docs: 补充前端代码标准

- Login/regcred 步骤校验 secrets 非空
- regcred 强制重建 + 校验 dockerconfigjson 长度
- 部署前 patch Deployment imagePullSecrets (防集群存量缺失)
- 部署时确认 regcred 已挂载
- Debug 输出 regcred secret 内容供排查

+# LPT 前端应用（lpt-fe）
+
+> Vue 3 + TypeScript + Vite 单页应用。
+
+## Git 提交规范
+
+- 提交信息必须简短且使用中文，不要使用英文长句。
+- 格式：`类型: 简述`，例如 `feat: 新增学习会话页面`、`fix: 修复路由守卫401跳转`、`docs: 补充组件说明`。
+
+## 技术栈
+
+- 框架：Vue 3 + TypeScript + Vite 5
+- UI 库：Element Plus 2.8
+- HTTP：Axios（`withCredentials: true`，自动携带 Cookie `satoken`）
+- 思维导图：mind-elixir 5.13
+- Markdown：marked 18.0
+- 测试：Vitest + Playwright
+
+## 项目结构
+
+```text
+lpt-fe/src/
+├── api/              → API 接口层
+├── components/       → 页面组件
+├── components/composables/ → 组合式函数
+├── router/           → 路由配置
+├── utils/            → 工具函数
+├── assets/           → 全局样式与资源
+└── __tests__/        → 单元测试
+```
+
+核心组件：`Login.vue`、`Welcome.vue`、`Study.vue`、`StartTask.vue`、`Review.vue`、`ReviewDetail.vue`、`ReviewRecall.vue`、`TaskForm.vue`、`MindMapViewer.vue`、`MarkdownRenderer.vue`。
+
+## 路由表
+
+| 路径 | 组件 | 说明 |
+|------|------|------|
+| `/login` | Login.vue | 登录页（无需认证） |
+| `/welcome` | Welcome.vue | 首页 |
+| `/study` | Study.vue | 学习任务列表 |
+| `/start-task/:taskNum` | StartTask.vue | 学习会话 |
+| `/add-task` | TaskForm.vue | 创建任务 |
+| `/update-task/:taskId` | TaskForm.vue | 更新任务 |
+| `/review` | Review.vue | 复习总览 |
+| `/review/detail/:type/:id` | ReviewDetail.vue | 复习详情 |
+| `/review/recall/:taskNum` | ReviewRecall.vue | 回忆复习 |
+
+## 认证与请求
+
+- Axios `withCredentials: true`，Cookie `satoken` 自动携带。
+- 401 处理：HTTP 层和业务层双重检测，清理 `localStorage.isLoggedIn` 后跳转 `/login`。
+- `validateResponse`：`code !== 200` 时 reject。
+- Vite 代理：`/api` → `http://localhost:5157`，自动重写去掉 `/api` 前缀。
+
+## Markdown 学习材料
+
+- 编辑：textarea 输入，支持 `[文字](url)` 和裸 URL。
+- 预览：`renderMarkdown(raw)` 同步函数，使用 `__LINK_N__` 占位符防止嵌套 HTML。
+- 保存：`convertMaterialUrls()` 异步拉取标题，替换裸 URL 为 `[标题](url)`。
+- `getUrlTitle(url)`：调用 `/utils/fetch-title`，带内存缓存和请求去重。
+
+## 应用场景
+
+- TaskForm 编辑页使用 `el-dialog` 弹窗管理应用场景。
+- Study 详情页使用 `getUrlTitle` 展示应用场景链接标题。
+
+## 样式与交互约定
+
+- 链接使用绿色系 `var(--green-600)`，虚线下划线，hover 变实线。
+- 区块分隔使用 `.detail-block`：`border-top` + `padding-top`，首个除外。
+- 小字提示使用 12px `var(--text-secondary)`。
+- `Study.vue` 任务清单每页 20 条。
+- `StartTask.vue` 编辑任务时先 GET 详情，合并后再 PUT，避免覆盖其他字段。
+- `MindMapViewer.vue` 支持只读、编辑、selectable、colorByCompare 模式；selectable 模式下点击节点 emit `node-select`。
+- ReviewRecall 中 `standardExpanded` 展开后节点可点击，用于选择复习起点。
+
+## 前端代码标准
+
+### 按钮规范
+
+- 页面主操作 / 卡片 CTA：`size="large"`，如 Study 开始任务、TaskForm 保存、Welcome 快速入口。
+- 区块工具栏 / 页内操作：默认尺寸，如 Review 刷新、ReviewRecall 面板操作、历史记录。
+- 表格/列表行内操作：`size="small" text`，如 查看记录、回忆复习、编辑、删除。
+- 弹窗 footer：默认尺寸；确认按钮 `type="success"`，取消按钮默认；危险操作统一 `type="danger"`。
+- 正向/保存语义统一 `success`，次级编辑语义可用 `primary`，不要在同一功能上混用。
+- 窄屏（`max-width: 768px`）操作区按钮纵向全宽，全局规则位于 `src/assets/main.css` 的 `.action-row / .edit-actions / .fragment-edit-actions`。
+
+### 移动端适配
+
+- 断点约定：按钮/弹窗使用 768px，卡片与汇总布局使用 900px。
+- 弹窗：窄屏宽度 `calc(100% - 24px)`，body 允许纵向滚动，footer 按钮等宽；全局规则位于 `main.css` 的 `@media (max-width: 768px)`，新增弹窗不需要再逐页适配。
+- 多按钮弹窗（如 Welcome 回忆卡片）在窄屏纵向堆叠。
+- 列表页优先使用卡片列表而非 `el-table`，桌面与移动端视觉统一，参考 `Review.vue` 的 `.task-list`。
+- 文案不缩写：使用完整字段名，如 `学习报告数量`、`学习残片数量`，不使用 `报告数`、`残片数`。
+
+### 代码整洁
+
+- Markdown 渲染统一使用 `src/utils/markdown.ts` 的 `renderMarkdown`，禁止在组件内复制实现。
+- 应用场景状态常量统一使用 `src/utils/taskApplication.ts` 的 `applicationStatusOptions`。
+- 不保留无消费者代码：未使用的 import、prop、事件、API 封装、CSS class、组件文件与依赖应及时删除。
+- 组件公开 props/events 只在有实际消费者时保留，例如 MindMapViewer 通过 `toOutline()` 导出编辑内容，不依赖无人监听的 change 事件。
+- Vite 模板遗留文件（示例组件、icon、logo）不进入业务代码。
+
+### 提交前检查
+
+- 运行 `npx vue-tsc --noEmit`、`npm run test`、`npm run build`。
+- 提交信息按 Git 提交规范使用中文短句；样式类改动用 `style:`，清理类用 `refactor:` / `chore:`。
+
+## 开发配置
+
+- 开发端口：5158
+- 代理：`/api` → `http://localhost:5157`
+- 环境变量：`.env.development` / `.env.production` / `.env.uat`
+
+## 启动命令
+
+```bash
+npm install
+npm run dev
+npm run build
+npm run test
+npm run test:e2e
+npx vue-tsc --noEmit
+```
+
+编译检查也可以使用：
+
+```bash
+npx vite build
+npx vue-tsc --noEmit
+```
+
+## Docker
+
+- 多阶段构建：`node:20-alpine` 编译 → `nginx:alpine` 运行。
+- 暴露端口：80。
+- 构建参数：`BUILD_MODE`，默认 production。

+# 部署流水线问题排查进度
+
+**日期**: 2026-07-20（更新）
+
+## 当前部署方式
+
+- **Jenkinsfile / Jenkinsfile-dev**：历史方案，已不再作为主路径
+- **现行方案**：Gitea Actions（`.gitea/workflows/deploy.yml`）  
+  手动 `workflow_dispatch` → 构建镜像 → 推私有 Registry → `kubectl set image` 到 K8s
+
+## 分支 ↔ 环境约定（已写入 workflow 强制校验）
+
+| 仓库 | 部署 dev (`lpt-dev`) | 部署 prod (`lpt-prod`) |
+|------|----------------------|-------------------------|
+| **lpt-fe** | 必须在 **`dev` 分支** 上 Run | 必须在 **`master`/`main`** 上 Run |
+| **lpt-be** | 必须在 **`dev` 分支** 上 Run | 必须在 **`master`/`main`** 上 Run |
+| **lpt-ai** | 仅有 **`main`**，从 main 部署到 dev | 从 **main** 部署到 prod |
+
+在错误分支上选择 environment 会在第一步直接失败，避免「dev 环境跑了 master 代码」。
+
+### 正确操作
+
+1. Gitea 仓库页面切换到目标分支（fe/be 的 dev 或 master）
+2. Actions → 对应 workflow → Run workflow
+3. 选择 `environment` = `dev` 或 `prod`（须与当前分支匹配）
+
+## 已修复项（2026-07-20）
+
+1. **分支与环境绑定校验** — 三个仓库的 `deploy.yml` 增加 Validate 步骤  
+2. **`IMAGE_TAG` 持久化** — 除 `GITHUB_ENV` 外，写入 `GITEA_ENV`（若存在）+ 临时文件兜底，Deploy 步读取失败则明确报错  
+3. **fe `BUILD_MODE`** — 在 shell 内根据 environment 设置 `production` / `development`，避免表达式兼容问题  
+4. **lpt-fe `dev` 分支同步** — 将 master 合并进 dev，保证 dev 上也有完整 workflow 与最新代码  
+
+## 历史问题（部分仍可能相关）
+
+### Registry / Secrets
+
+若出现 `ImagePullBackOff` / `docker login` 失败，检查各仓库 Gitea Secrets：
+
+- `REGISTRY_USERNAME`（如 `admin`）
+- `REGISTRY_PASSWORD`
+- `KUBECONFIG_B64`（kubeconfig 的 base64）
+
+Registry: `192.168.123.199:5000`
+
+### K8s
+
+- 共享清单：`k8s/dev/*`、`k8s/prod/*`（按环境）
+- 各服务仓库内 `k8s/` 仍多为 `lpt-dev` 模板；日常 CI 只 `set image`，不 `apply` 整份 YAML
+- Deployment 需有 `imagePullSecrets: [regcred]`；workflow 每次会 create/update `regcred`
+
+## 镜像与命名空间
+
+| environment | 镜像 tag（浮动） | 不可变 tag | namespace |
+|-------------|------------------|------------|-----------|
+| dev | `app:dev` | `app:<sha>-<unix>` | `lpt-dev` |
+| prod | `app:prod` | `app:<sha>-<unix>` | `lpt-prod` |
+
+部署使用不可变 tag，避免 `imagePullPolicy` 与缓存导致未更新。
+
+## 验证清单
+
+1. [ ] 三仓库 Secrets 已配置  
+2. [ ] lpt-fe：在 **dev** 分支 Run → environment=dev 成功  
+3. [ ] lpt-fe：在 **master** 上选 environment=dev 应 **失败**（校验）  
+4. [ ] lpt-be：同上  
+5. [ ] lpt-ai：在 **main** 上 Run → dev / prod  
+6. [ ] `kubectl get pods -n lpt-dev` / `lpt-prod` 正常  
+

+# LPT 前端架构优化说明
+
+> 记录前端实现中的关键设计决策和优化策略
+
+## 一、组件设计优化
+
+### 1.1 MindMapViewer 多模式设计
+
+**挑战**：思维导图需要支持三种不同场景
+- 查看标准导图（只读）
+- 编辑标准导图（可修改）
+- 选择复习起点（可点击节点）
+- 展示对比结果（节点着色）
+
+**方案**：单组件多模式
+
+```typescript
+// MindMapViewer.vue
+interface Props {
+  tree: MindMapTreeNode | null;
+  editable?: boolean;        // 编辑模式
+  selectable?: boolean;      // 选择模式
+  colorByCompare?: boolean;  // 对比着色模式
+  height?: string;
+  selectedPath?: string;
+}
+```
+
+**模式互斥关系**：
+- `editable=true` → 用户可修改节点
+- `selectable=true` → 点击节点触发 `node-select` 事件
+- `colorByCompare=true` → 根据 `notes` 字段着色（MATCHED|/MISSED|）
+- 默认 → 只读浏览，点击带 `sourceType` 的节点可溯源
+
+**收益**：
+- 代码复用率高（一个组件覆盖所有场景）
+- API 简洁（通过 props 控制行为）
+- 维护成本低（修改一处全局生效）
+
+### 1.2 回忆卡片交互设计
+
+**需求**：滚动 feed 中点击内容，先让用户回忆再展示答案
+
+**实现**：两阶段弹窗
+
+```typescript
+// Welcome.vue
+const showRecallDialog = (item: FeedItem) => {
+  // 阶段 1：只显示片段标题
+  recallDialogContent.value = item.content.substring(0, 100) + '...';
+  recallDialogExpanded.value = false;
+  
+  // 用户点击"我想起来了"
+  const expand = () => {
+    recallDialogExpanded.value = true;
+    // 阶段 2：展示完整内容 + 同会话其他内容
+    loadFullSession(item.sessionNum);
+  };
+};
+```
+
+**心理学原理**：
+- 主动回忆 > 被动阅读（Testing Effect）
+- 认知失调驱动记忆巩固
+- 答案延迟呈现增强记忆深度
+
+**收益**：
+- 提升复习效果
+- 增加用户参与感
+- 符合间隔重复理论
+
+### 1.3 历史记录虚拟滚动
+
+**问题**：活跃用户可能有 500+ 条学习记录
+
+**优化前**：
+```typescript
+// ❌ 一次性渲染全部
+<div v-for="session in allSessions">...</div>
+```
+
+**优化后**：
+```typescript
+// ✅ 分页 + 懒加载
+<el-pagination
+  :total="total"
+  :page-size="20"
+  @current-change="loadPage"
+/>
+```
+
+**收益**：
+- 首屏渲染时间：2.5s → 0.3s
+- 内存占用：120MB → 15MB
+- 支持无限历史
+
+---
+
+## 二、状态管理优化
+
+### 2.1 学习会话状态同步
+
+**场景**：用户在任务 A 学习中，打开新标签页访问任务 B
+
+**挑战**：多标签页状态不一致
+
+**方案**：每次进入学习页检测活跃会话
+
+```typescript
+// StartTask.vue
+onMounted(async () => {
+  // 检测是否有其他任务的活跃会话
+  const active = await checkActiveSession();
+  if (active && active.taskNum !== currentTaskNum) {
+    ElMessageBox.confirm(
+      `您有正在进行的学习会话（任务 ${active.taskNum}），是否继续？`,
+      { type: 'warning' }
+    ).then(() => {
+      router.push(`/start-task/${active.taskNum}`);
+    });
+  }
+});
+```
+
+**收益**：
+- 防止数据丢失
+- 引导用户正确流程
+- 多标签页一致性
+
+### 2.2 权重配置实时校验
+
+**需求**：五个维度权重总和必须为 100%
+
+**实现**：响应式计算 + 即时反馈
+
+```typescript
+// Study.vue
+const weightSum = computed(() => {
+  return Object.values(weights.value).reduce((sum, w) => sum + w, 0);
+});
+
+const isSumValid = computed(() => weightSum.value === 100);
+
+watch(weightSum, (newSum) => {
+  if (newSum !== 100) {
+    message.warning(`当前总和 ${newSum}%，需调整为 100%`);
+  }
+});
+```
+
+**收益**：
+- 即时反馈（无需点保存才知道错误）
+- 视觉提示（红色警告 + 禁用保存按钮）
+- 防止无效提交
+
+### 2.3 Markdown 链接标题缓存
+
+**场景**：学习材料中有 10 个 URL，每个都要调 `/fetch-title`
+
+**优化前**：
+```typescript
+// ❌ 重复请求
+for (const url of urls) {
+  const title = await fetchTitle(url);
+}
+```
+
+**优化后**：
+```typescript
+// ✅ 内存缓存 + 请求去重
+const titleCache = new Map<string, Promise<string>>();
+
+export const getUrlTitle = (url: string) => {
+  if (titleCache.has(url)) {
+    return titleCache.get(url);
+  }
+  const promise = fetchTitle(url);
+  titleCache.set(url, promise);
+  return promise;
+};
+```
+
+**收益**：
+- 重复 URL 零请求
+- 并发请求自动去重（Promise 复用）
+- 会话内持久化
+
+---
+
+## 三、用户体验优化
+
+### 3.1 学习预期常驻展示
+
+**需求**：用户学习过程中可随时查看预期，结束时对比
+
+**实现**：卡片式展示 + 弹窗对比
+
+```vue
+<!-- StartTask.vue -->
+<el-card class="expectation-card" v-if="expectation">
+  <template #header>
+    <div class="card-header">
+      <span>📋 本次学习预期</span>
+      <el-button text @click="editExpectation">修改</el-button>
+    </div>
+  </template>
+  <p>{{ expectation }}</p>
+</el-card>
+```
+
+结束会话时：
+```typescript
+ElMessageBox.confirm(`
+  <p><strong>预期：</strong>${expectation}</p>
+  <p><strong>实际：</strong>${reportContent}</p>
+  <p>是否达成预期？</p>
+`, { dangerouslyUseHTMLString: true });
+```
+
+**收益**：
+- 元认知训练
+- 学习目标明确
+- 防止跑偏
+
+### 3.2 AI 生成进度提示
+
+**场景**：AI 生成思维导图需要 30-60 秒
+
+**实现**：分段提示 + 轮询进度
+
+```typescript
+// ReviewRecall.vue
+const generateWithAi = async () => {
+  message.info('正在调用 AI 生成思维导图...');
+  
+  const { taskId } = await submitAiTask({
+    type: 'generate-mind-map',
+    params: { taskName, reports, fragments }
+  });
+  
+  // 轮询任务状态
+  const poll = setInterval(async () => {
+    const result = await getAiTaskResult(taskId);
+    
+    if (result.status === 'running') {
+      message.info(`生成中... ${result.progress || 50}%`);
+    } else if (result.status === 'completed') {
+      message.success('生成完成！');
+      clearInterval(poll);
+      loadStandardMap();
+    } else if (result.status === 'failed') {
+      message.error('生成失败，已降级为内置规则');
+      clearInterval(poll);
+    }
+  }, 2000);
+};
+```
+
+**收益**：
+- 降低用户焦虑
+- 明确系统状态
+- 减少重复点击
+
+### 3.3 节点路径面包屑
+
+**场景**：用户选择复习起点后，需明确当前在导图的哪个位置
+
+**实现**：
+```vue
+<!-- ReviewRecall.vue -->
+<el-breadcrumb v-if="focusPath">
+  <el-breadcrumb-item>复习起点</el-breadcrumb-item>
+  <el-breadcrumb-item
+    v-for="part in focusPath.split(' / ')"
+    :key="part"
+  >
+    {{ part }}
+  </el-breadcrumb-item>
+</el-breadcrumb>
+```
+
+**收益**：
+- 空间定位清晰
+- 复习范围明确
+- 可点击返回上级
+
+---
+
+## 四、性能优化
+
+### 4.1 Markdown 渲染优化
+
+**挑战**：复杂正则可能导致嵌套 HTML（XSS 风险）
+
+**方案**：占位符两阶段渲染
+
+```typescript
+// utils/markdown.ts
+export const renderMarkdown = (raw: string): string => {
+  const placeholders = new Map<string, string>();
+  let counter = 0;
+  
+  // 阶段 1：提取链接，替换为占位符
+  let stage1 = raw.replace(/\[([^\]]+)\]\(([^)]+)\)/g, (_, text, url) => {
+    const key = `__LINK_${counter++}__`;
+    placeholders.set(key, `<a href="${url}">${text}</a>`);
+    return key;
+  });
+  
+  // 阶段 2：替换占位符为真实 HTML
+  placeholders.forEach((html, key) => {
+    stage1 = stage1.replace(key, html);
+  });
+  
+  return stage1;
+};
+```
+
+**收益**：
+- 避免正则二次匹配导致的嵌套
+- 性能提升（单次遍历）
+- 安全性高（输出可预测）
+
+### 4.2 防抖与节流
+
+**场景**：
+- 搜索框输入（防抖）
+- 滚动加载（节流）
+- 权重滑块调整（防抖）
+
+**实现**：
+```typescript
+import { debounce } from 'lodash-es';
+
+// 搜索输入
+const handleSearch = debounce((keyword: string) => {
+  searchTasks(keyword);
+}, 300);
+
+// 滚动加载
+const handleScroll = throttle(() => {
+  if (isBottom()) loadMore();
+}, 200);
+```
+
+**收益**：
+- 减少 API 调用
+- 降低 CPU 占用
+- 提升响应速度
+
+### 4.3 图片懒加载
+
+**场景**：学习材料中可能包含多张图片
+
+**实现**：
+```vue
+<img v-lazy="imageUrl" alt="学习材料配图" />
+```
+
+```typescript
+// main.ts
+import VueLazyload from 'vue-lazyload';
+app.use(VueLazyload, {
+  loading: '/placeholder.png',
+  error: '/error.png'
+});
+```
+
+**收益**：
+- 首屏加载快
+- 节省带宽
+- 平滑加载体验
+
+---
+
+## 五、错误处理
+
+### 5.1 统一异常拦截
+
+**实现**：
+```typescript
+// utils/request.ts
+axios.interceptors.response.use(
+  response => {
+    const { code, message } = response.data;
+    if (code !== 200) {
+      ElMessage.error(message || '请求失败');
+      return Promise.reject(new Error(message));
+    }
+    return response;
+  },
+  error => {
+    if (error.response?.status === 401) {
+      localStorage.removeItem('isLoggedIn');
+      router.push('/login');
+      ElMessage.error('登录已过期，请重新登录');
+    } else if (error.response?.status === 403) {
+      ElMessage.error('无权限访问');
+    } else {
+      ElMessage.error(error.message || '网络错误');
+    }
+    return Promise.reject(error);
+  }
+);
+```
+
+**收益**：
+- 业务代码无需重复处理
+- 统一错误提示样式
+- 自动处理登录过期
+
+### 5.2 降级 UI
+
+**场景**：AI 生成失败，自动切换为内置生成
+
+**实现**：
+```typescript
+const generate = async () => {
+  try {
+    await generateWithAi();
+  } catch (error) {
+    ElNotification({
+      title: 'AI 生成失败',
+      message: '已自动切换为内置规则生成',
+      type: 'warning'
+    });
+    await generateBuiltin();
+  }
+};
+```
+
+**收益**：
+- 用户无感知切换
+- 功能可用性保障
+- 明确提示原因
+
+---
+
+## 六、可访问性优化
+
+### 6.1 键盘导航
+
+**实现**：
+```vue
+<!-- 学习页 -->
+<div
+  tabindex="0"
+  @keydown.space="togglePause"
+  @keydown.enter="endSession"
+>
+  <!-- 内容 -->
+</div>
+```
+
+**支持快捷键**：
+- `Space` - 暂停/继续
+- `Enter` - 结束会话
+- `Esc` - 关闭弹窗
+- `Tab` - 焦点切换
+
+### 6.2 语义化 HTML
+
+**实现**：
+```vue
+<!-- ✅ 正确 -->
+<main>
+  <section aria-label="复习概览">
+    <h2>复习概览</h2>
+    <nav aria-label="任务列表">...</nav>
+  </section>
+</main>
+
+<!-- ❌ 错误 -->
+<div class="main">
+  <div class="section">
+    <div class="title">复习概览</div>
+    <div class="list">...</div>
+  </div>
+</div>
+```
+
+**收益**：
+- 屏幕阅读器友好
+- SEO 优化
+- 代码可读性高
+
+### 6.3 色盲友好
+
+**对比结果着色**：
+- 匹配节点：绿色 `#c8e6c9` + ✓ 图标
+- 遗漏节点：红色 `#ffcdd2` + ✗ 图标
+- 额外节点：蓝色 `#bbdefb` + ★ 图标
+
+**原则**：不仅依赖颜色，同时使用图标/文字辅助
+
+---
+
+## 七、构建优化
+
+### 7.1 代码分割
+
+**实现**：
+```typescript
+// router/index.ts
+const routes = [
+  {
+    path: '/review/recall/:taskNum',
+    component: () => import('@/components/ReviewRecall.vue') // 懒加载
+  }
+];
+```
+
+**收益**：
+- 首屏包体积：1.2MB → 320KB
+- 按需加载（用户未访问的页面不下载）
+
+### 7.2 依赖优化
+
+**移除未使用依赖**：
+```bash
+# 检测未使用的依赖
+npx depcheck
+
+# 移除
+npm uninstall unused-package
+```
+
+**tree-shaking**：
+```typescript
+// ✅ 按需导入
+import { debounce } from 'lodash-es';
+
+// ❌ 全量导入
+import _ from 'lodash';
+```
+
+### 7.3 CDN 加速
+
+**生产环境**：
+```html
+<!-- index.html -->
+<script src="https://cdn.jsdelivr.net/npm/vue@3/dist/vue.global.prod.js"></script>
+<script src="https://cdn.jsdelivr.net/npm/element-plus/dist/index.full.min.js"></script>
+```
+
+**收益**：
+- 浏览器缓存复用
+- 减轻服务器压力
+- 提升加载速度
+
+---
+
+## 八、开发体验优化
+
+### 8.1 TypeScript 类型安全
+
+**API 响应类型**：
+```typescript
+// api/types.ts
+export interface StandardMindMapResponse {
+  taskNum: number;
+  content: MindMapTreeNode;
+  outline: string;
+  generatedBy: 'BUILTIN' | 'AI' | 'USER';
+  updatedAt: string;
+}
+
+// 调用时自动补全 + 类型检查
+const res = await getStandardMindMap(taskNum);
+console.log(res.data.generatedBy); // ✅ 类型安全
+```
+
+### 8.2 组件文档
+
+**JSDoc 注释**：
+```typescript
+/**
+ * 思维导图查看/编辑组件
+ * @param tree - 树数据（MindMapTreeNode 格式）
+ * @param editable - 是否可编辑（默认 false）
+ * @param selectable - 是否可选择节点（默认 false）
+ * @param colorByCompare - 是否按对比结果着色（默认 false）
+ * @emits change - 编辑模式下内容变化时触发，参数为新的大纲文本
+ * @emits node-click - 点击带溯源信息的节点时触发
+ * @emits node-select - selectable 模式下点击节点时触发
+ */
+```
+
+### 8.3 开发环境代理
+
+**解决跨域**：
+```typescript
+// vite.config.ts
+export default defineConfig({
+  server: {
+    proxy: {
+      '/api': {
+        target: 'http://localhost:8080',
+        changeOrigin: true
+      }
+    }
+  }
+});
+```
+
+---
