It found a cheaper way to run itself

Same answers. A third of the Jev requests.

We let the AI redesign how Greenlight runs its Jev checks: only re-check what a new document affects, and ask related questions together. A fixed test it couldn't edit decided whether to switch: no condition wrongly marked as met, no drop in accuracy, and fewer requests. It passed.
