Commit: ${commit_ref:-}

Rules:

- Review only the diff below.

- Review the proposed code change as a closeout reviewer.

- Focus on the diff below. If your CLI exposes read-only repository tools, inspect surrounding code and tests to verify findings; never modify files.

- Do not modify files.

- Prioritize correctness bugs, regressions, security issues, and missing tests.

- Ignore speculative edge cases and broad rewrites.

- Report only discrete, actionable issues introduced by this change.

- Prioritize correctness, regressions, security, data loss, performance cliffs, and missing tests that would catch a real bug.

- Do not report pre-existing issues, speculative risks, broad rewrites, style nits, changelog gaps, or findings that depend on unstated assumptions.

- Identify the concrete scenario where the issue appears, and keep the line reference as small as possible.

- A finding should overlap changed code or clearly cite changed code as the cause.

- For each accepted/actionable finding, use exactly this format:
