+# Agent Gemini - Log de Evolução do Projeto Aggios
+
+Este arquivo documenta as contribuições do Agente Code AI (Gemini) e a compreensão técnica consolidada sobre o ecossistema Aggios.
+
+## 🚀 Visão Geral do Projeto
+O **Aggios** é uma plataforma SaaS multi-tenant focada em agências, oferecendo uma suíte "all-in-one" que inclui CRM, ERP, Gestão de Projetos, entre outros.
+
+### Stack Tecnológica
+- **Frontend:** Next.js (App Router), TypeScript, Tailwind CSS, Headless UI.
+- **Backend:** Go (Golang) com roteamento `gorilla/mux`.
+- **Banco de Dados:** PostgreSQL (migrações SQL puras).
+- **Infraestrutura:** Docker Compose (backend, agency-frontend, minio, postgres, redis).
+
+---
+
+## 🛠️ Contribuições do Agente (Dezembro/2025)
+
+### 1. Módulo ERP - Finanças & Caixa
+- **Gestão de Múltiplas Contas:** Implementação completa (CRUD) de contas bancárias no backend e frontend.
+- **Controle de Saldo em Tempo Real:** Desenvolvimento da lógica de repositório em Go para atualizar o `current_balance` de contas baseando-se no status das transações financeiras (`paid`, `pending`).
+- **Resumo Financeiro:** Refatoração dos cartões de estatísticas para exibir o "Saldo de Caixa" real (somatório de contas) em vez de apenas totais de lançamentos filtrados.
+- **Dashboard ERP Real:** Dados reais, gráficos automáticos e filtros de status/data avançados.
+- **Módulo de Documentos:** Implementado sistema de documentos (estilo Google Docs) com editor de texto e gestão por tenant.
+
+### 2. UI/UX & Design System (Padrão Aggios)
+- **Refinação Minimalista Flat:** Aplicação do padrão visual "Clean & Flat" na página de finanças, removendo sombras pesadas e mantendo foco no contraste e tipografia.
+- **Componentização:** Utilização e refinamento de componentes em `components/ui` (Input, CustomSelect, DataTable).
+- **Barra de Busca:** Implementação de busca reativa integrada ao `Input` padronizado.
+
+### 3. Otimização e Reatividade
+- **Correção de Cache da API:** Configuração de `cache: 'no-store'` nas chamadas de serviço para garantir integridade dos dados sem necessidade de recarregar a página (F5).
+- **Sync de Estado:** Ajuste nos handlers do React para usar `await fetchData()` em todas as operações de escrita, garantindo que a UI reflita as mudanças do backend instantaneamente.
+
+### 4. Novas Funcionalidades (27 de Dezembro de 2025)
+- **Ações em Lote (Bulk Actions):** Implementação de seleção múltipla em transações financeiras e produtos. Adição de barra de ações flutuante para exclusão em massa e atualização de status coletiva.
+- **Melhorias no Dashboard & Filtros:** Refinamento dos filtros de data, busca reativa e integração de ações em lote nos módulos de "Contas a Pagar" e "Contas a Receber".
+- **Gestão de Contas Bancárias:** Refatoração da interface de contas (cards) com feedback visual de saldo e integração direta com o fluxo de caixa.
+
+---
+
+## 🧠 Entendimento Técnico do Sistema
+
+### Arquitetura de Soluções
+O sistema utiliza um sistema de **Solutions** vinculadas a **Planos**.
+- Slugs identificados: `crm`, `erp`, `projetos`, `helpdesk`, `pagamentos`, `contratos`, `documentos`, `social`.
+- O acesso é controlado via `SolutionGuard` no frontend e middleware de tenant no backend.
+
+### Estrutura de Autenticação
+- **Níveis de Acesso:** `SUPERADMIN` (Aggios), `ADMIN_AGENCIA` (Dono da agência/Tenant), `CLIENTE` (Portal do Cliente).
+- **Segurança:** JWT armazenado no `localStorage` com envio no header `Authorization`.
+
+### Padrão de Design "Aggios Pattern"
+- **Cards:** Bordas sutis (`zinc-100/800`), sem sombras, `rounded-2xl` ou `[32px]`.
+- **Botões:** Uso de gradientes (`var(--gradient)`) para ações primárias e visual flat para secundárias.
+- **Feedback:** Uso intensivo de `react-hot-toast` para notificações de sucesso/erro.
+
+---
+
+## 🛠️ Diretrizes de Desenvolvimento
+
+### 📋 Uso de Templates e Padronização
+Para manter a consistência visual e técnica do ecossistema Aggios, o Agente deve seguir rigorosamente estas regras:
+
+1.  **Aggios App Pattern:** Sempre basear novas telas e funcionalidades no workflow `aggios-app-pattern.md`. Isso garante que a hierarquia visual (PageHeader -> StatsCards -> Tabs -> DataTable) seja preservada.
+2.  **Componentes UI Reutilizáveis:** Nunca criar elementos de interface ad-hoc se existir um componente correspondente em `components/ui`. Priorizar o uso de:
+    -   `DataTable` para listagens.
+    -   `Input` e `CustomSelect` para formulários e buscas.
+    -   `StatsCard` para indicadores numéricos e financeiros.
+3.  **Visual Minimalista Flat:** Evitar o uso de sombras (`shadow`), utilizando bordas sutis (`border-zinc-100` / `dark:border-zinc-800`) e fundos contrastantes para separar camadas.
+4.  **Reatividade Garantida:** Manter o padrão de execução assíncrona com `await fetchData()` e desativação de cache da API para que os templates reflitam mudanças instantaneamente sem recarregar a página.
+5.  **Rebuild de Containers:** Sempre que houver mudanças estruturais no frontend (especialmente no `front-end-agency`), é necessário rodar `docker-compose up -d --build agency` para refletir as alterações no ambiente de produção/Docker.

+description: Padrão de Design Aggios App para Páginas de Listagem e Dashboards
+---
+
+# Padrão de Design Aggios App
+
+Este workflow descreve como construir uma página seguindo o design system da Aggios, utilizando os componentes padronizados na pasta `components/ui`.
+
+## 1. Estrutura Básica da Página
+
+Toda página deve ser envolvida por um container com padding e largura máxima:
+
+```tsx
+<div className="p-6 max-w-[1600px] mx-auto space-y-6">
+    {/* Conteúdo aqui */}
+</div>
+```
+
+## 2. Cabeçalho (`PageHeader`)
+
+Utilize o `PageHeader` para títulos, descrições e ações globais da página.
+
+```tsx
+<PageHeader
+    title="Título da Página"
+    description="Breve descrição da funcionalidade."
+    primaryAction={{
+        label: "Novo Item",
+        icon: <PlusIcon className="w-4 h-4" />,
+        onClick: () => handleCreate()
+    }}
+/>
+```
+
+## 3. Cartões de Estatísticas (`StatsCard`)
+
+Para dashboards ou resumos, utilize o grid de stats:
+
+```tsx
+<div className="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-6">
+    <StatsCard 
+        title="Métrica"
+        value="R$ 1.000"
+        icon={<CurrencyDollarIcon className="w-6 h-6" />}
+        trend={{ value: '10%', label: 'vs ontem', type: 'up' }}
+    />
+</div>
+```
+
+## 4. Filtros e Pesquisa (Minimalista Flat)
+
+Os filtros não devem ter sombras nem cores de marca no estado inicial/focus. Devem usar um visual "Clean" com contraste sólido.
+
+```tsx
+<div className="flex flex-col md:flex-row gap-4 items-center">
+    <div className="flex-1 w-full">
+        <Input
+            placeholder="Pesquisar..."
+            leftIcon={<MagnifyingGlassIcon className="w-5 h-5 text-zinc-400" />}
+            className="bg-white dark:bg-zinc-900 border-zinc-200 dark:border-zinc-800 focus:border-zinc-400 dark:focus:border-zinc-500"
+        />
+    </div>
+    <div className="w-full md:w-80">
+        <DatePicker 
+            value={dateRange}
+            onChange={setDateRange}
+            buttonClassName="bg-white dark:bg-zinc-900 border-zinc-200 dark:border-zinc-800 text-zinc-700 dark:text-zinc-300 hover:border-zinc-400"
+        />
+    </div>
+    <div className="w-full md:w-56">
+        <CustomSelect 
+           value={status}
+           onChange={setStatus}
+           options={[
+               { label: 'Todos', value: 'all' },
+               { label: 'Ativo', value: 'active', color: 'bg-emerald-500' },
+           ]}
+           buttonClassName="bg-white dark:bg-zinc-900 border-zinc-200 dark:border-zinc-800 hover:border-zinc-400"
+        />
+    </div>
+</div>
+```
+
+## 5. Abas e Tabelas (`Tabs` & `DataTable`)
+
+Para organizar o conteúdo principal, utilize o componente `Tabs`. Dentro de cada aba, utilize `Card` com `noPadding` para envolver a `DataTable`.
+
+```tsx
+<Tabs
+    variant="pills" // ou 'underline'
+    items={[
+        {
+            label: 'Listagem',
+            icon: <TableIcon />,
+            content: (
+                <Card noPadding title="Itens" description="Gerenciamento de registros.">
+                    <DataTable 
+                        columns={COLUMNS}
+                        data={DATA}
+                        pagination={{ ... }}
+                    />
+                </Card>
+            )
+        }
+    ]}
+/>
+```
+
+## Regras de Estilo e Cores
+- **Botões Primários**: Sempre use `variant="primary"` e aplique o gradiente via style/classe: `style={{ background: 'var(--gradient)' }} className="shadow-lg shadow-brand-500/20"`.
+- **Bordas**: Use `border-zinc-200` para light mode e `dark:border-zinc-800` para dark mode.
+- **Backgrounds**: Use `bg-white` (light) e `dark:bg-zinc-900` (dark) para componentes elevados.
+- **Cards & Containers (Flat Design)**:
+    - **Cards:** Fundo branco/zinc-900, bordas sutis (`border-zinc-200` / `dark:border-zinc-800`), **SEM SOMBRAS**.
+    - **Border Radius:** Usar `rounded-2xl` (16px) ou `rounded-[32px]` para containers grandes.
+    - **StatsCards:** Texto de valor em `font-bold` ou `font-black`, ícones em boxes coloridos com opacidade 10% no dark mode.
+    - **Hover:** Apenas transições de cor ou escalas sutis, evitar sombras no hover.

+
+### Segurança
+
+- JWT + Refresh tokens
+- Password hashing (Argon2)
+- Rate limiting (5 req/min em prod, 30 em dev)
+- CORS configurado
+- Security headers

+
+### Escalabilidade
+
+- Multi-tenant isolado por tenant_id
+- Índices em FK e campos frequentes
+- Redis para cache de sessions

+# Arquitetura Multi-tenant - Modelo de Negócio Aggios
+
+## Visão Geral da Plataforma
+
+A plataforma Aggios utiliza uma arquitetura multi-tenant em três camadas principais:
+
+```

+   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

+## 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';

+## 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 Soluções Alpha (ERP e Documentos), CRM Beta (leads, funis, campanhas), portal do cliente, 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}`). Inclui handlers para CRM (leads, funis, campanhas), portal do cliente e exportação de dados.
+- `front-end-agency/`: Painel Next.js para agências - branding dinâmico, upload de logos, gestão de perfil, CRM completo com Kanban, portal de cadastro de clientes 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) + migrações para CRM, funis e autenticação de clientes.
+- `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`.

+  - Dashboard de performance de campanhas
+  
+- **👥 Portal do Cliente**:
+  - Sistema de registro público de clientes
+  - Autenticação dedicada para clientes (JWT separado)
+  - Dashboard personalizado com estatísticas
+  - Visualização de leads e listas compartilhadas

+### **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
+  
+- **📁 File Serving via API**:
+  - Nova rota `/api/files/{bucket}/{path}` para servir arquivos do MinIO através do backend Go

+  
+- **🔧 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`
+

+
+### **v1.2 - 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`)
+	- Portal do Cliente: `http://{agencia}.localhost/cliente` (cadastro e área logada)
+	- 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

+  - ✅ 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
 
 ## Repositório
