Proof step 6 from proof unmodified-load-adr-node (previous step)

iast[adr] = indexnode(save(zbrar, 0, nused + 1), bv1, nused + 1), n < BRANCH_SIZE, nused < BRANCH_SIZE, adr ∈ iast, n ≤ nused ⊦ load(save(zbrar[n])).adr = zbrar[n].adr

User applied rule structural induction

And closed the goal!

Rule argument

term: zbrar[n]
