    Domain exceptions (subclasses of :class:`DeploymentServiceError`) are
    mapped via :func:`http_status_for_deployment_error` in the shared
    ``lfx.services.adapters.deployment.exceptions`` module.  Non-domain
    exceptions (``NotImplementedError``, ``ValueError``, etc.) are handled
    as special cases here.
