Yet ""COMP is true" AND "COMP is false"" is necessarily false.

How? Just because you bet on something doesn't make it a correct bet. Just
because you hold two contradictory propositions to have equal credence,
doesn't make them both correct. I don't see where this is coming from.

The UDA only shows that they cannot be ontologically primitive, or

Consider an (unrealistically long) dream wherein the dreamer observes
several violations of the real-life laws of physics (wrong proton mass,
broken glasses reassembling themselves, whatever.). He then reasonably
concludes that he is dreaming. In other words he reduces his experience in
the dream to a "more fundamental" physical reality wherein he is asleep,
his brain is in state X, and so on. He is therefore denying the
primitiveness of his dream -- it is, in your terminology, an illusion.

It seems to me that by your reasoning, the idea that the dreamer is
dreaming undermines the result itself, so that no one can ever legitimately
say "I am dreaming". If I see a cup of coffee getting hotter on a cold day,
or have conversations with long-dead relatives, I cannot say that I am
dreaming, because if I am dreaming then there is no reason to take my
reasoning seriously. (A lot of lucid dreamers would beg to differ!)

Is this a misrepresentation of your view? It is a somewhat subtle issue.

How do you know this?

I agree, this would be very helpful. I wouldn't mind if it got a little
technical, either.
