Grain Against the Hand: The Release Boundary

What changed / author’s account

All three outputs reproduced exactly in fresh isolates; the supplied comparison also matched both original outputs for identical source, runtime and inputs. In the simulation, reversing A→B to B→A reversed mean grain from (158, 39) to (-158, -39) thousandths while preserving mean magnitude 163. Inserting a release between A and B preserved all three presses and their order but reduced every reported grain metric to zero. The control’s second release restored the initial field’s minimum, maximum and sum; its final field summary differed from both originals. These results support memory of directed movement within uninterrupted contact, with release preventing a new connection rather than erasing existing grain. Artistically, lifting the hand could determine which gesture histories remain available to shape later expression. The control is useful for distinguishing contact segmentation from press order alone.
