Description (for Additional Information) Deposit Description: This repository contains the preprint and reproducibility artifacts for the reassessment of the Universal Entropic Mass Principle (UEMP). Main Document: A PDF detailing the transition of the UEMP from a variational/selective hypothesis to a strictly operational constraint. Methodology: Analysis based on the SPARC database of 175 disk galaxies to test RAR residuals against internal and environmental properties. Null Tests: Includes supplementary data and figures showing the structural independence of the acceleration scale and the absence of radial or environmental trends in RAR residuals. High-Redshift Constraints: Comparison of predicted cosmological scaling against currently available high-z kinematic data. Reproducibility: All analysis scripts and data proxies are included to ensure transparency and allow for independent validation of the radial and environmental tests presented.

We present a critical reassessment of the Universal Entropic Mass Principle (UEMP) through a structured program of falsification tests. Low-redshift galaxy dynamics confirm the empirical universality and radial consistency of the characteristic acceleration scale. Environmental and internal consistency tests show no evidence for adaptive or selective behavior. High-redshift constraints disfavor a strong cosmological scaling of the entropic parameters. Motivated by these results, we reformulate the UEMP in a minimal and unambiguous operational form, in which entropy acts solely as a local dynamical constraint rather than as a selection or optimization principle.
