I have a strong example for simulationism, but I guess that might not be what you’re looking for. Honestly I’m not sure I know any really important multiversal trade protocols. I think their usefulness is bounded by the generalizability of computation, or the fact that humans don’t seem to want any weird computational properties..? Which isn’t to say that we wont end up doing any of them, just that it’ll be a thing for superintelligences to think about.
In general I’m not sure this require avoiding making your AI CDT to begin with, I think it’ll usually correct its decision theory later on? The transparent newcomb/parfit’s hitchhiker moment where it knows that it’s no longer being examined by a potential trading partner’s simulation/reasoning and can start to cheat never comes. There’s no way for a participant to like, wait for the cloons in the other universe to comply, and then defect, you never see them comply, you’re in different universes, there’s no time-relation between your actions! You know they only comply if (they will figure out) that it is your nature to comply in kind.

I do have one multiversal trade protocol that’s fun to think about though.
