Source policy
Every answer is checked against a named source. We prioritize government, scientific, academic, museum, and other authoritative references, and we do not publish a value that cannot be verified.
Review and corrections
Each item keeps its source name and direct URL. When a source changes or a correction is needed, an editor can revise the value and explanation without replacing the challenge or its completion record.
