Improve Liquidity Buffer for USDC on Aave v3 Ethereum Core

A proposal argues that USDC on Aave v3 Ethereum Core needs a parameter recalibration, because the pool has been essentially pinned at 99.87% utilization for four days, with the variable borrow rate flat near its 14% ceiling. It suggests raising Slope 2 from about 10% to 50% and lowering optimal utilization from 92% to 85%, with an interim Risk Steward step to 40% and 87%. Pool supply fell about $60M in 24 hours as repayments were matched by queued withdrawals. The proposal asks LlamaRisk and Aave Labs to execute the interim change, followed by full-governance ratification within 5–7 days.
