Theory of Everything – Spectral Formulation Based on the Sansone Model

This Version represents the finalized and peer-review-ready update of the work “Spectral Model for Unification via the Zeta Operator Framework.” It includes the formalization of the spectral realization theorem with rigorous domain and self-adjointness conditions.The functional equation of the Riemann zeta function is explicitly included as Equation (2) in the spectral framework.A new Appendix is added, presenting a numerical simulation of the spectral potential Vζ(t)V_\zeta(t)Vζ(t), constructed from the first 30 nontrivial zeros.
