### 📚 Documentation Updates

#### New Guides
- **Complete workflow**: Requirements → Specification → Implementation → Deployment
- **Troubleshooting**: Real-world issues and solutions
- **Best practices**: Environment-specific development patterns
- **Migration guide**: v6 → v7 upgrade path

#### Enhanced Examples
- **Guesthouse booking system**: Complete working example
- **Data consistency patterns**: snake_case/camelCase mapping
- **Error handling**: Comprehensive error scenarios
- **Environment scaling**: Dev/Prod configuration differences

### 🔄 Migration from v6

#### Breaking Changes
1. **Materialise prompt**: New data consistency variables required
2. **Realize prompt**: Environment-specific template logic
3. **File paths**: Updated to `prompts/core/standard/v7/`

#### Upgrade Steps
1. Update prompt file paths to v7 directory
2. Add new variables for data consistency and environment type
3. Review generated output for enhanced error handling
4. Test environment-adaptive deployment configurations

### 🐛 Bug Fixes from Real Implementation

#### Data Layer Issues (Fixed in v7)
- **Fixed**: Database column mapping (room_id vs roomId)
- **Fixed**: Date format conversion (ISO strings vs YYYY-MM-DD)
- **Fixed**: API response transformation consistency
- **Fixed**: Missing data validation at model boundaries

#### Deployment Issues (Fixed in v7)
- **Fixed**: Environment variable loading in setup scripts
- **Fixed**: Database connection handling in development
- **Fixed**: Missing health checks and monitoring
- **Fixed**: Over-engineering for simple development environments

#### Developer Experience (Enhanced in v7)
- **Added**: Quick start scripts (start.sh) for immediate productivity
- **Added**: Comprehensive error messages and debugging
- **Added**: Environment-specific documentation
- **Added**: Real troubleshooting scenarios

### 🎯 Key Lessons Learned

1. **Data consistency is critical**: v7 emphasizes proper data mapping
2. **Environment matters**: Different environments need different complexity
3. **Automation saves time**: Setup scripts reduce friction significantly
4. **Error handling is essential**: Comprehensive patterns prevent issues
5. **Local dev parity**: Development should match production patterns
