## Overview

This is a desktop-oriented legal practice assistant: lawyers manage cases and files, use AI-assisted analysis and chat, and produce or review legal documents. The tree shows additional practice-management areas including clients, tasks, templates, statutes, and judge contacts. The README is empty, and most runtime source was not sampled, so the graph emphasizes documented module boundaries and avoids claiming detailed internal call sequences.

Main entry points: [`.lawyer/lib/api.js`](https://github.com/yubuhui/lawyer-assistant-opensource/blob/main/.lawyer/lib/api.js) (Browser API Client), [`.lawyer/lib/case-detail-core.js`](https://github.com/yubuhui/lawyer-assistant-opensource/blob/main/.lawyer/lib/case-detail-core.js) (Case Management), [`.lawyer/routes`](https://github.com/yubuhui/lawyer-assistant-opensource/tree/main/.lawyer/routes) (API Routes), [`.lawyer/lib/home-page.js`](https://github.com/yubuhui/lawyer-assistant-opensource/blob/main/.lawyer/lib/home-page.js) (Home and Navigation)
