## Overview

This appears to be a Spring application for authentication, city management, and weather lookup. The tree identifies API controllers, services, provider abstractions, repositories, and domain entities, but the README is empty and no source excerpts were supplied. The graph therefore maps the identifiable product areas without asserting call paths, storage technology, or external-service wiring that the available evidence cannot confirm.
