linkproof.zopip.com · 2026-11-15 03:57:16 UTC · e352d102b2146c40b5ecc534dd90865cf3cbb57e963d0982fd3c4e98f68a095b

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.
