"""
Core Package - Business Logic and Domain Models

This package contains the core business logic and domain models for the retrieval system.
It focuses on the essential functionality without infrastructure concerns.

Architecture:
- models.py: Core data models, business entities, and task definitions
- types.py: Domain-specific types and interfaces
- exceptions.py: Business-specific exceptions
- enums.py: Domain enumerations

Design Principles:
- Single Responsibility: Each module has a clear business purpose
- Dependency Inversion: Depends on abstractions, not implementations
- Domain-Driven Design: Reflects business concepts and rules
