Proof step 2 from proof crash-neutral-create-volume (previous step)

ebm-cons(avols), avols ⊆ avols0, ebm-cons(avols) → ebm-cons(avols0) ⊦ ⟨ebm_create_volume#(v, n; avols; err)⟩ (avols ⊆ avols0 ∧ (ebm-cons(avols) → ebm-cons(avols0))), v ∈ avols

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 3:
ebm-cons(avols), avols ⊆ avols0, ebm-cons(avols) → ebm-cons(avols0) ⊦ ⟨if ¬ v ∈ avols then {fail_or_success#(; ; err); if err = ESUCCESS then avols[v] := fill(mkabstractvolume(n), erased)} else abort⟩ (avols ⊆ avols0 ∧ (ebm-cons(avols) → ebm-cons(avols0))), v ∈ avols

Rule argument
