So one that is almost certain to happen given some time?

"Understanding all occurences of it" seems like a good criterion for allowing potentially mass murderous work or not. That said, it sounds stricter than what it is. We just need them to know how a thing works and not be doing "sorcerer's apprentices" style peek and poke work.
They don't need to "prove a negative". For example we don't asks scientists to prove that "water can't explode and destroy the earth" to let them work with it casually. It's enough that they know it well. Do they know prion as well as they do water?
