AI agents do not replace Shopify Flow or OMS state machines. Hybrid is the default: rules own money movement; the agent returns a structured decision. Reuse Gateway ~180 to 95 ms and ~$791/mo at 50K sessions — not store conversion KPIs.

AgentCore Harness went GA June 17, 2026. Use n8n for process orchestration and @aws/n8n-nodes-agentcore to invoke Harness — pin the ARN in production. Reuse the Gateway ~180→95 ms canary; do not treat n8n as the agent runtime.

n8n on EKS: queue mode, RDS Postgres, Redis/Valkey, ALB+WAF, IRSA. July 2026 production checklist.
