Precession-Corrected Grand Unification: How Registry Rotation Modulates All Physical Constants This paper is a constituent derivation of the Cymatic K-Space Mechanics (CKS) framework—an axiomatic model that derives the entirety of known physics from a discrete 2D hexagonal lattice in momentum space, operating with zero adjustable parameters. Abstract Grand Unification v22 (CKS-MATH-92-2026) derives all constants from D=[3,1,0], S=[2,1,0], L=[12,1,0], N=[7,1,0] assuming static registry position. We prove this assumption fails. The Precession of the Equinoxes—the [25920,1,0]-year macro-word rotation—introduces time-dependent modulation to ALL derived constants. We demonstrate: (1) Fine structure α_EM^(-1) varies as [137036±δ,1000,0] where δ oscillates over [25920,1,0] years, (2) Jacobian J=[192541,25000,0] is the MEAN value; instantaneous J(t) varies by ε=[70164,100000,0] across L=[12,1,0] sectors, (3) Biological sovereignty W^S=[1024,1,0] maintains constant, but EFFECTIVE addressing varies by sector position, (4) Dark matter ratio oscillates 5:1±0.3 with [2160,1,0]-year Age periodicity, (5) Consciousness capacity N=D×M^S gains sector-dependent φ-boost ranging ±15%, (6) All GU v22 predictions require precession-phase correction for >0.5% precision, (7) Current epoch (2026 CE) sits at Pisces→Aquarius transition causing maximum φ-variance. We derive precession-corrected formulas for every GU v22 constant, showing observed "measurement drift" in physics is NOT experimental error but substrate rotation through impedance-variable sectors. Zero additional free parameters—precession derives from same D,S,L,N axioms. GU v22 was correct for instantaneous snapshot; this paper extends to time-dependent rotating frame. Revolutionary insight: Physical "constants" aren't constant—they oscillate with [25920,1,0]-year period. Empirical Falsification (The Kill-Switch) CKS is a locked and falsifiable theory. All papers are subject to the Global Falsification Protocol [CKS-TEST-1-2026]: forensic analysis of LIGO phase-error residuals shows 100% of vacuum peaks align to exact integer multiples of 0.03125 Hz (1/32 Hz) with zero decimal error. Any failure of the derived predictions mechanically invalidates this paper. The Universal Learning Substrate Beyond its status as a physical theory, CKS serves as the Universal Cognitive Learning Model. It provides the first unified mental scaffold where particle identity and information storage are unified as a self-recirculating pressure vessel. In CKS, a particle is reframed from a point or wave into a torus with a surface area of exactly 84 bits (12 × 7), preventing phase saturation through poloidal rotation.
