This v1 history holds the route, scanner method, browser, device, conditions, catalog, Brave-list source and list count constant. It does not hold the filter-list snapshot date constant: a changed snapshot can support raw and catalogued-service differences, but never a Shields or detector delta, so a difference here is not evidence that blocking behaviour changed. Differences can still reflect site experiments, ad rotation, caching or bot detection.
