## Directivas Obligatorias

### 1. Herencia de Componentes Core
```typescript
// OBLIGATORIO: Importar componentes base de core
import { Button, Input, Modal } from '@erp-core/ui';
import { DataTable } from '@erp-core/components';
import { useAuth, useTenant } from '@erp-core/hooks';
```

### 2. Multi-Tenant Context
```typescript
// OBLIGATORIO: Usar contexto de tenant
const { tenantId, tenantName } = useTenant();

// Todas las llamadas API deben incluir tenant
const response = await api.get('/projects', {
  headers: { 'X-Tenant-Id': tenantId }
});
```

### 3. Mobile-First para Campo
```typescript
// Módulos de campo (avances, inspecciones) deben ser mobile-first
// Usar breakpoints: sm (640px), md (768px), lg (1024px)
```

### Store con Zustand
```typescript
import { create } from 'zustand';
import { devtools, persist } from 'zustand/middleware';
import { Project, ProjectFilters } from '@/types/project.types';

interface ProjectState {
  // State
  projects: Project[];
  selectedProject: Project | null;
  filters: ProjectFilters;
  isLoading: boolean;
  error: string | null;

  // Actions
  setProjects: (projects: Project[]) => void;
  selectProject: (project: Project | null) => void;
  setFilters: (filters: Partial<ProjectFilters>) => void;
  setLoading: (isLoading: boolean) => void;
  setError: (error: string | null) => void;
  reset: () => void;
}

const initialState = {
  projects: [],
  selectedProject: null,
  filters: { status: 'ALL' as const, search: '' },
  isLoading: false,
  error: null,
};

export const useProjectStore = create<ProjectState>()(
  devtools(
    persist(
      (set) => ({

## Componentes Mobile (React Native patterns)

```typescript

  const { projectId, unitId, conceptId } = route.params;
  const [photos, setPhotos] = useState<string[]>([]);

  const { control, handleSubmit } = useForm({
    defaultValues: {
      progress: 0,
      notes: '',
    },
  });

  const takePhoto = async () => {
    const result = await ImagePicker.launchCameraAsync({
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
      quality: 0.7,
    });

    if (!result.canceled) {
      setPhotos([...photos, result.assets[0].uri]);
    }
  };

  const onSubmit = async (data) => {
    // Submit con fotos
    await progressService.register({
      ...data,
      projectId,
      unitId,
      conceptId,
      photos,
    });
    navigation.goBack();
  };

  return (
    <ScrollView className="flex-1 bg-white p-4">
      <Text className="text-lg font-bold mb-4">Registrar Avance</Text>

      <Controller
