 - `artifact-registry plan|render|status|health|install|deploy-backend-core|deploy-service` 管理 D601 host-managed CNCF Distribution registry 的声明、安装、只读检查和 pull-only artifact CD。该 registry 固定为 D601 loopback `127.0.0.1:5000`，由 systemd + Docker Compose 管理，位于 native k3s 故障域外；`deploy-service` 只拉取 CI 已发布的 commit-pinned 镜像、retag/recreate 或导入 native k3s，并做 live commit 验证，不构建 runtime source。`deploy-backend-core` 是 deprecated 兼容名，标准 backend-core prod CD 入口是 `deploy apply --env prod --service backend-core`。长期规则见 `docs/reference/artifact-registry.md`。
 - `commander contract|plan --dry-run|smoke --dry-run|approval request --dry-run|prompt-lint --kind gpt55-pr` 是 host Codex 指挥官直管微服务 skeleton 入口。当前命令返回 `phase=source-contract`、service/API/state/bridge/prompt/trace/#20/#46/ClaudeQQ 审批边界、.state/commander/ 状态模型、dev 无 daemon smoke contract、dry-run 计划和 GPT-5.5 PR prompt 边界辅助 lint，不接 live bridge、不注入 prompt、不发送 ClaudeQQ。`approval request --dry-run` 会生成 200 字以内中文纯文本 ClaudeQQ 审批草案、`notification-path-unavailable` blocker 和授权后唯一可用的 `bun scripts/cli.ts microservice proxy claudeqq /api/push/text --method POST --body-json '<payload>' --raw` 命令；不得提示使用本机 ClaudeQQ skill、powershell 或本地 server。`prompt-lint` 支持 `--prompt-file` 与 `--stdin`，输出 `ok`、`missingClauses`、`riskLevel`、`suggestedPatchSnippet` 且不回显完整 prompt；它是 commander 辅助检查，不是业务 PR 门禁，也不改变 `codex submit` 默认行为。`plan`、`smoke` 与 `approval request` 必须带 `--dry-run`；缺少时返回 `error=dry-run-required`。长期规则见 `docs/reference/host-codex-commander.md`。
 - `hwlab g14 monitor-prs [--once] [--dry-run] [--interval-seconds N] [--max-cycles N] [--timeout-seconds N]` 是当前 HWLAB G14 PR -> CI/CD -> DEV rollout 的一行式入口。普通调用创建 `.state/jobs/` 异步 job 并立刻返回 `job.id`、`statusCommand` 和 stdout/stderr 路径；后台 worker 每轮通过 UniDesk `gh pr list/preflight/merge` 监控 `pikasTech/HWLAB` base=`G14` 的 open PR，ready 时合并，然后通过 UniDesk `ssh G14:k3s` 观察 `hwlab-g14-ci-poll-<short>`、Argo `hwlab-g14-dev` 和 DEV `/health/live`，直到 DEV `Synced/Healthy` 且 Deployment/StatefulSet ready；历史 `Completed` smoke/debug pod 不作为 rollout blocker。每次成功 DEV rollout 后，worker 会定位或创建 #7“指挥简报索引”中的北京日期每日简报 issue，并追加 CI/CD 耗时、CI/CD 关键指标、语义化上线 changelog、自动 diff 摘要、PipelineRun、GitOps revision 和 DEV 验证摘要；关键指标来自 G14 Tekton TaskRun results，固定包含 `lazy build reused: x/y`、reused services、rebuild services 和每个 service 的独立耗时/状态/backend，用于观察 lazy build 机制效果。语义化 changelog 优先从 PR body 的 `## 修改`/`## 变更`/`## Changelog` 等段落提取，diff 摘要只作为文件和统计证据保留，不替代 changelog。也可用 `hwlab g14 record-rollout --pr <number> --source-commit <sha>` 手动补记，手动补记同样会按 PipelineRun 采集 TaskRun 指标。状态指针按用途分离：长期监控只写 `.state/hwlab-g14/latest-monitor-job.json`，`--once` 写 `latest-once-job.json`，`--dry-run` 写 `latest-dry-run-job.json`，`--once --dry-run` 写 `latest-once-dry-run-job.json`，避免一次性收口覆盖持续监控入口。`--once --dry-run` 只做单轮监控和 merge plan，不写 GitHub、不等待 rollout。该命令禁止使用原生 `gh` 或手拼 GitHub 请求；如果 UniDesk `gh` 子命令字段或行为不够，必须先改进 `scripts/src/gh.ts` 后再使用。

+- `hwlab g14 control-plane status|apply --lane v02 [--dry-run|--confirm]` 是 HWLAB `v0.2` 加法 lane 的受控 Tekton/Argo 控制面维护入口，只面向 G14 `/root/hwlab-v02`、branch `v0.2`、namespace `hwlab-ci` 和 Argo application `hwlab-g14-v02`；`status` 只读汇总 pipeline、RBAC/ServiceAccount、Argo、当前 commit PipelineRun 和遗留 v02 CronJob 清理状态；`apply` 先在 G14 workspace 快进并执行 render check，再经 `G14:k3s` server-side apply `tekton-v02/rbac.yaml`、`pipeline.yaml`、`argocd/project.yaml` 和 `argocd/application-v02.yaml`，confirmed apply 会删除遗留 v02 CronJob，但不会应用 runtime-v02 workload、Secret 或数据迁移。
+- `hwlab g14 control-plane trigger-current --lane v02 [--dry-run|--confirm]` 是 v02 标准手动触发入口：解析当前 `origin/v0.2` full SHA，创建 commit-pinned `hwlab-v02-ci-poll-<short12>` PipelineRun；读 Git 走 `git-mirror-http.devops-infra.svc.cluster.local`，GitOps promotion 写 `git-mirror-write.devops-infra.svc.cluster.local`；同名 PipelineRun 成功或运行中时拒绝重复触发，失败或不存在时才删除旧对象并重新创建；旧 `rerun-current` 只作为输入别名保留。
+- `hwlab g14 control-plane runtime-migration --lane v02 [--dry-run|--allow-live-db-read --dry-run|--confirm]` 只通过 `hwlab-v02` namespace 当前 `deployment/hwlab-cloud-api -c hwlab-cloud-api` 内 repo-owned migration CLI 执行；不读取或打印 Secret 值、不触碰 PROD、不绕到手工 `psql`。
+- `hwlab g14 control-plane cleanup-runs --lane v02|g14|all [--min-age-minutes N] [--limit N] [--dry-run|--confirm]` 是完成态 PipelineRun 工作区 retention 入口；真实清理只删除已完成 PipelineRun，让 Tekton/local-path 回收临时 PVC，不触碰 registry storage、业务 PVC、Secret、runtime workload 或 GitOps desired state。
+- `hwlab g14 control-plane cleanup-released-pvs --lane all [--limit N] [--dry-run|--confirm]` 是 local-path 未自动回收后的补充 retention 入口；只列并删除 `Released`、`local-path`、`Delete`、`claimNamespace=hwlab-ci` 且 claim 名称形如 Tekton 临时 `pvc-*` 的 PV。
+- `hwlab g14 git-mirror status|apply|sync|flush [--dry-run|--confirm]` 是 `devops-infra` git mirror/relay 的受控维护入口：`apply` 渲染并 server-side apply `devops-infra/git-mirror.yaml`，同时删除遗留 `git-mirror-hwlab-sync` CronJob；`sync` 创建一次性 manual Job，把 GitHub allowlist refs 拉入本地 mirror；`flush` 创建一次性 manual Job，把本地 `v0.2-gitops` 快进推回 GitHub；`status` 返回 read/write URL、last sync/write/flush、本地 ref、GitHub staging ref 和 pending flush 状态；mirror 不设置 CronJob。
+- `hwlab g14 tools-image status|build --name ci-node-tools --tag <tag> [--dockerfile deploy/ci/hwlab-ci-node-tools.Dockerfile] [--dry-run|--confirm]` 是 G14 固定 HWLAB CI tools image 的受控 host build/push 入口；构建和 push 只发生在 G14 host 与本地 registry，不在 master server 构建，也不把 `apk add`/runtime install 塞进 Tekton PipelineRun。
 - `ssh gh:/owner/repo ...` 把 GitHub issue/PR 映射成只读/受控写入的虚拟文本目录，适合日报、PR 正文和 issue 正文的小补丁维护：`ssh gh:/pikasTech/HWLAB ls` 展示 `pr/` 与 `issue/`，`ssh gh:/pikasTech/HWLAB/pr ls [--limit N] [--full]` 和 `ssh gh:/pikasTech/HWLAB/issue ls [--limit N] [--full]` 展示条目状态、楼层数、正文长度和标题，`ssh gh:/pikasTech/HWLAB/pr/507 ls` 展示单个 PR 的一楼正文文件，`ssh gh:/pikasTech/HWLAB/505/1 cat|rg|patch-apply` 兼容旧式 issue/PR number route。`patch-apply` 使用 UniDesk 默认 apply-patch v2 的虚拟文件 executor，把正文一楼映射为 `body.md`，写回仍走 `bun scripts/cli.ts gh issue/pr update` 的 guard/concurrency 规则；`rm` 对正文一楼结构化拒绝，避免误删 issue/PR 正文。大正文读取必须展开 UniDesk gh dump 文件，否则 `cat/rg/patch-apply` 会误读为空，这是 `gh:` 虚拟文件接口的 P0 可见性契约。
 - `hwlab cd status|audit|preflight|apply --env dev [--dry-run]` 是旧 D601 HWLAB DEV CD 指挥侧 wrapper，仅用于显式 legacy 诊断和迁移对照。默认通过 UniDesk provider `host.ssh` 进入 D601，再调用 HWLAB repo-owned `scripts/dev-cd-apply.mjs`，不内嵌发布 kubectl 逻辑：`status` 汇总固定 CD mirror、Git clean/main/origin-main、`deploy/deploy.json`/artifact catalog/report、D601 native k3s guard 和 CD Lease lock，并用 `scripts/dev-cd-apply.mjs --status --skip-live-verify` 取得 target/promotion 摘要；`audit` 在 k3s/CD 恢复后做只读健康审计，返回有界 JSON 的 blocker 分类、D601 guard/node、SecretRef 存在性、registry 可达性、Lease phase/holder/staleness、deploy.json 与 artifact/workload image 收敛、current Deployment image/revision/rollout、16666/16667 public health commit/readiness 和 DB/runtime durability 摘要；`preflight` 进一步检查必需 SecretRef 对象/键存在性并运行 HWLAB `scripts/dev-cd-apply.mjs --dry-run --skip-live-verify` 受控事务摘要。完整远端 stdout/stderr 写入 D601 `~/.state/unidesk-hwlab-cd/<run-id>/` 和本地 `.state/hwlab-cd/<run-id>/` task dump，stdout 只返回有界摘要。默认 HWLAB CD repo 是 `/home/ubuntu/hwlab_cd`，`/home/ubuntu/hwlab` runner 历史目录不得作为发布真相。wrapper 强制 `KUBECONFIG=/etc/rancher/k3s/k3s.yaml` 并只以这个显式目标作为 gate；显式目标出现 `docker-desktop`、`desktop-control-plane` 或 `127.0.0.1:11700` 信号会结构化拒绝，audit/preflight/apply --dry-run 都必须观察到 node `d601`。真实 apply 只暴露 `scripts/dev-cd-apply.mjs --apply --confirm-dev --confirmed-non-production --write-report` 命令形状并标注 host-commander-only，本 runner 不执行 live apply、rollout、Lease mutation 或 DEV deploy apply。长期规则见 `docs/reference/hwlab.md`。
 - `gh auth status [--repo owner/name]` 探测 GitHub 操作前置条件并输出脱敏 JSON：是否存在 `gh` binary、是否存在 `GH_TOKEN`/`GITHUB_TOKEN` 或可用 `gh auth token` fallback、REST API 是否可达、目标 repo 是否可见、issue 是否可读。degraded reason 必须归类为 `missing-binary`、`missing-token`、`auth-failed`、`github-transient`、`network-proxy-failed`、`permission-denied`、`repo-not-found`、`repo-forbidden`、`issue-not-found`、`pr-not-found`、`scope-insufficient`、`validation-failed`、`invalid-response` 或 `unsupported-command`，不得打印 token；失败对象必须包含 `runnerDisposition=infra-blocked|business-failed`，runner 应优先用该字段分流。`github-transient` 表示 GitHub DNS/API 连接在收到 HTTP 状态前失败，输出应带 `retryable=true` 或等价 commander action；这不是缺 token、认证失败、权限不足或 PR 语义失败。
