While updating the slides to talk about magicians' card tricks and the use of
force decks, which contain pre-chosen cards that force the subject to pick one
of the magician's choosing (typically encountered as Svengali decks where you
can display all different cards but have the subject pick from all-identical
cards), the question answered itself: sleight-of-hand numbers.  So:

Quantum cryptanalysis has never factored a single non-sleight-of-hand number.
