+# 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 |

+### 结构示意
+
+```mermaid
+flowchart LR
+  subgraph popup ["Popup 450x600"]
+    subgraph mainCol ["主列 flex-1"]
+      TopBar["TopBar"]
+      Content["RouterContainer"]

+### 尺寸约束
+
+| 属性     | 值     | 说明                                           |
+| -------- | ------ | ---------------------------------------------- |
+| 总宽度   | 450px  | `App.tsx` 容器 + `index.html` 内联样式同步修改 |
+| 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
+
+```
+src/layout/FeatureNav/
+├── index.tsx              # 垂直图标按钮列表、active 高亮、无障碍属性
+├── useFeatureNav.ts       # 读路由状态，暴露 navItems / navigateTo / currentPage
+├── resolveNavFeatures.ts  # 从 Dashboard 迁出的功能列表解析逻辑
+└── __tests__/
+    ├── index.test.tsx
+    └── resolveNavFeatures.test.ts
+```
+
+### resolveNavFeatures.ts
+
+从 `src/pages/Dashboard/dashboardFeatures.ts` 迁出并重命名：
+
+```typescript
+export interface NavFeatureItem {
+  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。
+
+---
+
+## popup/App.tsx 目标结构
+
+```tsx
+import RouterProvider from '@/providers/RouterProvider';
+import TopBar from '@/layout/TopBar';
+import FeatureNav from '@/layout/FeatureNav';
+import RouterContainer from '@/components/RouterContainer';
+import ErrorBoundary from '@/components/ErrorBoundary';
+
+export default function App() {
+  return (
+    <RouterProvider
+      defaultRoute="timestamp"
+      syncKey="app/popupRoute"
+      visiblePagesKey="app/popupVisiblePages"
+      pageOrderKey="app/popupPageOrder"
+    >
+      <div className="flex w-[450px] max-w-[450px] min-w-[450px] h-[600px] min-h-[600px] overflow-hidden bg-background">
+        <div className="flex flex-col flex-1 min-w-0">
+          <TopBar />
+          <ErrorBoundary>
+            <RouterContainer />
+          </ErrorBoundary>
+        </div>
+        <FeatureNav />
+      </div>
+    </RouterProvider>
+  );
+}
+```
+
+`src/entrypoints/popup/index.html` 内联样式中 `width: 400px` 改为 `width: 450px`。
+
+---
+
+## 移除 Dashboard（全局类型变更）
+
+布局仅改 popup，但 `dashboard` 从 `PageType` 移除会影响全项目类型与路由校验。
+
+### 删除文件
+
+| 路径                                  | 说明             |
+| ------------------------------------- | ---------------- |
+| `src/pages/Dashboard/`                | 整目录（含测试） |
+| `src/config/pageLoaders/dashboard.ts` | Dashboard 懒加载 |
+
+### 修改文件
+
+| 文件                                 | 改动                                                        |
+| ------------------------------------ | ----------------------------------------------------------- |
+| `src/types/storage.d.ts`             | 从 `PageType` 联合类型删除 `'dashboard'`                    |
+| `src/config/featureMeta.ts`          | 删除 dashboard 条目                                         |
+| `src/config/pageLoaders/index.ts`    | 删除 `case 'dashboard'`                                     |
+| `src/components/RouterContainer.tsx` | 去掉 dashboard 骨架屏分支；统一使用 `page-transition-enter` |
+| `src/components/PageSkeleton.tsx`    | 删除 `variant: 'dashboard'` 及对应 UI                       |
+| `src/styles/shell.css`               | 删除 `.page-transition-dashboard`                           |
+
+### TopBar 精简
+
+`src/layout/TopBar/index.tsx` 与 `useTopBar.ts`：
+
+- 删除「返回首页」按钮（`ArrowLeft` + `goHome`）
+- 删除 `isDashboard` 状态及相关导出
+- 搜索过滤中 `f.key === 'dashboard'` 的特殊排除逻辑可删除
+
+### RouterProvider 变更
+
+`src/providers/RouterProvider.tsx`：
+
+- 删除 `goHome()` 方法及 Context 中的 `goHome` 字段
+- 全局 `defaultRoute` 默认值由 `'dashboard'` 改为 `'timestamp'`
+- popup 显式传入 `defaultRoute="timestamp"`（与全局默认一致，便于阅读）
+
+### Sidepanel 最小修复
+
+`src/entrypoints/sidepanel/App.tsx` 若仍存在：
+
+- `defaultRoute="dashboard"` 改为 `defaultRoute="timestamp"`
+- 不添加 FeatureNav 布局
+
+---
+
+## 默认路由策略（仅新用户）
+
+利用现有 `RouterProvider` 机制，**无需额外迁移代码**。
+
+```typescript
+// 首屏（localStorage 快照，消除闪烁）
+const [currentPage] = useState(() => getSyncSnapshot(syncKey, defaultRoute, isValidPage));
+
+// 异步加载 chrome.storage
+const savedRoute = (stored[syncKey] ?? defaultRoute) as PageType;
+if (isValidPage(savedRoute) && syncRoute && !hasUserNavigatedRef.current) {
+  setCurrentPage(savedRoute);
+}
+```
+
+| 场景                                       | 行为                                                             |
+| ------------------------------------------ | ---------------------------------------------------------------- |
+| 新用户（无 `app/popupRoute`）              | 首屏 + 持久化均为 `timestamp`                                    |
+| 老用户（如 `app/popupRoute: 'jsonTools'`） | 恢复上次路由                                                     |
+| 老用户曾存 `dashboard`                     | `isValidPage('dashboard')` 为 false → 回退 `timestamp`（软迁移） |
+| 右键菜单 deep link                         | `?feature=&payload=` 优先级不变，高于默认路由                    |
+| 用户主动切换                               | `navigateTo` 后 `hasUserNavigatedRef` 阻止异步覆盖               |
+
+`visiblePages` / `pageOrder` 中残留的 `dashboard` 由 `mergeWithDefaults` 自动滤除（不在新默认列表中）。
+
+### 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）
+- [ ] popup 宽度 450px（App.tsx + index.html）
+- [ ] popup defaultRoute="timestamp"
+- [ ] 全局移除 dashboard（PageType、FEATURES、pageLoader、页面目录）
+- [ ] TopBar 移除返回按钮与 goHome 相关逻辑
+- [ ] RouterProvider 移除 goHome，defaultRoute 改为 timestamp
+- [ ] sidepanel defaultRoute 最小修复（若文件存在）
+
+## 测试
+
+- [ ] FeatureNav / resolveNavFeatures 单元测试
+- [ ] 更新 RouterProvider / TopBar / RouterContainer / features 测试
+- [ ] 删除 Dashboard 相关测试
+
+## 验收
+
+- [ ] npm run typecheck / test / lint 通过
+- [ ] 手动 A-1 ~ A-5、B-1 ~ B-4 通过
+```
+
+---
+
+## 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。

 ### 本地存储

-使用 localStorage 存储规则数据:
+使用 `localStorage`，键名 `testDataGenerator_rules`。API 为**命名导出函数**（见 `src/utils/ruleStorage.ts`）：
+
+| 函数 | 说明 |
+| ---- | ---- |
+| `getAll()` / `getById()` / `getByName()` | 读取 |
+| `save()` / `update()` / `deleteRule()` / `duplicate()` | 写入；失败时返回 `null` 或 `false` |
+| `recordUse()` | 递增 `useCount`、更新 `lastUsedAt` |
+| `search()` / `getRecent()` | 搜索与最近使用 |
+| `exportRules()` / `importRules()` | 导入导出 JSON 数组 |
+| `clear()` | 清空全部规则 |
+
+写入失败（如 `QuotaExceededError`）时，内部 `setAll()` 返回 `false`，`save`/`update` 返回 `null`，`deleteRule` 返回 `false`，并在控制台输出 `[ruleStorage] 保存规则失败`。调用方须检查返回值，避免误报成功。

-class RuleStorage {
-  private readonly STORAGE_KEY = 'testDataGenerator_rules';

+  | { type: 'start'; payload: WorkerStartPayload }
+  | { type: 'cancel' };
+
+type WorkerResponseMessage =

+
+interface WorkerStartPayload {
+  generationId: number; // 任务 ID，用于忽略过期响应
+  fields: FieldConfig[];
+  count: number;
+  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`

LingandRX	70b799aa2d	fix: add missing Toaster component to enable toast display (#65 ) The project was calling toast.success/error/warning from sonner in 7 files, but the <Toaster> component was never rendered in the React tree. This meant sonner stored toast data internally but no UI was ever displayed to users. Changes: - Create src/components/ui/sonner.tsx with shadcn/ui-style Toaster wrapper that integrates with ThemeModeProvider for light/dark theme support - Add <Toaster /> to AppRoot.tsx so it works across all entry points (popup, sidepanel, browser-tab) fix: always convert dots to underscores in i18n t() key lookup The t() function only converted dots to underscores when the key contained a colon (namespace:key format). Keys using dot notation like 'messages.copySuccess' were passed directly to chrome.i18n.getMessage() without dot-to-underscore conversion, causing lookups to fail silently and return empty strings - resulting in toast notifications with no text. Now all separators (both ':' and '.') are consistently converted to '_' regardless of format, matching the messages.json key convention. fix: position toast at bottom-center instead of bottom-right	2026-06-05 19:29:21 +08:00
