### Persona Verdict Tally

| Persona | Round 4 Verdict |
|---|---|
| Andrej Karpathy | ✅ **APPROVE** |
| Linus Torvalds | ✅ **APPROVE** |
| Principal Systems Engineer | ✅ **APPROVE** |
| Staff Security Engineer | ✅ **APPROVE** |

**Result: 4/4 approve — unanimous.**

### Severity Assessment

**CRITICAL findings:** None.

**HIGH findings:** None.

**MEDIUM findings (non-blocking):**
- Heuristic `"change"` pattern in router can over-match at 0.9 confidence for ambiguous requests — mitigated by model fallback and review phase never being skipped.
- `--no-tui` flag inconsistently available; CLI flags silently dropped when TUI activates.
- `run_sweep()` conflates analysis and execution success in a single `PhaseResult`.
- `target_path` not validated before use in sweep prompt.
- Hardcoded `"tests/"` prefix in preflight recovery scope check.

**LOW findings:**
- Dual routing taxonomies (conceptual overhead, not a bug).
- `_tui_available()` import check not cached.
- `run()` signature bloat (15+ params).
- Latent idle-animation desync if glyph/phrase lists diverge.
- `parse_sweep_findings()` silently returns empty on format mismatch.

VERDICT: GO
```

### Rationale
All four reviewers unanimously approve. The implementation covers three PRDs (~9,300 lines, 73 files) with zero CRITICAL or HIGH findings, all 1,933 tests passing, no secrets in code, and no placeholder implementations. The architecture is sound — janus queue bridge for TUI concurrency, read-only tools for sweep analysis, defense-in-depth sanitization, and review phase never skipped regardless of routing classification. The MEDIUM findings (heuristic over-matching, CLI flag inconsistency, sweep target_path validation) are real but non-blocking: they have mitigations in place and are safe to address in a follow-up iteration.

### Unresolved Issues
- Heuristic routing patterns (especially `"change"`) need tightening to avoid misrouting complex requests to direct agent
- `--no-tui` flag should be added consistently across all commands; incompatible CLI flags should block TUI activation
- `run_sweep()` should separate analysis success from execution success in its return value
- `target_path` should be validated (exists, within repo) before injection into sweep prompt
- Hardcoded `"tests/"` prefix should be configurable or use project convention detection
- `parse_sweep_findings()` should log a warning when non-empty output yields zero parsed findings
- `run()` signature should be refactored into a `RunOptions` dataclass before it grows further

### Recommendation
**Merge as-is.** The unresolved issues are all MEDIUM/LOW severity with existing mitigations. Open a follow-up issue tracking the items above for the next iteration, prioritizing the heuristic routing tightening and CLI flag consistency.
