Review changes
- Establish the intended behavior from the request and repository guidance.
- Inspect the complete relevant diff, including staged, unstaged, and newly added files.
- Trace changed data and control flow into callers and tests.
- Report only actionable findings caused by the change. Rank them by impact and cite exact files and lines.
- Verify suspected bugs against code or a focused reproduction; do not report style preferences as defects.
- If there are no findings, state that directly and name any verification gap that remains.
