How we research: evidence first. Every mystery in this archive starts with what was seen, what was recorded, and what can be checked — and we say plainly what remains unknown. We work only from published sources: books, peer-reviewed papers, declassified files, contemporary news reports, and official records. Each article lists its sources so you can check them yourself. Where sources disagree, we say so — we do not pick the version that makes a better story. We label every claim. Verified means it is supported by primary evidence or multiple independent sources. Leads means it is plausible but unconfirmed. Rumour means it is widely repeated without reliable evidence. Reader accounts are always labelled as reader accounts, never as verified fact. If new evidence changes a story, we update the article and note the change.
