Sources are selected for disclosure relevance, sourcing clarity, public-record value, and editorial usefulness. A trust score does not mean agreement; it reflects how clearly a source identifies information, links to records, corrects errors, and contributes to the public disclosure record.
Official records, mainstream reporting, scientific research, independent commentary, and archives are labeled separately. Claims can appear on the site without being endorsed when they are useful to track, contextualize, or compare against official responses.
