# Task 4 Report

## Files

- Added `pwa-e2e.mjs` with production endpoint, manifest, SPA fallback, Chromium install prompt, iOS instructions, standalone/unsupported states, service-worker readiness/source checks, and real browser `/api/health` request verification.
- Updated `README.md` with local production validation, Android/Chrome installation, iOS Safari instructions, standalone behavior, connectivity expectations, and Coolify HTTPS validation guidance.

## Verification

- `node --check pwa-e2e.mjs`: passed.
- `npm.cmd run typecheck`: passed.
- `npm.cmd run build`: passed; Vite produced the production bundle in `dist/`.
- `npm.cmd run test:pwa`: passed; output `PWA checks passed` against the built production server on port 3000.
- `npm.cmd run audit:visual`: passed; 58 screens/visits, 0 failed loads, 0 horizontal overflow issues. The audit reported 8 console 404 messages while still exiting 0.
- `git diff --check`: passed with no whitespace errors. Git emitted existing LF-to-CRLF working-copy warnings for tracked files.

The first PWA run exposed a test-harness race where the synthetic event could fire before React registered its listener. The harness was corrected to dispatch 100 ms after `load`; the subsequent production run passed.

## Self-review

- Endpoint checks use the configured `PWA_BASE_URL`, defaulting to `http://localhost:3000`.
- Manifest assertions cover standalone display, root start URL/scope, and both required icon sizes.
- Browser contexts are isolated for Chromium prompt, iOS Safari instructions, standalone mode, and unsupported/no-event mode.
- Service-worker readiness has a five-second bound, and the source guard checks cover `/api/` and non-GET requests.
- The browser API check observes a real request and validates its JSON response rather than using a fixture.
- No app authentication, tenant data, API route, database schema, or runtime behavior was changed.

## Concerns

- The visual audit continues to record eight pre-existing 404 console messages on some authenticated/admin visits. They were not introduced by Task 4 and were not changed because the task explicitly limits scope to PWA verification and production documentation.
- The report itself and pre-existing `.superpowers/sdd/*` and `graphify-out/*` changes remain outside the Task 4 commit staging set.

## Review Fixes

- Added `fetchWithTimeout()` using `AbortController` for every direct endpoint/source fetch. The in-page `/api/health` request now uses its own bounded `AbortController` as well.
- Added exact-one accessible-action coverage for the login page, authenticated business shell, and authenticated admin shell. Business/admin flows use the existing demo credentials and a mobile viewport so their compact install controls are visible and accessible.
- Replaced fixed sleeps in standalone/unsupported checks with bounded DOM-state polling for zero matching install actions.
- Replaced iOS body-text checks with visible exact-text locators for `Compartir` and `Añadir a pantalla de inicio`.
- Relaxed service-worker source checks to tolerate whitespace and quote style while still requiring the pathname `/api/` bypass and non-GET guard.
- Tracked all browser contexts and closes them explicitly before closing the browser in `finally`; default UI/navigation timeouts are bounded.

## Review-Fix Verification

- `node --check pwa-e2e.mjs`: passed.
- `npm.cmd run typecheck`: passed.
- `npm.cmd run build`: passed; Vite produced the production bundle in `dist/`.
- `npm.cmd run test:pwa`: passed; output `PWA checks passed` against the built production server on port 3000.
- `npm.cmd run audit:visual`: passed; 58 screens/visits, 0 failed loads, 0 horizontal overflow issues. The audit still reports 8 pre-existing console 404 messages.
- `git diff --check`: passed with no whitespace errors; Git only emitted existing LF-to-CRLF working-copy warnings.

## Review-Fix Self-review

- Direct network operations now have bounded completion, including response-body reads for endpoint/source assertions and the browser-side API response.
- Login, business, and admin each assert one and only one accessible `Instalar AgendaMax` action; the two shell checks exercise the authenticated UI path rather than assuming route markup.
- Negative install-state checks wait on the DOM condition with a timeout and fail non-zero if the condition never becomes true.
- All changes remain in the PWA test harness and this report; application behavior and unrelated tests are unchanged.

## Remaining Concerns

- The visual audit's 8 pre-existing 404 console messages remain outside Task 4 scope. They do not cause failed loads, overflow failures, or a non-zero audit exit.

## Service-worker Behavioral Fix

- Added a reload and `navigator.serviceWorker.controller` gate before behavioral API checks, ensuring requests run through an active, controlling worker.
- While online, the browser now verifies `GET /api/health` returns `200` and a safe invalid `POST /api/auth/login` returns `401`.
- With the Playwright context offline, both API requests must produce bounded network errors rather than cached responses. Connectivity is restored in a `finally` block.

## Service-worker Behavioral Verification

- `npm.cmd run typecheck`: passed.
- `npm.cmd run build`: passed; Vite produced the production bundle in `dist/`.
- `npm.cmd run test:pwa`: passed; output `PWA checks passed` against the built production server on port 3000.
- `git diff --check`: passed with no whitespace errors; Git only emitted existing LF-to-CRLF working-copy warnings.

## Service-worker Behavioral Self-review

- The online assertions validate real statuses (`200` and `401`) before offline mode is enabled, so a cached fixture cannot satisfy the positive path.
- Offline assertions require both requests to reject with a network-error result and do not accept a response status or body.
- The offline state is always reverted in `finally`, and the existing bounded request, navigation, worker-readiness, UI, install-surface, and cleanup checks remain intact.
