 ## 后续迁移规则
 
 迁移新页面时：
 - 优先替换对应 Tab 的根 ViewController。
 - 保持每个 Tab 自己的 `TabNavigationController` 导航栈。
-- 跨 Tab 跳转通过 `AppRouter.select` 切换 Tab。
-- 需要从首页或全局入口进入订单核销时，优先使用 `AppRouter.selectOrders(entry:)` 或 `AppRouter.routeToOrderVerification(scannedCode:)`。
-- Tab 内跳转通过当前 Tab 的 `RouterPath.navigate` 或扩展后的 `AppRoute` 处理。
+- 跨 Tab 跳转通过 `AppNavigator.selectTab` 或对应业务入口方法执行。
+- 需要从首页或全局入口进入订单核销时，优先使用 `AppNavigator.openOrdersEntry(_:scannedCode:)`。
+- Tab 内跳转通过 `AppNavigator.push(_:from:)` 或扩展后的 `AppRoute` 处理。
 - 普通业务子页面默认隐藏 TabBar；只有确有产品需求时，才在 `AppRoute` 策略中单独放开。
 - 真实业务页面接入后，应同步补充该模块文档和单元测试。
