 - 价格簿查询消费者依赖 `PriceBookQueryUseCase` 或稳定查询端口，不得反向依赖持久化 Mapper；移动旧查询类时同步更新生产调用、测试、Mock 与 import，避免同一职责在根 `repository/mapper` 和 `pricebookquery/` 双写。
 - 第三方回传必须签名、时间窗、防重放、请求哈希，并绑定订单货物和 File 证据；不得信任外部客户字段。
 - 稳定箱码映射以入库快照和 Order 货物明细为事实；订单审核创建入库单时必须幂等生成，打印接口只复用或补齐同一映射，用户是否下载箱唛不得决定箱码有效性。手工测量、墨家设备和 PDA 扫码统一通过 `InboundCartonLabelService` 校验客户、入库单、货物明细、总箱数/下标和有效批次，不得在测量时临时伪造箱码或接受跨客户、跨入库箱码。

 - 测量审核通过后直接进入 `WAIT_SPLIT`，费用仅作为独立初算和人工维护结果，不得阻塞或回退订单主流程；计费量、单价和附加费调整必须版本化并由服务端重算金额。状态或 DTO 变更时逐个检查 Order/Warehouse/File/Integration 消费者。
 - 客户箱规配置必须恰好保持四档且默认算法在四行一致；`ADD` 以实测尺寸为基准对三个维度分别增加命中箱规的尺寸值，`MULTIPLY` 使用当前客户唯一默认计费规则，并由服务端按规则中的规格档位选择系数。测量行必须保存实际尺寸、选用规则和算法快照，页面不得自行重算后覆盖服务端结果；计价使用用户确认的重量/体积选择值并纳入幂等请求哈希。
 - 报关、订舱和拖车引用的供应商必须通过 `WarehouseSupplierSnapshotService` 按 ID 向 Warehouse 校验：报关使用 `CUSTOMS`，订舱使用 `BOOKING`（不区分国内/国外 scope），拖车使用 `TRUCKING`；供应商必须为 `ACTIVE`。请求中的名称只能作为一致性提示，持久化名称必须来自 Warehouse 快照，禁止用自由文本绕过 ID、类别或启用状态校验。修改任一供应商引用 DTO、OpenAPI 或内部客户端时，必须同步检查三条业务链、Warehouse `supplier-v1.yaml`、数据库快照字段和对应契约测试。
