act_runner moved from koala's bare host network into a k3s pod (2026-07-26); loopback inside that pod's own network namespace never reaches the host, so the git.d-ma.be SSH override (used to push the infra repo update) failed with "Connection refused". Verified TCP+SSH-handshake reachability to gitea-ssh-nodeport.gitea.svc.cluster.local:22 from inside the actual runner pod before committing this.
