 ## 界面说明
 
 - **链路 1**：只需填 `camera_ids` 与耗材候选，点「开始手术」；**无需上传视频**（服务端自动 RTSP 拉流切片）。
-- **链路 1 / 3 共用「步骤 2 · 耗材候选」**：标签区显示「编号 + 名称」；提交时以 `{"消耗品编号","名称"}` 对象数组发送（与医院导出表一致）。
+- **链路 3**：独立 MP4 上传区；与链路 1 **互斥**——同一手术号若仍有实时开录，离线上传会被拒绝；页面会提示先「结束手术」或换号。
-- 误把 `.mp4` 路径填进耗材候选时，页面会提示并阻止提交。
+- **模式记忆**：上次选择的链路会保存在浏览器 localStorage；默认首次打开为链路 3。
