It seems to me that we would not observe any sign of a collapse in a

Correct. But the CI says you can't learn the result of a measurement without the wave
function collapsing. Actually it was never entirely defined when the collapse happened,

For DD's experiment to work, there must be two definite results which are definitely

measuring a definite result.
I'm not clear on what you mean by two definite results. In order to detect an
interference pattern you need to send many particles through Young's slits. So I assume
the two results must be an ensemble for which there was no which-way observation by the
conscious AI and another ensemble for which the observation was made for each particle,
but then quantum-erased.
