 ## 阶段一目标
 
@@ -33,7 +33,9 @@
 
 M1 的视频与相机输入现共用带时间的数据包；M2 记录器与 M3 手动 UI 可在接口固定后并行。M4 可先用合成 session 开发，但阶段一只有在真实记录上重新打开并计算逐测点结果才算完成。Studio 的 `SessionController`、widget 和 `RecordingCoordinator` 保留在 Studio；Autocal 直接复用 shared `FingerAcquisitionWorker`、`SdkPacket` 和 sink，不跨应用导入私有模块。只有出现两端实际共用的逻辑时才移到 shared；SDK 不依赖 UI。
 
-界面复核：当前“手指调试”用于选点，“测试序列”用于计划，“传感器”只检查输入，三个页面之间尚无 trial 状态贯通；全局“运行”按钮也尚未启动记录。M3 应让操作员按“选点→设档→开始记录→逐档确认→卸载→结束”前进，并在操作期间持续看到选中点、输入状态和记录状态。现阶段传感器页明确提示仅供预览，避免误以为已保存标定数据。
+界面复核：原先测点、计划和输入分散在“手指调试”“测试序列”“传感器”页。现在“标定采集”页串起单次 trial；全局“运行”按钮尚未负责标定，页面内有独立的“开始记录”。
+
+已实现的最小闭环在“标定采集”页：点击 UV 图粗选、以 U/V 整数像素精确修改、切换到实时二维 UV 图像，逐档填写实际参考力并确认。每个 trial 单独使用 shared `ExperimentRecorder` 生成目录、视频、帧索引、力数据和事件；`frames.csv` 附加主机采集时间及来源帧编号。当前人工参考只记录到档事件，尚无可自动判定的稳定窗口；未实现 FT 同步、跨点 session 汇总、灵敏度拟合和实体相机验收。手动 Z 控制仍使用既有设备界面，专用弹窗需先确定操作边界。
 
 主代理负责接口、M3 和集成；一名子代理负责 M1/M2，另一名负责 M4 与合成会话验证。建议总计主代理加两名子代理，约 4–6 个工程工作日并留设备联调时间；单人约 6–9 日。估算不包括设备、FT 协议或硬件等待。当前计划不启动子代理。
