# Review by Linus Torvalds (Round 2)

## Review Complete

Here's my assessment as Linus Torvalds:

**VERDICT: approve**

**Key Findings:**

1. **[router.py:334]** — Minor docstring bug: claims model default is "haiku" but the actual parameter default is "sonnet"
2. **[router.py:246-249]** — Duplicated artifact extraction pattern between `route_query()` and `answer_question()` — should be a helper
3. **[slack.py:844-855]** — Real functional gap: Slack Q&A path doesn't forward `qa_model`/`qa_budget` from config to `answer_question()`, so Slack always uses defaults while CLI respects config

**What's good:**
- All 236 tests pass
- No TODOs, no secrets, no unrelated changes
- Data structures are right: frozen dataclass, simple enum, sensible config defaults
- Security sandboxing is correct: zero tools for classification, read-only for Q&A
- Fail-open on low confidence and parse errors — correct behavior
- Properly reuses existing `run_phase_sync()` infrastructure
- Slack backward compatibility preserved via legacy fallback path
- Comprehensive test coverage (1138 lines) covering edge cases, parse failures, and integration

None of the findings are blocking. The code does the obvious thing at every decision point. Ship it.
