//! Module: nns::topology::report::registry_versions
//!
//! Responsibility: project shared component Registry provenance into topology rows.
//! Does not own: component collection, relation joins, or text rendering.
//! Boundary: keeps inventory and Subnet-catalog provenance consistent across views.
