+## Languages (i18n)
+
+Both apps support **Portuguese (PT, default) and English (EN)**. The language is
+stored in a `NEXT_LOCALE` cookie and selected via the **PT | EN** switcher in the
+app header.
+
+### Changing language
+
+Click the **PT | EN** pill in the header of either app. The preference is saved
+in a cookie (1-year expiry) — no account change required.
+
+### Adding a new language
+
+1. Create `apps/<app>/messages/<locale>.json` (copy `en.json` as a starting point).
+2. Add the locale to `LOCALES` in `apps/<app>/i18n/locales.ts`.
+3. That's it — the switcher picks it up automatically.
+
+See **[docs/i18n.md](docs/i18n.md)** for the full guide, including the
+key-parity and ICU validation scripts to run before shipping a new language.

+# Internationalization (i18n)
+
+FieldOps ships in **Portuguese (PT, default)** and **English (EN)**. Both apps
+(`operator-pwa` and `admin-web`) are fully translated. This doc explains how it
+works and **how to add a new language**.
+
+## How it works
+
+- Library: [`next-intl`](https://next-intl.dev) (Next.js 15 App Router).
+- **No locale in the URL.** This is an internal app (no SEO), so we use
+  next-intl's "without i18n routing" mode. The locale comes from a
+  **`NEXT_LOCALE` cookie**, not a `/en/...` path prefix. This keeps every route
+  unchanged and avoids any clash with the auth middleware.
+- **Default is `pt`.** A missing or invalid cookie falls back to Portuguese.
+- Dates, numbers and relative times are formatted by next-intl's `useFormatter`,
+  so they follow the active locale automatically (no hardcoded `pt-PT`).
+- Translations live **per app** (not in a shared package) — the two apps share
+  only a handful of strings, not enough to justify a shared package yet.
+
+## File structure (same in each app)
+
+```
+apps/<app>/
+  i18n/
+    locales.ts        # LOCALES, DEFAULT_LOCALE, LOCALE_LABELS, isLocale()
+    request.ts        # reads the NEXT_LOCALE cookie, loads the messages file
+  messages/
+    pt.json           # Portuguese (default)
+    en.json           # English
+  app/
+    layout.tsx        # <html lang={locale}>, NextIntlClientProvider
+    language-switcher.tsx   # the PT | EN pill
+  next.config.ts      # wrapped with withNextIntl(...)
+```
+
+Messages are organised into namespaces (`common`, `auth`, `maintenance`,
+`report`, `home`, `sync`, `errors`, `metadata`) — see the JSON files.
+
+## Changing language (end user)
+
+Click the **PT | EN** pill in the app header. The choice is saved in the
+`NEXT_LOCALE` cookie (1-year expiry); server components re-render via
+`router.refresh()`. No account or DB change involved.
+
+> The switcher currently appears on the **authenticated** screens (operator home,
+> maintenance queue), not on the login/picker pages. A first-time user sees the
+> initial login in PT; once they switch, the cookie persists across logins.
+
+## Adding a new language
+
+Example: adding **French (`fr`)** to the admin-web. Repeat for operator-pwa.
+
+1. **Create the messages file.** Copy `apps/admin-web/messages/en.json` to
+   `apps/admin-web/messages/fr.json` and translate every value. **Keep every key
+   identical** — only translate the values. Leave ICU placeholders
+   (`{email}`, `{count}`) and plural structure (`{count, plural, one {…} other {…}}`)
+   intact.
+
+2. **Register the locale** in `apps/admin-web/i18n/locales.ts`:
+   ```ts
+   export const LOCALES = ['pt', 'en', 'fr'] as const;
+   export const LOCALE_LABELS: Record<Locale, string> = { pt: 'PT', en: 'EN', fr: 'FR' };
+   ```
+
+3. **Repeat steps 1–2 for `operator-pwa`** (copy its `en.json`, add `fr` to its
+   `locales.ts`).
+
+4. **Verify** (see below). The **FR** button then appears in the switcher
+   automatically — no other code changes needed.
+
+> Translating the *values* needs someone who speaks the language. Everything
+> else is mechanical.
+
+## Keeping translations healthy
+
+Two failure modes are NOT caught by `tsc` or the E2E tests (the E2E only run in
+the default PT), so check them whenever you touch translations:
+
+**1. Key parity** — every locale file must have exactly the same keys, or a
+missing key renders as raw text (or throws) when a user switches to it:
+
+```sh
+node -e '
+const fs=require("fs");
+function flat(o,p=""){let k=[];for(const key in o){const np=p?p+"."+key:key;if(typeof o[key]==="object"&&o[key]!==null)k=k.concat(flat(o[key],np));else k.push(np);}return k;}
+for(const app of ["admin-web","operator-pwa"]){
+  const files=fs.readdirSync(`apps/${app}/messages`).filter(f=>f.endsWith(".json"));
+  const sets=files.map(f=>[f,new Set(flat(JSON.parse(fs.readFileSync(`apps/${app}/messages/${f}`))))]);
+  const base=sets[0][1];
+  for(const [f,s] of sets){
+    const missing=[...base].filter(k=>!s.has(k));
+    const extra=[...s].filter(k=>!base.has(k));
+    console.log(`[${app}] ${f}: ${s.size} keys`, missing.length||extra.length?`MISSING ${missing} EXTRA ${extra}`:"OK");
+  }
+}'
+```
+
+**2. ICU syntax** — a malformed plural (e.g. a missing brace) only throws when
+that exact message renders, which the PT-only E2E may never hit:
+
+```sh
+node -e '
+const fs=require("fs"),path=require("path");
+const dir=fs.readdirSync("node_modules/.pnpm").find(d=>d.startsWith("intl-messageformat@"));
+const {IntlMessageFormat}=require(path.resolve("node_modules/.pnpm",dir,"node_modules/intl-messageformat"));
+function flat(o,p=""){let r={};for(const k in o){const np=p?p+"."+k:k;if(typeof o[k]==="object"&&o[k]!==null)Object.assign(r,flat(o[k],np));else r[np]=o[k];}return r;}
+let errors=0;
+for(const app of ["admin-web","operator-pwa"]){
+  for(const f of fs.readdirSync(`apps/${app}/messages`).filter(f=>f.endsWith(".json"))){
+    const loc=f.replace(".json","");
+    const msgs=flat(JSON.parse(fs.readFileSync(`apps/${app}/messages/${f}`)));
+    for(const [key,val] of Object.entries(msgs)){
+      try{new IntlMessageFormat(val,loc);}catch(e){console.log(`ICU ERROR [${app}/${loc}] ${key}: ${e.message}`);errors++;}
+    }
+  }
+}
+console.log(errors?`${errors} ERRORS`:"ALL ICU OK");'
+```
+
+Both should report OK before shipping a new language.
+
+## What is intentionally NOT translated
+
+- **Dynamic content** — workstation names, areas, request descriptions. These
+  are customer data, kept in whatever language the user typed.
+- **Backend tRPC error messages** — almost never surface to the user (the UI has
+  its own messages).
+- The `Credentials` provider labels in `lib/auth.ts` (internal to Auth.js; the
+  custom login UI is what users actually see).
+
+## Future improvements (not done yet)
+
+- Persist the locale per tenant/user in the DB (currently cookie-only).
+- Show the language switcher on the login/picker pages too.
+- A small E2E that switches to EN and asserts a translated string (today the
+  EN path is covered only by the parity + ICU checks above).
+- next-intl strict message-key typing (autocomplete + compile-time error on
+  unknown keys).

+# Plano — i18n (infra + extração PT-PT / EN)
+
+> Autor: Opus 4.8 (sessão de design, 2026-05-30). Destinado a implementação pelo Sonnet.
+> Pré-requisitos: MAI CALL v0.1 + Auth v0.2 + v0.3 + verificação E2E, todos implementados. Estado verificado contra o repo.
+> **Motivo:** Pedro quer a app pronta para vários idiomas antes de empilhar mais módulos (o custo de extrair strings cresce com cada módulo). Começar com **PT-PT (default) + EN**. Tradução real só destas duas; a infra fica pronta para adicionar línguas com um ficheiro `.json`.
+
+## Objetivo numa frase
+
+Toda a UI das duas apps passa de **texto fixo em português** para **chaves de tradução** (`t('...')`), com ficheiros `pt.json` + `en.json` por app, e um seletor de idioma — sem mexer nas rotas nem partir os testes E2E.
+
+## Estado atual (medido)
+
+- **148 strings** hardcoded em **23 ficheiros** (59 em operator-pwa, 89 em admin-web). Inventário completo confirmado por levantamento.
+- Inclui strings **dinâmicas** (`Reportado por {email}`, `há {n}m`, `{count} pedidos`) e **datas** via `toLocaleString('pt-PT')` fixo (report-view.tsx).
+- `<html lang>` está **inconsistente**: operator-pwa diz `"en"` (errado, app é PT), admin-web diz `"pt"`. Ambos passam a dinâmicos.
+
+## Decisões fixadas (não revisitar sem motivo forte)
+
+1. **Biblioteca: `next-intl`** (padrão de facto para Next 15 App Router, suporta Server e Client Components, formatação de datas/números/plurais por locale via ICU).
+2. **SEM i18n routing** (modo "without i18n routing" do next-intl). O locale **não** vai no URL (`/en/...`). Vem de um **cookie `NEXT_LOCALE`**. Justificação crítica:
+   - É uma app **interna** (sem SEO) — URLs por locale não trazem valor.
+   - **Não precisa do middleware do next-intl** → **não colide com o middleware de auth** que já existe em ambas as apps. Este é o ponto que torna a integração barata.
+   - Não muda nenhuma rota nem `<Link href>` existente.
+3. **Default = `pt`.** Cookie ausente ou inválido → `pt`. Isto é deliberado e **protege os testes E2E**: os specs procuram texto PT exato; com PT como default, passam sem alteração — **desde que as traduções PT sejam verbatim das strings atuais** (copiar exatamente, incluindo reticências `…`, acentos, e maiúsculas).
+4. **Mensagens por-app**, não um package partilhado. Cada app tem `messages/pt.json` + `messages/en.json` com namespaces internos. Só ~9 strings se repetem entre apps (estados, turnos, "Entrar") — não justifica um `@repo/i18n` partilhado e a complexidade de monorepo que traz. (Extrair um `common` partilhado fica para quando houver um 3º consumidor.)
+5. **Datas/números/tempos relativos** passam a usar o **formatter do next-intl** (`useFormatter`/`getFormatter`), não `toLocaleString('pt-PT')`. O locale do formatter vem do contexto → datas ficam localizadas automaticamente.
+6. **Persistência do locale: só cookie (+ seletor) nesta fase.** Guardar a preferência por-tenant ou por-utilizador na BD fica para depois (corte consciente — ver §Cortes). O cookie não fecha essa porta.
+
+## Estrutura de ficheiros (por app, exemplo admin-web)
+
+```
+apps/admin-web/
+  i18n/
+    request.ts          # getRequestConfig — lê o cookie, carrega as mensagens
+    locales.ts          # LOCALES = ['pt','en'] as const, DEFAULT_LOCALE='pt', labels
+  messages/
+    pt.json
+    en.json
+  app/
+    layout.tsx          # <html lang={locale}>, NextIntlClientProvider (via Providers)
+    language-switcher.tsx  # client component: PT | EN → set cookie + router.refresh()
+  next.config.ts        # withNextIntl(...) composto com o config existente
+```
+
+Namespaces sugeridos (chaves dentro do JSON), para manter organizado:
+- `common` — botões/labels repetidos: `enter`, `cancel`, `confirm`, `back`, `loading`, `close`, estados `status.open/claimed/resolved`.
+- `auth` — login/picker.
+- `home` — home do operador.
+- `maintenance` — fila + criar pedido.
+- `report` — relatório de turno.
+- `errors` — 404/500/genéricos.
+
+## Abordagem técnica (exemplos — implementar exatamente neste padrão)
+
+### `i18n/locales.ts`
+```ts
+export const LOCALES = ['pt', 'en'] as const;
+export type Locale = (typeof LOCALES)[number];
+export const DEFAULT_LOCALE: Locale = 'pt';
+export const LOCALE_LABELS: Record<Locale, string> = { pt: 'PT', en: 'EN' };
+export function isLocale(v: string | undefined): v is Locale {
+  return !!v && (LOCALES as readonly string[]).includes(v);
+}
+```
+
+### `i18n/request.ts` (next-intl, sem routing)
+```ts
+import { getRequestConfig } from 'next-intl/server';
+import { cookies } from 'next/headers';
+import { DEFAULT_LOCALE, isLocale } from './locales';
+
+export default getRequestConfig(async () => {
+  const cookie = (await cookies()).get('NEXT_LOCALE')?.value;
+  const locale = isLocale(cookie) ? cookie : DEFAULT_LOCALE;
+  return {
+    locale,
+    messages: (await import(`../messages/${locale}.json`)).default,
+  };
+});
+```
+
+### `next.config.ts`
+```ts
+import createNextIntlPlugin from 'next-intl/plugin';
+const withNextIntl = createNextIntlPlugin('./i18n/request.ts');
+// admin-web:  export default withNextIntl(nextConfig);
+// operator-pwa: export default withPWA(withNextIntl(nextConfig));  // compor com o PWA
+```
+
+### `app/layout.tsx`
+```tsx
+import { NextIntlClientProvider } from 'next-intl';
+import { getLocale, getMessages } from 'next-intl/server';
+
+export default async function RootLayout({ children }) {
+  const locale = await getLocale();
+  const messages = await getMessages();
+  return (
+    <html lang={locale}>
+      <body>
+        <NextIntlClientProvider locale={locale} messages={messages}>
+          <Providers>{children}</Providers>
+        </NextIntlClientProvider>
+      </body>
+    </html>
+  );
+}
+```
+> Nota: o `NextIntlClientProvider` envolve os `Providers` existentes (client). As mensagens são passadas do server → client uma vez.
+
+### Uso nos componentes
+- **Client component:** `const t = useTranslations('report'); ... t('print')`.
+- **Server component:** `const t = await getTranslations('home');`.
+- **Datas/tempos:** `const format = useFormatter(); format.dateTime(d, {day:'2-digit', month:'2-digit', hour:'2-digit', minute:'2-digit'})` e `format.relativeTime(date)` para os "há 5m". Remove o `'pt-PT'` fixo.
+- **Plurais** (`{count} pedido(s)`): ICU no JSON →
+  `"pendingCount": "{count, plural, one {# pedido por enviar} other {# pedidos por enviar}}"` (pt) / `one {# request pending} other {# requests pending}` (en).
+
+### `language-switcher.tsx` (client)
+```tsx
+'use client';
+// dois botões PT | EN. onClick:
+//   document.cookie = `NEXT_LOCALE=${l}; path=/; max-age=31536000`;
+//   router.refresh();   // re-render server components com o novo locale
+```
+Colocar: na home do operador (`app/page.tsx` header) e no header da fila (`maintenance-queue.tsx`).
+
+## `lib/shifts.ts` — caso especial
+
+Os labels `Manhã/Tarde/Noite` estão numa constante de lógica, não num componente. **Não traduzir no shifts.ts.** Em vez disso, manter as `ShiftKey` (`manha/tarde/noite`) e traduzir no componente: `t('report.shift.' + key)`. O `shifts.ts` perde o campo `label` (ou mantém-no só como fallback técnico não usado na UI).
+
+## Passos de implementação (ordenados)
+
+### Passo 1 — admin-web completo (infra + extração + seletor)
+**Faz:** toda a infra (§Estrutura + §Abordagem) na admin-web; extrai as **89 strings** para `messages/pt.json` (verbatim) + traduz para `messages/en.json`; datas do report via formatter; `<html lang>` dinâmico; seletor de idioma no header da fila; trata os plurais e o `shifts.ts`.
+**AC:**
+- App arranca; com cookie ausente está 100% em PT, **idêntica ao atual** (texto verbatim).
+- Seletor → EN traduz toda a UI da admin-web; volta a PT sem recarregar manualmente.
+- `pnpm test:e2e` (a parte da admin: report + queue) **continua verde sem alterar os specs** (porque PT é default e verbatim).
+- `cd apps/admin-web && npx tsc --noEmit` limpo.
+
+### Passo 2 — operator-pwa completo
+**Faz:** mesma infra (atenção: **compor `withNextIntl` com `withPWA`** no next.config); extrai as **59 strings**; trata `timeAgo`/`sync-chip`/`status-badge` (plurais ICU); corrige `<html lang="en">` → dinâmico; seletor de idioma na home (ou no picker).
+**AC:**
+- operator-pwa 100% PT (verbatim) + EN.
+- `pnpm test:e2e` happy-path **verde sem alterar specs**; `pnpm test:e2e:auth` (login operador usa "Entrar", "PIN incorreto…") **verde** — confirmar que essas strings PT estão verbatim.
+- typecheck limpo. O Service Worker (PWA) continua a funcionar (o config compõe, não substitui).
+
+### Passo 3 — Limpeza, cortes e verificação final
+**Faz:** documentar os cortes (abaixo); README ganha uma secção curta "Idiomas" (como mudar, como adicionar uma língua = novo `.json`); correr a bateria toda.
+**AC:** `pnpm typecheck` (sem novos erros além do pré-existente em @repo/storage), `pnpm test:e2e` (3/3) e `pnpm test:e2e:auth` (4/4) verdes. README documenta adicionar um idioma.
+
+## Cortes propositados — o que NÃO entra
+
+| Cortado | Porquê | Quando volta |
+|---|---|---|
+| Persistir locale por-tenant/utilizador na BD | Cookie + seletor chega para PT/EN; não fecha a porta | quando um cliente pedir locale fixo por fábrica |
+| Traduzir mensagens de erro do tRPC (backend) | Quase nunca chegam ao utilizador (a UI tem mensagens próprias); 1 só está em PT | se passarem a ser mostradas ao utilizador |
+| Strings do `Credentials` provider em `lib/auth.ts` (`name`/`label`) | São do fluxo interno do Auth.js; usamos UI própria (picker/form), nunca se veem | se usarmos a UI default do Auth.js |
+| `pages/_error.tsx` (Pages Router legacy) | Fallback que praticamente não dispara no App Router | se virar relevante |
+| Conteúdo dinâmico (nomes de postos, áreas, descrições) | São dados do cliente, ficam na língua dele — não é tradução | nunca (por design) |
+| Línguas além de PT/EN, RTL | Fora de âmbito agora | quando houver cliente que peça |
+
+## Sequência crítica e riscos
+
+- **Fazer a admin-web inteira primeiro (Passo 1)** valida a abordagem numa app sem PWA antes de a replicar. Só depois o operator-pwa (Passo 2), que tem o wrapper do PWA a compor.
+- **Risco principal — partir os E2E.** Os specs procuram texto PT exato. Mitigação tripla: (a) PT é o default; (b) as traduções PT são **verbatim** (copiar, não reescrever); (c) correr ambos os E2E no fim de cada passo.
+- **Risco — compor `withNextIntl` com `withPWA`** no operator. Mitigação: `withPWA(withNextIntl(nextConfig))`; testar que o SW ainda gera e que a app arranca.
+- **Risco — Server vs Client.** `useTranslations` só em client components; `getTranslations` em server. O inventário marca quais são quais; em caso de dúvida, o componente que já usa `'use client'` usa o hook.
+- Nada disto toca em lógica de negócio, API, ou base de dados → o risco é de UI/config, apanhável pelos E2E.
