Proof step 26 from proof inv-commit (previous step)

# buf = EB_PAGE_SIZE, # lpt0 = # avol, # lpt = # avol, err = err0, ebm-vol-inv(avol), bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m1, m2), avol[bleb.leb], rofs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ err = ESUCCESS, (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m1, m2), avol[bleb.leb], true)) ∧ # lpt = # avol

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 27:
# lpt = # avol, # lpt0 = # avol, # buf = EB_PAGE_SIZE, avol[bleb.leb] = mapped(buf0), bleb.leb < # avol, ebm-vol-inv(avol), wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), rofs), ⌊err0⌋ ⊦ bleb = nobuffer, wbuf-cons(mkwbuf(buf, m1, m2), mapped(buf0), true)
