This paper extends the Universal Metric Mismatch (UMM v9.5) computational framework to resolve the historical problem of anomalous planetary orbit precession, specifically the perihelion shift of Mercury, without invoking the metric tensors of Einsteinian General Relativity. Within the rigid, discrete Hexagonal Close-Packed (3HCP) matrix, a moving macro-body is modeled as a cascading wave-packet of volume-charge displacement. The study demonstrates that intense hydrostatic pressure surrounding a central mass compresses coordination shells, altering the localized execution clock-tick (dt) of the spatial matrix. By calculating trajectories through finite-difference lattice stress divergence, the classic orbital precession value is derived entirely from hardware-level discrete grid mechanics.
