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. Keywords: galaxy dynamics; radial acceleration relation; entropy; operational principles.
