//! Stable logical identity for a managed artifact.
//!
//! An `Artifact` is a uniquely identifiable logical piece of content or
//! produced output that can be referenced, versioned, validated, accessed,
//! and associated with provenance.
//!
//! It does not own artifact content, versions, storage, or lifecycle state.
//! It represents only the stable logical identity of the artifact.

/// represented by separate Phase 10 mechanisms.
