Proof step 2 from proof synced-unmap (previous step)

⟨awbuf_unmap#(m, adr, m0, nx, lpt, ns, bleb, isbuf; avol)⟩ (adr0 = adr ∧ m1 = m0 ∧ nx0 = nx ∧ lpt0 = lpt ∧ avol0 ↓ avol ∧ ns0 = ns), # lpt = # avol, m < # avol, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟨awbuf_unmap#(m, adr, m0, nx, lpt, ns, bleb, isbuf; avol)⟩ (synced(avol) ∧ adr0 = adr ∧ m1 = m0 ∧ nx0 = nx ∧ lpt0 = lpt ∧ avol0 ↓ avol ∧ ns0 = ns), buffered(m) = bleb, adr0 = adr ∧ m1 = m0 ∧ nx0 = nx ∧ lpt0 = lpt ∧ avol0 ↓ avol ∧ ns0 = ns

Heuristic contract and execute applied rule execute call

And obtained the following new goals

Proof step 3:
