We complete the derivation of the Dirac equation from the discrete dynamics of plaquette defects on the internal SU(2) tensor network. The Clifford algebra emerges from the three mutually non-planar hopping paths on the Paley-9 graph, with the number of spatial dimensions fixed by the information-cost minimization theorem. We analyze the GUT-scale phase transition from first principles via the product graph spectrum, proving its first-order nature is robust. The instanton geometric factor on the Ramanujan-18 graph is computed as 1.769 from the complete spectral sum. The Wilson loop threshold correction coefficients are derived as (1/2, 1/3, 1/6) directly from the internal dimensions of the factor graphs, closing the last technical gap in the framework.
