Source: https://longwatch.dev/.well-known/ai-catalog.json, this publisher's own file. Identifiers are reproduced exactly as published. Note: this is the pre-v0.91 path. The specification renamed the manifest to /.well-known/ard.json, and most of the ecosystem still serves the older name. Of the resources listed, 1 have been probed for reachability. "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.
