### Repository Interfaces
- Always create interfaces in the domain layer (`repository.go`)
- Always create interfaces in the same package (`repository.go`)
- Use context.Context as first parameter for all methods
- Return domain entities, not database models
- Include common operations: Create, GetByID, Update, Delete, List
- Use specific query methods (e.g., `GetByEmail`, `GetByCompanyID`)
- Repository implementation is in the same file as the interface

- Use request/response forms for complex operations
- Include validation in service methods
- Handle business logic, not infrastructure concerns

)

## 🚀 Remember
- Prioritize simplicity and readability over cleverness
- Make code self-documenting through clear naming
- Always consider the person who will maintain this code
- Test your code thoroughly
- Security and performance are not optional
- Follow the established domain structure pattern
- **Follow the flat domain structure**: All files in a domain use the same package name
- Use the custom logger interface consistently
- Implement proper error handling and logging
- Follow the repository pattern with embedded implementations
- Follow the repository pattern with interface and implementation in same file
- **Time Consistency**: Always use Unix timestamps (int64) for input, storage, and output
- **Time Validation**: Validate all Unix timestamp inputs are within reasonable ranges
- **Time Utilities**: Use centralized time utility functions for consistency across the application

## 🚀 Remember
- Prioritize simplicity and readability over cleverness
- Make code self-documenting through clear naming
- Always consider the person who will maintain this code
- Test your code thoroughly
- Security and performance are not optional
- Follow the established domain structure pattern
- **Follow the flat domain structure**: All files in a domain use the same package name
- Use the custom logger interface consistently
- Implement proper error handling and logging
- Follow the repository pattern with embedded implementations
- Follow the repository pattern with interface and implementation in same file
- **Time Consistency**: Always use Unix timestamps (int64) for input, storage, and output
- **Time Validation**: Validate all Unix timestamp inputs are within reasonable ranges
- **Time Utilities**: Use centralized time utility functions for consistency across the application
@@ -836,3 +349,4 @@ func main() {
- **Validation**: Always use govalidator for request validation with proper tags
- **Form Design**: Define validation rules in request forms, not in handlers
- **Custom Validators**: Register custom validators for complex validation rules
- **Package Structure**: Keep all domain files in the same package for easy access and minimal imports
