Proof step 16 from proof initialization (previous step)

err = ESUCCESS, mtd-cons(pebs), ubi-io-initial(pebs) ⊦ ⟨choose apebs0 with ubi-io-initial(apebs0) in apebs := apebs0⟩ (abs(pebs, apebs) ∧ ESUCCESS = err)

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 17:
err = ESUCCESS, mtd-cons(pebs), ubi-io-initial(pebs) ⊦ ∃ apebs0. ubi-io-initial(apebs0) ∧ ⟨apebs := apebs0⟩ (abs(pebs, apebs) ∧ ESUCCESS = err)
