-- 0020_site_name_from_page: recipes.site_name now holds only the name a
-- recipe page gives its site (its publisher's name or og:site_name), and is
-- null when the page names none; a client is credited with the link's host
-- only when dinners.SourceOf finds the link safe to show. Before this, a
-- page naming no site was stored under the host of the URL it was served
-- from, which may carry a personal token, and nothing recorded which a
-- stored name was. A stored name that could be a host — a dotted host name
-- or an IP address, spelled only in host characters — is cleared here, so
-- every stored name is one a page gave. A site that names itself as a
-- domain, such as "Food.com", loses its stored name with them until its
-- recipe is fetched again, and is credited by its link's host meanwhile
-- when the link is safe.
--
-- Idea job results stored before sources were made safe hold the grounded
-- recipe's site name as it was stored, and are cleared the same way: an
-- idea's stored site name is shown as it stands. The ideas array is
-- rebuilt from a plain scan of json_each, which yields its elements in
-- array order, so the ideas keep their order (sqlc's parser refuses an
-- ORDER BY inside json_group_array).
