 # DH Inspección V2
 
-Versión: **0.19.5-1**  
-Fase: **D5.5.1 · Corrección de staging de planificación**
+Repositorio del sistema DH Inspección V2.
 
-D5.5.1 conserva íntegramente D5.5 y corrige únicamente el contrato de pruebas de staging. D5.5 consolida la preparación de visitas desde oficina antes del trabajo de campo. La visita queda anclada explícitamente a Área y Organización operadora, y el sistema genera un checklist auditable con antecedentes, respuestas vencidas, controles vencidos y próximos controles.
+## Componentes
 
-## Alcance D5.5
+- `api-v3/`: API NestJS/TypeORM y contratos de dominio.
+- `web-v2/`: aplicación WEB React/Vite.
+- `android-app/`: aplicación Android para trabajo de campo.
+- `scripts/`: utilidades operativas, preflight y despliegue.
+- `docs/`: documentación funcional y técnica.
 
-- selección web Área → Organización operadora vigente;
-- fecha y equipo inspector dentro del plan;
-- checklist automático versionado y append-only;
-- respuestas de empresa vencidas y controles de verificación vencidos;
-- próximos controles dentro de 30 días de la fecha planificada;
-- antecedentes históricos del mismo contexto;
-- incorporación automática de registros accionables;
-- alta manual de registros preventivos del mismo Área/Operadora;
-- exclusiones sólo mediante motivo auditable;
-- reincorporación sin borrar la exclusión histórica;
-- visitas de verificación integradas al mismo contrato de planificación;
-- cambio de contexto o fecha invalida el checklist hasta regeneración explícita;
-- inicio de visita exclusivamente desde APK mediante la política móvil ya existente.

+## Contratos que no deben romperse
 
-## Despliegue
+- Inventario físico: **Departamento → Área → Yacimiento → Instalación → Subinstalación**.
+- Empresa es un maestro independiente; la Operadora se relaciona temporalmente con Área.
+- Una Inspección puede tener múltiples Actas, pero sólo un Acta `DRAFT` simultánea.
+- Hallazgos directos: Yacimiento, Instalación y Subinstalación, siempre con `OTROS` disponible.
+- La APK puede abrir una Inspección reutilizando el lifecycle canónico del backend.
+- GEDO/IF oficializa el Informe, pero no activa por sí solo el vencimiento No urgente.
 
-El despliegue debe partir exactamente de API/WEB **0.19.4-1** y ejecutar `scripts/deploy-phase-d5-5.sh`. Antes de modificar producción, el script compila API y web en staging y exige **252 tests** aprobados.
+Las reglas detalladas, el procedimiento de cambio seguro y el recorrido de demo están en los documentos enlazados arriba.

+# DH Inspección Android · release de campo 0.19.11
+
+## Candidata vigente
+
+- `versionName`: **0.19.11**; `versionCode`: **39**.
+- API: `https://dhv2.korexlabs.com/api/v3/`; compatible con API 0.29.0-9 / WEB 0.23.0-6.
+- Antes de cerrar el contenido, el inspector escribe una descripción real de lo actuado.
+- La descripción se sincroniza antes del bloqueo, también cuando se trabajó sin conexión.
+- Un acta anterior, ya sellada, conserva el texto originalmente registrado.
+
+## Referencia de 0.19.10
+
+### Candidata anterior
+
+- Fase funcional: **Flujo final de campo · Inspección → Acta → Hallazgos → Firma**.
+- `versionName`: **0.19.10**.
+- `versionCode`: **38**.
+- Application ID release: `com.korexlabs.dhinspeccion`.
+- Application ID debug/QA: `com.korexlabs.dhinspeccion.debug`.
+- API: `https://dhv2.korexlabs.com/api/v3/`.
+- Servidor compatible de esta candidata: **API 0.29.0-8 / WEB 0.23.0-5**.
+
+La variante debug es independiente de la app productiva y puede instalarse para QA/presentación sin sobrescribir una instalación release histórica.
+
+### Ajustes 0.19.10
+
+- **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.
+
+## Procedimiento operativo validado
+
+La APK 0.19.10 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.
+3. **Agregar Hallazgos**. Recién desde esta acción se selecciona la Instalación/Subinstalación afectada.
+4. Si el elemento ya existe, se lo selecciona desde el Inventario del Área/Yacimiento de la Inspección.
+5. Si no existe, se da de alta desde campo sin abandonar el Acta.
+6. Un elemento nuevo debe completar **GPS + fotografía** antes de poder recibir Hallazgos.
+7. Antes del cierre se identifican, para esa Acta, los datos del **Representante de la empresa** que acompañó el recorrido: nombres y apellidos, DNI, cargo/función y email. Si coincide con el Acta anterior, la APK puede precargarlos, pero deben confirmarse nuevamente.
+8. Al terminar el contenido del Acta se elige **Urgente / No urgente** y luego se usa **Cerrar contenido y pasar a firma**. La urgencia pertenece al Acta completa, nunca a cada Hallazgo; desde ese momento el contenido queda inmutable y el estado visible es **Para firmar**.
+9. En **Para firmar**, el acompañante de la empresa registra su manifestación: **conformidad**, **disconformidad con motivo obligatorio**, **negativa a firmar con motivo obligatorio** o **ausencia documentada**. La firma del Inspector no se dibuja en la tablet: se guarda una sola vez desde **Mi perfil** del Dashboard y el servidor copia esa firma de forma inmutable a cada Acta al usar **Aplicar mi firma y cerrar Acta**.
+10. La Inspección sólo puede cerrarse cuando todas sus Actas no canceladas están firmadas y cerradas.
+
+La nomenclatura técnica interna de API (`DRAFT`, `LOCKED`, `SEALED`, etc.) no se muestra al inspector: la interfaz usa textos operativos en castellano.
+
+## Alta de Instalaciones y Subinstalaciones
+
+El alta móvil queda alineada con el Dashboard y con las validaciones del servidor.
+
+### Instalación
+
+- contexto territorial: Yacimiento/Área de la Inspección;
+- clasificación técnica compatible;
+- **Nombre técnico** obligatorio;
+- Nombre habitual opcional;
+- Descripción opcional;
+- atributos técnicos definidos por el tipo; sólo los marcados como obligatorios bloquean el guardado;
+- código DH generado por el sistema cuando corresponde;
+- GPS de la tablet;
+- fotografía obligatoria antes de crear Hallazgos.
+
+### Subinstalación
+
+Además de lo anterior requiere elegir primero la **Instalación padre**. El buscador consulta mientras se escribe y cada resultado es seleccionable tocando la tarjeta.
+
+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.
+
+## Actas y firma
+
+La terminología visible se simplifica:
+
+- `DRAFT` → **En elaboración**;
+- `LOCKED` → **Pendiente de firma**;
+- `SEALED` → **Firmada y cerrada**.
+
+Cerrar el contenido no cierra automáticamente la Inspección y tampoco obliga a terminar la firma en ese instante: puede continuarse con otra Acta. La urgencia se decide en ese cierre, nunca al crear el borrador. Una vez cerrado el contenido, el Acta es inmutable.
+
+Después de la firma/cierre definitivo se mantiene el circuito documental existente: PDF del Acta e informe INF editable (DOCX) para oficina.
+
+## Castellano e identidad visual
+
+Se revisaron las pantallas activas de campo para evitar exponer estados y opciones internas en inglés. Entre otros cambios: Pasaporte/Otro en documentos, estados de Inspección/Acta/Hallazgo en castellano, Correo electrónico, Huella de integridad y terminología de cierre orientada al usuario.
+
+La pantalla de ingreso y el desbloqueo biométrico utilizan la identidad visual de Mendoza ya incorporada al proyecto.
+
+## Barrera obligatoria
+
+Todo cambio Android o de API que pueda afectar al cliente móvil debe pasar `Android CI / RC`:
+
+1. validación de identidad, HTTPS y políticas básicas del manifest;
+2. Android lint;
+3. pruebas unitarias Android reales, con verificación de que exista al menos una prueba ejecutada;
+4. `assembleDebug`;
+5. `assembleRelease` para comprobar que la variante productiva compile;
+6. empaquetado del APK debug con SHA-256 y metadata de commit/versionado.
+
+Además, `DH V2 CI` debe mantener verdes API, WEB y contrato Docker/migraciones antes de promover cambios que afecten al servidor.
+
+## Firma release
+
+La clave histórica de firma **no se versiona ni se reemplaza**. La CI compila la variante release para detectar roturas, pero una APK productiva que deba actualizar `com.korexlabs.dhinspeccion` tiene que firmarse con la clave histórica.
+
+No se debe crear una clave nueva para resolver una falta de acceso: eso rompería la continuidad de actualización de tablets que ya tengan una versión firmada con la clave anterior.
+
+## Criterio de distribución
+
+Antes de distribuir una APK productiva:
+
+- todas las barreras de CI del SHA exacto deben estar verdes;
+- comprobar certificado/huella de firma contra la versión histórica si se distribuirá como actualización productiva;
+- realizar actualización sobre al menos una tablet con la versión productiva anterior cuando corresponda;
+- ejecutar smoke funcional: ingreso, iniciar Inspección, crear Acta, seleccionar/crear Instalación o Subinstalación, GPS/foto, Hallazgo, cerrar Acta → Pendiente de firma, firma/manifestación, cierre de Acta y cierre de Inspección;
+- registrar el SHA Git y SHA-256 de la APK distribuida.
+
+## Revisión 0.19.1
+
+- Renovación de sesión coordinada entre los cuatro clientes API; no cierra sesión por pérdida de red, HTTP 429/500 o cancelación.
+- Una respuesta tardía no puede restaurar una sesión cerrada ni usar la de otro inspector.
+- Guardia de escrituras contra doble toque y conteo correcto de operaciones pendientes.
+- Búsquedas descartan respuestas antiguas. Cambio de inspección limpia el Acta anterior.
+- Mensajes visibles de permisos/GPS en evidencia y respeto de barras de sistema/teclado.
+- Diez nuevas pruebas de comportamiento sobre sesión y concurrencia.
+
+### Alcance real
+
+Esta candidata requiere conexión. No implementa trabajo offline ni cola persistente de sincronización; un fallo de red no equivale a guardado. Tras un timeout de escritura debe verificarse el registro antes de repetir. No se presenta el artefacto debug como una release productiva. La firma histórica y el smoke en tablet siguen siendo requisitos para distribuir la release final.
+
+### Segunda pasada funcional
+
+- Coordenadas normalizadas al contrato API (6 decimales, precisión 3).
+- Yacimiento seleccionable para Hallazgos y como padre explícito de nuevas Instalaciones. Se elimina el fallback que podía presentar un tipo Yacimiento como alta de Instalación.
+- Formulario Datos técnicos sobre el elemento seleccionado: carga y guarda las definiciones/valores por familia mediante los endpoints existentes del Dashboard; valida obligatorios, números, Sí/No, fechas y opciones. Es un paso separado del alta estructural y GPS/foto.
+- Se agregan siete pruebas para coordenadas y valores técnicos.
+
+
+## Revisión 0.19.3 · flujo conceptual corregido
+
+- Se elimina **Inventario de campo** como acción independiente de la pantalla de Inspección.
+- El alta o selección de Inventario existe únicamente dentro de **Agregar Hallazgo**.
+- El borrador de Acta nace vacío, sin Inventario y sin urgencia predeterminada.
+- La urgencia se exige al cerrar el Acta y se persiste en la misma operación que la vuelve inmutable.
+- `inspection_acts.urgency` puede quedar pendiente durante el borrador; el bloqueo exige la decisión y calcula el vencimiento desde allí.

+# 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.
