To beat an almost dead horse, this all goes back to the fact that the
proposed protocol does not define an unambiguous algorithm to check if a
valid contract exists or not.  Without a precise definition of a valid
contract and a method to check it, the protocol is incomplete and attempts
to analyze it have to make a lot of guesses and assumptions.
