Scope

The configuration space may contain arbitrary real lengths and affine isometries. These remain external labels unless a finite code and decoder are supplied. The executable examples cover only declared finite families.

A geometric coupling may be nonlinear in the matter state. Consequently the complete coupled evolution is not generally a quantum channel. Channel locality, no-signalling, distance contraction, and retiming are asserted only for the prescribed channel objects named in their statements.

The four-face construction changes the cellulation of a prescribed slicing of an already fixed spacetime. It is not a new gravitational solution, a particle-supported transition, or an implementation of the full polygon model. No field equation, curvature-convergence theorem, Newtonian limit, or equivalence of matter clocks and propagation cones is proved.
