Parts only some setups need. Nothing else depends on them; offer each one separately, after the basic install works.

• identity.md corporate login (Okta, Entra ID, Google Workspace) and user to team mapping.

• decision-models.md connector to classification models that label events cheaply; the owner picks the vendor or a local model.
