I can see how someone could interpret HPMoR thus far as being exactly that, with occasional sidequests. The catch being that Harry doesn't realize he's slowly letting Voldemort out of the box.

In-universe, though, the interdict of Merlin is an excellent reason to force him to interact with Voldy even if he knew what he was doing (assume perfect Oclumancy would be attained before he'd take any such risks). I mean, this has already been used once to get him to let an unfriendly intelligence out of a literal box (the Stanford Prison Experiment).

Well, and Harry's intelligence is supposed to be roughly equivalent to Eliezer's before he started working on the friendly part of FAI, and Eliezer 2013 doesn't seem confident that he could keep an AI in a box (or at least, that's the impression I've gotten). So MoR Harry would almost definitely fail.
