Perhaps the only way to really to provide evidence against cheating accusations is to also provide a version history of the document the student worked on over time, plus notes (hand written preferably), and so on?

That would exponentially increase the workload of educators though, so it's unlikely to be taken up.

(I'm an instructor in a vocational field - students need to demonstrate their skills to achieve qualification, rather than write essays/reports/etc. - so AI isn't as a significant deal as it is in the academic fields.)
