 response-loss behavior and remaining gates are frozen in
 [`ADR-0500`](../../../docs/adr/ADR-0500-short-lived-cluster-security-administration-command.md).
 
+An opt-in one-shot Job is available under
+[`operations/security-administration`](./operations/security-administration).
+It is deliberately absent from the shared operations Kustomization. Select
+`base` or `cloudnative-pg`; select a credential-delivery variant only for
+issue/rotate after provisioning a private encrypted RWO PVC. A non-root init
+container copies the kubelet symlink projection into a `0700` memory-backed
+directory with `0600` files before the administrator starts. The Job has no
+Kubernetes API token or RBAC, does not retry, and retains the one-connection
+database ceiling. The exact serial dispatch and cleanup procedure is in the
+operator guide above; production remains gated on the ADR-0501 live K3s,
+PostgreSQL and PVC ceremony.

 Workstation operators may pass an explicit owner-private context to reuse only
 stable client paths:

 最新增量证据（2026-08-25）：
 
+- D-406/ADR-0501（进行中：静态部署契约已验收，live gate pending）：Cluster Security Administration 现在有可选的一次性 Kubernetes Job，而不是要求每个部署者自行拼装。通用 PostgreSQL、CloudNativePG、credential delivery 与组合入口均显式 opt-in，不进入共享 operations；因此 Edge/Standalone 以及默认 Cluster 的 package、依赖、启动路径和常驻资源仍为零增量。Job 固定 non-root/read-only/drop-all、无 ServiceAccount token/RBAC、`backoffLimit=0`、300 秒 deadline、600 秒 TTL、每容器 25m/48 MiB request 和 250m/128 MiB limit；主命令仍只打开一个 admin PostgreSQL connection。新增 stager 保留 kubelet Secret symlink 兼容性，同时以 realpath confinement、`O_NOFOLLOW`、读前/读后 inode 复验和独立大小上限把四个输入复制成 memory-backed `0700/0600` 私有边界，失败时主容器不可启动。issue/rotate 才选择 PVC delivery component，token 只进入唯一 `0600` no-replace 文件。6 个 stager/CLI 测试、4 个静态审计及四种 `kubectl kustomize` 渲染均通过；18-package clean build/test 退出 0，当前 `cluster-admin` 为 `454 total / 451 pass / 3 conditional skip / 0 fail`，backend 为 `1579 total / 1577 pass / 2 conditional skip / 0 fail`，122-module Edge import、Cluster dependency、package boundary、deployment、deployment-lock 与 release-version 审计全部 compatible。本地 Admin 镜像 `sha256:5464f0bbf5aa1302c080b13c9f18aaa89ba418ab5d09a917f5b5b4937c0ede2f` 在 non-root/read-only、无网络/能力、128 MiB/0.25 CPU 下包含并运行固定 stager 入口。真实 K3s + PostgreSQL register/query/issue/replay/revoke、PVC custody、response-loss 与清理证据尚未执行，所以 D-406 不冒充完整生产 ceremony，也不关闭双人复核/break-glass、pepper rotation、audit retention/export/alert 或远程 UI/API 门禁。
+
 - D-405/ADR-0500（已验收）：Cluster Identity/API Credential/Security Audit 现在有首个受审产品入口。`ql3-security-admin` 由既有 `ql3-cluster-admin security` facade 到达同一安装内的固定 target，不新建单文件 package，也不进入常驻 `cluster-control`；每次只执行一个 exact-shape 的 identity register/enable/disable、credential issue/rotate/revoke 或最多 200 条的 keyset audit query，随后关闭单连接 admin PostgreSQL authority。命令使用独立 `ql3-security-administration+jwt` type、`security-administration` purpose、audience 与 generation/revocation ledger，拒绝其他管理面的 assertion；command、assertion、keyset 与 pepper 均来自显式有界文件，不发现 home、ambient Kubernetes context 或默认 credential。issue/rotate token 只经私有目录内 `0600`、`fsync`、hard-link no-replace 文件交付，stdout 仅含 basename 与 SHA-256；精确重放的 `token=null` 不重新生成或发布 secret。默认 PostgreSQL `verify-full`，Pool 最大一个连接，无 listener、daemon、timer、watcher 或后台 retention。`cluster-admin` 完整回归为 `448 total / 445 pass / 3 conditional skip / 0 fail`，新增聚焦测试 19/19、产品 facade 4/4、backend product contract 4/4；18-package clean build/test 退出 0，backend 为 `1575 total / 1573 pass / 2 conditional skip / 0 fail`。真实 arm64 Admin 镜像在 non-root、read-only、无网络/能力、128 MiB/0.25 CPU 下通过 12-command live contract；PostgreSQL 18.6 arm64 physical HA timeline 1→2 的 147 gates 全部通过，报告 SHA-256 为 `8fbb606773080dae15de5e31db5726abb8700862b51e4616b5f3f50e0b8374f3`。package、Cluster dependency、122-module Edge import、部署、镜像与 service bridge 审计全部 compatible，Edge/Standalone package、依赖和常驻资源不变。本切片关闭 ADR-0050“只有 application service、没有受审产品入口”的缺口，但不冒充远程 HTTP/API/UI、双人复核/break-glass、pepper rotation、audit retention/export/alert 或完整 Kubernetes Job ceremony。
 
 - D-404/ADR-0499（已验收）：Cluster Worker 现在有可选的直接外部 Secret custody adapter，而不再只能依赖 Kubernetes Secret value projection。`vault-kv-v2` 位于既有 `@qinglong/cluster-control` Remote Execution 子域，只有显式选择 provider 的 Cluster 进程才动态加载；基础部署继续使用 `mounted-files`，Edge/Standalone 不新增 package、依赖、daemon、timer、watcher、连接池或常驻内存。adapter 只在 durable Run/Attempt/Lease/Worker Session/execution digest/SecretRef authority 通过后，用 `SHA-256(canonical SecretRef)` 路径读取 KV v2；只接受显式私有 CA 的 TLS 1.3、每次重新打开的短期 orphan/non-renewable service token 和唯一精确 policy，不跟随 redirect、不使用系统 CA 回退、不缓存值或 token。Kubernetes overlay 删除 value Secret projection，只挂载 CA 与 token；普通 Secret、opaque environment bundle 和总响应仍受原 16/96/256 KiB 边界约束，空 Secret 保持合法，异常 envelope、metadata、digest、token、TLS 或 Vault availability 均失败关闭且不回退。真实 arm64 Vault 1.21.4 gate 已完成 3-share/2-threshold init、两个普通 Secret 与一个 bundle、value/token 原子轮换、旧 accessor revoke、缺失 material、不可信 CA、seal/unseal 与同持久存储容器替换；capability-free `0600` content-free 报告 SHA-256 为 `281fe542e1bf6078132216b9701a28e76f36dcbccc95367997d8457773a9c210`，audit 为 `compatible=true/findings=[]`。live fixture 以非 root、read-only rootfs、`cap-drop=ALL`、零新增 capability、`no-new-privileges` 与 `memory-swappiness=0` 运行，并为原生 hosted runner 的 capability/lock 差异显式关闭 fixture mlock；生产 Vault host 的 swap/mlock 硬化不由该门冒充。Cluster Control 为 `279 total / 277 pass / 2 conditional skip / 0 fail`，backend 为 `1574 total / 1572 pass / 2 conditional skip / 0 fail`，18-package clean build/test 退出 0；package、Cluster dependency、122-module Edge import、部署和 14 档 Local artifact 审计全部 compatible，基础 Edge/Standalone 仍为 `2,669,390 / 2,669,468 bytes`、325 files、58 modules。共享 CI 新增原生 x64/arm64 live matrix。该 fixture 关闭 QingLong 直接 custody adapter/data-boundary 门，不冒充生产 Vault HA、KMS/HSM seal、审计设备或灾备证明；ADR-0491 现在只剩固定低性能物理 Edge 的真实空间、RSS/I/O、写放大、ENOSPC 与断电恢复门。

+# ADR-0501：可选的一次性 Kubernetes Security Administration Job
+
+- 状态：Accepted
+- 日期：2026-08-25
+- 决策：D-406
+- 关联：ADR-0050、ADR-0129、ADR-0276、ADR-0301、ADR-0500
+
+## 背景
+
+ADR-0500 已提供无 listener、单命令、单数据库连接的 `ql3-security-admin` 产品入口，但 Cluster 部署者仍需自行编写 Job、Secret 投影、网络策略和 credential delivery。自行组合容易把 admin credential 放入常驻 `cluster-control`、为 Job 挂载 Kubernetes API token、直接让宽权限 Secret 文件成为命令输入，或把新签发 token 留在日志和易失卷中。
+
+QingLong 同时服务低性能路由设备、单机和多节点集群。Cluster 运维能力不能增加 Edge/Standalone package、依赖、启动路径或常驻资源；仅共享同一 Cluster Admin 镜像与故障生命周期的输入适配器也不应拆成单文件 workspace package。
+
+## 决策
+
+### 1. Job 必须显式选择且一次只执行一个操作
+
+在 `deploy/kubernetes/ql3-cluster/operations/security-administration/` 提供通用 PostgreSQL、CloudNativePG、credential delivery 和二者组合的 Kustomize 入口。它们不进入共享 `operations/kustomization.yaml`，操作者必须显式 `create`；Job 设置 `backoffLimit=0`、300 秒 deadline、600 秒完成后 TTL，不运行 listener、timer、watcher 或 sidecar。
+
+ServiceAccount 和 Pod 都关闭自动 token 挂载，不创建 Role、RoleBinding 或 ClusterRole。Job 只有 DNS 与受审 PostgreSQL egress；CloudNativePG overlay 精确限制到 `cnpg.io/cluster=ql3-postgres` 的 TCP 5432。通用 base 默认没有任意 PostgreSQL egress，部署者必须在私有 overlay 中为实际数据库增加精确目的地。
+
+### 2. Kubernetes Secret 不是命令的直接私有文件边界
+
+Secret volume 必须兼容 kubelet 的版本目录与 symlink 投影，默认 `0440` 以便固定的非 root group 读取；但 ADR-0500 的命令拒绝 symlink 和 group/world 权限。因此在既有 `@qinglong/cluster-admin/security-administration` 内增加专用 init stager，而不新建 package。
+
+stager 只接受固定的 `command.json`、`assertion.jwt`、`keyset.json` 和 `pepper`，分别有 64 KiB、16 KiB、256 KiB 与 256 B 上限。它解析 kubelet symlink 后仍要求 realpath 留在投影 authority 内，以 `O_NOFOLLOW` 打开最终文件，复验类型、权限、大小和读前/读后 inode 状态，再清零源 Buffer。目标目录必须不存在，由 stager 创建为 `0700`；文件以 `0600`、`fsync` 和 hard-link no-replace 发布到 1 MiB memory-backed `emptyDir`。任何输入失败都清理已发布目标，主容器不会启动。
+
+### 3. 数据库和进程权限保持最小化
+
+两个容器固定 UID/GID/fsGroup 10001、RuntimeDefault seccomp、只读 rootfs、drop all capabilities、禁止 privilege escalation；每个容器 request 为 25m/48 MiB，limit 为 250m/128 MiB。主容器直接执行同镜像的固定 Security Administration CLI，不经 shell，也不读取 ambient kubeconfig、home 或默认 credential。
+
+通用 base 从独立 Secret 读取 `QL3_POSTGRES_ADMIN_URL`、TLS server name 和 CA。CloudNativePG overlay 使用 `ql3-postgres-admin-auth`、`ql3-postgres-rw` 和 `ql3-postgres-ca`；runtime、migration 和其他管理角色不能代替 `ql3_admin`。应用层仍强制 `verify-full`、显式 DNS server name、一个 Pool connection 和短连接生命周期。
+
+### 4. Credential 交付是独立 opt-in capability
+
+Identity 变更、revoke 和 audit query 使用无 delivery 的 base。只有 `credential.issue` / `credential.rotate` 选择 credential-delivery component；它要求调用方预置受加密和访问控制的 RWO PVC。init stager 在 PVC 内创建或复验 `0700` 私有目录，主容器只向操作者指定的唯一新文件执行 ADR-0500 的 `0600` no-replace 发布。token 不进入 stdout、日志、Secret patch、API response 或易失 `emptyDir`。
+
+固定示例文件只含占位符且不被任何 Kustomization 引入。每次 dispatch 必须使用新的 mutation ID、短期 assertion 和唯一 delivery 文件名；固定资源名使当前基线只支持受控的串行 ceremony，Job 与输入 Secret 完成后必须显式清理。并发 dispatch、自动命名和 delivery acknowledgement 属于后续产品化门禁。
+
+## 被拒绝的替代方案
+
+### 默认安装 Admin Deployment 或 CronJob
+
+拒绝。它会把高权限数据库凭据、pepper 和资源成本变成常驻面，并影响不使用该能力的集群与低配设备。
+
+### 直接把 projected Secret 交给主命令
+
+拒绝。kubelet 的 symlink 和 group-readable 投影与 ADR-0500 的 POSIX 私有文件契约不同，放宽主命令会同时削弱工作站路径。
+
+### 给 Job Kubernetes Secret 读写权限并写回 token
+
+拒绝。API token/RBAC 会扩大 blast radius，更新 Secret 还引入资源版本竞争、日志/审计暴露和难以证明的响应丢失语义。
+
+### 新建 Kubernetes Stager workspace package
+
+拒绝。它只由同一 admin 镜像、同一 Security Administration ceremony 使用，没有独立发布、依赖、权限或故障生命周期；拆包会重新制造单文件 package。
+
+## 验证
+
+- stager 聚焦测试覆盖真实 kubelet symlink 布局、`0700/0600` 收紧、持久 delivery 目录复验、realpath 逃逸、world-readable material、目标不可覆盖和 CLI 无敏感回显。
+- 部署审计冻结无 API token/RBAC、caller-driven/零重试/deadline/TTL、non-root/read-only/drop-all、资源上限、固定 CLI、内存私有输入、独立 admin credential、CloudNativePG egress、PVC delivery 和默认聚合不可达；失败注入覆盖权限扩大、非持久 delivery 与误入共享 aggregate。
+- `kubectl kustomize` 已分别渲染 base、CloudNativePG、credential-delivery 和 CloudNativePG + delivery 四个入口。
+- 18-package clean build/test 退出 0；当前 `cluster-admin` 为 454 total / 451 pass / 3 conditional skip / 0 fail，backend 为 1579 total / 1577 pass / 2 conditional skip / 0 fail。Edge import 仍为 122 modules，Cluster dependency、package boundary、deployment、deployment-lock source surface 与 release-version 审计均 compatible。
+- 本地构建的 Cluster Admin 镜像 digest 为 `sha256:5464f0bbf5aa1302c080b13c9f18aaa89ba418ab5d09a917f5b5b4937c0ede2f`；新 stager 在 non-root、read-only rootfs、`network=none`、drop-all、no-new-privileges、32 PID、128 MiB 与 0.25 CPU 下完成独立 `--help` smoke，证明发布镜像包含该固定入口。
+- 真实 K3s Pod、PostgreSQL admin operation、PVC token custody、response loss 与清理演练尚未执行，因此不得把本 ADR 解释为 live ceremony 已验收。
+
+## 影响与剩余门禁
+
+D-406 关闭“每个部署者都要从零编写一次性 Admin Job”的静态部署缺口，且 Edge/Standalone 和默认 Cluster 常驻资源保持不变。下一门是以临时 K3s + PostgreSQL 执行 register/query/issue/replay/revoke、证明 token 仅存在于 PVC no-replace 文件、Pod 无 API authority、失败清理和证据 content-free；之后仍有双人复核/break-glass、pepper rotation、audit retention/export/alert、并发 dispatch 和远程管理 UI/API。

+## Kubernetes 一次性 Job

+- `cloudnative-pg`：使用 `ql3-postgres-admin-auth`、`ql3-postgres-rw`、`ql3-postgres-ca`；
+- `credential-delivery`：在 base 上增加调用方提供的 RWO PVC；
+- `cloudnative-pg-credential-delivery`：CloudNativePG 与 PVC 交付的组合。
+
+把 `input-secret.example.yaml` 复制到仓库外的私有目录，替换四个占位值，并保持 `immutable: true`。示例不属于任何 Kustomization。非签发操作不要选择 delivery overlay；`credential.issue` / `credential.rotate` 必须先按 `delivery-pvc.example.yaml` 创建受加密、受访问控制的 PVC，并把 manifest 中的 `replace-with-unique-delivery.json` 改为本次唯一文件名。
+
+以 CloudNativePG 的无 delivery audit query 为例：
+
+```sh
+kubectl create -f /secure/qinglong3/security-administration-input.yaml
+kubectl kustomize \
+  deploy/kubernetes/ql3-cluster/operations/security-administration/cloudnative-pg \
+  | kubectl create -f -

+kubectl logs job/ql3-security-administration -n qinglong3-system \
+  -c administrator
+```
+
+当前固定资源名只允许串行执行。收集 content-free 结果和（仅 issue/rotate）PVC 中的 `0600` delivery 文件后，删除 Job 与本次 immutable input Secret；不得重用 assertion、把 token 复制到终端输出，或以 `kubectl apply` 修改旧 Job。真实 K3s + PostgreSQL live ceremony 尚未验收，生产启用前仍需完成 ADR-0501 的 live gate。
