Not linked; this is a task-requested workflow maintenance fix.

Description

The PR review-state workflow now recognizes reviews from both the CodeRabbit GitHub App account (coderabbitai[bot]) and the legacy coderabbitai account. Both identities share the existing CodeRabbit review state and remain excluded from human-maintainer approval checks, preserving the requirement for a separate maintainer review.

It also reconciles every open PR when main advances, so conflicts introduced by base-branch changes promptly replace stale review-state labels with has-conflicts. Before applying awaiting-maintainer, the workflow refreshes GitHub's mergeability fields: false/dirty is treated as conflicted, while null/unknown fails closed until GitHub finishes calculating.

State transitions add the desired label before removing the previous one. If that add fails, the workflow reports failure but preserves the existing state label instead of letting outer cleanup leave the PR unlabeled.

The workflow retains pull-requests: write, which is required for its PR label mutations. Other token scopes remain limited to metadata access, contents remains disabled, and the workflow never checks out or executes PR code.

Focused harness coverage verifies both CodeRabbit account forms and the conflict states observed on PR #1311, including dirty-at-sweep, unknown-to-dirty, and persistently unknown responses.

Test Procedure

Run:

pnpm --dir src exec vitest run services/__tests__/pr-review-state-workflow.test.ts
pnpm --dir src exec eslint --max-warnings=0 services/__tests__/pr-review-state-workflow.test.ts
pnpm exec prettier --check src/services/__tests__/pr-review-state-workflow.test.ts
git diff --check

The workflow suite passes all 104 cases. Commit and push hooks also ran the repository-wide lint and type-check tasks successfully.

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Pull request review-state labels are now refreshed when changes are pushed to the main branch.
    • Pull requests with merge conflicts are labeled accordingly before awaiting maintainer review.
    • Review status remains pending while mergeability is still being calculated, preventing premature labeling.
    • Reviews from supported CodeRabbit account formats are recognized consistently for accurate status tracking.
    • Existing review-state labels are preserved when a new label cannot be applied, preventing loss of status information.

Walkthrough

The workflow now reconciles open pull requests after pushes to main, preserves state labels when desired-label assignment fails, recognizes both CodeRabbit login forms, and rechecks mergeability before applying maintainer-review labels. Tests cover conflicts, pending mergeability, push events, and alternate CodeRabbit identities.

Changes

Review state reconciliation

Layer / File(s) Summary
Main push and mergeability reconciliation
.github/workflows/label-pr-review-state.yml, src/services/__tests__/pr-review-state-workflow.test.ts
Pushes to main now reconcile open pull requests. The workflow re-fetches mergeability before assigning awaiting-maintainer, applies has-conflicts for dirty conflicts, and uses mergeability-pending while mergeability is unknown. Desired-label failures preserve existing state labels. Tests cover sequential responses and push-event behavior.
CodeRabbit identity normalization
.github/workflows/label-pr-review-state.yml, src/services/__tests__/pr-review-state-workflow.test.ts
The workflow maps coderabbitai[bot] and coderabbitai to one identity for review deduplication and maintainer-review filtering. Tests cover alternate casing, user types, and permission lookup failures.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to ddbe1

The workflow can still ignore comments from one supported CodeRabbit account and can assign an incorrect review-state label when a PR head changes during reconciliation. These behavior gaps should be fixed before merging.

Full details: Regression Evidence

Explanation

The PR adds shared CodeRabbit identity keys for latest-review deduplication (reviewerKey in .github/workflows/label-pr-review-state.yml:633-639), but the focused tests only exercise one CodeRabbit review at a time (pr-review-state-workflow.test.ts:1034-1051). The tests cover recognition of CodeRabbitAI[bot] and coderabbitai, including maintainer filtering, but they do not cover both identities in one review history. Therefore they do not verify that approval, change-request, comment, or dismissal state is resolved across the shared identity. The push sweep, mergeability-pending, conflict, and label-add failure paths have focused tests. No UI change requires a Playwright snapshot.

Resolution

Add focused harness tests with both coderabbitai[bot] and coderabbitai reviews in chronological order. Assert that the later meaningful review controls the single CodeRabbit state and that the alias is not treated as a human maintainer. Include at least a cross-alias CHANGES_REQUESTED case after approval, plus a dismissal/comment case if those states remain part of the shared latest-review contract.

Fixed in d90c34874. Label transitions now add the desired state before removing the previous state, and desired-label add failures bypass outer state-label cleanup so the prior label remains intact. Added a dirty/conflict regression test that forces has-conflicts addition to fail and verifies awaiting-maintainer is not removed.

Validation: workflow harness 104/104 passed; targeted ESLint and Prettier passed; workspace type checks and repository-wide commit-hook lint passed.

Apply the two-login allowlist at both event gates.

codeRabbitLogins includes coderabbitai, but the job-level condition at Line 46 and the in-script guard at Lines 93-95 still accept only coderabbitai[bot]. A real issue comment from coderabbitai is skipped before the script can reconcile the PR.

The identity tests invoke workflowScript directly, so they do not exercise the job-level if condition. Update both gates to use the same two-login allowlist and add event-filter coverage.

Revalidate the PR head before using refreshed mergeability.

For push and scheduled reconciliation, pr came from pulls.list. This branch refreshes mergeability into latestPrDetail, but later checks and review comparisons still use pr.head.sha, and label mutations still use the original pr snapshot.

If the PR receives a commit between those requests, checks and approvals for the old commit can satisfy the workflow, and the workflow can assign the current PR an incorrect review state. Use the fresh PR object for all subsequent evaluation, or stop when the head SHA changes.
