 - AI PMO 消息台列表接口补充：过滤短口水话 `query.read_only` 项（如“怎么样了/在吗”），保留后端记录但不下发前端收件流
 - AI PMO `signal_source.onboard` 入库规则：优先使用闭环摘要写入 `signals.summary`，闭环对话写入 `signals.content`，并在 `signals.strategic_analysis.source_context.implementation_modules` 持久化实现模块
+- 通用任务拆解接口（`POST /tasks/breakdown`）统一返回结构化任务业务对象，支持 `project_id/charter_id` 上下文与 Plane 同步
 - SSTC 信号列表接口（`GET /projects/{project_id}/signals`）标题生成规则：优先 `signals.title`，其次 `signals.summary`，最后回退 `signals.content` 去前缀文本
 - SSTC 宪章详情接口（`GET /projects/{project_id}/charters/{charter_id}`）`alignment_records[]` 补充 `user_name/confirmed_at`，用于前端展示“对齐成员 + 对齐时间”

+- SSTC 负责人推荐接口（`POST /projects/{project_id}/tasks/{task_id}/recommend-assignee`）直接消费 `required_skill_tag_ids` 语义，不再把技能 ID 当字符串
+- SSTC 任务更新接口（`PATCH /projects/{project_id}/tasks/{task_id}`）会把人工修改写入 `manual_overrides`，供后续 AI 重跑识别覆盖层
 - SSTC 发布创建接口（`POST /projects/{project_id}/releases`）新增已关联任务拦截：若 `task_ids` 命中历史发布计划已绑定任务，返回 `409` + `detail.task_ids`
 - 信号源编排补充：`SignalSourceOrchestrationService` 已停止运行时调用旧 command-first 执行链，统一改为“GLM 分析后直接调用服务写入”，编排结果字段对外收敛为 `execution`
 - 新增前端 API 调用：参考 `frontend/src/api/sstc.ts`
