MEON: A Topologically Selected Effective Spin-Torsion Field Theory in 4D Spacetime

This release presents the MEON framework as a speculative but formally consistent Effective Field Theory (EFT) candidate for selected dark-sector phenomenology in four-dimensional spacetime. The model is built around a topological Fibonacci-Lucas symmetry knot, F4 · L4 = 21, and a corresponding internal spin-Casimir matching condition j(j+1)+1 = 21 for the j = 4 sector. A self-consistent alpha-resonance equation yields a stable macroscopic branch near N ≈ 194.0000436 within the proposed phenomenological integer-lock structure. The theory introduces a massive axial spin-torsion field S_mu coupled to an effective axial current J_5^mu through a Proca-consistent action with metric signature (+,−,−,−). The framework separates dark-sector phenomenology into two proxy components. First, a topological infrared vacuum sector stabilizes the macroscopic D = 4 geometry and allows a residual vacuum offset rho_MEON,0, producing an effective equation of state w_MEON = −1 as a dark-energy-like proxy. Second, local torsion inhomogeneities sourced by compact axial currents provide a Weyl-corrected torsion-lensing proxy that can qualitatively reproduce Bullet-Cluster-like peak shifts in simplified 2D toy simulations. This release does not claim experimental confirmation or a complete replacement of Lambda-CDM. Instead, it provides a compact release-candidate formulation of MEON as an internally structured spin-torsion EFT hypothesis, with explicit open theory gaps. Future work must derive the residual vacuum offset from a UV-complete microscopic theory, establish the astrophysical origin of macroscopic axial currents, solve the full linearized Einstein-torsion lensing system, and fit the model against published weak-lensing mass maps using quantitative chi-square or Bayesian methods.
