左臂换成 tool10120938 后，手眼仍按旧 tool1 和 8×11 板求解，顶视迁臂又按短跳 rest-to-rest，真机上要么整体偏一截，要么中途弹射启停。

眼在手上改用该 TCP 做 AX=XB，再折回相机→法兰；A5 内角点改为 11×8，09-04 / 10-09 旧结果留在 backup。一阶段 D435 迁臂改成一条 FollowJointTrajectory（余弦加减速，近处降速，XY 进门槛后再单独收垂直），跟踪锁高与悬停齐平，避免倾斜相机下先降一截把孔位重投影偏掉。--no-descent 只降到离面 15 mm；跳过三阶段时触觉 USB 打不开不再空等几分钟。
