+- [ ] TASK-023: 更新 SessionManagerService ⏳ [AC-MCA-11, AC-MCA-12]
 
 ### Next Action (Must be Specific)
 
-**Immediate**: 创建 `WeChatAdapter.java` 实现 ChannelAdapter 接口。
+**Immediate**: 重构 `MessageProcessService` 类。
 
 **Details**:
-1. file: `src/main/java/com/wecom/robot/adapter/WeChatAdapter.java`
+1. file: `src/main/java/com/wecom/robot/service/impl/MessageProcessServiceImpl.java`
-2. action: 将现有 WecomApiService 重构为 WeChatAdapter，实现 ChannelAdapter、ServiceStateCapable、TransferCapable、MessageSyncCapable 接口
+2. action: 重构 MessageProcessService，集成 MessageRouterService
 3. reference:
-   - `spec/ai-robot/design.md` 第 3.1 节（渠道适配器接口）
+   - `spec/ai-robot/design.md` 第 4.1 节（消息处理主流程）
-   - `src/main/java/com/wecom/robot/service/WecomApiService.java`（现有实现）
+   - `spec/ai-robot/design.md` 第 4.2 节（服务集成）
 4. constraints:
-   - 实现 ChannelAdapter 核心接口
+   - 必须注入 MessageRouterService
-   - 实现 ServiceStateCapable、TransferCapable、MessageSyncCapable
+   - 必须调用 MessageRouterService.processInboundMessage
-   - 现有功能保持兼容
+   - 代码/注释必须包含 [AC-MCA-08] 标注

   reason: 保持内部命名一致性，映射在 AiServiceClient 层处理
   impact: 避免后续 DTO 命名混乱
