Why this order?
Results are sorted by conformance × liveness × verification: a 0–100 score from our 9-criterion methodology (signed card, live probe, protocol version, skills declared, provider attribution, freshness, business identity, uptime) multiplied by a small boost for currently-live + domain-verified agents. Machine-readable schema: conformance.json. No paid placement, no editorial weights.
