The scan was scoped to the stored series_id, which since #89 is the Series
slug while chapter addresses carry a Chapter Slug, so on divergent novels it
matched zero anchors. The Poll refreshes lnw Series on a one-hour cooldown,
four times faster than the client throttle, so the scan optimised nothing
while its unscoped alternative would have let a public wpdiscuz comment
anchor write a Latest Chapter every Reader of the row shares. Delete the
adapter method; the shared computation yields null for an adapter without a
scanner, and the background refresh skips the Site before the due filter so
no Series page is fetched and no freshness timestamp is recorded.
