+3. AI 架构审计（MVC 三层检查）
+发送给 AI 的指令模板：
+作为 Java 架构审计师，请检查我的 MVC 三层划分是否存在越权行为？
+
+我的项目结构：
+· Model：Article（数据实体）、Storage（数据存取）
+· View：ConsoleView（控制台输入输出）
+· Controller：CommandController（解析命令、调用 Model）
+
+请从以下角度审计：
+1. View 是否直接调用了 Model 层？（越权）
+2. Controller 是否做了 View 的工作？（职责混淆）
+3. Model 层是否包含了业务逻辑而非仅仅是数据存取？
+4. 各层之间的依赖方向是否正确？（View → Controller → Model）
