Proof step 14 from proof abs-istore-replay-lpt-unchanged (previous step)

# avol0 = # avol1, # lpt = # avol1, replay-lpt(lpt, nx, # avol1)[n] = mklp(m, m1, LP_INDEX_NODES, m2), istore[n] = indexblock(indx, lax, m), lpt[n] = mklp(m0, m3, lpf, m4), n < # avol1, abs-leb(avol1[n], indexblock(indx, lax, m), mklp(m, m1, LP_INDEX_NODES, m2)), n ∈ istore, n ∈ nx ∨ m0 ≠ 0 ∨ lpf = LP_FREE → avol0[n] = avol1[n] ⊦ m = 0, abs-leb(avol0[n], indexblock(indx, lax, m), mklp(m, m1, LP_INDEX_NODES, m2))
