+# WBV2-P1156-000: authorize module batch

+- task: WBV2-P1156-000
+- parent: WBV2-P1155-001
+- status: done
+- gap: capability:MODIFIER_VOLUME_DISPLACE_BATCH
+- ownerFamily: MODIFIER
+- targetImplementationClass: QUEUE_ONLY
+- Implementation entrypoint: `python3 my-tools/authorize_next_wbv2_task.py --write`
+
+## 目标
+
+授权一个共享 Blender Main/WASM/Chromium 功能批次：MODIFIER_VOLUME_DISPLACE_BATCH，共 2 个源码/RNA 单元。
+
+## 输入与范围
+
+- Blender source: `blender-5.2.0/source/blender`
+- Fixtures/test: `tests/files/web/generated/M16-GAP-00106-modifier-VOLUME_DISPLACE.blend`, `web/tests/e2e/wbv2-modifier-reader-multi-fixture-production.spec.ts`
+
+## 验收
+
+- prior evidence and dynamic inventory remain hash-bound and immutable
+- one shared function chain validates the complete selected batch
+- missing source, unsupported data, hash drift or false completion remains blocked
+- `node tools/web/check-task-context.mjs --task WBV2-P1156-000 --write`
+
+## 交付与回滚
+
+- Manifest: `tests/golden/WBV2-P1156-000/manifest.json`
+- Status: `docs/status/WBV2-P1156-000.md`
+- Rollback: restore WBV2-P1155-001 as queue parent.
