# checks.rs — Diagnostics Two utility commands for diagnostics and maintenance. **`ping()`** Prints `"PING FROM RUST"` to the console. Used to verify the Tauri bridge is working. **`clear_cache()`** Deletes all contents of the `base_station/` folder inside the system cache directory. Exposed as a callable command so the frontend can trigger a manual cache wipe. `clear_cache_on_startup()` is the internal (non-command) version called automatically every time the app launches.

**Note for future developers:** Clearing the cache on startup is necessary, without doing so the video feed and other assets will not load in some devices.
