Proof step 46 from proof recovery (previous step)

avol = abs(avols0[default-volid]), ebm-cons(avols1), ebm-cons(avols0), ebm-vol-inv(abs(avols1[default-volid])), default-volid ∈ avols1, default-volid ∈ avols0, avols1 ⊆ avols0 ⊦ ∃ err0. (⌊err0⌋ ∨ err0 = ESUCCESS) ∧ ⟨err := err0; if err ≠ ESUCCESS then avol := ?⟩ (avol = abs(avols0[default-volid]) ∧ ESUCCESS = err)

User applied rule exists right

And obtained the following new goals

Proof step 47:
avol = abs(avols0[default-volid]), ebm-cons(avols0), ebm-cons(avols1), ebm-vol-inv(abs(avols1[default-volid])), default-volid ∈ avols0, default-volid ∈ avols1, avols1 ⊆ avols0 ⊦ (⌊ESUCCESS⌋ ∨ ESUCCESS = ESUCCESS) ∧ ⟨err := ESUCCESS; if err ≠ ESUCCESS then avol := ?⟩ (avol = abs(avols0[default-volid]) ∧ ESUCCESS = err)
