+**设计决策（对标 Detroit / Dark Pictures）：**
+
+| 决策 | 做法 |
+|------|------|
+| **结局存储** | 共用 `visitedSceneIds`，不独立建表。`endings` 数组声明哪些场景是结局，画廊查 `visitedSceneIds.has(sceneId)` |
+| **路径追踪** | **节点级** `visitedSceneIds: Set<string>` — `goToScene` 中 `visited.add(scene.id)` |

 **实现清单：**
 
-- [ ] `engine/types.ts` — `GameData.endings`、`EndingDef`
-- [ ] `engine/systems/SaveSystem.ts` — DB v5 新增 `endings` + `visited` 表
-- [ ] `engine/core/Engine.ts` — `goToScene` 标记结局 + 记录 visited scene
-- [ ] `src/components/EndingGallery.vue` — 结局缩略图网格 + 锁定/解锁
-- [ ] `src/components/ChapterRecap.vue` — Vue Flow 只读分支图 + 路径高亮
-- [ ] `src/stores/gameStore.ts` — 结局/visited 状态
-- [ ] `src/App.vue` — 主菜单"画廊"入口 + 游戏结束整合回顾
-- [ ] `public/scenes/demo.json` — endings 定义 + 结局缩略图
