## Review: Linus Torvalds — Round 3

**VERDICT: approve**

### Completeness

- [x] **FR-1 Auto Mode in TUI** — Full loop works: `auto --loop N --max-budget X --max-hours Y --persona Z` parsed from composer, routed through `_AUTO_COMMAND_SIGNAL`, runs CEO → pipeline per iteration with real-time queue messages. Budget/time caps checked at 3 points (pre-iteration, post-CEO, post-pipeline). Concurrent guard via `_auto_loop_active`. Stop event checked between iterations.
- [x] **FR-2 CEO Profile Rotation** — 8 profiles with genuinely distinct `perspective` fields. Random selection with consecutive-duplicate avoidance. `--persona` pin works. Custom profiles from config wired through with `sanitize_display_text`.
- [x] **FR-3 Run Log Persistence** — `TranscriptLogWriter` instantiated in `_launch_tui`, passed to `AssistantApp`, wired into every message type in `_consume_queue`. `0o600` permissions via `os.open`. Secret redaction. ANSI stripping. Oldest-first rotation. `.colonyos/logs/` gitignored.
- [x] **FR-4 Transcript Export** — Ctrl+S → `get_plain_text()` → `os.open` with `0o600` → notice with path. Added to HintBar.
- [x] **FR-5 Auto-Scroll Fix** — `_AUTO_SCROLL_THRESHOLD` removed. Binary at-bottom check. `_programmatic_scroll` guard on `scroll_end()` calls. `re_enable_auto_scroll()` via End key. This is the correct fix — simple, obvious, no clever tricks.
- [x] All tasks complete, no TODOs or placeholder code.

### Quality

The data structures are right. `IterationHeaderMsg` and `LoopCompleteMsg` are frozen dataclasses — you know exactly what flows through the queue. `CEO_PROFILES` is a tuple of `Persona` — immutable, obvious. The scroll fix is 6 lines of code that does exactly what it says.

Two minor style observations (not blocking):

1. **`_consume_queue` is growing**. The `if lw:` / `lw.write_*` pattern repeats 8 times. This isn't wrong — it's explicit and you can see exactly what gets logged — but if another message type gets added, consider extracting the log-writing dispatch into a method on the writer that takes the message directly.
2. **`get_plain_text()` creates a `Console` per line** (transcript.py:248-252). For a 5000-line transcript that's 5000 Console objects. Fine for on-demand Ctrl+S export, don't use in a hot path.
3. **`cast(Any, adapter)`** appears 3 times. Type-system band-aid — `TextualUI` implements the `PhaseUI` protocol but the type checker can't see it. Acceptable pragmatism, but a `Protocol` class or `register` call would be cleaner long-term.

### Safety

- [x] `auto_approve` guard preserved — auto in TUI requires explicit opt-in
- [x] Budget caps enforced with config fallback (not just CLI flags)
- [x] Log files `0o600`, secrets redacted via `SECRET_PATTERNS`
- [x] `.colonyos/logs/` gitignored
- [x] Custom CEO profiles sanitized via `sanitize_display_text`
- [x] No secrets or credentials in committed code
- [x] Two-tier Ctrl+C: first press graceful (stop event + cancel workers), second press hard exit

### Tests

96 tests pass. Coverage includes:
- CEO profile selection, exclusion, custom profiles, sanitization (14 tests)
- Log writer: permissions, ANSI stripping, secret redaction, rotation, double-close safety (15 tests)
- Auto token parsing: all flags, defaults, invalid values (8 tests)
- TUI app: cancel semantics, export permissions, log writer integration, consumer dispatch (12 tests)
- Scroll behavior: programmatic guard, re-enable (in test_transcript.py)

### Findings

- [src/colonyos/tui/app.py]: `_consume_queue` has 8 repetitions of `if lw: lw.write_*()` — explicit but could be consolidated if more message types are added (minor, not blocking)
- [src/colonyos/tui/widgets/transcript.py]: `get_plain_text()` allocates a Console per line — fine for on-demand export, don't use in hot paths (informational)
- [src/colonyos/cli.py]: `cast(Any, adapter)` used 3 times to bridge TextualUI to PhaseUI — works but a Protocol registration would be cleaner (minor, not blocking)

### Synthesis

This is correct code. Not clever code — correct code. The scroll fix is 6 lines that do exactly the right thing. The data structures are obvious: frozen dataclasses flow through a typed queue, each message type maps to exactly one handler. The auto loop has proper lifecycle management — stop event, budget caps at three checkpoints, concurrent guard, graceful cancellation that doesn't kill the TUI. The log writer does file I/O with restricted permissions and secret redaction. The CEO profiles are honest-to-god meaningful persona definitions, not cosmetic name swaps. Two rounds of review caught real issues (uncapped budget in TUI path, dead log writer, broken Ctrl+C) and all were fixed with clean, minimal patches. 96 tests pass. Ship it.
