After investigating Bug 2008112, there are two possible improvements:

  • In UNSAFE_FUZZER_MODE, the MAC verifier should always accept inputs. I don't think there is any benefit in us rejecting ~50% of inputs.
  • The nickname callback should always return a unique nickname, making sure that we don't exit early.
