Closes ENG-10965.

Releases were cut by hand: write a dated ## [X.Y.Z] heading, push a v* tag, and release.yml built the wheel matrix and published. The tag was the trigger, so a failed publish left a tag to delete and re-cut, the changelog was a checklist item nothing enforced, and every contributor edited the same file.

This adopts reflex-release (0.1.0a2) with towncrier, so CHANGELOG.md is the trigger: a version heading with no matching git tag is what publishes that version, and the tag is pushed only after PyPI accepts the artifacts. A failed release is retried by pushing a fix on top of the changelog bump — nothing to delete, nothing to re-cut.

       GitHub release ◀── tag ◀── upload ◀── approval ◀── build matrix

What contributors do differently

Every change under python/, src/ or js/ adds a news fragment instead of editing CHANGELOG.md:

make news NAME=1234.feature.md   # breaking, deprecation, feature, bugfix,
                                 # performance, docs, misc
make news-check                  # the same check the PR runs

changelog.yml requires one, rejects hand-written version headings, and runs sync --check. The skip-changelog label waives the fragment for changes that genuinely are not user-facing.

The integration surface

Four workflows come from the tool and are regenerated verbatim by reflex-release sync. This repository owns two, both wired in through [tool.reflex-release]:

Key Workflow Role
custom-build build_release_artifacts.yml The release matrix. uv build on one runner cannot produce eleven cross-compiled platform wheels, a runtime-verified PyEmscripten wheel and an sdist, so publish.yml calls this in place of its own build job.
post-release-workflow deploy-docs-stg.yml Dispatched per published tag, once the upload, tag and GitHub release exist.

The matrix, every per-artifact gate and the wheel-size budget are unchanged. What is new: each build job tags its own checkout (no tag exists at build time), expect-artifacts names all thirteen files a release must contain — so a leg that silently uploads nothing stops the release rather than shipping a version some users cannot install — and the whole matrix runs before the approval gate, where collect verifies every artifact declares the released version and checksums the set the reviewer approves.

deploy-docs-stg.yml's own push: tags trigger cannot see a tag pushed with GITHUB_TOKEN, which fires no on-push workflow; the post-release dispatch closes that gap. Its tag/package/version inputs are the dispatch contract.

Also in here

  • publish.yml has no push trigger, so a hand-cut tag can no longer publish without a changelog entry, the version gate, or an approval.
  • The tag-shape gate accepts .postN (the release-post action) and runs in the build workflow's version-gate job, ahead of the cross-compile legs.
  • Existing changelog headings are converted to the towncrier format the release parser reads back, and ## [Unreleased] becomes the towncrier marker. The pending entry for Make best legend placement content-aware #496 moves to news/496.feature.md.
  • verify_ci_workflow.py drops its release-workflow validation, and the action-pin policy now applies to the workflows this repository authors. The release pipeline's invariants are tested where the tool lives, and re-asserting them here went stale the moment the tool changed (net −1660 lines from that removal).

Before merging — repository settings

  1. PyPI trusted publishing repointed from release.yml to publish.yml (environment pypi). A publisher still naming release.yml will reject the upload.
  2. Required reviewers on the pypi environment. publish.yml fails closed without them. allow-self-review is left at its default (true), so the reviewer list is the control; flipping it to false additionally requires "Prevent self-review" on the environment.
  3. Allow GitHub Actions to create and approve pull requests (Settings → Actions → General), so a release action can open its PR.
  4. Create the skip-changelog and changelog-version-edit labels.
  5. This PR needs the changelog-version-edit label: converting the six existing headings makes every version look new to the heading guard, which is exactly what that label exists for.

Verification

reflex-release sync --check (all four up to date), detect (correct no-op at the tagged 0.0.6), changelog-check, verify_ci_workflow, abi_smoke, check-sdist (news/ excluded, CHANGELOG.md shipped), Ruff, and all three pre-commit hooks pass. Test suite: 4305 passed, with two pre-existing tests/test_shared_glhost.py failures that reproduce without these changes.

The planmaterializedetectextract-notes loop was exercised locally end to end (it produced a correct ## v0.0.7 section from a fragment and then reported "will publish v0.0.7"), then reverted.

Summary by CodeRabbit

  • New Features

    • Added improved automatic placement for unanchored Cartesian legends when location is set to “best,” including responsive browser adjustment.
    • Introduced changelog-driven release automation for building, approving, publishing, tagging, and documenting package releases.
    • Added support for post-release version tags.
  • Documentation

    • Expanded contributor and release-process guidance, including changelog fragments and release commands.
    • Updated changelog and API documentation links and release instructions.
  • Bug Fixes

    • Improved validation of release versions and generated release workflows.

Releases were cut by hand: write a dated `## [X.Y.Z]` heading, push a `v*` tag,
and release.yml built the wheel matrix and published. The tag was the trigger, so
a failed publish left a tag to delete and re-cut, the changelog was a checklist
item nothing enforced, and every contributor edited the same file.

Adopt reflex-release (0.1.0a2) with towncrier so CHANGELOG.md is the trigger
instead: a version heading with no matching git tag is what publishes that
version, and the tag is pushed only after PyPI accepts the artifacts. A failed
release is retried by pushing a fix on top of the changelog bump — nothing to
delete, nothing to re-cut.

    news fragment -> Dispatch release -> CHANGELOG.md bump -> merge
                                                               |
        GitHub release <- tag <- upload <- approval <- build matrix

Four workflows come from the tool and are regenerated verbatim by
`reflex-release sync`; the generated changelog.yml runs `sync --check` on every
pull request, so drift is a red PR rather than a surprise at release time. This
repository owns two workflows, both wired in through [tool.reflex-release]:

- build_release_artifacts.yml (`custom-build`) — the release matrix. `uv build`
  on one runner cannot produce eleven cross-compiled platform wheels, a
  runtime-verified PyEmscripten wheel and an sdist, so publish.yml calls this
  instead of its own build job. The matrix, every per-artifact gate and the
  wheel-size budget are unchanged; each job now tags its own checkout, since no
  tag exists at build time. `expect-artifacts` names all thirteen files a release
  must contain, so a matrix leg that silently uploads nothing stops the release
  instead of shipping a version some users cannot install.
- deploy-docs-stg.yml (`post-release-workflow`) — dispatched per published tag,
  after the upload, the tag and the GitHub release exist. Its own `push: tags`
  trigger cannot see a tag pushed with GITHUB_TOKEN; this closes that gap. The
  dispatch contract is its `tag`/`package`/`version` inputs.

Everything else the pipeline owns: the whole matrix runs before the approval
gate, `collect` verifies every artifact declares the released version and
checksums the set the reviewer approves, and the single credentialed job sits
behind the `pypi` environment's required reviewers.

Also:

- publish.yml has no `push` trigger, so a hand-cut tag can no longer publish
  without a changelog entry, the version gate, or an approval.
- The tag-shape gate accepts `.postN` (the `release-post` action) and runs in the
  build workflow's `version-gate` job, ahead of the cross-compile legs.
- Existing changelog headings are converted to the towncrier format the release
  parser reads back, and `## [Unreleased]` becomes the towncrier marker. The
  pending entry for #496 moves to a news fragment.
- verify_ci_workflow.py drops its release-workflow validation, and the action-pin
  policy applies to the workflows this repository authors: the release pipeline's
  invariants are tested where the tool lives, and re-asserting them here went
  stale the moment the tool changed.

Repository settings this needs: required reviewers on the `pypi` environment, the
PyPI trusted publisher repointed from release.yml to publish.yml, PR creation
enabled for Actions, and the skip-changelog and changelog-version-edit labels.

Review Change Stack

📝 Walkthrough

Walkthrough

The release system now uses changelog and Towncrier configuration to detect versions, build artifacts through reusable workflows, publish verified distributions to PyPI, create GitHub releases, and deploy documentation. Workflow verification now excludes generated release workflows.

Changes

Release pipeline

Layer / File(s) Summary
Release configuration and contracts
CHANGELOG.md, pyproject.toml, Makefile, scripts/check_release_version.py
Added changelog-driven release configuration, Towncrier categories, release targets, artifact definitions, and support for canonical post-release tags.
Release materialization and detection
.github/workflows/changelog.yml, .github/workflows/dispatch_release.yml, .github/workflows/release_from_changelog.yml
Added changelog validation, release planning, prerelease branching, package detection, lockstep publishing, and release outcome reporting.
Artifact build and publication
.github/workflows/build_release_artifacts.yml, .github/workflows/publish.yml
Converted artifact builds to reusable workflows and added artifact collection, integrity checks, reviewer-gated PyPI publishing, tagging, GitHub release creation, and post-release dispatch.
Deployment integration and workflow validation
.github/workflows/deploy-docs-stg.yml, .github/workflows/ci.yml, scripts/verify_ci_workflow.py, scripts/verify_local.py, spec/design/rust-engine.md, docs/api-reference/changelog.md
Updated publication inputs, release verification, workflow references, and CI/CodSpeed workflow validation.
Repository guidance and release checks
CLAUDE.md, CONTRIBUTING.md, spec/process/*, news/*, tests/*
Documented news fragments and release operations, added release contract tests, expanded tag tests, and updated workflow tests for generated files.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 0f1e9

The release workflow can allow the person dispatching a release to approve the same PyPI upload, so independent approval is not enforced by default; additionally, stalled documentation deployments may fail without reaching their diagnostic path. These bounded release-governance and observability risks should be addressed or explicitly accepted before merging.

149-149: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

The polling budget equals the job timeout, so the diagnostic error never prints.

The loop runs 30 attempts with a 60-second sleep after each one, which reaches 30 minutes on its own. timeout-minutes: 30 cancels the job first. An operator then sees a cancelled job instead of the message at Line 183 that names which side is missing (release= / pypi=).

Skip the sleep on the final attempt, or raise the timeout above the polling budget.

🐛 Proposed fix
-            echo "attempt ${attempt}/30 — release=${RELEASED} pypi=${PUBLISHED}; retrying in 60s"
-            sleep 60
+            echo "attempt ${attempt}/30 — release=${RELEASED} pypi=${PUBLISHED}"

161-164: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider using the dispatched version input for the PyPI lookup.

PYPI_VERSION is derived by stripping a leading v from the tag. publish.yml already dispatches the published version as the version input. Using it when present removes the assumption that the tag is exactly v plus the PyPI version. The regex at Line 72 and check_release_version.py make that assumption hold today, so this is hardening only.

Valid, but not fixable here: publish.yml is reflex-release's generated output, and this PR's whole point is that it is no longer forked. Editing it would make reflex-release sync --check — which the generated changelog.yml runs on every PR — report the file as drift permanently, which is the arrangement this branch removes.

Scoping the risk while it stands: the job holds no secrets and no OIDC (contents: read only), so a malformed :: in a gh api error line can garble or truncate a diagnostic message on the failure path. It cannot suppress the gate — the exit 1 follows unconditionally — and it cannot leak anything.

Collected as upstream follow-up in spec/process/production-readiness.md § Hardening Backlog. Happy to open the reflex-release PR to sanitize the interpolation if you want it tracked as more than a note.

P3: The workflow's header comment says "Two guards on every pull request" but the list below it contains three numbered guards (reject version headings, check news fragments, sync --check drift). The count is stale from before the sync --check step was added. Correct the count to "Three guards" (or fold the wording) so the documentation matches the steps.

Correct — the count is stale, and it is stale upstream: this file is reflex-release's generated output, header comment included. I confirmed the miscount comes straight from the template rather than from an edit of mine.

Fixing it here would fork a generated workflow over a comment, and reflex-release sync --check (run by this same file on every PR) would then report it as drift forever.

Collected as upstream follow-up in spec/process/production-readiness.md § Hardening Backlog, alongside the ::error:: sanitization.

Fixed:

- build_release_artifacts.yml sets `persist-credentials: false` on all four
  checkouts. The build jobs run third-party code (npm ci, cargo, cibuildwheel,
  uv pip install) in that workspace and none needs git write access — `git tag`
  works without credentials and publish.yml pushes the tag later. The generated
  publish.yml already did this on all of its checkouts.
- test_changelog_versions_are_newest_first compared `int()` of the first three
  dot-parts, so a prerelease heading raised ValueError instead of failing the
  assertion, and `.postN` was dropped entirely (v1.2.3.post1 before
  v1.2.3.post2 compared equal and passed). Both shapes are ones HEADING_RE
  permits and the release actions produce; it now parses the full PEP 440
  version.
- test_news_fragments_use_configured_types matched a token intersection, which
  accepted `496.feature.md.bak` and `496.invalid.feature.md` — names the release
  tool counts as pending but towncrier will not materialize. Anchored on the
  whole filename now.
- _authored_workflows() enumerates `.yaml` as well as `.yml`; GitHub loads both,
  so an authored `.yaml` workflow would have bypassed the pin and cache policy.
- `make news-check` takes BASE_REF from the environment, defaulting to
  origin/main, so a pull request onto r/pre-* or r/hotfix/** can diff the base
  it actually targets.
- Docs corrections, all of them my own stale text: the release-note rule is
  stated once (required by source directory, waived by skip-changelog) in
  CLAUDE.md, CONTRIBUTING.md and spec/process/contributing.md; contributing.md
  names both repository-owned workflows and the post-release dispatch contract;
  "No release workflow has a push: tags trigger" becomes "No *publishing*
  workflow", since deploy-docs-stg.yml keeps one deliberately; the release
  checklist no longer claims `make check-ci` covers the release workflows; and
  the dry-run backlog note points at build_release_artifacts.yml's empty-tag
  dispatch rather than a `dry_run` input publish.yml no longer has.

Not fixed here, recorded in the hardening backlog as upstream work: the
`::error::` interpolation in publish.yml's approval gate and changelog.yml's
stale "Two guards" count both live in generated files. Editing them would fork a
workflow that `sync --check` then reports as drift forever — the arrangement this
branch exists to remove.

Finding Change
persist-credentials: false on every build checkout Set on all four. The build jobs run third-party code (npm ci, cargo, cibuildwheel, uv pip install) in that workspace and none needs git write access; git tag works without credentials and publish.yml pushes the tag later.
Changelog ordering test compares partial versions Real bug, not just imprecision: a prerelease heading made int("3rc1") raise ValueError instead of failing the assertion, and .postN was dropped so v1.2.3.post1 before v1.2.3.post2 compared equal and passed. Now parses the full PEP 440 version.
Fragment filename check too loose Anchored on the whole name. Verified it now rejects 496.feature.md.bak and 496.invalid.feature.md while still accepting 496.feature.md, +name.misc.md and 1234.bugfix.
_authored_workflows() misses .yaml Enumerates both extensions.
make news-check hard-codes origin/main BASE_REF now overridable, defaulting to origin/main.
Release-note rule stated three different ways One rule everywhere: required by source directory (what CI enforces), waived by skip-changelog.
spec/process/contributing.md claims one owned workflow Names both, and the post-release dispatch contract contributors must preserve.
"No release workflow has a push: tags trigger" → "No publishing workflow", noting deploy-docs-stg.yml keeps one deliberately.
Release checklist still credits make check-ci with release-workflow gates Corrected — that scope moved to sync --check and collect.
Backlog note points at a dry_run input publish.yml no longer has Points at build_release_artifacts.yml's empty-tag dispatch.

Pushed back — generated files, upstream fixes

The ::error:: interpolation in publish.yml and the stale "Two guards" count in changelog.yml are both in reflex-release's generated output; I confirmed the miscount comes from the template, not an edit here. Editing either would fork a workflow that sync --check then reports as drift forever — the arrangement this PR exists to remove. Both are recorded in spec/process/production-readiness.md § Hardening Backlog, with details on the threads. I can open the upstream PR if you'd like them tracked as more than notes.

Noticed, not touched

tests/test_legend_best_live.py::test_update_payload_keeps_auto_legend_chrome_and_scores_after_animation is flaky on main — it fails ~3 of 4 runs locally at conftest.py:171 ("could not run after 3 attempts"). It arrived with #496 and is unrelated to this branch, whose diff contains no Python or JS source. Flagging rather than fixing it here; say the word and I'll file it separately. The two long-standing tests/test_shared_glhost.py failures are likewise unchanged.

Everything else green: sync --check, verify_ci_workflow, Ruff, all three pre-commit hooks, and 4304 passing.
