The medication detail's notification section decides between the server-side reminder switch and the client-managed chip on `notificationPrefs.medication.clientManaged`, read off `GET /api/auth/me`. That payload never carried the field — the preferences live on their own endpoint, which is not on the app-boot path — so the flag was `undefined` for every account: the chip never rendered, and a person whose phone owns the reminders was shown a switch that no longer decides anything. The write path and the dispatch gate were correct the whole time; only the web reflection was missing its end. The payload now carries the fully-resolved block from the same resolver the dedicated endpoint uses, so the two cannot disagree, and an account that never opted in reads `false` rather than absent. No extra query: the session already loads the row the column sits on. The pair guard over this payload gained the direction that could not see it. It asked that every published field has a reader; a reader with no field was invisible. It now also reads the response types clients declare for this endpoint and holds them against what the route publishes. A typed guard was tried first and does not work here — each consumer declares its own local interface, so the compiler checks every file against its own private claim and agrees with all of them.
e2e/
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.
