28"""No-op provider: keeps the OSS default frictionless.
Selected when ``settings.auth_mode == "none"``. The middleware is not wired
when this provider is active, so its methods only run if something
mistakenly registers it as an active provider — they raise loudly to surface
that bug rather than silently letting requests through unauthenticated.
