## Review: `colonyos/implement_the_latest_prd_tasks_file`

This branch implements three PRDs in one shot: (1) a Textual TUI with transcript/composer/status bar, (2) TUI UX fixes + smart routing with complexity classification, and (3) a `colonyos sweep` command for autonomous codebase quality analysis. That's ~9,200 lines added across 72 files, with 31 commits.

### Completeness

- **TUI (PRD 1 & 2)**: All functional requirements implemented — `colonyos tui` command, `--tui`/`--no-tui` flags, TranscriptView (RichLog-based), Composer with auto-grow, StatusBar with idle animation, TextualUI adapter using janus queue, optional dependency under `[tui]` extra, output sanitization, Ctrl+C cancellation with double-tap force-quit, mid-run user injection, `exclusive=False` on workers. ✅
- **Smart Routing (PRD 2 FR-7)**: `complexity` field added to `RouterResult`, heuristic + LLM mode selection, `skip_planning` fast path in orchestrator, `_write_fast_path_artifacts()` for lightweight PRD/task stubs. ✅
- **Sweep (PRD 3)**: `Phase.SWEEP` enum, `SweepConfig` dataclass, `sweep` CLI command with `--execute`/`--plan-only`/`--max-tasks`/`--verbose`/`--quiet`/`--force`/`--no-tui`, `run_sweep()` orchestration, `sweep.md` instruction template, read-only tool list `["Read", "Glob", "Grep"]`, dry-run report, execute delegation to `run()` with `skip_planning=True`. ✅
- **Preflight Recovery**: Bonus feature — `PREFLIGHT_RECOVERY` phase with secret file detection, scope validation, and recovery commit agent. Not in any PRD but clearly useful for TUI dirty-worktree handling. ✅
- **All 1,927 tests pass.** Zero regressions. ✅
- **No TODO/FIXME/HACK/PLACEHOLDER in shipped code.** ✅
- **No secrets in committed code.** ✅

### Quality Assessment

**What's done right:**

1. **The data structures are clean.** `SweepConfig`, `ModeAgentDecision`, `ModeAgentMode` are simple, frozen where appropriate, with sensible defaults. The `RouterResult.complexity` field addition is non-breaking with a `"large"` default.

2. **The sanitizer hardening is genuinely good.** The expanded ANSI regex catches OSC/DCS sequences, and the `\r` normalization prevents content-overwrite attacks. This is a real security fix.

3. **The preflight recovery scope validation is paranoid in the right way.** Secret file detection, scope-creep detection (`_recovery_scope_extras`), and verification that all blocked files were actually committed — this is defensive programming that will prevent agent misbehavior.

4. **The heuristic mode selector is smart.** Using regex patterns with negative lookahead to avoid false positives like "make sure" or "change my mind" before falling through to the LLM classifier. The fallback chain is correct.

5. **The sweep phase uses read-only tools only** — `["Read", "Glob", "Grep"]`, exactly as specified. The safety gate is architecturally correct.

**What concerns me:**

1. **`router.py` grew from a focused classifier to a 900-line mode-selection + routing + Q&A kitchen sink.** The `ModeAgentMode`/`ModeAgentDecision` system is a parallel classification hierarchy to `RouterCategory`/`RouterResult`. There are now two ways to classify intent (`route_query` vs `choose_tui_mode`), and the caller has to know which to use. This isn't broken, but it's heading toward a tangle.

2. **`_drain_injected_context()` is called at 5 separate points in `_run_pipeline`** (implement, review, fix, decision, deliver). If someone adds a new phase, they'll forget to call it. The injection model should be a single decorator or loop wrapper, not manually wired. But for v1 this works.

3. **The `run_sweep()` return type `tuple[str, PhaseResult]` is asymmetric with the rest of the orchestrator.** `run()` returns `RunLog`. `run_ceo()` returns something else. Now `run_sweep()` returns yet another shape. I'd prefer consistency, but I won't block on it.

4. **The `ceo_persona` type-guard fix** in `config.py` (`isinstance(ceo_persona_raw, dict)`) is a bugfix that silently landed. Good fix, but it's unrelated to the three PRDs — it should be in its own commit.

### Safety

- No secrets or credentials in committed code ✅
- Secret file detection in preflight recovery prevents auto-committing `.env`, private keys, certificates ✅
- All user-injected text goes through `sanitize_untrusted_content()` before reaching agents ✅
- Sweep analysis phase is read-only — no Write/Edit/Bash tools ✅
- Review phase is never skipped regardless of complexity classification ✅
- Error handling present for all agent call failures with sensible fallbacks ✅

VERDICT: approve

FINDINGS:
- [src/colonyos/router.py]: Dual classification hierarchy (RouterCategory/RouterResult + ModeAgentMode/ModeAgentDecision) creates parallel intent-routing systems. Consider unifying in a future pass.
- [src/colonyos/orchestrator.py]: `_drain_injected_context()` is manually wired at 5 call sites in `_run_pipeline`. A missed call site when adding future phases will silently drop user context.
- [src/colonyos/orchestrator.py]: `run_sweep()` returns `tuple[str, PhaseResult]` while `run()` returns `RunLog` — inconsistent orchestrator return types.
- [src/colonyos/config.py]: `ceo_persona` type-guard fix (`isinstance(ceo_persona_raw, dict)`) is an unrelated bugfix that should have been a separate commit.
- [src/colonyos/sanitize.py]: The `\r` normalization and expanded ANSI regex are genuinely good security hardening.

SYNTHESIS:
This is a large branch — three PRDs worth of features in 9,200 lines — but the code is structurally sound. The data structures are the right ones, the tests are comprehensive (1,927 passing), the security boundaries are correct (read-only sweep, sanitized injection, secret detection), and there's no placeholder code. The main architectural concern is the growing dual-classification system in router.py, which will need unification before it becomes a maintenance burden. But for v1 this ships correctly. The code does what the PRDs say it should do, the tests prove it, and nothing is going to blow up in production. Approve.
