It might not be copied from its training set (yet), but it is copied from its context window.
The code it produces is a clear copy of the spec or the existing code that is fed to it as part of the task. It is just following the spec instructions, and some models follow it so closely that they get caught out by the lies/adversarial traps in the spec. Opus 5 is better at seeing through the lies, but it still very much copies from its context window.
