Capabilities that keep the site useful under real-world conditions — unreliable connectivity, interrupted sessions, mobile install. Not a compliance score: each row is independent evidence.

Progressive Web Resilience signals (lowest pass rate first).
CapabilityResultWhy it mattersEvidence
Web app manifest declared ✗ 0/1490 pages A web app manifest is required for installability and controls how the app appears when launched. —
Service worker registered ✗ 0/1490 pages A service worker is what makes offline access, caching, and background sync possible. —
Theme color declared ✗ 0/1490 pages Theme color controls the browser chrome/status-bar color when the site is installed or bookmarked. —
Manifest fetched and parsed successfully ✗ 0/1490 pages A manifest that fails to parse cannot drive installability or launch behavior even if the link is present. No manifest declared
Manifest declares a maskable icon ✗ 0/1490 pages A maskable icon lets the OS safely crop/mask the app icon on different device shapes without clipping content. No manifest declared
Service worker is active (not just registered) ✗ 0/1490 pages An active service worker (not just registered) is what actually intercepts requests and serves cached content. —
Service worker controls this page load ✗ 0/1490 pages A controlling service worker means THIS page load is being served/intercepted, not just a future one. —
Meets basic installability criteria ✗ 0/1490 pages Determines whether the browser can realistically offer "Add to Home Screen" / install, based on manifest + service worker + HTTPS together. no readable web app manifest; no service worker registered
Apple touch icon (iOS/bookmark icon) ~ 665/1490 pages iOS uses this icon for home-screen bookmarks and "Add to Home Screen" — without it the icon falls back to a screenshot. —
HTTPS (required for service workers) ✓ 1490/1490 pages HTTPS is required for service workers and most install prompts. —
