- Security: 0 vulnerabilities (cargo audit clean)
- Code Volume: ~34,000 LOC across 7 active crates
- Fuzzing: 5 libFuzzer targets (frame_parser, dht_message, padding, crypto, tree_hash)
- Property Tests: 29 proptest invariants for state machine validation
- Unsafe Code: 50 blocks, 100% documented with SAFETY comments
- Documentation: 60+ comprehensive files

Implementation Status:
- Updated test breakdown by crate with accurate counts
- wraith-core: 206 tests
- wraith-crypto: 123 tests
- wraith-files: 39 tests
- wraith-obfuscation: 167 tests
- wraith-transport: 203 tests
- wraith-discovery: 88 tests
