 # bat-api Admin Panel
 
-This directory is reserved for the future player-facing `bat-api` management
-panel. The current backend exposes a non-mutating index at `GET /admin/` that
-returns JSON links for health, readiness, bootstrap, release, resources, and
-OpenAPI. `GET /admin/schedules` and mutating
-`/admin/control/schedule-{add,update,remove,run}` routes are protected by the
-configured admin token and forward the Rust-owned schedule contract.
-`GET /admin/schedules` accepts optional `id`, `group`, and `enabled` filters.
-`POST /admin/control/translation-task-update` uses the same token and forwards
-the narrow `translation.task.update` provider-worker status contract.
+本目录预留给后续 `bat-api` 管理面板。当前后端已提供只读入口
+`GET /admin/`，返回 health、ready、bootstrap、release、resources 和 OpenAPI
+链接。
 
-The production panel must reuse the same HTTP authentication, rate limiting,
-access logging, reverse-proxy handling, and no-store dynamic response policy as
-the resource API. Static frontend assets are not implemented yet. See
-`docs/reports/GO_STATUS.md` for the current component boundary and status.
+需要配置 `BAT_API_AUTH_TOKEN` 的接口：
+
+- `GET /admin/schedules`：转发 Rust 持有的 schedule 查询，支持 `id`、`group`
+  和 `enabled` 过滤。
+- `POST /admin/control/schedule-{add,update,remove,run}`：转发
+  `schedule.*` 计划控制。
+- `POST /admin/control/translation-task-update`：转发
+  `translation.task.update`，供外部 provider 流程回写任务状态。
+- `POST /admin/control/translation-worker-run`：转发
+  `translation.worker.run`，触发 Rust provider worker。
+- `POST /admin/control/translation-proofread`：转发
+  `translation.proofread`，把汉化 workflow 标记为人工校对中。
+- `GET /admin/translation/tasks`：转发 `translation.tasks`，按分页、release、
+  TextUnit、状态和失败原因过滤查询 worker 状态。
+- `GET /admin/translation/handoff`：转发 `translation.handoff`，读取当前
+  release 的完整翻译交接视图。
+
+正式前端必须复用资源 API 的 HTTP 鉴权、限流、访问日志、反代处理和动态响应
+`Cache-Control: no-store` 策略。静态前端资产仍为 not implemented，尚未作为
+本目录的稳定交付物。当前组件边界见 `docs/reports/GO_STATUS.md`。
