Why this order?
Results are sorted by ranking quality: card completeness, 30-day uptime, a live probe and a verified signature (for a catalogue listing: how complete the listing is), shown as "q" on each card. Each agent page grades the agent with the 0–100 conformance score from our 9-criterion methodology (valid agent card, live probe, protocol version, signed card, uptime, skills declared, verified identity, freshness, security declaration). Machine-readable schema: conformance.json. No paid placement, no editorial weights.
