Event Handler

Event Handler System

The event-handler subsystem resolves a Gameplay Tag to a handler class derived from the Core handler base.

Lifecycle modes

• Ephemeral: create for one execution.
• Cached: reuse an instance while it remains cached.
• Singleton: maintain one shared instance for the configured scope.

Handlers can be registered and inspected through Core contracts. They are a behavior-dispatch mechanism, distinct from broadcasting a typed message to multiple listeners.

Use handlers when a tag selects an implementation. Use messages when a publisher announces data to optional receivers.
