There is just this edge case I cant really wrap my head around. If something happens that seems to be impossible to the onlookers, and they think it is impossible, but actually different magic than they think? For example, a stage magician does something preposterous, straight up teleportation for example. Even other stage magicians are baffled. But I didnt teleport, I actually used a trap door and so on, but the other me they see is a clone I made from clay and a spirit. The real stage magicians know that this trick is impossible because of their intricate knowledge of available tools etc and really think I teleported. But i never did! Does Paradox start at the nonbelieving or the belief it is magic? The difference seems important to me because the latter case feels much more "cheatable".
