+## 开发者注意事项（与源码同步）

+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。

 ### 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。

+  | { type: 'cancel' };
+
+type WorkerResponseMessage =

+  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`

+### ruleStorage 写入失败处理
+
+`ruleStorage.ts` 使用函数式导出（非 class），存储键为 `testDataGenerator_rules`，最多 `MAX_RULES = 20` 条。
+
+写入经内部 `setAll()` 完成；`localStorage.setItem` 抛错（如配额超限）时返回 `false`，并 `console.error`，**不会部分提交**：
+
+| 方法 | 写入失败返回值 | 常见失败原因 |
+| ---- | -------------- | ------------ |
+| `save()` | `null` | 达上限、规则不存在（更新时）、`setItem` 异常 |
+| `update()` | `null` | 规则不存在、`setItem` 异常 |
+| `deleteRule()` | `false` | 规则不存在、`setItem` 异常 |
+| `duplicate()` | 仍可能返回对象但数据未持久化 | 见源码：`duplicate` 未检查 `setAll` 返回值（已知缺口） |
+
+调用方应检查返回值后再展示成功 Toast。页面层参考 `FieldList.tsx`：`save`/`update` 返回非空才提示「规则已保存/已更新」。
+
+规则仅持久化 `name`、`description`、`fields` 及时间戳/使用统计；生成数量与导出格式由页面状态管理，不写入规则。
