an authoritative payoff matrix that X can't safely calculate xerself.

Why not? Can't the payoff matrix be "read off" from the "world program" (assuming X isn't just 'given' the payoff matrix as an argument.)

The one-player game that I wrote out is an example of a NDT agent trying to read off the payoff matrix from the world program, and failing. There are ways to ensure you read off the matrix correctly, but that's tantamount to what you do to implement CDT, so I'll explain it in Part II.
