1//! Module: traits

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