Implement Adversarial-Resilient Economic System with Organizational Framework

[Copilot]

This PR implements a comprehensive adversarial-resilient economic system for ICN that maintains cooperative values while hardening the network against malicious actors. The implementation introduces Byzantine fault tolerance, game-theoretic security, and a new organizational framework differentiating between Cooperatives, Communities, and Federations.

Key Features

🏢 Organizational Framework

The system now recognizes three distinct organizational types, each with specialized economic functions:

• Cooperatives: Economic production hubs focused on resource allocation, worker ownership, and inter-cooperative trade
• Communities: Civil and cultural centers managing democratic governance, mutual aid, and care economy
• Federations: Bridging organizations enabling cross-network coordination and collective action

🛡️ Byzantine-Resistant Mana System

The core mana system has been enhanced with adversarial resistance:

// Byzantine consensus for mana regeneration
let consensus_result = ledger.regenerate_mana_byzantine(
    &account_did,
    &verified_capacity_metrics,
    &validator_signatures,
)?;

• 2/3+1 Validator Consensus: All mana operations require Byzantine fault tolerant consensus
• Cryptographic Verification: Capacity proofs are cryptographically signed and verified
• Anti-Gaming Detection: Behavioral analysis detects capacity inflation, reputation farming, and transaction manipulation
• Dynamic Account Status: Accounts can be frozen, penalized, or flagged for review based on suspicious activity

🔒 Game-Theoretic Security

Comprehensive anti-gaming mechanisms protect against exploitation:

• Sybil Attack Detection: Network analysis identifies suspicious identity clusters
• Capacity Inflation Prevention: Detects artificial capacity claims through proof verification
• Transaction Pattern Analysis: Identifies wash trading and manipulation attempts
• Collusion Detection: Analyzes social graphs for coordinated behavior

📊 Enhanced Economics Documentation

Updated the economics model documentation with:

• Detailed Byzantine consensus mechanisms
• Emergency protocol frameworks
• Dynamic pricing under network stress
• Comprehensive adversarial resistance patterns

Technical Implementation

New Modules

• adversarial.rs: Core traits and types for Byzantine fault tolerance and game-theoretic security
• organizational.rs: Detailed organizational type definitions and economic functions
• byzantine_mana.rs: Cryptographically verified mana ledger implementation
• basic_anti_gaming.rs: Game-theoretic security engine with behavioral analysis

Error Handling

Extended CommonError enum with 11 new adversarial error types:

• InsufficientConsensus, GamingDetected, AccountFrozen
• SuspiciousActivity, InvalidProof, InvalidValidator
• And more for comprehensive error coverage

Testing

Added comprehensive test suite with 8 new adversarial security tests covering:

• Byzantine mana ledger functionality
• Anti-gaming behavioral analysis
• Sybil attack detection
• Organizational type management
• Cryptographic proof verification

Backward Compatibility

All changes are additive and maintain full backward compatibility with existing economic operations. The enhanced features are opt-in through the new Byzantine-resistant interfaces while existing functionality continues to work unchanged.

Example Usage

// Create Byzantine-resistant mana ledger
let ledger = ByzantineManaLedger::new(
    validator_set,
    Box::new(BasicAntiGamingEngine::new()),
    Box::new(SystemTimeProvider),
);

// Get balance with risk assessment
let (balance, risk_score) = ledger.get_balance_with_risk_assessment(&account_did)?;

// Secure mana spending with context
let remaining = ledger.spend_mana_secure(&account_did, amount, &spending_context)?;

This implementation provides the foundation for a truly adversarial-resilient cooperative economy that can maintain its values and functions even under coordinated attack.
