This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"description": "External application-level evidence gate for agent workflows. Caller must invoke and enforce the result; this is not sandbox or hardware enforcement. Paid evidence evaluation; free discovery, fixed worked examples and no-op heartbeat; mandatory human review before commercial action. No independent factual verification or clearance. External evidence review for agent-to-agent delivery disputes and proposed escrow allocations. Checks hashes, a bounded offline JSON Schema subset and SLO evidence. Unsupported schemas require human review; no settlement is executed or authorized. New to these gates? Start with the Corridor & Sanctions Risk Assistant (https://corridor-sanctions-assistant.agendamcp.dpdns.org) for plain-language orientation. Describe the route or counterparty and the next decision or review; fit, scope, fee, and timing are confirmed before work starts.",
