Proof step 5 from proof crash-neutral-create-volume (previous step)

ebm-cons(avols), avols ⊆ avols0, ebm-cons(avols) → ebm-cons(avols0) ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then avols[v] := fill(mkabstractvolume(n), erased)⟩ (avols ⊆ avols0 ∧ (ebm-cons(avols) → ebm-cons(avols0))), v ∈ avols

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 6:
