Launch evidence

Evidence that the production PWA meets the launch gates. The raw reports and the check script are committed under lighthouse/.

Run conditions

Target	Production, https://mealquest.cubecraftlabs.com
Build	mealquest:743a155
Session	Signed in (household session cookie, supplied at run time)
Date	2026-10-11
Tool	Lighthouse 13.5.0, mobile form factor

The session cookie value is redacted from the committed reports (configSettings.extraHeaders); nothing else in them is changed.

Lighthouse

Reports: lighthouse/2026-10-11/ — one .report.json and one .report.html per page.

Page	Route	Performance	Accessibility	Best practices
Home	/	71	100	100
Plan	/plan	72	100	100
Discover	/discover	66	100	100
Dinner detail	/dinner/<id>	70	100	100

Gate: accessibility ≥ 95 on every page — met (100 on all four). Performance is recorded for reference but is not gated.

Installability

Lighthouse 10 and later removed the PWA category, so installability was checked directly with a Playwright probe: installability-check.mjs. It loads each of the four pages above in a signed-in Chrome session with Playwright's Pixel 5 mobile emulation (viewport, touch, isMobile and mobile user agent; the cookie comes from the CK environment variable, never the file) and gates every page on all of:

• Manifest — the linked manifest is fetched with HTTP 200 and has name "MealQuest", display "standalone", a start_url, and icons at 192x192, 512x512 and one with maskable purpose.
• Service worker — navigator.serviceWorker.ready resolves within 10 seconds (expiry is a failure), and a registration exists whose active worker is activated.

It prints a PASS or FAIL line per condition per page and exits 1 if any condition fails on any page.

Result: PASS on all four pages.
