"""Auto-routed auxiliary calls on xAI OAuth refresh the grant after a 403 bad-credentials (#84845).

A plugin/hook ``call_llm`` with no provider override inherits the main ``xai-oauth`` route as
``resolved_provider == "auto"``; the refresh rung must still resolve the concrete backend from the
client's host so the expired bearer is refreshed and retried instead of benching the only grant.
An auto client tagged with the API-key ``xai`` backend must NOT borrow that row: an XAI_API_KEY 401
would otherwise spend a stale ``xai-oauth`` grant's refresh rotation and silently switch routes.
