Reproducibility package for: "The dark-matter phase boundary as an observable: break amplitude, the cross-galaxy locus, and a forecast for its detection"

This archive contains the complete reproducibility package accompanying the manuscript "The dark-matter phase boundary as an observable: break amplitude, the cross-galaxy locus, and a forecast for its detection." It includes the source code, numerical scripts, figure-generation routines, machine-readable output files, and documentation required to reproduce all analytic calculations, mock-catalog simulations, figures, and numerical results reported in the manuscript. No observational data are included; all results are derived from analytic theory and synthetic datasets generated by the supplied software. The archive is released under the MIT License.
