       summary: 按整柜批量生成剩余入库计划
-      description: 权限 platform:overseas-warehouse:inbound-order:create；使用稳定 sourceContainerBookingId 锁定整柜订单，并要求全柜尾程订单及既有有效计划的真实 containerNo 与接柜仓快照一致。已有有效计划保持不变，只为剩余尾程订单/入仓码分别生成独立计划；响应按柜内订单稳定顺序返回全部已有及新增计划。整批原子且幂等，剩余为0时直接返回已有结果；任何快照漂移均冲突且不部分写入。
+      description: 权限 platform:overseas-warehouse:inbound-order:create；调用方必须先取柜级预览并原样回传 snapshotVersion/snapshotHash。服务端以 sourceContainerBookingId 建立唯一 Saga 命令，先向海外仓资源服务按票、按托盘批量预留真实 palletId/palletCode/locationId/resourceLockId，再在一个本地事务中锁整柜并为每票生成独立计划，最后确认资源批次。本地任一票失败时整柜回滚并补偿资源；本地已提交但远端确认失败时重放只重试确认。同柜不同 Idempotency-Key 也不会产生第二批资源。
