# Review by Principal Systems Engineer (Google/Stripe caliber) (Round 2)

## Review Complete

**VERDICT: approve**

Here's my assessment as Principal Systems Engineer:

### All 18 PRD requirements are implemented and tested

The implementation delivers a complete `colonyos queue` command with `add`, `start`, `status`, and `clear` subcommands. All functional requirements (FR-1 through FR-18) are met, including:

- **Durable queue state** in `.colonyos/queue.json` with atomic writes
- **Crash recovery** — RUNNING items reset to PENDING on restart, KeyboardInterrupt properly reverts in-progress items
- **Budget/time caps** via `--max-cost` and `--max-hours` with graceful halting
- **Fault isolation** — failed/rejected items don't block subsequent items
- **Issue re-fetch** at execution time for freshest content
- **Rich summary tables** and `status` integration

### Test results: 914 tests passing (49 queue-specific)

### Minor findings (non-blocking):

1. **Verdict regex duplication** — `_NOGO_VERDICT_RE` in cli.py duplicates logic from `orchestrator.py:_extract_verdict()`. Maintenance landmine if the format changes.
2. **Config not reloaded between items** — Unlike the `auto` loop, queue doesn't reload config between items. Low impact but inconsistent.
3. **`queue_id` required key** — `from_dict()` will `KeyError` on corrupted files instead of graceful degradation.
4. **Budget cap None safety** — Works today because `BudgetConfig` defaults are non-None, but the assumption is implicit.
