• Type-safe mappings: Template-based member binding
• Mock database: In-memory testing backend

Key Features

• Compile-time schema validation using C++20 concepts
• Type-safe database mappings with template specialization
• Zero runtime overhead through constexpr mappings
• Mock database integration for testing
