* Introduce a new `:feature:discovery` module for scanning mesh topology across multiple LoRa presets * Add `DiscoveryScanEngine` to manage scan lifecycles, preset shifting, and packet collection * Update database schema to version 39 with tables for discovery sessions, preset results, and discovered nodes * Implement UI screens for scan configuration, real-time progress, and historical session management * Add flavor-specific discovery maps (Google Maps and OSM) for visualizing node positions and topology * Include algorithmic and AI-powered summary generation for analyzing LoRa preset performance * Add report export functionality for Text and PDF formats * Integrate discovery entry point into the settings screen and navigation graphs
:app
Overview
The :app module is the entry point for the Meshtastic Android application. It orchestrates the various feature modules, manages global state, and provides the main UI shell.
Key Components
1. MainActivity & Main.kt
The single Activity of the application. It hosts the shared MeshtasticNavDisplay navigation shell and manages the root UI structure (Navigation Bar, Rail, etc.).
2. MeshService
The core background service that manages long-running communication with the mesh radio. While it is declared in the :app manifest for system visibility, its implementation resides in the :core:service module. It runs as a Foreground Service to ensure reliable communication even when the app is in the background.
3. Koin Application
MeshUtilApplication is the Koin entry point, providing the global dependency injection container.
Architecture
The module primarily serves as a "glue" layer, connecting:
core:*modules for shared logic.feature:*modules for specific user-facing screens.
