Production-Ready n8n: error handling, graceful retries and security

I've seen too many comments on how production automation workflows fail silently or bring down entire systems when a single API call times out. Just published a guide covering the error handling, retry logic, and security patterns that prevent this:

Some problems: - Single unhandled error cascades through your entire workflow - No visibility into what failed or why - No automatic recovery from transient failures - Webhooks are wide-open security holes

General Solutions: - Centralized error workflows that capture full failure context - Exponential backoff retry logic - Try/Catch blocks for risky operations - Webhook authentication with HMAC validation

Also included: An interactive retry logic simulator, webhook security tester, and a complete production deployment checklist.

Would love feedback from HN on what else should be covered for production n8n deployments.
