+# 智能出卷优化计划
+
+## 目标
+优化“智能出卷”页面，确保必须选择学生，提供智能的默认试卷名称，优雅地处理无历史数据的学生，并验证自动生成的兜底逻辑。
+
+## 需要用户审查
+> [!IMPORTANT]
+> **校验变更**：生成试卷时，**必须**选择学生。
+> **默认行为**：如果“试卷名称”留空，将自动生成为 `[学生姓名]_[日期]_[时间]_智能试卷`。
+
+## 建议变更
+
+### Filament Admin
+#### [修改] [IntelligentExamGeneration.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/app/Filament/Pages/IntelligentExamGeneration.php)
+- **校验**：在 `generateExam` 校验规则中添加 `'selectedStudentId' => 'required'`。
+- **默认试卷名称**：
+    - 移除 `paperName` 的 `required` 规则。
+    - 在 `generateExam` 中，检查 `paperName` 是否为空。如果为空，使用以下格式生成：`$studentName . '_' . now()->format('Ymd_His') . '_智能试卷'`。
+- **兜底逻辑**：
+    - 更新 `updatedSelectedStudentId`：
+        - 检查 `studentWeaknesses` 是否为空。
+        - 如果为空，发送 Filament 通知：“该学生暂无薄弱点数据，将随机生成题目或根据年级推荐”。
+        - 将 `filterByStudentWeakness` 设置为 `false`（或者保持启用但未选中任何知识点，提示用户手动选择）。
+
+#### [修改] [intelligent-exam-generation-simple.blade.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/resources/views/filament/pages/intelligent-exam-generation-simple.blade.php)
+- **UI 调整**：将“试卷名称”输入框移至“基本信息”部分的底部或不太显眼的位置，并标记为可选（占位符：“未填则自动生成”）。
+
+## 验证计划
+
+### 自动化测试
+创建一个新的特性测试文件：`tests/Feature/Livewire/IntelligentExamGenerationTest.php`
+
+- **测试 1：强制校验**
+    - 尝试在未选择 `selectedStudentId` 的情况下调用 `generateExam`。
+    - 断言验证错误。
+
+- **测试 2：默认试卷名称**
+    - 选择一个学生。
+    - 将 `paperName` 留空。
+    - 调用 `generateExam`（模拟服务调用）。
+    - 断言生成的试卷具有预期的默认名称。
+
+- **测试 3：无薄弱点兜底通知**
+    - 模拟 `LearningAnalyticsService` 返回空薄弱点。
+    - 触发 `updatedSelectedStudentId`。
+    - 断言发送了通知。
+
+### 试卷格式化与 PDF 生成
+#### [新增] [ExamPdfController.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/app/Http/Controllers/ExamPdfController.php)
+- 创建一个新的控制器来处理试卷预览/PDF 生成。
+- 方法 `show(Request $request, $paper_id)`:
+    - 获取试卷数据（通过 `QuestionBankService` 或直接查库）。
+    - 渲染视图 `pdf.exam-paper`。
+
+#### [新增] [resources/views/pdf/exam-paper.blade.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/resources/views/pdf/exam-paper.blade.php)
+- **布局**：标准 A4 试卷布局。
+- **头部**：老师姓名、学生年级、学生姓名、密封线。
+- **题型分类**：
+    - 一、选择题（每题带 OMR 标记圆圈，如 `( A ) ( B ) ( C ) ( D )` 或空心圆）。
+    - 二、填空题（留出填写下划线）。
+    - 三、解答题（留出足够空白）。
+- **标记位**：每题前添加 OMR 标记位，用于判卷和未来拍照 OCR 定位识别。
+- **样式**：使用 CSS `@media print` 确保打印效果良好。
+
+#### [修改] [routes/web.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/routes/web.php)
+- 注册路由：`Route::get('/admin/intelligent-exam/pdf/{paper_id}', [ExamPdfController::class, 'show'])->name('filament.admin.auth.intelligent-exam.pdf');`
+
+### 手动验证
+1.  **校验**：尝试在未选择学生的情况下点击“生成”。预期报错。
+2.  **默认名称**：选择学生，名称留空，点击“生成”。检查成功通知/数据库中生成的名称。
+3.  **无薄弱点**：选择一个已知无数据的学生（或模拟）。检查警告通知。
+4.  **PDF 预览**：生成试卷后，点击“导出 PDF”（或自动跳转），检查生成的页面是否符合中学试卷格式，是否包含判卷标记。

+# 题库管理优化方案
+
+## 目标
+优化 FilamentAdmin 中的题库管理界面，提升用户体验并利用新开发的后端能力（难度分级、题目类型）。
+
+## 需要用户审查
+- **UI 重构**：界面将迁移使用 DaisyUI 组件，打造更现代、更“高级”的外观。

+
+#### [修改] [QuestionManagement.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/app/Filament/Pages/QuestionManagement.php)
+- 添加公共属性 `$selectedType`。
+- 为生成模态框添加公共属性 `$generateDifficulty` 和 `$generateType`。
+- 更新 `questions()` 和 `meta()` 方法，将 `type` 加入筛选条件。
+- 更新 `executeGenerate()` 方法，将 `difficulty` 和 `type` 传递给 `QuestionBankService`。
+- 添加 `getQuestionTypeOptions()` 方法，为 UI 提供选项数据。
+
+#### [修改] [question-management.blade.php](file:///Volumes/T9/code/math/apis/FilamentAdmin/resources/views/filament/pages/question-management.blade.php)
+- **UI 重设计**：使用 DaisyUI 组件替换标准的 Tailwind 类：
+    - `card` 用于统计和筛选区域。
+    - `table` 配合 `table-zebra` 用于题目列表。
+    - `badge` 用于显示难度和类型指示器。
+    - `modal` 用于生成对话框。
+- **筛选器**：添加“题目类型”下拉菜单。
+- **生成模态框**：添加“难度”和“题目类型”的下拉菜单。
+- **视觉效果**：改进间距、排版和空状态展示。
+
+## 验证计划
+
+### 自动化测试
+- **单元测试**：
+    - 创建 `tests/Unit/Services/QuestionServiceApiTest.php`，验证 `listQuestions` 是否正确处理 `type` 和 `difficulty` 筛选参数。
+    - 创建 `tests/Feature/Livewire/QuestionManagementTest.php`，验证：
+        - 组件是否正确挂载。
+        - 筛选器是否更新 `questions` 属性。
+        - “生成”操作是否触发服务方法。
+- **浏览器测试**（使用 Agent 工具）：
+    - 验证“生成题目”模态框能否正常打开和关闭。
+    - 验证“题目类型”下拉菜单是否显示并可用。
+
+### 手动验证
+1.  **UI 检查**：
+    - 打开 `/admin/question-management`。
+    - 验证页面是否加载了新的 DaisyUI 样式。
+    - 检查统计卡片是否显示正确。
+2.  **筛选功能**：
+    - 选择一个“题目类型”（例如：选择题），验证列表是否更新。
+    - 选择一个“难度”，验证列表是否更新。
+3.  **生成功能**：
+    - 点击“生成题目”。
+    - 选择知识点、技能、难度和类型。
+    - 点击“开始生成”。
+    - 验证成功通知和任务状态监控。
+4.  **响应式检查**：
+    - 调整浏览器窗口大小，检查移动端视图兼容性。
+
+## 开发惯例：测试标准
+对于每一个新功能或优化：
+1.  **单元/功能测试**：必须创建或更新以覆盖业务逻辑。
+2.  **UI/页面测试**：验证渲染和响应式表现。
+3.  **功能测试**：验证端到端流程（例如：生成 -> 回调 -> 列表更新）。
