 | 一件代发接收、SKU/箱唛库存 | 内部接收入口 `dropship/controller/DropshipOrderController.java` 的 `/internal/v1/lastleg/dropship/receive`，必须经 `InternalServiceTokenGuard`；版本化契约 `src/main/resources/openapi/lastleg-internal-dropship-v1.yaml`；处理 `dropship/service/DropshipOrderService.java`、`dropship/entity/`、`dropship/mapper/` |
 | 货物废弃、待审锁箱、审批扣减 | `discard/controller/CargoDiscardController.java`、`discard/service/CargoDiscardService.java` |
 | 客户拜访、派送状态与签收附件 | `customervisit/controller/CustomerVisitController.java`、`customervisit/service/CustomerVisitService.java`、`delivery/model/DeliveryStatusPolicy.java`；派送单返回服务端 `allowedActions/version`，状态只允许单调迁移，同状态幂等，完成后生成回访记录 |
+| 派送三类资料、摘要与历史证据 | `delivery/controller/DeliveryDocumentController.java`、`delivery/service/DeliveryDocumentService.java`、`delivery/gateway/DeliveryDocumentFileGateway.java`、`src/main/resources/openapi/delivery-documents-v1.yaml`；固定装车照片 `LOADING_PHOTO`、BOL文件（含签名）`BOL`、签收文件（POD签收/快递签收）`RECEIPT`，按已保存类别计数 `x/3`。每类0至20文件，文件精确绑定客户、派送单和类别；全量保存共用派送版本并记录不可变历史，替换删除仅解绑，未保存上传不计数、不授权下载，不增加派送完成门禁或签名识别 |
 | 异常订单与派送退回入仓 | `exceptionorder/controller/ExceptionOrderController.java`、`exceptionorder/service/ExceptionOrderService.java`、`exceptionorder/gateway/ExceptionEvidenceFileGateway.java`、`inventory/command/service/InventoryCommandService.java`；证据固定按客户、异常单 ID 和 `OVERSEAS_EXCEPTION_EVIDENCE` 校验。退回候选按原出库拣货事实冻结，不接受自由 SKU 或数量；异常按 `PENDING→PROCESSING→COMPLETED`（待处理可取消）、版本与幂等键流转。退回海外仓须把实收按原出库来源恢复到服务端校验的真实托盘/库位并写 `RETURN_STOCK_IN` 流水，库存恢复、异常完成与派送 `RETURNED` 在同一事务完成 |
 | 海外采购、客户下单、采购审核、客户/采购仓候选与操作流水 | `procurement/controller/`、`procurement/service/OverseasProcurementService.java`；客户入口要求 `merchant:cross-border:procurement` 且只取 Token 客户范围；OpenAPI `src/main/resources/openapi/overseas-business-v1.yaml` |
