Showcase

This section provides three realistic integration showcases. Each example targets a different use case so you can adapt the pattern that best matches your library.

Example Catalog

Showcase	What you will find
Optional Backend Routing	Conditional dependency enforcement with @dep_digest(..., when=...) and lazy imports for backend-specific execution paths.
Plugin Ecosystem with LazyRegistry	A scalable plugin architecture where discovery is cheap and optional plugin dependencies are enforced only on access.
User-Facing Dependency Diagnostics	A practical pattern to expose dependency status to end users (CLI/notebook/support workflows) using introspection APIs.
