Recent cosmological observations present two critical, seemingly unrelated anomalies: the unexplained early accretion of Supermassive Black Holes (SMBHs) at z > 10 detected by JWST, and the persistent Hubble tension (H₀). In this work, we propose the PMY (Primordial Metric Yielding) model, a purely geometric and covariant framework that simultaneously resolves both crises by extending the formalism of General Relativity. We hypothesize that the spacetime metric possesses an elastic yield limit with respect to the energy-momentum tensor. The resulting dynamics lower the primordial comoving sound horizon, reconciling H₀, generate a hyper-gravity phase that evades the Eddington limit for primordial SMBHs, and induce a geometric mass inflation upon metric relaxation. The model preserves the late universe, avoiding the S₈ tension, and proposes specific falsifiable signatures.
