+# Job API v1alpha1 草案
+
+- 状态：Draft
+- 日期：2026-09-17
+- API group：`execution.ayatori.ddupan.top`
+- Kind：`Job`
+- Scope：Namespaced
+
+## 目标
+
+`Job` 表达一次有限时长、有明确退出结果的机器执行。调用者描述任务载荷和资源需求，平台
+选择 execution backend 并持续观察，直到任务成功、失败或取消。
+
+首个 adapter 使用 Kubernetes `batch/v1 Job`，第二个 adapter 使用 OpenSandbox lifecycle
+与 execd API。API 不暴露 PodSpec、sandbox ID 创建参数或具体 adapter 配置，但允许表达两个
+真实后端共有的 OCI image、进程、环境变量和资源语义。
+
+`Job` 是短生命周期控制对象。完成后依据 `ttlSecondsAfterFinished` 回收，长期业务状态由调用
+者保存，日志由 observability 平台保存。详细保留策略见 ADR-0005。
+
+## 非目标
+
+v1alpha1 不提供：
+
+- DAG、workflow 或多步骤 task；
+- 定时执行与可复用 Job template；
+- 并行 completions、indexed job 或 gang scheduling；
+- 自动业务重试；
+- 暂停后恢复；
+- 交互式 shell、endpoint、snapshot 或长生命周期 sandbox；
+- workspace、cache、artifact 上传协议或结构化 task outputs；
+- 永久 Job history。
+
+上述能力应由后续独立资源或经过真实需求验证的兼容字段提供，不能通过透传 PodSpec 或
+OpenSandbox extensions 提前进入 API。
+
+## 示例
+
+```yaml
+apiVersion: execution.ayatori.ddupan.top/v1alpha1
+kind: Job
+metadata:
+  generateName: hello-
+  namespace: ci
+spec:
+  jobClassName: default
+  task:
+    image: docker.io/library/alpine:3.22
+    imagePullSecrets: []
+    command: ["/bin/sh", "-c"]
+    args:
+      - echo "hello ${TARGET}"
+    workingDir: /workspace
+    env:
+      - name: TARGET
+        value: world
+      - name: TOKEN
+        valueFrom:
+          secretKeyRef:
+            name: example-token
+            key: token
+      - name: CONFIG_VALUE
+        valueFrom:
+          configMapKeyRef:
+            name: example-config
+            key: value
+  resources:
+    requests:
+      cpu: 100m
+      memory: 128Mi
+    limits:
+      cpu: "1"
+      memory: 512Mi
+  activeDeadlineSeconds: 600
+  ttlSecondsAfterFinished: 3600
+  desiredState: Running
+```
+
+## Spec
+
+```yaml
+spec:
+  jobClassName: string
+  task: TaskSpec
+  resources: ResourceRequirements
+  activeDeadlineSeconds: int64
+  ttlSecondsAfterFinished: int32
+  desiredState: Running | Cancelled
+```
+
+### `jobClassName`
+
+可选。引用平台管理员维护的 cluster-scoped `JobClass`。调用者选择服务等级或执行
+能力，而不是直接选择 adapter driver。省略时由 namespace policy 解析默认 class；不存在
+默认值时 Job 保持未接受状态，不得静默选择任意后端。
+
+一旦 Job 被接受，该字段不可变。解析出的实际 class 写入 status，以便默认策略后来变化时仍
+能恢复原执行。
+
+`JobClass` 及其强类型 parameters API 定义后端配置和调度策略。Job API 不暴露
+Kubernetes namespace、OpenSandbox endpoint、API key 或 backend raw configuration。
+
+### `task`
+
+必填，创建后不可变。
+
+```yaml
+task:
+  image: string
+  imagePullSecrets: []LocalObjectReference
+  command: []string
+  args: []string
+  workingDir: string
+  env: []EnvVar
+```
+
+- `image`：必填 OCI image reference。首版允许 tag；生产策略可以通过 admission 要求 digest。
+- `imagePullSecrets`：可选，同 namespace 的私有 registry 凭据引用。
+- `command`：可选，覆盖 image entrypoint；空值表示使用 image 默认值。
+- `args`：可选，传给 entrypoint/command。
+- `workingDir`：可选；为空时使用 image/backend 默认值。
+- `env`：可选，名称必须唯一。
+
+`command` 和 `args` 使用 argv 语义，不隐式经过 shell。需要 shell 展开时，调用者必须显式
+指定 `/bin/sh -c` 等命令。
+
+#### 环境变量
+
+```yaml
+- name: EXAMPLE
+  value: literal
+
+- name: TOKEN
+  valueFrom:
+    secretKeyRef:
+      name: example
+      key: token
+      optional: false
+```
+
+`value` 与 `valueFrom` 必须且只能设置一个。v1alpha1 支持同 namespace 的 `SecretKeyRef` 和
+`ConfigMapKeyRef`，两者具有相同的引用、optional 和等待语义。Adapter 负责以适合后端且不
+写入 Job status 的方式传递值。引用对象或 key 缺失时 Job 保持未开始并通过 Condition 报告。
+Secret 内容不得复制到 Event、日志或 backend reference；ConfigMap 值虽然不视为机密，也不
+写入 status，避免状态膨胀和不同后端行为不一致。
+
+Kubernetes adapter 保留原生 `SecretKeyRef`/`ConfigMapKeyRef`，由 kubelet 在执行节点解析，
+controller 不读取内容。OpenSandbox create API 只接收已经解析的环境变量值，因此该 adapter
+必须读取引用并把值放入 sandbox create request。JobClass 必须明确允许 Secret 的这种
+传递路径，且 controller 的日志、Event 和 status 不得记录请求正文。未来需要避免把真实凭据
+暴露给 sandbox 进程时，使用 OpenSandbox Credential Vault 或 Ayatori 独立 Credential 能力，
+而不是改变 `SecretKeyRef` 的既有语义。
+
+私有镜像凭据采用 Kubernetes `kubernetes.io/dockerconfigjson` Secret。Kubernetes adapter
+直接传递引用；OpenSandbox adapter 选择与目标 image registry 匹配的条目，并映射到其
+`image.auth` create 参数。无法解析、没有匹配 registry 或所选 OpenSandbox runtime 不支持
+per-request image auth 时，Job 以明确 reason 失败，不得退回匿名拉取后隐藏真实原因。
+
+### `resources`
+
+可选，使用 Kubernetes `resource.Quantity` 表示数值，但不复用完整 Pod
+`ResourceRequirements` 行为。
+
+v1alpha1 支持 `cpu` 和 `memory` 的 requests/limits。Requests 表达准入与调度需求，limits
+表达执行上限。JobClass 可以提供默认值和允许范围；解析后的实际资源写入 status。
+
+Adapter 必须显式验证能否满足请求，不能无提示地忽略 limit。后端无法区分 request 与 limit
+时，其映射规则属于 JobClass，并在 Job 接受前确定。对 OpenSandbox，CPU 和内存
+limits 直接映射为 sandbox VM/container 的 `resourceLimits`；requests 用于 Ayatori 的准入与
+调度，并可由 JobClass 映射到后端 resource request 或 capacity profile。映射失败必须
+显式拒绝或失败，不能静默降低资源保证。
+
+### `activeDeadlineSeconds`
+
+可选，必须大于零。表示从实际执行开始到任务必须终止的最长时间，不包含排队、class 解析或
+后端 provisioning 时间。到期后 controller 请求终止后端，最终以 `Succeeded=False`、
+`reason=DeadlineExceeded` 结束。
+
+后端自身的 timeout 可以作为执行机制，但 Ayatori controller 仍以 `status.startTime` 和观察
+结果维护领域语义。调度等待超时是不同概念，v1alpha1 不提供。
+
+### `ttlSecondsAfterFinished`
+
+可选，必须大于或等于零。语义与 Kubernetes Job 一致：从终态 transition time 起计算，零
+表示立即具备删除资格。该字段在任务完成前后均可修改，但不能保证在既有 TTL 已过期后通过
+延长 TTL 阻止并发删除。
+
+平台应通过 schema、CEL 或 policy 设置最大值和推荐默认值。controller 本身不偷偷填充一个
+无法从 spec 观察到的永久策略。
+
+### `desiredState`
+
+可选，默认 `Running`。允许的状态迁移只有：
+
+```text
+Running → Cancelled
+```
+
+设置 `Cancelled` 表示请求终止当前执行并保留 Job 至 TTL 到期。取消是尽力而为的异步操作；
+只有 adapter 确认执行不会继续后，Job 才进入终态。字段不得从 `Cancelled` 改回 `Running`。
+重新执行必须创建新的 Job。
+
+v1alpha1 不提供 suspend/resume。对任意后端可靠实现 checkpoint/resume 并非共同能力，且暂停
+不应被伪装为取消。
+
+## 不可变性
+
+创建后仅允许修改：
+
+- `spec.desiredState`，且只能单向变为 `Cancelled`；
+- `spec.ttlSecondsAfterFinished`。
+
+`task`、`resources`、`activeDeadlineSeconds` 和 `jobClassName` 均不可变。首选 CRD CEL
+validation 表达这些约束；只有 schema/CEL 无法正确表达时才引入 admission webhook。
+
+Controller reconcile 的技术重试不表示任务重跑。v1alpha1 每个 Job 最多启动一个逻辑执行；
+adapter 必须使用 Job UID 作为幂等键。若请求结果未知，controller 必须先 Observe，不能因为
+网络超时重新创建可能已经开始的执行。
+
+首个 Kubernetes adapter 创建 `backoffLimit: 0`、`restartPolicy: Never` 的原生 Job，避免继承
+Kubernetes 默认的多次业务执行语义。需要重新执行时创建新的 Ayatori Job。
+
+## Status
+

+  result:
+    exitCode: 0
+    reason: Completed
+```
+
+### Conditions
+
+使用标准 `metav1.Condition`。v1alpha1 定义三个核心 Condition：
+
+- `Accepted`：spec、引用、policy 和 JobClass 已解析，可进入调度；
+- `Scheduled`：后端已确定并存在可观察的逻辑执行；
+- `Succeeded`：任务结果。`Unknown` 表示尚未结束，`True` 表示成功，`False` 表示已经失败或
+  取消。
+
+失败不使用单独的 `Failed` Condition。`Succeeded=True` 与 `Failed=True` 会形成需要额外维护的
+互斥状态，而标准三态 Condition 已能完整表达一次执行：运行中为 `Unknown`、成功为 `True`、
+失败为 `False`。失败类型由稳定 reason 区分；这与 Tekton `TaskRun` 的状态约定一致。
+
+不增加与 Conditions 重复的 `phase` 字段。面向 CLI 的阶段摘要由 printer columns 或客户端从
+Conditions 推导，避免两个状态源发生漂移。
+
+常用 `Succeeded` reason 初始包括：
+
+- `Pending`、`Scheduling`、`Running`；
+- `Completed`；
+- `ProcessFailed`；
+- `DeadlineExceeded`；
+- `Cancelled`；
+- `BackendLost`；
+- `ResultUnknown`。
+
+Reason 是稳定、机器可读的 PascalCase 标识；message 面向人类且不得承载程序逻辑。
+
+## 状态机
+
+状态机名称用于设计、测试和 metrics，不增加持久化 `status.phase`。当前状态必须能够从 spec、
+deletionTimestamp、Conditions、时间和 execution references 唯一推导。
+
+### 状态定义
+
+| 状态 | 判定摘要 | 含义 |
+|---|---|---|
+| `Resolving` | `Accepted!=True`，非终态 | 等待 JobClass、Secret、ConfigMap 或 policy 解析 |
+| `Scheduling` | `Accepted=True`、`Scheduled!=True` | 选择 adapter 并幂等创建后端执行 |
+| `Starting` | `Scheduled=True`、无 `startTime` | 后端已存在，任务主体尚未确认开始 |
+| `Running` | 有 `startTime`、`Succeeded=Unknown` | 任务主体正在执行 |
+| `Cancelling` | `desiredState=Cancelled`、非终态 | 正在确认后端已经停止 |
+| `ResultUnknown` | `Succeeded=Unknown/ResultUnknown` | 无法证明任务仍在运行或已经停止 |
+| `Succeeded` | `Succeeded=True` | 成功终态 |
+| `Failed` | `Succeeded=False`，reason 非 `Cancelled` | 失败终态 |
+| `Cancelled` | `Succeeded=False/Cancelled` | 取消终态 |
+| `Deleting` | 存在 `deletionTimestamp` | finalizer 正在停止并清理后端，覆盖其他状态 |
+
+存在多个判定条件时按 `Deleting → terminal → Cancelling → ResultUnknown → Running → Starting →
+Scheduling → Resolving` 的优先级推导，保证状态唯一。
+
+`ResultUnknown` 不是终态，不设置 `completionTime`，也不启动 TTL。只有确认任务已经停止，才能
+转为成功、失败或取消。暂时无法联系后端不等于后端执行失败。
+
+### 正常转移
+
+```text
+Resolving
+    │ 引用与策略解析完成
+    ▼
+Scheduling
+    │ 后端逻辑执行已建立并持久化引用
+    ▼
+Starting
+    │ adapter 确认任务主体开始
+    ▼
+Running ───────────────→ Succeeded
+    └──────────────────→ Failed
+```
+
+后端在任务主体开始前就确定失败，例如 image pull、runtime 不兼容或 provisioning 失败，可以从
+`Scheduling` 或 `Starting` 直接进入 `Failed`，此时 `startTime` 允许为空。
+
+### 取消转移
+
+```text
+Resolving  ─┐
+Scheduling ─┤
+Starting   ─┼→ Cancelling → Cancelled
+Running    ─┤
+ResultUnknown ─┘
+```
+
+尚未创建后端执行时，取消可以立即确认。已经存在或可能存在后端执行时，必须反复执行
+Cancel/Observe，确认不会继续运行后才能进入 `Cancelled`。取消请求与成功完成并发时，以先从
+后端确认到的不可逆事实为准：已经成功完成的任务保持 `Succeeded`，不能改写成 `Cancelled`。
+
+### 不确定结果与恢复
+
+```text
+Ensure/Observe 返回歧义
+          ↓
+    ResultUnknown
+      ├── 找回执行 → Starting / Running
+      ├── 找到终态 → Succeeded / Failed / Cancelled
+      └── 管理员确认无法继续 → Failed(BackendLost)
+```
+
+在 `Ensure` 请求超时且尚未成功写入 external reference 时，adapter 必须使用 Job UID 查询后端，
+不能直接再次创建。Controller 重启后遵循相同规则。
+
+### 删除与 TTL 转移
+
+任意状态收到 deletionTimestamp 后进入 `Deleting`。若执行可能存在，先 Cancel/Observe，再
+Delete 后端资源并移除 finalizer。TTL controller 只对具有 `completionTime` 的三个终态发起
+删除；`Resolving`、`Scheduling`、`Starting`、`Running`、`Cancelling` 和 `ResultUnknown` 均不
+具备 TTL 删除资格。
+
+### 状态不变量
+
+- `Succeeded=True/False` 是不可逆终态；终态 reason、`completionTime` 和 result 不再改变。
+- `startTime` 和 `completionTime` 一旦设置不可改变；两者都存在时 completionTime 不早于
+  startTime。
+- `Succeeded=True` 必须具有 `completionTime`，可以没有 exit code，但 adapter 应说明原因。
+- `Succeeded=False` 必须具有 `completionTime`；进程失败且能取得退出码时必须保存 exit code。
+- 非终态的 `Succeeded` 必须为 `Unknown`，不得省略为具有歧义的空状态。
+- `Scheduled=True` 前不得设置 `startTime`；一旦为 True 不再回退。
+- execution references 只能由 controller 写入；已有引用不能静默替换成新的逻辑执行。
+- Job UID 是执行幂等键；同名但不同 UID 的 Job 必须被视为不同执行。
+- `desiredState=Cancelled` 后不得创建新的后端执行。
+- reconcile 错误和退避不得修改任务的业务结果。
+
+### 状态机测试矩阵
+
+实现必须至少覆盖以下 table-driven unit tests，并为关键恢复路径提供 envtest：
+
+| 类别 | 场景 | 必要断言 |
+|---|---|---|
+| 正常 | 创建、开始、退出 0 | 单次 Ensure，时间与成功终态正确 |
+| 正常 | 主进程非零退出 | `Succeeded=False/ProcessFailed` 与 exit code |
+| 解析 | JobClass 后创建 | 不提前 Ensure，引用出现后继续 |
+| 解析 | Secret/ConfigMap 或 key 后创建 | 不泄露值，解析后只启动一次 |
+| 后端 | image pull 或 provisioning 失败 | 未设置 startTime 的失败终态合法 |
+| 幂等 | Ensure 成功但 status 写入前崩溃 | 通过 UID 找回，不能创建第二次执行 |
+| 幂等 | 重复 reconcile 与重复事件 | 不产生额外执行，不改变终态时间 |
+| 恢复 | controller 在各非终态重启 | 从持久 status/reference 恢复正确状态 |
+| 未知 | Ensure/Observe 超时且结果不明 | 保持非终态，不设 completionTime，不触发 TTL |
+| 未知 | 后端恢复后找回运行任务 | 从 ResultUnknown 返回 Running |
+| 未知 | 管理员确认执行丢失 | 只在确认后进入 `Failed/BackendLost` |
+| 取消 | 在解析、调度、启动、运行阶段取消 | 不再创建或确认停止后才进入 Cancelled |
+| 竞态 | 取消与成功完成并发 | 已确认成功不被取消覆盖 |
+| 超时 | active deadline 到期 | 请求取消，确认停止后 `DeadlineExceeded` |
+| 删除 | 每个非终态阶段删除 | finalizer 清理完成前对象不消失 |
+| 删除 | 后端暂时不可达 | finalizer 保留并重试，不误报已清理 |
+| TTL | 三种终态到期 | 到期前不删，到期后带 UID precondition 删除 |
+| TTL | controller 在等待 TTL 时重启 | informer 恢复计时，最终删除一次 |
+| TTL | 到期附近延长 TTL | 最终 GET 重新核对最新 TTL |
+| 隔离 | 同名 Job 删除并以新 UID 重建 | 旧队列项和旧后端不得影响新 Job |
+| 校验 | 修改不可变字段或取消后恢复 Running | schema/CEL 拒绝请求 |
+| 引用 | OpenSandbox 保存 Sandbox 与 Command 引用 | 顺序重试后引用稳定且无凭据 |
+
+### 时间
+
+- `startTime`：adapter 确认任务主体开始执行的时间，而不是 CR 创建或 backend provisioning
+  时间；设置后不可改变。
+- `completionTime`：进入最终成功、失败或取消状态的时间；设置后不可改变。
+
+TTL 以 `completionTime` 为基准。若后端已经完成但结果暂时无法确认，不得猜测 completionTime。
+
+### Execution reference
+
+`status.execution` 是 execution 领域定义的正式 API 字段，保存 controller 重启后重新 Observe
+所需的最小稳定引用：
+
+- `adapter`：实际 adapter 类型；
+- `references`：一个或多个由 adapter 定义的不透明外部引用。
+
+```yaml
+execution:
+  adapter: opensandbox
+  references:
+    - type: Sandbox
+      id: sandbox-123
+    - type: Command
+      id: command-456
+```
+
+单个 `externalID` 不足以表达 OpenSandbox 的 sandbox 与 command 两级资源。`type` 和 `id` 的
+值由对应 adapter 定义，调用者只能用于诊断和关联，不能据此实现领域逻辑。execution 领域将
+每个引用限制为 `type` 与 `id` 两个非空、有长度上限的字符串，不提供任意 metadata map 或
+raw JSON。引用不包含 endpoint、凭据或 Secret 内容。Kubernetes adapter 可以另外通过 owner
+reference 管理原生 Job，但仍需把恢复所需引用持久化，并保证同名重建安全。
+
+该结构不提升为跨领域共享的万能 ExternalReference。VM、数据库和 LB 等领域根据真实后端
+需要定义自己的受限引用 schema，只有多个领域出现语义完全一致的实际重复后才考虑共享。
+
+### Result
+
+`result.exitCode` 只在后端能够确定主进程退出码时设置。调度失败、取消、后端丢失等情况可以
+没有退出码。`result.reason` 提供简短分类；详细诊断写入 Condition message 和 observability，
+不得把完整日志写入 status。
+
+Job UID 是跨后端日志、metrics 和 traces 的主要 correlation identity。Adapter 必须将
+namespace、name 和 UID 传入执行环境或后端 metadata；高基数字段如何索引由 observability
+平台决定，API 不要求把 UID 配置为日志 label。
+
+## 删除与 finalizer
+
+Execution controller 在可能创建外部执行前添加
+`execution.ayatori.ddupan.top/job-cleanup` finalizer。
+
+删除一个活动 Job 表示取消并清理，而不是 orphan：
+
+1. 请求 adapter 终止执行；
+2. Observe，确认执行不会继续；
+3. 删除后端临时资源与短期凭据；
+4. 移除 finalizer。
+
+首版不提供用户可选 orphan policy。让一次性任务脱离控制面继续运行既难以观察，也可能产生
+副作用。后端长期不可达时由管理员根据 runbook 判断并强制移除 finalizer，该操作必须可审计。
+
+TTL controller 只发起 Job 删除，所有手工删除和 TTL 删除都经过相同 finalizer 路径。
+
+## Adapter contract 对 API 的保证
+
+每个 execution adapter 必须提供以下语义，而非暴露自身 SDK 类型：
+
+```text
+Ensure   幂等地建立以 Job UID 标识的一个逻辑执行
+Observe  返回尚未开始、运行、成功、失败、取消或结果未知
+Cancel   请求停止且可被重复调用
+Delete   清理后端临时资源且可被重复调用
+```
+
+`Ensure` 的网络超时不能直接触发第二次执行。Adapter 必须能够通过 UID/metadata 查找已创建的
+后端对象，或返回 `ResultUnknown` 交由人工处理。
+
+Kubernetes adapter 与 OpenSandbox adapter 实现后，应复审 contract 和 API。只有两个真实
+实现都需要且语义相同的字段才提升为通用能力；后端特有功能优先进入 JobClass 或独立
+资源，不增加 `rawConfig`。
+
+OpenSandbox 支持从 OCI image 创建 sandbox，但不保证每个 image 都能在所选 runtime、架构或
+安全 profile 下成功启动。Adapter 对已知不支持的组合应尽早报告；image pull、进程启动或
+运行时不兼容等实际后端失败最终统一表现为 `Succeeded=False`，并以 reason/message 保留可
+诊断原因。这不要求 Ayatori 在提交前证明任意 OCI image 一定可运行。
+
+## 待后续设计
+
+- capability-based class 自动选择；
+- 私有 image registry 的凭据和统一 workload identity；
+- artifact、workspace 与 cache 的独立 API；
+- Job 创建速率、并发、quota、公平调度以及是否集成 Kueue；
+- observability correlation 的具体 OpenTelemetry/Loki 字段约定；
+- 调用者错过 TTL 时是否需要可选的最小审计记录。
+
+这些问题不阻塞首个 Kubernetes adapter 的 API review；image pull 的最小凭据路径必须在实现
+前通过 Kubernetes 与 OpenSandbox adapter 测试验证。

+# JobClass API v1alpha1 草案
+
+- 状态：Draft
+- 日期：2026-09-17
+- API group：`execution.ayatori.ddupan.top`
+- Kind：`JobClass`
+- Scope：Cluster
+
+## 目标
+
+`JobClass` 是平台管理员提供给 Job 调用者的执行服务等级。名称表达稳定的用户语义，
+例如 `default`、`rootless`、`microvm` 或 `trusted-infra`；调用者不需要知道它当前由 Kubernetes
+还是 OpenSandbox 实现。
+
+JobClass 负责：
+
+- 选择拥有该 class 的 adapter/controller；
+- 引用 adapter 自己的强类型参数对象；
+- 限制允许使用该 class 的 namespace；
+- 提供跨后端一致的资源默认值与范围；
+- 向 Job controller 报告配置是否被接受、后端是否可用。
+
+它不负责保存队列状态、并发配额、Job history 或任意后端 raw config。
+
+## 设计依据
+
+- Kubernetes `RuntimeClass` 使用 cluster-scoped class 将调用者与具体 runtime handler、调度约束
+  和 overhead 隔离。
+- `StorageClass` 允许管理员用稳定名称提供不同服务等级，并由调用者显式或默认选择。
+- Gateway API `GatewayClass` 使用 `controllerName + parametersRef` 将稳定 class API 与实现专用
+  参数分离，并通过 `Accepted` Condition 报告配置有效性。
+- Kueue `ResourceFlavor` 将资源规格与具体节点标签、taint 等 placement 细节分开。
+
+Ayatori 采用 GatewayClass 风格的参数引用，不在 JobClass 中建立随 adapter 数量膨胀的
+union，也不使用 `map[string]any`。
+

+        memory: 16Gi
+---
+apiVersion: execution.ayatori.ddupan.top/v1alpha1
+kind: OpenSandboxExecutionParameters
+metadata:
+  name: microvm
+spec:
+  endpoint: https://opensandbox-api.example.internal
+  apiKeySecretRef:
+    namespace: ayatori-system
+    name: opensandbox-api
+    key: api-key
+  poolRef: microvm
+  requestMapping: AdmissionOnly
+  allowSecretEnv: true
+  allowImageAuth: true
+  allowInsecureHTTP: false
+```
+
+`endpoint` 默认必须使用 HTTPS。隔离的本地开发环境可以显式设置
+`allowInsecureHTTP: true` 使用 HTTP；生产配置不得启用该开关。
+
+## JobClass spec
+
+```yaml
+spec:
+  controllerName: string
+  parametersRef: ParametersReference
+  allowedNamespaces: LabelSelector
+  resources: ExecutionResourcePolicy
+```
+
+### `controllerName`
+
+必填、创建后不可变。使用 domain-prefixed path 标识负责处理该 class 和 Job 的 controller，例如：
+
+```text
+execution.ayatori.ddupan.top/kubernetes
+execution.ayatori.ddupan.top/opensandbox
+```
+
+它是 controller 所有权标识，不是任意可执行插件名称。一个 controller 只能处理自己明确支持
+的名称。未来 adapter 拆成独立 Deployment 时，class 和 Job API 无需改变。
+
+### `parametersRef`
+
+必填、创建后不可变：
+
+```yaml
+parametersRef:
+  group: execution.ayatori.ddupan.top
+  kind: KubernetesExecutionParameters
+  name: rootless
+```
+
+v1alpha1 只允许引用 cluster-scoped 参数对象，并限制 `group`、`kind`、`name` 的长度与格式。
+每个 controller 明确列出支持的 kind；引用 ConfigMap、Secret 或未知 CRD 不被接受。
+
+参数引用只有一层，参数 CRD 可以进一步引用 Secret 等运行配置。禁止嵌套通用参数链和 raw
+JSON，避免 class 成为无法校验的配置转发器。
+
+### `allowedNamespaces`
+
+可选 Kubernetes `LabelSelector`。Job 所在 namespace 必须匹配才可使用该 class。省略表示允许
+所有 namespace；这是显式的管理员选择，而不是用户能力。
+
+该检查由 Job controller 执行，并应尽可能增加 CEL/admission policy 作为快速反馈。用户即使
+知道 privileged class 名称，也不能仅靠设置 `jobClassName` 绕过授权。
+
+Namespace label 在 Job 被接受后发生变化，不中断已经运行的 Job，但影响新的 Job。紧急终止
+使用独立管理员操作，不通过修改 selector 隐式杀死任务。
+
+### `resources`
+
+可选，定义后端无关的 CPU、内存策略：
+
+```yaml
+resources:
+  defaults:
+    requests: {cpu, memory}
+    limits: {cpu, memory}
+  minimum:
+    requests: {cpu, memory}
+    limits: {cpu, memory}
+  maximum:
+    requests: {cpu, memory}
+    limits: {cpu, memory}
+```
+
+规则为：
+
+1. Job 未设置的值由 defaults 补齐；
+2. 解析结果必须满足 minimum/maximum；
+3. CPU 与内存 request 不得大于对应 limit；
+4. 解析后的 effective resources 写入 Job status；
+5. 后续修改 class 不改变已经接受的 Job；
+6. adapter 不能静默降低 effective resources。
+
+只支持 CPU 和内存。GPU、临时磁盘等资源在出现真实后端需求后增加，不先复制完整 Kubernetes
+ResourceList。
+
+Runtime/VM overhead 是 adapter 参数或后端调度实现，不计入用户请求的 task resources。
+Kubernetes adapter 应优先利用 RuntimeClass Pod overhead；OpenSandbox adapter 在其 capacity
+profile 中计算 microVM overhead。
+
+## 默认 class 选择
+
+Job 显式设置 `spec.jobClassName` 时始终优先使用该值。省略时按以下顺序解析：
+
+1. Job namespace annotation
+   `execution.ayatori.ddupan.top/default-job-class`；
+2. 唯一带有
+   `execution.ayatori.ddupan.top/is-default-job-class: "true"` annotation 的 JobClass。
+
+若不存在默认 class，Job 保持 `Accepted=False/NoDefaultJobClass`。若存在多个全局默认值，
+Job 保持 `Accepted=False/AmbiguousDefaultJobClass`，同时产生平台告警；不得模仿
+StorageClass 选择最新创建对象，因为执行隔离与权限不应随创建时间变化。
+
+解析后 Job status 保存：
+
+```yaml
+resolvedJobClass:
+  name: rootless
+  uid: 8aa4...
+  controllerName: execution.ayatori.ddupan.top/kubernetes
+  parametersRef:
+    group: execution.ayatori.ddupan.top
+    kind: KubernetesExecutionParameters
+    name: rootless
+    uid: c413...
+```
+
+Job 后续 reconcile 使用已解析引用，不能因 namespace 默认值或全局默认 class 改变而切换
+adapter。若同名 class 被删除并重建，UID 不匹配，现存 Job 不得自动采用新对象。
+
+## Status
+
+```yaml
+status:
+  observedGeneration: 1
+  conditions:
+    - type: Accepted
+      status: "True"
+      reason: Accepted
+      observedGeneration: 1
+      lastTransitionTime: ...
+    - type: Ready
+      status: "True"
+      reason: BackendReachable
+      observedGeneration: 1
+      lastTransitionTime: ...
+```
+
+### `Accepted`
+
+表示 controller 已识别 controllerName，parametersRef 指向受支持且 schema 有效的对象，通用
+resource policy 自洽。无效 class 使用 `Accepted=False` 和稳定 reason，例如：
+
+- `UnsupportedController`；
+- `InvalidParametersReference`；
+- `ParametersNotFound`；
+- `InvalidResourcePolicy`。
+
+### `Ready`
+
+表示该 class 当前具备接受新执行的基本条件。Kubernetes adapter 检查 RuntimeClass 等集群级
+依赖；具体 namespace 中的 ServiceAccount 在 Job 调度时检查。OpenSandbox adapter 检查参数
+引用、认证材料和后端健康端点。
+
+`Ready=False` 阻止创建新的后端执行，但不改变已经开始 Job 的终态。Controller 仍必须尝试
+Observe、Cancel 和 Delete 已存在执行，不能因 class 不 Ready 而停止清理。
+
+Ready 是观测值，不是容量预留。容量不足、排队和并发配额属于调度系统，不通过 Ready 频繁
+抖动。
+
+## 生命周期与修改
+
+- `controllerName` 和 `parametersRef` 不可变；切换后端必须创建新 class 名称。
+- `allowedNamespaces` 与 resource policy 可以修改，只影响尚未接受的新 Job。
+- adapter 参数对象允许更新 endpoint、Secret 引用和其他运维配置，以支持凭据轮换与故障切换。
+- 参数更新不得使 adapter 为现存 Job 创建新的逻辑执行；Job 中已持久化的 execution reference
+  始终优先。
+
+JobClass controller 添加保护 finalizer。删除 class 前必须确认不存在引用其 UID 的非终态
+Job。终态 Job 已完成后端清理，不阻塞 class 删除；其 TTL 回收不再需要 class 后端配置。
+
+参数对象删除保护由各 adapter controller 负责。在仍有 class 引用时，参数对象不得被无提示
+删除。强制移除 finalizer 是管理员恢复操作，必须有 runbook 和审计记录。
+
+## KubernetesExecutionParameters
+
+这是 Kubernetes adapter 自己拥有的 cluster-scoped 管理员 API，不是 Job 用户 API。首版字段：
+
+```yaml
+spec:
+  serviceAccountName: string
+  runtimeClassName: string
+  scheduling:
+    nodeSelector: map[string]string
+    tolerations: []Toleration
+  podSecurityContext: PodSecurityContext
+  imagePullPolicy: Always | IfNotPresent | Never
+```
+
+首版原生 `batch/v1 Job` 与 Ayatori Job 位于同一 namespace，因此 Secret/ConfigMap、ResourceQuota、
+NetworkPolicy、日志和 owner reference 都保持原生语义。普通调用者只拥有 Ayatori Job 权限，
+不应拥有修改生成的 batch Job/Pod 的权限。
+
+`serviceAccountName` 是每个允许 namespace 中预先提供的同名 ServiceAccount。缺失时 Job 保持
+未调度并报告原因，不回退到 `default` ServiceAccount。
+
+参数允许使用 Kubernetes 强类型的 Toleration 和 PodSecurityContext，因为这是明确属于
+Kubernetes adapter 的管理员 API；这不构成向 Job API 透传 PodSpec。
+
+## OpenSandboxExecutionParameters
+
+这是 OpenSandbox adapter 自己拥有的 cluster-scoped 管理员 API。首版字段：
+
+```yaml
+spec:
+  endpoint: string
+  apiKeySecretRef:
+    namespace: string
+    name: string
+    key: string
+  poolRef: string
+  requestMapping: AdmissionOnly | Native
+  allowSecretEnv: bool
+  allowImageAuth: bool
+```
+
+- endpoint 必须为 HTTPS，Dev 显式允许的本地配置除外；不得包含认证信息。
+- API key 只通过 namespaced Secret 引用，status/Event 不显示内容。
+- poolRef 映射为 OpenSandbox 支持的 pool/profile 选择，不允许 Job 覆盖。
+- `requestMapping=Native` 要求后端忠实接受 requests 与 limits；`AdmissionOnly` 表示 requests
+  只参与 Ayatori 准入，limits 映射为 OpenSandbox resourceLimits。
+- Secret env 与 per-request image auth 都会使 adapter 读取 Kubernetes Secret 并把解析值发送
+  到 OpenSandbox API，必须由管理员分别显式启用。
+
+OpenSandbox 参数不暴露任意 `extensions` map。未来确需使用某项 extension 时，将其提升为该
+参数 CRD 中经过校验的命名字段。
+
+## Condition 与 Job 状态机交互
+
+Job 只有在以下条件同时满足时进入 `Accepted=True`：
+
+- class 已按默认或显式名称解析；
+- class UID 与已解析引用一致；
+- class `Accepted=True`；
+- namespace 符合 allowedNamespaces；
+- Job resources 成功解析并处于允许范围；
+- Job 使用的 Secret/ConfigMap 存在且可以按 optional 语义解析。
+
+`JobClass Ready=False` 时，Job 保持 `Accepted=True`、`Scheduled=False`，等待后端恢复。
+这样 class 配置合法性与当前可用性不会混成同一状态。
+
+若 Job 已经 Scheduled，后续 class Ready 或 namespace label 变化不撤销执行。若 class 或参数
+对象意外消失，controller 仍以 Job status 中的 controllerName、参数 UID 和 execution
+references 尝试恢复；无法安全观察时进入非终态 `ResultUnknown`，不能切换 class 重跑。
+
+## 测试矩阵
+
+实现至少覆盖：
+
+- 显式 class、namespace 默认和全局默认的优先级；
+- 零个与多个全局默认 class；
+- allowedNamespaces 允许、拒绝及接受后 label 变化；
+- unsupported controllerName 和错误 parameters kind；
+- parameters 不存在、稍后出现、UID 删除重建；
+- resource defaults、min/max、request 大于 limit 和 quantity 边界；
+- class policy 更新不改变已接受 Job 的 effective resources；
+- class Ready=False 阻止新 Ensure，但不阻止现存执行 Observe/Cancel/Delete；
+- Kubernetes ServiceAccount/runtime 配置缺失且不回退；
+- OpenSandbox API key Secret 缺失、轮换及后端健康恢复；
+- allowSecretEnv/allowImageAuth 拒绝不允许的 Job；
+- class 删除被非终态 Job 阻止，终态清理后允许删除；
+- 同名 class 或参数对象以新 UID 重建时不劫持现存 Job。
+
+## 延后事项
+
+- class 级并发和速率限制；
+- Kueue LocalQueue/ClusterQueue 映射；
+- capability-based 自动 class 选择；
+- 多集群 Kubernetes executor；
+- GPU、临时磁盘和其他扩展资源；
+- workload identity 与 OpenSandbox Credential Vault；
+- class 成本、优先级与抢占策略。

+# ADR-0004：采用可拆分的模块化 Controller 架构
+
+- 状态：Accepted
+- 日期：2026-09-17
+
+## 背景
+
+Ayatori 将逐步提供任务执行、虚拟机、数据库、负载均衡、对象存储、托管 Kubernetes 和
+人工操作等领域能力。这些能力拥有不同的生命周期、权限、网络位置和后端实现，若直接在
+一个 controller 中相互调用并共享内部状态，后续接入新后端时容易形成代码耦合，也难以
+独立扩缩容、发布和隔离故障。
+
+另一方面，在首个领域能力完成前就拆分为多个独立服务，会立即引入镜像与部署管理、服务
+间认证、版本兼容、分布式观测和故障处理成本，而这些成本尚未由真实运行需求证明。
+
+Job 是首个领域对象。它既是最初的单次任务调度 API，也用于验证领域状态机与 Kubernetes
+Job、OpenSandbox 和未来执行后端之间的适配边界。
+
+## 决策
+
+Ayatori 初期采用模块化单体：多个领域 controller 可以编译进同一个 controller manager，
+但代码、API 所有权和依赖方向按照未来可独立部署的服务边界组织。
+
+### 领域所有权
+
+每个领域模块拥有自己的：
+
+- CRD 与 API 版本；
+- reconciler 和状态机；
+- finalizer、conditions、删除及恢复语义；
+- backend adapter contract；
+- 领域测试。
+
+初始领域包括但不限于 execution、compute、database、networking 和 human operations。领域
+模块不得导入其他领域的内部实现，也不得直接修改其他领域所拥有对象的 spec 或 status。
+
+### 跨领域协作
+
+领域间的持久协作通过 Kubernetes API 对象、typed reference、owner reference 和
+conditions 完成，而不是通过进程内 service 方法调用。
+
+例如虚拟机完成创建后需要执行 provision，应创建或引用 Run 对象并观察其状态，而不是
+直接调用 execution 模块的内部 Go API。更高层的资源组合由专门的领域对象或 GitOps 声明
+完成，不引入统一包装所有底层能力的 Application controller。
+
+该约束使 controller 即使暂时位于同一进程，其通信、失败和恢复行为仍与未来分进程部署
+一致。
+
+### Backend adapter
+
+领域状态机只依赖本领域定义的最小 adapter contract，不依赖 Kubernetes Job、Crossplane、
+OpenTofu、OpenSandbox 或具体厂商 SDK 类型。Adapter 负责：
+
+- 幂等地确保期望外部资源存在；
+- 观察并翻译外部状态；
+- 执行取消、删除或 orphan 策略；
+- 返回稳定的外部引用、能力和分类错误。
+
+不同领域分别定义 adapter contract，不建立能包装所有资源类型的万能 Provider 接口。
+后端不具备的能力必须显式报告，不通过虚假的统一语义隐藏差异。
+
+Crossplane、OpenTofu 和 Ansible 等系统是可替换的 backend 实现或执行机制，不构成 Ayatori
+面向用户的稳定 API。它们的 ProviderConfig、Workspace、playbook 等实现细节不得直接成为
+领域 API 的必填契约。
+
+### 共享代码
+
+默认不建立跨领域的万能 service、repository 或 util 层。共享并非禁止，但必须来自已经
+存在的真实重复，并同时满足：
+
+1. 至少有两个真实调用者；
+2. 重复的行为和语义一致，而不只是代码形状相似；
+3. 调用方对其生命周期和预期演化方向一致；
+4. 共享包不依赖任何具体领域的内部包。
+
+适合共享的通常是机制，例如 conditions 操作、typed reference、重试退避、Secret 引用
+读取、观测初始化和测试环境。领域状态机、资源策略、错误含义及后端选择不得为了消除少量
+重复而抽取到共享层。
+
+共享包使用表达具体职责的窄名称，初期保留在 `internal/shared/`。不建立内容持续膨胀的
+通用 `util` 包，也不在实现稳定前承诺公共 Go API。
+
+### 部署与拆分
+
+controller manager 应支持按领域或 controller 集合选择性启用。初期可以使用一个二进制和
+一个 Deployment；需要隔离时，优先使用同一制品部署为多个 Deployment。只有独立版本和
+依赖关系成为真实需求后，才进一步拆分二进制或仓库。
+
+出现下列任一情况时，应评估拆分部署：
+
+- 需要独立扩缩容或显著不同的 reconcile 并发；
+- 权限边界要求独立 ServiceAccount 与 RBAC；
+- 后端只能从特定网络或节点访问；
+- 沉重、不可信或冲突的 SDK 需要隔离；
+- 一个领域的故障不应影响其他控制循环；
+- 发布节奏或维护责任已经明确分离。
+
+拆分不得改变领域 API，也不应将原本通过 API 对象完成的协作改为同步 RPC 链路。
+
+## 结果
+
+- 首个 Job 实现需要同时建立 execution 状态机和 adapter 边界，不能把 Kubernetes Job
+  细节写入领域模型。
+- 初期避免承担不必要的微服务运维成本，同时保留按权限、网络位置和故障域拆分的路径。
+- Kubernetes API 成为领域间异步协作和恢复边界，领域 controller 必须正确处理最终一致性。
+- 部分机械代码会有意保留重复，直到共享语义被至少两个真实实现证明。
+- 代码评审需要检查跨领域 import、对象写入所有权和后端类型泄漏。
+- 当 Job 同时拥有 Kubernetes Job 与 OpenSandbox adapter 后，应复审 adapter contract，确认
+  它来自真实后端差异而非单一实现假设。

+# ADR-0005：Job 使用短生命周期控制对象与 TTL 回收
+
+- 状态：Accepted
+- 日期：2026-09-17
+
+## 背景
+
+Ayatori 的 `Job` 表达一次有限时长、有退出结果的执行。CI、基础设施 controller 和用户可能
+持续创建大量 Job。若所有 Job CR、后端 Kubernetes Job、Pod、Event 和日志都长期保存在
+Kubernetes 中，etcd、apiserver list/watch、controller cache、备份及恢复会持续承担历史
+数据成本。
+
+Kubernetes API 适合作为活动执行的在线控制与协调面，但不应在没有明确产品需求时兼任无限
+增长的执行历史数据库。当前也尚未证明 Ayatori 必须独立于调用者提供长期历史或审计检索。
+Gitea Actions 等调用方已经拥有自己的执行历史；基础设施 controller 也应把 Job 结果转化为
+所属领域资源的 status。执行日志属于观测数据，应进入统一 observability 平台，而不是由
+Job CR 或专用执行历史存储重复保存。
+
+Kubernetes 原生 `batch/v1 Job` 使用独立的 TTL-after-finished controller 回收完成对象。
+该 controller 只支持原生 Job，不能直接处理 Ayatori CRD，但其基于 informer 与延迟工作队列
+的实现模式可以复用。
+
+## 决策
+
+Ayatori 提供 `execution.ayatori.ddupan.top` API group 下的 `Job` Kind。与 Kubernetes
+`batch/v1 Job` 同名不构成冲突，完整 GVK 明确资源身份。
+
+Ayatori Job 是短生命周期控制对象，不是永久执行记录。首版不要求将结果归档到 PostgreSQL，
+也不引入 `Archived` condition 或 `JobRecord` CRD。
+
+### 终态与 TTL
+
+Job 到达成功、失败或取消终态后保留有限时间，随后由 Ayatori 自己的 TTL controller 删除。
+API 提供与原生 Job 语义一致的 `spec.ttlSecondsAfterFinished`；未设置时是否允许无限保留由平台
+准入策略决定，而不是隐式默认永久保存。
+
+TTL 从 controller 写入的可信终态时间开始计算。TTL controller：
+
+1. watch Job 的新增和更新；
+2. 只处理已终止、设置 TTL 且尚未删除的对象；
+3. 未到期时使用延迟工作队列在到期时间重新入队；
+4. 到期时重新读取最新对象并复核 UID、终态和 TTL；
+5. 使用 UID precondition 发起删除，防止删除同名重建对象；
+6. 由 Job finalizer 完成实际执行后端与临时凭据清理。
+
+Controller 重启后，informer 的初始 LIST 会重新触发现存对象的 reconcile 并重建内存中的延迟
+任务，因此不以周期性全量扫描作为正确性基础。
+
+### 结果消费
+
+调用者必须在 TTL 窗口内观察 Job 终态，并把需要长期存在的业务事实写入自身状态。例如 VM
+provision Job 成功后，VM controller 更新 `Provisioned` condition；之后删除 Job 不影响 VM
+状态。CI 系统负责保存自身 workflow 历史。
+
+Job status 只保存控制和短期诊断需要的结构化结果，不保存完整日志、大型输出或 artifact。
+
+### 日志与 artifact
+
+各 execution adapter 必须为执行实例注入稳定的关联信息，使 stdout/stderr 能由共享
+observability 管道采集，并能够按 Ayatori Job 的 namespace、name 和 UID 查询。Job status
+可以保存查询观测数据所需的关联标识或受控链接，但日志内容及其索引、保留和查询能力属于
+observability 平台。
+
+Job 与后端执行对象的 TTL 应为日志采集提供合理窗口，但 GC 不以日志归档成功作为前置条件，
+避免观测平台故障阻塞控制面资源回收。日志采集延迟、丢失和后端不可用通过 observability
+自身的监控和告警处理。
+
+Artifact 与日志语义不同。调用者需要消费的构建产物、状态文件或结构化输出必须显式写入
+对象存储等持久后端，并通过引用交付；不能依赖日志系统作为 artifact 存储。
+
+### GitOps 边界
+
+一次性 Job 不由 Flux 持续管理。否则 TTL 删除会被视为漂移并重新创建，从而重复执行。GitOps
+可以管理 Job template、schedule、execution class 和策略；CI、CLI、UI 或其他 controller
+通过 Kubernetes API 命令式创建 Job。
+
+### 未来归档
+
+只有出现长期历史查询、统一审计、调用者无法及时消费结果等真实需求时，才引入
+外部 `JobRecord`/History API。届时可以为需要持久化的 retention policy 增加归档流程，并将
+归档成功作为删除前置条件；不要求所有 Job 无条件承担该成本。
+
+## 结果
+
+- etcd 中只保留活动 Job、短期已完成 Job 和需要人工处理的异常 Job。
+- 首版不依赖 PostgreSQL 和对象存储即可完成 Job 纵向切片。
+- 调用者必须正确 watch 或轮询结果；TTL 配置必须为其提供足够消费窗口。
+- 历史日志由共享 observability 平台查询，Job CR 只提供执行关联信息。
+- Job 删除后的历史默认不可从 Kubernetes API 恢复，这是有意接受的语义。
+- TTL controller 是 execution 领域的一部分，可以和其他 controller 编译、部署在同一个
+  controller manager 中。
+- 若未来增加归档，应作为独立产品能力和 retention policy 演进，不改变 Job 作为短生命周期
+  控制对象的基本定位。
