resolveImage maps placement.image to a configured key or URL; imageCache streams the download through StorageVolUpload with a sha256 tee, writes a marker volume when the upload is verified, and re-fetches when the marker is missing or the configured checksum changed. Errors carry taxonomy sentinels that classify now honours. Adds the in-memory fake libvirt API used from here on. Step 3b of docs/plans/2026-09-04-1404-kvm-provider.md.
