## Photo Album Event Types

Captures these major life moments:
- 🎓 **Graduations** - High school, college, masters, PhD
- 💍 **Marriages** - Wedding events and anniversaries
- 👶 **Births** - Birth of children
- 💼 **Career** - Job promotions, first job, career milestones
- ⚰️ **Death** - End of life summaries
- 🤝 **Friendships** - Best friend milestones
- ❤️ **Dating** - Romantic relationship starts
- 🏆 **Achievements** - Major accomplishments

---

## Database Schema

Uses 3 tables from `migrations/001_monetization_and_retention.sql`:

1. **`player_statistics`** - Tracks 16 lifetime statistics
   - Indexed on `player_id`
   - Auto-updating timestamps

2. **`player_photo_album`** - Stores memorable moments
   - Indexed on `(player_id, game_date)` and `event_type`
   - JSON `snapshot_data` for flexible metadata

3. **`player_inventory`** - Item ownership tracking
   - Used by achievement system for collections

## Usage Examples

### Initialize New Player
```python
from retention.statistics import initialize_player_statistics
initialize_player_statistics(player_id)
```

### Track Statistics
```python
from retention.statistics import increment_stat, update_stat

# Increment a stat
increment_stat(player_id, 'total_activities', 1)
increment_stat(player_id, 'lifetime_earnings', 5000)

# Update max/highest stat
update_stat(player_id, 'highest_job_level', 5)

# Set boolean
set_boolean_stat(player_id, 'ever_married', True)
```

### Capture Photo Memory
```python
from retention.statistics import capture_photo_memory

capture_photo_memory(
    player_id=1,
    event_type='graduation',
    description='Graduated from Harvard University',
    snapshot_data={
        'level': 'college',
        'gpa': 3.8,
        'major': 'Computer Science'
    }
)
```

### Retrieve Data
```python
from retention.statistics import get_player_statistics, get_photo_album

# Get all statistics
stats = get_player_statistics(player_id)
# Returns: {'lifetime_earnings': 50000, 'total_deaths': 2, ...}

# Get photo album
photos = get_photo_album(player_id, limit=50)
# Returns: [{'event_type': 'graduation', 'description': '...', ...}, ...]
```
