Your question is Event-Driven Streaming Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Design an asynchronous event-driven architecture using Python to handle real-time streaming completions and webhook notifications at scale.
Explain how you would use the OpenAI Responses API streaming interface, asynchronous workers, durable event transport, and webhook delivery services. Cover event schemas, ordering, idempotency, backpressure, retries, replay, observability, security, and graceful degradation. Include representative Python code and describe how the design scales across processes, containers, and availability zones.
