- parent: WBV2-P1100-002

## 目标

Complete one coherent Blender function module through shared Main primitives and an aggregate operator case matrix.

## 输入与范围

- Source paths:
- `blender-5.2.0/source/blender/web_engine/web_engine_main_state.cpp`
- `blender-5.2.0/source/blender/web_engine/web_engine_main_state.h`
- `blender-5.2.0/source/blender/web_engine/web_engine_api.cpp`
- `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
- `web/protocol/web-engine.ts`
- `web/app/src/workers/web-engine.worker.ts`
- Reused receipts:
- `tests/golden/WBV2-P12-003/manifest.json`
- `tests/golden/WBV2-P12-003/material-animation-receipt-report.json`
- Implementation and verification entrypoint: `node tools/web/run-wbv2-module-task.mjs --task WBV2-P1100-003 --write`

```
node tools/web/run-wbv2-module-task.mjs --task WBV2-P1100-003 --write
```

## 验收

Positive cases: principled material, image node, keyframe, FCurve
Negative boundaries: unsupported graph, stale revision
Recovery: undo, redo, save/reopen
Commands:
- `npm --prefix web run typecheck`
- `npm --prefix web run test:e2e -- --workers=1 tests/e2e/wbv2-material-animation-production.spec.ts`

Malformed or unsupported input must fail closed. A module advances only when source hashes, positive Main mutation, negative no-mutation, undo/redo, save/reopen, Chromium and aggregate manifest checks pass. A representative case never claims full-family parity.

## 交付与回滚

- Reports: `tests/golden/WBV2-P1100-003/`
- Manifest: `tests/golden/WBV2-P1100-003/manifest.json`
- Status: `docs/status/WBV2-P1100-003.md`
- Rollback: restore WBV2-P1100-002 as queue parent and leave this module in_progress.
