Proof step 2 from proof crash-neutral-remap (previous step)

# lpt = # avol, adr = adr0, lpt0 = lpt, m0 = m1, ns = ns0, nx = nx0, m < # avol, awbuf-inv(avol, bleb), synced(avol0), synced(avol), avol0 ↓ avol ⊦ ⟨awbuf_remap#(m, adr0, m1, nx0, lpt, ns0, bleb, isbuf; avol; err)⟩ (synced(avol0) ∧ adr = adr0 ∧ m0 = m1 ∧ nx = nx0 ∧ lpt0 = lpt ∧ avol0 ↓ avol ∧ ns = ns0), buffered(m) = bleb

And obtained the following new goals

Proof step 3:
# lpt = # avol, buffered(m) ≠ bleb, m < # avol, awbuf-inv(avol, bleb), synced(avol0), synced(avol), avol0 ↓ avol ⊦ ⟨awbuf_remap#(m, adr0, m1, nx0, lpt, ns0, bleb, isbuf; avol; err)⟩ (avol0 ↓ avol)
