Before you relay or act on a claim-backed answer from another agent, check whether every claim is grounded. An A2A-compatible relay-readiness gate for agent-to-agent output hand-off: bring the claim set and its evidence; get a machine-actionable verdict — allow_relay, verify_before_relay, or block_u
