- Add staking/unstaking actions to fuzzing scenarios (stake every 3rd trade)
- Implement snatching logic when stake pool reaches capacity (uses max tax rate)
- Add configurable parameters:
- buyBias: Control buy vs sell ratio (0-100%)
- stakingBias: Control stake vs unstake ratio (0-100%)
- tradesPerRun: Configure number of trades per scenario
- staking: Enable/disable staking entirely
- Simplify to single trading strategy (_executeRandomLargeTrades)
- Fix memory issues by recording only every 5th trade to CSV
- Track staking metrics (stakes attempted/succeeded, snatches attempted/succeeded)
- Update CLAUDE.md with new fuzzing parameters and usage examples
- Clean up old TODO files and unused code

- Deploy Uniswap factory once before all runs (saves ~1.16M gas per run)
- Fix CSV buffer accumulation bug by clearing buffer between runs
- Add clearCSV() function to CSVManager for proper buffer management
- Each fuzzing run now gets its own clean CSV with correct token0isWeth values
- Comment out failing console.log in Optimizer.t.sol to fix compilation
The token ordering now correctly alternates:
- Even seeds: token0isWeth = true (WETH < KRAIKEN)
- Odd seeds: token0isWeth = false (KRAIKEN < WETH)

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.
