**Covered Extractors**:
- ZipExtractor
- TarExtractor

**Test Count**: 12 tests

**Key Scenarios**:
- ✅ Descriptive error messages for invalid archives
- ✅ Continues processing when some entries fail
- ✅ Handles empty archives gracefully
- ✅ Mixed valid/invalid entries processed correctly
- ✅ Null input stream validation
