//! Module: traits

//! Responsibility: foundational kind, field metadata, and projection
//! contracts awaiting narrower domain ownership.
//! Does not own: entity composition, key taxonomy, runtime value conversion,
//! visitor traversal, executor policy, or public facade DTO behavior.
//! Boundary: remaining reusable contracts consumed throughout `icydb-core`.
