Last check, 2026-11-02 02:46 UTC: warn

• warn looks like an A2A 0.3 card (top-level url, preferredTransport, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• info declares https://github.com/google-a2a/a2a-x402/v0.1
• info declares https://a2a-registry.org/extensions/registry/v1
• warn supportedInterfaces[1].protocolVersion is 0.3; current is 1.0
• info signature 1 (kid '854ae25d92ed49e7', EdDSA) is valid; the key is published on the card's own host, so this proves the card is unaltered, not who signed it
• warn endpoint https://borderscout.scalpstream.com/a2a does not implement GetTask, which v1.0 requires
• warn endpoint https://borderscout.scalpstream.com/a2a does not implement GetTask, which v1.0 requires
