## Review Complete

**VERDICT: approve**

**FINDINGS:**
- [src/colonyos/tui/widgets/status_bar.py]: `_last_rendered` field is dead code — stored but never read. Remove it.
- [src/colonyos/tui/widgets/transcript.py:109-118]: Plain-text fallback strips indentation from code output. Minor UX papercut for v1.
- [src/colonyos/tui/widgets/composer.py]: `_on_key` intercept reaches into Textual internals — fragile but pragmatic for v1.
- [src/colonyos/tui/app.py:173]: `type: ignore` comment on lambda should be a proper type annotation fix, not a silencing comment.

**SYNTHESIS:**
This is a clean, minimal implementation that does exactly what the PRD asks for and nothing more. The data structures are right: frozen dataclasses for the queue messages, a janus queue for the thread boundary, RichLog for the transcript instead of widget-per-event insanity. The adapter correctly implements all 8 PhaseUI methods and sanitizes at every boundary. The file structure is sensible — one file per widget, one adapter, one app shell. All 1842 tests pass (1695 existing + 147 new) with zero regressions. The sanitizer improvements are a genuine security fix that would be worth merging independently. There are minor papercuts — dead `_last_rendered` field, plain-text indentation stripping, a `type: ignore` that should be a proper fix — but none of these are blocking issues. The code is simple, obvious, and correct. Ship it.
