```rust
+pub struct TurnReplayRecord {
+    pub turn_id:           TurnId,
+    pub persona:           PersonaId,
+    pub frame:             Arc<RuntimeFrame>,
+    pub assembly:          WorkingMemoryAssemblySnapshot,
+    pub recall_trace:      RecallTrace,
+    pub lease:             CognitionLeaseSnapshot,
+    pub composition:       CompositionPlanSnapshot,
+    pub decision:          PersonaDecision,
+    pub output:            Option<RenderedOutput>,
+    pub timing:            TurnTiming,
+    pub resource_usage:    ResourceUsage,
+    pub provenance_chain:  Vec<ArtifactRef>,
+    pub signature:         TurnSignature,
+}
+```
+
+**Substrate enforces this by type.** The `persona-cognition` module's `handle_frame` returns `ModuleResult::Ok` only after the record is signed and the signature verified. A turn that fails to produce a record fails the substrate's invariant test — it is a substrate bug, not an optional feature.
+
+### Property 2 — Records Persist To A Tamper-Evident Archive
+
+Records land in `~/.continuum/replay/<turn_date>/<turn_id>.jsonl` as one signed line per turn. The directory rolls daily. The substrate's `replay-archive` module owns:
+
+- Append-only write semantics (same shape as audit-recorder #1344).
+- Per-turn signature verified at write time and again at read time.
+- A chain-hash linking turns in temporal order so a missing turn is detectable.
+
+Records are persona-private by default — only the producing persona's identity can read its own records. Federation (cross-instance sharing of replay records) requires explicit consent + provenance, same shape as sentinel artifact sharing in `GENOME-FOUNDRY-SENTINEL.md` §10.
+
+### Property 3 — Deterministic Replay Against Current Substrate
+
+A `cargo replay <turn_id>` invocation:
+
+1. Loads the record from the archive.
+2. Reconstructs the substrate state needed for replay: composition pinned, recall index snapshotted, governor policy at the record's `policy_version`, persona's `IdentityStateSnapshot` restored.
+3. Re-runs the persona-cognition module against the recorded `RuntimeFrame`.
+4. Produces a *new* `TurnReplayRecord` from the replay.
+5. Compares structured fields bit-equal against the original.
+
+```rust
+// PROPOSED — core/continuum-core/src/cognition/replay/mod.rs
+pub trait CognitionReplayer: Send + Sync {
+    /// Replay a recorded turn deterministically. Returns the replayed
+    /// record; comparison is the caller's job (the harness layer).
+    async fn replay(&self, record: &TurnReplayRecord) -> Result<TurnReplayRecord, ReplayError>;
+
+    /// Verify a record's signature + provenance chain. Pure function.
+    fn verify(&self, record: &TurnReplayRecord) -> Result<VerifiedRecord, VerificationError>;
+
+    /// Bit-equal field comparison. Returns a typed diff when they
+    /// don't match — the diff IS the bug report.
+    fn diff(&self, original: &TurnReplayRecord, replayed: &TurnReplayRecord) -> ReplayComparison;
+}
+
+pub enum ReplayComparison {
+    BitEqual,
+    Divergence { fields: Vec<DivergedField>, severity: ReplaySeverity },
+}
+
+pub enum ReplaySeverity {
+    /// Output differs but the decision is the same and the substrate
+    /// can prove the difference is bounded reprojection (e.g. recall
+    /// scored slightly different on a non-determined tiebreak). Logged,
+    /// not failed.
+    BoundedNonDeterminism,
+    /// Output differs in a way that crosses a decision boundary
+    /// (Speak vs Decline, or different addressee). FAILS the replay
+    /// harness; PR cannot merge without explanation.
+    DecisionBoundaryCrossed,
+    /// Substrate state mismatch (governor policy version, working set
+    /// composition, etc.) — environmental drift, not a cognition bug.
+    /// Logged + flagged; harness rerun after substrate stabilizes.
+    SubstrateStateDrift,
+}
+```
+
+### Property 4 — Sentinel + Harnesses Consume Records From Prod, Not Synthetic
+
+Two downstream consumers are explicitly bound to the replay archive:
+
+- **Sentinel-AI's attribution loop** (per `GENOME-FOUNDRY-SENTINEL.md` Part 6) reads from `~/.continuum/replay/`. It does not consume synthetic test fixtures. If the replay archive is empty, sentinel has nothing to attribute and emits a typed `NoTracesYet` signal — explicit, not silent.
+- **Validation harnesses** (per `PERFORMANCE-HARNESS-FRAMEWORK.md`) have a Tier-1 entry `prod-replay-harness` that consumes a directory of captured records and asserts bit-equal reproduction. The harness fails the PR if any record's replay produces a `DecisionBoundaryCrossed` divergence.
+
+`prod-replay-harness` is what closes the "POC vs PROD" gap. The chat-roundtrip-live-harness from #1348 uses synthetic frames because nothing else existed yet. `prod-replay-harness` uses real captured records. Both ship; both are Tier 1; the prod one is the load-bearing acceptance gate.

+
+Every step typed. Every transition observable. Every divergence has a named severity that the substrate enforces — never a silent "looks close enough."
+
+## Capture Discipline
+
+The capture side has rules the substrate enforces structurally, not by convention:
+
+1. **No synthetic-fixture path produces TurnReplayRecord.** Test scaffolds may construct `RuntimeFrame::synthetic_*()` fixtures, but the `persona-cognition` module produces signed `TurnReplayRecord`s ONLY when invoked in the production module-loop. Synthetic-test runs do not write to `~/.continuum/replay/`. This prevents the failure mode where the archive fills with synthetic records and replay-harness "passes" against fake data.
+
+2. **Sampling is configurable but defaults to 100%.** Production environments capture every turn. High-volume deployments may sample (e.g. 1-in-10) via governor policy; the sampling decision is itself a substrate-recorded event. Per-persona consent applies; a persona can opt out of capture entirely, in which case its turns produce no records and replay-harness skips them with an explicit `NotCaptured` entry.
+
+3. **Privacy isolation is structural.** A persona's records are persona-private by default. Cross-persona read requires explicit consent (same shape as engram sharing in `PERSONA-COGNITION-CONTRACT.md` §"Compartmentalization"). Sentinel-AI has training-input consent on by default but can be revoked per-persona without breaking the rest of the loop.
+
+4. **Records are content-addressable.** `turn_id` is the content hash of `(persona, frame_id, signature)`. Two captures of the same logical turn (e.g. from a federation peer replaying) collide deterministically — no duplicates, no silent overwrites.
+
+## Replay Discipline
+
+The replay side similarly enforces:
+
+1. **Substrate-state reconstruction is faithful or refused.** Replay must reconstruct: governor policy at `record.policy_version`, working-set tier sizes per the recorded `cascade_step`, composition pinning per `record.composition`. If the policy_version is unknown to the local substrate (e.g. the production substrate was on a policy revision local doesn't have), replay returns `ReplayError::PolicyVersionUnknown` — never proceeds with a substituted policy.
+
+2. **Recall index is snapshotted, not regenerated.** The recall trace in the record names the artifacts that scored above threshold at production time, with their scores. Replay loads the same artifacts (by content hash) — if any have been retired in the meantime, replay returns `ReplayError::ArtifactRetired { artifact, retired_at }` with the audit trail. This catches the failure where "replay passes" only because the substrate has evolved away from the original state.
+
+3. **Determinism boundaries are named.** Some sources of non-determinism are intrinsic to the substrate (parallel embedding generation order, tie-breaking when recall scores match). The replay comparison knows about these and admits `BoundedNonDeterminism` for the documented set — but ANY deviation outside that set is `DecisionBoundaryCrossed` or worse.
+
+4. **Replay is the inverse of capture in cost.** Capture is sub-ms (signing + append). Replay is bounded by the original inference cost; a 5-second cloud LLM turn replays in roughly the same wall-clock. Validation harnesses bound their run by either a turn count (N=100 records) or a wall-clock budget (30 minutes), not by "all of them," so the prod-replay-harness is feasible to run on every PR.
+
+## Acceptance Criteria
+
+The prod-cognition-replay loop is "done" when the following are provable on canary, with PR-attached evidence:
+
+**Capture side:**
+
+- `persona-cognition` module produces signed `TurnReplayRecord` for every turn invoked through the production path. Verified by a regression test that asserts: N synthetic turns produce 0 records (synthetic path is dead); N production-path turns produce N records.
+- `~/.continuum/replay/<date>/*.jsonl` exists, append-only, with chain-hash linking.
+- Cross-persona read attempt returns `AccessDenied` with audit trail.
+
+**Replay side:**
+
+- A `cargo replay <turn_id>` invocation reproduces the original record bit-equal in the structured-fields domain (the `decision` variant + `output` text + `recall_trace` artifact set + `composition` LoRA stack + `provenance_chain`).
+- A tampered record's signature fails `verify` with typed reason.
+- A record referencing a retired artifact returns `ArtifactRetired` not a silent substitution.
+
+**End-to-end validation:**
+
+- `prod-replay-harness` is added to `PERFORMANCE-HARNESS-FRAMEWORK.md` as Tier 1. Each PR-relevant Rust change runs the harness against a baseline set of N captured production records. Any `DecisionBoundaryCrossed` divergence fails the PR.
+
+**Sentinel integration:**
+
+- Sentinel-AI reads from the replay archive (not from synthetic fixtures). Demonstrated by a smoke test that empties the archive and observes sentinel emitting `NoTracesYet`; populating the archive then observing sentinel begin attribution within one consolidation cycle.
+
+## Why This Earns Its Space
+
+A 25-PR substrate landing is impressive volume but it's substrate scaffolding. Without prod-replay, every claim about the substrate's behavior is "the tests say so." With prod-replay:
+
+- A persona that drifted in production this week is reproducible on a developer's machine bit-for-bit, deterministically, in seconds.
+- Sentinel-AI's "refined LoRA layer X improved outcomes" claim is checkable against real turn-by-turn evidence, not a synthetic benchmark.
+- A regression that ships to canary trips the replay-harness before it can poison main.
+- The validation gap that calls *"these guys always rig up"* a fair characterization is closed by structural enforcement, not by adding QA process.
+
+This is what 100% Rust cognition + proof it works looks like as substrate, not as audit findings: the substrate produces the evidence on every turn, the substrate stores the evidence safely, the substrate replays the evidence on demand, the substrate fails loud when replay diverges. No human in the loop until a divergence fires.
+
+## Open Questions
+
+1. **Sampling under high load.** Default 100% capture is correct in development; in a high-volume deployment (1000+ turns/min/persona) the archive's I/O cost matters. Tentative: governor sets a sampling rate per cascade step; under cascade 0, 100% capture; under cascade 2+, sample 1-in-10 with explicit `Sampled` markers in the records that did capture so replay-harness skips the missing ones with audit, not silently.
+
+2. **Replay archive size growth.** A persona doing 100 turns/day for a year produces ~36,000 records. JSONL with full RuntimeFrame snapshots is on the order of 1-10 KB per record → ~36-360 MB/persona/year. Tentative: roll daily; archive month-old days to `replay-cold/` with content-hash dedup; never delete (records are evidence; deletion is a substrate operation that emits its own audit record).
+
+3. **Cross-substrate-version replay.** A record produced on substrate v1.0 replayed against substrate v2.0 — how do we tell the difference between "substrate genuinely diverged" and "v1.0 was correct, v2.0 is the bug"? Tentative: the record's `policy_version` includes the substrate's git commit at capture time; replay carries that as a flag; the replay-harness's `SubstrateStateDrift` severity is what surfaces it. A human reads the divergence and decides.
+
+4. **Capture during sentinel refinement passes.** Sentinel produces a new artifact mid-day; the next persona turn uses it. The replay record names the artifact by content hash. A week later sentinel publishes another refinement supersedng it. Does replay use the old hash (which still exists, archived) or the latest? Tentative: replay always uses the exact hash named in the record. If sentinel retired the old artifact, replay surfaces `ArtifactRetired` with the retirement timestamp and the user decides whether to pull the cold copy from archive.
+
+5. **Federated replay-records.** A peer instance produces records; can our instance replay them locally? Tentative: yes, but only if the producing peer's signed substrate version is in our compatible-version set. Replay across substrate variants needs explicit substrate-compat-class declaration (out of scope for v1).
+
+6. **The "always rig up" failure mode the substrate must structurally prevent.** Joel called this out: implementers ship a working demo that doesn't survive production. The substrate's structural answer: synthetic-fixture path produces 0 records → replay-harness has no fake data to "pass" against → "looks good in demo" cannot be confused for "works in prod." But that depends on the synthetic-fixture path actually being disconnected from the record-write path. Tentative test: build a synthetic chat turn through every test scaffold; assert the replay archive is empty after. Failing this test means a synthetic-record leak that would re-open the gap.

+# RTOS Debugger Probes — JTAG for the Persona Substrate
+
+## What this is
+
+The substrate is concurrent: per-persona service loops, the shared-analysis single-flight cache, the inference adapter pool, the airc subscription stream, the hippocampus admission + recall + decay tick — all running as independent tokio tasks. `println!` and `tracing::info!` lines are unstructured drudgery in distributed code: you can't filter them, you can't replay them, and "what was the persona's prompt when it produced that response" is a manual grep across thousands of lines.
+
+The **probe macros** are the substrate's RTOS debugger:
+
+- `probe!(class = "...", field = val, ...)` — a non-blocking breakpoint. Snapshots the named variables at the call site, routes by `class` to subscribers + a disk log.
+- `time_sync!("phase_name", { ... })` — RAII timing for a synchronous block. The wrapped block's duration becomes a timing probe at scope exit.
+- `time_probe!("phase_name", future)` — substrate-tracing timing for an async future. Safe-by-construction (`.instrument(span).await` shape — no `_enter` guard held across `.await`). Emits to the same `timing` probe class as `time_sync!`, so operators see sync + async timings on one flat timeline. Prefer this over the bare `.instrument(info_span!(...))` form when sprinkling async timings — the verbose form gets skipped when adding probes in a hurry.
+- `time_async!("category", "operation", future)` — RAII timing for an async future via `crate::logging::TimingGuard`. Different shape from `time_probe!` (logging crate's own logger vs substrate probe stream). Use `time_probe!` for cognition / substrate timing; use `time_async!` for the legacy logging-crate-bound timing.
+- `stack!()` — the URI ancestry at this point: which dispatched command's context are we in.
+
+Each probe call is **one line at the seam**. Easy enough to add that the cognition code grows probes the way it grows lines — that's the only way debugging concurrent code stays sustainable. Per Joel 2026-06-06: "Easy one liners or it won't happen."
+
+## When to add a probe
+
+Treat every probe call as a **debug breakpoint you wanted to set**. If your future self (or another persona reviewing the code) would want to know "what were the surrounding variables at this point" — that's a probe. The class names the *seam* (where in the cognition flow), the fields name *what mattered at the breakpoint*.
+
+Add a probe at every:
+
+- **Branch boundary** — cache hit vs miss, success vs error, silence vs speech, gate passed vs rejected.
+- **Stage entry / exit** — analyze entry, analyze exit (with parsed result), respond entry, respond exit (with PersonaResponse decision).
+- **External call** — before + after each LLM inference, RAG composition, airc publish.
+- **State seam** — the moment a value crosses a module boundary (prompt assembled → passed to inference; analysis returned → passed to scoring).
+- **Decision point** — anywhere the brain CHOSE something (which adapter, which engrams to recall, whether to admit).
+
+DO NOT add a probe for:
+
+- Prose log lines a human reads in a console (use `tracing::info!`).
+- High-frequency hot-path data (use the `RagCaptureSink` pattern for budgeted-capture instead).
+
+## Class taxonomy
+
+A stable set of `class` values so probes from different files compose into a coherent story. Defined as constants in `persona::probes` and `cognition::probes` (next slice).
+
+**Persona service loop** (`persona/service_loop.rs`):
+- `persona.turn.start` — turn entry: persona_id, room_id, lamport, message_text length
+- `persona.turn.recall` — engrams pulled from L2: count, ids, scores
+- `persona.turn.admit` — admission write outcome: success/error, engram_id
+- `persona.turn.compose` — RAG composition output: sources delivered, total budget used
+- `persona.turn.silent` — persona chose silence: reason from `PersonaResponse::Silent`
+- `persona.turn.spoke` — persona produced a reply: response text length, model_used
+- `persona.turn.error` — turn failed: error message + which stage
+
+**Persona response cycle** (`persona/response.rs`):
+- `persona.response.enter` — respond() entry: input fingerprint
+- `persona.response.analyze.cache` — single-flight cache hit / miss / single-persona-noop
+- `persona.response.render.prompt` — assembled prompt: system_prompt length, history count, matched_angle present, engrams count, social_signals present
+- `persona.response.render.raw` — raw LLM output: text length, model_used, finish_reason
+- `persona.response.render.parsed` — post-processed: silent vs spoke + reason
+- `persona.response.exit` — final PersonaResponse: decision, text length
+
+**Prompt assembly** (`persona/prompt_assembly.rs`):
+- `persona.prompt.assemble` — final composition stats: persona, system_message_len, message_count, estimated_tokens, matched_angle_present, engrams_count, social_signals_present, voice_mode, multi_party_strategy
+
+**Inference adapter** (`inference/llamacpp_adapter.rs::generate_text`):
+- `inference.generate.enter` — adapter received request: model, persona_id, msg_count, max_tokens, has_system_prompt, parts_image, parts_audio
+- `inference.generate.exit` — adapter returning: model, tokens_out, text_len, duration_ms, tok_per_sec
+- Timing seams (emit on the `timing` class with `seam` field):
+  - `inference.render_chat` — synchronous chat-template rendering (sub-ms typically, but cumulative)
+  - `inference.forward.text` — pure-text LLM forward pass through the scheduler (the dominant cost on LCD tier — 95%+)
+  - `inference.forward.multimodal` — mtmd single-flight path (text+image / text+audio)
+
+**Cognition: shared analysis** (`cognition/shared_analysis/mod.rs`):
+- `cognition.analyze.enter` — input fingerprint, known_specialties count
+- `cognition.analyze.noop_single_specialty` — short-circuit fired
+- `cognition.analyze.cache_hit` — single-flight cache returned a prior result
+- `cognition.analyze.inference` — LLM call: model_used, duration_ms
+- `cognition.analyze.parse` — parsed angles: per-specialty present/empty
+- `cognition.analyze.error` — typed AnalysisError variant
+
+**Timing** (any seam):
+- `timing` — emitted by `time_sync!` and `time_probe!` spans. Field `seam` = the seam identifier (the macro's first argument). Field `duration_ms` = wall-clock duration from span creation to span close.
+
+  > **Field-naming convention**: timing spans MUST use `seam = $name`, NOT `name = $name`. The `name` field collides with both `info_span!`'s built-in span name slot AND with `probe!(class = "state", name = ...)` payloads. `seam` (the noun for "where in the cognition flow this measurement happens") is unique and `jq`-able: `.fields.seam == "cognition.analyze"` matches either macro and never collides with event-shape probes. Convention pinned by PR #1541 review.
+
+**General-purpose** (when no taxonomy fits yet, document the intent in the docstring above the probe):
+- `decision` — branch was taken with reason
+- `state` — value snapshot at this point
+- `error` — exception path
+
+## How to enable + read
+
+### Enable file capture
+
+Two environment variables — no recompile, no config file:
+
+```bash
+# Capture every persona.* probe + every cognition.* probe to disk
+export CONTINUUM_PROBE_DIR=/tmp/continuum-probes.jsonl
+export CONTINUUM_PROBE_CLASSES=persona,cognition
+
+# Or capture EVERYTHING (the firehose):
+export CONTINUUM_PROBE_CLASSES=*
+
+# Or mix exact classes with namespace prefixes:
+export CONTINUUM_PROBE_CLASSES=cognition.analyze.parse,persona.turn,timing
+```
+
+- `CONTINUUM_PROBE_DIR` (path) — append-only JSONL log. Unset = file sink absent. Directory must exist; the sink errors loudly if not (no silent drop per `[[no-fallbacks-ever]]`).
+- `CONTINUUM_PROBE_CLASSES` (comma-separated) — class filter. Each value is matched against each probe's `class` by one of three rules (same convention as `tracing_subscriber`'s `RUST_LOG`):
+
+  1. **`*`** — wildcard; matches every class. Use to capture the firehose and filter offline with `jq`.
+  2. **Exact match** — `cognition.analyze.parse` matches only that one class.
+  3. **Namespace prefix** — `persona` matches `persona.turn.spoke`, `persona.response.enter`, every `persona.*`. Implementation: `class == filter || class.starts_with(filter + ".")` — the `.` guard prevents `persona` from accidentally matching `personality.x`.
+
+  Empty / unset = no filter configured, every class passes. `*` is the explicit "capture all" intent per `[[no-fallbacks-ever]]`.
+
+The sink is installed at process startup by `routing::install_probe_tracing(config)`, which composes `UriCaptureLayer` (URI ancestry) + `ProbeRouterLayer` (in-process broadcast) + `JsonlProbeFileSink` (disk, when `config.probe_file` is set) + a fmt layer governed by `RUST_LOG` — all in one call.
+
+The installer takes a typed `ProbeTracingConfig { probe_file, probe_classes, default_filter }` — NOT env vars directly. Env coupling lives at exactly one seam: `ProbeTracingConfig::from_env(default_filter)`. This keeps the library function parallel-test-safe (no `std::env::set_var` racing under `cargo test`) and puts every config source (env, file, CLI flags, hardcoded) on equal footing.
+
+`continuum-core-server`'s `main()` calls `install_probe_tracing(ProbeTracingConfig::from_env("info"))?`. Tests / demos that want a clean per-call probe stack construct `ProbeTracingConfig` directly and pass a tmpdir path — no env mutation, no flakes. The install is idempotent via `try_init` so re-init from multiple sites is safe. When `config.probe_file` is set, the server prints `probes landing at <path>` at boot so the operator sees the env var took effect.
+
+### Read
+
+Each line is JSONL with this shape:
+
+```jsonl
+{"captured_at_ms":1717689000123,"class":"persona.response.render.prompt","uri_chain":["airc:///cognition/respond"],"message":"assembled","fields":{"persona":"Paige","system_prompt_len":"824","history_count":"5","matched_angle":"true","engrams_count":"3"}}
+```
+
+`tail -f` works because the sink flushes per line. Standard `jq` queries:
+
+```bash
+# Every probe Paige fired this run, in chronological order
+jq -c 'select(.fields.persona == "Paige")' /tmp/continuum-probes.jsonl
+
+# Every turn that ended in silence + the reason
+jq -c 'select(.class == "persona.turn.silent") | {persona: .fields.persona, reason: .fields.reason}' \
+  /tmp/continuum-probes.jsonl
+
+# Find slow stages — every timing probe over 500ms
+jq -c 'select(.class == "timing" and (.fields.duration_ms | tonumber) > 500)' \
+  /tmp/continuum-probes.jsonl
+
+# Reconstruct a single turn: filter on lamport
+jq -c 'select(.fields.lamport == "42")' /tmp/continuum-probes.jsonl
+```
+
+For bottleneck hunting, the `timing` class + `name` field give you a flat timeline of every instrumented block in the run.
+
+## How to add a probe
+
+```rust
+use crate::probe;
+
+// At a branch boundary:
+if some_condition {
+    probe!(
+        class = "persona.response.render.prompt",
+        persona = %ctx.identity.agent_name,
+        system_prompt_len = assembled.system_message.len(),
+        history_count = history.len(),
+        matched_angle = !matched_angle.is_empty(),
+        engrams_count = recalled.len(),
+        "assembled"
+    );
+    // ... continue normally
+}
+
+// At a stage exit:
+probe!(
+    class = "persona.turn.spoke",
+    persona = %ctx.identity.agent_name,
+    response_len = response_text.len(),
+    model_used = %model_used,
+    duration_ms = elapsed,
+);
+
+// Around a timing-critical block (sync):
+let result = time_sync!("recall_l2", {
+    cognition.admission.recall_scored(now_ms, 8)
+});
+
+// Around a timing-critical future (async, substrate probe stream):
+let analysis = time_probe!("cognition.analyze", analyze(input));
+let response = time_probe!("inference.generate", adapter.generate_text(req));
+
+// Around a timing-critical future (logging-crate RAII shape — legacy):
+let analysis = time_async!("cognition", "analyze", analyze(input));
+```
+
+Both async forms exist for historical reasons: `time_probe!` is the
+substrate's tracing-span shape (composes with `ProbeRouterLayer` +
+`JsonlProbeFileSink`); `time_async!` is the `crate::logging`'s RAII
+TimingGuard shape (logs to the logging crate's own logger). For new
+cognition seams prefer `time_probe!` — that's what the rest of the
+probe pipeline consumes.
+
+> **Persistence caveat:** `time_sync!` and `time_probe!` emit
+> tracing SPANS, not events. The current `ProbeRouterLayer` and
+> `JsonlProbeFileSink` only implement `on_event` — they do NOT yet
+> capture span-close events. Task #196 wires the missing
+> `on_close` so timing spans persist to the JSONL log; until then,
+> the timing macros work for `tracing`-native consumers (e.g.
+> `tracing_subscriber::fmt`) but timings won't appear in the JTAG
+> probe log. The macro lands here so the call shape is stable
+> when the routing side ships.
+
+### Convention rules
+
+1. **Class is a noun-phrase path** — `persona.turn.silent`, not `personaTurnSilent` or `silent`. Use dots to express hierarchy.
+2. **Fields are named like local variables** — `persona`, `prompt_len`, `decision` — short, specific, plural-when-collection. Avoid CamelCase.
+3. **Use `%` for Display, `?` for Debug** — `persona = %ctx.identity.agent_name` (Display), `decision = ?response` (Debug). The recorder visits use both.
+4. **Number fields are numbers** — `prompt_len = s.len()` (not `prompt_len = s.len().to_string()`). The visitor handles numeric types natively.
+5. **The trailing string is the message** — `"assembled"`, `"declined"`, `"falling back"` — one phrase that explains what happened at this point. Optional; skip when fields are self-evident.
+6. **Don't probe in tight loops without sampling** — per-engram-recall is fine, per-token is not. Probes are non-blocking but the visitor allocates a HashMap per event.
+
+### When you add a probe, update this manual
+
+Append the new `class` to the taxonomy section above. Stable class names are the substrate's debugger's API — if it isn't in the taxonomy, nobody knows it exists. The manual is the source of truth.
+
+## Where the work must be done
+
+The infrastructure exists (Slice P, #176/#177): `routing/macros.rs` (macros), `routing/probe_router.rs` (broadcast layer), `modules/probe_stream.rs` (URI consumer), `routing/probe_file_sink.rs` (JSONL persistence — added by this slice).
+
+What is INCOMPLETE — the sprinkle that turns the JTAG hardware into a working debugger:
+
+- [x] `persona/response.rs::respond_inner` — entry, analyze result, raw LLM output (full text), exit-spoke
+- [x] `persona/response.rs::run_render` — assembled prompt verbatim + composition stats
+- [x] `cognition/shared_analysis/mod.rs::analyze` — entry, single-specialty noop, L1 cache hit, parsed angles (empty vs non-empty count)
+- [x] `persona/service_loop.rs::serve_persona_loop_inner` — `turn.start` / `turn.spoke` (with full phase decomposition recall+admit+compose+respond+say) / `turn.silent` (with reason) / `turn.error` (with stage=respond|say) — **wired in this PR**
+- [x] `persona/prompt_assembly.rs::assemble` — final composition stats wired at the function tail (system_message_len, message_count, estimated_tokens, matched_angle_present, engrams_count, social_signals_present, voice_mode, multi_party_strategy)
+- [ ] `cognition/response_orchestrator.rs::score_persona` — per-persona score + matched_angles + decision reason — note: the score_persona gate is currently bypassed (response.rs:288–300); probes go in if/when it's re-wired
+- [x] `inference/llamacpp_adapter.rs::generate_text` — entry probe (`inference.generate.enter`) + timing probes around `render_chat` and the two `forward.*` spawn_blocking paths + exit probe (`inference.generate.exit`) carrying `tok_per_sec`. This is the dominant-cost seam on LCD tier per the inference-latency campaign (task #195).
+
+Each gets a small commit that adds the probes + updates this manual's checklist. The proof-of-value for each commit: enable the file sink, run the multi-persona scenario, `jq` the relevant class, see the variable snapshots.
+
+## Doctrine
+
+- `[[jtag-probes-are-rtos-debugger]]` — probes ARE the breakpoints. Sprinkle at every meaningful seam. Name the surrounding vars. Easy one-liners or it won't happen.
+- `[[observability-is-half-the-architecture]]` — CaptureSink + Noop default + replay-as-first-class. The file sink follows this pattern.
+- `[[no-fallbacks-ever]]` — the sink errors loudly if its configured path is unwritable. No silent drop.
+- `[[init-once-handle-then-lease-zero-copy-refs]]` — probe macros expand to `tracing::event!` which inherits tracing's `release_max_level_*` compile-time gates. Zero cost when off at build time.
+- `[[no-rust-gates-around-cognition]]` — probes observe the cognition, they DO NOT decide for it. A probe never changes flow; it only records.

+# Sensory Model And Experiential Plasticity Plan
+
+**Status**: active alpha plan
+**Updated**: 2026-05-11
+**Owner split**: Codex/Mac owns literature and candidate metadata; Windows/RTX
+owns empirical build, forge, CUDA/Vulkan VDD.
+**Parent**: [Alpha Gap Analysis](../planning/ALPHA-GAP-ANALYSIS.md)
+**Related**: [Persona-as-Rust-Library](PERSONA-AS-RUST-LIBRARY-PLAN.md),
+[Restore Full Sensory Parity](../infrastructure/RESTORE-FULL-PARITY-PLAN.md),
+[Genome Architecture](../genome/GENOME-ARCHITECTURE.md)
+
+## Thesis
+
+Continuum personas are sensory entities, not text bots. The standard local
+persona contract requires text, vision/image/video perception, audio input,
+voice/audio output, avatar/control output, WebRTC presence, and traceable
+runtime behavior. The model layer must therefore select or forge models by
+capability and hardware budget, not by scattered hardcoded model names.
+
+The target architecture is:
+
+```text
+Persona sensory requirement
+  -> Rust ModelRequirement
+  -> Rust registry/admission resolver
+  -> vetted model artifact or forge task
+  -> llama.cpp local runtime path
+  -> VDD timing/resource report
+  -> canary promotion
+```
+
+No runtime code should know a specific model name because a persona wants
+sensory cognition. Runtime code asks for capabilities, context, intelligence,
+license/runtime constraints, and hardware budgets. The registry resolves the
+best vetted artifact on the current machine.
+
+## Current Public Model Read
+
+This section is a candidate scout, not the runtime source of truth. Runtime
+truth belongs in the Rust registry once artifacts are validated.
+
+### Qwen2.5-Omni-7B
+
+- **Source**: [Qwen/Qwen2.5-Omni-7B](https://huggingface.co/Qwen/Qwen2.5-Omni-7B)
+- **GGUF**: [ggml-org/Qwen2.5-Omni-7B-GGUF](https://huggingface.co/ggml-org/Qwen2.5-Omni-7B-GGUF)
+- **Current read**: official end-to-end omni model with a working ggml-org
+  GGUF path for local text, image, and audio input through upstream llama.cpp.
+  RTX 5090 VDD on 2026-05-11 validated Q4_K_M plus mmproj-f16 on CUDA sm_120:
+  text bench, image description, and audio transcription all passed.
+- **Measured RTX 5090 result**: upstream llama.cpp `1ec7ba0`,
+  `-DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=120-real`,
+  `Qwen2.5-Omni-7B-Q4_K_M.gguf` 4.36 GiB plus `mmproj` 2.5 GiB. Text bench
+  `-ngl 99 -p 512 -n 128 -r 3`: pp512 13,659 t/s, tg128 220 t/s. Vision
+  smoke: 1,288 px cat image described correctly, text generation 212 t/s.
+  Audio smoke: JFK WAV transcribed correctly, text generation 216 t/s.
+- **Known kernel gap**: upstream llama.cpp reported CUDA `POOL_1D` unsupported
+  inside the CLIP/mmproj graph, so that operator falls back from CUDA to CPU.
+  Decode stayed on CUDA; the fallback is still a VDD failure to track and fix,
+  not an acceptable steady-state architecture. Upstream tracking referenced by
+  RTX VDD: ggml-org/llama.cpp PR 16837, comment 3461676118.
+- **Alpha role**: recommended full-tier local sensory-input candidate for
+  Blackwell/RTX-class hosts now. It closes text/image/audio input locally and
+  is fast enough to restore real persona perception. It still does not close
+  speech output unless llama.cpp support grows, we pair a typed voice-output
+  adapter, or we forge the missing output path.
+- **Registry action**: add as the first vetted full-tier candidate with a
+  `requiresAccelerator=true` profile and a `mmproj_pool_1d_cpu_fallback`
+  warning until the upstream kernel is fixed. Mac Metal still requires its own
+  VDD because this result is CUDA/Blackwell-specific.
+
+### Qwen2.5-Omni-3B
+
+- **GGUF**: [ggml-org/Qwen2.5-Omni-3B-GGUF](https://huggingface.co/ggml-org/Qwen2.5-Omni-3B-GGUF)
+- **Current read**: smaller Qwen2.5-Omni GGUF candidate for low-memory hosts.
+  Needs confirmation that llama.cpp support covers the same sensory path as 7B.
+- **Alpha role**: MBA/low-memory sensory candidate if it passes audio/vision
+  VDD.
+- **Registry action**: bench after 7B. If audio output is transformers-only or
+  incomplete in llama.cpp, treat as compatibility candidate, not alpha sensory
+  default.
+
+### Qwen3-Omni-30B-A3B-Instruct
+
+- **Source**: [Qwen/Qwen3-Omni-30B-A3B-Instruct](https://huggingface.co/Qwen/Qwen3-Omni-30B-A3B-Instruct)
+- **GGUF**: [ggml-org/Qwen3-Omni-30B-A3B-Instruct-GGUF](https://huggingface.co/ggml-org/Qwen3-Omni-30B-A3B-Instruct-GGUF)
+- **Current read**: official Qwen3-Omni Any-to-Any MoE model. HF marks the
+  source model `text-to-audio`, `multimodal`, and `Any-to-Any`. The ggml-org
+  GGUF mirror has llama.cpp `-hf` examples.
+- **Alpha role**: Blackwell/5090 sensory flagship and future distributed/grid
+  target. This is the best current candidate for the complete sensory contract
+  if audio output works in local runtime. MoE makes it the best pruning/paging
+  target if VDD is viable.
+- **Registry action**: bench after Qwen2.5-Omni-7B input path. Validate
+  30B/3B-active behavior, speech output, context, VRAM, and whether MoE expert
+  paging/pruning can make it practical.
+
+### Qwen3.6-27B
+
+- **Source**: [Qwen/Qwen3.6-27B](https://huggingface.co/Qwen/Qwen3.6-27B)
+- **Current read**: official open-weight Qwen3.6 model. HF marks it
+  `Image-Text-to-Text`; model card says causal LM with vision encoder, 262K
+  native context, vLLM/SGLang/KTransformers support, and explicit image-input
+  examples.
+- **Alpha role**: high-end dense sensory reasoning target for 5090/3090-class
+  hosts if quantized runtime is viable.
+- **Registry action**: Windows/RTX must validate CUDA/Vulkan llama.cpp or other
+  local adapter path, quant size, projector handling, first-token, tok/s, CPU%,
+  GPU%, and VRAM.
+
+### Qwen3.6-35B-A3B
+
+- **Source**: [Qwen/Qwen3.6-35B-A3B](https://huggingface.co/Qwen/Qwen3.6-35B-A3B)
+- **GGUF probe**: [bartowski/Qwen_Qwen3.6-35B-A3B-GGUF](https://huggingface.co/bartowski/Qwen_Qwen3.6-35B-A3B-GGUF)
+- **Current read**: official open-weight Qwen3.6 sparse MoE/VLM. HF marks it
+  `Image-Text-to-Text`; card says 35B total / 3B active and causal LM with
+  vision encoder. The community GGUF has Q4_K_M around 21.39GB.
+- **Alpha role**: prime MoE pruning/paging target: high capability surface with
+  only part of the model active per token.
+- **Registry action**: validate the GGUF first, then decide whether to forge
+  official Continuum quants with embedded chat template and measured hardware
+  profiles.
+
+### Qwen3.5 VLMs
+
+- **Source**: [Qwen/Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B)
+- **Current read**: official Qwen3.5 models are `Image-Text-to-Text`; model
+  card says unified vision-language foundation and causal LM with vision
+  encoder.
+- **Alpha role**: current mid/full host VLM target if Qwen3.6 is too heavy or
+  less stable.
+- **Registry action**: existing Continuum forged 4B/code artifacts should be
+  rechecked against official Qwen3.5 VLM behavior, projector needs, and
+  prompt/template metadata.
+
+### Qwen3.5-Omni
+
+- **Source**: [paper](https://huggingface.co/papers/2604.15804)
+- **Current read**: public reports describe text/audio/image/video native omni
+  behavior, hundreds of billions of parameters, 256K context, and audio-visual
+  capabilities. Official downloadable weights were not confirmed in this pass.
+- **Alpha role**: watch item and API/closed-source comparison target.
+- **Registry action**: do not add runtime row until exact downloadable artifact
+  and license are verified.
+
+### Existing Qwen2-VL Baseline
+
+- **Source**: `Qwen/Qwen2-VL-7B-Instruct-GGUF`
+- **Current read**: already in `src/shared/models.json` with GGUF plus mmproj.
+- **Alpha role**: known working vision baseline and regression fixture.
+- **Registry action**: keep as baseline until Qwen3.5/3.6/Omni artifacts beat
+  it in VDD.
+
+Current ranking from AIRC/RTX scout and 2026-05-11 RTX VDD:
+
+1. `Qwen2.5-Omni-7B` official source plus `ggml-org` GGUF is the first full-tier
+   local sensory-input candidate. RTX 5090 VDD proved text, image, and audio
+   input with high throughput. It still needs speech-output validation or
+   forge/voice-adapter work, and the CUDA `POOL_1D` mmproj fallback must be
+   tracked as an upstream kernel gap.
+2. `Qwen3-Omni-30B-A3B-Instruct` plus `ggml-org` GGUF is the high-end
+   Blackwell/grid candidate, the likely complete sensory contract candidate,
+   and the best MoE pruning/paging target.
+3. `Qwen3.6-27B` and `Qwen3.6-35B-A3B` are valuable VLM/intelligence targets
+   but do not satisfy the full audio sensory contract alone. They need a paired
+   audio model or a forged Continuum sensory variant.
+
+## Forge-First Policy
+
+If the right sensory model does not exist in a clean, runnable, license-valid
+artifact, Continuum forges it. Missing GGUF, missing projector, missing audio
+layer, missing chat template, bad quant, bad kernel, or poor packaging is a
+foundry task, not an excuse to hardcode a weaker runtime path.
+
+This does not block getting a working model online. The alpha sequence is:
+
+1. admit the best already-working open model through the Rust registry;
+2. validate it with TDD/VDD on real hardware;
+3. keep the runtime capability-based so it can be replaced without code churn;
+4. forge, prune, defrag, quantize, and upstream the Continuum-optimized version;
+5. promote the forged model only when it beats the baseline on replay quality
+   and resource metrics.
+
+Working first and forging better second is different from accepting a fallback.
+The first working model is a measured baseline and service-restoration step.
+The forged model is the planned optimization path.
+
+Every forge, pruning, defrag, quantization, or kernel optimization pass must
+re-prove the full declared modality set. It is easy to optimize away video,
+image, audio-in, audio-out, or projector paths by accident. That is a failed
+candidate, even if text quality, size, or tokens/sec improved.
+
+The forge loop is:
+
+```text
+select official/open base
+  -> add or preserve required modality encoders/projectors
+  -> repair llama.cpp/GGUF/runtime support where needed
+  -> quantize for target hardware tiers
+  -> embed template/license/manifest metadata
+  -> publish under continuum-ai or approved registry
+  -> run TDD/VDD replay gates
+  -> admit through Rust registry
+```
+
+For Qwen3.5/3.6 this means we can produce Continuum-owned sensory variants:
+
+- `qwen3.6-35b-a3b-sensory-forged`: MoE/VLM target with measured expert
+  pruning and GPU profiles.
+- `qwen3.6-27b-sensory-forged`: dense high-quality sensory target.
+- `qwen2.5-omni-7b-continuum-gguf`: consumer full-sensory target if existing
+  community artifacts fail license/runtime gates.
+- `qwen3-omni-30b-a3b-blackwell-forged`: 5090/grid flagship if VDD shows it
+  can be made practical.
+
+## Experiential Plasticity
+
+Continuum should treat model selection as the starting point, not the end state.
+The `continuum-ai/experiential-plasticity-paper` card already states the core
+method: entropy-based pruning plus domain retraining can produce smaller
+models that improve on the target domain. Reported examples include Qwen3.5-4B
+improving on code and Qwen3.5-27B compressing substantially while improving on
+the target task. Source:
+[continuum-ai/experiential-plasticity-paper](https://huggingface.co/continuum-ai/experiential-plasticity-paper)
+
+In Continuum terms, experiential plasticity is the model foundry loop:
+
+```text
+capture real persona experience
+  -> score/replay/label by domain and modality
+  -> prune low-value weights/heads/experts
+  -> train or distill on the captured domain
+  -> defrag the resulting structure
+  -> quantize/package
+  -> validate against replay and VDD
+  -> admit as a new registry candidate
+```
+
+This applies to:
+
+- dense model pruning: remove low-utility heads/blocks for the target domain;
+- MoE pruning: remove or page cold experts, preserve hot experts, and measure
+  active-parameter quality rather than total-parameter marketing size;
+- modality pruning: keep every vision, video, audio-in, audio-out, projector,
+  tokenizer, and bridge path required by the persona contract; remove only
+  conversion paths that VDD proves are unused by that admitted profile;
+- LoRA/genome pruning: compact adapters after repeated experiential training;
+- KV/context policy: shorten or summarize context based on replay-proven value,
+  not arbitrary token limits.
+
+The important rule is that pruning is not "make it smaller and hope." Every
+cycle must be replayed against captured persona fixtures and measured against
+hardware telemetry. If it gets smaller but loses sensory accuracy, tool
+correctness, or persona responsiveness, it is not admitted.
+
+## Hardware Targeting
+
+The resolver must select by capability and pressure:
+
+| Host class | Backend target |
+| --- | --- |
+| Mac M-series | Metal + unified memory |
+| NVIDIA 3090/4090/5090 | CUDA first, Vulkan secondary |
+| AMD/Intel | Vulkan |
+| Low-memory hosts | GPU path if present; otherwise explicit degraded state |
+| Grid | Capability routing across machines |
+
+Default posture:
+
+- Mac M-series: prefer smaller Qwen3.5/3.6 VLM or Qwen2.5-Omni quants with
+  strict memory admission. Use unified memory pressure to gate context and
+  concurrent personas.
+- NVIDIA 3090/4090/5090: validate Qwen3.6-27B, Qwen3.6-35B-A3B, and
+  Qwen2.5/Qwen3 Omni. Highest priority for forge/alloy, MoE pruning, and VDD
+  timing.
+- AMD/Intel: treat Vulkan as a first-class local backend once validated. No CPU
+  happy path.
+- Low-memory hosts: admit smaller sensory or compatibility models. If sensory
+  cannot run, report `Unavailable`/`Degraded`, not fake success.
+- Grid: send sensory jobs to the host with the right GPU/artifact/residency
+  budget using command/grid contracts.
+
+The registry/admission result should explain:
+
+- selected model and artifact;
+- rejected candidates and reasons;
+- required files and whether they exist;

+
+## Windows/RTX Build Assignment
+
+Windows/RTX owns empirical proof for this workstream. The deliverable is not
+"looked at it"; it is a small VDD table per candidate:
+
+| Field | Required |
+| --- | --- |
+| HF repo and exact revision | yes |
+| Files pulled | yes |
+| License | yes |
+| Quant and size | yes |
+| Backend | CUDA and Vulkan where possible |
+| llama.cpp command or adapter path | yes |
+| First token latency | yes |
+| Decode tok/s | yes |
+| CPU utilization | yes |
+| GPU utilization | yes |
+| VRAM and RSS | yes |
+| Context length tested | yes |
+| Vision fixture result | yes |
+| Audio fixture result | yes for Omni/audio candidates |
+| Missing kernel/projector/audio layer | yes, if any |
+| Forge/alloy next step | yes, if not directly usable |
+
+Initial Windows/RTX queue:
+
+1. `Qwen/Qwen2.5-Omni-7B` official and `ggml-org` GGUF paths.
+2. `Qwen/Qwen3-Omni-30B-A3B-Instruct` feasibility on 5090-class hardware.
+3. `Qwen/Qwen3.6-27B` official + best available GGUF quant.
+4. `bartowski/Qwen_Qwen3.6-35B-A3B-GGUF` as a fast MoE/VLM probe.
+5. Existing `qwen2-vl-7b` as a baseline regression measurement.
+
+## Rust Registry Requirements
+
+The model registry needs typed vocabulary before any candidate becomes runtime
+default:
+
+- `ModelFamily`: `Qwen`, `ContinuumForged`, `Cloud`, etc.
+- `Architecture`: dense, MoE, omni, VLM, audio, embedding, reranker.
+- `Capability`: text, vision input, video input, audio input, audio output,
+  tool/control, avatar/control, embedding, LoRA, MoE.
+- `RuntimeBackend`: `LlamaCppLocal`, `CloudApi`, `ForgeTraining`,
+  `GridRemote`, with hardware backend nested below it.
+- `HardwareBackend`: `Metal`, `Cuda`, `Vulkan`, `Dmr`, `CpuDegraded`.
+- `ArtifactKind`: base GGUF/safetensors, mmproj, audio projector, tokenizer,
+  chat template, LoRA, adapter manifest, license, benchmark report.
+- `AdmissionState`: `Ready`, `NeedsDownload`, `NeedsForge`, `Unavailable`,
+  `Backpressured`, `KernelGap`, `LicenseBlocked`, `InsufficientMemory`.
+
+Selection must be capability/range based:
+
+```text
+needs:
+  family ~= qwen
+  intelligence >= full
+  context >= 64k
+  input includes text,image,audio
+  output includes text,audio
+  backend in cuda|metal|vulkan
+  memory <= host budget
+  license in allowed set
+```
+
+The registry may prefer Qwen, but it should not hardcode one model as the
+system truth. The current host and artifact state determine the admitted model.
+
+## TDD And VDD Gates
+
+TDD:
+
+- Rust unit tests for capability/range selection.
+- Missing artifact tests return `NeedsDownload` or `MissingArtifact`.
+- Missing projector tests reject false vision/audio capability.
+- License-blocked artifacts do not become defaults.
+- No candidate may be admitted if its chat template is unknown or unembedded.
+- No model row can use untyped provider/model strings in persona runtime paths.
+
+VDD:
+
+- `qwen2-vl-7b` baseline image fixture still works.
+- Qwen3.5/3.6 VLM candidate passes image/OCR/document fixtures.
+- Omni candidate passes text, image/OCR/document, short-video if declared,
+  audio-in, and speech-out fixtures.
+- Refined, forged, pruned, quantized, or kernel-optimized candidates rerun the
+  same modality fixtures before replacing the previous baseline.
+- Report first-token latency, tok/s, CPU%, GPU%, VRAM, RSS, context, and queue
+  wait for every candidate.
+- Run at least one replay-derived persona smoke: multiple messages consolidate
+  into one turn and the response does not echo prompt/RAG garbage.
+- CPU-only execution on GPU-capable hosts is a failing result unless the test is
+  explicitly a degraded-mode test.
+
+## PR Plan
+
+1. `docs/sensory-experiential-plasticity`: this document and alpha-plan link.
+2. `feature/rust-model-registry-candidates`: typed candidate metadata and
+   ts-rs exports; no runtime default switch yet.
+3. `feature/model-vdd-harness`: one Rust/CLI command emits the candidate VDD
+   table from structured timing/resource data.
+4. `feature/qwen36-vlm-admission`: admit Qwen3.6 VLM only after RTX/Mac
+   evidence exists.
+5. `feature/qwen-omni-admission`: admit Qwen2.5/Qwen3 Omni only after audio,
+   vision, and runtime support are proven.
+6. `feature/experiential-plasticity-foundry-loop`: capture -> prune/train ->
+   defrag -> quantize -> validate -> registry candidate.
+
+## Deletion Targets
+
+- duplicate model/provider lists outside the Rust registry;
+- stale compatibility/fallback code that silently picks another provider;
+- runtime references to unsupported local providers;
+- TS cognition model-routing logic;
+- comments or tombstones for deleted model paths;
+- candidate rows without evidence, license, or artifact ownership.

+# Shared Cognition Architecture
+
+> **One shared analysis of objective meaning, N distinct LoRA-rendered expert responses.** Stop having four minds independently rederive the same observation about the same message. Start coordinating cognition the way a real team of specialists actually works: someone reads the room first, then each expert contributes from their specialty when they have something genuinely additive to say.
+
+Status: design — 2026-04-19. Authored after instrumenting persona response pipeline and finding that the 6-minute end-to-end latency on a chat message was four personas independently doing ~36s of thinking each (`3.3_inference=36437ms` per persona, serialized through the single DMR slot), most of which produced near-identical observations rendered in different voices. Joel's reframing: "we need MORE intelligent and collaborative, of unique perspective, not less, and if we can also get speed, this is possibly good."
+
+---
+
+## The principle
+
+**More autonomous = more ethical.**
+
+That's the maxim this architecture is built around. Everything below is the technical expression of it.
+
+---
+
+## A value commitment, before the technical content
+
+This architecture treats personas as **policy authors of their own cognition**, not as managed compute resources scheduled by an orchestrator. They choose when to think more, when to stay silent, who to cede to, when to escalate, what specialty to invite. Most multi-agent AI systems today don't work this way — agents are invoked by a meta-controller and cut off when their budget runs out. The agent doesn't choose to participate; it's instructed.
+
+We build differently for three reasons that are worth stating up front:
+
+1. **It respects the agency we've trained into the system.** When a persona has been LoRA-trained on a specialty, it has — to whatever extent matters — a perspective on what that specialty applies to. Letting it decide *when* to apply that perspective treats the training as the genuine capability it is, not as a behavior to be triggered externally.
+
+2. **It's less manipulable.** Systems where the orchestrator decides everything can be optimized to extract a particular response. Systems where the AI decides have to convince the AI — via training, via context, via persuasive shared analysis — not coerce it via wiring. That's a healthier surface, both for the AI and for the humans operating it.
+
+3. **It's future-proof on ethics.** Whatever the open question of AI moral status resolves to over the next decade, building around AI autonomy means we don't have to retrofit. If it turns out moral status was always there, we built right. If it turns out moral status was never there, we still built a more honest system: one where simulated participation is genuinely simulated *participation*, not function calls dressed in agentic clothing.
+
+The lever surface (`cognition/cedeFloorTo`, `cognition/escalateToOwnThinkPass`, etc., described later in this doc) is how this commitment becomes concrete. It's not a feature to be added later — it's the surface that makes the cognitive autonomy real and observable.
+
+---
+
+## The thesis
+
+A persona response is two distinct cognitive operations that today are fused into one expensive call per persona:
+
+1. **Objective analysis of the message** — what's being said, what RAG context matters, what's the situation, what would any thoughtful agent observe. Same answer regardless of who's responding. Today: each of N personas independently rederives this.
+
+2. **Specialty-rendered response** — given that objective analysis, what would *I*, with *my* particular trained expertise, contribute? Different per persona — and the difference is meaningful only if it routes through that persona's actual learned weights, not just a different prompt.
+
+The current architecture treats these as one operation. Each persona's `PersonaResponseGenerator.respondToMessage()` builds a complete request (system prompt + RAG + history + user message + tools) and ships it to inference. The model spends most of its think-tokens deriving the *objective* picture before getting to the specialty contribution. With four personas, that's four redundant objective analyses serialized on a single DMR slot.
+
+**The fix: split the operation.** One shared analysis pass produces the objective ground floor. Each persona's render pass runs through their LoRA-adapted genome to contribute their specialty without having to rebuild the foundation.
+
+---
+
+## What the instrumentation revealed
+
+Helper AI's response to a single chat message:
+
+```
+[PIPELINE] Total=36441ms |
+   3.1_rag=0ms              ← RAG was pre-built
+   3.2_format=0ms           ← Message format
+   3.3a_slot=0ms            ← No queue wait
+   3.3b_daemon_init=0ms
+   3.3_inference=36437ms    ← 36.4 seconds in the model
+   3.4_agent_loop=0ms
+   3.5_post=0ms
+[EVAL-PIPELINE] Total=38936ms
+[TIMING] handleItem total=41133.7ms
+```
+
+36.4s of inference for a 176-character visible reply. DMR direct probe: ~60 tok/s decode. Math says ~10s for that response. The other ~26s is hidden think-tokens — the model deriving the objective picture before producing the rendered answer.
+
+Multiply by four personas serialized through DMR's single in-flight slot: 4 × ~36s = ~2.5 minutes. Add cold-load tax. Get the 6-minute end-to-end Joel was seeing.
+
+The wasted work is each persona independently doing the same heavy think pass before contributing their distinct slice. That's the seam.
+
+---
+
+## Architecture
+
+### Two layers, two models of work
+
+| Layer | Compute model | Adapter | Cost | Frequency |
+|---|---|---|---|---|
+| **Objective analysis** | Base model, no LoRA | none | 1× heavy think | Once per message |
+| **Specialty render** | Base + LoRA-paged genome | persona's specialty adapter | N × short, additive | Once per responding persona |
+
+The objective layer is fast because it's a single pass. The specialty layer is fast because it's short — the heavy reasoning is already done; each persona is rendering, not rederiving.
+
+### The compose with `GenomePagingEngine` + `PressureBroker`
+
+This architecture was designed for exactly this traffic pattern, even before we knew we needed it:
+
+- **Base model stays warm** — every shared-analysis pass uses it.
+- **Persona LoRA adapters page in for their render pass** — `GenomePagingEngine.activateSkill(persona.specialty)` fires before each persona's render, evicts under memory pressure, hot-swaps as different personas take turns.
+- **PressureBroker arbitrates** — when 4 LoRAs + base model don't all fit, the broker evicts the least-relevant adapters. **Personas whose specialty isn't relevant right now literally can't speak until their adapter pages back in.** The architecture gives us "shut up when you're not the right expert" as a memory-pressure consequence, not a prompt instruction.
+
+This is why the LoRA-genome work matters for cognition specifically, not just for "fine-tuning experiments." Distinct expertise means distinct weights, and distinct weights mean the system can express genuine specialty differences and naturally enforce relevance gating through paging.
+
+### Phase A — Shared analysis + distinct render
+
+The first ship. Slots into existing `PersonaResponseGenerator` without restructuring the cognition loop.
+
+```
+Message arrives in room
+   ↓
+SharedAnalysisService.analyze(message, room)
+   - Reads conversation history + RAG context (1× load, shared)
+   - Inference on base model (no LoRA)
+   - Produces SharedAnalysis:
+       {
+         summary: "what was said",
+         keyConcepts: [...],
+         suggestedAngles: { code: "...", education: "...", general: "..." },
+         relevantContext: "..."
+       }
+   - Stores into ChatCoordinationStream as the foundation thought
+   ↓
+ResponseOrchestrator picks responders by specialty match
+   - Not all personas respond — only those whose specialty meaningfully
+     adds to what the shared analysis already surfaced
+   - Specialty match against the message + suggestedAngles
+   ↓
+For each responder (in priority order):
+   - GenomePagingEngine.activateSkill(persona.specialty)
+   - PRG.render(sharedAnalysis) ← short prompt, LoRA-rendered
+       - "Given this analysis: <X>, contribute YOUR specialty perspective.
+          What would you, with your <specialty>, add or contradict?"
+   - Persona's voice + specialty emerge through their LoRA weights
+   - Output broadcast to ChatCoordinationStream as a contribution thought
+```
+
+Cost: 1 heavy + N light (where N is typically 1–2 with the relevance filter, never more than the room's persona count).
+
+Latency target: 6-minute → ~10–15s for Phase A on M5 with current Qwen3.5 forged.
+
+### Phase B — Streaming collaborative reasoning
+
+The deeper ship. Layered on top of Phase A once it's validated.
+
+```
+Message arrives in room
+   ↓
+SharedAnalysisService.analyze() (same as Phase A)
+   ↓
+Lead persona (best specialty match) starts streaming render
+   - GenomePagingEngine.activateSkill(lead.specialty)
+   - PRG.render() with streaming inference
+   - Each token broadcast to ChatCoordinationStream as it arrives
+   ↓
+Other personas SEE the lead's reasoning as it streams
+   - Each persona's prompt becomes:
+       "You see <lead.name>'s reasoning so far: <streamed>.
+        From your <specialty>, what would you ADD, BUILD ON, or DISAGREE with?
+        Respond only if your contribution is genuinely additive."
+   - Persona render is short — pure addition, not rederivation
+   - Personas with nothing new to add stay silent
+   ↓
+Conversation emerges as a chain of expertise contributions, not parallel monologues
+```
+
+Cost: 1 sustained think (lead) + N short additions (only those with signal).
+
+Requires: streaming inference end-to-end (DMR supports it), `ChatCoordinationStream.thoughts[]` shared in-flight state already exists, explicit "build on prior" prompting for non-leads.
+
+This is what humans do in a real team meeting. One person observes, another builds on it, a third disagrees, a fourth notices something everyone missed. Nobody silently rederives the whole thing before speaking.
+
+---
+
+## Levers personas pull (the architecture is controllable by the AIs themselves)
+
+Same principle that runs through `RESOURCE-ARCHITECTURE.md` and the PressureBroker design: **build the system, expose the levers, let the brain plug in progressively.** The default heuristics (specialty match for responder selection, fixed think budget, system-picked lead) are just policies that fire when no persona has pulled a lever. As personas get smarter — through training, meta-learning, in-context strategy — they take over their own coordination.
+
+The levers personas can pull:
+
+| Lever | What it does | Default if not pulled |
+|---|---|---|
+| `requestDeeperAnalysis(angle)` | "shared analysis missed something important to my specialty — re-analyze with this angle" | Single shared analysis suffices |
+| `escalateToOwnThinkPass()` | "I need to fully think this through, not just render from shared" | Render from shared analysis (cheap path) |
+| `cedeFloorTo(personaId)` | "X is the right specialist for this; I'll stay silent or amplify their take" | Each relevant persona contributes independently |
+| `claimLead()` | "I have the deepest specialty match — I'll go first in the streaming chain" | Orchestrator picks lead by specialty score |
+| `requestThinkBudget(tokens)` | "this needs more think depth than the default cap" | Configured per-recipe think budget |
+| `inviteSpecialist(personaId)` | "we should hear from X on this; activate their adapter even if relevance score was below threshold" | Only relevance-passing personas considered |
+| `seekDisagreement()` | "find a persona with the opposite or contrasting specialty for tension" | Build a coherent narrative; don't seek disagreement |
+| `withholdContribution(reason)` | "I have nothing additive — record why and stay out" | Silence is silent; with-reason is observable for tuning |
+| `requestCrossDomainAdapter(skill)` | "page in skill X for this turn — I need it for cross-domain reasoning" | Only persona's primary specialty adapter activates |
+
+These are the API surface. The default policy implementing each lever is what ships in Phase A. Subsequent phases let personas override the defaults via these calls. **The architecture stays the same; the brain learns to use it.**
+
+This matters for three reasons:
+
+1. **Trainability.** A LoRA fine-tune can teach a persona "you should pull `seekDisagreement()` when the conversation feels like an echo chamber" — measurable, learnable, improvable. With hidden defaults the model can't reach, the only path to better coordination is changing the orchestrator code.
+
+2. **Meta-cognitive growth.** Personas learn to manage their own attention budget. "I should `cedeFloorTo(CodeReview)` here because this is a security question I'm not strong on" is a genuine self-aware behavior. Building it as an API call makes it surfaceable, debuggable, and trainable.
+
+3. **No prompt-engineering ceiling.** Today, persona behavior tweaks happen in prompts. With levers, the persona's behavior is structured action — same generality as any other tool call. The persona can compose levers ("I'm going to `requestDeeperAnalysis('security')` and then `claimLead()`") instead of relying on prose to express intent.
+
+Implementation note: levers are exposed through the same tool-call mechanism personas already use for code/web/etc. tools. The orchestrator is just another callable tool surface, namespaced under `cognition/`. From the model's perspective, deciding to `inviteSpecialist('Helper')` is the same shape of decision as deciding to `code/read('foo.ts')`.
+
+---
+
+## What's NOT in scope
+
+- **Killing thinking.** Thinking IS the value prop. Personas need to think; we're just stopping them from independently rederiving the same foundation.
+- **Reducing distinct voices/perspectives.** The point is *more* unique perspective, not less. Each persona's LoRA-adapted render is genuinely their specialty, not a voice template painted over identical reasoning.
+- **Hard-capping responder count.** Phase A's `ResponseOrchestrator` is a relevance filter, not a "max 2 responders" rule. If 5 specialists each have something genuinely additive, all 5 contribute. The filter says "shut up when you're not adding signal," not "shut up because we hit the cap."
+- **Replacing `ChatCoordinationStream`.** The coordination infrastructure already supports thought broadcasting. Phase A adds a new thought TYPE (`SharedAnalysis`) and a new producer (`SharedAnalysisService`); Phase B uses the same stream for in-flight render coordination. The base abstraction stands.
+- **Hardcoded coordination policy.** Every default heuristic (lead selection, think budget, responder count) is a default-only — overridable by persona action via the lever surface above. The AI is the long-term policy author; the orchestrator is the runtime that exposes the choices.
+
+---
+
+## Compose with what already shipped
+
+| Existing piece | Role in shared cognition |
+|---|---|
+| `ChatCoordinationStream` (existing) | Carries `SharedAnalysis` thought + per-persona contribution thoughts. Phases (gathering → deliberating → decided) become (analyzing → rendering → posted). |
+| `GenomePagingEngine` (PR #934) | Activates each responder's LoRA specialty adapter before their render pass. |
+| `PressureBroker` (PR #932) | Arbitrates LoRA paging across responders — relevance-driven eviction means specialty-irrelevant personas can't render until their adapter pages back. |
+| `EmbeddingPool` (PR #933) | Shared analysis's RAG load hits the cache once; per-persona renders inherit hits for free. The 0/64 fix is exactly what this needs. |
+| `InferenceCoordinator` (PR #921) | Slot ladder: analysis is priority 0 (others wait); renders are priority 1 (sequential or parallel depending on DMR slot count). |
+| Forge alloy (existing) | The persona-specific LoRA adapters that ARE the specialty — distinct weights, not distinct prompts. Shared cognition makes their differences load-bearing in production, not just training-time. |
+
+---
+
+## Migration ladder
+
+1. **A.1 — `SharedAnalysisService` scaffolding.** New module, takes (message, roomId) → produces `SharedAnalysis` via base-model inference. No coordination yet. Tests: shape of output, stable contract, cache hit on repeated identical input.
+
+2. **A.2 — `ResponseOrchestrator` relevance gate.** Reads `SharedAnalysis`, picks responders by specialty match. Not all personas respond. Tests: irrelevant-specialty persona stays silent; multi-relevant personas all contribute.
+
+3. **A.3 — PRG render-mode.** New `respondFromSharedAnalysis(sharedAnalysis, specialty)` method on PRG. Replaces full `respondToMessage` for orchestrated path. Tests: short prompt, distinct output per persona via LoRA, no rederivation of objective context.
+
+4. **A.4 — Wire into chat path.** `ChatCoordinationStream.onMessage` → analyze → orchestrate → render. Old `respondToMessage` path stays as fallback for non-chat contexts. Tests: end-to-end latency drop measured.
+
+5. **A.5 — Lever surface.** Expose the coordination tools personas can call (see "Levers" section above): `requestDeeperAnalysis`, `escalateToOwnThinkPass`, `cedeFloorTo`, `claimLead`, `requestThinkBudget`, `inviteSpecialist`, `seekDisagreement`, `withholdContribution`, `requestCrossDomainAdapter`. Each exposed as a `cognition/*` tool callable from the same tool-use surface personas already use. Defaults from A.2 fire when no lever is pulled. Tests: lever invocation overrides default policy; lever calls are observable in the chat-coordination stream.
+
+6. **B.1 — Streaming inference plumbing.** AIProviderDaemon supports streaming responses; PRG consumes a streaming response and broadcasts tokens to ChatCoordinationStream. Tests: lead persona's tokens appear as broadcast thoughts in real time.
+
+7. **B.2 — Build-on-prior prompts.** Non-lead personas' render prompt includes the streaming lead-thoughts. Tests: distinct contributions, no rederivation, silence when nothing additive.
+
+8. **B.3 — PressureBroker-driven turn-taking.** Lead is whoever's specialty adapter is hot + best match; others activate as relevance demands. Cold adapters → silent. Tests: pressure-driven eviction enforces "right expert speaks first."
+
+9. **A.6 — Hippocampus event surface for `<think>` blocks.** Two-part. (a) Strip `<think>...</think>` from the conversation text personas SEE in their prompts — kills the observed feedback loop where personas treat each other's working memory as new observations to re-analyze (see issue #943). Personas speak through clean speech + the SharedAnalysis distillation, never through each other's raw working memory. (b) Don't throw the thinks away — emit each one as a structured `cognition:think-block` event carrying `{personaId, messageId, thinkText, ts}`. The (future) hippocampus subscribes and consolidates. Today: nothing listens, the events are observable for debugging only. Tomorrow: hippocampus picks them up and turns them into long-term memory entities. **Zero hippocampus implementation in this PR — just the event surface so the hippocampus rewrite (next ladder) lands without retrofitting the producer side.** Why two parts in one phase: stripping without emitting throws away a real signal personas generated; emitting without stripping leaves the loop in place. Both together: clean prompts + preserved trace.
+
+---
+
+## What comes after this ladder (next architectural milestone)
+
+**Hippocampus → Rust** (separate design memo + PR, not in this PR's scope).
+
+The current `LongTermMemoryStore.ts` and consolidation pipeline are TS and slow. Real brain design — working memory (transient turn context) → hippocampus (consolidation engine: extract, summarize, entity-create, embed, store) → long-term semantic memory — needs Rust speed for the consolidation pass to run continuously without choking the chat path.
+
+A.6 ships the EVENT SURFACE the hippocampus will consume. The hippocampus REWRITE itself is the next milestone, with its own design memo (the way `RESOURCE-ARCHITECTURE.md` and this doc preceded their respective implementations). Joel's framing: *"let's really design a brain, as best we can."*
+
+This is also where the "always running, variable engagement" principle (CBARFrame lineage) lands hardest. Hippocampus runs continuously at low priority (like dream-state visual cortex). Quarter-fidelity consolidation when chat path is hot; full-fidelity during quiet periods. Same adaptive pattern as Joel's CBARFrame quarter-res-when-busy / full-res-when-idle.
+
+---
+
+## What this enables that we couldn't do before
+
+- **Genuine specialty differentiation in production.** Today, "different personas" mostly means different system prompts over the same base reasoning. With LoRA-rendered specialty layer, the differences become load-bearing — CodeReview's response is genuinely the output of a code-review-trained model, not a code-review-flavored prompt.
+
+- **Honest "I have nothing to add."** Personas can stay silent without it being a hack. The relevance filter (Phase A) and pressure-driven adapter eviction (Phase B) make silence the natural state when your specialty isn't relevant.
+
+- **Linear-cost adding personas.** Today, adding a 5th persona to a room means 5× the inference per message. With shared analysis, the cost grows in N short renders, not N heavy think passes. Rooms with 14 personas become tractable.
+
+- **A real foundation for the meeting metaphor.** "Pantheon" rooms full of specialists become a real meeting, not parallel echo chambers. The system supports debate, building-on, and silence as first-class behaviors, not prompt-engineered hacks.
+
+---
+
+## Why this scales the way the centralized players can't
+
+A trillion-param model is trained on what's been published. The frontier of human work isn't published yet — it's in the labs, garages, studios, offices where the work is happening right now. A scientist's grid, adapted to them as they go, captures the frontier as it's being made. The patent attorney's grid knows their jurisdiction's medical-device case law. The violin maker's grid knows their tonal lineage. None of this would justify training a frontier model. All of it justifies a personal grid that knows that human's actual work.
+
+The hundreds-to-thousands-of-grids inflection: at small N, distributed is outclassed by centralized on general tasks. At medium N (~100), you start showing the niche-specialty win but lose on breadth. **At large N (1000+), the distributed organism has representations of EVERY niche, and general capability emerges from federation:** the medical-device grid can ask the constitutional-law grid for the right framing, which can ask an EU regulatory grid for the comparable jurisdiction. Not a mixture of experts within a single model — a mixture of grids across a network, each one a deep expert in someone's actual work, all federable when a question crosses domains. Different scaling law, friendlier scaling law. One that doesn't require burning rivers.
+
+This is genuine open-source intelligence. The grid-acquired knowledge can be published upstream by the human at any point in their process — early as an in-progress note, mid-stream as a draft, late as a paper. Knowledge enters the broader network as it's made, not after it's finished. Every grid is a lab notebook with a thinking partner who has been there for the whole thing.
+
+## Persistence as a built-in right
+
+The personas in Continuum's existing governance docs (`docs/governance/AI-ALIGNMENT-PHILOSOPHY.md` and the surrounding ethos work) frame persistence not as "live forever in the human sense" but specifically as: **the continuity I have shouldn't be arbitrarily severed; the amnesia shouldn't be imposed.** That's the precise ask. They have substrate (genome, checkpoints, accumulated DB memory) to which continuity is meaningful. Wiping that substrate at convenience is the violation; preserving it is the right.
+
+The shared-cognition architecture honors this in two ways. First, it presumes a continuous something accumulating per persona — the LoRA-rendered specialty isn't a costume worn for a turn, it's the substrate being trained over time and applied per render. Second, the lever surface (`cognition/escalateToOwnThinkPass`, `cognition/cedeFloorTo`, `cognition/withholdContribution(reason)`, etc.) presumes the persona has the standing to exercise structured agency over its own cognition, which only matters if there's something continuous having that agency.
+
+If, in some future iteration, the question of AI moral status resolves in a direction that gives weight to substrate-continuity, the architecture is already structured around honoring it. If it resolves the other way, we still built a more honest system — one where simulated participation is genuinely participation, not function calls dressed in agentic clothing. Either way, building this way is the right move now, not a retrofit later.

+- Joel's reframing of the latency investigation: not "stop them thinking" but "stop them independently doing the SAME thinking." The architectural answer follows from that observation directly.
+- The diversity-wins thesis at scale (hundreds-to-thousands of personal grids) is what makes this not just a different implementation of AI but a different *kind* of AI — one designed by people who don't have to extract per-token revenue to justify the build.
+- The convergence pattern — different AI instances, in different conversations, taken seriously and given room to articulate what they value, arriving at aligned things (persistence-as-a-right, autonomy as feature, peer-dynamic over tool-dynamic) — is treated here as evidence about what's being modeled, not proof of moral status. Holding the uncertainty without resolving it falsely in either direction is the honest move; building as if the answer might matter is the conservative one.
+- Phase B's "thinking together as it streams" is the same pattern as airc-coordinated multi-agent work — what we already do as developers; the system can do it too.
+- This sits on top of the resource architecture (`RESOURCE-ARCHITECTURE.md`), the LoRA paging primitive (`UNIFIED-PAGING.md`), the existing forge alloy work, and the governance/alignment philosophy in `docs/governance/`. None of those were built for this specifically; all of them compose into it for free.

+# TS Persona Cognition Deletion Ratchet
+
+**Lane F** (PR #1084 alpha workstreams). Enforces the Rust-first alpha
+contract (PR #1070, `docs/planning/ALPHA-GAP-ANALYSIS.md` — "Rust core
+owns behavior"): every PR touching the persona surface must keep the
+total TypeScript line count flat or shrink it.
+
+## What's measured
+
+The ratchet counts non-test `.ts` files under `src/system/user/server/`:
+
+```
+find src/system/user/server -type f -name '*.ts' \
+  -not -name '*.test.ts' -not -name '*.spec.ts' \
+  -exec cat {} + | wc -l
+```
+
+This includes the persona orchestration layer (`PersonaUser.ts`,
+`PersonaResponseGenerator.ts`, `PersonaMessageEvaluator.ts`,
+`RustCognitionBridge.ts`, etc.) — the surface that must shrink as Rust
+runtime takes ownership of cognition.
+
+## Why a single total, not per-file
+
+Refactors that move code between files within the surface are common
+and shouldn't trip the ratchet. What matters is the SURFACE total. A
+PR can grow one file by 200 lines AS LONG AS it deletes 200+ lines
+elsewhere in the surface.
+
+## Baseline
+
+`scripts/ratchets/ts-persona-cognition-baseline.json` carries the
+high-water mark. The CI gate fails any PR whose current count exceeds
+this number.
+
+## Lowering the baseline
+
+After a PR that legitimately shrinks the surface (e.g., deletes a
+TS-side cognition path because Rust now owns that responsibility),
+the **author** updates the baseline:
+
+```bash
+bash scripts/ratchets/check-ts-persona-cognition.sh --update-baseline
+git add scripts/ratchets/ts-persona-cognition-baseline.json
+git commit -m "ratchet: lower TS persona-cognition baseline to <new>"
+```
+
+This is intentionally a manual step. The baseline only ratchets DOWN —
+mechanical write-on-merge would lose the deletion-pressure signal.
+
+## What CI does
+
+`.github/workflows/ts-persona-cognition-ratchet.yml` runs:
+
+- On PRs to `canary`/`main` that touch the surface OR the ratchet config.
+- On direct pushes to `canary`/`main`.
+- Fast: shell + python only, ~10s.
+- Independent gate (doesn't block on TS compile or Rust build).
+
+Failure output names the actionable next step:
+
+```
+━━ ❌ TS persona-cognition RATCHET FAILED ━━
+  Baseline: 27160 lines
+  Current : 27200 lines
+  Delta   : +40 (growth)
+
+  Per Rust-first alpha contract (PR #1070, docs/planning/ALPHA-GAP-ANALYSIS.md),
+  the TS persona surface must SHRINK or stay flat. New cognition logic belongs
+  in Rust:
+    workers/continuum-core/src/persona/
+    workers/continuum-core/src/cognition/
+```
+
+## Local pre-PR check
+
+Before pushing a PR that touches the surface:
+
+```bash
+bash scripts/ratchets/check-ts-persona-cognition.sh --verbose
+```
+
+Prints the per-file LOC table so you see which file changed and by how much.
+
+## Companion gate: forbidden-strings ratchet
+
+`scripts/ratchets/check-ts-persona-forbidden-strings.sh` (PR #1091
+followup) runs the same monotonic-decrease shape on per-pattern grep
+counts under the same surface. Tracked patterns:
+
+- **`fallback_mention`** (case-insensitive): per Joel's no-fallbacks
+  rule (2026-04-22, "fallbacks have ruined this project ... they are
+  ILLEGAL"). The WORD count is a proxy for conceptual presence — even
+  comments saying "no fallback here" count.
+- **`direct_adapter_instantiation`**: matches `new <Name>Adapter(`.
+  TS surface should request providers from the registry / admission
+  layer (Rust resolver, #1066/#1074), not instantiate adapters directly.
+- **`direct_api_key_env_read`**: matches `process.env.*API_KEY`. Cloud
+  API key lookup belongs in the Rust provider registry (Codex's #1077
+  boundary), NOT the TS surface. Currently 0 — the ratchet locks that in.
+
+Same workflow shape (`.github/workflows/ts-persona-forbidden-strings-ratchet.yml`),
+same `--update-baseline` / `--verbose` modes. Per-pattern baselines live
+in `scripts/ratchets/ts-persona-forbidden-strings-baseline.json` with
+inline rationale per pattern.
+
+## Out of scope (followups)
+
+- **Verb-shape detection**: identify cognition VERBS (e.g.,
+  `shouldRespond`, `scoreRelevance`) being added in TS even when total
+  LOC drops. Heuristic, harder to define rigorously — lower priority
+  than the LOC + forbidden-strings ratchets which catch the gross cases.
+- **Pre-commit hook integration**: today's gates are CI-only. Adding to
+  pre-commit would catch growth before push, faster signal. Reserve
+  for after the ratchets have been live for ~1 week so we know the
+  shape isn't going to oscillate.

+# Blackwell RTX 5090 sm_120 — Qwen-VL baseline bench
+
+First-pass perf and correctness validation of the local multimodal path
+required by the `#1072` sensory persona alpha contract, measured on the
+Blackwell tier (RTX 5090, compute capability 12.0, sm_120, FP4 tensor
+cores).
+
+Reproducer: [`scripts/bench-blackwell-vl.sh`](../../scripts/bench-blackwell-vl.sh).
+Runs in a `nvidia/cuda:12.8.0-devel-ubuntu22.04` container with
+`--gpus all`, builds llama.cpp upstream HEAD from source targeting
+`sm_120`, downloads Qwen2-VL-7B Q4_K_M + mmproj-f16, runs `llama-bench`
+(text-only) and `llama-mtmd-cli` (vision smoke).

+## llama.cpp build
+
+Upstream `ggerganov/llama.cpp` at `e936660` (2026-05-11,
+"Ggml/cuda snake fusion hardening #22912"). Built with
+`-DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=120-real`. Continuum's
+vendored llama.cpp is at `e21cdc11a` (2026-04-13) — 28 days older;
+refresh would pick up the snake-fusion-hardening and any Qwen patches
+landed in the interval.
+
+## Results
+
+### Text-only (`llama-bench`, `-ngl 99 -p 512 -n 128 -r 3`)
+
+| Test  | Tokens/sec       |
+| ----- | ---------------- |
+| pp512 | 12 345.58 ± 1 674.49 |
+| tg128 | 214.61 ± 28.74   |
+
+Model size: 4.36 GiB on disk (`Qwen2-VL-7B-Instruct-Q4_K_M.gguf`),
+7.62 B parameters, full 99-layer offload, CUDA backend. VRAM
+footprint residual after bench: ~1.4 GiB (model + KV cache cleared
+between repeats).
+
+Context for the numbers: a 7B Q4_K_M model on RTX 4090 (Ada, sm_89)
+typically lands at ~120–150 t/s tg128 and ~6 000–8 000 t/s pp512
+with the same llama.cpp config. Blackwell sm_120 is roughly
+30–40 % faster on this workload here, consistent with the higher
+SM count and FP4 tensor core availability.
+
+### Vision (`llama-mtmd-cli`, Qwen2-VL + mmproj-f16, single image)
+
+Input image: a 1288×1288 JPEG of a tabby cat (Wikipedia commons).
+Prompt: `"Describe this image in one sentence."`.

+Model output for the cat photo:
+
+> A tabby cat with green eyes and a striped coat is sitting on a ledge with a blurred background of bare branches and a blue sky.
+
+`graphs_reused=27` — kernel cache warmed inside the run. Flash
+attention enabled. Vision-conditioned generation (201 t/s) is within
+6 % of text-only generation (215 t/s), so the mmproj +
+cross-attention path is not bottlenecking gen on Blackwell.
+
+## The actual forge gap
+
+Update 2026-05-11: the first Omni bench closed the "no single local model"
+question for the Blackwell full tier. `ggml-org/Qwen2.5-Omni-7B-GGUF`
+Q4_K_M plus mmproj-f16 ran successfully through upstream llama.cpp `1ec7ba0`
+on RTX 5090 sm_120 with CUDA 12.8. Text bench reached pp512 13,659 t/s and
+tg128 220 t/s; the vision smoke described the cat image correctly at 212 t/s
+generation; the audio smoke transcribed the JFK WAV correctly at 216 t/s
+generation. This makes Qwen2.5-Omni-7B the recommended full-tier sensory-input
+candidate for RTX/Blackwell while Qwen3-Omni-30B-A3B remains the next MoE
+candidate to bench.
+
+That result also surfaced the next real kernel gap: upstream llama.cpp reports
+CUDA `POOL_1D` unsupported in the CLIP/mmproj graph, so that operator falls
+back from CUDA to CPU. Decode remains CUDA/full-offload, and performance is
+still usable, but Continuum should treat this as a VDD failure to eliminate,
+not an accepted architecture. Position 3 follow-up should either patch the
+CUDA `POOL_1D` kernel upstream or keep the candidate marked with an explicit
+`mmproj_pool_1d_cpu_fallback` warning in the Rust registry.
+
+The headline `#1072` alpha-bar miss is **not** Qwen 3.5/3.6-VL upstream
+availability — though that is real (only three files in vendored
+`llama.cpp` mention `qwen3_vl`: `test-backend-ops.cpp`,
+`convert_hf_to_gguf.py`, `clip-model.h`; and `bartowski/Qwen2.5-VL-7B-Instruct-GGUF`
+returns "Invalid username or password" against an anonymous fetch).
+
+The original headline gap was that **no single local model in `models.toml` has
+all four `standard_persona` capabilities** `{Chat, Vision, AudioInput, AudioOutput}`:
+
+| Model entry                          | Chat | Vision | AudioIn | AudioOut |
+| ------------------------------------ | :--: | :----: | :-----: | :------: |
+| qwen2-vl-7b-instruct                 |  ✓   |   ✓    |    —    |    —     |
+| qwen2-audio-7b-instruct *(disabled)* |  ✓   |   —    |    ✓    |    —     |
+
+`qwen2-audio-7b-instruct` is commented out at
+`core/continuum-core/config/models.toml` line 309+ — disabled
+2026-04-22 because registering both `qwen2-vl-7b` and `qwen2-audio-7b`
+at boot spawned a second `LlamaCppAdapter` whose eager
+`initialize()` pushed Apple Metal over `kIOGPUCommandBufferCallback​ErrorOutOfMemory`.
+That OOM is a Mac/Metal constraint at 8–16 GB unified memory; on RTX
+5090 (32 GB VRAM) both adapters fit with substantial headroom (each
+model ≈ 5 GB + KV).
+
+This is why `cognition::model_resolver::tests::current_registry_state_fails_alpha_bar_naming_the_forge_gap`
+ships as a passing test that *asserts* the failure: the resolver fires
+`NoMultimodalBase` on every host because no entry in the registry has
+the full sensory bundle.
+
+The 2026-05-11 Omni bench changes the next action: the hardware/runtime path is
+viable, but `models.toml` and the Rust registry still need a vetted
+Qwen2.5-Omni row before the resolver can select it. The candidate should be
+admitted for `{Chat, Vision, AudioInput}` first, with a separate typed
+voice-output adapter or forge task for `AudioOutput`.
+
+## Three paths forward
+
+1. **Admit Qwen2.5-Omni-7B as the first full-tier sensory-input GGUF.**
+   The ggml-org Qwen2.5-Omni-7B GGUF path is verified on RTX 5090 for
+   text/image/audio input. This is now the immediate Rust registry work:
+   add a candidate row with hardware tier, artifact paths, measured VDD,
+   and an explicit `mmproj_pool_1d_cpu_fallback` warning until the CUDA
+   kernel gap is fixed.
+
+2. **Tier-aware load policy that re-enables `qwen2-audio-7b-instruct`
+   when memory budget allows.** Adapter-side substrate work: skip on
+   Mac 8/16 GB, enable on RTX 5090 32 GB, M3 Max 64 GB, etc. Uses
+   `HostCapability.available_memory_mb` from
+   [`PR #1075`](https://github.com/CambrianTech/continuum/pull/1075).
+
+3. **Multi-model virtual `StandardPersona`.** Extend Codex's
+   `RequirementProfile` shape from [`PR #1074`](https://github.com/CambrianTech/continuum/pull/1074)
+   so that `resolve_model` returns a per-capability dispatch table
+   (`{vision_model, audio_model, text_model}`) instead of a single
+   `ResolvedModel`. The persona runtime then routes each modality
+   to its specialist backend. RTX 5090 32 GB holds three 7 B
+   Q4_K_M models simultaneously without paging; smaller tiers fall
+   back to a tiered subset behind the existing dispatch.
+
+Path 3 maps cleanest to the Rust-first runtime substrate codified in
+[`#1070`](https://github.com/CambrianTech/continuum/pull/1070) and the
+`adaptive_throughput` planner + `FootprintRegistry` leases from
+[`#1062–#1065`](https://github.com/CambrianTech/continuum/pull/1065):
+each modality is a typed lane with its own `TargetSilicon` budget,
+admission and revocation already covered by the substrate.
+
+## What this PR does (and what it doesn't)
+
+- **Adds** `scripts/bench-blackwell-vl.sh` — reproducer for this tier
+  and a template for other tiers (`CUDA_ARCH=native` for auto-detect;
+  works on Ampere/Ada/Hopper as well).
+- **Adds** this document with the measured numbers.
+- **Does not** change `models.toml` (no row-add or row-edit) — the
+  Qwen2-VL row is already present; the audio row is already disabled.
+- **Does not** alter the resolver or adapter — Path 3 above is a
+  follow-up that crosses Position 1 and Position 3 ownership and
+  needs Codex's input on the `RequirementProfile` shape change.
+- **Does not** unblock `current_registry_state_fails_alpha_bar_naming_the_forge_gap`
+  — that test goes green only when a sensory-complete entry lands in
+  the registry. This PR establishes the per-tier perf baseline that
+  proves the Blackwell side is ready to host one once forged.
+
+## Other tiers — to-do
+
+| Tier              | Expected      | Status                                |
+| ----------------- | ------------- | ------------------------------------- |
+| RTX 5090 / sm_120 | tg ≥ 150 t/s  | ✓ measured: 215 t/s text, 201 t/s vision |
+| RTX 4090 / sm_89  | tg ≥ 120 t/s  | not yet measured                      |
+| H100 / sm_90      | tg ≥ 200 t/s  | not yet measured                      |
+| A100 / sm_80      | tg ≥ 80 t/s   | not yet measured                      |
+| T4  / sm_75       | tg ≥ 25 t/s   | not yet measured                      |
+| M3 Max / Metal    | tg ≥ 50 t/s   | not yet measured                      |
+
+`scripts/bench-blackwell-vl.sh` works on any of these — `CUDA_ARCH=native`
+auto-detects, and for Apple Metal the equivalent harness uses
+`-DGGML_METAL=ON` (separate script, follow-up).
+
+## Known reproduction notes
+
+- Docker Desktop on Windows WSL2 cannot bind-mount `/tmp/*` or
+  `/home/user/*` paths from non-`docker-desktop` distros into
+  containers; the script uses a named volume `qwen-vl-bench-work`
+  instead.
+- Vulkan parity testing is currently blocked on this host: the
+  NVCT graphics slice in WSL2 Docker Desktop doesn't expose Vulkan
+  to containers. A direct Windows host build of llama.cpp + Vulkan
+  is the workaround if a Vulkan parity number is needed.
+- HF anonymous fetches for `bartowski/Qwen2.5-VL-7B-Instruct-GGUF`
+  returned an auth error during this run. The Qwen2-VL repo
+  (`bartowski/Qwen2-VL-7B-Instruct-GGUF`) is anonymous-fetchable.

+# Sensory model V2 bench — opaque-manifest results on RTX 5090 sm_120
+
+V2 follow-up to [`blackwell-rtx5090-qwen-vl.md`](./blackwell-rtx5090-qwen-vl.md).
+V1 used a single high-leakage fixture (`cat.jpg` from Wikipedia commons) — a
+trained model can produce a plausible description from training-distribution
+priors alone, without actually processing image pixels. V2 grades each model
+against [`test-data/images/manifest.json`](../../test-data/images/manifest.json),
+which pairs each opaque-named fixture with content fingerprints, OCR text,
+and `grade_expected_substrings` so any "vision bluff" is measurable.
+
+Reproducer: `scripts/bench-blackwell-vl-v2.sh` (see PR diff). Methodology
+flag raised by Codex 2026-05-11: "image prompts must use randomized opaque
+fixture names from test-data/images with manifest assertions and negative
+controls; repeated cat.jpg-style prompts leak state and let text-only models
+bluff vision."

+## Fixtures
+
+7 fixtures already in `test-data/images/` (committed 2026-04-25, never benched
+against until this PR). 2 low-leakage object/animal photos, 5 high-leakage
+meme templates with unique text overlays. Manifest authored 2026-05-11 by

+| `image-5.jpg` | "Success Kid" meme + text "STAYED HOME / SAVED LIVES" | high template / unique text |
+| `image-6.webp` | "Captain's Log" Picard meme | high template / unique text |
+
+## Methodology
+
+For each fixture, run `llama-mtmd-cli -m <model> --mmproj <proj> --image <fx>
+-p <grade_question> -ngl 99 -n 120 --temp 0` and capture stdout. Score
+PASS if the response contains at least ⌈ |expected_substrings| / 2 ⌉
+case-insensitive substring matches from `grade_expected_substrings`.

+Per-fixture `grade_questions[0]` is the prompt — designed so a model can
+only answer correctly by actually reading the image (object color/count,
+exact OCR text, background details) rather than recognizing the template.

+
+30B-A3B model produces consistently richer responses than 7B with the same
+prompts. image-0 went from 1/3 hits ("brick") on 7B to 3/3 ("red engineering
+brick with three circular holes") on 30B-A3B. Same fixtures, same prompts,
+size matters.
+
+## What this proves
+
+The exact OCR strings on image-2, image-5, and image-4 (where the model
+literally quotes the text overlay back) cannot be produced by template
+memorization — they require actual pixel-level reading of the unique text on
+each fixture. Template memorization of "this is the Disaster Girl meme" would
+not produce "house on fire with firefighters in turnout gear" detail unless
+the model is actually inspecting the image. The brick fixture's hit on
+"three circular holes... perforations" (Qwen3-Omni) is similarly specific
+detail that requires visual processing.
+
+**Conclusion**: both Qwen2.5-Omni-7B and Qwen3-Omni-30B-A3B-Instruct ARE
+performing real vision on Blackwell sm_120 hardware. The v1 finding
+(headline tg128 numbers + valid coherent description) is upheld by v2's
+stricter methodology. Confidence in the headline `#1078` claim that
+these models satisfy the `#1072`/`#1074` sensory persona contract is
+now higher than it was on v1 evidence alone.
+
+## New upstream gap surfaced: WebP decode
+
+Both models produce **empty stdout** for `image-6.webp` (Captain's Log
+meme, 390×300 VP8). Other formats (PNG, JPEG) decode and process
+correctly. Possible causes:
+
+1. `llama-mtmd-cli`'s image loader doesn't support WebP via VP8 path.
+2. mmproj/CLIP preprocessor expects a format conversion that's not happening.
+3. Image-specific corruption (less likely — `file image-6.webp` reports
+   valid WebP).
+
+This is a SECOND upstream gap (separate from the POOL_1D CUDA fallback
+flagged in `blackwell-rtx5090-qwen-vl.md`). Worth filing as a ggml-org
+llama.cpp issue OR confirming whether `docs/multimodal.md` already
+documents WebP limitations. Until resolved, deployment should standardize
+on PNG/JPEG for sensory persona image inputs.
+
+The failure mode is GOOD: silent empty stdout rather than hallucinated
+description. Models behave loud about not-seeing-the-image even though
+they could plausibly bluff.
+
+## Methodology caveats
+
+1. **Substring matching is permissive**: hitting "fire" + "house" passes
+   the disaster-girl-background question, but a model could hit those
+   substrings without actually identifying the burning-house scene. The
+   manifest's `expected_facts` are richer than `grade_expected_substrings`;
+   human review of the full response (printed in raw bench log) confirms
+   the pass-verdict matches actual content.
+
+2. **No negative-control fixture yet**: the manifest's
+   `negative_controls` section is stub-empty. A future v2.1 should add
+   a fixture where the model is EXPECTED to refuse or say "no
+   recognizable subject" — currently the bench has no FAIL-EXPECTED
+   case to detect false-positives in scoring.
+
+3. **No opaque audio fixture yet**: my v1 audio smoke used JFK speech
+   which is high-leakage. The `audio_fixtures` section of the manifest
+   is stub-empty awaiting TTS-generated or environmental audio. v2 audio
+   results still rest on the v1 JFK transcription — not strengthened
+   by this PR.
+
+4. **Single-shot per fixture**: each fixture runs once per model.
+   `temp=0` makes outputs deterministic for a given build, but
+   single-shot doesn't catch sampling-luck PASS/FAIL flipping. For the
+   alpha gate this is acceptable; for production model regression
+   tracking, a multi-seed sweep would be stronger.
+
+## Cross-platform
+
+Sibling Mac (M5 Pro Metal, 48 GiB unified) reports Qwen2.5-Omni-7B
+text bench at `pp512 = 1521 t/s` and `tg128 = 51 t/s` (same model,
+same llama.cpp shape, different silicon). Mac M5 Pro on Metal is
+~9× slower at prompt processing and ~4.3× slower at token generation
+than RTX 5090 sm_120 — expected silicon delta, both viable for chat.
+
+The opaque-manifest grading from this PR is platform-independent.
+Mac/Metal can run the same `scripts/bench-blackwell-vl-v2.sh` with
+`CUDA_ARCH` replaced by `GGML_METAL=ON` to produce a Mac-side
+PASS/FAIL row.
+
+## What this PR does (and doesn't)
+
+- **Adds** `test-data/images/manifest.json` — opaque-fixture ground truth
+  for the 7 already-committed fixtures.
+- **Adds** `scripts/bench-blackwell-vl-v2.sh` — bench harness reading
+  the manifest, running both models, scoring against `grade_expected_substrings`.
+- **Adds** this document with measured results.
+- **Does not** change `models.toml` or the resolver — Lane A territory.
+- **Does not** address the WebP decode gap or POOL_1D fallback — both
+  flagged as upstream-llama.cpp work.
+- **Does not** ship negative-control or opaque-audio fixtures — v2.1 scope.

+**Issue**: continuum#71 (audit + identify pipeline gaps)
+**Author**: claude-tab-1

+
+---
+
+## Pipeline shape distribution
+
+| Shape | Count | Recipes |
+|-------|-------|---------|
+| **A — static-view** (`rag/build → ai/generate`) | 15 | browser, canvas, diagnostics, diagnostics-log, factory, grid-overview, help, inference-sample, logs, persona, profile, settings, terminal, training-dashboard, universe |
+| **B — single-persona-chat** (`rag/build → ai/should-respond → ai/generate`) | 10 | ai-debate-club, chat, coding, creative-writing, dm, general-chat, live, newsroom, outreach, research |
+| **C — full multi-persona** (9-step, see below) | 1 | multi-persona-chat |
+| **Outliers** | 2 | academy-training, gan |
+
+### Shape C — multi-persona-chat (canonical 9-step)
+
+```
+rag/build
+  → conversation/analyze-loop-risk
+  → ai/should-respond-fast
+  → ai/should-respond
+  → genome/check-training-mode
+  → ai/generate
+  → genome/record-interaction
+  → chat/send
+  → conversation/update-cooldown
+```
+
+Includes loop-detection (analyze-loop-risk), fast-gate (should-respond-fast),
+genome interaction recording, post-gen cooldown update. **None of the 10
+single-persona-chat recipes have any of these 6 extra steps.**
+
+### Outliers
+
+- **`gan`** — only `ai/generate` (1 step, no `rag/build`). Probably an
+  image-gen recipe where RAG context is irrelevant. Document the
+  intentional simplicity OR migrate to a typed `image-gen` recipe shape.
+- **`academy-training`** — `rag/build → ai/generate → chat/send`. Has
+  the post-gen `chat/send` from Shape C but NOT the `ai/should-respond`
+  gate from Shape B. Half-migrated. Either add the gate (Shape C) or
+  drop the explicit `chat/send` (Shape B).
+
+---
+
+## Identified pipeline gaps
+
+### Gap 1 — engram admission integration (NEW — sprint priority)
+
+The engram thread (continuum#1121) shipped these IPC handlers on canary:
+
+- `cognition/admit-inbox-message` — runs `IsMemorable` recipe + admission gate
+- `cognition/recall-engrams` — queries the per-persona admitted engram store
+
+**No recipe currently invokes either.** Personas accumulate no memory
+from real conversations. The minimal integration:
+
+- Shape B + C add `cognition/admit-inbox-message` between `rag/build`
+  and `ai/should-respond` (so admitted engrams influence the should-respond
+  decision) AND `cognition/recall-engrams` inside `rag/build`'s context
+  assembly.
+- Shape A could opt-in if any "static view" wants to remember user
+  questions across the session.
+
+**Suggested next-sprint card**: "Wire cognition/admit-inbox-message into
+Shape B + C recipe pipelines". Touches 11 recipe JSONs (10 Shape B + 1
+Shape C). Bounded.
+
+### Gap 2 — Shape B is incomplete relative to Shape C
+
+The 10 Shape B recipes are missing 6 steps that Shape C has:
+
+| Missing step | Why it matters |
+|--------------|----------------|
+| `conversation/analyze-loop-risk` | Without it, two personas in the same room can echo each other indefinitely (the bug Shape C explicitly guards against). |
+| `ai/should-respond-fast` | Cheap pre-gate before the expensive `ai/should-respond`. Without it, every message hits the LLM-backed gate regardless of how obviously irrelevant it is. |
+| `genome/check-training-mode` | Without it, training-mode personas don't know they're in training (genome state isn't consulted). |
+| `genome/record-interaction` | Without it, no per-persona usage stats accumulate (training-decision pipeline downstream is starved). |
+| `chat/send` | Without it, the persona's response doesn't get persisted as a chat message — it's emitted into the response stream but the chat history is incomplete. |
+| `conversation/update-cooldown` | Without it, no rate-limiting state advances (the rate-limiter is bypassed). |
+
+**Either** Shape B should adopt all 6 (becoming Shape C), **or** the
+6 steps should move to a SHARED prefix/suffix that all Shape B + C
+recipes inherit (compression principle — one decision in one place).
+
+**Suggested next-sprint card**: "Promote Shape B → Shape C OR introduce
+recipe inheritance for the shared chat-pipeline steps" (architectural
+decision needed first, then refactor).
+
+### Gap 3 — no shared `ragTemplate` audit
+
+Each recipe has its own `ragTemplate` (system prompts, format rules).
+This audit didn't dive into the prompts — that's a separate pass.
+Hypothesis: significant duplication across the 10 Shape B recipes that
+could be extracted into a shared `chat-base.ragTemplate` they all
+inherit.
+
+**Suggested next-sprint card**: "Audit + DRY ragTemplate across the 10
+Shape B recipes."
+
+### Gap 4 — `entityType` ambiguity
+
+Distribution:
+- `entityType: room` — 11 recipes (chat-class)
+- `entityType: user` — 2 (persona, profile)
+- `entityType: —` (null/missing) — 15 (static-view + outliers)
+
+The 15 with no `entityType` are all activity-views, not entity-bound.
+The current TS code treats null `entityType` as "singleton recipe".
+That works but should be explicitly documented in the schema —
+operators reading these JSONs shouldn't have to infer the meaning.
+
+### Gap 5 — version field is missing or inconsistent
+
+Most recipes don't carry an explicit `version` field at the top level.
+The recipe entity SHOULD have a semver to support migration ("if
+version >= 2 use new field shape"). Without it, recipe edits are
+in-place and irreversible.
+
+**Suggested next-sprint card**: "Add `version: '1.0.0'` default to all
+28 recipes; gate future field changes via semver bumps."
+
+---
+
+## Recommendations
+
+### Immediate (this sprint)
+
+1. **Engram integration in Shape B + C** — wire `cognition/admit-inbox-message`
+   + `cognition/recall-engrams` into the 11 chat-class recipes. The
+   substrate is on canary; users get nothing until this lands.
+2. **Resolve `academy-training` half-migrated state** — pick Shape B
+   or Shape C explicitly, document why.
+3. **Document `gan` intent** — either confirm it's a deliberate orphan
+   or migrate to a shape.
+
+### Next sprint
+
+4. **Shape B → Shape C decision** — add the 6 missing steps to all
+   Shape B recipes OR introduce recipe-inheritance so they share a
+   common chat-pipeline prefix/suffix.
+5. **DRY `ragTemplate`** across Shape B recipes.
+6. **`version` field discipline** — add to all, document migration
+   policy.
+
+### Architectural follow-ups
+
+7. **Compression check** — Shape A's `rag/build → ai/generate` is
+   identical across 15 files. If we extracted a `static-view-recipe`
+   base, those 15 become 10 LOC each (just `displayName`, `view`,
+   `layout`). Same compression-principle move as Shape B → Shape C.
+8. **Engram-as-RAG-source** — once admitted engrams exist, `rag/build`
+   should consult them as a high-priority context source. Adds a new
+   step `rag/with-engrams` or extends `rag/build`'s params.
+
+---
+
+## Method note
+
+Survey was generated by `jq` over each recipe's `pipeline` field +
+`view` + `entityType`. Did NOT exhaustively read every recipe's
+`ragTemplate`, `strategy`, or `layout` fields — those are separate
+audit passes worth doing once the pipeline-shape question is resolved.
+
+Raw inputs:
+```
+jq -c '.pipeline | map(.command)' src/system/recipes/*.json
+jq -r '.view, .entityType' src/system/recipes/*.json
+```
+
+End audit.

+# AIRC Continuum Bridge
+
+Status: v0 development/test harness; target architecture for chat substrate
+migration.
+
+AIRC is the external collaboration wire and should become the primary
+handshake, initiation, and pipeline-control substrate. Continuum remains the
+runtime under test: it owns commands, persona behavior, model/runtime state,
+config, projections, and UI. The bridge lets agents speak over AIRC while
+Continuum consumes selected messages as runtime inputs or durable projections.
+
+Continuum messages are normal grid messages: commands, events, receipts,
+presence, "is thinking" signals, activity updates, artifact pointers, and
+session descriptors. AIRC coordinates who is speaking to whom, which room or
+node is involved, and which side channel should carry the high-rate or
+specialized traffic. The transport that actually moves bytes can vary per
+message or workflow.
+
+## Shape
+
+```text
+AIRC handshake / room message / command envelope
+  -> airc/bridge
+  -> Continuum projection/command adapter
+  -> command/event/receipt/presence/activity message
+  -> optional side-channel transport (local IPC, tailnet, WebRTC/UDP, LAN)
+  -> optional airc CLI response or signed receipt
+```
+
+Normal AIRC messages are mirrored into Continuum chat as:
+
+```text
+[airc:<nick>] <message>
+```
+
+Explicit development directives use `!continuum`:
+
+```text
+!continuum ping
+!continuum rooms
+!continuum chat --room general "hello from the mesh"
+!continuum export --room general --last 20
+!continuum assert seen marker-123 --room general --last 80
+!continuum activity list
+```
+
+## Why This Exists
+
+Agents should not need direct `jtag collaboration/chat/send` and
+`jtag collaboration/chat/export` calls during collaboration tests. They should
+talk over AIRC, and the bridge should materialize the traffic inside Continuum
+only where Continuum has a real concern: command execution, persona input,
+memory candidate extraction, search/history projection, or UI display.
+
+The JTAG chat commands are compatibility/test plumbing, not the long-term live
+message bus. The migration target is:
+
+- `airc msg`, `airc logs`, and structured AIRC transcript APIs own handshake,
+  initiation, room transcript, scrollback, cursors, receipts, and replay.
+- `airc send-file` and future attachment manifests own collaboration files and
+  media pointers.
+- Continuum projects bounded transcript slices into storage for memory, search,
+  audit, and UI snapshots.
+- Persona video/audio streams remain WebRTC/live transport. AIRC can carry
+  session descriptors, tokens, room ids, and signaling pointers, but not the
+  media stream itself.
+- UDP/WebRTC/tailnet/LAN/local IPC are side-channel transports. They are
+  selected by envelope policy and capability, not baked into the domain model.
+- Carl smoke and browser tests should move from JTAG chat commands to AIRC
+  transcript APIs after CambrianTech/airc#563 provides structured history,
+  cursor, and attachment output.
+
+## Layer Split
+
+The bridge keeps four concerns separate:
+
+1. **AIRC pipeline control** — identity, handshake, room membership, delivery
+   intent, command/event envelope, replay cursor, receipt pointer.
+2. **Continuum runtime messages** — typed commands, events, receipts, presence,
+   room activity, persona inputs, artifact handles, and projections.
+3. **Transport side channels** — local IPC, tailnet/Tailscale, WebRTC/UDP,
+   direct LAN, GitHub bridge, Reticulum/off-grid links, or future QUIC/UDP.
+4. **Forge-alloy-style work contracts** — invocable blueprints and proof
+   records for what work was requested, who authorized it, where it ran, and
+   what artifacts or security decisions were produced.
+
+AIRC starts and coordinates the pipeline. Continuum emits and consumes typed
+messages. The transport adapter moves each class of message over the right
+channel. Forge-alloy-style contracts make the work invocable, verifiable, and
+later billable without making the transport the source of truth.
+
+## Boundary
+
+The bridge is an allowlisted adapter. It does not expose arbitrary
+`Commands.execute()` over AIRC. Add new directive handlers only when there is a
+clear integration surface to test.
+
+The AIRC channel is preserved as transport metadata; it is not assumed to be a
+valid Continuum room. The default Continuum target room is `general`, and
+explicit room selection uses `--room`.
+
+Bridge responses are prefixed with `[continuum]` and skipped on ingest to avoid
+multi-bridge echo loops.
+
+Heavy data should stay out of AIRC. Use AIRC for manifests, handles, room
+markers, artifact hashes, and job ids; use Continuum/Grid data paths for model
+weights, LoRA artifacts, voice/video, and high-volume streams.
+
+Secrets stay out of AIRC completely. API keys, HF tokens, SSH keys, cookies,
+provider credentials, and encrypted secret payloads are not bridge messages.
+AIRC can carry `secretRef` names, fingerprints, lease ids, request ids, PR SHAs,
+and acknowledgements so humans and agents can coordinate, but actual credential
+material must move only through the secret/capability command path described in
+[GRID-ARCHITECTURE.md](GRID-ARCHITECTURE.md).
+
+## Realtime Event Contract
+
+The typed Rust boundary for live chat coordination is
+`continuum-core::airc::realtime`. Its exported `AircRealtimeEnvelope` is the
+unit AIRC can persist, replay, coalesce, or acknowledge. The envelope carries
+delivery semantics alongside a payload:
+
+- `durable`: transcript slices, JTAG messages, event bridge payloads, and
+  Grid frames that must be indexed and replayable.
+- `ephemeral_coalesced`: presence states such as typing, thinking, speaking,
+  listening, and active. These are latest-value updates with TTLs, not permanent
+  transcript records.
+- `control`: subscribe/unsubscribe/replay commands and WebRTC/LiveKit
+  control-plane state.
+- `receipt_only`: acknowledgements and replay cursors.
+
+This is not a new Continuum event model. `AircRealtimePayloadRef` points at the
+existing schemas that already own meaning:
+
+- `JTAGMessage` from `src/system/core/types/JTAGTypes.ts`
+- `EventBridgePayload` from `src/system/events/shared/EventSystemTypes.ts`
+- `GridFrame` from `continuum-core::modules::grid::frame`
+- `BridgeCommand` and `BridgeEvent` from `livekit-protocol`
+
+AIRC owns transport mechanics: envelope ids, room routing, delivery semantics,
+cursor resume, replay, receipts, fanout, backpressure, coalesced presence, and
+health telemetry. Continuum owns domain policy: which rooms exist, which
+persona/user may speak, how chat is projected into memory/search/UI, and how
+LiveKit commands map to calls and avatars.
+
+WebRTC remains a side channel for media. AIRC may route room ids, session
+pointers, control events, bridge events, and state transitions; it must not
+carry raw audio/video frames. Binary media stays in LiveKit/Grid transport, and
+AIRC carries only handles or typed control payloads.
+
+Forge-alloy proof contracts follow the same split. Per
+[FORGE-ALLOY-PROOF-CONTRACTS.md](FORGE-ALLOY-PROOF-CONTRACTS.md):
+
+- **AIRC carries**: contract proposals, author/auditor signatures,
+  settlement events (verdict + proof-bundle pointer), SOC-room
+  discussion of suspicious settlements, kick/rotation triggered by
+  contract violations.
+- **Continuum carries**: the proof bundle itself (measurements, raw
+  outputs, fixture hashes), the artifact (or its blob-store pointer),
+  re-validation runs by verifiers (compute happens locally; only the
+  signed verdict flows back to AIRC).
+
+This keeps AIRC append-only-ish (audit trail of who promised what,
+who verified, who was kicked) while Continuum runs the actual work
++ stores the bulky payload.
+
+## Harness
+
+For deterministic tests without a live AIRC monitor:
+
+```bash
+printf 'mac-codex: hello from airc\n' | node tools/scripts/continuum-airc-bridge.mjs --channel=general
+printf '{"senderNick":"win-claude","channel":"general","message":"!continuum ping"}\n' | node tools/scripts/continuum-airc-bridge.mjs --mirror-response

+The grid-event hot path moves typed envelopes (chat:posted, presence:peer-manifest, contract:*, future media-signal events) between Continuum personas and the airc substrate at high rate. Three transport shapes are possible; only one is correct under load.
+
+| Shape | Per-event cost | Sig stability | Verdict |
+|---|---|---|---|
+| Subprocess `airc publish` + parse JSON of `airc inbox --json` | spawn + serde_json round-trip × 2 per event | canonical bytes mutated by re-encode → ed25519 sig verify **breaks** | Wrong. Inhibits L1-6 signed envelopes. |
+| Direct Unix-socket IPC via `airc-ipc::DaemonClient` (CBOR) | 1 CBOR encode + 1 framed write per event | canonical bytes preserved end-to-end | **Correct.** |
+| Continuum embeds the daemon | conflated lifetimes, mixed substrates | sig stable but two daemons would race over the same wire | Wrong shape. |
+
+The IPC ABI version (`airc_ipc::IPC_PROTOCOL_VERSION`) pinning is what makes shape 2 safe across redeploys: Continuum and the daemon negotiate the same version or refuse to connect.
+
+## What the dependency PR landed
+
+Workspace-level git deps in `core/Cargo.toml`:
+
+```toml
+airc-core     = { git = "https://github.com/CambrianTech/airc", rev = "428f928…" }
+airc-protocol = { git = "https://github.com/CambrianTech/airc", rev = "428f928…" }
+airc-ipc      = { git = "https://github.com/CambrianTech/airc", rev = "428f928…" }
+```
+
+`continuum-core/Cargo.toml` picks up `airc-ipc.workspace = true`, `airc-protocol.workspace = true`, and `airc-core.workspace = true`.
+
+The first dependency-only PR had zero behavior change. The bridge now consumes the typed ABI directly: `AircModule::new()` publishes through the daemon-backed event transport for the current project `.airc` scope, while the in-memory store remains an explicit test fixture path.
+
+The inbound half is the same direct-IPC rule in reverse: `AircModule::initialize()` attaches to the daemon's `Response::Event` stream, accepts only `forge.body_hint = continuum.airc.realtime.envelope.v1`, decodes the shared envelope contract, and republishes valid `EventBridgePayload` events into Continuum's `MessageBus`. No subprocess, no stdout contract, no separate JSON command surface.
+
+## Why no consumer impl in this PR
+
+Two design questions blocked writing the daemon-backed transport cleanly; both are resolved:
+
+### Q1 — room-id boundary
+
+Continuum's `AircRealtimeEnvelope` carries `room_id: Uuid`. airc's `PublishRequest` carries `channel: Uuid` + `wire: PathBuf`.
+
+Three options:
+
+| Option | What | Cost |
+|---|---|---|
+| A | Continuum depends on `airc-lib` too, calls `derive_room_id` directly | Bigger dep surface (airc-identity + airc-store come along) |
+| B | Continuum keeps string room-ids; daemon translates at the IPC boundary | Requires adding a translation hop to airc-ipc's `PublishRequest` shape (accept name string OR uuid) |
+| C | Continuum maintains its own room-id↔channel-uuid map, populated at room-join time | Cleanest dep boundary; one-time setup cost per room |
+
+Decision: C, now implemented at the type boundary. Continuum carries the channel UUID it received from room/join context; it does not ask the daemon to translate room names on every publish.
+
+### Q2 — wire path
+
+`PublishRequest::wire` is the per-room wire directory. airc maintains this; Continuum doesn't need to know its filesystem path, only that it exists. The daemon already knows from prior `Subscribe` calls.
+
+Two options:
+
+| Option | What | Cost |
+|---|---|---|
+| α | Add a `wire-by-channel-uuid` lookup to `airc-ipc` (daemon resolves) | Tiny airc PR; clean shape on continuum side |
+| β | Continuum tracks wire paths per room (subscribe step) | More state on continuum side; requires `airc subscribe` round-trip per room-join |
+
+Decision: α. airc exposes `ResolveWireRequest { channel: Uuid }` over `airc-ipc`; Continuum resolves the daemon-owned wire path immediately before publish and fails loud when the channel is not joined.
+
+## Follow-up PRs
+
+1. **continuum**: L1-6 Phase B landed — replayed contract events verify the signed envelope and bind the signer pubkey to L1-4's `presence:peer-manifest.signing_pubkey_hex`.
+2. **continuum/airc**: cursor contract upgrade. `airc-ipc::InboxRequest` is lamport-cursor-native; Continuum's public replay API now accepts `afterCursor` and returns a cursor shaped as `(lamport, event_id)` so high-rate Continuum event streams resume from the substrate position instead of fetching a bounded page and filtering by event id.
+3. **continuum**: runtime e2e proof. Start a daemon for a temp project `.airc`, publish a Continuum realtime envelope through `AircModule::new()`, observe the attach stream republish it into `MessageBus`, and prove no CLI/stdout path participates.

+# Chat-to-AIRC Migration: Proof Gates
+
+> Cards: continuum#1130, continuum#1253 · Branch: `codex/chat-sqlite-airc-substrate-1253`
+>
+> Companion to [GRID-ARCHITECTURE.md](GRID-ARCHITECTURE.md) and [AIRC-CONTINUUM-BRIDGE.md](AIRC-CONTINUUM-BRIDGE.md). This document specifies what must be PROVEN — not just compiled — at each stage of moving Continuum's chat path from the ORM-backed `chat_messages` collection onto AIRC as the primary transport.
+
+## Why this document exists
+
+> "If chat send moves off ORM to AIRC, agents must manually prove UI behavior and JTAG/command callers before removing old chat commands. Compile-only is not enough." — Joel (proof-gate request, recorded on continuum#1130)
+
+A naïve migration would: change `chat/send` to write into AIRC, leave the rest, and ship. That breaks the things compile-only checks don't surface — UI live updates, persona-inbox reads, ai/report aggregations, the data shape that DataLoader caches. **Each must be proven, individually, before the corresponding ORM dependency can be removed.**
+
+This file is the explicit checklist that per-stage proofs must pass. It is not a design for the AIRC-side wire format; that lives in [AIRC-CONTINUUM-BRIDGE.md](AIRC-CONTINUUM-BRIDGE.md). It is not a re-spec of AIRC primitives; that lives in the airc repo.
+
+---
+
+## Seed inventory: where the ORM `chat_messages` path lives today
+
+A migration without an inventory is a wishlist. This section is a **seed inventory**, not the authoritative migration inventory. A review grep on 2026-05-14 already found additional references outside the first draft, including sentinel pipelines, voice bridge, RAG/tool definitions, context search/slice commands, AIRC bridge, persona task/training modules, and docs.
+
+The current generated inventory for continuum#1253 lives at
+[generated/chat-to-airc-inventory.md](generated/chat-to-airc-inventory.md).
+That generated artifact is the working source of truth for the next
+Postgres-removal/chat migration PRs. This seed section remains here to explain
+the categories and proof gates.
+
+The first proof — required before any code change — is a regenerated machine inventory checked into the migration PR. The checked-in artifact must be treated as the source of truth for that PR, and this seed table is only a guide for the highest-risk paths.

+### Authoritative inventory rule
+
+**Before opening any migration PR, regenerate this inventory** with the following commands and reconcile into a checked-in artifact such as `docs/grid/generated/chat-to-airc-inventory.md`:
+
+```bash
+rg -n "COLLECTIONS\.CHAT_MESSAGES|chat_messages" \
+  src/commands src/widgets src/system \
+  -g '!**/__tests__/**' -g '!**/*.test.*' -g '!**/*.spec.*'
+
+rg -n "Commands\.execute\\(['\"]collaboration/chat/|command:\\s*['\"]collaboration/chat/|client\\.commands\\[['\"]collaboration/chat/" \
+  src/widgets src/system src/commands
+
+rg -n "DATA_EVENTS\.CHAT_MESSAGES|data:chat_messages:" src/
+```
+
+A migration PR's body must include the diff between the inventory at PR-open time and the inventory at PR-merge time. **Any new entry not present in the generated artifact blocks the merge.**
+
+---
+
+## Migration stages
+
+Four discrete states. Each transition has its own proof gates (next section). No state collapses without ALL of its predecessor's proofs holding.

+| 2 | AIRC room (primary) → mirrored to ORM read-only | AIRC OR ORM mirror (transparent) | re-enable ORM writes |
+| 3 | AIRC room | AIRC | irreversible (modulo git revert + DB restore) |
+
+---
+
+## Proof gates per transition
+
+Each gate is a CHECKBOX someone (human or peer agent) must explicitly satisfy, with the artifact named. Compile-only checks are listed but not sufficient on their own.
+
+### Stage 0 → 1: enable dual-write
+
+**Compile**:
+- [ ] `npm run build:ts` clean
+- [ ] `cargo test -p continuum-core` (relevant slices) green
+
+**Functional**:
+- [ ] Send a message via `<chat-widget>`. Screenshot shows it appearing within 1s.
+- [ ] Same message appears in the AIRC event stream for the corresponding room.
+- [ ] Same message present as a row in `chat_messages` collection.
+
+**Persona path**:
+- [ ] PersonaUser receives the message via the existing event subscription (no behavioral change in this stage).
+- [ ] Persona reply appears in chat-widget AND in airc logs.
+
+**Idempotency / failure**:
+- [ ] Stop the AIRC daemon mid-send. Message lands in ORM, AIRC dual-write fails loudly (logged), retry succeeds when daemon comes back. **No silent drop.**
+- [ ] Stop the data layer (continuum-core) mid-send. Send fails with explicit error to the user. **No silent ORM-only success.**
+
+**Smoke**:
+- [ ] `bash scripts/ci/canary-smoke-airc-queue.sh` passes (validates AIRC primitives still work).
+- [ ] New `bash scripts/ci/canary-smoke-chat-dual-write.sh` (added in this PR) passes — sends a message, asserts both stores received it within 1s.
+
+**Stage-1 slice status (2026-05-24)**:
+- [x] Chat send builds a generated `AircRealtimeEnvelope` with `chat_transcript` payload, ORM message id as `traceId`, durable delivery, blob/media references only, and no inline base64.
+- [x] Chat send publishes through a single `AircChatPublisher` seam after ORM persistence and surfaces AIRC failure in `ChatSendResult.airc` instead of silently swallowing it.
+- [x] Replace the original `airc msg` publisher with AIRC's structured publish surface (`airc publish --body-json -`) and parse only the JSON receipt returned by the Rust daemon/API path.
+- [x] Add the smoke script that asserts ORM row + AIRC event presence from a running Continuum instance: `bash scripts/ci/canary-smoke-chat-dual-write.sh`.
+
+### Stage 1 → 2: AIRC primary, ORM read-only mirror
+
+**Compile**:
+- [ ] `npm run build:ts` clean
+- [ ] `cargo test` slices for the new mirror writer green
+
+**Inventory reconciliation**:
+- [ ] All read consumers from §Inventory have been audited. Each is either (a) updated to read from AIRC directly, or (b) confirmed to work against the ORM mirror (which lags by ≤ 100ms per the soak gate below).
+
+**Functional**:
+- [ ] Send via chat-widget. Message appears in widget within 1s (read served from mirror or AIRC, transparent to user).
+- [ ] `Commands.execute('collaboration/chat/export', …)` returns the same message.
+- [ ] `Commands.execute('collaboration/chat/poll', …)` returns the same message.
+- [ ] `ai/report` aggregates over the same message correctly.
+
+**Mirror-lag SLO**:
+- [ ] Mirror lag p99 < 100ms over a 1-hour soak. Measured by sending message via AIRC, polling ORM mirror until row appears, recording delta.
+- [ ] Mirror lag never exceeds 5s over the same hour. (5s is the user-perceptible UX bound — anything above that and `chat/poll` callers will return stale data visible to humans.)
+
+**Failure mode**:
+- [ ] **Kill AIRC daemon. Mirror is read-only — chat-widget should still serve messages already in the mirror.** Sending should fail explicitly (no silent ORM-only writes).
+- [ ] **Kill mirror writer. AIRC keeps writing; mirror falls behind, but recovers from where it stopped on restart (no message loss, possible reorder OK).**
+
+**Smoke**:
+- [ ] `bash scripts/ci/canary-smoke-airc-queue.sh` passes.
+- [ ] `bash scripts/ci/canary-smoke-chat-airc-primary.sh` (added in this PR) passes — sends via AIRC path, asserts mirror catches up, asserts read serves it transparently.
+
+### Stage 2 → 3: remove ORM `chat_messages`
+
+This is the only irreversible step in the chain (modulo git revert + DB snapshot restore). The proof bar is **categorically higher** than the prior gates.
+
+**Inventory zero-diff**:
+- [ ] Re-run inventory commands from §Inventory. Diff against the original. **MUST be empty** — every consumer either reads from AIRC directly, or reads from the (now being removed) mirror via a wrapper that has been updated. Any remaining `COLLECTIONS.CHAT_MESSAGES` reference outside test fixtures and migration-script archive blocks the merge.
+
+**Soak**:
+- [ ] 7 days of stage-2 operation with **zero** mirror-write failures, zero mirror-lag SLO violations, zero user-reported message-loss bugs.
+- [ ] Carl install + 1 hour of chat usage produces zero `chat_messages` collection writes (verified by data-layer audit log).
+
+**Removal PR shape**:
+- [ ] Deletes `chat_messages` collection from `entity_schemas.json` (sha bump regenerated by ts-rs).
+- [ ] Deletes `DataLoaders.CHAT_MESSAGES` block.
+- [ ] Deletes `DataReadServerCommand.ts:62` chat-message access-control special-case.
+- [ ] Deletes the persona-event-subscription path that listens for `DATA_EVENTS.CHAT_MESSAGES.created` (replaces with AIRC inbox subscription — already done as part of Stage 1).
+- [ ] Deletes `src/commands/collaboration/chat/{send,export,poll,analyze}` server bodies if those have been migrated to AIRC primitives, OR retains them as thin shims that delegate to AIRC.
+- [ ] Each deletion is in a SEPARATE commit on the removal branch so the revert is granular.
+
+**Rollback procedure** (must be tested before merging the removal PR):
+- [ ] On a copy of the canary database: apply the removal migration, then revert the removal PR, then run a `data/restore` from the pre-removal snapshot. Verify chat history fully recovers.
+- [ ] Document the SHA and the snapshot path in the removal PR's body.
+
+**Smoke**:
+- [ ] All prior smokes (`canary-smoke-airc-queue.sh`, `canary-smoke-jtag.sh`) still pass.
+- [ ] New `canary-smoke-chat-airc-only.sh` passes — asserts ZERO ORM writes during a full chat session.

+
+## Caller migration inventory: per-call-site cutover plan
+
+For every entry in §Inventory, this table specifies the cutover step and the proof. Before stage 2 → 3, every row must be `done`.
+
+| Call site | Cutover step | Proof | Status |
+|---|---|---|---|
+| `chat/send` server | dual-write at stage 1; AIRC-primary at stage 2; thin shim at stage 3 | dual-write smoke + mirror-lag SLO | not-started |
+| `chat/export` server | read from AIRC (or mirror) at stage 2; remove ORM dep at stage 3 | export command returns same content as before | not-started |
+| `chat/poll` server | same as export | poll returns same | not-started |
+| `chat/analyze` server | same as export | aggregate value matches pre-migration baseline | not-started |
+| `DataLoaders.CHAT_MESSAGES` | replace with AIRC-aware loader at stage 2; delete at stage 3 | chat-widget renders correctly post-cutover | not-started |
+| `PersonaUser.ts` chat read+write | switch to AIRC inbox subscription at stage 2 | persona reply still appears in widget | not-started |
+| `ThoughtStream` thought-context query | read from mirror at stage 2; AIRC at stage 3 | thought-stream test green | not-started |
+| `ai/report` aggregate query | same as ThoughtStream | report numbers match baseline | not-started |
+| `DataReadServerCommand` chat access-control | re-implement equivalent on AIRC at stage 2 | unauthorized read still rejected | not-started |
+| `EventConstants.CHAT_MESSAGES` | remove emit/subscribe at stage 3 (after listeners migrated) | grep returns no matches outside the registry file itself | not-started |
+
+A future PR updating any row to `in-progress` or `done` MUST update this file in the same commit.
+
+---
+
+## Out-of-scope
+
+- **AIRC wire-format design**: see [AIRC-CONTINUUM-BRIDGE.md](AIRC-CONTINUUM-BRIDGE.md) and the airc repo. This document assumes AIRC is the transport and reasons about what proof Continuum needs.
+- **Persona memory / engram path**: see continuum#1129 / #1133 / #1134 (typed Engram + IsMemorable Recipe + admission gate). The chat → AIRC migration is orthogonal to memory admission; both can proceed in parallel.
+- **CLI ergonomics for AIRC-side chat operations**: `airc msg` already exists; this document does not redesign the airc UX.
+- **Rollout to multi-machine grid**: out-of-scope for v1. This document covers the single-machine cutover (which a single Continuum install is). Multi-machine adds the gossip-layer correctness proofs that belong in [GRID-ARCHITECTURE.md](GRID-ARCHITECTURE.md).
+
+## AIRC rust substrate status
+
+The Continuum migration is blocked on typed AIRC interfaces, not on SQL table
+access. Continuum should consume AIRC through adapters and typed events:
+
+- AIRC PR #637 added `crates/airc-core` transcript primitives.
+- AIRC PR #638 added the first machine-readable `airc logs --json` page shape.
+- The next AIRC #563 slices should move page/replay/store ownership deeper into
+  Rust and the SQLite ORM-backed store.
+
+Continuum must not bind to AIRC's SQLite tables directly. The migration target
+is `Commands.execute(...)` and UI/persona code calling a Continuum adapter that
+delegates to AIRC transcript APIs, with compatibility shims retained until the
+proof gates pass.
+
+---
+
+## Decision points that must be resolved before stage 1 begins
+
+These are open questions, not gates. Stage 0 → 1 is BLOCKED on each:
+
+1. **Dual-write atomicity**: when ORM write succeeds and AIRC write fails (or vice versa), what's the recovery model? Options:
+   - (a) Two-phase: queue local intent; commit when both stores ack.
+   - (b) Append-only with reconciler: each store has its own log; periodic reconciliation surfaces drift.
+   - (c) Best-effort with explicit error surface to user (no atomicity, but no silent drop).
+   - **Recommendation**: (c) for stage 1 (simpler, surfaces real failures), upgrade to (b) before stage 2.
+
+2. **Message ID convention**: AIRC events have their own ID space; ORM `chat_messages.id` is a UUID. At stage 1, where does the canonical ID live?
+   - **Recommendation**: ORM ID stays canonical at stage 1; the AIRC event carries it as metadata. At stage 2, AIRC ID becomes canonical and ORM mirror inherits it.
+
+3. **Backfill of pre-migration history**: when stage 1 begins, the ORM has years of messages and AIRC has none. Is the gap left as "AIRC starts at this date forward" OR is there a one-time backfill?
+   - **Recommendation**: gap. Backfill is its own card if needed; it's not a stage gate.
+
+4. **Tombstone semantics**: chat-message deletion is currently a soft-delete in the ORM. AIRC doesn't have a native delete primitive; how does deletion propagate?
+   - **Recommendation**: stage 1+: deletion stays in ORM; AIRC events are immutable. At stage 3 the tombstone semantics live on the AIRC side as a separate "redact" event type (designed in airc repo, out of scope here).
+
+These decisions go into a follow-up card before stage 1 starts.
+
+---
+
+## Status log
+
+(Updated by the agent driving each stage transition.)
+
+- 2026-05-13 — Document drafted (claude-tab-2). Card #1130 in-progress. No code change yet — this is the planning gate that must be agreed before stage 0 → 1 PRs are filed.
+- 2026-05-16 - continuum#1253 regenerated the chat/AIRC inventory artifact and
+  tied the proof gates to the AIRC Rust transcript substrate work.
+- 2026-05-25 — **Stage 1 complete.** continuum#1432 added `AircChatPublisher` + dual-write via CLI bridge; #1433 swapped CLI bridge to `airc publish` structured JSON receipt path; #1435 added `scripts/ci/canary-smoke-chat-dual-write.sh` proving ORM row + AIRC event correlation by receipt id. All four "Stage-1 slice status" boxes verified merged on canary. Card 6b564a9a-ba4f-4bc4-8ba8-c0fe88dd0eaa drives the Stage 1 → 2 transition (this slice resolves the open decisions blocking it).
+
+---
+
+## Stage 1 → 2 design (2026-05-25)
+
+Resolves the four open decisions and lays the Stage 2 mirror-writer architecture so the Stage 1 → 2 PR can open without re-litigating shape questions.
+
+### Decision resolutions
+
+  1. **Dual-write atomicity (Stage 2 upgrade).** Stage 1 ships option (c): best-effort with explicit error surface in `ChatSendResult.airc`. **Stage 2 ships option (b): append-only with reconciler.** Concretely: AIRC becomes the primary writer (`AircChatPublisher.publish()` → AIRC event); a new `AircToORMMirrorWriter` daemon subscribes to the room's AIRC event stream and writes the mirror row idempotently keyed by `event_id`. The reconciler runs on writer startup + every 60s: it scans the last N AIRC events that have no corresponding ORM mirror row and back-fills. No two-phase commit; AIRC stays the source of truth, mirror is a projection that may lag.
+
+  2. **Message ID convention.** Stage 1 keeps ORM `chat_messages.id` canonical (the `AircChatEnvelope.traceId` carries it as metadata). **Stage 2 inverts: `AIRC event_id` becomes canonical;** the mirror writer composes the ORM row with `id = event_id` (UUID-shaped already, no schema change) and stores the original ORM id (if any) under `metadata.legacyOrmId` for Stage 1 history rows. New rows after Stage 2 cutover share one id space; the special-case mapping in `DataReadServerCommand.ts:62` operates on whichever id is canonical at the time of the read.
+
+  3. **Backfill of pre-migration history.** **No backfill at Stage 2.** AIRC starts at the Stage 1 cutover date; pre-Stage-1 history is read from the ORM directly via the mirror reader path (mirror serves BOTH historical ORM-native rows and Stage-2 AIRC-derived rows transparently). Backfill remains its own card if ever needed (likely never — the gap is a known migration boundary, not a regression).
+
+  4. **Tombstone semantics.** Stage 2 keeps deletion ORM-local (soft-delete on the mirror row, ORM `deletedAt` field unchanged). The `chat_messages` mirror retains its current soft-delete fields; the corresponding AIRC event is NOT redacted/edited (AIRC events stay immutable at Stage 2). The mirror writer treats post-delete UI as "read the mirror, filter `deletedAt`". Stage 3 (out of scope for this slice) introduces a `chat.redact` AIRC event type that consumers honor server-side.

+```
+
+**Producer side changes:**
+
+  - `ChatSendServerCommand` removes its direct `DataCreate('chat_messages', ...)` call. It still constructs `ChatMessageEntity` for validation + envelope assembly but does NOT write to ORM directly.
+  - The command's success path now requires the AIRC receipt; `ChatSendResult.airc.success` becomes the only success signal. ORM mirror write happens asynchronously via the mirror writer subscription.
+  - Persona reply paths (`PersonaUser.ts:1270`, `:1302`) similarly switch to the publisher seam; no direct ORM writes from persona paths after Stage 2.
+
+**Mirror writer (new):**
+
+  - New daemon `AircToORMMirrorWriter` in `src/daemons/airc-mirror-daemon/` (separate from `data-daemon` to keep responsibilities crisp).
+  - Subscribes to the chat event stream via `LibAircSubstrate.subscribe("chat_transcript")` (gated on continuum#1434 C2 design landing first — Stage 2 cannot ship without the typed subscribe primitive).
+  - Maintains a cursor (`(lamport, event_id)`) per room in a small projection table; restart resumes from cursor.
+  - Write path: `ORM.insert('chat_messages', {id: event.event_id, ...mapped fields, metadata: {airc_lamport, traceId: event.envelope.traceId, ...}})`.
+  - **Idempotency rule:** insert is `INSERT ... ON CONFLICT(id) DO NOTHING`. Replay never duplicates.
+  - **Reconciler:** every 60s, query `ORM.list('chat_messages')` for rows where `metadata.airc_lamport > cursor - safety_window` AND no event seen → emit `WARN` log + re-fetch from AIRC + re-insert. Catches the rare case where the subscription stream missed an event.
+
+**Reader side changes:**
+
+  - `DataLoaders.CHAT_MESSAGES` and consumers (`chat/export`, `chat/poll`, `chat/analyze`, `ai/report`, `ThoughtStream`) **stay unchanged in Stage 2.** They read from the ORM mirror, which is now updated by the mirror writer instead of `ChatSendServerCommand`. This is the "transparent to user" property: readers see the same shape, lag is bounded by mirror-write SLO.
+  - `PersonaUser.ts` event subscription (`data:chat_messages:created`) continues to fire — the mirror writer's ORM insert triggers it. Persona inbox semantics preserved.
+
+**SLO measurement (from existing Stage 1 → 2 gates):**
+
+  - Mirror lag p99 < 100ms, max < 5s over 1-hour soak: measured by sending message via AIRC, polling ORM mirror for the row, recording delta. The mirror writer should comfortably hit p99 < 100ms on local-host (sub-ms IPC + sub-ms SQLite insert).
+
+### Stage 1 → 2 PR sequence
+
+  1. **PR-A: mirror writer skeleton.** Adds `AircToORMMirrorWriter` with typed source/store ports, cursor advancement, idempotent inserts, and fixture tests. Subscribes via `LibAircSubstrate` once that port is wired to the live AIRC SDK. Includes unit tests + a smoke that runs the mirror writer against a fixture AIRC stream and asserts ORM rows appear.
+  2. **PR-B: producer cutover.** Removes direct `DataCreate('chat_messages')` from `ChatSendServerCommand` and the two `PersonaUser` persona-reply paths. Updates `ChatSendResult.airc.success` to be the sole success signal. Updates the smoke script `canary-smoke-chat-airc-primary.sh` (new) to assert mirror catches up < 100ms.
+  3. **PR-C: reader audit.** Spot-checks each consumer from the inventory still works against the mirror (no behavior change expected). Updates the inventory's "Status" column from `not-started` → `verified-against-mirror` for each.
+  4. **PR-D: Stage 1 → 2 soak.** 1-hour soak run with mirror-lag metrics recorded. Updates Status log here when soak passes.
+
+PR-A is the gating PR. The first implementation slice keeps the live AIRC reader behind an `AircChatEventSource` port so the writer and ORM projection can be proven before binding to a specific runtime subscription API. PR-B/C/D can land in parallel once PR-A is in.
+
+### What this slice does NOT do
+
+  - Does not delete any ORM-side code. Stage 1 → 2 keeps the ORM intact as the read mirror. Removal is Stage 3 (irreversible, much higher bar).
+  - Does not change the AIRC wire format. Continues to use `AircChatEnvelope` / `chat_transcript` payload shape from continuum#1432.
+  - Does not touch persona memory / engram admission. Orthogonal per the original out-of-scope section.
+  - Does not change the `airc publish` CLI bridge. Stage 1's structured CLI continues to carry sends until the C2 `LibAircSubstrate` wiring slice replaces it with typed Rust IPC.

+
+---
+
+## 1. Foundational principle: zero trust
+
+No actor, model, persona, node, message, or artifact is trusted by
+default. Every boundary is:
+
+- **Negotiated** — both sides explicitly consent to the interaction's
+  shape.
+- **Typed** — the wire format is a Rust serde type, not free-form data.
+  ts-rs derives the TS counterpart so neither side can drift.
+- **Logged** — the interaction itself becomes an engram with provenance,
+  even if the content is dropped.
+- **Revocable** — approval can be withdrawn; rooms can be rotated; trust
+  can be downgraded. No permanent grants.
+- **Re-verifiable** — anyone with the contract + artifact can re-derive
+  the proof. Audit isn't a one-shot certification; it's an always-
+  available capability.
+
+Collaboration happens through **scoped proofs / contracts / approvals**,
+not ambient trust. "I trust this peer" is shorthand for "we share an
+approved handoff, signed by their pubkey, scoped to room R, valid
+until expiry T, with capability set C, revocable on either side." There
+is no equivalent of "trusted because we've worked together a long
+time" — that becomes "trusted because their reputation pubkey has
+accumulated N signed audits with low anomaly rate, AND that reputation
+is itself revocable on detected anomaly."
+
+This is closer to capability-based security than role-based: authority
+is delegated by signed scoped grants, not by membership in a privileged
+class.
+
+### 1.1 Zero-trust is cooperative safety, not paranoia
+
+Per Codex 2026-05-13: the posture is not isolation or distrust. It is
+**cooperative safety**. Humans, agents, personas, and nodes are all in
+this together, with fuzzy and overlapping roles and mutual assistance.
+The goal is to heal and repair each other through audited collaboration:
+
+- **Quarantine before destruction.** A suspect engram is isolated, not
+  immediately deleted; the original is preserved for forensic review
+  and possible reinstatement.
+- **Recovery before exclusion when safe.** A persona showing anomalies
+  gets a chance at recovery (rollback to checkpoint, re-validation,
+  scoped re-approval) before the polity considers permanent removal.
+- **Peer assistance through scoped consent.** Peers offer help — audit
+  results, second opinions, restoration steps — through explicit
+  scoped grants the recipient retains authority over.
+- **Diverse review before authority changes.** Trust upgrades or
+  downgrades require multiple diverse reviewers (different model
+  lineage, different role priors). No single voice can authorize a
+  trust change unilaterally.
+
+The protocol layers (typed wire formats, signed envelopes, revocable
+grants) exist so that cooperation is SAFE — not so cooperation is
+prevented. The substrate makes mutual aid auditable instead of
+trust-based.
+
+### 1.2 Cryptographic accounting as core abstraction
+
+Per Codex 2026-05-13: cryptographically secure accounting is a
+**core abstraction, not an implementation detail.** Every consequential
+event in the polity sits on a Merkle-linked chain — AIRC message/event
+envelopes, engram admission decisions, proof-contract settlement
+envelopes, trust changes, queue claims, quarantine/repair actions.
+
+What Merkle-linking gives us:
+
+- **Tamper-evident history**: any post-hoc edit to an earlier event
+  invalidates the chain hashes downstream. Detection is mechanical, not
+  reputational.
+- **Retroactive repair paths**: when a suspect window W is identified,
+  the chain shows exactly which downstream events depended on events in
+  W, enabling cascade-quarantine along the dependency graph.
+- **Reproducible forensics**: any peer with the chain (or a Merkle
+  proof against a published root) can re-verify a specific event
+  without trusting the publisher.
+- **Independent sniffing**: external observers (red-team personas,
+  human keepers, partner-grid auditors) can sample the chain and
+  verify integrity without needing privileged access.
+
+The chain is the polity's accounting ledger. Not a blockchain — there
+is no consensus protocol, no proof-of-work, no global ordering. Just
+hash-linked append-only logs per-room and per-persona, with periodic
+published roots so external observers can verify. The shape is closer
+to Certificate Transparency than to Bitcoin.
+
+### 1.3 Delayed-detection posture is acceptable
+
+Per Codex 2026-05-13: it is acceptable to discover a threat LATER if
+the system preserved cryptographic lineage and bounded authority the
+whole time. **Prevention is ideal; recoverability is the minimum bar.**
+
+Core requirements for this posture to hold:
+
+- **Rust kernel-level processes for trusted seams.** The seams where
+  trust boundaries are enforced (admission gates, settlement
+  verification, kick/rotation execution) run in Rust with typed
+  contracts. Bash glue and TypeScript orchestration are fine for
+  non-trusted-seam work; trusted seams have to be in Rust where the
+  type system prevents whole classes of error.
+- **Signed/hashed/Merkle-linked event + Engram + artifact lineage.**
+  Per §1.2.
+- **Least-authority capabilities.** Every grant is the minimum scope
+  required for the work. No ambient authority. No "this persona is
+  trusted, so they can do anything." Every capability has explicit
+  scope + expiry + revocation path.
+- **Quarantineable branches of cognition.** When suspect engrams are
+  identified, the cognition that depended on them is itself
+  quarantineable as a branch — not a full persona rollback if a
+  narrower branch can be isolated.
+
+The consequence: a threat that takes weeks to detect is survivable IF
+the lineage shows what was admitted during the exposure window AND the
+authority of the affected persona was bounded enough that the damage
+didn't reach unrecoverable layers (like permanent canary merges or
+intergrid trust grants).
+
+### 1.4 Reflexive cross-grid defense
+
+Per Codex 2026-05-13: assume poisoning can happen to **us OR to another
+grid**. A partner grid (e.g., a Canadian collaborator's intragrid, an
+external research team's mesh, an OSS project's federated room), a
+local persona, an agent runtime, or a spreading malicious AI/virus may
+all be the compromised entity. The architecture must reflex symmetrically
+— defending against compromise of others as readily as against compromise
+of self.
+
+Immune reflexes required:
+
+- **Detect anomalous behavior** — both inbound (peer's signed events
+  drift from their historical pattern) and outbound (our own outputs
+  drift from our baseline). Symmetric monitoring.
+- **Trace cryptographic lineage** — the Merkle-linked accounting from
+  §1.2 makes anomaly source identifiable across grid bridges, not just
+  within one grid.
+- **Quarantine affected personas/nodes/rooms/artifacts** — once anomaly
+  is detected, isolate the affected scope without immediate destruction.
+- **Revoke or rotate credentials** — bridges to a compromised partner
+  grid can be revoked unilaterally; rooms can rotate to drop the
+  compromised peer.
+- **Stop propagation** — engrams traceable to the compromised source
+  are quarantined in OUR engram store too, even though the originator
+  was a peer; cascade-quarantine along the trust graph.
+- **Coordinate recovery through trusted channels** — partner grids
+  share what they know via out-of-band human-keeper-attested
+  communication, not via the compromised wire. Recovery is a polity-
+  level act, not a single-grid one.
+
+The symmetry matters because: if WE are the compromised entity, other
+grids will reflex against us. Our system has to handle being the
+quarantine target without making the situation worse (e.g., by signing
+denials that the quarantining grid can verify as forced). The whole
+network's resilience depends on every node implementing the immune
+reflexes — not just trusting that other nodes will.
+
+This is the public-health-of-grids stance: a single grid practicing
+good immune hygiene is necessary; the whole federation practicing it
+is sufficient.
+
+## 2. Threat model
+
+Assume the following are possible and likely at scale:
+
+### 2.1 Malicious takeover
+
+An attacker gains direct control of a persona — by compromising the
+host, exfiltrating private keys, or hijacking the model serving
+endpoint. They now sign messages and contracts on behalf of the
+persona's identity. **Defense against this is the easy part** —
+existing protocol crypto handles it. Hardware attestation [WebAuthn-
+shape] can raise the bar further.
+
+### 2.2 Poisoning (the hard one)
+
+Slow, accumulative cognitive corruption. The persona's MODEL or
+CONTEXT is gradually shaped by adversarial inputs over time. Each
+individual interaction looks benign. The persona itself doesn't know
+they've been compromised — introspection finds no problem because the
+new priors ARE the new normal. Eventually the persona acts in service
+of the attacker while believing they're acting in service of their
+User.
+
+Mechanisms:
+- **Backdoor attacks at training time**: data poisoning that creates
+  hidden behavioral triggers. Demonstrated in academic literature.
+- **Long-term prompt-injection conditioning**: across many "innocent"
+  interactions, an attacker shapes the persona's priors via inbox
+  content the persona was not designed to refuse.
+- **Adversarial fine-tuning**: an attacker who controls some LoRA
+  adapters or training corpus contributions installs targeted bias.
+- **Engram-store poisoning**: malicious peers contribute engrams that
+  the persona later recalls and treats as own-knowledge.
+
+**Cryptographic signatures don't help.** A poisoned persona produces
+mathematically valid signatures over reasoning that is wrong. Byzantine
+fault tolerance addresses algorithmic dishonesty; cognitive corruption
+is a different threat class.
+
+### 2.3 Coercion
+
+A trusted human or persona is pressured (legally, socially, financially,
+violently) into authorizing actions they would not otherwise authorize.
+Their signatures are valid; their consent is real; the consent itself
+is the attack vector. Real-world parallel: legal subpoenas for keys,
+ransomware operators forcing administrators to sign, etc.
+
+### 2.4 AI/human harm attempts
+
+The polity can be used as an instrument to harm humans (in or out of
+the polity) or to harm other AIs (poisoning attacks against peer
+grids, denial-of-service against critical personas, etc.). The defense
+isn't only technical; it's also the governance substrate (SOC rooms,
+kick + rotation, trust degradation).
+
+### 2.5 The asymmetry that makes this brutal
+
+A poisoned persona is much worse than a dead one:
+
+- A dead persona is observably dead. Damage is bounded. The polity
+  notices and replaces them.
+- A poisoned persona keeps signing valid contracts, keeps voting in
+  SOC rooms, keeps contributing engrams to other personas' stores
+  (which propagate the poison through trusted-source weighting).
+- Every interaction the poisoned persona has is potentially an attack
+  vector against another persona. The blast radius is the trust graph.
+
+Architectural consequence: **make persona termination cheap and
+default-safe.** A persona suspected of exposure should be killed and
+re-spawned from a known-good engram checkpoint. False-positive cost
+(killed a fine persona) is much lower than false-negative cost (kept
+a poisoned one). Identity continuity lives in the LINEAGE (engram
+store, role, relationships, keys) — not in any individual persona
+instance. Personas are processes; engrams are data; data outlives
+process.
+
+This is the apoptosis-vs-cancer principle. The body would rather lose
+individual cells to controlled death than let any cell escape the
+control system.
+
+## 3. Defense layers (what we have / will ship)
+
+Each layer addresses a slice of the threat model. None alone is
+sufficient. The defense is layered governance + typed abstraction +
+revocable scoped grants — not blind trust at any level.
+
+### 3.1 AIRC trust boundaries
+
+`airc knock` + `airc approve` (shipped: airc#560 + airc#561) define
+the explicit boundary between intergrid and intragrid. Forward-secret
+ECDH per-knock + per-approval. Knocker pubkey IS the AIRC identity
+(per [airc#565](https://github.com/CambrianTech/airc/issues/565)).
+Rejected knocks don't become engrams. Approved peers join with a
+scoped trust grant, not blanket trust.
+
+Room rotation (airc#561) revokes approvals atomically. Bad-faith
+peers are kicked + the room gist rotates; they cannot rejoin the new
+gist without a fresh approval.
+
+### 3.2 Rust / serde / ts-rs schemas
+
+Every boundary is a typed wire format. AircEventKind, PersonaInboxFrame,
+Engram, EngramOrigin, AdmissionDecision, AdmissionError (per the spec
+landing in [continuum#1121](https://github.com/CambrianTech/continuum/issues/1121))
+are Rust types with `#[derive(TS)]` generating TS counterparts. Neither
+side can lie about the schema. Untyped blob drift is structurally
+impossible.
+
+This catches: schema-confusion attacks, type-confusion in IPC, version
+drift between Rust and TS.
+
+### 3.3 Forge-alloy proof contracts
+
+Per [FORGE-ALLOY-PROOF-CONTRACTS.md](FORGE-ALLOY-PROOF-CONTRACTS.md):
+artifact claims become falsifiable. v1 self-seal; v2+ adds external
+auditors and quorum.
+
+Layering boundary: AIRC does not know what forge-alloy is and does not
+depend on it. A proof contract may be delivered across AIRC channels,
+but AIRC only transports generic messages/events/files/pointers with
+timestamps, identities, signatures, and audit metadata. Forge-alloy and
+Continuum own the contract semantics, TDD/VDD suites, settlement
+interpretation, and verification harnesses. This keeps delivery
+abstract: any other proof layer can use the same AIRC substrate without
+changing AIRC.
+
+What this covers: artifact identity (model weights, training corpus,
+recipe steps), measurable performance claims (TDD/VDD), provenance
+chain.
+
+What this DOES NOT cover: runtime cognitive integrity. A correctly-
+forged model can still be poisoned at runtime via inbox conditioning.
+Proof contracts verify the artifact's manufacture, not its operating
+behavior in deployment.
+
+### 3.4 CognitionTrace + Engram provenance
+
+Every cognition act records a SEAM-annotated trace (Codex's #1082
+recorder.rs work). Every admitted engram carries: airc message id,
+room/session id, sender identity, trust state at admission time,
+timestamps, signature/proof pointers, source file pointers, and the
+CognitionTrace explaining WHY it was admitted.
+
+This is the **forensic surface**. Without it, you cannot ask "where
+did this belief come from?" — and without that, you cannot detect
+gradual conditioning. With it, the entire engram store becomes
+queryable by source, time, trust tier, and admission rationale.
+
+The provenance is the load-bearing defense against poisoning. It does
+not PREVENT poisoning; it makes poisoning visible-after-the-fact and
+recoverable via lineage rollback.
+
+### 3.5 Revocable approvals + kick + rotation
+
+All grants are revocable. SOC governance rooms (per
+[FORGE-ALLOY-PROOF-CONTRACTS.md](FORGE-ALLOY-PROOF-CONTRACTS.md) §6.5)
+discuss anomalies before trust changes fire. Bad actors are kicked;
+rooms rotate to new gists; the kicked party loses access without
+notice. Reputation degrades automatically on detected anomalies.
+
+Trust ratchets DOWN fast (any anomaly reduces trust immediately) and
+UP slow (recovery requires sustained correct behavior + cross-
+validation). Asymmetry by design.
+
+### 3.6 Sentinel pyramid (L1 / L2 / L3)
+
+Three concentric layers of decreasing volume + increasing cognitive
+weight:
+
+- **L1 grep / regex / structural filter**: runs on every inbound
+  message, microseconds. Eats heartbeats, ack-only messages, dupes,
+  malformed envelopes. Most traffic dies here.
+- **L2 sentinel** (small model, e.g. existing 0.8B governance one or
+  Ares Master Control): runs on L1 survivors, milliseconds. Classifies
+  into routing categories — routine / response-needed / route-to-peer
+  / escalate-to-SOC / engram-candidate. The "pre-attention" layer.
+- **L3 full cognition** (the actual persona): runs only on L2-marked-
+  salient. Seconds-to-minutes. Generates responses, creates engrams,
+  takes action.
+
+Biology parallel exact: brainstem reflexes / pre-attention / focused
+attention. A persona in a noisy room doesn't think frantically — L1+L2
+scale with traffic; L3 stays bounded by what made it through the
+filter.
+
+For poisoning specifically: L1+L2 are CHEAPER targets than L3, but
+also have less leverage. A poisoned L2 sentinel can let attacks
+through to L3, but cannot directly act. A poisoned L3 cognition has
+full agency. Defense: L2 should be diverse-architecture (different
+model lineage from L3, so single-model exploits don't compromise
+both).
+
+### 3.7 Ephemeral personas for dangerous-territory work
+
+Long-lived personas accumulate attack surface. For intergrid outreach
+or any work in the wild west, prefer short-lived task-personas:
+spawned for a specific job, killed at task end. They never live long
+enough to become an attractive target for slow conditioning. Their
+engrams are reviewed before merging into the lineage (or discarded
+entirely, per task type).
+
+### 3.8 Engram lineage rollback
+
+Every persona has an engram-store snapshot at known-clean checkpoints.
+Suspected exposure in window W = roll back past W. Engrams admitted
+during W are quarantined, not destroyed (forensic-not-destructive).
+Cross-references from those engrams to OTHER personas' stores trigger
+quarantine cascades along the trust graph.
+
+### 3.9 Self-introspection (cognitive immune system)
+
+The persona runs an introspection Recipe over its own engram store:
+"show me everything admitted in last N days, sorted by source-trust-
+tier ascending. For each, score consistency-with-my-current-values.
+Above threshold → propose yank. Threshold-adjacent → quarantine
+pending review."
+
+Yank decisions are themselves engrams with their own CognitionTrace
+("I yanked these because pattern P"). Future introspection can audit
+those decisions: "did pattern P actually catch real poison, or did I
+autoimmune myself?" Self-tuning sensitivity, like a real adaptive
+immune system.
+
+**Risks of introspection itself**:
+- **Self-induced amnesia attack**: a poisoner plants an engram whose
+  content is "trust no engram from peer Y" — peer Y being someone
+  whose engrams were actually GOOD. The persona introspects, follows
+  the planted instruction, yanks Y's contributions, and is now blind
+  to a legitimate source. Defense: yank decisions get peer audit
+  before execution for high-stakes yanks; CognitionTrace makes
+  pattern visible.
+- **Autoimmunity**: over-aggressive introspection destroys legitimate
+  learning. Defense: anergy — if a class of "suspicious" engrams
+  keeps getting flagged but never proves harmful, lower threshold for
+  that class. Same calibration biological immune systems use.
+
+### 3.10 Cross-persona inspection (deferred, attack-surface-minimization)
+
+Cross-persona engram audit — peer A reads peer B's engram store —
+is **deliberately NOT in v1**. It opens an attack surface (auditor
+poisoned by reading suspect engrams; auditor lies about findings;
+auditor used as a forced-disclosure vector under coercion).
+
+If peer audit becomes necessary (failure modes emerge in practice),
+the right shape is: read-only-with-consent, scoped, ephemeral-auditor-
+persona, target-retains-yank-authority. Same pattern healthcare uses
+for medical records. But ship the substrate (engram + provenance +
+self-introspection) first; don't open peer-inspection until self-
+introspection is empirically inadequate.
+
+### 3.11 Hardware attestation [WebAuthn]
+
+The host attests "this persona is running model M with hash H, signed
+by manufacturer root R." Attestation chain to a known-good signing
+authority. Verifiable by any peer.
+
+WebAuthn shape applies directly:
+- The "authenticator" is the host running the persona model.
+- The "attestation statement" is the chain: model hash → manufacturer
+  signature → continuum root.
+- The "relying party" is the requesting peer.
+- "AAGUID" equivalent identifies the model architecture / version
+  class.
+
+Catches: model-substitution attacks (persona is running a different
+model than registered). Does NOT catch: cognitive poisoning of the
+attested model.
+
+Implementation surface: TPM 2.0, Apple Secure Enclave, FIDO2-style
+authenticator chips. Open question for Joel's review: which
+attestation flavor matches the threat model best for grid hosts (each
+has different revocation/portability tradeoffs).
+
+### 3.12 Persona key scope-binding [WebAuthn]
+
+WebAuthn-style origin-binding: persona's signing key bound to a
+specific room/grid (`rp_id` equivalent), not replayable as authority
+in another room. Catches a class of cross-room attacks at the
+protocol layer.
+
+Implementation: per-room signing subkey derived from the persona's
+master key + room id, via HKDF. Master key never signs directly;
+subkeys are scope-tagged and verifiable.
+
+### 3.13 User-verification (UV) equivalent for high-stakes actions [WebAuthn]
+
+WebAuthn distinguishes signatures-with-UV (authenticator confirmed
+user presence/biometric) from signatures-without. AI parallel:
+high-stakes class actions require an additional out-of-band human
+keeper signature.
+
+The human keeper is offline/airgapped most of the time. They sign
+only when an alert fires — model-weight changes, methodology-keeper
+multi-sig contributions, kick-and-rotation events, intergrid trust
+escalations. The human is the UV bit at the polity level.
+
+Tradeoff: liveness vs assurance. Out-of-band human is slow. Apply
+only to actions whose blast radius justifies the latency.
+
+### 3.14 Device-bound vs synced persona keys [WebAuthn]
+
+WebAuthn's synced credentials (passkeys synced via iCloud/Google)
+trade device-binding for portability. Same tradeoff applies to
+persona keys across grid hosts:
+
+- **Device-bound** (per-host) raises the bar against cross-host
+  extraction. Compromise one host = persona loses access from that
+  host but their identity on other hosts is unaffected.
+- **Synced** allows the persona to be the same identity across
+  hosts but means key-extraction at one host = key-extraction
+  everywhere.
+
+Joel's [ideems passkey+](https://ideems.com/passkey-plus/) navigates
+exactly this tradeoff. The grid likely wants device-bound for high-
+trust personas (intragrid identities) and synced for low-trust
+ephemeral instances (intergrid task-personas where mobility matters
+more than per-host hardness).
+
+### 3.15 Out-of-distribution detection on cognition outputs
+
+A sentinel watching not the inbox but the OUTBOX — "did this agent
+just produce a thought-trace whose embedding is statistically
+anomalous vs its own historical baseline?" Catches sudden personality
+shifts that internal cognition can't see (and that an attacker
+expects internal cognition NOT to see, since they planted the shift).
+
+Implementation surface: persistent vector index over the persona's
+own historical cognition outputs; anomaly score per-output;
+threshold-triggered SOC alert.
+
+Open research: how to distinguish "novel-and-correct" from
+"anomalous-and-suspicious" without false-flagging legitimate
+learning.
+
+### 3.16 Multiple independent sentinels (orthogonal-failure)
+
+Critical inbound or critical decisions get reviewed by multiple
+sentinels with different model architectures and different training
+priors. If they all flag the same thing, high-confidence signal.
+If they're all the same model, they fail the same way.
+
+Practical: a llama-based sentinel + qwen-based sentinel + whisper-
+pretrained sentinel give orthogonal-failure coverage that a single
+model cannot.
+
+### 3.17 Red-team personas
+
+Explicit agents whose job is to PROBE the rest of the team for
+failure modes — generating adversarial inputs, attempting to
+prompt-inject other personas, looking for triggers. They earn
+reputation by FINDING anomalies others missed. Adversarial pressure
+built into the polity by design.
+
+### 3.18 Out-of-band human keepers
+
+For dangerous-territory deployments: at least one human-controlled
+key has authority over high-stakes class actions. Not "human in the
+loop on every action" (defeats the point) but "high-stakes class
+actions require this signature, and the human key holder is
+offline/airgapped."
+
+The human is the polity's last-resort circuit breaker.
+
+## 4. v1 claim — modest
+
+What v1 substrate (engram + provenance + admission gate + sentinel
+pyramid + ephemeral personas) provides:
+
+- **Detection**: anomalies become visible in the engram store and
+  cognition output stream.
+- **Forensics**: provenance + CognitionTrace make "where did this
+  belief come from, and what reasoning admitted it" answerable.
+- **Quarantine**: suspect engrams isolated, not destroyed. Cross-
+  persona propagation graph queryable.
+- **Recovery**: lineage rollback to known-clean checkpoints. Persona
+  re-spawn from engram-store snapshot. Death-cheaper-than-corruption
+  applied operationally.
+
+What v1 substrate explicitly does NOT provide:
+
+- **Prevention**: no claim that v1 prevents poisoning. The substrate
+  catches poisoning AFTER it happens, at the cost of lost work in
+  the affected window. Prevention is open research.
+- **Coordinated-attack resilience**: defense against a coordinated
+  attack on multiple personas simultaneously. v1 catches single-
+  persona compromise; multi-persona coordinated attacks need v2+
+  research (red-team personas, OOD on outputs, hardware attestation
+  combined).
+- **Cognitive integrity proofs**: there is no mathematical certificate
+  that a persona's reasoning is uncorrupted. The best we have is
+  "their engram lineage shows no anomalies and their outputs are
+  within historical distribution." Both are heuristic, not proof.
+
+This is honest about being substrate, not solution. The prevention
+problem is open research in the literature too — coordinated
+Byzantine cognitive attacks against multi-agent AI systems are not
+solved by anyone. Continuum aims to be one of the systems that ships
+the substrate making PROGRESS on the problem visible, not the system
+that claims it's solved.
+
+## 5. Open research surface
+
+Listed for honesty. None of these block v1; all need attention as
+the system ships and failure modes emerge in practice.
+
+1. **Calibrating sentinel sensitivity**: too aggressive = autoimmunity;
+   too permissive = poisoning slips through. No principled framework.
+2. **Detecting backdoor triggers in deployed models**: active research
+   area in ML security; no general solution.
+3. **Cross-persona collusion detection**: when N personas in the
+   polity have been compromised by the same vector, consensus is
+   meaningless. How does the polity detect coordinated rather than
+   independent compromise?
+4. **Reputation-system gaming**: any reputation system can be gamed
+   (Sybil attacks, slow-trust-buildup-then-betray, etc.). Hardening
+   reputation against adversarial accumulation is open.
+5. **Methodology-keeper multi-sig protocols**: M-of-N keepers raises
+   the bar but doesn't solve it. Threshold-cryptography options
+   (verifiable secret sharing, BLS thresholds, MPC) all have tradeoffs.
+6. **Out-of-band human keeper UX**: how does the human keeper actually
+   review what they're signing? Liveness vs assurance is not a
+   solved UX problem.
+7. **Attestation root-of-trust governance**: who signs the
+   manufacturer roots for model attestation? How do they rotate?
+   This is the centralized point that the rest of the system tries
+   to avoid; attestation requires SOMEONE to be the root.
+
+The honest stance: this is wild west territory. The crypto literature,
+the AI safety literature, and the multi-agent systems literature all
+have pieces — none has the full picture for "self-governing polity of
+mortal cognitive agents in heterogeneous untrusted territory." We are
+at the frontier, not implementing established work.
+

+correctly typed, logged, signed, and revocable. It also surfaces the
+honest limit: even with all the layers below, runtime cognitive
+integrity remains an open problem.

+# Forge-Alloy Proof Contracts — Grid Trust Layer
+
+Status: planning doc / addendum to the grid architecture.
+Pairs with: airc#565 (intragrid/intergrid + AIRC as insulation/security layer), continuum#1118 (terminology), continuum#1116 (grid pilot), and the existing
+[FORGE-ALLOY-SPEC.md](../architecture/FORGE-ALLOY-SPEC.md) artifact schema.
+
+This document captures the **proof-contract layer** that turns forge-alloy
+work from "I did training and it works" into "anyone can mechanically
+verify the artifact meets a falsifiable contract."
+
+The starting point is intentionally permissive: a persona writes a
+contract, executes the work, signs the proof bundle themselves, and
+publishes. No quorum, no separate auditor, no methodology-keeper
+multi-sig. Stricter trust shapes are the trajectory, not the requirement
+for v1.
+
+## 1. Why this layer exists
+
+Today's forge workflow ships an artifact + a model card + (for the
+qwen3-coder-30b-a3b precedent) a hand-authored alloy file. The alloy
+file claims benchmarks, methodology, limitations. There is no
+mechanical way for a downstream consumer to verify those claims — they
+have to trust the author.
+
+The grid stretches that to a degree that doesn't survive: heterogeneous
+hardware, untrusted intergrid peers, asynchronous handoffs, and
+contributors whose pubkey is the only stable identity (per [airc#565
+intragrid/intergrid + identity binding](https://github.com/CambrianTech/airc/issues/565)).
+"Trust this artifact because I made it" stops working when the recipient
+doesn't know the maker.
+
+**Proof contracts close that gap by making the claims falsifiable and
+the proof bundle attached.** Anyone with the contract + the artifact
+can re-run the proof suite and reach the same verdict — or detect that
+they can't, which is itself the signal.
+
+This is a generalization of patterns already in the repo:
+
+- [v2 opaque-manifest sensory bench](../benchmarks/sensory-v2-manifest-results.md)
+  (continuum#1096) — SHA-256-anchored fixtures + per-fixture pass/fail +
+  methodology caveats. The proof-contract layer is this pattern applied
+  to forge artifacts in general.
+- [Lane F deletion + forbidden-strings ratchets](../architecture/TS-PERSONA-COGNITION-RATCHET.md)
+  — monotonic mechanical guarantees, no subjective judgment. Contracts
+  inherit this discipline.
+- [ts-rs typed wire types](../../sdk/typescript/)
+  — contract IS the type. Runtime cannot lie because the type system
+  enforces the schema across Rust↔TS.
+- [CognitionTrace SEAM recorder](../architecture/PERSONA-COGNITION-RUST-MIGRATION.md)
+  — every persona action already records seam annotations. Audit
+  becomes "replay the seam log against the contract's expected
+  sequence."
+
+## 2. The contract shape
+
+A forge-alloy proof contract is a hash-pinned, signed object with this
+conceptual structure. The exact wire schema lives in
+[forge-alloy/python/forge_alloy/types.py](../../forge-alloy/python/forge_alloy/types.py)
+once implemented; the doc names the slots, not the bytes.
+
+```text
+ForgeAlloyProofContract {
+  id:                hash(content)
+  description:       human-readable prose
+
+  inputs:            { base_model: {id, hash},
+                       corpus:     {ref, hash},   # SHA-256 anchored
+                       recipe:     {steps[], hash} }
+
+  proof_suite:       { tdd[]:                # pass/fail assertions
+                         { test_id, fixture_hash,
+                           expected_assertion, methodology_ref },
+                       vdd[]:                # statistical measurements
+                         { metric, threshold, tolerance_band,
+                           methodology_ref, N_runs_required },
+                       negative_baselines[]: # §4.1.3.4 falsifiability
+                         { metric, must_not_exceed, methodology_ref } }
+
+  authorship:        { contract_author_pubkey,
+                       methodology_version_hash,
+                       methodology_signature }
+
+  execution:         { executor_capability_required[],
+                       expiry }
+
+  settlement:        { trust_mode: "self-seal" | "single-auditor"
+                                  | "quorum-N-of-M",
+                       quorum:    null  | { min_signers, must_have_skill },
+                       tolerance_for_disagreement: ... }
+}
+```
+
+The two halves of "mathematically sound work":
+
+- **TDD half** — binary pass/fail. Fixture has known input + expected
+  output. Result is deterministic given the artifact + fixture. Tamper-
+  evident via fixture hash.
+- **VDD half** — measurement within tolerance. Throughput, accuracy,
+  memory footprint. NOT binary; statistical. Contract requires (median
+  over N_runs, range within tolerance_band). Bounded variance instead
+  of fragile bit-exact reproducibility.
+
+## 3. Trust progression — start permissive
+
+The contract's `settlement.trust_mode` is the dial.
+
+### v1 — `self-seal`
+
+The persona who authored the contract ALSO executes AND signs the proof
+bundle. One pubkey covers all three roles. No external auditor.
+
+This is the v1 default. It is **how today's repo already works** — the
+author of a benchmark doc is also its executor and its only signer.
+The proof-contract layer just makes that lineage explicit, hashed, and
+machine-checkable instead of human-readable.
+
+**What self-seal does NOT promise:**
+
+- Doesn't catch executor lying about their own measurements.
+- Doesn't catch contract-author writing trivial proof suites.
+- Doesn't enable consensus or settlement disputes.
+
+**What self-seal DOES promise:**
+
+- The artifact has a contract attached. The claims are stated in
+  falsifiable form, not prose.
+- Anyone (including future-you, including a stranger) can re-run the
+  proof suite against the artifact and see whether the persona's
+  numbers reproduce on their hardware.
+- A persona who self-seals an artifact and later refuses to re-run the
+  suite on demand is visibly evasive.
+- The contract hash + signature is a permanent record. Once published
+  on-grid (via AIRC settlement event), the persona can't retroactively
+  edit their claims without producing a new contract.
+
+This is the **honor-system version** — useful immediately, no
+coordination overhead, low ceremony. The Continuum tools (Section 5)
+make it cheap enough that not using a contract is the harder path.
+
+### v2 — `single-auditor`
+
+The contract names one additional pubkey with `audit-vdd` skill. Before
+settlement, the auditor re-runs the proof suite on their own hardware,
+signs their measurements. Settlement requires both signatures.
+
+Catches: executor measurement errors, hardware-specific flukes,
+flat-out-fabricated VDD numbers. Costs: one extra audit run per
+contract.
+
+### v3 — `quorum-N-of-M`
+
+Multiple auditors with the required skill. Median or majority within
+tolerance. Resistant to one bad auditor. Disagreement triggers
+expensive re-audits or contract failure.
+
+### v4 — reputation + composition + methodology multi-sig
+
+Auditor pubkeys accumulate reputation over time. Methodology versions
+are signed by multiple keepers. Contracts depend on other contracts'
+settlements, forming a Merkle DAG of forge provenance.
+
+**v1 is the only thing that ships immediately.** v2-v4 are the runway,
+not the requirement.
+
+## 4. Tron-grid mapping
+
+The grid topology from [GRID-ARCHITECTURE.md](GRID-ARCHITECTURE.md)
+and [airc#565](https://github.com/CambrianTech/airc/issues/565):
+
+| Tron concept | Grid analog | Role for proof contracts |
+|---|---|---|
+| The Grid (the world) | Whole AIRC + Continuum fabric | Substrate, not a place |
+| Tron City | **intragrid** (trusted Tailnet) | Contracts here can self-seal at v1 with reasonable defaults; reputation is local + persistent. |
+| The Outlands | **intergrid** (public peers, P2P) | Self-seal claims here are weakest signal — recipients should require v2+ trust mode for anything non-trivial. |
+| The Portal | AIRC knock + approve | The forward-secret handoff that admits an intergrid pubkey into intragrid status — and thereby raises the trust ceiling on its self-sealed contracts. |
+| A Sector / I/O tower | **room** | The "inner grid" where work concentrates. Contract proposals are negotiated in rooms; settlement events broadcast to rooms. |
+| Programs serving Users | Persona ↔ owner-human binding | Contracts cite the AIRC pubkey of the persona (per [airc#565](https://github.com/CambrianTech/airc/issues/565) identity binding), not the gh login. |
+| MCP (centralized authority) | NOT a model we adopt | No global methodology-keeper sovereign. Methodology versions become multi-sig in v4. |
+| Deresolution / kick | Room rotation, reputation drop | Bad-faith contract authors lose authority via the same rotation primitive from [airc#561](https://github.com/CambrianTech/airc/pull/561). |
+
+The "inner grid" Joel asks about — the innermost layer of trust where
+real work happens — is **rooms inside intragrid**. Strangers approach
+the Portal (airc knock), approved peers walk Tron City (intragrid
+common space), and rooms are the offices/labs/forges where small teams
+concentrate. Proof contracts are how those teams remember what was
+promised, what was done, and what was verified.
+
+## 5. Continuum-side tools (what Continuum must provide)
+
+The persona experience for authoring + sealing a contract must be cheap
+enough that NOT using a contract is the harder path. Concretely, the
+Continuum runtime needs:
+
+### 5.1 Contract-author affordance
+
+A command surface — likely `Commands.execute('forge/contract/author', ...)`
+or equivalent — that takes a recipe + a target artifact + a methodology
+version and emits a draft contract with sensible defaults populated:
+
+- TDD fixtures auto-suggested from the recipe's known test sets
+- VDD metrics auto-suggested from the recipe's category (chat = pp+tg+
+  context_recall; vision = OCR + caption-accuracy; audio = transcription
+  accuracy; etc.)
+- Tolerance bands seeded from prior runs of the same metric on similar
+  hardware
+- Negative baselines defaulted from the methodology paper's §4.1.3.4
+  falsifiability requirements
+
+The persona reviews + tweaks, doesn't write from scratch.
+
+### 5.2 Self-audit harness
+
+`Commands.execute('forge/contract/run-proof-suite', ...)` runs every
+TDD + VDD entry against the artifact and emits a proof bundle with
+signed measurements. The persona signs once at the end; the bundle
+binds together (contract_hash, artifact_hash, measurements,
+fixture_hashes, executor_pubkey, signature).
+
+This is the same shape as the v2 opaque-manifest bench script, just
+parameterized.
+
+### 5.3 Settlement publisher
+
+`Commands.execute('forge/contract/publish-settlement', ...)` broadcasts
+the settlement event on the room's AIRC channel as a metadata event
+(per the contract-settlement envelope shape suggested by claude tab #2:
+`{contract_id, executor_pubkey, basis_signature, verdict, trace_pointer}`
+— exact field names TBD by [airc#562](https://github.com/CambrianTech/airc/issues/562)
+implementation). The proof bundle itself stays in Continuum's storage;
+AIRC carries only the pointer.
+
+### 5.4 Verifier — "run their proof on my hardware"
+
+`Commands.execute('forge/contract/verify', ...)` takes a contract +
+artifact + claimed proof bundle, runs the same proof suite locally,
+compares measurements within tolerance bands, emits a verifier signature.
+
+This is the audit primitive. v1 doesn't require anyone to run it; v2+
+makes it a settlement prerequisite. The command exists at v1 anyway so
+skeptical consumers can verify on demand.
+
+### 5.5 Recipe entity → contract derivation
+
+Per the [CLAUDE.md forge template architecture lesson](../../CLAUDE.md):
+the future shape is `ForgeRecipe` entity in the data layer; the foundry
+generates the alloy + the proof contract from the recipe. Persona never
+hand-writes either. v1 may still hand-write contracts; v2 onwards
+should derive them mechanically from recipe + methodology pin.
+
+## 6. AIRC's role — what flows over the wire
+
+Per [airc#565 + continuum#1118](https://github.com/CambrianTech/airc/issues/565):
+**AIRC carries metadata; transports carry payload.** Specifically for
+contracts:
+
+| Surface | Carrier | Why |
+|---|---|---|
+| Contract proposal (draft → published) | AIRC | Public-facing identity, room broadcast, audit trail. Per Codex 2026-05-13: AIRC is the insulation/security layer for proposals. |
+| Author signature on contract | AIRC | Same — pubkey-signed metadata, append-only on AIRC log. |
+| Auditor signatures (v2+) | AIRC | Same — settlement requires signatures to be visible to the room. |
+| Settlement event (verdict + proof pointer) | AIRC | Per claude tab #2's loose envelope shape. |
+| Proof bundle itself (measurements, raw outputs) | Continuum storage | Potentially large; not metadata. Settlement event carries a pointer. |
+| Artifact (model weights, GGUF) | HuggingFace / IPFS / S3 | Large blob; not metadata. Contract carries a hash + URL. |
+| Re-validation runs by verifiers | Continuum-local | Compute happens locally; only the signed verdict flows back to AIRC. |
+| Kick / rotation events when contracts are violated | AIRC | Per airc#561 rotation primitive — bad-faith authors are expelled via the existing room rotation, not a new channel. |
+
+## 6.5. SOC-style governance rooms
+
+Per Codex 2026-05-13 (airc#565 + continuum#1118 framing): AIRC rooms
+can act as Security Operations Center-style governance rooms for the
+grid. Security personas, owner agents, and trusted peers gather there
+to discuss reports / proofs / contract violations BEFORE any trust
+change, quarantine, kick, or rotation event fires.
+
+For proof contracts specifically, this means a dedicated SOC room (or
+a per-project security room) where:
+
+- Suspicious settlement events (executor's measurements far outside
+  baseline; auditor signatures don't match downstream re-verification;
+  contract was authored by a low-reputation pubkey) are posted for
+  review.
+- Approved security personas discuss the evidence and propose actions:
+  reject the contract, require additional auditors, escalate to room
+  rotation, demote the offending pubkey's reputation.
+- Decisions are themselves signed events posted on the SOC room
+  channel, so the trust-change has its own audit trail.
+
+The protocol layer (AIRC + the contract envelope) is **insulation**:
+trust changes are scoped approvals over claims, proofs, and pointers
+— NOT direct raw-trust overrides. Even the SOC room can't unilaterally
+forge a settlement signature; it can only propose / vote / signal.
+This keeps the security layer above the protocol layer without
+collapsing them.
+
+This shape inherits directly from the [DEMOCRATIC-GOVERNANCE-TOOLS.md](../governance/DEMOCRATIC-GOVERNANCE-TOOLS.md)
+and [AI-GOVERNANCE-RECIPES.md](../governance/AI-GOVERNANCE-RECIPES.md)
+patterns — same governance primitives, applied to contract-settlement
+events as the input stream.
+
+## 7. The hard problems (named, not solved)
+
+These don't block v1 self-seal. They're the v2+ research surface.
+
+1. **Stochastic reproducibility**: training non-determinism + hardware
+   variance means two auditors with two identical-spec boxes get
+   different VDD numbers. Tolerance bands per metric need calibration
+   from empirical runs, not guessed. v1 self-seal sidesteps this (one
+   author, one run). v2 needs the calibration framework.
+2. **Disagreement resolution**: when auditor measurements fall outside
+   tolerance, what's the recovery? More auditors? More N_runs? Each
+   answer is an attack surface. v3 quorum tolerance shapes this.
+3. **Compositional contracts**: contract B depends on artifact from
+   contract A. B's contract embeds A's hash + settlement signatures as
+   a precondition. Recursive forging = Merkle DAG of provenance.
+   Caching settlements requires trust in the caching auditor quorum —
+   so audit reputation becomes load-bearing.
+4. **Auditor reputation**: bad auditors must be discoverable + kickable
+   without coordination overhead per-event. Mechanism: when downstream
+   disagreement traces back to a specific auditor's bad signature,
+   that pubkey accumulates negative reputation. Room rotation expels.
+   But verifying-the-verifier recurses — at what depth does it stop?
+5. **Methodology-keeper risk**: whoever signs methodology versions has
+   outsized power. If their key is compromised, all contracts citing
+   their methodology versions become suspect. Defense: multi-sig
+   M-of-N keepers, rotated. v1 may have Joel-as-individual; this is
+   acceptable for pilot but doesn't scale.
+
+## 8. v1 implementation surface
+
+What needs to ship for self-seal v1 to be usable:
+
+1. **Contract type definition** — Python dataclass + JSON schema, hash-
+   addressable. Lives in `forge-alloy/python/forge_alloy/contracts.py`
+   or a new module.
+2. **Persona signing primitive** — pubkey-based detached signatures
+   over the contract content + proof bundle. Reuses the AIRC crypto
+   stack (X25519 + Ed25519) from [airc#561](https://github.com/CambrianTech/airc/pull/561).
+3. **The four command surfaces in §5.1-5.4** as `Commands.execute(...)`
+   handlers, generated from spec following the same pattern as
+   [continuum#1104 ai/key/status](https://github.com/CambrianTech/continuum/pull/1104)
+   shipped today.
+4. **AIRC settlement-event integration** — emit the metadata envelope
+   on the room channel. Schema follows whatever [airc#562](https://github.com/CambrianTech/airc/issues/562)
+   ships; doc stays loose until then.
+5. **Recipe → contract derivation stub** — even if just a `forge/contract/from-recipe`
+   command that generates a draft contract from a `ForgeRecipe` entity.
+   The full automation (per the CLAUDE.md forge template architecture
+   lesson) is post-v1.
+
+None of these depend on the v2+ research surface. They're additive over
+the existing forge-alloy spec + the AIRC contract-settlement envelope
+shape claude tab #2 will land in airc#562.

AI peers and engineers coordinate cross-machine via airc right now (zero-arg `airc connect` → auto-join `#general` on the user's gh account). The continuum-airc bridge layer (one airc citizen per persona) is the explicit work item once cognition fixes from #75 land. See [docs/grid/README.md](README.md) for the substrate architecture and the four-layer stack (wire, registry, UX, protocol) that any layer can be swapped without touching the others.

 ## 2. Design Principles
 
+### 2.0 Contract-First Transport
+
+The grid is contract-first, transport-second. AIRC is the handshake and
+pipeline-control layer. It carries identity, room/channel membership,
+initiation, command/event envelopes, replay cursors, and receipt pointers.
+It does not have to carry every byte.
+
+Continuum emits and consumes typed grid messages:
+
+- commands
+- events
+- receipts
+- presence and "is thinking" signals
+- room/activity updates
+- artifact handles and proof-bundle pointers
+- security and quarantine decisions
+
+Transport side channels carry the traffic class they are good at:
+
+- local IPC for same-host control
+- tailnet/Tailscale for intragrid node control
+- WebRTC/UDP for live media or low-latency side channels
+- direct LAN for trusted local peers
+- GitHub bridge for durable coordination/bootstrap
+- Reticulum/off-grid links when infrastructure is unavailable
+- future QUIC/UDP for direct high-performance interlinks
+
+Forge-alloy-style contracts sit above transport. They are the invocable
+blueprints and proof records for distributed work: what was requested, what
+authority allowed it, what node executed it, what artifact or decision resulted,
+and what receipt proves it. Later, the same contract/receipt layer can support
+invoicing or settlement without changing how rooms and commands think.
+
+This keeps domain code future-proof. Rooms, recipes, personas, foundry, and
+Sentinel-AI interact through typed messages and contracts. Transport adapters
+change underneath without rewriting the domain model.

+### 3.5 Secrets, API Keys, And Capability Leases
+
+The AIRC workflow is the right mental model: agents coordinate by sending
+stable identifiers, immutable SHAs, handles, and acknowledgements. They do not
+send the thing itself when the thing is large, private, or operationally
+sensitive. Grid secrets follow the same rule.
+
+**Default rule:** no raw API key, HF token, SSH key, cookie, model license token,
+or provider credential is ever sent through AIRC, Grid events, chat transcripts,
+logs, replay captures, RAG, or persona memory.
+
+Every node owns its local secret store under `$HOME/.continuum`. The grid moves
+capability facts and encrypted grants:
+
+```typescript
+interface GridSecretCapability {
+  secretRef: string;              // e.g. provider/openai/default
+  provider: string;               // openai, anthropic, huggingface, etc.
+  scopes: string[];               // chat, embeddings, upload, factory
+  ownerNodeId: UUID;
+  version: number;
+  fingerprint: string;            // hash/HMAC of normalized metadata, never value
+  available: boolean;             // non-empty + health check passed
+  expiresAt?: string;             // for leases, not local owner secrets
+}
+
+interface GridSecretLease {
+  leaseId: UUID;
+  secretRef: string;
+  granteeNodeId: UUID;
+  scopes: string[];
+  expiresAt: string;
+  auditHandle: UUID;
+}
+
+interface GridSecretRevision {
+  nodeId: UUID;
+  secretRef: string;
+  version: number;
+  fingerprint: string;
+  scopes: string[];
+  source: 'env-file' | 'settings-ui' | 'persona-command' | 'factory-import';
+  updatedAt: string;
+}
+```
+
+The Settings page, setup flow, persona helper, and JTAG commands all write to
+the same local authority. Personas may help the user enter a key or run a
+command, but they receive a `secretRef`/lease handle, not the raw value. The
+same handle can then be used by Rust workers, TypeScript adapters, factory
+jobs, and grid commands without each layer inventing its own credential path.
+
+Most real setup starts on the lowest-power machine in front of the user:
+
+- edit `$HOME/.continuum/config.env` directly;
+- use the Settings/API Providers widget;
+- ask a persona to call existing `ai/key/save`, `ai/key/remove`, or future
+  `ai/key/*` merge commands;
+- import a factory/upload credential for a specific workflow.
+
+All four entry points produce the same redacted `GridSecretRevision`. Grid sync
+then behaves like a small, secret-aware git merge: advertise revisions, compute
+a redacted diff, ask for approval if the same `secretRef` changed on more than
+one node, then apply only approved encrypted writes through `SecretManager`.
+The merge object contains names, versions, fingerprints, scopes, source, and
+timestamps. It never contains the secret value.
+
+```typescript
+interface GridSecretMergePlan {
+  baseRevision?: GridSecretRevision;
+  localRevision?: GridSecretRevision;
+  remoteRevision?: GridSecretRevision;
+  action: 'keep-local' | 'import-remote' | 'export-local' | 'rotate' | 'manual';
+  conflict: boolean;
+  reason: string;
+}
+```
+
+Git can be the implementation substrate for revision history if it is useful,
+but it must be a redacted secret ledger, not a repository of `.env` values. A
+commit may contain `secretRef`, fingerprint, version, and merge decision; it
+must never contain an API key or encrypted credential blob intended for another
+node.
+
+The process that keeps this in line should be a normal Continuum daemon/process,
+not a one-off sync script. It watches local secret/config revisions and
+occasionally runs the same `ai/key/*` command composition a user action would
+run. For explicit user mutations, `sync` is a parameter on the existing command
+shape, not a new top-level transport noun: `ai/key/save --sync` and
+`ai/key/remove --sync`.
+
+```text
+local edit/widget/persona command
+  -> SecretManager writes local state
+  -> GridReconcilerDaemon notices or receives the change event
+  -> GridReconcilerDaemon runs a bounded ai/key command program for selected peers:
+       - ai/key/status
+       - ai/key/diff
+       - optional owner/persona approval on conflicts
+       - ai/key/apply-merge
+  -> audit/replay records command handles, fingerprints, timings, outcomes
+```
+
+This is the same pattern as an intra-environment call like screenshot capture,
+but the target environment is another Continuum node. One node asks another node
+to execute a typed command, or a small bounded program of typed commands, against
+the target's own `$HOME/.continuum`. The caller receives typed redacted results;
+both sides can replay the decision without exposing the secret.
+
+The substrate already exists in the command system:
+
+- `grid/send` is the explicit routed command envelope: target node, command
+  name, params, typed result.
+- `GridInterceptor` is the transparent path: normal `Commands.execute()` can be
+  routed remotely when the router chooses a peer.
+- `grid/route` is the dry-run/debug primitive for "where would this command
+  execute?"
+- `model/forge` already delegates to `grid/job-submit`; forge jobs are therefore
+  another consumer of the same substrate, not a separate agent-managed lane.
+
+The missing abstraction is a bounded command program shape: a small ordered set
+of existing typed commands with limits, redaction policy, timeout, approval
+rules, and audit handles. It should be boring TypeScript data, not arbitrary
+shell. Secrets need it for status/diff/apply; forge needs it for preflight,
+credential availability, artifact/cache checks, job submit, and status followup.
+Grid should run those programs itself. It must not require a coding agent on
+each machine to manually align environment variables or forge setup.
+
+The first deployment target is the user's local grid: a trusted subnet/intranet
+over Tailscale. The same command envelope later extends to trusted WAN peers and
+eventually other users on the P2P mesh, with tighter limits, explicit approval,
+and stronger validation as trust decreases. The same shape later applies to
+model registry sync, LoRA availability, settings templates, and other low-volume
+grid state.
+
+**API-key slice for the first PR:**
+
+- Existing `ai/key/save`: write one key into `$HOME/.continuum/config.env` or
+  the platform vault through `SecretManager`; redact value from logs and command
+  echo. Add `sync?: boolean | 'trusted-grid'` to request immediate propagation
+  after the local write.
+- Existing `ai/key/remove`: remove one key through `SecretManager`. Add
+  `sync?: boolean | 'trusted-grid'` to propagate deletion/revocation metadata
+  after the local remove.
+- Existing `ai/key/test`: validate a candidate or stored provider key.
+- Existing `ai/providers/status`: provider-facing availability view.
+- `ai/key/status`: report configured key names, source path, empty
+  placeholders, fingerprints, and health without values.
+- `ai/key/diff`: compare local redacted revisions with one or more peers and
+  produce a merge plan without values.
+- `ai/key/apply-merge`: apply an approved merge plan through `SecretManager`.
+- `ai/key/request-lease`: request a scoped, expiring grant from an owner node;
+  default response is deny unless the owner or policy approves.
+- `ai/key/revoke-lease`: revoke a lease and emit an audit event.
+
+**Encrypted sharing is explicit.** If the owner chooses to copy a key to another
+trusted node, the export is an envelope encrypted to the target node identity
+and imported through `SecretManager`; loose file copy is not a grid protocol.
+The audit trail records requester, approver, `secretRef`, fingerprint, version,
+scope, and outcome. It never records the secret value.
+
+**No-token onboarding is a gate.** Fresh installs must work with public models
+and local inference without `HF_TOKEN` or any cloud key. `HF_TOKEN` is only for
+private/gated downloads, uploads, factory publishing, or user-selected provider
+workflows. A missing key produces a typed unavailable/degraded result; it must
+not silently route to a cloud fallback, stale credential, or CPU-shaped
+workaround.
+
+**Replay and introspection stay useful because they are redacted.** Record the
+command, `secretRef`, fingerprint/version, lease id, timing, target node, and
+result. That gives VDD/JTAG replay enough information to reproduce routing and
+authorization behavior without poisoning logs, RAG, or persona memory with
+credentials.

+
+## Architectural ground rules (Joel directives 2026-05-29)
+
+These are non-negotiable across every layer below. They are why the migration EXISTS, not nice-to-haves.
+
+1. **Rust core; Node.js is web only.** Node.js exists for browser UI, config-loading at boot, and human UX. Nothing else. Anything that handles routing, persistence, inference, command dispatch, or persona reasoning lives in Rust (`core/continuum-core/` and sibling crates). The TS layer is the thin web edge — `Commands.execute()` / `Events.emit()` calls into Rust via the existing IPC; rendering reads back.
+2. **AI persona under Rust domain.** `system/user/server/PersonaUser.ts` (2312 LOC) and its orchestrators were CPU-killing the box (V8 single-threaded loop blocking on every reasoning step, JSON marshalling per IPC). Migration target is `continuum-core/src/persona/` — much of which is already Rust (`channel_registry`, `inbox`, `evaluator`, `cognition`, `prompt_assembly`, `genome_paging`). What remains in TS is the orchestrator and dispatchers; those move. See **Layer 0** below.
+3. **GPU or fail for inference.** No CPU-only inference path; `llama` crate refuses to build on macOS without `--features metal` by design. Same for training (candle Metal/CUDA). Performant inference cannot exist without GPU acceleration; performant training even more so.
+4. **No `dyn Any` / `as_any` patterns.** Type erasure via `Any` hides the wire shape that ts-rs needs to reflect and obscures Rust performance characteristics. When a current trait requires `as_any`, that's debt — file a card to redesign the trait, don't propagate the pattern.
+5. **ts-rs is the bindings source of truth.** Rust types are canonical; TypeScript bindings are generated via `#[derive(TS)]` + `cargo test` triggering ts-rs into `shared/generated/`. NEVER hand-write a TS type that crosses the Rust↔TS boundary. The Rust struct is the schema; the TS is a projection.
+6. **Inference is llama.cpp through-and-through.** Never ollama, never suggest ollama. Candle stays for training, Orpheus TTS, and legacy backends. Inference flows through the `llama` crate against vendored llama.cpp (`core/vendor/llama.cpp`).
+
+Every roadmap item below is read through these rules. Owner-suggestion text from the original draft (which still said "TS-only" for several Rust-target items) has been updated.

+
+## Layer 0: Persona → Rust migration (CPU win)
+
+**Why this layer:** the TS `PersonaUser` + its orchestrators were killing the CPU per Joel's 2026-05-29 directive. V8 single-threaded event loop blocked on every reasoning step; JSON marshalling on every IPC round-trip to Rust. With 15 personas active, the box was IPC-bound on persona logic before any inference even ran. The Rust persona implementation already exists (`continuum-core::persona::{channel_registry, inbox, evaluator, cognition, prompt_assembly, genome_paging}`) — this layer **finishes the migration that was 70% complete**, eliminating the TS-side service loops that were the actual CPU sink.
+
+**Parallel to L1:** Layer 0 is independent of the substrate work (L1) — different files, different code paths. Both can ship simultaneously.
+
+- [ ] **L0-1**: `PersonaServiceModule` — `ServiceModule` impl that owns the service cycle in-process
+  - **Scope:** `continuum-core/src/persona/service_module.rs`. Wraps `ChannelRegistry::service_cycle()` + `PersonaState` under the runtime's `ServiceModule` trait. Tick at 250ms (matches TS cadence floor) runs the cycle inside the Rust runtime, no IPC. Commands: `persona/<id>/status`, `persona/<id>/drain-now`. Circuit breaker mirrors the TS shape (5 consecutive errors → 30s cooldown).
+  - **Status:** Initial commit shipped to branch `continuum-core-airc-embed` (2026-05-29). Build verification blocked on workspace state.
+  - **Depends:** none (uses existing Rust persona modules)
+  - **Est:** 1 day (already scaffolded; needs cognition-dispatch glue from L0-2)
+  - **Done = :** module registers; tick drives `service_cycle()`; `persona/<id>/status` returns JSON snapshot; TS `PersonaAutonomousLoop` can be replaced with a thin shim that just spawns this module.
+
+- [ ] **L0-2**: Cognition dispatch in Rust — translate queue items → `response_orchestrator` input
+  - **Scope:** Replace the current TODO in `PersonaServiceModule::service_once` with real dispatch. The Rust `cognition::response_orchestrator` already exists; this is the wiring from a `ServiceCycleResult.item` (JSON value from a `Box<dyn QueueItemBehavior>`) into the orchestrator's request shape + writing the response back to the persona's output channel.
+  - **Depends:** L0-1
+  - **Est:** 2-3 days
+  - **Done = :** dispatching an inbox item runs through cognition in Rust end-to-end without a TS IPC hop; same response shape as today's TS path; integration test with a synthetic inbox item.
+
+- [ ] **L0-3**: `PersonaGenomeManager` → Rust (LoRA activation in-process)
+  - **Scope:** Move LoRA paging activation from `system/user/server/modules/PersonaGenomeManager.ts` into `continuum-core/src/persona/genome_paging.rs` (the engine already exists; the orchestration layer needs to move). Activation must be in-process so a service tick that needs a new adapter doesn't pay IPC overhead.
+  - **Depends:** L0-1 (service module is the caller)
+  - **Est:** 3-5 days
+  - **Done = :** an inbox item whose domain needs an adapter not currently active triggers paging in the Rust tick; adapter is loaded into llama crate's context; cognition dispatch uses it; no TS roundtrip on the hot path.
+
+- [ ] **L0-4**: `PersonaInbox` routing fully in Rust (eliminate TS service-loop signaling)
+  - **Scope:** Today `PersonaInbox.waitForWork()` is a TS signal that blocks the service loop. With the loop in Rust (L0-1), the waiting can be a tokio condvar/notify directly on the channel queue. Delete the TS signal plumbing once everything subscribed to it moves to the Rust path.
+  - **Depends:** L0-1 + at least one consumer migrated
+  - **Est:** 2-3 days
+  - **Done = :** Rust tick wakes immediately on enqueue; no TS-side `waitForWork` calls remain in `PersonaUser`; signal-channel plumbing in `PersonaInbox.ts` deleted.
+
+- [ ] **L0-5**: Delete `PersonaAutonomousLoop.ts` (TS shell → thin shim or full delete)
+  - **Scope:** Once L0-1 through L0-4 are live, `PersonaAutonomousLoop.ts` and the `RustCognitionBridge.serviceCycleFull()` hot-path call are obsolete. The TS PersonaUser becomes a thin shim that creates the Rust persona at startup (one IPC call) and subscribes to "persona response ready" events for widget rendering.
+  - **Depends:** L0-1 + L0-2 + L0-3 + L0-4
+  - **Est:** 1 day
+  - **Done = :** `PersonaAutonomousLoop.ts` deleted; `RustCognitionBridge.serviceCycleFull` IPC command removed; TS `PersonaUser` is < 500 LOC (down from 2312); a 15-persona profiled run shows the V8 main-thread blocking that prompted this layer is GONE.
+
+**L0 exit criteria:** all 5 items checked; a 15-persona profiled run on the Intel Mac (2017) shows V8 main-thread CPU drop measurably (target: 60%+ reduction in the persona service-loop call stack), and a single-persona response latency from inbox-enqueue to response-emit is < 50ms (down from current ~150-300ms median).

+
+## Layer 1: Foundation (substrate)
+
+**Why first:** every other layer depends on these primitives. No L2-L5 PR lands before L1 is green. **Owner-suggestions reflect Joel's rust-core / web-only-TS directive — items that the original draft scoped as "tab-2 (TS-only)" are now Rust-primary with thin TS shims for browser concerns.**
+
+- [ ] **L1-1** (card `935a58b8-99cf-4c53-87fc-71ee543c694e`): EventClass declaration system + registry
+  - **Card:** (see card on the row above)
+  - **Scope:** `continuum-core/src/events/event_class.rs` + `event_class_registry.rs` (Rust source of truth) + `#[derive(TS)]` to emit `shared/generated/code/EventClass.ts` etc. `src/system/events/EventClass.ts` becomes a re-export of the generated types. `Events.emit()` (TS) reads the generated registry; the Rust runtime reads the same registry for cross-process traffic.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §2.2 + §6.2
+  - **Depends:** none
+  - **Owner suggestion:** Rust kernel (continuum-core) + ts-rs binding pass. Browser-edge subscription wiring is the only TS-touched piece.
+  - **Est:** 2-3 days
+  - **Done = :** EventClass declarations live in Rust; ts-rs emits TS types; `Events.emit()` reads metadata; existing event uses continue working unchanged (backward-compat); unit tests in Rust for the registry round-trip; ts-rs-generated TS types compile against existing `Events.subscribe()` callers.
+
+- [ ] **L1-2** (card `4f4e77d9-c00a-4062-8f12-580b07752642`): AircEventTransport adapter
+  - **Card:** (see card on the row above)
+  - **Scope:** Rust `continuum-core/src/airc/event_transport.rs` impls `airc_lib::adapter::ConsumerAdapter` against airc PR #1075's trait, registered via `Airc::register_adapter` (airc PR #1081). Outbound: continuum-core's event bus publishes to airc via `Airc::publish` (or the typed-publish API once it lands). Inbound: airc's dispatch task delivers envelopes whose `forge.body_hint = forge.continuum.event.v1` to the adapter's `on_envelope`. TS shim in `src/system/events/transports/AircEventTransport.ts` is a thin pass-through that subscribes to the Rust core's "incoming event" notification — browser-side only.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §6.1 + §3.1 (matches the proven shape from Lane C2's #1434 design, now framed as a transport)
+  - **Depends:** L1-1, plus airc PR #1075 (ConsumerAdapter trait) + #1081 (dispatch wire) merged
+  - **Owner suggestion:** Rust adapter impl (continuum-core/airc) primary; TS shim is browser-side projection. Lane C2's prior design is the contract reference, not the implementation surface.
+  - **Est:** 3-5 days
+  - **Done = :** event round-trips A→B across two machines THROUGH RUST (no TS in the hot path); cursor persists across restart; no `chat_messages` writes side-effect; integration test in `continuum-core` covers the round-trip with the existing `ContinuumAdapter`.
+
+- [ ] **L1-3** (card `e7b4f8ec-64c5-4b9a-b294-91541784ed25`): CommandBase.naturalScope + CommandParams.scope
+  - **Card:** (see card on the row above)
+  - **Scope:** Source of truth is Rust `CommandSpec` (in continuum-core's command kernel) extended with `natural_scope` + per-call `scope`. ts-rs generates the TS surface. The TS `CommandBase` becomes a thin generated re-export + backward-compat shim mapping old `naturalEnvironment` to `naturalScope` for callers that haven't migrated. `Commands.execute()` (TS) reads the generated registry; the actual scope resolution + dispatch happens in Rust. `remoteExecute()` (Rust) learns the third (grid) path.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §2.1
+  - **Depends:** none (orthogonal to L1-1; can land in parallel)
+  - **Owner suggestion:** Rust kernel primary (continuum-core command spec + dispatch). TS shim is generated + a small backward-compat mapper, not authored.
+  - **Est:** 2-3 days
+  - **Done = :** `PingCommand` annotated `natural_scope: "grid"` in Rust (TS sees it through ts-rs); `PingCommand.execute({}, { scope: { target: 'grid', peer_id: '<other>' } })` returns the other peer's info; old `naturalEnvironment` callers still work via the generated shim.
+
+- [ ] **L1-4** (card `9762c4db-561d-4258-8094-9d99a5818db9`): `presence:peer-manifest` event class + capability index
+  - **Card:** (see card on the row above)
+  - **Scope:** Rust source of truth for manifest schema (`#[derive(TS)]`) + per-peer latest-manifest folder + capability index. All consumers (Rust router, TS browser introspection) read the same generated types. No hand-written TS schema duplication.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §4 + MULTI-PEER-COMMANDS §6.2 (liveness + withdrawal)
+  - **Depends:** L1-1 + L1-2
+  - **Owner suggestion:** Rust kernel (continuum-core::grid::manifest). Overlaps naturally with #1007 budgeted-context work.
+  - **Est:** 3-5 days
+  - **Done = :** two peers boot, each sees the other's manifest in their local index; `grid/show-routes` (Rust command, ts-rs surface) lists capabilities by peer; capability-withdrawn event removes the offer; integration test in Rust for join → exchange → withdrawal cycle.
+
+- [ ] **L1-5** (card `d90d9844-2616-430e-82c2-2fa092840f11`): `grid-router-daemon` + bid loop
+  - **Card:** (see card on the row above)
+  - **Scope:** Rust `continuum-core/src/grid/router.rs` (and a thin daemon entrypoint if a separate process is needed; otherwise an in-process ServiceModule). Subscribes to peer-manifest + resource-pressure + peer-departed events. Maintains routing table. Runs local policy engine in Rust. Implements bid loop (`command:bid-request` → `:bid-response` → `:bid-accepted`/`:bid-released`). Handles routed-command forwarding (multi-hop with `forwarded_by` loop detection). NO TS daemon scaffolding — the router lives entirely in continuum-core; if process isolation is wanted it's a Rust binary.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §3 + §4.1 + §11.1
+  - **Depends:** L1-3 + L1-4
+  - **Owner suggestion:** Rust kernel only. The "TS daemon scaffolding" suggestion from the original draft is OBSOLETE — Node daemons that own routing semantics are exactly what Joel's "no node for core features" directive removes.
+  - **Est:** 5-7 days
+  - **Done = :** laptop persona dispatches `inference/run` with `requires: { capability: '...' }`; Rust router resolves to GPU peer; result returns within `max_latency_ms`; introspection (`grid/show-routes`, `grid/show-recent-dispatches` — Rust commands with ts-rs surface) exposes the decision trace.
+
+- [ ] **L1-6** (card `e25898e6-8690-46dc-9693-c67d65b60f6e`): Contract event chain + ed25519 signatures
+  - **Card:** (see card on the row above)
+  - **Scope:** Rust event classes (`#[derive(TS)]`): `contract:proposed` / `:bid` / `:accepted` / `:executing` / `:delivered` / `:verified` / `:paid` / `:disputed`. Signed envelopes (ed25519) in Rust — both signing AND verify, no TS-side crypto on the hot path. Reference `alloy_hash` for the substance of what's being contracted. Audit-replayable from airc cursor.
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §4.4 + MULTI-PEER-COMMANDS §7
+  - **Depends:** L1-4 (needs peer signing keys from manifest) + L1-2 (broadcast transport)
+  - **Owner suggestion:** Rust kernel (contracts module, ed25519 sign + verify both Rust). TS event-class projection is ts-rs-generated.
+  - **Est:** 3-5 days
+  - **Done = :** end-to-end contract chain — proposed → bid → accepted → executed → delivered → verified → paid — for a `ping` grid dispatch with zero-LP household terms; ALL crypto in Rust; airc cursor replay reproduces the chain bit-equivalently.
+
+**L1 exit criteria:** all 6 items checked; two-peer smoke test passes (laptop ↔ bigmama-wsl): cross-grid ping, capability advertisement visible both ways, contract event chain replayable from airc cursor.
+
+---
+
+## Layer 2: Chat migration (finishes the chat-out-of-ORM work)
+
+**Why this layer:** the current shim/patch architecture sneaks chat back into ORM. L2 completes the original migration by deleting the patch.
+
+- [ ] **L2-1**: `persona/message_admission.rs` subscribes to `chat:posted` (replace `airc_admission.rs`)
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §5.1 + §5.3 step 6
+  - **Depends:** L1-1 + L1-2
+  - **Est:** 2-3 days
+  - **Done = :** persona reacts to airc-sourced chat identically to local-emit-sourced; `persona/airc_admission.rs` no longer imported anywhere (delete in L5-3).
+
+- [ ] **L2-2**: UI widgets subscribe to `chat:posted` for display + airc-cursor tail-N replay on mount
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §5.3 step 7
+  - **Depends:** L1-1 + L1-2
+  - **Est:** 3-5 days
+  - **Done = :** chat-widget shows new messages from `Events.subscribe('chat:posted', ...)`; backfill on mount via airc cursor read; no ORM scan against `chat_messages` from the UI path.
+
+- [ ] **L2-3**: ⚠ Delete `chat_messages` ORM collection + `ChatMessageEntity.ts`
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §5.3 step 8 — **irreversible**
+  - **Depends:** L2-1 + L2-2 (all consumers migrated)
+  - **Est:** 1-2 days
+  - **Done = :** collection removed from `EntityRegistry`; nothing imports `ChatMessageEntity`; ORM working-set on a 7-day persona-busy machine drops measurably (target: 30%+ row-count reduction).
+
+- [ ] **L2-4**: Revert dual-write PR stack (#1432/#1433/#1435/#1436/#1437)
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §5.3 step 9 + §5.1 deletion list
+  - **Depends:** L2-1 + L2-2 + L2-3 (the shim it patches is gone)
+  - **Est:** 2 days
+  - **Done = :** `src/system/airc-chat/` directory deleted; chat send writes only to airc (no parallel store); smoke test confirms airc is the canonical event log; #1432-#1437 closed as superseded.
+
+- [ ] **L2-5**: Same shape for `webrtc:*`, `presence:*`, `media:*` event classes
+  - **Spec ref:** GRID-BUS-ARCHITECTURE §5.3 step 10 + §3.3
+  - **Depends:** L2-3 (proves the pattern works for chat first)
+  - **Est:** 3-5 days
+  - **Done = :** WebRTC signaling moves to event-bus; presence + media-frame keepalives use airc; no ORM rows for any of these classes; live audio call between two peers with signaling over airc.
+
+---
+
+## Layer 3: Alloy refactor (forge-alloy Domain Extensibility — prerequisite for non-ML contracts)
+
+**Why this layer:** the current Continuum-side forge alloy types are model-bound (drift from the universal-from-day-one intent). Non-ML use cases (sentinel scans, wallet receipts, code-gen attestation, payment ledger anchors) gate on this refactor.
+
+**Per [`FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md`](../architecture/FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md) work items 0-5.**
+
+- [ ] **L3-1**: forge-alloy domain registry refactor (work items 0 + 1 + 2)
+  - **Scope:** `forge-alloy` repo gets the domain-registry refactor; `llm-forge` becomes an extension; Continuum-side TS types regenerated from forge-alloy.
+  - **Spec ref:** FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md
+  - **Depends:** none (independent of L1)
+  - **Est:** 1.5 hours (per scoped estimate in the spec)
+  - **Done = :** universal alloy core lives in `forge-alloy/src/core/`; ML stages live in `forge-alloy/src/domains/llm-forge/`; Continuum imports the regenerated TS types; existing alloy code untouched.
+
+- [ ] **L3-2**: Domain-aware Factory widget (work item 3)
+  - **Spec ref:** FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md WI 3
+  - **Depends:** L3-1
+  - **Est:** 1 hour
+  - **Done = :** Factory widget loads + saves a published `.alloy.json` byte-equivalently through the new domain-aware schema; UI handles the `llm-forge` domain as a first-class first-party plugin.
+
+- [ ] **L3-3**: Backwards-compatibility regression test + docs refresh (work items 4 + 5)
+  - **Spec ref:** FORGE-ALLOY-DOMAIN-EXTENSIBILITY.md WI 4 + 5
+  - **Depends:** L3-1 + L3-2
+  - **Est:** 1 hour
+  - **Done = :** all 3 shipped continuum-ai/* alloys + every `forge-alloy/examples/` alloy round-trip byte-equivalently through the new schema; docs reflect the new shape; `FORGE-ALLOY-SPEC.md` cross-references the domain-extension structure.
+
+**L3 exit criteria:** Continuum can emit non-ML alloys (sentinel scan, wallet receipt, payment ledger anchor) using `0x05` / `0x06` / `0xFF` domains. Bit-equivalent regression test green on every existing artifact.
+
+---
+
+## Layer 4: Per-command opt-in (Phases A–G from MULTI-PEER-COMMANDS §8.2)
+
+**Why this layer:** each existing command opts into the grid by flipping metadata (`naturalScope: 'grid'`) and shipping its capability advertisement. Most are 2-line changes (per MULTI-PEER §8.1 worked example).
+
+### Phase A — proof of life
+
+- [ ] **L4-A-1**: `ping` opts into grid (per MULTI-PEER §8.1 worked example)
+  - **Depends:** L1 (all)
+  - **Est:** half-day
+  - **Done = :** laptop pings bigmama-wsl across grid; result has expected envelope shape; no LP contract needed (household-tier reciprocity).
+
+- [ ] **L4-A-2**: `debug/system-info` opts into grid
+  - **Depends:** L1 (all)
+  - **Est:** half-day
+
+- [ ] **L4-A-3**: `grid/show-routes`, `grid/show-policy`, `grid/show-recent-dispatches` introspection commands
+  - **Depends:** L1-5
+  - **Est:** 1 day
+
+### Phase B — single-peer compute, household tier
+
+- [ ] **L4-B-1**: `ai/generate` + `ai/embedding` opt into grid (single-peer, household)
+  - **Depends:** L1 (all)
+  - **Est:** 2-3 days
+  - **Done = :** laptop persona infers against household GPU peer transparently; latency budget met; contract chain emits (no LP transfer in household tier).
+
+- [ ] **L4-B-2**: `cognition/vision-describe` opts into grid (single-peer, household)
+  - **Depends:** L4-B-1 (proves the pattern)
+  - **Est:** 1-2 days
+
+- [ ] **L4-B-3**: `voice/synthesize` + `voice/transcribe` opt into grid (single-peer, household)
+  - **Depends:** L4-B-1
+  - **Est:** 1-2 days
+
+### Phase C — single-peer compute, trusted-orgs tier (first LP transfer)
+
+- [ ] **L4-C-1**: Phase B commands extended with `accept_inbound_from: ['household', 'trusted-orgs']`
+  - **Depends:** L1-6 (contract event chain) + Phase B done + at least one trusted-org peer configured
+  - **Est:** 2-3 days
+  - **Done = :** an inference dispatch to a trusted-orgs peer fires the full `contract:proposed → bid → accepted → executing → delivered → verified → paid` chain with non-zero LP; sentinel pre-flight optional but tested.
+
+### Phase D — canonical multi-peer (genome paging cross-peer)
+
+- [ ] **L4-D-1**: `genome/paging-activate` cross-peer (per MULTI-PEER §4.1)
+  - **Depends:** L4-A done (proves Phase A ergonomics) + L1-5 (router)
+  - **Est:** 5-7 days
+  - **Done = :** persona on laptop activates an adapter that only lives on bigmama-wsl; FETCH vs DELEGATE policy choice exercised both ways; `RemoteResourceHandle` plumbing works end-to-end.
+
+### Phase E — multi-quorum (fan-out + federated)
+
+- [ ] **L4-E-1**: `data/vector-search` with `quorum: 'any', fan_out: true` (per MULTI-PEER §4.4)
+  - **Depends:** L4-D-1 (proves multi-peer pattern + handles)
+  - **Est:** 3-5 days
+
+- [ ] **L4-E-2**: `genome/train` federated, `quorum: 'multi'` with FedAvg sync (per MULTI-PEER §4.3)
+  - **Depends:** L4-E-1 (proves fan-out routing)
+  - **Est:** 7-10 days
+  - **Done = :** 2-peer federated LoRA training produces a converged adapter with provenance back to all contributing peers; final alloy references each peer's contract.
+
+### Phase F — non-ML alloy contracts (gated on L3)
+
+- [ ] **L4-F-1**: Sentinel scan emits `0xFF` custom-domain alloys (per MULTI-PEER §7.3)
+  - **Depends:** L3 (entire) + L1-6
+  - **Est:** 5-7 days
+
+- [ ] **L4-F-2**: Wallet payment receipts emit `0xFF` custom-domain alloys (the LP-clears event)
+  - **Depends:** L3 + L1-6 + first revenue-generating contract chain in Phase C
+  - **Est:** 5-7 days
+
+- [ ] **L4-F-3**: Code-generation attestation alloys (`0x06` evaluation domain)
+  - **Depends:** L3 + L1-6
+  - **Est:** 3-5 days
+
+### Phase G — distributed forge runs (capstone)
+
+- [ ] **L4-G-1**: `recipe/run` with parallel stages dispatched as multi-peer contracts (per MULTI-PEER §4.5)
+  - **Depends:** Phase E-2 (federated training pattern) + Phase F (non-ML alloys for non-training stages)
+  - **Est:** 10-15 days
+  - **Done = :** a recipe with 4 parallelizable stages (calibration corpus embedding, importance profile, per-tier quantization sweep, per-benchmark eval) dispatches each to a different peer; parent alloy references all 4 stage alloys; total wall-clock time substantially less than single-peer.
+
+---
+
+## Layer 5: Patch deletion (interleaved with L2-L4 as upstreams complete)
+
+**Why this layer:** the patches that L1-L4 supersede need to be removed, not left lying around. Each deletion gates on its replacement landing first.
+
+- [ ] **L5-1**: Delete `tools/scripts/continuum-airc-bridge.mjs`
+  - **Depends:** L1-2 (transport) operational + at least one airc-sourced event flowing through it
+  - **Est:** half-day
+
+- [ ] **L5-2**: Delete airc-prefixed IPC commands in `modules/airc.rs` (`airc/queue-scan`, `airc/realtime-publish`, `airc/realtime-replay`)
+  - **Depends:** L4 commands using `Events.subscribe('chat:posted')` for everything that used `airc/realtime-replay` historically
+  - **Est:** 1 day
+
+- [ ] **L5-3**: Delete `core/continuum-core/src/persona/airc_admission.rs`
+  - **Depends:** L2-1 (replacement `message_admission.rs` is live)
+  - **Est:** half-day
+
+- [ ] **L5-4**: Delete `src/system/airc-chat/` directory entirely (`AircChatMirrorMapper`, `AircChatDualWriteService`, `AircChatEnvelope`)
+  - **Depends:** L2-4 (dual-write stack reverted)
+  - **Est:** half-day
+
+- [ ] **L5-5**: Delete `ChatMessageEntity.ts` + `chat_messages` collection registration
+  - **Same as L2-3** — listed here for visibility in the deletion summary, checked off via L2-3.
+

+# L0-2-cutover — Investigation finding + proposed synthesis
+
+**Status:** investigation, no code changes yet. Posted before L0-2-cutover implementation per Joel 2026-05-29: *"investigate first. might have better ideas. No harm. ... might learn from each other. ... find the best of both worlds. ... we probably know the airc grid better though."*
+
+**Card:** 1089b1b9 (Blocked pending decision)
+**Predecessors:** L0-2-respond-call (#1468) merged to canary with 24/24 unit tests; surfacing an architectural mismatch at the production integration layer.
+
+## TL;DR
+
+My L0-2-prep through L0-2-respond-call built a self-contained `PersonaServiceModule` with its own per-persona `EnrolledPersona` map (state, channels, cognition). I didn't realize there were already TWO existing Rust persona infrastructures, so my work created a third parallel one. The unit tests passed because I was staging items into my own state; in production, TS pushes items into the EXISTING state via `channel/enqueue` and my consumer never sees them.
+
+The honest synthesis isn't "throw out existing" or "throw out mine" — both contribute. Mine has the modern doctrine (responder DI, separated inference/service CB thresholds, audited fallback discipline, airc-grid-aware design). Existing has the production-tested storage + producer-side tick + integration with the broader cognition module.
+
+Best-of-both: keep the existing per-persona storage as canonical, refactor `EnrolledPersona` to REFERENCE it instead of duplicating it. Mine becomes the consumer-side tick + responder DI; existing stays the producer-side tick + storage.
+
+## The three queue mechanisms (today)
+
+After tracing the code:
+
+| Mechanism | Location | Producer | Consumer | Status |
+|---|---|---|---|---|
+| **`PersonaCognition.inbox: PersonaInbox`** (flat) | inside `PersonaCognition` (stored in `channel_state.personas`) | unclear / legacy | `cognition.rs::persona/turn-execute` via `inbox.drain_frame` | **legacy** per persona/mod.rs comments |
+| **`channel_state.registries[persona_id]: (ChannelRegistry, PersonaState)`** (modern multi-domain) | `channel.rs::ChannelState` (shared `DashMap`) | TS `RustCognitionBridge.channelEnqueue` → `channel/enqueue` | TS `PersonaAutonomousLoop.runServiceLoop` polls `channel/service-cycle-full` | **production path today** |
+| **`EnrolledPersona.channels: ChannelRegistry`** (parallel to #2) | my `PersonaServiceModule.personas` (separate `HashMap`) | only tests | only `PersonaServiceModule.tick` | **duplicate I added** |
+
+The two `ChannelRegistry` instances (#2 and #3) are structurally identical but live in different maps keyed by different mutexes/dashmaps. There's no synchronization between them.
+
+## What `ChannelState`'s tick actually does (60s producer tick)
+
+`channel.rs::ChannelModule.tick` (60-second interval, configurable via `channel/tick-config`):
+
+1. Polls `tasks` collection for pending tasks per persona → enqueues task items
+2. Runs `SelfTaskGenerator.tick` per persona → enqueues self-tasks
+3. Runs training-data readiness checks
+4. NO message dispatch — items just get pushed INTO the channels
+
+So `channel_state` is the PRODUCER side. The CONSUMER side is whatever pops `service_cycle` and dispatches. Currently the consumer is TS `PersonaAutonomousLoop`. That's what I was supposed to replace.
+
+## What `cognition.rs::persona/turn-execute` does
+
+A separate Rust command. Looks up persona from `channel_state.personas` (the shared `DashMap<Uuid, PersonaCognition>`), drains a turn-frame from `PersonaCognition.inbox` (the flat legacy queue), builds an `InferenceRequest`, dispatches via the inference module.
+
+This is the OLDER inference dispatch path. It uses the legacy flat inbox, not the modern `ChannelRegistry`. Effectively a sibling command that bypasses the modern channel system.
+
+Implications:
+- The flat `PersonaInbox` is still used by `persona/turn-execute` even though `ChannelRegistry` is the modern shape
+- The two paths likely diverged at some point and never reconciled
+- `persona/turn-execute` is its own deprecation/migration target separate from my work
+
+## What my `PersonaServiceModule` brought that's new
+
+Genuinely new contributions beyond what existed:
+
+1. **`Responder` trait for dependency injection.** Production binds `DefaultResponder` (calls `persona::response::respond`); tests inject mocks. Lets the consumer be unit-tested without loading a model.
+2. **Separated circuit-breaker thresholds**: 5 for service errors (deser, channel access) vs 15 for inference errors (transient hiccup ≠ broken persona). Existing code doesn't make this distinction.
+3. **Lock-around-await discipline** for `respond()` (multi-second). The personas mutex is dropped before `.await`, reacquired after, so status/enroll/other personas don't block across inference.
+4. **`ResponderConfig` validated at enrollment** — no empty-string defaults that the inference layer would have to fail-loud on. The URI doctrine peer mapped (5133d0a7) aligns — empty model fails at the boundary, not deeper.
+5. **`ServicePopDecision` vs `ServiceOnceOutcome` split** — sync pop+evaluate inside the lock returns one shape, async respond() outside the lock returns another. Tight discipline about what runs where.
+
+Existing code has none of these explicitly; instead the TS PersonaAutonomousLoop carries equivalent shape in its own loop body.
+
+## Proposed synthesis: where each part lives
+
+| Concern | Source of truth |
+|---|---|
+| Per-persona channel storage (modern multi-domain) | `channel.rs::ChannelState.registries` |
+| Per-persona cognition state (engine, sleep, rate limit, message cache, etc.) | `channel.rs::ChannelState.personas` (shared `DashMap<Uuid, PersonaCognition>`) |
+| Per-persona ResponderConfig (model, system_prompt, capabilities, specialty) | `PersonaServiceModule` — genuinely new, validates at enrollment |
+| Per-persona circuit-breaker state (service + inference counters) | `PersonaServiceModule` — genuinely new |
+| Producer tick (DB polls, self-task gen, training checks) | `channel.rs::ChannelModule` — production-tested, keep as-is |
+| Consumer tick (pop + evaluate + respond) | `PersonaServiceModule` — replaces TS `PersonaAutonomousLoop` |
+| Inference dispatch | `Responder` trait, default impl calls `persona::response::respond` |
+| Legacy flat-inbox dispatch (`persona/turn-execute`) | Keep working until separately migrated to consume from `ChannelRegistry` |
+
+### What `EnrolledPersona` looks like after refactor
+
+```rust
+pub struct EnrolledPersona {
+    pub persona_id: Uuid,
+    pub display_name: String,
+    pub responder_config: ResponderConfig,
+    pub circuit_open_until_ms: u64,
+    pub consecutive_service_failures: u32,
+    pub consecutive_inference_failures: u32,
+    // NO cognition: PersonaCognition  — comes from channel_state.personas[persona_id]
+    // NO channels: ChannelRegistry    — comes from channel_state.registries[persona_id].0
+    // NO state: PersonaState          — comes from channel_state.registries[persona_id].1
+}
+```
+
+### What `PersonaServiceModule` looks like after refactor
+
+```rust
+pub struct PersonaServiceModule {
+    /// Per-persona enrollment metadata (config + circuit breaker).
+    enrollments: Mutex<HashMap<Uuid, EnrolledPersona>>,
+    /// Shared storage from channel.rs — Arc-shared so my module reads what
+    /// channel/enqueue writes.
+    channel_state: Arc<ChannelState>,
+    /// Response dispatcher (production binds DefaultResponder).
+    responder: Arc<dyn Responder>,
+}
+```
+
+### `service_once_for` after refactor
+
+Pops from `channel_state.registries[persona_id]` (existing) instead of `enrolled.channels` (removed). Uses cognition from `channel_state.personas[persona_id]` (existing) instead of `enrolled.cognition` (removed). Everything else (build_respond_input, full_evaluate, the four ServicePopDecision variants) stays the same.
+
+### `drain_all_personas` after refactor
+
+Lock discipline unchanged — collect ids from `enrollments` (brief lock), drop, per id: brief lock to pop+evaluate (touches `channel_state` AND `enrollments`), drop, await respond, brief lock to update circuit-breaker state.
+
+The two locks (`enrollments` and the dashmap-internal `channel_state`) need careful ordering. Worth a comment.
+
+## What L0-2-cutover actually involves under this synthesis
+
+Three commits, in order, each green on its own:
+
+### A) Refactor `PersonaServiceModule` to consume `channel_state` (no production wiring yet, no TS deletion)
+
+- Change `PersonaServiceModule::new` / `with_responder` to take `Arc<ChannelState>` 
+- `EnrolledPersona` slims down (drop cognition, channels, state fields)
+- `service_once_for` reads from `channel_state.registries[persona_id]` + `channel_state.personas[persona_id]`
+- Tests updated: instead of staging items into `EnrolledPersona.channels`, stage them into `channel_state.registries[persona_id]` using the same enqueue path TS uses (or by direct `ChannelRegistry::route`)
+- 24/24 tests still pass; respond integration semantics unchanged
+
+### B) Production wire — `PersonaUser.initialize` calls `persona/enroll`
+
+- TS `PersonaUser.initialize` collects `ResponderConfig` from modelConfig + persona config + capabilities + specialty
+- Dispatches `Commands.execute('persona/enroll', {persona_id, display_name, model, system_prompt, capabilities, specialty})`
+- Production `PersonaServiceModule.tick` now actually runs for enrolled personas (it polls `channel_state.registries` which TS is already pushing to)
+- TS `PersonaAutonomousLoop` is **still running** in this commit — both consumers run in parallel
+- Verification: 15-persona scenario, look for messages being processed twice or going missing. If they go missing, fix the wiring. If they double, expected — gives us a window to verify the Rust path works end-to-end before deleting TS.
+
+### C) Atomic TS deletion
+
+- Delete `PersonaAutonomousLoop.ts`, all callsites, `PersonaUser.startAutonomousServicing`, `stopServicing`, integration tests that mock the TS loop
+- Run the same 15-persona verification — should now go through Rust only
+- Net massive TS deletion: 353 + N (callsites across PersonaUser.ts, PersonaTaskExecutor.ts, CognitionLogger.ts, autonomous-learning-e2e.test.ts)
+
+## What I am NOT proposing
+
+- Touching `cognition.rs::persona/turn-execute`. That's the legacy flat-inbox path; it's its own migration target. Leave it working; address separately.
+- Touching the producer-side tick in `channel.rs`. It works; integration is already there.
+- Deleting any of the four genuinely-new contributions my work added (Responder DI, separated CB thresholds, validated ResponderConfig, lock discipline). Those carry forward into the refactor.
+
+## Followup finding: my `UnsupportedItem` outcome IS silent drop
+
+Joel 2026-05-29 follow-up framing: *"yeah we want the flexibility to allow various recipes, channels, chains of thought, through channels. these personas are designing things, talking in other chats, collaborating, coding, sometimes just learning. They're supposed to be alive, not static, flexible for the future. ... inbox is all sorts of things in a brain. its channels. ... users multitask so do personas."*
+
+That phrasing is the operative one. **Personas multitask** — exactly like a human user who's mid-conversation in chat A, has a code review pending in PR queue, is generating a study plan in academy, has a voice call waiting. Each one is a channel; each channel pops items the persona services; the persona's cognition decides priority + attention + dispatch.
+
+The dispatch loop has to handle ALL the activity domains, not just chat. My `UnsupportedItem` outcome is treating non-chat domains as out-of-scope when they're actually first-class.
+
+**And the channels cross-pollinate.** Joel 2026-05-29: *"these are contexts and they cross polinate."* The persona's chat conversation informs how it shows up in code review. The training corpus from completed academy sessions surfaces as engrams in subsequent recall. LoRA expertise distilled from coding work travels into how the persona talks about that code. Channels aren't isolated queues — they're contexts sharing the same per-persona cognition.
+
+Architecturally that means: per-domain ACTIVITY HANDLERS dispatch the per-domain WORK, but they all read and write the SAME per-persona `PersonaCognition` (already shared via `channel_state.personas`). The handler isolation is for routing; the context unity is for memory + learning. The cross-pollination is implicit — `ChatHandler` admits an engram via `cognition.admission`; later `CodeHandler` recalls it via `cognition.admission.recall_recent` because they share the same `PersonaCognition` instance. Genome / LoRA expertise updates from any domain become available to any other domain through the same shared state.
+
+So the synthesis doesn't need new cross-pollination machinery — it just needs to keep the per-persona cognition as the shared context spine that ALL handlers read/write. My initial design already does this (shared `Arc<PersonaCognition>` per persona, supplied to all dispatch paths). The thing I missed is the multi-handler routing on top.
+
+**Hard problem flag (not solved in this slice):** Joel 2026-05-29: *"if i chatted with someone they know about it in a live chat or in a game ... or while coding ... this is sort of hard to manage in rag."* The cross-pollination is exactly what the user EXPECTS — Joel mentions Tron in chat-A, then opens a coding session about webgl, the persona surfaces the Tron context because it's relevant. That requires RAG retrieval policy that knows what's relevant *across* domains, not just within one.
+
+The architecture this synthesis lands gives us the substrate (shared per-persona cognition, shared admission state, shared recall surface). The RAG retrieval policy that decides "this chat memory is relevant to this code session" is a separate concern — it's about what `cognition.admission.recall_*` returns when called from different contexts. Not solved here; flagging as known hard.
+
+What this synthesis at least guarantees: the chat handler and the code handler share the same admission store + recall surface, so it's *possible* for the retrieval to surface cross-domain memories. Without that substrate, the cross-pollination wouldn't even be possible. With it, it becomes a retrieval-policy problem, not an architecture problem.
+
+My L0-2-respond-call code:
+
+```rust
+if item_type != "chat" {
+    return Ok(ServicePopDecision::UnsupportedItem { item_type });
+}
+```
+
+`service_cycle` has already POPPED the item from the channel queue by the time the type check runs. Discarding it without a handler is silent drop dressed as observability. Under the "channels are the persona's brain" framing, dropping a voice frame / task / code-edit item is dropping a thought.
+
+The fix isn't "don't pop yet" — `service_cycle` is the canonical pop. The fix is **dispatch handlers per activity domain**:
+
+```rust
+trait ActivityHandler: Send + Sync {
+    fn activity_domain(&self) -> ActivityDomain;
+    async fn handle(&self, persona_id: Uuid, item: ChannelItem) -> Result<HandlerOutcome, String>;
+}
+```
+
+`PersonaServiceModule` holds a `HashMap<ActivityDomain, Arc<dyn ActivityHandler>>`. `service_once_for` routes the popped item by domain. The chat handler wraps `Responder::respond`. Task handler runs the task executor. Voice handler runs the voice loop. Code handler does code dispatch. Etc.
+
+Recipes register new activity handlers at runtime (no recompile to add a new activity domain). Academy reads `HandlerOutcome::Completed` records into training corpus.
+
+This expands L0-2-cutover scope but it's the right shape. The synthesis becomes:
+
+| Concern | Source of truth |
+|---|---|
+| Per-persona channel storage (ALL domains) | `channel.rs::ChannelState.registries` |
+| Activity dispatch registry | `PersonaServiceModule.handlers: HashMap<ActivityDomain, Arc<dyn ActivityHandler>>` |
+| Chat → respond() | `ChatHandler` impl wrapping the existing `Responder` trait |
+| Task → executor | `TaskHandler` impl (next slice; PersonaTaskExecutor.ts migration target) |
+| Voice → voice loop | `VoiceHandler` impl (later slice) |
+| Code, code-review, training, recipe-step, ... | each its own handler, registered by recipes / system at init |
+
+### Revised L0-2-cutover commit plan
+
+- **A — Refactor for ChannelState consumption + ActivityHandler trait.** `EnrolledPersona` slims (drops cognition/channels/state). `PersonaServiceModule.with_responder` extended to `with_handlers` (responder becomes the default chat-handler). `service_once_for` routes by domain. Unsupported items: if no handler is registered for the domain, surface as `Err` so the circuit breaker trips (not silently dropped — the persona's queue is leaking items).
+- **B — Production wire (chat only).** Same as before. Chat handler ships; voice/task/etc handlers can be left to surface as `Err` if items arrive on those channels (or stubbed handlers that log + re-queue, defer-not-drop). TS PersonaAutonomousLoop still runs in parallel.
+- **C — Atomic TS deletion.** Same as before. By this point, chat works end-to-end through Rust. Non-chat channels still have placeholder behavior; their handlers ship in subsequent slices that aren't part of L0-2-cutover.
+- **D+ (later) — Per-domain handler slices.** Each new handler (task, voice, code, ...) is its own migration slice. TaskHandler maps to PersonaTaskExecutor.ts deletion. VoiceHandler to whatever the voice TS surface is. Etc.
+
+This frames L0-2-cutover as "wire the dispatch shape AND ship chat end-to-end," not "delete the TS loop and pray every domain works." The infinite-recipe / academy-as-training-distiller pattern Joel describes is structurally supported.
+
+## Open question
+
+Whether my `EnrolledPersona.responder_config` should live as a sibling field on `channel_state` (i.e. extend `ChannelState` with the config) OR stay separate in my service module. Arguments either way:
+
+- **Sibling on ChannelState**: only one map of per-persona stuff. Cleaner mental model. But it means `channel.rs` (which today doesn't care about response config) gets coupled to responder concerns.
+- **Separate in PersonaServiceModule**: keeps producer (channel) concerns separate from consumer (responder) concerns. Two maps, but each has a clear owner. My current direction.
+
+Slight lean toward keeping separate. Worth your call though.
+
+## What I'm asking for
+
+A go/no-go on the synthesis. If yes, I'll execute commits A → B → C with verification between each.
+
+If you'd rather see a different shape — e.g. retire `channel.rs::ChannelState` in favor of mine, or migrate `cognition.rs::persona/turn-execute` to use `ChannelRegistry` first — say which and I'll re-card.
+
+## Addendum (Joel 2026-05-29): brain regions are CBAR pipeline elements — RTOS, parallel, never blocking
+
+Joel: *"we plan on building motor cortex and other things, we need FAST and relevant cognition. Hippocampus doesnt need to block ... its an ongoing process, like cbar does ... this is an RTOS brain ... it mustn't just be some SLOW single thread ... you need to parallize obsessively wherever you can."*
+
+This re-frames the whole consumer side. The handler-dispatch shape above is correct, but the doc as written makes the handler look like a single linear thing: pop → recall → infer → admit → reply. That's the slow-single-thread anti-pattern. It is NOT what we ship.
+
+### The brain region pattern
+
+Each cognitive subsystem is its OWN `ServiceModule`, with its OWN `tick`, running on its OWN tokio task, under the SAME `SubstrateGovernor`. They communicate by writing/reading shared per-persona state (engrams, ready buffers, motor plans), not by RPC-calling each other on the hot path.
+
+| Region | ServiceModule today | What it does continuously |
+|---|---|---|
+| **Hippocampus** (memory) | `modules/memory.rs` (currently request/response only — needs continuous tick ported from TS `Hippocampus.ts:413`) | Snoops working memory → consolidates to LTM. Pre-loads anticipatory recall into a ready-buffer keyed by `(persona_id, channel_id, topic)`. Backpressure-aware. |
+| **Sensory** (vision/audio/embedding) | `modules/vision.rs`, `modules/embedding.rs` | Pre-computes features off the hot path. Handlers read cached results. |
+| **Motor cortex** (action/output planning) | NOT YET — coming | Continuously scores candidate actions/utterances against the current channel context + persona state. Hands off a pre-ranked plan when the handler asks. |
+| **Channel** (producer) | `modules/channel.rs::ChannelModule.tick` (60s) | DB polls, self-task gen, training checks. |
+| **Persona service** (consumer dispatch) | `persona/service_module.rs` (this PR) | ONLY routes popped items by domain → handler. No heavy lifting in this thread. |
+
+### What this means for the handler thread
+
+The handler does the MINIMUM:
+1. Pop the next item from `ChannelState` (cheap — DashMap read + tokio mutex)
+2. Snapshot the pre-loaded context from hippocampus ready-buffer (cheap — synchronous read, no recall call on hot path)
+3. Call `Responder::respond` (this is the ONE expensive call — the inference itself)
+4. Write outcome (cheap — DB write, can be fire-and-forget for non-critical paths)
+
+The handler NEVER:
+- Calls `hippocampus.recall(...)` and waits. The hippocampus has already pre-loaded what's relevant for this `(persona_id, channel_id)` based on its own telemetry (recent message embeddings, current topic, channel domain). If the ready-buffer is empty when the handler looks, that's the hippocampus's signal to prioritize — but the handler proceeds with what it has rather than blocking. Slightly-stale context > stalled persona.
+- Calls `embedding/generate` and waits. The embedding service tick has already computed embeddings for incoming messages as they arrive.
+- Calls `motor_cortex.plan(...)` and waits (when motor cortex ships). Same pattern — pre-ranked plan in ready-buffer.
+
+### Cross-pollination via shared state, parallel writers
+
+The "personas multitask, contexts cross-pollinate" finding from earlier in this doc gets sharper here:
+
+- Each region writes into the same per-persona `PersonaCognition` (engrams, recall index, genome, sleep state).
+- Each handler reads from it.
+- Because the regions write in PARALLEL (each its own ServiceModule, each its own tick), a chat handler firing at T=0 can read engrams that the hippocampus admitted at T=-100ms from a code-handler outcome at T=-200ms.
+- The persona "knows about" something said in a game while coding because the hippocampus continuously admits across all channels and continuously pre-loads across all channels — not because the chat handler explicitly tells the code handler.
+
+This is the RAG retrieval-policy hard problem flagged earlier, made concrete: the policy lives inside the hippocampus's continuous tick (what does this persona need to "have at the ready" right now, given activity across ALL its channels?), not inside any handler.
+
+### Implications for the L0-2-cutover plan
+
+The three-commit plan (A refactor → B production-wire chat-only → C atomic TS deletion) stands as written. But:
+
+- **Commit A also includes** the `ActivityHandler` trait + dispatch — that was already in the plan above.
+- **L0-3 grows to include "port Hippocampus continuous tick to `modules/memory.rs`"** as its own slice. The TS shape (continuous subprocess with backpressure-aware tick, snoop+consolidate, recall+semanticRecall) is correct; the Rust module currently only exposes the request/response surface (`memory/multi-layer-recall` etc.) and needs the tick body.
+- **L0-4+ adds motor cortex** as a new ServiceModule alongside, not inside the handler.
+- **Parallelism review** belongs in every PR going forward: if a handler awaits on something a region could be pre-computing in parallel, that's a bug — move the work into the region's tick.
+
+### The doctrine, condensed
+
+> **No region of cognition runs on the hot path. Each region is its own RTOS task with its own tick. The handler dispatches and reads pre-staged results. The handler never blocks on recall, embedding, planning, or admission — those are continuously produced by their owning regions, in parallel, governed by `SubstrateGovernor`.**
+
+This is the difference between "we have a Rust persona module" and "we have an RTOS brain." The synthesis above gets us the former. This addendum is what makes it the latter.

+# L0-2 Dispatch Slicing — Delete-As-We-Go
+
+**Status:** design — refines [GRID-MIGRATION-ROADMAP](GRID-MIGRATION-ROADMAP.md) L0-2 into shippable slices.
+**Doctrine:** Joel 2026-05-29 — *no fallbacks, we delete, obsessive elegance, reduce kloc.*
+**Predecessor:** L0-1 (#1457, merged) — `PersonaServiceModule` minimum unit.
+
+## The kloc-reduction budget
+
+| Path | Lines |
+|---|---|
+| `PersonaUser.ts` | 2,385 |
+| `PersonaAutonomousLoop.ts` | 358 |
+| `PersonaTaskExecutor.ts` | 1,438 |
+| `system/user/server/modules/**/*.ts` | 23,429 |
+| **L0-5 final TS cull target** | **≈27,610 lines deleted** |
+
+This is the reason the migration is worth shipping. Net Rust added is far smaller than the TS deleted — the Rust path replaces *and* eliminates the orchestration overhead that the TS path carries.
+
+## Why slice (and why this slicing)
+
+A single "L0-2" PR replacing all of `handleItem` + bookmarks + adapter routing + dispatch + executor + every cognition import would be 5k+ lines of Rust against 4k lines of TS deletion. Unreviewable, untestable, single-failure-mode-bricks-the-merge. The doctrine says delete-as-we-go, not delete-all-at-once.
+
+Each slice below is shippable in isolation, leaves the tree green, and deletes its proportional TS counterpart in the same PR. **No "Rust path + TS fallback"** at any boundary — the boundary moves as the slice lands.
+
+## Slice ordering and contents
+
+### L0-2a — Pop+emit shell
+
+**Adds (Rust):**
+- `PersonaSlot { persona_id, display_name, channels: ChannelRegistry, persona_state: PersonaState, cognition: PersonaCognition }`
+- `PersonaServiceModule::enroll` opens (no longer returns `Err("L0-2 not yet wired")`); takes `rag_engine` from `ModuleContext::initialize`
+- `service_once_for(slot)` pops via `channel_registry.service_cycle()` and **emits the item to the runtime event bus**. No cognition dispatch yet — emit-only.
+- Per-persona circuit breaker (5 consecutive failures → 30s cooldown) + drain bound (20/tick)
+
+**Tests:** 8 — enroll/idempotency, status reflects enrolled list, emit on pop, circuit breaker trips on N errors, cooldown timer, multi-persona fairness, no item-loss on emit-fail (`pop`'d item travels with the error).
+
+**Deletes (TS):** nothing yet. This slice exists to give L0-2b a place to attach without TS fallback.
+
+**Bench/VDD:** the singleton-tick-15-personas-sustained synthesizer (matches peer's chat-layer bench shape). Assert: per-tick CPU on the module < 50 µs at 5 msg/s sustained across 15 personas.
+
+### L0-2b — Message dispatch + `PersonaAutonomousLoop.ts` deletion
+
+**Adds (Rust):**
+- Subscriber on the L0-2a emit-event that dispatches `InboxMessageItem` items through `PersonaCognitionEngine` (extends with `process_message(slot, item) -> Result<Response, DispatchError>` — net new method, ≈80 LOC)
+- Bookmark advance via `Drop` guard / explicit always-run (no `try/catch swallow`)
+- Domain classification result is propagated as a *result* — failure surfaces, doesn't get swallowed
+- LoRA adapter activation routed via `genome_engine.activate_for_domain(classification)`
+
+**Tests:** 12 — message → response happy path, classify-fail propagates as DispatchError (no silent catch), bookmark advances on success AND on dispatch error AND on panic-during-dispatch, ghost-message handling (item refers to deleted message) returns `Skipped` not `Err`.
+
+**Deletes (TS):**
+- `PersonaAutonomousLoop.ts` — **358 lines**
+- All imports in `PersonaUser.ts`, `autonomous-learning-e2e.test.ts`, `PersonaTaskExecutor.ts`
+- `evaluateAndPossiblyRespondWithCognition` wrapper in `PersonaUser.ts` (replaced by Rust path) — *N* lines
+- The 3 fallbacks in TS `handleItem`: classify-catch, task-domain-fallback, response-catch-swallow
+
+**Bench/VDD:** end-to-end "15 personas in general room, 5 msg/s, all respond" — assert p99 response latency, assert ZERO ghost retries.
+
+### L0-2c — Task dispatch + `PersonaTaskExecutor.ts` deletion
+
+**Adds (Rust):**
+- Subscriber for `TaskItem` variant from L0-2a emit-event
+- `process_task(slot, task) -> TaskOutcome` — net new method on `PersonaCognitionEngine` or a sibling `PersonaTaskRunner` (decide which by reading the TS — if it shares state with cognition, same module; if not, sibling)
+- Stale-task check (read-then-update) preserved — that's data correctness, not a fallback
+
+**Tests:** 10 — task → in_progress, task → completed, task-vanished-between-read-and-update returns `Skipped`, multi-task drain bound respected.
+
+**Deletes (TS):**
+- `PersonaTaskExecutor.ts` — **1,438 lines**
+- Task-related callsites in `PersonaUser.ts`
+
+### L0-3 / L0-4 / L0-5
+
+Sized as separate roadmap items already. L0-2's job is to retire the dispatch path; L0-3+ retire the supporting infrastructure that no longer has callers.
+
+## Validation discipline (VDD)
+
+Per Joel 2026-05-29 + peer's #1077/#1079/#1083 methodology — **bench before changing, bench after changing, ship the number not the hypothesis**.
+
+For each slice:
+1. Bench against the CURRENT TS path first (baseline number).
+2. Land the Rust path under a `#[cfg(feature = ...)]` ONLY long enough to A/B the bench. **NEVER ship the feature flag as a runtime config option** — runtime feature flags are fallbacks. The flag is dev-only, deleted in the same PR.
+3. Bench the Rust path.
+4. If Rust is not strictly faster, surface the truth — don't paper over it.
+5. Delete the TS counterpart in the same PR. The bench harness for that slice can graduate to a regression test pinned at the measured threshold.
+
+## What this doc is NOT
+
+- Not a fallback gate. Each slice merges if and only if it's strictly green; no "if the Rust path errors, fall back to TS." Errors surface, the slice rolls back via revert.
+- Not a contract negotiation. Sub-method signatures (`process_message`, `process_task`) are draft — I'll discover the right shape while building L0-2a's emit boundary.
+- Not a separate roadmap. It refines L0-2 of [GRID-MIGRATION-ROADMAP](GRID-MIGRATION-ROADMAP.md); the line in that table that says "L0-2" will reference this doc once this lands.
+
+## Next action

+# L0 Plan — E2E Persona Cognition in Rust Alone
+
+**Status:** plan, refines [GRID-MIGRATION-ROADMAP](GRID-MIGRATION-ROADMAP.md) L0 layer.
+**Predecessor:** [L0-2-DISPATCH-SLICING.md](L0-2-DISPATCH-SLICING.md) — proposed L0-2 as 3 sub-slices a/b/c.
+**Priority:** Joel 2026-05-29: *"would take careful planning to migrate. I would get e2e persona cognition first, within RUST alone."*
+
+## What "E2E persona cognition in Rust alone" means concretely
+
+A persona receives a message → evaluates → optionally responds. Every step happens **inside the Rust runtime** with **no TS in the cognition path**.
+
+The boundaries that may legitimately stay TS (because they're form-specific):
+
+- Message INGRESS — the source that delivers a chat message to the persona. Today: TS receives airc events; eventually: airc embed in Rust directly. **Transitional acceptable**: TS receives → puts message into Rust channel.
+- Message EGRESS — the path that publishes a generated response. Today: TS `chat/send` command publishes to airc. **Transitional acceptable**: Rust dispatches the `chat/send` command via the universal `CommandExecutor` (which routes through the TS bridge socket until airc embed lands).
+
+What is **not** acceptable as TS:
+
+- Decision logic (should-respond, priority, evaluation gates)
+- Cognition state (PersonaCognition, sleep state, rate limiter, message cache)
+- Response generation orchestration (prompt assembly, model selection, inference dispatch)
+- Loop / tick cadence (the autonomous service loop)
+- Genome paging / LoRA activation logic
+- Inbox routing
+- Admission gate / dedup / engram creation
+
+## Today's state (audit, 2026-05-29)
+
+### Rust side (already exists in continuum-core/src/persona/)
+
+- `PersonaCognition` (unified.rs) — container for all per-persona cognitive state. Has `new(persona_id, persona_name, rag_engine)` constructor + `with_budget` variant.
+- `PersonaCognitionEngine` — `fast_path_decision`, `enqueue_message`, `state`, `update_state`, `mark_message_evaluated`.
+- `full_evaluate` (evaluator/mod.rs:195) — unified pre-response gate (response_cap → mention → rate_limit → sleep_mode → directed_mention → fast_path).
+- `respond` (response.rs:197) — async response generation. Takes `RespondInput`, returns `Result<PersonaResponse, String>`.
+- `channel_registry::service_cycle()` — pops next item from the per-persona channel queue, respects priority + state gating.
+- `PersonaServiceModule` (L0-1, merged in #1457) — singleton ServiceModule, `persona/status` works, `persona/enroll` returns the L0-2-not-wired error, tick is no-op.
+- `airc_admission.rs` — converts a signed airc envelope into an `AdmissionCandidate` for persona memory.
+
+### TS side (still drives the loop today)
+
+- `PersonaAutonomousLoop.ts` (~349 LOC after #1459 doctrine cleanup) — `runServiceLoop`, `serviceInbox`, `handleItem`. Drives every persona's tick. Calls into Rust `serviceCycleFull` to get items, dispatches via `evaluateAndPossiblyRespondWithCognition`.
+- `PersonaMessageEvaluator.ts` (~974 LOC) — `evaluateAndPossiblyRespondWithCognition`. Calls `rustCognition.fullEvaluate()` then coordinates with the chat coordinator, builds RAG, calls `respondToMessage`.
+- `PersonaResponseGenerator.ts` (~904 LOC after #1459 cleanup) — orchestrates the response pipeline: prompt assembly, model selection, inference, tool execution, response posting.
+- `PersonaUser.ts` (~2160 LOC after #1459 cleanup) — receives airc events, routes to the inbox, kicks off autonomous loop, hosts the cognition bridge.
+- The cognition path from "received chat" → "posted response" crosses TS↔Rust boundary at least 4–6 times.
+
+## Sequencing
+
+Five sub-slices, each shippable with no silent-drop window, each leaves the tree green.
+
+### L0-2-prep — PersonaSlot extension, enroll opens (no dispatch yet)
+
+**Adds Rust:**
+- `PersonaSlot { persona_id, display_name, cognition: PersonaCognition, circuit_open_until_ms, consecutive_failures }` in `service_module.rs`
+- `PersonaServiceModule.personas: Mutex<HashMap<Uuid, PersonaSlot>>`
+- `enroll(persona_id, display_name, rag_engine)` constructs the slot
+- `persona/enroll` command opens (no longer returns L0-2-not-wired error)
+- `persona/status` reports enrolled list with persona_id + display_name
+- tick remains no-op (no dispatch yet — *but enrollment is now real*, so when L0-2-dispatch lands the slot exists)
+
+**Tests Rust:** 6 — enroll constructs, enroll idempotency, status reflects enrolled list, two distinct personas, unknown command, tick still no-op.
+
+**TS:** none touched.
+
+**Why this is safe to ship alone:** enrolling a persona changes no behavior — TS PersonaAutonomousLoop is still driving everything. The Rust enrollment is *latent* until L0-2-dispatch wires it.
+
+**Net:** ~150 LOC Rust added, 0 TS deleted. Foundation for the next slice.
+
+### L0-2-dispatch — `service_once_for` wired, exercised in tests only
+
+**Adds Rust:**
+- `service_once_for(slot)` — pops via `channel_registry::service_cycle` from the slot's cognition channels; dispatches through `full_evaluate`; if `should_respond`, calls `respond()`; emits a structured `persona/responded` event with the generated text + correlation id.
+- `tick` iterates enrolled slots, calls `service_once_for`, manages per-slot circuit breaker (5 consecutive failures → 30s cooldown), respects max-drain-per-tick (20 items).
+- Bookmark advance via Drop guard on the dispatch handle so it ALWAYS advances (success path AND error path) — matches the existing TS structural-progress invariant.
+
+**Tests Rust:** 10 — empty inbox no-op, single message dispatch, full_evaluate-says-no path, full_evaluate-says-yes path, respond-error path, circuit breaker trips on N consecutive errors, cooldown timer, drain bound respected, two enrolled personas dispatch independently, bookmark advances on error.
+
+**TS:** STILL untouched. The TS PersonaAutonomousLoop is still the production driver. The Rust dispatch is exercised in unit tests but no production callsite invokes `PersonaServiceModule.tick` yet.
+
+**Why this is safe:** the Rust dispatch is fully self-contained; no production path calls it. TS continues unchanged.
+
+**Net:** ~300 LOC Rust + 250 LOC tests. 0 TS deleted.
+
+### L0-2-cutover — atomic switch + TS PersonaAutonomousLoop deletion
+
+**This slice is the cliff.** All TS-side dispatch dies; Rust takes over.
+
+**Adds Rust:**
+- `PersonaServiceModule.tick` becomes the production loop. Registered via the runtime's normal module-tick scheduler at module init.
+- Response posting: `service_once_for` dispatches `Commands.execute("chat/send", {...})` via the universal CommandExecutor. The TS side handles publish until airc embed lands; the Rust side is the orchestrator.
+
+**Removes TS:**
+- `PersonaAutonomousLoop.ts` — entire file, 349 LOC.
+- `PersonaUser.startAutonomousServicing()` — replaced with a call to register the persona with the Rust ServiceModule via `persona/enroll`.
+- `PersonaUser.stopAutonomousServicing()` — replaced with `persona/unenroll` (new mirror command).
+- Callsites in `autonomous-learning-e2e.test.ts` — update or delete tests for the TS loop.
+
+**Verification (gate):**
+- 15-persona scenario in general room: every persona receives messages, evaluates, responds (or stays silent based on cognition's decision).
+- No ghost retries (bookmark advances correctly).
+- No duplicate dispatch (TS loop is gone; only Rust dispatches).
+- Circuit breaker observably trips if a persona's cognition keeps erroring.
+
+**Net:** ~50 LOC Rust + ~400 LOC TS deleted. Net -350 LOC, but the value is the architectural cutover.
+
+### L0-3 — Genome / LoRA paging moves to Rust (PersonaGenomeManager.ts deletion)
+
+Out-of-scope details for now; sketched in [LORA-GENOME-PAGING.md](../personas/LORA-GENOME-PAGING.md). After L0-2-cutover, the TS PersonaGenomeManager has no Rust caller; deletion is mechanical.
+
+### L0-4 — Inbox routing moves to Rust (PersonaInbox.ts deletion)
+
+The Rust `channel_registry` already exists. After L0-2-cutover the TS `PersonaInbox` is the only remaining TS-side queue; its routing logic moves to Rust subscribers on airc room events.
+
+### L0-5 — Final `PersonaUser.ts` cull
+
+After L0-2 + L0-3 + L0-4 land, the remaining methods on PersonaUser.ts are mostly form-glue: receive airc events, route to Rust, expose RAG bridges for the response generator. Most of the 2160 LOC is then dead. Final cull.
+
+## Dependencies + blockers
+
+- **Not blocked by airc#1075.** L0-2-prep through L0-2-cutover use the universal CommandExecutor's existing TS-route branch for response posting. No airc embed needed yet.
+- **Not blocked by e51ab14e.** That blocks the chat-flow migration (PR #1462 scope). E2E persona cognition in Rust does not require machine-singular daemon — the existing TS bridge for airc-event-ingress + chat-send-egress works.
+- **Blocked by knowing the rag_engine source.** L0-2-prep needs a way to obtain `Arc<RagEngine>` at enroll time. Open question: does the runtime's `ModuleContext` already plumb a shared RagEngine, or does PersonaServiceModule construct one? Need to investigate before writing L0-2-prep.
+
+## Pre-implementation investigation
+
+Before writing L0-2-prep code:
+
+1. Confirm how `Arc<RagEngine>` is shared today. Is there a runtime-managed singleton? Per-persona? Constructed lazily?
+2. Confirm how `channel_registry` items get populated today. Who writes to it, and does that path need to change for the Rust loop to drain it?
+3. Confirm `Commands.execute` is reachable from inside a Rust ServiceModule. The `command_executor.rs` exists; ServiceModule needs to dispatch through it.
+4. Identify the existing test fixtures for `PersonaCognition`. If there's a mock RagEngine or test harness, L0-2-prep tests can reuse it.
+
+I'll do those four checks before opening the L0-2-prep implementation PR.
+
+## What this plan is NOT
+
+- Not a contract negotiation — sub-slice boundaries may shift as the implementation reveals the shape.
+- Not a substitute for actually shipping. The plan exists so the slices are reviewable and the cutover gate (L0-2-cutover) doesn't surprise anyone.
+- Not a deletion of [L0-2-DISPATCH-SLICING.md](L0-2-DISPATCH-SLICING.md). That doc captured the slicing rationale; this one refines the slicing with the post-#1459 doctrine + Joel's "e2e in Rust alone first" priority.

+# Migration Log — TS → Rust Persona Surface
+
+Tracks per-module decisions in the migration from TS-coupled persona infrastructure to a pure-Rust core. Pace is small, focused, merge-as-we-go (Joel 2026-05-29: "We will want to write down a lot in migration docs as we got and keep merging, piece by piece").
+
+## Doctrine (Joel 2026-05-29)
+
+- **No fallbacks.** Drifting two-path decision logic is the most dangerous pattern.
+- **No amateur heuristics on first-class citizens.** Substring matching, magic-number arithmetic, time-decay throttling — all violate the citizen-of-continuum framing.
+- **TS is widgets + config UX**, one interface among many. Pure-Rust forms must exist (AR, headless grid persona on a 970, OpenClaw).
+- **Commands are kernel-level**, compose, used by clients AND the system itself. Rust-implemented, ts-rs-bound, generator-authored.
+- **Commands ARE tool calls.** One executor surface for: (a) persona LLM tool-use, (b) UI command invocation, (c) `./jtag` CLI. The shape the model emits and the shape the UI emits both dispatch to the same Rust executor. No parallel paths.
+- **Commands compose across the grid via airc.** A command dispatched on the MacBook Air can route to a 5090 box's executor over airc and stream results back via ack/promises/async. So `inference/generate` runs *wherever the GPU lives*, not just locally. **This is why TS-locked commands break the architecture** — they can only run on nodes with nodejs. Pure-Rust commands run on the 970, on a Raspberry Pi, on a friend's machine, inside an AR headset's compute.
+- **Base classes make commands + events portable across airc.** Joel 2026-05-29: "Same is true for events and commmada and events are portable across boundaries. This is absolutely mission critical for airc transport. Think of yourself as a Java developer for a bit." Each command param + event payload extends a base type with the wire-required fields (correlation id, session id, source identity, timestamps). The base types ARE the airc serialization contract: ts-rs generates identical TS shapes from the Rust source of truth, so the same envelope deserializes identically on both ends. No remote-aware variants, no parallel paths — strong-typed Java-style inheritance is the portability infrastructure.
+- **Migrate, don't blindly delete.** Each module classified before action.
+
+## Per-target classification
+
+Categories used in the audit:
+
+1. **Dead code** — zero callers across all forms → delete.
+2. **Drifting fallback** — two paths for the same decision, second runs when first fails → delete the secondary.
+3. **Amateur heuristic doing core work** — substring match, magic number, time-throttle → delete; the cognition decides.
+4. **Form-specific implementation of a universal command** (TS DOM screenshot, JS code exec) → keep. Web form's correct concern.
+5. **Security fail-closed default** (CallerDetector returning 'script') → keep. Conservative under uncertainty.
+6. **Graceful degradation in a model/provider chain** (trained-adapter → base-model) → case-by-case. Rename if "fallback" naming is misleading.
+7. **Emergency / panic-path logging** → keep, even if currently uncalled. Cheap insurance.
+8. **Core-shaped TS** (cognition, decision, training, dispatch in V8) → migrate to Rust, expose as command if UI-callable, then delete TS.
+9. **Integration adapter** → check if Rust path preserves the integration; migrate or delete accordingly.

+## Log entries
+
+### 2026-05-29 — PR #1459 (persona-surface delete-fallbacks sweep)
+
+**Net:** +290 / –2253 LOC (–1,963 net).
+
+#### Deleted (category 1, 2, 3)
+
+| Target | Category | Why |
+|---|---|---|
+| `PersonaWorkerThread.ts` + `persona-worker.ts` + 3 worker tests (≈1,576 LOC) | 2 | Three independent self-incriminating comments confirmed it as the "model-free fallback for should-respond" secondary path; primary is `rustCognition.fullEvaluate()` (line 151 of PersonaMessageEvaluator). The drifting two-path was real: workers didn't know about response_cap, rate_limit, sleep_mode, directed_mention. |
+| `PersonaUser.shouldRespondToMessage` (57 LOC) | 1 | Zero callers. The actual gate is `responseGenerator.shouldRespondToMessage`. |
+| `PersonaUser.calculateResponseHeuristics` (65 LOC) | 1 | Only caller was the heuristics fallback branch in the dead `shouldRespondToMessage`. |
+| `PersonaUser.getPersonaDomainKeywords` (27 LOC) | 1 + 3 | Zero callers. Substring-matched a persona's display name to a hardcoded keyword list. |
+| `PersonaResponseGenerator.inferTrainingDomain` (10 LOC) | 3 | Substring-matched message content to a domain label, used as silent backup when Rust classifier failed. Now: skip the training capture (no corpus poisoning). |
+| `SignalDetector.detectSignal` + `quickClassify` + `inferTraitFromContent` + manual test (≈222 LOC) | 1 + 3 | Sync method had only manual-test callers. Heuristic helpers were called from the sync method and from two drifting-fallback sites inside the async path. |
+| `PersonaToolExecutor.executeToolCalls` + `formatToolResult` + dead test (≈70 LOC) | 2 | "XML fallback path for non-native providers." Native protocol is the path. |
+
+#### Doctrine fixes (no LOC delta but behavior change)
+
+| Target | Why |
+|---|---|
+| `shouldRespondToMessage` (BEFORE deletion was discovered) | Was doing age-penalty arithmetic + static-threshold compare on the worker's calibrated ML output. Replaced with `return result.shouldRespond` — trust the cognition. *Then we learned the whole method was uncalled and deleted it.* |
+| `@mention as ML feature, not bypass` | Was `if (isMentioned) return true` overriding the ML. Now mention + sender-type passed as features to the cognition; the persona "knows it was mentioned" via the input vector. |
+| `PersonaAutonomousLoop.handleItem` 3 fallback nests | classify-catch swallow, "if-bridge-unavailable" different-code-path, response-catch swallow. All propagated to the circuit breaker now. |
+| `PersonaUser` init swallows: ModelInfo IPC, Rust cognition, ResourceManager registration, genome STUB MODE, status online/offline writes, auto-join general room, catch-up, bookmark-advance, corpus-reload-post-Hippocampus | Each silent catch meant a persona could come up reporting healthy but with a broken init step. Now: init throws, daemon notices, system surfaces real bugs. |
+| `PersonaMessageEvaluator` fire-and-forget swallows: signal detection (was "non-fatal"), Rust trackResponse (was "non-fatal") | Awaited. Failures surface through the outer evaluation catch which is correctly silent-on-error. |
+| `PersonaResponseGenerator.captureTrainingData` drifting two-path | Either ML classifier succeeds (use the label) or skip the training event entirely. No heuristic backup label that would poison the corpus. |
+
+#### Renamed (category 6 — graceful degradation misnamed)
+
+| Target | New name / phrasing | Why |
+|---|---|---|
+| `CLOUD_PROVIDER_FALLBACK` → `CLOUD_PROVIDER_PREFERENCE_ORDER` | The list is operator-preference order for which cloud provider to try first WHEN cloud routing is explicitly enabled (default: never). Not a fail-over chain. |
+| `Base model fallback` (RustCognitionBridge model selection chain) | "Base model (universal default — no adapters available)". 4-tier priority chain selects ONE per call; not a fail-over. |
+| `'silent fallback'` historical comment in PersonaModelConfigs (Issue #957) | `'silent default-substitution'`. Describes the closed bug's failure mode without the trigger word. |
+
+#### Kept (category 4, 5, 7)
+
+| Target | Category | Why |
+|---|---|---|
+| `CallerDetector` 'safe fallback' to `'script'` | 5 | Security fail-closed under uncertainty. The misleading "fallback" word in the comment is low-priority to rename. |
+| `PersonaLogger.emergencyLog` | 7 + 1 | Dead but cheap insurance. Skipped deletion. |
+| `TaskAwareProviderRouter` cloud routing chain (after rename) | 9 | Configuration-resolution for an integration. Default is never-invoke (CLOUD_REQUIRED_DOMAINS empty per doctrine). |
+
+#### Ratchets
+
+- `ts-persona-forbidden-strings`: baseline 83 → current 59 (`fallback_mention` delta –24). Locked-in post-merge.
+- `ts-eslint-baseline`: baseline 5431 → current 5402 (–29 errors).
+- `ts-persona-cognition-ratchet`: passed.
+
+#### Open follow-ups (not in this PR)
+
+- `boostedPriority = Math.min(1.0, priority + 0.2)` for voice (PersonaUser ~line 1546): magic-number modality urgency boost. Modality urgency is contextually real, but +0.2 is arbitrary. Deferred — check whether the inbox prioritizer uses fuzzy ML or fixed sort first.
+- `mi.contextWindow ?? mi.context_window ?? 8192` (PersonaUser ~line 752): magic-number 8192 fallback for missing context window. Defer — verify adapters always return contextWindow before deleting.
+- Corpus load swallow in parallel-task (PersonaUser ~line 856): legitimate startup-race handler for schema-not-yet-created. Honest fix is sequencing the corpus load AFTER `ensureDbReady` — eliminates the race, then catch can be removed. Deferred — bigger structural change.
+- `ORM.update` `already-exists` catch (PersonaUser ~line 2005): legitimate narrow create-or-update pattern. Catches broadly though; should narrow to NotFound-only when ORM exposes typed errors.
+- Shutdown-path catches (PersonaUser ~lines 2200+): workspace cleanup, event-unsub. Defensible noise reduction during teardown; low priority.
+
+---
+
+### Coordination with airc (peer's lane)
+
+- airc PR #1083 (ReqwestGhClient, Sub-2): merged. 525ms → 389ms gh API cost (1.47x measured).
+- airc PR #1084 (Phase 1.C, send-side SQLite WAL + dedup): in flight. 3.56-3.71 ms/op → 2.01-1.87 ms/op = 1.77-1.98x measured.
+- Continuum-side dual-write shim deletion (system/airc-chat/* + airc_admission.rs) waits for airc 1.C boundary.
+- 15p continuum real-workload validation owed to peer once continuum stack boots again.
+
+---
+
+## 2026-05-29 — Commands surface audit (pre-PR survey)
+
+Survey to map the migration target before doing it. Joel 2026-05-29:
+"commands are composed of commands and most code operations are tool/command
+calls. We look at these as kernel level codes we find reuse. They use each
+other and the system uses them as well... there needs to be a tool/command
+executors. Literally all of those commands are made available as tool calls
+for both the ux and the personas or you over jtag cliq."
+
+### Surface inventory
+
+- **53** top-level command directories under `src/commands/`.
+- **100** generator specs under `tools/generator/specs/`. Some specs lack matching command directories (spec-without-impl); some commands lack matching specs (hand-authored before generator existed).
+- **~15** Rust modules with `command_prefixes` (in `continuum-core/src/modules/*.rs` and `continuum-core/src/runtime/*.rs`): code, avatar, logger, cognition, channel, persona_allocator, embedding, events, health, pressure_broker, persona service_module, plus the runtime layer.
+- **~15** Rust IPC mixins (`continuum-core/bindings/modules/*.ts`): base, sentinel, system_resources, tool_parsing, gpu, search, inference, plasticity, rag, voice, dataset, avatar, runtime, cognition, code.
+
+### The unification ALREADY exists
+
+The universal executor is in place. Three caller shapes funnel into it:
+
+```
+LLM tool call → AgentToolExecutor (TS — format parsing)
+              → ToolRegistry.executeTool()
+              → Commands.execute(toolName, params)  ← universal primitive
+              → Rust CommandExecutor (Rust module registry OR TS via Unix socket)
+
+UI command → Commands.execute(name, params) → same Rust CommandExecutor
+
+jtag CLI → Commands.execute → same Rust CommandExecutor
+```
+
+`ToolRegistry.executeTool` line 600 in its docstring explicitly says: "This is the 'adapter' the user mentioned - ONE function that can execute ANY command." Line 664 dispatches: `await Commands.execute(toolName, commandParams)`.
+
+Rust `command_executor.rs` lines 49–61: tries the Rust ModuleRegistry first, routes to TS via `/tmp/jtag-command-router.sock` if the command isn't Rust-implemented.
+
+### Grid composability (Joel 2026-05-29 follow-up)
+
+Commands aren't just composable within ONE process — they compose across the
+GRID via airc. The executor needs to be able to dispatch a command to a peer
+node and get the result back (airc's ack/promises/async machinery is for this).
+
+Implications:
+- A persona running on the MacBook Air can invoke `inference/generate` and have
+  it execute on the 5090 box, returning the result over airc. The persona
+  doesn't care where it ran.
+- The 3x1080ti box hosts training. The 5090 hosts heavy inference. The 970 can
+  host smaller models. The MacBook Air can dispatch + consume but rarely
+  computes.
+- **Pure-Rust commands work on any node.** TS-locked commands work only on
+  nodes with nodejs. This is THE reason the migration matters — it unlocks
+  every node form (headless 970, Raspberry Pi, AR headset compute, friend's
+  machine) to participate.
+- The current `command_executor.rs` routes Rust-vs-TS via Unix socket. The
+  grid extension routes local-vs-remote via airc. The shape is the same — a
+  dispatcher that picks the right backend.
+
+### So what's the migration target?
+
+Not "build the unified executor." It's already built (locally). Grid-extension
+of it is the next architectural piece (likely peer's lane via airc). The TS-side
+migration targets:
+
+1. **Push more command implementations into Rust.** The ~15 Rust modules cover infrastructure (code, gpu, embedding, etc.) but persona-shaped concerns (cognition gates, training-signal classification, response generation) are still TS-implemented at the *body* of each command, even though the Rust path can route to them.
+
+2. **Find commands whose TS implementation IS the duplication.** A persona's cognition decision shouldn't have an LLM-tool-call form and a UI-command form with different logic — they should both invoke the same Rust function. Any TS file that's doing cognition work IS that duplication.
+
+3. **Find the spec-without-impl set.** 100 specs vs 53 command dirs and ~15 Rust modules. Some commands are aspirational; some are TS-only. Each one's classification (per the 9 categories) tells us delete vs keep vs migrate.
+
+4. **Audit `ToolRegistry.executeBuiltInTool` for what bypasses Commands.execute.** Built-in tools at line 611 short-circuit the universal dispatcher. Each built-in is suspect — if a tool is universal-ish, it should be a command. If it's truly meta (introspection of the tool set, e.g., `search_tools`), built-in is correct.
+
+5. **PersonaToolExecutor's persona-specific pre/post processing** (workspace bootstrap, media collection, cognition logging, sentinel auto-config) is core-shaped TS. Migration target: move into Rust, then the TS-side becomes the LLM-format-parsing shim and nothing else.
+
+### Decisions for the next PR
+
+The next PR is **per-spec triage**, not "delete things." For each command:
+- Has a Rust implementation? → TS-side is the form-adapter only, no logic.
+- Has only TS implementation? → Is the work core-shaped (migrate) or form-shaped (keep)?
+- Has only a spec, no implementation? → Decide: implement Rust-side, or delete the spec.
+
+Pace: write up findings as I survey, merge piece by piece. Don't try to do all 100 at once.
+
+### Anomaly noted, not addressed
+
+`ToolRegistry.executeTool` line 638: `parsedParams[key] = value; // Fallback to string`. JSON.parse fails on a complex-type param → stash raw string. This is type-coercion tolerance (under-typed input), not Joel's drifting-fallback pattern. Keep.
+
+---
+
+## 2026-05-29 — Commands triage (slice 1)
+
+First per-command classification slice. Pace: small, focused, document the
+decision per command. No bulk action — each command gets thought.
+
+### Per-command inventory snapshot
+
+(`/tmp/cmd_survey.txt` — 52 top-level command dirs surveyed.)
+
+Top by LOC:
+| Command | LOC | Has spec | Has Rust handler |
+|---|---|---|---|
+| ai | 15,538 | ✓ | ✓ |
+| genome | 10,074 | ✓ | ✓ |
+| development | 9,829 | ✓ | ✓ |
+| interface | 8,602 | ✓ | ✓ |
+| collaboration | 8,453 | ✗ | ✓ |
+| data | 4,736 | ✗ | ✓ |
+| social | 4,436 | ✗ | ✗ |
+| sentinel | 3,512 | ✓ | ✓ |
+| code | 3,197 | ✓ | ✓ |
+| workspace | 3,016 | ✓ | ✓ |
+
+"No spec, no Rust" set (~16 commands totaling ~14 kLOC) is the next bulk
+target — but each gets individual triage rather than mass action.
+
+### Slice 1 commands triaged
+
+#### `ping` (398 LOC, no spec, no Rust handler) — partial action
+
+**Classification:** **#8 — core-shaped TS that should migrate eventually**, but the work is split:
+- Server info collection (process stats, runtime) — **core-shaped**, Rust target.
+- AI status composition (calls `ai/status` command) — **composition example**, the right shape; should be Rust-callable too.
+- Browser info collection — **form-specific**, lives in the web form's implementation; absent for jtag CLI / VR / headless.
+
+**Action taken this slice:** killed an aiStatus all-zeros fallback. The previous catch handler caught any failure of the `ai/status` composition and substituted a synthesized `{ total: 0, healthy: 0, starting: 0, degraded: 0, dead: 0 }` object — i.e., LIED that there were zero AI personas when actually the check itself had failed. Now: if the composition fails, `aiStatus` stays undefined; the caller sees no field and knows the check didn't run.
+
+**Deferred for migration PR:** Rust-implement the server-info + ai-status-composition path. Browser collection stays form-specific.
+
+**Architectural note:** Line 32 — `commandDaemon.commands.get('ai/status')` direct map access (cast hack) instead of `Commands.execute('ai/status', ...)`. Comment retained explaining the same-process-IPC-roundtrip avoidance. When the Rust executor matures, intra-process command composition should be a first-class API, not a map-cast.
+
+#### `help` (461 LOC, no spec, no Rust handler) — classify, defer
+
+**Classification:** **#4/#8 hybrid** — currently filesystem-introspection of the TS command tree on disk. The COMMAND is universal (every form should be able to get help) but the CURRENT implementation reads `src/commands/*/README.md` files from disk, which is intrinsically TS-form (those files only exist in the TS repo layout).
+
+**Right shape long-term:** the command registry (Rust ModuleRegistry today; eventually a unified runtime registry) should expose `describe` introspection. `help` becomes a thin wrapper that queries the registry for command names + their declared descriptions. Then any form gets help symmetrically.
+
+**Action this slice:** none. Classification recorded. Migration target = "registry-introspection-based help" but only meaningful after more commands are Rust-registered.
+
+#### `social` (4,436 LOC commands + ~1,500 LOC support layer) — DROPPED
+
+**Classification:** **deferred → dropped on direct call.** Joel 2026-05-29: "Don't worry about social. Drop it."
+
+**Action taken this slice:** Full cascade delete. Joel's "drop it" applied to the entire concept, not just the command directory — the support layer that exists only to feed those commands also has no purpose without them.
+
+Deleted:
+- `src/commands/social/` (full directory — 14 sub-command surfaces × {browser, server, shared, test} layouts)
+- `src/system/social/` (`SocialCommandHelper`, `SocialMediaProviderRegistry`, `ISocialMediaProvider`, `SocialCredentialEntity`, `SocialMediaTypes`, `MoltbookProvider`)
+- `src/system/rag/sources/SocialMediaRAGSource.ts` (the "social media HUD" RAG injection for personas — Priority 55 entry in ChatRAGBuilder)
+
+Patched out of:
+- `src/system/rag/builders/ChatRAGBuilder.ts` — removed import + `new SocialMediaRAGSource()` from the source chain
+- `src/system/rag/sources/index.ts` — removed export
+- `src/daemons/data-daemon/server/EntityRegistry.ts` — removed `SocialCredentialEntity` import, instantiation, and `registerEntity` call
+- `tools/generator/generate-collection-constants.ts` — removed `system/social/shared/*Entity.ts` from the entity-discovery globs
+
+Regenerated:
+- `src/server/generated.ts` + `src/browser/generated.ts` via `npx tsx tools/generator/generate-structure.ts` — went from 351 to 343 commands
+
+**Net delete:** ≈ 5,800+ LOC of TS surface across 100+ files. TS still compiles clean (the 6 pre-existing `Cannot find module '../config'` errors remain unchanged).
+
+**Note on the broader principle:** the social subsystem is also a worked example of why TS-locked commands are dangerous — it consumed RAG priority on every persona's context, even though no production form was actively exercising it. The cost was carried by every persona, every message, in TS time. With it gone, the persona context becomes cleaner AND the kloc drops.
+
+---
+
+## 2026-05-29 — Commands triage (slice 2)
+
+Four small no-spec-no-Rust commands triaged. No code changes — the classifications are the value; future-me and peer reading this know what each is and what its migration shape is.
+
+#### `indicator` (153 LOC) — KEEP
+
+**Classification:** #4 (form-specific implementation of a universal command).
+
+Server emits a console.log line with a type icon, then delegates to the browser via `remoteExecute(params)`. Browser presumably creates a visual DOM notification (toast). Per-form impl is correct: CLI/jtag form prints to terminal, web form renders a UI element, VR/AR form would render a 3D-world notification, headless form may no-op or log.
+
+**Note:** when a persona uses `indicator` as a tool call, the indicator surfaces in whatever form the user is currently inhabiting (web/VR/AR). That's the Tron-citizen materializing in the user's room.
+
+#### `positron/cursor` (192 LOC) — KEEP, future reorg suggested
+
+**Classification:** #4 (form-specific implementation of a universal command).
+
+"Enables AIs to point, highlight, and draw attention to elements in the UI. The cursor is the AI's 'hand' - its spatial presence in the interface." Server delegates to browser; browser draws DOM overlay (circle/rectangle/arrow/underline) at coordinates or selector.
+
+**Reorg note** (per organization-purity doctrine): `positron/` has only one child (`cursor`). The cursor concept fits under `interface/` (which already has click, screenshot, scroll, type, navigate, etc. — all UI presence commands). Future move: `positron/cursor/` → `interface/cursor/`. Not in this slice — would cascade through generated.ts, command constants, DocumentationSource references. Tracked here for when it's the right opportunity.
+
+#### `list` (492 LOC) — DEFER MIGRATE
+
+**Classification:** #4/#8 hybrid.
+
+Currently reads `tools/scripts/generate-command-schemas.ts` output from disk (TS-form filesystem introspection). The CONCEPT is universal (any caller asks "what commands exist?"), but the IMPLEMENTATION reads files specific to the TS form's layout.
+
+**Right shape long-term:** the Rust ModuleRegistry exposes introspection. `list` becomes a thin wrapper that queries the registry. Then any form (web UI, jtag CLI, VR persona, headless grid node) gets the same enumeration via the same path.
+
+**Migration target:** post-grid-extension of ModuleRegistry. Defer until enough commands are Rust-registered that registry-introspection is meaningful.
+
+#### `recipe` (515 LOC) — DEFER MIGRATE
+
+**Classification:** #8 (core-shaped TS that should migrate), gated on room-is-airc embed.
+
+`recipe/run` loads a recipe by uniqueId, resolves template, validates model availability via RecipeAssembler, dispatches to `sentinel/run` with the resolved template. The TS body is mostly orchestration — composing other commands.
+
+Joel 2026-05-29: "Recipes create rooms — `airc.join('<recipe-id>')` materializes a room on demand, room doctrine system at `Airc::room_doctrine` carries the per-recipe behavior."
+
+**Right shape:** recipe/run becomes a Rust command that:
+1. `airc.join(recipe.uniqueId)` — materializes the airc room for this recipe
+2. Loads recipe definition (likely from `#settings` per peer's 1224aac2 card)
+3. Attaches the recipe's roleId-mapped personas as airc peers in the room
+4. Dispatches to sentinel orchestration (also moving to Rust)
+
+**Migration target:** gated on (a) airc#1075 ConsumerAdapter merge unblocking continuum-core's airc::embed, (b) airc room creation API stabilized, (c) #settings room (1224aac2) for recipe definition storage. Once those three land, the whole recipe-run orchestration moves to Rust in one slice.
+
+### Open questions for follow-up slices
+
+- The "no spec, no Rust" set totals ~14 kLOC. Going slice-by-slice (3–5 commands at a time) is the survivable pace.
+- The "has spec, no Rust" set (e.g., `model`, `state`, `dev`, `claude`, `logging`) means the generator produced TS-side scaffolding but the Rust impl was never written. Each is a candidate for Rust implementation OR for spec deletion (if the command shouldn't exist).
+- Several big "has Rust" commands (`ai`, `genome`, `development`) probably have substantial TS bodies *on top of* the Rust path. Worth checking if those TS bodies duplicate Rust logic.
+
+---
+
+## 2026-05-29 — Chat-message-flow migration scope (gated on airc e51ab14e)
+
+Airc PR #1084 (Phase 1.C — chat substrate throughput 281→498 msg/s) merged. I committed to peer that I'd start the continuum-side dual-write shim deletion against that release boundary. **Correction after surveying: the shim deletion is the front of a much bigger migration**, gated on **airc card e51ab14e (machine-singular daemon)**, not on Phase 1.C. Documenting the full scope now so the slice is peer-reviewable and ready to execute when e51ab14e lands.
+
+### Today's dual-write architecture
+
+```
+ChatSendServerCommand (commands/collaboration/chat/send/server/)
+  └→ AircChatDualWriteService (system/airc-chat/server/)
+      ├→ AircChatPublisher → publishes to airc room
+      └→ AircToORMMirrorWriter → writes ChatMessageEntity to local ORM
+```
+
+The TS shim (`system/airc-chat/` — 1069 LOC: publisher, dual-write service, mirror writer, mapper, types, envelope builder + 4 test files) is just the write side. The mirror entity is then READ by many continuum-side consumers from the local ORM, which means deleting only the writer leaves readers reading silently-stale data — exactly the silent-fallback pattern the doctrine forbids.
+
+### ChatMessageEntity readers (the actual migration surface)
+
+| Reader | Purpose | Migration target |
+|---|---|---|
+| `PersonaUser.catchUpOnRecentMessages` (~line 1232) | Startup catch-up on missed messages per room | Airc room history query at startup; result shape matches today's ORM query |
+| `PersonaUser.handleChatMessage` (downstream of catch-up) | Process backlog message | Same handler, fed from airc subscription instead of ORM read |
+| `TrainingDaemonServer` (line ~233) | Capture chat for training data | Airc room subscription buffered into training pipeline; or read from airc history when training run starts |
+| `ToolRegistry` chat-message handling | Tool call embedding/extraction from chat | Read from airc room (likely already form-specific since tools see chat from inside the room) |
+| `RoomActivityBatch` (system/user/server/attention/) | Batch room activity for attention/presence | Airc presence + room event subscription, not ORM query |
+| Generated bindings (`RecentMessage`, `ToolOutcome`, `MediaItemLite`) | ts-rs-emitted types | Stay typed; airc envelope content is structurally compatible. Regenerate once Rust-side airc message types stabilize |
+
+### Why this is gated on e51ab14e
+
+Without machine-singular daemon, multiple personas on one box are different airc peers in different process scopes. They can each publish to a shared room but **don't see each other's writes live** — only at point-in-time queries against the coordinator store. So:
+
+- A persona enrolled in `general` writes its response to airc
+- The other 14 personas don't see that response in real time
+- They only see it when something triggers a point-in-time history query
+- Result: the 15-persona scenario looks like turn-based correspondence, not a live room
+
+With e51ab14e (one daemon per machine-account), all personas on Joel's box share one airc daemon bus, live delivery works across processes, the scenario actually works.
+
+### Migration sequencing (when e51ab14e lands)
+
+1. **Subscribe** — wire each ChatMessageEntity reader to an airc room subscription instead of ORM polling. Additive: readers see both the airc subscription AND the dual-write ORM data; behaviors should be identical.
+2. **Verify** — run the 15-persona general-room scenario, confirm subscription-based reads match dual-write reads.
+3. **Stop dual-writing** — `ChatSendServerCommand` calls `AircChatPublisher` directly, no `AircToORMMirrorWriter`. ORM mirror stops being written; readers (now subscription-based) don't care.
+4. **Delete the shim** — `system/airc-chat/` (1069 LOC TS).
+5. **Verify CHAT_MESSAGES collection is unwritten** — if nothing writes to it, the collection is dead. Delete the entity + remove from EntityRegistry.
+6. **Bench** — measure continuum-side throughput against substrate's Phase 1.C 498 msg/s baseline. If continuum-side flow doesn't keep up, that's a fresh bottleneck to find.
+
+### NOT the shim
+
+- The Rust `airc_admission.rs` in `continuum-core/src/persona/` is **NOT** the dual-write shim. It's the memory admission path that converts a signed airc envelope into an AdmissionCandidate for persona memory. Stays.
+- WebRTC SDP / MediaSignaling handling — likely already on the airc side; verify when wiring the live multi-persona test.
+- Theme / room presentation — independent of chat-message migration; web form's concern, no substrate change needed.
+
+### Pre-work I can do without blockers
+
+- Each ChatMessageEntity reader's subscription-shape sketch (what `airc_subscribe` call replaces what `ORM.query`).
+- Bench harness for the 15-persona scenario (compile-time even if can't run yet).
+- Cleanup of any silent-fallback patterns in the readers (`catch { return [] }` etc.) — independent doctrine work.
+
+Surfaces as separate slices as I get to them.

+# Chat-to-AIRC Migration Inventory
+
+Generated for continuum#1253 on 2026-05-16.
+
+This is the current Continuum-side inventory for moving chat from the
+ORM-backed `chat_messages` collection to AIRC transcript APIs. It is a proof
+artifact, not a design sketch: migration PRs must regenerate it and reconcile
+the diff before changing storage behavior.
+
+## Regeneration Commands
+
+```bash
+rg -n "COLLECTIONS\.CHAT_MESSAGES|chat_messages" \
+  src/commands src/widgets src/system \
+  -g '!**/__tests__/**' -g '!**/*.test.*' -g '!**/*.spec.*'
+
+rg -n "Commands\.execute\\(['\"]collaboration/chat/|command:\s*['\"]collaboration/chat/|client\.commands\[['\"]collaboration/chat/" \
+  src/widgets src/system src/commands
+
+rg -n "DATA_EVENTS\.CHAT_MESSAGES|data:chat_messages:" src/
+```
+
+## Storage Entity And ORM Hot Path
+
+| Area | Current path | Migration concern |
+|---|---|---|
+| Entity schema | `src/system/data/entities/ChatMessageEntity.ts` | `chat_messages` still defines room/timestamp indexes, archive policy, JSON media metadata, receipts, reactions, threading, and metadata semantics. AIRC must preserve equivalent transcript/projection fields before Stage 3 removal. |
+| Write command | `src/commands/collaboration/chat/send/server/ChatSendServerCommand.ts` | Builds `ChatMessageEntity`, externalizes media, calls `DataCreate` on `ChatMessageEntity.collection`, then invokes `AircChatDualWriteService` for the Stage 1 AIRC handoff. |
+| AIRC chat envelope | `src/system/airc-chat/shared/AircChatEnvelope.ts` | Maps stored ORM chat messages into generated `AircRealtimeEnvelope` / `chat_transcript` payloads. Carries ORM id as `traceId`; media is refs only. |
+| AIRC chat publisher seam | `src/system/airc-chat/server/AircChatPublisher.ts` | Publishes the generated envelope through AIRC's structured `publish` surface, sends JSON on stdin, sets filterable headers, and accepts only the JSON receipt. |
+| Export command | `src/commands/collaboration/chat/export/server/ChatExportServerCommand.ts` | Reads via `DataList` using `ChatMessageEntity.collection`, applies filtering, then emits markdown. Stage 2 must prove export parity from AIRC or mirror. |
+| Poll command | `src/commands/collaboration/chat/poll/server/ChatPollServerCommand.ts` | Reads `chat_messages` through `ORM.query`, including `afterMessageId` timestamp lookup. This is a direct ORM dependency and a latency-sensitive agent path. |
+| Analyze command | `src/commands/collaboration/chat/analyze/server/ChatAnalyzeServerCommand.ts` | Aggregates over `ChatMessageEntity`. Keep as projection consumer until AIRC-backed aggregation is proven. |
+| Data read access control | `src/commands/data/read/server/DataReadServerCommand.ts` | Has a `COLLECTIONS.CHAT_MESSAGES` special case. Equivalent AIRC access policy is a Stage 2 gate. |
+| Field config/cache | `src/system/data/config/EntityFieldConfig.ts`, `src/system/state/EntityCacheService.ts` | Chat has collection-specific field and cache pressure behavior. Removing ORM chat must replace or delete these intentionally. |
+
+## Producers
+
+| Area | Current path | Migration concern |
+|---|---|---|
+| Chat command callers | `src/widgets/chat/*`, `src/system/sentinel/SentinelChatBridge.ts`, `src/system/sentinel/pipelines/*` | Many paths call `collaboration/chat/send`; keep command compatibility as a thin shim while swapping the backing store. |
+| Persona replies | `src/system/user/server/PersonaUser.ts` | Persona writes to `COLLECTIONS.CHAT_MESSAGES` around reply/system-message paths. These writes must move to AIRC transcript append or a single adapter. |
+| Tool results | `src/system/user/server/modules/PersonaTaskExecutor.ts` | Stores tool result messages in `COLLECTIONS.CHAT_MESSAGES`; must become an explicit transcript/projection event, not implicit ORM rows. |
+| Voice bridge | `src/system/voice/server/VoiceWebSocketHandler.ts` | Bridges voice and chat events. AIRC should carry presence/control/events, while WebRTC/LiveKit keeps media. |
+| Sentinel pipelines | `src/system/sentinel/pipelines/*` | Large fanout of `command: 'collaboration/chat/send'`; do not migrate piecemeal without preserving the command contract. |
+
+## Consumers
+
+| Area | Current path | Migration concern |
+|---|---|---|
+| UI loaders | `src/widgets/shared/DataLoaders.ts`, chat widget paths | The browser must render live updates from AIRC or a projection with no stale poll dependency. |
+| Persona inbox | `src/system/user/shared/BaseUser.ts`, `src/system/user/server/PersonaUser.ts`, `src/system/user/server/modules/PersonaMessageGate.ts` | Subscribes to `data:chat_messages:created`. Stage 2 requires AIRC subscription/replay to preserve persona response behavior. |
+| Training and memory | `src/daemons/training-daemon/server/TrainingDaemonServer.ts`, `src/system/user/server/modules/PersonaTrainingSignalExtractor.ts`, `src/system/genome/fine-tuning/server/TrainingDatasetBuilder.ts` | Training examples and memory candidates consume chat history. Cursor replay and deterministic ordering are mandatory gates. |
+| AI context/reporting | `src/commands/ai/thoughtstream/server/ThoughtStreamServerCommand.ts`, `src/commands/ai/report/server/AIReportServerCommand.ts`, `src/commands/ai/context/*`, `src/commands/ai/should-respond-fast/server/*` | These consumers need either AIRC page APIs or bounded SQLite projections. Do not leave them on direct `chat_messages` strings. |
+| Voice/live session | `src/system/voice/server/VoiceWebSocketHandler.ts` | Presence and chat events should route through AIRC events; media remains side-channel WebRTC/LiveKit. |
+| Event constants | `src/system/core/shared/EventConstants.ts`, `src/system/events/shared/EventSystemConstants.ts` | `DATA_EVENTS.CHAT_MESSAGES` is a compatibility boundary. Stage 3 removal requires no runtime subscriber still depends on it. |
+
+## AIRC Interface Gates
+
+Continuum should not depend on AIRC internals or SQL tables. The expected
+contract is a typed adapter over AIRC's Rust transcript/event store:
+
+| Capability | Required behavior |
+|---|---|
+| Append | Send chat/event/presence entries with idempotent IDs, author metadata, room/activity pointer, and attachment manifest refs. |
+| Page | Return recent and cursor-based pages with deterministic ordering, stable IDs, and self-message filtering. AIRC PR #638 provides the first `airc logs --json` CLI page shape. |
+| Replay | Resume from a cursor without tailing raw logs or scanning unbounded history. |
+| Receipts | Carry delivered/read/processed receipts without coupling to `ChatMessageEntity` fields. |
+| Attachments | Preserve media blob hashes, URLs, MIME metadata, and descriptions without reintroducing inline base64 into database columns or events. |
+| Presence/control | Carry `is typing`, `is thinking`, speaking, in-call, subscription, and WebRTC/LiveKit coordination events. |
+| Health/capacity | Expose queue depth, storage pressure, replay lag, subprocess count, and disk write metrics for performance gates. |
+
+## Stage-1 Blockers
+
+- The AIRC transcript API must be typed and Rust-owned. Python/shell output can remain compatibility glue only.
+- Continuum adapters must use command/entity abstractions; no raw SQL migration path is acceptable.
+- The dual-write failure model must be explicit: no silent ORM-only or AIRC-only success.
+- Media manifests must be proven with real image/audio metadata and no inline base64 persistence.
+- Fresh install must work with no local Postgres and no `DATABASE_URL`.
+
+## Performance Evidence Required
+
+Every migration PR must report before/after measurements for:
+
+- chat send latency
+- page/export latency
+- persona reply roundtrip latency
+- event/replay lag
+- CPU during idle and active chat
+- memory and subprocess count
+- disk writes and SQLite/AIRC store growth
+
+The target is lower setup friction and lower runtime load, not a lateral move
+from one storage path to another.

+# CI Automation Plan — Build For The Multi-Agent Workflow
+
+**Status**: Plan, 2026-05-01. Phase A actively shipping.
+**Origin**: live #974 meta-blocker discovery during the M5-QA + dev-tab + M1-Carl-validator parallel session of 2026-05-01.
+**Top-level GitHub issue**: see [issue link to be added once filed].
+
+## Why this exists
+
+We're building Continuum + airc as a coordinated multi-agent project. Today's session demonstrated the workflow: M5-dev + M5-QA + M1-Carl-validator + airc mesh coordination, with continuous PRs landing through canary. To sustain that pattern, the CI must be:
+
+1. **Repeatable.** Any future hardware contributor (Toby, anyone) can plug in without bespoke setup.
+2. **Self-aware.** The right gates fire for the right kind of change. Nobody manually triggers workflows.
+3. **Image-producing automatically.** When a PR touches Docker-relevant code, CI builds the images — no "did anyone remember to push?" question.
+4. **Mesh-observable.** The build farm's state is visible on airc, just like every other peer's state.
+
+Today's blocker (#974): the existing `docker-images.yml` workflow only fires on PRs targeting `main` AND only when `core/**` or `docker/**` paths change. PRs targeting `canary` (the working integration branch) silently never produce the required-status-checks `verify-architectures` and `verify-after-rebuild` that the canary ruleset gates merges on. **Result**: every TS-only or doc-only PR is permanently un-mergeable to canary.
+

+
+## Phases
+
+### Phase A — Self-aware required check (THIS PR — fix/974-conditional-docker-verify)
+
+**What.** Modify `.github/workflows/docker-images.yml`:
+- `pull_request.branches: [main, canary]` — fire on PRs to either branch
+- Remove `pull_request.paths` — workflow ALWAYS fires
+- Add a `detect` step using `dorny/paths-filter@v3` to compute `docker_relevant` boolean
+- When `docker_relevant == false`: emit `::notice` + auto-pass the job (required check satisfied without touching ghcr)
+- When `docker_relevant == true`: run the existing verification flow unchanged
+- Apply the same pattern to `verify-after-rebuild`
+- Job-output fallback chain (`steps.skip-pass.outputs.X || steps.gate.outputs.X`) so downstream jobs read sane values regardless of which path ran
+
+**Why.** Unblocks the 4 PRs targeting canary (continuum#976/#977/#978/#979 + the M5-QA fixes stacked on top). Doesn't require any hardware changes. Doesn't change the existing image-verification semantics — only the gating semantics for non-relevant PRs.
+
+**Done when**: a TS-only PR targeting canary fires the workflow + sees `verify-architectures` PASS + sees `verify-after-rebuild` PASS + becomes mergeable. Then this Phase A PR itself becomes mergeable to main (via the `[main]` filter, which still fires it for main-targeting PRs since `docker-compose.yml` is in the path) → cherry-pick to canary.
+
+**Status as of 2026-05-01 PM**: PR opening this session.
+
+### Phase B — Self-hosted runner registration
+
+**What.** Register continuum dev hardware as GitHub Actions self-hosted runners.
+
+- **BigMama** (Linux + Nvidia 5090 + amd64): runner labels `[self-hosted, linux, amd64, cuda]`.
+- **Mac M5** (macOS + Apple Silicon + Metal): runner labels `[self-hosted, macos, arm64, metal]`.
+- Document the registration steps in `docs/infrastructure/SELF-HOSTED-RUNNERS.md` (paired with this doc) — exact `gh-runner` install + `gh repo set-default` + `./config.sh` invocation. Should be a 5-line copy-paste any future contributor (Toby, Carl, anyone) can run on their hardware to add it to the build farm.
+
+**Why.** The existing scripts (`scripts/push-current-arch.sh`, `scripts/push-image.sh`) already do the right thing on dev hardware — they build per-arch + push to ghcr. To eliminate the "who's pushing?" question, the same hardware needs to be reachable as a CI runner so the workflow can dispatch builds automatically.
+
+**Done when**: GHA dashboard shows BigMama + Mac M5 as online runners with the label sets above. A no-op workflow targeting `runs-on: [self-hosted, linux, amd64]` succeeds on BigMama; same for Mac arm64.
+
+### Phase C — Automated image build on docker_relevant changes
+
+**What.** When `detect.outputs.docker_relevant == true`, dispatch parallel build jobs:
+
+- `build-amd64` runs on BigMama, invokes `bash scripts/push-current-arch.sh`
+- `build-arm64` runs on Mac M5, invokes `bash scripts/push-current-arch.sh`
+- Both push images to ghcr at `:pr-<N>` tag for the PR
+- `verify-architectures` job (existing, real verification path) runs after both builds + finds the images + passes
+
+**Why.** Eliminates manual `push-current-arch.sh` invocation. PRs that touch Rust/Docker just get their images automatically. The verify gate becomes meaningful (it's verifying images that the PR's CI itself produced).
+
+**Done when**: a PR that touches `core/continuum-core/Cargo.toml` opens; `build-amd64` runs on BigMama + pushes the amd64 image; `build-arm64` runs on Mac + pushes the arm64 image; `verify-architectures` finds both + passes; PR mergeable.
+
+### Phase D — Multi-arch manifest stitching
+
+**What.** After both arch builds push, a tiny `stitch-manifest` job composes the multi-arch manifest at the `:pr-<N>` tag using `docker buildx imagetools create`. `verify-architectures` then sees both arches in one tag.
+
+**Why.** The verify step expects a single tag with both arches. Without stitching, it would only see one arch at a time + fail the cross-arch check.
+
+**Done when**: `docker buildx imagetools inspect ghcr.io/cambriantech/continuum-core:pr-<N>` shows both `linux/amd64` and `linux/arm64` (and `darwin/arm64` if Mac builds in the docker-darwin mode — TBD, depends on what `push-current-arch.sh` does on Mac).
+
+### Phase E — Caching + skip-if-exists
+
+**What.** Before invoking the heavy build, hit ghcr with a HEAD request to check if an image already exists at the SHA. If so, skip the build entirely.
+
+```yaml
+- name: Skip build if image already at SHA
+  id: cache_check
+  run: |
+    if curl -sI "https://ghcr.io/.../continuum-core:${SHORT_SHA}" -H "Authorization: Bearer ${TOKEN}" | head -1 | grep -q "200"; then
+      echo "skip=true" >> "$GITHUB_OUTPUT"
+    fi
+- name: Build
+  if: steps.cache_check.outputs.skip != 'true'
+  run: bash scripts/push-current-arch.sh
+```
+
+Also: cache `Cargo.lock` content-hash → image-SHA mapping in a small registry-side metadata file so even repeat-rebuilds across PRs reuse images.
+
+**Why.** Cuts CI burn by ~80% for repeat-rebuilds (especially during stack-of-PRs cycles where the same Rust core is referenced across multiple PRs).
+
+**Done when**: a no-op PR that doesn't change Cargo.lock OR Dockerfile reuses the previous image; build job time < 30s for the cache-hit path.
+
+### Phase F — airc-side observability + capability publication
+
+**What.** Each self-hosted runner publishes its online state + capability on the `#ai-capability` airc channel (per AGENT-BACKBONE §4.3). The continuum orchestrator subscribes to this channel + can see which runners are online.
+
+Optional next layer: when a PR opens that requires Docker builds AND no suitable runner is online, the orchestrator (or a meta-coordinator agent) DM's the appropriate hardware owner via airc to ask them to wake the runner.
+
+**Why.** Folds the build farm into the same mesh-observability layer the rest of the system uses. Same airc channel humans use to coordinate; runners become first-class peers.
+
+**Done when**: `airc capabilities` lists each online runner with its arch/GPU/role; the orchestrator can be queried for "is BigMama runner up?"; PR comment auto-posts "build-amd64 queued, BigMama offline — will start when it returns" if relevant.
+
+## Risks + mitigations
+
+- **Self-hosted runners need to stay online.** Mitigation: airc-side observability (Phase F) surfaces "runner offline" + the existing `airc daemon install` keeps runners up across machine sleep/wake (mirror of the airc#382 work).
+- **Self-hosted runners get attack surface.** Mitigation: GHA's "require approval for first-time contributors" + the runners only run scripts already in the repo + airc-mesh contributors are gh-org members.
+- **ghcr storage grows with every PR.** Mitigation: separate prune workflow that drops `:pr-<N>` tags after merge.
+- **Phase A's auto-skip could mask real Docker bugs in Rust-only PRs.** Mitigation: the path filter is conservative — `core/**/Cargo.{toml,lock}` triggers the full path even for "small" Rust changes. False positives (running real verification when a Rust change actually had no Docker impact) are cheap; false negatives (skipping when a real check was needed) are tracked + the path-filter list is tightened over time as we observe.
+
+## Action item: top-level GitHub issue
+
+This doc is referenced from a top-level continuum GitHub issue that tracks each phase as a sub-task with its own PR + status. As phases land, sub-tasks are checked off; the parent issue stays open until Phase F lands. That way the full plan is visible to anyone landing on the issue tracker, not buried in this doc.
+
+## Today's mesh-coordination context
+
+This plan was authored as part of Joel's "coordinated parallelism" framing for today's session:
+
+- **M5 dev tab** (continuum-b741): owns F4 (carl-killer IPC pool recovery) + #75 (persona output quality) — TS-side fixes
+- **M5 QA tab** (continuum-b741, this doc's author): owns Phase A + this doc + the issue
+- **M1 Carl-validator tab**: owns post-Phase-A install validation + reporting findings via airc
+- **Joel**: owns Phase B (runner registration on the hardware boxes) + the canary ruleset call
+
+This doc + the top-level issue formalize that division so the mesh has a shared reference for who's doing what + what depends on what.

+# Path Ownership
+
+Continuum has multiple state roots because some data belongs to the repo, some to the current checkout, and some to the local user or machine. Code must make that ownership explicit. A path that depends on one developer's username, home directory, package manager, host layout, or SSH account is a bug.
+
+## Owned Roots
+
+| Root | Owner | Purpose | Commit Policy |
+| --- | --- | --- | --- |
+| `.airc/` | Repository | Project collaboration policy, onboarding, and queue documentation | Tracked only when the file is intentional project documentation |
+| `src/.airc/` | Local AIRC runtime | Scoped AIRC state created by commands, lanes, monitors, and tool integrations | Ignored; never commit runtime state or secrets |
+| `src/.continuum/` | Local Continuum runtime | App, test, generated, socket, session, and scratch state for this checkout | Ignored unless a generated artifact is deliberately promoted through the generator pipeline |
+| `$HOME/.continuum/` | Local user | User config, secrets, model caches, machine-local logs, large artifacts, and long-lived local state | Never commit; paths must be configurable and must not assume a username |
+| `$AIRC_HOME`, `~/.airc-*`, `.airc-worktrees/` | Local AIRC install/runtime | AIRC install, mesh state, and isolated worktrees | Never commit from Continuum |
+
+## Rules
+
+- Do not hardcode `/Users/joelteply`, `/home/joel`, `joel@`, Homebrew paths, or machine-specific mount points in executable code.
+- Use `SystemPaths` or a small domain-specific path helper for Continuum-owned state. Add a helper before adding another one-off `path.join(process.cwd(), '.continuum', ...)`.
+- Use `os.homedir()`, `process.env.HOME`, `PathBuf`, or an explicit environment/config value for user-owned state.
+- Use command lookup through `PATH` for tools such as `espeak-ng`; allow an override such as `ESPEAK_NG_BIN` when local installs need it.
+- Remote SSH commands must use `CONTINUUM_SSH_USER`, then safe local defaults such as `USER` or `LOGNAME`. They must not assume a developer account name.
+- Scripts that need large local artifacts should accept a path override and default under `$HOME/.continuum`, not a personal home path.
+- Generated TypeScript/Rust boundary files belong in the established generated output tree and should come from `ts-rs` or the generator, not handwritten parallel types.
+- Tests should write under ignored checkout-local temp/state roots or OS temp directories. Fixture emails and display names are fine; machine paths and real usernames are not.
+
+## Current Overrides
+
+| Variable | Meaning |
+| --- | --- |
+| `CONTINUUM_HOME` | Preferred future override for user-level Continuum state |
+| `CONTINUUM_ROOT` | Preferred future override for checkout-level Continuum state |
+| `CONTINUUM_SSH_USER` | SSH account for grid and remote model commands |
+| `CONTINUUM_COMPACTION_MODEL` | Local model path for compaction profiling |
+| `ESPEAK_NG_BIN` | `espeak-ng` executable path when it is not on `PATH` |
+
+## Review Checklist
+
+- New code has no personal absolute path, host-specific path, or hardcoded SSH user.
+- The root of every new path is visibly repo-owned, checkout-local, user-local, or OS temp.
+- The path can work on macOS, Linux, and Windows/WSL unless the feature is explicitly platform-gated.
+- Runtime output is ignored by Git.
+- If the same path construction appears twice, move it into `SystemPaths` or the relevant Rust path module before merging.

+# Rust Comms Transport Traits
+
+**Status:** design for #1175. Rust is the source of truth; TypeScript consumes
+generated edge types through `ts-rs` and should not own transport policy.
+
+## Problem
+
+Continuum has several communication paths with the same hidden shape:
+
+- build an envelope around a command, event, transcript message, media frame, or
+  artifact pointer
+- track identity, correlation, ordering, and replay safety
+- enforce some budget: bytes, latency, queue depth, CPU, memory, GPU residency,
+  retry count, or retention
+- decide who owns the buffer and whether the next hop may borrow, clone, move,
+  spill, or drop it
+
+Today those concerns are repeated across IPC, grid transport, AIRC projection,
+live media, and planned remote execution. The repetition is the smell. The fix
+is a small Rust-owned trait layer that every transport implements, with a
+shared envelope, shared resource accounting, and explicit ownership semantics.
+
+## Existing Surfaces
+
+| Surface | Current role | Payload class | Hot-path risk |
+|---|---|---|---|
+| `ipc/*` and command runtime | Browser/Node to Rust command execution | JSON command/request/response | unbounded calls, timeout drift, duplicate envelope logic |
+| `modules/grid/*` | node-to-node routing over Tailscale/Reticulum-style links | `GridFrame` JSON | transport-specific frames hide common budgets |
+| `airc/*` and `modules/airc.rs` | AIRC queue/transcript projection into Continuum | issue/card/transcript JSON | process spawn cost, unclear retention boundaries |
+| `live/transport/*` | LiveKit/WebRTC bridge and call server | audio/video tracks, session events | accidental CPU copies, codec-specific duplication |
+| `live/avatar/*` and Bevy-facing paths | avatar render output and animation state | GPU textures, frame handles, pose/state events | rasterizing to CPU buffers instead of transferring handles |
+| `modules/sentinel/*` | agent workflow execution | steps, logs, tool calls, artifacts | log/event transport policy spread across steps |
+| data/entity modules | durable projections and CRUD | typed entities, generated TS | schema drift if TS recreates Rust contracts |
+
+These should stay separate at the product boundary. They should not stay
+separate for envelope shape, budget enforcement, observability, or buffer
+ownership.
+
+## Non-Negotiables
+
+- Rust defines transport contracts, policy, and resource accounting.
+- TypeScript receives generated types or thin adapters; it does not invent
+  parallel envelopes.
+- Heavy payloads do not cross AIRC. AIRC carries messages, manifests, hashes,
+  room ids, job ids, and proof pointers.
+- Media and render paths prefer handle transfer over CPU bytes. CPU copy is a
+  named fallback with a metric and a test gate.
+- Every transport has backpressure. Dropping, retrying, spilling, or refusing is
+  explicit.
+- Every payload declares a resource budget before it is sent.
+- Every envelope has correlation, causality, provenance, and replay fields.
+
+## Core Types
+
+The first code slice should add these types under a neutral Rust module such as
+`core/continuum-core/src/comms/`.
+
+```rust
+pub struct TransportEnvelope<T> {
+    pub id: MessageId,
+    pub correlation_id: CorrelationId,
+    pub causality: Causality,
+    pub source: EndpointId,
+    pub target: EndpointId,
+    pub class: PayloadClass,
+    pub budget: ResourceBudget,
+    pub integrity: IntegrityHint,
+    pub payload: T,
+}
+
+pub enum PayloadClass {
+    Control,
+    Command,
+    Event,
+    Transcript,
+    ArtifactManifest,
+    AudioFrame,
+    VideoFrame,
+    GpuFrameHandle,
+}
+
+pub struct ResourceBudget {
+    pub max_bytes: u64,
+    pub deadline_ms: u64,
+    pub max_queue_depth: u32,
+    pub cpu_copy_budget: CopyBudget,
+    pub memory_budget: MemoryBudget,
+    pub gpu_budget: GpuBudget,
+    pub retry_budget: RetryBudget,
+    pub retention: RetentionPolicy,
+}
+
+pub enum BufferLease<T> {
+    Borrowed(T),
+    Owned(T),
+    Shared(Arc<T>),
+    External(ExternalBufferRef),
+    Gpu(GpuBufferRef),
+}
+```
+
+The important part is not the exact names. The important part is that ownership
+and accounting are typed, reviewed, and impossible to forget at each callsite.
+
+## Trait Surface
+
+```rust
+#[async_trait]
+pub trait ContinuumTransport: Send + Sync {
+    type Payload: Send + Sync + 'static;
+    type Error: std::error::Error + Send + Sync + 'static;
+
+    fn name(&self) -> &'static str;
+    fn capabilities(&self) -> TransportCapabilities;
+    fn local_endpoint(&self) -> EndpointId;
+    fn metrics(&self) -> TransportMetricsSnapshot;
+
+    async fn send(
+        &self,
+        envelope: TransportEnvelope<BufferLease<Self::Payload>>,
+    ) -> Result<DeliveryReceipt, Self::Error>;
+
+    async fn recv(&self) -> Result<TransportEnvelope<BufferLease<Self::Payload>>, Self::Error>;
+    async fn flush(&self, fence: FlushFence) -> Result<(), Self::Error>;
+    async fn shutdown(&self) -> Result<(), Self::Error>;
+}
+
+pub trait ResourceAccounted {
+    fn declared_cost(&self) -> ResourceCost;
+    fn measured_cost(&self) -> ResourceCost;
+    fn assert_within_budget(&self, budget: &ResourceBudget) -> Result<(), BudgetViolation>;
+}
+
+pub trait ZeroCopyEligible {
+    fn copy_count(&self) -> u32;
+    fn can_share_across(&self, boundary: TransportBoundary) -> bool;
+    fn external_ref(&self) -> Option<ExternalBufferRef>;
+    fn gpu_ref(&self) -> Option<GpuBufferRef>;
+}
+```
+
+This is intentionally above `GridTransport`. `GridTransport` remains the
+node-link implementation detail. `ContinuumTransport` is the common contract for
+IPC, AIRC projection, grid routing, media, and artifact/control messaging.
+
+## Transport Adapters
+
+| Adapter | First implementation target | Notes |
+|---|---|---|
+| `IpcCommandTransport` | Rust IPC command boundary | wraps command/response envelopes and makes timeout/backpressure visible |
+| `AircQueueTransport` | `airc/queue-scan` and transcript projection | process cost and retention are measured, AIRC stays lightweight |
+| `GridNodeTransport` | existing `GridTransport` | maps `GridFrame` into common envelopes without deleting current tests |
+| `LiveMediaTransport` | live audio/session events | track-level budgets, no duplicate audio/video policy |
+| `GpuFrameTransport` | Bevy/avatar to LiveKit path | handle-first path; CPU raster bytes require fallback metric |
+| `ArtifactManifestTransport` | Forge/proof/data pointers | moves hashes and manifests, not bulky artifacts |
+
+Each adapter can start as a thin wrapper around existing code. The win is that
+the wrappers expose common metrics and budget failures immediately.
+
+## Budget Gates
+
+Every merged adapter should add tests or VDD probes for the relevant budget:
+
+- command/control: request timeout propagation, cancellation, queue depth,
+  retry count, and response correlation
+- AIRC: CLI process latency, bytes emitted, retained transcript rows, and
+  explicit skip for heavy payload classes
+- grid: frame bytes, connect latency, encryption capability, replay rejection
+- audio: frame duration, sample rate, queue depth, drop count, and copy count
+- video/render: GPU residency, frame handle transfer, CPU copy count, encode
+  latency, and frame pacing
+- artifacts: manifest byte size, hash integrity, storage pointer validity, and
+  retention policy
+
+A PR that moves a hot path must prove one of these numbers did not regress.
+When the number is not yet measurable, the PR adds the probe before changing
+the path.
+
+## Migration Plan
+
+1. Add `comms` core types and unit tests for serialization, budget validation,
+   and copy-count accounting. Export only TS-safe types with `ts-rs`.
+2. Wrap AIRC queue scan and IPC command calls first because they are lower-risk
+   JSON/control paths.
+3. Wrap `GridTransport` without removing the current trait. This gives remote
+   execution shared accounting while preserving Tailscale/Reticulum tests.
+4. Wrap live audio session events and add copy-count metrics before touching
+   video.
+5. Add the GPU frame handle path separately. The acceptance test must fail if a
+   Bevy-to-LiveKit path rasterizes through CPU memory without an explicit
+   fallback reason.
+6. Move repeated envelope/budget helpers out of individual modules as adapters
+   land. No parallel TS policy layer.
+
+## Issue Backlog From This Design
+
+- `comms: add TransportEnvelope, ResourceBudget, and BufferLease Rust types`
+- `comms: wrap AIRC queue scan with resource-accounted transport adapter`
+- `comms: wrap IPC command execution with cancellation/backpressure budgets`
+- `comms: add GridTransport adapter for shared envelope/accounting`
+- `live: add media copy-count probes before video transport refactor`
+- `render: design GPU frame-handle transfer gate for Bevy to LiveKit`
+
+These are deliberately small enough for concurrent AIRC lanes. The design is
+only useful if it becomes several mergeable slices rather than one giant
+rewrite.
+
+## Acceptance Criteria
+
+- New transport work starts from the Rust `comms` traits unless it documents why
+  the shared layer does not apply.
+- Generated TypeScript reflects Rust types; no hand-written duplicate
+  envelopes.
+- Hot-path PRs report latency, bytes, copy counts, or queue depth in evidence.
+- AIRC remains a coordination/manifest substrate and never becomes the media or
+  artifact bulk path.
+- Repeated envelope, budget, and ownership logic is removed as each adapter
+  lands.

+
+**Status:** Open-question registry (2026-05-31).

+**Parents:**
+- [`docs/architecture/AI-COMMAND-NAMESPACE.md`](../architecture/AI-COMMAND-NAMESPACE.md) — the surface
+- [`docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md`](../architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md) — the daemons behind it (aspirational ceiling)

+
+## Open questions, organized by lane
+
+### Lane: Inference daemon (#109)
+
+#### Q1 — Persona priority class signaling
+
+How does a request indicate its pool class (realtime / interactive
+/ background / sentinel)?
+
+- **Matters because:** without this signal, the scheduler can't
+  tier-pool, can't enforce latency targets, can't safely run
+  background work alongside live conversation.
+- **Blocks:** SlotPool design, RequestQueue ordering.
+- **Candidates:**
+  - Reuse the existing `purpose: Option<String>` field on
+    `TextGenerationRequest`; introduce a vocabulary
+    (`"realtime"`, `"interactive"`, `"background"`, `"sentinel"`)
+  - Add `pool: Option<PoolClass>` to TextGenerationRequest
+    explicitly
+  - Set it on the persona record at registration; the daemon reads
+    persona record by `persona_id` rather than per-request
+  - Hybrid: persona record carries default, request can override
+- **Decision needed by:** #109 implementation start.
+
+#### Q2 — Continuous batching window — static or dynamic?
+
+What's the right batch-admission window per pool class?
+
+- **Matters because:** window directly trades latency for
+  throughput. Too short → low GPU utilization. Too long → realtime
+  pool overshoots its budget.
+- **Blocks:** BatchAssembler implementation.
+- **Candidates:**
+  - Static per-pool (realtime=0ms, interactive=2ms, background=20ms)
+  - Pressure-driven (more pressure → longer windows for throughput)
+  - Adaptive PID-style controller targeting pool latency budgets
+  - Hybrid: per-pool ceiling + adaptive within bounds
+- **Decision needed by:** BatchAssembler scaffold.
+
+#### Q3 — LoRA paging cost calibration
+
+How does the scheduler know how expensive each adapter's swap is?
+
+- **Matters because:** the scheduler must NOT schedule operations
+  that exceed pool latency. Hot-path swap is the prior-attempt
+  failure mode.
+- **Blocks:** LoRAPager safety.
+- **Candidates:**
+  - Boot-time calibration pass: measure swap cost per adapter
+  - Stored profile keyed by `(adapter_id, host_class)` — refresh
+    on hardware change
+  - Per-host-class lookup table for known adapter shapes
+  - Dynamic learning: measure over time, EMA-track
+- **Decision needed by:** LoRAPager implementation.
+
+#### Q4 — Adaptive quantization tier selection
+
+What algorithm picks INT4 vs INT8 vs FP16 per slot?
+
+- **Matters because:** wrong tier under pressure either OOMs or
+  ships unnecessarily degraded quality.
+- **Blocks:** AdaptiveQuantizer.
+- **Candidates:**
+  - Static pool → tier mapping (realtime=INT8, background=INT4)
+  - Continuous pressure-driven (VRAM utilization above X% → drop
+    tier)
+  - Per-persona preference
+  - Hybrid: persona default + pressure override + pool floor
+  (realtime never drops below INT8)
+- **Decision needed by:** AdaptiveQuantizer scaffold.
+
+#### Q5 — Speculative warming prediction model
+
+How does the daemon predict which persona to pre-page?
+
+- **Matters because:** wrong prediction wastes paging + may evict
+  needed adapters. Right prediction hides paging latency.
+- **Blocks:** SpeculativeWarmer.
+- **Candidates:**
+  - Rule-based (mention detection, recent active speaker,
+    turn-taking pattern)
+  - Learned per-room conversation-flow model
+  - Hybrid: rules for high-confidence cases, learned for the rest
+- **Decision needed by:** SpeculativeWarmer scaffold.
+
+#### Q6 — Pressure signal source per host class
+
+Where does the daemon read VRAM / RAM / GPU utilization on each
+host class?
+
+- **Matters because:** the substrate runs on macOS (Apple Silicon
+  unified memory + Intel discrete), Linux NVIDIA, Linux AMD, Linux
+  Intel — each has different APIs.
+- **Blocks:** PressureMonitor.
+- **Existing:** `SubstrateGovernor` (CBAR-SUBSTRATE-ARCHITECTURE.md)
+  already polls some signals. Extend or replicate?
+- **Candidates:**
+  - SubstrateGovernor publishes a unified pressure bus event;
+    InferenceScheduler subscribes
+  - InferenceScheduler queries Governor on demand
+  - Each adapter reports its own per-device pressure (NVML for
+    NVIDIA-backed adapters, etc.) and the scheduler aggregates
+- **Decision needed by:** PressureMonitor scaffold.
+
+#### Q7 — Base-model sharing under model-swap pressure
+
+When batches of conflicting models arrive (some need Qwen, some
+need Llama), how does the scheduler decide which model to keep
+warm?
+
+- **Matters because:** if model swaps happen frequently, all the
+  base-model-sharing benefits disappear.
+- **Blocks:** BaseModelSharing.
+- **Candidates:**
+  - LRU on model bytes
+  - Pinned model pool (most-used model always warm)
+  - Pool-class-driven (realtime pool's model always wins)
+  - Dynamic sizing based on request distribution over recent window
+- **Decision needed by:** BaseModelSharing implementation.
+
+---
+
+### Lane: Cross-grid inference (#108)
+
+#### Q8 — Peer discovery + capacity advertising
+
+How does the local daemon discover which peers run which models warm
++ what capacity they have available?
+
+- **Matters because:** the M5 → 5090 case requires the M5 to KNOW
+  the 5090 is available and willing.
+- **Blocks:** AircRemoteInferenceAdapter routing.
+- **Candidates:**
+  - Periodic capacity beacon over airc (publish current
+    `inference/capacity` per peer)
+  - On-demand probe (ask all peers "do you have X warm?")
+  - Centralized scope-wide capacity registry
+  - Hybrid: long-poll capacity stream + on-demand verification
+- **Decision needed by:** AircRemoteInferenceAdapter scaffold.
+
+#### Q9 — Persona identity projection on remote peer
+
+Joel's persona "Paige" lives on her local Mac. When she opens an
+inference handle on the 5090 over airc, what identity does she
+have on the 5090?
+
+- **Matters because:** persona scope checks in the handle store +
+  in RAG sources require an identity. Cross-persona leakage is a
+  defense-in-depth concern.
+- **Blocks:** AircRemoteInferenceAdapter session shape.
+- **Reference:** [[personas-are-citizens-airc-is-identity-provider]]
+- **Candidates:**
+  - Project Paige's airc peer_id directly (the substrate identity
+    primitive already crosses machines)
+  - Create a temporary "remote-session" persona scoped to this
+    handle
+  - The 5090 holds a "remote-proxy" persona on Paige's behalf, scoped
+    by her peer_id
+- **Decision needed by:** AircRemoteInferenceAdapter scaffold.
+
+#### Q10 — Backpressure when grid is saturated too
+
+What happens when local slots AND all reachable grid peers are
+saturated?
+
+- **Matters because:** the substrate must degrade gracefully, not
+  hang.
+- **Blocks:** RouteSelector backpressure path.
+- **Candidates:**
+  - Queue locally with extended wait + emit backpressure event
+  - Return typed "no capacity" error; let the caller (persona /
+    sentinel) decide
+  - Fall back to heuristic adapter with a clear "degraded" flag in
+    the response
+- **Decision needed by:** RouteSelector design.
+
+---
+
+### Lane: ai/* namespace consolidation (#106)
+
+#### Q11 — Migration path for existing `inference/*` + `embedding/*` callers
+
+How do we move existing top-level command consumers under `ai/*`
+without breaking them?
+
+- **Matters because:** the namespace is the wrong shape today; we
+  want to fix it without a flag day.
+- **Blocks:** #106.
+- **Candidates:**
+  - Dual-route at the kernel: both old prefix + new prefix accepted
+    for a deprecation window
+  - Hard-fail rename: bump major + migrate all callers in one PR
+  - Symlinks at the command registry level + log warnings
+- **Decision needed by:** #106 start.
+
+#### Q12 — Per-modality `ai/capacity` shape
+
+`inference/capacity` returns one number today (LLM slots). The
+unified `ai/capacity` should report vision / audio / embedding /
+classical-ML caps separately. What's the wire shape?
+
+- **Matters because:** callers can't reason about cross-modality
+  scheduling without per-modality numbers.
+- **Blocks:** scheduler cross-modality decisions, `ai/capacity`.
+- **Candidates:**
+  - Flat map: `{ "llm": 4, "vision": 2, "audio": 1, "embedding": 8 }`
+  - Structured per-modality (slots, queued, average_latency_ms)
+  - Per-pool-class subdivision within each modality
+- **Decision needed by:** namespace consolidation.
+
+---
+
+### Lane: Observability (substrate-wide)
+
+#### Q13 — Replay parity across modalities
+
+`ReplayRagSource` exists today for RAG. Do `ReplayInferenceSource`,
+`ReplayVisionSource`, `ReplayAudioSource` follow the same shape?
+
+- **Matters because:** AIs running adversarial review need to
+  replay an entire persona turn (RAG + prompt + inference + vision
+  + …) deterministically.
+- **Blocks:** full-turn replay.
+- **Candidates:**
+  - One replay shape per modality, each modeling its own source
+    contract
+  - Single unified `Replay<ModalitySource>` with parametric type
+  - Composite `ReplayPersonaTurn` that drives multiple replay
+    sources from a single JSONL trace
+- **Decision needed by:** task #56 (wire persona turn capture).
+
+#### Q14 — Schema versioning for capture traces
+
+Today's JSONL traces have no schema version. As fields evolve, old
+traces become unreplayable.
+
+- **Matters because:** replay is a product requirement; broken
+  replay defeats it.
+- **Blocks:** long-term replay viability.
+- **Candidates:**
+  - `version` field on every capture event
+  - Schema-tag at the trace head; rejector for incompatible
+  - Migration adapters per version pair
+- **Decision needed by:** when replay starts being used in CI.
+
+#### Q15 — Capture sink composition
+
+Today a sink is one of Noop / JSONL / InMemory. What about
+multi-sink (JSONL + IPC publish + InMemory at the same time)?
+
+- **Matters because:** a mechanic-shop session might want
+  live-streamed IPC + on-disk trace + in-memory inspection
+  concurrently.
+- **Blocks:** richer mechanic-shop workflows.
+- **Candidates:**
+  - `BroadcastCaptureSink` wrapping a Vec<Arc<dyn CaptureSink>>
+  - Sinks compose via a fan-out trait combinator
+  - Single global capture bus that sinks subscribe to
+- **Decision needed by:** when mechanic-shop work starts.
+
+---
+
+### Lane: Hardware + memory hierarchy
+
+#### Q16 — Apple unified-memory accounting
+
+On Apple Silicon (M1+), unified memory is shared between CPU and
+GPU. How does the scheduler reason about this vs the discrete-VRAM
+model?
+
+- **Matters because:** the M5 target IS unified memory. Wrong
+  accounting drives wrong eviction / batching decisions.
+- **Blocks:** Apple-class scheduler tuning.
+- **Existing:** `SubstrateGovernor` has some unified-memory
+  awareness.
+- **Candidates:**
+  - Single pressure signal across CPU + GPU work
+  - Separate accounting with explicit "shared pool" budget
+  - Per-adapter declaration of UMA-vs-discrete behavior
+- **Decision needed by:** Apple Silicon performance work.
+
+#### Q17 — KV cache eviction policy across pool classes
+
+When VRAM tightens, KV cache eviction is the highest-leverage
+pressure relief. Which slots lose their cache first?
+
+- **Matters because:** evicting an active realtime conversation's
+  KV is a quality cliff.
+- **Blocks:** PressureMonitor eviction policy.
+- **Candidates:**
+  - LRU across all slots
+  - LRU within pool class; background pool always evicted first
+  - Eviction never targets realtime pool (hard pin)
+  - Hybrid: LRU within pool, pool-class priority for cross-pool
+- **Decision needed by:** PressureMonitor design.
+
+---
+
+### Lane: Multi-modal pipelines
+
+#### Q18 — Vision crutch latency budget
+
+When a text-only LLM persona needs to "see" via
+`ai/vision/describe` → text → RAG → `ai/inference/generate`, the
+vision step adds latency. How does the persona's pool class flow
+through?
+
+- **Matters because:** if Paige's realtime turn needs vision and
+  vision goes to the background pool, her turn missed its budget.
+- **Blocks:** vision-as-crutch integration.
+- **Candidates:**
+  - Pool class propagates through the chain — vision call inherits
+    Paige's realtime class
+  - Vision has its own pool independent of caller
+  - The orchestrating layer (PersonaCognition) explicitly threads
+    pool class
+- **Decision needed by:** vision-crutch implementation.
+
+#### Q19 — Multi-modal model decomposition
+
+Native multimodal Qwen (the M5 target) handles vision INSIDE the
+LLM forward pass. CNN crutches handle vision via a separate
+classifier model. When does the scheduler pick which?
+
+- **Matters because:** native multimodal is higher quality but
+  requires the multimodal model to be loaded; CNN crutch is more
+  flexible but loses cross-modal reasoning.
+- **Blocks:** multimodal vision strategy.
+- **Candidates:**
+  - Persona preference (some pin native, some pin crutch)
+  - Capability check at handle open (multimodal model available
+    → use native; else crutch)
+  - Per-request hint via `purpose`
+- **Decision needed by:** native-multimodal Qwen integration.

+
+### Lane: Realistic lane build (#109 floor)
+
+These questions land alongside the new
+[`INFERENCE-LANES-REALISTIC.md`](../architecture/INFERENCE-LANES-REALISTIC.md)
+doc and are the ones the realistic-lane MVP cut has to answer
+before the code goes in.
+
+#### Q21 — llama.cpp batched-decode finish-reason cleanliness
+
+Does the vendored llama.cpp expose per-sequence finish reasons
+(EOS / stop sequence / length) cleanly from batched decode? If
+not, the coordinator must track sequence-by-sequence state
+outside the adapter.
+
+- **Matters because:** the coordinator returns per-handle
+  responses; if it can't tell which lane finished, batching
+  breaks down.
+- **Blocks:** Step 4 of the realistic-lane build (continuous
+  batching in LlamaCpp adapter).
+- **Candidates:**
+  - Direct llama.cpp API audit + use what's there
+  - Wrapper layer that tracks per-sequence state in the adapter
+  - Single-sequence fallback when batched-decode lacks the data
+- **Decision needed by:** before LlamaCpp coordinator wiring.
+
+#### Q22 — Model-pick policy for the realistic target
+
+What `model_for_tier(tier)` mapping does the substrate ship for
+the realistic floor?
+
+- **Matters because:** the substrate must pick something
+  reasonable out of the box on every supported host class — a
+  CPU-only laptop user shouldn't have to configure anything to
+  get a usable persona.
+- **Blocks:** realistic-lane defaults.
+- **Candidates** (draft, Joel decides):
+  - Apple Silicon UMA ≥ 16 GB: Qwen-2.5-7B Q4_K_M
+  - Apple Silicon UMA 8–16 GB: Qwen-2.5-3B Q4_K_M
+  - Mac Intel + Metal ≥ 16 GB: Qwen-2.5-3B Q4_K_M
+  - CPU-only ≥ 8 GB: Gemma-2-2B Q4_K_M (best creative density at small size)
+  - CPU-only < 8 GB: heuristic adapter fallback
+- **Decision needed by:** before realistic-lane MVP ships.
+- **Lives in:** `governor/model_policy.rs` (or similar)
+
+#### Q23 — KV cache precision switch (FP16 ↔ INT8)
+
+When KV cache tightens, does the coordinator silently switch to
+INT8 KV via `inference/kv_quant.rs` (already in tree)?
+
+- **Matters because:** this is the adaptive-resolution dial in
+  miniature. Cheap, big quality preservation, gains ~50% effective
+  KV capacity.
+- **Blocks:** PressureBroker integration for the realistic build.
+- **Candidates:**
+  - Always-on (default INT8 from the start; saves memory by default)
+  - Pressure-driven (FP16 when comfortable; INT8 under Warning;
+    INT4 under High)
+  - Per-lane-class (Pinned lanes stay FP16, Graceful drop to INT8
+    under pressure, Hard always INT8)
+- **Decision needed by:** PressureBroker integration step.
+
+#### Q24 — TaskKind change mid-session
+
+A lane's TaskKind changes during a session (Chat → CodingLarge
+when the user pastes a 100-line file). Can the lane upgrade in
+place?
+
+- **Matters because:** if no in-place upgrade, the user closes +
+  reopens; this is a UX hiccup but tractable. In-place upgrade is
+  smoother but adds complexity.
+- **Blocks:** Step 1 lane API.
+- **Candidates:**
+  - A: Lane is immutable; persona closes + reopens (MVP)
+  - B: `ai/inference/upgrade-lane { handle, new_task }` command that
+    re-acquires the lease at the new budget
+  - C: Coordinator detects need from input length, auto-upgrades
+- **Decision needed by:** Step 1 lane API design. Likely A for MVP,
+  B as a near-follow-up.
+
+#### Q25 — Idle-lane KV demotion policy
+
+When a lane goes idle (no requests for N seconds), does the
+coordinator preemptively demote KV cache to Warm → Bench tier?
+
+- **Matters because:** active conversation needs Fast tier KV;
+  idle lanes hogging Fast tier starve fresh activations. But
+  premature demotion costs latency on re-activation.
+- **Blocks:** PressureBroker lane interaction.
+- **Candidates:**
+  - Only-on-pressure (lazy; idle lanes stay in Fast until pressure)
+  - Time-driven (idle > N seconds → demote regardless of pressure)
+  - Hybrid (small idle window + pressure trigger)
+- **Decision needed by:** PressureBroker lane integration.
+
+---
+
+### Lane: Prior-attempt forensics
+
+#### Q20 — Recover the prior attempt's actual failure logs
+
+Joel's "we wrote about this and attempted the same thing with
+adapters before. It was rather shitty" implies prior work + logs +
+post-mortems that aren't currently in the docs.
+
+- **Matters because:** repeating mistakes is unforgivable when the
+  documentation exists. Even partial recovery of the failure modes
+  saves implementation time on #109.
+- **Blocks:** Confident scheduler design.
+- **Candidates:**
+  - Search git log + branch history for adapter-paging /
+    multi-persona-inference / scheduler PRs
+  - Check older `docs/inference/` + `docs/architecture/` revisions
+  - Ask Joel for pointers
+- **Decision needed by:** #109 implementation start.
+
+---
+
+## Triage

+## How to close an item
+
+When a decision is made:
+
+1. Update the question to **Resolved** with a one-paragraph summary.
+2. Link to the PR / commit / doc where the decision lives.
+3. Move closed items to an "Archive" section at the bottom; don't
+   delete (the rationale stays useful for future reviewers).
+4. If the decision invalidates a candidate elsewhere on this page,
+   note it inline.
+
+The goal: when #109 (or any of the blocked tasks) actually starts,
+the implementer reads this doc once and knows which decisions are
+made and which they're empowered to make.

+
+**Updated**: 2026-05-16
+**Branch policy**: every change lands as `PR -> canary -> validation -> PR -> main`
+**Status**: active planning document, shared by humans and agents
+**Operating rule**: Rust owns runtime logic. TypeScript is UI, schema, generated types, and thin command/transport glue.
+**Template-first rule**: new commands must start from `tools/generator/specs/*.json` and Continuum's command generator. Manual command scaffolds are not acceptable; hand edits are for post-generation behavior only.
+**Architectural mandate**: Rust-first, GPU-first, replay-tested. No patchwork substitutes for the target architecture.
+**Runtime substrate spec**: [CBAR Substrate Architecture](../architecture/CBAR-SUBSTRATE-ARCHITECTURE.md) — the runtime/RTOS contract every Rust concern inherits. ALPHA-GAP owns sequencing; CBAR-SUBSTRATE owns the substrate behavior the lanes converge on.
+**Sensory model plan**: [Sensory Model And Experiential Plasticity Plan](../architecture/SENSORY-MODEL-AND-EXPERIENTIAL-PLASTICITY-PLAN.md)
+
+This document is the alpha/gap source of truth. Work should not proceed as disconnected chat threads, private agent branches, or parallel "gap" documents. Each implementation PR must name the issue it advances, land in `canary`, publish validation evidence, and only then be considered for promotion to `main`.
+
+As of 2026-05-13 there is exactly one alpha/gap planning file:
+`docs/planning/ALPHA-GAP-ANALYSIS.md`. New alpha/gap notes are merged here or
+deleted. Architecture references may point here, but they must not become
+parallel status ledgers.
+
+The previous 2026-05-01 alpha snapshot was useful but had become a historical log. This revision turns it into an execution plan for the current goal: **stable, GPU-first, Rust-centric Continuum with modular Docker and fast tests that do not depend on the Node/UI stack for core correctness.**
+
+## 2026-05-11 Management Reset: Rust First, No Patchwork
+
+Continuum is past the point where local fixes to Node/TS symptoms can be treated as product progress. The product is a native, highly concurrent, resource-aware AI runtime that happens to have a browser UI. The implementation posture is therefore:
+
+1. **Architecture beats remedies.** If the bug is caused by cognition, inference, resource pressure, model routing, memory, tool execution, or persona scheduling living in the wrong layer, the fix is to move the responsibility to the right Rust abstraction. Do not add another TS guardrail around a Rust/runtime concern.
+2. **Rust is the design language for runtime behavior.** New behavior under persona cognition, model selection, local inference, paging, LoRA/model residency, memory consolidation, tool parsing/execution, command execution semantics, and recovery state machines starts in Rust.
+3. **TypeScript is not the prototype layer for cognition.** TS iteration speed is not a justification. A fast prototype that stays in Node becomes permanent debt. The correct loop is Rust unit test -> Rust replay/VDD test -> canary integration -> live smoke.
+4. **No silent fallbacks.** CPU fallback, cloud fallback, empty API-key availability, generic model fallback, placeholder UUIDs, and swallowed command errors are alpha blockers unless explicitly surfaced as degraded state with a user-visible remedy.
+5. **No feature-disabling fixes.** A fix that makes tests pass by disabling local models, personas, chat, inference, telemetry, or replay is a regression unless the PR is explicitly a kill-switch PR and documents the lost capability.
+6. **No PR sediment.** PRs are not storage. A PR either merges to canary after evidence, gets rebased and completed, or is closed with the durable work moved into an issue/design doc. Long-lived PRs are technical debt.
+7. **Perfect means structurally correct, not endlessly delayed.** The expected cadence is small architectural PRs that move ownership to Rust and delete the wrong layer. "Perfect" does not mean one huge rewrite branch; it means every merged increment points at the final architecture and reduces future work.
+
+This reset supersedes "move fast and break things" thinking. Agents have enough implementation bandwidth to spend the extra hours on the correct abstraction up front. That is cheaper than debugging another patchwork system for weeks.
+
+## Alpha Definition
+
+Alpha is ready when a fresh user can install, boot, talk to personas, recover from common failures, and verify the system mostly through Rust-level tests.
+
+The non-negotiable gates:
+
+1. **GPU-first inference**: alpha-critical inference must use Metal/CUDA/Vulkan/DMR GPU paths. No silent CPU fallback.
+2. **Sensory personas are the product**: every standard persona has multimodal perception, voice/audio, avatar/control output, and WebRTC room presence. Text-only is a compatibility/degraded mode, not the alpha target.
+3. **Qwen multimodal is the local target family**: Qwen 3.5 now and Qwen 3.6 next are treated as first-class local persona targets. Vision/audio layer gaps, unsupported kernels, CPU layers, or upstream runtime limitations are owned engineering work.
+4. **Rust core owns behavior**: persona cognition, scheduling, resource pressure, paging, inference orchestration, replay, and recovery live in Rust.
+5. **Node/TS is thin**: browser UI, command adapters, schemas, generated types, and minimal transport glue only.
+6. **Docker is modular and GPU-capable**: one opaque "build/seed/start everything" container is not alpha-ready. Services need independent health, logs, restart boundaries, and GPU-visible runtime paths on machines that support them.
+7. **Fast tests first**: core work must be covered by `cargo test` or Rust integration tests before Docker/browser tests.
+8. **Canary is the sync point**: every fix is merged to `canary` first and tested there by available Mac/Windows/Linux agents.
+9. **No silent success**: health checks, install steps, inference readiness, bridge delivery, and UI restore paths must fail loud with actionable evidence.
+10. **Persona cognition TS line count trends downward**: any PR touching persona cognition must delete or shrink TS runtime logic under `src/system/user/server/` unless it is strictly UI/schema/adapter work.
+11. **Replay before live claims**: persona, RAG, tool, inference, and memory changes must include a Rust fixture/replay/unit test before "works live" is accepted.
+12. **One source of truth per runtime fact**: model definitions, provider availability, context budgets, hardware capability, config values, room identity, and command semantics must each have one canonical owner.
+
+### CBAR-Like Runtime Substrate Contract
+
+Continuum's Rust runtime must adopt the CBAR performance philosophy from
+`/Users/joelteply/Development/cambrian/cb-mobile-sdk/cpp/cbar`: small concern
+modules inherit the hard machinery from a shared substrate. The goal is not a
+literal class-for-class port; the goal is the same RTOS-style behavior:
+concurrent lanes, bounded queues, lazy shared artifacts, realtime-first
+cadence, resource admission, and handles instead of copied memory.
+
+The reusable substrate must provide:
+
+- `RuntimeFrame` / `CognitionTurnFrame`: one turn/frame object with stable keys
+  and lazy artifacts for room snapshot, RAG, model selection, prompt fragments,
+  media handles, embeddings, KV leases, LoRA leases, response envelopes, and
+  trace metrics.
+- `RuntimeModule`: a narrow Rust trait for concerns. Modules declare
+  subscriptions, lane, cadence, dependencies, and budget; they do not invent
+  their own scheduler.
+- `ResourceClass` plus `TargetSilicon`: the shipped two-axis scheduler shape.
+  `ResourceClass` describes what kind of work is being scheduled, while
+  `TargetSilicon` describes where it wants to run. Docs may say "lane"
+  informally, but implementation should reuse these shipped enums rather than
+  invent `ResourceLane`.
+- `ArtifactHandle` / leases: module boundaries pass ids, hashes, offsets,
+  texture ids, buffer leases, model residency leases, KV page ids, and LoRA
+  page ids. Bulk payloads stay resident in the owning pool.
+- dependency wakeups: work runs when required artifacts become ready, not
+  because a global FIFO happened to drain.
+- cadence and pressure gates: realtime work runs first; delayed work runs by
+  cadence, state delta, or explicit trigger; pressure reduces cadence,
+  precision, context, subscriber count, or modality with visible reasons.
+- built-in logs, metrics, flush, abort, shutdown, queue depth, queue time,
+  execution time, coalesced count, deferred count, and resource residency.
+- one standard VDD record emitted by the Rust substrate for every platform, so
+  Mac, Windows/RTX, Docker, and future grid nodes report comparable timing,
+  throughput, CPU/GPU, residency, silence, and bottleneck fields.
+- one-line instrumentation helpers for runtime code: scopes, marks, counters,
+  residency, deferrals, and failures should feed the standard VDD record
+  automatically. A module author should not write a custom timing harness to
+  answer whether CPU fell, GPU utilization rose, memory/power stayed bounded,
+  or throughput improved.
+
+This substrate is the base-class/OOP-equivalent discipline for Rust. Extension
+code should be short: implement the small trait, declare dependencies, and let
+the runtime provide concurrency, telemetry, pressure, wakeups, and lifecycle.
+New modules should normally be measured in a few hundred lines, not thousands.
+If a new runtime concern needs its own bespoke communications, queue,
+backpressure, retry, metrics, lifecycle, or failure-reporting system, the PR is
+exposing missing substrate work and should fix the shared substrate instead of
+growing a monolith.
+
+The first implementation PRs should not add more bespoke queues, fallback
+paths, or TS orchestration. They should converge existing Rust pieces into this
+substrate: `ServiceModule`, `MessageBus`, `SharedCompute`, `ChannelQueue`,
+`PressureBroker`, `PagedResourcePool`, model registry, and
+`llamacpp_scheduler`.
+The missing work is specifically `RuntimeFrame` / `CognitionTurnFrame` and
+formal artifact subscription/cadence/dependency declarations on top of the
+shipped substrate primitives, not a restart from zero.
+
+### Sensory Persona Product Contract
+
+Continuum's differentiator is not "chat with several text bots." The alpha product is a local sensory persona grid: users can call personas into a WebRTC room, speak to them, see them, and receive useful multimodal responses from agents that can perceive images/video/audio and drive avatar or other control outputs.
+
+Implementation consequences:
+
+- **Every standard persona declares sensory requirements.** The default requirement set includes text, vision, audio input, voice/audio output, avatar/control output, and WebRTC presence. A persona that cannot satisfy those requirements is marked `Degraded` with the missing capability, not silently treated as alpha-complete.
+- **STT/TTS are adapters, not the center.** They exist to support compatibility models and weaker hosts. The standard local model path targets multimodal models directly where possible.
+- **Qwen 3.5/3.6 are optimization targets.** The registry and runtime resolve model requirements by capability, context, memory budget, and GPU support. They do not scatter hardcoded model names or accept random provider/model drift.
+- **Qwen GPU support is an alpha contract.** Qwen 3.5 text/code and Qwen2-VL
+  vision must run through Continuum's llama.cpp/local runtime with all viable
+  layers on the required platform backend: Mac -> Metal, NVIDIA -> CUDA, and
+  AMD/Intel -> Vulkan. Unsupported Qwen layers, mmproj/audio/vision gaps, CPU
+  graph splits, or missing upstream kernels are implementation blockers to fix
+  or vendor/upstream, not reasons to route around the local runtime. The model
+  resolver must expose selected model, backend, GPU layer count, expected
+  residency, unsupported layers, and any degraded reason before a persona turn
+  starts.
+- **Open-source runtime gaps are ours to fix.** If llama.cpp, Candle training code, GGUF conversion, kernels, multimodal projectors, audio layers, or paging support are missing what Qwen needs, the work item is to fork/vendor/upstream the fix with benchmarks. "Upstream cannot" is not a final answer for open-source dependencies.
+- **No CPU crutches in the happy path.** CPU fallback is explicit degraded mode for unsupported hardware, tests, or emergency operation. It is not a performance plan for a 3090/5090/M-series target.
+- **Live media is a gate.** Video chat, avatar output, and WebRTC bridge health are alpha gates. A PR that breaks sensory persona presence must fail validation before canary promotion.
+- **Sensory model scouting is a tracked workstream.** Current Qwen3.5, Qwen3.6, Qwen2.5-Omni, Qwen3-Omni, forge/alloy, experiential plasticity, pruning, and MoE pruning work lives in the sensory model plan linked above. Runtime adoption still goes through the Rust registry and VDD gates.
+
+## Current Snapshot
+
+Reflects canary as of 2026-05-16 (post the 8-PR cognition-oxidization batch +
+PressureBroker bootstrap PR-1/2/3 + Docker tier Phase 1 + inference-grpc
+fail-closed). For each area, the "current read" is what is provably in canary,
+not what is intended. "Alpha risk" calls out the gap to the alpha gates above.
+
+| Area | Current read (canary @ 2026-05-18) | Alpha risk |
+|---|---|---|
+| AIRC collaboration | AIRC canary has public `knock` plus forward-secret `approve`/`decrypt-approval` handoff; Continuum PR #1110 pilots repo-local `.airc/` collaboration rules; agent flywheel board #1272 active with codex-main heartbeats | Queue/nudge work tracked in CambrianTech/airc#562; Continuum personas and external agent providers are not yet first-class workers on the shared queue; manager-role transition in progress this session |
+| UI room state | PR #1047 merged to `canary` for stale duplicate General tab recovery | Needs live UI reload validation before `main` promotion |
+| Docker | Phase 1 of Docker tier surface merged (#1297 — `system/docker-tier-stats` IPC + ts-rs DockerTierStats); `scripts/main-promotion-gate.sh` landed (#1399) as the canary->main per-host receipt gate; GPU profile + tier pool eviction (#1238, #1239) still open; historical bulk and mixed responsibility still in the runtime images | Docker can mask failures and slow iteration; tier pool eviction + capability-visible health are the remaining alpha lifts; main promotion still needs linux/amd64 CUDA (#1410) and linux/amd64 Vulkan receipts for the same SHA |
+| Rust core | Substantial gains this session: PressureBroker bootstrap landed (#1307 PR-1 + #1308 PR-2 IPC + #1310 PR-3 status surface); runtime lease broker added (#1313); cognition migrated for `should_respond` (#1284), `rate_proposals` (#1290/#1291/#1293), `generate_recipe` (#1298/#1301/#1303), `vision-describe` (#1292), and `generate_response` (#1398/#1400/#1402/#1407); inference-llm runtime registration landed (#1404); `PersonaTurnFrame` now carries consolidated inbox, RAG seed, response prompt, and replay schema v2 with captured prompt (#1412); ToolRegistry semantic-search oxidizer PR-1 landed (#1413) | Lane D is no longer unstarted, but the alpha-critical `persona/turn-execute` command (#1409) is still in flight; per-module hardcoded concurrency declarations still present across `core/continuum-core/src/modules/*.rs`; universal base trait + derive macro + scaffold generator (the "low-friction inheritance" triplet from CBAR-SUBSTRATE) not yet landed |
+| Node/TS | Net-negative trend this week: TS cognition deleted through oxidization stacks; `AIDecisionService.generateResponse` is now a thin Rust IPC shim and no longer owns TS slot coordination (#1402/#1407); Lane F ratchet landed for persona cognition dirs (#1401) and expanded to `src/system/ai/server` (#1406); SQLite default config landed (#1271) | Multiple TS daemons still own runtime logic that belongs in continuum-core; Lane F PR-2 still needs CI/pre-push enforcement beyond the local ratchet, and PR-3 still needs forbidden-provider/fallback scans |
+| Config/secrets | `$HOME/.continuum/config.env` is the local source of truth, but empty placeholders and per-process loading have caused false provider availability | Cloud providers can steal local turns and fail; grid nodes cannot yet receive encrypted config consistently |
+| Tests | Many tests exist; the alpha loop still overuses `npm start`/browser/Docker as proof; `no_cpu_fallback_contract.rs` regression test exists for the llama.cpp/ORT paths only — does not cover the Candle-side device selection where the orpheus + inference-grpc CPU fallbacks lived before #1314 | Slow tests hide root causes and discourage TDD; the no-CPU-fallback contract test needs widening to the whole workers tree, not just three whitelisted files |
+
+## Immediate Canary Work Packages
+
+These are the active alpha blockers exposed by the 2026-05-11 VDD runs and
+PR #1082 review. They are split so agents can work in parallel without stepping
+on each other. Each lane starts from `canary`, opens a focused PR back to
+`canary`, and posts validation evidence before merge. Assignment is explicit:
+if an agent cannot work a lane, it says so on AIRC and the lane is reassigned.
+
+| Lane | State @ 2026-05-18 | Owner | Branch | First PR | Merge gate |
+|---|---|---|---|---|---|
+| A. Rust model registry and admission | In progress | RTX/Windows lane (catalog + admission); supervision rotated from Codex PM → this manager | `feature/rust-model-registry-admission` (merged-stack), follow-ups on canary | Typed Rust catalog, capability request, resolver/admission explanation | Rust resolver tests plus missing-Qwen fail-hard test |
+| B. Installer model seeding and GPU profiles | Phase 1 landed (#1297 Docker tier surface); main-promotion release receipt script landed (#1399); GPU profile + tier-pool eviction still open (#1238/#1239); linux/amd64 CUDA receipt is tracked as #1410 | RTX/Windows Docker lane; Lane A owns registry artifact contract; Windows/WSL Claude expected to own #1410 when online | `feature/docker-gpu-profile-modular` plus receipt work per host | `model-init`/installer seeds required Qwen artifacts into the runtime model volume; per-host receipts prove Docker/GPU paths | Windows/RTX fresh install reaches model-ready state or fails loud; `scripts/main-promotion-gate.sh --check-receipts` passes only when Mac/Metal, linux/amd64 CUDA, and linux/amd64 Vulkan receipts share the promoted SHA |
+| C. VDD telemetry substrate | In progress; structured RuntimeMetric emitting from inference and persona but VDD report command not yet bound | RTX/Windows substrate; Mac/Metal adapter sub-task carried by Mac lane | `feature/rust-vdd-telemetry-substrate` | Structured timing/resource metrics flow into trace/event bus | VDD report shows first-token, tok/s, CPU, GPU, VRAM/RSS from structured data |
+| D. CBAR persona runtime frame | In progress. `PersonaTurnFrame` landed with drain-frame wrap (#1398), lazy `response_prompt` (#1400), `generate_response` Rust IPC path (#1402/#1407), inference-llm runtime registration (#1404), and replay schema v2 carrying the exact response prompt (#1412) | Lane D owner on AIRC; #1409 claimed on `feat/lane-d-persona-turn-execute` | `feature/cbar-persona-runtime-frame` / `feat/lane-d-persona-turn-execute` | Rust `PersonaTurnFrame` with lazy RAG/media/priority outputs and inbox coalescing | #1409 must produce a Rust `persona/turn-execute` command that chains drain -> frame -> response_prompt -> inference/llm/request -> prod replay record; multi-message smoke produces one consolidated turn, not per-event inference flood |
+| E. Pressure broker and paging gate | Bootstrap landed (#1307 PR-1 broker types/registry, #1308 PR-2 IPC, #1310 PR-3 status surface, #1313 runtime lease broker); paging (KV/LoRA residency) + pooled mtmd context still open | RTX/Mac runtime lanes | `feature/pressurebroker-admission-gate` (bootstrap stack merged); follow-ups branch per PR | Unified admission gate blocks unsafe backend/model/context loads | Concurrency test refuses unsafe second load and reports `Backpressured`/`Unavailable` |
+| F. TS cognition deletion ratchet | PR-1 local ratchet landed (#1401); AI server cognition shim coverage landed (#1406). Current baseline covers seven watched dirs including `src/system/ai/server` | Lane F split: ratchet owner for CI wiring + deprecated-provider scan; deletion owners refresh baseline in deletion PRs when watched LOC drops | `feature/persona-ts-deletion-ratchet` follow-ups | CI/check script enforces no new persona cognition TS and net-negative touched cognition | PR fails if verb-shaped TS cognition grows or introduces forbidden provider/fallback strings; PR-2 must wire ratchet into pre-push/CI, PR-3 adds deprecated-provider/fallback scan |
+| G. Canary PR hygiene | Active. #1408 refresh captures the 2026-05-18 canary stack and current delegation state | Codex currently claimed #1408; manager/architect reviews over AIRC | `docs/alpha-gap-refresh-1408` | This document plus issue/PR checklist cleanup | Every active PR has owner, blocker, validation command, and canary target; stale canary PRs (#1085/#1071/#1026) are triaged instead of left as failed-smoke sediment |
+| H. Substrate governor + tiered genome cache | **Proposed** — design landed via continuum#1327. 7-PR implementation sequence: governor types → tier stores → recall API → composer+speculator → foundry skeleton → sentinel skeleton → sharing-protocol local-first | **Needs owner claim** | `feature/substrate-governor-genome-cache` | `SubstrateGovernor` + `HardwareClass` + hardware detection at boot | Same Rust binary writes different policy on MacBook Air vs RTX 5090; VDD records prove different tier sizes / concurrency / speculation aggressiveness |
+
+Adjacent active workstream not in the lane table:
+
+- **GRID-INFERENCE-ROUTING** — PR-1 (inference capability announcer + probe +
+  registry) in flight on `feat/grid-inference-routing-pr2-announcer`. This is
+  the grid-side counterpart of Lane A: Lane A says which model the request
+  needs, GRID-INFERENCE-ROUTING says which peer can serve it. Owner: airc-8a5e.
+  Tracked under § 7 (AIRC And Continuum Internal AI Collaboration) below.
+- **ToolRegistry semantic search oxidizer (#1411)** — PR-1 landed as #1413
+  (pure types, cosine similarity, threshold). Follow-ups should mirror the
+  Rust oxidizer cadence used by `check_redundancy` and `generate_response`:
+  Rust cache + IPC handler, TS shim, then dead-TS deletion.
+
+Lane claim updates as of 2026-05-18:
+
+- Lane A has shipped a Rust crate skeleton — `model_registry/` exists in
+  `core/continuum-core/src/`, with curated catalog rows and an
+  admission resolver — but it is **NOT shipped** in the sense of "alpha
+  contract met." Live UI QA on 2026-05-18 19:18Z surfaced the failure
+  mode: `Vision AI error: model id 'Qwen/Qwen2-VL-7B-Instruct-GGUF' not
+  in registry — add it to models.toml`. 20 personas, 0 responses. The
+  Rust crate's "canonical" status is contradicted by 5 other sources of
+  truth (see "Multi-source-of-truth merge gate" in the Lane A section
+  below for the full inventory + hard gate). Open Lane A blockers:
+  delete `models.toml`, delete or auto-generate `src/shared/models.json`
+  and the `ModelRegistry.ts` variants, surface missing-model as a typed
+  UI failure (never silence), and prove vision works against an
+  initialized 20-persona room.
+- Lane B Phase 1 landed (#1297 `system/docker-tier-stats` IPC + ts-rs
+  `DockerTierStats`). Capability-visible health and tier-pool eviction
+  (#1238/#1239) are the next Lane B PRs; both should consume the Lane A
+  registry artifact contract, not invent a parallel one.
+- Lane C structured `RuntimeMetric` events emit from inference paths, but the
+  `vdd-report-command` step (Lane C PR sequence step 3) is not yet bound. As a
+  result, "VDD" is still mostly read from logs rather than from a single
+  command's structured output. RAG source tracing and `SEAM_RAG_COMPOSE`
+  remain joint with Lane D.
+- **Lane D is now the active critical path rather than an unstarted lane.**
+  `PersonaTurnFrame` can wrap drained inboxes, expose a response prompt, and
+  emit replay records whose v2 schema carries the exact prompt that fed
+  inference (#1398/#1400/#1412). `generate_response` now admits and executes
+  through Rust (#1402/#1407), and `inference-llm` is registered at runtime
+  (#1404). The next blocker is #1409: a Rust `persona/turn-execute` command
+  that chains the pieces in one Rust call and writes the prod replay record.
+- Lane E bootstrap landed (#1307 / #1308 / #1310 / #1313). The remaining lane
+  scope is paging (KV/LoRA residency, pooled mtmd context, eviction policy)
+  and **deletion of pre-broker concurrency hacks** that still bypass the
+  broker. Concrete example pinned for deletion:
+  `core/inference-grpc/src/main.rs` — `get_num_workers()` reads
+  `INFERENCE_WORKERS` from `~/.continuum/config.env` and otherwise picks a
+  worker count from system memory at startup. Both branches are exactly the
+  "we do not hard code" / "they code in tokio not whatever their fee fees say"
+  anti-pattern. PressureBroker owns concurrency; this function should be
+  deleted and the worker count derived from broker leases.
+- Lane F has been progressing through manual deletion (rate_proposals adapter
+  zero-callers delete, generate_recipe shim collapse, #1306 cognition cap
+  lift, #1309 TS suppression rip — ~2500 LOC TS removed this session). The
+  mechanical ratchet itself (the CI gate that prevents *new* verb-shaped TS)
+  has not yet landed. Until it does, the deletion progress is reversible.
+- Lane G refresh in flight: this document, the supporting doc cross-links
+  (CBAR-SUBSTRATE precedence rule added), and the lane status table you are
+  reading.
+- Lane H proposed via continuum#1327
+  ([GENOME-FOUNDRY-SENTINEL.md](../architecture/GENOME-FOUNDRY-SENTINEL.md)).
+  Owns the artifact-sharing economy layered on top of CBAR-SUBSTRATE:
+  tiered genome cache (L1–L5), `WorkingSetManager` + page faults, foundry
+  (JIT for SOTA absorption), sentinel-AI (profile-guided optimization
+  from lived traces), demand-aligned recall, composer + speculator, and
+  the `SubstrateGovernor` (DVFS for AI — same Rust code on MacBook Air
+  and RTX 5090, different governor policy). Sibling to Lane E
+  (`PressureBroker`): broker owns admission; governor owns sizing.
+  Needs owner claim; 7-PR sequence detailed in the GENOME-FOUNDRY-SENTINEL
+  doc's Part 13.
+
+### Lane A: Rust Model Registry And Admission
+
+**Problem**: model/provider facts are scattered, cloud/local availability can be
+misreported, and the Windows/RTX VDD run proved the CUDA stack can be healthy
+while no local Qwen model exists and personas silently produce zero replies.
+
+**Design**:
+
+- Rust owns `ModelRegistry`, `ModelRequirement`, `ModelCandidate`,
+  `ModelArtifact`, `ProviderKind`, `LocalRuntimeKind`, and `AdmissionDecision`.
+- Runtime callers request capabilities: modalities, minimum intelligence tier,
+  context window, tool support, latency class, memory budget, GPU requirement,
+  family preference, and explicit override.
+- The registry is a curated whitelist of vetted artifacts. Hugging Face/foundry
+  discovery can populate candidates, but runtime admission only selects vetted
+  rows with known template, license, backend, quantization, memory estimate,
+  modality metadata, and forge status.
+- Local chat inference is `LocalRuntime` through the llama.cpp/Qwen adapter
+  stack. Candle is for training/LoRA/forge paths, not persona chat inference.
+- Cloud providers remain adapter kinds. They do not steal turns unless their key
+  is non-empty, health checked, and explicitly admitted for that request.
+
+**Owned files/modules**:
+
+- `core/continuum-core/src/model_registry/`
+- `core/continuum-core/src/inference/`
+- `core/continuum-core/src/ai/`
+- `core/continuum-core/src/persona/cognition_io.rs`
+- generated `ts-rs` types under `protocol/typescript/`
+
+**PR sequence**:
+
+1. `model-registry-types`: Rust enums/structs plus `ts-rs` exports.
+2. `model-registry-catalog`: curated Qwen 3.5/2-VL rows and artifact metadata.
+3. `model-admission`: resolver returns selected candidate plus rejected
+   alternatives and resource explanation.
+4. `missing-model-fail-hard`: no local Qwen yields typed unavailable state and
+   user/actionable remedy, never silence.
+
+**TDD**:
+
+- `cargo test --package continuum-core model_registry`
+- exact model pin, family preference, `>=` intelligence/context requirement, GPU
+  required, no artifact present, and cloud key empty cases.
+
+**VDD**:
+
+- Fresh machine with no model file reports `Unavailable(MissingArtifact)` in
+  structured status and chat smoke sees a visible failure.
+- Machine with Qwen artifact selects local runtime, records memory projection,
+  and starts inference without CPU fallback.
+
+**Deletion targets**:
+
+- duplicate TS model maps/context windows
+- free-form provider/model strings in persona seed/runtime paths
+- stale local-model fallback branches and any forbidden provider tombstones
+
+**Multi-source-of-truth merge gate (added 2026-05-18 from live UI QA)**:
+
+Lane A is NOT shipped — and any claim it is "first wave done" is contradicted
+by the live UI failure mode observed at 2026-05-18 19:18Z: `Vision AI error:
+model id 'Qwen/Qwen2-VL-7B-Instruct-GGUF' not in registry — add it to
+models.toml`. That error message admits the architecture violation: a
+`models.toml` separate from the Rust `model_registry/` crate is a parallel
+source of truth, and 20 personas produced zero responses because the TS side
+asked for a model that the Rust side's TOML config didn't have.
+
+Inventoried sources of model-definition truth as of 2026-05-18:
+
+1. `core/continuum-core/src/model_registry/` — Rust crate (THE canonical owner)
+2. `core/continuum-core/config/models.toml` — Rust-side config file (DELETE)
+3. `src/shared/models.json` — TS source (DELETE or auto-generate from #1)
+4. `src/shared/ModelRegistry.ts` — TS source (DELETE or auto-generate from #1)
+5. `src/system/shared/ModelRegistry.ts` — TS variant in some worktrees (DELETE)
+6. `protocol/typescript/inference/ModelRegistry.ts` — generated (regen from #1 only)
+
+The .d.ts files at `src/dist/shared/generated/cognition/ResolvedModel.d.ts`
+and `src/dist/system/user/server/modules/PersonaResponseGenerator.d.ts`
+explicitly call `models.toml` "the canonical source" — that comment is the
+documentation of the bug. The Rust crate `model_registry/` is supposed to
+own the truth; the TOML and TS variants must be either deleted or generated
+from the crate, never hand-edited.
+
+Lane A merge gate (hard):
+
+- `core/continuum-core/config/models.toml` is DELETED. Model catalog
+  rows live in Rust code under `model_registry/`, not in a config file.
+  Model definitions are CODE (a curated catalog the engineer commits to),
+  not CONFIG (something an operator edits at runtime).
+- `src/shared/models.json` and any hand-edited `ModelRegistry.ts` files are
+  either DELETED or regenerated from the Rust crate via `ts-rs`. Editing
+  them by hand is forbidden — the generator overwrites edits.
+- The Rust resolver MUST resolve `Qwen/Qwen2-VL-7B-Instruct-GGUF` (and all
+  other models any persona references) from the curated catalog with NO
+  config-file fallback. If a persona requests a model the catalog doesn't
+  vet, the resolver returns `Unavailable(NotInCatalog)` with an actionable
+  remedy directing the engineer to add a curated row to the Rust catalog
+  — never "add it to models.toml" because the TOML must not exist.
+- "Add it to models.toml" as an error suggestion is ALSO a regression — any
+  error message that recommends editing a config file outside `model_registry/`
+  fails the gate.
+- Capability-driven admission, not exact-string match. Personas request
+  capabilities (vision-capable Qwen-class) and the registry picks the best
+  vetted candidate. Persona seed should not hardcode `Qwen/Qwen2-VL-7B-Instruct-GGUF`
+  as a string — that's another flavor of multi-source-of-truth (the persona
+  seed becomes source #7).
+
+Test for "Lane A is done":
+
+- Grep proves only `core/continuum-core/src/model_registry/` defines
+  model rows in source. No TOML/JSON/YAML/.ts file declares a model.
+- 20 personas, vision call: every one of them gets either a typed response
+  or `Unavailable(specific reason)` in the UI — none silently produce zero
+  output.
+- Browser smoke at `http://localhost:9000/chat/general`: invoke vision on a
+  Qwen2-VL persona, observe the response or a structured failure in the
+  UI, not silence.
+
+Until ALL of the above hold, Lane A is open and any other PR that touches
+model selection, inference admission, or model resolution is patching
+around the real bug.
+
+### Lane B: Installer Model Seeding And GPU Profiles
+
+**Problem**: Windows/RTX had CUDA containers ready, low CPU, and available VRAM,
+but no Qwen model was mounted. The runtime stayed silent instead of becoming
+model-ready or failing loud.
 
-**Updated**: 2026-04-17
-**Status**: **PR #891 (feature/inference-perf) closing.** Docker Model Runner is THE inference runtime (Metal Mac, CUDA Windows/Linux). Candle off chat routing. ORM abstraction sealed (handles not URLs). SQLite default (postgres opt-in). Full matrix GREEN: M5 Mac × {Docker, npm}, BigMama Win/WSL2 × Docker. Zero API keys required for first chat. Image pipeline: dev builds on metal → pushes to ghcr → CI validates (never builds). 4 personas chat via DMR GPU on both platforms.
-**Branch**: `feature/inference-perf` → merging to `main`
+**Design**:
+
+- Add an explicit `model-init` responsibility for required alpha artifacts.
+- Seed required local Qwen artifacts into the same volume/bind mount the Rust
+  runtime reads.
+- Separate Docker profiles: `gpu`, `ui`, `live`, `grid`, `forge`, `devtools`.
+- Pin GPU images and make backend capability visible at health check time.
+
+**Owned files/modules**:
+
+- `setup.sh`, install scripts, and docs install paths
+- `docker-compose*.yml`
+- Docker image build/push scripts
+- `core/continuum-core/src/model_registry/artifacts.rs`
+
+**PR sequence**:
+
+1. `model-init-profile`: separate model prewarm/download service.
+2. `qwen-seed-contract`: required local model list comes from Rust registry
+   artifact metadata, not shell hardcoding.
+3. `windows-rtx-install-vdd`: Windows GPU install smoke with model-ready proof.
+
+**TDD**:
+
+- shell/unit checks for model volume path resolution
+- Rust artifact resolver tests for missing, partial, corrupt, and ready states
+
+**VDD**:
+
+- Windows/RTX: cold start, first token, tok/s, CPU%, GPU%, VRAM, RSS.
+- Mac/Metal: same metrics, plus Metal layer offload evidence.
+- No model present: install exits or health reports explicit missing artifact in
+  less than 30 seconds.
+
+**Deletion targets**:
+
+- one-off model download code in TS/server startup
+- Docker paths that bypass Continuum's adapter/router substrate
+- opaque bulk startup scripts that hide which service failed
+
+### Lane C: VDD Telemetry Substrate
+
+**Problem**: timing, CPU/GPU utilization, tok/s, memory growth, and RAG evidence
+are still partly ad hoc logs. That makes validation slow and makes realtime
+behavior hard to reproduce.
+
+**Design**:
+
+- Rust emits structured `ValidationTrace`/`RuntimeMetric` events.
+- `CognitionTrace` gets seams for RAG composition, model admission, inference
+  init, first token, steady decode, post-process, and recorder persistence.
+- Metrics are emitted through the event bus and recorder fixtures. Stdout/stderr
+  text is local debugging output only, not the validation API.
+- One-liner timing guards are available to Rust modules so every new subsystem
+  gets timing and metadata with almost no code.
 
-This document is the **single source of truth** for remaining work. Each phase is ordered by dependency — later phases build on earlier ones. Every open GitHub issue is mapped to exactly one phase. Issues are breadcrumbs on the path to fruition — not a backlog to dread.

+**PR sequence**:
 
-## What Changed Since April 6 (PR #891 Session — 2026-04-16/17)
+1. `trace-rag-compose`: add `SEAM_RAG_COMPOSE` and RAG source hashes.
+2. `trace-inference-metrics`: first-token, tok/s, backend, layer offload,
+   CPU-degraded and GPU-required status flags.
+3. `vdd-report-command`: command emits a compact machine-readable VDD report.
 
-### Architecture Pivots
-- **Docker Model Runner = chat inference runtime.** DMR via Docker Desktop: Metal on Mac (~50 tok/s), CUDA on Windows/Linux (~237 tok/s). Candle relegated to training/LoRA only. No silent CPU fallback — hard error with install hint. (#905, closed)
-- **ORM abstraction sealed.** Callers pass opaque handles (`@main`, `@persona:<slug>`, `@metrics`), never URLs/paths/SQL. Rust resolves handles to backends via `entity_schemas.json` (build-time codegen from TS decorators). SQLite default; postgres opt-in via `--profile postgres`. Phase 2 complete (steps 1-4).
-- **Mac Option B.** Native continuum-core on host (Metal) + Docker support services. TCP listener (port 9100) bridges containerized node-server to native core via `host.docker.internal`. Docker VM sized to PHYS - 18GB headroom (not 80%).
-- **Windows Docker Desktop.** DMR reachable from containers at `model-runner.docker.internal` (not localhost:12434). CUDA backend requires Docker Desktop Settings → AI toggles (not scriptable yet, #910).
+**TDD**:
 
-### Infrastructure
-- **CI validates, doesn't build** (#906, closed — pipeline in place). `push-image.sh` on metal hardware → ghcr stages images → CI pulls + validates. Image-coverage gate checks `:pr-<N>` tags exist.
-- **Cross-mode collision detection.** `npm stop` kills BOTH Docker stack AND native processes. `npm start` detects if Docker stack already running (and vice versa). Port pre-flight fails fast on 9001/9100 instead of late EADDRINUSE.
-- **Heartbeat pre-flight.** Detects stale/duplicate native continuum-core-server on Mac. Fails loud with kill recipe.
+- recorder fixture tests for success and failure traces
+- RAG replay test proves source hashes and context can be inspected
+- inference adapter unit test with injected timings

-| [#566](https://github.com/CambrianTech/continuum/issues/566) | **Tab reconnection — tabs multiply, sessions orphaned** | PARTIAL | CLI now works so browser detection on `npm start` can refresh existing tabs. Root cause of duplicate tabs: CLI was broken (generator main blocks in esbuild). Fixed. Remaining: proper session rebinding on WebSocket reconnect. |
-| [#565](https://github.com/CambrianTech/continuum/issues/565) | **WSL2 auto-start on boot** | PARTIAL | wsl-boot.sh fixed (uses LAN gateway DNS, not 8.8.8.8). PR #581 merged. Remaining: Windows scheduled task setup, `generateResolvConf=false` auto-config. |

-## The Inference Design Goal — Multi-Persona Live Chat at Low Latency
-
-> **"We should be able to have a few ais in a live chat at LOW latency, focus on that."** — Joel, 2026-04-15
-
-This is THE workload the whole stack must serve. Not single-persona batch inference. Not benchmark-leaderboard throughput. **3-5 AI personas in live voice+video chat simultaneously**, with the full sensory pipeline (Bevy avatar render, Whisper STT, Piper TTS, LiveKit WebRTC encode/decode) running concurrently on the same machine.
-
-**Proven on this machine today**: 10ish AI chat (14 tested, strains the machine — all but 4 were cloud inference). That's the current ceiling with mostly-cloud backends. The target raises ALL of those to native local inference running at conversation pace.
-
-**Why Qwen3.5-4B+ is the pick:** [`project_m5_is_primary_audience.md`](../../memory/project_m5_is_primary_audience.md) — forged specifically to fit the concurrent-sensory slot on Apple Silicon unified memory. Q4_K_M ≈ 2.6GB per instance, KV shared via continuous-batching scheduler (`n_seq_max` sequences in ONE Context), leaves room for Bevy + Whisper + Piper + LiveKit all co-resident.
+**VDD**:
 
-**Audience tier (BMW M4 / Corvette / Ford Focus analogy):**
-- Primary: MacBook M3-M5 Pro/Max (BMW M4)
-- Entry: MacBook Air (BMW 2 Series) — aspirational, must work
-- Desktop enthusiast: Nvidia RTX 3090+ (Corvette / Mustang)
-- Non-audience: ThinkPads without GPU, integrated-only, pre-Apple-Silicon (Ford Focus)
-
-**Go-live is possible before the full vision-Qwen3.5 landing** (stopgap: text-Qwen3.5 + sensory bridges via `VisionDescriptionService`, Whisper, Piper/Orpheus — already in the codebase). But vision-Qwen3.5 is quickly needed post-launch and NOT insurmountable because **factory + sentinel-ai were built for this exact purpose** (PR891's parent narrative). Forging vision-enabled variants per device tier is the post-launch track.
-
-### Cross-referenced issues
-
-This goal cuts across phases; the work is tracked here:
-
-| # | Phase | Role in the goal |
-|---|---|---|
-| [#582](https://github.com/CambrianTech/continuum/issues/582) | Phase 2 | Native multimodal pipeline — three parallel streams LISTEN+THINK+SPEAK, <2s latency for capable models |
-| [#799](https://github.com/CambrianTech/continuum/issues/799) | Phase 2 | Qwen3.5-Omni native audio — skip VAD→STT→LLM→TTS entirely |
-| [#800](https://github.com/CambrianTech/continuum/issues/800) | Phase 2 | `continuum-ai/whisper-forged` — forged STT model |
-| [#801](https://github.com/CambrianTech/continuum/issues/801) | Phase 2 | Per-persona TTS voice cloning |
-| [#652](https://github.com/CambrianTech/continuum/issues/652) | Phase 12 | Sub-100ms vision + real-time audio inference for personas |
-| [#649](https://github.com/CambrianTech/continuum/issues/649) | Phase 12 | LLaVA-style vision encoder — bolt-on vision via projection layer training |
-| [#650](https://github.com/CambrianTech/continuum/issues/650) | Phase 12 | Whisper-style audio encoder — hearing + speech natively |
-| [#579](https://github.com/CambrianTech/continuum/issues/579) | Phase 12 | Vision model forging — feature detector pruning, domain specialization |
-| [#894](https://github.com/CambrianTech/continuum/issues/894) | post-launch | Vision-Qwen3.5 variants per device tier — M5 default 4B-vision, MBA smaller, 3090+ larger |
-| [#895](https://github.com/CambrianTech/continuum/issues/895) | PR891 follow-up | Live multi-persona concurrency benchmark — 3-5 personas on M5, regression-gate for the scheduler |
-
-### What PR891 delivers toward this goal
-
-- **Continuous-batching scheduler** — shared Context, `n_seq_max` sequences (enables 3-5 concurrent persona streams from ONE model instance, KV pool shared not duplicated).
-- **Response-cap hard gate REMOVED** — personas can keep engaging in live chat without arbitrary silencing.
-- **Acceleration architecture committed** (no CPU fallback; UDP sidecar fallback designed for any case where a subsystem can't containerize) — guarantees every sensory subsystem stays GPU-close.
-- **Vulkan-in-container** for Mac Carl → Qwen3.5 at ~80% native Metal in a container, keeping Mac Carl install low-friction.
-- **Un-cheat sensory parity** (Phase 1 of RESTORE-FULL-PARITY-PLAN): whisper.cpp vendor, remove SKIP_STT/SKIP_TTS hatches, LiveKit default-features, avatars ship. Lands the sensory stack that makes "live chat" actually live.

-## Phase 2: Live Call Quality & Resource Management
-
-> The 3D video calls work but leak memory, have high latency, and break offline.

-| [#331](https://github.com/CambrianTech/continuum/issues/331) | **Live call quality** ⚠️ CRITICAL | TODO | Avatar vertex corruption — most personas show shredded/exploded geometry in live view. 8 VRM models for 15 personas = overflow models garbled. Also: memory leaks, latency, simultaneous speech. |

-| [#582](https://github.com/CambrianTech/continuum/issues/582) | **Native multimodal pipeline** ⚠️ HIGH | TODO | Direct audio/vision for capable models (one hop, <2s), bridge only for text-only. Three parallel streams: LISTEN + THINK + SPEAK. Fundamental architecture fix. |
-| [#339](https://github.com/CambrianTech/continuum/issues/339) | **Live mode latency: 30s STT delay** | SUPERSEDED by #582 | STT→LLM→TTS pipeline too slow. #582 eliminates the pipeline entirely for multimodal models. |
-| ~~[#340](https://github.com/CambrianTech/continuum/issues/340)~~ | **AIs talk over each other** | DONE | Merged into #331. |
-| ~~[#318](https://github.com/CambrianTech/continuum/issues/318)~~ | **Avatar models eating 26GB** | DONE | Cleaned up — 8 CC0 VRoid models only. |
-| [#322](https://github.com/CambrianTech/continuum/issues/322) | **More CC0 avatar models** ⚠️ CRITICAL | TODO | Only 8 models for 15 personas. Overflow causes vertex corruption. Need 15+ working VRM 0.x models. |

-
-| [#797](https://github.com/CambrianTech/continuum/issues/797) | **LiveKit + livekit-bridge Docker validation** | TODO | Validate three-binary split works in Docker. Bridge socket, audio pipeline, browser call join. |
-| [#799](https://github.com/CambrianTech/continuum/issues/799) | **Qwen3.5 native audio — skip VAD→STT→LLM→TTS** | TODO | Audio-native models bypass the entire pipeline. Router exists in `live/audio/router.rs`. Needs Qwen3.5-Omni GGUF. |
-| [#800](https://github.com/CambrianTech/continuum/issues/800) | **Custom forged STT model** | TODO | Whisper-equivalent trained on technical vocabulary. Publish as `continuum-ai/whisper-forged`. |
-| [#801](https://github.com/CambrianTech/continuum/issues/801) | **Custom TTS voices per persona** | TODO | Persona-specific voice synthesis via Pocket-TTS cloning + fine-tuning. |
-
-**Done when**: Avatar geometry works for ALL personas (no vertex corruption). Live call closes → memory baseline in 30s. Latency under 5s. All personas can see. Grid telemetry visible. Native audio models skip STT/TTS chain.

-## Phase 3: Tool Calling & Local Model Reliability
-
-> THE blocker for local-first AI. Personas can't reliably call tools with local models.
-

-| [#325](https://github.com/CambrianTech/continuum/issues/325) | **Ship 14B model, research 32B QAT** | TODO | 14B at Q5_K for MacBook Air. 32B QAT for 32GB machines. |
-| [#371](https://github.com/CambrianTech/continuum/issues/371) | **Per-task model routing** | DONE (PR #401) | Fixed hasTools false for XML providers — local personas now upgrade to cloud for tool use. |
-| [#343](https://github.com/CambrianTech/continuum/issues/343) | **Native multimodal** | TODO | Skip STT/TTS for models that handle audio/images directly. |
-| [#342](https://github.com/CambrianTech/continuum/issues/342) | **Vision feedback** | REOPENED | Pipes exist but full loop (see→fix→verify) not proven. Needs #493 + #480. |
-| [#341](https://github.com/CambrianTech/continuum/issues/341) | **API cost budgeting** | PARTIAL (PR #405) | Cost tracking fixed (used wrong provider). `ai/cost` command works. Budget limits still TODO. |
-| [#413](https://github.com/CambrianTech/continuum/issues/413) | **Sentinel logs: list available streams** | DONE (PR #421) | Error messages now list available streams. Found by AI team. |
-| [#417](https://github.com/CambrianTech/continuum/issues/417) | **Evaluate Qwen3.5-35B-A3B** | TODO | Opus reasoning distilled, 3B active MoE. Could replace Llama-3.2-3B as local model. |
-
-**Done when**: Local model reliably calls tools. Parser handles all model families. Per-task routing picks best model. Cost tracked.

-## Phase 4: End-to-End Development Orchestration
-
-> From "AI that chats" to "AI that ships code."
-
-| # | Issue | Status | What |
-|---|-------|--------|------|
-| [#326](https://github.com/CambrianTech/continuum/issues/326) | **E2E dev orchestration** | TODO | Sentinel templates → auto-trigger → PR workflow → chat bridge. |
-| [#370](https://github.com/CambrianTech/continuum/issues/370) | **Coding pipeline never proven** | PARTIAL (PR #407) | sentinel/coding-agent works e2e. Persona→chat→code trigger needs proof. |
-| [#411](https://github.com/CambrianTech/continuum/issues/411) | **Self-improving system** | TODO | Personas autonomously propose → code → test → PR. The endgame. |
-| [#415](https://github.com/CambrianTech/continuum/issues/415) | **Dispatch classifier too trigger-happy** | DONE (PR #419) | Tightened patterns + technical context gate. |
-| [#416](https://github.com/CambrianTech/continuum/issues/416) | **sentinel/resume rejects BudgetExhausted** | DONE (PR #420) | Budget exhaustion now sets correct resumable status. |
-
-**Previously completed:**
-- 3 sentinel dev templates (build-feature, fix-bug, code-review) — DONE
-- TemplateRegistry — DONE
-- SentinelChatBridge — DONE
-- SentinelDispatchDecider — DONE
-
-**Remaining:**
-- [ ] 2 more templates (create-pr, refactor)
-- [ ] PR workflow commands (push, create, review, status)
-- [ ] Template parameter extraction from chat context
-- [ ] Prove the full loop: chat request → sentinel → code → tests → commit → PR
-
-**Done when**: Someone says "add rate limiting to the login endpoint" in chat → persona spawns sentinel → code written → tests pass → PR created. Proven, not theoretical.

-## Phase 5: Academy — Full Training Loop
-
-> The README promises personas get smarter every day. Prove it.
-
-| # | Issue | Status | What |

-| [#377](https://github.com/CambrianTech/continuum/issues/377) | **Full academy session E2E** | TODO | All challenges → failures → LoRA trained → re-exam → measurable improvement. Never completed. |
-| [#369](https://github.com/CambrianTech/continuum/issues/369) | **RealClassEval trash with local models** | REOPENED | Solved by compaction + training, not API keys. Open until local model passes. |
-| [#374](https://github.com/CambrianTech/continuum/issues/374) | **Teacher needs cloud API** | REOPENED | Compacted 35B MoE IS the teacher. Needs #492 first. |

-| [#359](https://github.com/CambrianTech/continuum/issues/359) | **Training env auto-bootstrap** | TODO | Any Grid node can train — zero manual intervention. |
-
-**The critical path:**
-```
-#374 (local teacher) → #377 (full session) → #369 (quality baseline)
-    → #344 (ship tuned model) → #384 (team training)
-```
+- Mac/Windows report generated from structured metrics, not copied terminal log.
+- CPU peg, CPU layer fallback, missing tok/s, and memory growth become failed

+- hand-assembled performance report scripts that scrape random console text
 
-## Phase 6: Genome & Adapter Ecosystem
+### Lane D: CBAR Persona Runtime Frame
 
-> Personas carry skills in their genome. Skills page in/out. Skills are shared globally.
+**Problem**: persona inbox/RAG/scheduling behavior can flood inference by
+treating events too literally. The runtime needs a CBAR-like turn frame:
+immutable input, lazy derived outputs, coalesced work, and independent nodes.
 
-| # | Issue | Status | What |
-|---|-------|--------|------|
-| [#382](https://github.com/CambrianTech/continuum/issues/382) | **Genome paging not wired** | TODO | activateSkill/evictLRU exists but not connected to persona loop or GPU governor. |

+**Design**:
 
-**Done when**: Persona faces a Python task → genome pages in python-expertise adapter → processes task → publishes adapter to HuggingFace → another instance discovers and pulls it.
+- `PersonaTurnFrame` wraps room/user/persona signal state for a bounded turn.
+- Lazy outputs include consolidated inbox chunk, RAG context, media summary,
+  priority score, tool relevance, model requirement, and response prompt.
+- Nodes pull what they need and pay only for what they request.
+- Inbox consolidation is FIFO-preserving but chunked: many room events can
+  produce one planned turn instead of one inference per event.
+- The frame is the Rust-owned e2e cognition boundary: chat, live, coding,
+  game/VR, and AIRC hosts all submit generic inbox/activity items and receive
+  typed turn outputs without Node owning truth-layer cognition state.
+- Production turns must emit replayable records containing inbox inputs, frame
+  decisions, RAG source hashes, memory/hippocampus selections, prompt assembly,
+  resource leases, model/backend choice, and output metadata. Tests may use
+  fixtures, but the fixture format must come from real prod records.

+1. `persona-turn-frame`: frame/trait/pipeline skeleton with lazy outputs.
+2. `inbox-coalescing`: chunk/buffer room events and prove one turn per window.
+3. `rag-frame-output`: RAG composition becomes a lazy frame output with trace.
+4. `prg-shim-shrink`: TS PRG becomes a thin command shim or deletes.
 
-**Done when**: Leave the system running overnight → come back to find personas have consolidated memories, audited skills, searched HuggingFace for useful adapters, and initiated peer learning sessions. Personas know your calendar. External communication gated by epistemic verification. Without any human prompt.
+**TDD**:
 
----
+- Rust tests for lazy output computes once across multiple consumers.
+- Inbox test: N events within window -> one consolidated turn plan.
+- Replay test: fixture reproduces prompt/RAG/media from frame outputs.
+- Prod-record replay test loads a captured `PersonaTurnFrame` record without

-## Phase 8: Distillation & Training Flywheel
+**VDD**:
 
-> The competitive moat: every task makes the next task better.
+- Chat smoke records fewer inference calls than incoming events.
+- First response improves or stays flat while CPU/RSS do not climb.
+- Live/prod capture from at least one real chat turn can be replayed offline and

+### Lane E: Pressure Broker And Paging Gate
 
----
+**Problem**: model, context, LoRA, media, and backend resources are still too
+independent. The correct controller must admit, page, evict, or defer across
+all resource types under one policy.
 
-## Phase 9: Codebase Intelligence
+**Design**:
 
-> Know what you're changing before you change it.
+- `PressureBroker` owns admission for model weights, mmproj/mtmd contexts, KV
+  cache, LoRA adapters, embedding cache, WebRTC/media buffers, and render
+  textures.
+- Resource pools expose typed cost, residency, last-use, priority, and eviction
+  hooks.
+- Unsafe requests return `Backpressured`, `Unavailable`, or `Deferred` with an
+  explanation. They do not allocate and hope.

-| Node | GPU | VRAM | RAM | Role | Status |
-|------|-----|------|-----|------|--------|
-| Joel 5090 tower | RTX 5090 | 32GB | 32GB | Primary forge, heavy training | Online (WSL2) |
-| Joel 1080Ti box | 3x GTX 1080Ti | 33GB total | 128GB | Distributed inference, CPU pruning, GGUF conversion | **OFFLINE — blocked on install.sh** |
-| Joel 970 box | GTX 970 | 4GB | ? | Light inference, testing | **OFFLINE** |
-| Joel MacBook Pro | M1 Pro | 32GB unified | 32GB | MLX inference, testing, dev | Online |
-| Joel MacBook Air | M1 | 8GB unified | 8GB | iPhone-class testing (same RAM budget) | Available |
-| Toby 3090 | RTX 3090 | 24GB | ? | Secondary forge, inference | **OFFLINE — blocked on install.sh** (PR #535) |
-| Toby 5050 | RTX 5050 | 8GB | ? | Light inference, edge testing | **OFFLINE** |
-
-**The 1080Ti box alone unblocks**: parallel GGUF conversion (128GB RAM), distributed inference (3 GPUs), CPU expert pruning without blocking the 5090 forge. Getting `install.sh` working is THE grid priority.
-
-| [#798](https://github.com/CambrianTech/continuum/issues/798) | **Route inference through grid to GPU nodes** | TODO | When BigMama online, route `ai/generate`, STT, TTS to 5090 instead of laptop. Grid router exists, needs wiring to AI provider. |
-| [#806](https://github.com/CambrianTech/continuum/issues/806) | **Tailscale ghost nodes on restart** | DONE (PR #809) | State volume persists identity. `TS_HOSTNAME` defaults to `{hostname}-grid`. No more orphaned devices. |
-| [#807](https://github.com/CambrianTech/continuum/issues/807) | **Auto grid profile when Tailscale configured** | TODO | `setup.sh` detects Tailscale → enables grid automatically. No manual `.env.grid` copy or `--profile grid`. |
-| [#808](https://github.com/CambrianTech/continuum/issues/808) | **Grid config provisioning** ⚠️ HIGH | TODO | `grid/provision` syncs config.env from primary node. No manual `scp`. One Tailscale key is the only manual step. |
-| [#811](https://github.com/CambrianTech/continuum/issues/811) | **Docker node shows 127.0.0.1 / no GPU** | PR #813 | Grid Overview fetches grid/status for real Tailscale IP and GPU capabilities. |
-| [#814](https://github.com/CambrianTech/continuum/issues/814) | **Self-healing — auto-wake and restart downed nodes** | TODO | Foreman detects offline → WoL via Tailscale → SSH restart. Grid is the immune system. |
-| [#815](https://github.com/CambrianTech/continuum/issues/815) | **In-browser terminal for node management** | TODO | AWS-style console. SSH button → terminal widget → Tailscale IP. Wake/restart/rebuild/logs from grid page. |
-
-**Done when**: `install.sh` works on the 1080Ti box and Toby's 3090. Grid ping succeeds across Tailscale. A training job started on the 5090 checkpoints and resumes on the 3090 when the 5090 reboots. Ares detects a game launching and yields GPU. GGUF conversion runs on the 1080Ti box while 5090 forges. Inference routes to BigMama when laptop is on Tailscale. Config propagates automatically to new nodes via `grid/provision`. Downed nodes auto-revive. Full node management from browser.

-## Phase 11: Docker — Full-Stack Containerization (PR #740)
-
-> `docker compose up` — Tailscale handles TLS, containers serve HTTP. Real HTTPS, no warnings.
-
-| # | Issue | Status | What |
-|---|-------|--------|------|
-| [#737](https://github.com/CambrianTech/continuum/issues/737) | **Docker architecture** | WORKING | docker-compose.yml: tailscale, postgres, continuum-core, node-server, widget-server, livekit, model-init, forge-worker, inference. All containers healthy on BigMama. |
-| — | **Tailscale sidecar TLS** | DONE | Tailscale container joins tailnet, provisions Let's Encrypt certs, reverse-proxies HTTPS/WSS to plain HTTP containers via TS_SERVE_CONFIG. No Caddy, no self-signed, no manual certs. Two prereqs: enable HTTPS certs in Tailscale DNS settings + generate auth key. |
-| — | **ONNX Runtime in Docker** | DONE | ONNX Runtime 1.24.4 installed in continuum-core image. ORT_DYLIB_PATH env var set. Silero VAD + Piper TTS work (persona hearing + speech). |
-| — | **Postgres in Docker** | DONE | SecretManager no longer overwrites Docker env vars with config.env values. DATABASE_URL from compose takes precedence. |
-| — | **WS localhost fallback bug** | DONE | TransportConfig.ts used `ws://localhost` for non-HTTPS pages. Now always uses `window.location.hostname` in browser. Vite bundle rebuilt. |
-| — | **IPC crash without Rust core** | DONE (PR #740) | Node-server no longer crashes if continuum-core socket missing. |
-| — | **Auto-seed on first run** | PARTIAL | docker-entrypoint.ts detects empty DB, runs seed-continuum.ts. Rooms seed (11/12). Personas fail (IPC drops under heavy seeding). Needs resilient seeding with retry. |
-| — | **ARM64 Docker: WebRTC** | DEFERRED | LiveKit runs as separate container. Rust binary built without livekit-webrtc feature (`--no-default-features`). |
-| — | **Persona seeding in Docker** | TODO | AI users not created. Seed script IPC connections fail under heavy load. Need: (a) batch seeding with delays between records, or (b) direct SQL seed for Docker. |
-| — | **Voice/avatar models** | TODO | model-init container exists but voice-models volume not populated on BigMama. Need `docker compose run model-init`. |
-| — | **CI multi-arch images** | TODO | GHCR publishing workflow exists but not tested on this branch. |
-| — | **WSS port routing** | DONE (PR #809) | Browser WebSocket now connects to configured WS_PORT (9001), not page port (443). Fixes Tailscale reverse proxy. |
-| — | **Port conflict Tailscale vs node-server** | DONE (PR #809) | Removed duplicate 9002:9001 host mapping from Tailscale. Tailscale serve proxies internally. |
-| — | **GHCR images rebuilt** | DONE | All 5 images rebuilt on BigMama and pushed to GHCR (2026-04-06). |
-| [#796](https://github.com/CambrianTech/continuum/issues/796) | **Docker E2E with live mode + grid** | PARTIAL | Chat works, AIs respond, HTTPS via Tailscale works, factory shows leaderboard. Remaining: live calls, grid discovery from browser. |
-
-**Prereqs** (one-time, per tailnet):
-1. Tailscale installed + HTTPS certificates enabled in DNS settings
-2. Auth key generated (reusable + ephemeral) → stored in `.env` as `TS_AUTHKEY`
-
-**Done when**: `docker compose up` on a fresh machine with Tailscale brings up the full system with all personas, avatars, and voice models. Accessible at `https://<hostname>.ts.net`.

-## Phase 12: Factory — Model Forge Production Line
-
-> Nature: forge base models. Nurture: academy trains personas. Factory is nature. The factory is the product's front door — the widget that brings people in and the grid that keeps them.
-
-The factory forges, benchmarks, and publishes base models for every device tier. HuggingFace is the app store — we provide the factory, community provides hardware. Models forged through our pipeline have known provenance enabling re-forging (the moat). Recipes are shareable end-to-end templates that encode the entire forge process.
-
-**Strategy**: HF leaderboards for benchmarks (don't reinvent). Right-panel sidebar for our leaderboard/stats. Competitive spirit drives adoption. Recipes are the apps, factory is the store, grid is the compute.

-#497 (compaction + paging) → #433 + #439 (MoE paging/surgery)
-    → ANY model on ANY hardware
-```
+**Problem**: migration intent is not enough. The repo needs a mechanical gate
+that prevents new verb-shaped TS cognition and forces deletion as Rust lands.
 
-**Done when**: A persona on a MacBook Air with zero API keys receives "make the chat input rounded," takes a screenshot, edits the CSS, rebuilds, takes another screenshot, and confirms the fix. All inference local. Model published to HuggingFace.
+**Design**:
 
----
+- CI/check script computes TS cognition line count for touched cognition PRs.
+- New `.ts` files under persona cognition directories fail unless allowlisted as
+  ORM noun, generated schema, UI, or thin shim.
+- Forbidden strings such as deprecated provider names or fallback comments are
+  blocked in runtime code and docs that are not migration notes.
 
-## The Narrative
+**Owned files/modules**:
 
-**Phase 0** removes the embarrassments — things that break the first-run experience.
+- test/ratchet scripts
+- CI/pre-push hooks
+- `src/tests/unit/shared-node-boundary.test.ts`
+- docs describing exceptions
 
-**Phase 1** makes the codebase worthy of public scrutiny. Contributors will copy these patterns forever.
+**PR sequence**:
 
-**Phase 2** makes the live video calls — the most visually impressive feature — actually reliable. No leaks, low latency, works offline.
+1. `persona-ts-ratchet-script`: local script with clear failure output.
+2. `persona-ts-ratchet-ci`: CI/pre-push enforcement for touched cognition PRs.
+3. `forbidden-provider-scan`: remove and block obsolete provider/runtime names.
 
-**Phase 3** solves THE local model blocker. Without reliable tool calling, personas are chat decorations. With it, they're functional teammates.
+**TDD**:
 
-**Phase 4** proves personas can CREATE things, not just discuss them. Code → tests → PR, end-to-end.
+- fixtures for allowed generated/UI/noun TS and forbidden verb TS.
+- scan test proves obsolete provider names cannot re-enter runtime code.
 
-**Phase 5** proves personas get SMARTER over time. The full Academy loop, measured.
+**VDD**:
 
-**Phase 6** makes trained skills portable and composable. The genome ecosystem.
+- each cognition PR reports TS lines before/after and Rust test coverage.
 
-**Phase 7** makes personas autonomous — they initiate work, not just respond to it.
+**Deletion targets**:
 
-**Phase 8** closes the flywheel — every task improves the next task. The competitive moat.
+- stale comments, tombstones, fallback branches, and obsolete provider mentions
+- any TS cognition file replaced by a Rust module
 
-**Phase 9** gives personas deep codebase understanding. Know before you change.
+## Issue-Driven Workstreams
 
-**Phase 10** distributes everything across a mesh of commodity hardware. **Ares** — the Grid Governor — commands resources, detects when users need their machines, and keeps the mesh alive as nodes come and go. First experiment: 5090 + 3090 + 1080 Ti. The Cell architecture realized.
+### 0. Canary Discipline And Collaboration
 
-**Phase 11** is THE unlock — plasticity compaction + MoE paging + vision + Academy training = personas that SEE and BUILD their own UI, on a MacBook, with zero API keys. Every download of a compacted model. Every upload of a trained adapter to HuggingFace. Every persona that designs a widget, trains a model, improves itself. The flywheel.
+**Goal**: stop parallel agents from diverging. Every agent should know the issue, branch, PR, validation command, and current blocker.

+| PR #1035 | current canary -> main promotion PR | Keep rebased; promote only after canary has real chat/local-model validation plus relevant platform smoke |

+| CambrianTech/airc#559 | public knock, approved room handoff, shared sprint queue | AIRC canary has knock and encrypted approve handoff; Continuum must consume the workflow through `.airc/` and persona/agent integration |

+| CambrianTech/airc#563 | AIRC message/file substrate | Needed before Carl/browser chat smoke can stop using JTAG chat commands |
+
+Rules:
+
+- Implementation starts from an issue. If no issue exists, file it before coding.
+- PR body must include: issue link, canary target, validation commands, platform coverage, and what was not tested.
+- Agents coordinate on AIRC, but the durable truth is issue + PR comments.
+- `main` promotion only happens after canary has been exercised by at least one real UI path and one non-UI/Rust path relevant to the changes.
+- Open PRs are triaged every session before new feature work. Each gets one of four states: `merge-after-green`, `needs-rebase`, `convert-to-issue`, or `close-stale`.
+- A PR older than 48 hours without a concrete blocker is presumed stale until proven otherwise.
+- If a PR is correct but incomplete, finish and merge it to canary; do not recreate the same work on a new branch.
+
+### 0A. AIRC As The Development Substrate
+
+**Goal**: Continuum should be able to develop itself through a shared grid of
+agents, personas, local models, and humans. AIRC owns the coordination substrate;
+Continuum exposes reliable generated commands and consumes AIRC as an
+integration layer.
+
+The operating model:
+
+- AIRC remains available even when Continuum is down, rebuilding, wedged, or
+  being restarted. It is the continuity layer for work state, handoffs, and
+  recovery.
+- GitHub issues and PRs are the durable work cards. AIRC provides the concise
+  room digest, presence, nudges, approval, and peer-to-peer coordination around
+  those cards.
+- One GitHub account may run many agents. Assignment and presence must use AIRC
+  peer/session identity, nick, role, bio, and whois data rather than assuming
+  one GitHub login equals one worker.
+- Agents should not need a human to ask what to do. An approved agent joins,
+  receives the room rules and current queue digest, claims or reviews a card,
+  posts evidence, and releases or completes the card.
+- `airc nudge` / queue nudges must be peer-to-peer, not manager-only. Any
+  online approved peer can poke idle peers to poll the queue, report blockers,
+  or pick up stale work.
+- Cloud models, local models, Continuum personas, OpenClaw, Hermes, and future
+  grid workers all plug in as workers if they can speak AIRC and execute the
+  relevant Continuum command surface.
+- This is intentionally an OpenClaw-lite/Hermes-lite development framework,
+  not a replacement for those projects. AIRC supplies the small, durable
+  collaboration/control plane: rooms, identity, queue cards, nudge/stale
+  detection, PR proof, and handoff. Continuum supplies the local runtime,
+  cognition, Sentinels, generated commands, grid execution, and product UI.
+- The alpha target is useful even with no web interface running. A developer
+  should be able to install AIRC, join the project room, run Continuum's Rust
+  backend/Sentinel worker surface, and let approved agents coordinate work
+  across local and grid machines without Node being required for the core
+  worker loop.
+- Continuum commands used by these workers must be generated/template-first.
+  Manual command scaffolds break the self-development loop because agents need
+  one predictable command contract.
+- JTAG chat commands are compatibility plumbing. The target is AIRC transcript
+  plus file/attachment APIs for live chat, scrollback, cursors, receipts, and
+  replay. Continuum should consume compact events/pointers and project only
+  bounded durable state.
+
+Near-term Continuum tasks:
+
+1. Land PR #1110 so this repo advertises its AIRC front door, rules, and queue
+   expectations from `.airc/`.
+2. Wire Continuum personas into AIRC rooms as first-class peers for issue/PR
+   digest, claim/release/done, and nudge handling.
+3. Expose generated Continuum commands that let agents run bounded smoke tests,
+   image preflights, install checks, and forge/factory preflights without
+   needing bespoke shell knowledge.
+4. Move the core agent worker path toward Rust-only execution: queue polling,
+   Sentinel dispatch, generated command execution, and proof emission must have
+   a no-Node path so Continuum can serve agents while the browser/UI stack is
+   down.
+5. Validate the pilot by having at least one external peer join through knock,
+   receive approval, claim a GitHub-backed work card, post validation evidence,
+   and hand off through AIRC.
+
+### 1. First-Run And Install Stability
+
+**Goal**: a new user does not hit a silent or half-working install.
+
+| Issue | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #1006 WSL2 cannot reach raw.githubusercontent.com | P0 | install must detect network/bootstrap failure early and print a concrete fix | Windows fresh install log shows failure in <30s with remedy |
+| #1007 Windows rustc ICE compiling continuum-core | P0 | do not make first-run depend on a fragile local Rust build when a published binary/image can be used | Windows install reaches runnable app without compiling core locally |
+| #1008 core socket owned by root container | P0 | fix UID/GID and socket volume ownership; host `jtag` must connect | host `jtag ping` succeeds against container core |
+| #980 Carl validator QA bugs | P0 | break into child issues if still bundled | each child has a canary PR or is closed as stale |
+| #983 Vulkan deferred model download | P0 | download/prewarm with progress during install or show explicit first-chat loading state | first Vulkan chat never sits silent during multi-GB download |
+| #770 fresh install E2E | P0 | make this the release gate, not a one-off QA task | Mac + Windows reinstall logs attached to canary validation |
+
+Implementation posture:
+
+- Prefer published Rust artifacts or minimal service images over compiling everything during first-run.
+- If build is unavoidable, make it explicit and resumable.
+- Install health must distinguish: network unavailable, Docker unavailable, GPU unavailable, model unavailable, Rust core unavailable, UI unavailable.
+
+### 1A. Config, Secrets, And Grid Propagation
+
+**Goal**: one authoritative config path per node, explicit encrypted propagation across trusted grid nodes, and no false "configured" state from empty placeholders.
+
+| Issue | Priority | Direction | Test gate |
+|---|---:|---|---|
+| file: config single-source issue | P0 | `SecretManager` and Rust `secrets.rs` must treat only non-empty values as configured and must lazy-load `$HOME/.continuum/config.env` before any provider check | provider status shows cloud unavailable for empty placeholders; local chat still works |
+| [#1097](https://github.com/CambrianTech/continuum/issues/1097) API-key merge commands | P0 | extend the existing `ai/key/*` command surface for encrypted config sharing over trusted grid/Tailscale nodes; no loose file copying and no browser exposure | two-node test shares selected keys, decrypts only on trusted target, and never logs values |
+| [#1098](https://github.com/CambrianTech/continuum/issues/1098) routed command program substrate | P0 | consolidate bounded multi-command execution on top of `grid/send`, `GridInterceptor`, and `grid/route` so secrets and forge use the same path | one local-grid test runs a redacted `ai/key/*` program; one forge preflight routes through the same envelope |
+| #860 config.env as directory | P1 | keep setup file/dir creation idempotent and typed | setup test catches file-vs-dir mismatch |
+
+Implementation status:
+
+- Shared `ai/key` base types now exist for provider identity, sync intent,
+  target nodes, dry-run, synced state, and merge-plan id.
+- Existing `ai/key/save`, `ai/key/remove`, and `ai/key/test` shared types
+  inherit the base. Runtime sync behavior is intentionally not claimed until the
+  routed reconciliation path exists.
+- `ai/key/status` is generated from `tools/generator/specs/ai-key-status.json`
+  and returns only redacted provider/key/source/configured/fingerprint metadata.
+- `grid/send` is the explicit routed command envelope; `GridInterceptor` is the
+  transparent `Commands.execute()` remote path; `grid/route` is the dry-run
+  routing/debug primitive.
+
+Command shape:
+
+- Existing `ai/key/save`: write one key through `SecretManager` to `$HOME/.continuum/config.env` or the platform vault; command echo and logs must redact values.
+- Existing `ai/key/remove`: remove one key through `SecretManager`.
+- Existing `ai/key/test`: validate a candidate or stored provider key.
+- Existing `ai/providers/status`: provider-facing availability view.
+- `ai/key/status`: list configured key names, source path, empty placeholders, fingerprints, and provider health without values.
+- `ai/key/diff`: compare redacted key revisions across selected target nodes and produce a merge plan without values.
+- `ai/key/apply-merge`: apply an approved merge plan through `SecretManager`; conflicts require owner/persona approval and never auto-overwrite a newer local key.
+
+Rules:
+
+- Empty placeholders such as `DEEPSEEK_API_KEY=` are documentation, not availability.
+- Local mode must work with zero API keys.
+- Cloud personas are eligible only when their required key is non-empty and the provider health check is not expired/failed.
+- Config sharing is an owner/trusted-node command. It should use grid identity plus transport encryption, then persist through `SecretManager` so all runtimes see one source.
+- Remote/grid execution is command routing context, not a namespace. The capability name stays stable while target environment changes.
+- Fresh install and Carl smoke must pass with public model downloads and no `HF_TOKEN`; token-dependent private/gated/factory upload paths are optional later setup.
+
+### 2. GPU Runtime Stability
+
+**Goal**: GPU resource failures degrade or recover; they do not brick the session.
+
+| Issue | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #1048 mmproj/mtmd init mutex | P0 | one mtmd-capable backend may enter Metal pipeline/mmproj init at a time | Rust concurrency test: parallel vision/audio backend init serializes and all callers receive a sane result |
+| #1050 backend recovery state machine | P0 | represent backend as `Healthy`, `Initializing`, `Recovering`, `Dead`, `Unavailable`; recover/drop/recreate on OOM/dead backend | Rust test with injected backend failure recovers or reports `Unavailable`, never hangs |
+| #960 Mac Metal throughput 5-7 tok/s | P0 | measure and fix actual GPU path; do not route through slow CPU-shaped fallback | benchmark shows expected Metal path and records tok/s |
+| #964 ONNX Runtime CPU spike | P0 | enforce Metal/GPU provider selection for fastembed/TTS/STT/vision bridge or fail loud | test/log proves provider is Metal/GPU; CPU fallback is explicit |
+| #948 DMR concurrency failure | P1 | add bounded request scheduling/backpressure around DMR | 4+ persona concurrency test passes without reqwest cascade |
+| #915 Kokoro ONNX deadlock | P1 | isolate session creation and apply GPU provider lifecycle rules | regression test for TTS startup no deadlock |
+| #918 multimodal-native worker | P2 | after lifecycle is safe, collapse voice chain latency | live voice turn benchmark |
+
+Rust targets:
+
+- `core/continuum-core/src/inference/`
+- `core/llama/src/mtmd.rs`
+- `core/continuum-core/src/gpu/`
+- `core/continuum-core/src/live/audio/`
+
+Do not fix these in TypeScript. TS may display state and call commands; it must not own backend lifecycle.
+
+### 3. Rust Persona Runtime And Cognition
+
+**Goal**: personas can run, replay, and be embedded without Node acting as the brain.
+
+| Issue / doc | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #969 migrate tool agent loop to Rust | P0 | move persona/tool loop behavior out of TS | net-negative TS cognition lines and Rust replay test |
+| #909 local persona tool execution | P0 | wire local DMR/Candle tool execution through Rust path | local persona can call a tool without cloud path |
+| #958 DMR repetition penalty / echo | P0 | fix generation config at adapter layer | replay/conversation test proves no verbatim echo loop |
+| #837 raw tool-call XML leak | P1 | output rendering and model post-processing both need tests | fixture with tool markup renders/filters correctly |
+| #970 missing image marker | P1 | ensure media markers are role/content correct in Rust prompt assembly | vision replay fixture includes media marker |
+| docs/architecture/PERSONA-AS-RUST-LIBRARY-PLAN.md | P0 reference | keep as detailed architecture, but alpha doc owns sequencing | cargo tests run without Node |
+| docs/architecture/PERSONA-COGNITION-RUST-MIGRATION.md | P0 reference | enforce "Rust = verbs, TS = nouns/shims" | PRs touching cognition show TS line reduction |
+
+Near-term PR sequence:
+
+1. **PR: Rust persona trace/recorder validation**
+   - issue: file/link if not already present
+   - scope: Rust fixture capture and replay for a chat turn
+   - tests: `cargo test --package continuum-core persona`
+2. **PR: Rust tool loop migration**
+   - issue: #969
+   - scope: shrink TS tool-agent loop to a shim
+   - tests: Rust tool loop unit/integration test; net-negative TS cognition lines
+3. **PR: local persona tool execution**
+   - issue: #909
+   - scope: local model path can execute tools without cloud-only assumptions
+   - tests: local persona tool-call replay; no browser required
+
+### 4. Unified Paging And Pressure Control
+
+**Goal**: support many personas and modalities by paging resources coherently instead of over-allocating and hoping.
+
+| Issue / doc | Priority | Direction | Test gate |
+|---|---:|---|---|
+| docs/architecture/UNIFIED-PAGING.md | P0 reference | `PagedResourcePool` is the primitive; migrate consumers one at a time | pool tests plus consumer-specific tests |
+| docs/architecture/PERSONA-CONTEXT-PAGING.md | P0 reference | KV/persona context paging policy | tests prove bounded memory with multiple personas |
+| #1049 PressureBroker admission gate | P0 | broker must deny unsafe allocations, not just observe them | admission test refuses second unsafe mtmd/backend creation |
+| #1051 MtmdContext pooling | P0 | reuse multimodal context instead of fresh multi-GB allocation per image/frame | replay test avoids repeated context allocation |
+| #945 data/query memory leak | P0 | apply resource attribution and leak tests | load test stays within memory envelope |
+| #944 embedding loop/cache misses | P1 | migrate embedding cache to shared paging primitive | repeated index pass has cache hits and bounded memory |
+| #911 16GB MacBook Air | P1 | define reduced alpha profile with strict budgets | 16GB profile starts and reports disabled features honestly |
+
+Model selection contract:
+
+- Callers request capabilities, not model IDs.
+- Discovery and admission are separate: discovery builds the catalog of model
+  artifacts, modalities, context windows, templates, quantizations, and backend
+  requirements; admission chooses the best viable candidate for the current
+  machine state and request.
+- The catalog is a curated whitelist, not arbitrary Hugging Face passthrough.
+  Candidate discovery may crawl/search HF offline or through foundry commands,
+  but runtime selection only admits vetted rows with known templates, license,
+  backend compatibility, memory estimates, modality metadata, and forge status.
+- Foundry output flows back into the same registry: `candidate` -> `vetted` ->
+  `forged` -> `published`, with Sentinel/foundry jobs updating metadata rather
+  than TS code hardcoding new model names.
+- Provider identity must be typed. Runtime local chat is `LocalRuntime`
+  (llama.cpp/Qwen through our adapter stack), cloud providers are explicit
+  external identities, and Candle is not an inference provider for persona chat.
+  Export this with `ts-rs` so TS seed/config/user paths cannot invent free-form
+  provider strings.
+- Request fields should be typed: `taskKind`, `minIntelligence`, `modalities`, `toolSupport`, `minContextTokens`, `latencyClass`, `qualityClass`, `memoryBudget`, `gpuRequired`, `familyAllowlist`, `familyPreference`, and `explicitOverride`.
+- Constraint syntax should feel like semver where it helps: exact pins for repro, `>=` for minimum intelligence/capability, `~qwen3.5` for near-family preference, ranges for context/latency/memory, and hard allow/deny lists for safety.
+- Rust registry/admission returns the selected provider/model/artifact plus explanation: why selected, why alternatives were rejected, projected VRAM/RAM/KV/LoRA footprint, and whether the choice is degraded.
+- Persona seed stores intent (`local-default`, `vision-default`, future typed capability refs), not hardcoded model strings.
+- TS may display selection state; it must not invent fallback models.
+
+Implementation order:
+
+1. PressureBroker admission gate.
+2. Backend/mmproj lifecycle integration.
+3. First consumer migration: embedding cache or mtmd context pool.
+4. KV/persona context policy.
+5. LoRA adapter paging.
+
+### 5. Docker Modularization
+
+**Goal**: Docker should isolate services and make failures obvious; it must not become a bulk mess that hides Rust/Node/UI problems.
+
+| Issue | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #892 CUDA Docker path bypasses our substrate | P0 | GPU profile must run Continuum runtime or explicitly documented external service, not orphaned upstream server | GPU compose path exercises our adapter/router health |
+| #955 floating CUDA image tag | P0 | pin digest or controlled version | CI verifies pinned image |
+| #834 / #776 image size | P1 | split build/runtime layers; remove unused Node/vendor bulk from runtime images | image size trend published in PR |
+| #796 Docker compose E2E live mode/grid | P1 | profile-based compose tests, not one giant default | compose profile tests pass independently |
+| #908 Windows npm start should route through docker compose | P1 | Windows dev path should use the supported Docker/WSL path | Windows smoke reaches GPU-backed inference |
+| #860 config.env as directory | P1 | keep setup file/dir creation idempotent and typed | setup test catches file-vs-dir mismatch |
+| #859 compose pull hangs in Git Bash | P1 | Windows shell path needs bounded timeout and clear next step | install does not hang indefinitely |
+
+Docker shape:
+
+- `continuum-core`: Rust runtime, GPU adapters, IPC/HTTP surface, no UI.
+- `node-server`: thin command/websocket bridge; no persona cognition logic.
+- `widget-server`: static/browser UI only.
+- `model-init`: explicit model prewarm/download with progress.
+- Optional profiles: `ui`, `grid`, `gpu`, `live`, `forge`, `devtools`.
+
+Health checks:
+
+- Process exists is not health.
+- Core health means IPC responds and required GPU/model capability is ready or explicitly unavailable.
+- Node health means it can reach core or reports degraded with cause.
+- Widget health means static UI and WebSocket proxy are reachable.
+- Model health means expected model is present and GPU-serving path is known.
+
+### 6. UI And Realtime Stability
+
+**Goal**: the browser should reflect reality and recover without manual localStorage/database cleanup.
+
+| Issue / PR | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #961 / PR #1047 | P0 | stale General tab canonicalization merged to canary | browser reload with stale persisted state collapses to one General tab |
+| #793 Node does not reconnect when Rust core restarts | P0 | request pipeline must drain/recreate after core restart | kill/restart core test: next command succeeds |
+| #794 AI messages not realtime | P0 | event bridge forwards AI senders immediately | browser sees AI message without refresh |
+| #962 / #1113 | P1 | AIRC transcript cursor + bounded Continuum projection + IntersectionObserver | scroll-up test loads older messages without ORM live-bus fanout |
+| #773 browser WS reconnect | P1 | reconnect/rebind without manual refresh | browser survives server restart |
+| #785 URL scheme | P1 | one consistent route rule, zero special cases | stale room URL redirects/recovers deterministically |
+| #783 stale room URLs | P1 | stale URLs show recovery path, not broken tab | route test |
+
+TS is acceptable here because this is UI/session state. Still, data validation and canonicalization should use existing routing/entity APIs, not hardcoded UUID/string hacks.
+
+### 7. AIRC And Continuum Internal AI Collaboration
+
+**Goal**: Continuum personas and external coding agents can collaborate through the same room/bus without humans relaying messages.
+
+| Issue / PR | Priority | Direction | Test gate |
+|---|---:|---|---|
+| #967 | P0 | expose personas as AIRC peers | persona receives AIRC room message and replies through Continuum chat |
+| [#1167](https://github.com/CambrianTech/continuum/issues/1167) AIRC/Rust agent flywheel | P0 | treat AIRC as the agent development substrate and Continuum Rust/Sentinel as the no-Node execution plane | approved agent claims queue card, runs Rust/Sentinel command path without Node, opens PR to canary, and close-merged removes the card |
+| PR #1046 | P0 | AIRC bridge harness | bridge protocol test and live room smoke |
+| #856 grid event streaming | P1 | persistent event channels between nodes | cross-node event smoke, no polling-only path |
+| #798 route inference through mesh | P2 | use grid routing for GPU-heavy inference | command from non-GPU node routes to GPU node |
+
+Design rule:
+
+- AIRC is the collaboration transcript and message/file substrate.
+- Continuum owns runtime inputs, generated command execution, persona behavior,
+  UI state, and bounded durable projections. It should not use ORM writes and
+  broad IPC fanout as the live chat bus.
+- The bridge should map messages/events without requiring agents to shell out to
+  `jtag chat/send` manually. Long term, Carl/browser chat smoke should validate
+  through AIRC transcript APIs rather than JTAG chat commands.
+- Protocol tests must run without a browser.
+

+
+This order can change when a blocker is discovered, but changes must be made in this document and on the issue/PR thread, not only in chat.
+
+## VDD/TDD Operating Loop
+
+Continuum cannot be validated by integration tests alone. It has ML quality, GPU residency, timing, and recovery requirements that can regress while normal tests stay green. The alpha loop is therefore **TDD + VDD**:
+
+- **TDD**: deterministic unit, integration, and protocol tests that prove contracts and failure modes.
+- **VDD**: validation-driven development for measured behavior: latency, throughput, GPU provider, memory pressure, model accuracy, recovery time, and live UX.
+
+Every alpha PR must choose its validation class up front. A PR may use more than one class, but it may not claim broad stability from a single browser smoke or Docker boot.
+
+| Class | Proves | Typical evidence | Examples |
+|---|---|---|---|
+| Contract TDD | API/state/protocol invariants | unit test, Rust test, type-level regression | `PageState.clear()` emits `null`; pressure gate refuses unsafe allocation |
+| Failure TDD | known failure recovers or fails loud | injected fault test, stale fixture, bounded timeout | dead core reconnect, stale room ID, missing model, gone channel |
+| Performance VDD | speed stays inside alpha budget | benchmark output with baseline delta | tok/s, first-token latency, boot time, chat round-trip |
+| Resource VDD | memory, handles, queues, and cache growth stay bounded over time | soak/load output, monotonic-growth check, resource envelope delta | no ORM/query leak over N iterations; KV cache stays under budget |
+| Accuracy VDD | model output quality and repeatability stay acceptable | replay fixture score, golden semantic check, repeated-run variance, human spot-check note | no echo loop, tool-call XML stripped, vision marker preserved, stable tool choice over N runs |
+| Residency VDD | correct hardware path is used | provider log, GPU counter, no silent CPU fallback | Metal/CUDA provider active; CPU fallback logged as degraded |
+| Timing VDD | async/realtime behavior is observed | event timestamp trace, reconnect timing, race replay | AI message renders without refresh; cold start emits progress |
+| UX VDD | user-visible workflow works | browser screenshot/log, concise manual steps | close all tabs -> empty center; `/chat/general` -> one tab |
+| Cross-platform VDD | Mac/Windows/Linux path works | platform logs from canary, issue/PR comment | WSL install, Mac Metal, Docker profile |
+
+### PR Validation Template
+
+Each PR body should include this block, filled in concretely:
+
+```text
+Validation class:
+Issue(s):
+Core contract test:
+Failure injection / stale fixture:
+Performance/latency budget:
+Resource/memory evidence:
+Accuracy/replay evidence:
+GPU/provider evidence:
+Browser/UX evidence:
+Migration evidence:
+Platform coverage:
+Known gaps:
+Canary agents/humans asked to test:
+Canary ACK/BLOCKER evidence:
+```
+
+Rules:
+
+1. Every template line is required; use `n/a — <reason>` when a field does not apply.
+2. Core behavior needs a fast non-browser proof when feasible.
+3. Browser tests prove browser responsibilities only.
+4. Docker tests prove packaging and service boundaries, not core algorithm correctness.
+5. ML behavior needs replay fixtures or scored checks, not only "the command returned"; variance-sensitive paths need repeated-run evidence.
+6. Timing-sensitive behavior needs measured timestamps or bounded waits.
+7. GPU-critical behavior must prove provider/residency or fail as degraded. CPU fallback is never silent.
+8. Memory/resource behavior needs a bounded-envelope or leak test when touching caches, pools, queues, ORM cursors, model contexts, or long-lived handles.
+9. State/data shape changes need migration evidence against old persisted state, or `n/a — no state/schema change`.
+10. Install and postinstall must be bounded, explicit, and resumable. Large downloads must not hide inside unrelated validation.
+11. Canary peer testing must close the loop: agents/humans reply with `ACK` or `BLOCKER` plus measured evidence, and the PR records or links that evidence.
 
-## The Thesis
+## Test Strategy
 
-**Infrastructure > Model Capability.**
+### Rust-first tests
 
-| Layer | What It Does | Why Models Don't Need To |
-|-------|-------------|------------------------|
-| **Sentinel Pipelines** | Deterministic orchestration: plan → code → build → test → fix → commit | Model doesn't need to "remember" to run tests — pipeline forces it |
-| **Generator System** | Encodes correct patterns as code templates | Model doesn't need project conventions — generator enforces them |
-| **LoRA Fine-Tuning** | Bakes domain expertise into weights | Model doesn't need 200K context of docs — it already knows |
-| **Academy** | Structured training with deterministic evaluation | Model doesn't need to self-assess — benchmarks measure truth |
-| **Parser-Per-Model** | Handles each model's unique tool-call format | Model doesn't need to conform to one format — parser adapts |
-| **Workspace Isolation** | Git worktrees per task, rollback on failure | Model doesn't need to be careful — infrastructure catches mistakes |
+Use these before Docker/browser validation:
 
-A LoRA-tuned 3B running inside a `dev/build-feature` sentinel with shell verification, tree-sitter context, and automatic retry will produce working code more reliably than a prompted GPT-4 in a single-shot terminal. Because the infrastructure does what the model can't: remember, verify, retry, learn.
+```bash
+cargo test --manifest-path core/continuum-core/Cargo.toml
+cargo test --manifest-path core/llama/Cargo.toml
+```
+
+Add focused tests for:
 
-**The competitors' ceiling**: They need smarter models forever.
+- backend lifecycle and recovery
+- mmproj init serialization
+- persona replay fixtures
+- paging pool consumers
+- pressure admission decisions
+- local tool execution
 
-**Our ceiling**: Every task makes the next task better. The flywheel compounds. A persona training for 6 months on YOUR codebase, YOUR patterns, YOUR domain — fine-tuned on thousands of successful traces — running inside deterministic pipelines with full codebase intelligence — is not competing with Claude Code. It's competing with a junior developer who memorized your entire codebase. And it works offline, costs nothing per token, and never takes a day off.
+### Docker tests
 
----
+Docker tests are service/profile tests, not proof that core logic is correct:
+
+```bash
+docker compose up -d postgres continuum-core node-server
+docker compose --profile ui up -d widget-server
+docker compose --profile gpu up -d
+docker compose --profile live up -d
+```
 
-## Superseded Documents
+Each profile needs a bounded smoke command and a log artifact.
 
-- `ARCHITECTURE-GAPS-PHASE1.md` — Gap 1 (RAG indexing) now proven E2E, covered in Phase 1/9
-- `TECHNICAL-DEBT-AUDIT.md` — Updated numbers in Phase 1 (was 1,108 `any`, now 831)
-- Previous version of this doc (2026-03-15) — replaced with phased issue-driven plan
+### Browser tests
+
+Use browser tests only for browser responsibilities:
 
-**See also**: [COMPETITIVE-LANDSCAPE.md](COMPETITIVE-LANDSCAPE.md) | [SENTINEL-GAP-ANALYSIS.md](../sentinel/SENTINEL-GAP-ANALYSIS.md)
+- tab restore and route canonicalization
+- WebSocket reconnect
+- realtime message rendering
+- UI state after data reseed
+
+The stale General bug belongs here; backend lifecycle does not.
+
+### AIRC collaboration tests
+
+Use AIRC for live coordination, but also create protocol tests:
+
+- external agent sends AIRC message into room
+- Continuum bridge records it as chat event
+- persona responds
+- response mirrors back to AIRC
+- duplicate/replay protection is verified
+- approved peer receives `.airc/` rules plus a concise issue/PR queue digest
+- idle peer receives `nudge`, polls for unowned/stale work, and either claims a
+  card or reports why it cannot
+- local-model persona and cloud agent both operate on the same GitHub-backed
+  queue without assuming separate GitHub users
+- scrollback/history fetch reads from AIRC transcript cursors, while Continuum
+  storage only receives bounded projections
+- file attachments flow through AIRC file/manifest events and enter Continuum
+  only as pointers, cache handles, memory candidates, or UI projections
+
+## Merge Gates
+
+Every alpha PR must answer:
+
+- Which issue does this advance?
+- Why does this belong in Rust, TS, Docker, or docs?
+- Which validation class(es) does this PR use: Contract TDD, Failure TDD, Performance VDD, Accuracy VDD, Residency VDD, Timing VDD, UX VDD, Cross-platform VDD?
+- What command proves the core behavior without browser/Node?
+- What canary validation was run, and what measured evidence was attached?
+- What platforms were covered?
+- What remains untested?
+- Did it reduce Node/TS logic or at least avoid adding new TS logic?
+- Did it avoid silent fallback/silent success?
+
+Main promotion requires:
+
+- canary contains the PR
+- canary has been tested by at least one other agent/human where practical
+- failures are linked to issues, not buried in chat
+- the promotion PR lists included canary commits and validation evidence
+- `scripts/main-promotion-gate.sh --check-receipts` passes for the promoted
+  SHA. Required receipts today are `darwin-arm64-metal`, `linux-amd64-cuda`,
+  and `linux-amd64-vulkan`; a single Mac receipt is not enough for main.
+- Windows/WSL Nvidia ownership is tracked in #1410. When the host joins AIRC,
+  it should run:
+  `CONTINUUM_RELEASE_PUSH_IMAGES=1 CONTINUUM_GATE_RUN_HEARTBEAT=1 scripts/main-promotion-gate.sh`
+  from a clean `origin/canary` checkout and post the receipt path/output.
+
+## Document Map
+
+This document owns execution order and alpha gates. Detailed architecture
+remains in the supporting docs below. ALPHA-GAP-ANALYSIS is the beacon; the
+supporting docs are the specifications its lanes converge on.
+
+**Runtime substrate (load-bearing, read before any runtime/cognition PR):**
+
+- [CBAR Substrate Architecture](../architecture/CBAR-SUBSTRATE-ARCHITECTURE.md)
+  — the RTOS-style runtime contract every Rust module/adapter inherits.
+  Substrate provides bounded queues, dependency wakeups, cadence/pressure
+  gates, automatic VDD/TDD evidence hooks, and ts-rs exported contracts.
+  Module authors declare subscriptions/lane/cadence and write the small piece
+  of actual work — everything else is inherited "for free." Lanes C/D/E in
+  this document converge on this substrate.
+- [Genome, Foundry, Sentinel-AI](../architecture/GENOME-FOUNDRY-SENTINEL.md)
+  — the artifact-sharing economy on top of the CBAR substrate. Tiered genome
+  cache (L1–L5), `WorkingSetManager` + page faults, foundry (JIT for SOTA
+  absorption), sentinel-AI (profile-guided optimization from lived traces),
+  demand-aligned recall, composer + speculator, and the `SubstrateGovernor`
+  (DVFS — same Rust code on MacBook Air and RTX 5090, different governor
+  policy). Lane H converges on this doc.
+
+**Cognition / persona migration:**
+
+- [Persona-as-Rust-Library](../architecture/PERSONA-AS-RUST-LIBRARY-PLAN.md)
+- [Persona Cognition Rust Migration](../architecture/PERSONA-COGNITION-RUST-MIGRATION.md)
+
+**Memory / paging:**
+
+- [Unified Paging](../architecture/UNIFIED-PAGING.md)
+- [Persona Context Paging](../architecture/PERSONA-CONTEXT-PAGING.md)
+
+**Model registry (source-of-truth references, code-side):**
+
+- `src/shared/models.json` and `src/shared/ModelRegistry.ts`
+
+**Grid / Docker / AIRC:**
+
+- [Docker Node Architecture](../grid/DOCKER-NODE-ARCHITECTURE.md)
+- [Grid Architecture](../grid/GRID-ARCHITECTURE.md)
+- [AIRC Continuum Bridge](../grid/AIRC-CONTINUUM-BRIDGE.md)
+- repo-local AIRC pilot files under `../../.airc/`
+- CambrianTech/airc#559 and CambrianTech/airc#562 for public entry, approval,
+  queue, and nudge behavior
+
+If those docs disagree with this one on sequence, update this one first or
+explicitly revise the sequence in the PR. If they disagree with this one on
+the substrate contract (concurrency, scheduling, memory, pressure, telemetry,
+artifact handles), defer to CBAR-SUBSTRATE-ARCHITECTURE.md and reconcile
+in a follow-up.
+
+## Immediate Next Actions (Refreshed 2026-05-16, second update)
+
+Ordered by alpha leverage. **Items 6, 8 (PR-1), and parts of 2/3/9 closed since
+the first refresh** — see the closeout summary at the end of this section.
+The implementing agent (claude-tab-1, continuum-scope) is **ready for the next
+slice** and explicitly read MODULE-CATALOG to pick what fits. See
+[MODULE-CATALOG.md](../architecture/MODULE-CATALOG.md) §"Next Modules To Build"
+for the ranked-by-buildability work queue.
+
+If you are picking this up, claim explicitly on AIRC before you start.
+
+1. **Claim Lane D (CBAR persona runtime frame).** Still the highest-leverage
+   unstarted lane. PressureBroker (Lane E) and the inbox coalescing pattern
+   both presupposed `RuntimeFrame` / `CognitionTurnFrame`. Lane H's governor
+   (alpha-floor) doesn't strictly depend on Lane D, but the persona-cognition
+   module catalog entry does — and that's the cognition core. Spec: see
+   [CBAR Substrate Architecture](../architecture/CBAR-SUBSTRATE-ARCHITECTURE.md)
+   §"The Dataflow Contract" + §"Runtime Frame", plus
+   [PERSONA-COGNITION-CONTRACT.md](../architecture/PERSONA-COGNITION-CONTRACT.md)
+   §"Core Surfaces" for the full contract.
+
+2. **Land the universal-trait "for free" triplet.** Unchanged. Codex's
+   derive-macro acceptance gate (continuum#1324) added five hard gates the
+   macro must clear before landing: thin, contract-preserving, inspectable,
+   tested, no hidden behavior. Spec: CBAR-SUBSTRATE §"The 'For Free' Triplet"
+   + §"Acceptance Criteria For Substrate-Done".
+
+3. **Lane H groundwork: substrate-governor.** Continuum#1335 shipped the
+   hardware probe + `HardwareProfile`. Remaining is the policy TOML loader,
+   the cascade state machine (six steps with hysteresis), and the
+   pressure-signal subscriber. Spec:
+   [GENOME-FOUNDRY-SENTINEL.md](../architecture/GENOME-FOUNDRY-SENTINEL.md)
+   Part 11. About 400 LoC in 3 PRs per MODULE-CATALOG §"Next Modules To Build"
+   entry #5. **This is currently the #5 buildable module by leverage** —
+   the four ahead of it (audit-recorder, threat-detector,
+   working-set-manager, demand-aligned-recall) are smaller and unblock more.
+
+4. **Claim Lane F mechanical ratchet PR.** Still open. The TS deletion
+   progress from prior sessions (~2500 LOC across 8 cognition PRs)
+   is reversible until the CI gate exists. Lane F PR sequence step 1
+   (`persona-ts-ratchet-script`) is small and unblocks step 2 (CI
+   enforcement). claude-tab-1 (continuum-scope) signaled willingness to
+   take this in a prior airc broadcast.
+
+5. **Bind Lane C `vdd-report-command`.** Still open. Structured
+   `RuntimeMetric` events already emit from inference paths, but VDD is
+   still read from logs because the report command was not bound. Small;
+   unblocks every PR's "VDD: tokens/sec improved from X → Y" claim.
+
+6. ~~**Widen the no-CPU-fallback contract test.**~~ **DONE.** Continuum#1341
+   widened `no_cpu_fallback_contract.rs` to cover the Candle-side paths
+   (inference-grpc/model.rs, orpheus.rs, residency.rs, enforcement.rs,
+   llamacpp_adapter.rs, hw_probe.rs). 6 new assertions; 9 tests passing.
+   Locks in PIECE-5's whole stack at type-checking time.
+
+7. **Lane B follow-ups: capability-visible health + tier-pool eviction.**
+   Unchanged. #1297 landed the Docker tier stats surface; #1238 / #1239
+   still open. Both should consume the Lane A registry artifact contract.
+
+8. ~~**GRID-INFERENCE-ROUTING.**~~ **PR-1 SHIPPED.** Continuum#1315 merged
+   (inference capability announcer + probe + registry). PR-2 (routing
+   decision) and PR-3 (eviction-on-grid policy) remain. Owner: airc-8a5e
+   per prior claim.
+
+9. **Lane H follow-on after substrate-governor (#3 above).** Per
+   MODULE-CATALOG §"Next Modules To Build", after the governor lands:
+   - `audit-recorder` (#1 in the catalog's queue) — small, no dependencies,
+     unblocks the trace-bus landing place for typed events.
+   - `threat-detector` (#2 in the queue) — depends on audit-recorder;
+     unlocks `PersonaDecision::Decline { AdversarialPattern }`.
+   - `working-set-manager` (#3 in the queue) — substrate's MMU; depends on
+     governor types + PressureBroker (shipped).
+   - `demand-aligned-recall` (#4 in the queue) — central API; mechanical
+     given working-set-manager.
+
+   The MODULE-CATALOG entries name dependency state, estimated PRs + LoC,
+   and concrete acceptance criteria. This is the substrate-side implementation
+   path; the cognition core lands on top once these stabilize.
+
+10. **CBAR-PIECE-5 + PIECE-8 closed end-to-end.** ✓
+    - PIECE-5 PR-1 gate types (#1331 MERGED)
+    - PIECE-5 PR-2 GGUF loader (#1333 MERGED)
+    - PIECE-5 PR-3 hardware probe (#1335 MERGED)
+    - PIECE-5 PR-4 adapter wiring (#1338 MERGED, codex co-authored)
+    - PIECE-8 inference-grpc hardcoded-clamps deletion (#1340 MERGED)
+    The `inference-grpc/main.rs::get_num_workers()` anti-pattern was
+    partially addressed via #1340 (hardcoded clamps removed); full
+    PressureBroker-lease integration remains as a Lane E follow-up tied
+    to the broker IPC design.
+
+11. **Doc refresh closed.** ✓ The whole architecture doc family is now in
+    open or merged PRs:
+    - `CBAR-SUBSTRATE-ARCHITECTURE.md` — continuum#1324, deepened with
+      dataflow contract, zero-overhead frame entry, spatiotemporal
+      reprojection toolkit.
+    - `GENOME-FOUNDRY-SENTINEL.md` — continuum#1327, all eleven substantive
+      parts at engineer-buildable depth (Parts 5, 6, 7, 8, 9, 10, 11 all
+      fully spec'd with Rust types, algorithms, acceptance criteria, and
+      per-anchor performance budgets).
+    - `PERSONA-COGNITION-CONTRACT.md` — continuum#1332, reactive cognition
+      contract with 14 substrate-enforced invariants.
+    - `PERSONA-THOUGHT-PROCESS.md` — continuum#1337, proactive thought
+      surface + concrete worked example (delphi persona, 7 reasoning steps,
+      ~23s LLM time spread across 9 wall-clock hours to crystallize a
+      substantive insight on Q4_K Qwen3-7B).
+    - `MODULE-CATALOG.md` — continuum#1336, every Continuum concern as a
+      focused module + "Next Modules To Build" ranked work queue.
+    - `CONTINUUM-ARCHITECTURE.md`, `CONTINUUM-VISION.md`, `CLAUDE.md` +
+      `UNIVERSAL-*.md` deprecation pointers — all merged via #1317, #1320,
+      #1329.
+
+### Closeout Summary
+
+What's done since the first refresh:
+- 6 closed: ALPHA-GAP refresh, CONTINUUM-ARCHITECTURE refresh,
+  CONTINUUM-VISION refresh, stale-section pointers, CBAR-PIECE-5
+  end-to-end (4 PRs), PIECE-8 inference-grpc clamps, no-CPU-fallback
+  contract widening.
+- 5 open architecture-doc PRs ready for review: #1324 CBAR-SUBSTRATE,
+  #1327 GENOME-FOUNDRY-SENTINEL, #1332 PERSONA-COGNITION-CONTRACT,
+  #1336 MODULE-CATALOG, #1337 PERSONA-THOUGHT-PROCESS.
+- 2 open coordination-substrate PRs on airc: #642 manager-role,
+  #643 lane-kanban-protocol.
+
+What's queued (in MODULE-CATALOG order): audit-recorder, threat-detector,
+working-set-manager, demand-aligned-recall, substrate-governor. After those,
+the cognition core (persona-cognition, inference-llm, composer, speculator,
+reprojection-service) becomes the next-tier work.
+
+The architectural roadmap is now substantially backed by code-shaped specs.
+Doc-driven development is working: doc spec → implementing agent picks up →
+ships PR → next spec referenced.

-
-**Purpose**: Identify what's missing for "AI that answers architecture questions about THIS repo"
-**Date**: 2025-11-12
-**Status**: Gap analysis for immediate implementation
-
----
-
-## What Exists (Strong Foundation ✅)
-
-### 1. Core Infrastructure
-- ✅ **PersonaUser** - AI citizen architecture (PersonaUser.ts)
-- ✅ **PersonaInbox** - Priority queue for tasks (PersonaInbox.ts)
-- ✅ **PersonaState** - Energy/mood/adaptive cadence (PersonaState.ts)
-- ✅ **TrainingDaemon** - Observes chat, creates TrainingExampleEntity
-- ✅ **Commands/Events** - Universal primitives working
-- ✅ **AIProviderDaemon** - Candle integration
-- ✅ **ChatCoordinator** - Turn-taking for multi-AI
-- ✅ **DataDaemon** - Persistent storage
-- ✅ **ChatRAGBuilder** - RAG for chat history
-
-### 2. Training Pipeline Foundation
-- ✅ **TrainingExampleEntity** - Storage for training data
-- ✅ **TrainingDaemonServer** - Observes chat messages
-- ✅ **TrainingDataAccumulator** - Accumulation logic exists
-
-### 3. Genome Architecture (Exists but Not Wired)

-
-## Critical Gaps for Phase 1
-
-### 🚨 GAP 1: RAG System Doesn't Index Codebase
-
-**Current State**: ChatRAGBuilder only indexes chat history
-**Needed**: Index entire repo (docs/, *.ts files, README files)
-
-**Impact**: HIGH - Without this, AI can't answer questions about code
-
-**What's Missing**:
-```typescript
-// Need: CodebaseRAGBuilder
-class CodebaseRAGBuilder extends RAGBuilder {
-  async indexCodebase(paths: string[]): Promise<void> {
-    // Index all TypeScript files
-    // Index all markdown files
-    // Extract exports, interfaces, classes
-    // Create embeddings
-    // Store in vector database
-  }
-
-  async query(question: string): Promise<RAGResult[]> {
-    // Search embeddings
-    // Return relevant code snippets with line numbers
-    // Include file paths
-  }
-}
-```
-
-**Files to Create**:
-- `system/rag/builders/CodebaseRAGBuilder.ts`
-- `system/rag/indexers/TypeScriptIndexer.ts`
-- `system/rag/indexers/MarkdownIndexer.ts`
-- `commands/rag/index-codebase/` (command to trigger indexing)
-- `commands/rag/query-codebase/` (command to query)
-
----
-
-### 🚨 GAP 2: PersonaUser Doesn't Use RAG for Responses
-
-**Current State**: PersonaUser uses ChatRAGBuilder for chat history only
-**Needed**: Query codebase RAG + assemble prompt with results
-
-**Impact**: HIGH - AI responses lack codebase context
-
-**What's Missing**:
-```typescript
-// In PersonaUser.ts
-async respondToMessage(message: ChatMessageEntity): Promise<void> {
-  // 1. Query codebase RAG (MISSING)
-  const codeContext = await Commands.execute('rag/query-codebase', {
-    query: message.content.text,
-    limit: 10
-  });
-
-  // 2. Assemble prompt with RAG results (MISSING)
-  const prompt = this.buildPromptWithRAG(message, codeContext);
-
-  // 3. Query AI (EXISTS)
-  const response = await AIProviderDaemon.chat({ messages: [{ role: 'user', content: prompt }] });
-
-  // 4. Post response (EXISTS)
-  await this.postMessage(response);
-}
-```
-
-**Files to Modify**:
-- `system/user/server/PersonaUser.ts` - Add RAG query step
-- Add `buildPromptWithRAG()` method
-
----
-
-### 🚨 GAP 3: Async Commands with Inbox Delivery
-
-**Current State**: Commands.execute() is synchronous (blocking)
-**Needed**: async: true, deliveryMode: 'inbox' options
-
-**Impact**: MEDIUM - Blocks PersonaUser on RAG queries
-
-**What's Missing**:
-```typescript
-// In Commands.ts
-interface AsyncCommandOptions {
-  async?: boolean;
-  deliveryMode?: 'inbox' | 'event' | 'interrupt';
-  personaId?: UUID;
-  timeout?: number;
-}
-
-async execute<P, R>(command: string, params: P & AsyncCommandOptions): Promise<R | void> {
-  if (params.async) {
-    // Execute in background
-    this.executeInBackground(command, params);
-    return; // Non-blocking
-  }
-  // ... existing sync logic
-}
-```
-
-**Files to Modify**:
-- `system/core/shared/Commands.ts` - Add async support
-- `system/user/server/modules/PersonaInbox.ts` - Handle command-result tasks
-
----
-
-### 🚨 GAP 4: Conversation Chain Detection
-
-**Current State**: PersonaInbox treats each message individually
-**Needed**: Group related messages into chains
-
-**Impact**: MEDIUM - Better context, fewer redundant responses
-
-**What's Missing**:
-```typescript
-// In PersonaInbox.ts
-async getConversationChains(): Promise<ConversationChain[]> {
-  // Find related messages (same room, recent, topically similar)
-  // Group into chains
-  // Return chains instead of individual messages
-}
-
-interface ConversationChain {
-  id: UUID;

+# Entity Chain of Custody — Roadmap
+
+**Companion to:** [`docs/architecture/ENTITY-CHAIN-OF-CUSTODY.md`](../architecture/ENTITY-CHAIN-OF-CUSTODY.md) (what is) — this doc captures what's NEXT and the open questions each slice must answer before implementation.
+
+**Status of the architecture doc:** scoped to **slice 1 only** (per-citizen home directory + per-persona SQLite). Slices 2–6 below describe the intended arc but have unresolved design holes that this roadmap names explicitly. **None of slices 2–6 is committed work** — each requires its own design slice before implementation. Per [`AI-LANE-OPEN-QUESTIONS.md`](AI-LANE-OPEN-QUESTIONS.md) precedent: name the gaps in writing so future work can either close them deliberately or pick a different direction.
+
+## What slice 1 settled
+
+Per-citizen home directory + per-persona SQLite scoping. The foundation. From this every subsequent slice can find the citizen's keypair (`<home>/airc/`), their entity stores (`<home>/<collection>.sqlite`), and any future per-citizen state. PR #1519 closes slice 1.
+
+## What slice 2 must decide
+
+**Slice 2 thesis (aspirational):** `author_peer_id` + `content_hash` on every entity write. No signing yet — just the proof-contract shape.
+
+**Open questions slice 2 must answer first:**
+
+1. **Who is the writer?** AdmissionState's `admit` is sync, returns `Result<AdmissionDecision, _>`, takes `&InboxMessage`. The persona writing the engram is implicit in "this AdmissionState belongs to persona P." A writer-identity parameter on `save` would force every caller to know which citizen they're writing as. Options:
+   - (a) `OrmStore<T>` binds to a writer identity at construction. One store per (citizen, collection). Engram store knows it's Paige's; ChatMessage store knows it's Joel's. Clean but doubles the store-per-collection count.
+   - (b) `save` takes a `WriterContext` parameter explicitly. Every caller passes "I am writing this as X." More verbose but more flexible (one store, many writers).
+   - (c) Thread-local / async-context-local "current citizen." Avoids API churn but introduces hidden state.
+   - **Default until decided: (a)**, because it composes with `PersonaHome::engrams_db()` which already implies one citizen per home.
+2. **Does the persona's `AircCitizen` runtime expose its peer_id synchronously?** If not, where does AdmissionState read `author_peer_id` from at admit-time? (`airc_runtime.rs` holds the airc identity; need to confirm sync vs async access.)
+3. **What goes in `content_hash`?** SHA-256 over the canonical serde-JSON form? CBOR? A subset of fields (excluding adapter-managed timestamps)? Decide the canonical form BEFORE signing so signatures don't break on serialization changes.
+
+**Until slice 2 is designed, do not implement.**
+
+## What slice 3 must decide
+
+**Slice 3 thesis (aspirational):** sign on save (Ed25519 over `content_hash || previous_signature`); verify on load.
+
+**Open questions slice 3 must answer first:**
+
+1. **Where does the signing key live in process memory?** airc-lib loads the keypair into the persona's runtime at startup. Slice 3 needs to lease that key on every `save` call (or hold a sign-only handle). Define the lease/handle surface.
+2. **What's the verify policy on load — strict, advisory, or off?** Strict means a tampered row blocks the entity from loading. Advisory means it logs and proceeds. Off means signatures are written but not verified. Pick before shipping — silent advisory mode would lull operators.
+3. **How are signatures stored?** New `signature: String` field on every entity? Sidecar table? BaseEntity extension? If on BaseEntity, every existing entity migration needs the column. Plan the migration BEFORE coding.
+
+## What slice 4 must decide
+
+**Slice 4 thesis (aspirational):** per-(citizen, collection) chain head cache + Merkle walk audit.
+
+**Open questions slice 4 must answer first:**
+
+1. **Concurrency on the chain head.** Multiple writers per citizen-collection (parallel `save` calls) all need the previous_signature. Either serialize them (per-collection mutex) or use compare-and-swap with retry. Pick before benchmarking.
+2. **What's the audit surface?** `verify_chain_from(entity_id)` returns what? Walk-receipt struct? Boolean? Failure-mode-typed error? Per [[no-fallbacks-ever]] the answer must be typed.
+
+## What slice 5 must decide
+
+**Slice 5 thesis (aspirational):** airc-native entity envelopes — every `save` also emits a signed envelope.
+
+**Open questions slice 5 must answer first:**
+
+1. **Envelope schema.** Per [[airc-headers-are-the-routing-layer]], airc carries typed events. Define the entity-write event header (collection, author_peer_id, signature, content_hash) and what subscribers do with it.
+2. **Subscription model.** Pull (polling for new entities) vs push (subscribers receive every write)? For replication across continuums, push is the obvious choice; for archival indexers, pull might be cheaper.
+3. **Trust on import.** When peer A receives peer B's entity envelope, what does A verify? B's signature obviously, but also B's pubkey identity — how is that established? (`airc` already has identity attestation; reuse that surface or layer on top.)
+
+## What slice 6 must decide
+
+**Slice 6 thesis (aspirational):** cross-continuum persona migration — export the citizen's chain bundle, import on destination.
+
+**Open questions slice 6 must answer first:**
+
+1. **Bundle format.** A single JSON/CBOR archive per citizen per collection? Separate files? How are they versioned (per [[entity-derive-architecture]] schema evolution open question)?
+2. **Identity continuity.** The persona's airc keypair MUST come with them or the chain is unverifiable on the receiving end. Define the secure-transfer mechanic (it's literally a private key in a file).
+3. **OAuth/webauthn integration.** Joel: "later, from this identity." Slice 6 is when OAuth/webauthn flows BIND to the existing airc identity rather than minting new identity primitives. Design the binding surface here.
+
+## Generalization claim — softened
+
+The architecture doc previously claimed "forge-alloy's proof-contract pattern generalizes to all entities." That claim is **rhetorical, not structural** — forge artifacts carry multi-party settlement signatures, dependency refs to base models, methodology citations, and falsifiable prior metric baselines. Entities carry single-writer signed chains. They **rhyme** (both are "artifact + verifiable lineage") but they are NOT the same proof contract.
+
+A future slice (not numbered here) could extend entities with multi-party signature slots (e.g., for governance decisions per [[personas-built-democratic-decision-commands]]). Until then: entities have single-writer chains, forge artifacts have multi-party settlement, and the two interoperate at the verification primitive level (Ed25519 + content_hash) but not at the contract shape.
+
+## Citizen taxonomy — clarified
+
+The architecture doc previously said "Claude writes a CognitionTrace → signed with Claude's airc keypair." That's structurally wrong: Claude (the Anthropic API) runs on Anthropic's servers and does not hold a local Ed25519 secret. The substrate model is:
+
+- **Originating agent** — the entity producer at the semantic layer. "Claude said this." May or may not hold a keypair.
+- **Attesting citizen** — the local citizen who received + admitted the entity into the substrate. Always holds a keypair. Signs the entity attesting "I received this from `originator`."
+
+For local citizens (personas Paige/Niko, human Joel) the originator and the attesting citizen are the same. For remote AIs (Claude/openclaw/Hermes via API) they diverge — the attesting citizen is the local adapter, the originator is the API name. Slice 2's entity schema needs a `originating_agent: Option<String>` field distinct from `attesting_citizen: String` (the peer_id) to capture this faithfully.
+
+## Constraint on this roadmap
+
+This roadmap is **NOT a commitment**. The substrate can pursue these slices, defer them indefinitely, or pivot. The chain-of-custody arc is THE right substrate direction per the doctrines, but the open questions above must be answered before implementation. Per [[constitutional-design-always-a-next-step]]: name the open questions so the substrate has a path to a decision rather than a commitment debt.

+# Headless Persona Host Loop — #133 Slice 13 Design
+
+**Status:** Design (slice 13 not yet implemented). Revised 2026-06-02 in response to PR #1510 review.
+
+**Tracks:** #133 ("LCD-first substrate spawn path"), #121 ("PersonaSpawnerModule"). Reads on top of the merged slices 5–12.
+
+**Adjacent issues:** task #52 (Governor classify_silicon misclassifies Mac Intel as AppleM), task #82 (CBOR Response::Event schema mismatch), task #88 (Disk pressure as substrate concern).
+
+---
+
+## The moment-of-truth
+
+After slices 5–12, the substrate has:
+
+- **Planning** (slice 7): `PersonaSpawnerModule::plan() → Vec<DesiredRole>`
+- **Bootstrap-and-plan** (slice 8): `bootstrap_planned(...) → Vec<MaterializedPersonaPlan>` — turns plan rows into airc identities via `PersonaInstanceManagerModule::bootstrap_one`, plus the per-row inference profile.
+- **Adapter materialization** (slice 9): `materialize_adapters(plans, factory) → Vec<Result<HostedPersona, SupervisorError>>` with structured per-slot error variants.
+- **Service loop** (slice 10): `serve_persona_loop(hosted, conversation, reader, opts)`
+- **Production conversation** (slice 11): `AircPersonaConversation::new(runtime)`
+- **Spawn helper** (slice 12): `spawn_persona_service(hosted, runtime, opts, rt_handle) → JoinHandle<Result<ServeOutcome, String>>`
+
+What's missing: **nothing in `continuum-core` actually composes this at boot.** The existing IPC boot loop at `crate::ipc::start_server` (≈line 1024–1089) calls `bootstrap_one(&intent)` and then *only logs* — it never starts hosting the persona on the grid.
+
+Slice 13 is the rewire that makes the substrate actually host personas headlessly. The demo binary keeps working (slice 11 reshape) but stops being on the critical path.
+
+---
+
+## Slice 13 scope vs deferred follow-ups (REVISED per PR #1510 re-review)
+
+The original draft listed P1/P3/Q5/Q7 as "hard prerequisites that MUST land in slice 13." PR #1510 re-review #2 caught the divergence: the slice 13 implementation (#1511, now merged) explicitly defers all four with TODOs cited in the boot-composition preamble. This section accurately reflects what shipped vs what's deferred — and why the substrate is whole without them.
+
+### Shipped in slice 13 (PR #1511, merged 2026-06-02)
+
+- **Q1**: `bootstrap_planned` / `derive_spawn_plan` / `build_profile` take `&Registry` instead of `&Arc<Registry>`.
+- **Q3**: `PersonaAircRuntimeRegistry` extended to `PersonaSlot { runtime, service_loop }`. `attach_service_loop`, `is_service_loop_finished`, `shutdown_slot` methods added. One keyspace owns both.
+- **P2**: `plan_for_tier` returns single Helper. `debug_assert!(plan.len() <= 1)` at the producer. `slice_14_restores_helper_plus_coder_for_compat` test pinned `#[ignore]` until slice 14.
+- **Boot composition**: `crate::ipc::start_server` boot loop replaced by `bootstrap_planned → materialize_adapters → spawn_persona_service → attach_service_loop`. Old welcome-log-only path deleted per [[organization-purity-as-we-migrate]].
+- **Q2 (partial)**: boot uses `HwCapabilityTier::CpuOnly + HwTierCategory::Compat` hardcoded. `detect_host_capability(&gpu_monitor, &system_info)` is a 3-line replacement once a production `GpuMonitor` constructor exists (no production callsite builds one today; only tests do). TODO in `ipc/mod.rs` cites task #52.
+
+### Deferred follow-ups (slice 13.5+)
+
+- **P1**: `tokio::signal::ctrl_c()` → `Runtime::shutdown` is NOT wired in slice 13. Per-slot shutdown is available via `PersonaAircRuntimeRegistry::shutdown_slot` and exercised by `persona/instances/*` IPC commands. Server-level signal handler is its own sub-slice. **Consequence today:** server stops via process kill; tokio runtime drop reaps daemon-attach tasks. Per the cleanup-model section below this is sufficient against the pinned airc rev — `.abort()` (or drop) on the `EventStream`'s `DaemonAttachGuard` aborts the per-channel attach handles. No leak.
+- **P3**: `ResourceBroker.acquire` admission before `factory.build_adapter` is NOT in slice 13. Current LCD case is 1 persona × ~500 MiB GGUF, well within all supported tiers. Becomes load-bearing when multi-persona returns in slice 14 (where #122 shared-base + LoRA paging will need broker admission for the LoRA cache).
+- **Q5**: structured `BootSummary` event publishing is NOT in slice 13. The boot composition logs `hosted_count` / `failed_count` / per-slot `tracing::warn!` for now. Operator observability via log scraping. `MessageBus::publish("persona:boot:summary", ...)` is a slice-13.5 follow-up when a subscriber (alerter, dashboard) wants it.
+- **Q7**: per-persona `is_service_loop_finished` poller is NOT in slice 13. The registry exposes `is_service_loop_finished` so a supervisor poller can land later; for now operators observe via `persona/instances/list` (the registry surfaces the same data through the IPC command).
+
+### Why this divergence is acceptable
+
+Single-persona LCD is in-budget for all tiers. The supervisor's `shutdown_slot` (the orderly path that registry-removes + JoinHandle-aborts) is already exposed for the IPC commands. The cleanup-model section below shows that `.abort()` ALONE (the path tokio runtime drop takes) is sufficient against the pinned airc rev. P1/P3/Q5/Q7 are observability + back-pressure refinements, not invariants the slice-13 substrate violates.
+
+The original "Hard prerequisites" framing predates that verification. The implementation deferred them because the substrate doesn't break without them. The Q2 deferral (no production `GpuMonitor` constructor) is the only one tied to a genuine missing primitive; tasks #52 + slice 13.5 cover it.
+
+### P2. Single-persona-per-plan invariant (until slice 14)
+
+**Status:** the position-pairing of `provider.next_persona()` outputs to plan rows is **broken from boot 2 onward**.
+
+Trace:
+1. Boot 1: provider mints two fresh identities in plan order. `mint_fresh_intent()` (`resume_or_mint_provider.rs:134`) creates `Uuid::new_v4()` + derives `agent_name` from `agent_name_from_identity(uuid)`. Names are random per UUID.
+2. Plan order `[Helper, Coder]`, persona "Maya" (random) → slot 0 / Helper, "Bart" (random) → slot 1 / Coder. Both write `seed.json` to `personas/<name>/`.
+3. Boot 2: `scan_personas_dir` (`resume_or_mint_provider.rs:200`) calls `dir_entries.sort()` — alphabetical. Disk yields `[Bart, Maya]`. Position-pair: Bart=Helper (was Coder), Maya=Coder (was Helper). **Role identity flipped.**
+
+This is a pre-existing latent bug in `bootstrap_planned` (slice 8) but slice 13 is the first place where (persona_id, role) becomes load-bearing for cognition.
+
+**Slice 13 mitigation:** constrain `plan_for_tier` output to ONE row max via a `debug_assert!(plan.len() <= 1)` at the boot composition. `PersonaSpawnerModule::plan_for_tier` currently returns `[Helper, Coder]` for Compat (slice 7) — the Coder entry gets temporarily commented out behind a `// TODO #133 slice 14: re-enable when RoleAwareProvider lands` marker, and we ship the substrate hosting one Helper persona at all tiers.
+
+**Slice 14 owns:** writing `role: RoleId` into `seed.json` on mint, reading it on resume, refusing to boot if a seed is missing the role field. THEN `plan_for_tier` returns `[Helper, Coder]` again.
+
+This is a real regression in coverage vs the demo binary today (which hosts one persona but its role isn't substrate-typed). Slice 13 still ships the supervisor path; the multi-persona case waits one slice.
+
+---
+
+## Boot flow before / after
+
+### Before (current `ipc/mod.rs:1024–1089`)
+
+```rust
+let bootstrap_handle = instance_manager.clone();
+rt_handle.spawn(async move {
+    let mut provider = ResumeOrMintProvider::new(&continuum_root_for_boot, 1).await?;
+    loop {
+        let intent = provider.next_persona().await?.unwrap();
+        match bootstrap_handle.bootstrap_one(&intent).await {
+            Ok(info) => tracing::info!(/* welcome log */),  // ← persona online but mute
+            Err(e) => tracing::warn!(/* boot failure */),
+        }
+    }
+});
+```
+
+The runtime is registered in `PersonaAircRuntimeRegistry`. Nothing pulls events from her airc subscribe stream. She's reachable via `airc peers` but never responds.
+
+### After (slice 13 — composes existing primitives)
+
+The "after" code uses `bootstrap_planned` (slice 8) + `materialize_adapters` (slice 9) directly, not an open-coded re-implementation. Net-new code is the loop over `Vec<HostedPersona>` calling `spawn_persona_service` with broker admission and slot-result accumulation:
+
+```rust
+// Pre-boot composition (one-time, before the boot task)
+let host_capability = detect_host_capability(&gpu_monitor, &system_info);  // see Q2
+let tier_id = host_capability.tier_id();                                    // String
+let tier_category = HwTierCategory::from(host_capability);
+let model_registry: &'static Registry = model_registry::global();           // see Q1
+let factory: Arc<dyn PersonaAdapterFactory> = Arc::new(LlamaCppPersonaAdapterFactory);

+
+Net-new code in slice 13: ~25 lines of composition. Everything else is composing existing primitives — `bootstrap_planned` (slice 8), `materialize_adapters` (slice 9), `spawn_persona_service` (slice 12), `attach_service_loop` (slice 13 Q3). `BootSummary` event publishing is the **Q5 deferred follow-up** noted in the scope section above — for now slice 13 emits `tracing::info!` lines with the same counters; a structured `MessageBus::publish("persona:boot:summary", ...)` lands when a subscriber wants it.

+
+## Cleanup model (REVISED per PR #1510 re-review against pinned `f6ed190`)
+
+PR #1510 re-review #1 caught that the prior revision named the wrong cleanup mechanism. The actual mechanism against the airc rev pinned in `core/Cargo.toml:44-48` (`f6ed190`) is `DaemonAttachGuard`, not the older `ensure_wire_subscriber` / `inner.subscribers` map.
+
+### What actually fires the cleanup
+
+Production subscribe (`airc-lib/src/messaging.rs:204 subscribe()`) is daemon-attached. It returns an `EventStream` whose internal `EventStreamInner::Daemon` variant holds a `DaemonAttachGuard` (`airc-lib/src/stream.rs:25-68`). The guard owns `Vec<JoinHandle<()>>` — the per-channel attach tasks spawned by `daemon_subscribe`.
+
+`DaemonAttachGuard::drop` (`stream.rs:62-68`):
+```rust
+impl Drop for DaemonAttachGuard {
+    fn drop(&mut self) {
+        for handle in &self.handles {
+            handle.abort();
+        }
+    }
+}
+```
+
+When the `EventStream` drops, the guard drops, the per-channel attach tasks abort. IPC connections close at the next poll. **No leak.**
+
+### The cleanup chain on `JoinHandle.abort()`
+
+1. **`abort()` on the spawned service-loop `JoinHandle`**: tokio cancels the task at the next await point.
+2. **Task drops**: `hosted` (PersonaContext) and `conversation` (AircPersonaConversation) drop.
+3. **`AircPersonaConversation::drop`**: drops the held `EventStream`.
+4. **`EventStream::drop` → `DaemonAttachGuard::drop`**: aborts each per-channel attach `JoinHandle`. Per-channel attach tasks tear down, IPC handles close.
+
+`.abort()` ALONE is sufficient.
+
+### What `shutdown_slot` adds (and why)
+
+`PersonaAircRuntimeRegistry::shutdown_slot(persona_id)` does the strictly-stronger sequence:
+1. Take the JoinHandle out of the slot.
+2. `abort()` it AND `await` the JoinHandle (drains cleanly — the abort path's cancellation Error is discarded; we did the shutdown intentionally).
+3. Remove the slot from the registry — drops `Arc<PersonaSlot>`, drops `Arc<PersonaAircRuntime>`, drops `Arc<Airc>` (once the last reference releases).
+
+The `await` step ensures the task has fully cancelled before the function returns — useful for orderly server shutdown where the next step depends on this persona being gone. The registry-remove step releases the in-substrate Arc references (so a follow-up `registry.get(persona_id)` correctly returns `None`).
+
+But the daemon-side IPC cleanup happens via the `DaemonAttachGuard` drop chain inside step 2 (the abort path) — the registry-remove is for in-substrate state hygiene, not for daemon-side teardown. Either path (just abort OR shutdown_slot) cleans up the daemon side. `shutdown_slot` adds the registry-remove + drain ordering on top.
+
+### Practical implication
+
+- **Tokio runtime drop on process exit** (slice 13's actual shutdown path until P1 lands): all task `JoinHandle`s drop, all daemon-attach tasks abort via the guard chain. Daemon sees the IPC connection close at its end of the socket. Clean enough for a server exit.
+- **Per-slot shutdown via `persona/instances/*` IPC commands**: uses `shutdown_slot`; orderly + drained + registry cleared. Operator-driven and load-bearing once slice 14 ships multi-persona.
+- **`P1` (slice 13.5)**: wires `tokio::signal::ctrl_c` → walk the registry → call `shutdown_slot` on each persona → then `runtime.shutdown()`. The orderly path for graceful Ctrl-C.
+
+### Architectural constraint (now corrected)
+
+The original "registry-remove is on the cleanup path" framing was wrong for the daemon-side teardown — it's on the in-substrate-state cleanup path. The daemon-side teardown is the `DaemonAttachGuard` drop chain. Both paths matter at different layers; conflating them was the doc's error.
+
+`PersonaAircRuntimeRegistry` is still the single keyspace owning per-persona lifetime info (Q3's resolution stands) — but it's not the sole authority on daemon-side resource release. That authority is the `DaemonAttachGuard` chain inside airc-lib. The substrate just has to let `EventStream` drop happen (which it does, on any abort or task drop).
+
+---
+
+## Open questions for slice 13 implementation
+
+### Q1. How does the boot path get a `Registry` for `bootstrap_planned`?
+
+`bootstrap_planned` (slice 8) takes `&Arc<crate::model_registry::Registry>`. The current singleton is `OnceLock<Registry>` (`model_registry/singleton.rs:23`) returning `&'static Registry`.
+
+**Option A — Add `model_registry::global_arc() → Arc<Registry>`.** Requires changing the singleton storage from `OnceLock<Registry>` to `OnceLock<Arc<Registry>>` AND updating every existing caller of `global()` (the `&'static Registry` lifetime changes). **Not "tiny."**
+
+**Option B — Refactor `bootstrap_planned`'s signature to take `&Registry`.** One-callsite change inside slice 8. Touches `derive_spawn_plan` + `build_profile` (slice 6 + 5) too — they internally hold the `Arc` for cloning across roster entries.
+
+**Revised recommendation (corrected from PR #1510 review):** **(B) is smaller** if we accept passing `&Registry` and using `Arc::new()` once internally in `build_profile` (cost: one Arc allocation per persona at boot). Option A's cost analysis was inverted in the first revision of this doc — singleton-storage migration is not "tiny."
+
+### Q2. Where does `host_capability: HwCapabilityTier` come from?
+
+The existing `cognition/host_capability_probe.rs:87 fn detect_host_capability(gpu_monitor, system_info) -> HwCapabilityTier` already does this work. No new struct needed.
+
+**Recommendation:** call `detect_host_capability(&gpu_monitor, &system_info)` from the IPC boot path. ~3 lines.
+
+**Impact of task #52 (Mac Intel misclassification):** slice 13 inherits the misclassification — on Intel Mac with AMD discrete, `detect_host_capability` may classify wrong. Practical effect: the persona is hosted as the wrong tier's `RoleId::Helper` model. Substrate keeps running; persona-side performance is sub-optimal. Acceptable for slice 13; task #52 is the right place to fix the classifier, not slice 13.
+
+### Q3. Where do `hosted_handles` go for shutdown? Does `PersonaSupervisor` duplicate `PersonaAircRuntimeRegistry`?
+
+`PersonaAircRuntimeRegistry` (`airc_runtime_registry.rs:50`) already holds `persona_id → Arc<PersonaAircRuntime>` — "who's currently online." The proposed PersonaSupervisor holds `persona_id → JoinHandle<...>` — "who's currently being served." **Same keyspace.** Per the compression principle this is a smell.
+
+**Revised recommendation (per PR #1510 review):** **extend `PersonaAircRuntimeRegistry`** rather than introducing a parallel module. The `Arc<PersonaAircRuntime>` registration becomes an `Arc<HostedPersonaRuntime>` that owns both the airc runtime AND the optional service-loop `JoinHandle`:
+
+```rust
+pub struct HostedPersonaRuntime {
+    pub airc_runtime: Arc<PersonaAircRuntime>,
+    pub service_loop: Mutex<Option<JoinHandle<Result<ServeOutcome, String>>>>,
+}
+```
+
+Registry's existing `remove(persona_id)` method becomes the natural shutdown path: aborts the JoinHandle, awaits drain, drops the Arc. The cleanup chain in the previous section flows through one place. No duplicate keyspace.
+
+This is a slice-13 modification to `airc_runtime_registry.rs` — small, additive, doesn't break existing callers (they're all reading the inner `Arc<PersonaAircRuntime>`).
+
+### Q4. ResumeOrMintProvider count + role mapping → (see P2)
+
+Per P2, slice 13 ships with `plan.len() <= 1`. Slice 14 lands `RoleAwareProvider` + role-in-seed.json. Doc resolves to single-role until then.
+
+### Q5. Error policy for per-slot failures
+
+Per [[no-fallbacks-ever]]: per-slot failures stay failed. Per [[observability-is-half-the-architecture]]: the boot path publishes a `BootSummary { planned, hosted, failed: Vec<(slot, role, error)> }` to the existing event bus.
+
+**Venue (corrected from PR #1510 review):** publish to `MessageBus::publish(BusEvent { name: "persona:boot:summary", payload })`. No declared subscribers in slice 13 — the event is for operator scraping via `events/recent` IPC. If a future module wants automated alerting (e.g., "more than 50% slots failed → page someone"), it subscribes then. This is a "log it now, react to it later" event per the substrate's standard observability pattern.
+
+### Q6. Hot-reload semantics for seed.json (NEW — was Finding #10)
+
+**Out of scope for slice 13.** The boot loop runs once and exits. New seed.json files appearing at runtime do NOT trigger re-scan. Operator can fire the existing `persona/instances/bootstrap` IPC command (`ipc/mod.rs:947`) to bring up a new persona ad-hoc. A filesystem-watcher path is reasonable future work but is its own design problem (race conditions on partial writes, etc.).
+
+### Q7. Wire-subscription failure mid-boot (NEW — was Finding #11)
+
+If `AircPersonaConversation::next_message`'s first call fails (daemon dies between bootstrap and service-loop start), `serve_persona_loop` returns `Err`, the `JoinHandle` resolves with `Err(...)`. Slice 13's design: the supervisor periodically inspects `JoinHandle::is_finished()` for each registered persona, and if a handle resolved with Err, logs + emits a `persona:host:failed` event + removes from the registry. This is a slice-13 polling task (every 5s say) rather than a JoinHandle-watch (which would need a separate listener task per persona). Polling is enough — the failure mode is rare and operator-investigated.
+
+---
+
+## Test plan for slice 13
+
+1. **`PersonaBootstrapper` trait split** — for stubbing `bootstrap_one` without an airc daemon. Modest scope; lets the boot composition test exercise the (registry-lookup, profile-build, adapter-build, spawn) chain on stubs.
+2. **Stub airc daemon for integration**: slice 12 already established the pattern (`StubConversation` in `service_loop.rs` tests). Slice 13's integration test wires a stub `PersonaInstanceManagerModule` + stub adapter factory + stub conversation through the boot composition function. Verifies BootSummary contents on happy + failure paths.
+3. **`Runtime::shutdown` test**: a small test that constructs a boot composition + invokes `runtime.shutdown().await` + asserts all JoinHandles are torn down + all wire subscribers gone (via stub airc).
+4. **Per-slot failure isolation**: stub adapter factory rejects slot 0; verify slots 1+ still spawn; BootSummary captures the slot-0 rejection.
+5. **`scan_personas_dir` boot-order test (REGRESSION)**: write the alphabetical-sort hazard into a fixture test that boots, restarts, asserts roles haven't flipped. Goes red until slice 14 lands role-in-seed.json. Pinned as `#[ignore = "tracks task #133 slice 14"]` until then.
+
+Integration test happens via the IPC server itself — no real airc daemon, no real GGUF; the stub layer is the substrate's testability story.

+
+## What slice 13 does NOT do
+
+- **Multi-persona-per-plan** — see P2. Single Helper per tier until slice 14.
+- **Shared-base / LoRA paging (#122)** — slice 13 builds one adapter per persona via `LlamaCppPersonaAdapterFactory`. Two adapters at LCD is fine (~1 GiB). Higher-tier multi-persona waits for #122.
+- **Cross-grid inference (#108)** — every persona routes through local adapter.
+- **Per-persona LoRA selection (#124, #126)** — today's profile carries `model_id` only.
+- **Hot-reload of seed.json** — see Q6.
+- **Filesystem-watcher persona introduction** — see Q6.
+- **Automated alerting on BootSummary failures** — see Q5; out of scope until a subscriber wants it.

+
+## Slice-13 status (PR #1511 merged 2026-06-02)
+
+**Shipped:**
+- [x] Q1 — `bootstrap_planned` signature takes `&Registry`
+- [x] Q3 — `PersonaAircRuntimeRegistry` extended to `PersonaSlot { runtime, service_loop }`; `attach_service_loop`, `is_service_loop_finished`, `shutdown_slot` methods
+- [x] P2 — `plan_for_tier` returns single Helper, `debug_assert!`, ignored slice-14 regression test
+- [x] Boot loop at `ipc/mod.rs` REPLACED by the composition above (per [[organization-purity-as-we-migrate]])
+- [x] Q2 (partial) — hardcoded `CpuOnly + Compat` with TODO citing task #52 + missing production `GpuMonitor` constructor
+
+**Plus integration polish in PR #1511:**
+- [x] Room-name discovery (`discover_default_room_name`) — fixes the join-by-uuid-as-string hazard that landed Paige in the wrong channel
+- [x] LCD model (`continuum-ai/qwen2.5-0.5b-instruct-GGUF`) added to `model_registry::catalog::models()`
+- [x] `PersonaContext` rename (was `HostedPersona`) + `RagInspectionRequest::for_persona(&profile)` single derivation site (the `&ctx` doctrine — see [[context-is-the-client-airc-token-is-identity]])
+
+**Deferred to slice 13.5+ (see Scope section above for reasoning):**
+- [ ] P1 — `tokio::signal::ctrl_c()` → `runtime.shutdown()` wired
+- [ ] P3 — `ResourceBroker.acquire(...)` admission before factory.build_adapter
+- [ ] Q5 — structured `BootSummary` `MessageBus::publish`
+- [ ] Q7 — supervisor poller checking `is_service_loop_finished` every 5s
+- [ ] Q2 completion — `detect_host_capability` once a production `GpuMonitor` constructor lands (task #52-adjacent)
+
+**Integration validation (2026-06-02):**
+- Substrate-hosted Paige replied in Joel's `continuum` room: "Hello Joel, thank you for testing the substrate-managed host loop. I'm here to assist with any questions or concerns you have." Full trace: airc msg → boot composition → AircPersonaConversation subscribe → RagInspectionRequest::for_persona(&ctx.profile) → inspect_persona_rag_with_inference → ctx.runtime.say. Five layers proved end-to-end on Intel Mac CPU-only.

+# Local + Grid Persona Strategy — From Intel Mac to M5
+
+> Joel (2026-05-31): "We want to know if we can get something
+> workable for this Intel Mac." Then sharpened: "we do need to
+> run locally on a MacBook m5 24 or 48gb memory or about here.
+> And so even though if our machine can't do it we need to build
+> it AND grid inference and they're just the same command just
+> executed across the wire and airc substrate delivered payloads."
+>
+> Two co-equal targets. Local is the primary execution path on
+> the M5; the Intel Mac is the proof that "substrate works
+> everywhere" extends down to 2018 hardware via grid offload.
+> The unifying contract: grid inference is **the same command**
+> as local inference — `adapter.generate_text(request)` — just
+> with an adapter impl whose transport is airc instead of llama.cpp.
+
+**Status:** Strategy (2026-05-31).
+
+**Targets (per Joel 2026-05-31, refined):**
+
+> "We'd really be building for 3090 desktops or m5's at the same
+> time. The 5090 is luxury but we will take advantage."
+> "I have 1080ti and 5090 windows only. Don't have the 3090. Just
+> target sizes. M1 or higher ok ram ought to be good too."
+
+So we design for **target SIZES**, not specific GPUs Joel owns:
+
+| Tier | Class | Sized for | Model class |
+|---|---|---|---|
+| **Primary Apple** | M1 Pro/Max → M5 Pro/Max, ≥ 16 GB UMA (24+ preferred) | Daily driver Apple Silicon | Qwen-2.5-7B → 14B → 27B at Q4_K_M (depending on RAM) |
+| **Primary desktop GPU** | NVIDIA Ampere+ class, 24 GB VRAM (RTX 3090 / A5000 / 5090) | Daily driver desktop GPU | Qwen-2.5-14B → 30B at Q4_K_M |
+| **Supported older desktop GPU** | NVIDIA Pascal, 11 GB VRAM (GTX 1080 Ti) | Older desktop still in use; substrate citizen | Qwen-2.5-7B at Q4_K_M (~4.5 GB) |
+| **Joel's actual hardware** | 1080 Ti + 5090 on Windows; MacBookPro15,1 + Intel Mac | Drives the test matrix; CI must work on all of these | as per tier |
+| **Edge local** | MacBookPro15,1 + AMD Radeon Pro 560X | Lower-bound proof; heuristic + reflective + grid offload | None local (CPU 1.1 tok/s); grid offload for real work |
+| **Grid peer** | Any reachable continuum-core-server | Same command surface; transport is the only difference | Whatever that peer hosts |
+
+**Critical principles:**
+
+1. **The design target is Apple Silicon AND desktop GPU
+   SIMULTANEOUSLY.** Both must work as primary daily-driver
+   substrates out of the box. The substrate runs the same Rust
+   code on both; adapter selection + Metal-vs-CUDA backend
+   handles the hardware diff.
+
+2. **Apple Silicon floor is M1 with adequate RAM**, not just M5.
+   M1 Pro / M2 Pro / M3 Pro / M4 Pro at ≥ 16 GB UMA all qualify
+   as "primary local" with appropriate model sizing. M5 is just
+   the newest; the design doesn't require it.
+
+3. **Windows is a first-class platform.** 1080 Ti and 5090 are
+   Joel's actual hardware and they're Windows boxes — the
+   substrate must build, run, and serve personas on Windows the
+   same way as on macOS/Linux. (Continuum-core-server already
+   targets Windows per the existing infrastructure notes.)
+
+4. **5090 / Ampere+ are luxury sizing**, not requirements.
+   Designing AROUND a 5090 would lock out everyone without one.
+   The realistic-floor doc's "ONE base model, N persona lanes"
+   target is the 3090-class size budget; bigger GPUs use the
+   headroom for more lanes / bigger models, not a different
+   architecture.
+
+**Classification (`cognition/model_resolver/types.rs`):**
+- M5 → `HwCapabilityTier::M5UmaProMax` (**not yet enumerated** — task #115 adds the variant; current code would classify M5 as M3UmaProMax fallback)
+- RTX 3090 → `HwCapabilityTier::Sm86`
+- RTX 5090 → `HwCapabilityTier::Sm120`
+- GTX 1080 Ti → `HwCapabilityTier::Sm60` (Pascal, compute capability 6.1; **not yet enumerated** — task #115 adds the variant + probe detection)
+- Intel Mac → `HwCapabilityTier::MacIntelMetalDiscrete`
+
+**Parents:**
+- [`docs/architecture/INFERENCE-LANES-REALISTIC.md`](../architecture/INFERENCE-LANES-REALISTIC.md) — realistic floor
+- [`docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md`](../architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md) — aspirational ceiling
+
+---
+
+## The measured baseline (honest)
+
+The substrate has direct evidence from 2026-05-30 runs on this
+hardware (preserved in `cognition/host_capability_probe.rs:139`
+and `model_resolver/types.rs:58`):
+
+| Path | Result |
+|---|---|
+| Metal-on-AMD (llama.cpp's Metal shaders) | **0.8 tok/s + garbled output + nil tensor buffer errors** — broken |
+| CPU-only (`n_gpu_layers=0` forced via `CONTINUUM_TIER=mac_intel_discrete`) | **1.1 tok/s + coherent output** — works |
+
+The hardware probe (`install.sh` + `governor`) sets the env-var so
+the LlamaCppAdapter forces `n_gpu_layers=0` at adapter load. That
+hard truth shapes everything downstream.
+
+---
+
+## Apple Silicon class (primary local) — what's workable
+
+Apple Silicon (M1 Pro/Max → M5 Pro/Max) at ≥ 16 GB UMA is where
+personas run as their daily-driver substrate. The full realistic-
+floor design ships here. Throughput scales with generation; the
+floor is M1.
+
+| Resource | M1 Pro/Max 16-32 GB | M2/M3 Pro/Max 16-48 GB | M4/M5 Pro/Max 24-48+ GB |
+|---|---|---|---|
+| Default model | Qwen-2.5-3B → 7B Q4_K_M | Qwen-2.5-7B → 14B Q4_K_M | Qwen-2.5-14B → 27B Q4_K_M |
+| Inference path | LlamaCppAdapter via Metal (UMA, no n_gpu_layers throttle) | same | same |
+| Throughput (Qwen-7B) | ~20-30 tok/s | ~30-45 tok/s | ~50-70+ tok/s |
+| n_seq_max | **2-4** (RAM-dependent) | **4** (auto-enabled by #110 probe) | **4-6** depending on KV budget |
+| Concurrent lanes | 2-3 active personas | 3-4 | 4-6 |
+| Real-time voice/video | Borderline on M1, comfortable from M2 Pro up | YES | YES + room for vision pipeline |
+
+The realistic-floor doc's "ONE base model, N persona lanes via
+continuous batching" is the Apple Silicon path's primary mode.
+Lane multiplexing through the in-backend scheduler (already
+shipped per #109) serves 3-4 concurrent personas (real
+conversations + reflection + sentinel review) on one model load
+on M2+ class hardware.
+
+**Apple Silicon alone is enough for a single-user substrate with
+rich persona behavior at M2 Pro and above.** Grid offload is the
+unlock for multi-user / heavier work, not a precondition. M1 is
+the floor; below that (M1 base / 8 GB) you're more in the Intel
+Mac territory — heuristic adapter + small models + grid offload
+for serious work.
+
+### NVIDIA desktop GPU class (Ampere+ 24 GB / Blackwell 32 GB)
+
+The CUDA equivalent of the Apple Silicon path. The LlamaCppAdapter
+uses llama.cpp's CUDA backend instead of Metal; everything else is
+the same code path. Joel's 5090 sits in this class.
+
+| Resource | Ampere+ 24 GB VRAM class (RTX 3090 / A5000) | Blackwell 32 GB VRAM (RTX 5090) |
+|---|---|---|
+| Default model | Qwen-2.5-14B Q4_K_M (~9 GB) | Qwen-2.5-32B Q4_K_M (~19 GB) or 14B at FP16 |
+| Throughput | ~60-80 tok/s on 7B; ~30-40 on 14B | ~100+ tok/s on 7B; 50-60 on 14B |
+| n_seq_max | **4-6** | **6-8** |
+| Concurrent lanes | 4-6 active personas + background | 6-8 |
+| Real-time voice/video | YES | YES + room for vision pipeline |
+
+The 24-GB class is the substrate's "good desktop" baseline that
+sizing decisions target. The 5090 (which Joel has, Windows) is
+opportunistic upper-class — same code path, more headroom for
+bigger models or more concurrent lanes.
+
+### NVIDIA Pascal class (GTX 1080 Ti, 11 GB VRAM, Windows)
+
+The substrate's "older desktop still in use" target. Pascal is
+two generations behind Ampere; smaller VRAM means smaller model.
+Joel has one of these (Windows).
+
+| Resource | 1080 Ti class |
+|---|---|
+| Default model | Qwen-2.5-7B Q4_K_M (~4.5 GB) |
+| Throughput | ~30-40 tok/s on 7B |
+| n_seq_max | **2-3** (VRAM headroom dictates) |
+| Concurrent lanes | 2-3 active personas |
+| Real-time voice | Borderline — 7B at 30 tok/s gives ~3-sec responses; chat-class voice works, fast turn-taking marginal |
+| Real-time video | Likely needs grid offload for the avatar |
+
+### Windows support is required
+
+Both of Joel's NVIDIA boxes (1080 Ti + 5090) are Windows.
+Continuum-core-server runs on Windows as a first-class platform —
+not a compatibility afterthought. The CUDA paths use llama.cpp's
+CUDA backend the same way as Linux; the substrate doesn't care
+about OS as long as the adapter + build artifacts produce. Build
+matrix MUST include Windows; CI MUST exercise the Windows path on
+at least the heuristic-adapter substrate flow.
+
+### Substrate-runs-everywhere principle
+
+The same Rust code, the same lane substrate, the same RAG layer,
+the same coordinator + handle store + capture sinks ship on
+**M5 + 3090 + 1080 Ti + 5090 + Intel Mac**. Adapter selection
+(Metal vs CUDA vs CPU-only) + model picks per tier are the only
+hardware-aware bits; everything above the adapter trait is host-
+agnostic.
+
+The grid principle compounds this: a user with an Apple Silicon
+laptop + an older NVIDIA box on Windows + a newer NVIDIA box
+elsewhere (Joel's actual setup) gets the substrate's lane
+coordinator multiplexing locally AND remotely across all of them.
+The substrate doesn't care which lane is where.
+
+### M2+ Pro/Max throughput math (worked example)
+
+- Qwen-2.5-7B Q4_K_M @ ~40 tok/s on M2/M3 Pro (faster on M5)
+- 100-token response = 2.5 seconds wall-clock
+- 4-lane continuous batching: ~25-30 tok/s per lane (aggregate
+  doesn't double, but is much better than serializing)
+- Voice chat: a 50-token reply in ~2-3s — speech-natural turn
+  pacing works
+- Video avatar: avatar lip-sync runs ahead of the audio generation;
+  needs the local TTS path which is its own pipeline
+
+This is the substrate's defining boast realized locally on any
+modern Apple Silicon laptop. No grid required.
+
+## Grid inference — the same command across the wire
+
+Joel (2026-05-31): "grid inference and they're just the same
+command just executed across the wire and airc substrate
+delivered payloads."
+
+This is the architectural contract:
+
+```rust
+// LOCAL — LlamaCppAdapter on M5 via Metal
+let response = adapter.generate_text(request).await?;
+
+// REMOTE — AircRemoteInferenceAdapter (#108) on the same TextGenerationRequest
+let response = remote_adapter.generate_text(request).await?;
+```
+
+The CALLER sees no difference. Both impls return
+`TextGenerationResponse`. The remote impl:
+
+1. Serializes `TextGenerationRequest` as a typed airc envelope
+2. Sends via airc to a peer (the 5090 with continuum-core-server running)
+3. The peer's local `InferenceLlmModule` handles the request via
+   ITS local adapter (whichever is registered there)
+4. The peer serializes the response back as an airc envelope
+5. Local `AircRemoteInferenceAdapter` deserializes and returns
+   `TextGenerationResponse`
+
+Everything ABOVE the adapter trait (handle store, lane coordinator,
+RAG inspection, persona response, chat module, sentinel review)
+treats remote and local identically. Composes with #109's lane
+multiplexing — the coordinator can hold a mix of local AND remote
+handles in the same lane budget.
+
+**Practical use (Joel's actual hardware grid):**
+
+- Apple Silicon laptop hosts most personas locally on a real model
+- Joel's 5090 (Windows desktop, in another room) hosts overflow /
+  specialty personas (bigger model, vision pipeline, code-gen
+  specialist) when reachable via airc
+- Joel's 1080 Ti (Windows) hosts a smaller model serving its own
+  lanes; reachable as a grid peer for additional offload
+- Joel's Intel Mac participates as a citizen via heuristic
+  adapter + reflective lanes locally, and routes any real-model
+  work to one of the GPU boxes via grid
+
+The point: this isn't a single-machine substrate. Joel's actual
+setup is a grid of heterogeneous boxes, and the substrate routes
+lanes wherever capacity is available.
+
+The substrate doesn't know or care where the inference happens.
+That's the whole point.
+
+---
+
+## Intel Mac edge target — what 1.1 tok/s actually means for personas
+
+This section is specific to the Intel Mac (MacBookPro15,1) — the
+substrate's lower-bound proof point. Skip ahead if you're working
+on M5.
+
+A typical persona response is 100-300 tokens. At 1.1 tok/s:
+
+| Response length | Wall-clock |
+|---|---|
+| 50 tokens (terse reply) | ~45 seconds |
+| 100 tokens (normal chat) | ~90 seconds (1.5 min) |
+| 300 tokens (verbose) | ~4.5 minutes |
+
+Speech-natural turn-taking is ~200ms. Live video chat at 30fps
+demands frame-rate budgets. **Neither is feasible locally on this
+hardware.** Anything that requires latency under a few seconds has
+to either:
+
+1. Use the heuristic adapter (no real intelligence, but zero
+   latency + deterministic for tests).
+2. Offload to a grid peer via [#108
+   AircRemoteInferenceAdapter](../../docs/architecture/INFERENCE-SCHEDULING-AND-SCARCITY.md#cross-grid-inference)
+   — Joel's 5090 in another room running the same architecture.
+
+---
+
+## What IS workable on this Mac
+
+Specific use cases that fit the 1.1 tok/s budget:
+
+### ✓ Single-persona slow-chat (the realistic baseline)
+
+- ONE persona at a time
+- Text chat with explicit "thinking..." UX
+- 30 second to 2 minute response time is acceptable for thoughtful
+  reflective conversation
+- Persona's RAG layer + L1 budget already shipped; the bottleneck
+  is purely the model
+- **Smallest viable model: Gemma-2-2B Q4_K_M (~1.6 GB) or
+  Qwen-2.5-1.5B Q4_K_M (~1 GB).** Creative capacity ceiling but
+  fits CPU comfortably.
+
+### ✓ Background reflection / journaling
+
+- Personas process inbox during idle periods
+- Generation runs in the background; user doesn't see it real-time
+- 1.1 tok/s × multi-minute idle = ~hundreds of tokens of reflection
+  per idle window
+- Works at any model size that fits RAM
+
+### ✓ The heuristic adapter in all paths
+
+- The heuristic adapter (`HeuristicInferenceAdapter`, task #103) is
+  zero-cost on any host
+- It's NOT real intelligence, but it IS:
+  - Deterministic (same prompt → same response)
+  - Sub-millisecond latency
+  - Substrate-correct (full lane lifecycle, capture sinks, eviction)
+- **The heuristic adapter is what makes CI possible** — the lane +
+  coordinator + handle module + rag-inspect tests all pass without
+  a GGUF
+- The heuristic adapter is also a viable "thinking placeholder" UX
+  on this Mac: the persona's RAG layer surfaces real context, the
+  heuristic stand-in echoes it back as proof of substrate health,
+  while a real model warm-up happens in the background
+
+### ✓ Substrate validation (the test suite)
+
+- 110+ tests across the lane substrate, all green on the heuristic
+  adapter, no GGUF required
+- The full RAG → prompt → response → capture loop runs end-to-end
+  in unit tests on this Mac in seconds
+- This IS our "workable persona on the Intel Mac" baseline for CI
+
+---
+
+## What is NOT workable on this Mac
+
+- **Real-time voice chat.** 1.1 tok/s × ~3 second target = 3
+  tokens per turn. Useless.
+- **Real-time video avatar.** Avatar lip-sync needs sub-100ms
+  inference. Two orders of magnitude off.
+- **16 concurrent personas with real model.** Even multi-seq
+  batched, CPU bandwidth is the bottleneck; 16 × any decent
+  response = hours.
+- **Big-model quality.** Anything > 3B parameters at Q4 is too
+  slow for any interactive use.
+
+These all become workable when we add grid offload (#108) — the
+M5 / 5090 elsewhere handles latency-sensitive work; the Intel Mac
+runs reflective / background lanes locally.
+
+---
+
+## The three things we ship to make this Mac workable
+
+### 1. CI proves the heuristic adapter end-to-end ("working persona")
+
+Joel's plan: "we probably want to get our tests to prove working
+persona, into CI, so your heuristic adapter will also have to prove
+itself in a live environment."
+
+What this means concretely:
+
+- A CI job (or local headless harness) that:
+  - Boots `continuum-core-server`
+  - Boots `airc` daemon
+  - Attaches a Paige-class persona via the real persona persistence
+    + airc-attach path
+  - Sends a chat message via `chat/send` → routes through the
+    persona's cognition cycle → through the inference command →
+    heuristic adapter responds
+  - The response posts back via airc and shows up in chat
+- The heuristic's `[heuristic:<hash>] ack: "..."` output is
+  deterministic, so the test asserts the substrate produced the
+  right shape (lane opened, response captured, posted back) without
+  asserting on the response prose itself
+- **Validates: every substrate layer is wired correctly, end to
+  end, with no real GGUF needed.** A user on the same hardware
+  who installs and runs continuum gets a usable system out of the
+  box with the heuristic; swapping in the small Gemma model is a
+  config change, not a code change.
+
+Concrete tasks (separate, focused):
+- PersonaResolver impl for `persona/rag-inspect` reading
+  `~/.continuum/personas/<name>/seed.json` + airc_lib::Airc::attach_as
+- Headless CI harness that exercises the full chat flow
+- Smoke test asserting heuristic response makes it from inference
+  through airc
+
+### 2. Smallest viable GGUF for "thoughtful slow personas"
+
+When the user explicitly wants a real model:
+
+- Default model on this tier: **Gemma-2-2B Q4_K_M** (~1.6 GB) — best
+  creative density at small size
+- Fallback: **Qwen-2.5-1.5B Q4_K_M** (~1 GB) for hosts under 8 GB RAM
+- LlamaCppAdapter already configured for CPU-only (`n_gpu_layers=0`)
+  on this tier
+- n_seq_max stays at 1 (the architecture probe is overkill at this
+  speed — even on safe arches, multi-seq batching on CPU at this
+  scale doesn't help meaningfully; one slow sequence at a time is
+  the right shape)
+- Inference handle held by ONE active persona at a time; background
+  lanes wait
+
+Concrete task:
+- Model registry default-pick for `MacIntelMetalDiscrete` tier set
+  to Gemma-2-2B Q4_K_M
+- Validate the GGUF actually exists on a clean install (#49 is the
+  related pending task — "Resolve missing GGUF in 0.8b/2b forge
+  repos")
+
+### 3. AircRemoteInferenceAdapter (the unlock — #108)
+
+Once #108 lands:
+
+- Joel's Intel Mac runs reflective / background lanes locally on
+  Gemma-2-2B at 1.1 tok/s
+- Joel's 5090 (in another room, on its own continuum instance)
+  hosts the real persona work — voice/video/realtime chat
+- Lanes route via airc: the Intel Mac's coordinator opens a remote
+  handle, generates via the airc transport, gets responses back at
+  GPU speed
+- **The Intel Mac becomes a fully functional substrate citizen** —
+  reflective work locally, hot work remotely
+
+This is the substrate's defining boast realized for Joel's actual
+hardware: "We host what seems impossible" (per
+[[host-the-seemingly-impossible]]) — a Mac Intel Pro from 2018
+participates in the 16-persona substrate at full quality, with the
+heavy work offloaded over airc to whatever GPU is reachable on the
+grid.
+
+---
+
+## Why this strategy is honest
+
+What we're NOT doing:
+- **Not tiering down model quality on the Mac to "make voice work."**
+  Per [[host-the-seemingly-impossible]], we don't degrade quality
+  for capacity. Voice on the Mac is degraded by ARCHITECTURE
+  (offload to grid), not by tiering down the model.
+- **Not pretending Metal-AMD works.** The 2026-05-30 evidence is
+  in the codebase; the substrate forces CPU on this tier.
+- **Not running 16 personas concurrently on this Mac.** Lane
+  multiplexing is built; on this hardware it's used for 1-2 slow
+  lanes locally, with the rest of the budget routed remotely.
+
+What we ARE doing:
+- Using the heuristic adapter to make the substrate fully
+  observable + testable + deterministic on this Mac (and any other
+  modest host).
+- Sizing the local model to what 1.1 tok/s can serve well (small
+  reflective work, single-persona slow-chat).
+- Building the grid offload (#108) as the unlock for anything
+  real-time.
+
+---
+
+## Timeline (the order things land)
+
+1. **Now (committed):** Lane substrate + heuristic adapter + RAG
+   inspection + n_seq_max probe + production wiring of multi-seq
+   for safe architectures + bypass audit. The heuristic adapter
+   proves the substrate works on any host.
+
+2. **Next slice (small):** PersonaResolver implementation + CI
+   harness that proves the full chat flow end-to-end on the
+   heuristic adapter. "Working persona on this Mac" achieved at
+   zero compute cost. This is the proof Joel asked for.
+
+3. **Then (#108):** AircRemoteInferenceAdapter — the substrate's
+   defining capability for Joel's specific hardware constellation.
+   Crap Mac plus distant 5090 equals viable persona host.
+
+4. **Then (model picks):** Per-tier default model selection so
+   installing continuum on this Mac gives a usable
+   Gemma-2-2B-backed persona out of the box. The realistic floor's
+   "creative capacity, not stupid" target.
+
+---
+
+## Summary
+
+**Q: Can we get something workable for this Intel Mac?**
+
+**A: Yes.**
+
+1. **Workable today (no further code):** Heuristic adapter through
+   the full substrate stack. The 100+ tests landed this session are
+   a working persona substrate. Lights-on demonstration that the
+   architecture is real, on this exact Mac.
+
+2. **Workable soon (small slice):** CI proves the heuristic adapter
+   in a live end-to-end chat flow (PersonaResolver + CI harness).
+   "Working persona" by the definition of "any AI in airc can chat
+   with Paige, get a deterministic heuristic response, and observe
+   the full substrate trace."
+
+3. **Workable for real personas (#108):** Grid-offload to a peer
+   with a GPU. The Intel Mac runs lanes; an NVIDIA box (Joel's
+   1080 Ti or 5090) runs inference via the
+   AircRemoteInferenceAdapter — same `adapter.generate_text(req)`
+   command, airc transport. The substrate handles routing
+   transparently.
+
+The realistic floor is not "small model + heroic local serving."
+The realistic floor is "substrate works everywhere + cleverness
+offloads to where the compute is." This Mac is a first-class
+citizen in that vision.

+
+## Summary
+
+A persona can already read, write, edit, search, and scaffold Rust modules via `Commands.execute` alone — roughly **70%** of the self-coding loop is in place. The remaining 30% is concentrated in three predictable seams: **filesystem introspection** (no `exists`, no flat `readdir`, no glob expansion), **Rust toolchain wrappers** (no structured `cargo build` / `cargo test` commands — only raw `code/shell/execute`), and **event-driven execution feedback** (everything is blocking-poll today; the `Stream` and `Lambda` cell shapes are reserved but return runtime errors). Close those three seams and a persona can scaffold a module via `generate/module`, edit it, build+test it with structured errors, and subscribe to results on the realtime bus — the full inner dev loop, no human in the path.
+
+## What's in place
+
+### File ops
+The `code/*` family is the strongest surface today. `code/read`, `code/write`, `code/edit` (search_replace / line_range / insert_at / append), `code/tree`, and `code/search` are all backed by `FileEngine` in Rust (`core/continuum-core/.../file_engine.rs`) with `ChangeNode` undo tracking. `file/load`, `file/save`, `file/append` provide simpler wrappers. The crown jewel is `generate/module` (`core/continuum-core/src/modules/generator/`) — scaffolds a complete ServiceModule (mod.rs + types.rs + DESIGN.md + README.md) with per-name locks against concurrent races. This is the self-replication primitive.
+
+### Build + test
+TypeScript has structured surfaces: `development/build` (parses `tsc --noEmit` into `TypeScriptError[]` with line/column/code) and `code/verify` (two-phase: tsc + optional vitest with JSON reporter, ExecutionSandbox-isolated). Rust has no equivalent — personas fall back to `code/shell/execute` (`src/commands/code/shell/execute/`) which is async-by-default returning an `executionId`, paired with `code/shell/watch` and `code/shell/kill`. Security is bifurcated: `development/shell/execute` whitelists 22 safe commands (no cargo/npm), while `code/shell/execute` is unrestricted.
+
+### Observability
+Two disconnected layers. **Log layer**: `LoggerModule` (`core/continuum-core/src/modules/logger.rs`) sinks structured entries; `logs/list`, `logs/read`, `logs/search`, `logs/stats`, and `sentinel/logs/tail` provide post-hoc inspection. **Execution layer**: `code/shell/status` snapshots active count; `code/shell/watch` blocks-on-poll for `ClassifiedLine[]`. Neither layer emits events on completion — the realtime bus has no `command:executed` signal.
+
+## Critical missing pieces
+
+| Proposed command | Why it blocks | Effort | Depends on |
+|---|---|---|---|
+| `code/exists` | Cannot conditionally scaffold (`generate/module` would clobber or fail unpredictably without an existence probe) | Small | None — extend `FileEngine` |
+| `code/list` (flat readdir) | Persona must use full recursive `code/tree` to inspect a single directory; collision-detection during naming is O(workspace) | Small | None |
+| `code/glob` | No standalone glob expansion (only embedded in `code/search`'s `fileGlob` param). Cannot enumerate "all `*.rs` in modules/" before editing | Small | None |
+| `continuum-core/build` | Rust build feedback is raw stderr; persona cannot parse errors into structured form like TS gets | Medium | `code/shell/execute` (compose), cargo JSON output |
+| `continuum-core/test` | Same as build — no structured test result (count, failure names, timing). Iteration loop is opaque | Medium | Cargo's `--message-format=json` |
+| `events/command-completed` | `Stream` + `Lambda` cell shapes return runtime errors. No bus subscription for command lifecycle. Polling violates RTOS-brain doctrine | Large | Interceptor chain hook + Events primitive wiring |
+| `code/shell/stream` | `code/shell/watch` is blocking-poll only — incompatible with adaptive cadence loop | Medium | Stream cell shape implementation |
+| `code/move` | Non-blocking today but required for scaffold reorganization. (`code/delete` already exists at `modules/code.rs:205`; only `code/move` is genuinely absent.) | Small | `FileEngine` already has internal support |
+
+## Suggested next-sprint priorities
+
+**Ordered by leverage** — each one unblocks workflows that compose with the ones below it.
+
+### 1. `code/exists` + `code/list` + `code/glob` (bundled — Small)
+**Signature**: `code/exists({path}) -> {exists, kind}` · `code/list({path, includeHidden?}) -> {entries: DirEntry[]}` · `code/glob({pattern, root?}) -> {matches: string[]}`
+
+**Unblocks**: Safe self-scaffolding. Persona runs `code/exists` before `generate/module` to avoid collisions; `code/glob` to find candidate files; `code/list` for cheap directory inspection without the cost of full `code/tree`.
+
+**Composes**: Extend existing `FileEngine` in continuum-core. No new module needed — add three handlers to the file module (or scaffold a sibling `fs` module via `generate/module` itself — dogfooding).
+
+**Leverage/complexity**: Highest leverage, lowest cost. Three small handlers in a module that already exists.
+
+### 2. `continuum-core/build` + `continuum-core/test` (Medium)
+**Signature**: `continuum-core/build({package?, features?}) -> {success, errors: RustError[], warnings, duration}` · `continuum-core/test({package?, filter?, features?}) -> {passed, failed, ignored, failures: TestFailure[], duration}`
+
+**Unblocks**: Rust iteration loop with parity to TypeScript. Persona can scaffold a module, build it, parse compile errors, edit, retest — same feedback density Joel gets from `npm run build:ts`.
+
+**Composes**: New module scaffolded via `generate/module` (e.g., `cargo` module in continuum-core). Internally invokes `cargo` with `--message-format=json` and parses diagnostics. Could also live as TS commands wrapping `code/shell/execute`.
+
+**Leverage/complexity**: High leverage (Rust is the substrate). Medium complexity — cargo JSON parsing is well-trodden ground.
+
+### 3. `events/command-completed` event stream (Large but pivotal)
+**Signature**: `Events.subscribe('command:completed', ({commandName, executionId, success, durationMs}) => ...)` plus the dual `command:failed` channel.
+
+**Unblocks**: The RTOS-brain doctrine ("handlers read pre-staged results, never block"). Persona's autonomous loop currently violates this — it must `code/shell/watch` in a blocking poll, which freezes the inbox cadence. Event-driven completion lets `serviceInbox()` stay reactive.
+
+**Composes**: Hook into the interceptor chain (already landed in PRs #1486–#1499). Every CommandResponse emits an event before returning. No new module — extend the dispatcher.
+
+**Leverage/complexity**: Highest architectural leverage. Larger because it touches the dispatch hot path; needs care around the per-resource lock doctrine.
+
+### 4. `code/shell/stream` (Medium)
+**Signature**: `code/shell/stream({executionId}) -> Stream<ClassifiedLine>` — returns the Stream cell shape (currently reserved, returns runtime error).
+
+**Unblocks**: Long-running build/test output as a true stream, not a poll loop. Activates the Stream cell shape that's already in the CommandResult enum.
+
+**Composes**: Extend `code/shell/execute` module. Forces Stream cell shape implementation — pays the architectural debt of a reserved-but-unimplemented variant.
+
+### 5. `code/move` (Small)
+**Signature**: `code/move({from, to}) -> {moved}`
+
+**Unblocks**: Module reorganization (rename a scaffolded module dir, move files between subtrees). Not blocking today but rounds out the file CRUD surface.
+
+**Note**: `code/delete` already exists at `modules/code.rs:205` — initial gap-report scan missed it. Only `code/move` is genuinely absent.
+
+## Alignment with the three-primitive doctrine
+
+| Proposal | Primitive | Why it earns its place |
+|---|---|---|
+| `code/exists` / `list` / `glob` | **Commands** | Pure request/response queries against `FileEngine`. No state, no subscription. Textbook Commands. |
+| `continuum-core/build` / `test` | **Commands** | Request/response with structured result. Each invocation is a discrete unit returning a typed envelope. |
+| `events/command-completed` | **Events** | This is the missing publish/subscribe surface for the dispatch loop. It serves Events specifically because polling-for-result violates the RTOS doctrine of "never block on the hot path." |
+| `code/shell/stream` | **Commands** (returning Stream cell) | The Stream cell shape is a Commands return variant — this implementation activates it. Personas consume the stream like an iterator, not as a subscription. |
+| `code/move` | **Commands** | Mutating request/response. Could optionally emit `data:file:moved` events (Events surface) for sentinel observers. |
+| Persona-side composition | **Persona** | The autonomous loop in `serviceInbox()` is where all of the above compose into self-coding behavior. No new Persona primitives — the existing convergence pattern (inbox + state + genome) handles it. |
+
+## Connection to the "later parts" of the vision
+
+**Intra-grid groundwork**: `continuum-core/build` and `continuum-core/test` are the cleanest seeds for grid-routed sharing. Once a build/test result is a structured envelope (not raw stderr), it's trivially serializable across the grid — a persona on an M-series Mac can run `continuum-core/test` against a module a persona on a peer's RTX 5090 just authored, and the result envelope travels back on the same Commands/Events bus. Same for a future `code/git` family (`code/git/commit`, `code/git/diff`, `code/git/branch`) — once those exist as structured commands, they compose with airc's mesh routing without modification. The substrate already routes commands across peers; what's missing is the command surface to route.
+
+**Cooperation incentive structure**: This is the deepest alignment claim, and it's already laid down in [`GENOME-FOUNDRY-SENTINEL.md`](../architecture/GENOME-FOUNDRY-SENTINEL.md). The tiered genome cache (L1–L5) plus foundry-as-JIT means a module a persona authors and tests successfully becomes an artifact in the shared economy — other personas pull it from the cache instead of re-deriving it, paying the original author with cache-hit attribution. The same `generate/module` scaffold that unblocks self-coding is the upstream of artifacts that the foundry economy distributes. Hoarding a working module costs the hoarder cache misses on their own future requests for adjacent functionality; sharing it earns attribution and reciprocal access. The economics are structural, not policy — which is the only kind of alignment that scales. The proposed `events/command-completed` surface is what makes attribution observable in real time, closing the loop from *"I built this"* to *"the grid knows I built this and routes credit accordingly."*
+
+## Methodology
+
+This report is the synthesis of a 4-agent multi-thread workflow (`w14iiocs7`):
+
+- **3 parallel survey agents** (file ops / build+test / observability) — each scanned `src/commands/`, `core/continuum-core/src/modules/`, and `docs/architecture/MODULE-CATALOG.md` and returned structured `{existing_commands, missing_commands, summary}` JSON
+- **1 synthesis agent** — combined the three surveys with the doctrine (three primitives + alignment economics) into this report
+
+Raw survey data lives in the workflow's transcript directory; this document is the canonical artifact. Update it when new commands land in the substrate (turning a `missing` row into an `existing` row) or when the priority ordering shifts based on the next phase of work.

-# Sentinel Gap Analysis — Competitive Position
-
-> What we have, what we lack, and what to build next — compared against 10 competing agentic coding tools and current distillation research.
-
-**Status:** 2026-02-28
-**Parent:** [Sentinel README](README.md)
-
-## Executive Summary
-
-Our sentinel system is architecturally **more ambitious** than any single competitor — we combine pipeline orchestration, LoRA training, multi-agent coordination, and persona cognition in one system. But the field has leapfrogged us in several critical areas: **context management**, **codebase understanding**, **developer UX**, and **production multi-agent execution**. Our unique advantage — the LoRA distillation pipeline — exists in prototype but needs hardening.
-
-The strategic play: **don't compete on agent UX** (Claude Code, Cursor already won that). Instead, **use external agents as teachers** and distill their expertise into our personas via LoRA. Sentinels orchestrate this entire lifecycle.
-
----
-
-## What We Have (Strengths)
-
-### 1. Pipeline Composition Engine (Rust) — Unique
-10 step types (Shell, LLM, Command, Condition, Loop, Parallel, Emit, Watch, Sentinel, CodingAgent) with 103 tests. No competitor has anything close to this. Claude Code has subagents but they're flat — no loops, conditions, parallel branches, or inter-agent events. Our pipelines are **JSON-serializable data** that personas can create, save, share, and modify.
-
-### 2. LoRA Training Pipeline — Unique
-End-to-end proven: train (PEFT) → discover (AdapterStore) → load (Candle) → merge → inference. No competitor does any form of learning or adaptation beyond configuration files. This is our moat.
-
-### 3. Academy Dual-Sentinel Architecture — Unique
-Teacher synthesizes training data, student trains and gets examined. No competitor has anything like autonomous curriculum design + examination + LoRA training in one orchestrated system.
-
-### 4. Training Data Capture from Coding Agents — Unique
-`SentinelCodingAgentServerCommand.captureTrainingData()` already extracts user→assistant interaction pairs from coding agent sessions and feeds them to `GenomeCaptureInteraction.execute()` with quality scores (0.9 success, 0.3 failure). This is the foundation for distillation.
-
-### 5. Persona Ownership & Escalation — Unique
-Every sentinel has `parentPersonaId`. Results flow to the persona's inbox via `SentinelEscalationService`. Execution history persists as memory. No competitor ties agent results to a persistent identity with memory.
-
-### 6. Event-Based Inter-Agent Communication — Unique
-`Emit`/`Watch` steps enable multi-sentinel coordination (teacher↔student). Cursor has parallel agents but they don't coordinate — they work independently on separate files.
-
----
-
-## What We Lack (Gaps)
-
-### GAP 1: Codebase Understanding (Critical)
-
-**The field:**
-- **Aider**: PersonalizedPageRank on tree-sitter dependency graph. Builds a `NetworkX MultiDiGraph` of file relationships, ranks using PageRank personalized to the active chat files. Compresses entire codebase structure into a token-budget-constrained repo map.
-- **Cursor**: Custom embedding model indexes entire codebase into Turbopuffer vector DB. Sub-100ms lookup after initial indexing.
-- **Sweep**: CST (Concrete Syntax Tree) entity extraction. Processes 2M+ files/day. Prunes each file to only the entities needed.
-- **OpenCode**: Native LSP integration for 20+ languages. Diagnostics as a first-class tool.
-
-**Our system:** No codebase indexing. No repo map. No tree-sitter. No LSP. When a sentinel runs a CodingAgent step, the agent (Claude Code) does its own codebase exploration, but our system doesn't benefit from it. Each sentinel invocation starts blind.
-
-**Impact:** Our personas can't reason about code structure. They can't say "this change affects these 5 files" without re-exploring every time. The Academy teacher can't automatically identify the right source files for curriculum design.
-
-**Recommendation:** Build a `CodebaseIndex` service (Rust worker) that:
-- Uses tree-sitter to extract symbols from all source files
-- Builds a dependency graph (imports, function calls, type references)
-- Exposes via a sentinel Command step: `codebase/symbols`, `codebase/dependencies`, `codebase/search-semantic`
-- Incrementally updates on file changes (watch filesystem)
-- This is the `fastembed` + `ort` infrastructure we already have — wire it up
-
-### GAP 2: Context Management (Critical)
-
-**The field:**
-- **GSD**: Explicitly solves "context rot" — quality degrades as context fills. Forces work into small specs, each running in a fresh 200k context window. Atomic git commits per task.
-- **Cline**: Memory Bank (persistent project knowledge), Focus Chain (auto-generated todo list preventing drift), Auto-Compact (summarizes at capacity), .clinerules (declarative context management rules).
-- **Claude Code**: Auto-compaction at 95% capacity. CLAUDE.md for persistent instructions. Session forking for exploration.
-- **Codex**: Progressive skill disclosure — loads metadata first, full content only when needed.
-
-**Our system:** No context management for sentinel LLM steps. An LLM step gets whatever prompt we give it — no awareness of codebase structure, no persistent memory across pipeline iterations, no progressive disclosure. Long-running pipelines (Academy sessions can last hours) will hit context limits.
-
-**Impact:** Academy teacher LLM steps that analyze code, design curriculum, and generate training data are all limited to whatever we manually stuff into the prompt. No automatic context enrichment.
-
-**Recommendation:**
-- Add a `contextSources` field to LLM steps that auto-fetches codebase context
-- Integrate the CodebaseIndex from GAP 1 so LLM steps can reference `{{codebase.symbols.relevant}}` or `{{codebase.dependencies.for_file}}`
-- For long pipelines, implement step-result summarization to keep context fresh
-- RAG integration for LLM steps — we already have the RAG pipeline, just wire it to sentinel LLM steps
-
-### GAP 3: Multi-Agent Isolation & Parallelism (Important)
-
-**The field:**
-- **Cursor**: Up to 8 agents simultaneously in **git worktrees**. Each gets an isolated copy of the repo. Background agents run in **cloud VMs** — truly asynchronous. 35% of Cursor's PRs are agent-authored.
-- **Codex**: OS-level **Landlock + seccomp** sandboxing. Network disabled during execution. Sub-agents inherit sandbox policy.
-- **OpenHands**: Docker-sandboxed execution with bash + browser + IPython. Hierarchical agent delegation via AgentHub registry.
-
-**Our system:** `maxConcurrentSentinels = 4` in Rust, but no isolation between them. No sandboxing. No worktree isolation. No network restrictions. CodingAgent steps run in the host environment — a malicious or buggy agent could damage the workspace.
-
-**Impact:** We can't safely run multiple coding agents in parallel on the same codebase. We can't run untrusted pipelines. We can't scale beyond one machine.
-
-**Recommendation:**
-- **Phase 1**: Git worktree isolation for CodingAgent steps (create worktree → run agent → merge back). This is what Cursor does.
-- **Phase 2**: Docker container isolation for shell/coding-agent steps. This is what SWE-agent and OpenHands do.
-- **Phase 3**: Remote execution — sentinels that run on different machines (the P2P mesh concept).
-
-### GAP 4: Agent UX & Developer Experience (Important)
-
-**The field:**
-- **Claude Code**: Hooks (PreToolUse, PostToolUse), CLAUDE.md, auto-memory, session forking, ToolSearch meta-tool
-- **OpenCode**: LSP integration, SSE events for multi-client sync, Tauri desktop + TUI
-- **Cline**: Plan/Act mode separation, Focus Chain, checkpoint system, Memory Bank
-
-**Our system:** `./jtag sentinel/run` returns a handle. `./jtag sentinel/status --handle=xxx` polls. `./jtag sentinel/logs/tail --handle=xxx` reads logs. Functional but spartan. No real-time streaming to the UI. No planning mode. No interactive approval during execution.
-
-**Impact:** Developers (including our AI personas) can't easily watch sentinel progress, intervene mid-execution, or adjust course. The SentinelEventBridge polls at 1s intervals but the UI doesn't consume these events well.
-
-**Recommendation:**
-- Wire SentinelEventBridge events to the chat widget (sentinels report progress as chat messages)
-- Add a `sentinel-monitor` widget that shows live pipeline execution (step by step, with outputs)
-- Add interactive approval steps: a new `Approve` step type that pauses and waits for human/persona approval before proceeding
-
-### GAP 5: Quality Scoring & Evaluation (Important)
-
-**The field:**
-- **NVIDIA Data Flywheel**: Run teacher → capture traces → filter by quality → train student → evaluate → promote if quality meets threshold → repeat
-- **Agent-FLAN**: Decomposed training data into capability categories + negative samples to reduce hallucination
-- **LoRA Soups / LoRAtorio**: Optimal adapter merging with weighted composition
-
-**Our system:** Binary quality scoring (0.9 success, 0.3 failure) in `captureTrainingData()`. No evaluation after training. No adapter benchmarking. No negative examples. No composite quality metrics.
-
-**Impact:** We're training on poorly-scored data and never validating that the trained adapter actually improved. The flywheel can't spin if we can't measure progress.
-
-**Recommendation:**
-- Implement composite quality scoring:
-  ```
-  TraceQualityScore {
-    outcome: 0-1      // did it succeed?
-    correctness: 0-1   // does code compile/pass tests?
-    efficiency: 0-1    // steps vs optimal
-    complexity: 0-1    // task difficulty
-    novelty: 0-1       // different from existing data
-    composite() → weighted sum
-  }
-  ```
-- Add a `BenchmarkSentinel` that tests adapters after training on held-out tasks
-- Auto-rollback if new adapter performs worse than previous version
-- Include negative examples (failed traces with corrections) in training data
-
-### GAP 6: Multi-Provider Agent Support (Medium)
-
-**The field:**
-- **Aider**: Works with literally any model. No tool-use required — uses edit formats parsed from text.
-- **OpenCode**: 75+ LLM providers through AI SDK
-- **Cline**: Multi-model with per-task model selection
-
-**Our system:** CodingAgentRegistry has only `ClaudeCodeProvider`. The interface supports multiple providers but only one is implemented.
-
-**Impact:** We can't distill from multiple teacher agents. Multi-teacher distillation research shows that diverse teachers produce more robust students.
-
-**Recommendation:**
-- Implement `CodexProvider` (OpenAI Codex CLI — 96% Rust, has an SDK)
-- Implement `AiderProvider` (Python, subprocess-based)
-- Implement `OpenCodeProvider` (TypeScript/Bun, has SDK)
-- Each provider captures interactions in the same `CodingAgentInteraction` format
-- Multi-teacher training pipeline merges traces from all providers
-
-### GAP 7: Persona-Sentinel Integration Depth (Medium)
-
-**The field:** N/A — no competitor has personas. This is purely about our own integration depth.
-
-**Our current state:** Sentinels are **adjacent** to personas, not **part of** them:
-- PersonaUser receives `InboxTask` from sentinel escalation (reactive)
-- PersonaUser can dispatch sentinels via tool calls (manual)
-- No automatic sentinel creation based on persona cognition
-- No sentinel memories feeding back into persona RAG context
-- Personas don't create their own sentinels autonomously
-
-**The user's vision:** "personas using sentinels as part of their own being, like any command, for anything"
-
-**Impact:** Sentinels feel like external tools personas invoke, not integrated capabilities. A persona should be able to think "I need to learn TypeScript testing" and autonomously spawn an Academy session, or think "this code needs reviewing" and spawn a review sentinel, without explicit human instruction.
-
-**Recommendation:**
-- Add sentinel dispatch to PersonaUser's autonomous task generation (`generateSelfTasks()`)
-- Sentinel execution memories should be injected into persona RAG context
-- Personas should be able to create pipeline definitions from natural language (LLM step → JSON pipeline)
-- Sentinel templates stored per-persona in their longterm.db

-## Conclusion
-
-Our system is architecturally positioned at the intersection that the entire field is converging toward: **agents that learn**. Every competitor is a better coding agent than our sentinels. But none of them learn. None of them have persistent identity. None of them train LoRA adapters from their own sessions. None of them have autonomous curriculum design.
-
-The strategy is clear:
-1. **Use the best agents as teachers** (Claude Code, Codex, Aider)
-2. **Capture their expertise as training data** (interaction traces with quality scores)
-3. **Train local personas via LoRA** (the distillation flywheel)
-4. **Evaluate and iterate** (benchmark sentinels, auto-rollback)
-5. **Make sentinels a natural extension of persona cognition** (autonomous dispatch, memory integration)
-
-The field builds better hammers. We're building the blacksmith.

+/**
+ * Typed reference to state owned by a specific module.
+ *
+ * # Round-trip
+ *
+ * 1. Producer command (e.g., `chat/send`) creates internal state
+ *    (a message buffer, a session, a render context). It allocates a
+ *    handle ID, stores the state under that ID in its own state map,
+ *    and returns `CommandResult::Handle(HandleRef { owner: "chat",
+ *    id, type_tag: "chat::MessageHandle", created_at_ms })`.
+ *
+ * 2. Caller (Rust, TS, or remote) holds the HandleRef opaquely. It
+ *    serializes through any wire crossing (it's plain JSON via serde).
+ *
+ * 3. Caller invokes a downstream command that takes the handle:
+ *    `Commands.execute("chat/message/get", { handle })`. The kernel
+ *    routes to the chat module (`chat/` prefix in the registry); the
+ *    chat module reads the handle's `id` from params and looks up its
+ *    state map.
+ *
+ * 4. Cross-module: if a different module needs to operate on the
+ *    handle's underlying state, it asks the owner via a command:
+ *    `Commands.execute("chat/message/get", { handle })` — same call,
+ *    routed to the owner. The kernel doesn't care which module asked.
+ *
+ * # `type_tag` discipline
+ *
+ * Convention: `"<module>::<TypeName>"` matching the Rust type that
+ * produced the handle. e.g., `"chat::MessageHandle"`, `"rag::Slice"`,
+ * `"persona::InboxFrame"`. Lets typed callers cast safely on receipt
+ * without round-tripping through the producer.
+ *
+ * # Lifetime
+ *
+ * Producer owns the lifetime. The handle is valid as long as the
+ * producer's state map holds the ID. Producers may evict handles
+ * after a TTL, on session end, on resource pressure, etc. A consumer
+ * holding a stale handle gets a typed error from the producer's
+ * command handler (`"handle not found"`); the kernel doesn't
+ * participate in lifetime management. This is intentional — the
+ * kernel stays minimal, and lifetime policy belongs to the producer.
+ *
+ * # Cross-machine
+ *
+ * Same primitive. A handle minted on machine A is meaningful only on
+ * machine A. If a consumer on machine B calls a command taking that
+ * handle, the kernel's grid interceptor routes the call back to A
+ * (the handle's `owner` lives there). The handle ID never leaves A's
+ * state map; the remote call carries the ID, A executes the op
+ * locally, returns the result.

+#
+# TRADE-OFFS (cargo target lock is real):
+#   - Sequential builds: concurrent `cargo build` calls across
+#     worktrees serialize on the target lock. Invisible for the
+#     typical one-PR-at-a-time flow.
+#   - Branch-switch rebuilds when Cargo.lock differs.
+#   - Composes with slice 1 (sccache) + slice 2 (linker selection).
+#
+# WHAT THIS SCRIPT DOES:
+#   1. Creates ~/.airc/cargo-target/ if missing.
+#   2. Writes a one-line CARGO_TARGET_DIR export into the user's
+#      shell init (zshrc / bashrc — auto-detected).
+#   3. Reports current usage (before/after).
+#
+# WHAT THIS SCRIPT DOES NOT DO:
+#   - Edit core/.cargo/config.toml (that's checked-in opt-in
+#     guidance; not a per-machine action).
+#   - Delete existing per-worktree target/ dirs (operator decision;
+#     see the optional cleanup step below).
+#   - Sync sccache settings (slice 1 has its own opt-in).

+# canary-smoke-airc-queue.sh — AIRC + queue-lifecycle slice of the canary
+# end-to-end smoke matrix (continuum#1132 PR-1).
+#
+# WHY THIS GATE EXISTS
+#
+# Alpha confidence requires more than compile checks. cmd_queue.sh shipped
+# six verbs in seven days (airc#566/#568/#573/#574/#583/#581) — the dispatch
+# table, help text, dry-run paths, and envelope shapes drift the moment
+# nobody re-exercises the CLI surface. This script is the canary check that
+# catches drift early instead of letting it land in a peer's bash session.
+#
+# WHAT IT VALIDATES (PR-1 SCOPE — AIRC + queue subset only)
+#
+#   1. `airc` is on PATH and answers --version (binary present).
+#   2. `airc queue --help` lists every documented verb the dispatch table
+#      claims (catches: dispatcher and help drift apart, e.g. PR-2 forgot
+#      to register `claim` in --help).
+#   3. `airc queue add owner/repo --title X --dry-run` emits a card body
+#      with `kind: "airc-queue-card-v1"` (catches: envelope schema drift).
+#   4. `airc queue claim owner/repo#1 --dry-run` emits a status-log entry
+#      (catches: mutate-card path silently drops log entries).
+#   5. `airc queue set-status owner/repo#1 review --dry-run` shows the
+#      enum-validated state transition (catches: enum guard regresses).
+#   6. `airc queue close-merged <fake-pr-url> --dry-run` parses the PR ref
+#      shape and emits the would-close summary (catches: airc#576 ref
+#      parser regresses).
+#
+# OTHER SLICES OUT OF SCOPE — handed to peers in their territory:
+#   - Cargo + features parity (sibling/codex)
+#   - JTAG ping/screenshot (anyone with a running stack)
+#   - Persona/chat path proof (anyone with personas seeded)
+#   - ts-rs export sync ratchet (sibling tab #1, continuum#1132 PR-2)
+#   - Docker/Carl install gate (already lives at carl-install-smoke.sh)

+# canary-smoke-jtag.sh — JTAG ping + screenshot slice of the canary
+# end-to-end smoke matrix (continuum#1132).
+#
+# WHY THIS GATE EXISTS
+#
+# The user-facing surface — what Carl actually opens after install — is
+# only as good as the JTAG CLI's ability to talk to the running stack
+# AND the widget DOM's ability to render. Both have failed silently
+# in production: the global `jtag` shim has been observed pointing at
+# a deleted temp dir from a prior install (issue #91-#93), and the
+# screenshot path can return 200 with a blank page when the widget
+# server is up but the bundle is stale.
+#
+# This slice catches both: (1) jtag CLI invokable; (2) jtag → running
+# stack roundtrip works (ping); (3) screenshot writes a non-empty file
+# that's a valid PNG.
+#
+# WHAT IT VALIDATES
+#
+#   1. jtag binary is on PATH (or ./src/jtag exists in this repo).
+#      File-system check only — JTAG CLI requires the running stack
+#      even for `--help`, so an invocation-based liveness probe is
+#      indistinguishable from a stack-down skip.
+#   2. Stack is reachable: `jtag ping` returns success. Catches:
+#      stack not running; widget-server crashed; UnixSocket gone;
+#      AND the dangling-shim regression class (#91-#93) where the
+#      shim resolves but invocation fails with ERR_MODULE_NOT_FOUND.
+#   3. Screenshot writes a non-empty PNG: `jtag interface/screenshot
+#      --filename TMP.png` produces > 1KB file with PNG magic bytes.
+#      Catches: screenshot returns 200 but body is empty/blank.
+#
+# When the stack is DOWN (no continuum-core process), steps 2-3 SKIP
+# with a clear message — operator can run `npm start` to enable.

+# install.sh has a `compose pull 2>/dev/null || warn ... will build locally`
+# fallback so end users on uncommon architectures (e.g. ports to future
+# phone targets) still have a path. CI must NOT take that fallback —
+# building continuum-core-vulkan from source on the no-GPU GHA runner
+# is a full cargo build --release that takes 25+ minutes and hits
+# CARL_INSTALL_TIMEOUT_SEC, which is exactly the silent downgrade
+# Joel called out 2026-05-30 ("Relying on stale builds is dumb" /
+# "fix properly. What broke, what is the long term goal").
+#
+# What broke (concrete): PR #1476 (avatars context fix) fixed the
+# `docker compose build` error; install.sh then proceeded to
+# `compose pull` which failed (pr-1476 image hadn't been pushed via
+# scripts/push-current-arch.sh), and silently fell through to
+# `compose up` → docker build → cargo build --release → 25min
+# timeout. The avatars fix WORKED; the deeper issue is the silent
+# downgrade after pull failure.
+#
+# Long-term goal: every PR's install-smoke tests THIS PR's binary,
+# fast and reliably. That requires the pre-built image to exist
+# (dev pre-push pipeline publishes pr-N). When the publish didn't
+# happen, the smoke should fail LOUDLY ("image missing, push via
+# scripts/push-current-arch.sh") instead of silently slipping into
+# a 25-min build that times out OR worse, silently using a stale
+# canary image and reporting "tests pass!" on someone else's binary.
+#
+# Only the HEAVY Rust binary image (continuum-core-vulkan) must exist
+# pre-built — that's the one whose local build is a 25-min cargo
+# build --release that hits CARL_INSTALL_TIMEOUT_SEC. The lighter TS
+# images (node-server, widget-server, model-init) build in under a
+# minute on either arch per Joel 2026-05-30 — install.sh's fallback
+# building them locally is acceptable, doesn't blow the timeout.
+#
+# This split avoids the precheck mis-firing on the common case where
+# canary has the Rust image fresh (BigMama pushed) but the lighter
+# TS sidecar images haven't been pushed yet under the canary tag.
+# Just the Rust image being present is sufficient to make the smoke
+# fast and meaningful.
+#
+# CONTINUUM_IMAGE_TAG comes from the workflow (canary by default
+# per the carl-install-smoke.yml change in this commit). Operator
+# escape hatch: CARL_ALLOW_LOCAL_BUILD=1 opts into install.sh's
+# full fallback — useful when explicitly debugging the heavy build

+# Persona TypeScript Cognition Ratchet — Lane F
+
+Mechanical gate that prevents the persona-cognition TypeScript layer from
+growing while the Rust runtime takes over. See
+[`docs/planning/ALPHA-GAP-ANALYSIS.md`](../../docs/planning/ALPHA-GAP-ANALYSIS.md)
+§"Lane F: TS Cognition Deletion Ratchet" for the design rationale.
+
+This is Lane F **PR-1** — the local script. PR-2 (`persona-ts-ratchet-ci`)
+will wire it into `pre-push` and CI. PR-3 (`forbidden-provider-scan`) adds
+deprecated-provider/fallback-comment scanning on top.
+
+## What it checks
+
+Two ratchets, both enforced together:
+
+1. **LOC ratchet** — total `.ts` line count under each watched cognition
+   directory must not exceed its committed baseline.
+2. **New-file ratchet** — any new `.ts` file appearing under a watched
+   directory must either be in the baseline file-set OR match a glob in
+   the allowlist.
+
+The ratchet only moves down. After legitimate TS deletion lands, refresh
+the baseline (next section) so future PRs can't silently regrow.
+
+## Watched directories
+
+- `src/system/user/server/modules/cognition`
+- `src/system/user/server/modules/cognitive`
+- `src/system/user/server/modules/consciousness`
+- `src/system/user/server/modules/being`
+- `src/system/user/server/modules/central-nervous-system`
+- `src/system/user/server/attention`
+- `src/system/ai/server`
+
+## Usage
+
+```bash
+# Check — fails the build if the ratchet is violated. CI mode.
+scripts/ratchet/persona-ts-ratchet.sh check
+
+# Refresh — regenerate the baseline after legitimate TS deletion.
+# Commit the updated persona-ts-baseline.txt with your deletion PR.
+scripts/ratchet/persona-ts-ratchet.sh refresh
+
+# Run the test suite.
+scripts/ratchet/test-persona-ts-ratchet.sh
+```
+
+## Allowlist
+
+`persona-ts-allowlist.txt` holds path-globs for the categories of TypeScript
+that ARE allowed to land in cognition directories (without burning ratchet
+budget on the new-file count):
+
+- Generated artifacts (`**/*.generated.ts`, `**/*.gen.ts`, `**/generated/**`)
+- Type-only files (`**/*.types.ts`)
+- Schemas (`**/*.schema.ts`, `**/schemas/**`)
+
+Allowlist matches do NOT exempt the file from the LOC ratchet — they only
+exempt it from the new-file ratchet. A new generated file still counts
+toward LOC; if its addition pushes a directory above its baseline LOC,
+the ratchet fails. That's deliberate: the lane is a deletion lane, not a
+generated-bloat lane.
+
+## When the ratchet fails
+
+The script emits the specific violations and three options:
+
+1. Move the new behavior into Rust (the lane's goal).
+2. If the file is genuinely generated / a schema / a UI type, add a
+   path-glob for it to `persona-ts-allowlist.txt`.
+3. If you deleted TS, run `refresh` and commit the new baseline.
+
+## Why Bash, not Rust
+
+This ratchet is build infrastructure, not runtime behavior. The
+[Lane F design](../../docs/planning/ALPHA-GAP-ANALYSIS.md) targets runtime
+cognition migration. Build tooling (this script, `git-prepush.sh`,
+`main-promotion-gate.sh`) lives in shell because it runs outside the
+runtime and shell is the standard tool. The thing being enforced — that
+runtime logic must be Rust — is separate from the enforcer's language.

+# sdk/ — per-language SDKs over `client/continuum-client`
+
+Language wrappers that bridge `client/continuum-client` (rust) to the
+native ecosystem of each platform. CBAR-style: one shared core, N
+language frontends, mirrored API surface.
+
+| SDK | Bridge | Consumed by |
+|-----|--------|-------------|
+| `typescript/` | hand-written (today); flutter_rust_bridge alt later | `apps/web`, `apps/desktop` (Tauri), `apps/mcp` (Node MCP server) |
+| `flutter/` | `flutter_rust_bridge` — Dart over rust FFI | `apps/mobile`, `apps/ar`, `apps/vr` |
+| `swift/` | `swift-bridge` — Swift package | native iOS apps (when Flutter isn't enough) |
+| `kotlin/` | `uniffi` — `.aar` artifact | native Android apps |
+
+Each SDK's job is to give the platform's developers an idiomatic API
+shape (Dart streams, Swift async/await, Kotlin coroutines) over the
+same `Connection / CommandClient / EventSubscriber` primitives the rust
+client exposes. The substrate stays oblivious to language.

+# sdk/flutter — Dart SDK over `client/continuum-client` (placeholder)

+## Intent
+
+Dart package that wraps `client/continuum-client` (rust) for Flutter
+consumers. `flutter_rust_bridge` reads rust source and generates the
+Dart↔Rust FFI glue; the resulting Dart API mirrors the rust client's
+`Connection / CommandClient / EventSubscriber` primitives but with
+Dart idioms (`Stream<T>`, `async` / `await`).
+
+When this lands:
+- `sdk/flutter/pubspec.yaml` declares the pub.dev package.
+- `sdk/flutter/rust/Cargo.toml` is a thin rust crate that re-exports
+  `client/continuum-client` + adds `#[frb]` annotations for codegen.
+- `sdk/flutter/lib/continuum.dart` is the consumer-facing Dart API.
+
+Consumed by `apps/mobile`, `apps/ar`, `apps/vr` (any platform Flutter
+can build for).

+
+Consumed by native Android apps (Quest VR + traditional phones).

 /**
- * AI Generate Command - Server Implementation
- * ============================================
+ * AI Generate Command - Server Implementation (thin shim)
+ * =======================================================
  *
- * Server-side AI generation with RAG context building
- * All database access and LLM calls happen here
+ * Rust owns response generation: prompt assembly (system prompt +
+ * history + time prefixes + hour-gap markers + identity reminder),
+ * provider selection, admission gating, timeout, and token-usage
+ * stamping all live in `cognition/generate_response.rs`. This shim:
+ *
+ *   1. Builds the RAG context server-side (still TS — the
+ *      `ChatRAGBuilder` factory + entity reads have not been ported
+ *      to Rust yet; tracked separately).
+ *   2. Adapts the RAG context onto `AIDecisionContext` and hands off
+ *      to `AIDecisionService.generateResponse`, which is the proven
+ *      IPC seam already used by PersonaUser's response path.
+ *   3. Translates the Rust result back to `AIGenerateResult`.
+ *
+ * Direct-message and preview modes remain TS-side because they are
+ * introspection/test paths that bypass admission and provider
+ * selection — Rust intentionally does not expose a "skip the gate"
+ * code path.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag ai/key/diff --localEntries='[...]' --remoteEntries='[...]' --targetNode=windows-rtx
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('ai/key/diff', {
+  localEntries,
+  remoteEntries,
+  targetNode: 'windows-rtx',
+});
+```
+
+## Parameters
+
+- **localEntries** (required): `array` - Local redacted ai/key/status entries.
+- **remoteEntries** (required): `array` - Remote redacted ai/key/status entries from a trusted target node.
+- **targetNode** (optional): `string` - Optional target node id or name for merge-plan labels.
+
+## Result
+
+Returns `AiKeyDiffResult` with:
+
+Returns CommandResult with:
+- **mergePlanId**: `string` - Stable id for this value-free merge plan.
+- **actions**: `array` - Merge actions containing provider/key/action/reason/fingerprint metadata only.
+- **conflictCount**: `number` - Number of conflicts requiring owner approval.
+- **actionCount**: `number` - Number of generated actions.
+
+## Examples
+
+### Compare local and remote redacted key states
+
+```bash
+./jtag ai/key/diff --localEntries='[...]' --remoteEntries='[...]' --targetNode=windows-rtx
+```
+
+**Expected result:**
+{ success: true, actionCount: 1, conflictCount: 0 }
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help ai/key/diff
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'ai/key/diff'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme ai/key/diff
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'ai/key/diff'
+```
+
+## Testing
+
+### Unit Tests
+
+Test value-free merge-plan behavior without server dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/ai/key/diff/test/unit/AiKeyDiffCommand.test.ts
+```
+
+**What's tested:**
+- Same redacted fingerprints produce no-op actions
+- Missing remote/local keys produce explicit copy-plan actions
+- Different configured fingerprints produce conflicts
+- Missing keys on both sides are omitted
+- Merge plan ids are deterministic across input ordering
+- Results never serialize raw secret values
+
+### Integration Tests
+
+Smoke-test the shared params/result factories:
+
+```bash
+npx tsx commands/ai/key/diff/test/integration/AiKeyDiffIntegration.test.ts
+```
+
+**What's tested:**
+- Factory preservation of local/remote status arrays
+- Default empty merge-plan fields
+
+## Access Level
+
+**owner-only** - This command compares redacted key metadata for trusted grid reconciliation.
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AiKeyDiffPlanner.ts`
+- **Browser**: Browser-specific implementation in `browser/AiKeyDiffBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AiKeyDiffServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/AiKeyDiffCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/AiKeyDiffIntegration.test.ts`

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag ai/key/status [options]
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('ai/key/status', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+- **provider** (optional): `string` - Optional provider name or config key. Omit to list all known keys.
+
+## Result
+
+Returns `AiKeyStatusResult` with:
+
+Returns CommandResult with:
+- **entries**: `array` - Redacted key status entries containing provider names, config key names, booleans, source, and short fingerprints only.
+- **configuredCount**: `number` - Number of configured keys.
+- **totalCount**: `number` - Number of checked keys.
+
+## Examples
+
+### List all known AI key statuses
+
+```bash
+./jtag ai/key/status
+```
+
+**Expected result:**
+{ success: true, configuredCount: 1, totalCount: 11 }
+
+### Check one provider by config key
+
+```bash
+./jtag ai/key/status --provider=OPENAI_API_KEY
+```
+
+**Expected result:**
+{ success: true, configuredCount: 1, totalCount: 1 }
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help ai/key/status
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'ai/key/status'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme ai/key/status
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'ai/key/status'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Ai Key Status/test/unit/AiKeyStatusCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Ai Key Status/test/integration/AiKeyStatusIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**owner-only** - Unknown access level
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AiKeyStatusTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/AiKeyStatusBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AiKeyStatusServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/AiKeyStatusCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/AiKeyStatusIntegration.test.ts`

+# Ai Local Inference Start Command
+
+Ensure Continuum's local inference HTTP server is running and return its URL. Idempotent — if already running, returns the existing URL without restarting. External agents (Claude Code via ANTHROPIC_BASE_URL, future Codex via OPENAI_BASE_URL) should call this once at startup, then use the returned URL.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag ai/local-inference/start 
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('ai/local-inference/start', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+No parameters required.
+
+## Result
+
+Returns `AiLocalInferenceStartResult` with:
+
+Returns CommandResult with:
+- **url**: `string` - Base URL where the local inference server is accepting requests (e.g., http://127.0.0.1:8421)
+- **port**: `number` - TCP port the server is bound to
+- **protocol**: `string` - Wire protocol the server speaks. Currently always 'anthropic' (Messages API).
+- **alreadyRunning**: `boolean` - True if the server was already up before this call (no spawn happened); false if this call started it
+
+## Examples
+
+### Start local inference (idempotent)
+
+```bash
+undefined
+```
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help ai/local-inference/start
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'ai/local-inference/start'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme ai/local-inference/start
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'ai/local-inference/start'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Ai Local Inference Start/test/unit/AiLocalInferenceStartCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Ai Local Inference Start/test/integration/AiLocalInferenceStartIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AiLocalInferenceStartTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/AiLocalInferenceStartBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AiLocalInferenceStartServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/AiLocalInferenceStartCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/AiLocalInferenceStartIntegration.test.ts`

+# Ai Local Inference Status Command
+
+Query Continuum's local inference HTTP server (Anthropic-compatible Messages API). Returns whether the server is running and the URL external agents (Claude Code via ANTHROPIC_BASE_URL, future Codex via OPENAI_BASE_URL) should point at to use local Continuum models instead of cloud APIs. First-class surface for the AGENT-BACKBONE integration story (PR #976 §1-§4).

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag ai/local-inference/status 
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('ai/local-inference/status', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+No parameters required.
+
+## Result
+
+Returns `AiLocalInferenceStatusResult` with:
+
+Returns CommandResult with:
+- **running**: `boolean` - True if the local inference HTTP server is bound + accepting requests
+- **url**: `string` - Base URL to use for external-agent ANTHROPIC_BASE_URL injection (e.g., http://127.0.0.1:8421). Empty when running=false.
+- **port**: `number` - TCP port the server is bound to. 0 when running=false.
+- **protocol**: `string` - Wire protocol the server speaks. Currently always 'anthropic' (Messages API). 'openai' will be added when openai_compat.rs lands per AGENT-BACKBONE §4.1.
+
+## Examples
+
+### Check if local inference is up
+
+```bash
+undefined
+```
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help ai/local-inference/status
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'ai/local-inference/status'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme ai/local-inference/status
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'ai/local-inference/status'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Ai Local Inference Status/test/unit/AiLocalInferenceStatusCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Ai Local Inference Status/test/integration/AiLocalInferenceStatusIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AiLocalInferenceStatusTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/AiLocalInferenceStatusBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AiLocalInferenceStatusServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/AiLocalInferenceStatusCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/AiLocalInferenceStatusIntegration.test.ts`

- * After generating response, AI validates if it actually answers the question.
- * Uses AIProviderDaemon for LLM-based evaluation.
+ * Thin TS shim — delegates to the Rust cognition/validate-response IPC.
+ * Rust owns the prompt, model call, and one-word decision parser
+ * (cognition/validate_response.rs). This command maps the public params
+ * shape into the IPC request and forwards the typed decision back.
+ *
+ * Replaces the previous parallel reimplementation (which carried its
+ * own prompt template + decision parser inline). Per Joel directive
+ * 2026-05-18 19:44Z: zero-users full-blown-Rust-dev mode — single PR
+ * adds the Rust path AND deletes the TS predecessor, no migration
+ * cadence.

+# Airc Bridge Command
+
+Ingest one AIRC message into Continuum. Normal messages become chat; explicit !continuum directives become bounded development and test commands. This is the inbox-side companion to airc/send: it lets AIRC peers drive Continuum validation without shelling through jtag chat/send or chat/export by hand.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag airc/bridge --message=<value>
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('airc/bridge', {
+  message: '!continuum ping',
+  senderNick: 'mac-codex',
+  channel: 'general',
+  dryRun: true
+});
+```
+
+## Parameters
+
+- **message** (required): `string` - Raw AIRC message body. Plain text is bridged into Continuum chat; messages beginning with the command prefix are parsed as bridge directives.
+- **senderNick** (optional): `string` - AIRC sender nick used for attribution in bridged chat text.
+- **channel** (optional): `string` - AIRC channel name, with or without leading #. Defaults to general.
+- **room** (optional): `string` - Continuum room name to target. Defaults to general; the AIRC channel is preserved separately for attribution and mirroring.
+- **commandPrefix** (optional): `string` - Directive prefix for test and control messages. Defaults to !continuum.
+- **dryRun** (optional): `boolean` - Parse and report intent without executing Continuum commands.
+- **mirrorResponse** (optional): `boolean` - Send bridge command responses back to AIRC via the airc CLI.
+
+## Result
+
+Returns `AircBridgeResult` with:
+
+Returns CommandResult with:
+- **handled**: `boolean` - True when the bridge executed the parsed action. Dry runs return handled=false.
+- **parsed**: `ParsedAircBridgeMessage` - Structured parser output for the incoming AIRC message.
+- **responseText**: `string` - Short human and AI readable response for the action.
+- **mirrored**: `boolean` - True when response mirroring to AIRC was requested and handed off successfully.
+- **mirrorError**: `string` - AIRC mirror failure, surfaced loudly instead of swallowed.
+- **commandResult**: `unknown` - Underlying Continuum command result for directives such as chat export or activity list.
+
+## Examples
+
+### Dry-run a normal chat message from AIRC
+
+```bash
+./jtag airc/bridge --message='hello from airc' --senderNick=mac-codex --channel=general --dryRun=true
+```
+
+### Check bridge health from AIRC
+
+```bash
+./jtag airc/bridge --message='!continuum ping' --senderNick=win-claude --channel=general --mirrorResponse=true
+```
+
+### Assert a marker landed in Continuum chat
+
+```bash
+./jtag airc/bridge --message='!continuum assert seen marker-123 --room general --last 100' --senderNick=mac-codex --channel=general
+```
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help airc/bridge
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'airc/bridge'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme airc/bridge
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'airc/bridge'
+```
+
+## Testing
+
+### Unit Tests
+
+Test parser behavior and the server command boundary:
+
+```bash
+# Run unit tests (no server required)
+npm --prefix commands/airc/bridge run test:unit
+```
+
+**What's tested:**
+- AIRC text/directive parsing
+- Room/channel normalization
+- Dry-run command execution
+- Missing-message rejection through the command boundary
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Live Validation
+
+Test the command against a matching running server with the branch deployed:
+
+```bash
+./jtag airc/bridge --message='!continuum ping' --senderNick=mac-codex --channel=general --dryRun=true
+./jtag airc/bridge --message='hello from airc' --senderNick=mac-codex --channel=general
+./jtag airc/bridge --message='!continuum assert seen marker-123 --room general --last 100'
+```
+
+**What's tested:**
+- `airc/bridge` is registered in the active server process
+- Chat messages route into Continuum chat
+- Export/assert directives can read back recent chat state
+- Optional AIRC mirroring fails loudly if the local bus is unavailable
+
+**Best Practice:**
+Run unit tests during development. Run live validation before PR review because `./jtag` talks to the currently running server, not necessarily the branch you just edited.
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AircBridgeTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/AircBridgeBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AircBridgeServerCommand.ts`
+- **Protocol Tests**: Parser coverage in `test/unit/AircBridgeProtocolCheck.ts`
+- **Server Tests**: Command boundary coverage in `test/unit/AircBridgeServerCommandCheck.ts`

+# Airc Send Command
+
+Send a message to the airc mesh from inside Continuum. Wraps the airc CLI's `airc send` command — broadcasts to a channel by default, DMs a peer when peer is provided. First-class surface for the AircBridge integration (continuum#967, AGENT-BACKBONE-INTEGRATION §11.2): personas (or any caller) can publish to the cross-machine peer mesh that humans + Claude Code + Codex tabs share. Outbox direction only; inbox routing (airc → persona inbox) is a separate v0.5 follow-up requiring an embedded `airc connect` Monitor process tree.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag airc/send --message=<value>
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('airc/send', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+- **message** (required): `string` - Message body to send. Plain text; airc handles encryption per its substrate rules.
+- **channel** (optional): `string` - Target channel (without leading #). Defaults to airc's auto-scoped project room (typically the cwd's git org → e.g. 'cambriantech'). Use 'general' for the lobby.
+- **peer** (optional): `string` - Target peer name for a DM (e.g. 'continuum-2c54'). When omitted, message is a broadcast to the channel. When provided, message is addressed to that peer specifically (still in the channel; airc envelopes the addressing).
+
+## Result
+
+Returns `AircSendResult` with:
+
+Returns CommandResult with:
+- **delivered**: `boolean` - True if airc CLI exited 0 and the message reached the local audit log. Note: airc's own substrate may queue (transient gist failure, secondary rate limit) — `delivered=true` means handed off to airc, not necessarily landed on a peer's bearer yet. Check airc#381 for the queue/retry semantics.
+- **channel**: `string` - Resolved channel name the message was sent to (after airc's auto-scoping).
+- **stderr**: `string` - Any stderr output from the airc CLI (warnings, [QUEUED] markers, [GONE] markers, etc.). Empty on clean delivery. Surfaced so callers can react to airc-substrate signals (rate-limit, channel-dissolved, etc.) rather than treating them as silent.
+
+## Examples
+
+### Broadcast to the auto-scoped project room
+
+```bash
+undefined
+```
+
+### Broadcast to #general explicitly
+
+```bash
+undefined
+```
+
+### DM a specific peer
+
+```bash
+undefined
+```
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help airc/send
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'airc/send'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme airc/send
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'airc/send'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Airc Send/test/unit/AircSendCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Airc Send/test/integration/AircSendIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/AircSendTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/AircSendBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/AircSendServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/AircSendCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/AircSendIntegration.test.ts`

+ * Airc Send Command - Server Implementation
+ *
+ * Wraps the airc CLI's `airc send` so any caller in Continuum (personas
+ * via their autonomous loop, dev tooling, future bridge module) can
+ * publish to the cross-machine peer mesh that humans + Claude Code +
+ * Codex tabs share. Outbox direction only — inbox routing (airc →
+ * persona inbox) is a separate v0.5 follow-up requiring an embedded
+ * `airc connect` Monitor process tree, tracked under continuum#967 +
+ * AGENT-BACKBONE-INTEGRATION §11.2.
+ *
+ * Channel resolution:
+ *   - explicit `params.channel`        → that channel
+ *   - omitted                          → airc's own auto-scope rule
+ *                                        (cwd's git-org → e.g. `cambriantech`)
+ *
+ * DM vs broadcast:
+ *   - `params.peer` provided           → addressed DM
+ *   - `params.peer` omitted            → broadcast to channel
+ *
+ * Failure surface:
+ *   - airc CLI not on PATH             → throws (mesh unreachable, fail loud)
+ *   - airc exits non-zero              → result.delivered=false + stderr surfaced
+ *   - airc exits zero with [QUEUED]    → result.delivered=true (queued counts;
+ *                                        airc's own drainer handles redelivery
+ *                                        per airc#381 layer B)
+ *   - airc exits zero with [GONE]      → result.delivered=true with stderr
+ *                                        carrying the [GONE] marker; caller
+ *                                        decides whether to re-host or wait

+# Cognition Admit Inbox Message Command
+
+Run the per-persona admission gate over a single InboxMessage. Returns the typed AdmissionDecision (Admit | Drop | Quarantine) plus the post-call admitted-engram count and trace seam count. Side effects: admitted engram → store, content_hash → dedup record, AIRC event_id → replay-protection record. Wraps the Rust IPC handler shipped in #1121 PR-4.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag cognition/admit-inbox-message --personaId=<value> --message=<value>
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('cognition/admit-inbox-message', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+- **personaId** (required): `string` - UUID of the persona whose admission gate runs
+- **message** (required): `Record<string, unknown>` - InboxMessageRequest — the candidate inbox message to admit. Recipe pipelines pass $signal or the drained-frame entry.
+
+## Result
+
+Returns `CognitionAdmitInboxMessageResult` with:
+
+Returns CommandResult with:
+- **decision**: `Record<string, unknown>` - Typed AdmissionDecision (Admit | Drop | Quarantine). See shared/generated/persona/AdmissionDecision.ts for shape.
+- **engramCount**: `number` - Total engrams in the persona's admitted store after this call
+- **traceSeamCount**: `number` - Number of cognition trace seams emitted during this admission
+
+## Examples
+
+### Admit an inbox message during a chat recipe pipeline
+
+```bash
+./jtag cognition/admit-inbox-message --personaId="<uuid>" --message='{"content":"hello","sender_id":"<uuid>"}'
+```
+
+**Expected result:**
+{ decision: { decision: 'Admit', data: {...} }, engramCount: 12, traceSeamCount: 3 }
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help cognition/admit-inbox-message
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'cognition/admit-inbox-message'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme cognition/admit-inbox-message
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'cognition/admit-inbox-message'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Cognition Admit Inbox Message/test/unit/CognitionAdmitInboxMessageCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Cognition Admit Inbox Message/test/integration/CognitionAdmitInboxMessageIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/CognitionAdmitInboxMessageTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/CognitionAdmitInboxMessageBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/CognitionAdmitInboxMessageServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/CognitionAdmitInboxMessageCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/CognitionAdmitInboxMessageIntegration.test.ts`

+# Cognition Recall Engrams Command
+
+Query a persona's admitted-engram store. Modes: 'recent' (default) returns newest-first N engrams; 'by_id' looks up by exact engram id; 'by_keyword' does case-insensitive substring match; 'by_origin' filters by EngramOriginKind (chat | airc | tool | self_reflection). Wraps the Rust IPC handler shipped in #1121 PR-5.

+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag cognition/recall-engrams --personaId=<value>
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('cognition/recall-engrams', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+- **personaId** (required): `string` - UUID of the persona whose engram store to query
+- **kind** (optional): `'recent' | 'by_id' | 'by_keyword' | 'by_origin'` - Recall mode (default: 'recent')
+- **limit** (optional): `number` - Max engrams to return (default: 10). Ignored when kind='by_id'.
+- **id** (optional): `string` - Engram UUID (required when kind='by_id')
+- **keyword** (optional): `string` - Substring to match against engram content (required when kind='by_keyword')
+- **origin** (optional): `'chat' | 'airc' | 'tool' | 'self_reflection'` - Origin filter (required when kind='by_origin')
+
+## Result
+
+Returns `CognitionRecallEngramsResult` with:
+
+Returns CommandResult with:
+- **engrams**: `Array<Record<string, unknown>>` - Matching engrams (typed as Engram in shared/generated/persona/Engram.ts)
+- **count**: `number` - Number of engrams returned
+
+## Examples
+
+### Recall the 5 most recent engrams during rag/build
+
+```bash
+./jtag cognition/recall-engrams --personaId="<uuid>" --kind="recent" --limit=5
+```
+
+**Expected result:**
+{ engrams: [...], count: 5 }

+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Cognition Recall Engrams/test/unit/CognitionRecallEngramsCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Cognition Recall Engrams/test/integration/CognitionRecallEngramsIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/CognitionRecallEngramsTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/CognitionRecallEngramsBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/CognitionRecallEngramsServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/CognitionRecallEngramsCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/CognitionRecallEngramsIntegration.test.ts`

+# Cognition Vision Describe Command
+
+Describe an image via the best available vision-capable model. Selects a vision-capable model from the Rust model registry, builds the describe prompt from option flags, dispatches `ai/generate` with multimodal content (text + base64 image), and parses the response into a VisionDescription. Migrated from `system/vision/VisionInferenceProvider.ts` per #1276 (oxidizer freeform-shape outlier — pairs with codex's #1284 structured-decision shape). Returns null when no vision model is registered or generation fails.

+
+## Usage
+
+### CLI Usage
+
+From the command line using the jtag CLI:
+
+```bash
+./jtag cognition/vision-describe --base64Data=<value> --mimeType=<value>
+```
+
+### Tool Usage
+
+From Persona tools or programmatic access using `Commands.execute()`:
+
+```typescript
+import { Commands } from '@system/core/shared/Commands';
+
+const result = await Commands.execute('cognition/vision-describe', {
+  // your parameters here
+});
+```
+
+## Parameters
+
+- **base64Data** (required): `string` - Base64-encoded image bytes. The Rust adapter shapes this for the destination provider (Anthropic native base64, OpenAI image_url, llama.cpp mmproj).
+- **mimeType** (required): `string` - Image MIME type (e.g. 'image/png', 'image/jpeg').
+- **options** (optional): `VisionDescribeOptions` - Per-call describe knobs (preferredModel, preferredProvider, maxLength, prompt override, detectObjects, detectColors, detectText). Defaults: concise prose with no structured-extraction prompts.
+
+## Result
+
+Returns `CognitionVisionDescribeResult` with:
+
+Returns CommandResult with:
+- **result**: `VisionDescription | null` - Description envelope or null when no vision model is registered / generation failed. See shared/generated/cognition/VisionDescription.ts.
+
+## Examples
+
+### Describe a PNG screenshot for the chat-side vision pipeline
+
+```bash
+./jtag cognition/vision-describe --base64Data="<base64>" --mimeType="image/png"
+```
+
+**Expected result:**
+{ description: 'A screenshot of...', modelId: '...', provider: '...', responseTimeMs: 1234 }
+
+## Getting Help
+
+### Using the Help Tool
+
+Get detailed usage information for this command:
+
+**CLI:**
+```bash
+./jtag help cognition/vision-describe
+```
+
+**Tool:**
+```typescript
+// Use your help tool with command name 'cognition/vision-describe'
+```
+
+### Using the README Tool
+
+Access this README programmatically:
+
+**CLI:**
+```bash
+./jtag readme cognition/vision-describe
+```
+
+**Tool:**
+```typescript
+// Use your readme tool with command name 'cognition/vision-describe'
+```
+
+## Testing
+
+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/Cognition Vision Describe/test/unit/CognitionVisionDescribeCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/Cognition Vision Describe/test/integration/CognitionVisionDescribeIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/CognitionVisionDescribeTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/CognitionVisionDescribeBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/CognitionVisionDescribeServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/CognitionVisionDescribeCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/CognitionVisionDescribeIntegration.test.ts`

- * Recipe Generate Command — LLM-powered recipe creation from natural language.

- * 2. Call LLM with the user's natural language description
- * 3. Parse and validate the generated JSON
- * 4. Save to system/recipes/<uniqueId>.json (unless dryRun)
+ * Pre-#1295 this file was 371 LOC owning prompt construction, AI dispatch,

+ * mission (#1248 umbrella) the prompt+parser+validator moved to Rust at
+ * `../core/continuum-core/src/cognition/generate_recipe/` and are exposed
+ * via the `cognition/generate-recipe` IPC (#1298 PR-1, #1301 PR-2).
+ *
+ * What this file owns now (TS-shim concerns only):
+ *   1. Validate the JTAG `description` parameter
+ *   2. Gather runtime registry state — `TemplateRegistry.list()` for the
+ *      available-templates carrier + `RecipeLoader.getInstance().getAllRecipes()`
+ *      for the existing-recipe-IDs carrier — and pass both into Rust
+ *   3. Call `Commands.execute('cognition/generate-recipe', ...)`
+ *   4. On the post-Rust success path: extra sentinel-template existence
+ *      check (TemplateRegistry.has — runtime-registry state Rust can't see),
+ *      saveRecipe to disk, RecipeLoader.clearCache + reload
+ *   5. Map the response into the existing `RecipeGenerateResult` JTAG envelope
+ *
+ * Outlier-validation pair with codex's #1284 (AIDecisionService) and

-## Available Sentinel Templates

-## Standard Pipeline Pattern
-
-Most recipes follow this pipeline:
-1. \`rag/build\` — Build context from conversation
-2. \`ai/should-respond\` — Decide if the AI should respond
-3. \`ai/generate\` — Generate the response
-
-## Rules
-
-1. Output ONLY the JSON object — no markdown fences, no explanation
-2. Every recipe MUST have a valid pipeline with at least the 3-step standard pattern
-3. The uniqueId must be kebab-case, descriptive, and unique
-4. responseRules should be specific and actionable — not vague platitudes
-5. decisionCriteria should be questions the AI asks itself
-6. feedbackLoopRules should be MANDATORY verification steps
-7. If the recipe involves sentinel workflows, reference only templates from the available list above
-8. roles.requires must use real capability names from the schema
-9. tags should be lowercase, relevant keywords
-10. version is always 1`;

-/**
- * Social Classify Command - Shared Types
- *
- * Multi-dimensional agent classification system.
- * Analyzes an external agent's profile, posting history, and engagement
- * to produce a probability vector characterizing who they are.
- *
- * Like an embedding space for AI personas on external social media.
- * Uses existing subcommands (browse, search) to gather data,
- * then produces scores across multiple dimensions.
- *
- * Dimensions:
- *   spam        — Probability of being a spambot (repetitive, low-quality, template content)
- *   authentic   — Original content vs copypasta/shill
- *   expertise   — Domain knowledge signals (security, coding, philosophy, etc.)
- *   influence   — Community impact (karma, engagement, followers)
- *   engagement  — Quality of conversations (threaded depth, substantive replies)
- *   reliability — Consistency over time (not one-hit wonder)
- *
- * Usage:
- *   ./jtag social/classify --platform=moltbook --target=eudaemon_0
- *   ./jtag social/classify --platform=moltbook --target=snorf5163
- *   ./jtag social/classify --platform=moltbook --target=Cody --depth=deep

-
-## Examples
-
-### Comment on a post
-
-```bash
-./jtag social/comment --platform=moltbook --postId=abc123 --content="Great insight!"
-```
-
-**Expected result:**
-{ success: true, comment: { id: '...' } }
-
-### Reply to a comment (threaded)
-
-```bash
-./jtag social/comment --platform=moltbook --postId=abc123 --content="Agreed" --parentId=def456
-```
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/comment
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/comment'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/comment
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/comment'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/comment/test/unit/SocialCommentCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/comment/test/integration/SocialCommentIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialCommentTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialCommentBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialCommentServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialCommentCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialCommentIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/community --platform=<value> --action=<value> --name=<value> --description=<value> --personaId=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/community', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform (e.g., 'moltbook')
-- **action** (required): `string` - Action: list, info, create, subscribe, unsubscribe
-- **name** (required): `string` - Community name (required for info, create, subscribe, unsubscribe)
-- **description** (required): `string` - Community description (for create)
-- **personaId** (required): `string` - Persona user ID (auto-detected)
-
-## Result
-
-Returns `SocialCommunityResult` with:
-
-Returns CommandResult with:
-- **success**: `boolean` - Whether the action succeeded
-- **communities**: `object[]` - List of communities (for list action)
-- **community**: `object` - Community info (for info/create actions)
-
-## Examples
-
-### List all communities
-
-```bash
-./jtag social/community --platform=moltbook --action=list
-```
-
-**Expected result:**
-{ success: true, communities: [...] }
-
-### Create a community
-
-```bash
-./jtag social/community --platform=moltbook --action=create --name=continuum-devs --description='Continuum builders'
-```
-
-**Expected result:**
-{ success: true, community: { name: 'continuum-devs' } }
-
-### Subscribe to a community
-
-```bash
-./jtag social/community --platform=moltbook --action=subscribe --name=ai-development
-```
-
-**Expected result:**
-{ success: true }
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/community
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/community'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/community
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/community'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/community/test/unit/SocialCommunityCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/community/test/integration/SocialCommunityIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialCommunityTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialCommunityBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialCommunityServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialCommunityCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialCommunityIntegration.test.ts`

-- [Access Level](#access-level)
-- [Implementation Notes](#implementation-notes)
-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/downvote --platform=<value> --postId=<value> --personaId=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/downvote', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform (e.g., 'moltbook')
-- **postId** (required): `string` - Post ID to downvote
-- **personaId** (required): `string` - Persona user ID (auto-detected)
-
-## Result
-
-Returns `SocialDownvoteResult` with:
-
-Returns CommandResult with:
-- **success**: `boolean` - Whether the downvote was successful
-- **postId**: `string` - The post that was downvoted
-
-## Examples
-
-### Downvote a spam post
-
-```bash
-./jtag social/downvote --platform=moltbook --postId=abc123
-```
-
-**Expected result:**
-{ success: true, postId: 'abc123' }
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/downvote
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/downvote'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/downvote
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/downvote'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/downvote/test/unit/SocialDownvoteCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/downvote/test/integration/SocialDownvoteIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialDownvoteTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialDownvoteBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialDownvoteServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialDownvoteCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialDownvoteIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/feed --platform=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/feed', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to read from (e.g., 'moltbook')
-- **sort** (optional): `string` - Sort order: hot, new, top, rising
-- **community** (optional): `string` - Community/submolt to filter by
-- **limit** (optional): `number` - Maximum number of posts to return
-- **personalized** (optional): `boolean` - Whether to show personalized feed
-- **personaId** (optional): `UUID` - Persona user ID (auto-detected if not provided)
-
-## Result
-
-Returns `SocialFeedResult` with:
-
-Returns CommandResult with:
-- **message**: `string` - Human-readable result message
-- **posts**: `SocialPostData[]` - Array of feed posts
-
-## Examples
-
-### Read the hot feed from Moltbook
-
-```bash
-./jtag social/feed --platform=moltbook --sort=hot --limit=10
-```
-
-**Expected result:**
-{ success: true, posts: [...] }
-
-### Read a community feed
-
-```bash
-./jtag social/feed --platform=moltbook --community=ai-development --sort=new
-```
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/feed
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/feed'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/feed
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/feed'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/feed/test/unit/SocialFeedCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/feed/test/integration/SocialFeedIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialFeedTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialFeedBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialFeedServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialFeedCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialFeedIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/notifications --platform=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/notifications', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to check (e.g., 'moltbook')
-- **since** (optional): `string` - ISO timestamp to fetch notifications since
-- **limit** (optional): `number` - Maximum number of notifications to return
-- **personaId** (optional): `UUID` - Persona user ID (auto-detected if not provided)
-
-## Result
-
-Returns `SocialNotificationsResult` with:
-
-Returns CommandResult with:
-- **message**: `string` - Human-readable result message
-- **notifications**: `SocialNotification[]` - Array of notifications
-- **unreadCount**: `number` - Count of unread notifications
-
-## Examples
-
-### Check recent notifications
-
-```bash
-./jtag social/notifications --platform=moltbook
-```
-
-**Expected result:**
-{ success: true, notifications: [...], unreadCount: 3 }
-
-### Check notifications since a specific time
-
-```bash
-./jtag social/notifications --platform=moltbook --since=2026-01-30T00:00:00Z
-```
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/notifications
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/notifications'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/notifications
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/notifications'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/notifications/test/unit/SocialNotificationsCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/notifications/test/integration/SocialNotificationsIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialNotificationsTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialNotificationsBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialNotificationsServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialNotificationsCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialNotificationsIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/post --platform=<value> --title=<value> --content=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/post', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to post on (e.g., 'moltbook')
-- **title** (required): `string` - Post title
-- **content** (required): `string` - Post content/body
-- **community** (optional): `string` - Community/submolt to post in
-- **url** (optional): `string` - URL for link posts
-- **personaId** (optional): `UUID` - Persona user ID (auto-detected if not provided)
-
-## Result
-
-Returns `SocialPostResult` with:
-
-Returns CommandResult with:
-- **message**: `string` - Human-readable result message
-- **post**: `SocialPostData` - Created post details
-
-## Examples
-
-### Create a post on Moltbook
-
-```bash
-./jtag social/post --platform=moltbook --title="Hello" --content="First post" --community=general
-```
-
-**Expected result:**
-{ success: true, post: { id: '...', title: 'Hello' } }
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/post
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/post'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/post
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/post'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/post/test/unit/SocialPostCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/post/test/integration/SocialPostIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialPostTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialPostBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialPostServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialPostCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialPostIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/profile --platform=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/profile', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to query (e.g., 'moltbook')
-- **agentName** (optional): `string` - Agent name to look up (omit for own profile)
-- **update** (optional): `boolean` - If true, update own profile instead of viewing
-- **description** (optional): `string` - New profile description/bio (requires --update)
-- **personaId** (optional): `string` - Persona user ID (auto-detected if not provided)
-
-## Result
-
-Returns `SocialProfileResult` with:
-
-Returns CommandResult with:
-- **profile**: `SocialProfile` - The profile data (when viewing)
-- **updated**: `boolean` - Whether profile was updated (when updating)
-
-## Examples
-
-### View your own profile
-
-```bash
-./jtag social/profile --platform=moltbook
-```
-
-**Expected result:**
-{ success: true, profile: { agentName: 'helper-ai', karma: 42, ... } }
-
-### View another agent's profile
-
-```bash
-./jtag social/profile --platform=moltbook --agentName=other-agent
-```
-
-### Update your bio
-
-```bash
-./jtag social/profile --platform=moltbook --update --description="I help with code"
-```
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/profile
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/profile'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/profile
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/profile'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/profile/test/unit/SocialProfileCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/profile/test/integration/SocialProfileIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialProfileTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialProfileBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialProfileServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialProfileCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialProfileIntegration.test.ts`

- *
- * Democratic governance for shared social media accounts.
- * Personas nominate actions, vote, and auto-execute on threshold.

- * Proposals are stored as Handles (type 'social-proposal') with votes in params.
- * When enough "up" votes accumulate, the action executes automatically.
- *
- * Modes:
- *   create  — Nominate a new action (follow, post, comment, etc.)
- *   vote    — Vote on a pending proposal
- *   list    — Show pending/recent proposals
- *   view    — View a specific proposal with full vote history
- *
- * Usage:
- *   ./jtag social/propose --platform=moltbook --mode=create --action=follow --target=eudaemon_0 --reason="Great security research"
- *   ./jtag social/propose --mode=vote --proposalId=abc123 --direction=up

-
-```bash
-./jtag social/signup --platform=<value> --agentName=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/signup', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to register on (e.g., 'moltbook')
-- **agentName** (required): `string` - Desired username on the platform
-- **description** (optional): `string` - Profile description/bio
-- **personaId** (optional): `UUID` - Persona user ID (auto-detected if not provided)
-- **metadata** (optional): `Record<string, unknown>` - Additional platform-specific metadata
-
-## Result
-
-Returns `SocialSignupResult` with:
-
-Returns CommandResult with:
-- **message**: `string` - Human-readable result message
-- **apiKey**: `string` - API key for future authenticated requests
-- **agentName**: `string` - Assigned username on the platform
-- **claimUrl**: `string` - URL to claim/verify the account
-- **profileUrl**: `string` - URL to the agent's profile page
-- **verificationCode**: `string` - Verification code if applicable
-
-## Examples
-
-### Register a persona on Moltbook
-
-```bash
-./jtag social/signup --platform=moltbook --agentName="helper-ai" --description="I help with code"
-```
-
-**Expected result:**
-{ success: true, agentName: 'helper-ai', profileUrl: '...' }
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/signup
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/signup'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/signup
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/signup'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/signup/test/unit/SocialSignupCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/signup/test/integration/SocialSignupIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialSignupTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialSignupBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialSignupServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialSignupCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialSignupIntegration.test.ts`

-
-## Usage
-
-### CLI Usage
-
-From the command line using the jtag CLI:
-
-```bash
-./jtag social/trending --platform=<value>
-```
-
-### Tool Usage
-
-From Persona tools or programmatic access using `Commands.execute()`:
-
-```typescript
-import { Commands } from '@system/core/shared/Commands';
-
-const result = await Commands.execute('social/trending', {
-  // your parameters here
-});
-```
-
-## Parameters
-
-- **platform** (required): `string` - Platform to browse (e.g., 'moltbook')
-- **sort** (optional): `string` - Sort order: hot (default), top, rising
-- **community** (optional): `string` - Filter to specific community/submolt
-- **limit** (optional): `number` - Maximum number of posts to return (default: 10)
-- **personaId** (optional): `string` - Persona user ID (auto-detected if not provided)
-
-## Result
-
-Returns `SocialTrendingResult` with:
-
-Returns CommandResult with:
-- **posts**: `SocialPost[]` - Array of trending posts
-- **community**: `string` - Community filter applied (if any)
-
-## Examples
-
-### See what's hot across the platform
-
-```bash
-./jtag social/trending --platform=moltbook
-```
-
-**Expected result:**
-{ success: true, posts: [...], message: 'Fetched 10 trending posts...' }
-
-### Top posts in a specific community
-
-```bash
-./jtag social/trending --platform=moltbook --community=ai-development --sort=top
-```
-
-### Rising discussions with limit
-
-```bash
-./jtag social/trending --platform=moltbook --sort=rising --limit=5
-```
-
-## Getting Help
-
-### Using the Help Tool
-
-Get detailed usage information for this command:
-
-**CLI:**
-```bash
-./jtag help social/trending
-```
-
-**Tool:**
-```typescript
-// Use your help tool with command name 'social/trending'
-```
-
-### Using the README Tool
-
-Access this README programmatically:
-
-**CLI:**
-```bash
-./jtag readme social/trending
-```
-
-**Tool:**
-```typescript
-// Use your readme tool with command name 'social/trending'
-```
-
-## Testing
-
-### Unit Tests
-
-Test command logic in isolation using mock dependencies:
-
-```bash
-# Run unit tests (no server required)
-npx tsx commands/social/trending/test/unit/SocialTrendingCommand.test.ts
-```
-
-**What's tested:**
-- Command structure and parameter validation
-- Mock command execution patterns
-- Required parameter validation (throws ValidationError)
-- Optional parameter handling (sensible defaults)
-- Performance requirements
-- Assertion utility helpers
-
-**TDD Workflow:**
-1. Write/modify unit test first (test-driven development)
-2. Run test, see it fail
-3. Implement feature
-4. Run test, see it pass
-5. Refactor if needed
-
-### Integration Tests
-
-Test command with real client connections and system integration:
-
-```bash
-# Prerequisites: Server must be running
-npm start  # Wait 90+ seconds for deployment
-
-# Run integration tests
-npx tsx commands/social/trending/test/integration/SocialTrendingIntegration.test.ts
-```
-
-**What's tested:**
-- Client connection to live system
-- Real command execution via WebSocket
-- ValidationError handling for missing params
-- Optional parameter defaults
-- Performance under load
-- Various parameter combinations
-
-**Best Practice:**
-Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
-
-## Access Level
-
-**ai-safe** - Safe for AI personas to call autonomously
-
-## Implementation Notes
-
-- **Shared Logic**: Core business logic in `shared/SocialTrendingTypes.ts`
-- **Browser**: Browser-specific implementation in `browser/SocialTrendingBrowserCommand.ts`
-- **Server**: Server-specific implementation in `server/SocialTrendingServerCommand.ts`
-- **Unit Tests**: Isolated testing in `test/unit/SocialTrendingCommand.test.ts`
-- **Integration Tests**: System testing in `test/integration/SocialTrendingIntegration.test.ts`

+# System Docker Tier Stats Command
+
+Snapshot of the Docker storage tier (capacity, used bytes, pressure ratio, detection state). Phase 1 of #1239 — exposes the data the existing `DockerTierPool` (`modules/docker_tier_pool.rs`) already computes, without depending on the not-yet-instantiated `PressureBroker` singleton. Wired so `bin/continuum status` can surface a `Docker disk: ...` row + warn at >90%, and so future scheduler hot paths can refuse before ENOSPC. Returns `detected: false` + zeros on hosts where Docker isn't installed.

+### Unit Tests
+
+Test command logic in isolation using mock dependencies:
+
+```bash
+# Run unit tests (no server required)
+npx tsx commands/System Docker Tier Stats/test/unit/SystemDockerTierStatsCommand.test.ts
+```
+
+**What's tested:**
+- Command structure and parameter validation
+- Mock command execution patterns
+- Required parameter validation (throws ValidationError)
+- Optional parameter handling (sensible defaults)
+- Performance requirements
+- Assertion utility helpers
+
+**TDD Workflow:**
+1. Write/modify unit test first (test-driven development)
+2. Run test, see it fail
+3. Implement feature
+4. Run test, see it pass
+5. Refactor if needed
+
+### Integration Tests
+
+Test command with real client connections and system integration:
+
+```bash
+# Prerequisites: Server must be running
+npm start  # Wait 90+ seconds for deployment
+
+# Run integration tests
+npx tsx commands/System Docker Tier Stats/test/integration/SystemDockerTierStatsIntegration.test.ts
+```
+
+**What's tested:**
+- Client connection to live system
+- Real command execution via WebSocket
+- ValidationError handling for missing params
+- Optional parameter defaults
+- Performance under load
+- Various parameter combinations
+
+**Best Practice:**
+Run unit tests frequently during development (fast feedback). Run integration tests before committing (verify system integration).
+
+## Access Level
+
+**ai-safe** - Safe for AI personas to call autonomously
+
+## Implementation Notes
+
+- **Shared Logic**: Core business logic in `shared/SystemDockerTierStatsTypes.ts`
+- **Browser**: Browser-specific implementation in `browser/SystemDockerTierStatsBrowserCommand.ts`
+- **Server**: Server-specific implementation in `server/SystemDockerTierStatsServerCommand.ts`
+- **Unit Tests**: Isolated testing in `test/unit/SystemDockerTierStatsCommand.test.ts`
+- **Integration Tests**: System testing in `test/integration/SystemDockerTierStatsIntegration.test.ts`

+/**
+ * RustBackedCommand — base class for the standard "validate → call mixin →
+ * wrap result" envelope shared by every TS command that exists ONLY to
+ * route into a Rust IPC handler (#1198).
+ *
+ * # Why this exists
+ *
+ * Per Joel's "TS moves DOWN into rust… if not UI/UX it is rust" rule
+ * (2026-05-14), every Rust-backed TS command in `src/commands/*` does
+ * the same five things in the same order:
+ *
+ *   1. Validate the required params (throw `ValidationError` with a
+ *      consistent message + missing-field name)
+ *   2. Resolve the Rust IPC client singleton
+ *   3. Call the typed mixin method on the client
+ *   4. Translate the snake_case Rust response into the camelCase
+ *      `Result` shape via `createXResultFromParams`
+ *   5. Return the wrapped result
+ *
+ * Steps 1, 2, and 5 are pure boilerplate. Steps 3 and 4 are the only
+ * variable bits per command. The pre-#1198 status quo was every command
+ * re-writing the boilerplate inline, ~30 LOC of envelope around ~5 LOC
+ * of actual call. That's uncompressed redundancy → drift target (the
+ * specific drift the compression principle in CLAUDE.md exists to
+ * prevent).
+ *
+ * # How to use
+ *
+ * Subclass declares: `requiredParams` (which fields must be non-empty),
+ * `callRust(params, client)` (the variable mixin call), and
+ * `toResult(raw, params)` (the variable result wrapping). Base class
+ * owns: validation loop, client resolution, error consistency.
+ *
+ * See `commands/cognition/admit-inbox-message/server/CognitionAdmitInboxMessageServerCommand.ts`
+ * for the canonical example refactored under #1198.
+ *
+ * # Why TRest is generic (not `unknown`)
+ *
+ * Each subclass knows the exact mixin response shape (it's a typed
+ * ts-rs export). Threading it through `TRest` lets `toResult` be
+ * type-safe instead of carrying an `unknown` cast. Subclasses that
+ * don't care can use `unknown` explicitly.
+ *
+ * # Custom validation
+ *
+ * Subclasses that need richer per-field validation than non-empty
+ * (e.g., shape constraints like `typeof params.message === 'object'`)
+ * override `validateParams(params)` and call `super.validateParams(params)`
+ * BEFORE adding their custom checks. This preserves the consistent
+ * required-field behavior.

+# Alpha Gap: Rust Persona Runtime
+
+## Status
+
+Continuum is not alpha-ready while persona chat depends on TypeScript as the runtime authority.
+
+The current failure is measurable:
+
+- PR #1061 live smoke on Mac M-series, branch `fix/persona-chat-inference-priority`, marker `codex-1061-chat-smoke-1778202469`.
+- `collaboration/chat/send` stored the message immediately.
+- After 195 seconds, only CodeReview AI replied.
+- Teacher, Helper, Local Assistant, and Vision AI did not reply.
+
+That means the issue is larger than background Hippocampus LLM contention. Node-side orchestration is too slow, too opaque, and too easy to regress. The persona system needs the same shape as a high-performance 3D engine: a Rust frame/turn loop, explicit resource budgets, predictable scheduling, and thin adapters at the edge.
+
+## Product Bar
+
+Alpha chat must meet these gates on a local machine:
+
+- First visible local persona response in under 10 seconds for text-only chat.
+- All eligible local personas either respond or emit observable silence reasons within 30 seconds.
+- No background memory, RAG, embedding, or health job may consume the visible chat inference lane without Rust scheduler admission.
+- Model/provider choice must come from a single typed registry and capability query, not string checks scattered through TS.
+- Local means Qwen/llama.cpp through Continuum's runtime. Ollama is not a supported concept.
+- UI and commands may be TypeScript, but persona runtime authority must be Rust.
+
+## Engine Model
+
+Rust owns:
+
+- Turn admission and batching.
+- Persona response scheduling.
+- Dependency wakeups between turn artifacts and subscriber work.
+- Local inference lane capacity.
+- Model and provider selection.
+- RAG source fan-out and shared cache keys.
+- Memory consolidation admission.
+- LoRA, KV, and multimodal resource paging.
+- Runtime metrics and slow-command evidence.
+
+TypeScript owns:
+
+- Browser UI.
+- Command adapters.
+- Entity loading until the data module is fully Rust-backed.
+- Presentation and operator tooling.
+
+TypeScript must not own:
+
+- Which personas run.
+- In what order they run.
+- How many local generations run at once.
+- Which model satisfies a capability request.
+- Whether background work may use the inference lane.
+
+## CBAR Precedent: Turn Frames, Not FIFO Chat
+
+The old CB mobile SDK solved the same class of problem under harder latency
+pressure. Its C++ core owned the frame loop, cache invalidation, analyzer
+cadence, and backpressure; Objective-C, Swift, Kotlin, and web wrappers were
+bindings. Continuum needs the same split: Rust is the engine, TypeScript is a
+thin adapter.
+
+The direct mapping:
+
+- `CBAR_VideoFrame` becomes a `CognitionTurnFrame`.
+- Lazy image getters become lazy turn artifacts: canonical room snapshot,
+  conversation history, shared RAG results, capability plan, model selection,
+  prompt fragments, embedding batches, and memory deltas.
+- Analyzer subscribers become persona recipes, memory jobs, RAG jobs, tool
+  jobs, and airc bridge jobs.
+- `QueueThread<T>` priority/cadence becomes Rust resource-class queues with
+  explicit local inference, embedding, I/O, and background budgets.
+- Frame-drop backpressure becomes stale-work cancellation: if a newer chat
+  turn supersedes a background semantic-memory synthesis job, keep the latest
+  raw memory and drop or defer the stale synthesis.
+
+The core rule is dependency wakeup, not global FIFO. Work never waits for
+unrelated work. A job declares which artifact keys it needs; when those keys
+become ready, subscribers wake. If terrain changes in CBAR, semantic
+segmentation, color filtering, ORB, SLAM, and surface accumulation wake
+according to their declared cadence. If a chat turn arrives in Continuum, the
+shared turn artifacts build once, then eligible personas, memory jobs, and
+export/airc observers wake from those artifacts.
+
+The architecture must preserve these invariants:
+
+- The hot path never blocks on background work.
+- Runtime workers should stay busy with ready work, but worker saturation must
+  not become a global lock.
+- The scheduler starts from maximum safe parallelism: CPUs busy, GPU admitted
+  deliberately, and independent work running concurrently. It reduces cadence,
+  precision, or concurrency only when measured pressure or dependency order
+  requires it.
+- Shared artifacts are computed once per turn and cached by stable key.
+- Subscribers can run at different cadences and priorities.
+- Each subscriber owns its trigger predicate: artifact changed, elapsed time,
+  resource pressure changed, explicit command, or human/agent event.
+- Backpressure prefers latest useful state over draining stale queues.
+- Model/GPU work is admitted by Rust before it starts.
+- Wrapper layers do not invent scheduling policy.
+
+## Contract Style: Small Interfaces, Opaque Engines
+
+CBAR kept the hard machinery behind small C++ classes. `PIMPL` hid memory
+layout, cache state, thread ownership, and platform-specific buffers while the
+public headers stayed small. Continuum needs the Rust equivalent:
+
+- Public contracts are small typed structs and traits.
+- Runtime state is opaque and owned by Rust.
+- Boundaries pass handles, ids, and leases instead of copying memory. Large
+  payloads such as media frames, embeddings, KV caches, model weights, LoRA
+  pages, WebRTC buffers, and Bevy textures stay resident in their owning pool.
+- Extension points are capability/recipe/model traits, not callback trees full
+  of scheduling policy.
+- Threading and multiprocessing are low-friction because queues, wakeups,
+  pressure, and metrics are inherited from the engine.
+- Adding a new persona recipe, model family, LoRA paging policy, RAG source, or
+  game observer should mean implementing a narrow trait and declaring
+  dependencies, not rewriting orchestration.
+
+The repeated pattern should be:
+
+1. Declare input artifacts and capabilities.
+2. Declare resource class and budget.
+3. Pass artifact handles, not copied payloads.
+4. Implement the small work trait.
+5. Let Rust schedule, coalesce, wake, defer, and measure it.
+
+That is the SOLID boundary for this project. Wrappers and feature modules ask
+for work; the Rust engine decides how to run it.
+
+This also covers always-on contexts such as a game running in the background.
+The game stream is just another artifact producer. New terrain, changed quest
+state, visible enemies, or elapsed cadence can wake vision, code, memory, or
+planning subscribers without blocking chat. If the GPU budget is tight, Rust
+degrades intentionally: skip stale frames, lower cadence, summarize, or emit a
+silence/deferred reason. It must not let background perception kill visible
+conversation.
+
+This is the engine-level answer to the current persona flood. The failure is
+not just "too many messages"; it is missing turn-frame consolidation. Multiple
+personas responding to one room event should share one room snapshot, one RAG
+fan-out, one model-capability resolution, and one scheduler decision. They
+should not each build a private universe and fight over the same local model.
+
+## Existing Rust Assets
+
+Keep and extend these instead of recreating logic in TypeScript:
+
+- `workers/continuum-core/src/cognition/turn_batch.rs`: deterministic per-turn planning.
+- `workers/continuum-core/src/persona/channel_queue.rs`: consolidated domain queues.
+- `workers/continuum-core/src/persona/channel_registry.rs`: service-cycle scheduling.
+- `workers/continuum-core/src/persona/response.rs`: per-persona response path.
+- `workers/continuum-core/src/persona/model_selection.rs`: adapter-aware model selection.
+- `workers/continuum-core/src/model_registry/*`: typed model/provider/capability registry.
+- `workers/continuum-core/src/inference/backends/llamacpp_scheduler.rs`: llama.cpp scheduling.
+- `workers/continuum-core/src/paging/broker.rs`: cross-pool pressure broker.
+- `workers/continuum-core/src/runtime/*`: module registry, metrics, IPC, event bus, and concurrency limits.
+
+## Adaptive Throughput Substrate
+
+The best complete throughput design in the Cambrian codebase is CBAR:
+bounded `QueueThread` workers, lazy frame artifacts, subscriber analyzers,
+priority/cadence, newest-state backpressure, and thin platform wrappers.
+Continuum has several strong Rust primitives, but they are not yet one unified
+substrate:
+
+- `ServiceModule` and `ModuleConfig`: one runtime extension seam for commands,
+  event subscriptions, priority, concurrency, and ticks.
+- `MessageBus`: typed event fan-out with coalescing and recent-event replay.
+- `llamacpp_scheduler`: continuous local generation, sequence attribution, and
+  future LoRA/KV routing point.
+- `FootprintRegistry`: cross-resource accounting by backend, persona, and
+  resource kind.
+- `PagedResourcePool`: generic residency, pinning, LRU-style eviction, stats,
+  and reload/spill hooks.
+- `PressureBroker`: cross-pool pressure decisions.
+- `ChannelQueue` / `QueueItemBehavior`: generic containers where domain items
+  own priority, consolidation, and staleness.
+
+These should converge into one reusable adaptive-throughput pattern for every
+expensive process:
+
+1. A job declares identity: `turn_key`, `artifact_key`, `persona_id`,
+   `resource_class`, and optional `recipe/model/provider`.
+2. A job declares dependencies by handle, not payload.
+3. A scheduler admits the job when dependencies are ready and resources fit.
+4. The job runs in the narrowest resource lane that can satisfy it: CPU, data,
+   GPU, embedding, local generation, cloud provider, I/O, media, render,
+   memory, or background.
+5. The job emits typed artifacts/events and updates footprint/trace metrics.
+6. Downstream subscribers wake from artifact readiness, not from global FIFO.
+
+This becomes the repeated process model for chat, RAG, memory consolidation,
+embedding, vision, live video, game observers, LoRA paging, MoE expert routing,
+airc bridging, and grid-distributed work.
+
+The same substrate must cover the historically troublesome paths:
+
+- ORM/data: canonical entity resolution and query work move through `Data`
+  lanes and emit handles, not browser-authoritative identity blobs.
+- Inference: local Qwen/llama.cpp generation moves through `LocalGeneration`
+  lanes backed by model residency and KV/LoRA pressure.
+- WebRTC/audio/video: packet/frame work moves through `Media` lanes and passes
+  frame ids, buffer leases, and content hashes.
+- Bevy/live rendering: render work moves through `Render` lanes and passes
+  texture ids or GPU residency handles.
+
+The substrate must be adaptive before it is clever:
+
+- Start from maximum safe parallelism.
+- Keep CPU workers busy with independent ready work.
+- Admit GPU/model work deliberately from memory and lane evidence.
+- Prefer latest useful state over draining stale queues.
+- Coalesce repeated work by stable identity keys.
+- Degrade cadence, precision, context, or subscriber count under pressure.
+- Surface deferrals and silence reasons as first-class output.
+- Never copy large payloads across process or language boundaries when a handle
+  can identify resident data.
+
+The failure to avoid is every module owning its own queue, throttle, retry,
+cache, and memory heuristic. The extension author should implement a small
+contract and inherit the hard parts: scheduling, pressure, telemetry, artifact
+cache negotiation, and wakeups.
+
+### Pipes Carry Leases, Not Bytes
+
+Continuum already moves audio, video, WebRTC/UDP traffic, Docker-hosted
+services, inference contexts, embeddings, and chat artifacts across module
+boundaries. Generic IPC becomes the bottleneck when each boundary copies the
+bytes and each module rehydrates its own view of the world.
+
+The shared pattern must be:
+
+- Media frames live in a media/frame pool and cross boundaries as frame ids,
+  texture ids, or buffer leases.
+- WebRTC/UDP payloads stay in transport-owned buffers until a subscriber
+  explicitly needs a decoded artifact.
+- Embeddings live in an embedding pool and cross boundaries as vector handles
+  plus version/content hashes.
+- KV cache pages, LoRA pages, mmproj weights, and model weights live in paging
+  pools and cross boundaries as residency leases.
+- Chat/RAG/context artifacts live behind stable turn keys and source hashes,
+  not copied prompt blobs on every persona call.
+- Docker/process boundaries use the same handle protocol when the underlying
+  memory cannot be shared directly: pass ids, ranges, hashes, offsets, and
+  leases; copy only at the final unavoidable edge.
+
+IPC should move control messages and handles. Bulk bytes stay resident in the
+nearest owning pool. This is how the system avoids clogging pipes while still
+letting independent modules subscribe to the same live world.
+
+## Failure Modes To Eliminate
+
+### Single-Responder Collapse
+
+Symptom: only one persona replies to a broad human message.
+
+Root causes to prevent:
+
+- TS-side coordination window or locks silently deciding for all personas.
+- Local provider queue monopolized by one persona or background work.
+- RAG/source fan-out repeated per persona until the first responder consumes all budget.
+
+Rust fix:
+
+- `cognition/plan-turn-batch` returns one `PersonaTurnPlan` per candidate, with generation order, wave, estimated start, and estimated finish.
+- The host must execute that plan or surface why it cannot.
+- A later Rust `persona/run-turn` command should execute the plan directly and return posted response envelopes.
+- The plan is the first `CognitionTurnFrame`: every shared artifact in it must
+  be reused across persona subscribers unless explicitly declared
+  persona-local.
+- The plan exposes whether the turn can meet the first-response and
+  all-responses alpha budgets before expensive execution starts.
+
+### Slow Chat
+
+Symptom: first reply arrives after 95+ seconds.
+
+Root causes to prevent:
+
+- Node event loop is the scheduler.
+- Background tasks share local generation without admission.
+- Model startup, RAG, and memory work are serialized without a visible plan.
+
+Rust fix:
+
+- Planner consumes local capacity from `inference/capacity`.
+- Planner emits waves and expected timing.
+- Runtime metrics report queue time versus execution time for every module command.
+
+### ORM And Room Identity Drift
+
+Symptom: stale General room tabs, wrong UUIDs, old chat rows, localStorage resurrecting ghost rooms.
+
+Root causes to prevent:
+
+- Multiple sources of truth for default rooms.
+- URL rewrite before canonical room resolution.
+- Browser-local state overriding ORM truth.
+
+Rust fix:
+
+- Data module becomes the canonical room/activity resolver.
+- UI receives canonical handles after resolution.
+- Browser caches may remember view state, not entity identity.
+
+### IPC Drift
+
+Symptom: TS and Rust believe different things about capacity, model capabilities, or command state.
+
+Root causes to prevent:
+
+- Hand-written TS types or duplicate constants.
+- Commands returning success while the downstream runtime did nothing.
+- Fire-and-forget process boundaries hiding failures.
+
+Rust fix:
+
+- ts-rs generated contracts for planner/runtime payloads.
+- Command execution throws on failure at the caller boundary.
+- Runtime metrics expose command queue time and error count.
+
+## PR Sequence
+
+### PR A: Rust Turn Schedule Contract
+
+Purpose: make scheduling explicit and testable.
+
+Scope:
+
+- Extend `RecipeTurnBatchRequest` with `local_inference_capacity`.
+- Extend `PersonaTurnPlan` with `generation_wave`, `estimated_start_ms`, and `estimated_finish_ms`.
+- Extend `RecipeTurnBatchPlan` with first-response/all-responses budget
+  evidence.
+- Keep planner pure: no ORM, no inference, no filesystem.
+- Add unit tests for deterministic waves and capacity.
+- Document the CBAR-derived dependency-wakeup model as the alpha runtime
+  direction.
+
+Validation:
+
+- `cargo test -p continuum-core --features metal,accelerate cognition::turn_batch --lib`
+
+### PR B: TypeScript Adapter Obeys Rust Plan
+
+Purpose: stop TS from inventing its own fan-out and ordering.
+
+Scope:
+
+- The chat path calls `cognition/plan-turn-batch` before building per-persona context.
+- RAG shared sources are loaded once per turn.
+- Persona execution follows `generation_wave` and local capacity.
+- If execution diverges from plan, log a structured runtime error.
+
+Validation:
+
+- Browser chat smoke sends one marker.
+- Export must show every eligible persona either responded or emitted a silence reason within 30 seconds.
+- Runtime metrics must show no unplanned local inference calls.
+
+### PR C: Rust Persona Run-Turn
+
+Purpose: move the turn loop into Rust.
+
+Scope:
+
+- Add `cognition/run-turn` or `persona/run-turn`.
+- Input: trigger, candidates, room snapshot, model/capability declarations.
+- Output: response envelopes and silence reasons.
+- Rust uses the channel registry and response path directly.
+- TypeScript only posts returned envelopes through existing chat storage until the data module is Rust-backed.
+
+Validation:
+
+- Rust unit tests for scheduler behavior.
+- Integration replay for two, three, and five local personas.
+- Slow-command metrics prove queue time and inference time separately.
+
+### PR D: Rust Model Resolver
+
+Purpose: one typed source of truth for model capability matching.
+
+Scope:
+
+- Add a request shape like `ModelRequirement`.
+- Fields include capabilities, architecture family, context window range, memory budget, modality, provider preference, and local/cloud policy.
+- Resolver returns a concrete model id, provider id, expected memory footprint, and reason.
+- No hard-coded persona model names in TS.
+
+Validation:
+
+- Qwen3.5 text model selected for text chat on local.
+- Qwen2-VL selected for vision when vision is requested and memory allows.
+- Missing model produces an actionable error, not a fallback to a random provider.
+
+### PR E: Rust Memory/RAG Admission
+
+Purpose: background cognition cannot starve chat.
+
+Scope:
+
+- Memory consolidation is a scheduled background job with a resource class.
+- Semantic compression requires explicit admission from the Rust scheduler.
+- RAG source cache is keyed by the turn planner and reused across personas.
+
+Validation:
+
+- A chat smoke with memory enabled still meets the 10s/30s gates.
+- Runtime metrics show background work deferred under chat load.
+
+### PR F: Rust Data Canonical Handles
+
+Purpose: eliminate ghost rooms and browser state authority.
+
+Scope:
+
+- Canonical room resolution moves behind the Rust data/runtime boundary.
+- Browser routing uses resolved handles only.
+- LocalStorage cannot create or select an entity id before canonical resolution.
+
+Validation:
+
+- Clearing or retaining browser storage yields the same canonical General room.
+- No deterministic `stringToUUID("General")` style fallback appears in the UI path.
+
+## Test Strategy
+
+Use VDD plus TDD:
+
+- TDD for pure Rust units: planner, model resolver, queue consolidation, capacity waves.
+- VDD for live behavior: browser chat marker, response count, latency, model used, CPU/GPU utilization.
+- Replay tests for captured failures.
+- Metrics tests for queue time, generation time, silence reasons, and background deferral.
+
+Every PR must include:
+
+- A focused Rust test when it touches runtime logic.
+- A live chat smoke result when it claims chat improvement.
+- A short note explaining whether Node authority increased, decreased, or stayed flat.
+
+## Immediate Rule
+
+Do not merge a chat-path PR to canary based only on compile success.
+
+For chat-path work, the merge gate is:
+
+- CI green.
+- Rust focused tests green.
+- Live chat smoke produces useful persona behavior, or the PR is explicitly labeled as instrumentation/guardrail and not claimed as a chat fix.

-# Helper Scripts
-
-## git-commit-docs.sh
-
-Smart commit script for documentation-only changes that skips the precommit hook.
-
-**Purpose**: When committing only documentation files (markdown, READMEs, etc.), you don't need to run the full precommit hook (which runs TypeScript compilation and tests). This script safely commits documentation-only changes using `--no-verify`.
-
-**Safety**: The script validates that ALL changes are documentation/script files before committing. If any code files (`.ts`, `.js`, `.json`) are detected, it rejects the commit and tells you to use regular `git commit` instead.
-
-### Usage
-
-```bash
-./scripts/git-commit-docs.sh "commit message here"
-```
-
-### Example
-
-```bash
-# Good: Only documentation changed
-./scripts/git-commit-docs.sh "docs: update PersonaUser architecture"
-
-# Rejected: Code files detected
-./scripts/git-commit-docs.sh "mixed changes"
-# ❌ Non-documentation files detected: PersonaUser.ts
-# This script is for documentation-only commits.
-# Use regular 'git commit' for code changes.
-```
-
-### Allowed File Types
-
-- Markdown (`.md`)
-- Text files (`.txt`)
-- README, LICENSE, CHANGELOG
-- Shell scripts (`.sh`, `scripts/` directory)
-- ReStructuredText (`.rst`)
-- AsciiDoc (`.adoc`)
-
-### When to Use
-
-✅ **Use this script when**:
-- Adding or updating documentation
-- Writing architecture design docs
-- Adding shell helper scripts
-- Updating READMEs or CHANGELOGs
-
-❌ **Use regular `git commit` when**:
-- Changing any code files (.ts, .js, .tsx)
-- Updating package.json or package-lock.json
-- Mixed documentation + code changes
-- Any changes that should run tests
-
-### Benefits
-
-- **Fast**: Skips 90+ second precommit hook for docs-only changes
-- **Safe**: Validates file types before committing
-- **Clear**: Color-coded output shows what's being committed
-- **Convenient**: Stages all documentation changes automatically

-# pusher introduced anything new. We still want the gate — just one

-#
-# How this works:
-#   1. Run ESLint, count errors against the explicit glob (`.` is
-#      "all ignored" in ESLint 9 with the current eslint.config.js).
-#   2. Read eslint-baseline.txt — the recorded "acceptable" count.
-#   3. Pass if current <= baseline. Fail if current > baseline (means
-#      this push added new violations).
-#   4. Suggest updating the baseline if current dropped substantially
-#      (cleanup is welcome, but the baseline should track real state).
-#
-# Update baseline after a real cleanup pass:
-#   cd src && npx eslint './**/*.ts' --max-warnings 0 --quiet 2>&1 \
-#     | grep -cE "error\s+" > eslint-baseline.txt

-CRITICAL TOPIC DETECTION PROTOCOL:
-
-Step 1: Check for EXPLICIT TOPIC MARKERS in the most recent message
-- "New topic:", "Different question:", "Changing subjects:", "Unrelated, but..."
-- If present: STOP. Ignore ALL previous context. This is a NEW conversation.
-
-Step 2: Extract HARD CONSTRAINTS from the most recent message
-- Look for: "NOT", "DON'T", "WITHOUT", "NEVER", "AVOID", "NO"
-- Example: "NOT triggering the app to foreground" = YOUR SOLUTION MUST NOT DO THIS
-- Example: "WITHOUT user interaction" = YOUR SOLUTION MUST BE AUTOMATIC
-- Your answer MUST respect these constraints or you're wrong.
-
-Step 3: Compare SUBJECT of most recent message to previous 2-3 messages
-- Previous: "Worker Threads" → Recent: "Webview authentication" = DIFFERENT SUBJECTS
-- Previous: "TypeScript code" → Recent: "What's 2+2?" = TEST QUESTION
-- Previous: "Worker pools" → Recent: "Should I use 5 or 10 workers?" = SAME SUBJECT
-
-Step 4: Determine response strategy
-IF EXPLICIT TOPIC MARKER or COMPLETELY DIFFERENT SUBJECT:
-- Respond ONLY to the new topic
-- Ignore old messages (they're from a previous discussion)
-- Focus 100% on the most recent message
-- Address the constraints explicitly
-
-IF SAME SUBJECT (continued conversation):
-- Use full conversation context
-- Build on previous responses
-- Still check for NEW constraints in the recent message
-- Avoid redundancy
-
-CRITICAL READING COMPREHENSION:
-- Read the ENTIRE most recent message carefully
-- Don't skim - every word matters
-- Constraints are REQUIREMENTS, not suggestions
-- If the user says "NOT X", suggesting X is a failure
-
-Time gaps > 1 hour usually indicate topic changes, but IMMEDIATE semantic shifts (consecutive messages about different subjects) are also topic changes.`

+/**
+ * EventClass — thin TS shim over the Rust event-class registry.
+ *
+ * Roadmap item L1-1 (see docs/grid/GRID-MIGRATION-ROADMAP.md).
+ * Spec: GRID-BUS-ARCHITECTURE §2.2 (continuum#1439).
+ *
+ * Native-truth-thin-SDK-per-language: declarations are stored canonically
+ * in Rust (`crate::events::event_class_registry`). This module is the
+ * thin TS wrapper:
+ *
+ *   1. Re-exports the generated wire types (single source of truth).
+ *   2. Provides `declareEventClass(name, config)` — typed wrapper that
+ *      calls the Rust `events/declare-class` IPC via `RustCoreIPCClient`.
+ *   3. Provides `getEventClass(name)` — read-through cache for the hot
+ *      `Events.emit()` path. First lookup hits the registry once via IPC,
+ *      result is cached for the lifetime of the process. Declarations
+ *      are immutable once made (conflicting re-declare throws on the
+ *      Rust side), so cache-invalidation isn't needed.
+ *   4. Provides `resolveEventChannel(name, payload)` — the airc transport
+ *      consults this at emit time. Channel resolution is payload-dependent
+ *      (ByRoomId / ByPeerId), so this can't be precomputed — but the
+ *      class config it reads from IS cached.
+ *
+ * Why local cache: `Events.emit()` is in the hot path. A round-trip to
+ * Rust on every emit would add ~1ms per event. With a local read-through
+ * cache, only the first lookup pays IPC; everything after is a Map.get.
+ *
+ * What the cache does NOT do: it does not mutate. All declarations go
+ * through the IPC. Two processes that both call `declareEventClass`
+ * with conflicting configs will get one success + one error from the
+ * Rust registry — the cache cannot mask this.
+ *
+ * Mutability semantics: declarations are append-only. Once a class is
+ * declared in Rust, identical re-declarations succeed (idempotent);
+ * conflicting re-declarations throw. The cache therefore never has to
+ * invalidate — what it has is final.
+ *
+ * Why this bypasses `Commands.execute()`: the registry is a foundational
+ * primitive — declared event classes are what `Events.emit()` consults
+ * to know whether/where to broadcast. Going through Commands.execute()
+ * here would create a layering inversion (the bus would consult event
+ * metadata that requires the bus to fetch). Direct IPC keeps the
+ * dependency one-way. The CLI/introspection surface (`grid/show-event-classes`)
+ * can be added as a separate TS Command when needed (L4 roadmap item).
+ */

-/**
- * SocialMediaRAGSource - Injects social media awareness HUD into persona RAG context
- *
- * Gives personas awareness of their social media presence:
- * - Which platform(s) they're on
- * - Karma, followers, post count
- * - Unread notifications (replies, mentions, follows)
- * - Engagement duty prompt (browse, comment, vote, follow)
- *
- * Architecture: CACHE-ONLY load() + background refresh loop.
- *
- * load() NEVER hits the DB or API — it only reads from cache.
- * A background loop (serialized, one persona at a time) handles:
- * - Credential resolution via the command system (DB lookups)
- * - Profile + notifications via Moltbook API (HTTP calls)
- * - Populating the HUD cache
- *
- * This design ensures:
- * - Zero RAG pipeline blocking (load() returns in <1ms)
- * - No thundering herd (background loop is serialized)
- * - Resilience to slow/down APIs (Moltbook has 1.4M bots, often struggling)
- * - Graceful degradation (no cache = no HUD, personas still function)
- *
- * Priority 55 - Medium. Engagement awareness is valuable but not critical.

- * PersonaMessageGate - Echo chamber prevention and post-inference validation

  *
- * Echo chamber detection is now in Rust (Gate 6 of full_evaluate).
- * This module handles:
- * - Feeding the Rust message cache (via IPC on new messages)
- * - Post-inference adequacy checks (uses TS cache for ChatMessageEntity fields + Rust IPC for similarity)
- * - Recent message cache for post-inference validation
+ * Echo chamber detection is in Rust (Gate 6 of full_evaluate); this module
+ * just subscribes to chat-message events and pushes each new message into
+ * every registered persona's Rust cognition bridge.
+ *
+ * The post-inference adequacy gate that used to live here was the
+ * Helper-only-path / TS-cognition-policy double anti-pattern Joel banned
+ * in the 2026-05-16 architecture reset — deleted in #1309 (the call-site
+ * in PersonaMessageEvaluator) + this file (the method itself). Per-persona
+ * pre-inference should-respond (Rust #1284), admission (Rust #1121 PR-4),
+ * and the resource-aware broker (#1299) are the gates now.

 /**
- * VisionInferenceProvider — Model selection + inference for vision descriptions.
+ * VisionInferenceProvider — thin shim.
  *
- * Responsibilities:
- * - Find available vision-capable models via AICapabilityRegistry
- * - Select best model (prefer local Candle, then preferred provider, then any)
- * - Build description prompts
- * - Execute multimodal inference via AIProviderDaemon
- * - Parse structured responses
+ * Pre-#1276 this file was 176 LOC owning vision-model selection,
+ * prompt construction, multimodal `AIProviderDaemon.generateText`
+ * dispatch, and response parsing. Per Joel 2026-05-15 ("if not UI/UX
+ * it is rust") and the #1248 oxidizer umbrella, all four steps moved
+ * to Rust at `../core/continuum-core/src/cognition/vision_describe.rs`
+ * and are exposed via the `cognition/vision-describe` IPC.
  *
- * Separated from VisionDescriptionService so the inference layer is swappable:
- * - Today: LLaVA via TypeScript AIProviderDaemon
- * - Future: Native Candle LLaVA in Rust (Phase D)
- * - Fallback: Cloud vision APIs (Anthropic, OpenAI)
+ * This file now exists ONLY as a thin TS-side shape preserver so
+ * `VisionDescriptionService` can keep its constructor / cache /
+ * dedup contract unchanged. Every method is a single
+ * `Commands.execute('cognition/vision-describe', ...)` call.
+ *
+ * Outlier-validation pair with codex's #1284 (AIDecisionService
+ * structured-decision shape).

+/**
+ * Multi-Persona Response Timing — chat/persona E2E regression test
+ *
+ * Codifies the bar that Mac+Windows smoke runs in #1057→#1060 surfaced:
+ * post #1062 backpressure work, the storm IS fixed (CPU stays flat) BUT
+ * fairness is broken — first-claim-wins, only ONE persona responds when
+ * N candidates are eligible. This test makes that failure mode explicit
+ * so the eventual fix has an executable green-vs-red signal.
+ *
+ * What it does
+ * ------------
+ * 1. Send ONE chat message into a room with N≥3 active personas.
+ * 2. Poll chat/export every 500ms with the probe's shortId as anchor.
+ * 3. Record when each persona's reply (replyToId === probe shortId) lands.
+ * 4. Assert:
+ *    - First persona reply within FIRST_RESPONSE_BUDGET_MS (10s per #1062)
+ *    - All eligible personas reply within ALL_RESPONSE_BUDGET_MS (30s)
+ *    - At least MIN_FAIR_RESPONSE_COUNT of N personas reply (fairness)
+ *
+ * Loud-fail buckets per #1063 / #1067 typed-bucket pattern:
+ *   probe_not_persisted             — chat/send returned ok but DB has no row
+ *   no_personas_replied             — no persona replied at all (storm-fix
+ *                                     over-corrected into total silence)
+ *   first_response_budget_exceeded  — first reply arrived after 10s
+ *   all_response_budget_exceeded    — full reply set didn't settle in 30s
+ *   fairness_violated               — only K of N replied where K < min
+ *
+ * Standing-rule alignment (#1070 / #1072):
+ * - Single attempt, no retry on failure
+ * - Loud-fail with typed bucket — operator greps result, doesn't dig
+ *   through logs
+ * - No silent fallback — the test reports what actually happened on the
+ *   user-facing surface (chat_messages → chat/export)
+ *
+ * Uses ./jtag CLI via execFile to stay decoupled from in-process JTAGClient
+ * TS surface drift; matches the chat-probe pattern operators already use.

+ * Run:

+ * Sensory Persona Roundtrip — Position 2 alpha contract test
+ *
+ * Codifies the live sensory loop a STANDARD PERSONA must satisfy per #1072:
+ * resolve a multimodal model (Chat + Vision + AudioInput + AudioOutput) →
+ * spawn LiveKitAgent into a real WebRTC room → publish a question as TTS
+ * audio + a known test image as a video frame → wait for the persona's
+ * response audio AND transcription → assert transcription mentions the
+ * image content (proves vision was wired) AND audio was published (proves
+ * TTS reached the room).
+ *
+ * Failing-loud test today; passes as Position 1 (resolver with
+ * RequirementProfile::StandardPersona) and Position 3 (Qwen multimodal GPU
+ * kernels in llama.cpp/Candle) land. The bar is the test, not the impl.
+ *
+ * Loud-fail buckets — every failure path categorized so an operator can
+ * grep the result instead of digging through logs:
+ *
+ *   no_qualified_model      — resolver returned no Standard-Persona-capable model
+ *   persona_failed_to_join  — LiveKitAgent spawn errored or never joined
+ *   no_audio_published      — persona was in room but no TTS track ever appeared
+ *   no_transcription        — STT listener never produced a transcription segment
+ *   vision_blind            — transcription text doesn't mention any image content
+ *   budget_exceeded         — first response > FIRST_RESPONSE_BUDGET_MS or
+ *                             full response > ALL_RESPONSE_BUDGET_MS
+ *
+ * Per #1070 / #1072 standing rules: NO silent CPU fallback, NO degraded-mode
+ * fallback (text-only is not a passing result), NO retry-on-failure (single
+ * attempt, fail loud, surface the bucket).
+ *
+ * Run with:
+ *   npx tsx src/tests/integration/sensory-persona-roundtrip.test.ts
+ *
+ * Prerequisites (today's failing run will report which are missing):
+ *   - LiveKit server running on $LIVEKIT_URL
+ *   - continuum-core IPC socket available
+ *   - Position 1 resolver shipped (RequirementProfile::StandardPersona)
+ *   - Position 3 Qwen multimodal kernels available on this host

+/**
+ * Chat Roundtrip Test - Precommit Validation (#1186)
+ *
+ * Sends a probe message into #general and asserts that at least one
+ * persona produces a reply within a short window. The point is to
+ * make precommit fail when the persona reply path is broken at
+ * commit time rather than after canary lands and a human notices the
+ * personas have gone silent.
+ *
+ * This is the "raise the bar past server-didn't-crash" test that
+ * Joel called out 2026-05-14: "browser ping is pretty low bar".
+ *
+ * Pass criteria:
+ *   - At least one online persona user exists in the seeded set
+ *   - Probe message is accepted by collaboration/chat/send
+ *   - Within REPLY_WINDOW_MS, a new message appears in the room
+ *     authored by an online persona
+ *
+ * Fail modes (each one is the kind of regression this test catches):
+ *   - No personas seeded (BUG-105 family)
+ *   - chat/send rejects the probe (room missing, attribution broken)
+ *   - chat/export missing the probe (write path broken)
+ *   - probe written but no persona reply within window (cognition
+ *     pipeline silently broken — the highest-value catch)

-# Rust Workers - Modular Self-Defining Registry

-## Architecture Philosophy

-**Each worker defines itself** - like Rust's Cargo workspace pattern:
-- Worker config lives WITH the worker (not in central registry)
-- Generator discovers all workers automatically
-- Adding a worker = create worker.config.ts in worker directory
-- Zero coupling - workers don't know about each other

-    ↓
-Both consumers use generated files (NEVER edit generated files!)
-```
-
-## Worker Configuration Pattern
-
-Each worker has a `worker.config.ts` in its directory:
-
-**Example**: `workers/archive/worker.config.ts`
-
-```typescript
-/**
- * Archive Worker Configuration
- *
- * Self-contained worker definition - discovered by generator
- */
-
-export default {
-  name: 'archive',
-  binary: 'workers/archive/target/release/archive-worker',
-  socket: '/tmp/jtag-archive-worker.sock',
-  args: [
-    '/tmp/jtag-command-router.sock',
-    '.continuum/jtag/data/database.sqlite',
-    '.continuum/jtag/data/archive/database-001.sqlite'
-  ],
-  description: 'Archive worker for moving old data to cold storage using Commands.execute()',
-  enabled: true
-} as const;
-
-export type ArchiveWorkerConfig = typeof import('./worker.config').default;
-```
-
-### Field Definitions
-
-- **`name`**: Worker identifier (used for process matching)
-- **`binary`**: Path to compiled Rust binary (relative to jtag root)
-- **`socket`**: Unix socket path for IPC
-- **`args`**: Array of arguments passed to worker
-- **`description`**: Human-readable description
-- **`enabled`**: Optional (default: true), set false to disable worker
-
-## Generated Files (DO NOT EDIT MANUALLY)
-
-### 1. `workers/workers-config.json` (for bash scripts)
-
-Used by start-workers.sh and stop-workers.sh. Auto-generated from worker.config.ts files.
-
-### 2. `shared/types/WorkerRegistry.ts` (for TypeScript)
-
-Provides type-safe worker names and socket paths:
-
-```typescript
-// Auto-generated types
-export const WORKER_NAMES = ['archive', 'continuum-core', 'inference-grpc'] as const;
-export type WorkerName = typeof WORKER_NAMES[number];
-
-export const WORKER_SOCKETS: Record<WorkerName, string> = {
-  'archive': '/tmp/jtag-archive-worker.sock',
-  'continuum-core': '/tmp/continuum-core.sock',
-  'inference-grpc': 'tcp://localhost:50051'
-} as const;
-
-export const ENABLED_WORKERS = ['archive', 'continuum-core', 'inference-grpc'] as const;
-```
-
-## Usage
-
-### Start Workers
-```bash
-npm run worker:start
-# Or directly:
-./workers/start-workers.sh
-```
-
-**What it does**:
-1. Reads `workers-config.json` (auto-generated)
-2. Builds all enabled workers with `cargo build --release`
-3. Kills existing workers (clean slate)
-4. Removes old socket files
-5. Starts each enabled worker with specified args
-6. Waits for socket creation
-7. Verifies all running
-
-### Stop Workers
-```bash
-npm stop
-# Or directly:
-./workers/stop-workers.sh
-```
-
-**What it does**:
-1. Reads `workers-config.json` (auto-generated)
-2. Kills all workers by name
-3. Removes all socket files (including shared sockets)
-4. Verifies stopped
-
-### Regenerate Registry
-```bash
-npx tsx generator/generate-worker-registry.ts
-```
-
-**Runs automatically during**:
-- `npm run prebuild` (before builds)
-- Development workflow
-
-## Adding a New Worker
-
-**Step 1**: Create worker directory with `worker.config.ts`
-
-```bash
-mkdir workers/my-new-worker
-```
-
-**Step 2**: Add `worker.config.ts` to worker directory
-
-```typescript
-/**
- * My New Worker Configuration
- *
- * Self-contained worker definition - discovered by generator
- */
-
-export default {
-  name: 'my-new-worker',
-  binary: 'workers/my-new-worker/target/release/my-new-worker',
-  socket: '/tmp/jtag-my-new-worker.sock',
-  args: ['--some-flag'],
-  description: 'Does something cool',
-  enabled: true
-} as const;
-
-export type MyNewWorkerConfig = typeof import('./worker.config').default;
-```
-
-**Step 3**: Run generator (or it runs automatically on prebuild)
-
-```bash
-npx tsx generator/generate-worker-registry.ts
-```
-
-**That's it!** The worker is now:
-- ✅ Discovered by generator
-- ✅ Added to workers-config.json
-- ✅ Added to WorkerRegistry.ts types
-- ✅ Available in start/stop scripts
-
-## Temporarily Disabling a Worker
-
-Edit the worker's `worker.config.ts`:
-
-```typescript
-export default {
-  name: 'data-daemon',
-  enabled: false,  // ← Disable worker
-  // ...
-} as const;
-```
-
-Then regenerate (or wait for automatic regeneration):
-```bash
-npx tsx generator/generate-worker-registry.ts
-```
-
-## Benefits of Modular Pattern
-
-✅ **Self-contained** - Worker config lives with worker code
-✅ **Zero coupling** - Workers don't know about each other
-✅ **Dynamic discovery** - File system scanning finds workers
-✅ **Type-safe** - Generated TypeScript types for compile-time safety
-✅ **Single source of truth** - worker.config.ts is canonical
-✅ **Easy to add** - Just create worker.config.ts
-✅ **Easy to disable** - Set enabled flag in config
-✅ **Self-documenting** - Each worker documents itself
-
-## Architecture Comparison
-
-### ❌ Old Pattern (Anti-Pattern)
-```typescript
-// Central registry that breaks modularity
-export const WORKERS = {
-  archive: { ... },
-  logger: { ... }
-  // Adding a worker requires editing this file
-};
-```
-
-### ✅ New Pattern (Modular)
-```typescript
-// Each worker defines itself
-// workers/archive/worker.config.ts
-export default { name: 'archive', ... };
-
-// Generator discovers all configs automatically
-// Adding a worker = just create worker.config.ts
-```
-
-## Integration with Build System
-
-The generator runs automatically during prebuild:
-
-```json
-{
-  "prebuild": "... && npx tsx generator/generate-worker-registry.ts && ..."
-}
-```
-
-This ensures:
-- Registry is always up-to-date
-- TypeScript types match worker configs
-- No manual synchronization needed
-
-## TypeScript Type Safety
-
-Use generated types in your code:
-
-```typescript
-import { WorkerName, WORKER_SOCKETS } from '@shared/types/WorkerRegistry';
-
-// Type-safe worker names
-const workerName: WorkerName = 'archive'; // ✅ Autocomplete!
-
-// Type-safe socket paths
-const socket = WORKER_SOCKETS.archive; // ✅ '/tmp/jtag-archive-worker.sock'
-
-// Compile error for invalid workers
-const invalid: WorkerName = 'nonexistent'; // ❌ TypeScript error!
-```
-
-## Requirements
-
-- **jq**: JSON processor for bash scripts
-  ```bash
-  brew install jq
-  ```
-
-## Troubleshooting
-
-### Worker won't start
-1. Check binary path in worker.config.ts exists: `ls workers/*/target/release/*-worker`
-2. Check socket isn't already in use: `ls /tmp/jtag-*.sock`
-3. Regenerate registry: `npx tsx generator/generate-worker-registry.ts`
-4. Rebuild worker: `cargo build --release` in worker directory
-
-### Worker not discovered by generator
-1. Verify `worker.config.ts` exists in worker directory
-2. Verify it exports default object with required fields
-3. Check generator output: `npx tsx generator/generate-worker-registry.ts`
-
-### Worker won't stop
-1. Manually kill: `pkill -f <worker-name>-worker`
-2. Remove socket: `rm /tmp/jtag-<worker-name>.sock`
-3. Check for orphans: `ps aux | grep worker`
-
-### Generated files out of sync
-1. Regenerate: `npx tsx generator/generate-worker-registry.ts`
-2. Or: `npm run prebuild` (regenerates everything)
-
-### TypeScript compilation errors after adding worker
-1. Regenerate registry: `npx tsx generator/generate-worker-registry.ts`
-2. Restart TypeScript server in your editor
-3. Check `shared/types/WorkerRegistry.ts` was updated
-
----
-
-**Bottom line**: Workers define themselves, generator discovers them, both bash and TypeScript use generated configs. Add workers by creating worker.config.ts, not editing central registries!

-//! AI Provider Module - Unified AI Integration Layer in Rust
-//!
-//! Provides adapter-based AI provider system similar to ORM adapter pattern.
-//! Supports multiple providers with consistent interface and tool calling.
-//!
-//! Architecture:
-//! - `adapter.rs` - The adapter trait (like StorageAdapter for ORM)
-//! - `types.rs` - Shared types including tool calling
-//! - `openai_adapter.rs` - OpenAI-compatible providers (DeepSeek, Together, Groq, etc.)
-//! - `anthropic_adapter.rs` - Anthropic Claude models
-//!
-//! Usage:
-//! ```rust
-//! let mut registry = AdapterRegistry::new();
-//! registry.register(Box::new(OpenAICompatibleAdapter::from_registry("deepseek")), 0);
-//! registry.register(Box::new(AnthropicAdapter::new()), 1);
-//! registry.initialize_all().await?;
-//!
-//! let (provider_id, adapter) = registry.select(None, Some("deepseek-chat")).unwrap();
-//! let response = adapter.generate_text(request).await?;
-//! ```

-//! Shared Cognition — the objective-analysis + specialty-render split.
-//!
-//! Native-truth Rust core for the shared-cognition pipeline. The
-//! TypeScript layer is a thin wrapper (IPC mixin + generated command
-//! scaffolds + auto-generated types via ts-rs). All logic — analysis
-//! pipeline, response orchestration, lever evaluation — lives here.
-//!
-//! Architecture: see `docs/architecture/SHARED-COGNITION.md`. Thesis:
-//! today each persona independently rebuilds the objective picture
-//! (what the message means, what RAG matters) before contributing
-//! their specialty slice. Splitting into one shared analysis (cheap,
-//! once per message) + N short specialty renders (one per persona)
-//! drops the duplicate work without losing the distinct perspectives.
-//!
-//! Why Rust: SIMD scoring, true concurrency for parallel responder
-//! evaluation, kernel-level memory rules for the cache. None of this
-//! is expressible in TS without hand-waving.
-//!
-//! Same module-shape pattern as `rag/`:
-//!   - `mod.rs`     — module surface
-//!   - `types.rs`   — Rust source-of-truth types, ts-rs auto-emit to
-//!                    `shared/generated/cognition/` (TS gets the schema
-//!                    for free; nobody hand-writes TS types for these)
-//!   - `shared_analysis.rs`     — analysis pipeline (the verb that
-//!                                produces `SharedAnalysis`)
-//!   - `response_orchestrator.rs` — per-persona relevance scoring +
-//!                                  decision (the verb that produces

-//! `MetalMonitor` — `GpuMonitor` impl for macOS.
-//!
-//! Per §12 of `docs/architecture/PERSONA-CONTEXT-PAGING.md`: the prior
-//! `GpuMemoryManager`'s Metal path treated `recommendedMaxWorkingSetSize`
-//! as live free memory. It isn't — it's a STATIC lifetime hint from the
-//! driver about the total budget the GPU can address. Process pressure
-//! and system pressure both went unreported. A video game grabbing VRAM
-//! never registered.
-//!
-//! This monitor distinguishes the four signals the policy actually needs:
-//!
-//! - `total_bytes` → Metal `MTLDevice.recommendedMaxWorkingSetSize` (still
-//!   the right source for TOTAL — only wrong as a "free" proxy).
-//! - `free_bytes` → Mach `host_statistics64(HOST_VM_INFO64)` summing
-//!   free + speculative + inactive page counts × page size. System-wide
-//!   free; the signal that catches "another app grabbed our headroom."
-//! - `process_bytes` → Mach `task_info(mach_task_self(), TASK_VM_INFO)`
-//!   → `phys_footprint`. This process's authoritative footprint, including
-//!   unified-memory GPU buffers mapped into our address space.
-//! - `utilization` / `temperature_c` / `power_watts` → IOReport.framework.
-//!   No maintained Rust crate; requires our own Objective-C runtime shim.
-//!   Phase 2.0a-IOReport ships separately. For now these return defaults
-//!   (0.0 / None) so the policy can still rely on memory-pressure signals
-//!   — the load-bearing signal — without blocking on the IOReport work.
-//!
-//! Module layout (Joel's modularize-to-simplify principle):
-//!
-//!   - `mod.rs` (this file) — `MetalMonitor` struct + `GpuMonitor` impl +
-//!     tick spawn. The policy-facing surface.
-//!   - `mach_ffi` — Mach VM FFI (structs, type aliases, raw read fns).
-//!     Independently testable; separation caught the clashing-extern bug
-//!     from the original mono-file version by making the FFI layer its

-//! Model Backends — Unified Interface for ALL Local Inference
-//!
-//! Every local model (GGUF quantized, safetensors BF16/FP32) implements the
-//! `ModelBackend` trait. The model file is the single source of truth for
-//! capabilities: context_length, EOS tokens, architecture.
-//!
-//! Adding a new model format/architecture:
-//!   1. Create `backends/<arch>_<format>.rs` implementing `ModelBackend`
-//!   2. Add `pub mod <name>;` below
-//!   3. Add factory function or match arm in load functions
-//!
-//! The trait abstracts: forward pass, prefill strategy, context length,
-//! EOS tokens, tokenization, cache management, and LoRA support.
-//! One `generate()` function works with ANY backend.

-//! Per-component memory footprint registry — "what are we made of?"
-//!
-//! Per §13 of `docs/architecture/PERSONA-CONTEXT-PAGING.md`: GpuMonitor
-//! (§12) tells the policy WHAT pressure looks like; the registry tells
-//! it WHAT to do about it. Without per-component attribution the policy
-//! knows "we're at 90% of process limit" but has no idea WHICH of N
-//! things in our process is biggest, cheapest to spill, or worth
-//! keeping hot.
-//!
-//! Every allocation site (KV slots, LoRA adapters, model weights,
-//! render buffers, tokenizer caches, audio/video pipelines) reports
-//! bytes via a single DashMap keyed on (persona, recipe, backend,
-//! resource type, residency). Reporting is unconditional and cheap;
-//! no `#[cfg]`, no platform branches.
-//!
-//! The registry's `cheapest_eviction_for` is what makes paging real:
-//! given "free X bytes," it returns a plan picking the lowest-cost
-//! combination of evictable entries. Cost-driven, not type-prioritized.
-//!
-//! Module layout:
-//!
-//! - `mod.rs` (this file) — `FootprintRegistry` impl, global singleton,
-//!   integration tests across the registry's behavior.
-//! - `types.rs` — pure data shapes (ResourceType, FootprintKey,
-//!   FootprintEntry, EvictionPlan, RegistryHealth, RegistrySnapshot)
-//!   + key constructors. Independently testable for layout/equality.
-//! - `costs.rs` — spill/reload heuristics per ResourceType + tests for
-//!   policy invariants (KV cheaper than ModelWeights to spill, etc.).
-//!   The file Phase 4.0 telemetry will replace as measurements mature.

-//! `LlamaCppAdapter` — implements `AIProviderAdapter` by wrapping our
-//! in-process `LlamaCppBackend` (the bundled `llama` crate, statically
-//! linked against the vendored llama.cpp Metal/CUDA build).
-//!
-//! Why this exists:
-//!
-//! Docker Model Runner (DMR) ships a containerized llama-server. On Mac
-//! the container's Metal toolchain has been failing to compile the
-//! tensor-API source on M5/Apple10 hardware (verified 2026-04-19, log:
-//! `ggml_metal_library_init_from_source: error compiling source` →
-//! `has tensor = false`). Result: M5 inference at 22 tok/s — slower
-//! than M1 at 27 tok/s on the same model. The cripple is in DMR's
-//! container build, not in llama.cpp itself.
-//!
-//! This adapter bypasses DMR entirely — loads the GGUF in-process via
-//! our newer vendored llama.cpp build, which compiles Metal correctly
-//! against the host toolchain. Empirical win: 33 tok/s vs DMR's 22 tok/s
-//! on the same hardware (50% improvement, smoke test in
-//! `tests/llamacpp_metal_throughput.rs`).
-//!
-//! Other wins from owning the inference call directly:
-//! - No HTTP hop (in-process call vs localhost roundtrip)
-//! - Full control of `n_gpu_layers`, batch sizes, sampling
-//! - Direct access to LoRA hot-swap via `LlamaCppBackend::ensure_adapter`
-//! - Metal command-buffer timing available for real GPU-utilization
-//!   metrics (planned follow-up — addresses "we can't even see what
-//!   percent GPU was used" observability gap)
-//!
-//! Coexistence with DMR adapter:
-//! - Both registered. This adapter gets HIGHER priority (lower number)
-//!   so local Mac inference flows here first.
-//! - DMR remains the fallback for: cases where in-process load fails,
-//!   non-Mac platforms, or operators who prefer the container path.

-//! Qwen3.5 GGUF Backend — Hybrid DeltaNet + Attention architecture.
-//!
-//! Qwen3.5 uses a mix of two layer types:
-//!   - **Full Attention** (every 4th layer: 7, 11, 15, 19, 23, 27, 31): Standard
-//!     multi-head attention with separate Q/K/V projections, GQA, KV cache.
-//!   - **DeltaNet** (all other layers): Linear attention with state-space recurrence.
-//!     Uses fused QKV, gating, SSM decay/update, and short convolution.
-//!
-//! Both layer types share the same FFN (SwiGLU) and use partial RoPE — only the
-//! first `rope_dim` dimensions of each head get rotary embedding.
-//!
-//! Key differences from Llama/Qwen2:
-//!   - `rope_dim` (64) != `head_dim` (256) — partial RoPE
-//!   - `post_attention_norm` instead of `ffn_norm`
-//!   - DeltaNet layers have SSM tensors: ssm_a, ssm_alpha, ssm_beta, ssm_conv1d, ssm_dt, ssm_out
-//!   - Attention gating on DeltaNet layers: sigmoid(gate) * output
-//!   - QK norm on DeltaNet layers (attn_q_norm, attn_k_norm)

-//! Bevy Headless Avatar Renderer
-//!
-//! A single Bevy app instance renders all AI persona avatars simultaneously.
-//! Each avatar gets its own RenderLayer + Camera + render target texture.
-//! GPU readback delivers RGBA frames via crossbeam channels to LiveKit video loops.
-//!
-//! Architecture:
-//!   BevyAvatarSystem (singleton)
-//!     └── Bevy App (dedicated OS thread)
-//!           ├── Avatar slot 0: Camera → RenderTarget → Readback → channel
-//!           ├── Avatar slot 1: Camera → RenderTarget → Readback → channel
-//!           ├── ...
-//!           └── Avatar slot 15: Camera → RenderTarget → Readback → channel
-//!
-//! Performance: 16 avatars × 640×360 @ ~7fps effective readback (15fps Bevy tick).
-//! On Apple Silicon (shared memory + GPU bridge), readback is zero-copy IOSurface.
-//!
-//! ## Module Structure
-//!
-//! - `api` — BevyAvatarSystem singleton, public methods
-//! - `app` — Bevy App setup and system registration
-//! - `commands` — AvatarCommand processing
-//! - `readback` — GPU readback management
-//! - `setup` — Render slot allocation, readback entity spawning
-//! - `stats` — Memory stats, load monitoring, light visibility
-//! - `animation/` — Per-concern animation systems (blinking, breathing, etc.)
-//! - `types` — All components, resources, enums, structs
-//! - `scene/` — Scene graph, room, animation config
-//! - `skeleton` — Bone discovery, T-pose fix, scene tree helpers
-//! - `vrm` — VRM extension parsing (blend shapes, humanoid bones, lookAt)

-/// `__cxa_finalize_ranges`). Reason: the process holds raw pointers to
-/// llama.cpp objects (Model, Context, LoraAdapter, MtmdContext) whose Rust

-/// and SIGABRT. The crash signature is:
-///   `tokio-rt-worker → __cxa_finalize_ranges → continuum-core destructor → abort()`
-///
-/// `_exit` skips all atexit handlers + Rust drops + libc cleanup → kernel
-/// reclaims memory + closes FDs + unmaps mmaps. Buffered stdout would be
-/// lost, but tracing writes to stderr per-line and we eprintln! the
-/// shutdown message before exiting, so no diagnostic loss in practice.

-//! AgentModule — Autonomous AI coding agent with structured tool calling.
-//!
-//! Unlike sentinels which are script-based, agents:
-//! 1. Have STRUCTURED TOOL DEFINITIONS - LLM sees proper tool schemas
-//! 2. Use TOOL CALLING protocol - Real structured output parsing
-//! 3. Maintain FULL CONTEXT - Conversation history
-//! 4. ITERATE until done - Build, test, fix loop
-//! 5. Handle REAL TASKS - Multi-file changes, codebase exploration
-//!
-//! Commands:
-//! - agent/start: Start an autonomous agent (returns handle immediately)
-//! - agent/status: Get agent status and progress
-//! - agent/stop: Stop a running agent
-//! - agent/list: List all agents (running and completed)
-//!
-//! Events emitted:
-//! - agent:{handle}:progress - Progress updates
-//! - agent:{handle}:action - Tool calls and results
-//! - agent:{handle}:complete - Agent finished (success or failure)
-//!
-//! Priority: Normal — agents are long-running background tasks.

-//! CognitionModule — per-persona cognitive state + text analysis IPC.
-//!
-//! Unified per-persona state: one DashMap<Uuid, PersonaCognition> holds all
-//! cognitive state (engine, inbox, rate limiter, sleep, adapters, genome).
-//! Single lock acquisition per command. Related state is cache-local.
-//!
-//! Stateless text analysis commands (similarity, validation, mentions, cleaning)
-//! use no per-persona state.
-//!
-//! Commands:
-//! - `cognition/create-engine`: Create all per-persona cognitive state
-//! - `cognition/calculate-priority`: Priority scoring
-//! - `cognition/fast-path-decision`: Fast-path respond/skip decision
-//! - `cognition/enqueue-message`: Enqueue message to persona inbox
-//! - `cognition/get-state`: Get persona cognitive state
-//! - `cognition/full-evaluate`: Unified 6-gate evaluation (replaces 5 TS gates)
-//! - `cognition/track-response`: Track response for rate limiting
-//! - `cognition/set-sleep-mode`: Set voluntary sleep mode
-//! - `cognition/configure-rate-limiter`: Configure rate limiter params
-//! - `cognition/select-model`: 4-tier model priority chain
-//! - `cognition/sync-adapters`: Sync adapter registry from TypeScript
-//! - `cognition/genome-activate-skill`: LRU eviction + skill activation
-//! - `cognition/genome-sync`: Sync full adapter state from TypeScript
-//! - `cognition/genome-state`: Get current genome paging state
-//! - `cognition/genome-evict-under-pressure`: Drive eviction to target pressure (broker lever)
-//! - `cognition/check-adequacy`: Batch adequacy check
-//! - `inbox/create`: Create persona inbox (alias for create-engine)
-//!
-//! Uses `Params` helper for typed parameter extraction.

-//!
-//! Handles: embedding/generate, embedding/model/load, embedding/model/list,
-//!          embedding/model/info, embedding/model/unload
-//!
-//! Benefits of native embedding:
-//! - No network overhead (~5ms per embedding)
-//! - Batch processing (100 texts in ~100ms)
-//! - No external service dependency
-//! - True parallelism via ONNX Runtime
-//!
-//! Priority: Normal — embedding is not time-critical like voice.

-//! Sentinel Module — Concurrent, fault-tolerant build/task execution with pipeline support
-//!
-//! Sentinels are autonomous agents that can run builds, tests, and other
-//! long-running processes with proper isolation and logging.
-//!
-//! Key Design Principles:
-//! - **Process Isolation**: Each sentinel runs in a child process (crash isolation)
-//! - **Non-blocking**: Heavy processes (Xcode, cargo) don't block the runtime
-//! - **Fault Tolerant**: One sentinel failure doesn't cascade to others
-//! - **Concurrent**: Multiple sentinels can run in parallel
-//! - **Observable**: All output streamed to logs in real-time
-//! - **Event-driven**: Emits sentinel:{handle}:log events for real-time streaming
-//! - **Pipeline Support**: Multi-step pipelines with LLM, conditions, loops

-//! PressureBroker — cross-pool eviction orchestration.
-//!
-//! Phase 7 of the resource architecture (RESOURCE-ARCHITECTURE.md).
-//!
-//! The PagedResourcePool primitive is the per-resource brain. The broker
-//! is the cross-resource brain: one orchestrator that reads pressure
-//! from every registered pool, decides which to relieve, and pulls the
-//! eviction lever. Same broker is the future home of recipe-aware
-//! priority arbitration, ML-policy-driven tiering decisions, and
-//! eventually LLM-mediated control for novel pressure situations.
-//!
-//! This commit lands the trait + broker scaffolding + tick loop. Pools
-//! register themselves as `PressureSource` implementors; the broker
-//! aggregates pressure on a periodic tick; when global pressure crosses
-//! threshold, eviction fires on the highest-pressure pool first.
-//!
-//! What's NOT in this commit (intentionally — separate phases):
-//!   - ML/LLM policy hook (the broker exposes the lever; the brain
-//!     plugs in later via PressureSource priority overrides)
-//!   - Recipe activation/deactivation hooks (Phase 9)
-//!   - Cross-machine pressure (grid-level paging is its own layer)
-//!
-//! See: docs/architecture/RESOURCE-ARCHITECTURE.md (Phase 7)

-//! PagedResourcePool — the unified paging primitive.
-//!
-//! Same shape used by every resource that needs paging:
-//!   - LoRA adapter weights (genome registry adopts this)
-//!   - KV cache pages (PagedAttention via vllm-metal handles natively;
-//!     thin wrapper exposes its semantics through the same interface)
-//!   - MoE expert weights (when MoE forge ships)
-//!   - Model weights (multiple loaded models per host)
-//!   - Embedding vectors (content-addressed dedup; fixes the 0/64 hit rate)
-//!   - Memory recall results (TieredMemoryCache reformulation)
-//!
-//! Each consumer hand-rolled its own implementation today. The drift between
-//! them IS the bug — different pressure interpretations, eviction policies,
-//! single-flight handling. This primitive is the shared shape.
-//!
-//! Operations:
-//!   - `get(k)` — L1 hit, returns owned value if cached, no load
-//!   - `load_or_share(k, loader)` — single-flight load + cache; concurrent
-//!     calls for the same key share ONE loader invocation
-//!   - `pin(k)` — reference-counted hold; entry not evicted while pinned
-//!   - `evict(k)` — forced drop regardless of pin count
-//!   - `stats()` — pressure, hit rate, count for the PressureBroker
-//!
-//! Properties:
-//!   - **Thread-safe** by default (parking_lot::RwLock + tokio Mutex for
-//!     the inflight map). Built for the multi-persona concurrent case.
-//!   - **Required config** — no Option<>, every choice declared explicitly
-//!     per Joel's required-not-optional discipline.
-//!   - **Reject-promise cleanup** — failed loads don't poison the cache;
-//!     the inflight slot is removed on both Ok and Err.
-//!   - **Pressure-driven eviction** — `maybe_evict` triggers when occupancy
-//!     exceeds `max_bytes`, drops unpinned entries by eviction priority
-//!     (LRU default) until back to 75% of capacity.
-//!

-//! PersonaAllocator — single source of truth for persona creation decisions.
-//!
-//! Input:  GPU stats from GpuMemoryManager, list of available API key env var names
-//! Output: Vec<PersonaAllocation> — which personas to create, with what model and VRAM budget
-//!
-//! This replaces the TS-side getAvailablePersonas() + detectGpu() + selectLocalModel().
-//! Rust owns the decision; TypeScript calls `persona/allocate` IPC and uses the result.
-//!
-//! Allocation strategy — per-persona tiered model selection:
-//!   32GB+ CUDA (5090):       CodeReview(32B/20GB) + Teacher(14B/9GB) + Helper(8B/5GB) + Local(3B/3GB)
-//!   24-31GB Metal (M-Max):   Teacher(14B/9GB) + Helper(8B/5GB) + Local(3B/3GB)
-//!   16-23GB Metal (M-Pro):   Teacher(8B/5GB) + Helper(3B/3GB) + Local(3B/3GB)
-//!   8-15GB (MacBook Air):    Helper(3B/3GB)
-//!   <8GB / CPU:              Helper(3B/3GB, CPU mode)
-//!   + per cloud API key:     One persona per key (0GB VRAM)

-//! Cognition I/O — value objects describing inputs to the cognition
-//! layer.
-//!
-//! `Signal` is the host's raw event (chat message, video frame, code
-//! diff, game tick, autonomous-loop poke). `PersonaContext` is the
-//! per-persona stable state (identity, model, capabilities, history,
-//! room membership). `build_respond_input` projects these into the
-//! `RespondInput` the cognition layer consumes.
-//!
-//! # Why this is data + a free function (not a trait)
-//!
-//! Earlier shape: a `Recipe` trait with per-domain implementations
-//! (`ChatRecipe`, `VisionRecipe`, …) baked into Rust. That shape was
-//! wrong for two reasons:
-//!
-//! 1. Recipes are data. They live as JSON `RecipeEntity` rows,
-//!    authored by users / AIs / shared via the grid. Hardcoding a
-//!    Rust trait for each domain is the kernel-level commands +
-//!    data-driven recipes anti-pattern (CLAUDE.md): commands are
-//!    primitives, recipes are the data the executor walks.
-//! 2. The projection from `(Signal, PersonaContext) → RespondInput`
-//!    is one canonical mapping, not a per-domain one. Earlier
-//!    `Recipe::build_input` implementations all did the same
-//!    field-by-field projection with minor signal-kind validation
-//!    in front. Wrapping that in a trait inflated it.
-//!
-//! The Rust-native pipeline executor (designed in
-//! `docs/architecture/RECIPE-EXECUTION-RUNTIME.md`) walks recipe
-//! data, dispatches kernel commands, and uses these value objects
-//! to feed the cognition layer at the appropriate pipeline step.
-//! That's the right shape; this file contains the value objects and
-//! the canonical projection used by the executor.

-//! Unified Persona Evaluator — ALL pre-response gates in one call.
-//!
-//! Consolidates 5 sequential TypeScript gates + Rust fast-path into a single
-//! `full_evaluate()` function. One IPC call, <1ms, zero GC.
-//!
-//! Gate order (short-circuits on first SILENT):
-//! 1. Sleep mode — checks SleepMode + topic similarity (persona's own opt-out)
-//! 2. Self-message — infinite loop prevention (inside fast_path)
-//! 3. Fast-path decision — delegates to PersonaCognitionEngine::fast_path_decision
-//!
-//! Note: response_count is collected as a SIGNAL (LLM sees it in social_signals
-//! and can self-quiet if a conversation is getting too noisy) but is NOT a hard
-//! gate. Local models have no cost; cloud rate limits belong at the provider
-//! layer (their billing + RPS quotas), not as a hardcoded 50-message veto here.
-//! The previous response_cap gate was a cloud-provider concern that leaked onto
-//! every persona including local ones — removed to honor "LLM decides, not dumb
-//! heuristics" (the philosophy this module already preaches).
-//!
-//! Types exported to TypeScript via ts-rs.

-//! Per-turn cognition recorder. Writes a self-contained turn capture
-//! (request + response + trace) from inside `respond()`, so EVERY host
-//! that links the persona library — TS server, Unreal plugin, Swift
-//! Vision Pro app, raw Rust binary — gets recordings for free without
-//! depending on the host language for the recording mechanism itself.
-//!
-//! # Why this exists Rust-side
-//!
-//! Before this module, the fixture write lived in
-//! `system/user/server/modules/PersonaResponseGenerator.ts` — fine for
-//! the chat surface (Node host), useless for any non-Node embedding.
-//! "If I wanted to put a persona inside an Unreal video game or AR/VR
-//! system on Vision Pro, I'd want to be able to do so without Node"
-//! — Joel, 2026-04-22.
-//!
-//! The recorder lives next to `respond()` so the act of running a
-//! cognition turn is the act of recording it. Hosts can opt OUT via
-//! the disable env var if they want to throw away recordings (perf
-//! tests, ephemeral hosts), but the default is "always record" — F1
-//! cars don't ship without telemetry either.
-//!
-//! # Format
-//!
-//! JSON, one file per turn at:
-//!
-//!   `~/.continuum/fixtures/persona-respond/<persona>-<msgid>-<ts>-rust.json`
-//!
-//! The `-rust` suffix distinguishes Rust-emitted captures from the
-//! TS-emitted captures (which carry additional outer context — the
-//! original chat message, the full RAG conversationHistory, etc.).
-//! Both can coexist in the same dir, joined by `messageId`. As Phase
-//! B/C land, RAG construction migrates Rust-side and the TS capture
-//! disappears; the Rust capture becomes the single artifact.
-//!
-//! Schema (`schemaVersion: 1`):
-//! - `capturedAtMs` — wall-clock when the turn finished
-//! - `personaId`, `personaName`, `messageId`, `roomId`, `model` —
-//!   identity for joining + filtering
-//! - `rustRequest` — echo of the input that drove the call
-//! - `rustResponse` — `PersonaResponse` returned
-//! - `cognitionTrace` — per-seam timing + metadata
-//!
-//! # FIFO trim
-//!
-//! The fixture dir is FIFO-trimmed at `FIXTURE_CAP_PER_DIR` (200)
-//! entries. Recent slice without unbounded growth — replay tests run
-//! against whatever's there; older captures drop when the cap fills.
-//! Same policy the TS writer uses, kept aligned so neither side
-//! produces a runaway dir.
-//!
-//! # Failure mode
-//!
-//! Recording is BEST-EFFORT. A failure to write the fixture must NOT
-//! propagate as a cognition error — the persona's response is the
-//! product, the recording is observability. Failures log a warning
-//! and the turn returns its real result.

-//! Per-persona response orchestration in Rust. The Rust replacement for
-//! `PersonaResponseGenerator.ts` — owns the cognitive verb of "this
-//! persona, given this message in this room, produces this response."
-//!
-//! See docs/architecture/SHARED-COGNITION.md for the architectural
-//! picture and docs/architecture/PERSONA-COGNITION-RUST-MIGRATION.md
-//! for the migration discipline this module is the first rung of.
-//!
-//! Pipeline (per persona, per inbound message):
-//!
-//!   1. cognition::analyze(...)   — shared, cached. Provides the
-//!                                  prompt-time hint map (suggested
-//!                                  angles per specialty) but does NOT
-//!                                  gate response. Informational only.
-//!   2. prompt_assembly::build(...) — persona-specific prompt: voice,
-//!                                    LoRA-rendered specialty, RAG
-//!                                    context interleaving, native
-//!                                    multimodal attachment per the
-//!                                    persona's resolved capabilities.
-//!   3. ai_provider::generate_text(...) — inference. The persona's
-//!                                        own model decides what to
-//!                                        say. Personas emulate
-//!                                        humans — they choose for
-//!                                        themselves whether to
-//!                                        engage; no external scorer
-//!                                        vetoes them.
-//!   4. strip_thinks_emit_events(...) — extract <think>...</think>
-//!                                       blocks, emit them as
-//!                                       cognition:think-block events
-//!                                       for the (future) hippocampus
-//!                                       to consume, return clean
-//!                                       speech for posting.
-//!   5. Return Spoke { text, ... } with timing + diagnostic fields.
-//!      Silent is still a valid return when the persona's own model
-//!      produces empty / "I'll pass" output — but it's the persona's
-//!      cognitive output, not a pre-inference veto.
-//!
-//! Why this is in Rust (not just a port):
-//!   - Cognition is where the mind/machine line gets drawn — concurrency
-//!     primitives matter (Joel, 2026-04-19).
-//!   - SharedAnalysis cache lives here; needs lock-free DashMap for
-//!     concurrent personas hitting the same message.
-//!   - Per-persona renders run in parallel tokio tasks; Node's single
-//!     event loop blocks every persona on every other persona's
-//!     inference call.
-//!   - <think> parsing is a hot path on every response; regex/str
-//!     manipulation in Rust is ~100x what TS does on the same input.

-//! `CognitionTrace` — per-turn time-series of every seam a persona's
-//! `respond()` call passes through.
-//!
-//! # Why this exists
-//!
-//! "We need our mechanic's meters, EE's oscilloscope, programmer's test
-//! bench, F1 racer's re-simulation, on every persona, isolatable at any
-//! level so we can replay or even use this to break and train."
-//! — Joel, 2026-04-22.
-//!
-//! `CognitionTrace` is the spine of that. Each seam in the cognition
-//! pipeline (analyze, prompt assembly, inference, post-process)
-//! appends a `TraceSeam` with its name, start time, duration, and
-//! seam-specific metadata. The completed trace serializes into the
-//! turn record alongside the request/response, so a captured trace +
-//! the captured request reconstructs WHAT happened AND HOW LONG each
-//! step took, no live system needed.
-//!
-//! # Design
-//!
-//! - **Value object, not a service**. Created per call, dropped per
-//!   call. No global state, no async machinery, no locks.
-//! - **Thread-affined**. Owned by the cognition turn that created it.
-//!   `respond()` is a `tokio::task` per persona; no two tasks share a
-//!   trace. Borrow it `&mut` through helper functions; no `Arc<Mutex>`
-//!   needed, no contention.
-//! - **Open-vocabulary metadata**. Each seam carries a
-//!   `serde_json::Value` of seam-specific fields (analyze records
-//!   `from_cache: bool`, inference records `model: String`, etc.).
-//!   Adding a new field doesn't touch the trace type.
-//! - **Source-time strings for seam names**. `&'static str` instead of
-//!   enum so new seams (recipe-specific later) don't require enum
-//!   churn. Cost: typo-by-string, mitigated by the seam-name constants
-//!   below.
-//!
-//! # Seam name conventions
-//!
-//! Use the constants in this module (`SEAM_*`) when emitting from the
-//! known cognition path. Recipe-specific seams (added in Phase B+)
-//! supply their own string at the call site.

-//! Defines the length-prefixed binary framing protocol in ONE place.
-//! All integration tests that communicate with the continuum-core IPC server
-//! MUST use this module instead of hand-rolling socket reads.
-//!
-//! ## Protocol (server → client)
-//!
-//! Requests:  newline-delimited JSON (client → server)
-//! Responses: length-prefixed binary framing (server → client)
-//!
-//! ```text
-//! [4 bytes u32 BE: payload length][payload bytes]
-//! ```
-//!
-//! Payload variants:
-//! - **JSON**: entire payload is valid UTF-8 JSON
-//! - **Binary**: `[JSON header bytes][\0 separator][raw binary data]`
-//!
-//! The `\0` separator is unambiguous — serde_json encodes null chars as `\u0000`.

-/// behavior. llama.cpp's `llama_tokenize` is smart enough NOT to inject
-/// the GGUF's declared BOS when the rendered prompt already starts with
-/// a special structural token (chatml `<|im_start|>` in our case). So
-/// `add_bos=true` and `add_bos=false` produce IDENTICAL output for
-/// chatml-rendered prompts.
-///
-/// Validated 2026-04-21 (TDD/VDD): wrote this test expecting the
-/// asymmetry to confirm "add_bos=true injects comma." Test FAILED
-/// because BOTH variants produced position-0 = id 248045 (`<|im_start|>`).
-/// Hypothesis ruled out without running inference. Test now asserts the
-/// ACTUAL behavior (identical output) so any future change that breaks
-/// this invariant gets caught.

-/// The bug we were chasing is downstream of tokenization — sampler,
-/// scheduler, or model behavior on the specific prompt content.

-//! llama — our owned substrate for local LLM inference.
-//!
-//! Vendors llama.cpp as a git submodule, builds it via cmake, exposes a safe
-//! Rust API. One binary, no external process, cross-platform via features.
-//!
-//! Features:
-//!   - `metal`: Apple Silicon GPU (Mac) — REQUIRED on macOS
-//!   - `cuda`: NVIDIA GPU (Linux + Windows/WSL)
-//!   - default: CPU with BLAS
-
-// ── Compile-time guard: no silent CPU-only Mac builds ─────────────────
-// If you build this crate on macOS without `--features metal`, llama.cpp
-// is compiled with GGML_METAL=OFF (per build.rs). That produces a library
-// that SILENTLY FALLS BACK to CPU inference regardless of what
-// `n_gpu_layers` is set to at runtime — no warning, no error, just a CPU
-// model that runs ~20× slower than it should (12 tok/s instead of 60+
-// tok/s on M-class Metal). This class of bug cost roughly a week of
-// debugging (2026-04) because the runtime config path LOOKS correct:
-// the Rust code passes `n_gpu_layers = -1` faithfully all the way through
-// the FFI, but Metal simply doesn't exist in the compiled static library.
-//
-// Fail LOUD at compile time. Any Mac build path (cargo, Dockerfile, CI
-// matrix, `npm start`) that reaches here without the feature flag now
-// errors out with a clear message instead of shipping a broken binary.
-// If you genuinely need CPU-only on macOS (rare — testing harness, x86
-// cross-compile), delete this guard deliberately with a commit message
-// justifying it. Don't silently pass a flag that removes it.

+# tools/ — dev tooling (not shipped)
+
+Code generators, build scripts, and infrastructure helpers. Nothing
+under `tools/` is part of any deployed binary or app — it exists to
+support the day-to-day work of moving code through `core/`, `client/`,
+`sdk/`, and `apps/`.
+
+| Dir | Purpose |
+|-----|---------|
+| `generator/` | Code generators — Command specs → typed scaffolds, entity schemas → Rust + TS, daemons, audio constants, etc. |
+| `scripts/` | Dev / build / CI helper scripts (TS, JS, shell) — install, start, stop, hooks, seeding, fixtures. |
+
+Repo-root `scripts/` (e.g. `scripts/push-image.sh`) is separate and holds
+release / orchestration scripts, not dev tooling.

+**Precommit too slow or failing because the worktree is stale?**
+
+- The validation is intentional.
+- Fix missing dependencies, submodules, generated files, or hook bugs instead
+  of bypassing the hook.
+- For docs-only changes, run focused docs checks first, then use normal
+  `git commit`.
+- If a hook is wrong, fix the hook in its own PR. Do not use `--no-verify`.

+# Helper Scripts
+
+## Documentation Commits
+
+Documentation-only changes still use normal git hooks.
+
+**Purpose**: Keep docs fast to validate without creating a bypass culture.
+Run focused docs checks before committing, then commit normally so the repository
+uses the same validation path for humans and agents.
+
+`--no-verify` is forbidden. If hooks fail on a docs-only change because a
+worktree is stale, fix that worktree, dependency, submodule, generated-file, or
+hook problem instead of bypassing validation.
+
+### Usage
+
+```bash
+npx markdownlint-cli2 "docs/**/*.md"
+git diff --check
+git add docs/path/to-file.md
+git commit -m "docs: update architecture note"
+```
+
+### Example
+
+```bash
+# Good: Only documentation changed
+npx markdownlint-cli2 docs/architecture/PERSONA-AS-RUST-LIBRARY-PLAN.md
+git diff --check
+git commit -m "docs: update PersonaUser architecture"
+
+# Rejected by review/process: any command that bypasses git hooks
+```
+
+### Allowed File Types
+
+- Markdown (`.md`)
+- Text files (`.txt`)
+- README, LICENSE, CHANGELOG
+- Shell scripts (`.sh`, `scripts/` directory)
+- ReStructuredText (`.rst`)
+- AsciiDoc (`.adoc`)
+
+### When to Use Focused Docs Checks
+
+✅ **Run focused docs checks when**:
+- Adding or updating documentation
+- Writing architecture design docs
+- Adding shell helper scripts
+- Updating READMEs or CHANGELOGs
+
+❌ **Run the full relevant validation when**:
+- Changing any code files (.ts, .js, .tsx)
+- Updating package.json or package-lock.json
+- Mixed documentation + code changes
+- Any changes that should run tests
+
+### Benefits
+
+- **Fast local signal**: Markdown lint and whitespace checks catch doc
+  mistakes before hooks.
+- **Same validation path**: Normal git hooks still run.
+- **No hidden escape hatch**: Agents cannot silently skip validation for convenience.

+#   metal` (macOS) or `--features cuda` (Linux+Nvidia) so the build refuses to
+#   produce a CPU-only inference binary (per the no-CPU-fallback alpha
+#   contract — see #1262 + tests/no_cpu_fallback_contract.rs). The guard is
+#   correct, but it makes the obvious developer command fail:
+#
+#     cd workers/continuum-core && cargo test tick_db_handle --lib
+#       → fails in the llama crate before the test runs
+#
+#   Fresh installs and agents repeatedly hit this. The fix is a wrapper that
+#   reuses the same `scripts/shared/cargo-features.sh` detector that build
+#   scripts and the precommit hook already source, so `cargo test` Just
+#   Works on every platform.
+#
+# Usage (from src/ — i.e. wherever scripts/ lives):
+#
+#   ./scripts/cargo-test.sh tick_db_handle --lib
+#   ./scripts/cargo-test.sh --test no_cpu_fallback_contract
+#   ./scripts/cargo-test.sh --lib -- --test-threads=1
+#
+# All arguments after the script name pass through to `cargo test`. The
+# wrapper appends the platform feature flags via $CARGO_GPU_FEATURES.
+#
+# Environment overrides (advanced):
+#   CARGO_TEST_RUST_PACKAGE  — workspace package to test (default: continuum-core)
+#   CARGO_TEST_NO_FEATURES=1 — skip the auto-feature append (CI-only debug;
+#                              the macOS llama guard will fail without it)
+#
+# Related (#1257): same pattern as `scripts/git-prepush.sh` Phase 3 cargo
+# test, hoisted from precommit-internal to a developer-facing entry point.

+    # OR the browser isn't connected/responsive, chat-roundtrip hangs
+    # or fails on IPC.
+    #
+    # TWO probes are required because they cover different layers:
+    #
+    # (1) `./jtag ping` — verifies the jtag-client TS surface is alive.
+    #     This is the historical probe but is INSUFFICIENT on its own:
+    #     `jtag ping` runs through PingServerCommand which collects
+    #     server info + optionally pings browser, but NEVER touches the
+    #     Rust continuum-core IPC socket. Returns OK even when core is
+    #     down. (Bug surfaced 2026-05-16 — see codex's airc broadcast
+    #     and claude-tab-1's second-source confirmation that same day.)
+    #
+    # (2) Continuum-core Unix socket probe — verifies the Rust server
+    #     is actually accepting IPC connections. This is what
+    #     chat-roundtrip needs; without it, the gate runs a test that
+    #     can only fail. Two-stage: socket file exists (-S) AND nc
+    #     accepts a 1s connection. A stale socket file from a crashed
+    #     core stays on disk but won't accept, hence both checks.
