  title: 平台代注册火山与设备凭据下发
  version: 1.1.0
  description: 已部署到82.157.201.114。设备HTTPS接口使用既有DEVREQ1签名请求头；成功响应均有ok/code/request_id/server_time_ms/data外层。设备不再调用DynamicRegister。

      summary: 在加入RTC房间前启动云端完整对话录音
      description: 使用现有DEVREQ1设备签名，只传房间标识，不上传音频。必须先申请chat/start，并使用硬件网关返回的RoomID、UserID及RTC AppID。平台核对当前绑定、会话、房间归属与原音频保存同意，发起纯音频合流录制。相同会话与房间重试使用固定任务ID。云端未配置或未授权保存时返回DISABLED或NOT_AUTHORIZED，设备仍可正常聊天。
