# Decision Gate

Verdict: **GO**

I have enough information to make my decision. Let me summarize the findings:

## Summary of Reviews

| Persona | Verdict | Key Findings |
|---------|---------|--------------|
| **Andrej Karpathy** | ✅ APPROVE | Triage confidence not used (minor); all 17 FRs implemented; excellent security patterns |
| **Linus Torvalds** | ✅ APPROVE | Some duplicated logic in CLI watch loop (minor); correct data structures; comprehensive tests |
| **Principal Systems Engineer** | ✅ APPROVE | No file lock for concurrent instances (LOW); no exponential backoff (LOW); trailing newline (TRIVIAL) |
| **Staff Security Engineer** | ✅ APPROVE | No comment author validation (documented as v2); no rate limiting on API calls; defense-in-depth sanitization is good |

```
VERDICT: GO
```

### Rationale
All four persona reviewers unanimously approved the implementation. All 17 functional requirements from the PRD are implemented and tested. The critical security controls (input sanitization at multiple layers, HEAD SHA verification, budget caps, circuit breaker) are correctly implemented. No CRITICAL or HIGH severity issues were identified — all findings are LOW severity or deferred-to-v2 items that are explicitly documented in the PRD's Non-Goals section.

### Unresolved Issues
- None blocking. The following are LOW/deferred items noted for v2:
  - No file lock preventing concurrent `--watch` instances on the same PR
  - No exponential backoff on persistent network failures in watch loop
  - Triage confidence score captured but not used for decision-making
  - Comment author validation deferred to v2 (explicitly documented in PRD)
  - Trailing blank line at EOF in `pr_review.py:479`

### Recommendation
**Merge as-is.** The implementation meets all PRD requirements, follows existing codebase conventions, has comprehensive test coverage (39 new tests, 1291 total passing), and implements all critical safety guards. The minor issues identified (file locking, exponential backoff, confidence threshold) are reasonable v2 improvements but do not block shipping this feature.
