# WBV2-P1129-001: verify scene settings module

- task: WBV2-P1129-001
- parent: WBV2-P1129-000
- status: in_progress
- gap: workflow:core_scene_graph_settings
- ownerFamily: CORE_SCENE
- targetImplementationClass: LOCAL_EXACT
- moduleId: CORE_SCENE_GRAPH_SETTINGS
- Implementation entrypoint: `node tools/web/run-wbv2-module-task.mjs --task WBV2-P1129-001 --write`

## 目标

Verify the existing Blender Main compositor, performance and sampling setting transactions as one source-backed module. This adds aggregate production evidence without duplicating the P1128 movie implementation or older scene-setting receipts.

## 输入与范围

- Source paths:
- `blender-5.2.0/source/blender/web_engine/web_engine_main_state.cpp`
- `blender-5.2.0/source/blender/web_engine/web_engine_main_state.h`
- `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`
- `web/protocol/web-engine.ts`
- `web/app/src/workers/web-engine.worker.ts`
- `web/app/src/app/App.tsx`
- `web/tests/e2e/wbv2-scene-settings-production.spec.ts`
- Reused receipts:
- `tests/golden/WBV2-P65-002/manifest.json` + `tests/golden/WBV2-P65-002/implementation-report.json`
- `tests/golden/WBV2-P66-002/manifest.json` + `tests/golden/WBV2-P66-002/implementation-report.json`
- `tests/golden/WBV2-P67-002/manifest.json` + `tests/golden/WBV2-P67-002/implementation-report.json`
- Production test: `web/tests/e2e/wbv2-scene-settings-production.spec.ts`

## 验收

- Positive: compositor device/precision mutation, performance thread/persistence mutation, sampling filter/dither mutation
- Negative: invalid sampling range, unknown scene target, malformed property set
- Recovery: undo, redo, save/reopen, deterministic scene settings snapshot
- Commands:
- `npm --prefix web run typecheck`
- `npm --prefix web run build`
- `WEB_TEST_PORT=5344 npm --prefix web run test:e2e -- --workers=1 tests/e2e/wbv2-scene-settings-production.spec.ts`
- Missing source, hash drift, malformed input or browser failure remains in_progress and does not advance the queue.

## 交付与回滚

- Receipt: `tests/golden/WBV2-P1129-001/module-receipt.json`
- Manifest: `tests/golden/WBV2-P1129-001/manifest.json`
- Status: `docs/status/WBV2-P1129-001.md`
- Rollback: restore WBV2-P1129-000 as the queue parent and leave this module in_progress.
