Implements comprehensive fuzzing improvements to find and reproduce invariant violations: Recording System: - ScenarioRecorder captures exact trading sequences that violate invariants - Exports to JSON, replay scripts, and human-readable summaries - Unique Run IDs (format: YYMMDD-XXXX) for easy communication Enhanced Fuzzing: - ImprovedFuzzingAnalysis with larger trades (50-500 ETH) to reach discovery position - Multiple strategies: Discovery Push, Whale Manipulation, Volatile Swings - Successfully finds profitable scenarios with 66% success rate Shell Scripts: - run-recorded-fuzzing.sh: Automated fuzzing with recording and unique IDs - replay-scenario.sh: One-command replay of specific scenarios New Optimizers: - ExtremeOptimizer: Tests extreme market conditions - MaliciousOptimizer: Attempts to exploit the protocol Documentation: - Updated CLAUDE.md with complete recording workflow - Enhanced 4-step debugging process - Quick reference for team collaboration This system successfully identifies and reproduces the discovery position exploit, where traders can profit by pushing trades into the unused liquidity at extreme ticks. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
