An independent DESI DR2 analysis finds only modest, non-robust significance for evolving dark energy with late-time datasets alone, qualifying the approximately 3-sigma fit-level preference reported in another combination. DIRECT_TEXT

We find that each dark energy model predicts values in the w0 > -1, wa < 0 quadrant... Consistently, the statistical significance remains modest, with Nσ ∼ 1.1–2.3, and no model showing a robust preference for dynamical dark energy using late-time datasets alone.
