## Overview

TaskFlow is presented as a workflow-management backend, but the sampled runtime implements user registration and a health check; it does not establish workflow-management or login behavior. The registration path accepts a request, delegates user creation to a service, and persists the resulting user through a JPA repository. The health endpoint returns a static status. The README and sampled files provide no further product-flow detail.
