Dear Mirai and Federico and Friends,

    Could we cover the "White Rabbit" and "Harry Potter" universes by
considering that for a pair of systems to interact their individual
histories must not contradict each other? This, I think, would also cover
interactions between the MWI "branches".

Kindest regards,
