Primary sources and visible limitations
Statutes, regulations, government agencies, court material, and federal medical or safety sources are preferred. A source is linked near the relevant subject or included in the official-source library, and the page explains when the source supplies background rather than a case-specific conclusion.
Commercial sources are not used to manufacture consensus. When a company is the primary source for its own policy, product, or coverage statement, that relationship is apparent from the publisher name and link.
