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

A 3+1 scenario in which sterile neutrinos feel a novel matter potential Vs proportional to background density of ordinary or (asymmetric) dark matter is able to explain several anomalies.

C2weakest assumption

The existence and specific negative value of the new sterile matter potential Vs (f ≈ -20) that is introduced by hand to fit the data rather than derived from a deeper theory.

C3one line summary

A sterile neutrino with a novel density-dependent matter potential Vs resolves multiple oscillation anomalies when Vs is negative and mixing angles are small.
