+# Java MVC 架构审计报告
+
+**审计对象**：Article (Model), ConsoleView (View), CrawlerController (Controller), Command家族 (Command层)
+
+**审计结论**：整体符合MVC分层，无严重越权，存在轻微旁路风险。
+
+## 各层审计详情
+
+| 层级 | 类名 | 职责 | 是否越权 | 说明 |
+|------|------|------|----------|------|
+| Model | Article | 纯数据载体，无业务逻辑 | ✅ 否 | 满足POJO规范 |
+| View | ConsoleView | 仅负责I/O，展示数据 | ⚠️ 轻度 | 持有List引用但未修改，属于正常依赖 |
+| Controller | CrawlerController | 命令路由，持有全局数据 | ✅ 否 | 职责明确，不直接操作Model细节 |
+| Command | CrawlCommand等 | 执行业务，直接修改List | ⚠️ 委托 | Controller主动授权，非越权但有潜在风险 |
+
+## 改进建议
+1. 使用 `Collections.unmodifiableList()` 向View提供只读视图
+2. 引入 `ArticleRepository` 统一管理数据修改操作
+3. 对Command增加权限预检（如只读/读写分离）
