Unified Residual Classicality Criterion for the Quantum-to-Classical Transition

This record archives version v1.2 of the manuscript "Unified Residual Classicality Criterion for the Quantum-to-Classical Transition" and its supplementary validation package. The work proposes a falsifiable, comparator-dependent residual-vector criterion for assessing quantum-to-classical behaviour. Classicality is certified only when predeclared residual channels - dynamical, semiclassical, operational, coarse-graining, and open-system - simultaneously pass their declared tolerances for a specified comparator, observable class, resolution, norm, and finite time interval. The archive includes the manuscript, supplementary mathematical notes, a supplementary validation report, figures in PNG/PDF/SVG, benchmark CSV files, and Python scripts for reproducing the figures and validation tables. The work does not claim a universal solution to the measurement problem or a universal proof of quantum-to-classical emergence; it provides a finite-time certification framework with sufficient error-control conditions and controlled benchmark validation.
