You only need do disclose what could ever potentially be identified as AI. Otherwise it’s unenforceable. Even saying it’s used for code is debatable. You can’t tell once it’s compiled and can’t tell the difference between one developer breaking the companies policy or a policy that short snippets or auto complete are fine

Why would you disclose one line of AI code. It’s unidentifiable and meaningless. Like saying you don’t want code where auto complete was used and every character must be written by a human finger.

Kind of like using AI to place one single pixel in an image.
