Dead Letter Queues for LLM Jobs: Retry Failures Safely in Python

Retries are not a failure strategy — build a Redis Streams dead letter queue to quarantine repeat failures, replay safely, and protect LLM pipelines. Hands-on walkthrough using redis-py and Python: seed jobs, use xreadgroup/xack, move stuck messages to a DLQ, sanitize replays, and run guarded workers.
