OK, it means logical consistency relative to some initial axioms (which you take to be Peano's for the integers). But I take it that there are many continuations which branch. Is a continuation a consistent continuation up to the last branching vertex before 0=1 is proven - or do only infinite continuations count as consistent? I also wonder about basing this on Peano's axioms. Would it matter if we took arithmetic mod some very large integer instead, i.e. finite arithmetic as done is real compters? Wouldn't this ruin some of your diagonalizations?
