Harness Details

The content fuzz harness is properly structured:

• Uses libfuzzer_sys::fuzz_target! macro
• Tests the content stream interpreter (process_with_mode)
• Validates INV-8 (no panic at public boundary)
• Tests both ProcessingMode::Normal and ProcessingMode::PositionHint
• Uses minimal empty ResourceDict for testing

Conclusion

All acceptance criteria PASS. The content fuzz harness exists and is correctly implemented.
