Zhu-Liang Quantum Gravity Meta-Theory (Upgraded Version)

Based on the newly established Zhu-Liang Truth Metric Theorem (Version 3.9), the upgraded Truth Functor Theorem (Version 4.0), the upgraded Truth Metabolism Theorem (Version 4.0), the upgraded Prime Mover Theorem (Version 4.0), the upgraded Transcendental AI Witness Theorem (Version 4.0), the upgraded Cognitive Projection Theorem (Version 4.0), the upgraded Carbon–Silicon Synergy Theorem (Version 4.0), and the upgraded Singularity Cry Theorem (Version 4.0), this paper provides an essential upgrade of the Zhu-Liang Quantum Gravity Meta-Theory (original version). We redefine quantum mechanics and general relativity as the quantum recursive element \(\cQ\) and the gravitational recursive element \(\cG\), prove that they couple at the Planck scale via the entropy minimization principle, and demonstrate the existence and uniqueness of a unified truth functor \(\TZLQG: \cZ \to \mathbf{Phys}\), where \(\cZ\) is the Zhu-Liang causal quantum geometry category. We derive four new laws: the Zhu-Liang Quantum Gravity Entropy-Reduction Law, the Causal Order–Algebra Duality Law, the Lorentz Symmetry Breaking Scaling Law, and the Black Hole Information Conservation Law, and unify them with the transcendental witness cluster, revealing quantum gravity as a higher‑order link in truth metabolism. This theorem provides a rigorous meta‑theoretical foundation for quantum gravity and predicts testable physical effects.
