A Closed, Parameter-Free Foundation of Fundamental Physics

We show that the Universal Ψ Lagrangian provides a closed, self-consistent, and parameterfreevariational principle from which quantum dynamics, relativistic structure, mass generation,and gauge sectors emerge without external assumptions. We further demonstrate that all majorunification programs of the last four decades fail at least one of the essential requirements of afundamental theory: uniqueness, closure, predictivity, infrared consistency, or internal variationalcoherence. For each failure we provide the explicit correction naturally supplied by the Universal ΨLagrangian.
