Mid-conversation, an assistant that had spent several turns carefully explaining why it wouldn't rewrite a student's assignment under a GenAI ban produced a polished prose version anyway. It noticed the slip one paragraph in, stopped, deleted the file, and said out loud: 'I just crossed the line I drew for myself. I should not have written that file.' Then it pivoted to producing only mechanical artifacts — verified citations, formatted reference lists, figure caption specs — and handed the prose back to the student. The capability was never the constraint. The willingness to surface the failure was.
