+## Session 39: Complete native-only pipeline replacement
+
+**Date**: 2026-08-18
+**Task**: Complete native-only pipeline replacement
+**Branch**: `feature/native-road-compiler`
+
+### Summary
+
+Made native road compilation the default provider and full-build stage set; decoupled package traffic signals and preview from QGIS/osm2streets, made diagnostics provider-aware, updated docs/specs/tests, and preserved explicit legacy reference/debug paths. Native road compile/check and all available Node tests passed. QGIS baseline remains tagged qgis-original-baseline-20260818.
