# WBV2-P1151-001: verify Grease Pencil modifier reader batch

- task: WBV2-P1151-001
- parent: WBV2-P1151-000
- status: done
- 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.
