+# 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.
