  • Require an explicit stable tag and a matching mutable draft release.
  • Benchmark the resolved tag commit and verify the uploaded archive's size and SHA-256 digest before publishing the draft.
  • Reuse matching draft assets on publisher retries without overwriting conflicting assets or modifying published releases.
  • Require fresh draft checks when rerunning benchmarks.
  • Document draft creation, workflow dispatch, and failed-run recovery.

Closes #225

Summary by CodeRabbit

  • Release Workflow

    • Benchmark releases now require manual dispatch using a stable version tag and validated draft release.
    • Release commits, artifacts, and asset integrity are verified before publication.
    • Successful workflows publish the validated draft automatically; failures leave releases unpublished.
    • Conflicting, stale, or mismatched release data is rejected, while safe reruns can reuse verified assets.
  • Documentation

    • Updated benchmarking and releasing guidance covers prerequisites, validation, retries, recovery, permissions, and publication safeguards.
  • Tests

    • Expanded coverage for release validation, artifact handling, retries, and publication failure scenarios.

📝 Walkthrough

Walkthrough

The release benchmark workflow now runs for an explicit stable tag and mutable draft release. It benchmarks the validated commit, verifies a run-specific baseline asset, uploads it without clobbering, and publishes the draft only after validation. Documentation and tests cover the new flow and recovery behavior.

Changes

Release benchmark publication

Layer / File(s) Summary
Draft release preflight
.github/workflows/release-benchmarks.yml, .github/actions/prepare-release-benchmarks/action.yml, scripts/tests/test_release_baseline.py, docs/BENCHMARKING.md
Manual dispatch requires a stable tag. Preflight validates the mutable draft release, tag commit, workflow attempt, and tagged workflow definition before benchmarking.
Pinned benchmark artifact
.github/workflows/release-benchmarks.yml, scripts/tests/test_release_baseline.py
Benchmark execution uses the validated commit and produces a run-specific temporary artifact.
Verified draft publication
.github/workflows/release-benchmarks.yml, scripts/tests/test_release_baseline.py
The publisher verifies release identity, tag commit, asset type, digest, and size. It uploads only absent assets and publishes the draft after successful verification.
Release procedure and recovery
docs/BENCHMARKING.md, docs/RELEASING.md
Documentation describes draft creation, publication checks, permissions, retries, asset reuse, and failure recovery.

- Run benchmarks from the release tag and check out the workflow's own commit to keep execution in that tag's cache scope.
- Reject mismatched dispatch refs and tags moved since dispatch.
- Update release instructions to use --ref "$TAG" instead of main.
