## Crítico — Funcionalidades Quebradas
### Auth: Email e Reset de Senha
Todos os três handlers abaixo retornam `200 OK` sem executar nenhuma lógica real.
Dependem de infraestrutura compartilhada que ainda não existe (ver "Bloqueadores").
- [ ] **`forgot_password_handler`** (`src/adapters/inbound/auth_handler.rs:131`)
- Gerar token de reset seguro (UUID v4 ou CSPRNG)
- Salvar na tabela `password_reset_tokens` (ver migration abaixo)
- Enviar email com link de reset via serviço de email
- Token deve ter TTL de 1h e ser invalidado após uso
- [ ] **`verify_email_handler`** (`src/adapters/inbound/auth_handler.rs:138`)
- Validar token recebido contra tabela `email_verification_tokens`
- Chamar `user_repo.verify_email(user_id)` (método já implementado no repo)
- Marcar token como usado / deletar após validação
- Retornar `400 Bad Request` para token inválido ou expirado
- [ ] **`reset_password_handler`** (`src/adapters/inbound/auth_handler.rs:143`)
- Validar token recebido contra tabela `password_reset_tokens`
- Verificar TTL e se já foi usado
- Hash da nova senha com Argon2id
- Atualizar `password_hash` via `user_repo.update()`
- Invalidar token após uso
### Bloqueadores das features de Auth acima
- [ ] **Migration: `password_reset_tokens`**
```sql
CREATE TABLE password_reset_tokens (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
token TEXT NOT NULL UNIQUE,
used_at TIMESTAMPTZ,
expires_at TIMESTAMPTZ NOT NULL,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
);
CREATE INDEX ON password_reset_tokens (token);
```
- [ ] **Migration: `email_verification_tokens`**
```sql
CREATE TABLE email_verification_tokens (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
token TEXT NOT NULL UNIQUE,
used_at TIMESTAMPTZ,
expires_at TIMESTAMPTZ NOT NULL,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
);
CREATE INDEX ON email_verification_tokens (token);
```
- [ ] **Serviço de email** (`src/infrastructure/email_service.rs` — novo arquivo)
- Adicionar dependência: `lettre` (SMTP) ou integração com API (Resend, SendGrid, Mailgun)
- Adicionar vars de ambiente no `config.rs`: `SMTP_HOST`, `SMTP_PORT`, `SMTP_USER`, `SMTP_PASS`, `EMAIL_FROM`
- Implementar `send_password_reset_email(to, reset_link)`
- Implementar `send_verification_email(to, code)`
### Perfil de Usuário
- [ ] **`update_me_handler`** (`src/adapters/inbound/user_handler.rs:64`)
- Handler valida formato de email mas não persiste nada
- Implementar chamada a `user_repo.update()` com os campos recebidos
- Considerar campos permitidos: `name` (se adicionado ao domínio), `email`
- Revalidar unicidade de email antes de atualizar
---
## Médio — Segurança
- [ ] **Google OAuth: validar `aud` claim** (`src/adapters/inbound/auth_handler.rs:159`)
- O parâmetro `_client_id` é recebido mas ignorado
- Após obter o payload do tokeninfo do Google, verificar que `aud == GOOGLE_CLIENT_ID`
- Rejeitar com `401 Unauthorized` se o `aud` não corresponder
- Sem isso, qualquer Google token válido de qualquer app é aceito
- [ ] **Logout: invalidar refresh token** (`src/adapters/inbound/auth_handler.rs:121`)
- Atualmente retorna `204 No Content` sem nenhuma ação
- Opção A (simples): tabela `revoked_tokens` no PostgreSQL com TTL via `expires_at`
- Opção B (recomendada): Redis com `SET revoked:{jti} 1 EX <ttl>`
- Middleware de auth deve checar blocklist ao validar tokens
- Adicionar campo `jti` (JWT ID) aos tokens para identificação única
---
## Baixo — Qualidade e Completude
- [ ] **Sort de filamentos não aplicado** (`src/adapters/outbound/postgres_filament_repo.rs`)
- `SortOrder` enum está definido em `ports/filament_repository.rs`
- SQL em `list()` sempre usa `ORDER BY created_at DESC`, ignorando o campo `sort`
- `filament_handler.rs:203` tem `// TODO: parse sort string para SortOrder` — completar o parse
- Aplicar o `SortOrder` no SQL com match: `net_weight_g ASC`, `net_weight_g DESC`, `created_at DESC`
- [ ] **Paginação: retornar total de itens**
- `FilamentRepository::count()` está implementado no repo mas nunca é chamado
- `list_filaments_handler` não retorna metadados de paginação
- Adicionar ao response: `{ data: [...], total: N, page: N, per_page: N }`
- Chamar `repo.count(user_id, filter)` em paralelo com `repo.list()`
- [ ] **`GET /spool-presets/:id` — handler ausente**
- Rota está registrada no `router.rs`
- Nenhum handler correspondente existe em `spool_preset_handler.rs`
- Implementar `get_preset_handler` ou remover a rota do router
- [ ] **Testes**
- Sem nenhum teste unitário ou de integração no projeto
- Prioridade: `AuthService` (hash, JWT), `FilamentService` (cálculos de peso, conflito offline), handlers de auth
- Usar `sqlx::test` para testes de repositório com banco real em transação

### Etiqueta PDF (`GET /filaments/:id/label.pdf`)

- Retorna PDF de página única com dimensões exatas em mm — ideal para impressoras de etiqueta (Brother, Dymo)

- `Content-Type: application/pdf`
- `Content-Disposition: attachment; filename="meowspool-label-{id}.pdf"`
### Parâmetro `fields` (SVG e PDF)
Controla quais elementos aparecem na etiqueta. Valor: string com itens separados por vírgula.
| Valor | Elemento |
| --------------- | ------------------------------- |
| `color` | Barra de cor lateral |
| `name` | Nome do modelo |
| `material_brand`| Texto "Marca · Material" |

| `print_temp` | Temperatura de impressão |
| `qrcode` | QR Code com deep link |
Se `fields` for omitido, todos os elementos são incluídos.
Implementado em `LabelFields` (`filament_service.rs`) — `LabelFields::from_str(Option<&str>)`.

## Mudanças Recentes (14/03/2026)
### ✅ Exportação de Etiqueta PDF (`GET /filaments/:id/label.pdf`)
- **Dependência**: `printpdf = "0.7"` adicionada ao `Cargo.toml`
- **Service**: `FilamentService::generate_label_pdf` em `filament_service.rs`
- Layout: fundo `#1E1B18`, barra de cor (filament.color_hex), texto Helvetica builtin, QR Code PNG luma embutido
- Página com dimensões exatas em mm via `printpdf::Mm`
- Usa `Polygon` + `PaintMode::Fill` para retângulos (API do printpdf 0.7)
- QR Code embutido via `ImageXObject` com pixels luma brutos — sem depender do feature `image` do printpdf
- **Handler**: `export_label_pdf_handler` em `filament_handler.rs`
- **Rota**: `GET /api/v1/filaments/:id/label.pdf`
### ✅ Controle de Campos na Etiqueta (`fields` query param)
- **Struct**: `LabelFields` em `filament_service.rs` — parseia string CSV de campos ativos
- **Aplicado em**: `generate_label_svg` e `generate_label_pdf`
- **LabelQuery**: adicionado campo `fields: Option<String>` em `filament_handler.rs`
- Permite que o cliente selecione quais elementos aparecem na etiqueta (cor, nome, material, peso, temp, QR)
### ✅ Correção: PUT Spool Preset retornava FORBIDDEN
**Local:** `src/adapters/outbound/postgres_spool_preset_repo.rs` — método `update()`
