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

Our analysis confirms that the evidence for dynamical dark energy, particularly at low redshift (z ≲ 0.3), is robust and stable under different modeling choices.

C2weakest assumption

The assumption that systematic uncertainties in DESI BAO measurements, Planck data, and supernova compilations do not introduce spurious signals mimicking dynamical dark energy evolution.

C3one line summary

Extended analysis of DESI DR2 data confirms robust evidence for dynamical dark energy with phantom crossing preference, stable under parametric and non-parametric modeling.
