      description: Session cookie issued after an interactive login against the institute OAuth 2 server at https://oauth.iitd.ac.in/. That server publishes no OpenID Connect discovery document, no authorization or token endpoint documentation and no scope vocabulary — verified 404 on /.well-known/openid-configuration and /.well-known/oauth-authorization-server on 2026-08-30 — so the flow cannot be described further from public evidence.
