+### P23 玩家树可视化 — 缩进树取代平铺列表 ✅ 已完成 2026-06-10
+
+目标：将 StoryGallery 的章节回顾从平铺场景列表升级为缩进树形结构。创作图的汇聚节点在树上复制展示，
+玩家看到的是严格树——每条选择路径看起来都是独立的故事线（对标 Detroit）。
+
+**核心改动：StoryGallery 的 `sceneListForChapter()` 替换为 `buildPlayerTree()`**
+——BFS 遍历图 → 保持树形父子关系 → 同节点不同路径各自复制。
+
+**数据结构：**
+
+```typescript
+interface PlayerTreeNode {
+  sceneId: string
+  label: string
+  visited: boolean
+  locked: boolean
+  lockHint?: string
+  children: PlayerTreeNode[]
 }
 ```
 
+**渲染效果对比：**
+
+```
+之前（平铺列表）：              之后（缩进树）：
+✅ intro                       ✅ intro
+✅ left_door                    ├ ✅ left_door
+⬜ trust_ending 🔒 trust>=80    │   ├ ⬜ trust_ending 🔒 trust>=80
+⬜ alone_ending                 │   └ ⬜ alone_ending
+                                 ├ ✅ right_door
+                                 │   ├ ✅ qte_success
+                                 │   │   └ ✅ continue_ending
+                                 │   └ ⬜ qte_fail
+                                 └ ✅ stay
+                                     └ ⬜ alone_ending   ← 汇聚节点，两条路径各出现一次
+```
+
+**实现改动：**
+
+| 文件 | 改动 |
+|------|------|
+| `engine/types.ts` | 新增 `PlayerTreeNode` 接口 |
+| `src/components/StoryGallery.vue` | `sceneListForChapter()` → `buildPlayerTree()`（递归渲染缩进树）+ 纯 CSS 树连线（`border-left` + `::before` 横线） |
+
+**实现清单：**
+
+- [x] `engine/types.ts` — `PlayerTreeNode { sceneId, label, visited, locked, lockHint?, children[] }`
+- [x] `src/components/TreeNode.vue` — **新建** — 递归树节点组件，`depth` 参数控制缩进 + `border-left` 竖线
+- [x] `src/components/StoryGallery.vue` — `sceneListForChapter()` → `buildPlayerTree(sceneId, depth, pathSet)` + `buildTreeForChapter()`；Template 用 `<TreeNode>` 渲染
+  - 回环检测：`pathSet: Set<string>` 记录当前路径场景 ID，精确剪枝
+  - 深度兜底：`depth > 10` 截断
+  - 汇聚节点：同一 sceneId 在不同父节点下各建一个独立的 PlayerTreeNode
+- [x] 验证：TypeScript + Vite build 通过
+
 ## 关键架构决策记录
 
 1. **引擎与 UI 分离**: `engine/` 下纯 TS 类，不 import Vue。UI 层通过 composables 桥接。

-P1 完成。TypeScript 零错误，构建通过。

-### P1 新增/修改内容
-
-| 文件 | 变更 |
-|------|------|
-| `engine/core/VideoManager.ts` | A/B 双缓冲：`playInitial()` / `switchTo()` + 300ms CSS 交叉淡化 + 候选视频预加载 |
-| `engine/core/SceneManager.ts` | 新增 `getCandidateUrls()` / `getCandidateTargetIds()` 为预加载提供目标 |
-| `engine/core/Engine.ts` | 集成 ChoiceSystem；新增 `resumeScene()` 公共方法支持存档恢复；条件过滤选项 |
-| `engine/systems/ChoiceSystem.ts` | 新增：限时选择倒计时，超时自动选第一项，通过 `choiceTimer` / `choiceTimeout` 事件通知 UI |
-| `engine/systems/SaveSystem.ts` | 新增：Dexie.js IndexedDB，5 个槽位，save/load/list/delete |
-| `engine/types.ts` | 新增 `choiceTimer` 事件 |
-| `src/components/GamePlayer.vue` | 双 `<video>` 元素，`position:absolute` 叠放，`opacity` 驱动交叉淡化 |
-| `src/components/ChoicePanel.vue` | 新增倒计时进度条 + 秒数文字，最后 3 秒变红 |
-| `src/components/SaveLoadMenu.vue` | 新增：5 槽位存档/读档面板 |
-| `src/composables/useGameEngine.ts` | 双 video 引用、saveGame/loadGameFromSlot/refreshSaves |
-| `src/stores/gameStore.ts` | 新增 timerTotal/timerRemaining/saves 状态 |
-| `src/App.vue` | 右上角"菜单"按钮，整合 SaveLoadMenu |
-| `public/scenes/demo.json` | 新增 `secret_ending` 示范条件分支（trust >= 80 才显示选项） |
-
-### 实测流程
-
-1. 点"开始游戏" → 播 intro 视频
-2. 视频结束 → 弹出 3 个选项（支持 timeLimit 倒计时）
-3. 选"左边发光的门" → 交叉淡化切换到 left_door 视频
-4. 选"与陌生人握手" → 进 trust_ending，信任 >= 80 时**额外显示**隐藏选项"开启信任的旅程"
-5. 点右上角"菜单" → 5 槽位存档/读档（存到 IndexedDB，刷新页面不丢失）

-
-_Thinking:_
-
-P2 includes:
-- QTE System (Quick Time Events) — trigger at specific times during video playback
-- Subtitle system — WebVTT parsing and rendering
-- Multi-save slots with thumbnails (canvas screenshot of current video frame)
-- Full event bus (already done from P1)
-- Verification
-
-Let me plan the implementation:
-
-1. **QTESystem** (`engine/systems/QTESystem.ts`) — Already partially defined in types, but need the full implementation:
-   - Monitor video time via timeupdate
-   - At triggerTime, show QTE prompt
-   - Listen for keyboard input
-   - Check if correct key pressed within timeLimit
-   - Route to successScene or failScene
-   - Emit events for UI
-
-2. **QTEOverlay.vue** — Visual QTE overlay with key prompt and countdown ring
-
-3. **Subtitles.vue** — Parse WebVTT and render subtitles synchronized with video time
-
-4. **Engine integration** — Wire QTE into Engine.goToScene, check for QTE definition on each scene
-
-5. **Multi-save thumbnails** — Capture current video frame to canvas and store as data URL
-
-6. **Update demo.json** — Add QTE example scene and subtitle tracks
-
-Let me read the current state of files I need to modify.

-## Assistant (Build · DeepSeek V4 Pro · 16.1s)
-
-_Thinking:_
-
-I see the App.vue has been modified from what I wrote - it has `hasAutoSave` and `resumeAutoSave` etc. The codebase has evolved. Let me work with what's there.
-
-Now let me plan P2 implementation:
-
-1. **QTESystem** - New engine system
-   - Attached to VideoManager's timeUpdate event
-   - Monitors current time against scene's QTE definition
-   - When triggerTime is reached, emits qteTrigger event
-   - Starts keyboard listener
-   - Within timeLimit, checks if pressed key matches
-   - On success -> go to successScene, apply success effects
-   - On fail/timeout -> go to failScene, apply fail effects
-   - After QTE resolves, resume normal video play flow
-
-2. **QTEOverlay.vue** - Visual component
-   - Shows when qteTrigger event fires
-   - Displays prompt text, required key, and countdown progress ring
-   - Animations for success/fail
-
-3. **Subtitles.vue** - Subtitle component
-   - Parses WebVTT from scene.subtitleUrl
-   - Renders current cue based on video time
-
-4. **Save thumbnails** - Canvas screenshot of active video
-
-5. **Engine changes** - Wire QTE in goToScene
-
-Let me implement these now. I'll write all files.
-
-Key design decisions:
-- QTE is managed by the Engine, which already has access to VideoManager's time updates
-- Need to add QTE-related events: `qteTrigger`, `qteSuccess`, `qteFail`
-- The QTE state needs to go into gameStore
-- SubtitleUrl is already in the SceneNode type - just need to implement the parsing and rendering
-
-Let me start implementing.
-
-Now implementing P2. Let me create all files in parallel batches — engine systems first, then Vue components.

-_Thinking:_
-
-Now I need to integrate QTESystem into the Engine. The QTE should be checked on timeupdate - when the video time crosses triggerTime, QTE fires. Let me update Engine.
-
-The flow:
-1. In goToScene(), check if scene has a QTE definition
-2. Register a timeupdate handler that checks if currentTime >= qte.triggerTime
-3. When triggered, call qteSystem.trigger()
-4. On QTE success, go to qte.successScene with success effects
-5. On QTE fail, go to qte.failScene with fail effects
-6. Don't fire the normal onVideoEnd for this scene (since QTE handles the transition)
-
-Let me update Engine:

-P2 is complete. Let me provide a summary of what was done.
-
-P2 完成。TypeScript 零错误，构建通过。
-
-### P2 新增/修改内容
-
-| 文件 | 变更 |
-|------|------|
-| `engine/systems/QTESystem.ts` | 新增：键盘监听（多键匹配）、50ms 轮询计时器、超时/成功/取消 |
-| `engine/core/Engine.ts` | 集成 QTE：`goToScene` 注册 timeupdate → `checkQTE` → `qteSystem.trigger` → 成功/失败跳转 |
-| `engine/types.ts` | 新增 `qteTimer`、`qteResult` 事件 |
-| `engine/core/VideoManager.ts` | 新增 `getActiveVideoElement()` 供存档截图 |
-| `engine/systems/SaveSystem.ts` | DB v2 升级，支持 `thumbnail` 字段（canvas 截图 base64） |
-| `src/components/QTEOverlay.vue` | SVG 倒计时环 + 按键显示 + 成功(绿)/失败(红)反馈 |
-| `src/components/Subtitles.vue` | WebVTT 解析器（时间码 → 秒转换），同步当前字幕 |
-| `src/components/SaveLoadMenu.vue` | 64x36 存档缩略图预览 + 自动保存提示 |
-| `src/stores/gameStore.ts` | 新增 QTE 状态组（qteActive, qteDef, qteResult, videoTime） |
-| `src/composables/useGameEngine.ts` | 桥接 qteTrigger/qteTimer/qteResult 事件 + 缩略图截图逻辑 |
-| `src/App.vue` | 整合 QTEOverlay、Subtitles |
-| `public/scenes/demo.json` | right_door 场景新增 QTE 配置；intro/left_door/stay 新增字幕 |
-| `public/subtitles/*.vtt` | 3 个字幕文件（intro/left_door/stay） |
-| `public/videos/qte_{success,fail}.mp4` | 2 个 QTE 结果视频 |
-
-### 实测流程
-
-1. 选"右边的门" → 播 right_door 视频
-2. 1 秒后 QTE 触发 → 屏幕中央出现倒计时环 + "躲避飞来的石块！" + ←/→/A/D 提示
-3. 3 秒内按方向键 → 成功跳到 `qte_success`（绿环反馈）/ 超时跳到 `qte_fail`（红环反馈）
-4. 字幕在对应场景底部同步显示
-5. 进菜单存档时自动截取当前视频帧作为缩略图

-1. Install @vue-flow/core, @vue-flow/background, @vue-flow/controls
-2. Create editor entry point (editor/index.html, editor/main.ts, editor/App.vue)
-3. Create Vue Flow scene graph component

-_Thinking:_
-
-Now let me create the editor composable, then the components. Let me think about the graph data model:
-
-Scene graph:
-- Each node = a scene. Node data = { id, videoUrl, subtitleUrl, choices, qte, nextScene, onEnter }
-- Each edge = represents a choice target or nextScene target
-- Edge data = { choiceIndex?, condition?, effect? } - carries the choice definition
-
-For the graph editor:
-1. Nodes can be added/deleted
-2. Edges can be added between nodes (represents a choice or nextScene)
-3. When an edge is edited, we update the source node's choices
-4. When a node is clicked, the right panel shows its properties
-5. Import/Export JSON
-
-Let me design the useGraphEditor composable:
-
-```typescript
-function jsonToGraph(json: GameData): { nodes: Node[], edges: Edge[] } { ... }
-function graphToJson(nodes: Node[], edges: Edge[]): GameData { ... }
-```
-
-Node/Vue Flow nodes:
-- Each scene becomes a node
-- Each choice becomes an edge from source scene to target scene
-- nextScene becomes a special edge

-Wait, there's a problem with Vue Flow usage. The `v-model:nodes` and `v-model:edges` expect reactive refs, not computed. And the `useVueFlow` needs to be used inside a VueFlow context. Let me rethink the approach.
-
-In Vue Flow v1.x, I should be using `<VueFlow :nodes="nodes" :edges="edges">` (not v-model), and `useVueFlow` returns reactive `nodes` and `edges` refs that I can populate.

-## User
-
-交互式电影游戏中有一种功能，画面展示一张图片，点击图片的不同位置，触发不同的分支逻辑，你知道吗?
-
----
-
-## Assistant (Plan · DeepSeek V4 Pro · 20.2s)
-
-_Thinking:_
-
-The user is asking about a feature in interactive movie games where you display an image and clicking on different parts of the image triggers different story branches. This is commonly known as "image hotspot" or "clickable image" mechanics - similar to point-and-click adventures or visual novels with interactive backgrounds.
-
-Examples:
-- "Her Story" - clicking on video clips
-- Point-and-click adventure games where you click on objects in a scene
-- Hidden object games
-- Visual novels where you can click on characters or objects in a scene to investigate
-
-The user is asking if I know about this feature, and presumably wants to discuss adding it to their engine.
-
-Let me think about how this could be integrated:
-
-1. **A new scene type**: "image" or "hotspot" scene that replaces/supplements video playback
-2. **Hotspot regions**: Define clickable areas on the image with associated choices/branches
-3. **Data format**: Each hotspot has coordinates (x, y, width, height or polygon), associated text/label, and target scene
-4. **Rendering**: Overlay invisible clickable regions on top of the displayed image
-
-Let me describe this clearly and confirm the user's intent. Since we're in plan mode (read-only), I should just discuss and plan, not implement.
-
-知道。这叫**图片热点交互**——用一张静态图替代视频，在图上定义可点击区域（热点），点击不同位置触发不同分支。
-
-常见于：
-- 调查/解谜场景（点击房间里的物品获取线索）
-- 地图选择（点击地图上的不同地点前往不同区域）
-- 线索推理（点击人物/物体的关键部位）
-
-在 JSON 场景数据中，大概是这样：
-
-```json
-{
-  "id": "crime_scene",
-  "type": "image",
-  "imageUrl": "/images/crime_scene.jpg",
-  "hotspots": [
-    {
-      "id": "desk",
-      "x": 100, "y": 200, "width": 150, "height": 80,
-      "label": "查看书桌",
-      "targetScene": "desk_detail",
-      "conditions": [{ "variable": "investigation", "op": ">=", "value": 1 }]
-    },
-    {
-      "id": "window",
-      "x": 600, "y": 50, "width": 120, "height": 200,
-      "label": "查看窗户",
-      "targetScene": "window_detail"
-    },
-    {
-      "id": "body",
-      "x": 350, "y": 300, "width": 80, "height": 150,
-      "label": "检查尸体",
-      "targetScene": "body_detail"
-    }
-  ]
-}
-```
-
-需要我把它作为新功能（比如 P4）加入引擎吗？具体来说需要：
-
-1. `engine/types.ts` — 新增 `ImageScene` 类型和 `Hotspot` 接口
-2. `src/components/ImageHotspot.vue` — 渲染图片 + 可点击热区 + hover 高亮 + label 提示
-3. `engine/core/Engine.ts` — 支持 `type: "image"` 场景的播放逻辑
-4. `editor/components/NodeEditor.vue` — 编辑器支持图像场景类型切换 + 热区可视化编辑
-5. `public/scenes/demo.json` + 示例图片

-## User
-
-很多交互式电影游戏，在触发选择等待用户选择时，会循环播放一个视频片段，这样整个游戏体验更具有电影感，而不是像我们写的一样，视频播放结束时触发用户选择，此时画面是暂停的，只要用户做出了选择后才能继续播放下一个视频，你知道这个现象吗？
-
----
-
-## Assistant (Plan · DeepSeek V4 Pro · 27.9s)
-
-_Thinking:_
-
-The user is describing a common pattern in interactive movie games: when a choice is presented, instead of pausing on the last frame, the game loops a short video segment (like a "looping idle" clip) while waiting for the player's decision. This creates a more cinematic experience — the character might be looking around nervously, the camera might be panning slightly, etc.
-
-This is indeed a standard feature in games like:
-- Detroit: Become Human (characters breathe, look around during choices)
-- Late Shift (camera holds on character reactions)
-- The Complex (subtle looping during decision points)
-
-Let me think about how to implement this in our engine:
-
-1. **Looping Video Segments**: Each scene can define a `loopUrl` — a short video that loops seamlessly while choices are shown
-2. **Seamless Transition**: When the main video ends, smoothly transition to the looping clip
-3. **Choice Overlay**: Choices appear over the looping video
-4. **On Choice**: Stop the loop, transition to the next scene
-
-The technical approach:
-- The main video plays → ends → immediately start playing the loop video on loop
-- Or alternatively: designate the last N seconds of each video as the "choice loop zone"
-- When video reaches the loop point, set `loop=true` on the video element
-
-There are a few approaches:
-
-**Approach A: Separate loop video file**
-- Each scene can have an optional `loopVideoUrl`
-- When main video ends, seamlessly switch to loop video with `video.loop = true`
-- Pros: Clean separation, loop video can be optimized (small, seamless)
-- Cons: Requires additional video files
-
-**Approach B: Loop main video from a specific timestamp**
-- Define `loopStartTime` in scene data
-- When video ends, seek back to `loopStartTime` and set `loop = true`
-- Pros: No extra files needed
-- Cons: Need to handle the seamless seek (brief flash), harder to author
-
-**Approach C: A/B dual buffer loop**
-- When approaching choice point, preload loop video in the inactive buffer
-- When main video ends, immediately cross-fade to loop video (already buffered)
-- Loop plays until choice is made
-- Uses existing A/B buffer infrastructure
-- Pros: Smooth, uses existing VideoManager
-- Cons: Need loop video, but it's the standard approach
-
-Approach A or C is best. Let me recommend A/C (same idea — separate loop video) since it's the most common approach in games and gives the smoothest result.
-
-Let me also think about the data model:
-
-```json
-{
-  "id": "scene_1",
-  "videoUrl": "/videos/scene_1.mp4",
-  "loopVideoUrl": "/videos/scene_1_loop.mp4",
-  "choices": [
-    { "text": "救人", "targetScene": "rescue" },
-    { "text": "逃跑", "targetScene": "flee" }
-  ]
-}
-```
-
-When `loopVideoUrl` is present:
-- Play main video → ends → seamlessly switch to loop (inactive buffer, loop=true) → show choices
-- User clicks choice → stop loop → switch to target scene
-- No loopVideoUrl → current behavior (pause at end)
-
-This is clean and minimal. Should I ask the user clarifying questions first?
-
-Actually, the user is describing the concept and asking if I know about it. They seem to want to add this to the roadmap. Since we're in read-only/plan mode, I should acknowledge, explain the implementation approach, and suggest adding it to the roadmap.
-
-知道。这是交互式电影游戏的标准做法——**选择等待循环（Choice Idle Loop）**。
-
-视频播完后不暂停，而是无缝切换到一段短循环视频，画面持续"活着"（角色呼吸、张望、环境微动），选项浮在循环画面之上。玩家做出选择后，循环结束，切换到目标场景。
-
-像《底特律：变人》《Late Shift》《The Complex》都这样做。

-                                                                    │
-                                                    停止循环 → 切换到目标场景
-```
-
-**具体改动点：**
-
-| 层 | 改动 |
-|----|------|
-| `types.ts` | `SceneNode` 加 `loopVideoUrl?: string` |
-| `VideoManager.ts` | `playInitial`/`switchTo` 增加 loop 参数，或新增 `playLoop(url)` 方法（直接用 inactive buffer，`loop=true`，无缝淡入） |
-| `Engine.ts` | 视频 ended 时检测 scene 是否有 `loopVideoUrl`，有则调用 `playLoop` 而不是直接弹出选项 |
-| `ChoicePanel.vue` | 无改动（选项已经浮在视频上） |
-
-**关键：** 已有的 A/B 双缓冲让无缝切换成本极低——主视频在 A 槽结束时，循环视频已经在 B 槽预加载好了，直接 `loop=true` + 交叉淡化即可。

-
-- **SceneNode** 新增 `loopVideoUrl` 字段
-- **VideoManager** 新增 `playLoop(url)` — 复用 inactive 槽，`loop=true` + 交叉淡化
-- **Engine** — ended 时检测 loopVideoUrl，有则进入循环而非直接弹选项；选择后停止循环

-## User
-
-是否可以把背景音频独立出来播放，这样循环播放视频前端时，并不会打断背景音乐的播放，这样即使画面重复了，但是背景音乐是连贯的，让玩法更有沉浸感？其他成熟的电影游戏是这样做的吗？
-
----
-
-## Assistant (Plan · DeepSeek V4 Pro · 30.1s)
-
-_Thinking:_
-
-The user is asking about separating background audio from video, so that when a choice idle loop plays (repeating video foreground), the background music/audio continues uninterrupted. This is a great question and a common technique.
-
-Let me think about how commercial interactive movie games handle this:
-
-1. **Audio Layers**: Most game engines separate audio into layers/channels:
-   - Background music (BGM) - continuous, loops independently
-   - Ambient audio - environmental sounds
-   - Dialogue/Voice - synced to specific scenes
-   - Sound effects (SFX) - one-shot effects
-
-2. **In games like Detroit: Become Human**:
-   - The video layer may loop a character's idle animation
-   - But the background music continues its own timeline, creating tension and atmosphere
-   - When a choice is made, the music transitions (crossfades) to the next scene's music
-   - This is exactly what makes it feel cinematic - music doesn't "restart" just because you're waiting for input
-
-3. **Technical implementation**:
-   - Video files are often rendered WITHOUT background music (or with music at a much lower volume that can be replaced)
-   - The game engine plays audio tracks separately, giving full control over transitions
-   - During choice loops, the video loops but the audio engine continues playing the music track
-   - When transitioning to the next scene, there can be audio crossfading
-
-4. **How our engine would handle this**:
-   - Add an AudioSystem that manages BGM independently from VideoManager
-   - SceneNode gets `bgmUrl?: string` and `bgmVolume?: number` 
-   - When switching scenes, if the next scene has the same BGM, it continues; if different, crossfade
-   - During choice idle loop, video loops but BGM continues uninterrupted
-   - The loopVideo itself should NOT contain music (or very quiet music that can be replaced)
-
-This is definitely how mature interactive movie games work. Let me present this analysis and suggest P6.
-
-Actually, I should be careful - I'm in plan mode (read-only). I should NOT make any edits. I should just discuss and plan.
-
-Let me present the analysis to the user.
-
-是的，成熟的交互式电影游戏都是这样做的。这正是它们有"电影感"而非"播放器感"的关键原因。
-
-### 行业做法
-
-像《底特律：变人》《The Dark Pictures Anthology》等游戏，**视频和音频是分离的两个层**：
-
-- 视频画面可以因为等待选择而循环（角色喘气、张望）
-- 背景音乐是一条**独立的连续时间线**，不会因为视频循环而断掉
-- 不同场景的 BGM 之间用**交叉淡化**衔接（下一段的音乐在当前场景结束前就渐入）
-
-本质上，制作这些游戏的视频素材时，**导出的视频文件就不包含背景音乐**（或音量极低），音乐完全由引擎单独驱动。
-
-### 对比现状
-
-| | 现状（P0~P5） | 改进后 |
-|----|----|----|
-| 音频来源 | 嵌入在 mp4 视频文件里 | 独立音频文件，引擎单独播 |
-| 选择等待时 | 循环视频 → **音乐也循环断掉** | 视频循环 → **音乐继续连贯** |
-| 场景切换时 | A/B 视频交叉淡化 | 视频淡化 + 音频独立交叉淡化 |
-| 氛围控制 | 无法动态调整 | 可随时调音量、淡入淡出 |
-
-### 实现方案
-
-核心思路是给引擎加一个 **AudioManager**，与 VideoManager 平级但独立运行：
-
-```
-Engine
-├── VideoManager（A/B 双缓冲，负责画面）
-│    └── loopVideo 循环时只管画面
-└── AudioManager（独立 Audio 元素，负责 BGM）
-     └── 按场景播放/交叉淡化，不受视频循环影响
-```
-
-**SceneNode 新增字段：**
-
-```json
-{
-  "id": "tense_moment",
-  "videoUrl": "/videos/tense.mp4",           // 视频不含 BGM
-  "loopVideoUrl": "/videos/tense_loop.mp4",   // 循环画面不含 BGM
-  "bgmUrl": "/audio/tense_bgm.mp3",           // 独立 BGM
-  "bgmVolume": 0.8,
-  "bgmCrossFade": 2.0,                        // 切换时淡化秒数
-  "choices": [...]
-}
-```
-
-**AudioManager 工作流：**
-
-```
-场景 A BGM 播放中
-    │
-    ├─ 场景 A 结束，进入选择等待
-    │   视频循环 ─── 音频继续播 A 的 BGM（不受影响）
-    │
-    ├─ 用户做出选择
-    │
-    └─ 场景 B 加载
-        AudioManager 检测 BGM 变化
-            ├─ 同一音频？→ 继续播
-            └─ 不同音频？→ crossFade(A→B, 2s)
-        视频切换到 B
-```
-
-**改动清单预估：**
-
-| 层 | 改动 |
-|----|------|
-| `engine/systems/AudioSystem.ts` | 新增：独立音乐播放、交叉淡化、音量控制、循环播放 |
-| `engine/core/Engine.ts` | 集成 AudioSystem，场景切换时调度音频过渡 |
-| `engine/types.ts` | `SceneNode` 加 `bgmUrl`、`bgmVolume`、`bgmCrossFade` |
-| `engine/core/VideoManager.ts` | 音量静音选项（视频文件如含音轨，可 mute） |
-| `src/components/游戏界面` | 可选：音量滑块 UI |
-| `public/scenes/demo.json` | 示例场景拆分视频+音频 |
-| 编辑器 | NodeEditor 增加 BGM 字段 |

-- **AudioManager** 与 VideoManager 平级独立运行，场景切换对比 `bgmUrl`：同源继续、不同 crossFade
-- **视频 muted**：素材导出时就不含 BGM，或引擎层面静音视频音轨

-182: ### P4 图片热点 — 点击图片触发分支（待实现）
-183: 
-184: 目标：场景支持静态图片替代视频，图上定义可点击热区，点击不同位置触发不同分支
-185: 
-186: **场景数据设计：**
-187: 
-188: ```json
-189: {
-190:   "id": "crime_scene",
-191:   "type": "image",
-192:   "imageUrl": "/images/crime_scene.jpg",
-193:   "subtitleUrl": "/subtitles/crime_scene.vtt",
-194:   "hotspots": [
-195:     {
-196:       "id": "hs_desk",
-197:       "x": 0.15, "y": 0.25, "width": 0.18, "height": 0.12,
-198:       "label": "查看书桌",
-199:       "targetScene": "desk_detail",
-200:       "conditions": [{ "variable": "investigation", "op": ">=", "value": 1 }],
-201:       "effects": [{ "type": "setFlag", "target": "checked_desk" }]
-202:     },
-203:     {
-204:       "id": "hs_window",
-205:       "x": 0.72, "y": 0.08, "width": 0.15, "height": 0.28,
-206:       "label": "查看窗户",
-207:       "targetScene": "window_detail"
-208:     },
-209:     {
-210:       "id": "hs_body",
-211:       "x": 0.40, "y": 0.40, "width": 0.10, "height": 0.22,
-212:       "label": "检查尸体",
-213:       "targetScene": "body_detail",
-214:       "timeLimit": 10
-215:     }
-216:   ],
-217:   "choices": [
-218:     { "text": "离开现场", "targetScene": "leave_room" }
-219:   ]
-220: }
-221: ```
-222: 
-223: **字段约定：**
-224: - `type: "image"` — 声明为图片场景（默认/不存在则为视频场景）
-225: - `x/y/width/height` — 热区坐标，使用**相对比例**（0~1），自适应屏幕尺寸
-226: - 图片场景仍可同时附带底部 `choices`（如"离开"选项）
-227: - `hotspots` 支持 `conditions`（条件显隐）、`effects`（点击后效果）、`timeLimit`（限时）
-228: 
-229: **实现清单：**
-230: 
-231: - [ ] `engine/types.ts` — `SceneNode.type` 字段、`Hotspot` 接口
-232: - [ ] `engine/core/Engine.ts` — 支持 `type: "image"` 场景，挂载图片 + 热区
-233: - [ ] `src/components/ImageScene.vue` — 渲染图片 + 热区矩形 + hover 高亮 + label 浮动提示
-234: - [ ] `editor/components/NodeEditor.vue` — 场景类型切换（视频/图片）+ 热区可视化编辑（拖放矩形）
-235: - [ ] `public/scenes/demo.json` — 新增图片场景示例 + 示例图片
-236: - [ ] 验证：图片加载、热区点击触发分支、条件过滤、限时热区
-237: 
-238: ### P5 选择等待循环 — 视频结束循环播放（待实现）
-239: 
-240: 目标：视频结束后不暂停画面，而是无缝切换到一段循环视频（Idle Loop），选项浮在循环画面之上，
-241: 消除"画面静止等选择"的割裂感，提升电影感。这是《底特律：变人》《Late Shift》等商业游戏的标配做法。
-242: 
-243: **场景数据设计：**
-244: 
-245: ```json
-246: {
-247:   "id": "tense_moment",
-248:   "videoUrl": "/videos/tense.mp4",
-249:   "loopVideoUrl": "/videos/tense_loop.mp4",
-250:   "choices": [
-251:     { "text": "冒险救人", "targetScene": "rescue" },
-252:     { "text": "悄悄离开", "targetScene": "flee" }
-253:   ]
-254: }
-255: ```
-256: 
-257: **工作流程：**
-258: 
-259: ```
-260: 主视频 A槽播放 ──→ ended ──→ B槽切换 loopVideo (loop=true) + 淡入 ──→ 显示选项
-261:                                                                           │
-262:                                                           用户点击选择 ────┘
-263:                                                                           │
-264:                                                      停止循环 → 切换到目标场景
-265: ```
-266: 
-267: **实现清单（基于现有 A/B 双缓冲架构，改动量小）：**
-268: 
-269: - [ ] `engine/types.ts` — `SceneNode.loopVideoUrl?: string`
-270: - [ ] `engine/core/VideoManager.ts` — `playLoop(url)` 新方法（复用 inactive 槽，`loop=true` + 交叉淡化）
-271: - [ ] `engine/core/Engine.ts` — 视频 ended 时检测 `loopVideoUrl`，有则调用 `playLoop` 而非直接触发选项；用户选择后停止循环
-272: - [ ] `src/components/ChoicePanel.vue` — 无改动（选项已浮在视频层之上）
-273: - [ ] `public/scenes/demo.json` — 示例场景添加循环视频
-274: - [ ] 验证：主视频结束 → 无缝循环 → 选项中循环播放 → 选择后停止 → 下一场景
-275: 
-276: ### P6 独立背景音乐 — 画面循环不打断 BGM（待实现）
-277: 
-278: 目标：将背景音乐从视频中剥离，由独立 AudioManager 驱动。视频循环/切换时 BGM 保持连贯播放，
-279: 不同场景之间用交叉淡化衔接。这也是《底特律：变人》《The Dark Pictures Anthology》等商业游戏的标配。
-280: 
-281: **架构变更：**
-282: 
-283: ```
-284: Engine
-285: ├── VideoManager（A/B 双缓冲，只管画面和视频内音轨）
-286: │    └── loopVideo 循环时只管画面 → BGM 不受影响
-287: └── AudioManager（独立 AudioContext/HTMLAudioElement，只管 BGM）
-288:      └── 按场景播放/交叉淡化/循环，独立于视频生命周期
-289: ```
-290: 
-291: **场景数据设计：**
-292: 
-293: ```json
-294: {
-295:   "id": "tense_moment",
-296:   "videoUrl": "/videos/tense_no_bgm.mp4",
-297:   "loopVideoUrl": "/videos/tense_loop_no_bgm.mp4",
-298:   "bgmUrl": "/audio/tense_bgm.mp3",
-299:   "bgmVolume": 0.8,
-300:   "bgmCrossFade": 2.0,
-301:   "bgmContinue": true,
-302:   "videoMuted": true,
-303:   "choices": [...]
-304: }
-305: ```
-306: 
-307: **工作流对比：**
-308: 
-309: | 阶段 | 改进前 | 改进后 |
-310: |------|--------|--------|
-311: | 主视频播放 | 视频自带 BGM | AudioManager 独立播 BGM，视频 muted |
-312: | 进入选择等待 | 循环视频 → BGM 断掉重来 | 视频循环 → BGM 继续连贯 |
-313: | 选择后切场景 | 下一段视频 BGM 硬切 | BGM 交叉淡化过渡（bgmCrossFade 秒） |
-314: | 关音乐/调音量 | 无法控制 | AudioManager 提供音量/静音接口 |
-315: | 同一 BGM 多场景 | 每个 mp4 嵌一份，浪费 | 共用同一文件，节省带宽 |
-316: 
-317: **实现清单：**
-318: 
-319: - [ ] `engine/systems/AudioSystem.ts` — 新增：BGM 播放、交叉淡化（GainNode ramp）、循环、音量/静音
-320: - [ ] `engine/core/Engine.ts` — 集成 AudioSystem；场景切换时对比 bgmUrl，同源→继续，不同→crossFade
-321: - [ ] `engine/types.ts` — `SceneNode` 加 `bgmUrl`、`bgmVolume`、`bgmCrossFade`、`bgmContinue`、`videoMuted`
-322: - [ ] `engine/core/VideoManager.ts` — 支持 `muted` 参数（视频音轨静音但在 BGM 模式下禁用）
-323: - [ ] `public/scenes/demo.json` — 示例场景拆分视频+音频
-324: - [ ] `editor/components/NodeEditor.vue` — BGM 字段编辑面板
-325: - [ ] 验证：BGM 跨越视频循环连续播放、场景切换交叉淡化、音量控制生效
-326: 
-327: ## 依赖清单
-328: 
-329: ```json
-330: {
-331:   "dependencies": {
-332:     "vue": "^3.4",
-333:     "pinia": "^2.1",
-334:     "@vue-flow/core": "^1.x",
-335:     "@vue-flow/background": "^1.x",
-336:     "@vue-flow/controls": "^1.x",
-337:     "dexie": "^4.0"
-338:   },
-339:   "devDependencies": {
-340:     "@vitejs/plugin-vue": "^5.0",
-341:     "typescript": "^5.3",
-342:     "vite": "^5.0",
-343:     "vue-tsc": "^2.0"
-344:   }
-345: }
-346: ```
-347: 
-348: ## 关键架构决策记录
-349: 
-350: 1. **引擎与 UI 分离**: `engine/` 下纯 TS 类，不 import Vue。UI 层通过 composables 桥接。
-351: 2. **A/B 双缓冲**: 两个 `<video>` 元素轮换，一个播放时另一个预加载候选视频。
-352: 3. **JSON 驱动**: 所有剧情数据放在 JSON 中，编辑器本质是 JSON 的可视化读写工具。
-353: 4. **IndexedDB 存档**: 比 localStorage 容量大，可存储截屏缩略图。

-## Assistant (Plan · DeepSeek V4 Pro · 54.1s)
-
-_Thinking:_
-
-Now I have a complete picture of P0-P6. Let me comprehensively analyze what we have vs. what mature interactive movie games have. Let me think about industry-standard features:
-
-**What we have (P0-P6):**
-- P0: Basic video playback + choices + branching
-- P1: A/B seamless switching + conditions + save/load
-- P2: QTE + subtitles + save thumbnails
-- P3: Visual editor
-- P4 (planned): Image hotspots
-- P5 (planned): Choice idle loop
-- P6 (planned): Independent BGM
-
-**What mature interactive movie games have that we're missing:**
-
-### 1. 剧情回顾 / 关系图 (Relationship/Choice Map)
-Games like Detroit: Become Human show a flowchart at the end of each chapter showing all the paths taken and not taken. Players can see the "what if" moments.
-
-### 2. 章节选择 (Chapter Select)
-After completing a chapter, players can replay it from any checkpoint. This is crucial for replayability - players want to explore different branches without replaying the entire game.
-
-### 3. 关键选择高亮 / 道德系统 (Moral/Consequence System)
-Some choices are "critical" - they flash, have special effects, or show a tension meter. Telltale games: "[Character] will remember that." The game tracks morality/alignment.
-
-### 4. 倍速 / 跳过功能 (Skip/Fast Forward)
-HandBrake style: skip already-seen scenes, or speed up replay. This is critical for replayability - nobody wants to re-watch the same 5-minute unskippable video 10 times.
-
-### 5. 全屏模式 / 沉浸模式 (Fullscreen Mode)
-Essential for browser games. F11 fullscreen, pointer lock, hiding UI during video.
-
-### 6. 多语言支持 (i18n/Localization)
-Multiple subtitle tracks, UI language switching. This is table stakes for any game that wants international distribution.
-
-### 7. 成就系统 (Achievement System)
-Unlock achievements for discovering specific endings, making certain choices, etc. This drives replayability.
-
-### 8. 可访问性 (Accessibility)
-- Subtitle styling options (size, background, color)
-- High contrast mode
-- Audio descriptions for the visually impaired
-
-### 9. 视频质量自适应 (Adaptive Streaming)
-DASH/HLS adaptive bitrate - auto-switch quality based on bandwidth. Critical for web-based distribution where users have varying internet speeds.
-
-### 10. 拖拽进度条 / 快进快退 (Seek/Scrub)
-Ability to jump forward or backward in a scene (especially during replay).
-
-### 11. 统计面板 (Statistics Panel)
-At the end, show global stats: "73% of players chose to save the girl", "You found 3/5 hidden clues". This is very common in Telltale/Quantic Dream games.
-
-### 12. 氛围效果 (Ambient Effects)
-- Screen shake
-- Color grading / vignette effects during intense moments
-- Flash effects
-
-### 13. 对话历史 (Dialogue Log)
-Scroll back to see past dialogue, like a chat log.
-
-### 14. 计时挑战模式 (Timed Challenge Mode)
-A game mode where ALL choices are timed (not just QTE).
-
-### 15. 导演评论模式 (Director's Commentary)
-Like DVD commentary - optional voiceover track explaining design decisions.
-
-### 16. 多结局画廊 (Ending Gallery)
-Show which endings you've unlocked and which are still locked, with unlock conditions.
-
-### 17. 控制器支持 (Gamepad Support)
-Support for gamepad navigation (d-pad to select choices, button to confirm). Essential for "lean back" experience.
-
-### 18. 过场动画跳过确认 (Skip Confirmation)
-"Press any key to skip" with a visual indicator, preventing accidental skips.
-
-### 19. 自动保存 / 检查点 (Checkpoint Auto-save)
-Already have basic save, but checkpoint system is more granular - the game auto-saves at the start of every scene, not just on manual save.
-
-### 20. 云存档 (Cloud Save)
-Sync saves across devices. For web, this would be authenticated server-side storage.
-
-### 21. 场景过渡特效 (Transition Effects)
-Beyond cross-fade: wipes, cuts, fades to black/white, custom transitions between scenes.
-
-### 22. 对话轮系统 (Dialogue Wheel)
-Instead of just text buttons, a radial dialogue wheel (like Mass Effect or Telltale) for selection UI.
-
-### 23. 动态字幕 (Dynamic Subtitles)
-Subtitles with speaker name, color-coded by character, subtitle positioning per-speaker.
-
-### 24. 环境音效 (SFX Layer)
-Beyond BGM - separate sound effects layer (door creaks, footsteps, ambient hum). Independently controllable.
-
-### 25. 角色语音独立轨道 (Voice Track)
-Separate voice acting from BGM and SFX, allowing language switching for voice.
-
----
-
-Now let me think about which of these are MOST important for a web-based interactive movie game. Some are complex server-side features that may be out of scope. Others are core to the experience.
-
-Let me categorize by priority:
-
-**Critical (almost expected by players):**
-1. 全屏模式 (Fullscreen) - essential for browser games
-2. 章节选择 (Chapter Select) - core replayability
-3. 跳过已看内容 (Skip/Fast Forward) - critical for replay
-4. 控制器 / 键盘导航支持 - "lean back" experience
-5. 多语言字幕 (i18n) - localization
-6. 场景过渡特效 - polish
-
-**High value:**
-7. 成就系统
-8. 统计面板 (global choice stats)
-9. 关键选择高亮 ("X will remember that")
-10. 剧情回顾流程图
-11. 结局画廊

-Let me present a well-organized analysis.
-
-对比业界成熟的交互式电影游戏（《底特律：变人》《The Dark Pictures Anthology》《Late Shift》《Telltale 系列》），P0~P6 覆盖了核心交互层，但还缺一批重要功能。按优先级分：
-
----
-
-## 缺失功能分析
-
-### 第一梯队：玩家基本预期（缺了会被骂）
-
-| 功能 | 现状 | 业界做法 |
-|------|------|----------|
-| **全屏模式** | 无，始终窗口 | F11 全屏 + 指针锁定 + 播放中隐藏 UI，浏览器游戏标配 |
-| **章节选择** | 无，只能从头打 | 通关后解锁章节入口，直接跳转到该章节起始场景 |
-| **跳过已看** | 无，每次重打都要看完所有视频 | "已看场景可跳过" 或 2x 倍速，重玩探索分支的核心体验 |
-| **键位/手柄导航** | 仅鼠标点按钮 | 方向键/WASD 选选项 + 回车确认 + Space 跳过，适配"躺沙发"体验 |
-| **多语言字幕** | 字幕固定，无语言切换 | i18n 字幕轨道，支持中/英/日等切换 |
-| **场景过渡特效** | 仅 opacity 交叉淡化 | 淡黑（fade to black）、白闪、模糊切换等，电影转场语言 |
-
-### 第二梯队：重玩驱动（增加游戏寿命）
-
-| 功能 | 业界做法 |
-|------|----------|
-| **关键选择提示** | "[某人] 会记住这件事" — Telltale 的经典做法，让玩家感知选择的重量 |
-| **结局画廊** | 展示所有结局及解锁状态，显示解锁条件（类似《底特律》的流程图） |
-| **成就系统** | "解锁全部结局"、"在一次都没死的情况下通关"、"找到 5 个隐藏线索" |
-| **全局统计** | 通关后显示 "73% 玩家选择了救人"、"你找到了 3/5 个线索" |
-| **剧情回顾** | 章节结束后显示当前章节的流程分支图，走过的路径高亮 |
-
-### 第三梯队：沉浸感与表现力
-
-| 功能 | 业界做法 |
-|------|----------|
-| **音效层 (SFX)** | BGM 之外独立的音效轨道：门响、脚步、环境声，可单独控音量 |
-| **对话轮 UI** | 圆形/半圆形对话轮（比列表按钮更有主机游戏感），选项按方向布局 |
-| **氛围特效** | 紧张时刻的画面震动、暗角、色彩偏移（靠 CSS filter 可实现） |
-| **动态字幕** | 说话人名字前缀 + 角色颜色区分 + 字幕位置随说话人偏移 |
-| **自适应码率** | HLS/DASH 自动切画质，网络差时降低码率不卡顿（浏览器原生支持） |
-
-### 第四梯队：锦上添花
-
-| 功能 |
-|------|
-| 云存档（需后端） |
-| 可访问性（字幕大小/背景色/高对比度） |
-| 导演评论音轨 |
-| 对话历史回溯 |
-| 拖拽进度条（与交互叙事冲突，谨慎） |

-## 建议
-
-**P7~P10 优先补第一梯队：** 全屏 + 章节选择 + 跳过/倍速 + 键位导航 + 多语言，这 5 项缺了会让玩家觉得"不像个正经游戏"。
-
-**P11~P15 第二梯队**对重玩率提升巨大，尤其是结局画廊和全局统计。
-
-你觉得哪些优先进入 ROADMAP？或者你来排一下 P7 到 P15 的顺序？

-The user wants me to add all the missing features (P7 through P15) to the ROADMAP.md file. Let me organize them into phases as discussed, with proper descriptions, implementation details, and scene data designs where applicable.
-
-Let me write P7 through P15 into the roadmap after P6.

-320: - [ ] `engine/core/Engine.ts` — 集成 AudioSystem；场景切换时对比 bgmUrl，同源→继续，不同→crossFade
-321: - [ ] `engine/types.ts` — `SceneNode` 加 `bgmUrl`、`bgmVolume`、`bgmCrossFade`、`bgmContinue`、`videoMuted`
-322: - [ ] `engine/core/VideoManager.ts` — 支持 `muted` 参数（视频音轨静音但在 BGM 模式下禁用）
-323: - [ ] `public/scenes/demo.json` — 示例场景拆分视频+音频
-324: - [ ] `editor/components/NodeEditor.vue` — BGM 字段编辑面板

-347: 
-348: ## 关键架构决策记录
-349: 
-350: 1. **引擎与 UI 分离**: `engine/` 下纯 TS 类，不 import Vue。UI 层通过 composables 桥接。
-351: 2. **A/B 双缓冲**: 两个 `<video>` 元素轮换，一个播放时另一个预加载候选视频。
-352: 3. **JSON 驱动**: 所有剧情数据放在 JSON 中，编辑器本质是 JSON 的可视化读写工具。
-353: 4. **IndexedDB 存档**: 比 localStorage 容量大，可存储截屏缩略图。

+The edit also removed AchievmentPanel which I need to add back. Let me check and fix.
+
+Actually wait — looking at the replacement, the oldString contained AchievementPanel too but I removed it. Let me check.
+
+Looking at the replacement more carefully, the oldString had:
+1. ChapterSelect block
+2. AchievementPanel block
+3. EndingGallery block
+4. ChapterRecap block
+
+And newString has:
+1. StoryGallery block
+2. ChapterRecap block
+
+But the ChapterRecap block is still needed? Actually per P22 design, ChapterRecap's logic is embedded into StoryGallery (inline recap on card click). The standalone ChapterRecap.vue is no longer needed as a separate modal. But I still have it in the newString. Let me remove it.
+
+Also I need to add AchievementPanel back since it was removed. Let me also remove the now-unused `recapChapterId`, `showChapterSelect`, `showEndingGallery` state refs, and their handlers from the script section.
+
+Actually, let me keep recapChapterId for now since ChapterRecap is still referenced. But per P22, it should be removed. Let me do a clean removal.
+
+Wait, I should also remove AchievementPanel from the old — I removed it by accident in the oldString but it should stay. Let me fix.
+
+Let me also add showStoryGallery state and remove unused states. Let me read the current template to see what was actually replaced.

+
+## Assistant (Plan · DeepSeek V4 Pro · 21.0s)
+
+_Thinking:_
+
+The user is reporting a bug: hotspot labels don't support i18n language switching. Let me analyze the current implementation.
+
+Hotspot has a `label` field that's displayed when hovering over a hotspot. Currently this is a plain string. We need to add i18n support similar to how Choice.textKey works.
+
+Looking at the current Hotspot interface in types.ts:
+```typescript
+export interface Hotspot {
+  id: string
+  label: string
+  targetScene: string
+  // ... other fields
+}
+```
+
+And in HotspotLayer.vue, the label is displayed directly:
+```html
+<span class="hotspot-label">{{ hs.label }}</span>
+```
+
+The fix needs two parts:
+1. Add `labelKey?: string` to the Hotspot interface in `engine/types.ts`
+2. Update `HotspotLayer.vue` to use `t(hs.labelKey || hs.label)` instead of just `hs.label`
+
+This mirrors exactly how Choice.textKey works. Let me check how Choice text is handled in the composable... It's translated in useGameEngine.ts's `choiceRequest` handler. But hotspots don't go through the engine event system for labels — they're displayed directly by HotspotLayer.vue.
+
+So the simplest fix is to make HotspotLayer.vue use the i18n `t()` function directly, mirroring the pattern used for Choice buttons.
+
+Plan:
+1. `engine/types.ts` — Add `labelKey?: string` to Hotspot interface
+2. `src/components/HotspotLayer.vue` — Import `useI18n`, use `t(hs.labelKey || hs.label)`
+3. `public/scenes/demo.json` — Add `labelKey` to one or two hotspots as examples
+4. `src/locales/zh.json` + `en.json` — Add hotspot label translations
+
+This is a small fix — about 10 lines of code across 4 files.
+
+问题确认：`Hotspot.label` 是硬编码字符串，不支持语言切换。修复方案和 `Choice.textKey` 完全一致：
+
+### 改动计划
+
+| 文件 | 改动 |
+|------|------|
+| `engine/types.ts` | `Hotspot` 加 `labelKey?: string` |
+| `src/components/HotspotLayer.vue` | `{{ hs.label }}` → `{{ t(hs.labelKey \|\| hs.label) }}` |
+| `src/locales/zh.json` + `en.json` | 新增 `scene.crime_scene.hotspot.*` 翻译 key |
+| `public/scenes/demo.json` | 1-2 个热点加上 `labelKey` 示例 |
+
+**总改动：~15 行代码，4 个文件。** 需要退出只读模式后执行。

+Done. Hotspot labels now support i18n via `labelKey` field, same as Choice.textKey. Changes:
+
+1. `engine/types.ts` — `Hotspot.labelKey?: string`
+2. `src/components/HotspotLayer.vue` — `t(hs.labelKey || hs.label)` for label and title
+3. `src/locales/*.json` — Added scene investigation_site hotspot translations
+4. `public/scenes/demo.json` — 3 hotspots with labelKey examples
+
+完成。4 个文件改动：
+
+- `engine/types.ts` — `Hotspot.labelKey?: string`
+- `src/components/HotspotLayer.vue` — label 和 title 用 `t(hs.labelKey \|\| hs.label)` 翻译
+- `src/locales/zh.json` + `en.json` — 新增 `scene.investigation_site.hotspot.*` 翻译 key
+- `public/scenes/demo.json` — 3 个热点加了 `labelKey` 示例

+## Assistant (Plan · DeepSeek V4 Pro · 13.8s)
+
+_Thinking:_
+
+The user is saying I made a mistake. The game story texts (scene-specific translations) should be in `public/locales/`, while `src/locales/` should only contain UI text translations.
+
+Let me understand the architecture:
+- `src/locales/` — UI only (buttons, labels, menus, settings)
+- `public/locales/` — Scene/story text (choices, hotspots, subtitles etc.)
+
+So the hotspot translations I added to `src/locales/zh.json` and `en.json` should be moved to `public/locales/`. And the composition API `useI18n` needs to merge translations from both sources — or have a separate mechanism for scene-level i18n.
+
+Let me check how the current i18n system works — specifically how choice translations are handled via `textKey`. The `useI18n` composable loads from `src/locales/`. But if scene texts should be in `public/locales/`, we need a way to load those dynamically at runtime.
+
+Let me read the current useI18n.ts and understand the existing pattern for story locale loading.
+

+
+_Thinking:_
+
+Now I understand the architecture clearly:
+
+1. `src/locales/*.json` — Static UI text, bundled at build time via Vite import
+2. `public/locales/*.json` — Story/scene text, loaded dynamically at runtime via `fetch()`. The path is configured by `demo.json`'s `locales.path` field (e.g., `"locales/path": "locales/"` which maps to `public/demo/locales/`)
+
+The `t(key)` function:
+1. First checks `storyMessages` (loaded from `public/locales/`)
+2. Falls back to `uiMessages` (imported from `src/locales/`)
+
+So the hotspot translations I added to `src/locales/zh.json` and `en.json` should instead be in the story locale files at `public/demo/locales/zh.json` and `public/demo/locales/en.json`.
+
+Let me check what's already in those files:
+- `public/demo/locales/zh.json`
+- `public/demo/locales/en.json`
+
+I need to:
+1. Remove the `scene.investigation_site.hotspot.*` entries from `src/locales/zh.json` and `src/locales/en.json`
+2. Add them to `public/demo/locales/zh.json` and `public/demo/locales/en.json` instead
+
+Let me check what's currently in the story locales.

+
+Good. Now let me check how scene-level translations are currently used. The `useI18n.ts` `t()` function first checks storyMessages (loaded from `public/locales/`), then falls back to UI messages (from `src/locales/`). So the correct fix is:
+
+1. Remove hotspot translations from `src/locales/zh.json` and `en.json` (I incorrectly added them there)
+2. Add them to `public/demo/locales/zh.json` and `en.json` (the story locale files)
+
+But I'm in plan mode — I can't make edits. Let me present the plan and wait for execution.
+
+明白了。当前架构是：
+
+| 位置 | 内容 | 加载方式 |
+|------|------|---------|
+| `src/locales/` | **UI 文本**（按钮、菜单、设置） | Vite 静态 import，构建时打包 |
+| `public/demo/locales/` | **故事文本**（选项文字、热点标签、字幕） | 运行时 `fetch()`，`useI18n.t()` 优先查故事消息，fallback 到 UI 消息 |
+
+我刚才错误地把热点翻译写入了 `src/locales/`。需要修正：
+
+### 修正计划
+
+| 操作 | 文件 |
+|------|------|
+| **删除** `scene.investigation_site.hotspot.*` | `src/locales/zh.json`、`src/locales/en.json` |
+| **写入** 同样的 hotspot 翻译 | `public/demo/locales/zh.json`、`public/demo/locales/en.json` |

+_Thinking:_
+
+The user is pointing out that the `labelKey` values in demo.json use `"scene.investigation_site.hotspot.desk"` but the actual locale files at `public/demo/locales/zh.json` use the key `"investigation_site.hotspot.desk"` (without the `"scene."` prefix).
+
+Looking at the story locale files:
+```json
+// public/demo/locales/zh.json
+{
+  "investigation_site": {
+    "hotspot": {
+      "desk": "查看书桌"
+    }
+  }
+}
+```
+
+But demo.json has:
+```json
+"labelKey": "scene.investigation_site.hotspot.desk"
+```
+
+The `useI18n.t()` function splits by "." and traverses the JSON. So `t("scene.investigation_site.hotspot.desk")` would try to find `storyMessages[lang].scene.investigation_site.hotspot.desk` — but the actual JSON structure is `storyMessages[lang].investigation_site.hotspot.desk` (no `scene` prefix).
+
+So I need to change the `labelKey` values in demo.json from `"scene.investigation_site.hotspot.*"` to `"investigation_site.hotspot.*"`.
+
+Same issue with the Choice `textKey` values — they also don't have a `"scene."` prefix in the locale files. For example, the locale file has `"intro.choice.left_door"` and the demo.json has `"textKey": "intro.choice.left_door"` — without `scene.` prefix. So choices are correct, only the hotspot labelKeys are wrong.
+
+Let me fix the three labelKey values in demo.json.
+
+`labelKey` 多了 `scene.` 前缀。故事 locale JSON 的结构是 `investigation_site.hotspot.desk`，不是 `scene.investigation_site.hotspot.desk`。

+1226: 渲染层：  投影函数 f(graph, playerState) → 玩家树（Tree）→ UI 展示
+1227: ```
+1228: 
+1229: 创作者只维护一份故事图数据，发布的也是图数据。玩家端展示逻辑中实时将故事图拆解为严格树来展示。
+1230: 
+1231: **关键设计决策：玩家树不展示汇聚。**
+1232: 
+1233: 对标 Detroit: Become Human——即使创作图中多条路径最终合流到同一场景，玩家树中也复制为独立节点，展示为独立分支。目的是让玩家感觉每个选择都开辟了独特的道路，不暴露"你的选择其实殊途同归"。
+1234: 
+1235: **投影转换规则：**
+1236: 
+1237: | 图中结构 | 树中处理方式 |
+1238: |----------|-------------|
+1239: | 剧情节点 | 保留，标记已访问/未探索/锁定 |

+1244: | 结局节点 | 保留，未达成时显示"???" |

+1246: | 环（循环/重选/死亡重来） | 消解：不体现或合并 |
+1247: | 汇聚（多路径合并到同一场景） | 复制节点为独立分支，维持严格树形结构 |
+1248: 
+1249: **例外：** 若"循环"本身是叙事主题（时间循环类故事），可在玩家树中保留，但建议用螺旋图等特殊可视化替代传统树形图。
+1250: 
+1251: **设计优势：**
+1252: 
+1253: 1. **单一数据源（Single Source of Truth）** — 只维护故事图，避免两套数据不一致
+1254: 2. **零创作负担** — 创作者无需关注玩家树，专注故事图即可
+1255: 3. **灵活渲染** — 不同展示策略只改前端投影逻辑，不影响数据层
+1256: 4. **实时更新** — 玩家每做一次选择，重新投影即可刷新玩家树
+1257: 5. **选择分量感** — 严格树 + 不展示汇聚，每条路径看起来都是独立故事线

+## Assistant (Plan · DeepSeek V4 Pro · 20.6s)
+
+_Thinking:_
+
+Now I have the full P23 content. Let me analyze it:
+
+P23 is an **architecture design document** rather than a feature implementation plan. It describes the distinction between:
+
+1. **Story Graph (创作端)** — the full directed graph that the creator writes in JSON (scenes with choices, conditions, QTE, etc.). This is the data.
+2. **Player Tree (玩家端)** — a strict tree projected from the graph for display to the player. The tree has no cycles, no merges, and is derived at runtime.
+
+The P23 describes:
+- Graph-to-tree projection rules
+- Design philosophy: "Graph is data, Tree is view"
+- How Detroit handles merges (duplicate nodes in tree)
+- Advantages of this architecture
+
+Now let me evaluate whether this P23 fits the current project:
+
+**Problems with P23:**
+
+1. **Not an implementable feature** — P23 is an architecture philosophy, not a concrete feature with files to change and tasks to complete. It lacks an implementation checklist.
+
+2. **The projection rules are hypothetical** — Lines 1237-1247 describe rules like "跳过条件判断节点", "跳过变量赋值节点", "AI 生成指令节点", "连续线性剧情合并为单个章节节点". Our engine doesn't have "AI 生成指令节点" or "连续线性剧情合并" concepts. These rules don't map to anything in the current codebase.
+
+3. **No concrete user-facing change** — Unlike P0-P22 which all describe specific features (P18: error recovery, P19: packaging, P20: intro video, etc.), P23 is a theoretical framework.
+
+4. **The "strict tree" projection is already implicitly done** — Our ChapterRecap/StoryGallery already uses BFS from a chapter's startScene to project a reachable subgraph. The "tree vs graph" distinction is already achieved by the BFS traversal that builds a tree of visited/unvisited paths. We don't duplicate merge nodes — that's a future enhancement, not the core.
+
+5. **Misplaced dependencies section** — Lines 1259-1276 repeat the dependencies JSON that's already at the top of the file.
+
+**How to reorganize P23:**
+
+Option A: Move the architecture philosophy to the "关键架构决策记录" section at the bottom of ROADMAP.md (lines 1278-1283). Remove it as a numbered P item.
+
+Option B: Keep it as P23 but add a concrete implementation checklist. For example, what does "implement the projection rules" actually mean in terms of code changes?
+
+Option C: Move it to FUTURE.md as an architecture note, since it's more of a design principle than an incremental feature.
+
+**My recommendation:**
+
+P23 should be split:
+1. The architecture principle ("Graph is data, Tree is view") → add to the "关键架构决策记录" section at the bottom
+2. The projection rules and design advantages → move to a new `docs/ARCHITECTURE.md` or FUTURE.md
+3. Delete P23 as a numbered feature item (or replace with a concrete feature if one exists)
+
+The current P23 is well-written as a design document but doesn't fit the ROADMAP pattern of "objective + data design + implementation checklist + verification".
+
+I'm in plan mode so I can only discuss.
+
+P23 写得很清楚，但**不应该是一个 P**。它是一份架构设计文档，而不是一个可执行的功能任务。
+
+### 问题
+
+| 问题 | 说明 |
+|------|------|
+| **没有实现清单** | P0~P22 都有"改动哪些文件 + 具体做什么"，P23 没有 |
+| **规则不匹配当前引擎** | 表中 "AI 生成指令节点""连续线性剧情合并为单个章节节点" — 我们的引擎没有这些概念 |
+| **投影逻辑已经存在** | BFS 遍历（ChapterRecap/StoryGallery）已经是 graph → tree 的投影。汇聚节点复制是未实现的增强，不是核心 |
+| **和依赖清单冲突** | 1273 行把 package.json 又抄了一遍，和全文档开头的重复 |
+
+### 建议拆分
+
+| 内容 | 放到哪里 |
+|------|---------|
+| "故事图是数据，玩家树是视图" 架构原则 | ROADMAP 底部"**关键架构决策记录**"第 5 条 |
+| 投影转换规则 + 设计优势（1247-1257 行） | `FUTURE.md` 或新建 `docs/ARCHITECTURE.md` |
+| 视频加载失败恢复 | 保持为 P18（ROADMAP 已有） |
+| 依赖清单重复 | 删除 1273-1283 行 |
+
+### 改后效果
+
+P23 从 ROADMAP 中移除，架构决策移到底部。同时把 P18 放在 P22 之后、P23 位置补一个真正可执行的功能。

+
+讨论一下P23

+
+## Assistant (Plan · DeepSeek V4 Pro · 20.3s)
+
+_Thinking:_
+
+The user wants to discuss P23. Let me re-read it carefully and provide a thorough analysis.
+
+P23 is titled "故事图与玩家树架构 — 图为数据，树为视图" (Story Graph and Player Tree Architecture — Graph as Data, Tree as View).
+
+Looking at this from a high level: P23 is an architecture philosophy document that proposes a distinction between the creator's story graph and the player's experience as a tree. Let me think about whether this belongs in the roadmap at all, and what value it adds.
+
+Key points from P23:
+1. Creator-side: directed graph (can have cycles and merges)
+2. Player-side: strict tree (no cycles, no merges, each node has one parent)
+3. Principle: "Story graph is data, player tree is view"
+4. Projection function: f(graph, playerState) → tree
+5. Design choice: don't show merges in the player tree (even if multiple paths converge to the same scene)
+
+What P23 is really about:
+- It's a **display philosophy for the chapter recap / story progress feature** (P15/P22)
+- When showing the player their progress through a chapter, should we show the full graph (with merges/convergence) or a simplified tree?
+- Detroit's approach: duplicate merged nodes in the tree so each branch looks independent
+
+The question is: is this a separate feature (P23) or a refinement of existing features (P15/P22)?
+
+I think this is more of an architecture note / design principle than a standalone feature. It doesn't introduce new files or components — it's a guiding principle for how existing features (ChapterRecap, StoryGallery) should display data.
+
+Let me think about what the user might want to discuss:
+1. Whether P23 should be a numbered roadmap item
+2. Whether the graph→tree projection is useful for the current engine
+3. What concrete implementation it would require
+4. Where this design philosophy should live in the documentation
+
+Let me give a thoughtful response.
+
+P23 的核心思想是**对的**，但它本质上不是 P，而是一个**设计原则**。让我拆解：
+
+---
+
+### P23 真正在说什么
+
+两个字：**Display 规则**。当 StoryGallery 的章节回顾中展示分支结构时，图中的汇聚节点（两个选择合流到同一场景）怎么画？
+
+```
+创作图（JSON 中实际存在的）：
+  A → B → D
+  A → C → D     ← D 是两个分支的汇聚点
+```
+
+```
+Detroit 式玩家树（展示给玩家的）：
+  A → B → D₁
+  A → C → D₂    ← D 被复制，看起来像两条完全不同的路线
+```
+
+P23 的价值在于**回答了这个 display 问题**。它不是要新建文件或增删代码，而是定义已有功能（StoryGallery/ChapterRecap）的**展示策略**。
+
+---
+
+### 它不应该是一个独立的 P
+
+因为它没有 "文件改动清单"。现有的 StoryGallery 和 ChapterRecap 已经能展示场景列表——P23 只是在说 "当多条路径合流时，应该复制节点保持树形结构"。这是对已有组件的 refine，不是新功能。
+
+---
+
+### 建议处理方式
+
+| 内容 | 位置 |
+|------|------|
+| "Story graph is data, player tree is view" | ROADMAP 底部"关键架构决策记录"第 5 条，~5 行 |
+| 投影转换规则表（1237-1247 行） | `FUTURE.md` → 注明"StoryGallery 展示策略——汇聚节点的处理" |
+| 设计优势（1251-1257 行） | 可以保留在决策记录中作为理由 |
+
+这样 ROADMAP 的 P23 可以改为一个**真正可执行的功能**（如 P18 视频加载失败恢复，或一个新的 feature），架构原则归入架构记录。
+
+---
+
+你觉得这个处理方式合适吗？还是你希望 P23 保持为独立的文档条目？

+## User
+
+我想实现P23,梳理一下改动，像其他的P一样
+
+---
+
+## Assistant (Plan · DeepSeek V4 Pro · 40.2s)
+
+_Thinking:_
+
+The user wants me to turn P23 from an architecture philosophy document into an actual implementable feature with concrete file changes and tasks. Let me think about what P23 would actually do to the codebase.
+
+The core idea: In the StoryGallery/ChapterRecap, when displaying the scene list for a chapter, if multiple paths converge to the same scene, we should show that scene as separate entries for each incoming path (like Detroit does).
+
+Currently, our BFS traversal in StoryGallery just collects all reachable scenes into a flat list. We don't track which path leads to which scene. To implement "duplicate nodes for converging paths", we'd need to:
+
+1. Change the BFS traversal to build a tree instead of a flat set
+2. In the tree, each occurrence of a scene has a "path prefix" (the sequence of scenes that led to it)
+3. The UI shows each occurrence as independent, with its own visited status (based on whether the player actually arrived via that specific path)
+
+But wait — our visitedSceneIds is just a flat Set of scene IDs. We don't track "which path" the player took to reach a scene. So for the "converging paths" feature, we'd need:
+- A new data structure: `visitedEdges` or `pathHistory` that tracks the exact path the player took
+- Or a way to derive the path from `stateManager.history`
+
+Let me think about what the minimal implementation would be:
+
+**Option A: Path-based tree projection** (heavy)
+- Track the full player path through scenes
+- Build a tree from the graph based on paths
+- Show duplicate scenes for converging paths
+- Requires: path tracking in Engine, new data structure, UI changes
+
+**Option B: Flat list with path labels** (light)
+- Keep the current flat scene list in StoryGallery
+- Add a column showing "arrived via: path label" for each scene
+- Visited status based on player's actual path
+- Requires: path tracking in Engine
+
+**Option C: Tree visualization** (medium)
+- Use Vue Flow to render the chapter's reachable subgraph as a tree
+- Nodes that are visited are green, unvisited are gray
+- Converging nodes are duplicated in the tree view
+- This replaces the current flat scene list with a proper tree diagram
+
+Actually, let me re-read what P23 is actually describing:
+
+P23 describes a distinction between:
+1. **Story Graph** — the JSON the creator writes (with all scenes, choices, conditions). This is the single source of truth.
+2. **Player Tree** — what's shown to the player. It's derived from the story graph + player's visited state. Nodes may be duplicated if multiple paths converge to the same scene.
+
+The implementation would be:
+1. Add a `buildPlayerTree(graph, startScene, visitedSceneIds, stateManager)` function
+2. This function does BFS from the start scene but instead of a flat set, it builds a tree structure
+3. Converging nodes are duplicated (each occurrence is a separate tree node)
+4. The StoryGallery/ChapterRecap uses this tree instead of the current flat scene list
+5. Each tree node knows: its scene, whether it's visited (on this specific path), and what conditions lead to it
+
+Let me think about what files this would change:
+
+1. **`engine/types.ts`** — Add `PlayerTreeNode` interface (sceneId, label, children, visited, locked, lockHint)
+2. **`engine/core/SceneManager.ts`** — Add `buildPlayerTree(startScene, visited, stateManager)` method
+3. **`src/components/StoryGallery.vue`** — Replace the flat `sceneListForChapter()` with tree rendering
+4. **`src/components/ChapterRecap.vue`** — May change or be replaced
+
+Actually, the key insight is simpler than I initially thought. The tree projection is just a different way to traverse and display the graph:
+
+```typescript
+interface PlayerTreeNode {
+  sceneId: string
+  label: string
+  visited: boolean
+  locked: boolean
+  lockHint?: string  // e.g., "trust >= 80"
+  children: PlayerTreeNode[]
+}
+
+function buildPlayerTree(
+  sceneId: string,
+  visited: Set<string>,
+  scenes: Record<string, SceneNode>,
+  stateManager: StateManager,
+  depth: number = 0,
+  maxDepth: number = 10
+): PlayerTreeNode {
+  const scene = scenes[sceneId]
+  if (!scene || depth > maxDepth) return { sceneId, label: sceneId, visited: false, locked: true, children: [] }
+  
+  const isVisited = visited.has(sceneId)
+  const children: PlayerTreeNode[] = []
+  
+  // Add choices as children
+  if (scene.choices) {
+    for (const choice of scene.choices) {
+      // Check if this choice is available based on conditions
+      if (choice.conditions && !stateManager.evaluate(choice.conditions)) continue
+      const childNode = buildPlayerTree(choice.targetScene, visited, scenes, stateManager, depth + 1, maxDepth)
+      children.push(childNode)
+    }
+  }
+  
+  // Add nextScene as child
+  if (scene.nextScene) {
+    const childNode = buildPlayerTree(scene.nextScene, visited, scenes, stateManager, depth + 1, maxDepth)
+    children.push(childNode)
+  }
+  
+  // Add QTE outcomes as children
+  if (scene.qte) {
+    children.push(buildPlayerTree(scene.qte.successScene, visited, scenes, stateManager, depth + 1, maxDepth))
+    children.push(buildPlayerTree(scene.qte.failScene, visited, scenes, stateManager, depth + 1, maxDepth))
+  }
+  
+  // Add hotspots as children
+  if (scene.hotspots) {
+    for (const hotspot of scene.hotspots) {
+      if (hotspot.conditions && !stateManager.evaluate(hotspot.conditions)) continue
+      children.push(buildPlayerTree(hotspot.targetScene, visited, scenes, stateManager, depth + 1, maxDepth))
+    }
+  }
+  
+  return {
+    sceneId,
+    label: scene.id,
+    visited: isVisited,
+    locked: false,
+    children
+  }
+}
+```
+
+Wait, this function doesn't need stateManager.evaluate — conditions check against player's current variables, but the tree is supposed to show the full structure including locked paths. The LockInfo would come from comparing the condition requirements with the player's current variable values.
+
+Actually, let me reconsider. The P23 concept is about two things:
+1. The data structure distinction (graph vs tree) — this is clear
+2. The display strategy — showing the tree to the player
+
+The display strategy is what needs to be implemented. The current StoryGallery shows a flat list. The new version would show a hierarchical tree.
+
+Let me think about the minimal set of changes:
+
+1. **`engine/types.ts`** — Add `PlayerTreeNode { sceneId, label, visited, locked, lockHint, children }`  
+2. **`src/components/StoryGallery.vue`** — Replace `sceneListForChapter()` with tree rendering (indented tree view)
+3. That's it — the BFS logic already exists in ChapterRecap, it just needs to output a tree instead of a flat list
+
+Actually, the tree building function doesn't need to be in the engine — it's a pure UI rendering concern. The engine just provides scenes + visited data. The tree projection belongs in the Vue component.
+
+Let me formulate the P23 implementation plan:
+
+### P23 implementation plan
+
+**Objective:** In StoryGallery/ChapterRecap, display the chapter's branch structure as a tree (indented hierarchy) instead of a flat list. Visited nodes shown green, locked nodes shown gray with condition hints.
+
+**Data changes:**
+- `engine/types.ts` — Add `PlayerTreeNode` interface (or keep it in the component)
+
+**Component changes:**
+- `src/components/StoryGallery.vue` — Replace flat `sceneListForChapter()` with recursive tree rendering
+  - `buildPlayerTree(startScene, visitedIds, scenes)` — recursively traverse the graph, building a tree
+  - Render tree nodes with indentation (depth-based)
+  - Visited = green ✅, locked = gray 🔒, normal unvisited = gray ⬜
+  - Condition hints shown on locked nodes
+
+**Verification:**
+- Flat list becomes indented tree
+- Converging nodes appear multiple times (once per path)
+- Condition-locked nodes show lock hints
+
+This is ~150 lines of code change in essentially one file (StoryGallery.vue) plus a type definition.
+
+Now, since I'm in plan mode, I should present this as a clean P23 rewrite.
+
+P23 可以改成可执行的实现计划。核心思路是把 StoryGallery 中的**平铺场景列表**升级为**缩进树形结构**，汇聚节点复制展示。
+
+---
+
+## P23 改造方案
+
+### 改动文件（3 个）
+
+| 文件 | 改动 |
+|------|------|
+| `engine/types.ts` | 新增 `PlayerTreeNode` 接口 |
+| `src/components/StoryGallery.vue` | 用 `buildPlayerTree()` 替代 `sceneListForChapter()`，递归渲染缩进树 |
+| `public/scenes/demo.json` | 无需改动，当前图已有汇聚节点（多个路径到 `desk_detail`） |
+
+### PlayerTreeNode 类型
+
+```typescript
+interface PlayerTreeNode {
+  sceneId: string
+  label: string
+  visited: boolean
+  locked: boolean
+  lockHint?: string
+  children: PlayerTreeNode[]
+}
+```
+
+### 渲染效果（对比）
+
+**当前（平铺列表）：**
+```
+✅ intro
+✅ left_door
+⬜ trust_ending  🔒 trust >= 80
+⬜ alone_ending
+```
+
+**新方案（缩进树）：**
+```
+✅ intro
+  ├ ✅ left_door
+  │   ├ ⬜ trust_ending  🔒 trust >= 80
+  │   └ ⬜ alone_ending
+  ├ ✅ right_door
+  │   ├ ✅ qte_success
+  │   │   └ ✅ continue_ending
+  │   └ ⬜ qte_fail
+  └ ✅ stay
+      └ ⬜ alone_ending    ← 汇聚节点，在两条路径下各出现一次
+```
+
+### 验证清单
+
+- 场景列表改为缩进树形展示
+- 汇聚节点（如 `alone_ending`）在多个父节点下各出现一次
+- visited 绿色 ✅ / 未访问灰色 ⬜ / 条件锁定 🔒 + hint
+- 深度超过 10 层的路径自动截断
+

+
+Done. Let me also move the architecture principle to the "关键架构决策记录" section and remove the duplicate dependencies block.
+
+Actually, the old P23 had the architecture principle and a duplicate dependencies block. The new P23 doesn't have those anymore — so the only thing to clean up is the duplicate dependency block that was at the bottom of old P23. Since I replaced the entire P23 content, that duplicate is gone.
+
+Let me verify the result.
+
+已更新 P23。核心变更：
+
+- 从架构设计文档 → **可执行的实现计划**（2 个文件改动）
+- `buildPlayerTree()` 递归构建缩进树，汇聚节点自动复制
+- 纯 CSS 树连线（`border-left` 竖线 + `::before` 横线）

+
+如果有回环的话，当前会不会无线递归渲染树
+
+---
+
+## Assistant (Plan · DeepSeek V4 Pro · 22.4s)
+
+_Thinking:_
+
+The user is asking about a potential infinite recursion problem with the `buildPlayerTree()` approach in P23. If the scene graph has a loop (A → B → C → A), the recursive tree builder would loop forever.
+
+Let me think about this:
+
+The current StoryGallery uses `collectReachable(startId)` which does BFS with a `visited` Set to prevent infinite loops. This collects all reachable scenes as a flat set.
+
+The new `buildPlayerTree()` approach needs to handle loops too. But since the tree replicates nodes (each "convergence" creates a copy), we can't use a simple `visited` Set — we'd lose the copies.
+
+The solution from the design is in the implementation checklist: **递归终止条件：深度 > 10 自动截断**. This means we have a `maxDepth` parameter that stops recursion after 10 levels, regardless of loops.
+
+But this is a band-aid. The real question is: does `depth > 10` fully prevent infinite recursion? Yes — because the depth counter always increases with each recursive call, and when it reaches the max (10), the function returns without making more children. Even in an infinite loop scenario (A → B → A → B → ...), the tree would render:
+```
+A (depth 1)
+  B (depth 2)
+    A (depth 3)
+      B (depth 4)
+        ...
+          A/B (depth 10) ⊥ 截断
+```
+
+So `maxDepth` is the guard. This is a reasonable approach for a display-focused feature — the user likely won't have game paths deeper than 5-6 scenes anyway.
+
+The implementation also needs a `visited` set per **path** (not globally) to prevent cycles within a single branch. The global `visited` Set wouldn't work because we want copies at convergence points. Instead:
+- Per-recursion-path use a local `pathSet: Set<string>` to detect cycles
+- If a scene ID already appears in the current path → stop recursion (cycle detected)
+- `maxDepth` as the absolute fallback
+
+Actually, a cleaner approach: use `maxDepth` only. It's simpler and covers all cases. No need for path-set tracking.
+
+Let me respond to the user.
+
+当前设计用 `maxDepth = 10` 兜底，确实能防止无限递归——每层递增 depth，到 10 就截断。但这个方案不优雅——正常路径到回环处显示 10 层重复节点，没有意义。
+
+### 更好的方案：路径内去重 + 深度截断
+
+```typescript
+function buildPlayerTree(
+  sceneId: string, 
+  visitedIds: Set<string>, 
+  depth: number,
+  pathSet: Set<string>   // ← 新增：当前路径上已出现的场景 ID
+): PlayerTreeNode | null {
+  if (depth > 10) return null
+  if (pathSet.has(sceneId)) return null  // ← 回环检测，不渲染重复
+
+  pathSet.add(sceneId)
+  // ... 遍历 choices/nextScene/QTE/hotspots 构建 children ...
+  pathSet.delete(sceneId)
+}
+```
+
+**两层保护：**
+
+| 机制 | 作用 |
+|------|------|
+| `pathSet` | 同一路径上遇到重复 ID → 立即返回 `null`（回环精确剪枝） |
+| `maxDepth (10)` | 即使 `pathSet` 漏掉，也不会炸栈 |
+
+**效果：**
+```
+A → B → C → A（回环）
+  → 渲染到 A 第二次出现时，pathSet 已包含 A → 返回 null → 该分支显示为叶子节点
+```
+
+需要我把这个保护机制更新到 ROADMAP P23 吗？

+
+_Thinking:_
+
+Now I'll:
+1. Add `PlayerTreeNode` to types.ts
+2. Replace `sceneListForChapter()` with `buildPlayerTree()` in StoryGallery.vue
+3. Replace the flat recap list template with a recursive tree component
+4. Add CSS for tree lines
+
+The key changes:
+- Add `PlayerTreeNode` interface to types.ts
+- Replace `sceneListForChapter` with `buildPlayerTree` that takes a `pathSet` for cycle detection
+- Replace the template recap section with a recursive tree renderer
+- Add CSS for tree indentation and lines

+_Thinking:_
+
+Wait, my approach of defining TreeNode inline is problematic. Vue SFC doesn't support multiple `<script>` blocks cleanly. Let me take a different approach — create a separate `TreeNode.vue` component that renders itself recursively, or better yet, use a recursive approach within the template without a separate component.
+
+Actually, the cleanest approach is to create a separate `TreeNode.vue` component in the components directory for recursive tree rendering. Or even simpler, I can just inline the TreeNode rendering logic within the StoryGallery template using a `<component :is>` pattern or just a recursive function that returns vnodes.
+
+Actually, the simplest approach that avoids the complexity of recursive Vue components: I can inline the tree rendering directly in the template using a recursive pattern. Vue SFC supports a component referencing itself by its name. But that requires a named component in Options API or a separately declared component.
+
+Let me take the simplest approach: create `src/components/TreeNode.vue` as a standalone recursive component.
+
+My approach is flawed — inline `<script>` blocks in Vue SFC are complex. Let me create a separate `TreeNode.vue` component and keep StoryGallery clean.
