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

the SN 1987A neutrino data can remarkably yield values for the three neutrino masses, and not merely upper limits

C2weakest assumption

the spread in neutrino emission times from SN 1987A data is too great for the method to work (and the related assumption that the one-phase emission model is valid and that Mont Blanc data belongs to the event)

C3one line summary

SN 1987A neutrino timing data yields explicit values for the three neutrino masses under a single-phase emission model after rejecting three standard assumptions about unrelated signals, mass limits, and emission spread.
