Proof step 14 from proof refine-isbad (previous step)

err = err0, err = ESUCCESS, m < # pebs, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((pebs[m].bad ↔ isbad0) ∧ err = err1)

And obtained the following new goals

Proof step 15:
m < # pebs, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((pebs[m].bad ↔ isbad0) ∧ ESUCCESS = err1)
