F1: the probe now gates each page on manifest HTTP 200, name, display, start_url, 192x192 and 512x512 icons, a maskable icon, and a service worker that is ready, registered and activated. It prints a PASS/FAIL line per condition and exits 1 if any condition fails on any page. LAUNCH.md lists exactly these gates; the unchecked claim that the worker controls the page is removed. F2: navigator.serviceWorker.ready is raced against a 10 second timeout; expiry fails the "service worker ready" condition. F3: the browser context uses Playwright's Pixel 5 mobile emulation (viewport, touch, isMobile, user agent), and LAUNCH.md says so. Re-run against production mealquest:743a155 on 2026-10-11: every condition PASS on all four pages, exit 0.
