+#### GitHub Token 授权
+
+GitHub Token 是可选的管理员配置，可在设置页或首次初始化页通过 GitHub Device Flow 授权，
+也可以直接保存已有的 PAT。授权接口只返回脱敏状态，不会把访问 Token 或刷新 Token 放进响应。
+
+已完成初始化的实例使用登录态超级管理员接口：
+
+| 方法 | 路径 | 说明 |
+| :--- | :--- | :--- |
+| GET | `/api/v1/github/auth/status` | 查询 Token 是否已配置、是否有效、来源和脱敏摘要 |
+| POST | `/api/v1/github/auth/start` | 申请设备码；响应包含 `session_id`、`verification_uri` 和 `user_code` |
+| POST | `/api/v1/github/auth/poll` | 请求体 `{"session_id":"..."}`，轮询授权状态 |
+| POST | `/api/v1/github/auth/manual` | 请求体 `{"token":"..."}`，保存手动 PAT |
+| DELETE | `/api/v1/github/auth/token` | 清除 Token 和 OAuth 刷新元数据 |
+
+首次初始化窗口使用同样的操作，但路径前缀为 `/api/v1/login/github-auth`，例如
+`/api/v1/login/github-auth/start`；这些接口只在系统尚未创建用户时开放，初始化完成后返回
+`409`，不应作为已初始化实例的未认证管理入口。
+
+`GITHUB_TOKEN` 属于敏感运行时设置，通用环境设置接口只返回脱敏值。需要访问私有仓库或执行
+写操作时，仍须提供具备对应 GitHub 仓库权限的 Token；设备授权流程本身不替调用方扩大仓库权限。
+
 客户端可发送 `X-MoviePilot-Locale: zh-CN|zh-TW|en-US` 或 `Accept-Language`。后端会按当前请求语言直接翻译顶层 `message`；未提供语言头时使用简体中文，翻译缺失时回退原文本。SSE 和业务数据中原有的 `text_i18n`、`error_i18n` 等展示字段继续保留。
 
 `GET /api/v1/login/wallpaper` 会将壁纸 URL 放在 `data` 字段中。`POST /api/v1/user/avatar/{user_id}` 会以 `data.filename` 返回原始文件名。上述接口的 `message` 均不承载业务数据。
