Reproducible Freeze-Out Pipeline for CETΩ vs ΛCDM Expansion Tests

fully reproducible numerical pipeline used to generate the grids, tables, and figures for the study: “Differential Cosmological Signatures of CETΩ vs ΛCDM in Thermal Freeze-Out”. The pipeline implements comparative freeze-out calculations under: • standard ΛCDM radiation-era expansion • CETΩ modified expansion history • parameter grid scans in (m_DM, λ_SH) • alpha_log stability scans • morphology proxy normalization maps It includes: • scan drivers • table builders • gnuplot figure generators • reproducibility scripts • frozen grid outputs used in the publication This deposit corresponds to the exact frozen pipeline version used to produce the published results and figures. It is intended for reproducibility and verification purposes. Main components: scripts/ — scan and plotting drivers grids/ — numerical scan outputs figures/ — generated paper figures morphology/ — morphology proxy module Environment requirements: bash + gnuplot + standard Unix tools.
