## 目标

以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 GeometryNodeSetInstanceTransform, GeometryNodeSetMaterial, GeometryNodeSetMaterialIndex, GeometryNodeSetMeshNormal, GeometryNodeSetNURBSOrder 的真实 modifier/RNA 元数据。

## 输入与范围

- Blender modifier sources: `blender-5.2.0/source/blender/modifiers/intern/`
- RNA source: `blender-5.2.0/source/blender/makesrna/intern/rna_modifier.cc`
- Native reader: `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
- Fixtures: `tests/files/web/generated/wbv2-geometry-95ccfa5892bb7a33.blend`
- Chromium test: `web/tests/e2e/geometry-node-main-reader.spec.ts`
- Selected modifier units: `modifier-source:GeometryNodeSetInstanceTransform`, `modifier-source:GeometryNodeSetMaterial`, `modifier-source:GeometryNodeSetMaterialIndex`, `modifier-source:GeometryNodeSetMeshNormal`, `modifier-source:GeometryNodeSetNURBSOrder`
- Selected RNA units: none (source-only dependency batch)

## 验收

- one shared Main/WASM/Worker/Chromium chain observes every selected type
- malformed input is rejected without Main mutation
- save/reopen and deterministic second read are exact
- only Chromium is used; JS simulation and per-API duplicate workers are forbidden
- each selected source unit receives an explicit hash-bound coverage binding
- `node tools/web/check-task-context.mjs --task WBV2-P1237-001 --write`

## 失败边界

- any missing source, unsupported type, hash drift, malformed data or non-exact recovery keeps the batch `in_progress`/`blocked`
- partial batch success never claims the omitted family; historical inventory remains read-only

## 交付与回滚

- Receipt: `tests/golden/WBV2-P1237-001/module-receipt.json`
- Aggregate production evidence: `tests/golden/WBV2-P1237-001/modifier-reader-batch-production.json`
- Manifest: `tests/golden/WBV2-P1237-001/manifest.json`
- Status: `docs/status/WBV2-P1237-001.md`
- Rollback: restore WBV2-P1237-000 as queue parent without rewriting prior evidence.
