Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughAdds an advisory semantic-conflict review workflow. It creates revision-pinned requests for eligible pull requests, verifies CodeRabbit replies against recorded revisions and source evidence, and publishes non-required GitHub Checks and merged-PR audit comments. It also adds scheduled scans, preview and test workflows, operator documentation, and automated tests. ChangesSemantic review automation

Suggested reviewers: Merge Risk: 🔵 Low · up to This change adds advisory semantic-conflict Checks that never block merges. One open pull request with a FAIL verdict will make the six-hourly scan job show red on every run, which can hide real scan errors from operators. Fixing this is a small change. The PR is otherwise reasonable to merge with this follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A reused FAIL result makes the request job red on every scan.
requestOne calls publish when an exact pair already has a result. For a verified FAIL, publish runs core.setFailed(message) at .github/scripts/coderabbit_semantic_review_result.js Line 211. That call marks the request/scan job as failed.
A scheduled scan revisits every open PR, plus merged PRs from the last 24 hours. So one open PR with a verified FAIL turns every six-hour scan red. Any pull_request_target event that reuses the pair also turns the request job red.
This behavior has two consequences:
- It contradicts the operator guide: "A successful request job only means orchestration succeeded."
- It hides real per-PR scan errors from the
core.setFailed('Some PRs could not be scanned; ...')path at Line 213, because the job is already red for an unrelated reason.
The FAIL verdict should change only the Check conclusion and the result-publishing job. Suppress the job failure when orchestration calls publish.
🐛 Proposed fix
- if (result) await publish({github, core, context: {...context, eventName: 'issue_comment',
- payload: {issue: {number}}}});
+ if (result) await publish({github, core, failJob: false, context: {...context,
+ eventName: 'issue_comment', payload: {issue: {number}}}});In .github/scripts/coderabbit_semantic_review_result.js:
async function publish({github, context, core, failJob = true}) {
// ...
} else if (result.verdict === 'FAIL' && failJob) core.setFailed(message);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Replaced by #19621.
Description
Problem
PRs can merge cleanly while breaking behavior changed on the target branch.
Solution
Add advisory CodeRabbit semantic checks for non-draft PRs targeting
mainorrelease/**:Commands use
trtllm-agent; privileged jobs never execute PR code. See the operator guide for the complete policy.Supersedes #19268 with the final implementation in one commit.
Test Coverage
Validation
e4b0ddc6385738fb74689b50b4a2e24641134ae5, all 59 Node tests passed locally and in GitHub; local pre-commit hooks passed. Policy tests use an in-memory GitHub API.PR Checklist
Dev Engineer Review
The change adds advisory CodeRabbit semantic checks for PRs targeting
mainorrelease/**. It covers event and scheduled requests, request limits and retries, result verification, and post-merge audits. The native CodeRabbit check stays disabled during ordinary reviews. FAIL can mark the check red, but the check is non-required and does not gate merging.The operator guide documents deployment risks. The service-account command flow, privileged check publication, and merged/release PR behavior still need a deployment pilot. The preview tests do not verify production triggers, permissions, command acceptance, or post-merge behavior. No current review findings were provided.
QA Engineer Review
No test changes.
The new Node test suite is under
.github/scripts/, nottests/. The PR objective reports that all 59 Node tests and local pre-commit hooks passed at the stated revision. These results do not establish production workflow behavior or general detection accuracy. No integration test-list changes are reported.Per-File QA Perspective
