 (The set of valid guesses in C is just a lot more restricted since they do not have `wrapping_offset`, and the model does not cover `restrict`.
 That means they can actually feasibly give an algorithm for how to do the guessing.
 They don't have to invoke scary terms like "angelic non-determinism", but the end result is the same -- and to me, the fact that it is equivalent to angelic non-determinism is what justifies this as a reasonable semantics.

-Presenting this as a concrete algorithm to pick a suitable provenance is then just a stylistic choice.

+Kudos go to Michael Sammler for opening my eyes to this interpretation of "user disambiguation", and arguing that angelic non-determinism might not be such a crazy idea after all.

 
 What is left is the question of how to handle pointer-integer transmutation, and this is where the roads are forking.
 PNVI-ae-udi explicitly says loading from a union field at integer type exposes the provenance of the pointer being loaded, if any.
