+-- Migration: Corrige policy perigosa na tabela ai_description_queue
+-- Auditoria 2026-06-02 — RISCO-1 identificado
+--
+-- Problema: Policy "ai_queue_service_all" com USING(true) permite
+-- que QUALQUER usuário autenticado leia/escreva/delete filas de IA,
+-- criando risco de IDOR (Insecure Direct Object Reference).
+--
+-- Solução: Substituir por políticas granulares de mínimo privilégio:

+--   - DELETE: somente admins
