Proof step 41 from proof unmodified-payload (previous step)

BRANCH_SIZE = # zbrar, iast[adr] = indexnode(brar, bv1, nused), zbrar[n] = mkzentry(key, adr0), indexnode(brar, bv1, nused) = save(mkznode(rp, zbrar, bv1, false, nused)), n < BRANCH_SIZE, n < nused, sorted(zbrar, 0, nused), adr ∈ iast, nused ≤ BRANCH_SIZE ⊦ ∃ n0. n0 < nused ∧ load(brar[n0]).entry? ∧ load(brar[n0]).key = key

User applied rule exists right

And obtained the following new goals

Proof step 42:
BRANCH_SIZE = # zbrar, zbrar[n] = mkzentry(key, adr0), iast[adr] = indexnode(brar, bv1, nused), indexnode(brar, bv1, nused) = save(mkznode(rp, zbrar, bv1, false, nused)), n < nused, n < BRANCH_SIZE, sorted(zbrar, 0, nused), adr ∈ iast, nused ≤ BRANCH_SIZE ⊦ n < nused ∧ load(brar[n]).entry? ∧ load(brar[n]).key = key
