This paper develops a complete, self-contained formulation of gauge-induced gravity using the Adler–Zee spectral representation. It establishes a vanishing theorem for gauge-induced contributions, computes the Standard-Model term with updated lattice inputs, and identifies the classes of hidden confining sectors capable of generating the observed Planck scale. All derivations are provided in a comprehensive appendix, and the framework yields concrete, falsifiable predictions for small variations in Newton’s constant. The work is clear, technically consistent, and relevant to research on induced gravity and hidden gauge sectors.
