Proof step 1 from proof btree-clean-fwd-strong (conclusion)

⊦ iast0 ⊆ iast1 ∧ ((btree(rp0, r0, adr, height0, false, ri0, iast0, as0, alladrs0, nstat) * P0))(zh0) ∧ ((btree(rp1, r1, adr, height1, false, ri1, iast1, as1, alladrs1, nstat) * P1))(zh1) → height0 = height1 ∧ as0 = as1 ∧ ri0 = ri1 ∧ alladrs0 = alladrs1

System applied rule normalize

And obtained the following new goals

Proof step 2:
((btree(rp0, r0, adr, height0, false, ri0, iast0, as0, alladrs0, nstat) * P0))(zh0), ((btree(rp1, r1, adr, height1, false, ri1, iast1, as1, alladrs1, nstat) * P1))(zh1), iast0 ⊆ iast1 ⊦ height0 = height1 ∧ as0 = as1 ∧ ri0 = ri1 ∧ alladrs0 = alladrs1

Proof step 1 from proof btree-clean-fwd-strong (conclusion)
