Re: the third point, I think it’s important to differentiate between f(k(f)) and t(k(f)), where t is the true prediction, that is what actually happens when an agent performs the action A.
f(k(f)) is simply the outcome the agent is aiming at, while t(k(f)) is the outcome the agent eventually gets. So maybe it’s more interesting a measure of similarity in B, from which you can compare the two.
