Every step predicts a number, then measures it

A robot arm that states what its sensors should read before it moves, then checks whether they did. A camera can be fooled by an arm in the way. A load cell cannot be talked into believing a grasp that never happened.

Everything on this page is a recording of a real execution — captured frames, measured numbers, nothing staged. These runs were planned by a language model, which is what they show that the live simulator cannot.
