So it is baked in to the rules; but is it a "fudge"?
When I was giving my answer, I assumed that the question is not about using existing mechanics (rerolling with Luck, spending Fate Points, declaring Success at a Cost, and other mechanics that can turn a failure into a success), but rather rolling a die with the expectation that certain results have certain meanings yet then either substituting an arbitrary alternative number for the result or not following up with the consequences of the resulting number (often secretly).
That was also my assumption.
Like you roll a crit on your attack but you say "oh, that's a miss." or the other way around.
