Figure ablation: Index pretraining lifts robot zero-shot success from 8% to 56%

Figure's Corey Lynch shows predictable scaling for Helix: doubling Index data improved next-action prediction enough to forecast the largest run's loss to four decimal places before training. A key ablation — same model, data, and eval — shows Index pretraining boosts zero-shot success from 8% to 56%, directly transferring whole-body behaviors.
