Add pt-BR to the locale list and everything that hangs off it: the client loader, Intl and date-fns mapping, the reply-language footers of the Coach and insights prompts (English body, pt-BR footer, the same path Korean and Dutch take), the citation-coverage normative words, the no-key fallback copy, the AUDIT-C standard-drink line, country labels, period search, CSV yes/no cells and the Telegram bare-word aliases. The locale enums in the extract, managed-profile and record-settings schemas now derive from the locale list instead of repeating it, and the five notification and login-alert routes share one isLocale guard instead of hand-rolled chains, so a later locale is one edit there. A language tag is matched exactly and case-insensitively before its primary subtag, so pt-BR and pt-PT browsers land on the Portuguese bundle rather than English, and AUDIT-C no longer cuts a region tag to two letters. PHQ-9, GAD-7 and WHO-5 are not marked validated for pt-BR: the wording has not been read against the published Brazilian forms, so readers get the English items plus the existing note.
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.
