Proof step 5 from proof lebs-dom-remove-refsize0 (previous step)

inv(gstore \ ginval), refsize-cons(gstore, range ri), ri-cons(ri, nodes(gstore ↓, ginval)) ⊦ ∀ n. n ∈ ri.lebs → n ∈ dom remove-refsize0(gstore)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Rule argument

Additional information

Used simplifier rules: ⊦ n ∈ dom gstore ↔ n ∈ gstore; (s)% ⊦ n ∈ ri.lebs ↔ (∃ adr. adr.lnum = n ∧ adr ∈ ri); (s)
