# `:core:data`

## Overview
The `:core:data` module holds the concrete implementations of the `:core:repository` contracts, serving as the primary data source for ViewModels in feature modules. It orchestrates data flow between the local database (`core:database`), remote services, and network repositories.

## Key Components

### 1. Repository implementations (`repository/`)
- **`NodeRepositoryImpl`**: High-level access to node information and mesh state (Room KMP backed).
- **`MeshLogRepositoryImpl`**: Access to historical logs and diagnostics.
- **`FirmwareReleaseRepositoryImpl`**: Manages the discovery and retrieval of firmware updates.

### 2. Manager implementations (`manager/`)
- **`SessionManagerImpl`**: Per-node remote-admin passkey store.
- **`PacketHandlerImpl`** / **`MeshMessageProcessorImpl`**: Inbound mesh packet handling and message processing.
