# Decision Gate

Verdict: **GO**

```
VERDICT: GO
```

### Rationale
All four personas unanimously approve with zero critical or high-severity findings. The implementation correctly addresses all 10 functional requirements from the PRD — daily thread creation/rotation, structured overnight summaries (zero LLM cost), critical alert elevation via `critical=True` on all 5 callers, restart recovery via DaemonState persistence, backward-compatible `per_item` mode, and solid config validation. Test coverage is comprehensive with 491+ tests passing (55 new) across config, state, lifecycle, routing, summary, and integration scenarios. The PR also improves existing code by consolidating token handling from 2 paths to 1.

### Unresolved Issues
- None blocking merge.

### Recommendation
Merge as-is. Three minor advisory items for follow-up:
- Add a comment explaining the double `_ensure_daily_thread()` call (idempotent short-circuit)
- Document that `_create_daily_summary` filters by `added_at` date (intentional V1 choice)
- Consider a follow-up PR for mrkdwn sanitization of user-controlled fields (pre-existing pattern, not introduced here)
