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

Parametrizing the z-dependence as a0(z)= a0(0) + a1 * z, we obtain a1 = 1.59+/-0.1 *10^-10 m/s^2, providing evidence for a z-evolution.

C2weakest assumption

The 3D forward modeling with disk-halo decomposition and pressure-support corrections accurately recovers the intrinsic accelerations without significant systematic bias from the choice of dark-matter halo profile or sample selection.

C3one line summary

The radial acceleration relation persists at intermediate redshifts but with a characteristic acceleration scale that increases linearly with redshift.
