This second version extends the homogeneous compression framework by introducing emergent gauge structure from internal degrees of freedom of locally shared compression nuclei. In Version 1, spacetime curvature and Einstein field equations were shown to emerge from a scalar compression field interpreted as internal diminution. In the present development, we demonstrate that internal phase orientation of compression nuclei naturally gives rise to U(1) gauge symmetry. The electromagnetic potential is identified with the connection associated with local phase transformations, and Maxwell’s equations emerge from the corresponding curvature structure. Furthermore, we outline how multi-component internal structure of compression nuclei can generate non-Abelian gauge sectors, reproducing the mathematical structure of Yang–Mills theories. This establishes a unified conceptual architecture in which gravitation and gauge interactions arise from different structural aspects of a shared compression-based internal geometry. The work remains theoretical and foundational in scope.
