We follow strict coding standards to ensure quality and consistency. See Coding Standards for details.

Key principles:

• Explicit error handling (no catch unreachable)
• Comprehensive documentation
• Platform abstraction
• Performance-first design

The codebase has undergone significant refactoring:

• ✅ Consolidated duplicate math modules
• ✅ Implemented proper error handling
• ✅ Added Windows platform support
• ✅ Created comprehensive documentation

See Refactoring Roadmap for details.
