Proof step 19 from proof inv-remap (previous step)

m < # avols0[default-volid], ebm-cons(avols0), default-volid ∈ avols0, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪avols := avols0[default-volid, avols0[default-volid][m, unmapped]]; if err0 = ESUCCESS then avols[default-volid][m] := mapped(emptyleb, 0)⟫ (default-volid ∈ avols ∧ ebm-cons(avols))

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
