R-layer Mode Theory (RLMT) LXIV: R-layer Quantum Gravity and Wheeler–DeWitt Dynamics

This volume develops the quantum-gravitational foundation of R-layer Mode Theory. It derives strict R-layer Einstein equations, constructs the R-layer Wheeler–DeWitt equation, and formulates canonical quantization for geometry and tension fields. The resulting framework connects R-layer mode hierarchy, black hole interior dynamics, islands, and cosmological tensor modes within a unified quantum gravity structure.
