 - 海外业务 Token、PDA 权限和可信身份最终由 Gateway 与服务端校验；前端不得用工作台 `available`、本地客户 ID 或仓库 ID 代替授权和资源归属校验。
 - 排车和出库入口只调用专用 PDA 接口；客户与绑定海外仓由 Token、Gateway 和服务端解析，前端不提交 `customerId`、`warehouseId`，也不展示内部数据库 ID 作为业务编号。动作资格、版本和失败处理见本文件排车条目，装车中可同步上传五类照片，每类1至5张，装车确认与资料齐全两项均完成后服务端自动生成派送并发车，装完但资料未齐时留在装车后；照片API为 `/pda/v1/last-leg/dispatches/{dispatchNo}/loading-documents`，前端不补派送费用。完成成功后不得重复提交；PDA 不直接创建派送单，平台与客户的读取范围遵循现行契约。
 - 生产仓租功能尚未配套发布，当前 main 的排车拣货、普通出库、整托出库和废弃确认直接调用既有库存命令，不请求 `/storage-rent/preparations`。保留原始货源参数、箱数、版本和 `idempotencyKey`；实际库存接口的业务失败与网络错误照常上报，不吞掉 404、不自动重试或伪造成功。未来启用仓租须以后端接口、数据库及资金链路配套上线为前提。定向回归为 `tests/fulfillment-stock-commands.test.mjs`，覆盖四类命令单次提交、参数保留、版本/防重校验与失败传播；离线测试不代替生产实货验收。
