MAI CALL - auth v0.2

# O que mudou
1 Schema: failedAttempts + lockedUntil em User; migration auth_v0_2_lockout aplicada; crypto.ts com hashSecret/verifySecret (Node scrypt nativo, zero deps)
2 packages/api/src/auth.ts — authenticateCredential com lockout de 5 tentativas
3 Seed reescrito: admin hashed admin1234, operadores hashed 1111/2222/3333
4 Porta das traseiras fechada: AUTH_DEV_AUTOLOGIN ignorado quando NODE_ENV=production, em ambas as apps
5 operator-pwa: Credentials provider usa PIN + allowedRoles:['OPERATOR']; cookies fieldops-op.*
6 Picker em 2 estados: lista → teclado PIN (botões grandes, dots de progresso, mensagem de erro sem dar pistas)
7 admin-web: Auth.js completo (auth.config, auth.ts, route handler, middleware, /login page, AUTH_SECRET no env) com cookies fieldops-admin.*
8 scripts/auth-smoke.ts (11/11 ✓); .env.example e README atualizados

+# Plano — Auth real v0.2 (pré-piloto)
+
+> Autor: Opus 4.8 (sessão de design, 2026-05-30). Destinado a implementação pelo Sonnet.
+> Pré-requisito: MAI CALL v0.1 completo (ver [`mai-call-v0.1.md`](./mai-call-v0.1.md)). Estado do código no momento do design verificado contra o repo.
+
+## Objetivo numa frase
+
+Fechar a porta das traseiras (`AUTH_DEV_AUTOLOGIN`) e dar a cada tipo de utilizador o login certo:
+**admin/supervisor → email + password**; **operador → escolha na lista + PIN de 4–6 dígitos**.
+Tudo o resto do produto (MAI CALL) continua a funcionar igual.
+
+## Decisões fixadas (não revisitar sem motivo forte)
+
+1. **Um único segredo por utilizador, guardado em `User.passwordHash`** (já existe, nullable). Password (admin) e PIN (operador) são ambos "um segredo que o utilizador prova" — mesmo campo, mesma função de hash. O `role` decide qual UI/validação se aplica.
+2. **Hashing com `crypto.scrypt` nativo do Node 22** — zero dependências, sem build nativo (evita atrito no Windows + pnpm 11 que bloqueia postinstall). NÃO instalar bcrypt/argon nativos.
+3. **`AUTH_DEV_AUTOLOGIN` não desaparece — passa a ser ignorado quando `NODE_ENV === 'production'`.** Em dev/test continua a funcionar (conveniência local + E2E). A porta das traseiras fica fechada **no código**, não só por honestidade do `.env`.
+4. **Operador entra por lista + PIN** (não password). O picker que já existe ganha um segundo passo (teclado de PIN). Isto mantém o caminho para o RFID limpo: trocar o teclado por um leitor de cartão, sem mexer no resto.
+5. **Admin-web ganha Auth.js a sério** (hoje não tem nenhum). Mesmo padrão da operator-pwa: Credentials provider + JWT + middleware + página de login.
+6. **Lockout mínimo** (5 tentativas falhadas → bloqueio de 5 min) porque um PIN numérico exposto na rede sem qualquer travão a força-bruta é irresponsável para um piloto. É a única adição de schema.
+7. **Continua single-tenant na prática.** O login procura o utilizador por email com `findFirst` (o email só é único *por tenant*, `@@unique([tenantId, email])`). Para o piloto (uma fábrica = um tenant) é suficiente. Multi-tenant login (selector de tenant ou email globalmente único) fica para quando entrar o 2º cliente.
+
+---
+
+## 1. Modelo de dados
+
+Sem modelos novos. Só **dois campos** em `User`, para o lockout:
+
+```prisma
+model User {
+  // ... campos existentes (id, tenantId, email, passwordHash, role, createdAt, relations) ...
+
+  failedAttempts Int       @default(0)
+  lockedUntil    DateTime?
+}
+```
+
+`passwordHash` já existe e é `String?` — passa a ser efetivamente usado. **Não** mudar o tipo nem a nulidade (um utilizador sem segredo definido simplesmente não consegue entrar — `verifySecret` devolve `false`).
+
+`tenant-extension.ts` não precisa de alteração (`User` já está em `TENANT_SCOPED_MODELS`), mas atenção: o login corre **antes** de haver tenant, por isso usa o `prisma` não-scoped (ver §3).
+
+**Migration:** após editar o schema, correr `pnpm db:migrate` (nome sugerido: `auth_v0_2_lockout`).
+
+---
+
+## 2. Função de hashing — `@repo/db`
+
+Cria-se `packages/db/src/crypto.ts` e exporta-se de `packages/db/src/index.ts`.
+Fica em `@repo/db` (e não em `@repo/api`) **de propósito**: o `seed.ts` vive em `packages/db` e precisa de `hashSecret`; como `api` depende de `db` (e não o contrário), só `db` pode ser importado por todos sem ciclo.
+
+```ts
+// packages/db/src/crypto.ts
+import { randomBytes, scrypt as _scrypt, timingSafeEqual } from 'node:crypto';
+import { promisify } from 'node:util';
+
+const scrypt = promisify(_scrypt);
+const KEYLEN = 64;
+
+/** Devolve "scrypt$<saltHex>$<hashHex>". Serve para password (admin) e PIN (operador). */
+export async function hashSecret(plain: string): Promise<string> {
+  const salt = randomBytes(16);
+  const derived = (await scrypt(plain, salt, KEYLEN)) as Buffer;
+  return `scrypt$${salt.toString('hex')}$${derived.toString('hex')}`;
+}
+
+/** Verificação em tempo constante. `stored` null/malformado → false (nunca lança). */
+export async function verifySecret(plain: string, stored: string | null): Promise<boolean> {
+  if (!stored) return false;
+  const [scheme, saltHex, hashHex] = stored.split('$');
+  if (scheme !== 'scrypt' || !saltHex || !hashHex) return false;
+  const salt = Buffer.from(saltHex, 'hex');
+  const expected = Buffer.from(hashHex, 'hex');
+  const derived = (await scrypt(plain, salt, expected.length)) as Buffer;
+  return derived.length === expected.length && timingSafeEqual(derived, expected);
+}
+```
+
+Export em `packages/db/src/index.ts`: `export { hashSecret, verifySecret } from './crypto';`
+
+---
+
+## 3. Verificação de credenciais — `@repo/api`
+
+Lógica única partilhada pelas duas apps (lookup + verify + lockout). Vai em `@repo/api` porque toca Prisma + regra de negócio, e ambas as apps já dependem de `@repo/api`.
+
+```ts
+// packages/api/src/auth.ts
+import { prisma, verifySecret } from '@repo/db';
+import type { SessionUser } from './context';
+
+const MAX_ATTEMPTS = 5;
+const LOCK_MS = 5 * 60_000;
+
+/**
+ * Autentica por email + segredo (PIN ou password), restringindo a roles permitidos.
+ * Usa o prisma NÃO-scoped: o login acontece antes de existir tenant.
+ * Devolve o SessionUser em sucesso, null em qualquer falha (credenciais, role, lockout).
+ */
+export async function authenticateCredential(opts: {
+  email: string;
+  secret: string;
+  allowedRoles: SessionUser['role'][];
+}): Promise<SessionUser | null> {
+  const user = await prisma.user.findFirst({ where: { email: opts.email } });
+  if (!user) return null;
+  if (!opts.allowedRoles.includes(user.role)) return null;
+  if (user.lockedUntil && user.lockedUntil > new Date()) return null;
+
+  const ok = await verifySecret(opts.secret, user.passwordHash);
+  if (!ok) {
+    const attempts = user.failedAttempts + 1;
+    await prisma.user.update({
+      where: { id: user.id },
+      data: {
+        failedAttempts: attempts,
+        lockedUntil: attempts >= MAX_ATTEMPTS ? new Date(Date.now() + LOCK_MS) : null,
+      },
+    });
+    return null;
+  }
+
+  if (user.failedAttempts !== 0 || user.lockedUntil) {
+    await prisma.user.update({
+      where: { id: user.id },
+      data: { failedAttempts: 0, lockedUntil: null },
+    });
+  }
+
+  return { id: user.id, email: user.email, role: user.role, tenantId: user.tenantId };
+}
+```
+
+Export em `packages/api/src/index.ts`: `export { authenticateCredential } from './auth';`
+(`SessionUser` já é exportado de `@repo/api` — confirmado em `context.ts`.)
+
+---
+
+## 4. Fechar a porta das traseiras (`NODE_ENV` gating)
+
+A regra única: **autologin só é honrado se `AUTH_DEV_AUTOLOGIN` E `NODE_ENV !== 'production'`.**
+
+**operator-pwa** — `apps/operator-pwa/lib/auth.ts`, em `resolveUser()`:
+```ts
+const autologinAllowed = env.AUTH_DEV_AUTOLOGIN && process.env.NODE_ENV !== 'production';
+if (autologinAllowed) {
+  // ... fallback admin@demo.local (igual ao atual)
+}
+```
+
+**operator-pwa** — `apps/operator-pwa/middleware.ts`:
+```ts
+const isAutologin =
+  process.env['AUTH_DEV_AUTOLOGIN'] === 'true' && process.env.NODE_ENV !== 'production';
+```
+O redirect passa a apontar para `/select-operator` na operator-pwa (já aponta) — sem mudança de destino.
+
+**admin-web** — passa a ter `resolveUser()` real (ver §6), com o mesmo gating no fallback.
+
+> **Porque é que isto não parte o E2E:** o Playwright corre `next dev` (logo `NODE_ENV === 'development'`) e injecta `AUTH_DEV_AUTOLOGIN=true` nos webServers. O gating só desliga o autologin em `production`. O happy-path continua a entrar por autologin sem mexer no teste.
+
+---
+
+## 5. operator-pwa — login do operador (lista + PIN)
+
+### 5a. Credentials provider (`apps/operator-pwa/lib/auth.ts`)
+
+Substituir o provider placeholder (que aceitava email sem password) por:
+
+```ts
+Credentials({
+  name: 'Operador (PIN)',
+  credentials: { email: { type: 'text' }, pin: { type: 'password' } },
+  async authorize(credentials) {
+    const email = credentials?.email;
+    const pin = credentials?.pin;
+    if (typeof email !== 'string' || typeof pin !== 'string') return null;
+    const u = await authenticateCredential({ email, secret: pin, allowedRoles: ['OPERATOR'] });
+    if (!u) return null;
+    return { id: u.id, email: u.email, name: u.email, role: u.role, tenantId: u.tenantId };
+  },
+}),
+```
+`allowedRoles: ['OPERATOR']` garante que admins não entram pela app do operador.
+
+### 5b. Cookie name distinto (evita colisão com admin-web)
+
+Em `apps/operator-pwa/lib/auth.config.ts`, dentro do objeto `authConfig`, acrescentar:
+```ts
+cookies: {
+  sessionToken: { name: 'fieldops-op.session-token' },
+  callbackUrl:  { name: 'fieldops-op.callback-url' },
+  csrfToken:    { name: 'fieldops-op.csrf-token' },
+},
+```
+> **Porquê:** cookies não são isolados por porto. Sem nomes distintos, abrir admin-web (:3001) e operator-pwa (:3000) na mesma máquina sobrepõe a sessão. Cada app tem de ter o seu prefixo.
+
+### 5c. Ecrã de PIN
+
+`/select-operator` mantém-se como entrada, mas o `OperatorPicker` ganha **dois estados**:
+
+1. **Lista** (como hoje): mostra operadores; tap selecciona em vez de fazer `signIn` imediato.
+2. **Teclado de PIN**: depois de escolher, mostra o nome do operador + um teclado numérico (botões 0–9, apagar) + indicador de dígitos. Ao atingir o comprimento (aceitar 4 a 6 dígitos; submeter no botão "Entrar") chama:
+   ```ts
+   const result = await signIn('credentials', { email, pin, redirect: false });
+   ```
+   - sucesso (`!result?.error`): `router.push('/'); router.refresh();`
+   - erro: limpar dígitos e mostrar **"PIN incorreto ou conta bloqueada. Tente novamente."** (não distinguir os dois casos — não dar pistas a quem ataca).
+   - botão "Voltar" regressa à lista.
+
+Mobile-first, botões grandes (target dedo com luva). Reaproveitar as classes Tailwind já usadas no picker atual.
+
+`apps/operator-pwa/app/select-operator/page.tsx` não muda a query (continua a listar operadores via `prisma` direto). Só passa a precisar do `id`+`email` (já passa).
+
+`sign-out-button.tsx` (botão "Trocar") não muda — `signOut({ callbackUrl: '/select-operator' })` continua correto.
+
+---
+
+## 6. admin-web — login do admin (email + password)
+
+A admin-web **não tem Auth.js**. Adiciona-se o stack completo, espelhando a operator-pwa.
+
+### 6a. Dependência
+
+Em `apps/admin-web/package.json`, acrescentar a `dependencies` (mesma versão exata da operator-pwa, para não haver drift):
+```json
+"next-auth": "5.0.0-beta.25"
+```
+Correr `pnpm install`.
+
+### 6b. Ficheiros novos
+
+- **`apps/admin-web/lib/auth.config.ts`** — cópia do edge-safe config da operator-pwa, com:
+  - `pages: { signIn: '/login' }`
+  - os mesmos callbacks `jwt`/`session` (copiar tal e qual).
+  - `cookies` com prefixo **`fieldops-admin.`** (sessionToken / callbackUrl / csrfToken) — ver §5b.
+
+- **`apps/admin-web/lib/auth.ts`** — substitui o `resolveUser` placeholder atual. Estrutura igual à operator-pwa:
+  ```ts
+  export const { handlers, auth, signIn, signOut } = NextAuth({
+    ...authConfig,
+    secret: env.AUTH_SECRET,
+    providers: [
+      Credentials({
+        name: 'Email + password',
+        credentials: { email: { type: 'email' }, password: { type: 'password' } },
+        async authorize(c) {
+          if (typeof c?.email !== 'string' || typeof c?.password !== 'string') return null;
+          const u = await authenticateCredential({
+            email: c.email, secret: c.password, allowedRoles: ['ADMIN', 'SUPERVISOR'],
+          });
+          if (!u) return null;
+          return { id: u.id, email: u.email, name: u.email, role: u.role, tenantId: u.tenantId };
+        },
+      }),
+    ],
+  });
+
+  export async function resolveUser(): Promise<SessionUser | null> {
+    const session = await auth();
+    const u = session?.user as any;
+    if (u?.id && u?.tenantId) return { id: u.id, email: u.email, role: u.role, tenantId: u.tenantId };
+
+    const autologinAllowed =
+      process.env['AUTH_DEV_AUTOLOGIN'] === 'true' && process.env.NODE_ENV !== 'production';
+    if (autologinAllowed) {
+      const admin = await prisma.user.findFirst({ where: { email: 'admin@demo.local' } });
+      if (admin) return { id: admin.id, email: admin.email, role: admin.role as any, tenantId: admin.tenantId };
+    }
+    return null;
+  }
+  ```
+
+- **`apps/admin-web/app/api/auth/[...nextauth]/route.ts`** — idêntico ao da operator-pwa:
+  ```ts
+  import { handlers } from '@/lib/auth';
+  export const { GET, POST } = handlers;
+  export const runtime = 'nodejs';
+  ```
+
+- **`apps/admin-web/middleware.ts`** — espelha o da operator-pwa, mas redireciona para `/login`:
+  ```ts
+  import NextAuth from 'next-auth';
+  import { authConfig } from './lib/auth.config';
+  const { auth } = NextAuth(authConfig);
+  export default auth((req) => {
+    const isLoggedIn = !!req.auth?.user;
+    const isAutologin =
+      process.env['AUTH_DEV_AUTOLOGIN'] === 'true' && process.env.NODE_ENV !== 'production';
+    const { pathname } = req.nextUrl;
+    if (pathname === '/login') {
+      if (isLoggedIn) return Response.redirect(new URL('/maintenance', req.url));
+      return;
+    }
+    if (!isLoggedIn && !isAutologin) return Response.redirect(new URL('/login', req.url));
+  });
+  export const config = {
+    matcher: ['/((?!api/auth|api/trpc|_next/static|_next/image|favicon.ico).*)'],
+  };
+  ```
+
+- **`apps/admin-web/app/login/page.tsx`** + **`login-form.tsx`** (client component):
+  - form com email + password, botão "Entrar".
+  - `const result = await signIn('credentials', { email, password, redirect: false });`
+  - sucesso → `router.push('/maintenance')`; erro → "Email ou password incorretos. Tente novamente."
+  - Estilo: reaproveitar componentes `@repo/ui` (Card/Button) já usados na queue.
+
+> `signIn`/`signOut` de `next-auth/react` funcionam **sem** `SessionProvider`, por isso `apps/admin-web/app/providers.tsx` não precisa de mudar.
+
+### 6c. env da admin-web
+
+`apps/admin-web/env.ts` — acrescentar ao bloco `server` (hoje só tem `DATABASE_URL`, `AUTH_DEV_AUTOLOGIN`, `LOG_LEVEL`):
+```ts
+AUTH_SECRET: z.string().min(1, 'AUTH_SECRET is required'),
+```
+e no `runtimeEnv`: `AUTH_SECRET: process.env.AUTH_SECRET,`
+**Não** adicionar `AUTH_URL`: o `.env` partilhado tem `AUTH_URL=http://localhost:3000` (da operator-pwa) e isso seria errado para a admin. Com `trustHost: true` (já no authConfig), o Auth.js infere o host a partir do request — não precisa de `AUTH_URL` em dev.
+
+---
+
+## 7. Seed — definir PINs e password demo
+
+`packages/db/prisma/seed.ts`:
+
+- importar `hashSecret` de `@repo/db` (ou diretamente de `./crypto` — mas o seed já importa `@prisma/client` dinamicamente; usar import estático de `../src/crypto.js`/`@repo/db` conforme o que o build resolver; preferir `@repo/db`).
+- admin: `passwordHash: await hashSecret(DEMO_ADMIN_PASSWORD)`.
+- cada operador: `passwordHash: await hashSecret(pin)` com PINs distintos. Como `createMany` não permite valores assíncronos por linha de forma limpa, trocar o `createMany` dos operadores por um loop `for ... create`.
+- constantes no topo:
+  ```ts
+  const DEMO_ADMIN_PASSWORD = 'admin1234';
+  const OPERATORS = [
+    { email: 'op1@demo.local', pin: '1111' },
+    { email: 'op2@demo.local', pin: '2222' },
+    { email: 'op3@demo.local', pin: '3333' },
+  ];
+  ```
+- imprimir as credenciais demo no final (`console.warn`) para Pedro saber o que digitar:
+  ```
+  Seed: admin=admin@demo.local / admin1234 | operadores: op1=1111 op2=2222 op3=3333
+  ```
+
+`failedAttempts`/`lockedUntil` ficam nos defaults (0/null), não precisam de set no seed.
+
+---
+
+## 8. `.env.example` + README
+
+- **`.env.example`**: na nota do `AUTH_DEV_AUTOLOGIN`, acrescentar que **mesmo a `true` é ignorado em produção** (`NODE_ENV=production`). Manter default `"false"`.
+- **README** — secção "Known limitations": remover/atualizar a linha "No real authentication" (agora há), e a linha "Operator picker, not TAG/card" mantém-se mas passa a "picker + PIN". Acrescentar as credenciais demo ao "Demo flow" (admin: `admin@demo.local`/`admin1234`; operadores: PINs). Atualizar o aviso da porta das traseiras para refletir o gating por `NODE_ENV`.
+
+---
+
+## 9. Verificação — smoke script (segue o padrão do repo)
+
+Criar `scripts/auth-smoke.ts` (como os outros `scripts/*-smoke.ts`):
+
+1. corre contra a BD seeded.
+2. `authenticateCredential({ email:'op1@demo.local', secret:'1111', allowedRoles:['OPERATOR'] })` → devolve user. ✓
+3. PIN errado 5× → 6ª chamada com PIN **certo** devolve `null` (lockout ativo). ✓
+4. role errado: `authenticateCredential({ email:'admin@demo.local', secret:'admin1234', allowedRoles:['OPERATOR'] })` → `null`. ✓
+5. admin com password certa e `allowedRoles:['ADMIN','SUPERVISOR']` → user. ✓
+6. no fim, repor `failedAttempts=0, lockedUntil=null` do op1 para não deixar a BD num estado bloqueado (ou re-seed).
+
+Adicionar ao README a linha `pnpm tsx scripts/auth-smoke.ts`.
+
+O E2E `mai-call.spec.ts` **não muda** (continua via autologin em dev, §4).
+
+---
+
+## 10. Cortes propositados — o que NÃO entra na v0.2
+
+| Cortado | Porquê | Quando volta |
+|---|---|---|
+| RFID/cartão do operador | PIN é a ponte; arquitetura já preparada | quando MY QUALITY entrar |
+| Reset de password / "esqueci o PIN" self-service | Sem email/SMS infra; admin re-seed ou futura UI | v0.3 |
+| UI de gestão de utilizadores (criar/editar/role) | Cria-se via seed/SQL no piloto | com onboarding multi-tenant |
+| Selector de tenant no login | Single-tenant no piloto; email `findFirst` chega | 2º cliente |
+| SSO / MFA | Não pedido pelo piloto | se cliente exigir |
+| Rate-limit por IP (além do lockout por conta) | Lockout por conta cobre o PIN; IP precisa de infra | se necessário |
+| Rotação de `AUTH_SECRET` / política de sessão curta | Default JWT chega para piloto | endurecimento pós-piloto |
+| Expiração/rotação de PIN | Sem valor demonstrado no piloto | quando pedirem |
+
+---
+
+## 11. Plano de implementação (passos pequenos, ordenados)
+
+Cada passo é mergeable e tem critério de aceitação testável.
+
+### Passo 1 — Schema + crypto util
+**Faz:** §1 (campos `failedAttempts`/`lockedUntil` + migration) e §2 (`packages/db/src/crypto.ts` + export).
+**AC:** `pnpm db:migrate` corre sem erro; um script ad-hoc consegue `hashSecret('1234')` e `verifySecret('1234', hash) === true`, `verifySecret('9999', hash) === false`, `verifySecret('x', null) === false`.
+
+### Passo 2 — `authenticateCredential` em `@repo/api`
+**Faz:** §3 (`packages/api/src/auth.ts` + export).
+**AC:** importável de `@repo/api`; `pnpm typecheck` verde. (Comportamento real testado no Passo 7.)
+
+### Passo 3 — Seed com PINs/password
+**Faz:** §7.
+**AC:** `pnpm db:seed` corre e imprime as credenciais; em Prisma Studio, `passwordHash` dos 4 utilizadores está preenchido (formato `scrypt$...`).
+
+### Passo 4 — Fechar a porta das traseiras
+**Faz:** §4 (gating `NODE_ENV` na operator-pwa: `resolveUser` + `middleware`).
+**AC:** com `AUTH_DEV_AUTOLOGIN=true` e `next dev`, a operator-pwa continua a entrar (dev). Simular produção (`NODE_ENV=production` num build) → abrir `/` redireciona para `/select-operator` em vez de auto-entrar.
+
+### Passo 5 — operator-pwa: provider PIN + cookie name
+**Faz:** §5a + §5b (authorize com PIN + `allowedRoles:['OPERATOR']`; cookies `fieldops-op.*`).
+**AC:** `signIn('credentials',{email:'op1@demo.local',pin:'1111'})` cria sessão; `pin:'0000'` falha. Cookie no browser chama-se `fieldops-op.session-token`.
+
+### Passo 6 — operator-pwa: ecrã de PIN
+**Faz:** §5c (picker em 2 estados: lista → teclado PIN).
+**AC:** Demo: limpar cookies → `/` redireciona ao picker → escolher op1 → teclar `1111` → "Entrar" → home mostra `op1@demo.local`. PIN errado mostra a mensagem e limpa os dígitos.
+
+### Passo 7 — admin-web: Auth.js completo + login
+**Faz:** §6 inteiro (dep, auth.config, auth.ts, route handler, middleware, /login, env `AUTH_SECRET`, cookies `fieldops-admin.*`).
+**AC:** com autologin **off** (ou prod), abrir :3001 redireciona a `/login`; entrar com `admin@demo.local`/`admin1234` chega à fila `/maintenance`; password errada falha; um OPERATOR não consegue entrar na admin-web (role bloqueado).
+
+### Passo 8 — Smoke + docs
+**Faz:** §9 (`scripts/auth-smoke.ts`) + §8 (`.env.example` + README).
+**AC:** `pnpm tsx scripts/auth-smoke.ts` passa todos os casos (incl. lockout às 5 tentativas); `pnpm test:e2e` continua verde; outro dev segue o README e consegue fazer login real nas duas apps.
+
+---
+
+**Sequência crítica:** Passos 1→3 são fundação (schema, crypto, credenciais). Passo 4 fecha o buraco de segurança e pode ir cedo. Passos 5–6 (operador) e 7 (admin) são independentes — podem ir em paralelo se houver 2 devs. Passo 8 fecha.
+
+**Risco principal:** a colisão de cookies entre :3000 e :3001 (§5b/§6b) — se os nomes de cookie não forem distintos, fazer login numa app desloga a outra de forma confusa. Verificar explicitamente os nomes dos cookies no DevTools no Passo 5 e 7.
