I have Tazama Rule Studio (TRS) running (e.g., at localhost:5176) but can't log in with any of the default Keycloak users. What am I missing?

The default Keycloak users for TRS are trs-approver@tazama.org, trs-editor@tazama.org, and trs-publisher@tazama.org, with default password “password” (change it after first login). If login still fails, Rule Studio is likely missing its prerequisites: TRS is an extension on top of the Tazama core and, at minimum, requires the Tazama core services (deployed via tazama-stack), the Connection Studio (TCS), and the Event Monitoring Service to be running. Without these, TRS cannot function even if the service itself is up, since rules constructed in TRS need a valid configuration built through TCS - a network map, a typology, and a rule config must already exist in the configuration database. If you're just getting started, deploy the Full Stack option first, confirm everything is linked, and only then pick and choose individual extensions.
