Right. Actually, forget about both of those; all that matters is whether it actually does modify the simulation's contents or copy out data that includes a mind at least once. And, come to think of it, the intervention would also have to be inside our past or future light cone, which might lower the fraction pretty substantially (it means any outer universe which instantiates our entire infinite universe, but makes only finitely many interventions, doesn't count).

Although - there are some interpretations of consciousness under which, upon death, the fraction of enclosing universes which copy out minds doesn't matter, only the proportions of them with different qualities. In that case, the universe would act as though there were no gods or outer universes until you died or performed enough iterations of quantum suicide, after which you'd end up in a different universe. I'm not sure how much credence I give to those interpretations.
