Code and Outputs for Tension of Space as Dark Energy

File scan_flux_fit: This script performs the pointwise benchmark fit of the flux-tube running-tension model to the effective CPL target used in the manuscript. It evaluates the model equation of state over the interval 0 ≤ z ≤ 1.6, projects the resulting curve onto the CPL form (w0,wa), and scans a restricted parameter grid in (a_i, η_i, Γ, κ) for fixed n. The script reports the best coarse-grid point for each of n=2,3,4 and also performs a local refinement around the best restricted case n=2. Its outputs are the summary files flux_fit_summary_restricted_n.csv and flux_fit_refined_n2.csv, which were used to quote the benchmark scan results in the manuscript. File w_0_w_a_python: This script constructs the compressed (w0,wa) target used in the manuscript from publicly available DESI DR1 value-added cosmology chains. It downloads the relevant Cobaya chain files for the DESI DR1 BAO + Pantheon+ + Planck 2018 dataset combination, identifies the w0,wa and weight columns, and computes the weighted posterior mean vector and covariance matrix. It then writes these quantities to a small LaTeX macro file, w0wa.tex, for direct inclusion in the manuscript. The script does not run Cobaya itself; it only post-processes the published posterior chains.
