# WBV2-P1130-001: verify editor View2D module

- task: WBV2-P1130-001
- parent: WBV2-P1130-000
- status: in_progress
- gap: workflow:ui_editor_view2d_state
- ownerFamily: EDITOR
- targetImplementationClass: LOCAL_EXACT
- moduleId: UI_EDITOR_VIEW2D_STATE
- Implementation entrypoint: `node tools/web/run-wbv2-module-task.mjs --task WBV2-P1130-001 --write`

## 目标

Preserve the Blender Graph/Dope Sheet View2D `cur` and pixel `mask` state through a dedicated protocol adapter. The existing P1102 editor workflow parser remains untouched so its source hash and receipt stay reusable.

## 输入与范围

- Source paths:
- `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
- `web/protocol/editor-view2d.ts`
- `web/app/src/workers/editor-view2d-test.worker.ts`
- `web/app/src/app/App.tsx`
- `web/tests/e2e/ui-editor-view2d-production.spec.ts`
- Production test: `web/tests/e2e/ui-editor-view2d-production.spec.ts`

## 验收

- Positive: Graph main-region View2D cur retention, Graph main-region pixel mask retention, reader/protocol exact state
- Negative: inverted View2D bounds, malformed mask range, missing View2D payload
- Recovery: immutable base editor workflow, worker termination, deterministic repeated parse, save/reopen reader compatibility
- Commands:
- `npm --prefix web run typecheck`
- `npm --prefix web run build`
- `WEB_TEST_PORT=5346 npm --prefix web run test:e2e -- --workers=1 tests/e2e/ui-editor-view2d-production.spec.ts`
- malformed input, missing source, hash drift or Chromium failure remains in_progress and does not advance the queue.

## 交付与回滚

- Receipt: `tests/golden/WBV2-P1130-001/module-receipt.json`
- Manifest: `tests/golden/WBV2-P1130-001/manifest.json`
- Status: `docs/status/WBV2-P1130-001.md`
- Rollback: restore WBV2-P1130-000 as the queue parent and leave this module in_progress.
