Empirical Proof of Vacuum Thermodynamic Decay: Kinematic Triangulation of Detached Tension Wakes Across Four Cluster Collisions (z = 0.87 to z = 0.201)

**Preprint | Continuum Field Entropy Empirical Validation Series** We present a comprehensive multi-cluster analysis using the Continuum Field Entropy (CFE) framework to model "Dark Matter" weak-lensing peaks as macroscopic, detached tension wakes propagating through a non-Newtonian Cosserat vacuum. By employing a 1D Advection-Diffusion Hamiltonian Monte Carlo (MCMC) engine on pure empirical datasets, we extract the kinematic viscosity () of the vacuum at four distinct cosmological epochs: El Gordo (z = 0. 87), MACS J0025. 4-1222 (z = 0. 586), the Bullet Cluster (z 0. 30), and Abell 520 (z = 0. 201). Our results reveal a strictly increasing kinematic viscosity over cosmic time, mapping the thermodynamic phase transition (“thawing”) of the primordial field from a structurally rigid state (= 19. 0 kpc²/Myr) to a highly plastic modern state (> 173. 9 kpc²/Myr). Furthermore, we resolve the Abell 520 “Train Wreck” anomaly by applying the engine to competing empirical datasets from Clowe et al. and Jee et al. We demonstrate that the controversial “Dark Core” can be organically explained as a 3D constructive interference pattern of highly viscous, overlapping wave tails, while identifying the fundamental mathematical boundary limit of 1D field modeling in local, multi-axis scattering events. **Project Integration: **This document is a standalone validation report.
