 **目标与步骤**
 
 - [ ] 按领域定义 Query/Command Protocol，不再使用通用 `OperFactory = Callable[[], Any]`。
 - [ ] 写 Port 由 `db/adapters` 创建单操作 Session/UoW；Oper 的 canonical 写方法只 stage/flush，
   读取方法仍可在调用方 Session 中查询。
-- [ ] 查询 Port 在 adapter Session 内映射为冻结 DTO/Projection，Application 和 API 不接收 ORM。
+- [x] Workflow 查询 Port 在 adapter Session 内映射为冻结 DTO/Projection，API、Agent、Chain、Scheduler、
+  Workflow runtime 和中心服务分享均不接收 ORM。
 - [ ] `ChainDataPorts`/`AgentDataPorts` 可暂时保留为兼容聚合器，但字段必须显式、可类型检查。
 - [ ] 以一个业务纵切面迁移并验证后，再迁移下一组，禁止一次替换所有 Oper。
 - [ ] 增加 AST 门禁，禁止向 `ChainDataPorts`、`AgentDataPorts` 和新的 canonical use-case service
