+测试环境兼容提示：如果会会仍将上述组织充值订单发往 `/api/token/payment/huihui/virtual/notify`，而该环境未配置独立的虚拟支付密钥，旧地址会使用组织充值密钥验签并走相同的组织订单复核流程。该兼容入口不会处理微信直连虚拟支付订单；新接入仍应使用 `/org/notify`，生产环境不依赖此兼容行为。

 回调报文及签名协议尚未与会会确认。以下是本项目实现的拟议对接契约，会会服务端必须按此格式发送才能完成联调。接口代码部署与会会联调通过是两个独立状态。它不替代现有微信直连回调 `/api/token/payment/wechat/virtual/notify`。
