# io8 System Architect Agent - Customized for This Project

## Project-Specific Instructions

## Architecture Document Update - 2025-09-25 07:15:00

### System Overview Update
The system is a simple calculator application implemented as a single-page application (SPA).  There is no backend component; all logic resides within the frontend.  The architecture focuses on a clear separation of concerns between the user interface (UI), business logic, and data handling.

### Architecture Pattern Update
The application will use a Model-View-ViewModel (MVVM) architectural pattern. This pattern facilitates a clean separation of concerns, making the application more maintainable and testable. The model represents the data, the view is responsible for the user interface, and the view model acts as an intermediary between the model and the view, handling data transformations and user interactions.

### Component Design Update
The application will consist of the following components:

* **CalculatorComponent:** The main component, responsible for rendering the calculator's UI and handling user interactions.
* **DisplayComponent:** A child component of CalculatorComponent, displays the current input and results.
* **ButtonComponent:** A reusable child component, representing a single calculator button (numbers, operators, etc.).

### Data Architecture Update
The application will not use a database.  All data is managed in memory within the CalculatorComponent's view model.  The current input and the calculation results will be stored as properties of the view model.

### API Design Update
No APIs are required for this application.

### Security Architecture Update
No specific security measures are required for this simple calculator application.

### Scalability Considerations Update
This application is not expected to require significant scalability.  As a single-page application with no backend, it scales efficiently within the limits of the browser and hosting environment.

## Technology Stack Update - 2025-09-25 07:15:00

### Frontend Technologies Update
- **Framework:** Angular
- **Styling:** CSS (possibly with a CSS framework like Bootstrap for responsiveness, but not strictly required for this simple application)
- **State Management:**  None (application state is simple enough to be managed within the CalculatorComponent's view model)

### Backend Technologies Update
- N/A (No backend is required for this application)

### Database Technologies Update
- N/A (No database is required for this application)

### Infrastructure Update
- **Deployment:** Static hosting (e.g., GitHub Pages, Netlify, etc. are suitable choices)
- **Hosting:** Any static site hosting provider

### Development Tools Update
- **Version Control:** Git
- **Testing:** Jasmine and Karma (Angular's default testing framework)
- **CI/CD:**  Optional; a simple CI/CD pipeline could be set up using GitHub Actions or similar tools if desired.
