Manages the connection to Meshtastic's IMeshService via Android service binding. Implements a thread-safe singleton pattern with connection lifecycle management, reconnection logic, and callback handling. Demonstrates clean separation of concerns for service interaction that could be reused in other Android service integration scenarios.

Implements Luby Transform (LT) fountain codes for reliable data transfer over lossy mesh networks. Handles packet encoding, decoding, and reassembly with timeout management and duplicate detection. The implementation is self-contained and could be extracted for use in any unreliable transport scenario requiring robust bulk data transfer.

A Kotlin wrapper around Android's SharedPreferences that safely handles type conversions and prevents ClassCastException/NumberFormatException crashes. Provides type-safe getters with default values and null safety. This utility pattern is broadly applicable to any Android preference management scenario.

Provides AES-256-GCM encryption and decryption functionality with proper IV handling and base64 encoding. Includes key generation from pre-shared keys. The implementation follows cryptographic best practices and could be reused in any application requiring symmetric encryption with authentication.
