fix(测试数据生成器): 修复规则覆盖保存误创建重复规则

覆盖同名规则时 handleSave(true) 未传入已有规则 id，save() 走新建分支
导致旧规则保留且产生同名重复项，getByName 仍返回旧数据。

-## 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 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`

-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`）。

+
+## 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                                              |
+

+  // 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

+#### 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。
+
+---
+
+## 实施顺序
+
+```mermaid
+flowchart TD
+  A[1.1 transaction.oncomplete] --> B[1.2 delete settle 防竞态]
+  B --> C[2.4 补多 DB 测试]
+  C --> D[2.1 部分成功 count]
+  D --> E[2.2 统一 executeInTab]
+  E --> F[2.3 错误分隔符]
+  F --> G[3.x 可选重构]
+```
+
+| 阶段    | 预估工作量 | 风险             |
+| ------- | ---------- | ---------------- |
+| Phase 1 | 0.5~1 天   | 低，逻辑局部     |
+| Phase 2 | 0.5~1 天   | 中，涉及类型扩展 |
+| Phase 3 | 1~2 天     | 低，可延后       |

+| ---- | ------------------------------------------------------------------------------ |
+| A-1  | 全部单元测试通过，新增测试 ≥ 3（transaction 顺序、late onsuccess、多 DB 混合） |
+| A-2  | `tsc --noEmit` 无错误；若扩展 `StorageCleanResult`，所有引用处类型正确         |
+| A-3  | ESLint `--max-warnings=0` 通过                                                 |

+| B-2  | 单 DB，`deleteDatabase` blocked，fallback clear 成功 | `success: true, count: 1`；transaction 在 `oncomplete` 后 `db.close`          |

+| B-7  | localStorage 成功 + cookies 失败                     | `overallSuccess: false`，`result.error` 为 `Cookies: ...`（换行分隔多项失败） |

+| ---- | ------------------------------------------------------------------ |
+| E-1  | 注入脚本内无重复 `settled` / timeout 逻辑（删除与 clear 各自封装） |
+| E-2  | 错误文案仍为中文，含库名/store 名                                  |
+| E-3  | 无 `any`（测试文件除外）                                           |
+| E-4  | Phase 1 合并后，P1 项在 PR 描述中标注「已修复」并附测试名          |
+
+---
+
+## PR 检查清单
+
+```markdown
+## 修复内容
+
+- [ ] P1: transaction.oncomplete 后再 db.close
+- [ ] P1: deleteDatabase settle 防竞态
+- [ ] P2: 部分成功保留 count（可选）
+- [ ] P2: 多 DB 混合测试
+- [ ] P2: 错误信息 `\n` 分隔（可选）
+
+## 验收
+
+- [ ] npm run test / typecheck / lint 通过
+- [ ] 新增测试覆盖 B-2、B-3、B-5
+- [ ] 手动 D-1 ~ D-4 至少测 D-1、D-3
+```
+
+---
+
+## 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。

+import { getGeneratorById, searchGenerators } from '@/lib/generators';
+
+const generator = getGeneratorById('chineseName');
+const value = generator?.generate({});
+const matched = searchGenerators('uuid');
+```
+
+约束：
+
+- 新增生成器必须实现 `GeneratorDefinition`，并加入所属分类文件的导出列表。
+- 需要唯一值或大批量稳定输出时，优先实现 `generateAtIndex(params, index)`。
+- 新增分类时同步更新 `generatorCategories`，并确保 `GeneratorSelector` 能展示该分类。
