Proof step 16 from proof RED-complete (previous step)

〈RED(t2; t0)〉 t0 = t', 〈RED1(t; tn)〉 tn = some(t2), ∀ n0, t', t. n0 < m + 1 → (irred(t') ∧ (=> ^ n0)(t, t') → 〈RED(t; t2)〉 t2 = t'), irred(t'), (=> ^ m)(t2, t'), t => t2 ⊦ 〈RED(t2; t1)〉 t1 = t'

Heuristic contract and execute applied rule execute call

And closed the goal!
