+生成 `crosswalks.geojson` 和 `vehicle_stop_lines.geojson`。这是原生道路的独立
+产物，禁止读取 osm2streets 的渲染图层作为几何输入。
+
+### 2. 调用形式
+
+```bash
+npm run road:compile -- --config config/areas/nantaizi-lake-innovation-valley.json
+npm run road:workbench -- --config config/areas/nantaizi-lake-innovation-valley.json
+```
+
+工作台 `GET /api/state` 通过 `layers.crosswalks` 和
+`layers.vehicleStopLines` 返回两个 FeatureCollection。
+
+### 3. 契约
+
+- 只有 `highway=crossing` 且 `crossing:markings` 不是 `no`、`none` 或
+  `unmarked` 的 OSM 节点可以生成斑马线。每个安全匹配点生成六条 stripe，带
+  `crossing_node_id`、`road_id`、`lane_id`、`osm_way_ids`、`direction`、
+  `placement_method` 和 `native-road-crosswalk/v1` provenance。
+- 停止线还必须对应一个启用的 native arrival endpoint，且过街节点位于该进口到
+  路口的安全距离内；其 provenance 是 `native-road-stop-line/v1`。不能确认进口
+  时保留斑马线并写 `crossing-no-safe-stop-line` diagnostic，不得猜测一条线。
+- `catalog.NATIVE_ROAD_LAYERS` 将两个源层映射到现有的 `crosswalks` 和
+  `vehicle_stop_lines` 材质层。不得把它们加入 legacy `SCENE_LAYERS`。
+- 控制标线优先于箭头：默认直行箭头与其相交时跳过；路口转向箭头依次尝试在距路口
+  6、10、14、18、22 米处放置，均冲突时记录 `turn-arrow-control-conflict`。
+
+### 4. 校验与错误矩阵
+
+| 条件 | 结果 |
+|---|---|
+| 标记过街没有可匹配 native lane | `crossing-no-native-lane`，不生成任何控制标线 |
+| 有横道但没有安全进口方向 | 生成斑马线，记录 `crossing-no-safe-stop-line`，不生成停止线 |
+| 箭头与任一控制标线相交 | 直行箭头跳过；转向箭头后移或记录冲突 diagnostic |
+| native Blender 输入缺任一控制图层 | `ensureNativeRoadLayers()` 在启动 Blender 前失败 |
+
+### 5. 正常、基础与错误示例
+
+- 正常：一个靠近路口的 marked crossing 生成 6 条斑马线和 1 条进口停止线。
+- 基础：一条孤立的 marked crossing 可以生成斑马线，但不能凭邻近道路方向臆造停止线。
+- 错误：先生成箭头再叠加停止线，导致两者重叠；控制标线是道路控制语义，必须优先。
+
+### 6. 必需测试
+
+- `npm run test:native-road`：断言 marked / unmarked / 无 native lane 的输出，停止线的
+  provenance，以及箭头遇控制标线时后移。
+- `npm run test:road-workbench`：断言 controls 开关、两条 API layer 和中文选中溯源。
+- `npm run road:compile -- --config config/areas/nantaizi-lake-innovation-valley.json`：核查两层
+  feature count 及每条停止线都是 native arrival direction。
+- `npm run build:area -- --config config/areas/nantaizi-lake-innovation-valley.json --stages blender,cesium,preview --road-provider native`：不运行 `package`。
+
+### 7. 错误与正确写法
+
+错误：以最近任意方向车道和固定正向偏移生成停止线。
+
+```js
+const stopCenter = offsetByMeters(nearestLane.point, nearestLane.axis, 2.7);
+```
+
+正确：先确认该方向的终点是一个已启用的路口 arrival，再在人行横道的上游生成停止线。
+
+```js
+const approach = candidates.find((item) => arrivalEndpointIds.has(`endpoint:${item.road.id}:end`));
+const stopCenter = offsetByMeters(laneCenterAtCrossing, approach.placement.axis, -2.7);

+# Native Road Control Markings Design
+
+## Architecture
+
+The native compiler remains the source of truth. It extends its canonical OSM
+parse with marked crossing nodes, then derives two additive polygon layers from
+the crossing evidence, native directed lanes, and native junction plans:
+
+```text
+OSM crossing node + native directed lane centerlines + junction plans
+    |
+    +-- crosswalks.geojson: six zebra stripe polygons per safe crossing
+    |
+    +-- vehicle_stop_lines.geojson: one safe approach stop-line polygon
+```
+
+No osm2streets GeoJSON is read. Existing crossing geometry helpers may be
+extracted or adapted only when they operate on native lane data and retain
+native provenance.
+
+## Source And Placement
+
+- A source node is eligible only when `highway=crossing` and
+  `crossing:markings` is not `no`, `none`, or `unmarked`.
+- The compiler finds native roads containing the crossing's OSM node and uses
+  the nearest compatible directed lane centerline to obtain the road tangent.
+- Crosswalk stripes are perpendicular to that tangent and constrained to the
+  native road width. Existing fixed zebra dimensions are retained initially:
+  six 0.45m stripes with 0.45m gaps, 0.45m stripe width, and a highway-based
+  stripe length.
+- A stop line is generated only when the crossing can be associated with a
+  supported junction approach and a safe outside-of-junction side. Otherwise
+  the crosswalk may remain valid but the missing stop line is diagnostic.
+- Duplicate nearby crossing nodes use a stable cluster representative so one
+  physical crosswalk does not produce duplicate stripes.
+
+## Contracts
+
+`layers/crosswalks.geojson` and `layers/vehicle_stop_lines.geojson` are Polygon
+FeatureCollections. Each feature records its crossing OSM node, source OSM way,
+native directed road/lane when available, direction, placement method, and
+`native-road-crosswalk/v1` or `native-road-stop-line/v1` provenance.
+
+The Workbench API returns both layers as `state.layers.crosswalks` and
+`state.layers.vehicleStopLines`. Its browser map uses separate toggleable
+layers and selection evidence; the scene-preview toggle leaves real control
+markings visible.
+
+`catalog.NATIVE_ROAD_LAYERS` maps the sources to existing `crosswalks` and
+`vehicle_stop_lines` material layers. This native adapter must not add them to
+the osm2streets `ROAD_LAYERS` / `SCENE_LAYERS` registry.
+
+## Compatibility And Rollback
+
+The new files are additive under `native-road/layers/`. Existing osm2streets
+output and QGIS input are unchanged. Selecting `--road-provider osm2streets`
+remains rollback. A native Blender build treats a missing new layer as an error
+rather than silently omitting a visible marking.
+
+## Risks
+
+- Crossing nodes can be detached from a routable road or lie on an ambiguous
+  multi-road segment. These become diagnostics rather than guessed geometry.
+- A physical crossing split into several OSM nodes must deduplicate stably.
+- A crosswalk near a non-supported junction may get stripes but no valid stop
+  line; this difference must be exposed in workbench provenance.

+# 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.

+# Native road control markings
+
+## Goal
+
+Give Nantaizi's native-road provider inspectable, source-traceable crosswalk
+and vehicle stop-line geometry, so intersection control markings do not depend
+on the osm2streets render output.
+
+## Confirmed Facts
+
+- Native road output already owns road surfaces, sidewalks, lane separators,
+  repeated direction arrows, and explicit junction-turn arrows.
+- Nantaizi's OSM input contains explicit marked crossings, including zebra and
+  traffic-signal crossings. The existing osm2streets output currently has 48
+  crosswalk-stripe polygons and 8 stop-line polygons.
+- `build-osm2streets-qgis.js:1067` derives these markings from crossing nodes
+  plus osm2streets driving lanes. Native must not read that rendered geometry;
+  it can reuse only the tested geometry rules after adapting them to native
+  directed lanes and junction plans.
+- Existing Blender materials already provide `crosswalks` and
+  `vehicle_stop_lines`; native may map into them without changing the legacy
+  osm2streets layer registry.
+
+## Requirements
+
+- R1: Native compilation uses explicit marked OSM crossing nodes only, and
+  emits crosswalk-stripe polygons plus approach stop lines only where safe
+  native directed-road placement exists.
+- R2: Each generated feature preserves crossing node, OSM road, native road or
+  lane, direction, placement method, and relevant junction provenance.
+- R3: The Road Workbench independently toggles, selects, and describes native
+  crosswalks and stop lines in Chinese.
+- R4: Native Blender and Cesium builds consume both layers with the existing
+  control-marking materials; no `package/` publication is part of validation.
+- R5: Missing compatible road context, ambiguous geometry, and unsupported
+  crossing inputs are diagnostics; the compiler must not invent a crossing.
+
+## Acceptance Criteria
+
+- [ ] Nantaizi native output contains valid `crosswalks.geojson` and
+  `vehicle_stop_lines.geojson` features with source-traceable properties,
+  without reading osm2streets rendered layers.
+- [ ] A Workbench user can toggle and select either marking type and see the
+  crossing node, associated road/direction, and placement evidence.
+- [ ] Native Blender/Cesium output contains both marking types using existing
+  materials, after `blender,cesium,preview --road-provider native` and without
+  publishing `package/`.
+- [ ] Tests cover a marked crossing, an unmarked crossing skip, a missing or
+  ambiguous native-road placement skip, and output-layer contract checks.
+
+## Out Of Scope
+
+- Hand-placed control-marking overrides, traffic-signal state-machine changes,
+  freehand polygon editing, processing another region, and importing
+  osm2streets-rendered crosswalk geometry.
+
+## Key Decision
+
+The first version is explicit-OSM-only. This is feasible for Nantaizi and
+keeps control markings evidence-backed; missing data remains a diagnostic for
+OSM improvement rather than a silent geometric guess.
