+## Session 6: Extract road assembly module
+
+**Date**: 2026-08-03
+**Task**: Extract road assembly module
+**Branch**: `main`
+
+### Summary
+
+Moved Blender road GeoJSON assembly and OSM fallback roads into blender/osmassets/roads.py while preserving road_counts, Layer catalog warnings, scene metadata, and SCENE_DONE output. Verified py_compile, unittest, task validation, and Blender/Cesium parity before/after as identical for both sample areas.
