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

# lpt0 = # avol, adr = adr0, lpt = lpt0, m = m0, m1 = EB_PAGE_SIZE, ns = ns0, plog = plog0, ebm-vol-inv(avol), wbuf-cons(bleb, wbuf, avol, rofs), avol ⊆ avol0 ⊦ ⟪wbuf_recover#(; adr1, m2, ns1, log, lpt1, wbuf0, m3, adr, m, plog, avol0, lpt, ns, bleb0, rofs0; err)⟫ (err = ESUCCESS → wbuf-cons(bleb0, wbuf0, avol0, rofs0) ∧ m3 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol0) ∧ # lpt = # avol0)

And obtained the following new goals

Proof step 3:
# lpt0 = # avol, # wbuf.content = EB_PAGE_SIZE, ebm-vol-inv(avol), avol ⊆ avol0, bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs) ⊦ ⟪wbuf_recover#(; adr1, m2, ns1, log, lpt1, wbuf0, m3, adr, m, plog, avol0, lpt0, ns, bleb0, rofs0; err)⟫ ( err = ESUCCESS → # wbuf0.content = EB_PAGE_SIZE ∧ (bleb0 ≠ nobuffer → bleb0.leb < # avol0 ∧ wbuf-cons(wbuf0, avol0[bleb0.leb], rofs0)) ∧ m3 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol0) ∧ # lpt0 = # avol0)

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)
