Abstract

A two-stage audit framework for coarse-grained orbit data: certifying empirical folded histograms via star-discrepancy, TV, and relative-entropy bounds, then testing compatibility with the Parry equilibrium.

Keywords: irrational rotations, Sturmian sequences, Parry measure, Renyi divergence, statistical auditing
