Curvature as Non-uniformity of Time Flow Density: Reconstructing Gravitational Geometry from Unified Time Scale \kappa(\omega)

General relativity attributes gravitational phenomena to spacetime curvature, while in special relativity and quantum theory time often appears as an external parameter or local ``proper time'', creating a long-standing conceptual divide. In this paper, within the framework of unified time scale and information rate conservation, we propose and systematically demonstrate the following perspective: geometric curvature can in essence be rewritten as non-uniformity of ``time flow density'' field \k
