IosStorageUsageFileSystem

internal class IosStorageUsageFileSystem(val fileManager: NSFileManager = NSFileManager.defaultManager, val homePath: String = NSHomeDirectory())(source)

Measures and mutates app-private iOS storage used by Settings usage screens.

The paths intentionally match the iOS data layer: downloaded local models live under Library/Application Support/model, while transient app files live under Library/Caches.
