Proof step 14 from proof crash-neutral-markbad (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), apebs0 = apebs, n < # apebs, ubi-io-inv(apebs) ⊦ ⟨if EIO = ESUCCESS then apebs[n].bad := true⟩ (apebs0 = apebs)

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 15:
apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), apebs0 = apebs, n < # apebs, ubi-io-inv(apebs) ⊦ ⟨skip⟩ (apebs0 = apebs)

Rule argument

pos: right 1

Used simplifier rules: ⊦ ESUCCESS ≠ EIO; (s)
