 - `decision upload/list/show/health` 通过 backend-core 用户服务代理访问 D601 k3s Decision Center，用于上传会议记录/决议 Markdown、列出权威记录、查看详情和健康检查；它不得直连 D601 Service、NodePort 或 provider-gateway 业务 HTTP。
 - `deploy check/plan/apply` 默认从根目录 `deploy.json` 读取服务 repo 与 commit 期望状态，join `config.json` 和现有 manifest 后使用 target-side build 单一路径校验或更新直管服务与 k3s 代管服务；`deploy plan --env dev|prod` 在 Phase 0 只从固定 Git ref 读取 manifest 并输出 dry-run 环境计划，不使用本地 dirty worktree；规则见 `docs/reference/deploy.md`。
 - `dev-env validate [--manifest path] [--kubectl-dry-run]` 离线校验 D601 `unidesk-dev` namespace、dev PostgreSQL 底座和 dev backend/frontend manifest。默认检查 `src/components/microservices/k3sctl-adapter/k3s/dev/unidesk-dev-foundation.k8s.yaml`；也可显式校验 `src/components/microservices/k3sctl-adapter/k3s/dev/unidesk-dev-core.k8s.yaml`。所有 namespaced 对象必须只落到 `unidesk-dev`，foundation manifest 必须包含 `postgres-dev` StatefulSet/Service、dev secret/config、迁移 Job 和 DB URL guard，core manifest 必须包含 `backend-core-dev`/`frontend-dev` Deployment/Service。加 `--kubectl-dry-run` 时额外执行 `kubectl apply --dry-run=client --validate=false -f <manifest>`，仍不 apply 资源。

 - `codex deploy <commitId>` 是 Code Queue 兼容部署入口，会生成临时 desired manifest 并调用 `deploy apply --service code-queue` 的同一条 target-side build、k3s import、rollout 和 live commit 验证路径；详细规则见 `docs/reference/codex-deploy.md`。
 - `codex submit [prompt] [--prompt-file path|--prompt-stdin] [--queue queueId] [--provider-id id] [--cwd path] [--model model] [--reasoning-effort effort] [--execution-mode mode] [--max-attempts N] [--reference-task-id id] [--dry-run]` 通过 backend-core 私有代理向稳定 `code-queue` 用户服务路径提交任务；prompt 必须且只能来自位置参数、文件或 stdin 之一，`--dry-run` 只返回结构化请求且不实际入队。提交确认和 dry-run 必须返回完整 prompt、字符数和 `truncated=false`，不能套用任务详情的预览截断策略，否则长任务 prompt 无法被人工验收。backend-core 默认把提交、队列 CRUD、已读状态、历史摘要和轻量 Trace 读取分流到主 server `code-queue-mgr`，由它写入主 PostgreSQL；D601 scheduler 只轮询并执行已入库任务。
 - `codex task <taskId>` 通过 Code Queue 私有代理按任务 ID 查询结构化执行摘要；默认只返回有界 prompt/response 预览、执行 Provider、工作目录、最后 assistant message、最近工具调用摘要、attempt、judge、错误、耗时和 trace 翻页提示，适合在新队列任务中引用历史 session 且避免噪声爆炸。该摘要读取默认由主 server `code-queue-mgr` 从 PostgreSQL 返回，不依赖 D601 `code-queue-read` Service 可用。

 The manifest must not create, update, or delete production namespace resources, production DB objects, production PVCs, production Deployments/Services/Secrets, or main server Docker Compose services. Static validation is available through `bun scripts/cli.ts dev-env validate`; Kubernetes client dry-run is `bun scripts/cli.ts dev-env validate --kubectl-dry-run`. If applying manually during Phase 2, the only allowed apply target is this manifest and the post-check must prove production resources are unchanged, for example by comparing `kubectl -n unidesk get deploy,sts,svc,secret,pvc -o name` before and after.
 
+Before applying the foundation on a fresh D601 native k3s runtime, run `bun scripts/cli.ts dev-env prewarm-images` and wait for the returned job to succeed. This imports the foundation images `postgres:16-alpine` and `rancher/mirrored-library-busybox:1.36.1` from Docker into `/run/k3s/containerd/containerd.sock`; k3s/containerd must not depend on live Docker Hub pulls during rollout. If this step is skipped, `postgres-dev` or the local-path helper pod can remain `ImagePullBackOff`, leaving the PVC pending even though the manifest is valid.
+
 Phase 2 guardrails are deliberately limited to the dev manifest and CLI validator. Runtime startup guards for dev backend-core, Code Queue and Code Queue Manager must be reviewed and shipped as a separate change before dev workloads are exposed beyond dry-run or controlled apply.
 
 On D601, dev/prod k3s verification must use the native k3s kubeconfig explicitly: `KUBECONFIG=/etc/rancher/k3s/k3s.yaml`. The default `kubectl` context may point at Docker Desktop and is not an acceptable target for UniDesk k3s deploy validation.
