Reproduction Kit (GOLD) for: Conditioning the Dark Energy Equation of State in Planck 2018

This archive provides the frozen, publication-grade reproduction kit (GOLD) for the analysis presented in: “Conditioning the Dark Energy Equation of State in Planck 2018: A Reproducible Support-Restriction Diagnostic in w_0CDM.” The kit contains all materials required to reproduce the numerical results of the EP2 (Planck 2018 FULL likelihood) analysis, including: MCMC chains for all runs (CTRL, CTRL2, restricted-support) Cobaya YAML configuration files and run metadata Jupyter notebooks that regenerate tables and figures Posterior summaries and χ² breakdowns Environment fingerprints (conda / package versions) Scope and validity All runs use the same Planck 2018 likelihood configuration: TTTEEE_lite (Plik) + lowTT + lowEE + CMB lensing. χ² differences are only meaningful within the included run set (CTRL / CTRL2 / restricted-support). This dataset is frozen and should not be modified. Relation to other datasets This GOLD reproduction kit supersedes earlier SILVER / EP1p5 kits and corresponds to the publication-grade analysis. Earlier exploratory kits remain available as separate Zenodo records for historical transparency. The dataset is intended to support full numerical reproducibility and independent verification of the reported results.
