+# norm_stats points at THIS checkpoint's own statistics (the file shipped beside this
+# one). It must stay present even when a loader passes an explicit path: LingBot's
+# FeatureTransform does `robot_config.pop('norm_stats')` with no default on both
+# branches, so a missing key raises KeyError. The path is relative to this checkpoint's
+# root -- resolve it yourself, or pass an absolute `norm_stats_path`
+# (maniguard/serve/lingbot_native.py does the latter).
