I kinda want to invoke Hanlon's razor here... on the model. We shouldn't assume it's subversive when it might just be incompetent. Any difference between tests and real world production could lead to different outcomes just by chance, one working randomly better than the other for no particular reason.

I did not mean to imply it's being subversive. My theory is it's some byproduct mechanism of attention, where you're now basically telling it "your goal is to pass this set of tests" rather than "implement this piece of code" when "implement this piece of code" may involve it forgetting about a rule due to convenience, context exhaustion, whatever.
