The Standard Model of particle physics is one of the most successful theoretical achievements in modern science. It organizes known elementary particles and interactions through the gauge architecture SU(3) x SU(2) x U(1), predicts an extraordinary range of experimental results, and provides the dominant framework for particle-sector law. Yet its success does not imply source completeness. The Standard Model does not derive its fundamental parameters, explain the origin of its gauge-sector structure, account for neutrino mass within its minimal formulation, resolve the strong CP problem, explain matter-antimatter asymmetry, or reconcile naturally with general relativity under singular and extreme gravitational conditions. This paper proposes that these deficiencies share a common source: the Standard Model begins after closure has already occurred. It describes the stable particle-gauge surface of physical law but does not explain the deeper coherence-to-closure cascade from which that surface emerges. We therefore interpret the Standard Model as a surface-closure theory rather than a final source theory. Infratier closure physics is introduced as a candidate source framework. In this approach, gauge symmetries are not treated as primitive assumptions but as differentiated closure regimes. U(1) is interpreted as radiative boundary closure, SU(2) as chiral-torsional infratier closure, and SU(3) as confinement-saturated closure. Particle masses are interpreted as coherence-localization residues; neutrino oscillation as partial-closure propagation; strong CP suppression as a consequence of closure-saturated confinement; matter-antimatter asymmetry as asymmetric closure selection; and the incompatibility between quantum field theory and general relativity as evidence that both are derived ontologies requiring a common pre-metric closure source. The paper contrasts this source-theoretic approach with standard beyond-Standard-Model programs, including supersymmetry, MSSM, NMSSM, string theory, M-theory, extra dimensions, grand-unified theories, and hidden sectors. These frameworks may contain important mathematical and physical insights, but many remain horizontal extensions of the Standard Model rather than vertical derivations of its source. Infratier closure physics seeks not merely to extend the Standard Model, but to recover it from beneath. The central claim is that the Standard Model is not false; it is incomplete in the way a perfect science of ice would remain incomplete without the lake. The ice is real, lawful, measurable, and predictive, but it is not the source of itself. So too the Standard Model may be the frozen gauge-particle surface of a deeper coherence medium. Infratier closure physics asks for the lake, the freezing process, and the closure conditions by which the surface becomes possible.
