Proof step 30 from proof initialization (previous step)

⌊err⌋ ⊦ ⟨apersistence_io_format#(# lpt0, LEB_SIZE, lpt0, adr1, m3; ; adr2, m6, plog, avol1, lpt1, ns0, err0)⟩ (adr = adr2 ∧ m1 = m6 ∧ log0 = plog ∧ avol0 = avol1 ∧ lpt2 = lpt1 ∧ ns = ns0 ∧ err = err0)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals
