The record does not establish execution or any change to Ketju approval.

## Confirmed

- Sixteen stablecoin reserves would receive a 10-basis-point Slope1 increase.
- Five USDe deployments would move the base rate to 6% and reduce Slope1 by one percentage point.

## What it means for an advisor

- Add implementation monitoring to the September 15 Aave memo review and reassess borrowing-cost and stressed-liquidity assumptions before extending market coverage.
