📊 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

• ✅ Strong Foundation: Well-structured workspace with 50+ components
• ⚠️ 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
