# X-043 · The shadow wheel as the dual of PDEP

The canonical wheel rotates the visible node; the shadow wheel rotates the same string under its suppressed-path identity. The two are coupled — rotation of one forces rotation of the other — so behaviour on one path is predictable from the other. Where PDEP measures, the shadow wheel computes.
