    ETSI is a standards body, so most of the harvested specs describe a protocol, not a hosted
    service, and carry no security scheme at all — the deployer supplies one. Three surfaces do
    declare real authentication: the ETSI OpenSlice TM Forum Open APIs (OAuth 2.0 authorization
    code against a live Keycloak realm), OpenCAPIF (OAuth 2.0 client credentials, token URL
    templated per deployment), and the OpenSlice CAMARA QoD Provisioning add-on (OpenID Connect
    plus a bearer scheme for notification sinks, matching the CAMARA authorisation model).

    3GPP CAPIF TS 29.222 as implemented by ETSI OpenCAPIF. The token URL is a deployment
    template — the CAPIF core function issues the token after an API invoker is onboarded.

    CAMARA authorisation model. The discovery URL in the published document is the CAMARA
    template placeholder, to be replaced by the operator's own issuer at deployment. No CIBA
    grant is declared in this document.
