+## E15: 编辑器架构重构 — 三层分离
+
+目标：为应对状态增多和功能复杂化，确保扩展性和可维护性。编辑器重构为三层分离架构，与引擎分层一致。
+
+**当前问题：** `App.vue` 310 行 god 组件 / `useGraphEditor.ts` 混合 JSON + Vue refs / 无 Pinia store
+
+**目标架构：**
+
+```
+editor/
+├── services/                GraphService.ts + AssetResolver.ts    # 纯函数数据层
+├── stores/                  editorStore.ts                       # Pinia 全局状态 + undo/redo
+├── composables/             useGraphEditor.ts                    # 编排层（→60行）

+└── App.vue                  # 精简布局组合（→30行）
+```
+
+**实施步骤：**
+1. 创建 `editorStore.ts`（Pinia）
+2. 创建 `GraphService.ts`（纯函数剥离）
+3. 精简 `App.vue` + `useGraphEditor`
+4. 新增 `SceneList.vue` + `StatusBar.vue`
