# WBV2-P31-000: authorize_resource_scene_workbench

- task: WBV2-P31-000
- parent: WBV2-P30-004
- status: done
- gap: workflow:authorize_resource_scene_workbench
- ownerFamily: PROGRAM
- targetImplementationClass: SOURCE_BACKED

## 目标

Authorize the next source-backed resource and scene-data implementation wave.

## 输入与范围

- Focused protocol: `web/protocol/web-engine.ts`
- Implementation entrypoint: `node tools/web/generate-wbv2-resource-scene-root.mjs`

## 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-P31-000 --write`

## 失败边界

- malformed and unsupported resource payloads fail closed with a typed diagnostic
- implementation evidence never changes the historical inventory or provenance epoch

## 交付与回滚

- Reports: `tests/golden/WBV2-P31-000/`
- Status: `docs/status/WBV2-P31-000.md`
- Manifest: `tests/golden/WBV2-P31-000/manifest.json`
- Rollback: restore WBV2-P30-004 as queue parent and leave the task in_progress.
