## Review Summary

I've completed my review of the `colonyos pr-review` implementation. Here's my assessment:

**VERDICT: approve**

**FINDINGS:**
- [src/colonyos/cli.py]: Circuit breaker cooldown logic duplicated in watch loop (lines ~3730 and ~3770) - could be extracted to helper
- [src/colonyos/cli.py]: `pr_review()` function is ~420 lines; long but linear, acceptable for now
- [src/colonyos/pr_review.py]: Well-structured module following existing patterns
- [src/colonyos/orchestrator.py]: Minimal, correct extension to support PR review context

**SYNTHESIS:**
This implementation is correct and follows the established patterns in the codebase. The data structures are simple, the security model is sound, and all PRD requirements are met. The code reuses existing infrastructure (run_thread_fix, triage_message, QueueItem) rather than reinventing it. Tests are comprehensive with 39 new tests passing (1291 total tests pass). The only minor issue is some duplicated logic in the CLI watch loop, but it's not worth blocking over. The atomic file writes for state persistence are done correctly, the untrusted input sanitization is applied at every entry point with defense-in-depth, and the safety guards (budget cap, circuit breaker, max fix rounds, HEAD SHA verification) are all implemented and tested. Ship it.
