Geometric synthesis embedding Pharis E. Williams’ Dynamic Theory (mass density as fifth coordinate, 5×5 gauge tensor, seven Maxwell-type equations) into the Tau v4. 0 Mathematical Substrate on R3×S1 R³ S¹ R3×S1 with Tav topology (τ=7 h−1 = 7\, h^-1 τ=7h−1 Mpc). The unified 5D action recovers all local results of the Dynamic Theory while delivering zero-parameter cosmology (Casimir dark energy w=−1 w=-1 w=−1, ΩDM: ΩDE=5: 1 DM: DE=5: 1 ΩDM: ΩDE=5: 1, 142857 mode, Hubble/S8 S₈ S8 resolutions). Includes falsifiable Rubin LSST predictions and the Tau Resonator concept at 21. 83 GHz.
