# Decision Gate: `colonyos show <run-id>` — Single-Run Inspector

## Persona Verdicts

| Persona | Verdict | Key Findings |
|---|---|---|
| Andrej Karpathy | ✅ APPROVE | Clean architecture, thorough tests (51), no blockers |
| Linus Torvalds | ✅ APPROVE | Solid workmanlike code, minor dup in collapse logic |
| Principal Systems Engineer | ✅ APPROVE | All 9 FRs implemented, 51+7 tests, minor nits only |
| Staff Security Engineer | ✅ APPROVE | Read-only, path traversal mitigated, zero new attack surface |

**Tally: 4/4 APPROVE, 0 REQUEST-CHANGES**

## Finding Severity Summary

| Severity | Count | Description |
|---|---|---|
| CRITICAL | 0 | — |
| HIGH | 0 | — |
| MEDIUM | 1 | `load_single_run` lacks defense-in-depth re-validation (mitigated by caller) |
| LOW | 5 | Duplicated fix/else branches, `str|list` return type, broad substring matching, `all()` on empty list (guarded), `--json` outputs raw data not computed fields |

## Test Results

- **147 tests pass** (test_show.py + test_cli.py) in 0.59s
- **Zero regressions** in full test suite (865 tests per reviewer reports)
- All 9 PRD functional requirements implemented and tested

---

VERDICT: GO

### Rationale
All four personas unanimously approve. There are zero CRITICAL or HIGH findings. The implementation cleanly follows the established `stats.py` data/render separation pattern, covers all 9 PRD functional requirements (FR-1 through FR-9), and includes 51 unit tests plus CLI integration tests with zero regressions. The MEDIUM finding (missing defense-in-depth in `load_single_run`) is mitigated by the existing validation in `resolve_run_id` and is acceptable for v1.

### Unresolved Issues
- (None blocking merge)

### Recommendation
Merge as-is. The branch carries 4 unrelated ci-fix commits which is a merge hygiene concern — consider rebasing or squash-merging to keep the show feature isolated. The minor findings (duplicated fix/else branches, `--json` outputting raw data vs computed fields) are reasonable follow-up improvements but do not block shipping.
