This manuscript examines distance scaling behavior observed in core-collapse supernova remnants using an extended spacetime response framework. The work presents a formal analysis of ejecta propagation under extreme gravitational and temporal conditions, emphasizing the relationship between rapid mass redistribution and subsequent large-scale expansion characteristics. Mathematical formulations are provided to compare classical hydrodynamic expectations with an alternative response-based interpretation. The results demonstrate systematic agreement with observed remnant expansion distances while remaining fully consistent with relativistic constraints. Detailed derivations, parameter values, and internal theoretical structures are intentionally restricted in order to preserve intellectual property and ongoing research development.
