-## 核心命令
-
-```bash
-npm run dev              # Chrome 开发模式（支持 HMR）
-npm run dev:firefox      # Firefox 开发模式
-npm run build            # Chrome 生产构建
-npm run build:firefox    # Firefox 生产构建
-npm run zip              # 打包 Chrome 扩展（.output/*.zip）
-npm run zip:firefox      # 打包 Firefox 扩展
-npm run lint             # ESLint 检查（--max-warnings=0）
-npm run typecheck        # TypeScript 类型检查（tsc --noEmit）
-npm run test             # 运行全部单元测试（vitest run）
-npm run test:watch       # Vitest 监视模式
-npm run test:coverage    # 带覆盖率的测试
-```
-
-运行单个测试文件：`npx vitest run path/to/file.test.ts`
-
-修改 `package.json` 后需运行 `npm install`（会自动触发 `postinstall` → `wxt prepare` 重新生成 `.wxt/` 类型声明）。
-
-## CI 流水线（GitHub Actions）
-
-严格顺序门控，任一步骤失败则终止：
-
-1. **setup** — 安装依赖，缓存 `node_modules`
-2. **lint**、**typecheck**、**test** — 三者并行运行，全部通过才继续
-3. **build** — Chrome + Firefox 矩阵构建（仅当步骤 2 全部通过时执行）
-
-Pre-commit 钩子（`.husky/pre-commit` → `lint-staged`）：
-
-1. 代码文件（`*.{ts,tsx,js,jsx,mjs}`）：运行 `eslint --fix --max-warnings=0`
-2. 同一代码文件：运行 `prettier --write`
-3. 其他文件（`*.{json,css,scss,md}`）：运行 `prettier --write`
-
-## 项目架构
-
-### 路由（不使用 React Router）
-
-路由完全通过 `config/features.tsx` 中的 `FEATURES` 数组管理。每个功能定义一个 `key`（类型为 `types/storage.d.ts` 中的 `PageType`）和三个懒加载组件，分别对应 `popup`、`sidepanel`、`tab` 三种渲染模式。`providers/RouterProvider.tsx` 中的 `RouterProvider` 根据存储状态渲染当前页面。
-
-存在三套独立的路由作用域：`app/popupRoute`、`app/sidepanelRoute`、`app/tabRoute`，各自维护独立的可见页面列表和页面排序。
-
-### 存储
-
-所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中声明，键名使用 kebab-case 格式（如 `app/currentRoute`）。使用 `utils/chromeStorage.ts` 中的类型安全封装（`storageUtil.get/set/remove`）。
-
-Router 同时使用 `chrome.storage.local` 持久化和 `localStorage` 快照来消除首屏闪烁。
-
-### 扩展通信
-
-使用 `@webext-core/messaging`。通信协议在 `utils/messages.ts` 中通过 `ProtocolMap` 定义。使用该模块导出的 `sendMessage` / `onMessage`，不要直接使用原生 `chrome.runtime.sendMessage`。
-
-### 页面组件模式
-
-功能页面遵循 **UI + Hook 分离** 模式，详见 [CODING_STANDARDS.md § 11](./CODING_STANDARDS.md#11-页面开发规范)：
-
-```
-pages/FeatureName/
-├── index.tsx              # UI 组件（纯展示，使用 shadcn/ui 组件）
-├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
-└── constants.ts           # 常量定义（可选）
-```
-
-- 页面组件调用 `useI18n('featureName')` 获取翻译函数
-- Hook 负责所有状态管理，通过返回值暴露给页面
-- 子组件可进一步拆分（如 `LiveClock.tsx`、`ResultView.tsx`）
-
-### 新功能开发清单
-
-1. 在 `types/storage.d.ts` 的 `PageType` 联合类型中添加新成员
-2. 在 `config/features.tsx` 的 `FEATURES` 数组中添加配置（key、翻译键、图标、三种渲染模式组件）
-3. 在 `pages/` 目录创建页面组件（懒加载）：
-   - `index.tsx` — 使用 `useLazyTranslation` 的 UI 组件
-   - `useFeatureName.ts` — 业务逻辑 Hook
-   - `constants.ts` — 常量（可选）
-4. 在 `i18n/locales/{zh,en}/features.json` 添加翻译（复杂功能可新建独立 JSON 文件）
-5. 如需新权限，更新 `wxt.config.ts` 的 `manifest.permissions`
-6. 添加对应的单元测试
-
-## 关键规范
-
-> 完整的代码编写规范详见 [CODING_STANDARDS.md](./CODING_STANDARDS.md)。
-
-### 浏览器 API
-
-始终使用 `wxt/browser` 导出的 `browser` 对象，而非原生 `chrome` API，以确保跨浏览器兼容性。
-
-### 路径别名
-
-`@/` 映射到项目根目录（已在 tsconfig 和 vitest.config 中配置）。跨目录导入使用 `@/` 绝对别名，同目录导入使用 `./` 相对路径。
-
-### UI 组件
-
-- 使用 `components/ui/` 下的 shadcn/ui 组件（button、dialog、select、input 等）
-- 图标：`lucide-react`
-- 样式：Tailwind CSS + `@/lib/utils` 中的 `cn()` 工具函数（clsx + tailwind-merge）
-- 主题：使用 shadcn/ui 语义化 token（`bg-background`、`text-foreground`、`border-border` 等），禁止硬编码颜色
-
-### 代码分割
-
-`wxt.config.ts` 通过 `manualChunksForHtmlOnly()` 自动分组 vendor 依赖（vendor-react、vendor-i18n、vendor-qr、vendor-dnd），无需手动配置。
-
-### 代码风格
-
-- 禁止使用 `any`（测试文件除外）
-- 未使用的变量/参数：使用 `_` 前缀（如 `_unused`）
-- Prettier：100 字符宽、单引号、尾逗号 all、LF 换行
-- ESLint 使用 `typescript-eslint` 的 `projectService: true`
-- 导出模式：页面组件 default export，工具函数/Hook 命名导出，UI 组件 forwardRef + 命名导出
-
-### 测试
-
-- 环境：jsdom
-- 全局变量：`vitest/globals`（describe、it、expect 等无需导入）
-- Setup 文件：`vitest.setup.ts` 自动 mock 以下内容：
-  - `chrome.*` / `browser.*` API（storage、tabs、runtime、cookies 等）
-  - `react-i18next`（返回 key 作为翻译）
-  - `@/utils/useLazyTranslation`（返回 `ns:key` 格式）
-  - `window.matchMedia`
-- 测试文件命名：`__tests__/*.test.{ts,tsx}` 或 `*.test.{ts,tsx}`
-- 使用 `vi.mock()` 进行模块级 mock；避免重复 mock `vitest.setup.ts` 中已有的内容
-- 测试工具：`@testing-library/react` + `@testing-library/user-event`
-
-### 国际化（i18n）
-
-- 命名空间：`common`（默认）、`features`
-- 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
-- 语言：`zh`（默认）、`en`
-- 翻译文件：`i18n/locales/{zh,en}/{common,features}.json` + 各功能独立 JSON 文件
-- 使用 `useLazyTranslation` Hook 加载功能专属翻译
-- 回退策略：缺失的翻译键回退到 `zh`，若仍缺失则返回占位格式 `namespace:key`
-
-### WXT 生成文件
-
-- `.wxt/` 目录由 `postinstall`（`wxt prepare`）自动生成，包含 TypeScript 类型声明和扩展 tsconfig
-- 生产构建输出到 `.output/` 目录
-- `tsconfig.json` 继承自 `./.wxt/tsconfig.json`

 ## 关键架构决策
 
 **路由**: 不使用 React Router。通过 `src/config/features.tsx` 的 `FEATURES` 数组管理，`RouterProvider` 根据 `PageType`
-渲染对应组件。支持三种渲染模式：popup（弹窗）、sidepanel（侧边栏）和 browser-tab（浏览器新标签页，通过 `open_in_tab` 打开）。
+渲染对应组件。支持三种渲染模式：popup（弹窗）、sidepanel（侧边栏）和 tab（浏览器新标签页，TopBar「在标签页打开」调用 `openExtensionPage('popup.html', { mode: 'tab' })`，由 `getEntryPointType()` 根据 URL 参数 `mode=tab` 识别）。
 每种模式有独立的路由和可见页面配置（`app/popupRoute`、`app/sidepanelRoute`、`app/tabRoute` 等）。
 
 **存储**: 所有 Chrome Storage 键必须在 `src/types/storage.d.ts` 的 `StorageSchema` 中定义，键名使用 kebab-case 格式（如 `app/currentRoute`）。
-使用 `src/utils/chromeStorage.ts` 及其 Hook。Router 同时使用 `chrome.storage.local` 和 `localStorage` 做快照以消除首屏闪烁。

+# Popup 布局重构 — 功能导航与 Dashboard 移除
+
+> 创建时间: 2026-07-05
+> 状态: 待实施
+> 关联模块: `src/entrypoints/popup/`、`src/layout/FeatureNav/`、`src/providers/RouterProvider.tsx`
+> 影响范围: 仅 popup 入口（tab / sidepanel 不在本次布局范围）
+
+## 背景与目标
+
+当前 popup 采用 **Dashboard 首页 + TopBar 搜索跳转** 模式：用户打开扩展后先看到仪表盘卡片网格，再点击进入具体工具。布局为固定 400×600（见 `src/entrypoints/popup/App.tsx` 与 `src/entrypoints/popup/index.html`），TopBar 在非 dashboard 页面显示「返回首页」按钮。
+
+该模式增加了一步选工具操作。本次重构将 popup 改为 **工具直达 + 右侧常驻导航**，并移除 Dashboard 页面。
+
+| 维度       | 现状                          | 目标                                      |
+| ---------- | ----------------------------- | ----------------------------------------- |
+| 默认页     | `dashboard`                   | 新用户默认 `timestamp`                    |
+| 导航       | Dashboard 卡片网格 + 搜索跳转 | 右侧常驻纯图标导航栏                      |
+| 首页       | Dashboard 独立页              | 移除                                      |
+| Popup 宽度 | 400px                         | 450px（内容区 ~402px + 导航栏 48px）      |
+| 作用范围   | —                             | 仅 popup 改布局；tab / sidepanel 不加导航 |

+| 总高度   | 600px  | 不变                                           |
+| 主内容列 | flex-1 | 约 402px，需 `min-w-0` 防止 flex 子项溢出      |
+| 导航栏   | 48px   | Tailwind `w-12`，固定宽度，不参与 flex 收缩    |
+
+### 视觉规范
+
+- 导航栏：左侧 `border-l border-border`，垂直排列图标按钮
+- 图标按钮：`h-9 w-9` 或 `h-10 w-10`，纯图标
+- Tooltip：使用原生 `title` 属性 + `aria-label={feature.label}`，不引入 Tooltip 组件
+- Active 态：背景 `bg-muted` + 左侧 `border-l-2 border-primary`
+- 导航列表超出高度时：`overflow-y-auto`（600px 高度下 9 个工具通常无需滚动）

+
+## FeatureNav 组件规格
+
+新建 `src/layout/FeatureNav/`，遵循 UI + Hook 分离模式（见 `.github/CODING_STANDARDS.md` §11）。
+
+### 文件结构
+
+```

+
+### resolveNavFeatures.ts
+
+从 `src/pages/Dashboard/dashboardFeatures.ts` 迁出并重命名：

+  key: PageType;
+  feature: FeatureConfig & { icon: NonNullable<FeatureConfig['icon']> };
+}
+
+export function resolveNavFeatures(keys: PageType[], visiblePages: PageType[]): NavFeatureItem[];
+```
+
+逻辑与旧 `resolveDashboardFeatures` 一致：
+
+- 按 `keys`（即 `pageOrder`）顺序遍历
+- 跳过不在 `visiblePages` 中的项
+- 跳过无 `icon` 的 feature（dashboard 移除后不应出现）
+
+### useFeatureNav.ts
+
+```typescript
+export interface UseFeatureNavReturn {
+  navItems: NavFeatureItem[];
+  currentPage: PageType;
+  navigateTo: (page: PageType) => void;
+}
+```
+
+- 从 `useRouter()` 读取 `currentPage`、`pageOrder`、`visiblePages`、`navigateTo`
+- 用 `useMemo` 调用 `resolveNavFeatures(pageOrder, visiblePages)` 生成 `navItems`
+
+### index.tsx
+
+- 渲染 `<nav aria-label="功能导航">` 包裹垂直按钮列表
+- 每项为 `<button type="button">`，内含 Lucide 图标
+- 点击调用 `navigateTo(item.key)`
+- 当前项添加 active 样式与 `aria-current="page"`
+
+### 引用范围
+
+**仅** `src/entrypoints/popup/App.tsx` 引用 `FeatureNav`。sidepanel / tab 入口不引入该组件。

+### 边界说明
+
+`recentlyUsedTools` 若含已移除的 `dashboard` 等非法项，当前 `isValidPageList` 校验要求数组**全部**合法，失败时整表回退为 `[]`。影响：TopBar 搜索历史中的「最近使用」可能被清空。此为已知低影响边界；实现时可选优化为「过滤非法项保留合法项」，**非必须**。

+
+## 实施顺序
+
+```
+1. 迁出 resolveNavFeatures + 新建 FeatureNav 组件与测试
+2. 修改 popup/App.tsx 布局 + popup/index.html 宽度
+3. 全局移除 dashboard（PageType → FEATURES → pageLoader → 删页面目录）
+4. 精简 TopBar / RouterProvider / RouterContainer / PageSkeleton
+5. 批量更新测试 → npm run typecheck && npm run test && npm run lint

+
+## 不在范围
+
+- tab / sidepanel 布局改造（不加 FeatureNav）
+- `visiblePages` / `pageOrder` 可视化配置 UI
+- Popup 高度变更（保持 600px）
+- 修改 `AGENTS.md` 中 spec 目录引用（实际 spec 位于 `docs/spec/`）
+
+---
+
+## PR 检查清单
+
+```markdown
+## 功能
+
+- [ ] 新建 FeatureNav 组件（index / useFeatureNav / resolveNavFeatures）
+- [ ] popup 布局改为双列（主内容 + 右侧导航）

+
+---
+
+## 风险与边界说明
+
+1. **Dashboard 移除为全局变更**：虽 FeatureNav 仅 popup 使用，但 `PageType` 删除 `dashboard` 会影响所有入口的类型校验与路由合法性。
+2. **老用户 dashboard 路由软迁移**：依赖 `isValidPage` 回退到 `defaultRoute`，不会 crash，但用户会察觉「首页消失、默认变为时间戳」——符合预期。
+3. **450px 宽度**：Chrome popup 允许扩展较默认更宽；若未来 Firefox 有差异需在 Firefox 构建中手动验证。
+4. **recentlyUsedTools 整表校验**：见「默认路由策略 → 边界说明」，可选后续优化。

+
+## 背景与目标
+
+本次修复针对 `storageCleaner.ts` 中 IndexedDB 清理逻辑及错误处理链路的审查结论，按优先级分三阶段实施。
+
+| 问题域              | 现状                                           | 目标                              |

+
+---
+
+## Phase 1 — 合并前必做（P1）
+
+### 1.1 等待 IndexedDB transaction 完成后再关闭连接
+
+#### 问题
+
+`clearObjectStores` 在 `Promise.all(clearStore...)` 结束后立刻 `db.close()`。单个 `clearReq.onsuccess` 只表示 request 完成，transaction 可能尚未 commit，存在清空被回滚的风险。
+
+#### 根因
+
+IndexedDB 规范中，transaction 的持久化以 `transaction.oncomplete` 为准，而非单个 request 的 `onsuccess`。
+
+#### 修复方案
+
+在注入脚本内的 `clearObjectStores` 中，增加 `waitForTransaction` 辅助函数：
+
+```typescript
+const waitForTransaction = (tx: IDBTransaction): Promise<void> =>
+  new Promise((resolve, reject) => {
+    tx.oncomplete = () => resolve();
+    tx.onerror = () => reject(tx.error ?? new Error('Transaction failed'));
+    tx.onabort = () => reject(tx.error ?? new Error('Transaction aborted'));
+  });
+```
+
+修改 `openReq.onsuccess` 分支：
+
+```typescript
+const transaction = db.transaction(storeNames, 'readwrite');
+const errors = (
+  await Promise.all(
+    storeNames.map((storeName) => clearStore(transaction.objectStore(storeName), storeName)),
+  )
+).filter((error): error is string => Boolean(error));
+
+try {
+  await waitForTransaction(transaction);
+} catch {
+  db.close();
+  resolve({
+    success: false,
+    errors: [`清空 IndexedDB 失败（${dbName}），请刷新后重试`],
+  });
+  return;
+}
+
+db.close();
+resolve({ success: errors.length === 0, errors });
+```
+
+#### 涉及文件
+
+- `src/utils/storageCleaner.ts` — `injectClearIndexedDB` 内 `clearObjectStores`
+
+#### 新增测试
+
+```typescript
+it('should wait for transaction complete before closing db', async () => {
+  // mock: clear onsuccess 先于 transaction.oncomplete 触发
+  // 断言 db.close 在 transaction.oncomplete 之后调用
+});
+```
+
+---
+
+### 1.2 消除 deleteDatabase 超时竞态
+
+#### 问题
+
+超时 `resolve('timeout')` 后，`deleteReq.onsuccess` 仍可能触发；此时 fallback 的 `indexedDB.open` 与进行中的 `deleteDatabase` 可能并发，行为未定义。
+
+#### 修复方案
+
+为每个 DB 删除引入 **单次 settle** 状态：
+
+```typescript
+const waitForDeleteDatabase = (dbName: string, timeoutMs: number) =>
+  new Promise<'deleted' | 'blocked' | 'timeout' | 'error'>((resolve) => {
+    let settled = false;
+    const settle = (status: 'deleted' | 'blocked' | 'timeout' | 'error') => {
+      if (settled) return;
+      settled = true;
+      clearTimeout(timeout);
+      resolve(status);
+    };
+
+    const deleteReq = indexedDB.deleteDatabase(dbName);
+    const timeout = setTimeout(() => {
+      console.warn('IndexedDB delete timeout:', dbName);
+      settle('timeout');
+    }, timeoutMs);
+
+    deleteReq.onblocked = () => {
+      console.warn('IndexedDB delete blocked:', dbName);
+      settle('blocked');
+    };
+    deleteReq.onsuccess = () => settle('deleted');
+    deleteReq.onerror = () => settle('error');
+  });
+```
+
+#### timeout / blocked 后的 fallback 策略
+
+| 状态      | 行为                                                               |
+| --------- | ------------------------------------------------------------------ |
+| `blocked` | 立即 fallback `clearObjectStores`（页面仍占用连接，open 通常可行） |
+| `timeout` | 先 `await delay(100~200ms)` 再 fallback，降低与 delete 并发概率    |
+| `error`   | 不 fallback，直接报错                                              |
+
+#### 涉及文件
+
+- `src/utils/storageCleaner.ts` — 替换现有 `new Promise` 删除逻辑
+
+#### 新增测试
+
+```typescript
+it('should ignore late onsuccess after delete timeout', async () => {
+  // deleteBehavior: timeout，5000ms 后 resolve timeout
+  // 6000ms 后再触发 onsuccess
+  // 断言：只走 fallback 一次，count 不因 late onsuccess 重复 +1
+});
+```
+
+---
+
+## Phase 2 — 建议同 PR 或紧接 follow-up（P2）
+
+### 2.1 IndexedDB 部分成功时保留 count
+
+#### 问题
+
+多 DB 场景返回 `{ count: 2, errors: ['...'] }` 时，`runCleanScript` 只返回 `{ success: false, error }`，用户看不到已清理 2 个库。
+
+#### 修复方案（推荐）
+
+扩展失败分支类型，可选 `count`：
+
+```typescript
+// src/types/storage.d.ts
+export type StorageCleanResult =
+  | { success: true; count: number }
+  | { success: false; error: string; count?: number }; // 部分成功时的已清理数
+```
+
+修改 `runCleanScript`：
+
+```typescript
+if (raw.errors?.length) {
+  const errorMsg = raw.errors.join('\n');
+  const partialHint = raw.count > 0 ? `（已成功清理 ${raw.count} 个数据库，但部分失败）\n` : '';
+  return {
+    success: false,
+    error: partialHint + errorMsg,
+    ...(raw.count > 0 ? { count: raw.count } : {}),
+  };
+}
+```
+
+#### UI 层（可选增强）
+
+`CleaningResult.tsx` 失败时若 `result.indexedDB?.count` 存在，可展示部分成功提示（非必须，error 字符串已含 hint 即可）。
+
+#### 涉及文件
+
+- `src/types/storage.d.ts`
+- `src/utils/storageCleaner.ts` — `runCleanScript`
+- `src/utils/__tests__/storageCleaner.test.ts`
+- （可选）`src/pages/StorageCleaner/components/CleaningResult.tsx`
+
+#### 新增测试
+
+```typescript
+it('should preserve partial count when some IndexedDB databases fail', async () => {
+  // 3 个 DB：2 成功删除，1 blocked 且 fallback 失败
+  // expect: success false, count 2, error 含「已成功清理 2 个」
+});
+```
+
+---
+
+### 2.2 统一 executeScript 调用入口
+
+#### 问题
+
+`runScript` 与 `runCleanScript` 各自调用 `browser.scripting.executeScript`，行为不一致（吞错 vs 抛错）。
+
+#### 修复方案
+
+抽取底层函数：
+
+```typescript
+type ExecuteScriptMode = 'fallback' | 'throw';
+
+async function executeInTab<T>(
+  tabId: number,
+  func: () => T | Promise<T>,
+  options: { errorLabel: string; mode: 'fallback'; fallback: T },
+): Promise<T>;
+async function executeInTab<T>(
+  tabId: number,
+  func: () => T | Promise<T>,
+  options: { errorLabel: string; mode: 'throw' },
+): Promise<T>;
+async function executeInTab<T>(...) {
+  try {
+    const [result] = await browser.scripting.executeScript({ target: { tabId }, func });
+    return (result?.result as T) ?? (options.mode === 'fallback' ? options.fallback : undefined as T);
+  } catch (error) {
+    console.error(`Failed to ${options.errorLabel}:`, error);
+    if (options.mode === 'throw') throw error;
+    return options.fallback;
+  }
+}
+```
+
+- `runScript` → `executeInTab(..., { mode: 'fallback', fallback })`
+- `runCleanScript` → `executeInTab(..., { mode: 'throw' })` + 结果解析
+
+#### 涉及文件
+
+- `src/utils/storageCleaner.ts`
+
+#### 验收
+
+现有 11 个测试全部通过，无行为回归。
+
+---
+
+### 2.3 错误信息分隔符统一
+
+#### 问题
+
+`runCleanScript` 用 `'; '` 拼接，`clearStorage` 的 `result.error` 用 `'\n'`，UI 用 `break-all` 展示，多错误时可读性不一致。
+
+#### 修复方案
+
+IndexedDB 内部多错误统一改为 `'\n'`：
+
+```typescript
+error: raw.errors.join('\n');
+```
+
+#### 涉及文件
+
+- `src/utils/storageCleaner.ts`
+- 相关测试断言（若有 `'; '` 期望）
+
+---
+
+### 2.4 补充多 DB 混合场景测试
+
+| 用例               | 输入                           | 期望                                         |
+| ------------------ | ------------------------------ | -------------------------------------------- |
+| 全部成功           | 3 DB，均 delete success        | `success: true, count: 3`                    |
+| 部分 fallback 成功 | 2 success + 1 blocked→clear OK | `success: true, count: 3`                    |
+| 部分失败           | 2 success + 1 error            | `success: false, count: 2, error 含失败库名` |
+| 空库列表           | `databases()` 返回 `[]`        | `success: true, count: 0`                    |
+
+#### 涉及文件
+
+- `src/utils/__tests__/storageCleaner.test.ts`
+- 扩展 `createIndexedDBMock` 支持 per-db 不同 `deleteBehavior`
+
+---
+
+## Phase 3 — 可选优化（P3）
+
+### 3.1 超时常量提升到模块级
+
+```typescript
+// src/utils/storageCleaner.ts 或 src/pages/StorageCleaner/constants.ts
+const INDEXED_DB_DELETE_TIMEOUT_MS = 5000;
+const INDEXED_DB_CLEAR_STORE_TIMEOUT_MS = 5000;
+```
+
+注入脚本通过闭包引用（executeScript 会序列化 func，常量需在 func 外部定义并 capture，或仍写在 func 内但从模块常量赋值）。
+
+### 3.2 IndexedDB 逻辑拆分（长期）
+
+将 `clearObjectStores`、`waitForDeleteDatabase` 等抽到 `src/utils/indexedDbCleaner.ts` 的纯函数，注入层只做：
+
+```typescript
+async () => clearAllIndexedDBs(INDEXED_DB_DELETE_TIMEOUT_MS);
+```
+
+便于单测，不依赖 `mockExecuteScriptEval` 间接执行注入函数。工作量大，建议单独 PR。

+## 风险与边界说明
+
+1. **fallback 清空 ≠ 删除库**：blocked 时只清 object store，库结构仍在；成功 `count` 表示「有效清理动作完成」，需在 UI/文档中说明（可选文案：「数据已清空，数据库结构可能仍存在」）。
+2. **timeout 延迟 fallback**：100~200ms 为经验值，无法完全消除竞态，只能降低概率；完全消除需浏览器不支持 abort delete 的前提下接受 best-effort。
+3. **类型扩展**：`StorageCleanResult` 加可选 `count` 为向后兼容；消费方用 `'count' in result && result.count` 判断即可。

+以下行为以 `src/` 源码为准；设计文档中的旧版 class API、`metadata`/`options` 嵌套结构已废弃。
+
+### Worker 任务 ID（`generationId`）
+
+`useGenerator` 每次调用 `generate()` 递增 `generationIdRef`，经 `start` 消息传入 Worker。Worker 所有响应（`progress` / `complete` / `error`）均携带同一 `generationId`。
+
+- **取消**：`cancel()` 先递增 ID 再发送 `cancel`，使进行中的 Worker 响应被主线程忽略；Worker 每生成 100 行让出事件循环以处理 cancel。
+- **快速重试**：新任务 ID 大于旧响应时，旧消息被丢弃，避免 UI 状态错乱。
+
+类型见 `WorkerRequestMessage` / `WorkerResponseMessage`（`src/types/testDataGenerator.ts`）。

+### 规则存储写入失败

+`ruleStorage.save()` / `update()` 在 `localStorage.setItem` 失败时返回 `null`（不部分提交）。页面层（如 `FieldList.tsx`）仅在返回值非空时 Toast 成功。详见 [rule-management.md § 存储机制](./rule-management.md#存储机制) 与 `src/utils/README.md`。

+  fields: FieldConfig[];

+  csvMode: boolean;
+}
+```
+
+### useGenerator Hook
+
+`src/pages/TestDataGenerator/hooks/useGenerator.ts` 负责 Worker 生命周期与 `generationId` 管理：
+
+- Worker **复用**：同一 Hook 实例内只创建一次，出错后 `terminate` 并在下次重建
+- **开始生成**：`generate(fields, count, csvMode?)` 递增 `generationId` 并 post `start`
+- **取消**：`cancel()` 递增 ID（使旧响应失效）并 post `cancel`；取消完成的 `complete` 不写入 `error` 状态
+- **响应过滤**：`onmessage` 中若 `data.generationId !== generationIdRef.current` 则忽略
+
+```typescript
+const generate = (fields: FieldConfig[], count: number, csvMode = false) => {
+  if (isGenerating) return;
+  const generationId = ++generationIdRef.current;
+  worker.postMessage({ type: 'start', payload: { generationId, fields, count, csvMode } });
+};
+
+const cancel = () => {
+  if (workerRef.current && isGenerating) {
+    ++generationIdRef.current;
+    worker.postMessage({ type: 'cancel' });
+    setIsGenerating(false);
+  }
+};
+```
+
+### Worker 实现要点
+
+`src/workers/generator.worker.ts`：
+
+- 按 `field.generatorId` 查找生成器；选填字段按 `nullRate` 随机置 `null`
+- 唯一性：≤1000 条随机+重试；>1000 条优先 `generateAtIndex`
+- 每 `YIELD_EVERY`（100）行 `await setTimeout(0)`，以便处理 `cancel`
+- 进度：每 1000 条或最后一行 post `progress`
