## Assessment

The implementation has gone from zero to a solid, working state. All 52 new tests pass (29 unit + 23 widget). Let me assess each functional requirement from the lens of "are we using the model effectively, and is the system reliable?"

### FR-1: Auto Mode in TUI — ✅ Implemented

The `_run_auto_in_tui` function (cli.py:5252) correctly:
- Parses `--loop N` from composer input
- Creates a fresh `TextualUI` adapter per iteration
- Emits `IterationHeaderMsg` / `LoopCompleteMsg` through the janus queue
- Checks `_stop_event` between iterations for graceful cancellation
- Catches `PreflightError` and generic exceptions per-iteration with `continue`

Two-tier Ctrl+C (app.py:240-261) correctly uses `time.monotonic()` with 2s window.

**Concern**: `--max-hours` and `--max-budget` flags are NOT parsed in `_run_auto_in_tui` (lines 5266-5273 only parse `--loop`), even though the PRD's FR-1.2 explicitly requires them and the task file 5.6 says to parse them. The CLI `auto` command (line 1840-1841) has these, but the TUI path doesn't. This means a user typing `auto --loop 5 --max-budget 10` in the TUI will silently ignore the budget cap.

**Concern**: `--persona` flag is not parsed either, despite FR-2.4 and task 5.6 requiring it. Users can't pin a specific CEO profile from the TUI composer.

### FR-2: CEO Profile Rotation — ✅ Well Implemented

`ceo_profiles.py` defines 8 genuinely differentiated personas. The perspective fields encode real strategic preferences, not just cosmetic name changes — this is exactly right. "Ruthlessly eliminate complexity" vs. "What performance bottleneck, if removed, would unlock an entirely new user experience?" will produce meaningfully different CEO proposals when injected into the system prompt.

`get_ceo_profile()` correctly avoids consecutive duplicates via the `exclude` parameter. The fallback when all candidates are excluded is correct.

`parse_custom_ceo_profiles()` sanitizes through `sanitize_display_text` — good prompt injection mitigation.

`_build_ceo_prompt` (orchestrator.py:1514) correctly falls back: passed persona > config persona > default. The `ceo_persona` parameter on `run_ceo` (orchestrator.py:1625) is clean.

**Minor note**: The selection is pure random, not least-recently-used as I recommended in the PRD. For v1 with 8 profiles and typical 3-5 iteration runs, random-with-exclusion is fine. The consecutive-duplicate avoidance covers the worst case.

### FR-3: Log Persistence — ⚠️ Partially Implemented

`TranscriptLogWriter` (log_writer.py) is well-built:
- `0o600` permissions via `os.open` + `os.fdopen` — correct
- Secret redaction via `SECRET_PATTERNS` — correct
- ANSI stripping — correct
- Oldest-first rotation — correct
- `close()` is idempotent — correct

**Critical gap**: The `TranscriptLogWriter` is **never instantiated** in the actual TUI session. I searched `cli.py` and `app.py` for any reference to `TranscriptLogWriter` or `log_writer` — zero results. The class exists, it's tested, but it's not wired in. Task 7.2 says "Instantiate `TranscriptLogWriter` in `_launch_tui` and hook it into the `_consume_queue` loop" and is marked complete, but the code doesn't do this.

This means FR-3 ("Every TUI session must write a plain-text transcript log") is not actually functional.

### FR-4: Transcript Export — ✅ Implemented

`action_export_transcript` (app.py:277-289) correctly:
- Calls `get_plain_text()` to extract content
- Writes to `.colonyos/logs/transcript_{timestamp}.txt`
- Shows a notice with the path

`get_plain_text()` (transcript.py:242-253) uses Rich's `Console(no_color=True)` to strip markup — correct approach.

`Ctrl+S` binding and `HintBar` hint both present.

**Minor**: The exported file is written with default permissions (not `0o600`). The PRD doesn't explicitly require restricted permissions on exports, but for consistency with the log writer's security posture, it should match.

### FR-5: Auto-Scroll Fix — ✅ Well Implemented

The scroll fix is architecturally clean:
- `_programmatic_scroll` guard (transcript.py:47, 53, 64-66) prevents `on_scroll_y` from firing during `scroll_end()`
- Binary scroll detection (transcript.py:59): `self._auto_scroll = self.scroll_y >= max_scroll`
- `re_enable_auto_scroll()` method for End key
- No `_AUTO_SCROLL_THRESHOLD` — correctly removed

The test at line 206-214 verifies the guard works. This is the highest-value fix in the PR and it's done correctly.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/cli.py:5266-5273]: `_run_auto_in_tui` only parses `--loop` but ignores `--max-hours`, `--max-budget`, and `--persona` flags. FR-1.2 and FR-2.4 require these. A user typing `auto --loop 10 --max-budget 5` will burn through budget with no cap enforcement. This is a safety issue for autonomous operation.
- [src/colonyos/cli.py + src/colonyos/tui/app.py]: `TranscriptLogWriter` is fully implemented and tested but never instantiated during a TUI session. FR-3 ("Every TUI session must write a plain-text transcript log") is non-functional. Task 7.2 is marked complete but the wiring code is missing.
- [src/colonyos/tui/app.py:288]: `action_export_transcript` writes files with default permissions, inconsistent with the `0o600` security posture of the log writer. Minor but worth fixing for defense-in-depth.
- [src/colonyos/cli.py:5252-5376]: The `_run_auto_in_tui` function doesn't use config's `ceo_profiles` (custom user profiles). It always calls `get_ceo_profile(exclude=...)` without passing `custom_profiles=config.ceo_profiles`, so user-defined CEO profiles in config.yaml are ignored in the TUI auto path.

SYNTHESIS:
From an AI engineering perspective, the implementation gets the hard parts right: the persona rotation genuinely shapes CEO behavior through meaningful perspective/expertise fields (not just name swaps), the prompt plumbing through `_build_ceo_prompt` correctly prioritizes passed persona over config defaults, and the scroll fix eliminates the most disruptive UX failure mode. The architecture — janus queue, frozen dataclass messages, adapter pattern — is clean and the right level of complexity. However, there are three gaps that matter: (1) budget/time caps not enforced in the TUI auto path is a real safety issue for autonomous operation — you're giving the model an uncapped loop, (2) the log writer is dead code that was presumably part of a larger integration that didn't land, and (3) custom CEO profiles from config aren't plumbed through. None of these are architectural issues — they're straightforward wiring fixes that should take 30 minutes total. Fix those three and this is a clean approve.
