Proof step 36 from proof refine-isbad (previous step)

m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then isbad := apebs[m].bad else isbad := ?⟩ ((isbad1 ↔ isbad) ∧ err0 = err)

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 37:
