The proof shows that rogue waves most likely arise through \"dispersive focusing\", where phase synchronization produces constructive amplification of the water crest.\nThe main difficulty in justifying this mechanism is propagating statistical information over such long timescales, which we overcome by combining normal forms and probabilistic methods.
