A plugin architecture is a software design that lets an application's behavior be extended after it has shipped without modifying any existing code, including its imports. It combines a factory pattern — a registry mapping type identifiers to creator functions with `register`/`unregister`/`create` operations — with dynamic module loading (via `importlib`) that imports code by name at runtime and invokes a defined entry-point method to let the newly loaded module register itself with the factory. This belongs to the domain of software architecture and extensibility design in Python, relying on structural typing (Protocol classes) so that dynamically loaded types need not inherit from a common base class.
