MEON: Topologically Selected Effective Spin-Torsion Field Theory in 4D Spacetime (Version R169 / Audit M021)

This document formulates the MEON framework as a mathematically closed, effective topological spin-torsion field theory in a 4-dimensional spacetime. With the successful completion of the analytical code audits up to Version R169 (Audit M021), the model makes the fundamental transition from an empirical curve-fitting approach to a self-contained, consistent Effective Field Theory (EFT). The central parameters—the four-dimensional topology (D=4), the spin sector (j=4), and the integer resonance number (N=194) —are derived purely geometrically via a Fibonacci-Lucas closure identity and physically locked via the fine-structure constant (). Alongside the mathematical consistency and ghost-freedom of the action, the phenomenological relevance of the field equations is demonstrated through the astrophysical stress test of the Bullet Cluster, as the torsion field couples collisionlessly to the compactness of the galactic cores. The formal microscopic derivation of this effective field theory from the first principles of fundamental quantum gravity is explicitly declared as a remaining open research question (Theory Gap).
