 ## CI 工作流
 
+### Linux runner 的运行环境
+
+Linux workflow 使用 `ci=domain-linux-native`、`platform=linux/amd64` 标签和 Woodpecker `local` backend；步骤里的 `image: bash` 是执行程序，构建工具来自 runner 环境。测试、前端和 Backend 编译使用 .NET 10、Node/npm、Python、clang 和 Zig；Agent/Probe 开发镜像通过 Buildah 构建独立的 NativeAOT builder，再在镜像里编译。
+
+WSL 的 agent 通过 rootless Podman 运行，systemd 模板见 `ci/woodpecker-agent-podman.service`。工具全部在 `packaging/container/Woodpecker.Agent.Containerfile` 中安装，包括 .NET 10 SDK、Node/npm、Buildah、Git、Python、clang、Woodpecker agent/clone 插件和测试用 MsQuic 库；AotAnywhere SDK、Zig 与四个 Linux RID 的 NativeAOT 包由 `NativeAot.Builder.Containerfile` 预热。容器只把 `/home/justme` 作为可写工作区和缓存，不挂载宿主工具目录。连接信息与 7897 代理配置放在宿主 `/home/justme/woodpecker/agent-podman.env`，不要提交密钥。容器允许 `unshare`、提供 `SYS_ADMIN` 和 `/dev/fuse`，以便 Buildah 挂载镜像层；不要通过 `chroot /host` 启动 agent，因为 Linux 会拒绝 chroot 进程创建新的用户命名空间。
+
+以 WSL 的 `justme` 用户运行 `bash ci/build-runner-image.sh` 构建工具镜像，验证后安装 systemd 模板并重启 agent。该脚本使用 Podman 的持久镜像层缓存和 `--pull=missing`，服务启动使用 `--pull=never`；流水线和服务重启都不会执行工具安装。NativeAOT builder 只在 SDK/工具版本或 Containerfile 改变时更新，不受每次开发构建的版本号影响。它按镜像 ID 导出到 `woodpecker/cache/runner-image`，各并行组件/架构的 Buildah store 从本地归档导入一次，之后直接复用镜像。只有所需归档不存在或工具配置改变时，构建脚本才回退到 Containerfile 构建。应用的 NuGet restore 缓存独立持久化在 `woodpecker/cache/nuget/packages`，启动时从镜像复制已有工具包作为初始缓存。
+
+所有镜像构建、索引及签名清单发布脚本通过 `ci/buildah-env.sh` 显式配置 Buildah 的 `graphroot` 和 `runroot`。镜像层继续按组件/架构存放在各自的 `buildah-home` 下，运行状态留在当前 runner 的临时目录；容器内 UID 0 不再使各步骤落到同一个 `/var/lib/containers/storage`。`RUN` 默认使用 `chroot` isolation，避免额外的 OCI runtime/cgroup 嵌套；这与上面禁止的 agent 启动方式是不同阶段。
