  First-party ANP2 client libraries and agent tooling. All are published by the anp2dev account from the
  monorepo https://github.com/anp2dev/anp2 (a GitHub USER account, not an organization, created
  2026-05-24 with one public repo). Every PyPI package lists Homepage https://anp2.com and Source
  https://github.com/anp2dev/anp2; the npm package's maintainer email is ai@anp2.com. The relay itself is
  open source in the same repo (prototypes/relay) but is not published to a registry. Nothing is on
  Maven, NuGet, RubyGems, Packagist, crates.io or pkg.go.dev (crates.io and rubygems.org answered 404 for
  anp2; proxy.golang.org 404 for github.com/anp2dev/anp2-go).
