- Optimized scripts/review_pull_requests.py to use a single git for-each-ref call with the ahead-behind atom, reducing subprocess calls from O(N) to O(1) and improving execution time from ~0.34s to ~0.09s.
- Optimized scripts/ci_validate_repo.py by using os.walk for faster directory traversal and chunked reading for NUL byte detection.
- Added commit subject to the PR review output.
- Updated Bolt's journal with new learnings.
