FCLET Hubble-Tension Combined-Likelihood Reproducibility Dataset: Planck 2018, DESI DR2 BAO, and Pantheon+SH0ES

This dataset contains the final successful andreproducibility-relevant artifacts for the FCLET combined-likelihoodHubble-tension analysis using Planck 2018, DESI DR2 BAO, andPantheon+SH0ES. The nuisance-marginalized production consists of four FCLET chains and fourmatched LambdaCDM chains. The FCLET posterior givesq_fclet = 0.930560 ± 0.012713and H0_proxy = 73.7127 ± 0.9752km s^-1 Mpc^-1, corresponding to a residual local-H0 inconsistency of0.472sigma. The matched LambdaCDM result is H0 =68.9637 ± 0.2681km s^-1 Mpc^-1, with a residual inconsistency of3.795sigma. The corrected dedicated maximum-likelihood audit gives Delta chi2 =-24.6171and Delta AIC =-22.6171.The CMB+BAO best-fit difference is1.1960,while the SN contribution changes by-25.8131. The record includes final production chains, configurations, covariancematrices, logs, the exact FCLET likelihood source, optimizer inputs/outputs,canonical audit, claim register, scientific-environment snapshot, licensing,and SHA-256 manifests. Failed, stopped, partial, HOLD, smoke, and supersededchains are excluded. No reproducible Bayesian-evidence preference, universal all-datasetresolution, or parameter-free claim is made.
