* AICF Cryptographic Format Encoding (CFE) - Proof of Concept
*
* Revolutionary AI-native security approach based on Copilot's research:
* - Symbol-based encoding instead of human-readable format
* - Cryptographic hashing for integrity verification
* - Format obfuscation to prevent reverse engineering
* - AI-readable but human-opaque data structures
*
* SECURITY BENEFITS:
* ✅ Format structure hidden from attackers
* ✅ Content integrity verification built-in
* ✅ Resistant to regex-based attacks
* ✅ Steganographic potential for future expansion
