- postgres replaces keycloak-db and holds a keycloak and a mancala database,
each with its own user, created by apps/postgres/init
- valkey with an append-only file for live game state and caches
- backend gets DATABASE_URL and VALKEY_URL
- Custom authenticator creates and logs in a guest user when the
authorization request has guest=true; other requests get the login form
- Scheduled task removes guests with no remaining sessions
- Realm export with mancala-web PKCE client, guest role and guest-aware
browser flow (verify profile disabled so guests are not asked for details)
- Dockerfile building the extension into a Keycloak 26.7.5 image
- Keycloak and Postgres in compose; nginx proxies auth.playmancala.app
and rate limits the auth endpoint
- Integration tests run the extension and realm in a Keycloak container
