Documentation `docs/daily_read_feature_specification.md`, `docs/daily_read_interaction_flows.md`	新增“每日阅读”功能的设计规格与交互流程文档，涵盖架构、数据模型、状态机与序列图、测试策略与用例等。仅文档，无代码改动。
UI Loading Logic `lib/ui/daily_read/widgets/daily_read_screen.dart`	调整 CommandBuilder 的加载条件：从 lastValue == null 改为 lastValue != null 且为空列表时显示“正在加载今日推荐”。
ViewModel Tests `test/ui/daily_read/view_models/daily_read_viewmodel_test.dart`, `test/ui/daily_read/view_models/daily_read_viewmodel_test.mocks.dart`	新增 DailyReadViewModel 的单元测试与对应 Mockito 生成的仓库/用例/标签仓库桩类，覆盖首次/历史加载、开关标记/归档、打开 URL、加载标签、回调与资源释放等路径。
Widget Tests `test/ui/daily_read/widgets/daily_read_screen_test.dart`, `test/ui/daily_read/widgets/daily_read_screen_test.mocks.dart`	新增 DailyReadScreen 的 Widget 测试与 ViewModel 桩类，覆盖列表展示、加载态、庆祝态、信息渲染与交互调用等。
Repo Meta `CLAUDE.md`	新增一行文本指向路径“@.trae/rules/project_rules.md”。

52-89: 错误监听器可能造成内存泄漏

在 didChangeDependencies 中创建的错误监听器没有被正确清理。每次依赖变化时都会创建新的监听器，但旧的监听器不会被取消订阅。

建议将监听器移到 initState 中，并在 dispose 中取消订阅：

+  late StreamSubscription _loadErrorSubscription;
+  late StreamSubscription _toggleArchivedErrorSubscription;
+  late StreamSubscription _toggleMarkedErrorSubscription;

   @override
   void initState() {
     super.initState();
     // 初始化礼花控制器
     _confettiController = ConfettiController(
       duration: const Duration(seconds: 3),
     );
     // 设置书签归档回调
     widget.viewModel.setOnBookmarkArchivedCallback(_onBookmarkArchived);
+    
+    // 设置错误监听
+    _loadErrorSubscription = widget.viewModel.load.errors
+        .where((x) => x != null)
+        .listen((error) {
+      if (mounted) {
+        appLogger.e('加载书签失败', error: error);
+        ScaffoldMessenger.of(context).showSnackBar(
+          const SnackBar(content: Text('加载书签失败')),
+        );
+      }
+    });
+    // ... 其他错误监听器
   }

   @override
   void dispose() {
+    _loadErrorSubscription.cancel();
+    _toggleArchivedErrorSubscription.cancel();
+    _toggleMarkedErrorSubscription.cancel();
     // 释放动画控制器
     _confettiController.dispose();
     // 清除回调
     widget.viewModel.setOnBookmarkArchivedCallback(null);
     super.dispose();
   }
-
-  @override
-  void didChangeDependencies() {
-    super.didChangeDependencies();
-    // 移除所有错误监听器代码
-  }

196-208: 标签更新错误处理不一致

updateBookmarkLabels 使用了 catchError 来处理错误，而其他操作（如 toggleBookmarkMarked）通过 Command 的错误流处理。这种不一致的错误处理方式可能导致维护困难。

建议将 updateBookmarkLabels 也改为 Command 模式，保持错误处理的一致性：

-          onUpdateLabels: (bookmark, labels) {
-            widget.viewModel
-                .updateBookmarkLabels(bookmark, labels)
-                .catchError((error) {
-              if (context.mounted) {
-                ScaffoldMessenger.of(context).showSnackBar(
-                  SnackBar(
-                    content: Text('更新标签失败: $error'),
-                    duration: const Duration(seconds: 3),
-                  ),
-                );
-              }
-            });
-          },
+          onUpdateLabels: (bookmark, labels) =>
+              widget.viewModel.updateBookmarkLabels.execute(
+                UpdateLabelsParam(bookmark: bookmark, labels: labels),
+              ),

同时需要在 ViewModel 中添加相应的 Command 并在错误监听器中统一处理。

🧹 Nitpick comments (9)

CLAUDE.md (1)
1-1: 路径引用格式不标准，建议改为可点击的 Markdown 链接或明确的相对路径

当前仅以“@.trae/...”形式罗列，不是标准 Markdown 链接，工具或阅读器无法直接跳转。建议改为相对路径引用或显式链接，示例如下。
-@.trae/rules/project_rules.md
+/.trae/rules/project_rules.md
+
+或使用可点击的 Markdown 链接：
+- [项目规则](/.trae/rules/project_rules.md)
docs/daily_read_feature_specification.md (3)
35-56: 为代码块补充语言标识以通过 markdownlint（MD040）

该处为 ASCII 图示，建议标记为 text，避免 lint 报警并提升渲染一致性。类似的“无语言”代码块在文档中多处出现（例如 Line 89、108、129、152、161、169、178、270、390 等），可一并修正。
-```
+```text
 ┌─────────────────────────────────────┐
 │            UI层 (View)               │
 ...
 └─────────────────────────────────────┘
-```
+```
189-193: “加载状态”的触发条件表述与实现细节不完全一致，建议精确化

文档写“Command正在执行且结果为空”。根据本 PR 对 daily_read_screen.dart 的改动（whileExecuting 条件从 lastValue == null 调整为 lastValue != null && lastValue.isEmpty），建议将条件精确描述为“Command 执行中，且 lastValue 非空且为空集合”，避免与旧行为混淆。
-- **触发条件**: Command正在执行且结果为空
+- **触发条件**: Command 正在执行，且 lastValue != null 且 lastValue.isEmpty
126-126: 文档内联代码位置标注易随代码漂移失真，建议去除具体行号

使用 “daily_read_screen.dart:106-223” 这种行号锚定随代码演进容易失效，建议改为段落标题、方法名或“就近注释”的链接方式，或保留文件名+方法名不写行号。
-**代码实现**: `DailyReadScreen.render()` (`daily_read_screen.dart:106-223`)
+**代码实现**: `DailyReadScreen.render()`（详见 daily_read_screen.dart）
docs/daily_read_interaction_flows.md (2)
71-83: 为纯文本流程代码块补全语言标识（text）以满足 MD040

这三处为纯文本步骤，补上 “text” 语言标识，保持与全篇一致的规范。
-```
+```text
 开始 → Loading → 随机书签列表 → 操作书签 → 完成庆祝 → 再来一组
-```
+```

-```
+```text
 开始 → Loading → 历史书签列表 → 继续操作 → 完成庆祝
-```
+```

-```
+```text
 开始 → Loading → 错误页面 → 重试 → 正常流程
-```
+```
145-150: CommandBuilder 状态描述与代码变更保持一致，建议强调 lastValue 判定

此处已采用 “if lastValue.isEmpty” 的新语义，建议在文档上补一句“前提：lastValue != null”，以避免误解空引用情况。
-├── whileExecuting → Loading组件 (if lastValue.isEmpty)
+├── whileExecuting → Loading组件（前提：lastValue != null，且 lastValue.isEmpty）
test/ui/daily_read/view_models/daily_read_viewmodel_test.mocks.dart (1)

45-49: 提示：这是 Mockito 生成文件，请勿手改；确保测试桩返回值类型与接口一致

此文件对仓库接口的返回类型具备“权威性”。例如：

BookmarkRepository.toggleArchived/Marked → Future<ResultDart<void, Exception>>

BookmarkOperationUseCases.openUrl → Future<ResultDart<void, Exception>>

请在测试桩中严格返回 ResultDart<void, Exception>，否则将出现泛型不匹配导致的编译错误。

test/ui/daily_read/view_models/daily_read_viewmodel_test.dart (1)

349-384: “归档回调”用例断言较弱，建议补充可观测性或移除占位断言

当前仅设置回调并断言 expect(true, true)，无法证明回调行为。建议：

若 ViewModel 提供可触发归档完成的公开方法或事件，调用之并断言回调被触发；

或通过在 ViewModel 内暴露只读的回调是否已设置状态（供测试观察）；

若暂不可测，建议删除占位断言，改为验证“设置/清除回调”不抛异常的语义测试。

我可以帮你改造该用例，使其在不破坏封装的前提下具备有效断言。
test/ui/daily_read/widgets/daily_read_screen_test.dart (1)
228-270: 测试验证不完整

当前测试只验证了 setOnBookmarkArchivedCallback 被调用，但没有测试实际的书签操作（如归档、标记、打开URL等）是否正确触发相应的 Command。

建议增强测试以验证用户交互：
// 添加测试用户点击归档按钮
testWidgets('should call toggleBookmarkArchived when archive button is tapped',
    (WidgetTester tester) async {
  // ... 设置代码 ...
  
  await tester.pumpWidget(createWidgetUnderTest());
  await tester.pumpAndSettle();
  
  // 查找并点击归档按钮
  final archiveButton = find.byIcon(Icons.archive);
  expect(archiveButton, findsOneWidget);
  await tester.tap(archiveButton);
  
  // 验证 Command 被执行
  verify(mockDailyReadViewModel.toggleBookmarkArchived)
      .execute(testBookmark.bookmark);
});
