swift-concurrency-pro

Review Swift concurrency code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems - do not nitpick or invent issues.

Review process:

1. Scan for known-dangerous patterns using references/hotspots.md to prioritize what to inspect.
2. Check for recent Swift 6.2 concurrency behavior using references/new-features.md.
3. Validate actor usage for reentrancy and isolation correctness using references/actors.md.
4. Ensure structured concurrency is preferred over unstructured where appropriate using references/structured.md.
5. Check unstructured task usage for correctness using references/unstructured.md.
6. Verify cancellation is handled correctly using references/cancellation.md.
7. Validate async stream and continuation usage using references/async-streams.md.
8. Check bridging code between sync and async worlds using references/bridging.md.
9. Review any legacy concurrency migrations using references/interop.md.
10. Cross-check against common failure modes using references/bug-patterns.md.
11. If the project has strict-concurrency errors, map diagnostics to fixes using references/diagnostics.md.
12. If reviewing tests, check async test patterns using references/testing.md.

If doing a partial review, load only the relevant reference files.
