    Elasticsearch REST API authentication is per-cluster. HTTP Basic and API
    keys are the primary programmatic mechanisms; the security layer also
    supports bearer/service tokens, PKI (mutual TLS), and enterprise SSO realms
    (SAML, OIDC, Kerberos, LDAP/Active Directory). Authorization is
    role-based (RBAC) via cluster and index privileges, not OAuth scopes.
