- [ ] Persistencia total: Tudo eh salvo?
- [ ] Modular: Sem lock-in?

### Camadas
- [ ] Camada Humana: Decisoes nao delegadas?
- [ ] Camada Sistema: Validacoes aplicadas?
- [ ] Camada Cognitiva: AI apenas analisa/sintetiza?

### Governanca
- [ ] Persona apropriada selecionada?
- [ ] Guardrails incluidos no prompt?
- [ ] Input validado antes da AI?
- [ ] Output validado depois da AI?

### Auditoria
- [ ] request_id unico gerado?
- [ ] Todos os campos persistidos?
