- **`org.codelibs.curl.io.ContentOutputStream`**: Streaming utilities for efficient content handling

### Key Design Patterns

1. **Fluent Builder Pattern**: `CurlRequest` uses method chaining for configuration
2. **Factory Pattern**: `Curl` class provides static factory methods for each HTTP method

        verifyNoMoreInteractions(mockDir);
    }

## 🏗️ Architecture & Design Patterns

### Core Design Principles
CoreLib follows a **utility-class pattern** where most functionality is exposed through static methods:
