Dirac Equation as the Linearization of Substrate Torsion Dynamics

This paper demonstrates that the Dirac equation arises as a linearized projection of torsion dynamics in the MID substrate. Within the MID/QC framework, spinor behavior, mass terms, and phase evolution are shown to emerge from rank‑3 torsional oscillations and coherence‑field geometry rather than from fundamental quantum postulates. The model reframes the Dirac operator as an effective, low‑order approximation of deeper substrate processes, with spin, chirality, and relativistic structure appearing as boundary‑level manifestations of torsion‑mode coupling. This approach unifies quantum behavior with substrate mechanics, eliminates the need for intrinsic particle properties, and provides a physically grounded mechanism for mass, phase, and spinor evolution. The result is a coherent upstream explanation for the Dirac equation and a substrate‑level foundation for quantum field behavior.
