Proof step 1 from proof unmodified-clean-leaf-subseteq (conclusion)

⊦ iast0 ⊆ iast1 ∧ unmodified(adr, mkznode(rp0, zbrar0, bv0, false, nused0), iast0) ∧ unmodified(adr, mkznode(rp1, zbrar1, bv1, false, nused1), iast1) → (bv0 ↔ bv1) ∧ nused0 = nused1

System applied rule normalize

And obtained the following new goals

Proof step 2:
unmodified(adr, mkznode(rp0, zbrar0, bv0, false, nused0), iast0), unmodified(adr, mkznode(rp1, zbrar1, bv1, false, nused1), iast1), iast0 ⊆ iast1 ⊦ (bv0 ↔ bv1) ∧ nused0 = nused1
