+## 2026-05-13 微信小程序支付以后端通知为唯一入账事实
+
+- 背景：“我的”账户充值需要接入微信小程序支付，同时保留本地 / H5 mock 支付联调能力。
+- 决策：`paymentChannel = "mock"` 继续创建即 paid 订单并立即入账；`paymentChannel = "wechat_mp"` 先在 `profile_recharge_order` 写入 `pending` 订单，再由 `api-server` 调微信支付 JSAPI 下单并返回小程序 `wx.requestPayment` 参数。小程序或 H5 的支付成功回调只触发刷新，不直接发放光点或会员；最终入账只由 `/api/profile/recharge/wechat/notify` 验签、解密并确认 `trade_state = SUCCESS` 后完成。`provider_transaction_id` 保存微信支付平台交易号，用于对账、查单、退款和客服排障。
+- 影响范围：`profile_recharge_order` 表、SpacetimeDB 充值 procedure、`api-server` 微信支付客户端、小程序 native 支付页、H5 充值弹窗与共享 contract。
+- 验证方式：执行 `npm run typecheck`、`npm run test -- src/components/rpg-entry/RpgEntryHomeView.recharge.test.tsx`、`cargo test -p module-runtime recharge --manifest-path server-rs/Cargo.toml`、`cargo test -p api-server wechat_pay --manifest-path server-rs/Cargo.toml`，后端联调仍用 `npm run api-server` 和 `/healthz`。

 - 背景：修改密码原本只递增 `token_version`，旧 access token 会失效，但旧 refresh cookie 仍可通过 `/api/auth/refresh` 重新签发新 token，不符合“改密后全设备强制下线”的账号安全预期。

+## 微信支付回调验签不要用商户私钥
+
+- 现象：微信小程序支付下单能返回 `prepay_id`，但真实支付通知验签失败，或者本地实现误把商户 API 私钥当作回调验签 key。
+- 原因：商户私钥只用于商户请求微信支付和生成小程序 `paySign`；微信支付通知的 `Wechatpay-Signature` 需要使用微信支付平台公钥或平台证书公钥验签，并按通知头里的平台序列号匹配。
+- 处理：api-server 真实微信支付配置同时需要商户私钥与微信平台公钥：`WECHAT_PAY_PRIVATE_KEY_*` 用于签名，`WECHAT_PAY_PLATFORM_PUBLIC_KEY_*` 与 `WECHAT_PAY_PLATFORM_SERIAL_NO` 用于通知验签，`WECHAT_PAY_API_V3_KEY` 只用于解密通知 resource。支付成功后只通过通知里的 `out_trade_no` 确认本地 pending 订单，并保存 `transaction_id` 到 `profile_recharge_order.provider_transaction_id`。
+- 验证：mock 通知测试只能覆盖本地回调推进；真实环境还需用微信支付平台公钥、真实通知头和 API v3 密钥验证签名与解密链路。

 ## 2. 产品规则

 ### 2.1 光点充值套餐

-| productId | 光点 | 金额分 | 徽标 | 说明 |
-| --- | ---: | ---: | --- | --- |
-| `points_60` | 60 | 600 | 首充双倍 | 首充送60光点 |
-| `points_180` | 180 | 1800 | 首充双倍 | 首充送180光点 |
-| `points_300` | 300 | 3000 | 首充双倍 | 首充送300光点 |
-| `points_680` | 680 | 6800 | 首充双倍 | 首充送680光点 |
-| `points_1280` | 1280 | 12800 | 首充双倍 | 首充送1280光点 |
-| `points_3280` | 3280 | 32800 | 首充双倍 | 首充送3280光点 |
+| productId     | 光点 | 金额分 | 徽标     | 说明           |
+| ------------- | ---: | -----: | -------- | -------------- |
+| `points_60`   |   60 |    600 | 首充双倍 | 首充送60光点   |
+| `points_180`  |  180 |   1800 | 首充双倍 | 首充送180光点  |
+| `points_300`  |  300 |   3000 | 首充双倍 | 首充送300光点  |
+| `points_680`  |  680 |   6800 | 首充双倍 | 首充送680光点  |
+| `points_1280` | 1280 |  12800 | 首充双倍 | 首充送1280光点 |
+| `points_3280` | 3280 |  32800 | 首充双倍 | 首充送3280光点 |

 光点充值固定为 `¥6 / ¥18 / ¥30 / ¥68 / ¥128 / ¥328` 六个档位。全部档位参与首充双倍：用户历史上没有 `points_recharge` 流水时，本次购买到账光点为基础光点与等额赠送光点之和；已有充值流水后只到账基础光点。实际到账光点写入交易流水，余额以 SpacetimeDB projection 为准。

 ### 2.2 会员卡套餐

-| productId | 类型 | 天数 | 金额分 | 权益 |
-| --- | --- | ---: | ---: | --- |
-| `member_month` | 月卡 | 30 | 2800 | 免光点回合数100，每日签到加成0% |

-| `member_year` | 年卡 | 365 | 24800 | 免光点回合数100，每日签到加成210% |

 ## 4. 前端交互

 1. “我的”页会员充值按钮打开独立弹窗，不在当前面板下方展开。
 2. 弹窗顶部标题为 `账户充值`，右上角关闭。
 3. 默认打开 `光点充值`，可切换到 `会员卡充值`。
-4. 点击套餐后调用下单接口，按钮进入处理中状态，成功后刷新 `profileDashboard`。
+4. 点击套餐后调用下单接口，按钮进入处理中状态；小程序环境走 native 支付页拉起 `wx.requestPayment`，支付页返回后刷新 `profileDashboard`。
 5. 弹窗内不写大段说明文案，只保留必要金额、光点、会员权益和状态反馈。
 6. 会员卡充值区以套餐卡片优先展示周期、价格和处理状态；移动端单列，桌面端三列，权益表允许横向滚动，避免小屏挤压。
