mcp.graphsheets.ai · 2026-11-14 01:16:14 UTC · fe4ac1571c65afcb8f927b01b8b149ab8903985f07efe7e33f865f6f18d07cb4
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.
