+整票库位块专项可在只跑 `orders,inbound-measurement` 时追加
+`--verify-pallet-location-guide true`。它在测量提交后核对
+`palletLocationGuide` 计数、每槽 `blockId/slotNo/reservationId/locationCode/slotStatus`、
+称重结果按 `weightResultId` 显式绑定槽位，并真实验证删除图片后原 reservation/location
+保留且转为 `RESERVED_EMPTY`。脚本只观测自然出现的共享 A0；不会为制造普通位不足批量停用库位。
+
 只验证真实集装箱号晚补门禁时，使用正式可选参数 `LATE_CONTAINER_GATE_ONLY=1` 并仍从总入口执行 `phase3-loading`。该模式使用本轮 marker 独立造数，固定验证无号 push、订舱关联、整份预装确认、PDA claim/batch、无号 complete `A0409`、LOADING 阶段首次补号和补号后 complete 受理；随后允许后台命令停在 `CABINET_EVIDENCE/A0409`，以证明柜号门禁已经消失且下一门禁来自未上传的五类柜级证据。该模式不继续完整报关或 LOADED 链，也不得与完整链同时解释为同一终态验收。
