- 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)

Replace hardcoded anchorWidth=100 with dynamic calculation that uses staking data as a decentralized oracle.
Changes:
- Add _calculateAnchorWidth() function to Optimizer.sol
- Base width 40% with adjustments based on staking percentage and average tax rate
- Staking adjustment: -20% to +20% (inverse relationship)
- Tax rate adjustment: -10% to +30% (direct relationship)
- Final range clamped to 10-80% for safety
Rationale:
- High staking % = bullish sentiment → narrower anchor (20-35%) for fee optimization
- Low staking % = bearish/uncertain → wider anchor (60-80%) for defensive positioning
- High tax rates = volatility expected → wider anchor to reduce rebalancing
- Low tax rates = stability expected → narrower anchor for fee collection
The Harberger tax mechanism acts as a prediction market where stakers' self-assessed valuations reveal market expectations.
Tests:
- Add comprehensive unit tests in test/Optimizer.t.sol
- Add mock contracts for testing (MockStake.sol, MockKraiken.sol)
- Manual verification confirms all scenarios calculate correctly
Documentation:
- Add detailed analysis of anchorWidth price ranges
- Add staking-based strategy recommendations
- Add verification of calculation logic

The fuzzing script was failing with out-of-gas errors when large KRAIKEN sells
tried to traverse many tick ranges in Uniswap V3. Fixed by adding the
--disable-block-gas-limit flag to forge script execution.
Also fixed the CSV symlink path for the visualizer to work correctly.

- Increased gas limit to 100M to prevent out-of-gas errors during large swaps
- Fixed symlink path for profitable_scenario.csv to work with visualizer
- Position CSVs are now always generated when recording profitable scenarios
The out-of-gas error was occurring when large KRAIKEN sells tried to traverse
many tick ranges in Uniswap V3. The visualizer couldn't display data because
the CSV symlink was created in the wrong directory.

- Replaced old FuzzingAnalysis.s.sol with improved RecordedFuzzingAnalysis
- Old fuzzing used trades too small (0.1-100% of remaining balance) to reach discovery
- New system uses larger trades (50-200 ETH) that successfully find invariants
- run-fuzzing.sh now redirects to run-recorded-fuzzing.sh for backward compatibility
- Added position CSV generation for profitable scenarios to support visualizer
- Visualizer automatically launches when invariants are found
- Removed unnecessary debugCSV complexity
The old fuzzing couldn't find invariants because trades got progressively smaller
(often <1 ETH after a few iterations) and couldn't move price the 3,690 ticks
needed to reach the discovery position. The new system maintains large trade sizes
throughout the scenario, successfully finding profitable exploits.

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.

Converted the debugging reflection into 4 concrete improvement areas:
1. Document Uniswap V3 mechanics & token flows
2. Document optimizer parameters & effects
3. Implement calculation tracing & visualization tools
4. Improve code quality with type safety, tests & invariants
Each TODO has specific tasks and acceptance criteria for implementation.
