# 📊 Executive Summary: Repository Analysis & Remediation Plan
**Senior Rust Staff Engineer Review - September 20, 2025**

## 🎯 Executive Overview

This repository contains a **comprehensive Leptos ShadCN UI component library** with **653 Rust files** across **50+ components**. While the **architectural foundation is solid**, the codebase requires **significant remediation** to achieve production-ready status.

### **Key Findings**

- ⚠️ **Test Coverage Crisis**: ~30% overall coverage with many stub implementations
- ⚠️ **File Size Violations**: Several files exceed 300-line limit
- ⚠️ **API Inconsistencies**: Mixed patterns across components
- ✅ **WASM Support**: Recently added with v0.2.0
- ⚠️ **Rust Version**: Using 1.89.0 (August 2025) - needs update
