Nine roles reached their MCP surface as the deployment administrator or with
an account password kept beside the account in credentials. A Moodle site
admin bypasses every capability check, a Nextcloud app password is not
scopable, a Gitea token reads every private repository, and a GitLab token on
root reads every private project. Each role now declares its own principal in
meta/users.yml and provisions it, so the exposed surface is what the service
role permits. jellyfin, zammad and snipe-it kept their account but took its
password from a credential named token; they read the registry too.
