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:

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

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