The discrepancy between observed galaxy rotation curves and the predictions of Newtonian dynamics based solely on baryonic matter remains a central challenge in galactic astrophysics. While dark matter halos and modified gravity theories have been widely explored, persistent empirical regularities suggest that additional effective mechanisms may be at play in rotationally supported disk galaxies. In this work, we present the Macroverse framework, a phenomenological and non-local effective dynamical model designed to describe galaxy rotation curves without introducing new particles or modifying local gravitational laws. The framework supplements Newtonian gravity with a weak, scale-dependent correction modulated by the global rotational state of the disk. This correction is constructed to preserve energy conservation, remain negligible at small radii, and activate smoothly in the outer regions of rotationally coherent systems. We test the model using a systematic analysis of the SPARC (Spitzer Photometry and Accurate Rotation Curves) database. From the 171 galaxies available, 107 systems with sufficient radial sampling are analyzed. A grid-based fitting procedure is employed to explore the model parameters and assess statistical performance across the sample. The results show that the Macroverse framework provides good or acceptable fits for a substantial fraction of disk galaxies, particularly those that are dynamically cold and disk-dominated. Parameter distributions exhibit non-random clustering, and the quality of fits correlates strongly with rotational coherence. Conversely, the model performs poorly in galaxies with strong bulges, bars, or complex non-circular dynamics, consistent with its intended domain of applicability. We emphasize that the Macroverse framework is not proposed as a universal alternative to dark matter or modified gravity, but as a complementary, empirically testable effective description applicable to a specific dynamical regime. Its predictive behavior, explicit limitations, and falsifiability are discussed in detail. The results highlight the potential role of large-scale rotational organization as an effective dynamical ingredient in galactic systems.
