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).

GrabEvent carries a FloatingBodyId; Zone gains TryHold/SetHeldProgress/Free and places a held item instead of
integrating it; Entity.TractorPower is derived from Pickup.Power and TractorCommand is the pilot's input
(ActionGameManager writes it undamped, the Time.deltaTime ramp is deleted). Binder and FieldTester change the
delegate type only. PickupTests and a save round-trip pin for the player's zone index.
Group A builds; no beam is on any generated ship until group B.

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.
