Proof step 9 from proof crash-neutral-create-volume (previous step)

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

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 10:
ebm-cons(avols), ebm-cons(avols0), avols ⊆ avols0 ⊦ ⟨skip⟩ (avols ⊆ avols0), v ∈ avols

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ ESUCCESS ≠ EIO; (s)
