 用户授权继续后，已补齐 EPay 回调成功状态、金额（含手续费）、商户及渠道归属校验，并按官方 V1 规则生成签名。隔离测试 5 项、20 个断言通过，覆盖正常/重复回调、错误金额/状态/商户/渠道、缺失/错误签名、取消订单和冲突交易号。语法检查通过。修正已提交推送并通过 Git fast-forward 部署至生产版本 60457487726b95dd7811eea16a625b01cf5c9d69；发布前备份了旧插件和生产既有差异，发布后插件哈希、PHP-FPM 与 Horizon 状态已核对。生产调用空中支付商户查询 API 返回 HTTP 200、业务成功且商户正常。尚未进行真实付款或真实成功回调验收。用户随后要求仅线上联调，本地支付配置保持不动。服务商支付测试页面目前仅展示支付宝按钮；微信通道可用性尚未确认，不能把网站启用微信配置视为通道验收完成。
 
+## 不付款验收（2026-10-11）
+
+用户明确要求以不做真实支付的方式验收。新增真实控制器与 PaymentService/EPay 插件调用链的隔离测试，使用 SQLite 内存数据库、虚构商户及订单；拦截订单开通任务、禁止外部 HTTP 请求，不操作正式订单。与插件单元测试合计 8 项、53 个断言通过。成功回调返回 success、记录回调号并只派发一次开通任务；签名正确但状态、金额、商户、支付类型或订单不匹配，以及取消订单均不会开通。
+
+本轮验收目标是代码逻辑及接口可达性，不包含真实收款、服务商实际成功回调和正式套餐开通；微信通道仍未得到真实验证。线上隔离运行及回调入口检查完成后单独追加结果。
