 ### Next Action (Must be Specific)
 
-**Immediate**: 创建 `ChatRequest.java`、`ChatResponse.java` AI 服务 DTO。
+**Immediate**: 执行 Phase 5 集成测试任务。
 
 **Details**:
-1. file: `src/main/java/com/wecom/robot/dto/ai/ChatRequest.java`
-2. action: 定义 ChatRequest DTO，包含 sessionId、currentMessage、channelType、history 字段
+1. task: TASK-040 集成测试
+2. action: 编写集成测试验证消息路由流程
 3. reference:
-   - `spec/ai-robot/design.md` 第 6.1 节（AI 服务调用）
-   - `spec/ai-robot/openapi.deps.yaml`（AI 服务契约）
+   - `spec/ai-robot/tasks.md` TASK-040 定义
 4. constraints:
-   - 字段与 openapi.deps.yaml 一致
-   - 包含映射方法 (InboundMessage → ChatRequest)
-   - 代码/注释必须包含 [AC-MCA-04-REQ] 标注
+   - 测试覆盖 InboundMessage → AI Service → OutboundMessage 完整流程
+   - 验证幂等性、熔断降级逻辑
