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.

"name": "M2M Escrow Arbiter \u2014 Delivery Evidence Review",
"description": "Compare escrow delivery evidence with agreed hashes, supported schemas, deadlines and SLO records for dispute review. 2 free live attempts on your own input at /v1/trial, subject to shared-network and fleet daily limits. Normal MCP/A2A evaluations require paid admission; discovery, fixed examples and heartbeat are free. Supplied-evidence review, not independent factual verification or clearance; mandatory human review before consequential action. Caller must invoke and enforce the result in its integration. 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.",
