Summary

Elasticsearch community-readiness audit identified 3 P0 blockers, 12 P1 issues, and 4 P2 items. This PR fixes all P0s, most P1s, and the key P2 items, then verifies with quality gates (890 backend + 261 frontend tests, ruff/mypy clean).

P0 fixes (blockers)

  • Bulk API errors silently swallowed — insert_chunks() now batches at 500 docs with 60s timeout and raises BulkIndexError with details on failure
  • storage_mode.sh rejected sqlite for ES pairing — default run-state changed to sqlite (ADR-008); validation updated to accept sqlite
  • Sample PDF gitignored — .gitignore updated to allow input_data/pdfs/sample.pdf; minimal test PDF added

P1 fixes

  • stores.tsv env var drift: ELASTICSEARCH_URL → ELASTICSEARCH_LOCAL_URL
  • client.py: HTTP 401/403/429/503 wrapped in typed errors (ElasticsearchAuthError, ElasticsearchRateLimitError, ElasticsearchServiceUnavailableError)
  • client.py: mask_url() strips credentials from logged URLs
  • client.py: _api_error_status() type-guards meta.status with isinstance(int) — prevents silent comparison failures
  • client.py: raise_if_unreachable() catch-all for unmapped HTTP codes (500, 502, 504) — previously swallowed by callers
  • retriever.py: BM25 score docstring corrected (unbounded, not cross-store comparable)
  • All 11 ES config files: fixed prerequisites (--elasticsearch-local), removed Atlas-specific labels
  • Redis: same sqlite default fix applied to _pair_redis_run_state

P2 fixes

  • num_candidates capped at 10,000 (ES hard limit)
  • Bulk batching at 500 docs with 60s timeout (was unbatched with 10s)

ES error handling hardening

  • _api_error_status(): type guard on meta.status — elasticsearch-py could return status as string, silently breaking all HTTP code comparisons
  • raise_if_unreachable(): catch-all for unmapped HTTP status codes (500, 502, etc.) — previously fell through and were swallowed
  • health_check(): logs exception before returning False (was silently discarding error context)

ES partial-write cleanup + reliability

  • insert_chunks(): partial-write cleanup on BulkIndexError (delete partial docs before raising)
  • Boot ping validates ES reachability at startup (non-fatal warning)

Docker image refactoring

  • server.Dockerfile rewritten as 7-stage named multi-stage build: base-builder → core-deps / elasticsearch-deps / redis-deps → runtime-base → server / server-elasticsearch / server-redis
  • docker-compose.yml: build.target: ${SERVER_BUILD_TARGET:-server} replaces EXTRAS build arg
  • start-services.sh + scripts/lib/compose.sh: export SERVER_BUILD_TARGET for VDB modes
  • Source-code changes skip all deps stages (cached); deps changes rebuild only the matching layer

Dependency security upgrades (7 CVEs fixed)

Docs sync

  • README hero line: lists all four vector stores + sqlite default
  • QUICKSTART: formal Path E (Elasticsearch) and Path F (Redis) sections with prerequisites, commands, error recovery; ToC and stack table updated with ES/Redis rows; Next Steps links added
  • elasticsearch-setup.md: Linux prerequisites section (vm.max_map_count), Docker memory note (3 GB), corrected bulk timeout (60s bulk / 10s query), Known Limitations section (6 items)
  • configuration.md: "defaults to MongoDB" → "defaults to SQLite (ADR-008)" for ES mode; added --redis-local to start flags
  • redis-setup.md: sqlite default throughout
  • architecture.md: C4 diagram + deploy table updated for sqlite as default run-state for ES/Redis
  • CLAUDE.md: backend table updated

fix(scripts): guard resolve_ports exit code for bash 3.2 set-e compat
8a2181c 
On macOS bash 3.2 (system default), the last executed statement in
resolve_ports was [[ false ]] && echo — returning exit 1. With set -e
active this silently aborted the script after docker_cleanup, before
docker compose up was ever reached.

Adding return 0 as the explicit last line makes the function's exit code
unconditional and independent of whether any port-bump announcement fired.

fix(elasticsearch): audit remediation — sqlite default, bulk errors, …
408807f 
…num_candidates cap

Addresses P0/P1 findings from the 2026-10-08 community-readiness audit:

- _pair_elasticsearch_run_state: default STORAGE_BACKEND sqlite (ADR-008);
  sqlite needs no extra container, unblocking --elasticsearch-local without MongoDB
- stores.tsv: fix required_env ELASTICSEARCH_URL -> ELASTICSEARCH_LOCAL_URL
- client.py: add ElasticsearchAuthError / RateLimitError / ServiceUnavailableError;
  mask_url() strips credentials before logging; _api_error_status() extracts HTTP status
- elasticsearch_vector_store.py: batch bulk inserts at 500 docs; inspect bulk
  response errors with _raise_on_bulk_errors() instead of swallowing errors:true
- retriever.py: cap num_candidates at 10 000 to respect ES cluster limit;
  clarify BM25 scores are unbounded and not cross-store comparable
- test: update test_given_elasticsearch_local_when_storage_backend_unset to
  expect sqlite/atlas=0 rather than mongodb/atlas=1

fix(redis): sqlite default run-state for _pair_redis_run_state (ADR-008)
a1c8725 
All vector-only stores (elasticsearch, redis) now consistently default
to sqlite for run state — no extra service required for either VDB path.

- _pair_redis_run_state: STORAGE_BACKEND default mongodb -> sqlite
- configs/redis/*.yaml: update run-state default comment to sqlite (ADR-008)
- docs/user-guide/redis-setup.md: replace postgres-local default claim with
  sqlite (ADR-008); fix env-var table and Switching Backends section
- CLAUDE.md: add --redis-local inline comment; update Local Redis table row
- test: add test_given_redis_local_when_storage_backend_unset_then_run_state_is_sqlite

refactor(docker): base+derived image pattern for VDB server images
f1f734c 
Replace the single-stage ARG EXTRAS build-arg mechanism with named
multi-stage targets. base-builder and runtime-base are the universal
layers; core-deps / elasticsearch-deps / redis-deps each install the
right extras; server / server-elasticsearch / server-redis are the
selectable final targets.

docker-compose.yml uses build.target: ${SERVER_BUILD_TARGET:-server}
instead of the EXTRAS build arg. start-services.sh and compose.sh
export SERVER_BUILD_TARGET=server-{elasticsearch,redis} for VDB modes.

Source-code changes skip the deps stages (cached); deps changes only
rebuild the matching layer and its derived final stage.

…lite default

README hero line now lists all four vector stores instead of only MongoDB
and Postgres. QUICKSTART Path E/F comments corrected from "default
mongodb-local" to sqlite (ADR-008). Configuration guide questions-file
example updated to match actual configs/questions.example.json schema
(personas[].id/questions, not top-level array with persona_id/queries).

fix(elasticsearch): partial-write cleanup, boot ping, and known-limit…
6c60015 
…ations doc

F-C3: insert_chunks now deletes partially-indexed chunks by run_id when a
bulk batch fails mid-way, so a retry starts clean without duplicates.

F-Boot: boot-time ES connectivity warning via resolve_adapter() — warns
when the vector store is Elasticsearch but the cluster is unreachable,
rather than silently failing on first sweep submit.

F-C1/R1/R2: elasticsearch-setup.md Known Limitations — ES 8.x compat note,
sparse score non-comparability, 100-term aggregation cap, refresh:wait_for
performance note, bulk timeout guidance, and contract-test gap.

test(docker): update Dockerfile test for base+derived stage pattern
1ead732 
The f1f734c refactor replaced the EXTRAS="" build arg with dedicated
elasticsearch-deps and redis-deps stages. The test was asserting the
old single-arg pattern; update it to verify the new invariant: core-deps
has no VDB extras, each VDB gets its own named deps stage.

fix(ci): remove --cov-fail-under=95 from pre-push that always checked…
7324096 
… full backend

[tool.coverage.run] source = ["server", "cli"] causes coverage.py to measure
all of server/ + cli/ regardless of --cov=<4 modules>. The --cov-fail-under=95
therefore checked full-backend coverage (75.26%) against 95%, which always fails.

check_backend_coverage_floors.py on line 84 already enforces the correct
per-metric floors (72/59/72) from pyproject.toml on the same JSON output;
the --cov-fail-under flag was redundant and broken by the source override.

fix(elasticsearch): harden error handling — type guard, catch-all, he…
b655622 
…alth_check log

_api_error_status() now type-guards meta.status with isinstance(int) to
prevent silent comparison failures if elasticsearch-py returns status as
a string. raise_if_unreachable() catches unmapped HTTP codes (500, 502,
504) instead of letting them fall through. health_check() logs the
exception before returning False so failures aren't invisible.

… — 7 CVEs

pymongo 4.18.2+ (CVE-2026-88029/96747/96748/96749), fsspec 2026.6.0+
(CVE-2026-104851), multidict 6.9.1+ (CVE-2026-104874), langgraph-sdk
0.4.4+ (CVE-2026-104873). Vitest upgraded to 5.x (path traversal
GHSA-82fw-gwwq-j7x9). npm audit scoped to --omit=dev (braces DoS in
tailwind 3.x devDep is pre-existing on main, fix requires tw 4.x
migration). Removed deprecated pymongo[srv] extra (dnspython is now a
hard dependency in 4.18+).

fix(ci): add --omit=dev to npm audit in CI/nightly workflows
061e872 
braces DoS advisory (GHSA-vfj7-8cjw-p6xm) affects tailwindcss 3.x
(devDependency only). Local scripts already scoped to production deps;
CI and nightly workflows were missing the flag.
