  Code-signed. SmartScreen may still warn while a new release builds download reputation.

  Which one?

  MSIX: Windows verifies the signature and every file block before installing. Per-user, no admin, into the protected WindowsApps folder. Settings live in a per-app container that uninstall deletes.

  Installer: classic per-user setup, no admin. For machines where App Installer is removed or blocked by policy.

  Portable: extract the folder anywhere writable and run phosphor.exe. Data stays in PhosphorData beside it. Warns before writing from inside the zip, Downloads, Desktop, Documents or a drive root.

  All three need the WebView2 runtime, included in Windows 11 and current Windows 10. Windows 10 LTSC and IoT lack it and App Installer: use the installer, which downloads WebView2 during setup, or install the WebView2 Runtime (x64 offline installer) first.
