Unlike Dark Matter particle hypotheses, KGC postulates that the effective gravitational acceleration is modulated by an additive cosmic floor (a_floor), governed by the cosmic expansion rate. Applying this framework to the SPARC and KMOS3D datasets, we find that a universal coupling constant alpha = 0.062 describes galactic rotation curves across four orders of magnitude in mass and 10 billion years of cosmic time. In high-quality filtered samples, the model achieves an R-squared of 0.94 and an RMSE of 18.4 km/s. We demonstrate that KGC provides a mechanical resolution to the Genzel Paradox at high redshift through expansion-driven damping of the metric stiffening. Furthermore, we provide a General Covariant formulation (Scalar-Tensor action) that preserves the Strong Equivalence Principle in high-acceleration regimes, ensuring compatibility with Solar System dynamics while resolving the Hubble Tension.
