 # Animation Runtime Crib
 
+## Current live presentation ownership (2026-07-21)
+
+`LiveEntityAnimationScheduler` owns ordinary-object time, PartArray advance,
+root motion, and the retail manager tail. `RetailStaticAnimatingObjectScheduler`
+owns the separate retail static-object workset. `LiveEntityAnimationPresenter`
+is the sole consumer that composes final drawable part transforms, publishes
+rigid part/effect poses, and binds `MotionDone`. `GameWindow` wires these owners
+but no longer contains the presentation body.
+
+The frame handoff is identity- and lifetime-bound. A schedule carries the exact
+`LiveEntityRecord`, `WorldEntity`, animation state, sequencer, object-clock
+epoch, projection mutation version, and presentation revision. Both ordinary
+and static schedulers copy the sequencer's borrowed PartArray view into their
+own buffers before invoking callbacks. Presentation is non-reentrant because
+it consumes legacy elapsed time and static prepared frames exactly once.
+
+Appearance rebinding increments `PresentationRevision`. That rejects a pose
+prepared against the old part template without replacing the live animation
+component. For a static owner, rejecting only that stale visual pose must retain
+the same sequencer's pending `process_hooks` tail so `MotionDone` is not lost;
+owner, sequencer, residency, projection, or clock mismatches still invalidate
+the entire handoff.
+
+Retail `CPartArray::UpdateParts` updates only the authored AnimFrame prefix.
+When a frame contains fewer parts than the Setup, trailing parts keep their
+previous pose (or their rest pose on first presentation) in both channels:
+
+- visual: `DefaultScale * rotation * translation(origin) * ObjScale`;
+- rigid/effect: `rotation * translation(origin * ObjScale)`.
+
+Canonical per-frame order remains scheduler tick, static tick, live presenter,
+equipped-child update, static `process_hooks`, deferred hook drain, attached
+effects/lights, particles, and draw. The end-to-end order assertion belongs to
+Slice 6's extracted update orchestrator; do not reintroduce local ordering into
+the presenter.
