## Security Review — Staff Security Engineer, Round 1

**VERDICT: request-changes**

### The Bottom Line

**There is no implementation to review.** The branch `colonyos/colonyos_needs_to_be_fully_autonomous_...` sits at the exact same commit as `main` (`e717237`) with zero commits ahead. The working tree contains 8 unmerged conflict files and a small staged-but-uncommitted partial implementation (just the `QueueItem.priority` field and a `compute_priority()` helper in `models.py`). All 50+ tasks in the task file are marked incomplete.

### What's Missing (Everything Critical)

Every security-critical control described in the PRD is absent:

| Control | Status | Security Impact |
|---|---|---|
| `allowed_control_user_ids` | ❌ Missing | Any Slack user can trigger arbitrary code execution |
| Daily budget cap (`$50/day`) | ❌ Missing | Runaway loop burns entire API budget |
| Circuit breaker | ❌ Missing | Poisoned queue item retries forever |
| Slack kill switch (pause/stop) | ❌ Missing | No human override for autonomous operation |
| PID lock file | ❌ Missing | Multiple daemon instances corrupt shared state |
| Atomic state writes | ❌ Missing | `queue.json` corruption on crash |
| Crash recovery | ❌ Missing | Orphaned RUNNING items never cleaned up |
| systemd hardening | ❌ Missing | No `ProtectSystem`, no `PrivateTmp` |
| `/healthz` endpoint | ❌ Missing | No observability into daemon state |

**Core daemon files don't exist**: `daemon.py`, `daemon_state.py`, `DaemonConfig`, the CLI command, the systemd unit file — none of them.

### What Was Partially Done

- `QueueItem.priority` field added (schema v4) with `compute_priority()` helper — ~10% of FR-3
- Tests for the above in `test_models.py`
- An unrelated `test_instructions.py` file for instruction template quality

### FINDINGS:
- **[branch]**: Zero commits ahead of main — no implementation exists
- **[working tree]**: 8 files in unmerged conflict state — branch is unbuildable
- **[FR-6 daily budget]**: NOT IMPLEMENTED — primary cost-safety control missing
- **[FR-11 kill switch]**: NOT IMPLEMENTED — no human override for autonomous execution
- **[FR-7 circuit breaker]**: NOT IMPLEMENTED — no runaway failure protection
- **[FR-8/FR-9 crash safety]**: NOT IMPLEMENTED — no recovery, no atomic writes

### SYNTHESIS:
This is a system with extreme privilege — `bypassPermissions`, unattended 24/7 execution, access to API tokens and git credentials on a VM. The PRD correctly identifies the safety controls needed (budget caps, circuit breakers, kill switches, allowed user lists, atomic persistence, crash recovery). **None of them have been built.** The branch needs to go back to implementation. When it returns, I'll be scrutinizing: (1) `allowed_control_user_ids` being mandatory and non-empty in daemon mode, (2) daily budget as a hard gate before every pipeline run, (3) atomic writes for all persistent state, (4) systemd unit with `ProtectSystem=strict`, and (5) the kill switch functioning even when the executor thread is blocked.
