Proof step 8 from proof fwd-in-istore-lpt (previous step)

istore[n] = indexblock(indx, lax, m), lpt[n] = mklp(m0, m1, lpf, m2), n ∈ istore, ∀ n. (n < # lpt ∧ lpt[n].flags = LP_INDEX_NODES ↔ n ∈ istore) ∧ (n ∈ istore → abs-leb(avol[n], istore[n], lpt[n]) ∧ lpt[n].ref-size = istore[n].ref-size) ⊦ n < # lpt ∧ m0 = m ∧ lpf = LP_INDEX_NODES
