Entering the Insights overview fired every section's reads at once, about two dozen requests on a seeded account, and the server worked through them in a queue: the hero and the first sections waited behind trends, the period review, cycle, signals, rhythm events, health status, breathing, labs and ECG, all far below the fold. The first three sections in the account's own order still mount with the page. Every later one renders a 1 px sentinel until it comes within 400 px of the visible area of the shell's scroll container, then mounts and fetches; once mounted it stays. Measured on a seeded account under a 4x CPU slowdown: 24 -> 13 requests on entry, the entry network span 1.3-1.8 s -> 0.5-0.9 s, LCP about 1.35 s -> 0.9 s, blocking time about 550 ms -> 200 ms. Scrolling to the end still loads all 25 and renders all ten sections. Specs that assert on, measure or scan the lower sections scroll them in first through a shared helper, so their coverage is unchanged.
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.
