Proof step 18 from proof recovery (previous step)

ebm-cons(avols0), ebm-cons(avols1), ebm-vol-inv(abs(avols1[default-volid])), default-volid ∈ avols1, avols1 ⊆ avols0, ⌊err1⌋ ⊦ ⟨err := err1; if err ≠ ESUCCESS then avol := ?⟩ (avol0 = avol ∧ err1 = err)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 19:
