Proof step 19 from proof synced-add-log-leb (previous step)

# lpt = # avol, nx + m3 ' = nx1, avol[m3] = mapped(buf), err0 = ESUCCESS, m3 < # avol, awbuf-inv(avol, bleb), synced(avol), avol0 ↓ avol, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ∃ err0. (⌊err0⌋ ∨ err0 = ESUCCESS) ∧ ⟨err := err0; if err = ESUCCESS then nx := nx + m3 ', bleb := buffered(m3)⟩ (nx1 = nx)
