Event-to-Spreadsheet Automation with Explicit Failure Handling

An AI-assisted Node.js demonstration of reliable event processing: validate inputs and structured responses, limit retries, coalesce concurrent duplicates, and stop when a write outcome is uncertain.

Thirteen offline scenarios passed, including three duplicate requests producing one simulated call and one stored row. The package includes runnable source, scenario results and an explanatory report.

Both external services are simulated; live API authentication, durable storage and deployment are outside this demonstration. Original personal work, not a client integration.
