Initial commit: 5 Why Root Cause Analyzer v1.0.0
Phase 0 & Phase 2 completed: - Project structure setup - Environment configuration (.env, .gitignore) - Enterprise-grade dependencies (bcrypt, helmet, mysql2, etc.) - Complete database schema with 8 tables + 2 views - Database initialization scripts - Comprehensive documentation Database Tables: - users (user management with 3-tier permissions) - analyses (analysis records) - analysis_perspectives (multi-angle analysis) - analysis_whys (detailed 5 Why records) - llm_configs (LLM API configurations) - system_settings (system parameters) - audit_logs (security audit trail) - sessions (session management) Tech Stack: - Backend: Node.js + Express - Frontend: React 18 + Vite + Tailwind CSS - Database: MySQL 9.4.0 - AI: Ollama API (qwen2.5:3b) Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
