+# WBV2-P1346-001: verify MBALL_OT_delete_metaelems through existing native gate

+- task: WBV2-P1346-001
+- parent: WBV2-P1346-000
+- status: in_progress
+- gap: capability:OBJECT_DELETE_MACRO_BATCH
+- ownerFamily: OBJECT
+- targetImplementationClass: LOCAL_EXACT
+- batchId: WBV2-P1346-001:OBJECT_DELETE_MACRO_BATCH:51c6038df857be73

+
+## 目标
+
+以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 MBALL_OT_delete_metaelems 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/basic_scene.blend`
+- Chromium test: `web/tests/e2e/wbv2-object-delete-batch-production.spec.ts`
+- Selected modifier units: `modifier-source:MBALL_OT_delete_metaelems`
+- 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-P1346-001 --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-P1346-001/module-receipt.json`
+- Aggregate production evidence: `tests/golden/WBV2-P1346-001/modifier-reader-batch-production.json`
+- Manifest: `tests/golden/WBV2-P1346-001/manifest.json`
+- Status: `docs/status/WBV2-P1346-001.md`
+- Rollback: restore WBV2-P1346-000 as queue parent without rewriting prior evidence.
