You make a good point about discarding the source of random noise that the one-time pad is being applied to, and just focusing on the thing that's generating that one-time pad.

But I still don't know where to draw the line and how to justify it.

If that source of random noise mapped to a Turing machine running consciousness.exe for a short period of time by sheer chance without a one-time pad being applied to it by an external observer, would that classify? If we observed that this mapping held true by sheer chance as we observed additional bits in this random noise source, what about then? Does it make a difference that it's a random noise source that happens to be corresponding to a Turing machine for a period of time, and not an "actual" computer? And if that matters, what about the point that actual computers aren't perfectly deterministic, either?
