Direction is the change in each trope’s share of the lane between the last 12 weeks and the 12 before — never a raw weekly move. “Not called” means the two bands hold fewer than 30 mentions between them and we will not pretend otherwise. Tagged titles are counted across our whole registry, not just this lane.
