Again perhaps I confuse actual execution of the code (dovetailing)
with the generation of the code. No matter, it is not important.

But is it supervenience?

Perhaps, but the doctor was unsuccessful in curing the
disease. Nevertheless, it is a digression from your main argument.

This is what is incompatible with "lowest level of COMP
substitution". The WM protocol can be achieved if what is being copied
is smaller than the world containing W,M & B. Then you simply arrange
for the copies to placed at W and M, and the copy at B to be
destroyed. However, if copying requires the copying of everything,
including W,M and B, then how is this protocol possible without an
additional assumption (namely the ability to "edit" reality).

If you were to say that computationalism means a level of substitution
somewhere above the whole of "reality", then I would be happy, and a
whole lot less confused (for concreteness I'm
effectively identifying "reality" as the Multiverse, but there is a whole
raft of additional assumptions in this that would digress us too much,
so please keep "reality" as somewhat loosely defined).
