+# Issues and Technical Debt Documentation
+
+## Known Bugs
+
+### 1. Data Integrity Issues
+
+#### Historical Slug Resolution
+```python
+# Current Implementation
+class Park(models.Model):
+    @classmethod
+    def get_by_slug(cls, slug: str):
+        # Issue: Race condition possible between slug check and retrieval
+        # TODO: Implement proper locking or transaction handling
+        try:
+            return cls.objects.get(slug=slug)
+        except cls.DoesNotExist:
+            return cls.objects.get(historical_slugs__slug=slug)
+```
+
+#### Media File Management
+```python
+# Current Issue
+class MediaHandler:
+    def process_upload(self, file):
+        # Bug: Temporary files not always cleaned up
+        # TODO: Implement proper cleanup in finally block
+        try:
+            process_file(file)
+        except Exception:
+            log_error()
+```
+
+### 2. Performance Issues
+
+#### N+1 Query Patterns
+```python
+# Inefficient Queries in Views
+class ParkDetailView(DetailView):
+    def get_context_data(self):
+        context = super().get_context_data()
+        # Issue: N+1 queries for each ride's reviews
+        context['rides'] = [
+            {
+                'ride': ride,
+                'reviews': ride.reviews.all()  # Causes N+1 query
+            } 
+            for ride in self.object.rides.all()
+        ]
+```
+
+#### Cache Invalidation
+```python
+# Inconsistent Cache Updates
+class ReviewManager:
+    def update_stats(self, obj):
+        # Bug: Race condition in cache updates
+        # TODO: Implement atomic cache updates
+        stats = calculate_stats(obj)
+        cache.set(f'{obj}_stats', stats)
+```
+
+## Technical Debt
+
+### 1. Code Organization
+
+#### Monolithic Views
+```python
+# views.py
+class ParkView(View):
+    def post(self, request, *args, **kwargs):
+        # TODO: Break down into smaller, focused views
+        # Currently handles too many responsibilities:
+        # - Park creation
+        # - Media processing
+        # - Notification sending
+        # - Stats updating
+```
+
+#### Duplicate Business Logic
+```python
+# Multiple implementations of similar functionality
+class ParkValidator:
+    def validate_status(self):
+        # TODO: Consolidate with RideValidator.validate_status
+        if self.status not in VALID_STATUSES:
+            raise ValidationError()
+
+class RideValidator:
+    def validate_status(self):
+        if self.status not in VALID_STATUSES:
+            raise ValidationError()
+```
+
+### 2. Infrastructure
+
+#### Configuration Management
+```python
+# settings.py
+# TODO: Move to environment variables
+DATABASE_PASSWORD = 'hardcoded_password'
+API_KEY = 'hardcoded_key'
+
+# TODO: Implement proper configuration management
+FEATURE_FLAGS = {
+    'new_review_system': True,
+    'beta_features': False
+}
+```
+
+#### Deployment Process
+```bash
+# Manual deployment steps
+# TODO: Automate deployment process
+ssh server
+git pull
+pip install -r requirements.txt
+python manage.py migrate
+supervisorctl restart app
+```
+
+### 3. Testing
+
+#### Test Coverage Gaps
+```python
+# Missing test cases for error conditions
+class ParkTests(TestCase):
+    def test_create_park(self):
+        # Only tests happy path
+        park = Park.objects.create(name='Test Park')
+        self.assertEqual(park.name, 'Test Park')
+        
+    # TODO: Add tests for:
+    # - Invalid input handling
+    # - Concurrent modifications
+    # - Edge cases
+```
+
+#### Integration Test Debt
+```python
+# Brittle integration tests
+class APITests(TestCase):
+    # TODO: Replace with proper test doubles
+    def setUp(self):
+        # Direct database dependencies
+        self.park = Park.objects.create()
+        # External service calls
+        self.geocoder = RealGeocoder()
+```
+
+## Enhancement Opportunities
+
+### 1. Feature Enhancements
+
+#### Advanced Search
+```python
+# Current basic search implementation
+class ParkSearch:
+    def search(self, query):
+        # TODO: Implement advanced search features:
+        # - Full-text search
+        # - Faceted search
+        # - Geographic search
+        return Park.objects.filter(name__icontains=query)
+```
+
+#### Review System
+```python
+# Basic review functionality
+class Review(models.Model):
+    # TODO: Enhance with:
+    # - Rich text support
+    # - Media attachments
+    # - Review responses
+    # - Helpful votes
+    rating = models.IntegerField()
+    comment = models.TextField()
+```
+
+### 2. Technical Improvements
+
+#### API Versioning
+```python
+# Current API structure
+# TODO: Implement proper API versioning
+urlpatterns = [
+    path('api/parks/', ParkViewSet.as_view()),
+    # Need to support:
+    # - Multiple versions
+    # - Deprecation handling
+    # - Documentation
+]
+```
+
+#### Caching Strategy
+```python
+# Basic caching
+# TODO: Implement:
+# - Multi-layer caching
+# - Cache warming
+# - Intelligent invalidation
+@cache_page(60 * 15)
+def park_detail(request, slug):
+    return render(request, 'park_detail.html')
+```
+
+### 3. Performance Optimizations
+
+#### Database Optimization
+```python
+# Current database usage
+# TODO: Implement:
+# - Connection pooling
+# - Read replicas
+# - Query optimization
+DATABASES = {
+    'default': {
+        'ENGINE': 'django.db.backends.postgresql',
+        'NAME': 'thrillwiki',
+    }
+}
+```
+
+#### Asset Delivery
+```python
+# Static file handling
+# TODO: Implement:
+# - CDN integration
+# - Image optimization pipeline
+# - Responsive images
+STATIC_URL = '/static/'
+MEDIA_URL = '/media/'
+```
