+
+### Server：下载接口改造为一次性临时 URL 并绑定来源 IP
+
+- 文件下载流程由“业务接口返回可复用直链”改为“业务接口签发一次性临时 URL + 下载后立即失效”。
+- 新增下载入口 `GET /downloads/:ticket`，票据校验包含有效期、一次性消费和请求来源 IP 一致性。
+- 旧入口 `GET /files/:fileID` 已停用并固定返回 `403`，避免 fileID 直链被转发复用。
+- `downloadModel` 统一要求 `adminToken`，下载能力与管理权限保持一致。
+- 返回下载 URL 的业务接口已统一改为临时票据地址：`downloadModel`、`getPendingPanelFile`、`getIdentificationFileDownload`、`getControlFileDownload`、`getIdentificationConfig`、`getVolumeConfigFile`、`getVolumeConfigRequest`。
+
+涉及文件：
+
+- `server/src/app.js`
+- `server/test/server.test.js`
+- `ControlPanel/server-client.js`
+- `server/features.md`
+
+### 验证
+
+- 已完成 `server` 全量测试（21 项）通过。
+- 已完成 ControlPanel 无 GUI 内核联调测试通过（`model-handlers` 与 `license-manager` 相关用例）。
+- 已重启 `reinloop-server.service` 并验证：同一临时下载 URL 首次下载成功，二次访问返回 `403`。
+
+### Server + ReinLoop：设备分路由与最小权限访问
+
+- 新增 `POST /device` 设备侧路由，ReinLoop 通过 `deviceAuth`（`licenseId` + `deviceId`）换取短期 `deviceToken` 后访问设备接口。
+- 设备侧接口采用白名单权限，不再使用 `adminToken`，并强制按 `deviceId` 隔离目录和模型访问范围。
+- ReinLoop 客户端核心模块已切换为 `/device` 访问链路：设备心跳、模型列表与下载、辨识配置下载、容积请求、辨识反馈、控制与辨识结果上传申请。
+- ReinLoop 离线宽限默认调整为 `100` 小时（`REINLOOP_LICENSE_OFFLINE_HOURS` 默认值）。

+## 设备侧鉴权与分路由
+
+`/device` 仅用于 ReinLoop 客户端，禁止使用 `adminToken`。
+
+调用方式：
+
+1. 先 `POST /device`，`type=deviceAuth`，字段 `licenseId`、`deviceId`。
+2. 服务端校验许可证状态（存在、未过期、未撤销、deviceId 匹配）后签发 `deviceToken`。
+3. ReinLoop 后续调用 `/device` 白名单接口时携带 `deviceToken`。
+
+`deviceToken` 默认有效期由 `DEVICE_TOKEN_TTL_MS` 控制（默认 15 分钟）。
+
+离线宽限由 ReinLoop 客户端控制，当前默认 `REINLOOP_LICENSE_OFFLINE_HOURS=100`（100 小时）。
+
+## 下载安全调用链
+
+统一链路为：业务 `POST /`（鉴权） -> 返回临时 URL -> `GET /downloads/:ticket`（一次性消费）。
+
+安全校验点：
+
+- `POST /`：按业务类型执行权限校验。
+- `GET /downloads/:ticket`：
+	- 票据存在且未过期（`DOWNLOAD_URL_TTL_MS`，兼容旧环境变量 `DOWNLOAD_TOKEN_TTL_MS`）。
+	- 票据仅可消费一次，成功下载或校验失败后均失效。
+	- 下载请求来源 IP 必须与签发票据的 `POST` 请求来源 IP 一致。
