  "description": "Deterministic simulation framework for MeshCore LoRa mesh networking firmware. Enables testing and analysis of mesh network behavior, radio propagation, and protocol performance. Simulates repeaters, companions, and room servers with real-time visualization via Rerun, configurable topologies via YAML, terrain-aware radio propagation using the NTIA Irregular Terrain Model, and full packet export to JSON with decoded MeshCore packet structure.",
