+- SDK 回调需要同步确认的 Slack/Telegram/WeChatClawBot 保留同步调用，Discord 保留自有事件循环内的
+  异步调用；飞书、QQBot、企业微信继续立即返回，但任务改由现有 `ThreadHelper` 共享执行器承载，应用
+  关闭时由既有线程池生命周期等待，不再产生逐消息游离线程。HTTP 到达后仍由 `/api/v1/message` 的
+  TaskRegistry owner 执行消息主链。
+- 新门禁扫描全部宿主 `app/modules/**/*.py`，禁止渠道再次硬编码 `/api/v1/message`；新增渠道必须使用统一
+  ingress。source、token 统一通过 query encoder 处理，修复配置名含 `&` 等字符时被拆成额外参数的问题。
+- 兼容边界不变：七个渠道类、模块方法、配置字段、消息 payload、同步/异步 SDK 回调方式和
+  `/api/v1/message` HTTP 合同均未改；没有修改插件仓或向 SDK/Compat 新增宿主内部入口。

 ### 总体判断
 
 当前架构总体合理，已经从跨层混合的遗留单体收敛为**边界清晰的模块化单体**：
 
 - 继续采用单进程控制面是正确选择，不建议现在拆成微服务；插件、调度器、工作流、事件和数据库共享进程内状态，拆分会放大部署、事务和兼容成本。
 - `foundation/domain/runtime/adapters/application/chain/api/startup` 的职责方向基本成立；宿主架构基线、复杂度 ratchet、异步阻塞 ratchet 当前均通过。
-- 依赖图当前为 `805` 个 Python 模块、`6503` 条内部导入边；唯一非平凡 SCC 位于隔离的 TMDB 第三方移植包内部，不应为了指标归零重写。
+- 依赖图当前为 `806` 个 Python 模块、`6528` 条内部导入边；唯一非平凡 SCC 位于隔离的 TMDB 第三方移植包内部，不应为了指标归零重写。
 - 当前主要风险已经从“目录和依赖失控”转移到运行时协议、后台副作用的可靠性和遗留兼容面。换言之，下一阶段重点应是**语义收口和可验证性**，而不是继续搬文件或机械拆大文件。
 
 综合评价：架构方向可持续，生产可用性较高；可演进性仍处于中等水平。现阶段没有静态审计发现必须立即推倒重来的 P0 架构问题，但存在需要按 P1/P2 计划治理的真实债务。
