Last check, 2026-11-01 03:05 UTC: fail

• warn looks like an A2A 0.3 card (top-level url, preferredTransport, additionalInterfaces, protocolVersion); v1.0 lists endpoints in 'supportedInterfaces'
• warn supportedInterfaces[0].protocolVersion is 0.3.0; current is 1.0
• fail supportedInterfaces[1].protocolBinding is 'MCP'; expected one of GRPC, HTTP+JSON, JSONRPC
• warn supportedInterfaces[1].protocolVersion is 2025-06-18; current is 1.0
• warn v1.0 JSON uses camelCase; these keys are snake_case: x-angels.terms.terms_url, x-angels.terms.refund_policy, x-angels.terms.sla.availability_target, x-angels.terms.sla.public_health, x-angels.terms.sla.typical_latency_s, x-angels.mcp_server_card
• warn signature 1 (kid 'aether-card-2026-10', 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
• warn endpoint https://angelscohq.com/aether/a2a does not implement GetTask, which v1.0 requires
