## Persona Verdicts

| Persona | Latest Round | Verdict |
|---------|-------------|---------|
| Andrej Karpathy | Round 3 | **APPROVE** |
| Linus Torvalds | Round 2 | **APPROVE** |
| Principal Systems Engineer | Round 1 | **APPROVE** |
| Staff Security Engineer | Round 1 | **APPROVE** |

## Finding Summary

| Severity | Count | Status |
|----------|-------|--------|
| CRITICAL | 0 | — |
| HIGH | 0 | — |
| MEDIUM | 1 | Deferred to v2 (rate-limit warning leak for passive messages) |
| LOW | 2 | Accepted (dead test variable, explicit message_subtype filtering) |

```
VERDICT: GO
```

### Rationale
All four personas unanimously approve with no CRITICAL or HIGH findings. The implementation delivers all 8 functional requirements from the PRD with ~45 lines of production code across 4 files, activating latent infrastructure rather than building new machinery. The critical security invariant — `should_process_message()` as the single untouched access-control chokepoint — is preserved. Test coverage is excellent at ~680 lines of new tests covering dedup races, dual-event delivery, queue-full privacy, and startup warnings.

### Unresolved Issues
- Rate-limit warning at lines 194-204 of `slack_queue.py` posts to channel for passive messages — should be guarded with `if not is_passive` (LOW impact, deferred to v2)
- Post-triage 👀 reaction fires before queue item creation — pre-existing pattern, not a regression (informational)
- No explicit `message_subtype` early-return — downstream guards sufficient (informational)

### Recommendation
Merge as-is. The one substantive finding (rate-limit warning leak for passive messages) is low-impact — rate limiting is rarely hit, and the message goes to a thread. File a follow-up issue to guard the rate-limit `post_message` with `if not is_passive` in v2.
