I know Scott wouldn't go as far as me. For me, all such irreversible

agreeing that Geiger counters are unlikely to be conscious, I would

That sounds remarkably like the "many minds" interpretation of
quantum mechanics. This is disfavoured by most scientists because it
leaves the physics of the billions of years before the emergence of
the first "conscious" creature unresolved -- the first consciousness
would cause an almighty collapse on the many minds reading.
Each consciousness causes "an almighty collapse" in er own mind
independently of any other. It's a pure 1p phenomena.
It is actually a 3p phenomenon because there is inter-subjective
agreement about the fact that measurements give definite results.
There is no collapse at all at the 3p level, nor even decoherence as such.
Decoherence is a well-understood physical phenomenon that has been
widely observed. I do not know what you mean by saying "nor even
decoherence as such." Also, you seem to be confusing the
inter-subjective 3p view with Tegmark's bird view. There is no person,
body, or consciousness that ever has the bird view -- the bird is a
purely formal construct and has nothing to do with mind or
consciousness. Even though everything might remain unitary at that
level, no one can ever experience the consequences of that unitary
evolution.
