# ET-PROG-002: Implementación de Captura de Avances Físicos

**Épica:** MAI-005 - Control de Obra y Avances
**Módulo:** Captura de Avances
**Responsable Técnico:** Backend + Frontend + Mobile
**Fecha:** 2025-11-17
**Versión:** 1.0

---

## 1. Objetivo Técnico

Implementar el sistema de captura de avances físicos con:
- Registro de avances por porcentaje, cantidad o unidad
- Captura desde web y app móvil (modo offline)
- Flujo de aprobación de avances con validaciones
- Geolocalización automática de registros
- Actualización en tiempo real de Curva S
- Dashboard de productividad por cuadrilla

---

## 2. Stack Tecnológico

### Backend
```typescript
- NestJS 10+ con TypeScript
- TypeORM para PostgreSQL
- PostgreSQL 15+ (schema: progress)
- PostGIS para geolocalización
- EventEmitter2 para eventos
- Bull/BullMQ para procesamiento async
```

### Frontend Web
```typescript
- React 18 con TypeScript
- React Hook Form para formularios
- Zustand para state management
- React Query para cache y sync
- Leaflet para mapas
```

### Mobile App
```typescript
- React Native 0.72+
- Expo 49+ para geolocation
- SQLite para almacenamiento offline
- NetInfo para detección de conectividad
- react-native-camera para fotos
```
