# Web Blender V1 当前执行计划
更新时间：2026-08-14
## 1. 交付目标
当前交付物是 `Web Blender Modeler V1`，不是 Blender 5.2 的完整浏览器移植。
V1 产品承诺、明确排除项和发布门以 `WEB_BLENDER_MODELER_V1_SCOPE.md` 为准。
浏览器基线仅为 Chromium。产品架构保持为：
```text
React 工作区和编辑器
-> versioned TypeScript protocols
-> Web Workers
-> Blender Main / Depsgraph WASM 子集
-> binary SceneIR / Three.js WebGL 或 OffscreenCanvas viewport
-> OPFS 大文件 + IndexedDB 元数据
```
本计划是当前唯一的短周期领取队列。长期 Blender 功能对标仍记录在
`BLENDER_5_2_WEB_FEATURE_PARITY.md` 和 `status/parity-ledger.json`，但不以长期全域差距
阻断已明确限定范围的 V1。
## 2. 文档与事实源
| 文件 | 唯一职责 |
| --- | --- |
| `WEB_BLENDER_MODELER_V1_SCOPE.md` | V1 产品契约、支持矩阵、非目标、发布标准 |
| `CURRENT_EXECUTION_PLAN.md` | 当前任务顺序、最小任务、依赖和退出条件 |
| `PROJECT_STATUS_AND_NEXT_WORK.md` | 已实现能力、风险、验证命令总览 |
| `BLENDER_5_2_WEB_FEATURE_PARITY.md` | Blender 5.2 全域长期差距 |
| `status/parity-ledger.json` | 功能域和 V1 slice 的机器事实 |
| `status/release-evidence.json` | 最近一次可审计发布证据快照 |
文档冲突时按上表职责解释；机器状态冲突时以校验脚本能够同时验证的 ledger 和 evidence
为准，不靠描述性文字覆盖失败结果。
## 3. 完成规则
### 3.1 最小任务规则
每个任务只产生一个主要行为变化或一个证据变化。任务状态只允许：
- `[ ]` 未开始；
- `[~]` 正在执行；
- `[x]` 已实现且验收通过；
- `[!]` 有可复现阻断，必须附命令、错误和解除条件。
不能仅凭协议存在、fixture 存在、UI 可显示或测试代码已写入，就把任务标为完成。
### 3.2 功能任务完成定义
适用项必须同时具备：
1. 正例使用生产代码路径，不在测试中复制另一套实现。
2. 非法输入、预算超限或未声明能力返回稳定结构化错误码。
3. Worker 可取消；取消后不得发布迟到结果。
4. 资源释放可观测；释放后 CPU/WASM/GPU/OPFS 临时占用回到预算内。
5. Main 或持久化状态修改必须经过 revision，验证 undo/redo、原子保存和重开。
6. 浏览器行为至少在 Chromium 生产配置验证；视口相关能力覆盖主线程和
OffscreenCanvas Worker，除非 V1 范围明确只承诺其中一个。
7. 独立验收命令退出码为 0，并产生至少一个与实现或测试绑定的 SHA-256。
8. 状态文档、ledger、evidence 和代码描述一致。
### 3.3 发布证据规则
`release-evidence.json` 中任何 `true` 字段必须：
- 由成功 evidence record 绑定；
- 记录实际命令、耗时、输出摘要和非空构件 SHA-256；
- 失败时不能保留过期成功状态；
- 不得用 mock、跳过、仅 schema 单测或只有 hash 格式校验替代真实运行。
## 4. 重新盘点后的事实基线
### 4.1 已完成工程基础
- React/Three.js 工作区、主线程 WebGL 与 OffscreenCanvas Worker 视口已存在。
- Blender 5.2 Main 子集已编译为 WASM，Worker/C ABI、结构化错误和内存统计已存在。
- `.blend` 导入、已声明编辑命令、undo/redo、保存、OPFS/IndexedDB、重启重开已形成闭环。
- 二进制 Mesh/非 Mesh SceneIR、range patch、LOD cache、GLB 和有限 USD 路径已存在。
- VDB desktop/server converter、HTTP range/OPFS、Float32 NanoVDB WebGPU、有限多 grid
材质、显式 resident LRU 和故障恢复已存在。
- 12 个 N-015 至 N-026 功能域的 Blender 全域 `parityStatus` 均为 `BLOCKED`；其 V1
required slice 的 `releaseStatus` 均为 `READY`。这两个状态轴不得再次合并。
### 4.2 2026-08-14 本轮复核结果
| 检查 | 结果 |
| --- | --- |
| `npm --prefix web run typecheck` | 通过 |
| `npm --prefix web run lint` | 通过 |
| `npm --prefix web test` | 9/9 通过 |
| `npm --prefix web run test:status-consistency` | 通过；12 parity blocked、0 release blocked |
| `npm --prefix web run test:release-evidence` | 通过；17 records、0 missing、`READY` |
### 4.3 真实发布缺口
当前 V1 release gate 已无 evidence 字段缺失，`faults.oom` 由独立 Chromium 四场景命令和
构件 hash 绑定。`geometry1M`、4K/8K texture、600 帧 simulation cache、断网、device loss、
恶意 blend、zip bomb、离线包和 V1 用户闭环仍须在 M5 全矩阵中持续回归。Blender 全域
`parityStatus=BLOCKED` 的长期差距不因 V1 gate `READY` 而关闭。
## 5. 里程碑总览
| 里程碑 | 交付物 | 状态 | 退出条件 |
| --- | --- | --- | --- |
| M0 范围与状态模型 | V1 契约、双轴 ledger、P0 用户闭环 | 已完成，持续回归 | 状态一致性与 V1 闭环通过 |
| M1 当前工作区收口 | VDB/WebGPU 与现有证据可复验 | 已完成，持续回归 | 静态门、VDB 全矩阵、V1 闭环全部通过 |
| M2 10M geometry | 大几何浏览器性能与恢复证据 | 已完成，持续回归 | `performance.geometry10M=true` |
| M3 long media | 长时间线索引、seek、取消与重启证据 | 已完成，持续回归 | `performance.longMedia=true` |
| M4 OOM | 四类确定性内存故障与恢复证据 | 已完成，持续回归 | `faults.oom=true` |
| M5 V1 RC | 可复现离线候选包、SBOM、校验和 | 未开始 | release gate `READY` |
任务严格按 M1 -> M2 -> M3 -> M4 -> M5 领取。里程碑内部允许先写纯校验任务，但不得在
前一里程碑失败时把后一里程碑标为完成。

LOD，并能取消、释放和恢复。禁止构造 10M 元素 JSON，禁止同时保留多份完整源数组。
### M2.1 契约和预算

# Web Blender Modeler V1 发布范围
更新时间：2026-08-14
## 1. 产品定义
V1 是复用 Blender 5.2 Main、文件格式和有界编辑能力的浏览器建模器，不是桌面
Blender 的窗口、渲染器、Python 和插件体系的逐项移植。发布名称固定为
`Web Blender Modeler V1`。
浏览器基线仅为 Chromium。主线程 WebGL 和 OffscreenCanvas Worker 是两个必须通过的
生产视口路径；Firefox 和 WebKit 属于发布后的兼容性工作，不进入 V1 发布门。
## 2. V1 必须闭环的用户工作流
以下能力必须同时满足 Main 权威写回、undo/redo、原子保存、Worker 重启、重新打开和
GLB 导出检查：
1. 导入和保存 `.blend`。
2. Scene、Object、Collection、Parent 和 Transform。
3. 有界 Mesh Object/Edit Mode 操作。
4. 材质槽、UV、Principled PBR 和受支持的贴图节点。
5. TRS 关键帧、Timeline、受支持的 Action/NLA 子集。
6. Armature/Pose/Constraint/Shape Key 的已声明读取和求值子集。
7. OPFS 项目、快照、资产和崩溃恢复。
8. GLB 的网格、PBR、贴图、morph、skin 和动画已声明子集。
## 3. 发布能力分类
| 分类 | 发布含义 | V1 规则 |
| --- | --- | --- |
| `LOCAL_EXACT` | 当前 fixture 与 Blender 5.2 语义一致 | 必须有 desktop/WASM golden |
| `LOCAL_BOUNDED` | 浏览器本地只支持白名单和显式预算 | 非白名单必须返回稳定错误码 |
| `SERVER` | 浏览器只提供校验、提交和结果绑定协议 | 服务端未配置时必须明确阻断 |
| `EXCLUDED` | V1 不提供且不计入本地实现承诺 | UI 不得伪造成功或静默丢数据 |
一个 family 可以整体为 `LOCAL_BOUNDED`，同时包含明确的 `SERVER` 或 `EXCLUDED`
切片。发布门检查已声明的 V1 正例和阻断行为，不把桌面 Blender 全量能力误记为完成。
## 4. 高级能力边界
| 功能域 | V1 分类 | V1 提供 | V1 不承诺 |
| --- | --- | --- | --- |
| Non-mesh/VDB | `LOCAL_BOUNDED` | Curve/Surface/Font/Metaball、PointCloud/Curves、受限 NanoVDB WebGPU | 任意 VDB 材质、无限 GPU 驻留 |
| Sculpt | `LOCAL_BOUNDED` | Mask/Face Set、四种有界 Main stroke | 完整 PBVH 和桌面全部笔刷 |
| Geometry Nodes/Simulation Zone | `LOCAL_BOUNDED` | 图、资源和确定性 cache 安全层 | 任意 lazy-function/field 本地求值 |
| Shader Nodes | `LOCAL_BOUNDED` | 已声明节点白名单和 PBR 映射 | 任意 Shader 图和通用 Web 编译器 |
| Grease Pencil/Paint | `LOCAL_BOUNDED` | 当前 Main writer、选择、预览和保存子集 | 完整 2D 编辑器、PBVH texture paint |
| Physics/Compositor/Sequencer | `LOCAL_BOUNDED` | reader、编辑、cache playback、有限 CPU executor | 完整 solver、节点全集和本地最终编码 |
| Tracking/Asset/Editors | `LOCAL_BOUNDED` | 当前 schema、Main reader/writer 和安全门 | Blender 全量 editor/operator/format |
| Cycles/复杂物理烘焙/最终视频编码 | `SERVER` | source hash、能力和结果绑定边界 | 浏览器本地等价执行 |
| Python/Text autorun/Add-ons | `EXCLUDED` | 清单读取、默认拒绝和审计 | 执行任意代码或自动安装插件 |
| 原生窗口/CUDA/Metal/HIP/OptiX | `EXCLUDED` | capability report | 浏览器平台等价 |
## 5. V1 发布门
发布候选必须具备以下自动证据：
1. P0 `import -> edit -> undo -> redo -> save -> StorageWorker/WebEngineWorker restart -> reopen -> GLB export`。
2. Chromium 主线程和 OffscreenCanvas 视口非空像素。
3. 100k、1M 和 10M geometry 的有界性能/内存结果。
4. 4K/8K texture、长时间线/媒体能力门和 simulation cache。
5. OOM 注入、device loss、network interruption、quota、malformed input 和 zip bomb 恢复。
6. 离线资源、确定性二进制/源码包、许可证、SBOM 和 source offer。
7. `docs/status/parity-ledger.json`、release evidence 和状态文档完全一致。
任何测试只能证明其命名的有界切片；不得用协议测试代替真实 Blender Main、GPU、OPFS 或
desktop golden。
