GRPO's AV Intelligence is sketchy; it's the thing that leads to steganography, it's the
thing that lets it confabulate what the LLM is thinking from shallow patterns,
instead of deeply checking.
To translate from activation-neuralese to English, one must mostly learn many vocabulary pairs (akin to natural languages); it's memorization.
Probably a $100 GPU-coins or greater insight than me is enough to know for sure.
