+- D601 的 HWLAB DEV 运行态只允许使用自部署原生 k3s；Docker Desktop Kubernetes 已经停用并清理数据，任何人不得重新启用或把它作为 HWLAB DEV、MVP、CI/CD、smoke、部署或验收目标。跨仓库事故跟踪见 [pikasTech/unidesk#138](https://github.com/pikasTech/unidesk/issues/138)，指挥官热修复背景见 [pikasTech/unidesk#118](https://github.com/pikasTech/unidesk/issues/118)。
+- D601 上裸 `kubectl` 不可信：默认 kubeconfig 可能仍残留 `docker-desktop` / `127.0.0.1:11700`。所有 D601 `hwlab-dev` 只读观测、DEV CD、rollback、smoke 和排障必须显式使用 `KUBECONFIG=/etc/rancher/k3s/k3s.yaml`，并确认节点名是 `d601`。
+- 发现 `docker-desktop` context、`desktop-control-plane` 节点、Docker Desktop Kubernetes 中的 `hwlab-dev` 残留，或同一 HWLAB 资源被第二控制面承载时，必须停止部署/验收并按 #138 处理；不要把第二控制面或失效默认 kubeconfig 的输出作为 DEV-LIVE 证据。
+
+## P0 GitHub Issue 写入纪律
+
+- HWLAB #7、用户反馈、长期看板和指挥简报的 GitHub issue 正文写入必须走 UniDesk CLI：`cd /root/unidesk && bun scripts/cli.ts gh ...`；禁止直接用原生 `gh issue edit/create/comment` 写这些 issue。事故和工具补强需求见 [pikasTech/unidesk#142](https://github.com/pikasTech/unidesk/issues/142)。
+- 在 UniDesk CLI 局部替换、写前备份和写后 hash 验证能力完成前，不要对 #7 做无 guard 的整篇 body replace；必须先保留 before body、确认维护纪律 heading 仍存在，再写入。
+
 ## 工作区
 
 - Runner 和指挥常用工作区是 `/workspace/hwlab`；进入仓库先检查分支与工作树状态，详见 [docs/reference/commander-collaboration.md](docs/reference/commander-collaboration.md)。

+## D601 Native k3s Emergency Guard
+
+HWLAB DEV deploy and publish paths must target D601 native k3s only. Docker
+Desktop Kubernetes on D601 has been disabled and cleaned; it must not be
+re-enabled or used as a second orchestrator. The cross-repo incident, evidence,
+and governance plan are tracked in
+[pikasTech/unidesk#138](https://github.com/pikasTech/unidesk/issues/138), and
+the 2026-05-23 commander recovery context is in
+[pikasTech/unidesk#118](https://github.com/pikasTech/unidesk/issues/118).
+
+Every DEV CD status, apply, rollback, smoke, and manual Kubernetes command must
+use `KUBECONFIG=/etc/rancher/k3s/k3s.yaml` and verify node `d601` before any
+mutation or acceptance. Bare `kubectl`, `docker-desktop` context,
+`desktop-control-plane`, or `127.0.0.1:11700` are wrong-control-plane signals,
+not HWLAB DEV-LIVE evidence.
