Proof step 1 from proof inv-recover (conclusion)

avols ⊆ avols0, ebm-cons(avols) → ebm-cons(avols0), v ∈ avols, v = default-volid, ebm-cons(avols) ⊦ ⟪ebm_vol_recover#(; avols0; v0, err)⟫ (err = ESUCCESS → v0 ∈ avols0 ∧ v0 = default-volid ∧ ebm-cons(avols0))

System applied rule normalize

And obtained the following new goals

Proof step 2:
v = default-volid, ebm-cons(avols), v ∈ avols, avols ⊆ avols0, ebm-cons(avols) → ebm-cons(avols0) ⊦ ⟪ebm_vol_recover#(; avols0; v0, err)⟫ (err = ESUCCESS → v0 ∈ avols0 ∧ v0 = default-volid ∧ ebm-cons(avols0))
