Facts we can show our work on
Audio is persuasive, which makes it dangerous. A confident voice can make a wrong date sound true, so we built the guardrails first: every specific claim in a script has to trace back to an official site, a national park service, a museum archive or a public record, and the sources travel with the script.
Nothing publishes on a machine's say-so. A human reads every script before it is recorded, and the recording itself is transcribed back and compared to the script word for word — if the narration drifted, the file never reaches you. Where the record is genuinely contested, the guide says so instead of picking the better story.
