 - V2 BLOCKED migration 守門已補：`031-037` 必須存在且 group/world-readable，`database/momo.db` / `momo_data.db` / `momo_database.db` 迷惑檔不得回來。
 - `host_health_probes.chk_host_label_029` 不一致已有 migration 033 修補並補測試：必須重建 CHECK，且接受 `GCP-SSD`、`GCP-SSD-2`、`111 備援` 與兩個 110 Nginx proxy runtime labels。
 - `rag_query_log` / `learning_episodes` 缺 `embedding_signature` 已由 migration 034、ORM 欄位、RAG/learning 寫入路徑與 migration metadata 測試覆蓋。
-- `incidents` 雙欄相容與 `action_plans` source/status guardrails 已在 migration 036/037 與 `tests/test_auto_heal_safety.py` 覆蓋。

 - `services/agent_actions.py` 不是死碼：`services/event_router.py` 透過 `SAFE_ACTIONS` registry 動態執行 ADR-012 L2 actions，`tests/test_agent_actions.py` 與 `tests/test_event_router.py` 已覆蓋並通過。
