Lattice Walker Flip Clock Retardation from Arithmetic Field Structure

In this note we build a bridge between DIG/ICL arithmetic field structure and the endogenous flip clock of a self-interacting lattice walker. Frozen fields extracted from a representative ICL locking jump are coupled into the walker’s pre-move decision field in two ways: a global scalar channel derived from the overlap mass Q, and a localized defect channel ΔA = A₊ − A₋ built from the field difference across the jump. We find that the global channel shifts the threshold for the single-flip branch at fixed walker coupling, while the localized defect retards the clock by delaying re-entry into the same UTURN–STRAIGHT frontier. These results provide a concrete mechanism by which global arithmetic field structure can be read out locally in the walker’s event-selection dynamics.
