  └── deploy-pages   →  clears old files, uploads the exe file + zip to the ‘release nightly’ repository

  windows-msi.yml
  ├── uploads the portable artefact
  ├── builds the MSI with WiX v7
  ├── deletes the old .msi, uploads the MSI to the nightly version
  └── generates and deploys GitHub Pages  ← the 3 URLs are known here
The GitHub Pages page is no longer generated by windows-build.yml but by windows-msi.yml once the MSI is in the release
