## Flujo de Trabajo
|
|
|
|
### Antes de implementar:
|
|
1. **Leer** `/docs/01-fase-alcance-inicial/MAI-{XXX}/` para el módulo
|
|
2. **Revisar** especificaciones técnicas en `/especificaciones/`
|
|
3. **Verificar** directivas específicas y heredadas
|
|
4. **Consultar** implementación en core si extiende
|
|
|
|
### Durante implementación:
|
|
1. **Extender** entidades de core cuando aplique
|
|
2. **Implementar** multi-tenant en todas las queries
|
|
3. **Seguir** nomenclatura de construcción
|
|
4. **Crear** tests unitarios
|
|
|
|
### Después de implementar:
|
|
1. **Registrar** en trazas: `/orchestration/trazas/TRAZA-TAREAS-BACKEND.md`
|
|
2. **Actualizar** inventario de módulos
|
|
3. **Ejecutar PROPAGACIÓN** según `core/orchestration/directivas/simco/SIMCO-PROPAGACION.md`
|
|
|
|
