+- 仓储转运按托盘分别保存箱数、长宽高（cm）和毛重（kg），体积按本托尺寸计算；SKU件数逐种核对差异，不以预报箱数强制核平。箱唛沿用客户预报编号，PDA不得另造新箱号；测量完成前客户与平台可增加整单预报箱数，不选SKU，箱内SKU以PDA实点为准，PDA刷新时合并新箱并保留本机草稿，清点提交携带forecastPackageCount拦截旧快照。生成托盘号后锁定该卡测量数据，必须取得服务端绑定确认且至少有一张现场照片才能完成打托；完成请求提交稳定幂等键、照片文件 ID，SKU实收件数有差异时在完成入口弹窗必填差异原因，不重复提交整份托盘测量。重新进入从详情恢复托盘和鉴权照片；标签使用服务端 `labelDownloadPath` 下载 PDF，打开文档不等于真机打印完成。
 
 - 换标目标确认即提交拆托合托，不再二次点击底部提交。`RelabelPalletWork.vue` 按当前轮次 `PALLET_BIND` 最新记录提供逐箱改绑，扫描新目标后弹窗确认，使用既有 `relabel-disassemble` 精确来源路径（不传 `actualSource`）；同目标不发写请求。服务器持有库存、托盘版本与幂等约束，已排车或出库禁止直接改绑。离线回归 `tests/relabel-pallet-work.test.mjs`，不等同真机验收。
