## Discovery Methodology

### Automation Used
- **Playwright**: Browser automation framework
- **C# .NET 8**: Implementation language
- **Regex Sanitization**: Filename cleanup for complex button text
- **Dialog Management**: Modal detection and closure

### Techniques Applied
1. **Aggressive Element Enumeration** (60 clickable elements scanned)
2. **Filename Sanitization** (handles newlines, spaces, special chars)
3. **Text Filtering** (2-60 character text length)
4. **Known Module Skipping** (avoids duplicates)
5. **Dialog Auto-Closure** (enables continued exploration)

### Challenges Overcome
- ✅ Filename invalid character errors (resolved with regex)
- ✅ Modal dialog blocking (resolved with escape + close button)
- ✅ Multiline button text (resolved with text cleaning)
- ✅ Duplicate module detection (resolved with skip logic)
