- Added comprehensive bounds checking to prevent buffer overruns in multicall parsing - Implemented graduated validation system (Strict/Moderate/Permissive) to reduce false positives - Added LRU caching system for address validation with 10-minute TTL - Enhanced ABI decoder with missing Universal Router and Arbitrum-specific DEX signatures - Fixed duplicate function declarations and import conflicts across multiple files - Added error recovery mechanisms with multiple fallback strategies - Updated tests to handle new validation behavior for suspicious addresses - Fixed parser test expectations for improved validation system - Applied gofmt formatting fixes to ensure code style compliance - Fixed mutex copying issues in monitoring package by introducing MetricsSnapshot - Resolved critical security vulnerabilities in heuristic address extraction - Progress: Updated TODO audit from 10% to 35% complete 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
