Order Workflow Reliability and Recovery I

Order Workflow Reliability and Recovery

I built local order and shipment workflow prototypes with TypeScript/Node.js, SQLite and n8n. The workflow validates incoming events, suppresses duplicate deliveries, limits retries and checks remote state before replaying an uncertain write.

The recorded local verification on 6 October 2026 contains 15 passing scenarios. They cover repeated deliveries, transient failures, dropped responses, persisted state after restart and failed readback. These checks demonstrate local recovery behaviour using synthetic orders and local APIs; they are not a customer production deployment.

A handover can include the workflow, event schema, failure log, recovery instructions and acceptance scenarios. Connecting an actual business API requires checking its contract and testing in the approved environment.
