+  title: 平台排车车辆与司机证据内部文件契约
+  version: 1.0.0
+  description: >-
+    复用 InternalBusinessFileController 的现有通用内部入口，不新增公开文件路由。
+    两类证据均固定平台 tenantId=0，businessId 为排车内部正数 Long ID 的十进制表示，
+    不使用车辆 ID、司机 ID、车牌或客户 ID。车辆与司机证据分别使用
+    OVERSEAS_DISPATCH_VEHICLE_EVIDENCE、OVERSEAS_DISPATCH_DRIVER_EVIDENCE，不可互换。
+    File 校验内部服务令牌、平台归属、正数业务 ID、文件非空、最大 10MiB（10485760 字节，包含边界）、
+    PDF/JPG/PNG MIME 及对应内容签名。元数据和下载按 tenantId、businessType、businessId、fileId
+    联合查询 ACTIVE 且未删除文件，错车或错类别均视为归属不匹配，下载前完成归属校验。
+    上传生成不可变文件和真实元数据，不自动绑定证据或通过审核，不返回公开 URL 或存储路径。
+    Lastleg 负责排车存在性、仓库与角色权限、当前及历史附件引用和审核状态；File 不查询 Lastleg 业务表。
+    本文只描述排车网关实际消费的上传、元数据和内容三个操作，不改变通用文件接口的其他用途。
+    统一异常处理使用 HTTP 200 JSON 业务错误，调用方必须检查 code；内容接口错误也返回 JSON，不能当作文件。
