Matter has been a succesful explanation for many centuries -- an
aposteriori explanation. Who said that only apriori explanations are
acceptable ?
Is that the premiss underlying your other premisses ?

Matter can explain anything computationalism or
mathematics can explain, since any computaiotnal
or mathematical structurecan be implmented in matter.

It can also provide support for time and qulia, and
explain away HP universes.

Only if the "usual sense of realist mathematicians" is
a sense amouting to the kind of existence I actually
have (even if I mistakenly think that is material existence,
I still have ot exist in some sense in order to make the mistake!).

But that is what I have been saying all along. The argumentative
work is being done by the hidden assumption of Platonism,
not the explicit assumption of computationalism.

Everett is compatible with standard computationalism.
It doesn't have to assume computationalism. Any non-magical
theory of mind will do.

Not just computationalism, because you need to
assume a UD exists

a) " just in the usual sense of realist  mathematicians"
[ a "realist mathematician" being a Platonist .. ]

b) in some way real enough for me to be part of  its output.

Computationalsim is a thesis about minds, not about maths...
