عرض عملي: مساعد دعم الطلبات يصمد أمام انقطاع المزوّد

خطوة بخطوة

1. Map the assistant's dependencies: model provider, retrieval, order API.
2. Define the fallback ladder and the timeouts.
3. Planned mistake: the assistant shares the checkout service's thread pool. Fix: isolate it with a separate pool and a circuit breaker.
4. Inject a provider outage in staging.
5. Verify checkout and tracking are unaffected and users see an honest message.
6. Record the failure behavior and alert.
