租客在待支付超时或取消的最后几十秒完成付款时，订单先被取消，乐刷的支付 结果几秒后才到，入账被判定订单不可支付而拒收。原先订单推进和支付单更新 在同一个事务里，订单一报错整笔回滚，支付单停在支付中且 paid_at 为空： 钱已在渠道，系统却毫不知情。乐刷重试十次后放弃，之后既补不回入账（订单 不再是待支付），后台人工退款也发不出去（退款要求原支付单是已支付）。 日志保留期内 13 天出了 5 笔，合计 4085.60 元。 - 取消前核对渠道：超时取消、租客取消、客服关单都先查一次渠道，已收款并 已推进订单就放弃取消，让支付正常入账而不是走退款。渠道异常时按未收款 继续，避免渠道一抖订单全卡住 - 回调兜底记账：订单确实已结束时不再回滚，把支付单如实记成已支付并写入 paid_at 与渠道单号，后台人工退款从此可用。退款仍由客服人工发起 - 客服关单：待支付订单按实际已收款减已退款的差额退，补上本次事故中关单 不生成退款的直接原因 - 补齐日志上下文：回调入账失败原先只有 error="order cannot pay"，现在带 支付单号、订单号、订单状态和金额；新增 ERROR「渠道已收款但订单无法入账， 需人工退款」作为唯一需人工介入的告警 Co-authored-by: Cursor <cursoragent@cursor.com>
