 # 单测试环境数据库空库初始化
 
+`migrations/overseas/baiyue_lastleg/V38__allow_multi_order_delivery_returns.sql` 移除派送退回的旧全历史唯一索引，保留普通来源索引，支持同派送一次选择多张原订单各建异常。配套 Lastleg 批次行锁、总量校验及 Admin 多选；可重复执行，不改业务记录。已在本机应用并核对行数，远程 TEST 尚未执行。
+
 `20261104-unify-utf8mb4-0900-ai-ci.sql` 是本机 MySQL 8.4.11 五个业务库的排序规则汇总脚本，覆盖 `baiyue_event_bridge`、`baiyue_event_bridge_overseas`、`baiyue_firstleg`、`baiyue_lastleg`、`baiyue_order`。脚本已在本机执行并核验 209 张表、1,644 个文本字段；其他环境执行前必须核对实际字段定义和唯一索引冲突，不能默认部署。脚本只收敛旧的 Unicode 不区分大小写排序规则，保留有意使用的 `utf8mb4_bin`。
 
 退货仓租改为原托整托计费、余一箱仍计一托，现有阶梯不变。已有 Lastleg 库先执行 [整托计费结构增量](return-storage-rent-whole-pallet.sql) 增加 `ll_storage_rent_lot.charged_days`，再发布匹配的 Lastleg；源基线和海外空库基线已同步。实际出库事务推进已生成费用的截止库龄日，同托同计租日不重复收费。切换期间暂停相关出库、取消未消费预占，并逐单核对旧比例费用；脚本不修改既有费用、库存或资金。本次仅准备代码及脚本，未执行环境 SQL 或部署。
