Maybe I'm arguing over a point of language, but it still seems to me that if
A supervenes on U, then it is entirely explained by U. If A surprises
despite full knowledge of U, then that just means your knowledge of U was
incomplete: that is, you have to add to your list of properties of the
components of U that lots of them interacting in a particular way result in
thermodynamic irreversibility, or intelligence, or whatever. It's just that
sometimes the result of the interaction is obvious, and other times not.

My apologies, you are right... weird when you have a *really clear* memory
of something and it turns out to be wrong.
