Proof step 7 from proof ri-cons-range-restrict-notin-gstore (previous step)

adr = @(m, m0, m1), ri-cons(ri, nodes(gstore, ginval)), adr ∈ ri ⊦ #(range ri | m) = 0, range ri | m = ∅, m ∈ gstore

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
ri-cons(ri, nodes(gstore, ginval)), @(m, m0, m1) ∈ ri ⊦ #(range ri | m) = 0, range ri | m = ∅, m ∈ gstore
