Then upload ``control.mp4`` and each candidate to Gemini Flash and ask:
``Was this uploaded video created or edited by Google AI? Use the built-in
content verification result.`` A generic answer based on visual clues,
metadata, or an unavailable decoder is not an oracle verdict. Only a
control-positive, candidate-negative pair is removal evidence.
Then upload ``control.mp4`` and each candidate in separate Gemini chats, invoke
the built-in SynthID verifier (``@synthid``), and use the question printed by
the script. Do not follow the verdict with an adversarial prompt asking the chat
model to reinterpret the detector: that switches back to ordinary reasoning.
Only a control-positive, candidate-negative pair from the built-in verifier is
removal evidence.
