.trae/documents/Implementation Plan for User Group Management System.md

@@ -0,0 +1,45 @@
+I will implement the User Group Management System as follows:
+
+### 1. Database Schema Changes
+*   **New Table `user_groups`**: Stores group info (id, name, description, is_system, created_at).
+*   **New Table `user_group_members`**: Links users to groups (group_id, user_id, created_at).
+*   **Update `exam_tasks`**: Add `selection_config` column to store the original assignment logic (e.g., which groups were selected).
+*   **Migration Script**: Create `scripts/migrate_user_groups.ts` to initialize tables and the default "All Users" group, adding all existing users to it.
+
+### 2. Backend Implementation (Node.js/Express)
+*   **Models**:
+    *   `UserGroupModel`: CRUD for groups, membership management, and "All Users" logic.
+    *   Update `UserModel`: Methods to fetch user's groups.
+    *   Update `ExamTaskModel`: Handle `selection_config`.
+*   **Controllers**:
+    *   `UserGroupController`: API endpoints for group management.
+    *   Update `UserController`:
+        *   Auto-add new users to "All Users" group.
+        *   Handle group assignment updates.
+    *   Update `ExamTaskController`:
+        *   Support assigning tasks by `groupIds`.
+        *   Logic to flatten groups + users and remove duplicates.
+*   **API Routes**: Register new `/api/user-groups` endpoints.
+
+### 3. Frontend Implementation (React)
+*   **User Management (`UserManagePage`)**:
+    *   Add a **Tab Interface**: "User List" vs "User Group Management".
+    *   **Group Management Tab**: List groups, Create/Edit/Delete groups (with "All Users" protection).
+    *   **User List**: Show assigned groups in the table.
+    *   **User Edit Modal**: Add a Multi-select component to manage user's groups.
+*   **Exam Task Assignment (`ExamTaskPage`)**:
+    *   Update Assignment Modal.
+    *   Add **User Group Selection** (Multi-select).
+    *   Show "Selected Users" count and "Selected Groups" count.
+    *   Implement logic to calculate total unique users before saving.
+
+### 4. Business Logic & Constraints
+*   **"All Users" Group**:
+    *   Created automatically.
+    *   Cannot be deleted or renamed.
+    *   All new users join automatically.
+    *   Users cannot be removed from it manually.
+*   **Audit**: Record group membership changes (log to database/console as appropriate).
+*   **Permissions**: Ensure only admins can manage groups (reusing existing Admin middleware).
+
+I will start by creating the migration script and updating the backend models.

.trae/documents/Modify User Selection List Style and Sorting.md

@@ -0,0 +1,24 @@
+I will modify the "Participating Users" selection component in `src/pages/admin/ExamTaskPage.tsx` to support displaying up to 50 users with a scrollbar and automatic sorting.
+
+**Implementation Steps:**
+
+1. **Add Custom CSS (`src/index.css`):**
+
+   * Add a `.user-select-scrollable` class to handle the scrollbar logic for the Ant Design Select component.
+
+   * Set `max-height` (e.g., 120px) and `overflow-y: auto` for the `.ant-select-selector` to ensure it scrolls when many users are selected.
+
+2. **Update Component (`src/pages/admin/ExamTaskPage.tsx`):**
+
+   * **Remove Restrictions:** Remove `maxTagCount={3}` and `maxTagPlaceholder` props from the `Select` component to allow all selected users to be displayed.
+
+   * **Apply Style:** Add `className="user-select-scrollable"` to the `Select` component.
+
+   * **Implement Sorting:** Add a `normalize` function to the parent `Form.Item`. This function will intercept value changes and sort the selected User IDs alphabetically by their names (using `localeCompare` for Chinese support).
+
+3. **Verification:**
+
+   * Ensure the development server is running.
+
+   * Provide a preview URL for you to test the changes (User selection should expand, show a scrollbar after filling up, and selected names should automatically sort).

+I will modify `src/pages/admin/ExamTaskPage.tsx` to optimize the user selection display and the table layout.
+
+**Implementation Steps:**
+
+1. **Optimize User Selection (`Select`** **Component):**
+
+   * Add `optionLabelProp="label"` to the `Select` component.
+
+   * Update `Select.Option` to include a `label={user.name}` prop.
+
+   * This ensures that while the dropdown still shows "Name (Phone)" for clarity, the selected tags in the input box will only show "Name", saving significant space.
+
+2. **Optimize Table Layout (`columns`** **Configuration):**
+
+   * **Task Name & Subject:** Add specific `width` properties (e.g., `200px` and `150px`) and `ellipsis: true` to the "Task Name" and "Exam Subject" columns to give them more space and handle overflow gracefully.
+
+   * **Action Column:** Change the `<Space>` component in the "Action" column to `<Space direction="vertical" size={0}>`. This will stack the "Edit", "Report", and "Delete" buttons vertically, reducing the column's required width. I will also set a fixed, narrower width for this column.
+
+3. **Verification:**
+
+   * Verify that selected users in the form only show their names.
+
+   * Verify that the table "Action" column is narrower with vertically stacked buttons.
+
+   * Verify that "Task Name" and "Exam Subject" columns are wider.

+# UI视觉升级与品牌化实施方案
+
+本计划旨在对现有系统进行全面的视觉升级，重点引入全新的色彩规范（Mars Green）并实施严格的Logo展示规范。
+
+## 1. 视觉系统构建 (Visual System)
+**目标**: 建立以"Mars Green"为核心的科技感视觉体系。
+- **色彩规范 (Colors)**:
+  - **主色 (Primary)**: `#008C8C` (Mars Green)。
+  - **辅助色 (Secondary)**: `#00A3A3` (明亮), `#006666` (深沉)。
+  - **中性色**: 调整灰度色阶，配合青色调，营造冷峻科技感。
+  - **操作**: 更新 `tailwind.config.js` 的 `colors` 配置，更新 `src/main.tsx` 的 Ant Design `token`。
+- **Logo 占位组件 (Brand Identity)**:
+  - **组件化**: 创建 `src/components/common/Logo.tsx`。
+  - **规格**:
+    - `Primary`: 100x40px (Nav Left), 带 "Placeholder" 水印 (15% opacity)。
+    - `Secondary`: 80x30px (Footer Right), 简化版。
+  - **可配置性**: 使用 CSS 变量或 Props 控制路径，预留未来替换接口。
+  - **响应式**: 移动端自动切换为图标模式或缩小比例。
+
+## 2. 全局样式配置 (Global Configuration)
+- **Ant Design 主题**:
+  - `colorPrimary`: `#008C8C`。
+  - `borderRadius`: `8px` (圆角适中，兼顾亲和力与专业感)。
+  - `fontFamily`: 优先使用系统字体栈，配合 `Inter`。
+- **排版系统**:
+  - 建立 8px 网格间距系统 (Spacing Token)。
+  - 优化全局字号与行高。
+
+## 3. 布局与组件改造 (Layout & Components)
+**目标**: 植入品牌元素，优化空间布局。
+- **通用布局组件 (Layouts)**:
+  - **`AdminLayout.tsx`**:
+    - 顶部导航栏左侧植入 100x40px Logo 区域。
+    - 底部增加 Footer 区域，右侧植入 80x30px Logo。
+    - 调整侧边栏配色，呼应主色调。
+  - **用户端页面 (`HomePage.tsx`)**:
+    - 重构页面结构，从单一居中容器改为 `Header - Content - Footer` 结构。
+    - 确保 Logo 在首屏清晰可见。
+- **组件样式微调**:
+  - **Button**: 增加高度至 40px/48px，增强点击感。
+  - **Card**: 优化阴影 (Shadow) 和圆角，减少视觉噪点。
+  - **Input**: 统一高度和边框颜色。
+
+## 4. 实施步骤
+1.  **核心配置**: 修改 `tailwind.config.js` 和 `src/main.tsx`，确立 Mars Green 主调。
+2.  **组件开发**: 实现 `Logo` 组件。
+3.  **布局重构**:
+    - 改造 `AdminLayout`，加入 Header/Footer Logo 区域。
+    - 改造 `HomePage`，加入 Header/Footer 结构。
+4.  **样式覆盖**: 遍历主要页面，替换旧的颜色类名 (如 `text-blue-600` -> `text-primary-600`)，调整间距。
+5.  **验证**: 检查 Logo 尺寸、位置及水印效果，验证移动端适配。
+
+## 5. 交付物
+- 更新后的 UI 代码库。
+- 响应式设计规范文档 (含 Logo 使用规范)。
+- 视觉走查清单。
+
+请确认执行。

@@ -0,0 +1,31 @@
+我将修改 `src/pages/admin/AdminDashboardPage.tsx` 文件，将原本逻辑有误且样式陈旧的实心饼图升级为**现代化的环形图 (Donut Chart)**。
+
+### 具体修改计划：
+
+1.  **修正数据计算逻辑**：
+    *   目前的逻辑中，“已完成”、“合格”、“优秀”存在包含关系，导致饼图数据重叠。
+    *   **新逻辑**（确保各部分互斥且总和为总人数）：
+        *   **未完成** (`Incomplete`): 总人数 - 已完成
+        *   **不及格** (`Failed`): 已完成 - 合格
+        *   **合格** (`Passed`): 合格 - 优秀 (即“合格但未达优秀”)
+        *   **优秀** (`Excellent`): 优秀人数
+    *   这样四个部分加起来正好等于总人数，能准确反映分布情况。
+
+2.  **升级图表视觉效果**：
+    *   **环形设计**：设置 `innerRadius={40}` 和 `outerRadius={60}`，将饼图变为环形图，视觉上更轻量现代。
+    *   **颜色优化**：使用 Ant Design 标准色板：
+        *   优秀: `#fa8c16` (橙色)
+        *   合格: `#52c41a` (绿色)
+        *   不及格: `#ff4d4f` (红色)
+        *   未完成: `#f0f0f0` (浅灰，降低视觉干扰)
+    *   **交互优化**：
+        *   移除杂乱的外部连线 Label，保持界面整洁。
+        *   优化 `Tooltip`，鼠标悬停时显示具体人数和占比。
+        *   在环形图中心添加文字（如“总计”或完成率），充分利用空间。
+
+3.  **代码实现**：
+    *   修改 `AdminDashboardPage.tsx` 中的 `pieData` 生成逻辑。
+    *   更新 `Recharts` 的 `Pie` 组件属性配置。
+
+### 预期效果：
+新的环形图将清晰地展示考试的整体进度和成绩分布，消除数据重叠带来的误解，并且在视觉上更加美观、专业。

+# Custom Focus Duration
+
+## Context
+- 当前考试页面 `src/pages/QuizPage.tsx` 仅实现倒计时与提交逻辑，未对“离开页面/切换标签页”进行任何约束或记录。
+- 管理端已有系统配置能力（`system_configs` 表 + `SystemConfigModel` + 管理端配置页），适合用于落地“可配置的离开页面容忍时长”。
+
+## Goals / Non-Goals
+- Goals:
+  - 支持管理员配置“考试进行中允许离开页面的累计时长（秒）”，并在考试页面实时生效。
+  - 当累计离开页面时长超过阈值时，系统按统一规则处理（默认：自动交卷并提示原因）。
+  - 配置缺省时不改变现有考试流程（默认关闭该约束）。
+- Non-Goals:
+  - 不实现更复杂的反作弊能力（如摄像头、屏幕录制、进程检测、强制全屏、OS 级别限制）。
+  - 不新增外部依赖服务或第三方 SaaS。
+
+## Decisions
+- 决策：将“焦点容忍时长”作为系统配置项持久化，默认关闭。
+  - 方案：在 `system_configs` 中新增配置类型（例如 `quiz_focus_config`），形如 `{ enabled: boolean, maxUnfocusedSeconds: number }`。
+  - 理由：与现有配置存储模式一致；默认关闭可避免对现有行为产生破坏性变更。
+- 决策：焦点离开判定使用浏览器 Page Visibility 能力（`document.hidden`/`visibilitychange`）并累计离开时长。
+  - 理由：实现成本低、跨浏览器兼容性较好、无需引入新技术栈。
+- 决策：超阈值处理默认“自动交卷”。
+  - 理由：规则清晰、可验证；与现有“时间到自动交卷”路径类似，便于复用提交逻辑。
+
+## Risks / Trade-offs
+- 误判风险：移动端切后台、系统弹窗等可能导致短暂 `hidden`。
+  - 缓解：默认关闭；管理员可设置更宽松阈值（例如 10–30 秒）。
+- 可绕过：用户可在同一标签内切换窗口但仍保持可见，或使用分屏。
+  - 缓解：该能力只覆盖“标签页不可见”的场景；不将其描述为强反作弊。
+- 体验影响：过严阈值会导致误触发交卷。
+  - 缓解：在 UI 明确提示该规则与当前阈值；触发前可选“超阈值预警”作为后续增强。
+
+## Migration Plan
+- 以“默认关闭”的配置发布（`enabled: false`），确保升级后不影响现有考试行为。
+- 管理端提供配置入口后，由管理员在需要的考试场景手动开启并设置阈值。
+- 回滚策略：关闭 `enabled` 即可恢复为原行为。
+
+## Open Questions
+- 是否需要将“违规触发记录”写入答题记录（`quiz_records`）以便统计与审计？
+- 超阈值动作是否需要支持可配置（仅警告 / 记录违规 / 自动交卷）？

+# Change: 题库管理新增文本导入页面（`|` 分隔）与覆盖/增量导入
+
+## Why
+当前题库导入主要依赖 Excel 文件，使用门槛较高且不便于快速整理题目文本。需要提供“粘贴文本 → 解析预览 → 审阅删除 → 一键导入”的流程以提升题库维护效率。
+
+## What Changes
+- 新增管理端“文本导入题库”独立页面：
+  - 文本输入框粘贴题库文本
+  - 解析后生成题目列表供审阅，支持删除条目
+  - 支持导入模式：覆盖式导入、增量导入（按题目内容判断重复并覆盖）
+- 所有题目新增字段“解析”（0~255 字符串），用于详细解析该题的正确答案
+- 文本导入格式调整：

+# Change: 用户端考试页面流程与统计能力
+
+## Why
+当前用户端已具备基础登录、任务列表、生成试卷、交卷与结果页能力，但缺少“按用户匹配考试计划、限次控制、弃考、过程约束、历史回看、个人统计与操作日志”等完整考试流程要求，导致管理端考试任务难以按规则落地执行。
+
+## What Changes
+- 新增用户端登录会话规则与登出能力（基于现有用户数据模型）
+- 新增用户端考试计划（考试任务）匹配与展示规则（仅展示当前时间有效且分派给当前用户的任务）
+- 新增考试次数限制（每个任务最多 3 次）与最高分规则（取历史最高分为最终分）
+- 新增考试过程控制：弃考（二次确认、清理进度、不计入统计、次数不减少）、答题进度自动保存、题目导航
+- 新增考试交互约束：考试中不展示评分信息，交卷后展示评分详情
+- 新增用户端个人统计与可视化展示（完成率/合格率/优秀率）
+- 新增关键操作审计日志（登录、生成试卷、弃考、交卷、查看历史）
+
+## Impact
+- Affected specs:
+  - `openspec/specs/api_response_schema.yaml`（所有新增/调整接口继续使用统一响应包裹）
+  - `openspec/specs/auth_rules.yaml`（用户端会话与接口访问规则将被补齐为可实现状态）
+  - `openspec/specs/database_schema.yaml`（可能需要新增日志表/补齐考试次数与历史聚合查询）
+- Affected code (expected):
+  - Frontend: `src/pages/HomePage.tsx`, `src/pages/UserTaskPage.tsx`, `src/pages/SubjectSelectionPage.tsx`, `src/pages/QuizPage.tsx`, `src/pages/ResultPage.tsx`, `src/contexts/*`

+# 管理员登录记录与仪表盘/统计页改造
+
+## Context
+- 管理端登录页存在“最近登录记录”体验需求，且需要确保不会保存失败登录或敏感信息（如密码）。
+- 管理端仪表盘/统计页存在通过 `fetch` 手写请求与鉴权头、与 `src/services/api.ts` 统一封装并存的情况，导致代码重复且行为不一致。
+- 管理端仪表盘指标卡片与统计模块需要重构：新增可点击的统计卡片与饼图展示，并新增“历史考试任务统计”（含分页与后端分页查询接口）。
+
+## Goals / Non-Goals
+- Goals:
+  - 管理员登录页仅在登录成功时写入最近登录记录（用户名 + 时间戳），且不保存密码。
+  - 管理端页面统一使用现有的 `api`/`adminAPI`/`quizAPI` 访问后端，避免重复拼接 token 与重复处理响应格式。
+  - 管理员仪表盘指标卡片重构：
+    - 移除现有卡片：答题记录、平均得分。
+    - 新增总用户数：实时数字；点击跳转 `/admin/users`。
+    - 新增题库统计：饼图展示各题目类别占比；点击跳转 `/admin/question-bank`。
+    - 新增考试科目：显示当前活跃科目数量；点击跳转 `/admin/subjects`。
+    - 新增考试任务：饼图展示任务状态分布（已完成/进行中/未开始）；点击跳转 `/admin/exam-tasks`。
+  - 统计功能调整：移除题型正确率统计模块。
+  - 新增历史考试任务统计：
+    - 展示所有历史考试任务统计（非仅当前有效任务）。
+    - 排序：按结束时间倒序。
+    - 分页：每页 5 条，支持前后翻页。
+    - 字段：与“当前有效考试任务统计”字段保持一致。
+    - 需新增后端分页查询接口以支撑上述分页与排序。
+  - 新增未开始考试任务统计：
+    - 展示未开始的考试任务（开始时间晚于当前时间）。
+    - 排序：按开始时间正序。
+    - 分页：每页 5 条，支持前后翻页。
+    - 字段：与“当前有效考试任务统计”字段保持一致。
+    - 需新增后端分页查询接口以支撑上述分页与排序。
+- Non-Goals:
+  - 不调整管理员鉴权机制（`adminAuth` 仍为简化实现）。
+  - 不新增第三方图表库或引入新的前端数据层框架。
+
+## Decisions
+- 决策：复用 `src/services/api.ts` 的 axios 实例与拦截器，统一处理 token 注入与 `success`/`message` 响应格式。
+  - 理由：仓库已存在稳定封装，减少重复与差异。
+- 决策：最近答题记录使用现有 `/api/quiz/records` 接口拉取（分页参数 `page=1&limit=10`）。
+  - 理由：后端已实现管理员分页接口；前端无需再手写 `fetch`。
+- 决策：新增的仪表盘跳转路由以不破坏现有路由为前提，通过新增别名路由满足新路径需求。
+  - `/admin/question-bank` 作为 `/admin/questions` 的别名路由。
+  - `/admin/exam-tasks` 作为 `/admin/tasks` 的别名路由。
+- 决策：仪表盘新增数据优先由后端聚合提供，减少前端全量拉取与二次计算。
+  - 题库类别占比：按题目类别聚合统计数量（用于饼图）。
+  - 活跃科目数量：以“当前时间存在有效考试任务”的科目去重统计。
+  - 任务状态分布：以任务开始/结束时间与当前时间对比划分已完成/进行中/未开始并聚合计数。
+- 决策：新增历史考试任务统计分页接口，返回统一响应包裹并携带 `pagination`。
+  - 路径建议：`GET /api/admin/tasks/history-stats?page=1&limit=5`。
+  - 返回结构：`{ success: true, data: ActiveTaskStat[], pagination: { page, limit, total, pages } }`。
+- 决策：新增未开始考试任务统计分页接口，返回统一响应包裹并携带 `pagination`。
+  - 路径建议：`GET /api/admin/tasks/upcoming-stats?page=1&limit=5`。
+  - 返回结构：`{ success: true, data: ActiveTaskStat[], pagination: { page, limit, total, pages } }`。
+
+## Risks / Trade-offs
+- 统一到 axios 封装后，错误提示将由拦截器抛错路径主导。
+  - 缓解：在页面层使用 `message.error(error.message)`，保持用户感知一致。
+- 历史任务统计若逐任务计算报表可能产生额外数据库开销。
+  - 缓解：按分页限制任务数；必要时在模型层优化聚合 SQL 或缓存计算结果（仅服务端内存，不落地到业务表）。
+
+## Migration Plan
+- 前端无数据迁移：登录记录仍存储在 localStorage，仅调整写入触发条件与读取方式。
+- 回滚策略：恢复为原先 `fetch` 调用与原登录记录写入逻辑。

 # Project Context
 
 ## Purpose
-[Describe your project's purpose and goals]
+本项目是一个面向“考试/答题/问卷”场景的 Web 应用，支持用户免注册答题、题库管理、考试科目与任务分派、答题记录与统计分析，并提供管理员端的日常运营能力（题库/科目/任务/用户管理、导入导出、配置管理等）。
 
 ## Tech Stack
-- [List your primary technologies]
-- [e.g., TypeScript, React, Node.js]
+- 前端：React 18 + TypeScript + Vite + React Router + Ant Design + Tailwind CSS + Zustand
+- 后端：Node.js + Express + TypeScript（`tsx` 运行，`nodemon` 热重载）
+- 数据库：SQLite3（本地文件数据库）
+- 文件处理：Multer（上传）+ XLSX（Excel 导入/导出）
+- 其他：Axios（HTTP）、UUID、dotenv、concurrently
 
 ## Project Conventions
 
 ### Code Style
-[Describe your code style preferences, formatting rules, and naming conventions]
+- 语言与模块：项目为 ESM（`package.json:type=module`），前后端均以 TypeScript 为主。
+- 命名风格：前端组件/页面使用 PascalCase；变量与函数使用 camelCase；路由资源使用 kebab 或小写复数（以现有接口为准）。
+- 错误返回：后端接口大多返回 `{ success: boolean, message?: string, data?: any, pagination?: any }` 的统一结构（见 `api/middlewares/index.ts` 的 `responseFormatter` 相关逻辑与各控制器实现）。
+- 代码组织：尽量沿用现有分层与文件结构，不引入新的技术栈或重复实现。
 
 ### Architecture Patterns
-[Document your architectural decisions and patterns]
+- 前端：`src/pages` 放页面级组件；`src/components` 放复用组件；`src/contexts` 存放上下文状态；`src/services/api.ts` 封装接口访问；`src/utils` 存放通用工具。
+- 后端：以 `api/server.ts` 为主要 API 入口，使用 Express Router 组织路由；业务按 `controllers/`（HTTP 处理）与 `models/`（数据库访问与领域逻辑）分层。
+- 数据库初始化：`api/database/init.sql` 负责建表/初始化；应用启动时由 `initDatabase()` 执行初始化与连接。
+- 环境变量：使用 `dotenv` 加载 `.env`；端口默认 `3001`（可通过 `PORT` 覆盖）；SQLite 文件路径可通过 `DB_PATH` 覆盖。
+- 服务端口：
+  - 前端开发：`http://localhost:5173/`
+  - 后端开发：`http://localhost:3001/api`
+- 本地代理：Vite 将 `/api` 代理到 `http://localhost:3001`（见 `vite.config.ts`），前端请求统一走相对路径 `/api`（见 `src/utils/request.ts`）。
+
+### Runbook
+- 安装依赖：`npm install`
+- 启动开发：`npm run dev`（并行启动 `dev:api` 与 `dev:frontend`）
+- 类型检查：`npm run check`
+- 生产构建：`npm run build`
+- 启动生产：`npm start`（运行 `dist/api/server.js` 并托管 `dist/` 下静态文件）
+- 目录约定：前后端构建产物当前共享 `dist/` 目录；若构建过程出现互相覆盖，需要调整构建输出目录或构建顺序。
+
+### OpenSpec 工作流（本仓库约定）
+- 查看现有规格：`openspec list --specs`
+- 查看变更提案：`openspec list`
+- 校验变更提案：`openspec validate <change-id> --strict`
+- 交互式选择：`openspec show`、`openspec validate`
 
 ### Testing Strategy
-[Explain your testing approach and requirements]
+- 优先保证：`npm run check`（TypeScript 类型检查）与 `npm run build`（生产构建）可通过。
+- 目前仓库存在 `test/` 下的接口测试样例（Jest + Supertest 风格），但 `package.json` 未提供统一的 `test` 脚本与相关依赖声明时需先补齐再启用。
+- 功能新增或行为变更应补充可执行的自动化测试（单测/接口测试均可），并避免引入仅用于一次性验证的脚本逻辑进入生产代码路径。
 
 ### Git Workflow
-[Describe your branching strategy and commit conventions]
+- 建议以功能为单位创建分支，保持提交粒度清晰（一个提交聚焦一个主题）。
+- 与规范相关的变更（需求/行为/接口/数据结构）优先通过 OpenSpec 变更提案（`openspec/changes/<change-id>/`）描述，再进入实现。
 
 ## Domain Context
-[Add domain-specific knowledge that AI assistants need to understand]
+- 核心领域对象：
+  - 用户（User）：通过姓名 + 手机号进入系统；密码字段目前存在且为敏感信息。
+  - 题库（Question / QuestionCategory）：支持题目类别、题型（单选/多选/判断/文本）、导入导出。
+  - 考试科目（ExamSubject）：描述抽题规则（题型比例、类别比例、总分、时长）。
+  - 考试任务（ExamTask）：面向一组用户分派某科目，在开始/结束时间范围内有效；支持按用户与按用户组混合选择，并在服务端进行去重；原始选择通过 `selectionConfig`（JSON 字符串）保留。
+  - 答题（QuizRecord / QuizAnswer）：记录得分、正确数、明细答案等。
+  - 系统配置（SystemConfig）：保存抽题配置、管理员账号配置等。
+  - 用户组（UserGroup / UserGroupMember）：
+    - 内置“全体用户”系统组：新用户自动加入；不可删除/不可修改；用户不可主动退出。
+    - 注意：用户组相关功能（管理、成员关系、考试任务按组分派与混合选择）目前已实现但处于未测试状态，且缺少“用户组变更审计日志”能力。
+- 管理员能力：管理员登录目前为简化实现（固定账号与 token），并通过 `adminAuth` 中间件保护管理接口。
 
 ## Important Constraints
-[List any technical, business, or regulatory constraints]
+- 鉴权现状：`adminAuth` 当前为简化放行逻辑，`/api/admin/login` 返回固定 token；生产环境需要替换为真实鉴权（例如 JWT 校验）并在前后端一致落地。
+- 安全：用户密码目前存在明文存储/传输路径的风险，属于待整改项；任何日志与导出都应避免泄露敏感信息。
+- 数据库：使用 SQLite 文件库，适合轻量/单机；并发与事务能力有限，涉及批量写入或一致性要求时需谨慎设计。
 
 ## External Dependencies
-[Document key external services, APIs, or systems]
+- 当前不依赖外部第三方服务；主要外部依赖为本地 SQLite 数据文件（`data/` 目录）与 Excel 文件导入导出能力。
+- 若未来接入统一登录、对象存储、日志审计等外部服务，应在 OpenSpec 规范中补充依赖与接口约束。

+| #8E24AA | rgb(142, 36, 170) | 深紫色 | 4.83 | ✅ | ❌ |
+
+## 4. API 接口
+
+### 4.1 核心接口
+
+| 函数名 | 功能描述 | 参数 | 返回值 |
+|-------|---------|------|--------|
+| `getCategoryColor` | 获取完整的颜色信息 | `category: string` | `ColorInfo` 对象 |
+| `getCategoryColorHex` | 获取十六进制颜色值 | `category: string` | 十六进制颜色字符串 |
+| `getCategoryColorRgb` | 获取RGB颜色对象 | `category: string` | `{ r: number; g: number; b: number }` |
+| `getCategoryColorRgbString` | 获取RGB颜色字符串 | `category: string` | RGB字符串（如：`rgb(255, 0, 0)`） |
+| `getCategoryColorName` | 获取颜色名称 | `category: string` | 颜色名称字符串 |
+| `isCategoryColorAccessible` | 检查颜色可访问性 | `category: string` | 包含WCAG标准检查结果的对象 |
+| `getAllCategoryColors` | 获取所有颜色映射 | 无 | 完整的颜色映射对象 |
+| `addCategoryColor` | 添加新的颜色映射 | `category: string`, `colorInfo: ColorInfo` | 无 |
+| `updateCategoryColor` | 更新颜色映射 | `category: string`, `colorInfo: Partial<ColorInfo>` | 无 |
+| `removeCategoryColor` | 删除颜色映射 | `category: string` | 无 |
+
+### 4.2 使用示例
+
+```typescript
+// 导入颜色管理系统
+import { getCategoryColorHex, getCategoryColorRgbString } from './categoryColors';
+
+// 在组件中使用
+const CategoryBadge = ({ category }: { category: string }) => {
+  return (
+    <span 
+      style={{
+        backgroundColor: getCategoryColorHex(category),
+        color: '#ffffff',
+        padding: '4px 8px',
+        borderRadius: '4px',
+        fontSize: '12px'
+      }}
+    >
+      {category}
+    </span>
+  );
+};
+
+// 在图表中使用
+const ChartComponent = ({ data }: { data: any[] }) => {
+  const chartData = data.map(item => ({
+    name: item.category,
+    value: item.count,
+    color: getCategoryColorRgbString(item.category)
+  }));
+  
+  // 使用chartData绘制图表
+  return <Chart data={chartData} />;
+};
+```
+
+## 5. 开发规范
+
+### 5.1 强制使用规则
+
+1. **所有涉及题目类别颜色显示的功能必须使用本统一颜色系统**，禁止直接使用硬编码颜色值。
+
+2. **优先使用预定义的类别颜色**，对于新增的临时类别，系统会自动分配备用颜色。
+
+3. **颜色值获取必须通过API接口**，禁止直接访问 `categoryColors` 对象。
+
+4. **保持颜色一致性**，同一类别在不同场景下必须使用相同的颜色。
+
+5. **确保可访问性**，所有颜色必须符合WCAG AA标准，优先考虑WCAG AAA标准。
+
+### 5.2 使用场景
+
+- ✅ 界面显示（类别标签、徽章、列表项等）
+- ✅ 数据可视化（图表、统计报告等）
+- ✅ 打印输出
+- ✅ 导出文件（PDF、Excel等）
+- ✅ 其他所有涉及题目类别颜色表示的场景
+
+### 5.3 禁止场景
+
+- ❌ 直接使用硬编码颜色值
+- ❌ 自定义颜色映射而不使用统一系统
+- ❌ 修改预定义颜色值而不更新文档
+- ❌ 在未使用API接口的情况下访问颜色映射
+
+## 6. 扩展说明
+
+### 6.1 添加新类别颜色
+
+当需要为新类别添加固定颜色时，应遵循以下步骤：
+
+1. 在 `categoryColors.ts` 文件中添加新的颜色映射
+2. 确保新颜色符合WCAG对比度标准
+3. 更新 `categoryColors.md` 文档中的颜色映射表
+4. 运行测试确保系统正常工作
+
+### 6.2 更新现有颜色
+
+如需更新现有类别的颜色，应遵循以下步骤：
+
+1. 确保新颜色符合WCAG对比度标准
+2. 在 `categoryColors.ts` 文件中更新颜色映射
+3. 更新 `categoryColors.md` 文档中的颜色映射表
+4. 检查所有使用该颜色的组件和功能，确保更新不会导致视觉问题
+5. 运行测试确保系统正常工作
+
+### 6.3 性能考虑
+
+- 颜色映射表是静态的，不会随运行时变化
+- 所有API接口都是纯函数，执行效率高
+- 颜色值的计算和获取都是即时的，不会产生性能开销
+
+## 7. 可访问性说明
+
+- 所有预定义颜色都符合WCAG AA标准（对比度比值 ≥ 4.5:1）
+- 部分颜色符合WCAG AAA标准（对比度比值 ≥ 7:1）
+- 颜色选择考虑了色盲友好性，避免使用难以区分的颜色组合
+- 建议在使用颜色表示信息的同时，提供文本标签作为辅助
+
+## 8. 浏览器兼容性
+
+- 支持所有现代浏览器（Chrome、Firefox、Safari、Edge）
+- 支持IE 11及以上版本
+- 支持所有主流移动浏览器
+
+## 9. 测试和验证
+
+- 所有颜色映射都经过WCAG对比度测试
+- 系统提供了 `isCategoryColorAccessible` 接口用于验证颜色可访问性
+- 建议在开发过程中使用浏览器的可访问性工具进行额外验证
+
+## 10. 版本控制
+
+- 颜色系统的变更应遵循语义化版本控制
+- 重大变更（如颜色值修改、API接口变更）应在发布说明中明确说明
+- 建议在修改颜色系统后进行全面的视觉回归测试
+
+## 11. 联系方式

+## 测试范围
+- 用户端：`/`、`/subjects`、`/tasks`、`/quiz`、`/result/:id`
+- 管理端：`/admin/login`、`/admin/dashboard`、`/admin/questions`、`/admin/categories`、`/admin/subjects`、`/admin/tasks`、`/admin/users`（含用户组管理）、`/admin/statistics`、`/admin/backup`、`/admin/config`
+- 说明：用户组功能（用户组管理、成员关系、考试任务按组分派与混合选择）已实现但目前标记为“未测试”。
 
 ## 测试环境
 - 操作系统：Windows
-- 浏览器：Chrome/Edge/Firefox
-- 测试时间：2024年12月17日
+- 前端开发地址：`http://localhost:5173/`
+- 后端开发地址：`http://localhost:3001/api`
+- 测试时间：2025-12-22
 
-## 功能测试结果
+## 测试方法
+- 静态代码审查：对页面路由、接口调用、关键交互与边界条件进行逐页核对
+- 冒烟检查：启动开发服务后，验证前后端可启动、接口可访问（以实际执行记录为准）
 
-### ✅ 用户端功能测试
+## 结果概览
+- 管理端：页面路由与菜单整体完整，但存在少量可达性与安全性问题
+- 用户端：存在多处关键交互链路断裂风险（会导致“无法加载科目/任务/无法开始考试/考试页空白”）
+- 用户组：实现已落地但缺少覆盖性验证与审计日志能力，需单独做回归测试

+### P0：用户端关键流程可能不可用
+- 用户信息状态来源不一致：`HomePage` 使用 `UserContext` 写入 `localStorage(survey_user)`，但 `SubjectSelectionPage` 与 `UserTaskPage` 使用 `zustand` 的 `useUserStore` 且未从 `localStorage` 恢复，导致 `user?.id` 可能为空，后续生成试卷/拉取任务会失败（见 `src/pages/HomePage.tsx:18`、`src/stores/userStore.ts:16`、`src/pages/SubjectSelectionPage.tsx:38`、`src/pages/UserTaskPage.tsx:28`）。
+- API 响应对象使用方式不一致：`src/utils/request.ts` 的响应拦截器会直接返回 `{ success, data }`，但 `SubjectSelectionPage`、`UserTaskPage` 仍按 `axios` 原始响应访问 `response.data.success`，会导致列表不渲染（见 `src/utils/request.ts:14`、`src/pages/SubjectSelectionPage.tsx:55`、`src/pages/UserTaskPage.tsx:39`）。
+- 考试页初始化逻辑可能清空题目：`QuizPage` 在设置题目后调用 `clearQuiz()`，而 `clearQuiz()` 会清空 `questions`，可能导致考试页无题可答（见 `src/pages/QuizPage.tsx:51`、`src/contexts/QuizContext.tsx:38`）。
 
-#### 3. 界面与体验
-- [x] 响应式设计（移动端适配）
-- [x] 加载状态显示
-- [x] 错误处理与提示
-- [x] 页面导航流畅
+### P1：管理端配置入口可达性问题
+- 存在 `/admin/config` 路由，但侧边栏菜单未提供入口，用户只能手工输入 URL 访问（见 `src/App.tsx:58`、`src/layouts/AdminLayout.tsx:29`）。
 
-### ✅ 管理端功能测试
+### P1：鉴权/敏感信息呈现风险（影响上线）
+- `adminAuth` 为简化放行逻辑，接口层面的“权限控制”在生产环境不成立（见 `api/middlewares/index.ts` 中 `adminAuth` 实现）。
+- 用户密码存在明文存储/展示路径（例如用户管理页面有显示/隐藏密码的 UI），属于上线前必须整改的安全项（见 `src/pages/admin/UserManagePage.tsx:36`）。
 
-#### 1. 管理员登录
-- [x] 用户名密码验证
-- [x] 登录状态保持
-- [x] 权限控制
+### P2：一致性与可维护性问题（影响后续扩展）
+- 同一功能域存在两套请求封装（`src/services/api.ts` 与 `src/utils/request.ts`）且返回值约定不同，容易造成新页面复用错误（已在用户端出现）。
+- 测试脚本与端口配置不一致：`test/*.js` 默认指向 `http://localhost:3000/api`，与当前后端默认端口 `3001` 不一致，直接运行会误判失败（见 `test/test_openspec_features.js:3`）。
 
-#### 2. 题库管理
-- [x] Excel文件导入
-- [x] 题目增删改查
-- [x] 题型筛选
-- [x] 数据验证
+## 建议完善（按收益排序）
+- 统一用户态管理：用户端统一使用 `UserContext` 或统一使用 `zustand`，并保证从 `localStorage` 恢复与退出清理一致。
+- 统一请求封装与返回类型：优先减少到一个请求层（或保证两者对外返回形态一致），避免页面端误用。
+- 修复考试页初始化顺序：确保“清理旧状态”发生在“写入新题目”之前，或仅清理 `answers` 不清理 `questions`。
+- 管理端补齐菜单入口：为 `/admin/config` 提供侧边栏入口，避免功能“存在但不可见”。
+- 用户组做专项回归：覆盖“全体用户”系统组约束、成员增删、任务按组分派、混合选择去重、报表导出。
