Proof step 14 from proof crash-neutral-read-vidhdr (previous step)

apebs[n] = mkpeb(aehdr, avhdr0, buf, m, false), n < # apebs, ubi-io-inv(apebs) ⊦ ∃ bitflips. ⟨if EIO = ESUCCESS then avhdr := apebs[n].vidhdr else avhdr := ?⟩ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 15:
apebs[n] = mkpeb(aehdr, avhdr0, buf, m, false), n < # apebs, ubi-io-inv(apebs) ⊦ ⟨avhdr := ?⟩ true
