This work extends AM Field Theory (VI) into its complete tensorial 3 + 1 formulation, unifying curvature, energy, and phase coherence within a single deterministic field Ψ_AM coupled self-consistently to the curvature-coherence tensor Λ_{μν}. Six GPU-accelerated lattice simulations confirm exact energy conservation (ΔE/E₀ < 10⁻³), phase-coherence stability (Cφ > 0.99), and curvature boundedness through resonance-feedback saturation, eliminating singularities and information loss. The tensorial AMFT system reproduces the Hawking-temperature relation (T_H ∝ 1/M), satisfies the Averaged Null Energy Condition, and establishes a deterministic, time-reversible description of spacetime dynamics.
