//! Integration with the inventory crate for compile-time registration.

//! Provides utilities for working with inventory-collected components.

//! Revision History
//! - 2025-10-02T00:00:00Z @AI: Initial inventory integration.

  /// (the registry is link-time-fixed), so two iterations yield the same count. (The old
  /// assertion `len() >= 0` was vacuous.)
