 # DH Inspección V2
 
-Versión: **0.19.5-1**  
+Repositorio del sistema DH Inspección V2.
-Fase: **D5.5.1 · Corrección de staging de planificación**
 
-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;
+## Documentación 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.

-## 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 F6.1
+
+## Candidata vigente
+
+- Fase funcional: **F6.1**.
+- `versionName`: **0.15.1**.
+- `versionCode`: **23**.
+- Application ID release: `com.korexlabs.dhinspeccion`.
+- Application ID debug/QA: `com.korexlabs.dhinspeccion.debug`.
+- API: `https://dhv2.korexlabs.com/api/v3/`.
+- Launcher de presentación: adaptación vectorial local inspirada en el escudo institucional publicado por Gobierno de Mendoza en `mendoza.gov.ar`, para reemplazar el ícono genérico del sistema.
+
+La variante debug es independiente de la app productiva y puede instalarse para QA/presentación sin sobrescribir una instalación release histórica.
+
+## 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. unit tests 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.
+
+La barrera de lint exige además manejo explícito de la revocación de permisos de ubicación durante una captura GPS y declara la cámara como capacidad de hardware opcional, sin relajar permisos ni desactivar reglas globalmente.
+
+El artefacto de CI contiene:
+
+- APK debug;
+- archivo `.sha256`;
+- `release-metadata.txt` con fase, versión, versionCode, commit, applicationId, API base y canal.
+
+## Firma release
+
+La clave histórica de firma **no se versiona ni se reemplaza**. La CI compila la variante release para detectar roturas, pero la APK productiva final debe firmarse con la clave histórica antes de instalarse como actualización de `com.korexlabs.dhinspeccion`.
+
+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;
+- realizar actualización sobre al menos una tablet con la versión productiva anterior;
+- ejecutar smoke funcional contra el entorno objetivo: login, lista de inspecciones, inicio, inventario, alta de campo, foto/GPS, Acta, Hallazgo y cierre;
+- registrar el SHA Git y SHA-256 de la APK distribuida.
