The Parameter-Free Cl(8) Universe: Cosmological Observables and Fundamental Couplings in Time-Unity Theory

We present Time-Unity Theory (TUM), a geometric framework where dark energy and dark matter emerge from a single Cl(8) torsion field. From Bianchi identities and matter conservation we derive a topological invariant Geff(z)Λeff(z) = G0Λ0. This law predicts deviations in H(z) and in the linear growth factor D(z) at 2 < z < 5. At galactic scales, torsion condensates locally enhance G, providing a mechanism for early structure formation and cosmic voids without new particles.
