Proof step 10 from proof abs-log-new (previous step)

gstore[lnum] = groupblock(gndx, lax, m), ax.toSet ∩ abs-log(nx0, gstore).toSet = ∅, ginval ∩ elems nx0 = ∅, new(ax, nodes(gstore, ginval)), lnum ∈ gstore, adr ∈ ax, adr ∈ lax.to-adr(lnum), elems nx0 ⊆ dom gstore ⊦ #(ax.toSet ∩ (lax.to-adr(lnum)).toSet) = 0, #(ax.toSet ∩ ((lax.to-adr(lnum)).toSet ∪ abs-log(nx0, gstore).toSet)) = 0, lnum ∈ ginval

And obtained the following new goals

Proof step 11:
⊦ new(log, fs) ↔ (∀ adr. adr ∈ log → ¬ adr ∈ fs)
Proof step 12:
gstore[lnum] = groupblock(gndx, lax, m), ginval ∩ elems nx0 = ∅, ax.toSet ∩ abs-log(nx0, gstore).toSet = ∅, adr ∈ lax.to-adr(lnum), adr ∈ ax, lnum ∈ gstore, elems nx0 ⊆ dom gstore, ∀ adr. adr ∈ ax → ¬ adr ∈ nodes(gstore, ginval) ⊦ #(ax.toSet ∩ ((lax.to-adr(lnum)).toSet ∪ abs-log(nx0, gstore).toSet)) = 0, #(ax.toSet ∩ (lax.to-adr(lnum)).toSet) = 0, lnum ∈ ginval

Rule argument
