+
+Control plane multi-tenant para orquestrar provedores BaaS (Appwrite, Supabase) com foco em provisioning, schema, secrets, métricas e auditoria.
+
+## Visão geral
+- Backend Node.js + TypeScript com Fastify
+- Multi-tenant com isolamento lógico por tenant
+- Providers plugáveis sem lógica de negócio
+- Serviços centrais para provisioning, schema, secrets, finops e audit
+
+## Arquitetura
+```
+/src
+  /core
+  /providers
+  /modules
+  /lib
+  main.ts
+```
+
+Detalhes adicionais em [docs/architecture.md](docs/architecture.md).
+
+## Fluxo multi-tenant
+1. Criar tenant (`POST /tenants`)
+2. Criar projeto para o tenant (`POST /tenants/:id/projects`)
+3. Provisionar projeto no provider (`POST /projects/:id/provision`)
+4. Sincronizar schema (`POST /projects/:id/schema/sync`)
+5. Coletar métricas (`GET /projects/:id/metrics`)
+
+## Como adicionar um novo provider
+1. Criar pasta em `src/providers/<provider>`
+2. Implementar `client`, `provisioning`, `schema`, `metrics`
+3. Registrar no `provider.factory.ts`
+4. Adicionar variáveis em `.env.example` e no `SecretsService`
+
+## Como subir localmente
+```bash
+cp .env.example .env
+npm install
+npm run dev
+```
+
+### Docker
+```bash
+docker compose up --build
+```
+
+## API mínima
+- `POST /tenants`
+- `GET /tenants`
+- `POST /tenants/:id/projects`
+- `GET /tenants/:id/projects`
+- `POST /projects/:id/provision`
+- `POST /projects/:id/schema/sync`
+- `GET /projects/:id/metrics`
+- `GET /health`

+# Arquitetura
+
+O `baas-control-plane` implementa um control plane modular para gerenciar múltiplos provedores BaaS de forma multi-tenant. Ele centraliza provisioning, schema, secrets, métricas e auditoria sem executar workloads de clientes.
+
+## Camadas
+- **core**: tipos e interface dos providers.
+- **providers**: implementações técnicas de Appwrite e Supabase.
+- **modules**: serviços de negócio (tenants, projects, provisioning, schema, secrets, finops, audit).
+- **lib**: utilitários de ambiente, logger e HTTP.
+
+## Fluxo básico
+1. Tenant é criado e armazenado.
+2. Projeto é criado e vinculado a um provider.
+3. Provisioning aciona o provider e salva o `externalId`.
+4. Schema é versionado e aplicado via provider.
+5. FinOps coleta métricas normalizadas.
+6. Auditoria registra eventos relevantes.

+# Providers
+
+Os providers implementam apenas comandos técnicos e não contêm regras de negócio.
+
+## Interface obrigatória
+- `createProject`
+- `deleteProject`
+- `applySchema`
+- `collectMetrics`
+- `rotateSecrets`
+- `healthCheck`
+
+## Implementações iniciais
+- Appwrite: `src/providers/appwrite`
+- Supabase: `src/providers/supabase`
+
+## Extensão
+1. Crie `src/providers/<provider>`
+2. Implemente `ProviderInterface`
+3. Registre no `provider.factory.ts`
+4. Configure secrets no `SecretsService`

+# Segurança
+
+## Princípios
+- Providers não acessam `.env` diretamente.
+- Secrets são entregues via `SecretsService`.
+- Preparado para integração com Vault/Infisical.
+
+## Boas práticas
+- Não faça hardcode de credenciais.
+- Rotacione secrets via `rotateSecrets`.
+- Audite eventos críticos (tenant, projeto, schema, secrets).

-
-- CRUD de tenants e projetos Appwrite (multi-tenant).

-## Rodando localmente

-# Segurança e Permissões do Appwrite
-
-As coleções do projeto seguem uma política de Row-Level Security (RLS) para proteger os dados dos usuários e os registros de auditoria.
-
-## Princípios gerais
-- Cada documento pertence a um usuário autenticado, identificado pelo `userId` armazenado no documento.
-- Operações de leitura e gravação são restritas ao proprietário do documento (role `member`).
-- Logs de auditoria globais só podem ser consultados por usuários com a role `admin`.
-
-## Regras por coleção
-
-### `cloud_accounts`
-- **Leitura**: apenas o usuário que criou o documento (role `member`).
-- **Criação**: apenas usuários autenticados.
-- **Atualização/Exclusão**: somente o proprietário do documento.
-
-### `projects`
-- **Leitura**: restrita ao proprietário do documento.
-- **Criação**: usuários autenticados podem criar seus próprios registros.
-- **Atualização/Exclusão**: apenas o proprietário do documento.
-
-### `audit_logs`
-- **Leitura**: exclusiva para usuários com role `admin` (para auditoria global).
-- **Criação**: serviços e funções podem registrar ações em nome dos usuários; cada entrada mantém o `userId` responsável.
-- **Atualização/Exclusão**: não permitidas para usuários finais; apenas processos administrativos podem gerenciar retenção.
-
-## Considerações adicionais
-- Tokens e chaves sensíveis (GitHub, Cloudflare) devem ser armazenados em `cloud_accounts` e nunca enviados ao frontend.
-- Funções Cloud (como as de proxy) devem validar o `userId` associado ao documento antes de usar qualquer chave.
-- Revogue ou rotacione chaves comprometidas removendo ou atualizando o documento correspondente na coleção.

-O script `setup-appwrite.ts` aplica o schema base (database, collections, buckets e functions)
-para um projeto Appwrite específico.

-## Variáveis necessárias
-
-Edite `backend/.env` e configure:
-
-```env

-APPWRITE_SETUP_PROJECT_ID=<project_id>
