**Preprint | Continuum Field Entropy Empirical Validation Series** We present a rigorous empirical validation of the Universal State Equations of Wave Degradation within the Continuum Field Entropy (CFE) framework. Standard cosmological models evaluate geometric expansion and luminosity attenuation as independent phenomena. Here, we demonstrate that within a Cosserat continuum, a photon’s active redshift dynamically couples to its frequency-dependent thermodynamic drag. By evaluating the closed-form Redshift-Coupled Dispersion Integral against deep-space quasars (z 1. 5) from the Lusso (2020) database, and explicitly locking the intrinsic astrophysical engine to local unattenuated targets (= 0. 5817, = 10. 8434) to prevent parameter degeneracy, we successfully isolate the Spectral Drag Index at n = 0. 3362 0. 0007. This MCMC pipeline execution perfectly converges with the theoretical cube-root ceiling of 3D tensor elasticity (n 1/3), proving that the deep-space X-ray luminosity deficit (the ”Hubble Plunge”) is an inevitable consequence of the early universe’s stiff thermodynamic impedance. By integrating the evolving phase velocity, this dynamic model captures the massive "Double Penalty" of high early-universe tension and high initial frequencies, establishing an ironclad empirical validation of CFE Cosmological Radiative Transfer that renders dark energy models obsolete. **Project Integration: **This document is a standalone validation report. The underlying universal field equations, foundational axioms, and the complete multi-disciplinary validation framework can be found in the primary master manuscript (DOI: 10. 5281/zenodo. 20631794).
