-## 必做任务完成情况
-
-### 1. ArticleRepository 完善 ✅
-- `add()`: 拒绝 null，抛出 IllegalArgumentException
-- `addAll()`: 拒绝 null 列表和列表中的 null 元素
-- `getAll()`: 返回 `Collections.unmodifiableList()` 不可变视图
-- `size()`: 返回文章数量
-- `clear()`: 清空所有文章
-
-### 2. AnalyzeCommand ✅
-- 复用策略解析但**不存储**到 Repository
-- 输出统计信息：文章总数、含作者/日期/内容的数量、使用的策略名称
-- 显示前 3 篇文章标题作为预览
-
-### 3. AI 架构审计 ✅
-
-#### 类签名汇总
-
-```java
-// Command 层
-interface Command { void execute(String[], ArticleRepository); }
-class CrawlCommand(ConsoleView, StrategyFactory)
-class AnalyzeCommand(ConsoleView, StrategyFactory)
-class ListCommand(ConsoleView)
-class HelpCommand(ConsoleView)
-class ExitCommand(ConsoleView)
-class HistoryCommand(ConsoleView, List<String>)
-
-// Controller 层
-class CrawlerController(ConsoleView, ArticleRepository, StrategyFactory)
-
-// Repository 层
-class ArticleRepository { add(), addAll(), getAll(), size(), clear() }
-
-// Strategy 层  
-interface CrawlStrategy { parse(), supports(), getPriority(), getPattern() }
-class StrategyFactory { getStrategy(url), register(), setDefaultStrategy() }
-class HnuNewsStrategy implements CrawlStrategy
-class BlogStrategy implements CrawlStrategy
-class NewsStrategy implements CrawlStrategy
-class GenericNewsStrategy implements CrawlStrategy (正则匹配)
-
-// Model 层
-class Article { title, url, content, author, publishDate }
-
-// View 层
-class ConsoleView
-```
-
-#### 架构审计结果
-
-| 检查项 | 结果 | 说明 |
-|--------|------|------|
-| **策略解耦** | ✅ 优秀 | 策略接口与实现完全分离 |
-| **Repository 封装** | ✅ 优秀 | 使用不可变视图 + null 防御 |
-| **开闭原则** | ✅ 达标 | 新增网站只需加策略类 + 注册一行 |
-| **依赖倒置** | ✅ 良好 | Command/Strategy 依赖抽象接口 |
-| **单一职责** | ✅ 达标 | 每个类职责清晰 |
-| **循环依赖** | ✅ 无 | 依赖链单向 |
-
-## 选做任务完成情况
-
-### 正则策略匹配 ✅
-- `GenericNewsStrategy` 使用正则表达式 `.*\.(news|press|article)s?\..*` 匹配新闻类网站
-
-### 默认策略 ✅
-- `StrategyFactory` 内置 `DefaultStrategy`，当没有匹配策略时返回空列表
-
-### 策略优先级 ✅
-- `CrawlStrategy` 接口新增 `getPriority()` 默认方法
-- `GenericNewsStrategy` 设置优先级为 5（高于默认优先级 1）
-- `StrategyFactory.getStrategy()` 遍历所有策略，选择优先级最高的匹配策略
-
-### 思考题答案
-
-**Q: 两个策略都 supports 同一 URL 时怎么办？**
-
-**A:** 采用**优先级机制**解决：
-
-1. 每个策略实现可以通过 `getPriority()` 返回优先级值
-2. `StrategyFactory.getStrategy()` 遍历所有策略时，记录最高优先级
-3. 如果多个策略都支持同一 URL，选择优先级最高的那个
-4. 如果优先级相同，选择最先注册的策略（遍历顺序决定）
-
-这种设计的优势：
-- 允许通用策略（如 `GenericNewsStrategy`）和专用策略（如 `HnuNewsStrategy`）共存
-- 专用策略可设置更高优先级，确保精确匹配优先
-- 通用策略作为兜底，提高系统兼容性
-
-## 命令功能对比
-
-| 命令 | 功能 | 是否存储 |
-|------|------|----------|
-| `crawl <url>` | 爬取并存储文章 | ✅ 是 |
-| `analyze <url>` | 分析文章统计（不存储） | ❌ 否 |
-| `list` | 列出已存储文章 | - |
-| `history` | 显示命令历史 | - |
-| `help` | 显示帮助 | - |
-| `exit` | 退出程序 | - |
-
-## 设计模式应用
-
-1. **策略模式**：`CrawlStrategy` 接口定义标准，各策略独立实现
-2. **工厂模式**：`StrategyFactory` 根据 URL 自动选择策略
-3. **Repository 模式**：数据访问封装，防御式编程
-4. **命令模式**：所有 Command 统一签名，易于扩展
