+### 长期整改阶段 43：Discord typing 异步 owner 与 shutdown 收口（2026-08-24）
+
+- Discord typing 原先在等待旧 task 进入终态前就删除字典 owner；`trigger_typing()` 阻塞超过一秒时，
+  新请求会覆盖仍运行的 task，模块停止也无法再取得它。现在同一实例通过异步 lifecycle 锁串行替换，
+  超时后保留 owner 并拒绝并行启动，task 只在自己的 `finally` 或已确认终态后释放登记。
+- client shutdown 先封住新增 typing，再按统一预算通知全部 owner；未自然结束的 task 会被取消并再次等待，
+  已完成 task 的异常也会被读取。Discord 长连接意外退出时，线程 runner 同样执行这条收尾路径，事件循环
+  不再直接关闭仍登记的 typing task。
+- `Discord` 类路径、构造参数、同步 `start_typing()`/`stop_typing()` 布尔合同、模块方法、消息格式和配置
+  字段均保持不变；V1/V2/V3 插件仍通过原模块能力调用。本阶段未修改插件仓、SDK 或 Compat 映射。
+
 ### 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**：
