# Issue #015: Geolocation & Permissions

**Tipo**: Enhancement
**Prioridad**: Baja (Avanzado)
**Estado**: Pendiente

## Descripción

Implementar sistema para configurar geolocation y permisos del navegador (notifications, geolocation, camera, mic, etc.).

## Funcionalidad deseada

### Geolocation
- Establecer coordenadas GPS personalizadas
- Simular precisión de GPS
- Cambiar ubicación dinámicamente

### Permissions
- Otorgar/denegar permisos específicos
- Permisos por origen (URL)
- Lista completa de permisos soportados

## API propuesta

```go
type Geolocation struct {
    Latitude  float64
    Longitude float64
    Accuracy  float64 // En metros
}

type Permission string
const (
    PermissionGeolocation      Permission = "geolocation"
    PermissionNotifications    Permission = "notifications"
    PermissionCamera           Permission = "videoCapture"
    PermissionMicrophone       Permission = "audioCapture"
    PermissionClipboard        Permission = "clipboardReadWrite"
    PermissionMIDI             Permission = "midi"
    PermissionBackgroundSync   Permission = "backgroundSync"
    PermissionPersistentStorage Permission = "persistentStorage"
)

func (b *Browser) SetGeolocation(ctx context.Context, geo *Geolocation) error
func (b *Browser) ClearGeolocation(ctx context.Context) error
func (b *Browser) GrantPermissions(ctx context.Context, origin string, permissions []Permission) error
func (b *Browser) DenyPermissions(ctx context.Context, origin string, permissions []Permission) error
func (b *Browser) ResetPermissions(ctx context.Context) error
```

## Uso

### Establecer ubicación
```go
// Simular estar en Nueva York
b.SetGeolocation(ctx, &browser.Geolocation{
    Latitude:  40.7128,
    Longitude: -74.0060,
    Accuracy:  10, // 10 metros
})

b.Navigate(ctx, "https://maps.google.com", nil)
```

### Otorgar permisos
```go
// Permitir notifications y geolocation
b.GrantPermissions(ctx, "https://example.com", []browser.Permission{
    browser.PermissionNotifications,
    browser.PermissionGeolocation,
})

b.Navigate(ctx, "https://example.com", nil)
```

### Denegar cámara/micrófono
```go
b.DenyPermissions(ctx, "https://videocall.com", []browser.Permission{
    browser.PermissionCamera,
    browser.PermissionMicrophone,
})
```

### Cambiar ubicación dinámicamente
```go
// Simular movimiento
locations := []browser.Geolocation{
    {Latitude: 40.7128, Longitude: -74.0060}, // NYC
    {Latitude: 34.0522, Longitude: -118.2437}, // LA
    {Latitude: 41.8781, Longitude: -87.6298},  // Chicago
}

for _, loc := range locations {
    b.SetGeolocation(ctx, &loc)
    time.Sleep(5 * time.Second)
}
```

## CDP Methods

### Geolocation
```go
// Establecer
{"method": "Emulation.setGeolocationOverride", "params": {
    "latitude": 40.7128,
    "longitude": -74.0060,
    "accuracy": 10
}}

// Limpiar
{"method": "Emulation.clearGeolocationOverride"}
```

### Permissions
```go
// Otorgar
{"method": "Browser.grantPermissions", "params": {
    "origin": "https://example.com",
    "permissions": ["geolocation", "notifications"]
}}

// Denegar (remover)
{"method": "Browser.resetPermissions"}
```

## Permisos disponibles

| Permission | Descripción |
|-----------|-------------|
| `geolocation` | Acceso a GPS |
| `notifications` | Push notifications |
| `videoCapture` | Cámara |
| `audioCapture` | Micrófono |
| `clipboardReadWrite` | Clipboard |
| `midi` | MIDI devices |
| `backgroundSync` | Background sync |
| `persistentStorage` | Persistent storage |

## Casos de uso

### Testing de apps con geolocation
```go
// Test en diferentes ciudades
cities := map[string]browser.Geolocation{
    "NYC": {40.7128, -74.0060, 10},
    "LA":  {34.0522, -118.2437, 10},
}

for name, loc := range cities {
    b.SetGeolocation(ctx, &loc)
    b.Navigate(ctx, "https://app.com/nearby", nil)
    // Verificar resultados específicos de ciudad
}
```

### Testing sin permisos
```go
// Simular usuario que deniega permisos
b.DenyPermissions(ctx, "https://app.com", []browser.Permission{
    browser.PermissionCamera,
})

b.Navigate(ctx, "https://app.com/video-call", nil)
// Verificar que app maneja correctamente el error
```
