The board wants their cake and eat it too.

They want AI to write all code but also still be able to fire humans for failure, because an AI can't be blamed right now.

Boy I can't wait for this employment norm. Fired because you weren't allowed to take the time to review important code but "You are responsible"

I wish Executives were required to be that "responsible"

Just reject a bunch of PRs two days before code freeze. They can go next sprint. In fact ask AI to provide a plausible reason for rejection. If anyone overrides, you are covered.
