Editorial policy

Desk notes prioritize files a stranger can open. Marketing claims without paperwork are marked thin. We do not publish medical advice or human-use guidance.

Updates

Pages show published and updated dates. Material catalog changes can move OpenFile grades on the next pass.

Corrections

Send dated certificates and URLs via the contact page. Evidence beats pressure.

Independence

OpenFile grades are not for sale. Affiliations are listed on /policy/affiliations.
