Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
What it costs to hold a perpetual position: the venue's current hourly funding signed for your side, projected over your horizon in your own units, with the mark-to-oracle basis, open interest, and the assumption behind the projection stated rather than implied.
