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

apebs[n] = mkpeb(aehdr0, avhdr, buf, m, false), n < # apebs, ubi-io-inv(apebs) ⊦ ∃ bitflips. ⟨if EIO = ESUCCESS then aehdr := apebs[n].echdr else aehdr := ?⟩ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 15:
apebs[n] = mkpeb(aehdr0, avhdr, buf, m, false), n < # apebs, ubi-io-inv(apebs) ⊦ ⟨aehdr := ?⟩ true
