Three capabilities were listed as un-probeable. Only one of the reasons held.

Voice cloning 'needs a reference sample' — and espeak produces one, with a
transcript we know exactly because we chose the sentence. Audio generation was
'minutes of GPU': asking for 2 seconds instead of the 10s default proves the
model renders audio for a fifth of the cost. Video was 'real money': the
smallest clip a model can make — 9 frames, 256x256, 4 steps — proves the path
without paying for a film. 'Expensive' was an argument for asking for less, not
for proving nothing.

Generated media has no ground truth, so these check that media came back at all;
a 200 carrying nothing is still a failure. Face swap stays reachability-only and
now says why: a drawn face does not survive face detection, and a real person's
photo is not ours to use.
