KISS, Keep It Simple Stupid +- We do not want to create code that is more complicated than necessary +- When changing code, always make sure to update any relevant tests +- Use proper error handling - aviation applications need reliability + +## SkyView-Specific Guidelines + +### Architecture & Design +- Multi-source ADS-B data fusion is the core feature - prioritize signal strength-based conflict resolution +- Embedded resources (SQLite ICAO database, static assets) over external dependencies +- Low-latency performance is critical - optimize for fast WebSocket updates +- Support concurrent aircraft tracking (100+ aircraft should work smoothly) + +### Code Organization +- Keep Go packages focused: beast parsing, modes decoding, merger, server, clients +- Frontend should be modular: separate managers for aircraft, map, UI, websockets +- Database operations should be fast (use indexes, avoid N+1 queries) + +### Performance Considerations +- Beast binary parsing must handle high message rates (1000+ msg/sec per source) +- WebSocket broadcasting should not block on slow clients +- Memory usage should be bounded (configurable history limits) +- CPU usage should remain low during normal operation + +### Documentation Maintenance +- Always update docs/ARCHITECTURE.md when changing system design +- README.md should stay current with features and usage +- External resources (ICAO docs, ADS-B standards) should be linked in documentation +- Country database updates should be straightforward (replace SQLite file) \ No newline at end of file diff --git
