+# WBV2-P1151-001: verify Grease Pencil modifier reader batch
+
+- task: WBV2-P1151-001
+- parent: WBV2-P1151-000
+- status: in_progress
+- gap: capability:GREASE_PENCIL_MODIFIER_READER_BATCH
+- ownerFamily: DRAWING
+- targetImplementationClass: LOCAL_EXACT
+- Implementation entrypoint: `node tools/web/run-wbv2-module-task.mjs --task WBV2-P1151-001 --write`
+
+## 目标
+
+使用一个共享 Blender Main/WASM/Worker/Chromium 链验证 25 个 Grease Pencil modifier source 和 23 个 RNA unit，形成一个聚合 receipt。
+
+## 输入与范围
+
+- Blender source family: `blender-5.2.0/source/blender`
+- Fixture: `tests/files/web/modifier_grease_pencil_scene.blend`
+- Chromium test: `web/tests/e2e/wbv2-modifier-reader-batch-two-production.spec.ts`
+- Complete unit list: `tests/golden/WBV2-P1151-000/module-execution-plan.json`
+
+## 验收
+
+- one shared function chain covers every selected modifier type exactly once
+- malformed input is rejected without Main mutation
+- save/reopen and deterministic second read are exact in Chromium
+- existing source/receipt evidence is reused before any new run
+- every selected unit gets an explicit hash-bound coverage binding
+- `node tools/web/check-task-context.mjs --task WBV2-P1151-001 --write`
+
+## 失败边界
+
+- partial or unsupported Grease Pencil data keeps the batch `in_progress`/`blocked`
+- no full-family parity or historical inventory mutation is claimed
+
+## 交付与回滚
+
+- Aggregate receipt: `tests/golden/WBV2-P1151-001/module-receipt.json`
+- Production evidence: `tests/golden/WBV2-P1151-001/modifier-reader-batch-production.json`
+- Manifest: `tests/golden/WBV2-P1151-001/manifest.json`
+- Rollback: restore WBV2-P1151-000 as queue parent without rewriting prior evidence.
