docs/windows.md specified it; this is §9 steps 1, 2 and 4 run, and the report in §10. A Debian trixie image with rustup, the MinGW cross compiler, NSIS and Wine; a build.sh in the shape of the Android one; a package.sh that stages the executable and the seven models behind the same LFS-pointer guard every other packager carries, then runs makensis; and the .nsi itself — per-user, no elevation, an uninstaller that leaves the library alone. Measured: the executable links first time once the link flags were right, imports only Windows system DLLs, prints its version under Wine, and the installer installs and uninstalls silently under Wine with the registry key and the models where §5.2 says. What Wine cannot show is the Start Menu shortcut: CreateShortcut is IShellLink and does nothing headless. Four claims in the spec's first draft were wrong and are corrected in place with the reasoning kept: the whole-archive winpthread flag breaks the link and was never needed; build scripts need a host gcc; bookworm's Wine lacks the bcryptprimitives.dll rustc's std imports, so the image is trixie; and NSIS's default stub is 32-bit, so the installer says amd64-unicode and needs no i386 Wine.
