the whole thing about the coming empire. sovereign would be around, monitoring the galaxy from time to time, and see an intergalactic empire with a 50k year mission to prepare for the next invasion. and javik’s people would have known about this, because vigil knew what sovereign does between invasions and told us so.

unintentional plot f up? vigil learned about sovereign’s monitoring after the extinction? javik and co just didn’t know what vigil/ilos knew, and would have found out the hard way a few hundred or thousand years into their plan? something else?
