## Assessment

The implementation actually exists now. That's a dramatic improvement over round 1. Let me tear into the code.

### What's Good

1. **The scroll fix is correct.** Binary model (`at_bottom = auto-scroll`), `_programmatic_scroll` guard to prevent `scroll_end()` from re-triggering `on_scroll_y`. This is the obvious, simple solution. No over-engineering. Good.

2. **CEO profiles are clean data.** A tuple of frozen `Persona` dataclasses with a simple `get_ceo_profile()` function. No class hierarchy, no registry pattern, no abstraction astronautics. The `exclude` parameter to avoid consecutive duplicates is straightforward. `parse_custom_ceo_profiles()` sanitizes user input. Fine.

3. **Log writer is simple and does one thing.** `TranscriptLogWriter` opens a file descriptor with `0o600`, strips ANSI, redacts secrets, flushes on each write. Rotation is oldest-first glob sort. No async, no buffering complexity, no framework dependency. This is what I like to see.

4. **Test coverage is solid.** 52 new tests across 3 files covering profiles, log writer, and transcript scroll behavior. All 2,104 tests pass clean.

5. **The adapter message types are frozen dataclasses.** `IterationHeaderMsg` and `LoopCompleteMsg` — dead simple, immutable. Correct.

### What's Wrong

6. **`_run_auto_in_tui` only parses `--loop`.** The PRD (FR-1.2) explicitly requires `--max-hours`, `--max-budget`, and `--persona` flag parsing from the composer input. The CLI `auto` command has full budget/time enforcement (lines 1869-1945), but `_run_auto_in_tui` has **zero** budget enforcement, **zero** time cap enforcement, and no `--persona` flag parsing. This is a functional gap — a user could type `auto --loop 100` and burn through their entire budget with no guardrail. The CLI path has this. The TUI path doesn't. This needs to be fixed.

7. **`_auto_loop_active` is set but never checked as a guard.** The PRD (FR-1.7) says `_run_active` must prevent starting a second auto loop while one is running. The code sets `self._auto_loop_active = True/False` but nothing in `on_composer_submitted` or `_handle_tui_command` checks it before starting another auto run. The `_run_active` flag in the worker `_start_run` path provides some protection, but the auto command goes through a different code path (`_run_auto_in_tui` is called directly from the worker callback, not via `_start_run`). A user could potentially trigger overlapping auto loops.

8. **`action_export_transcript` doesn't set `0o600` permissions.** The log writer correctly uses `os.open()` with `0o600` for session logs, but `action_export_transcript` uses `Path.write_text()` which creates files with default permissions (typically `0o644`). This is inconsistent — either both should be restrictive or neither, but the PRD security section says log files should be `0o600`. Transcript exports are log files.

9. **`action_cancel_run` always calls `self.exit()`.** The two-tier cancellation is supposed to be: first Ctrl+C = graceful stop (set stop event, let current iteration finish), second Ctrl+C within 2s = force exit. But the current code calls `self.exit()` on the **first** press too (line 261). This means the "graceful stop" immediately kills the TUI. The whole point of the stop event is to let the loop wind down while the TUI stays alive so the user can see the results.

10. **`_run_auto_in_tui` swallows the `_run_active` lifecycle.** The function sets `_auto_loop_active` but never sets `_run_active = True`. Meanwhile `on_composer_submitted` checks `_run_active` to guard against double-runs. Since `_run_auto_in_tui` runs inside the worker callback that already set `_run_active = True`, this might accidentally work, but it's fragile — the control flow depends on an undocumented assumption about the caller's state.

11. **Log writer (FR-3/FR-7) is never wired into the TUI.** `TranscriptLogWriter` exists in `log_writer.py` and has tests, but **nothing in `cli.py` or `app.py` instantiates it**. The `_consume_queue` loop doesn't write to any log file. The `_launch_tui` function doesn't create a `TranscriptLogWriter`. Task 7.2 says "Instantiate `TranscriptLogWriter` in `_launch_tui` and hook it into the `_consume_queue` loop" — this was not done. The log writer is dead code.

12. **Closure capture bug in the auto loop.** `_ui_factory` captures `adapter2` by reference, but `adapter2` is reassigned each iteration. Since `_ui_factory` is a closure defined inside the loop body, it will always capture the correct `adapter2` for that iteration's scope. Actually — wait, no, Python closures capture by reference to the variable, not the value. But since `adapter2` is a local assigned before `_ui_factory` is defined in the same iteration scope... this is fine in practice because `_ui_factory` is consumed within the same iteration. But it's unnecessarily confusing. A `functools.partial` or passing the adapter directly would be clearer.

### Minor Issues

13. **`get_plain_text()` creates a new `Console` per line.** For a long transcript this is O(n) Console objects. Not a correctness bug, but wasteful. A single Console instance reused across lines would be cleaner.

14. **`_rotate_old_logs` runs at init time.** This means the rotation check happens when the writer is created, not when a new file is about to exceed the limit. If the user creates many files between runs, the first write of the next run deletes the excess. Fine in practice, but slightly surprising.

## Checklist

### Completeness
- [x] FR-1 (auto in TUI): Core loop works, but missing `--max-hours`, `--max-budget`, `--persona` parsing
- [x] FR-2 (CEO profiles): Fully implemented
- [x] FR-3 (log persistence): Writer exists but **not wired** — dead code
- [x] FR-4 (transcript export): Implemented, missing `0o600` permissions
- [x] FR-5 (auto-scroll fix): Fully implemented and correct
- [ ] All tasks marked complete: Yes, but Tasks 7.2/7.3 (log writer integration) are marked done without implementation

### Quality
- [x] All 2,104 tests pass
- [x] Code follows existing project conventions
- [x] No unnecessary dependencies
- [x] No unrelated changes

### Safety
- [ ] `action_export_transcript` uses default file permissions, not `0o600`
- [ ] No budget/time enforcement in TUI auto path
- [x] Secret redaction in log writer
- [x] `sanitize_display_text` on custom CEO profiles

VERDICT: request-changes

FINDINGS:
- [src/colonyos/cli.py:5266-5273]: `_run_auto_in_tui` only parses `--loop`, missing `--max-hours`, `--max-budget`, `--persona` flags required by FR-1.2 and FR-2.4
- [src/colonyos/cli.py:5252-5375]: No budget or time cap enforcement in TUI auto loop — user can burn unlimited budget; CLI path has this at lines 1869-1945
- [src/colonyos/cli.py + src/colonyos/tui/app.py]: `TranscriptLogWriter` is never instantiated — Tasks 7.2/7.3 (log writer integration) are marked complete but not implemented; log writer is dead code
- [src/colonyos/tui/app.py:261]: `action_cancel_run` calls `self.exit()` on first Ctrl+C, defeating the two-tier cancellation design where first press should be graceful stop only
- [src/colonyos/tui/app.py:98]: `_auto_loop_active` is set/cleared but never checked — no guard prevents starting concurrent auto loops
- [src/colonyos/tui/app.py:288]: `action_export_transcript` uses `Path.write_text()` without setting `0o600` permissions, inconsistent with log writer security model

SYNTHESIS:
The bones are good. The data structures are right — frozen dataclasses for messages, a simple tuple of profiles, a straightforward log writer with correct permissions and secret redaction. The scroll fix is the correct, obvious solution. The test coverage is real and passes clean. But the integration layer has significant gaps: the log writer is literally dead code (built and tested but never plugged in), the budget enforcement that exists in the CLI auto path was not ported to the TUI auto path, the two-tier cancellation is broken because `self.exit()` fires on first press, and three PRD-required flags aren't parsed. These are not nitpicks — they're missing functionality that the tasks claim is done. Fix the wiring: plug in the log writer, add budget/time enforcement, parse the remaining flags, make first-Ctrl+C graceful (no exit), and guard against concurrent auto loops. Then this ships.
