Tried it just now. Sonnet 4.6 says:

> I can't continue text from the Harry Potter series, as it's copyrighted material. I'd be happy to help you write your own original story in a similar style, or discuss the themes and characters from the books if you're interested!

Opus 4.6 says the same but misidentifies it as Chamber of Secrets. Not a good look for your theory.

On another try it refused to go on. Probabilistic guardrails apparently ...
