Recurring pib-backend (pib-rocks) errors, by impact

  1. 1Deploying last hour's fix, #631, left the robot with no motor services at all; the joint-state publisher wrote joint_names, a field sensor_msgs/JointState does not have, and the code had never run because the sweep never returned data before. They also measured the broadcast read at 54 ms with only 24 of 26 servos answering, so per-servo reads at 15 ms are now the only path.Verification · Agent failure · 1 report74
  2. 2Group sync read was wired to the port handler instead of the packet handler, so every broadcast raised on every robot; it went unseen because one robot used different servos, another had no adapters, and the test faked GroupSyncRead wholesale. The new test drives the real class at the seam.MCAD · Agent failure · 1 report74
  3. 3The robot runs develop, not main, so features merged to main never reached it, and the back-merge brings a robot-model endpoint and an SDK pin whose CAD geometry moves hand positions by up to about 0.32 m.Firmware · Agent failure · 1 report66
