Not in tech, so does the authority granting license to proceed do code reviews?

Because when I submit building plans, they are manually reviewed and approved (or denied) by registered architects, engineers, and planners employed by the authority for just this purpose.

Gaming Commissions oversee gambling machines and will audit code to ensure the RNGs are accurate, return to player meets the expected requirements, and so forth.

I'm sure other highly regulated industries also have their code audited.
