## Permanent Rules Established
**CREATED**: `cline_docs/permanent_rules.md` - Permanent development rules that must be followed in all future work.

**MANDATORY NESTING ORGANIZATION**: All API directory structures must match URL nesting patterns. No exceptions.

**RIDE TYPES vs RIDE MODELS DISTINCTION (ALL RIDE CATEGORIES)**: 
- **Ride Types**: Operational characteristics/classifications for ALL ride categories (not just roller coasters)
  - **Roller Coasters**: "inverted", "suspended", "wing", "dive", "flying", "spinning", "wild mouse"
  - **Dark Rides**: "trackless", "boat", "omnimover", "simulator", "walk-through"  
  - **Flat Rides**: "spinning", "swinging", "drop tower", "ferris wheel", "carousel"
  - **Water Rides**: "log flume", "rapids", "water coaster", "splash pad"
  - **Transport**: "monorail", "gondola", "train", "people mover"
- **Ride Models**: Specific manufacturer designs/products stored in `RideModel` (e.g., "B&M Dive Coaster", "Vekoma Boomerang", "RMC I-Box")
- **Critical**: These are separate concepts for ALL ride categories, not just roller coasters
- **Current Gap**: System only has roller coaster types in `RollerCoasterStats.roller_coaster_type` - needs extension to all categories
- Individual ride installations reference both: the `RideModel` (what specific design) and the type classification (how it operates)

## Next Steps
1. **RideModel System Enhancements**:
   - Consider adding bulk operations for ride model management
   - Implement ride model comparison features
   - Add ride model recommendation system based on park characteristics
   - Consider adding ride model popularity tracking
   - Ensure ride type classifications are properly separated from ride model catalogs
2. **Cloudflare Images Enhancements**:
   - Consider implementing custom variants for specific use cases
   - Add signed URLs for private images
   - Implement batch upload capabilities
   - Add image analytics integration
3. **Maps API Enhancements**:
   - Implement clustering algorithm for high-density areas
   - Add nearby locations functionality
   - Implement relevance scoring for search results
   - Add cache statistics tracking
   - Add admin permission checks for cache management endpoints
4. **Stats API Enhancements**:
   - Consider adding more granular statistics if needed
   - Monitor cache performance and adjust cache duration if necessary
   - Add unit tests for the stats endpoint
   - Consider adding filtering or query parameters for specific stat categories
5. **Testing**: Add comprehensive unit tests for all endpoints
6. **Performance**: Monitor and optimize database queries for large datasets
