 - **配置**：`[jimeng]` 段，AK/SK 走 env（`BOOSAPI_JIMENG__ACCESS_KEY` / `__SECRET_KEY` / 可选 `__SESSION_TOKEN`），不硬编码；`enabled=false` 时路由返回 503「能力未启用」。
 - **首版范围**：图生视频只支持 `image_urls`（公网图 URL），前端上传 → 转存留二期；`frames ∈ {121(5s), 241(10s)}`，`aspect_ratio` 白名单。
 
+### 即梦在「站点管理 / 连接管理」里的特殊处理（platform=`jimeng`）
+
+即梦作为一个 `platform = "jimeng"` 录进现有 `sites` + `accounts` 体系（复用 CRUD / 列表 / 状态 UI），但因为它**不是 OpenAI 兼容协议**（火山 V4 HMAC 签名、异步两步生成、无 `/models` 端点），所有 OpenAI 专属路径都为它开了**干净的分支**，绝不污染其它平台：
+
+- **平台判定**：`routes::admin::accounts::is_jimeng_platform(&site.platform)`（大小写不敏感）是唯一事实源；站点 `platform` 字段为自由字符串，无白名单，前端下拉新增 `jimeng` 选项即可。
+- **AK/SK 存法**：AK 落 `accounts.access_token`；SK + region/host/session_token 收进 `extra_config.jimeng.{secretKey,region,host,sessionToken}` JSON。`credentialMode` 强制 `apikey`（只在「API Key 管理」分段出现，永不进 session 分段）。**SK / sessionToken 是机密**：列表 / get / update 响应一律用 `mask_account_extra_config` 替换为 `••••`；带掩码的 `extra_config` 回写会被 `update_account` 拒绝（留空即保留原值）。
+- **验证（签名探测）**：`verify_token` 检测到 jimeng 平台时走 `verify_jimeng_token` → `JimengProvider::from_credentials(ak, sk, region, host, session).verify()`，对 GetResult 发一个哨兵 `task_id` 的最小签名请求。火山网关在业务层之前校验 V4 签名：签名通过 → 业务层报「任务不存在」（即 `Authenticated`）；签名失败 → 网关返回鉴权类 `Code`（`classify_verify_response` 按 `is_auth_error_code` 判定 `AuthFailed`）。**绝不调 `/models`**，绝不触发生成。
+- **不进路由表**：`create_account` 检测 jimeng 后走 `create_jimeng_account`，单条插入、**不** `spawn_route_rebuild`；前端 `handleTokenAdd` 对 jimeng 也跳过 `checkModels` / `rebuildRoutes`。
+- **站点 probe 短路**：`build_probe_plan`（probe-now / probe-stream 共用入口）对 jimeng 直接 `BadRequest`，提示改用连接管理的「验证」做签名连通性检查（逐模型 chat 探测对它无意义）。
+- **运行健康来源**：jimeng 不走 OpenAI 代理通道（独立 `/api/jimeng/*`），`proxy_logs` 无记录，否则永远 `unknown`。改由 `derive_jimeng_runtime_health` 从最近一条 `background_tasks`（`jimeng-image/video-generation`）派生平台级健康（succeeded→healthy / failed→unhealthy / running·pending→进行中 / 无任务→「凭证验证通过后即可使用」），`account_response_value_with_jimeng` 在站点为 jimeng 时用它覆盖 proxy-log 派生值；其它平台传入的 jimeng 健康一律忽略（回归零影响，有断言测试守护）。
+- **前端表单**：`Sites.tsx` 选 jimeng 时预填 URL `https://visual.volcengineapi.com`，隐藏「API 请求地址池」与「刷新后自动探测」；`Accounts.tsx` 在 API Key 分段对 jimeng 改成 AK + SK（必填）+ region/host/session（选填），点「验证 AK/SK 签名」做签名探测，校验通过才能添加。
