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

m < # avols[v], ebm-cons(avols), v ∈ avols, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪if err0 = ESUCCESS then avols[v][m] := mapped(emptyleb, 0)⟫ ebm-cons(avols), avols[v][m].mapped?

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 9:

Proof step 10:
