 - 预约规划只声明 `AppointmentSourceLinker` 端口；入仓域负责创建入口与关联明细实现，入仓请求声明自己的来源 DTO，再映射到规划模型。公开 JSON、事务及来源校验保持不变，规划包不反向依赖入仓实现。
-- 车队商业单使用本域的收货证据和签收快照；派送域实现车队声明的证据端口并提供完整签收事实，车队不再导入派送实体、Mapper 或完成策略。商业单编号保持原 LB/TR 规则，由本域生成；`fleet.business` 不反向依赖 `fleet.trip`。既有散板、卡车商业单的同库写入不在此次拆分范围，本次门禁通过不代表完成全域解耦。
+- 车队商业单使用本域的收货证据和签收快照；派送域实现车队声明的证据端口并提供完整签收事实，车队不再导入派送实体、Mapper 或完成策略。商业单编号沿用 LB/TR 前缀，通过共享编号组件按工作区 `docs/业务单据编号契约.md` 分配，各入口共用本库日流水；`fleet.business` 不反向依赖 `fleet.trip`。既有散板、卡车商业单的同库写入不在此次拆分范围，本次门禁通过不代表完成全域解耦。

 - 平台导出作为组合入口，仅登记 `LastlegExportProviderService` 对 12 个公开查询服务与 DTO/投影的引用，不开放整个切片；车辆仍限应用层。排车规划适配器只使用车队公开规划和收货端口。采购对海外主数据的旧依赖已不存在，移除该旧许可及入向断言。
 - 反向检查继续拒绝新消费者、导出直连持久化、车辆应用层外向依赖和任何主源码包循环。分析器继续按既有显式 import、静态 import 及同包类型引用规则检查；本次不改变其识别范围。
