Proof step 17 from proof abs-istore-set-refsize (previous step)

lpt[n] = mklp(n0, m2, LP_INDEX_NODES, n4), istore[n] = indexblock(indx1, lax1, n0), n < # lpt, abs-leb(avol[n], indexblock(indx1, lax1, n0), mklp(n0, m2, LP_INDEX_NODES, n4)), n ∈ istore ⊦ avol[n].mapped? ∧ abs-nodes (avol[n].data, indexblock(indx1, lax1, m1).indlist, indexblock(indx1, lax1, m1).ladrlist, mklp(m1, m2, LP_INDEX_NODES, m3).size = LEB_SIZE) ∧ (mklp(m1, m2, LP_INDEX_NODES, m3).size ≠ LEB_SIZE → mklp(m1, m2, LP_INDEX_NODES, m3).size = # avol[n].data)

And obtained the following new goals

Proof step 18:
istore[n] = indexblock(indx1, lax1, n0), lpt[n] = mklp(n0, m2, LP_INDEX_NODES, n4), n < # lpt, abs-leb(avol[n], indexblock(indx1, lax1, n0), mklp(n0, m2, LP_INDEX_NODES, n4)), n ∈ istore ⊦ avol[n].mapped? ∧ abs-nodes(avol[n].data, indx1, lax1, m2 = LEB_SIZE) ∧ (m2 ≠ LEB_SIZE → m2 = # avol[n].data)
