 Added
 ^^^^^
 
-* Added :class:`~isaaclab.cloner.ClonePlan` as the single source of truth for
-  clone sources, destination templates, and the source-to-environment mask.
-* Added :meth:`~isaaclab.sim.SimulationContext.get_clone_plan` and
-  :meth:`~isaaclab.sim.SimulationContext.set_clone_plan` for publishing the
-  scene clone plan.
-* Added explicit ``spawn_paths`` support to multi-asset spawners so scene
-  planning can spawn representative heterogeneous sources directly.
+* Added :class:`~isaaclab.cloner.ClonePlan` frozen dataclass capturing per-group
+  prototype-to-environment mappings (``dest_template``, ``prototype_paths``,
+  ``clone_mask``). Lets downstream consumers (scene data providers, mesh samplers)
+  read prototype geometry once and scatter to environments via the per-group mask
+  instead of walking per-env USD paths.
+* Added :meth:`~isaaclab.sim.SimulationContext.get_clone_plans` and
+  :meth:`~isaaclab.sim.SimulationContext.set_clone_plans` for publishing and
+  consuming the cloner's per-group plan map.
+* Added :attr:`~isaaclab.scene.InteractiveScene.clone_plans` property (forwards to
+  :meth:`~isaaclab.sim.SimulationContext.get_clone_plans`) so consumers holding a
+  scene reference can read the published plans without going through the sim
+  context.
 
 Changed
 ^^^^^^^
 
-* **Breaking:** :class:`~isaaclab.scene.InteractiveScene` now builds clone plans
-  directly from asset configuration, spawns representative sources in their
-  selected environments, and replicates from those sources. This removes the old
-  template-spawn and prototype-discovery round trip.
-* **Breaking:** Replaced ``TemplateCloneCfg`` with
-  :class:`~isaaclab.cloner.CloneCfg` for clone execution settings.
-* Changed :func:`~isaaclab.cloner.make_clone_plan` to return a
-  :class:`~isaaclab.cloner.ClonePlan` object directly.
+* **Breaking:** :func:`~isaaclab.cloner.clone_from_template` now returns
+  ``dict[str, ClonePlan]`` instead of ``None``. Bind the result and publish it
+  through :meth:`~isaaclab.sim.SimulationContext.set_clone_plans` if downstream
+  consumers (e.g. the PhysX scene data provider's Newton-visualizer build path)
+  need to read the plan.
 
 Removed
 ^^^^^^^
 
-* **Breaking:** Removed :func:`~isaaclab.cloner.clone_from_template`. Use
-  :func:`~isaaclab.cloner.make_clone_plan`,
-  :func:`~isaaclab.cloner.usd_replicate`, and backend physics replication
-  functions for direct cloning workflows.
+* **Breaking:** Removed
+  :attr:`~isaaclab.cloner.TemplateCloneCfg.visualizer_clone_fn`,
+  :func:`~isaaclab.cloner.resolve_visualizer_clone_fn`, and
+  :class:`~isaaclab.physics.scene_data_requirements.VisualizerPrebuiltArtifacts`.
+  Scene data providers now build backend models from the
+  :class:`~isaaclab.cloner.ClonePlan` map via
+  :meth:`~isaaclab.sim.SimulationContext.get_clone_plans` instead of receiving a
+  prebuilt artifact through a clone-time callback.
+* **Breaking:** Removed
+  :meth:`~isaaclab.sim.SimulationContext.get_scene_data_visualizer_prebuilt_artifact`,
+  :meth:`~isaaclab.sim.SimulationContext.set_scene_data_visualizer_prebuilt_artifact`,
+  and
+  :meth:`~isaaclab.sim.SimulationContext.clear_scene_data_visualizer_prebuilt_artifact`.
+  Use :meth:`~isaaclab.sim.SimulationContext.get_clone_plans` /
+  :meth:`~isaaclab.sim.SimulationContext.set_clone_plans` instead.
