The etcd client API listens on the masters' static LAN address, and the pod-source deny lists omitted it. Add 2379 to both nft drop lines and assert it in the security-k3s-pod-firewall eval test. 2381 (etcd metrics, scraped by in-cluster monitoring) stays reachable by design. Pairs with the matching Cilium egressDeny port in k8s-gitops. Assisted-by: DeepSeek Harness (gpt-6-astra)
