+Added
+^^^^^
+
+* Added MuJoCo tendon parsing to Newton physics replication.
+  :func:`~isaaclab_newton.cloner.newton_replicate._build_newton_builder_from_mapping`
+  now includes :class:`SchemaResolverMjc` in its resolver list and calls
+  ``SolverMuJoCo.register_custom_attributes`` on the main builder so that
+  ``MjcTendon`` prims (e.g. Shadow Hand fixed tendons) are included in the
+  replicated Newton model.
+
+Fixed
+^^^^^
+
+* Fixed MuJoCo tendon duplication in Newton physics replication where
+  :func:`~isaaclab_newton.cloner.newton_replicate._build_newton_builder_from_mapping`
+  called ``add_builder`` once per environment, causing each call to append
+  tendon custom-attribute entries and resulting in N×T total entries instead of
+  the expected T. Added :func:`~isaaclab_newton.cloner.newton_replicate._deduplicate_tendon_attributes`
+  to trim all ``mujoco:tendon*`` lists to the world-0 count after the build loop.
