 - 修改 `apps/frontend/src`：Vite 自动 HMR

 63. 新增 `src/services/admin/admin-order-read-helpers.js` 与 `src/services/admin/admin-webhook-read-helpers.js`，订单列表汇总与 webhook 事件映射已按领域独立
 64. `admin-read-service / admin-write-service / admin-service` 已全部改为直接依赖 inventory / order / webhook / task / shared 五类 helper，读侧 helper 拆分阶段可以收口

+本轮已落地：
-- `npm run start`

-- Docker 开发 / 部署
+1. 新增 `tsconfig.build.json`
+2. `npm run build` 输出 `dist`，并复制数据库 migration SQL
+3. `npm run dev` 改为 `tsx watch --clear-screen=false --include config src/index.js`
+4. `npm test` 改为 `node --import tsx --test ...`
+5. `npm run db:migrate` 改为 `tsx src/db/migrate.js`
+6. `npm run start` 改为 `node dist/index.js`
+7. 生产 Dockerfile 改为 builder 阶段编译，runtime 阶段复制 `dist`
+8. 新增 `tsx` 和 `@types/pg`
+9. 首批真实源码迁移到 `.ts`：
+   - `src/db/client.ts`
+   - `src/utils/time.ts`
+   - `src/utils/random.ts`
+   - `src/utils/money.ts`
+   - `src/utils/json.ts`
+   - `src/repositories/claim-token-repo.ts`
+   - `src/repositories/task-event-repo.ts`
+   - `src/repositories/admin-audit-log-repo.ts`
+10. Docker 内验证通过：
+   - `npm run typecheck`
+   - `npm run build`
+   - `npm test`
 
 ## 下一步建议
 
 第一批继续推进时，建议按这个顺序：
 
-1. 为 `admin` 路由层继续补响应模型与审计 payload 的共享类型，减少 `unknown` 到处就地断言
+1. 将 `src/types/*.js` 从 JSDoc typedef 正式改写为 `export type` 的 `.ts` 文件，并逐步更新引用
-2. 继续补 repository / service 的边界约束，但不急着改 `.ts` 扩展名
+2. 继续迁移低风险 repository：`order-item-repo`、`message-delivery-repo`、`webhook-event-repo`
-3. 恢复并固定 `npm --prefix apps/backend run typecheck` 为日常校验步骤，确保本地与 CI 环境都能直接执行
+3. 拆分并迁移 `runtime.js`，把 env 解析、默认配置加载、配置合并分开
 4. 为 webhook、库存换码、自动发货补测试
