# WBV2-P1160-001: verify line style modifier subtype reader batch

- task: WBV2-P1160-001
- parent: WBV2-P1160-000
- status: done
- gap: capability:LINE_STYLE_SUBTYPE_READER_BATCH
- ownerFamily: DRAWING
- targetImplementationClass: LOCAL_EXACT
- Implementation entrypoint: `node tools/web/run-wbv2-module-task.mjs --task WBV2-P1160-001 --write`

## 目标

使用一个共享 Blender Main/WASM/Worker/Chromium 链验证 0 个 modifier source 与 39 个 RNA unit，形成一个聚合 receipt。

## 输入与范围

- Blender source family: `blender-5.2.0/source/blender`
- Fixtures: `tests/files/web/line_style_subtype_batch_scene.blend`
- Chromium test: `web/tests/e2e/wbv2-line-style-reader-production.spec.ts`
- Unit selection: `39 units`（完整列表只在 module plan/manifest）

## 验收

- one shared function chain covers every selected unit exactly once
- malformed input, unsupported data and hash drift fail closed without Main mutation
- save/reopen, deterministic second read and Chromium evidence are exact
- `node tools/web/check-task-context.mjs --task WBV2-P1160-001 --write`

## 失败边界

- partial batch success never advances or claims omitted units
- existing source/receipt hashes are reused; historical inventory remains read-only

## 交付与回滚

- Aggregate receipt: `tests/golden/WBV2-P1160-001/module-receipt.json`
- Production evidence: `tests/golden/WBV2-P1160-001/modifier-reader-batch-production.json`
- Manifest: `tests/golden/WBV2-P1160-001/manifest.json`
- Rollback: restore WBV2-P1160-000 as queue parent.
