 ### 预约、车队与导出依赖收口（2026-10-12）

 - 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。
 - 退货客户引用与转仓 FBA 目录各由本域内部客户端读取原权威服务，移除对车队客户端的借用；接口、令牌及 URL 配置不变。退货合箱共用 PDA 仓身份、转仓实收共用仓储资源网关，两条精确类边在基线中登记。
 - 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。

 `fleet.ownedbusiness`只为原排车装车后的自有车辆组合运营资料。五条精确引用限`OwnedBusinessModels→DispatchViews`、`OwnedBusinessProjection→DispatchContracts`、`OwnedBusinessQueryService→DispatchContracts/DispatchTypes/DispatchDetailReader`，均为`dispatch.port`公开事实或只读应用端口；不增加`fleet→dispatch-delivery`通用许可，不共享原排车实体、Mapper或具体Service。原详情适配器在dispatch内部委托唯一提供者。`DispatchAggregateService→OwnedBusinessOwnershipCapture`仅在原装车事务捕获归属，不能反向调用运营查询；捕获失败随原确认回滚。反向合同拒绝具体持久化/Service引用、其他消费者借用端口许可及任何包循环。

 车次关联客户排车单新增 `dispatch-delivery→fleet`：fleet声明 `FleetDispatchGateway`，dispatch内适配器锁定自身排车/出库/派送并同步车和司机快照；子排车修改与发车使用fleet公开的关联门禁。fleet不导入dispatch实体、Mapper或业务服务，因此不新增双向切片依赖。车次与客户单据的归属不变，关联和同步处于同一Lastleg事务；客户单据已经开工时不允许通过改派覆盖执行事实。

-当前分析器把 `wallet.WalletCommandOutboxService` 归入 `shared-technical`，它依赖尾程Outbox实体/Mapper；粗粒度图因而存在 `fleet→shared-technical→tailleg-handoff→dispatch-delivery→fleet` 聚合环。不能把这一聚合环等同于fleet包或Spring组件循环，也不能宣称切片图无环。门禁检查实际包无环，fleet仅允许上节自有运营的五条公开只读引用，dispatch只使用公开端口/门禁；粗粒度切片图保留为耦合报告，不因门禁通过隐去聚合环。
