My gut feeling is no, a work is not a derivative of a compliance test suite that it passes and was used to guide it. But I'm not a lawyer.

We’re going to be in a very weird place:

* LLMs make it trivial to recreate almost any software using its test suite (maybe not a derivative work)

* LLM generated code has no copyright (according to current court interpretations)

Soon we will be able to make an unlicensed copy of anything if we have its test suite and a little money for tokens.
