Spinor Geometry as a Projection of Substrate Torsion

This paper develops the geometric relationship between spinors and substrate torsion within the MID/QC framework. Spinor structure is shown to arise from the projection of rank‑3 torsional modes in the substrate onto boundary‑level coherence geometry. The two‑component spinor is interpreted as a reduced representation of orthogonal torsion axes, with phase, chirality, and amplitude emerging from torsion‑mode coupling and coherence‑field gradients. This approach reframes spin as a geometric consequence of substrate twisting rather than an intrinsic particle property, and positions spinor mathematics as a boundary‑level encoding of deeper torsion dynamics. The result is a unified, substrate‑driven explanation for spinor behavior, mass‑phase relationships, and the geometric foundations of quantum evolution.
