Primary-source discipline
Each entry begins with a dossier assembled from the public record: court opinions and filings, peer-reviewed research, inspector-general reports, statutes, campaign-finance databases, official agency publications, FOIA-derived datasets, and named-byline investigative journalism at tier-1 outlets — the New York Times, Wall Street Journal, Washington Post, Reuters, Associated Press, Bloomberg, ProPublica, NPR, PBS Frontline, The New Yorker, CBS News, CNN, and their equivalents.
No single aggregator is ever cited in isolation. Wikipedia, social media, and unsigned blogs never appear on a source strip — only on the cutting-room floor of the research process, as pointers to the primary sources that do make it through.
