PAYMENT_DESIGN §3 承诺的 internal/payment/channel.go 适配器接口此前不存在,微信硬编码在 manager/handler 里。补齐抽象: - channel.go:Channel 接口(Name/CreatePay/QueryOrder/VerifyCallback)+ 统一 PayIntent/PayResult + 渠道名常量。入参用基本类型不吃 *store.PaymentOrder,payment 包不反依赖 store。 - Wechat 实现 Channel(编译期断言 var _ Channel);QueryResult 归一为 PayResult;CreatePay 返回 PayIntent。 - Manager 从「持一个 *Wechat」改为渠道注册表:Get(name)/Available()/Status(name)/ReloadWechat; 按渠道名持有已装配实例,热重载不变。 - 回调路由收敛 /billing/callback/wechat → /billing/callback/:channel 按名路由(旧 notify URL 仍匹配); 查单/掉单补偿据 order.Channel 路由,不再写死微信。下单支持可选 channel(缺省 wechat)。 - 支付宝/Stripe 现在真·只差一个 adapter+注册。唯一未泛化:回调 ack 应答格式(现微信态,注释标明)。 - payment 包首个测试:Manager 注册表 4 用例(空/注册摘除/空配置/配置不全)。build/vet/test/lint 全绿。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
