Domain resolution covers only entities Wikidata links to an LEI and an official website (21688 domain rows, skewed to large and listed companies), matched exactly against the registrable domain, so a subdomain is a miss. A domain absent here is absent from this map only, not proof the company lacks an LEI; a miss is a miss from THIS snapshot only. official_website is present only on domain answers; it is null on name and LEI answers, which are read from shards that carry no website column. Answers are served from R2 shards each verified against a manifest whose sha256 is this snapshot_sha256; refresh is a new vintage prefix and a re-pin, never a live fetch.",
