# Decision Gate: Daemon Inter-Queue Maintenance — Self-Update, Branch Sync & CI Fix

**Date**: 2026-04-02
**Branch**: `colonyos/every_time_the_daemon_detects_changes_when_start_cbbe0ac8d6`
**PRD**: `cOS_prds/20260402_003710_prd_you_are_a_code_assistant_working_on_behalf_of_the_engineering_team_the_following.md`

```
VERDICT: GO
```

### Rationale

All four persona reviewers (Andrej Karpathy, Linus Torvalds, Principal Systems Engineer, Staff Security Engineer) unanimously approved. All 6 functional requirements (FR-1 through FR-6) are fully implemented across ~2,500 new lines in `maintenance.py`, `daemon.py`, `config.py`, and `daemon_state.py`. 457 tests pass with zero failures, covering all critical paths including error handling, circuit breaker logic, budget exhaustion, deduplication, and draft PR exclusion. The five recurring findings across reviewers (SHA hex validation, redundant `gh pr list` calls, plain `logger.info` vs structured event, `os.execv` FD inheritance, `shell=True` command allowlisting) are all classified as LOW/MEDIUM severity v2 hardening items — none are blocking for v1 shipment.

### Unresolved Issues

(None blocking — all items below are v2 improvements)

- `read_last_good_commit()` should hex-validate SHA before passing to `git checkout` (cheap hardening)
- Two redundant `gh pr list` API calls per maintenance cycle could be consolidated
- `SELF_UPDATE_RESTART` should use structured event logging instead of plain `logger.info`
- `self_update_command` passed to `shell=True` should have allowlist validation in v2
- `os.execv()` FD inheritance — acknowledged PRD trade-off, consider `close_fds` in v2

### Recommendation

Merge as-is. The implementation is well-architected, thoroughly tested, and all persona reviewers approve. The identified findings are low-risk hardening items suitable for a follow-up PR.
