- FastAPI backend with scenario management
- PostgreSQL database schema for scenarios, metrics, logs
- AWS pricing table with real pricing data
- React frontend dashboard (planned)
- PII detection and token counting
- Report generation (PDF/CSV)
- Complete test suite with pytest
- Docker Compose setup
- Documentation: README, PRD, Architecture
- OpenCode configuration (.opencode/)
