The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In the flat ΛCDM cosmological model, DESI (FS+BAO), combined with a baryon density prior from Big Bang Nucleosynthesis and a weak prior on the scalar spectral index, determines matter density to Ω_m=0.2962±0.0095, and the amplitude of mass fluctuations to σ_8=0.842±0.034.

C2weakest assumption

The full-shape modeling pipeline, including redshift-space distortion modeling and systematic corrections, has been validated in supporting papers; any unaccounted modeling bias or incomplete marginalization over nuisance parameters would directly affect the reported parameter values and error bars.

C3one line summary

DESI DR1 full-shape clustering yields Ω_m = 0.2962 ± 0.0095 and σ_8 = 0.842 ± 0.034 in flat ΛCDM, tightening to H_0 = 68.40 ± 0.27 km/s/Mpc with CMB and DESY3, while favoring w_0 > -1, w_a < 0 and limiting neutrino mass sum to < 0.071 eV.
