+
+## 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。
+
+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`。

+

+| `save()` / `update()` / `deleteRule()` / `duplicate()` | 写入；失败时返回 `null` 或 `false` |

+| `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`

+- 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)`。
