IGrabPresenter.Grab(GrabEvent) only; the binder's Transform and velocity resolvers go. TractorBeam presents a running grab (aims at Started's TargetPosition, emits at Power, dark otherwise). FieldDriver draws its tendril from GrabEvents alone with a real-time phase clock over each event's PhaseDuration and writes no transform and destroys nothing; its grab times move to FieldTester, now the scene's stand-in sim that owns its pickup's timeline and pose. ItemPickup keeps its label lit while held. ImpactPresenterSmoke becomes CapabilityPresentationSmoke with a grab section; its two untracked-ship expectations follow DrawsAt since contact-hud. Builds (Unity 6000.3.24f1 batchmode: smoke ok, scene opens, no missing script). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
