+# Web Blender 全功能缺口盘点
+
+盘点基线：`tests/golden/WBV2/dynamic-inventory.json`、
+`tests/golden/WBV2/dynamic-coverage-bindings.json`、当前 WebEngine 协议/能力注册表。
+
+## 当前结论
+
+直接 WebEngine 命令已经全部进入协议和原生分发：`96/96 web-command`
+均有绑定。节点注册也已完成共享 reader 覆盖：`497/497 node`。因此
+`16/16` 工作流完成只表示产品主路径已接通，不表示 Blender 的所有用户能力
+已经迁移。
+
+当前仍未绑定的源单元：
+
+| 类型 | 总量 | 已绑定 | 未绑定 | 处理策略 |
+| --- | ---: | ---: | ---: | --- |
+| 编辑器 operator | 2018 | 31 | 1987 | 按用户能力批量迁移；窗口/屏幕/文件浏览器改用 Web 等价流程 |
+| RNA struct | 979 | 306 | 673 | 建立 Main 数据块反射/读写批次，先覆盖用户可编辑数据 |
+| node | 497 | 497 | 0 | 共享图 reader 已覆盖，后续只补具体用户入口缺口 |
+| modifier source | 97 | 95 | 2 | 将剩余 modifier 接入统一栈参数模型 |
+| operator macro | 58 | 0 | 58 | 拆解为已有原生命令组合，不复制桌面上下文 |
+| WebEngine command | 96 | 96 | 0 | 保持现有协议/Worker/Main 契约 |
+
+## Operator 缺口热点
+
+未绑定 editor operator 按源码注册文件聚合后的最大缺口：
+
+| 源码区域 | 数量 | 后续批次 |
+| --- | ---: | --- |

+
+Window manager, screen, interface, text editor and native file-browser operators
+remain explicit browser/OS boundaries. They are not claimed as missing Web
+features when a browser-native equivalent exists.
+
+## Implementation order
+
+1. User-visible authoring gaps that reuse existing Main transactions: object,
+   mesh, curve, armature, animation, sequencer, physics.
+2. Browser-native media/data workflows: tracking, masks, Grease Pencil, render,
+   asset libraries and interchange.
+3. Generic RNA reflection for the remaining data-block fields.
+4. Macro decomposition and operator catalog expansion only where a real Web
+   workflow exists; no arbitrary desktop-context emulation.
+
+Verification remains incremental and deferred to user operation. No completion
+claim is made from inventory counts alone.
