# Know Foolery - Claude Implementation Plan

## Project Overview

**Know Foolery** is a comprehensive quiz game application based on the French game "Déconnaissance". The project implements a cross-platform solution with web, mobile (iOS/Android), and desktop applications, featuring secure authentication, microservices architecture, and comprehensive observability.

## Technology Stack

- **Backend**: Go with Fiber framework, microservices architecture
- **Database**: PostgreSQL (production), SQLite (development)
- **ORM**: Ent for type-safe database operations
- **Cache**: Redis for session management and caching
- **Authentication**: Self-hosted Zitadel (OAuth 2.0/OIDC)
- **Frontend**: React (web), React Native (mobile), Wails (desktop)
- **UI Framework**: Gluestack UI for cross-platform consistency
- **Styling**: NativeWind/Tailwind CSS
- **Monitoring**: Prometheus, Grafana, Jaeger
- **Containerization**: Docker with Docker Compose

- [ ] Conduct production readiness review
- [ ] Implement production security measures

### Phase 10: Launch & Post-Launch
- [ ] Conduct final testing and quality assurance
- [ ] Deploy to production environment
- [ ] Monitor launch metrics and performance
- [ ] Address any post-launch issues
- [ ] Gather user feedback and analytics
- [ ] Plan future feature development

## Key Architectural Decisions

1. **Repository Pattern**: Used only for external API integrations (Zitadel), direct Ent client usage for database operations
2. **Security First**: Critical vulnerabilities addressed in early phases (1-3), enhancements in Phase 8
3. **Cross-Platform UI**: Gluestack UI for consistent design across web, mobile, and desktop
4. **Microservices**: Go with Fiber framework for high-performance, maintainable services
5. **Self-Hosted Auth**: Zitadel for complete control over authentication and user data
6. **Comprehensive Testing**: Unit and integration testing after each implementation phase

## Current Status

**Phase 0 Complete**: All documentation has been created and is ready for implementation. The project has comprehensive documentation covering:

- Complete requirements and specifications
- Technical architecture with microservices design
- Security requirements and implementation strategy
- Cross-platform UI strategy with Gluestack UI
- Development guidelines and coding standards
- Observability and monitoring strategy
- Game mechanics and anti-cheating measures
- Zitadel authentication integration

**Next Steps**: Ready to begin Phase 1 (Project Setup & Core Security Infrastructure) upon approval to proceed with implementation.
