- Load each settings section on its own: the section route imported all twenty-one statically. A preload starts the chunk beside the record gate's read, and the loading state paints the settings card shell. /settings/[section] goes from 611 to 403 KB gz. - Take Zod out of the shell every route shares: the account-access parse run on each boot is plain TypeScript now, held to the published schema by an equivalence test over good and broken blocks. The canonical unit table moves to its own module, so the display transform no longer pulls Zod in either. Layout entry 199 to 136 KB gz; /insights 369 to 304, /medications 428 to 365, /labs 400 to 337. - Open a saved Coach conversation at its last answer: an instant jump instead of the smooth scroll that lost the end, then follow late layout (charts, tables) for a few seconds until the reader scrolls. - Show the document archive as a month grid of preview tiles, two across on a phone and three or four on a desktop, with the month headings kept. - Add the admin card for the measurement table maintenance: a status read on the maintenance route, one calm confirmation, and the run's state while it is queued, running, finished or stopped. - Re-base the bundle budget: /insights at 304, /settings/[section] watched at 403, aggregate cap 4335 with the reason written down.

End-to-end browser tests. Playwright 1.60 drives a production build of the app against a real PostgreSQL, with @axe-core/playwright for accessibility assertions. This is the heaviest test tier; CI runs it on every PR, and locally it is worth running when a change touches a UI flow.
Running
pnpm e2e
The Playwright config (../playwright.config.ts) builds the app (next build) and brings up Postgres before the specs run; setup/global-setup.ts seeds the auth + fixture state. The suite is not part of the fast local gate (typecheck / lint / test) — it surfaces at PR CI, so expect responsive/wizard/nav reworks to flag here first.
Layout
setup/—test.ts(the suite'stest+expectentry point),global-setup.ts(auth + DB seeding),test-helpers.ts(shared login + navigation helpers).utils/— fixtures such asmock-dashboard-snapshot.ts.fixtures/— synthetic payloads a journey uploads, built in code rather than committed as blobs so the content stays reviewable (apple-health-export.ts).*.spec.ts— one spec per flow: auth/login/redirect, dashboard, charts, the medication-wizard cadences (medications-wizard-*), insights generation + scroll restoration, doctor report, settings, mobile-viewport consistency, locale switch, accessibility (a11y.spec.ts), and thev1427-*regression set.
Conventions
Import test and expect from ./setup/test, never from @playwright/test — types (Page, Route, …) still come from the package. The entry point extends Playwright's test with an automatic fixture that drops route handlers and page listeners after every test, so a handler left in flight cannot fail the test it belonged to once the context closes. src/__tests__/e2e-route-cleanup-guard.test.ts enforces the import boundary.
Assert against stable data-* attributes (data-slot, data-display-step, root display attrs), not viewport-dependent visible text. Responsive sm:hidden UI changes break getByText on desktop while the underlying element is still present — anchoring on data attributes keeps the specs stable across breakpoints. See ../CLAUDE.md.
