Source: https://canonicalhash-production.up.railway.app/.well-known/ard.json, this publisher's own file. Identifiers are reproduced exactly as published. None of these endpoints has been probed for reachability yet, so nothing here says whether they answer. "Answers" and "no response" describe only whether an endpoint replied when last probed: services go down and come back, and an entry is demoted rather than removed. None of this is a trust, quality or safety rating.
