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 comparison reveals that lens model predictions, even the most precise ones, consistently overestimate the magnification, with a offset of Δμ > 1 mag.

C2weakest assumption

The photometric derivation of magnifications from the lensed SN H0pe is accurate and free of systematics that would invalidate the direct comparison to lens-model predictions (abstract, paragraph on purely observational comparison).

C3one line summary

Lens models for PLCK G165.7+67.0 overestimate the magnification of lensed SN H0pe by Δμ > 1 mag, while photometric estimates align with ΛCDM.
