## Checklist Assessment

### Completeness
- [x] **FR-1 Auto Mode in TUI** — `_run_auto_in_tui` implements the full CEO → pipeline loop with iteration headers, StatusBar updates, stop event, concurrent guard, budget/time caps, and persona parsing. All 7 sub-requirements addressed.
- [x] **FR-2 CEO Profile Rotation** — 8 differentiated profiles in `ceo_profiles.py` with meaningful `perspective` fields. Random selection with exclude-last-used. `--persona` flag parsed. Custom profiles from config wired through with sanitization.
- [x] **FR-3 Run Log Persistence** — `TranscriptLogWriter` instantiated in `_launch_tui`, passed to `AssistantApp`, wired into every message type in the queue consumer. Secret redaction, ANSI stripping, `0o600` permissions, log rotation all implemented.
- [x] **FR-4 Transcript Export** — `Ctrl+S` binding exports plain text with `0o600` permissions, shows notice. Added to HintBar.
- [x] **FR-5 Auto-Scroll Fix** — Binary `_programmatic_scroll` guard in `on_scroll_y`. Clean, correct.
- [x] All tasks from prior rounds marked complete
- [x] No TODO/placeholder code

### Quality
- [x] All 96 tests pass
- [x] Code follows existing project conventions (frozen dataclasses, janus queue pattern, `TextualUI` adapter)
- [x] No unnecessary dependencies added
- [x] No unrelated changes included

### Safety
- [x] No secrets in committed code
- [x] Budget/time caps enforced at three checkpoints (pre-CEO, post-CEO, post-pipeline)
- [x] `.colonyos/logs/` added to gitignore via `init.py`
- [x] Log files use `0o600` permissions
- [x] `auto_approve` guard preserved
- [x] Secret redaction applied before log writes

## Detailed Analysis (Karpathy Perspective)

### What's Excellent

**1. The prompt engineering is right.** The 8 CEO profiles are not cosmetic name swaps — they encode genuinely different strategic heuristics. "First-Principles Engineering CEO" will propose different features than "Velocity-Focused Startup CEO" because the `perspective` field shapes the CEO agent's proposal strategy at the system prompt level. This is the correct way to use persona rotation: vary the decision-making prior, not just the greeting.

**2. The architecture treats the model loop as a program.** `_run_auto_in_tui` is essentially a for-loop with three budget gates, a stop event check, error handling per phase, and persona rotation between iterations. This is the right level of structure around an autonomous loop — you're treating each iteration as a transaction with clear entry/exit conditions, not just blindly calling the API in a while True.

**3. The auto-scroll fix is the highest-value change and it's exactly right.** Binary guard flag, no threshold heuristics, no debouncing. The `_programmatic_scroll` flag cleanly separates "the code scrolled" from "the user scrolled." Simple, correct, impossible to get wrong.

**4. Log writer design is clean.** Secret redaction before disk, ANSI stripping, `0o600`, rotation with configurable cap. The queue consumer dispatches to the log writer for every message type — no gaps in coverage.

### Minor Observations (Non-Blocking)

**1. Token parsing is hand-rolled.** `_run_auto_in_tui` parses `--loop`, `--max-budget`, `--max-hours`, `--persona` with a manual for-loop over tokens. This works but is brittle — adding a new flag means editing the loop. For v1 this is fine; if you add more flags, consider `argparse` or even just a small `_parse_auto_args()` helper that returns a typed dataclass. The test suite (`TestAutoInTuiBudgetParsing`) duplicates the parsing logic to test it, which is a test smell — the parsing should be extracted to a testable function.

**2. No least-recently-used profile selection.** The PRD's open question #1 (strategic vs random) is resolved as "random with exclude-last." Over 5+ iterations this can still repeat profiles. Not a blocker — pure random with no-repeat-consecutive is a fine v1 behavior.

**3. The `_run_auto_in_tui` closure captures a lot of state.** It references `app_instance`, `current_adapter`, `config`, `repo_root`, `run_ceo`, `run_orchestrator`, `update_directions_after_ceo`, and several message types. This works because it's defined inside `_launch_tui`, but it's approaching the complexity threshold where extracting it to a class (e.g., `AutoLoopRunner`) would improve testability. The test for budget parsing had to duplicate the logic rather than test the actual function — a sign the coupling is getting tight.

**4. Queue is unbounded.** PRD open question #4 notes this. During a long auto loop, the janus queue could accumulate messages faster than the async consumer drains them. In practice, the consumer is fast (just widget updates), so this is unlikely to matter, but a `maxsize=1000` would be a cheap safety net.

### Round 2 Findings — All Resolved

| Round 2 Finding | Status |
|----------------|--------|
| Budget/time caps not parsed in TUI auto path | **Fixed** — parsed from tokens with config fallback, checked at 3 points |
| `TranscriptLogWriter` never instantiated | **Fixed** — instantiated in `_launch_tui`, wired into consumer |
| Custom CEO profiles from config ignored | **Fixed** — `config.ceo_profiles` passed to `get_ceo_profile()` |
| Two-tier Ctrl+C broken (`self.exit()` on first press) | **Fixed** — first press sets stop event only, second raises `SystemExit` |
| `.colonyos/logs/` not gitignored | **Fixed** — added to `entries_needed` in `init.py` |
| Transcript export default permissions | **Fixed** — `os.open()` with `0o600` |
| `--persona` flag not parsed | **Fixed** — parsed from tokens, passed to `get_ceo_profile(name=...)` |
| No concurrent auto loop guard | **Fixed** — `_auto_loop_active` checked before starting |
| LogWriter cleanup on unmount | **Fixed** — `on_unmount` calls `log_writer.close()` |

VERDICT: approve

FINDINGS:
- [src/colonyos/cli.py]: Token parsing in `_run_auto_in_tui` is hand-rolled and duplicated in tests — consider extracting to a testable `_parse_auto_args()` function (non-blocking)
- [src/colonyos/cli.py]: `_run_auto_in_tui` closure captures extensive state from `_launch_tui` — approaching extraction threshold (non-blocking)
- [src/colonyos/ceo_profiles.py]: Profile selection is random with no-repeat-consecutive, not least-recently-used — fine for v1, revisit if users report repetition in long loops (non-blocking)
- [src/colonyos/tui/app.py]: Janus queue is unbounded — add `maxsize` if long auto loops cause memory pressure (non-blocking)

SYNTHESIS:
All five functional requirements are fully implemented and tested. The three critical findings from round 2 (budget caps, log writer wiring, Ctrl+C semantics) are resolved correctly. The implementation makes sound architectural decisions: the auto loop is structured as a transaction-per-iteration with budget gates, the CEO profiles encode genuine strategic diversity in the prompt, and the auto-scroll fix is the simplest correct solution. 96 tests pass. The remaining observations (hand-rolled parsing, closure complexity, unbounded queue) are technical debt items for future cleanup, not blockers. This is ready to merge.
