Start with this prompt

Written for this task. Fill in the bracketed parts.

Review this diff.

Focus on correctness first: logic errors, unhandled cases, race conditions,
anything that breaks an existing caller. Then readability. Ignore formatting.

For each issue, tell me the severity and the concrete scenario where it bites.
If the change is fine, say so plainly instead of inventing nitpicks.
