Matter-Space Coupling Framework (MSCF) Numerical Suite

This is the public release of the computational repository for the Matter-Space Coupling Framework (MSCF). This suite contains the source code, data pipelines, and validation scripts supporting the following publications: 1. Theory Paper: Matter-Space Coupling Framework: Deriving General Relativity as the IR Limit of Causal Substrate Dynamics (2026). Scope: Reproduces the cosmological transfer functions, 2x2 eigenvalue crossovers, and remnant cross-section analysis. 2. Search Paper: Are Black Hole Horizons Classical? A Parameter-Free Echo Search in LIGO O1-O3 (2026). Scope: Contains the complete mscf_derived_echo pipeline, including the parameter-free template generator, Regge-Wheeler greybody solver, and the LIGO matched-filter/cepstral search scripts. This release includes all Python scripts, Jupyter notebooks, and precomputed data required to reproduce the figures and tables in both manuscripts.
