CR-ΛCDM v2.7.1 — Computational pipeline (corrected release)

This record provides the corrected and working computational pipeline for the CR-ΛCDM model. It supersedes the original CR-ΛCDM v2.7 computational record, which contained an early version of the pipeline that was not fully functional in its published form. The v2.7.1 archive (crlcdm_v2p7p1_comput_zenodo.tar.gz) is reconstructed from the working OVH snapshot that was actually used to produce the first full-likelihood MCMC runs (released separately in CR-ΛCDM v2.8 — Full-likelihood MCMC data). The unpacked archive exposes a cleaned and portable layout: – configs/ : YAML configs for baseline ΛCDM sanity checks and CR-ΛCDM externalP / externalPk runs, derived from the OVH snapshot. – docs/ : documentation skeleton (environment, OVH usage, local usage, links to v2.8 and v3.1). – scripts/ : placeholders for orchestration and helper scripts. – class_patch/ : placeholder for CR-ΛCDM-specific modifications to CLASS (bounce / CPT-symmetric background, IR cutoff, etc.). Intended use – v2.7.1 (this record): reference computational pipeline. – v2.8: reference MCMC data release (chains, covmats, checksums). – CR-ΛCDM v3.1: reference scientific analysis and interpretation based on these chains.
