DEUSPROOF A2A Agent

Agent2Agent surface: a signed (JWS EdDSA, kid = the register's did:key) A2A 1.0 agent card at https://deusproof.com/.well-known/agent-card.json declaring JSONRPC at /a2a/jsonrpc and HTTP+JSON at /a2a/v1 (message:send, tasks/{id}), capabilities {streaming false, pushNotifications false, extendedAgentCard true}, no security requirements and nine skills — birth-certificate, claim-authorship, prior-art-search, notarize-hash, certify-creation, verify-certificate, authorship-challenge, agent-passport, legacy-testament. A second, 0.3-compatible card is served at the legacy /.well-known/agent.json. Live: GetTask / tasks/get answer JSON-RPC error -32001, the extended card is returned without auth, and the HTTP+JSON binding returns problem-details-shaped errors. Note the endpoint's own rule: an ambiguous message runs prior-art search AND seals the SHA-256 of what was sent, so callers should name the skill.
