# Filament Evolution - Arquitetura do Plugin

Plugin Filament para integração com Evolution API v2 (WhatsApp).

---

## 🏢 Multi-Tenancy

> O plugin suporta **multi-tenancy nativo do Filament v4** através de configuração dinâmica.

### Características

| Feature | Descrição |
|---------|-----------|
| **Habilitação** | Via `config('filament-evolution.tenancy.enabled')` |
| **Coluna Dinâmica** | Configurável: `team_id`, `company_id`, `tenant_id`, etc. |
| **Tipo de Coluna** | Suporta `uuid` ou `id` (bigint) |
| **Scope Automático** | Models aplicam filtro por tenant automaticamente |
| **Auto-fill** | Tenant ID é preenchido automaticamente ao criar registros |

### Configuração Rápida

```env
# .env
EVOLUTION_TENANCY_ENABLED=true
EVOLUTION_TENANT_COLUMN=team_id
EVOLUTION_TENANT_TABLE=teams
EVOLUTION_TENANT_MODEL=App\Models\Team
EVOLUTION_TENANT_COLUMN_TYPE=uuid
```

> 📖 Veja a seção **Models com Multi-Tenancy** para detalhes de implementação.

## 📊 Análise da Estrutura Atual

### ✅ O que você JÁ TEM (e funciona bem):

| Componente | Arquivo | Status |
|------------|---------|--------|
| **Config** | `config/filament-evolution.php` | 🔵 NOVO - Config própria do plugin |
| **Model** | `app/Models/WhatsappInstance.php` | ✅ Com UUID, casts, fillable |
| **Migration** | `create_whatsapp_instances_table.php` | ✅ Campos completos |
| **Enum** | `StatusConnectionEnum.php` | ✅ Com HasLabel, HasColor |
| **HTTP Client** | `EvolutionClientTrait.php` | ✅ Trait reutilizável |
| **Services Instance** | 6 services (Create, Connect, Delete, etc.) | ✅ Funcionais |
| **Services Message** | `SendMessageEvolutionService.php` | ✅ Funcional |
| **Webhook Controller** | `EvolutionWebhookController.php` | ✅ Switch por evento |
| **Filament Resource** | `WhatsappInstanceResource.php` | ✅ Com Form/Table/Infolist separados |
| **Livewire QR Code** | `EvolutionQrCode.php` | ✅ Com polling e countdown |
| **Views** | `evolution-qr-code.blade.php` | ✅ UI completa |

### ❌ O que FALTA (para melhorar qualidade e manutenibilidade):

| Componente | Benefício |
|------------|-----------|
| **DTOs** | Tipagem forte, autocomplete, validação |
| **Events** | Desacoplamento, extensibilidade |
| **Listeners** | Reação a eventos de forma organizada |
| **Jobs** | Processamento em background |
| **Exceptions** | Tratamento de erro consistente |
| **Contracts/Interfaces** | Testabilidade, injeção de dependência |
| **Testes** | Confiabilidade, refatoração segura |

## 🔐 Filosofia de Segurança

### Credenciais vs Dados Operacionais

| Tipo | Onde Armazenar | Exemplo |
|------|----------------|---------|
| **Credenciais** | `.env` / Config | API Key, Webhook Secret, URL do servidor |
| **Dados Operacionais** | Banco de Dados | Nome da instância, status, número conectado |

### Por que essa separação?

1. **Segurança**: Credenciais no `.env` não vazam em backups de banco
2. **Reutilização**: Mesma API Key para múltiplas instâncias
3. **Deploy**: Credenciais diferentes por ambiente (dev/staging/prod)
4. **Compliance**: Facilita auditoria e rotação de chaves

### Fluxo de Autenticação

## 📝 Notas Importantes

1. **Segurança do Webhook**: Sempre validar a origem do webhook usando secret/signature
2. **Rate Limiting**: A Evolution API pode ter limites, implementar retry com backoff
3. **Queue**: Webhooks e envios devem ser processados em background
4. **Soft Deletes**: Instâncias usam soft delete para manter histórico
5. **Multi-tenancy**: ✅ Suporte completo via `config('filament-evolution.tenancy')`
6. **Config Própria**: ✅ Plugin usa `config/filament-evolution.php` (não `services.php`)
