Proof step 8 from proof inv-remap (previous step)

m < # avol, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪if err0 = ESUCCESS then avol[m] := mapped(mkbuf(0)) else {skip or avol[m] := unmapped}⟫ ebm-vol-inv(avol)

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 9:
err0 = ESUCCESS, m < # avol, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪avol[m] := mapped(mkbuf(0))⟫ ebm-vol-inv(avol)
Proof step 10:
m < # avol, ebm-vol-inv(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪skip or avol[m] := unmapped⟫ ebm-vol-inv(avol), err0 = ESUCCESS
