## Overview

CaloriesCounter is a small ASP.NET Core MVC calorie tracker. A user reaches the Home controller through the default route, where food items can be added, edited, deleted, and listed with a summed calorie total; the controller keeps items in a static in-memory list. The controller uses the FoodItem model and returns MVC views. The tree identifies Index and Edit views, but their contents and form wiring were not sampled, so those interactions are not inferred. No persistent database is shown.

Main entry points: [`Controllers/HomeController.cs`](https://github.com/energyz0r/caloriescounter/blob/main/Controllers/HomeController.cs) (Home actions), [`Program.cs`](https://github.com/energyz0r/caloriescounter/blob/main/Program.cs) (MVC startup), [`Models/FoodItems.cs`](https://github.com/energyz0r/caloriescounter/blob/main/Models/FoodItems.cs) (Food item), [`Views/Home/Index.cshtml`](https://github.com/energyz0r/caloriescounter/blob/main/Views/Home/Index.cshtml) (Food list)

## Components

### Web runtime

- [MVC startup](https://github.com/energyz0r/caloriescounter/blob/main/Program.cs): `Program.cs`

### Food tracking

- [Home actions](https://github.com/energyz0r/caloriescounter/blob/main/Controllers/HomeController.cs): `Controllers/HomeController.cs`
- [Food item](https://github.com/energyz0r/caloriescounter/blob/main/Models/FoodItems.cs): `Models/FoodItems.cs`

### User interface

- [Food list](https://github.com/energyz0r/caloriescounter/blob/main/Views/Home/Index.cshtml): `Views/Home/Index.cshtml`
- [Edit form](https://github.com/energyz0r/caloriescounter/blob/main/Views/Home/Edit.cshtml): `Views/Home/Edit.cshtml`

### Other components

- **User**

## Connections

- User → MVC startup: sends requests
- MVC startup → Home actions: routes requests (evidence: `Program.cs`)
- Home actions → Food item: uses model (evidence: `Controllers/HomeController.cs`)
- Home actions → Food list: returns list view (evidence: `Controllers/HomeController.cs`)
- Home actions → Edit form: returns edit view (evidence: `Controllers/HomeController.cs`)
