-Document counts include canonical rows from both projects. Polygon counts deduplicate places per language and require non-empty text: Wikipedia uses the `polygon_articles` link table, while Wikivoyage joins through the shared Wikidata QID.
+Document counts include canonical rows from both projects. Polygon counts are unique `(osm_type, osm_id)` polygon identities per language and require successfully extracted (`fetch_status=ok`) trimmed non-empty `full_text`. Canonical links use the `polygon_articles` identity join; legacy Wikivoyage links use the shared Wikidata QID fallback.
