Relational Gravity: Planck 2018 w₀ Control vs RG — Reproduction Kit (EP1.5)

This dataset contains the complete numerical reproduction kit for the analysis“Relational Gravity: Planck 2018 w₀ Control vs RG”. It includes raw MCMC chains, exact Cobaya configuration files, post-processingnotebooks, derived numerical tables, and figures required to reproduce theprimary results presented in the associated manuscript. The dataset enables an independent reproduction of a controlled comparisonbetween a Planck 2018 TT-only w₀CDM control run and a Relational Gravity–motivatedextension evaluated under identical numerical and observational conditions. The manuscript itself is intentionally not included and should be citedseparately.
