Empirical Falsification Tests of Identity Persistence in Discrete Physical Systems

This preprint presents an empirical falsification program for identity persistence in discrete physical systems. Using the standard map as a representative nonlinear dynamical system, the study tests whether identity can persist under progressively adversarial violations of update structure. Four regimes are examined: baseline dynamics, dissipative modification, discontinuous teleportation, and externally enforced relocking. Identity persistence is operationalized through three independent criteria: bounded momentum drift, rotational coherence, and spectral entropy. Ensemble simulations show that identity persists only within admissible update corridors defined by the intrinsic dynamics and collapses under discontinuous violations unless external constraints are imposed. Apparent stability under forced relocking is shown to arise from projection onto an imposed constraint manifold rather than intrinsic persistence. The work is framed as an empirical falsification attempt of the Conditional Unlocking Fields (CUF) hypothesis and provides a reproducible protocol for testing identity persistence in discrete dynamical systems. This preprint has not undergone peer review and is intended to establish priority and enable open scientific evaluation.
