__N__ commanded action sequences over __R__ start frames, for scoring a tactile world model's rollouts against ground truth that is geometric, not photometric. Nobody performed these motions, so there is no ground-truth future image — what is ground truth is where the sensor would be, and its projection into each camera. Full method and usage in the README; per-probe clips are under /probes/.
