A new PHP branch used to stall at the implementation run's readiness record, which no Protected controls exemption covered, so it needed a manual approval. This adds an exemption for that record, bound to its validated merge commit, the in-progress implementation run and the base commit, and lets record PRs from runs that started on an ancestor of main merge, so a finalize rerun after main moves still files its record. The notifier now ignores issues and comments that github-actions[bot] didn't write, so a copied marker in this public repo can't hijack or silence the owner alert.

Summary by CodeRabbit

  • Automation
    • Release event records can now be filed while a workflow is running, provided it started from the current main branch or an ancestor.
    • Qualifying readiness records can be approved after the main branch advances, subject to commit history and policy checks.
  • Bug Fixes
    • Automated recovery now trusts only issues and comments authored by GitHub Actions, so unrelated records no longer affect recovery.
    • Invalid readiness records are rejected, and records that do not qualify for the exemption still require owner review.

Protected controls now admits an implementation run's php_bin_ready record
bound to its validated merge commit, and accepts record PRs from runs that
started on an ancestor of main. The notifier only trusts issues and comments
written by github-actions[bot].

📝 Walkthrough

Walkthrough

Protected-controls admission now validates readiness records and accepts qualifying trusted runs from the PR base’s commit history. Notification discovery filters issue markers and comments by workflow authorship.

Changes

Protected event admission

Layer / File(s) Summary
Readiness record validation
autorelease/_state.py, autorelease/control.py, tests/test_autorelease.py
Shared event-history validation checks completed records. The readiness-record validator checks the record shape, lifecycle transition, merge evidence, and digest fields. Tests cover valid records and deviations.
Protected-controls admission
.github/workflows/protected-controls.yml, AUTORELEASE.md, tests/test_autorelease.py
Completed-event and readiness-record admission accepts qualifying trusted runs started at the PR base or an ancestor. Tests cover accepted and rejected cases. The documentation describes admission requirements and finalize behavior.

Notification authorship filtering

Layer / File(s) Summary
Filter notification records by author
scripts/notify-autorelease, tests/test_autorelease.py
Issue discovery and fingerprint recovery use only workflow-authored records. Tests cover bot and non-bot authors.

The readiness exemption now requires the record's policy digests to match the base tree, an uncomparable start commit is rejected with a reason, and a non-string action key fails validation instead of raising.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Handle reruns after the validated merge reaches main.

When exact_base_sha is A and main has advanced to descendant B, verify_merge compares the admitted phpBinHead A with the current origin/main B and rejects the rerun before the readiness record step runs. The workflow does not regenerate the record for B. A readiness record already created on B still names A, so protected-controls.yml rejects it because merged_commit != base.

Add a rerun path that validates the already-merged commit against the current base before creating the readiness record. Do not replace phpBinCommit with B without revalidating the implementation and readiness contract.

Thanks, this is a real gap, and it's older than this PR: if the implementation run merges the lifecycle patch and then fails before its readiness record lands, a rerun is rejected because main has moved, and the next watcher run stops at needs_human. This PR only changes how Protected controls admits the record, so I'm keeping it focused and fixing the recovery path in a follow-up: when the lifecycle edits are already on main, the classifier will resume the new_branch or branch_eol action and the implementation run will revalidate and build from main, then file the readiness record for that exact commit. That keeps phpBinCommit bound to a validated commit, as you suggested.
