- 高德 GeoJSON 参考流程: `scripts/lib/gaode-junction-reference.js` 与 `scripts/inspect-junction-reference.js` 将 GCJ-02 参考转换为 WGS84, 按 node id/最近距离关联 OSM, 支持普通路口面和 `complex-cluster` 两种匹配。 - 复合路口模板 `complex-junction-v1`: `scripts/lib/complex-junction.js` 用参考 几何校准 core 半径, 生成路口面、进口路面、斑马线、停止线、角部圆角与安全岛; 拓扑/信号/连接全部沿用 OSM/native。 - 车道中心线控制要素避让: `compileLaneCenterlines` 现接收模板已产出的斑马线/停止线, 新增 `trimLaneOutsideControls` 按到路口中心的半径定向裁剪; 标线源几何同步裁剪, 不再 越过斑马线继续画到核心区。拓扑几何不变, connector 集合前后一致。 - 复合路口人行道转角: `buildComplexJunctionGeometry` 沿已定义的路缘生成 2m 宽转角带, 复用圆角曲线, 通过 `islands` 通道并入 `sidewalk_surface`; 自交或坐标非有限时报 `complex-junction-sidewalk-corner-fallback` 并跳过。 - 新增诊断: `complex-junction-configured-radius-ignored`、 `lane-centerline-fully-inside-control`、`complex-junction-sidewalk-corner-fallback`。 - 死码清理: 移除未被调用的 `clusterApproachRing`。 - spec 更新: `.trellis/spec/pipeline/cli-and-stages.md` 复合路口小节补充控制要素 避让顺序、人行道转角契约、Validation 矩阵三行; 索引新增导航。 - 任务产物 `08-19-gaode-junction-reference`: 8 条验收标准全部实测记录, Scope Drift / Verification Log / Known Gaps 三节沉淀本次工作。 Regression: test:native-road / test:road-workbench / test:preflight / test:native-preview-traffic / test:package-contract / test:traffic-signals / test:gaode-junction-reference 全绿; road:check ok=true, errors=[]。
