Start with the linked Windows CI run and inspect nj-build/src/lib.rs around line 35, where the node.lib download failure is reported. Compare the behavior with the regression introduced by pull request 197 and rerun the Windows examples workflow. Done means the Windows CI examples build completes successfully.
