Proof step 7 from proof inv-get-block-free-size (previous step)

remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(gstore1), inv(gstore2 \ ginval2), ri-inj(fi1), ri-inj(fi2) ⊦ dups(nx), ∃ n0. n0 ≤ LEB_SIZE

Heuristic quantifier closing applied rule exists right

And closed the goal!
