Branch Opening and Regime Architecture in a Covariant Scalar-Tensor Framework

This record contains the Appendix G reproducibility package for the manuscript Branch Opening and Regime Architecture in a Covariant Scalar-Tensor Framework. The package provides the CSV tables, Python scripts, README files, requirements files, and validation reports used to reproduce the fixed harmonic galaxy-readout tests in Appendix G. These tests evaluate a fixed branch-support acceleration response on SPARC and Sofue rotation-curve archive inputs and compare it with the direct Newtonian baryonic proxy and a fixed-scale RAR benchmark. The harmonic response is treated as a fixed observational readout of the branch-opening framework, not as a galaxy-by-galaxy fitted halo model. The package documents the SPARC internal readout, the Sofue external transfer, per-galaxy diagnostics, threshold counts, and information-criteria summaries.
