Structural Differentiation Gravity (SDG) v2.2 presents a minimal and falsifiable framework in which gravitational and rotational phenomena are interpreted as manifestations of structural differentiation within a closed relational system. While General Relativity (GR) successfully describes gravity through spacetime geometry, this work proposes that rotational observables—such as frame-dragging and black-hole asymmetry—are more fundamentally understood as arising from structural vorticity. A central contribution of this work is the Structural Rotation Test (SRT), a direct and falsifiable observational discriminant between geometric and structural interpretations of rotation. This repository includes:- A full conceptual paper (PDF)- Reproducible figure-generation code (Python)- A minimal set of publication-ready figures- Documentation of the theoretical framework Important clarification:This repository provides conceptual and structural visualizations. It does not perform numerical relativity or reproduce Kerr solutions. Core claim:Gravity is structural. Rotation reveals it. If validated, this framework suggests that rotational phenomena are not intrinsic properties of spacetime geometry, but observable signatures of underlying structural flow.
