# Review by Andrej Karpathy (Round 2)

VERDICT: approve

FINDINGS:
- [src/colonyos/slack_queue.py]: `is_passive` defaults to `False` in `_triage_and_enqueue` signature — correct defensive default, means existing callers don't break.
- [src/colonyos/slack.py]: `extract_prompt_text` returns `text.strip()` for non-mention messages. The downstream `sanitize_slack_content` handles deeper cleaning. Two-layer sanitization is fine — strip is idempotent.
- [tests/test_slack_queue.py]: The `_mock_triage` side-effect pattern uses `threading.Event` for synchronization — correct approach for testing the async triage worker without flaky sleep-based waits.

SYNTHESIS:
This implementation is exactly what I'd want to see: activating a latent capability with minimal new code, keeping the stochastic boundary (triage LLM) unchanged, and using pure deterministic logic for the new prompt extraction path. The `is_passive` flag is clean metadata that enables the deferred-reaction UX without altering the classification pipeline. The 10:1 test-to-code ratio covers critical edge cases (dedup races, dual-event delivery, queue-full privacy leak). The queue-full fix from round 1 is correctly implemented. No new findings worth blocking on. Ship it.
