can assume a baseline level of “ most {information, using this word here to mean like the corpus of human knowledge or something} was frely available and shared prewar and anybody with the resourcs and desire to has some sort of databse of scientifc knowledge etc in their bunker system”
maybe stuff regarding mutation specifically was more closel guarded. this means corpus and governments have pretty sick mutans and a significant advantage
still fits in with the idea of startups doing jank as mutations, also leaves rom for conflict if one corporation sees mutants from another withmutations only they know how to do or something like that
