Build SilverMetal Enhanced - Windows ISO / build (pull_request) Successful in 4m46s
The Welcome wizard showed nothing until WebView2 cold-started and Blazor booted, so the whole startup cost presented as a blank window long enough that operators thought first boot had failed. - Native MAUI splash overlay (renders in the first frame, no WebView2/JIT dependency) + a visually identical in-page splash inside #app, so the native -> webview -> Blazor handoff reads as one continuous loading screen. Fades out on first successful WV2 NavigationCompleted. - PublishReadyToRun=true (publish-only) to remove first-run JIT on the one-shot cold-disk path. R2R header verified present after publish. - Fixed-version WebView2 runtime baked offline next to the exe (build.ps1 stages it, app points WEBVIEW2_BROWSER_EXECUTABLE_FOLDER at it). Removes the Evergreen registry probe and the LTSC "no WebView2 at all" risk flagged in welcome-app-spec.md; air-gap friendly. Absent => falls back to Evergreen. - De-flash launch: drop the `cmd /c` wrapper and add -WindowStyle Hidden in autounattend FirstLogonCommands (kills the console flash + one process). Verified: Release build clean, win-x64 self-contained publish succeeds with R2R confirmed, 38/38 tests pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
