Tc9d1d9# `:core:data`

Tc9d1d9## Overview

The Ta5d6ff`:core:data` module holds the concrete implementations of the Ta5d6ff`:core:repository` contracts, serving as the primary data source for ViewModels in feature modules. It orchestrates data flow between the local database (Ta5d6ff`core:database`), remote services, and network repositories.

Tc9d1d9## Key Components

Tc9d1d9### 1. Repository implementations (`repository/`)

Tff7b72- **`NodeRepositoryImpl`**: High-level access to node information and mesh state (Room KMP backed).

Tff7b72- **`MeshLogRepositoryImpl`**: Access to historical logs and diagnostics.

Tff7b72- **`FirmwareReleaseRepositoryImpl`**: Manages the discovery and retrieval of firmware updates.

Tc9d1d9### 2. Manager implementations (`manager/`)

Tff7b72- **`SessionManagerImpl`**: Per-node remote-admin passkey store.

Tff7b72- **`PacketHandlerImpl`** / **`MeshMessageProcessorImpl`**: Inbound mesh packet handling and message processing.
