Proof step 8 from proof inv-create-volume (previous step)

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

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 9:
err0 = ESUCCESS, ebm-cons(avols), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪avols[v] := fill(mkabstractvolume(n), erased)⟫ ebm-cons(avols), v ∈ avols
Proof step 30:
ebm-cons(avols), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip⟫ ebm-cons(avols), err0 = ESUCCESS, v ∈ avols

Rule argument

pos: right 1
