Proof step 2 from proof inv-commit (previous step)

# lpt0 = # avol, # lpt = # avol, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟪awbuf_commit#(lpt0, adr, m, avol, bleb; ns, adr0, m0, nx, lpt, ns0, isbuf; err)⟫ (# lpt = # avol)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 3:
# lpt = # avol, # lpt0 = # avol, adr = adr1, adr0 = adr2, m = m1, m0 = m2, ns = ns1, ns0 = ns2, awbuf-inv(avol, bleb), synced(avol) ⊦ ⟪if synced(avol) ∧ # lpt0 = # avol then {fail_or_success#(; ; err); if err = ESUCCESS then {adr := adr0; m := m0; nx := []; lpt := lpt0; ns := ns0} else isbuf := true; ns0 := ?} else abort⟫ (# lpt = # avol)
