# Decision Gate

Verdict: **NO-GO**

---

```
VERDICT: NO-GO
```

### Rationale
The HEAD SHA capture bug (`cli.py:2676-2679`) directly undermines multi-round fix support — a core feature of this PR. After `run_thread_fix()` returns, the `finally` block has already restored the original branch, so `_get_head_sha()` returns the wrong SHA. This incorrect SHA propagates to the parent `QueueItem`, causing all subsequent fix rounds to falsely fail with "force-push detected." Additionally, `run_thread_fix()`'s `finally` block lacks the stash-before-checkout logic present in `run()`, meaning a mid-edit agent crash leaves the watch process stranded on the wrong branch. 4 of 5 personas approved, but the Principal Systems Engineer (Google/Stripe) correctly identified these two HIGH-severity issues.

### Unresolved Issues
- **HEAD SHA capture after branch restore** (`cli.py:2676-2679`): `_get_head_sha()` called after `finally` restores original branch → wrong SHA propagated → false failures on round 2+. Fix: use `log.preflight.head_sha` instead.
- **Missing stash in `run_thread_fix()` finally block** (`orchestrator.py`): If Implement phase crashes mid-edit, `git checkout` back to original branch fails, leaving repo on fix branch for subsequent queue items. Fix: add stash-before-checkout matching `run()`'s pattern.

### Recommendation
Address the two HIGH findings (~30 minutes of work), re-run the full test suite, and re-submit. The implementation is otherwise production-ready — all 21 PRD requirements are met, test coverage is comprehensive, security posture is strong, and all other findings are non-blocking cleanup items.
