No, no, no, and (most likely) no, no, and no. You keep inventing these examples to make it sound as though there must be an infinite variety of things that all have to be judged individually. There aren't. I have very clearly defined a clean, simple definition of fudging. Does it cover all possible forms of DM overreach or inappropriate DM behavior? Heck no, no definition could ever do that. But it is very clear about what it is: changing the statistics or random number generators applied to, or caused by, a creature that has already entered play. The only possible grey area is "what if it's on the board but has not acted or been acted upon?" And frankly at this point I'm even willing to say "okay, fine, whatever, if it has literally not done anything at all yet, nor had anything at all done to it yet, then sure, maybe some minor tweaks--a couple points of AC, shifting its HP within its rolled options--is not the absolute worst thing ever.
