Summary

Review and consolidate factory classes in logger_system to simplify the codebase for C++20 module migration, following Kent Beck's "Fewest Elements" principle.

Problem Analysis

C++20 Module Impact

When converting to modules, factory classes add complexity to module boundaries:

export module kcenon.logger;
// Factories complicate the public API surface

Proposed Analysis Tasks

• Audit all factory classes for usage patterns
• Identify factories that can be replaced with builders
• Consolidate overlapping factory functionality
• Document remaining factories with clear purpose

Tasks

• Review di_container_factory usage and necessity
• Review monitoring_factory usage and necessity
• Identify unused or redundant factory methods
• Create consolidation plan
• Implement changes with deprecation warnings
• Update documentation

Acceptance Criteria

• All factory classes have clear, documented purpose
• No redundant factory implementations
• Factory patterns simplified for module conversion
• All tests pass
• No breaking changes to public API
