Proof step 7 from proof inv-add-log-leb (previous step)

# lpt = # avol, m = m1, m0 = m2, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪if err0 = ESUCCESS then plog := plog + m0⟫ true

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 8:
# lpt = # avol, err0 = ESUCCESS, m = m1, m0 = m2, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪plog := plog + m0⟫ true
Proof step 9:
# lpt = # avol, m = m1, m0 = m2, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip⟫ true, err0 = ESUCCESS
