 La variante debug es independiente de la app productiva y puede instalarse para QA/presentación sin sobrescribir una instalación release histórica.

+La APK 0.19.7 fija como recorrido principal de campo:
 
 1. **Iniciar Inspección**. Al iniciarla se habilita el circuito de **Actas y Hallazgos**; Inventario no es una acción independiente de la Inspección.
 2. **Crear o abrir un Acta**. Puede haber varias Actas dentro de una misma Inspección, pero sólo una puede permanecer en elaboración al mismo tiempo. La urgencia todavía no se define.

 La clasificación y los atributos se obtienen dinámicamente desde el mismo catálogo administrado por el Dashboard; la APK no mantiene listas técnicas paralelas.
 
+## Alta de Hallazgos
+
+El alta de Hallazgos usa un selector desplegable con búsqueda por nombre. La pantalla muestra sólo la información necesaria para decidir, mantiene **Otro / No está en la lista** como salida manual y evita exponer códigos o leyendas internas del catálogo. La fecha de corrección no se solicita al inspector al crear un Hallazgo; los plazos administrativos se gestionan fuera de este alta de campo. Los campos de carga son compactos y el teclado avanza con **Siguiente** entre ellos.
