- task: WBV2-P10-002
- parent: WBV2-P10-001
- status: in_progress
- gap: workflow:bind_native_and_wasm_engine_receipts
- ownerFamily: ENGINE
- targetImplementationClass: LOCAL_EXACT

## 目标

Bind the proven Mesh, Modifier, and Asset Catalog mutations to the compiled Blender native binary and the checked-in web_engine.wasm runtime, with Chromium as the browser gate.

## 输入与范围

- Native binary: `build_blender_native/bin/blender`
- WASM binary: `web/app/src/vendor/blender/web_engine.wasm`
- WASM loader: `web/app/src/vendor/blender/web_engine.js`
- Native Web Engine API: `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`
- Existing P9 capability receipts: `tests/golden/WBV2-P9-004/feature-parity-gate-report.json`

## 生产入口

- WebEngine client: `web/app/src/engine-client/WebEngineClient.ts`
- WebEngine worker: `web/app/src/workers/web-engine.worker.ts`
- Production receipt test: `web/tests/e2e/wbv2-native-engine-production.spec.ts`

## 验收

- `build_blender_native/bin/blender --version`
- `node tools/web/check-wbv2-native-engine.mjs --write`
- `npm --prefix web run test:e2e -- --workers=1 tests/e2e/wbv2-native-engine-production.spec.ts`
- `node tools/web/generate-wbv2-native-engine-receipt.mjs --write`
- `node tools/web/check-task-context.mjs --task WBV2-P10-002 --write`

Missing binary, source hash drift, fake bridge execution, unsupported browser, non-exact save/reopen, or failure mutation must keep in_progress and must not advance nextTask.
