buildah unshare fails on the CI host with memfd_create: Invalid argument, so extract-node-binaries.sh failed right after a successful native build. Exporting an OCI archive needs no mount (the toolchain archive already works that way); extract-oci-files.py reads the files from the layers, later layers win and whiteouts delete.
Build musl and glibc for amd64 and arm64 through one native package path. Reuse musl outputs for OCI images and OpenWrt installers, and export binaries inside a rootless unshare session.
Restore the executable dependency graph into a shared persistent NuGet cache, build managed dependencies once, and run isolated native publishes in parallel.
Clean temporary outputs and expired image layers under store locks, retire inactive legacy stores after seven days, and retain two toolchain exports. Add regression coverage for staging, extraction, packaging and cleanup boundaries.
