- parent: WBV2-P17-000
- status: in_progress
- gap: capability:OBJECT_OPERATIONS.DUPLICATE
- ownerFamily: PARITY
- targetImplementationClass: LOCAL_BOUNDED

## 目标

Select the duplicateObject behavior and one exact legacy operator binding.

## 输入与范围

- Focused source: `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`
- Existing client: `web/app/src/engine-client/WebEngineClient.ts`
- Inventory: `tests/golden/WBV2-P0-002/parity-map.json`
- Production entrypoint: `node tools/web/generate-wbv2-object-selection.mjs --write`

## 验收

- source command is hash-bound
- existing Scene/Object visibility and transform evidence is not rerun
- candidate remains one behavior
- malformed, hash-drift, unsupported, or false-completion input keeps in_progress
- `node tools/web/check-task-context.mjs --task WBV2-P17-001 --write`

## 交付与回滚

- Status: `docs/status/WBV2-P17-001.md`
- Manifest: `tests/golden/WBV2-P17-001/manifest.json`
