A single high-energy neutrino event implies that UHE proton sources must evolve strongly like high-luminosity AGN, but this is disfavored when including null results from other detectors, with proton fraction constrained to about 20% at 20 EeV by composition data.

Implications of a Cosmogenic Origin of KM3-230213A for Ultra-High-Energy Protons
