IAbsorbPresenter/IGrabPresenter/IMeleePresenter/IThrustPresenter let a Unity component declare which capability events it visualizes without knowing about CapabilityEvents itself. CapabilityPresentationBinder is the only thing that subscribes a presenter to its matching stream, resolving a GrabEvent's plain target handle to a live Transform (and initial velocity) through delegates its owner supplies, since the engine-free GrabEvent can't carry a Unity reference. Neither file knows about FieldDriver or any other concrete presentation. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
