+## 目标
+
+以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 MOD_grease_pencil_util, MOD_meshcache_mdd, MOD_meshcache_pc2, MOD_meshcache_util, MOD_weightvg_util 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: existing Chromium receipts
+- Chromium test: `tools/web/reuse-wbv2-source-dependencies.mjs`
+- Selected modifier units: `modifier-source:MOD_grease_pencil_util`, `modifier-source:MOD_meshcache_mdd`, `modifier-source:MOD_meshcache_pc2`, `modifier-source:MOD_meshcache_util`, `modifier-source:MOD_weightvg_util`
+- 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-P1153-001 --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-P1153-001/module-receipt.json`
+- Aggregate production evidence: `tests/golden/WBV2-P1153-001/modifier-reader-batch-production.json`
