No OAuth / OpenID Connect provider here
https://sovnik.com publishes machine-readable discovery (including
/.well-known/openid-configuration
and /.well-known/oauth-authorization-server)
so agents can see required metadata fields. This origin does not issue access tokens or run an authorization server for third-party clients.
Public resources (sitemap, agent quiz JSON, API catalog, etc.) are anonymous and read-only. App sign-in uses first-party mobile/web SDKs, not these URLs.
