## Project Overview
The project is an **Angular Clarity Boilerplate**, designed to serve as a foundational template for building modern, scalable, and feature-rich web applications. It provides a pre-configured Angular project integrated with the VMware Clarity Design System, enabling developers to kickstart new projects with a robust and consistent architecture, thereby accelerating the development lifecycle.

## Business Analysis
The primary business need is to **streamline the initial setup phase of new Angular projects** within an organization or for individual developers. The target audience is **Angular developers and development teams** who require a standardized, best-practice project structure. The value proposition is centered around increasing development efficiency, enforcing UI/UX consistency through the Clarity Design System, and reducing the boilerplate code that developers need to write for every new project.

## User Requirements (Developer Requirements)
The "users" of this boilerplate are developers. Their core requirements are:
- Developers must be able to **quickly set up a new project** by cloning the repository and installing dependencies.
- Developers must be provided with a **clear and understandable project structure** that promotes scalability and maintainability.
- The boilerplate must include a **pre-built, responsive application layout** (e.g., header, sidebar, content area).
- Developers must have access to **pre-configured core and shared modules** for common functionalities like services, guards, and reusable components.
- The boilerplate must be **easily extendable** with new feature modules and components.

## Functional Requirements
The boilerplate will provide the following functional capabilities out-of-the-box:

- **Pre-configured Angular Environment:** A ready-to-use Angular CLI project with all necessary dependencies and build configurations.
- **Clarity Design System Integration:** Full integration of Clarity UI components and styles, ready for immediate use.
- **Scalable Architecture:** A modular structure featuring a `CoreModule` for singleton services and a `SharedModule` for reusable UI components, directives, and pipes.
- **Responsive Layout:** A default application shell with a responsive header, navigation sidebar, and main content area.
- **Routing:** A pre-configured routing module with examples of lazy-loaded feature modules.
- **Theming:** Basic support for Clarity's light and dark themes.

## Non-Functional Requirements

- **Performance:** The initial boilerplate should be lightweight, ensuring fast development server startup times and optimized production builds.
- **Usability (Developer Experience):** The codebase must be clean, well-commented, and logically organized to provide an excellent developer experience.
- **Maintainability:** The modular architecture must facilitate easy updates to dependencies and allow for the addition of new features without introducing breaking changes to the core structure.
- **Scalability:** The architecture is designed to support the growth of large, enterprise-scale applications.
- **Extensibility:** The boilerplate should be easy to customize and extend with additional libraries, modules, and configurations as per project-specific needs.

## User Stories (Developer Stories)

### User Story 1: Quick Project Initialization
- **As a developer, I want to clone the repository and run `npm install` and `ng serve` to get a live development server running, so that I can bypass manual setup and start building features immediately.**
- **Acceptance Criteria:**
    - Given I have Node.js and Angular CLI installed,
    - When I clone the repository, install dependencies, and run the start command,
    - Then the application compiles successfully and is accessible in my browser at `localhost:4200`.

### User Story 2: Add a New Feature
- **As a developer, I want to create a new lazy-loaded feature module with its own components and routing, so that I can add new sections to the application in a scalable way.**
- **Acceptance Criteria:**
    - Given the boilerplate is running,
    - When I use the Angular CLI to generate a new module and add it to the main routing configuration,
    - Then I can navigate to the new feature's route, and its components are rendered correctly.

### User Story 3: Utilize Shared Components
- **As a developer, I want to use a component from the `SharedModule` within a new feature module, so that I can reuse common UI elements and maintain consistency.**
- **Acceptance Criteria:**
    - Given I have a new feature module,
    - When I import the `SharedModule` into my feature module,
    - Then I can use the shared components (e.g., a custom card or loader) in my feature's templates without errors.

## Business Rules (Architectural Principles)
- Singleton services (e.g., logging, authentication) must be provided in the `CoreModule`.
- Reusable components, pipes, and directives that do not have a dependency on services must be declared and exported in the `SharedModule`.
- All major application features should be encapsulated within their own lazy-loaded modules.
- Environment-specific variables (e.g., API endpoints) must be managed in the `environments` folder.

## Analysis Document Update - 2025-09-25 07:00:00

This section updates the analysis document based on the user prompt and the revised project breakdown.

### Project Overview Update
The project goal is to develop a simple calculator application.  Based on the `io8codermaster` breakdown, a backend is not required for this project.

### User Requirements Update
The user requires a functional calculator application that performs basic arithmetic operations (+, -, *, /).  Error handling, such as division by zero, is a critical requirement.

### Functional Requirements Update
The following functional requirements have been identified:

* **FR-001: Perform Addition:** The calculator shall correctly add two numbers.
* **FR-002: Perform Subtraction:** The calculator shall correctly subtract two numbers.
* **FR-003: Perform Multiplication:** The calculator shall correctly multiply two numbers.
* **FR-004: Perform Division:** The calculator shall correctly divide two numbers.  It shall handle division by zero gracefully, displaying an appropriate error message.
* **FR-005: Handle User Input:** The calculator shall accept numerical input from the user via buttons.
* **FR-006: Display Results:** The calculator shall display the results of calculations clearly to the user.

### Non-Functional Requirements Update

* **NFR-001: Usability:** The calculator shall be intuitive and easy to use.
* **NFR-002: Responsiveness:** The calculator shall be responsive and work seamlessly across various devices and browsers.
* **NFR-003: Performance:** The calculator shall provide quick calculation results with minimal latency.

### User Stories Update

* **US-001:** As a user, I want to be able to add two numbers together so that I can perform basic arithmetic.
* **US-002:** As a user, I want to be able to subtract two numbers so that I can perform basic arithmetic.
* **US-003:** As a user, I want to be able to multiply two numbers so that I can perform basic arithmetic.
* **US-004:** As a user, I want to be able to divide two numbers so that I can perform basic arithmetic.  I expect an appropriate error message if I try to divide by zero.
* **US-005:** As a user, I want a clear display showing the result of my calculations.
