Proof step 17 from proof inv-remap (previous step)

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

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 18:
m < # avols0[default-volid], ebm-cons(avols0), default-volid ∈ avols0, ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; avols := avols0[default-volid, avols0[default-volid][m, unmapped]]; if err = ESUCCESS then avols[default-volid][m] := mapped(emptyleb, 0)⟫ (default-volid ∈ avols ∧ ebm-cons(avols))
Proof step 23:
m < # avols0[default-volid], ebm-cons(avols0), default-volid ∈ avols0 ⊦ ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS
