Proof step 36 from proof synced-remap (previous step)

# lpt = # avol, m2 < # avol, awbuf-inv(avol, bleb), synced(avol), avol0 ↓ avol[m2, unmapped], ⌊err2⌋ ⊦ ⟨if err2 = ESUCCESS then avol[m2] := mapped(mkbuf(0)) else {skip or avol[m2] := unmapped}⟩ (synced(avol) ∧ avol0 ↓ avol), buffered(m2) = bleb, avol0[m2] ↓ avol[m2]

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 37:
# lpt = # avol, m2 < # avol, awbuf-inv(avol, bleb), synced(avol), avol0 ↓ avol[m2, unmapped], ⌊err2⌋ ⊦ ⟨skip or avol[m2] := unmapped⟩ (synced(avol) ∧ avol0 ↓ avol), buffered(m2) = bleb, avol0[m2] ↓ avol[m2]

Used simplifier rules: ⊦ ⌊err⌋ → err ≠ ESUCCESS; (s)
