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

⊦ ⟪wbuf_format#(# lpt, LEB_SIZE, lpt, adr, m1; wbuf, m2, adr0, m3, plog, avol, lpt0, ns, bleb, rofs; err)⟫ ( err = ESUCCESS → # wbuf.content = EB_PAGE_SIZE ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ m2 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol) ∧ # lpt0 = # avol)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 3:
adr = adr1, adr0 = adr2, lpt = lpt1, lpt0 = lpt2, m = m4, m0 = m5, m2 = LEB_SIZE, m3 = # lpt2 ⊦ ⟪if m3 = # lpt0 ∧ m2 = LEB_SIZE then {apersistence_io_format#(m3, m2, lpt0, adr0, m1; ; adr, m, plog, avol, lpt, ns, err); if err = ESUCCESS then {apersistence_io_get_page_size#(adr, m, plog, avol, lpt, ns; ; m0); bleb := nobuffer; wbuf.content := mkbuf(m0); rofs := false}} else abort⟫ ( err = ESUCCESS → # wbuf.content = EB_PAGE_SIZE ∧ (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(wbuf, avol[bleb.leb], rofs)) ∧ m0 = EB_PAGE_SIZE ∧ ebm-vol-inv(avol) ∧ # lpt = # avol)
