Start with the winget install path that resolves installer architecture, comparing default selection with --architecture arm64 on an Arm64 system. Use the linked 7zip.7zip manifest to verify that ARM64 and x64 installers are available. Done when the default command selects the ARM64 installer while explicit architecture behavior remains correct.
