Proof step 6 from proof inv-create-volume (previous step)

ebm-cons(avols) ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then avols[v] := fill(mkabstractvolume(n), erased)⟫ ebm-cons(avols), v ∈ avols

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 7:
ebm-cons(avols), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; if err = ESUCCESS then avols[v] := fill(mkabstractvolume(n), erased)⟫ ebm-cons(avols), v ∈ avols
Proof step 31:
ebm-cons(avols) ⊦ v ∈ avols, ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS
