The swarm inventory carried the manager's docker bridge gateway as a literal under networks.internet.dns, so one field meant two things at once and the value went stale the moment default-address-pools moved the bridge. The daemon kept handing out the new address while the inventory kept naming the old one, and the DinD diagnostic probed that same literal, so it failed in step with the defect instead of catching it. The inventory now declares only the clearnet resolver. The lookup hands containers the bridge whenever the host resolves solely through a loopback listener, which is how the simulated cluster nodes are wired and which docker strips from a container's resolv.conf. The diagnostic reads the gateway from the running daemon instead of being told it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
