# WBV2-P32-001: implement_scene_context_workbench

- task: WBV2-P32-001
- parent: WBV2-P32-000
- status: in_progress
- gap: workflow:implement_scene_context_workbench
- ownerFamily: WORKFLOW
- targetImplementationClass: SOURCE_BACKED

## 目标

Expose real SceneIR collections, libraries, armatures and workflow status in the Properties workbench.

## 输入与范围

- Focused protocol: `web/protocol/scene-ir.ts`
- Implementation entrypoint: `node tools/web/generate-wbv2-scene-context-slice.mjs --task WBV2-P32-001 --write`

## 验收

- real source or WebEngine Main path is wired
- worker/client/frontend route uses typed protocol without a duplicate shim
- malformed, unsupported, hash-drift or false-completion input fails closed
- implementation smoke is reproducible; Chromium receipts, undo/redo, save/reopen and deterministic verification remain deferred
- `node tools/web/check-task-context.mjs --task WBV2-P32-001 --write`

## 失败边界

- unavailable or blocked status data remains visibly blocked and cannot be treated as ready
- implementation evidence never changes historical inventory or provenance

## 交付与回滚

- Reports: `tests/golden/WBV2-P32-001/`
- Status: `docs/status/WBV2-P32-001.md`
- Manifest: `tests/golden/WBV2-P32-001/manifest.json`
- Rollback: restore WBV2-P32-000 as queue parent and leave the task in_progress.
