维护 journal 分阶段记录来源 run、基础镜像重建或复用、artifact 下载、对象合并、镜像组装校验、导出、载入及空闲等待;长操作记录开始和结束耗时,失败输出对应私有 `artifacts/<source-sha>/build.log` 路径。构建的详细下载与 Docker 输出仍只写该日志,不回显 Token、命令环境或认证配置。
快照组装使用宿主 `default` Docker builder,读取已载入宿主的无对象缓存基础镜像;不能使用无法直接读取宿主镜像的独立 docker-container builder。BuildKit 的 `FROM` 不接受裸 `sha256:<Image ID>`,因此维护器在持锁期间将确定的基础 Image ID 绑定到专用临时 `assembly-base` tag,并在组装成功或失败后去除该 tag;来源元数据及 runner 配置仍使用完整 Image ID。临时别名不登记为受管基础镜像,不改变历史镜像的清理归属;进程被强杀时最多残留这一个别名,下次组装会重新绑定并清除。
切换先通过专属入口阻断新的 FetchTask,确认已转发的领取请求全部收到完整上游响应,并检查入口持久化跟踪的已领取任务全部结束、内层 Docker 没有活动容器。任务终态必须依据 Runner 的执行结束及最终上报协议,不能由容器暂时为空、API 已取消或请求超时推断。有任务即恢复领取并延后,不停止任务;状态未知拒绝切换。维护器只需普通账号的 `write:repository` Token(包括查询、下载及定向删除 artifact),不访问全局 Runner 管理 API。切换后等待使用该 Image ID 的完整真实 master push CI 通过,才允许下一次升级及旧镜像清理;不会自动重跑失败用例或为了验收额外触发整轮 CI。首次接管的历史镜像默认不归自动清理管理。
维护状态、凭据、归档和配置备份保存在仓库外。当前版、回滚版、待验证候选、它们的基础镜像及容器引用的镜像均受保护。清理只针对维护器登记的专属 tag、完整 Image ID 和专用目录中的归档;禁止全局 prune。API、构建、验证或空闲检查失败时保留现役镜像与回滚资料,不以失败重跑制造全绿结果。
