Card snapshot

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.

(2) A2A: discover this Agent Card at /.well-known/agent-card.json and invoke the generate_dashboard skill. (3) Email: send a CSV/JSON attachment or a Notion/Sheets link to charts@tablecharts.co.
