 - `fieldlens-print-windows-x64-setup.exe`
 - `fieldlens-print-linux-x64.deb`
+- signed updater artifacts when the persistent Tauri signing key is available
+- `downloads/latest.json` for the signed Tauri updater
+- `downloads/release.json` as the stable installer/version feed
 
 The workflow publishes them to the Gitea release matching the version in `package.json`.
+The desktop app uses the signed Tauri updater where supported and falls back to
+`release.json` for installer-based upgrades such as Debian packages.
