Countermodel certificate for an equational-theories implication, closed by decide. A magma on Fin 7 with an inline List operation table satisfies x ◇ y = z ◇ (w ◇ u) but not x = x ◇ x. Checking the certificate evaluates the decidable instance over all 7^5 ≈ 17k five-tuples; every unfolds to a linear lookup into the list.

From a corpus of certificates generated for the SAIR math distillation challenge (equational theories track). The small end of the list-table family; magma-list-pair-n21 is the same workload at a larger scale.
