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
Detect whether an arbitrage opportunity exists in a set of token exchange rates (multi-pool negative-cycle scan). Cheap boolean + magnitude signal for trading agents. POST a swap-rate graph, get back whether a profitable cycle exists and how large — without the path.
