-- 货物废弃增量汇总（2026-10-14），MySQL 8.0.16+，可重复执行。
-- 目标仅 baiyue_lastleg，连接实例和凭据由执行者指定。
-- 前提：已有尾程入仓箱、退货库存及出库基线；不是空库初始化脚本。
-- 覆盖基础废弃表、PDA完工、退货箱废弃、照片、通用库存及部分选箱。
-- 不回填历史单据、不补造出库单、不修改库存数量、不执行业务DML。
-- File复用已有文件表，无需修改 baiyue_file 或仓储资源库。
-- 完整执行，遇错停止，不使用 --force；DDL隐式提交，失败修正后可重跑。
-- 已有同名表/列/索引沿用，不修复任意未知旧结构，末尾输出结构供核对。
