 - 新增 `/video` 视频创作台页面，参考生图工作台布局，支持提示词、参考图、视频参数、生成结果、保存素材、下载和本地生成记录；清晰度和秒数均支持常用值选择与手动输入，生成记录只保存媒体 `storageKey` 并可回填本次提示词、参考图和参数。
 - 视频创作台生成前会把模型、尺寸、秒数、清晰度归一化为视频接口支持的参数，并展示后端返回的错误信息，避免页面侧残留的生图参数影响视频请求。
 - 火山方舟 Agent Plan / Seedance 2.0 视频生成需要在真实账号下验证：`/contents/generations/tasks` 创建任务、轮询状态、`content.video_url` 回填画布，以及 401/403/429/超时错误提示。
- `PUBLIC_BASE_URL` 已配置公网域名时，需要验证本地上传参考视频能被火山拉取；未配置或配置为内网地址时，需要验证前端能给出明确提示。
+- 管理后台保存私有渠道后，需要验证所有已启用渠道里的模型会自动出现在公开 `availableModels`，并且 `defaultVideoModel`、`defaultImageModel`、`defaultTextModel` 在为空或失效时会自动修复，前台不再显示旧的 `grok` 默认值。
+- `/video` 和画布视频设置已按 Seedance 2.0 增加分辨率、比例、4-15 秒/智能时长、生成声音和水印参数；需要在真实浏览器里验证参数回填、生成记录和画布节点配置都能保持一致。
+- `/video` 支持最多 9 张参考图、3 个参考视频、3 个参考音频；需要验证格式、大小、音频时长提示和生成请求中的 `reference_image`、`reference_video`、`reference_audio` 组装。
+- 画布新增音频节点，支持上传、拖入、播放、移动、缩放、删除，并可作为上游参考音频参与 Seedance 视频生成；需要验证刷新后本地音频 URL 能恢复。
+- `PUBLIC_BASE_URL` 已配置公网域名时，需要验证本地上传参考视频和参考音频能被火山拉取；未配置或配置为内网地址时，需要验证前端能给出明确提示。
 - Seedance 返回远程视频 URL 但浏览器无法下载为 Blob 时，需要验证视频节点刷新后仍保留远程 URL，并确认上游 URL 有效期限制。
