 `db/warehouse-transfer-consolidated-incremental-20261015.sql`：仓储转运近期本地增量汇总，固定 `USE baiyue_lastleg`，适用已有 Lastleg 基线的本地/开发 MySQL 8。依次合入 `warehouse-transfer-outbound-incremental.sql` 和 `warehouse-transfer-carton-counting-incremental.sql`，前者已覆盖旧 `dev-warehouse-transfer-pallet-lifecycle-incremental.sql`，无须重复跑旧生命周期补丁。包含审核、打托/照片、换标、目的地/出库/派送结构、实收箱数，以及逐箱尺寸、重量、实点件数、清点幂等、差异原因、箱所属托盘和独立 SKU 申报件数。只执行 DDL/元数据查询，无业务 DML；不回填单据或修改库存。实例和凭据由操作者在数据库客户端外部提供，无内置连接信息或报告文件。需支持 DELIMITER 和 CREATE ROUTINE/ALTER/INDEX 权限，整文件串行执行，遇错停止，不使用 --force；可按缺失结构检查重复执行，不修复任意同名异构旧表。末尾 `missing_carton_and_quantity_columns=0`、`inbound_pallet_unique_index=READY`、`migration_result=WAREHOUSE_TRANSFER_RECENT_SCHEMA_READY` 表示本轮列/索引核对通过；同客户重复托盘号会报告 INDEX_BLOCKED，不擅自更改旧托盘号。仅整理文件不表示目标库已经执行；连接必须由操作者明确选中，不重放 `deploy/sql/海外区域统一增量-MySQL8.sql` 空库基线。
