It seems pretty extensive (1696 cases identified so far), and appears to be updated regularly. :)

And AI layers are so good that even OpenAI complained that it would be unable to navigate compliance if every US state can have it's own AI legislation.
And they have infinite access to AI that passed the bar exam and is brandished with "PhD-level intelligence."
