Recorded per source; the attribution line is shown on every page that uses a value from this source.
Quirks recorded by the connector author (access method, limits, robots exceptions).
about.fb.com/feed (10 items, mostly product news) filtered on title/summary; the Meta Data Centers blog (datacenters.atmeta.com — "Kansas City, we are online!", "Hello, Bowling Green!", grants) has no working RSS (/feed/ returns the HTML home page) but publishes a Yoast post-sitemap.xml (~68 dated posts). discovery.include keeps only dated article URLs so static pages (community-grants, funds) are not turned into news. Both hosts allow crawling.
Current provenance rows by entity type, and archived documents by page type.
How this source is read.
