+# Model
+
+### Purpose
+This module provides the `MenuCommand` class, a simple `ICommand` implementation designed to handle hamburger menu item execution. It serves as a bridge between WPF's command binding system and the application's menu handling logic by invoking a delegate when a menu item is pressed, passing along the menu item's identifier.
+
+### Public Interface
+
+**`MenuCommand` class** - Implements `System.Windows.Input.ICommand`
+
+- **`MenuCommand(string id, MenuItemPressedDelegate menuItemPressed)`** - Constructor. Takes a unique identifier for the menu item and a delegate to invoke upon execution.
+- **`bool CanExecute(object parameter)`** - Always returns `true`. The command is always executable.
+- **`void Execute(object parameter)`** - Invokes the `MenuItemPressed` delegate with the stored `Id`.
+- **`event EventHandler CanExecuteChanged`** - Standard `ICommand` event. Never raised in this implementation.
+
+### Invariants
+- `CanExecute` will always return `true` regardless of the parameter value.
+- `Id` and `MenuItemPressed` are set at construction and cannot be changed (readonly).
+- `MenuItemPressed` delegate must be provided at construction time (no null check visible in source).
+
+### Dependencies
+- **Depends on**: `DTS.Common.Interface.Menu.HamburgerMenu` (for `MenuItemPressedDelegate`)
+- **Depends on**: `System.Windows.Input` (for `ICommand` interface)
+
+### Gotchas
+- The `CanExecuteChanged` event is declared but never invoked, meaning subscribers will never be notified of state changes. This is acceptable given `CanExecute` always returns `true`.
+- No null validation on constructor parameters. Passing a null `menuItemPressed` delegate will cause a runtime exception when `Execute` is called.
