alt Hacker NewsClean-room reverse engineering involves two teams: one with access to the thing being reverse engineered, who write documentation of it, and the one in the clean room who do the implementation based only on the documentation. There's no reason you could not use AI for the first part, as the documentation is then evidence that you are only looking at behaviour and not source code.
Using it inside the clean room is more of an issue.
If you use have the first team use one provider to write the spec and a completely different provider for the implementation team, I would expect you would be covered, but it probably will take the first players in this game to establish that precedent by having their cases tried in court.
