shadow-network 0.1.0

//! Phase 4 Demo — Advanced Anonymity & Network Intelligence
//!
//! Demonstrates all five Phase 4 subsystems:
//! 1. Onion Routing — circuit-based multi-hop anonymous routing
//! 2. Traffic Analysis Resistance — constant-rate shaping, mixing, fingerprint detection
//! 3. Pluggable Transports — bridge relays, obfuscation, domain fronting
//! 4. Reputation System — trust scoring, Sybil defense, behavioral analysis
//! 5. Network Simulation — adversary models, censorship, correlation attacks
