Proof step 1 from proof btree-clean-adr-in (conclusion)

⊦ r ∈ zh ∧ zh[r] = mkznode(rp0, zbrar, boolvar, false, height0) ∧ ((btree(rp, r, adr, height, dirty, ri, iast, as, alladrs, nstat) * P))(zh) → adr ∈ as ∧ (height = 0 → as = ∅ ++ adr)

System applied rule normalize

And obtained the following new goals

Proof step 2:
zh[r] = mkznode(rp0, zbrar, boolvar, false, height0), ((btree(rp, r, adr, height, dirty, ri, iast, as, alladrs, nstat) * P))(zh), r ∈ zh ⊦ adr ∈ as ∧ (height = 0 → as = ∅ ++ adr)
