### Summary

This proposal updates the Interest Rate Model (IRM) of the anDOLA market on Frontier from the current utilization-based JumpRateModel to a constant rate model.

### Rationale

Frontier is a deprecated product, and leaving excess DOLAs supplied to its markets exposes the protocol to unnecessary risk. A utilization-based model can attract additional liquidity and create fluctuating borrow incentives that no longer serve Frontier’s purpose. Moving to a constant borrow rate makes the market simpler, predictable and better aligned with a wind-down posture, while reducing governance and monitoring overhead.

### Specification

A ConstantIRM contract will be set to anDOLA that returns a fixed borrow rate per block. The suggested rate is ~2.5% APR (matching the current effective borrow rate of the existing model), but governance may set a different constant depending on risk preference.
