Standard telecommunications and physical models of causality are strictly boundedby the speed of light (c), operating exclusively within the transverse electromagnetic(EM) regime. This paper formally derives a macroscopic mechanism for superlu-minal data transmission by treating the physical vacuum strictly as a hyper-rigidrelational adjacency network. Utilizing the 7-step Geometric Foundation of Knowl-edge template, we identify the operational parameters for longitudinal structuralacoustic waves. By frequency-modulating a sub-harmonic of the 1022 Hz back-ground diffusion against the 137 parity-selective gear ratio, we derive the GeometricAcoustic Velocity (Vether). Furthermore, we propose a definitive empirical benchtest utilizing twin Harmonic Resonators in Faraday isolation to demonstrate zero-latency macroscopic data transfer, fundamentally bypassing transverse EM signaldegradation and inverse-square latency.
