# Implementation Plan
|
|
|
|
1. Extend the native OSM parse/model with marked crossing-node evidence while
|
|
preserving existing road IDs and parser behavior.
|
|
2. Add native crossing clustering, tangent resolution from directed lane
|
|
centerlines, stripe geometry, safe stop-line placement, and source
|
|
diagnostics.
|
|
3. Persist the two new layers in `compile-native-roads.js`, comparison counts,
|
|
native build records, required native layer checks, and existing Blender
|
|
material mappings.
|
|
4. Add Workbench API/state fields, Chinese layer toggles, selection evidence,
|
|
and summary counts while retaining scene-preview behavior.
|
|
5. Add focused fixtures for marked and unmarked crossings, duplicate cluster
|
|
handling, a missing native-lane diagnostic, and output layer contracts.
|
|
6. Run native/unit/workbench/build-stage tests, compile/check Nantaizi, then
|
|
build `blender,cesium,preview --road-provider native` without `package/`.
|
|
|
|
## Validation
|
|
|
|
```bash
|
|
npm run test:native-road
|
|
npm run test:road-workbench
|
|
npm run test:build-stages
|
|
npm run road:compile -- --config config/areas/nantaizi-lake-innovation-valley.json
|
|
npm run road:check -- --config config/areas/nantaizi-lake-innovation-valley.json
|
|
npm run build:area -- --config config/areas/nantaizi-lake-innovation-valley.json \
|
|
--stages blender,cesium,preview --road-provider native
|
|
```
|
|
|
|
Rollback is selecting `--road-provider osm2streets`; no legacy output path is
|
|
changed.
