+- **Trabajo offline seguro:** Room conserva operaciones pendientes y WorkManager las sincroniza cuando vuelve la red, respetando el orden en que fueron creadas.
+- La cola offline queda separada por usuario autenticado para impedir que una sesión sincronice trabajo de otra persona en el mismo dispositivo.
+- Inspecciones, Actas, Inventario, Hallazgos, fotos, representante, manifestación y cierre conservan una identidad de cliente estable para reintentos idempotentes.
+- Las listas de trabajo, Inventario, Actas, cierres, Hallazgos y estado de firma usan caché local por usuario para poder consultar contexto ya descargado sin conectividad.
+- Antes de incorporar una foto de Hallazgo se muestra **Revisar fotografía** con **Usar esta foto**, **Volver a tomar** y **Eliminar foto**.
+- Corrige el cierre que enviaba `uploadMode=ONLINE`; el contrato vigente usa `IMMEDIATE` o `DEFERRED`.
+- La APK consulta el estado real de la firma reutilizable del Inspector y no afirma que existe cuando todavía no fue configurada.
+- El Dashboard de Actas prioriza el **PDF real del Acta** y muestra directamente las fotografías de Hallazgos y del Inventario relacionado.
+- En toda la interfaz activa, la antigua expresión “clasificación técnica” se presenta como **Tipo de instalación** o **Tipo de subinstalación**.
+
+- Corrige el cierre de Actas evitando `NaN` en el versionado de LOCKED/SEALED.
+- El cierre pasa a **Para firmar**; la APK captura sólo la manifestación/firma del acompañante.
+- La firma del Inspector se guarda una vez en Mi perfil y se copia de forma inmutable al sellar cada Acta.
+- Elimina la tarjeta duplicada del Acta seleccionada y simplifica la jerarquía visual inspirada en la referencia Figma.
+
+- El encabezado de **Mis inspecciones** separa las acciones para que **Salir** nunca se comprima ni se corte en pantallas angostas.
+- El alta de Hallazgos corrige la captura de versión que podía transformar el número en `NaN` después del INSERT y devolver error 500.
+- Un Hallazgo admite **múltiples fotografías con GPS**; después de cada captura queda disponible **Agregar otra foto con GPS** y se muestra el contador.

+# DH Android 0.19.1 · revisión de candidata
+
+## Idea funcional verificada contra código y API
+
+La app es la herramienta del inspector en campo. Oficina administra territorio, operadoras, clasificaciones, campos y catálogo; la APK consulta esas fuentes. Una Inspección contiene varias Actas, con una sola en elaboración simultánea. El Hallazgo pertenece al Acta y al elemento seleccionado. Cerrar contenido lo deja inmutable y pendiente de firma. Firma del inspector y manifestación/firma o negativa de empresa permiten sellar el Acta. La Inspección exige todas sus Actas activas selladas.
+
+Yacimiento, Instalación y Subinstalación son destinos de Hallazgos. Una Instalación nueva debe crearse dentro de un Yacimiento y una Subinstalación dentro de una Instalación compatible. El inventario nacido en campo necesita GPS y foto antes del Hallazgo.
+
+## Hallazgos corregidos
+
+| Problema observado | Corrección |
+| --- | --- |
+| Cuatro clientes renovaban por separado la misma sesión | Coordinador compartido; protege rotación, logout y cambio de usuario |
+| Cortes de red durante refresh borraban la sesión | Sólo una respuesta 401 de la sesión vigente la invalida |
+| Operaciones solapadas liberaban ocupado antes de terminar | Conteo de pendientes y rechazo del segundo guardado |
+| Respuestas de búsquedas antiguas sobrescribían resultados recientes | Generación de búsqueda y verificación del ID de inspección |
+| Un Acta anterior podía persistir al cambiar de inspección | Limpieza de estado de Acta al abrir otra inspección |
+| Coordenadas crudas excedían decimales admitidos | Normalización 6 decimales para coordenadas y 3 para precisión |
+| Inventario móvil ocultaba Yacimientos | Selección para Hallazgos y alta de Instalación dentro de Yacimiento |
+| Alta de Instalación podía adoptar otro tipo por fallback | Eliminado; pide elegir el Yacimiento padre correcto |
+| Datos técnicos por familia no estaban editables | Formulario conectado a technical-values; mismos campos de oficina |
+| Fallos de GPS/permisos en evidencia sin mensaje | Error visible y accionable |
+| Barras del sistema/teclado podían tapar controles | Insets de sistema y teclado en la raíz |
+
+## Evidencia automática
+
+25 pruebas Android: 8 contratos existentes y 17 pruebas nuevas de comportamiento (sesión 7, concurrencia 3, GPS 3, campos técnicos 4). Lint debug/release y compilación debug/release en workflow Android. CI general comprueba API, WEB, scripts y migraciones; la auditoría de dependencias se ejecuta separadamente. Consultar las ejecuciones del SHA de la entrega, no sólo un resultado anterior.
+
+## Límites de esta candidata
+
+- Requiere conexión. No existe cola persistente offline ni resolución de conflictos sin señal.
+- Un timeout de escritura puede ocurrir después de guardar en servidor. Revisar el registro antes de repetir; no se afirma idempotencia general de todas las escrituras.
+- Los datos técnicos por familia se completan en un paso separado tras seleccionar/crear el elemento. GPS/foto continúa siendo la barrera de Hallazgos del servidor.
+- No se ejecutó aceptación en tablet física: quedan por comprobar cámara, GPS, biometría, rotación/recreación de actividad, firmas y actualización sobre la APK instalada.
+- La release compila sin firma. Se requiere la clave histórica y su certificado de referencia para distribuir una actualización productiva. No crear otra clave como sustituto.
+- La candidata debug usa com.korexlabs.dhinspeccion.debug y no reemplaza la app productiva. La compatibilidad con una debug anterior depende también de su certificado; no desinstalar una app con información pendiente sin revisar antes.
+
+## Recorrido de aceptación en tablet
+
+1. Ingresar con inspector y cargar inspecciones asignadas.
+2. Iniciar una inspección, crear Acta, seleccionar Yacimiento/Instalación/Subinstalación.
+3. Crear Instalación bajo Yacimiento y Subinstalación compatible; probar GPS permitido/denegado y foto tomada/cancelada.
+4. Completar campos técnicos requeridos, incluyendo No booleano, decimal con coma, fecha y opción de lista; volver a abrir para comprobar persistencia.
+5. Crear Hallazgo catalogado y OTROS, adjuntar evidencia.
+6. Cerrar contenido, comprobar inmutabilidad y estado Pendiente de firma.
+7. Registrar firmas o negativa de empresa; sellar Acta.
+8. Crear otra Acta, comprobar que una pendiente impide cerrar la Inspección; completar y cerrar.
+9. Cortar conexión y recuperarla: errores visibles, sin pérdida de sesión por red ni falso aviso de guardado.
+10. Verificar en Dashboard los mismos registros y documentos.
