Thank you for writing this up. Looks good to me.

I do not have a strong opinion regarding if we should encipher the token (using a fixed key) to enforce the client to consult the integrity tag. It's good in terms of enforcing verification. It does not change the complexity of the design. There would be a performance penalty when using a software cipher (i.e. when you do *not* have AESNI).
