Proof step 8 from proof crash-neutral-create-volume (previous step)

ebm-cons(avols), ebm-cons(avols0), avols ⊆ avols0, ¬ v ∈ avols ⊦ ⟨err := EIO; if err = ESUCCESS then avols[v] := fill(mkabstractvolume(n), erased)⟩ (avols ⊆ avols0)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
