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

we utilize JWST and ALMA observations to present direct evidence of RPS in the post-starburst galaxy A2744-JF-z3, residing in a galaxy group at redshift 3.06, the earliest such detection to date.

C2weakest assumption

The spectroscopic diagnostics and spectral energy distribution modeling correctly attribute the observed gas and dust removal specifically to ram-pressure stripping rather than other mechanisms such as AGN feedback, mergers, or observational biases at high redshift.

C3one line summary

Earliest direct evidence of ram-pressure stripping quenching star formation in a galaxy at z=3.06.
