• Preview borrowing against an EXISTING Trove (core previewBorrow, MK-002): a verdict, the binding constraint, the capacity picture, and the resulting ratios. This is the hook to reach for when a position already exists; useBorrowingPower is for sizing an open.

    Parameters

    • __namedParameters: { amount: undefined | bigint; owner: undefined | `0x${string}` }

    Returns UseQueryResult<BorrowPreview, Error>
