Description

Each semantic review run (#19621) leaves two long permanent comments on the PR timeline: the trigger command (~6KB rendered prompt plus pinned revisions) and the CodeRabbit reply. With the 2-hourly scan re-checking PRs as head or target moves, an active PR accumulates several pairs (e.g. #19545 collected five identical trigger comments within ~29 hours). The durable information reviewers need is small: the current state, the revisions it applies to, and a link to the evidence.

This PR adds a tidy job that runs after publish on reply events, only for PRs that have a semantic review request (gated by a new active output of publish):

• Sticky summary comment: one comment per PR, identified by a hidden semantic-review-sticky marker and edited in place. It shows the latest state plus a per-request history table (request time, head/target, verdict, links to the request and reply comments). The latest row is derived from the same reviewState logic as the commit status, so it follows reply edit/deletion revocations instead of falling back to an older PASS.
• Minimize processed pairs: request/reply pairs with a recorded verdict, and requests superseded by a newer one, are minimized via GraphQL minimizeComment (classifier OUTDATED). They stay expandable and link-addressable, so the commit status deep links keep working. The active request stays visible while waiting for its reply.

Design notes:

• The publish job keeps its least-privilege scopes: the existing test invariant (no issues: write, no service PAT in publish) is preserved and extended. The new tidy job holds issues: write + pull-requests: write with read-only status/check access, so the status/check writer and the comment writer are never the same job. Both jobs only run trusted default-branch code, and the sticky body embeds only validated fields (UUID-checked request IDs, regex-checked SHAs, numeric comment IDs, enum verdicts), never raw reply text.
• Rejected alternative: running the cleanup from the 2-hourly request path only. That keeps comment writes off comment-triggered jobs entirely, but delays the summary/minimization by up to two hours and the discover gating cannot detect sticky-only drift.
• Sticky edits and minimization are performed with GITHUB_TOKEN, so they trigger no further workflow runs. The sticky comment contains no live reviewer mention, so no notification is generated by upserts.
• Minimization is best-effort: a failure logs a warning, never blocks the sticky summary or the status path, and self-heals on the next reply event.
• Known limitation (by design): the sticky comment and minimization only advance on CodeRabbit reply events. After the scan posts a new request, the sticky shows the previous state until the reply arrives; the commit status remains the verdict of record, as the sticky comment itself states.
• One point to validate on the first live reply event: that GITHUB_TOKEN with these scopes can minimize (and, after a revoked verdict, unminimize) another user's comment. If it cannot, the fallback is the service PAT, which this PR deliberately keeps out of comment-triggered jobs.

Test Coverage

node --test .github/scripts/semantic_review*.test.js (102 tests, all passing; runs in CI via semantic-review-tests.yml on these paths). New tests cover:

• sticky created once, edited in place, idempotent when unchanged, never pings the reviewer;
• resolved and superseded pairs minimized exactly once; the active waiting request stays visible;
• sticky latest state follows a revoked verdict instead of an older PASS;
• a revoked verdict restores the minimized active request to visible, exactly once, with the same best-effort failure handling;
• history rows follow the newest reply (a correction is shown, not the obsolete reply) and respect the recorded source, so a verdict revoked before supersession is not resurrected; all bound replies of processed requests are minimized;
• minimization failure warns, does not block the sticky summary, and heals on the next run;
• no-op on PRs without a semantic review request and on untrusted events;
• updated workflow invariants: publish still has no comment writes or secrets; tidy has no status/check writes or secrets and is gated on publish's active output.

Dev Engineer Review

• .github/scripts/semantic_review.js adds stickyBody and tidy. The sticky comment shows the latest state and request/reply history. tidy uses reviewState for the active verdict, minimizes completed or superseded comments, and restores an active request when its verdict is revoked. GraphQL minimization or restoration failures warn without blocking the sticky summary.
• .github/workflows/semantic-review.yml adds a tidy job after publish. It runs when publication reports an active request. The job has comment-write permissions and read-only status/check permissions; publish retains status/check writes without comment-write permissions.
• .github/semantic-review.md documents the reply-event timing. The sticky summary and comment visibility can lag a new request until a reply event. The commit status remains the verdict of record.
• No current review findings were supplied. Review severity counts are unavailable.

QA Engineer Review

No test changes.

.github/scripts/semantic_review.test.js changed, but no files under tests/ changed. Its added or modified tests cover sticky-comment creation and editing, minimized completed and superseded comments, revoked verdicts and request restoration, GraphQL failures and retries, untrusted events, and workflow permission invariants. The PR description reports 99 passing tests; this result was not independently verified. Test-list registration is not established and is not applicable to the stated tests/ CI or manual-QA list locations. Coverage verdict: sufficient for the described behavior.

Per-File QA Perspective

• .github/scripts/semantic_review.js: Verify that the sticky comment reflects reviewState, links each request and reply, and updates in place. Verify that completed or superseded comments are minimized, revoked active requests are restored, and GraphQL failures do not block the summary update.
• .github/scripts/semantic_review.test.js: Covers sticky-summary changes, minimization and restoration, failure recovery, trusted-event handling, and workflow permissions. This file is outside tests/ and the specified test-list directories.
• .github/semantic-review.md: Verify that documentation matches reply-event timing, verdict revocation behavior, and best-effort minimization and restoration.
• .github/workflows/semantic-review.yml: Verify that tidy runs after publish only when publication reports an active request. Confirm the shared PR concurrency group and separation of comment-write from status/check-write permissions.

Walkthrough

The semantic review workflow maintains a sticky per-PR summary of request and verdict states. When publication reports an active request, a separate tidy job updates the summary and attempts to minimize completed or superseded comments.

Changes

Semantic review tidy

Layer / File(s)	Summary
Sticky summary and comment minimization .github/scripts/semantic_review.js, .github/scripts/semantic_review.test.js	The script resolves recorded reply sources and verdicts, formats request history, and creates or updates a marked summary. It attempts to minimize processed comments and restores the active request comment when its verdict is revoked. Tests cover summary updates, verdict states, cleanup failures, restoration, and no-op cases.
Workflow invocation and permissions .github/workflows/semantic-review.yml, .github/semantic-review.md, .github/scripts/semantic_review.test.js	The publish job exposes whether a request is active. A separate tidy job runs when it is active, shares the per-PR concurrency queue, and has issue and pull-request write permissions. Documentation and workflow tests cover the job conditions and permissions.

Local verification of the tidy GraphQL operations

The tidy job's GraphQL calls can't execute pre-merge (the workflow only runs default-branch code), and the unit tests mock the client, so they prove the logic but not that the query strings match the live schema. To cover that, I verified the exact strings against the real API:

• Exact-string capture: drove tidy() with a stub client that records each graphql() call, so the tested strings are byte-for-byte what the code sends. The capture scenario also exercised both paths (superseded request minimized, revoked-verdict active request restored).
• Schema validation, side-effect-free: the nodes ... on Minimizable query executed against a real comment and returned isMinimized; both mutations, sent with a well-formed but nonexistent node id, failed only with NOT_FOUND (node resolution), not a validation error. That confirms the mutation names, input shapes (subjectId, classifier: OUTDATED), and payload selections.
• Live round-trip on a real IssueComment (scratch PR on my fork, since closed): minimizeComment returned isMinimized: true, the state query read it back as true, then unminimizeComment returned false, read back as false.

API responses

minimize:    {"data":{"minimizeComment":{"minimizedComment":{"isMinimized":true}}}}
state query: {"data":{"nodes":[{"id":"IC_...","isMinimized":true}]}}
unminimize:  {"data":{"unminimizeComment":{"unminimizedComment":{"isMinimized":false}}}}
state query: {"data":{"nodes":[{"id":"IC_...","isMinimized":false}]}}
nonexistent-id mutations (schema check, both):
  {"errors":[{"type":"NOT_FOUND","message":"Could not resolve to a node with the global id of ..."}]}

Still open, as the description notes: whether GITHUB_TOKEN in the tidy job can minimize/unminimize comments authored by another user. These runs used my PAT on my own comment, so that permission question remains the post-merge check on the first live reply event, with the service PAT as fallback.
