- ✅ Failed extraction includes descriptive error messages
- ✅ Null input stream validation
- ✅ Error messages include file type context

### 2. FilenameExtractorEnhancedTest.java
**Purpose**: Test FilenameExtractor edge cases and new documentation.

**Key Test Areas**:
- Parameter handling (null, empty, missing)
- Special character handling
- Input stream validation (not consumption)
