1. Multiplicative Commutativity Is Additional to Complete Ring Qualification

Use the same qualified complete finite unital ring on Fin(8)={0,…,7}, with addition=[[0, 1, 2, 3, 4, 5, 6, 7], [1, 0, 3, 2, 5, 4, 7, 6], [2, 3, 0, 1, 6, 7, 4, 5], [3, 2, 1, 0, 7, 6, 5, 4], [4, 5, 6, 7, 0, 1, 2, 3], [5, 4, 7, 6, 1, 0, 3, 2], [6, 7, 4, 5, 2, 3, 0, 1], [7, 6, 5, 4, 3, 2, 1, 0]] and multiplication=[[0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 0, 1, 0, 1, 0, 1], [0, 2, 0, 2, 0, 2, 0, 2], [0, 3, 0, 3, 0, 3, 0, 3], [0, 0, 2, 2, 4, 4, 6, 6], [0, 1, 2, 3, 4, 5, 6, 7], [0, 2, 2, 0, 4, 6, 6, 4], [0, 3, 2, 1, 4, 7, 6, 5]] in label order. All unital-ring axioms, including distinct two-sided identities, must already hold. The identity labels need not be 0 and 1. Commutativity is a separate multiplication obligation; even a commutative ring may have nonzero zero divisors and need not be a field. Give (n,zero,one,all [a,b,ab,ba] failures with a<b in label order,commutative?,classification). Classification is commutative_ring or unital_ring_not_commutative.

Compare both multiplication orders for every distinct unordered pair. Off-diagonal failures disprove commutativity; the full ring qualification is a prior premise rather than something repaired by this audit. An exact finite or named-formula slice does not automatically establish an arbitrary infinite theorem. The exact result, retaining the requested order, is (8, 0, 5, [[1, 2, 0, 2], [1, 3, 1, 3], [1, 6, 0, 2], [1, 7, 1, 3], [2, 3, 2, 0], [2, 4, 0, 2], [2, 6, 0, 2], [3, 4, 0, 2], [3, 7, 3, 1], [4, 6, 6, 4], [4, 7, 6, 4], [6, 7, 4, 6]], No, unital_ring_not_commutative).

(8, 0, 1, [], Yes, commutative_ring)

Compare both multiplication orders for every distinct unordered pair. Off-diagonal failures disprove commutativity; the full ring qualification is a prior premise rather than something repaired by this audit. An exact finite or named-formula slice does not automatically establish an arbitrary infinite theorem. The exact result, retaining the requested order, is (8, 0, 1, [], Yes, commutative_ring).

(0, 6, 1, 0, 0, 0, Yes)

Start each power at the actual multiplicative identity. At exponent zero all powers are the identity. This identity is used under the full commutative-ring premise, not to certify commutativity from one instance. An exact finite or named-formula slice does not automatically establish an arbitrary infinite theorem. The exact result, retaining the requested order, is (0, 6, 1, 0, 0, 0, Yes).

(1, 2, 3, 1, 1, 2, 6, 1, Yes)

Use the addition and multiplication tables throughout. The two copies of ab are added in the ring; do not substitute a carrier label called 2 for repeated addition. Zero divisors do not invalidate this identity. An exact finite or named-formula slice does not automatically establish an arbitrary infinite theorem. The exact result, retaining the requested order, is (1, 2, 3, 1, 1, 2, 6, 1, Yes).
