## Overview

Trade Task Manager is a browser-based task CRUD application backed by Spring Boot and PostgreSQL. Users manage tasks through the web UI; the REST controller handles listing, creation, updates, deletion, title search, and status statistics, delegating persistence queries to the repository. The task entity defines the persisted record. The README documents the browser-to-API and repository-to-database architecture; source excerpts confirm controller/repository/model responsibilities. The UI implementation and runtime configuration were not sampled, so their internal behavior is not inferred.
