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.
src/components/
React components. The UI primitives are shadcn/ui (new-york style, zinc base) over Radix + Tailwind 4 + Lucide; everything above the primitives is feature-grouped by surface. Components are server components unless they need a hook, state, or browser API, in which case they open with "use client". Charts use Recharts 3 — replacing the chart library requires explicit approval.
Primitives and shell
ui/— shadcn/ui primitives (button, dialog, sheet, table, …). Generated by the shadcn CLI; keep edits minimal and on-style.layout/— the app shell: sidebar, topbar, bottom nav.providers.tsx,version-poller.tsx— top-level context providers and the self-healing stale-shell poller.i18n/— translation context + locale switcher.
Feature groups
insights/— insight status, assessment cards, Coach surface, advisor cards (the largest group).medications/— medication cards, the schedule wizard, intake timeline, detail history.settings/— the section components behind each settings page.measurements/,mood/,dashboard/— entry forms, lists, dashboard tiles.charts/— Recharts wrappers.monitoring/— Umami / GlitchTip client bootstrap.gamification/,targets/,comparison/,doctor-report/,clinician/,onboarding/,admin/— the remaining per-surface groups.
Conventions
Kebab-case filenames; React component exports stay PascalCase regardless. (A handful of PascalCase-filename outliers under medications/ + onboarding/ are pre-existing drift, noted in ../../CLAUDE.md.) Every t() call needs a matching key in messages/en.json — guarded by i18n-call-site-coverage.test.ts. Data reads go through TanStack Query with keys from @/lib/query-keys and unwrap (await res.json()).data. Tests live in __tests__/.
