## Overview

RogueMaster is custom Flipper Zero firmware: it combines device services with built-in and community applications. A representative user-to-result path is selecting an application and using its interface to perform a device task; the tree shows broad application domains, while the excerpts chiefly establish storage behavior. The graph therefore preserves the documented application breadth and the supported storage/API relationships without inferring calls between unsampled subsystems. Several application relationships are necessarily omitted because their wiring was not shown.

Main entry points: [`applications/services/storage/storage_external_api.c`](https://github.com/roguemaster/flipperzero-firmware-wplugins/blob/420/applications/services/storage/storage_external_api.c) (Storage API), [`applications/settings/storage_settings/storage_settings.c`](https://github.com/roguemaster/flipperzero-firmware-wplugins/blob/420/applications/settings/storage_settings/storage_settings.c) (Storage settings), [`targets/f7/src/main.c`](https://github.com/roguemaster/flipperzero-firmware-wplugins/blob/420/targets/f7/src/main.c) (Flipper firmware), [`applications/services/storage/storages/storage_ext.c`](https://github.com/roguemaster/flipperzero-firmware-wplugins/blob/420/applications/services/storage/storages/storage_ext.c) (SD backend)
