 ### 14.2 order_site 落地要点
 
-- **client_order_no 用 `task_no`**（`utils/random.ts` `randomId('DT', 6)` → `DT` + 12 hex，≤64 字符满足 affiliate_dash 限制）。order_site 自身无 client_order_no 字段，本地下单幂等由 `orders UNIQUE(provider, platform, shop_id, platform_order_id)` + `listTasks(order.id)` 已建不重建承担；affiliate_dash 侧幂等由 `client_order_no=task_no` 承担，preparePaidTask 失败重试可安全重放同一 task_no。
+- **client_order_no 优先用平台订单号**：单笔任务直接使用订单号；拆单使用 `订单号-序号`，均在 affiliate-dash 的 64 字符限制内。订单和任务集合创建后保持稳定，因此 `preparePaidTask` 失败重试会重放同一个幂等单号。
 - **preparePaidTask 同步拿到 order_no**（201 响应即含），写入 `context_json.affiliateDash.orderNo`；无需等回调。失败必须降级 `MANUAL_REVIEW` + `deps.notifyTaskAutoManualReview`（范式：kuaishou-feifei-executor.ts:36-51）。
 - **状态迁移路径**：见 §8 注 —— 领取页打开 `link_generated → claimed`，绑定 `→ waiting_binding`，submit 成功/回调 delivering `→ redeeming`，delivered `→ redeemed`（+核销），ship_failed `→ retry_pending`，cancelled `→ manual_review → closed`。
 - **回调幂等**：affiliate_dash 投递带 `X-Event-ID`，order_site 现无独立去重表 —— 建议 migration `013_affiliate_dash.sql` 新建 `webhook_events(event_id UNIQUE)` 去重表；事件处理用**状态合并式更新**（仿 `syncKuaishouFeifeiTaskStatus`，重复通知可重入）。接收方注意 `app.ts:31-38` 的 `express.json` 已保存 `req.rawBody`（验签必需），挂载回调路由时确认 rawBody 可用。
