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

# lpt0 = # avol, # lpt = # avol, ebm-vol-inv(avol), wbuf-cons(bleb, wbuf, avol, rofs) ⊦ ⟪wbuf_commit#(lpt0, adr, m, avol; ns, adr0, m0, plog, lpt, ns0, rofs; err)⟫ (wbuf-cons(bleb, wbuf, avol, rofs) ∧ # lpt = # avol)

And obtained the following new goals

Proof step 3:
# lpt = # avol, # lpt0 = # avol, # wbuf.content = EB_PAGE_SIZE, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_commit#(lpt0, adr, m, avol; ns, adr0, m0, plog, lpt, ns0, rofs; err)⟫ ((bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ # lpt = # avol)

Rule argument

Additional information

Used simplifier rules: ⊦ wbuf-cons(bleb, wbuf, avol, rofs) ↔ # wbuf.content = EB_PAGE_SIZE ∧ ( bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)); (s)
