Proof step 3 from proof adr-in-ri-notin-nodes (previous step)

ri-cons(ri, nodes(gstore, ginval)), adr ∈ ri ⊦ adr ∈ gstore ∧ ¬ adr.lnum ∈ ginval

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ ri-cons(ri, fs) ↔ (∀ key. key ∈ ri → ri[key] ∈ fs ∧ key-cons(key, fs[ri[key]]))
Proof step 5:
adr ∈ ri, ∀ key. key ∈ ri → ri[key] ∈ nodes(gstore, ginval) ∧ key-cons(key, nodes(gstore, ginval)[ri[key]]) ⊦ adr ∈ gstore ∧ ¬ adr.lnum ∈ ginval

Rule argument
