Type Alias ModelResolver 

pub type ModelResolver<R> = Arc<dyn Fn(&CompletionResponse<R>) -> Option<String> + Send + Sync>;

Caller-supplied resolver that pulls the actual model identifier out of a provider response. Useful for routed providers (OpenRouter, Bedrock model-routing, vendor multi-model endpoints) where the model recorded at hook construction is a logical alias and the response’s raw payload carries the concrete model that served the request.

When set and the resolver returns Some(model), that value is stamped on prompt.completed instead of TelemetryHookConfig::model.
