This paper presents the Quantum Entanglement Spacetime Theory (QuEST), in which spacetime is modeled as a finite‑valence hypergraph whose dynamics are governed by entanglement growth subject to a universal area–entropy constraint. Developed through AI‑assisted iteration, QuEST recovers general relativity in the classical limit and makes testable predictions such as modified graviton dispersion, parity‑odd CMB patterns, and black‑hole echoes, while adhering to background independence, holographic finiteness, and empirical minimality.
