Proof step 4 from proof inv-unmap (previous step)

# lpt = # avol, m = m1, m0 = m2, m2 < # avol, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟪if synced(avol) ∧ m0 < # avol ∧ buffered(m0) ≠ bleb then avol[m0] := unmapped else abort⟫ (awbuf-inv(avol, bleb) ∧ # lpt = # avol), buffered(m2) = bleb

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals
