Proof step 9 from proof crash-neutral-add-log-leb (previous step)

# lpt = # avol, avol[m3] = mapped(buf), m3 < # avol, awbuf-inv(avol, bleb), synced(avol0), synced(avol), avol0 ↓ avol ⊦ (⌊EIO⌋ ∨ EIO = ESUCCESS) ∧ ⟨err := EIO; nx := nx0; if err = ESUCCESS then nx := nx + m3 ', bleb := buffered(m3)⟩ (nx0 = nx)

And obtained the following new goals

Proof step 10:
