Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 89:
apebs[m2] = mkpeb(aehdr1, avhdr, buf0, m1, false), pebs[m2] = mkpeb(buf1, m0, false), err = err1, m2 < # pebs, m2 < # apebs, abs(pebs, apebs), abs-peb(mkpeb(buf1, m0, false), mkpeb(aehdr1, avhdr, buf0, m1, false)), mtd-cons(pebs), ubi-io-inv(apebs), EB_PAGE_SIZE ≤ PEB_SIZE, ⌊err1⌋ ⊦ ⟨aehdr := ?⟩ (aehdr0 = aehdr ∧ (bitflips0 ↔ bitflips0) ∧ err1 = err), subarray(buf1, 0, EB_PAGE_SIZE) = emptypage

Rule argument

pos: right 1
