+## Why
+
+The front end currently supports WeChat payment and wallet balance payment, but it does not support the new backend Alipay WAP payment-link flow. This prevents users from completing package purchase and wallet recharge scenarios when Alipay is the selected method.
+
+## What Changes
+
+- Add Alipay as a supported payment method in package purchase, order list immediate payment, and wallet recharge flows
+- Handle backend `payment_link` responses for Alipay while preserving existing WeChat `pay_config` handling
+- Keep wallet balance payment behavior unchanged for package purchase
+- Refresh payment-related page state from backend status after the user returns from the Alipay payment link flow
+- Preserve current order creation, strong recharge, validation, toast, and list refresh behavior except where Alipay-specific branching is required
+
+## Capabilities
+
+### New Capabilities
+- `alipay-payment-link`: Support backend-provided Alipay payment links across package, order, and wallet payment entry points
+
+### Modified Capabilities
+
+## Impact
+
+- Affected code: `pages/package-order/package-order.vue`, `pages/order-list/order-list.vue`, `pages/my-wallet/my-wallet.vue`, `utils/payment.js`, `api/modules/wallet.js`
+- Affected UI flows: package payment method popup, order list immediate payment, wallet recharge popup, wallet recharge order immediate payment
+- No backend API path changes expected
+- Existing WeChat and wallet payment behavior must remain available
