# Decision Gate

Verdict: **GO**

---

```
VERDICT: GO
```

### Rationale
All four personas (Andrej Karpathy, Linus Torvalds, Principal Systems Engineer, Staff Security Engineer) unanimously approve. The implementation is a clean, surgical fix that correctly removes `agent_lock` from the stateless triage path, adds bounded retry with proper transient/non-transient error separation, marks failed triages as `triage-error` to prevent Slack redelivery loops, and closes the TOCTOU rate-limit gap by moving `increment_hourly_count` into the `state_lock` critical section. All 8 PRD functional requirements are satisfied. Zero CRITICAL or HIGH findings. The one MEDIUM finding (transient exception tuple may miss HTTP-client-specific exceptions like `httpx.ReadTimeout`) is fail-safe — the message gets marked `triage-error`, not silently dropped.

### Unresolved Issues
(none blocking)

### Recommendation
Merge as-is. Consider a follow-up to inspect `triage_message()`'s actual exception surface and add any HTTP-client-specific timeout types to the transient exception tuple.
