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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
