The AI will not resist its values being changed in the particular way that is specified in to trigger a U transition. It will resist other changes of value.
That's true; it will resist changes to its "outer" utility function U. But it won't resist changes to its "inner" utility function v, which still leaves a lot of flexibility, even though that isn't its true utility function in the VNM sense. That restriction isn't strong enough to avoid the problem I pointed out above.
I will only allow v to change if that change will trigger the "U adaptation" (the adding and subtracting of constants). You have to specify what processes count as U adaptations (certain types of conversations with certain people, eg) and what doesn't.
Oh, I see. So the AI simply losing the memory that v was stored in and replacing it with random noise shoudn't count as something it will be indifferent about? How would you formalize this such that arbitrary changes to v don't trigger the indifference?
By specifying what counts as an allowed change in U, and making the agent in to a U maximiser. Then, just as standard maximises defend their utilities, it should defend U(un clubbing the update, and only that update)
