 **Gate:** the operator has seen the path and a dry run has completed without a
 guard violation.
 
+**The single-point dry run is built**, in the finger debug screen: 执行动作 sends the
+selected point's *solved pose* to the platform — yaw, then pitch, then table X/Y — and
+does **not** command the press axis, so it cannot reach the sensor. The order is the
+model's own (`R_pitch · R_yaw`), so every intermediate pose is one the operator
+watched in the preview. Before it moves it checks the mapping, the target against the
+P0 limits (millimetres for x/y/z, degrees for yaw/pitch) and the rotary calibration —
+all in `motion/service.py`, so a later caller cannot walk around them — and the drives
+are commanded one at a time, each waiting for the previous to arrive, with a stall or
+an alarm aborting the rest. 停止 next to it is the same command as the strip's
+全部停止; 回初始位 in the rail sends every axis to zero with the press axis first.
