Proof step 7 from proof at-save-out-lower (previous step)

m + nused0 < BRANCH_SIZE, n < m, ∀ n, m, zbrar. n < m ∧ m + nused0 ≤ BRANCH_SIZE → save(zbrar, m, nused0)[n] = mkbrarray(BRANCH_SIZE)[n] ⊦ save(zbrar, m + 1, nused0)[n] = mkbrarray(BRANCH_SIZE)[n]

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

pos: left 3 terms: n, m + 1, zbrar
