Last check, 2026-11-02 02:53 UTC: warn

• warn looks like an A2A 0.3 card (top-level url, preferredTransport, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• warn supportedInterfaces[0].url is on mcp.hakuto-0209.com, not b612-a2a.vercel.app - fine if intended, but a client cannot tell it apart from a card pointing somewhere it should not
• warn supportedInterfaces[1].url is on mcp.hakuto-0209.com, not b612-a2a.vercel.app - fine if intended, but a client cannot tell it apart from a card pointing somewhere it should not
• warn supportedInterfaces[1].protocolVersion is 0.3; current is 1.0
• warn signature 1 (kid 'b612-a2a-2026-09', EdDSA) verifies over the card as served, not over the spec's canonical form, which drops empty fields (8.4.1); the card is unaltered, but a strict verifier will reject it
• info not probing https://mcp.hakuto-0209.com/a2a/v1: it is not on b612-a2a.vercel.app
• info not probing https://mcp.hakuto-0209.com/a2a/v1: it is not on b612-a2a.vercel.app
