# Decision Gate

Verdict: **GO**



Now I have all the information needed to make my decision. Let me write the verdict.

---

```
VERDICT: GO
```

### Rationale

All 5 personas **unanimously APPROVE** the implementation. The code changes are well-structured: a new `pr_sync.py` module (320 lines) with worktree-isolated merge execution, proper config extension (`PRSyncConfig` dataclass, opt-in disabled by default), schema migration for `OutcomeStore`, daemon tick integration as concern #7, and comprehensive test coverage (781 lines in `test_pr_sync.py` alone, plus additions to 4 other test files). The implementation faithfully covers all PRD functional requirements (FR-1 through FR-15): detection via cached `mergeStateStatus`, 1-PR-per-tick sequential processing, conflict abort + Slack/PR comment notification, failure escalation after configurable retries, circuit breaker isolation, and write-enabled gating.

The single cross-cutting finding (MEDIUM) — that FR-13's write gate uses `dashboard_write_enabled` config but not the `COLONYOS_WRITE_ENABLED` environment variable — is a fail-closed gap (operators using only the env var get sync silently disabled, not accidentally enabled), which all 5 reviewers agreed is non-blocking and safe to address in a follow-up.

### Unresolved Issues

- **MEDIUM**: FR-13 write gate only checks `dashboard_write_enabled` config, not the `COLONYOS_WRITE_ENABLED` env var — operators relying solely on the env var will have sync silently disabled.
- **LOW**: `_last_pr_sync_time = 0.0` triggers an immediate sync on first daemon startup rather than waiting one full interval.
- **LOW**: Minor inconsistency in conflict file truncation (5 files in Slack, 10 in PR comment).
- **INFO**: `_get_rev` returns the string `"unknown"` on failure rather than raising — benign since the value is only used in log messages.

### Recommendation

**Merge as-is.** The MEDIUM FR-13 env-var gap should be tracked as a fast follow-up ticket (one-line fix to also check `os.environ.get("COLONYOS_WRITE_ENABLED")`). The LOW/INFO items are cosmetic and can be addressed opportunistically.
