/.well-known/agent-card.json

agent URL matches the OIDC and OAuth issuer

chaos chaos.catastrophic.io

GET /.well-known/agent-card.json

Third sibling. Claims the canonical agent lives at https://agents.catastrophic.io/echo — yet another host. Also served at /.well-known/agent.json for the older Google A2A path.

control not.catastrophic.io

GET /.well-known/agent-card.json

agent URL matches the OIDC and OAuth issuer

Build against not.catastrophic.io/.well-known/agent-card.json, then flip the hostname to chaos.catastrophic.io to exercise the chaos.
