 - 客户入库费用只在登录客户范围、测量审核通过、`feeStatus=SENT` 且存在已发布明细时可见；确认必须具备 `merchant:order:edit`，携带当前 `expectedFeeVersion` 与幂等键。成功后记录确认成员和时间并将该费用版本永久锁定，平台不得再调整；旧版本、未发送或重复异参确认均返回冲突，不做兼容覆盖。
 - PDA 拣货以 `fl_inbound_carton_label.box_code` 对应的稳定箱唛箱码为扫描身份；审核建单、重复打印、手工测量和墨家测量复用同一映射，版本字段只用于并发控制，不进入扫码文本。一个有效且未重复的箱码扫描表示拣出一箱，不得以 SKU、商品件数或页面展示字段替代箱码。任务下发与提交契约见 `src/main/resources/openapi/phase3-pda-convergence-v1.yaml`。
 - PDA 部分拣货生成二级子入库单时，数量必须守恒：`已拣数量 + 子单数量 = 拣货前主单可用数量`。子单只允许一层，不能继续拆分。
-- 测量提交按 `max(已确认称重图片数, ceil(实测体积 / 默认托盘容量))` 预留整票库位块；实际称重图片数与预留槽位数独立。Firstleg 必须显式保存 `weightResultId -> blockId/slotNo/reservationId/locationId/locationCode`，按 `confirmedAt + weightResultId` 稳定顺序绑定块内最小空槽，禁止按列表下标推断。普通位不足时 Warehouse 可将剩余槽位放入共享 A0，不阻断测量提交。
+- 首张称重图片确认时按 `max(已确认称重图片数, ceil(实测体积 / 默认托盘容量))` 预留并确认整票库位块；后续确认绑定最小空槽，所需槽数增长时通过 Warehouse `/blocks/expand` 原子追加，既有 `blockId/slotNo/reservationId/locationId` 不得变化。测量提交只校验并复用已存在权威块，不得首次分配。Firstleg 必须显式保存 `weightResultId -> blockId/slotNo/reservationId/locationId/locationCode`，按 `confirmedAt + weightResultId` 稳定顺序绑定，禁止按列表下标推断；普通连续位不足的新增槽由 Warehouse 放入共享 A0，不阻断确认。
 - 删除称重图片只解除图片和托盘快照绑定，将槽位恢复为 `RESERVED_EMPTY`；槽位和整票块继续归当前入仓码。解绑失败时不得调用文件删除，文件删除失败时本地解绑和重量结果删除必须回滚。
 - 头程快照必须保存 Warehouse `blockId + slotNo + reservationId`；A0 可被多个整票块共享 `locationId`，业务资源身份始终使用 `reservationId`，不得把 `locationId` 当作唯一标识。
 - PDA 部分拣货不得释放块内单槽；存在余量子单时通过 `/internal/warehouse/v1/pallet-locations/blocks/transfer` 将整段转移给子单。整票全部拣完时只通过 `/internal/warehouse/v1/pallet-locations/blocks/release` 一次性释放全部普通位和 A0 预约，禁止恢复逐槽 `settlements/release-selected` 协议。
