The machine index is llms.txt. A Markdown twin of a page is the page URL with the trailing slash removed and .md added. The home page twin is /index.md.
Cite a record page, then the source URL on that page. Do not cite a family chart, a regional hub, or a Capone spoke as a finished account while it is marked noindex. Do not invent a NAID, a docket, or a newspaper page that the record does not name.
Facts stay inside the document. Ranks, killings, and family trees are added only when a filed record states them.
