- task: `WBV2-P1115-000`
- parent: `WBV2-P1114-000`
- status: `in_progress`
- gap: `workflow:module_curve_surface_editing`
- ownerFamily: `GEOMETRY`
- targetImplementationClass: `LOCAL_EXACT`

## 目标

按功能模块验证 Curve topology/handle、Surface topology、Font 属性和 non-mesh save/reopen roundtrip。

## 输入与范围

- Blender Main/API/reader: `blender-5.2.0/source/blender/web_engine/web_engine_main_state.cpp`, `blender-5.2.0/source/blender/web_engine/web_engine_main_state.h`, `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`, `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
- Protocol: `web/protocol/web-engine.ts`, `web/protocol/nonmesh-geometry-commands.ts`, `web/protocol/curve-topology-editor.ts`, `web/protocol/non-mesh.ts`
- Runtime: `web/app/src/engine-client/WebEngineClient.ts`, `web/app/src/workers/web-engine.worker.ts`, `web/app/src/app/App.tsx`
- Existing receipt: `tests/golden/WBV2-P12-004/manifest.json`

## 验收

```bash
npm --prefix web run test:curve-topology-operator
npm --prefix web run test:nonmesh-roundtrip
npm --prefix web run test:nonmesh-desktop-golden
npm --prefix web run typecheck
```

必须记录 Curve/Surface/Font 正例、非法 selection/domain/属性负例、undo/redo、save/reopen、多 spline 确定性和 Chromium/desktop golden。GLB temporary bundle 缺依赖不在本模块绕过。

## 交付与回滚

- Receipt: `tests/golden/WBV2-P1115-000/module-receipt.json`
- Manifest: `tests/golden/WBV2-P1115-000/manifest.json`
- Status: `docs/status/WBV2-P1115-000.md`
