Proof step 14 from proof unmodified-clean-fwd-zbrar2 (previous step)

# zbrar0 = BRANCH_SIZE, BRANCH_SIZE = # zbrar1, zbrar0[n] = mkzentry(key, adr0), iast[adr] = indexnode(save(zbrar0, 0, nused), bv, nused), mkzbranch(key', adr1, rp) = zbrar1[n], n < nused, n < BRANCH_SIZE, adr ∈ iast, nused ≤ BRANCH_SIZE, ∀ n0. n0 < BRANCH_SIZE → save(zbrar0, 0, nused)[n0] = save(zbrar1, 0, nused)[n0] ⊦
