 ## 作业流程原则
 
 - 扫码是主路径：输入焦点、连续扫描、防抖、重复码、无效码、错箱和扫描反馈必须作为一等场景处理。
+- 拣货扫描身份是后端下发的稳定箱唛箱码 `boxCode`；一次有效且未重复的箱码扫描表示拣出一箱。SKU、商品件数、入库单号和页面展示文案只用于辅助识别，不得作为扫码匹配键或拣货计数单位。
 - 进入任务时由服务端标记“拣货中”；扫描结果先写入绑定作业员、任务和柜次的设备持久化草稿，仅在点击提交时批量写后端，禁止逐码提交。
 - 允许部分拣货和跳拣，但每个未完成项必须填写异常原因；存在未解决异常时任务挂起，不能完成或推进 `LOADED`。
 - 作业提交使用对员工不可见的轻量幂等标识和服务端版本；重复提交返回原结果，版本冲突提示刷新后重试，不静默覆盖。
