We propose a unified theoretical framework, the Stabilized Angular Torsion (TAS) model, which interprets the gravitational constant $G$ as an emergent property of a discrete vacuum lattice (Quantum Resonance Domain). By introducing a supraluminal phase velocity $\vOTA = 10^{20}c$, we demonstrate that flyby anomalies and galaxy rotation curves share a common topological origin. The model predicts a specific metric transition threshold at $1.03$~AU, corresponding to the saturation of the lattice's surface anchoring area.
