Proof step 9 from proof inv-read-vidhdr (previous step)

apebs[n] = mkpeb(aehdr, avhdr0, buf, m, false), n < # apebs, ubi-io-inv(apebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; bitflips := ?; if err = ESUCCESS then avhdr := apebs[n].vidhdr else avhdr := ?⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
