What we could not test
what the tools do when called with real credentials

Connect it under the guard; read the third-party hosts first. The code names lemonsqueezy.com, polar.sh, mcp-schnittstellen.de, aiim.org, purl.org as well as its own vendor. The guard pins the network to the hosts the honeypot saw.
