- fn* form inside extend-type/extend-protocol must be @[...] (array) so eval-list dispatches fn* special form (tuples hit tuple? → map eval-form) - call forms stay @[...] (array) for correct special form dispatch via eval-list - All 4 protocol tests pass: defprotocol, extend-type, extend-protocol, satisfies? - 315 ok, 2 fail (pre-existing, unchanged)
