changefeed.dev · 2026-11-06 18:59:31 UTC · 6f3abdc4c3e14210bff302efd75765ae618e8a227b743f0f2e00898ed7712864

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.
