Universality over all partial recursive functions is not a finite enumeration. The computation uses a finite universe that can actually be saturated: all 16 boolean functions of two bits. The radius-4 rule and the Turing machine are different constructions aimed at that ceiling; the elementary rules, including rule 0, are the progressive family underneath.
