I wonder, with what you said about how consciousness is "an irreducible quality not present in or derivable from matter (i.e., dynamics of subatomic particles)," what you'd say about Roger Penrose's "orchestrated objective reduction" thesis, which posits consciousness as an effect of quantum gravity (The Emperor's New Mind). Seems like that could be a derivation of matter, unless the answer is as simple as "quantum mechanics is wibbly wobbly timey wimey stuff and not conducive to proper materialism."
Kastrup engages with Penrose in the book(s). Yeah, "matter" as a term is 100% a moving goalpost. Kastrup has pointed out that right now we have a shift taking place in the relevant scientific fields towards what is really Idealism of some kind, but it'll still be called "physicalism" or "materialism" for some years.

Here's Kastrup and Penrose:

Note how Penrose says consciousness can't be computed. Not materialism in any classical sense.
