Proof step 35 from proof inv-format (previous step)

err = err0, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪if err = ESUCCESS then {v := default-volid; ebm_create_volume#(v, m; avols; err)}⟫ (err = ESUCCESS → default-volid ∈ avols ∧ v = default-volid ∧ ebm-cons(avols)), err = ESUCCESS

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 36:
