Four BAO-based estimators of the sound-horizon ratio r_d/r_d^fid, each built on a different subset of assumptions (distance duality, flatness, standard ruler), all agree on a single redshift-independent value with current DESI DR2 + Pantheon+ + CC data.

The cosmic tetrarchy: four estimators breaking the assumption degeneracy in cosmological distance tensions
Four BAO-based estimators of the sound-horizon ratio r_d/r_d^fid, each built on a different subset of assumptions (distance duality, flatness, standard ruler), all agree on a single redshift-independent value with current DESI DR2 + Pantheon+ + CC data.
