# W-028 Status

status: done
task: 原生/WASM 双端回归

## Evidence

- Native runner: `web/engine/web_engine_native_smoke.cpp`
- Dual runner: `tools/web/check-dual-engine.sh`
- Golden: `tests/golden/W-028/dual-engine.json`

The same C ABI returns matching create, invalid-empty-open, and destroy
results in native C++ and Emscripten builds. The WASM runner additionally
opens local `.blend` fixtures, checks SceneIR, verifies an authoritative
Main save/reopen, verifies ordinary decimate Main write/save/reopen, and verifies that the
skin/shape-key decimate boundary blocks save with `BLEND_WRITE_REQUIRES_MAIN_AUTHORITY`.

## Verification
