Struct BaseImageManifest 

pub struct BaseImageManifest {
    pub image_ref: String,
    pub os: String,
    pub os_version: Option<String>,
    pub arch: String,
    pub config_blob: Vec<u8>,
}

Resolved manifest information for the pulled base image.

Carried into BuildSkeleton so task 4.D can populate the final image config’s os / os.version fields without re-pulling the manifest. Task 4.D also reads base_config so the final image’s config.Env / WorkingDir / Entrypoint defaults inherit from the base.

Fields

image_ref: String

Image reference the base was pulled from, e.g. "mcr.microsoft.com/windows/nanoserver:ltsc2022". Preserved for diagnostics and for foreign-layer push paths in task 4.E.

os: String

OCI os value from the resolved manifest’s platform descriptor — always "windows" for a WCOW build, but stored for symmetry with the OCI spec.

os_version: Option<String>

OCI os.version from the resolved manifest’s platform descriptor (e.g. "10.0.20348.2227"). Used as the final image’s os.version unless WindowsBuildConfig::os_version_override overrides it. None when the base manifest omits the field, which is non-conformant for Windows but tolerated.

arch: String

arch from the resolved manifest. Defaults to "amd64".

config_blob: Vec<u8>

JSON of the base image config blob (manifest.config). Stored as raw bytes so task 4.D can hand it straight back through serde_json without forcing this skeleton to take a hard dep on zlayer_registry::image_config::ImageConfig. Empty when the base config could not be fetched (a non-fatal degradation handled in task 4.D).
