+# Arquitetura Multi-tenant - Modelo de Negócio Aggios
+
+## Visão Geral da Plataforma
+
+A plataforma Aggios utiliza uma arquitetura multi-tenant em três camadas principais:
+
+```
+┌─────────────────────────────────────────────────┐
+│  aggios.app (Site Institucional)                │
+│  - Marketing                                     │

+   Clientes da            Clientes da
+   IdeaPages              Outra Agência
+```
+
+## Como Funciona na Prática
+
+### 1. Sua Agência (Exemplo: IdeaPages)
+- **URL**: `idealpages.aggios.app`
+- **White Label**: Logo e cores da IdeaPages
+- **Clientes**: Cadastrados DENTRO da agência IdeaPages
+- **Isolamento**: Cada cliente é isolado por tenant_id (multi-tenant)
+
+### 2. Quando um Cliente Precisa do CRM
+
+**Você SEMPRE manda a URL da sua agência**, não aggios.app!
+
+- Cliente cria conta em `idealpages.aggios.app`
+- Cliente acessa `idealpages.aggios.app` com login próprio
+- Cliente vê **SEU logo** (IdeaPages)
+- Cliente vê **SEU white label**
+- Cliente só vê os dados DELE (isolamento por tenant)
+
+### 3. Estrutura de Clientes
+
+```
+IdeaPages (você - agência)
+├── Cliente 1 (Empresa ABC)
+│   ├── Vê: Logo IdeaPages
+│   ├── Acessa: idealpages.aggios.app
+│   └── Usa: CRM, ERP, Projetos (dados isolados)
+│
+├── Cliente 2 (Tech Solutions)
+│   ├── Vê: Logo IdeaPages
+│   ├── Acessa: idealpages.aggios.app
+│   └── Usa: CRM, ERP, Projetos (dados isolados)
+│
+└── Cliente 3 (Marketing Pro)
+    ├── Vê: Logo IdeaPages
+    ├── Acessa: idealpages.aggios.app
+    └── Usa: CRM, ERP, Projetos (dados isolados)
+```
+
+## Benefícios para a Agência
+
+✅ **White Label Completo**: Cliente vê sua marca, não "Aggios"
+✅ **Controle Total**: Você gerencia todos os seus clientes
+✅ **Isolamento de Dados**: Cada cliente só vê os próprios dados
+✅ **Escalável**: Adicione quantos clientes quiser na mesma agência
+✅ **Identidade Visual**: Logo e cores personalizadas por agência
+
+## Fluxo de Trabalho
+
+1. **Agência se cadastra** → Cria subdomínio (ex: idealpages.aggios.app)
+2. **Agência personaliza** → Upload de logo, cores, identidade visual
+3. **Agência adiciona clientes** → Cada cliente recebe credenciais
+4. **Cliente acessa** → idealpages.aggios.app (vê marca da agência)
+5. **Cliente usa módulos** → CRM, ERP, Projetos (dados isolados)
+
+## Resposta Direta
+
+**Pergunta**: "Cliente precisa do CRM, mando aggios.app ou idealpages.aggios.app?"
+
+**Resposta**: **`idealpages.aggios.app`** ✅
+
+O cliente SEMPRE acessa o painel da sua agência, onde verá sua marca e terá acesso aos módulos que você liberar.
+
+---
+
+## Sistema de Links de Cadastro Personalizados
+
+### Visão Geral
+
+Sistema que permite ao SuperAdmin criar links de cadastro customizados, escolhendo:
+- **Campos do formulário**: Quais informações coletar
+- **Módulos habilitados**: Quais funcionalidades o cliente terá acesso
+- **Branding**: Logo e cores personalizadas
+
+### Fluxo de Uso
+
+1. **SuperAdmin** acessa `dash.aggios.app/superadmin/signup-templates`
+2. **Cria template** selecionando:
+   - Campos: email, senha, subdomínio, CNPJ, telefone, etc.
+   - Módulos: CRM, ERP, PROJECTS, FINANCIAL, etc.
+   - Slug: URL amigável (ex: `crm-rapido`)
+3. **Compartilha link**: `aggios.app/cadastro/crm-rapido`
+4. **Cliente acessa** e vê formulário personalizado
+5. **Após cadastro**, tenant criado com módulos específicos
+
+### Exemplo Real: DH Projects
+
+```
+Template: "CRM Rápido"
+Slug: crm-rapido
+Campos: email, senha, subdomínio, nome da empresa
+Módulos: CRM
+
+Link gerado: aggios.app/cadastro/crm-rapido
+
+Cliente preenche:
+- Email: contato@dhprojects.com
+- Senha: ********
+- Subdomínio: dhprojects
+- Empresa: DH Projects
+
+Resultado:
+✅ Tenant criado: dhprojects.aggios.app
+✅ Módulo CRM habilitado
+✅ Outros módulos desabilitados
+```
+
+### Estrutura Técnica
+
+**Backend:**
+- Tabela: `signup_templates`
+- Repository: `SignupTemplateRepository`
+- Handlers: `/api/admin/signup-templates` (CRUD)
+- Handler público: `/api/signup-templates/slug/{slug}` (renderiza form)
+
+**Frontend:**
+- Gerenciamento: `dash.aggios.app/superadmin/signup-templates`
+- Cadastro público: `aggios.app/cadastro/{slug}`
+
+**Campos Disponíveis:**
+- email, password, subdomain (obrigatórios)
+- company_name, cnpj, phone, address, city, state, zipcode (opcionais)
+
+**Módulos Disponíveis:**
+- CRM, ERP, PROJECTS, FINANCIAL, INVENTORY, HR
+
+### Benefícios
+
+✅ Cadastro rápido para clientes específicos
+✅ Coleta apenas informações necessárias
+✅ Habilita somente módulos contratados
+✅ Reduz fricção no onboarding
+✅ Personalização por caso de uso

+# System Instruction: Arquitetura de Layout com Sidebar Expansível
+
+**Role:** Senior React Developer & UI Specialist
+**Tech Stack:** React, Tailwind CSS (Sem bibliotecas de ícones ou fontes externas).
+
+**Objetivo:**
+Implementar um sistema de layout "Dashboard" composto por um **Menu Lateral (Sidebar)** que expande e colapsa suavemente e uma área de conteúdo principal.
+
+**Requisitos Críticos de Animação:**
+1. A transição de largura da sidebar deve ser suave (transition-all duration-300).
+2. O texto dos botões **não deve quebrar** ou desaparecer bruscamente. Use a técnica de transição de `max-width` e `opacity` para que o texto deslize suavemente para fora.
+3. Não utilize bibliotecas de animação (Framer Motion, etc), apenas Tailwind CSS puro.
+
+---
+
+## 1. Componente: `DashboardLayout.tsx` (Container Principal)
+
+Este componente deve gerenciar o estado global do menu (aberto/fechado) para evitar "prop drilling" desnecessário.
+
+```tsx
+import React, { useState } from 'react';
+import { SidebarRail } from './SidebarRail';
+
+interface DashboardLayoutProps {
+  children: React.ReactNode;
+}
+
+export const DashboardLayout: React.FC<DashboardLayoutProps> = ({ children }) => {
+  // Estado centralizado do layout
+  const [isExpanded, setIsExpanded] = useState(true);
+  const [activeTab, setActiveTab] = useState('home');
+
+  return (
+    <div className="flex h-screen w-full bg-gray-900 text-slate-900 overflow-hidden p-3 gap-3">
+      {/* Sidebar controla seu próprio estado visual via props */}
+      <SidebarRail 
+        activeTab={activeTab} 
+        onTabChange={setActiveTab}
+        isExpanded={isExpanded}
+        onToggle={() => setIsExpanded(!isExpanded)}
+      />
+
+      {/* Área de Conteúdo (Children) */}
+      <main className="flex-1 h-full min-w-0 overflow-hidden flex flex-col bg-white rounded-3xl shadow-xl relative">
+        {children}
+      </main>
+    </div>
+  );
+};
+```
+
+## 2. Componente: `SidebarRail.tsx` (Lógica de Animação)
+
+Aqui reside a lógica visual. Substitua os ícones por `<span>Icon</span>` ou SVGs genéricos para manter o código agnóstico.
+
+**Pontos de atenção no código abaixo:**
+*   `w-[220px]` vs `w-[72px]`: Define a largura física.
+*   `max-w-[150px]` vs `max-w-0`: Define a animação do texto.
+*   `whitespace-nowrap`: Impede que o texto pule de linha enquanto fecha.
+
+```tsx
+import React from 'react';
+
+interface SidebarRailProps {
+  activeTab: string;
+  onTabChange: (tab: string) => void;
+  isExpanded: boolean;
+  onToggle: () => void;

+## Integração com Agências
+
+Quando agência se cadastra:
+1. Seleciona um plano
+2. Sistema cria `Subscription` com status `active` ou `pending_payment`
+3. Agência herda limite de usuários do plano
+4. Ao criar usuário: validar se não ultrapassou limite
+
+---
+
+## Features Futuras
+- [ ] Editor de Features e Diferenciais (drag-drop no frontend)
+- [ ] Planos promocionais (duplicar existente, editar preço)
+- [ ] Validações de limite de usuários por plano
+- [ ] Dashboard com uso atual vs limite
+- [ ] Alertas quando próximo do limite
+- [ ] Integração com Stripe/PagSeguro

 # Aggios App
 
-Aplicação Aggios
+Plataforma composta por serviços de autenticação, painel administrativo (superadmin) e site institucional da Aggios, orquestrados via Docker Compose.
 
-## Descrição
+## Visão geral
+- **Objetivo**: permitir que superadministradores cadastrem e gerenciem agências (tenants) enquanto o site institucional apresenta informações públicas da empresa.
+- **Stack**: Go (backend), Next.js 16 (dashboard e site), PostgreSQL, Traefik, Docker.
+- **Status**: Sistema multi-tenant completo com segurança cross-tenant validada, branding dinâmico e file serving via API.
 
-Projeto em desenvolvimento.
+## Componentes principais
+- `backend/`: API Go com serviços de autenticação, operadores e CRUD de agências (endpoints `/api/admin/agencies` e `/api/admin/agencies/{id}`).
+- `front-end-agency/`: Painel Next.js para agências - branding dinâmico, upload de logos, gestão de perfil e autenticação tenant-aware.
+- `front-end-dash.aggios.app/`: painel Next.js – login do superadmin, listagem de agências, exibição detalhada e exclusão definitiva.
+- `frontend-aggios.app/`: site institucional Next.js com suporte a temas claro/escuro e compartilhamento de tokens de design.
+- `backend/internal/data/postgres/`: scripts de inicialização do banco (estrutura base de tenants e usuários).
+- `traefik/`: reverse proxy e certificados automatizados.
 
-### Atualização recente
+## Funcionalidades entregues
 
-- 07/12/2025: Site institucional (`frontend-aggios.app`) atualizado com suporte completo a dark mode baseado em Tailwind CSS v4 e `next-themes`.
+### **v1.4 - Segurança Multi-tenant e File Serving (13/12/2025)**
+- **🔒 Segurança Cross-Tenant Crítica**:
+  - Validação de tenant_id em endpoints de login (bloqueio de cross-tenant authentication)
+  - Validação de tenant em todas rotas protegidas via middleware
+  - Mensagens de erro genéricas (sem exposição de arquitetura multi-tenant)
+  - Logs detalhados de tentativas de acesso cross-tenant bloqueadas
   
-## Como Usar
+- **📁 File Serving via API**:
+  - Nova rota `/api/files/{bucket}/{path}` para servir arquivos do MinIO através do backend Go
+  - Eliminação de dependência de DNS (`files.localhost`) - arquivos servidos via `api.localhost`
+  - Headers de cache otimizados (Cache-Control: public, max-age=31536000)
+  - CORS e content-type corretos automaticamente
   
-Para configurar e executar o projeto, consulte a documentação em `docs/`.
+- **🎨 Melhorias de UX**:
+  - Mensagens de erro humanizadas no formulário de login (sem pop-ups/toasts)
+  - Erros inline com ícones e cores apropriadas
+  - Feedback em tempo real ao digitar (limpeza automática de erros)
+  - Mensagens específicas para cada tipo de erro (401, 403, 404, 429, 5xx)
+  
+- **🔧 Melhorias Técnicas**:
+  - Next.js middleware injetando headers `X-Tenant-Subdomain` para routing correto
+  - TenantDetector middleware prioriza headers customizados sobre Host
+  - Upload de logos retorna URLs via API ao invés de MinIO direto
+  - Configuração MinIO com variáveis de ambiente `MINIO_SERVER_URL` e `MINIO_BROWSER_REDIRECT_URL`
+
+### **v1.3 - Branding Dinâmico e Favicon (12/12/2025)**
+- **Branding Multi-tenant**: Logo, favicon e cores personalizadas por agência
+- **Favicon Dinâmico**: Atualização em tempo real via localStorage e SSR metadata
+- **Upload de Arquivos**: Sistema de upload para MinIO com bucket público
+- **Rate Limiting**: 1000 requisições/minuto por IP
+
+### **v1.2 - Redesign Interface Flat**
+- Adoção de design "Flat" (sem sombras), focado em bordas e limpeza visual
+- Gestão avançada de agências com filtros robustos
+- Detalhamento completo com visualização de branding
+
+### **v1.1 - Fundação Multi-tenant**
+- Login de Superadmin com JWT
+- Cadastro de Agências
+- Proxy Interno Next.js para chamadas autenticadas
+- Site Institucional com dark mode
+
+## Executando o projeto
+1. **Pré-requisitos**: Docker Desktop e Node.js 20+ (para utilitários opcionais).
+2. **Variáveis**: ajustar `.env` conforme referências existentes (`docker-compose.yml`, arquivos `config`).
+3. **Subir os serviços**:
+	```powershell
+	docker-compose up --build
+	```
+4. **Hosts locais**:
+	- Painel SuperAdmin: `http://dash.localhost`
+	- Painel Agência: `http://{agencia}.localhost` (ex: `http://idealpages.localhost`)
+	- Site: `http://aggios.app.localhost`
+	- API: `http://api.localhost`
+	- Console MinIO: `http://minio.localhost` (admin: minioadmin / M1n10_S3cur3_P@ss_2025!)
+5. **Credenciais padrão**: ver `backend/internal/data/postgres/init-db.sql` para usuário superadmin seed.
+
+## Segurança
+- ✅ **Cross-Tenant Authentication**: Usuários não podem fazer login em agências que não pertencem
+- ✅ **Tenant Isolation**: Todas rotas protegidas validam tenant_id no JWT vs tenant_id do contexto
+- ✅ **Erro Handling**: Mensagens genéricas que não expõem arquitetura interna
+- ✅ **JWT Validation**: Tokens validados em cada requisição autenticada
+- ✅ **Rate Limiting**: 1000 req/min por IP para prevenir brute force

+```
+
+## Testes e validação
+- Consultar `1. docs/TESTING_GUIDE.md` para cenários funcionais.
+- **Testes de Segurança**:
+  - ✅ Tentativa de login cross-tenant retorna 403
+  - ✅ JWT de uma agência não funciona em outra agência
+  - ✅ Logs registram tentativas de acesso cross-tenant
+- **Testes de File Serving**:
+  - ✅ Upload de logo gera URL via API (`http://api.localhost/api/files/...`)
+  - ✅ Imagens carregam sem problemas de CORS ou DNS
+  - ✅ Cache headers aplicados corretamente
+
+## Próximos passos sugeridos
+- Implementar soft delete e trilhas de auditoria para exclusão de agências
+- Adicionar validação de permissões por tenant em rotas de files (se necessário)
+- Expandir testes automatizados (unitários e e2e) focados no fluxo do dashboard
+- Disponibilizar pipeline CI/CD com validações de lint/build

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
