Drag to orbit · wheel to zoom
The same coordinate state that drives the solver now directly places all 54 stickers in three-dimensional space.
A clean-room cube engine built as a comparison point beside the preserved early versions. Every visible sticker has a 3D coordinate and normal vector; turns rotate the actual cube state rather than swapping painted squares. Scramble it, orbit it, play it, then ask the artifact to retrace its own history home.
