+检查策略解耦与封装
+解耦方面：策略接口、工厂、使用者三层结构清晰，使用者与具体爬取算法完全解耦，新增 / 修改网站策略不影响上层命令与主程序，符合开闭原则；仅主程序存在少量硬编码注册，不影响整体解耦效果。
+2. 封装方面：策略实现细节、策略集合、数据模型均做到私有隐藏、接口暴露，外部只能通过规范接口交互，有效隔离内部变化，封装完整、安全。
+3. 整体架构：策略模式 + 命令模式 + 工厂模式组合，职责清晰、依赖单向、无循环依赖，具备良好的可维护性与扩展性。
+
+检查开闭原则达成度等
+审计结论：
+1. 开闭原则：项目采用命令模式 + 策略模式，新增命令只需实现Command2接口、新增策略只需实现CrawlStrategy2接口，无需修改主程序和工厂代码，完全符合对扩展开放、对修改关闭的原则。
+2. Repository 封装：ArticleRepository内部集合用private final修饰，外部仅能通过add/addAll方法添加，且返回的是Collections.unmodifiableList不可修改视图，同时对null做了严格防御，封装完备，数据安全。
+3. 循环依赖：所有组件均通过构造方法依赖注入，依赖方向为Main2 → 命令/工厂/仓库 → 模型，无反向依赖，不存在循环依赖问题。
+
+进阶探究题答案
+题目：不用工厂，直接用Map<String, CrawlStrategy>存起来 vs StrategyFactory的区别？
+直接用Map存储策略，虽然实现简单，但存在明显局限：
+1. 耦合度高：调用方需要直接维护Map的注册和匹配逻辑，新增策略时需要修改调用方代码，违反开闭原则。
+2. 扩展性差：无法在匹配逻辑中添加复杂规则（如优先级、默认策略、正则匹配），后续扩展困难。
+3. 可维护性低：匹配逻辑散落在业务代码中，难以统一管理和修改。
+而StrategyFactory将策略的注册、匹配逻辑封装为独立组件，调用方仅依赖工厂接口，无需关心具体实现；新增策略只需注册到工厂，不影响其他代码，既降低耦合，又提升了扩展性和可维护性，更符合面向对象设计规范。
