	TraceAttributes(*http.Request) []attribute.KeyValue
	// CorrelatingToolCallID returns the ID of a tool call result submitted
	// in the request, if present. This is used to correlate the current
	// interception back to the previous interception that issued those tool
	// calls. If multiple tool use results are present, we use the last one
	// (most recent). Both Anthropic's /v1/messages and OpenAI's /v1/responses
	// require that ALL tool results are submitted for tool choices returned
	// by the model, so any single tool call ID is sufficient to identify the
	// parent interception.
