# Review by Linus Torvalds (Round 3)

## Review Complete

**VERDICT: request-changes**

Here's my assessment as Linus Torvalds:

### What's Right
The architecture is fundamentally sound. The watch→triage→queue→execute→report pipeline is the obvious correct design — QueueState as producer-consumer backing store, triage as a single-turn no-tools haiku call, strict git ref validation. Data model changes are clean and backwards-compatible. All 422 tests pass. Security properties are solid.

### What Needs Fixing

**Critical code quality issues:**
1. **`_queue_executor` is a 150+ line closure** nested inside `watch()`, capturing 10+ variables from the enclosing scope. This is unmaintainable spaghetti — extract it into a `QueueExecutor` class with explicit state.
2. **`slack_client_ref: list[object] = []`** — a mutable list hack to share the Slack client across threads. Use a proper threading primitive.
3. **`original_branch` declared twice** in `orchestrator.py` — dead code on the first declaration, shadowed by the second.
4. **`_make_ui` typed as `object`** — that's giving up on types. Use a proper `Callable`.

**Functional concerns:**
5. **`triage_message()` is synchronous in the Bolt event handler** — if the LLM takes >3 seconds, Slack may retry the event, causing duplicate processing.
6. **`triage_message()` uses `Path(".")` as cwd** instead of `repo_root` — wrong if process cwd differs from repo.
7. **`git checkout` in the `finally` block** doesn't handle a dirty working tree — will silently fail.

**Scope:**
8. **745-line README rewrite** is unrelated to this feature — should be a separate PR.
