Posterior sample chains from the generational pipeline: gen359 holds the headline CPL and wCDM chains (4 chains each, up to 144k samples) over DESI DR2 BAO + Pantheon+ + CMB; gen114/115 are earlier and full-covariance variants. NumPy .npz arrays.

Serving, honestly
Downloads are served directly from this server today; an object-storage mirror (Tigris) is planned and flips on via config. The upstream archive is always the canonical copy — cite it, not us. Anything we serve must match its published hash.
