## Checklist

### Completeness
- [x] FR-1: `"all"` added to `_VALID_TRIGGER_MODES` — 1-line change in config.py
- [x] FR-2: `bolt_app.event("message")` bound when `trigger_mode == "all"` — register() updated
- [x] FR-3: `extract_prompt_text()` dispatches between mention and passive paths — clean
- [x] FR-4: 👀 reaction suppressed for passive messages, deferred to post-triage — correct
- [x] FR-5: Dedup handles dual-event delivery — verified via tests, no new dedup code needed
- [x] FR-6: Startup warning for empty `allowed_user_ids` — static method on Daemon
- [x] FR-7: Startup warning for empty `triage_scope` — same method
- [x] FR-8: `should_process_message()` untouched — all filters still apply

### Quality
- [x] 318 tests pass, 0 failures
- [x] Code follows existing conventions
- [x] No new dependencies
- [x] No unrelated changes

### Safety
- [x] No secrets in committed code
- [x] No destructive operations
- [x] Error handling present (try/except on reactions, queue full path)

## Findings

VERDICT: approve

FINDINGS:
- [src/colonyos/slack.py]: `extract_prompt_text` is a clean routing function — mention detection via string containment `f"<@{bot_user_id}>"` is the right level of simplicity. No regex overhead, no false positive risk since Slack's encoding is deterministic.
- [src/colonyos/slack_queue.py]: The `is_passive` flag as a dictionary field flowing through the triage queue is the minimal-surface approach. It avoids subclassing, enums, or separate codepaths. The triage LLM itself is unchanged — it sees the same prompt text regardless of ingestion mode. This is correct: the model's classification should be content-dependent, not metadata-dependent.
- [src/colonyos/slack_queue.py]: Post-triage 👀 reaction for passive messages (line 341-345) fires after `triage_result.actionable` is confirmed but before queue item creation. This means if enqueue fails, the user sees 👀 but nothing happens. Pre-existing pattern for mention messages too (👀 fires before triage). Acceptable for v1 — the failure mode is rare and non-catastrophic.
- [src/colonyos/slack_queue.py]: Queue-full path correctly suppresses the user-visible warning for passive messages. This prevents the "why is the bot talking to me?" confusion. Good UX instinct.
- [src/colonyos/daemon.py]: `_warn_all_mode_safety` is a static method — good, no instance state needed, easily testable. Called once at startup in the right location (after config load, before register).
- [tests/]: 35+ new tests covering dedup races, dual-event delivery, passive prompt extraction, queue-full suppression, and startup warnings. The `threading.Event` synchronization pattern in triage worker tests avoids flaky sleeps.

SYNTHESIS:
This implementation demonstrates exactly the right instinct for working with an LLM-in-the-loop system: don't change the model's input, don't change the model's decision boundary, just change what you feed it and how you react to its output. The `is_passive` flag is pure control-plane metadata that never touches the triage prompt — the LLM classifies on content alone, which is correct. The two-phase reaction pattern (suppress 👀 on intake, add 👀 post-triage) is the right UX for a system where stochastic classification determines whether to surface. The ~45 lines of production code activate latent infrastructure with no new abstractions, no new failure modes, and no changes to the prompt engineering. The 10:1 test-to-code ratio covers the critical edge cases. Clean approval.
