+## Session 7: Add feature registry dispatch
+
+**Date**: 2026-08-03
+**Task**: Add feature registry dispatch
+**Branch**: `main`
+
+### Summary
+
+Introduced blender/osmassets/features.py with FeatureHandler and dispatch_ways for ordered OSM way feature dispatch. Converted generate_scene.py water/grass/scrub/tree_row/building branches into registry handlers while keeping material order, counts, road warning behavior, scene metadata, and SCENE_DONE unchanged. Verified py_compile, unittest, task validation, and Blender/Cesium parity before/after as identical for both sample areas.
