 ### 已知表治理清单（2026-09-10 审计）
 
-- `pipeline_conversations`：孤儿表——有真实读写（pipeline-service agent_loop_v2 的 sor.C
-  落盘、驾驶舱 v2 历史加载），但**全平台无 models JSON 定义**，建表靠历史残留，
-  新库部署会缺表。待补 models 定义（归属 pipeline-service 或 core 待定）。
-- `sd_conversations`：死表——pipeline-sdlc 有 models 定义，但 2026-08-01 后全平台零写，
-  仅存 SELECT/DELETE/孤儿巡检引用。驾驶舱 v2 已改用 pipeline_conversations。待删除决议。
+全部办结（2026-09-10 批评会决议，用户认可）：
+
+- `pipeline_conversations`：孤儿表→已归籍 pipeline-service（models 定义 b8a2aea + collation 统一 m0022）。
+- `sd_conversations`：死表→models 定义已删、project_capability 4 处引用已清、DROP 见 m0027（32 行备份后删）。
+- 其余 10 张孤儿/死表一次清零：5 张归籍补定义（bid_analysis_history、bid_cost_benefit→bidding；pipeline_agent_instances、pipeline_agent_settings、pipeline_project_agents→service），4 张死表 DROP + 权限清理见 m0027（非破坏的 collation/索引收敛在 m0026），pipeline_deploy_ledger 为 dmig 自建台账豁免（table_doctor 白名单）。
