🏗️ Architecture Overview

🎯 Core Concept: CLMSR (Continuous Logarithmic Market Scoring Rule)

CLMSR is an automated market maker algorithm for prediction markets:

• Price Formula: P_i = exp(q_i/α) / Σ_j exp(q_j/α)
• Cost Formula: C = α * ln(Σ_after / Σ_before)
• Liquidity Parameter: α (configurable per market)

🛡️ Security Enhancements

🔒 Critical Security Fixes Applied

Issue	Severity	Description	Status
Zero-Cost Attack	🔴 Critical	fromWad() truncation allowing free positions	✅ FIXED
Gas DoS Attack	🔴 Critical	Unlimited chunk splitting causing gas exhaustion	✅ FIXED
Time Validation	🟡 Medium	Trading in expired markets	✅ FIXED
Overflow Protection	🟡 Medium	Mathematical overflow in large trades	✅ FIXED

🛡️ Security Mechanisms

1. Round-Up Cost Calculation

   // Before: fromWad() - truncation allows 0 cost
   uint256 cost6 = costWad.fromWad();
   
   // After: fromWadRoundUp() - guarantees minimum 1 micro USDC
   uint256 cost6 = costWad.fromWadRoundUp();

2. Gas DoS Protection

   uint256 private constant MAX_CHUNKS_PER_TX = 100;
   
   uint256 requiredChunks = (quantity + maxSafeQuantityPerChunk - 1) / maxSafeQuantityPerChunk;
   if (requiredChunks > MAX_CHUNKS_PER_TX) {
       revert InvalidQuantity(uint128(quantity));
   }

3. Time Boundary Validation

   if (block.timestamp < market.startTimestamp) {
       revert InvalidMarketParameters("Market not started");
   }
   if (block.timestamp > market.endTimestamp) {
       market.isActive = false;
       revert InvalidMarketParameters("Market expired");
   }
