Proof step 21 from proof nodes-except-refsize (previous step)

gstore0[m] = groupblock(gndx, lax, m2), gstore1 =○refsize gstore0, m ∈ gstore0, @(m0, m1) ∈ lax ⊦ @(m, m0, m1) ∈ gstore1, m ∈ ginval

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 22:
⊦ adr ∈ gstore ↔ adr.lnum ∈ gstore ∧ @(adr.pos, adr.size) ∈ gstore[adr.lnum].ladrlist
Proof step 23:
gstore0[m] = groupblock(gndx, lax, m2), gstore1 =○refsize gstore0, @(m0, m1) ∈ lax, m ∈ gstore0 ⊦ m ∈ ginval, @(m, m0, m1).lnum ∈ gstore1 ∧ @(@(m, m0, m1).pos, @(m, m0, m1).size) ∈ gstore1[@(m, m0, m1).lnum].ladrlist

Rule argument
