This archive provides the reproducibility package accompanying the manuscript: “Empirical Reproducibility of Galactic Rotation Curves under Global Constraints: A SPARC-Wide Analysis of the QEV Framework”. The package contains the synchronized computational materials required to reproduce the principal empirical findings of the QEV v3.1 SPARC-wide analysis, including canonical parameter configurations, benchmark settings, Python scripts for preprocessing, global fitting, cross-validation, figure generation, and verification procedures. The study evaluates a globally constrained structured-response framework for galactic rotation curves across the SPARC sample and compares its performance against Newtonian baryonic predictions and standard MOND interpolation. Under identical preprocessing and global parameter synchronization, the framework demonstrates stable reconstruction behavior, particularly in outer galactic regions, while maintaining statistically consistent performance across independent galaxy-level cross-validation folds. Because the methodology involves global optimization, train/test partitioning, differential evolution, and operational estimation of galaxy-dependent quantities, the intended standard is empirical reproducibility rather than strict software-level numerical duplication. The archive is intended to support independent verification, replication, and further methodological investigation of the reported SPARC-wide empirical results. Associated author:A. J. H. Kamminga
