# avol0 = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, adr = adr0, lpt = lpt0, m = m0, ns = ns0, plog = plog0, abs(avol, bleb, mkwbuf(buf, m2, m1), avol0, rofs), awbuf-inv(avol, bleb), ebm-vol-inv(avol0), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m2, m1), avol0[bleb.leb], rofs) ⊦ abs(avol, bleb, mkwbuf(buf, m2, m1), avol0, true) ∧ (true ↔ true)

Proof step 10:
# avol0 = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, avol0[bleb.leb] = mapped(buf0), bleb.leb < # avol, abs(avol, bleb, mkwbuf(buf, m2, m1), avol0, rofs), awbuf-inv(avol, bleb), ebm-vol-inv(avol0), wbuf-cons(mkwbuf(buf, m2, m1), mapped(buf0), rofs) ⊦ bleb = nobuffer, abs(avol, bleb, mkwbuf(buf, m2, m1), avol0, true)
