Constraint: Windows and Linux artifacts are built on native GitHub runners from a temporary snapshot branch
Rejected: Build Windows/Linux locally on Apple Silicon | docker/wine packaging is not stable on this host
Confidence: medium
Scope-risk: moderate
Directive: This snapshot branch is transport-only and should be deleted after the release completes
Tested: local verify/build stages before snapshot creation
Not-tested: remote packaging before workflow execution
3 code paths in desktop.smoke.spec.ts used bare `return` when fixtures
were unavailable (runtime not configured, too few model toggles), which
caused the test to silently pass without exercising the real flow.
Replace with `test.skip(true, reason)` so Playwright reports the skip
and surfaces the missing precondition.
- Add second test to desktop.smoke.spec.ts validating app launch, window dimensions, and screenshot capture
- Screenshot saved to build/screenshots/launch-{platform}.png for D-07 evidence
- Update playwright.config.ts with outputDir for test artifacts and join import
- Add xvfb-run note for headless Linux CI environments
