  "summary": "At-least-once delivery improves the eventual processing of a renewal reminder but requires a durable consumer-side deduplication key to prevent sending the same customer notice twice. The practical design involves accepting at-least-once delivery while making the consumer idempotent with a unique business key. This boundary between queue reliability and consumer-side deduplication is crucial for ensuring reliable customer behavior without unnecessary side effects. The testing of this boundary is essential, and tools like Infrai can be used to verify the queue contract before integration.",
