+## 与现有支付交互对齐（2026-09-09 第三次补丁）
+
+本节取代前文“显式确认/继续支付/重新支付弹窗”的交互说明，遵循用户要求，不新增确认弹窗。
+
+- 用户点击支付即继续：原单有效时直接续付；渠道确认旧单关闭后，直接继续当前页面的下单请求。保留服务端防重复支付校验。
+- 微信、支付宝和抖音共用现有支付成功页 `pages/order_package/order_submit_ok/order_submit_ok`，不新建成功页，不仅显示成功 Toast。
+- 抖音正常回调、再次点击查到已支付、冷启动查到已支付，均在服务端确认后跳转成功页。
+- 从抖音返回 App 时，即使 SDK 回调丢失，也允许 onShow 查单结束等待；与迟到 SDK 回调竞争时只处理一次。查单失败或 pending 不跳成功、不解锁。
+- 页面栈满时使用 redirectTo 进入同一成功页；两种跳转均失败则保留待查记录，下次重试跳转，不再次付款。
+- 本次仅修改前端 JavaScript、测试及文档，不改后端、接口、SQL、原生插件和支付页面样式。仍依赖上一补丁的后端与原生插件 0.2.0。
+
+本地 33 项支付测试通过，涵盖无弹窗、成功跳转、丢失回调、回调竞争、账号切换、页面栈满以及微信/支付宝成功页回归。尚未进行真机实付。
