The action representation is optional relative-joint mode. Dimensions
0,1,2,3,4,6,7,8,9,10 are target-minus-current joint positions; gripper
dimensions 5,11 remain absolute. The output transform converts predicted
joint deltas back to absolute robot targets.
The repository includes the model, strict run manifest, exact normalizer, normalizer receipt, source full-checkpoint SHA inventory, and fresh finite-tensor load receipt. The full optimizer/training state remains on the producer and is intentionally not part of this inference artifact.
