3. Key Findings

Ultra-TDeck (Legacy/Pro Branch)

Filesystem: Heavily reliant on SPIFFS for data persistence.
Assets: Contains unique PNG logos and high-quality FLAC/MP3 audio snippets for UI feedback.
Focus: Optimized for standalone efficiency with a stable, proprietary protocol.

MeshOS (Modern/Community Branch)

Filesystem: Transitioned to LittleFS for improved flash wear-leveling and reliability.
Protocol: Implements the latest MeshCore hybrid routing (Flood + Path Hash).
Security: Explicit references to AES-256-GCM and ECDH key exchange.
Localization: Includes a significant database of UK place names (Amersham, Aylesbury, etc.), suggesting a built-in regional directory or default node naming scheme.
Connectivity: Enhanced Bluetooth support for external physical keyboards (BT keyboard 2).
