fix(web): tick player time every frame and keep lyrics in sync (#107)

`store.elapsed` is a Pinia getter (a cached Vue computed) that interpolates
with `Date.now()`. Because `Date.now()` is not a reactive dependency, the
computed only re-ran on WebSocket pushes / the 3s server poll, so the bottom
progress bar jumped ~3s at a time and lyric highlighting lagged ~half a line —
even though the consumers read it from a 60fps requestAnimationFrame loop.

Add a pure `interpolateElapsed()` helper and a non-cached `liveElapsed()` store
action. The per-frame consumers now call `liveElapsed()` so the value advances
every frame instead of returning a frozen cache:
- web/src/components/Player.vue  (desktop progress bar, rAF)
- web/src/App.vue                (mobile progress bar, rAF)
- web/src/views/Lyrics.vue       (lyric highlight, 500ms interval)

pause() now freezes at the live value rather than a possibly-stale cached one.
The `elapsed` getter is refactored onto the same helper (behaviour unchanged).

Adds web/src/stores/elapsed.test.ts covering the time-advancing interpolation,
paused freeze, no-anchor, and duration-clamp cases.

 ## 更新升级
 
+> **⚠️ 从使用 `@honeybbq/teamspeak-client 0.1.x` 的旧版本升级时的重要变更**
+>
+> 本项目已将底层 TeamSpeak 协议库升级到 `0.2.x` 并移除了内置的 TS6 兼容层，改用库自带的通用 `clientinit` 协议。这涉及一次**数据库迁移**：
+>
+> **旧的身份（identity）不兼容新的加密握手路径。** `0.1.0` 版本的库在生成 TS 客户端身份时存在 P-256 公钥 DER 编码错误，该 bug 在 `0.1.1` 中由本项目维护者 [ZHANGTIANYAO1](https://github.com/HoneyBBQ/teamspeak-js/pull/5) 修复并合并到上游。`0.1.0` 生成的身份与 `0.2.x` 修复后的握手路径**不兼容**：升级后用旧身份连接会卡在 `received initivexpand2` 直到 15 秒超时。
+>
+> **解决办法**：升级后清空受影响机器人的 `identity` 字段，下次启动时程序会自动生成新身份并持久化。
+>
+> ```bash
+> # 对每个需要迁移的机器人执行（替换 <bot-id> 为实际 UUID）：
+> python -c "import sqlite3; db=sqlite3.connect('data/tsmusicbot.db'); \
+>   db.execute(\"UPDATE bot_instances SET identity=NULL WHERE id='<bot-id>'\"); \
+>   db.commit()"
+>
+> # 或者清空所有机器人的身份：
+> python -c "import sqlite3; db=sqlite3.connect('data/tsmusicbot.db'); \
+>   db.execute('UPDATE bot_instances SET identity=NULL'); db.commit()"
+> ```
+>
+> **影响范围**：
+> - ✅ TS3 服务器 + 旧身份：在多数情况下仍可正常工作（TS3 对 legacy 编码更宽容），可选择不清空
+> - ❌ TS6 服务器 + 旧身份：**必须**清空身份才能连接
+> - ⚠️ 清空身份后，TS 服务器会把机器人识别为**全新的客户端**。之前手动赋予机器人的**服务器组需要用新 UID 重新授予一次**，之后每次重启都会自动保留
+>
+> **如何判断是否需要迁移**：如果你是全新安装，或者你的机器人数据库中 `identity` 字段已经是空的，则**无需任何操作**。完成上述步骤后，按下面对应的系统升级步骤执行即可。
+
+### 从 WebUI 无鉴权版本升级（重要）
+
+本次更新引入了**强制 WebUI 鉴权**。从无鉴权旧版本升级后，**WebUI 必须先创建管理员账号才能使用**。所有 `/api/*` 端点（除少量公共白名单）和 `/ws` 现在都需要登录。
+
+**升级行为**：
+
+- 启动时数据库自动迁移：新增 `users`、`sessions`、`user_audit` 三张表；旧的 `bot_instances`、`play_history` 数据**完全保留**。
+- 第一次打开 WebUI 自动跳转到 `/first-run` 引导创建首位管理员（角色固定为 `admin`）。
+- 之后访问任何页面都会校验登录态，未登录跳转 `/login`。
+
+**会话与 Cookie**：
+
+- 登录态保存 7 天，每次请求滚动续期（活跃用户不会被踢出）。
+- 同一账号最多保持 10 个并发会话（超过自动剔除最旧的）。
+- Cookie 设置为 `HttpOnly; SameSite=Lax`，HTTPS 部署需配合 `trustProxy: true`（详见 [反向代理部署注意事项](#反向代理部署注意事项)）。
+
+**多用户与角色**：
+
+- 角色 `admin`：完整权限（用户管理、审计、机器人、音乐平台、播放控制）。
+- 角色 `member`：除"用户管理"和"操作审计"外的所有功能（适合给团队成员开通播放权）。
+- 在 **设置 → 用户管理**（仅管理员）中添加 / 删除 / 重置密码 / 切换角色。
+- 至少保留一个管理员：系统会阻止删除或降级最后一位管理员。
+
+**游客模式 / Guest mode**：
+
+让访客**无需账号密码**即可进入 WebUI 点歌，同时严格限制其可用能力。该功能**默认关闭**，只有管理员能开启。
+
+- **开启方式**：管理员在 **设置 → 游客模式** 打开「允许游客访问」（仅管理员可见此区块）。开启后登录页会出现 **「以游客身份进入」** 按钮，访客点击即可创建游客会话，无需任何凭据。游客共享同一匿名身份、会话有效期较短（约 1 天）。关闭游客模式（或缩小机器人作用域）后立即生效，所有在线游客会话——包括正在连接的实时 WebSocket——会被立刻断开 / 重新限制。
+- **逐项权限（8 个开关，管理员配置）**：除「添加到队列末尾」外**全部默认关闭**，按需逐项放开。
+
+  | 开关 | 字段 | 默认 |
+  |------|------|------|
+  | 添加到队列末尾 | `addToQueue` | **开** |
+  | 添加到下一首 | `playNext` | 关 |
+  | 立即播放（不清空队列） | `playNow` | 关 |
+  | 跳过当前歌曲 | `skip` | 关 |
+  | 暂停/继续/进度/音量 | `transport` | 关 |
+  | 移除/清空队列 | `removeClear` | 关 |
+  | 切换播放模式 / FM | `playMode` | 关 |
+  | 播放整个歌单/专辑 | `playCollection` | 关 |
+
+- **按机器人授权（游客作用域）**：可选择「全部机器人」或指定一份机器人白名单。作用域之外的机器人对游客**不可见、不可控**。
+- **游客始终被禁止**：查看或修改任何设置、管理机器人、设置音乐平台账号 / 凭据、修改音质、收藏歌单、修改密码、访问用户管理与操作审计，以及读取机器人主人的私人歌单 / 私人 FM / 每日推荐等平台账号数据。这些限制不受上面 8 个开关影响，**永远锁死**。
+- **复现 issue #83 的「下一首 only」需求**：在 **设置 → 游客模式** 中关闭「添加到队列末尾」并打开「添加到下一首」，游客便只能把歌曲加到下一首播放。
+
+**如何重置忘记的管理员密码**：
+
+如果你忘记了管理员密码，可以直接编辑 SQLite 数据库 `data/tsmusicbot.db`：
+
+```bash
+# 方案 1：清空所有用户，重新进入 first-run 流程
+sqlite3 data/tsmusicbot.db "DELETE FROM users; DELETE FROM sessions;"
+# 然后重启机器人，浏览器再次访问会自动进入 /first-run
+
+# 方案 2：把指定用户重置为已知密码（密码 'changeme-now' 的 bcrypt 哈希示例如下）
+# 先用 node 生成哈希：
+node -e "console.log(require('bcryptjs').hashSync('changeme-now', 12))"
+# 把输出贴到 SQL 里：
+sqlite3 data/tsmusicbot.db "UPDATE users SET passwordHash='<paste-hash-here>' WHERE username='你的用户名';"
+```
+
+**反向代理用户特别注意**：如果通过 nginx / Caddy / Cloudflare 暴露 WebUI，**必须**在 `config.json` 中设置 `"trustProxy": true`，否则 Cookie 不会带 `Secure` 标志，且登录限流会把所有用户合并到同一个桶。详见下方 [反向代理部署注意事项](#反向代理部署注意事项)。
+
+**`config.adminGroups`（现已启用）**：用于限制管理类聊天命令（`stop`/`clear`/`remove`/`move`/`vol`/`mode`）只能由指定 TeamSpeak 服务器组的成员运行；为空时不做任何限制（向后兼容）。详见 [TeamSpeak 命令权限](#teamspeak-命令权限管理类命令限制)。`config.adminPassword` 则是旧版预留字段，当前版本未使用，保留以兼容旧 `config.json`，可以放心忽略。

+### TeamSpeak 命令权限（管理类命令限制）
+
+默认情况下，频道里任何人都能运行所有聊天命令。你可以把一组「管理类」命令限制为只有特定 TeamSpeak 服务器组的成员才能运行：
+
+- 受限命令：`stop`、`clear`、`remove`、`move`、`vol`、`mode`
+- 其余命令（点歌、队列、跳过、歌词等）始终对所有人开放
+- **默认不限制**：管理服务器组列表为空时，所有命令对所有人开放（向后兼容）
+
+**配置方式**
+
+- 网页端：设置 → 命令权限，填写允许的服务器组 ID（逗号分隔），保存即时生效。
+- 或编辑 `config.json` 的 `adminGroups`（数字数组），例如 `"adminGroups": [6, 8]`。
+
+填入任意服务器组 ID 后，限制立即开启：只有属于这些组之一的用户才能运行受限命令，其他人会收到「⛔ 需要管理员权限（该命令仅限管理员服务器组）」的提示。
+
+> 提示（fail-closed）：当受限命令来自一个机器人当前看不到其服务器组的发送者（例如不在机器人所在频道的私聊），机器人会尝试查询其分组；若仍无法确定，则拒绝执行。
+
+**如何查看服务器组 ID**
+
+在 TeamSpeak 客户端中打开「权限 → 服务器组」（Permissions → Server Groups）对话框，选中某个组后，其 ID 会显示在标题栏/状态栏；或在服务器组管理界面中查看每个组对应的数字 ID。把需要授权的组 ID 填入上面的设置即可。

+## 可选：YouTube 音源
+
+YouTube 是**可选**的音源，默认**未启用**，需要安装 [yt-dlp](https://github.com/yt-dlp/yt-dlp) 才能使用。启用后可通过聊天命令 `!play -y <关键词>` 或 WebUI 的 YouTube 平台选项搜索/播放 YouTube 视频的音频流。
+
+### 启用方式（任选其一）
+
+**方式一：项目本地 `bin/` 目录（推荐）**
+
+将 `yt-dlp` 可执行文件放到项目根目录下的 `bin/` 文件夹，程序会优先使用此路径。该目录已被 `.gitignore` 忽略，不会影响代码更新。
+
+```bash
+# Windows（PowerShell 或 Git Bash）
+mkdir bin
+curl -L -o bin/yt-dlp.exe https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp.exe
+
+# Linux / macOS
+mkdir -p bin
+curl -L -o bin/yt-dlp https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp
+chmod +x bin/yt-dlp
+```
+
+**方式二：系统级安装（让 `yt-dlp` 在 `PATH` 中可用）**
+
+```bash
+# Windows
+winget install yt-dlp
+
+# macOS
+brew install yt-dlp
+
+# Debian/Ubuntu
+sudo apt install yt-dlp
+
+# 通用（Python 环境下）
+pip install -U yt-dlp
+```
+
+### 验证是否可用
+
+重启机器人程序，在 WebUI 或 `!play -y lofi` 测试搜索。若 `bin/` 和 `PATH` 中都找不到 `yt-dlp`，YouTube 搜索会静默返回空结果（不会影响其他音源），其余功能正常。
+
+### 注意事项
+
+- YouTube 音源通过 `yt-dlp` 本地调用实现，不依赖 API Key，也无需登录
+- 播放的是视频的最佳音频流（`bestaudio[ext=webm]/bestaudio[ext=m4a]/bestaudio`），由 FFmpeg 解码
+- 音质由源视频决定，不受音质设置影响
+- 受 YouTube 风控/地域限制，部分视频可能无法播放
+- `yt-dlp` 更新较频繁，如果播放失败，先尝试升级 `yt-dlp` 到最新版本
+
 ## 配置文件

+配置文件位于 **`data/config.json`**（与数据库、Cookie、日志同在持久化的 `data/` 目录，Docker 部署对应挂载卷），首次运行时自动生成，可手动编辑：

 ```
 
+> **配置文件位置变更**：旧版本把 `config.json` 写在项目根目录（不在 Docker 挂载卷内，导致重启丢失、手动编辑不生效）。现在统一放在 `data/config.json`。升级时若检测到根目录存在旧的 `config.json`，会在首次启动时自动迁移到 `data/` 并保留你的设置，无需手动操作。
+
+> **关于 `adminPassword` 和 `adminGroups`**：`adminGroups` 现已启用，用于限制管理类聊天命令只能由指定 TeamSpeak 服务器组运行（为空 = 不限制），详见 [TeamSpeak 命令权限](#teamspeak-命令权限管理类命令限制)。`adminPassword` 仍为旧版预留字段、当前版本未使用——WebUI 鉴权改为基于数据库的用户账号系统（见 [首次配置](#首次配置)），无需在 `config.json` 中设置密码。
+
+### 反向代理部署注意事项
+
+当 WebUI 部署在反向代理（nginx / Caddy / Cloudflare 等）之后时，请务必在 `config.json` 中设置 `"trustProxy": true`：
+
+- **Cookie Secure 标志**：未启用 `trustProxy` 时，Express 无法从 `X-Forwarded-Proto` 正确判断请求实际是否为 HTTPS，会话 cookie 不会被标记为 `Secure`。
+- **登录限流**：登录限流以 `req.ip` 为键，未启用 `trustProxy` 时所有请求都会被识别为代理本身的 IP，单个攻击者会拖累所有合法用户共用同一个限流桶。
+- **审计日志的客户端 IP**（如果未来添加该字段）也需要 `trustProxy` 才能正确记录。
+
+直接暴露端口（无代理）时无需启用该选项。
+
 ## 常见问题
 
+**Q：支持 TeamSpeak 6 Server 吗？**
+A：支持。本项目内置 TS3/TS6 双协议支持，连接时会自动检测服务器类型。如果自动检测失败（例如 Query 端口被防火墙屏蔽），可以在创建机器人时手动指定 `serverProtocol: "ts6"`。TS6 Server 的 HTTP Query API（端口 10080）也已适配，需要时可配置 `ts6ApiKey`。
+
 **Q：机器人连接了但 TeamSpeak 中听不到音乐？**
 A：确保机器人和你在同一个频道。检查音量（`!vol 75`）。部分 VIP 歌曲需要先登录账号。
 
 **Q：提示"无法获取播放链接"？**
 A：在设置页面扫码登录音乐账号。许多歌曲需要登录后才能播放。
 
+**Q：同名歌曲 `!play` 只能播到最热门的那首，怎么播放指定的版本？**
+A：`!play <歌名>` 默认取最热门的匹配项。要播放同名的另一首，有三种方式：(1) 先 `!search <歌名>` 列出带序号的结果，再 `!play #序号` 选择；(2) `!play id:<歌曲id>` 按 id 精确播放；(3) 直接粘贴歌曲链接，如 `!play https://music.163.com/song?id=442867526`（也支持 QQ / B站 链接）。在 WebUI 中则可直接在搜索结果列表里点选任意同名歌曲。
+
 **Q：如何更换机器人所在频道？**
 A：使用 `!move <频道名>` 命令，或在设置页面创建机器人时指定默认频道。
 
@@ -369,9 +586,36 @@ A：原生模块（opus、sqlite3）需要编译工具，Dockerfile 已包含。
 **Q：B站视频搜索不到结果？**
 A：B站搜索需要 buvid3 匿名 Cookie（程序启动时自动获取）。如果失败，重启程序即可。登录B站账号后搜索效果更好。
 
+**Q：YouTube 平台搜索返回空结果？**
+A：YouTube 是可选音源，需要手动安装 `yt-dlp`。详见 [可选：YouTube 音源](#可选youtube-音源) 章节。快速验证：在项目根目录执行 `bin/yt-dlp --version`（或系统 `yt-dlp --version`），能打印版本号即可。若 yt-dlp 已安装但仍搜索失败，通常是网络/地域问题或 yt-dlp 版本过旧（执行 `yt-dlp -U` 升级）。
+
 **Q：如何更新到新版本？**
 A：`git pull` 拉取最新代码，然后 `npm install && npm run build && npm start` 重新构建启动。Docker 用户执行 `docker-compose up -d --build`。
 
+**Q：忘记管理员密码怎么办？**
+A：直接操作 SQLite 数据库。最简单的办法是清空 `users` 表然后重新进入 first-run 流程：`sqlite3 data/tsmusicbot.db "DELETE FROM users; DELETE FROM sessions;"`，重启后浏览器会自动跳转 `/first-run` 让你重新创建管理员。详细方法见 [从 WebUI 无鉴权版本升级](#从-webui-无鉴权版本升级重要)。
+
+**Q：成员（member）能做什么？不能做什么？**
+A：成员默认可以：管理机器人（启动/停止/创建/编辑）、控制播放（搜索/播放/队列）、登录音乐平台账号、修改自己的密码。成员**始终不能**：管理其他用户、查看操作审计日志、降级或删除管理员。此外管理员可在 **设置 → 用户管理** 为每个成员单独**收紧权限**：勾选允许的能力（播放控制 / 队列 / 机器人管理 / 平台登录 / 音质）以及可操作的机器人白名单——未授权的能力会返回 403，未授权的机器人对该成员不可见也不可控。管理员不受任何限制。
+
+**Q：收藏的歌单存在哪里？其他用户能看到吗？**
+A：收藏按用户存储在本地 SQLite 数据库（`favorite_playlists` 表），仅本人可见，登录后跨设备同步。在首页、搜索结果或歌单页点击收藏图标即可增删。
+
+**Q：什么是"专属链接"？怎么用？**
+A：通过 `/bot/<机器人ID>` 打开 WebUI 会把界面锁定到该机器人（顶部显示"专属模式"，刷新后保持），适合把单台机器人的控制页分享给特定用户。点击"退出"可返回多机器人视图。注意：专属链接只是 UI 层的锁定，真正的访问控制由成员权限（机器人白名单）在后端强制。
+
+**Q：机器人播放时突然自动暂停了？**
+A：这是"频道无人时自动暂停"功能：当机器人所在频道没有其他人时会自动暂停，有人加入后自动恢复，避免空播。该功能**默认关闭**，仅在你于 **设置 → 行为设置** 开启后生效；如需停用，在同一页面关闭即可。（占用检测依赖 TeamSpeak 的 `clientlist` 命令，部分服务器在频道有其他人时可能查询失败——此时机器人会按"占用情况未知"处理，不会误暂停。）
+
+**Q：如何把某个用户从成员升级为管理员？**
+A：管理员登录后进入 **设置 → 用户管理**，点击对应用户的"提升管理员"按钮即可。降级同理（"降为成员"按钮）。系统会阻止降级最后一位管理员。
+
+**Q：登录之后多久会自动退出？**
+A：登录态有效期 7 天，活跃使用会滚动续期（每次受保护请求都会刷新过期时间）。同一账号最多保持 10 个并发会话（多设备登录时超过的会自动剔除最旧的会话）。
+
+**Q：部署到公网后如何防止暴力登录？**
+A：本项目内置 `/login` 限流（每 IP 每分钟 5 次），但生产部署建议同时在反向代理（nginx `limit_req` / Caddy 等）层加一层限流，并启用 HTTPS。反向代理部署务必设置 `"trustProxy": true`（详见 [反向代理部署注意事项](#反向代理部署注意事项)）。

+
+> 完整历史请查看 [git log](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/commits/main) 或 [Releases](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/releases)。这里只列出重要变更和面向用户的破坏性改动。
+
+### 最新版本
+
+**功能增强：细粒度权限 / 本地收藏 / 本地音频上传 / 专属链接 / 自动暂停 / QQ 雷达 FM**
+
+- **细粒度账号权限**（叠加在 admin / member 之上）：管理员可为每个成员勾选 5 项能力（`player.control` / `player.queue` / `bot.manage` / `platform.auth` / `quality`）和按机器人授权白名单；所有变更路由由后端 `requirePermission` / `requireBotAccess` 中间件逐请求强制校验，未授权返回 403，未授权的机器人对成员不可见（列表过滤，无 403-vs-404 枚举泄漏）。已有成员经一次性迁移获得全部能力，新成员默认基础能力。
+- **本地收藏歌单**：按用户存储的收藏（`favorite_playlists` 表 + `/api/favorites`），首页 / 搜索 / 歌单页一键收藏，跨设备同步。
+- **本地音频上传播放**：搜索页支持拖拽 / 选择本地音频上传（保存到 `data/local-audio`），上传后可像普通歌曲一样播放、下一首播放或加入队列；设置 → 行为设置 中新增「本地音频播放」开关，关闭后拒绝新的本地上传和本地歌曲播放请求。播放结束或停止 / 清空 / 替换队列时会从服务端删除已接收文件并更新索引。
+- **专属链接（单机器人锁定）**：`/bot/<id>` 打开时锁定到单台机器人，`?bot=<id>` 随刷新保持；与权限白名单组合，机器人下拉只显示"作用域 ∩ 可控"的机器人。
+- **频道无人时自动暂停**：机器人所在频道清空时暂停、有人加入时恢复（区分用户手动暂停，不会误恢复）；可在 设置 → 行为设置 开关（默认关闭）。占用检测在 `clientlist` 查询失败时按"未知"处理而非"无人"，避免有人在听时被误暂停。
+- **QQ 音乐雷达 / 私人 FM**：`!fm -q` 或 WebUI 启动 QQ 雷达推荐流（失败回退"猜你喜欢"），FM 自动续播现支持任意平台。
+
+**Bug 修复**
+
+- **#86 config.json 未在首次运行生成**：配置文件改放到持久化的 `data/config.json`（旧版写在项目根目录，不在 Docker 卷内，导致重启丢失、手动编辑不生效）；升级时自动把根目录旧配置迁移到 `data/` 并保留你的设置。
+- **#89 B站长音频约 16 分钟被暂停且无法继续**：ffmpeg 增加 `-reconnect_at_eof`（B站 CDN 会在 token/会话到期时提前关闭连接造成 EOF），并新增"远离结尾的卡死看门狗"——彻底卡死的流会自动推进到下一首而不是永久静音。
+- **#84 音量曲线不顺滑**：0–100 改为连续单调曲线 `0.2x + 0.8x^8`（消除 80–99 的"死区"与 100 处的突跳，满响度仍保留在 100）。
+
+**WebUI 鉴权与权限系统**
+
+- **首次运行强制创建管理员账号**：浏览器打开 WebUI 自动跳转 `/first-run`；之后所有 `/api/*`（除少量公共白名单：`/api/health`、`/api/config/public-url`、`/api/session/*`）和 `/ws` 都需要登录。详见 [更新升级 → 从 WebUI 无鉴权版本升级](#从-webui-无鉴权版本升级重要)。
+- **两种角色：admin / member**。`member` 可以管理机器人、控制播放、登录音乐平台账号、修改自己密码，但不能管理其他用户或查看审计日志。`admin` 拥有全部权限。
+- **用户管理 UI**：管理员在 设置 → 用户管理 可以增删用户、切换角色、重置密码。系统强制保留至少一位管理员。
+- **操作审计日志**：管理员在 设置 → 操作审计 可以查看用户管理相关事件（创建、删除、密码重置、角色变更、首位管理员创建、自助修改密码）。
+- **自助修改密码**：所有用户都可在 设置 → 账户 修改自己密码。
+- **会话存储**：服务端 SQLite 表 `sessions`，存储 sha256(token)；浏览器只持有原始 token cookie。7 天 TTL，每小时滚动续期。同账号最多 10 个并发会话（超出剔除最旧）。
+- **登录限流**：每 IP 每分钟 5 次 `/login` + 3 次 `/setup`，命中返回 429 + `Retry-After`。
+- **CSRF & 安全头**：所有 mutating 请求强制 `Origin`/`Referer` 同源；响应携带 `X-Frame-Options: DENY` 和 `Content-Security-Policy: frame-ancestors 'none'`（防点击劫持）。
+- **配置变更**：反向代理部署务必 `"trustProxy": true`（详见 [反向代理部署注意事项](#反向代理部署注意事项)）。`config.adminGroups` 现已启用，用于限制管理类聊天命令只能由指定 TeamSpeak 服务器组运行（为空 = 不限制，详见 [TeamSpeak 命令权限](#teamspeak-命令权限管理类命令限制)）；`config.adminPassword` 仍为旧版预留字段，保留以兼容旧 `config.json`，当前未使用。
+
+### v0.x — Bot Profile 自动更新与协议层升级
+
+**机器人形象自动更新（Bot Profile）**
+
+- **播放时自动更新 TS 形象**：头像（专辑封面缩略图）、昵称（`♪ 歌名 - 歌手 - 原昵称`）、描述（歌曲信息）、Away 状态、频道描述、"正在播放"频道消息，全部随歌曲切换自动更新。
+- **停止播放时恢复默认**：头像清除、昵称恢复、Away 显示"等待播放"、描述和频道描述清空。
+- **权限安全**：每项功能独立检测权限，权限不足时自动禁用该功能（不影响其他功能和播放），重连后重试。
+- **独立可配置**：6 项功能可通过 REST API（`GET/PUT /api/player/:botId/profile`）独立开关，配置持久化到数据库。
+- **竞争条件防护**：generation 计数器防止快速切歌时旧头像覆盖新头像；UTF-8 字节长度截断中文昵称；文件传输操作带超时保护。
+- **TS3 适配**：描述通过 `clientedit`（非 `clientupdate`）设置，需要 `b_client_modify_description` 权限；昵称和 Away 通过合并的单条 `clientupdate` 避免命令队列超时。
+
+**新命令 & FM 修复**
+
+- **新增 `!artist <歌手名>` 命令**：搜索指定歌手的歌曲并循环播放，支持 `-q`（QQ 音乐）/ `-b`（B站）/ `-y`（YouTube）平台切换。一次加载最多 50 首，自动按歌手名过滤并设为 Loop 模式。
+- **歌单模糊搜索**：`!playlist` 现在支持歌单名称模糊搜索（如 `!playlist 华语经典`），自动匹配公开歌单 + 个人歌单（网易云 + QQ）。纯数字 ID 和 URL 解析保持兼容。
+- **修复 `!fm` 播放中断**：私人 FM 几首歌后静音的 bug 已修复。新增自动续播机制（队列低位自动拉取新歌），播放器健康帧追踪防止临时 URL 失败导致永久静音。
+- **QQ 音乐个人歌单**：QQ Music provider 新增 `getUserPlaylists` 支持，登录后可通过 `!playlist -q <名称>` 模糊搜索个人歌单。
+
+**协议层 & 稳定性**
+
+- **升级 `@honeybbq/teamspeak-client` 到 `0.2.1`**，移除内置 TS6 兼容层（`ts6-compat.ts`），改用库自带的通用 `clientinit` 协议（`3.?.? [Build: 5680278000]`），TS3/TS6 单一代码路径。
+  - ⚠️ **破坏性**：`0.1.0` 生成的旧身份与新握手路径不兼容，升级时需要迁移。详见 [更新升级](#更新升级) 章节顶部的警告。
+- **修复 `startBot` 与 `stopBot` 之间的竞态**：mid-handshake 被替换的 BotInstance 不再泄漏 TS 会话，`disconnect()` 被 `connect()` 的 await 插队时不再错误地把 `connected` 翻回 `true`。
+- **修复播放条自动刷新 bug**：BotManager 现在在创建新 BotInstance 时 emit `botInstance` 事件，WebSocket 监听器会立即重新挂接到新实例，播放状态变化无需手动刷新页面。
+- **`connect()` 增加 15 秒超时**：握手卡住时会清理掉挂起的实例并返回 500，不再无限阻塞 HTTP 请求和 UI。
+- **识别持久化修复**：`startBot` 现在会从数据库读取 `identity` 传给新 BotInstance，服务器组在机器人重启后能保留。
+
+**HTTP API 加固**
+
+- 新增输入校验，拒绝无效值并返回 **400**（之前会返回 200 包装 usage-text 字符串）：
+  - `/volume`：非数字、`NaN`/`Infinity`、超出 `[0,100]`
+  - `/mode`：不在 `{seq, loop, random, rloop}` 中的值
+  - `/seek`：`NaN`/`Infinity`、负数、字符串
+  - `/play-at`：索引越界（**先**校验再停止当前播放，避免误杀正在播的歌）
+- **修复 YouTube 平台路由**：`/play`、`/add`、`/playlist`、`/play-by-id`、`/add-by-id`、`/play-playlist` 现在都正确处理 `platform=youtube`（之前会静默回退到网易云）。
+- **修复 `/auth/status?platform=youtube` 数据泄漏**：之前会回退到网易云并返回网易云用户的昵称 + 头像 URL，现在正确路由到 YouTube provider 并报告 `yt-dlp` 的实际可用状态。
+- **`/auth/cookie` 拒绝 `platform=youtube`**，防止意外覆盖网易云 cookie。
+
+**连接状态一致性**
+
+- 断开连接时，音频命令（`play`/`add`/`next`/`prev`/`playlist`/`album`/`fm`）返回 **400 "Bot is not connected to TeamSpeak"**；配置类命令（`volume`/`mode`/`clear`/`stop`/`queue`/`now`/`lyrics`）仍可正常工作，保持 UI 可用。
+- `resolveAndPlay` 在网络请求（URL 解析）前后都会检查 `this.connected`，防止在解析期间被 `stop()` 中断后仍然启动 ffmpeg。
+- `tsClient` 的 `disconnected` 事件处理器现在总是清理播放器状态，不再因为 `connect()` 从未完成而遗留 `playing=true` 的僵尸状态。
+
+**功能改进**
+
+- **YouTube 音源（可选）**：新增基于 `yt-dlp` 的 YouTube provider，通过 `!play -y <关键词>` 或 WebUI 平台选项使用。未安装 `yt-dlp` 时静默降级、返回空结果，不影响其他音源。详见 [可选：YouTube 音源](#可选youtube-音源)。
+- **Bot Selector UI**：
+  - 始终可见（不再只有 ≥2 个机器人时才显示）
+  - 尺寸放大（更大的按钮、字体、状态图标）
+  - 每行增加 **电源按键**（一键启动/停止对应机器人，带禁用态与播放状态高亮）
+  - 每行增加 **链接按钮**（复制机器人专属 URL）
+  - 新路由 `/bot/:id`，打开后自动切换到对应机器人
+- **服务器密码登录**：`serverPassword` 字段已加入数据库与 Settings UI，支持加入需要密码的 TS 服务器。
+- **`!add` 一键开播**：在连接状态下向空队列 `!add` 歌曲时自动开始播放（之前只会入队，需要再 `!play` 或 `!next`）。
+- **WebSocket 新增 `botRemoved` 事件**：删除机器人后 UI 会立即从列表中移除（之前需要手动刷新页面）。
+
+**内部修复**
+
+- **`PlayQueue.remove()` 当前歌曲移除 bug**：移除正在播放的歌曲时，`next()` 不再跳过紧跟其后的那首歌。
+- **投票跳过**：需要的票数现在至少为 1（避免 `needed=0` 时单人"全票通过"的边界情况）；投票计数会在每首新歌开始时自动清零，不再跨歌曲泄漏。
+- 多处输入边界修复：`seek` 防止 `NaN` 毒化 `seekOffset` 导致 `getElapsed()` 永久返回 `NaN`；`play-at` 越界时不再误杀当前播放。
+
+### 历史重要变更
+
+更早的变更请查阅 git log。主要里程碑：
+
+- **初始 TS3/TS6 双协议支持**：自动协议检测（TS3 port 10011 vs TS6 port 10080）、TS6 HTTP Query 客户端、数据库持久化 `serverProtocol` / `ts6ApiKey`。
+- **多机器人架构**：支持同一进程中运行多个机器人实例，独立队列、进度、音量；WebUI 一键切换。
+- **网易云 / QQ 音乐 / 哔哩哔哩**：三平台原生音源，QR 码登录，Cookie 持久化。
+- **Docker & systemd 部署**：一键部署脚本，数据卷持久化，自动重启支持。

+# FM Bug Fix + Artist Loop + Playlist Fuzzy Search — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix FM audio dropout bug, add `!artist` command for artist-based loop playback, and support playlist name fuzzy search in `!playlist`.
+
+**Architecture:** All changes stay within existing files. The FM fix adds auto-refill logic and a success-tracking mechanism in the player. Playlist search reuses the existing `provider.search()` API that already returns playlists. The `!artist` command is a new command method following the same pattern as `cmdPlay`/`cmdFm`.
+
+**Tech Stack:** TypeScript, Node.js, ffmpeg-static, @honeybbq/teamspeak-client
+
+---
+
+## File Map
+
+| File | Change | Purpose |
+|------|--------|---------|
+| `src/bot/instance.ts` | Modify | Add `isFmMode`, `refillFm()`, fix `cmdFm()`, modify `cmdPlaylist()`, add `cmdArtist()`, modify `playNext()` to trigger FM refill |
+| `src/bot/commands.ts` | Modify | Register `artist` in PUBLIC_COMMANDS, update help text |
+| `src/audio/player.ts` | Modify | Track healthy frame count, reset `consecutiveFailures` after sustained successful playback |
+
+---
+
+### Task 1: Fix FM — Track healthy playback in AudioPlayer
+
+**Files:**
+- Modify: `src/audio/player.ts:62-82` (add field)
+- Modify: `src/audio/player.ts:243-261` (sendNextFrame — track healthy frames)
+
+- [ ] **Step 1: Add healthy frame counter field**
+
+In `src/audio/player.ts`, after the `consecutiveFailures` field (line ~80), add:
+
+```typescript
+private healthyFrames = 0;
+private static readonly HEALTHY_FRAME_RESET = 50; // ~1 second of audio
+```
+
+- [ ] **Step 2: Track healthy frames and reset failures in sendNextFrame**
+
+In `src/audio/player.ts`, in the `sendNextFrame()` method, after line 257 (`this.framesPlayed++;`), add:
+
+```typescript
+this.healthyFrames++;
+if (this.healthyFrames >= AudioPlayer.HEALTHY_FRAME_RESET) {
+  this.consecutiveFailures = 0;
+  this.healthyFrames = 0;
+}
+```
+
+- [ ] **Step 3: Reset healthyFrames in play() and stop()**
+
+In `play()`, after `this.framesPlayed = 0;` (line ~95), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+In `stop()`, after `this.framesPlayed = 0;` (line ~181), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/audio/player.ts
+git commit -m "fix(player): reset consecutiveFailures after sustained healthy playback"
+```
+
+---
+
+### Task 2: Fix FM — Add auto-refill logic in BotInstance
+
+**Files:**
+- Modify: `src/bot/instance.ts:62-66` (add fields)
+- Modify: `src/bot/instance.ts:557-573` (cmdFm)
+- Modify: `src/bot/instance.ts:642-673` (playNext — add refill trigger)
+
+- [ ] **Step 1: Add isFmMode field**
+
+In `src/bot/instance.ts`, after `private profileManager: BotProfileManager;` (line ~66), add:
+
+```typescript
+private isFmMode = false;
+```
+
+- [ ] **Step 2: Add refillFm method**
+
+In `src/bot/instance.ts`, before the `cmdVote` method (after `cmdFm`'s closing brace), add:
+
+```typescript
+private async refillFm(): Promise<void> {
+  if (!this.isFmMode || !this.neteaseProvider.getPersonalFm) return;
+  try {
+    const songs = await this.neteaseProvider.getPersonalFm();
+    if (songs.length === 0) return;
+    for (const song of songs) {
+      this.queue.add({ ...song, platform: "netease" });
+    }
+    this.logger.debug({ count: songs.length }, "FM queue refilled");
+  } catch (err) {
+    this.logger.error({ err }, "Failed to refill FM queue");
+  }
+}
+```
+
+- [ ] **Step 3: Modify cmdFm to set isFmMode and use RandomLoop**
+
+Replace the existing `cmdFm` method (lines 557-573) with:
+
+```typescript
+private async cmdFm(): Promise<string> {
+  if (!this.neteaseProvider.getPersonalFm) {
+    return "Personal FM is only available for NetEase Cloud Music";
+  }
+  const songs = await this.neteaseProvider.getPersonalFm();
+  if (songs.length === 0)
+    return "No FM songs available (need to login first)";
+
+  this.queue.clear();
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: "netease" });
+  }
+  this.queue.setMode(PlayMode.RandomLoop);
+  this.isFmMode = true;
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Personal FM started: ${first?.name ?? "unknown"} - ${first?.artist ?? ""}`;
+}
+```
+
+- [ ] **Step 4: Modify playNext to trigger FM refill and check isFmMode**
+
+In `playNext()`, replace the `else` branch (lines 665-668) that handles `queue.next() === null`:
+
+```typescript
+} else {
+  // FM mode: try to refill instead of stopping
+  if (this.isFmMode) {
+    await this.refillFm();
+    const refillNext = this.queue.next();
+    if (refillNext) {
+      const started = await this.resolveAndPlay(refillNext);
+      if (!started) {
+        this.player.stop();
+        this.profileManager.onSongChange(null).catch(() => {});
+      }
+      this.emit("stateChange");
+    } else {
+      this.player.stop();
+      this.profileManager.onSongChange(null).catch(() => {});
+    }
+  } else {
+    this.player.stop();
+    this.profileManager.onSongChange(null).catch(() => {});
+  }
+}
+```
+
+Also add a proactive refill after successful advance. At the end of the `if (next)` block, after `this.emit("stateChange");` is handled outside the if/else, add this right after `resolveAndPlay` succeeds (inside the `if (next)` block, after the retry loop):
+
+After the `if (!started)` block and before the closing `}` of `if (next)`, insert:
+
+```typescript
+// Proactive FM refill when running low
+if (this.isFmMode && this.queue.size() - (this.queue.getCurrentIndex()) <= 3) {
+  this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+}
+```
+
+Wait — `this.emit("stateChange")` is outside the `if (next)` block. Let me re-read the original code structure...
+
+The original `playNext()` structure is:
+```
+if (next) {
+    let started = await resolveAndPlay(next)
+    if (!started) { retry loop... }
+    if (!started) { stop }
+} else {
+    stop
+}
+emit("stateChange")
+```
+
+So I need to add the proactive refill inside the `if (next)` block, right after `resolveAndPlay` succeeds. Let me write this more carefully:
+
+```typescript
+private async playNext(): Promise<void> {
+    if (this.isAdvancing || !this.connected) return;
+    this.isAdvancing = true;
+    try {
+      this.voteSkipUsers.clear();
+      const next = this.queue.next();
+      if (next) {
+        let started = await this.resolveAndPlay(next);
+        if (!started) {
+          for (let i = 0; i < 3 && this.connected; i++) {
+            const retry = this.queue.next();
+            if (!retry) break;
+            if (await this.resolveAndPlay(retry)) {
+              started = true;
+              break;
+            }
+          }
+        }
+        if (!started) {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        } else if (this.isFmMode && this.queue.size() - this.queue.getCurrentIndex() <= 3) {
+          // Proactive refill: when queue is running low, fetch more FM songs
+          this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+        }
+      } else {
+        // Queue exhausted — in FM mode, refill instead of stopping
+        if (this.isFmMode) {
+          await this.refillFm();
+          const refillNext = this.queue.next();
+          if (refillNext) {
+            await this.resolveAndPlay(refillNext);
+          } else {
+            this.player.stop();
+            this.profileManager.onSongChange(null).catch(() => {});
+          }
+        } else {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        }
+      }
+      this.emit("stateChange");
+    } finally {
+      this.isAdvancing = false;
+    }
+  }
+```
+
+OK this is getting complex. Let me simplify the plan — I'll structure it more clearly.
+
+Also I need to clear `isFmMode` when user issues stop/clear or manually plays something else.
+
+- [ ] **Step 5: Clear isFmMode in stop/clear/play commands**
+
+In `cmdStop()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdClear()` (same line), add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlay()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlaylist()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdAlbum()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/instance.ts
+git commit -m "fix: FM auto-refill to prevent audio dropout after initial batch"
+```
+
+---
+
+### Task 3: Playlist Fuzzy Search
+
+**Files:**
+- Modify: `src/bot/instance.ts:524-539` (cmdPlaylist)
+
+- [ ] **Step 1: Modify cmdPlaylist to support name search**
+
+Replace the `cmdPlaylist` method (lines 524-539) with:
+
+```typescript
+private async cmdPlaylist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !playlist <playlist name or ID>";
+  const provider = this.getProvider(cmd.flags);
+
+  // Determine if input is a numeric ID or a name search
+  const id = this.extractId(cmd.args);
+  const isNumericId = /^\d+$/.test(cmd.args.trim());
+
+  let playlistId: string;
+
+  if (isNumericId || id !== cmd.args) {
+    // Input is a numeric ID or URL containing an ID — use existing logic
+    playlistId = id;
+  } else {
+    // Name-based search
+    const result = await provider.search(cmd.args);
+    let playlists = result.playlists ?? [];
+
+    // Also search user's personal playlists if logged in
+    if (provider.getUserPlaylists) {
+      try {
+        const userPlaylists = await provider.getUserPlaylists();
+        const query = cmd.args.toLowerCase();
+        const matched = userPlaylists.filter(
+          p => p.name.toLowerCase().includes(query)
+        );
+        // Merge: public results first (API-ranked), then user matches
+        playlists = [...playlists, ...matched];
+      } catch {
+        // User playlists unavailable — continue with public results
+      }
+    }
+
+    if (playlists.length === 0)
+      return `No playlists found for: ${cmd.args}`;
+    playlistId = playlists[0].id;
+  }
+
+  const songs = await provider.getPlaylistSongs(playlistId);
+  if (songs.length === 0) return "Playlist is empty or not found";
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Loaded ${songs.length} songs. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 2: Update help text to reflect new usage**
+
+In `cmdHelp()` (line ~633), change the playlist line from:
+
+```
+`${p}playlist <id> — Load playlist`
+```
+
+to:
+
+```
+`${p}playlist <name or id> — Load playlist by name or ID`
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/bot/instance.ts
+git commit -m "feat: support playlist name fuzzy search in !playlist command"
+```
+
+---
+
+### Task 4: Artist Loop Command
+
+**Files:**
+- Modify: `src/bot/commands.ts:8-11` (PUBLIC_COMMANDS)
+- Modify: `src/bot/commands.ts:248-260` (AUDIO_COMMANDS in instance.ts — actually in instance.ts)
+- Modify: `src/bot/instance.ts:244-314` (executeCommand switch + add cmdArtist)
+
+Wait, AUDIO_COMMANDS is in instance.ts executeCommand. Let me check...
+
+Actually looking back at instance.ts, the AUDIO_COMMANDS set is local to executeCommand. I don't need to add artist there since it will be handled in the switch.
+
+- [ ] **Step 1: Register `artist` in PUBLIC_COMMANDS**
+
+In `src/bot/commands.ts`, line 9, add `"artist"` to the PUBLIC_COMMANDS set:
+
+```typescript
+export const PUBLIC_COMMANDS = new Set([
+  "play", "add", "queue", "list", "now", "lyrics", "vote", "help",
+  "playlist", "album", "fm", "prev", "next", "skip", "pause", "resume",
+  "artist",
+]);
+```
+
+- [ ] **Step 2: Add `artist` to the AUDIO_COMMANDS set in executeCommand**
+
+In `src/bot/instance.ts`, in the `executeCommand` method, add `"artist"` to the AUDIO_COMMANDS set (line ~253):
+
+```typescript
+const AUDIO_COMMANDS = new Set([
+  "play", "add", "next", "skip", "prev", "playlist", "album", "fm",
+  "artist",
+]);
+```
+
+- [ ] **Step 3: Add `artist` case to the switch in executeCommand**
+
+In `src/bot/instance.ts`, after the `case "fm":` block (line ~300), add:
+
+```typescript
+case "artist":
+  return this.cmdArtist(cmd);
+```
+
+- [ ] **Step 4: Implement cmdArtist method**
+
+Add the `cmdArtist` method in `src/bot/instance.ts`, after `cmdFm()`:
+
+```typescript
+private async cmdArtist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !artist <artist name>";
+  const provider = this.getProvider(cmd.flags);
+  const result = await provider.search(cmd.args, 50);
+  if (result.songs.length === 0)
+    return `No results found for artist: ${cmd.args}`;
+
+  const query = cmd.args.toLowerCase();
+  let filtered = result.songs.filter(
+    s => s.artist.toLowerCase().includes(query)
+  );
+
+  // Fallback to unfiltered results if filtering drops everything
+  if (filtered.length === 0) {
+    filtered = result.songs.slice(0, 20);
+  }
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of filtered) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  this.queue.setMode(PlayMode.Loop);
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Artist mode: ${cmd.args} — ${filtered.length} songs loaded. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 5: Update help text**
+
+In `cmdHelp()`, add the artist help line after the fm line:
+
+```
+`${p}artist <name> — Play songs by artist (loop)`
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/commands.ts src/bot/instance.ts
+git commit -m "feat: add !artist command for artist-based loop playback"
+```
+
+---
+
+### Task 5: Type-check and verify
+
+**Files:**
+- All modified files
+
+- [ ] **Step 1: Run type check**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && npm run typecheck
+```
+
+Expected: No errors.
+
+- [ ] **Step 2: Verify command parsing**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && node --loader ts-node/esm -e "
+const { parseCommand } = await import('./src/bot/commands.ts');
+console.log(parseCommand('!artist 周杰伦', '!'));
+console.log(parseCommand('!artist 周杰伦 -q', '!'));
+console.log(parseCommand('!playlist 华语经典', '!'));
+console.log(parseCommand('!playlist 123456', '!'));
+"
+```
+
+Expected: All parse correctly; `artist` with args "周杰伦", `playlist` with args "华语经典" and "123456".
+
+- [ ] **Step 3: Commit any fixes from type check**
+
+```bash
+git add -A && git commit -m "chore: type fixes from final verification"
+```
+(Only if there were issues)
+
+---
+
+### Self-Review Checklist
+
+1. **Spec coverage:**
+   - FM bug fix → Tasks 1, 2 (healthy frame tracking + auto-refill)
+   - Playlist fuzzy search → Task 3
+   - Artist loop → Task 4
+   - Verification → Task 5
+
+2. **No placeholders** — all steps have exact code.
+
+3. **Type consistency:**
+   - `isFmMode: boolean` — used in cmdFm, cmdStop, cmdClear, cmdPlay, cmdPlaylist, cmdAlbum, playNext, refillFm ✓
+   - `refillFm(): Promise<void>` — called from cmdFm (indirectly via playNext trigger), playNext ✓
+   - `healthyFrames: number`, `HEALTHY_FRAME_RESET: 50` — used in play(), stop(), sendNextFrame() ✓

+# Music Source Tabs Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add NetEase / QQ source-switcher tabs to Home (推荐歌单 / 每日推荐 / 我的歌单) and Library (我的歌单), with per-section persistence and graceful degradation when only one source is logged in.
+
+**Architecture:** A single shared `<SourceTabs>` Vue component handles the tab UI and self-hides when fewer than 2 sources are available. The Pinia store splits the affected fields into `{ netease, qq }` objects, fetches from both platforms in `fetchHomeData()` based on `authStatus`, and consumers select with a reactive `activeSource` ref persisted to localStorage.
+
+**Tech Stack:** Vue 3 (Composition API + `<script setup>`), Pinia, TypeScript, SCSS (CSS variables from `web/src/styles/variables.scss`).
+
+**Spec:** `docs/superpowers/specs/2026-05-06-music-source-tabs-design.md`
+
+---
+
+## File Structure
+
+**New:**
+- `web/src/components/SourceTabs.vue` — shared tab UI (presentational, no store deps)
+
+**Modified:**
+- `web/src/stores/player.ts` — state shape change + `authStatus` + `fetchHomeData` rewrite
+- `web/src/views/Home.vue` — 3 sections wired to SourceTabs
+- `web/src/views/Library.vue` — 1 section wired; remove dead `liked` block
+
+**Unchanged:**
+- Backend (already supports `?platform=qq`)
+- All other web pages
+
+---
+
+## Task 1: Build the SourceTabs component
+
+**Files:**
+- Create: `web/src/components/SourceTabs.vue`
+
+This task is fully independent of store changes — the component is presentational, takes typed props, and emits an update event. It can land and be committed alone (build will pass; component is just unused until later tasks).
+
+- [ ] **Step 1.1: Create the component file**
+
+Write `web/src/components/SourceTabs.vue`:
+
+```vue
+<template>
+  <div v-if="sources.length >= 2" class="source-tabs">
+    <button
+      v-for="src in sources"
+      :key="src"
+      type="button"
+      class="source-tab"
+      :class="{ active: src === modelValue }"
+      @click="$emit('update:modelValue', src)"
+    >
+      {{ LABELS[src] }}
+    </button>
+  </div>
+</template>
+
+<script setup lang="ts">
+type Source = 'netease' | 'qq';
+
+const LABELS: Record<Source, string> = {
+  netease: '网易云',
+  qq: 'QQ',
+};
+
+defineProps<{
+  modelValue: Source;
+  sources: Source[];
+}>();
+
+defineEmits<{
+  'update:modelValue': [value: Source];
+}>();
+</script>
+
+<style lang="scss" scoped>
+.source-tabs {
+  display: inline-flex;
+  gap: 4px;
+  margin-left: 12px;
+  align-items: center;
+}
+
+.source-tab {
+  padding: 4px 10px;
+  min-height: 28px;
+  font-size: var(--fs-sm);
+  font-weight: var(--fw-medium);
+  color: var(--text-secondary);
+  background: transparent;
+  border: none;
+  border-radius: var(--radius-sm);
+  cursor: pointer;
+  transition: color var(--transition-fast), background var(--transition-fast);
+
+  &:hover {
+    color: var(--text-primary);
+    background: var(--hover-bg);
+  }
+
+  &.active {
+    color: var(--color-primary);
+    background: var(--color-primary-12);
+    font-weight: var(--fw-semi);
+  }
+}
+
+@media (max-width: 768px) {
+  .source-tabs {
+    margin-left: 8px;
+    gap: 2px;
+  }
+
+  .source-tab {
+    padding: 6px 10px;
+    min-height: 36px; // larger touch target on mobile
+    font-size: var(--fs-xs);
+  }
+}
+</style>
+```
+
+Why these choices:
+- `v-if="sources.length >= 2"` — auto-hide when only one source available; parent doesn't need wrapper logic
+- Min-height 28px desktop / 36px mobile — comfortable touch on phones
+- `--color-primary-12` (12% primary tint) — matches existing active-state pattern in the codebase
+- No `--brand-netease/qq` in active state — keeps tab visually consistent regardless of which platform; brand colors are reserved for SongCard platform badges where they identify content origin
+
+- [ ] **Step 1.2: Verify it imports cleanly via type check**
+
+Run from project root:
+
+```
+npx tsc --noEmit
+```
+

+## Task 2: Refactor the store (state + fetchHomeData)
+
+**Files:**
+- Modify: `web/src/stores/player.ts`
+
+This task changes types, which will break Home.vue and Library.vue at compile time. **Do not run tsc/build between Task 2 and Task 4** — they are migrated in a single coherent commit. After Task 4, type-check confirms the whole change.
+
+- [ ] **Step 2.1: Add the `Source` type alias and update state shape**
+
+In `web/src/stores/player.ts`, locate the `state: () => ({ ... })` block (around line 47-63).
+
+**Find:**
+
+```ts
+    // Home page cache
+    recommendPlaylists: [] as PlaylistItem[],
+    dailySongs: [] as Song[],
+    userPlaylists: [] as PlaylistItem[],
+    bilibiliPopular: [] as Song[],
+    lastFetchTime: 0,
+```
+
+**Replace with:**
+
+```ts
+    // Home page cache, split by source
+    recommendPlaylists: { netease: [] as PlaylistItem[], qq: [] as PlaylistItem[] },
+    dailySongs:         { netease: [] as Song[],         qq: [] as Song[] },
+    userPlaylists:      { netease: [] as PlaylistItem[], qq: [] as PlaylistItem[] },
+    bilibiliPopular: [] as Song[],
+    authStatus: { netease: false, qq: false },
+    lastFetchTime: 0,
+```
+
+Also add this exported type at the top of the file, right after the existing `Song` interface (around line 12):
+
+```ts
+export type Source = 'netease' | 'qq';
+```
+
+- [ ] **Step 2.2: Rewrite `fetchHomeData()`**
+
+In the same file, find the `fetchHomeData` action (around line 352-378).
+
+**Replace the entire action body with:**
+
+```ts
+    async fetchHomeData() {
+      if (this.lastFetchTime > 0 && Date.now() - this.lastFetchTime < HOME_CACHE_TTL) {
+        return;
+      }
+
+      // 1. Fetch auth status for both platforms first.
+      const [neAuthRes, qqAuthRes] = await Promise.allSettled([
+        axios.get('/api/auth/status', { params: { platform: 'netease' } }),
+        axios.get('/api/auth/status', { params: { platform: 'qq' } }),
+      ]);
+      this.authStatus.netease =
+        neAuthRes.status === 'fulfilled' && !!neAuthRes.value.data?.loggedIn;
+      this.authStatus.qq =
+        qqAuthRes.status === 'fulfilled' && !!qqAuthRes.value.data?.loggedIn;
+
+      // 2. NetEase data: recommend playlists work anonymously; daily/user
+      // playlists need login but Promise.allSettled isolates failures.
+      const neteasePromises = [
+        axios.get('/api/music/recommend/playlists', { params: { platform: 'netease' } }),
+        axios.get('/api/music/recommend/songs',     { params: { platform: 'netease' } }),
+        axios.get('/api/music/user/playlists',      { params: { platform: 'netease' } }),
+      ];
+
+      // 3. QQ data: only fetch when QQ is logged in. When not logged in,
+      // resolve to empty payloads so the same indexed handling works.
+      const emptyPlaylists = { data: { playlists: [] } };
+      const emptySongs     = { data: { songs: [] } };
+      const qqPromises = this.authStatus.qq
+        ? [
+            axios.get('/api/music/recommend/playlists', { params: { platform: 'qq' } }),

+          ];
+
+      const biliPromise = axios.get('/api/music/bilibili/popular?limit=12');
+
+      const results = await Promise.allSettled([
+        ...neteasePromises,
+        ...qqPromises,
+        biliPromise,
+      ]);
+
+      const [neRecPL, neDaily, neUserPL, qqRecPL, qqDaily, qqUserPL, bili] = results;
+
+      if (neRecPL.status === 'fulfilled') {
+        this.recommendPlaylists.netease = neRecPL.value.data.playlists ?? [];
+      }
+      if (neDaily.status === 'fulfilled') {
+        this.dailySongs.netease = neDaily.value.data.songs ?? [];
+      }
+      if (neUserPL.status === 'fulfilled') {
+        this.userPlaylists.netease = neUserPL.value.data.playlists ?? [];

+      }
+      if (bili.status === 'fulfilled') {
+        this.bilibiliPopular = bili.value.data.songs ?? [];
+      }
+
+      this.lastFetchTime = Date.now();
+    },
+```
+
+**Do NOT type-check yet** — Home/Library still reference the old shape. They'll be migrated in Tasks 3 and 4.

+
+## Task 3: Migrate Home.vue to multi-source tabs
+
+**Files:**
+- Modify: `web/src/views/Home.vue`
+
+- [ ] **Step 3.1: Add a localStorage helper module**
+
+Create `web/src/stores/sourceTabs.ts`:
+
+```ts
+import type { Source } from './player.js';
+
+const STORAGE_KEY = 'source-tabs';
+
+export type TabKey =
+  | 'home.recommend'
+  | 'home.daily'
+  | 'home.user'
+  | 'library.user';
+
+function readAll(): Partial<Record<TabKey, Source>> {
+  try {
+    const raw = localStorage.getItem(STORAGE_KEY);
+    if (!raw) return {};
+    const parsed = JSON.parse(raw);
+    return typeof parsed === 'object' && parsed !== null ? parsed : {};
+  } catch {
+    return {};
+  }
+}
+
+export function loadTabSource(key: TabKey, fallback: Source = 'netease'): Source {
+  const all = readAll();
+  const v = all[key];
+  return v === 'netease' || v === 'qq' ? v : fallback;
+}
+
+export function saveTabSource(key: TabKey, value: Source): void {
+  try {
+    const all = readAll();
+    all[key] = value;
+    localStorage.setItem(STORAGE_KEY, JSON.stringify(all));
+  } catch {
+    // localStorage may be unavailable (private browsing); silently no-op
+  }
+}
+```
+
+This is a separate file rather than inline so Library can reuse it without duplication.
+
+- [ ] **Step 3.2: Update Home.vue template**
+
+Replace the three `<section>` blocks (推荐歌单 / 每日推荐 / 我的歌单) and the `<script setup>` block.
+
+**Find** the entire `<template>` 推荐歌单 section (currently around lines 53-67):

+
+Note: The 我的歌单 template uses `userSource` (not `userSourceSafe`) on the `<SourceTabs>` v-model so the user's click maps directly to the persisted ref. The grid below the tabs uses `currentUserPlaylists` which derives from `userSourceSafe`, so even if `userSource` points at an unavailable platform momentarily, the grid still renders something sensible. Same pattern for 推荐歌单 / 每日推荐.

+  </div>
+</template>
+```
+
+Changes from the previous version:
+- "我的歌单" section: same data binding pattern as Home (`userAvailable`, `currentUserPlaylists`, `<SourceTabs>`)
+- "我的收藏" section: removed entirely (the `/api/music/user/liked` endpoint never existed)
+- Empty state condition: replaced `liked.length === 0` with `userAvailable.length === 0`
+
+- [ ] **Step 4.2: Replace the script block**
+
+**Find** the `<script setup lang="ts">` block (currently lines 66-105) and **replace with:**
+
+```ts
+<script setup lang="ts">
+import { ref, computed, watch, onMounted } from 'vue';
+import { Icon } from '@iconify/vue';
+import axios from 'axios';
+import { usePlayerStore, type Song, type Source } from '../stores/player.js';
+import { loadTabSource, saveTabSource } from '../stores/sourceTabs.js';
+import CoverArt from '../components/CoverArt.vue';
+import SongCard from '../components/SongCard.vue';
+import SourceTabs from '../components/SourceTabs.vue';
+
+const store = usePlayerStore();
+
+const history = ref<Song[]>([]);
+const historyLoading = ref(true);
+
+const userAvailable = computed<Source[]>(() => {
+  const s: Source[] = [];
+  if (store.authStatus.netease) s.push('netease');
+  if (store.authStatus.qq) s.push('qq');
+  return s;
+});
+
+const userSource = ref<Source>(loadTabSource('library.user'));
+watch(userSource, (v) => saveTabSource('library.user', v));
+
+const userSourceSafe = computed<Source>(() =>
+  userAvailable.value.includes(userSource.value)
+    ? userSource.value
+    : userAvailable.value[0] ?? 'netease'
+);
+
+const currentUserPlaylists = computed(() => store.userPlaylists[userSourceSafe.value] ?? []);
+
+onMounted(async () => {
+  if (!store.activeBotId) {
+    await store.fetchBots();
+  }
+
+  store.fetchHomeData();
+
+  if (store.activeBotId) {
+    try {
+      const res = await axios.get(`/api/player/${store.activeBotId}/history`);
+      history.value = res.data.history ?? [];
+    } catch {
+      // API may not be ready
+    }
+  }
+
+  historyLoading.value = false;
+});
+</script>
+```
+
+Changes:
+- Removed `liked` ref and the `/api/music/user/liked` axios call
+- Added auth-driven `userAvailable`, persisted `userSource`, and `currentUserPlaylists` computed
+- Imports `Source` type and `SourceTabs` component
+
+- [ ] **Step 4.3: Style — `.section-title` already supports inline children**
+
+The existing `.section-title` style (Library.vue and Home.vue both) already uses `display: flex; align-items: center; gap: 8px;`. SourceTabs uses `display: inline-flex` with its own `margin-left`, so it sits inline with the title and count. **No style changes are required in either Home.vue or Library.vue.**
+
+---
+
+## Task 5: Verify the build and types
+
+- [ ] **Step 5.1: Run TypeScript backend type check**
+
+```
+npx tsc --noEmit
+```
+
+Expected: exit code 0, no output. (No backend files were touched.)
+
+- [ ] **Step 5.2: Run web type check + production build**
+
+```
+npm run build:web
+```
+
+Expected: build completes with `✓ built in N.NNs` and no TypeScript errors. The script runs `vue-tsc --noEmit && vite build`, so failures here mean a type or template error in our changes.
+
+- [ ] **Step 5.3: Run the existing test suite to confirm no regression**
+
+```
+npm test
+```
+
+Expected: same baseline as before this feature (`Test Files 2 failed | 26 passed (28)`, `Tests 2 failed | 161 passed (163)`). The 2 pre-existing failures are in `dist/` and `.claude/worktrees/` and are unrelated to our changes — they should remain at exactly 2.
+
+If any **source-tree** test fails (anything not in `dist/` or `.claude/worktrees/`), stop and investigate.
+
+---
+
+## Task 6: Manual smoke test on the dev server
+
+This task verifies behavior the type system can't catch.
+
+- [ ] **Step 6.1: Start the dev server**
+
+```
+npm run dev
+```
+
+Wait for `Web server started` and `WebUI: http://localhost:3000` log lines.
+
+- [ ] **Step 6.2: Test scenario A — only NetEase logged in**
+
+Open http://localhost:3000 in a browser. Confirm:
+
+- 推荐歌单 section displays NetEase playlists, **no tab bar visible** (single source, SourceTabs auto-hidden)
+- 每日推荐 section: visible only if NetEase login provides daily songs; **no tab bar**
+- 我的歌单 section: visible if NetEase has user playlists; **no tab bar**
+- Navigate to `/library`: 我的歌单 section: same — no tab bar, NetEase playlists shown
+
+Open DevTools → Application → Local Storage → `localhost:3000` → `source-tabs` should be absent or `{}` (no clicks happened).
+
+- [ ] **Step 6.3: Test scenario B — both NetEase and QQ logged in**
+
+If QQ is not logged in, log in via Settings → QQ Music → 扫码登录.
+
+Hard reload the browser (Cmd/Ctrl+Shift+R) to bypass the 5-min `lastFetchTime` cache.
+
+Confirm:
+
+- 推荐歌单: tab bar shows `[网易云] [QQ]`, NetEase active by default
+- Click `QQ` — playlist grid switches to QQ data, no flicker (data already in store)
+- Click `网易云` — back to NetEase
+- Same for 每日推荐 and 我的歌单
+- Navigate to `/library`, confirm 我的歌单 has its own tab bar with independent state
+- Reload the page — Home tabs and Library tab persist their last-selected source independently
+
+Check `localStorage['source-tabs']`: should contain JSON with up to 4 keys (`home.recommend`, `home.daily`, `home.user`, `library.user`).
+
+- [ ] **Step 6.4: Test scenario C — fallback when persisted source becomes unavailable**
+
+While logged into both:
+1. On Home, switch 推荐歌单 to `QQ`. Confirm `localStorage['source-tabs']['home.recommend'] === 'qq'`.
+2. Go to Settings → log out of QQ.
+3. Hard-reload Home.
+
+Confirm:
+- 推荐歌单 tab bar disappears (only NetEase available)
+- Grid shows NetEase playlists (graceful fallback via `recommendSourceSafe`)
+- `localStorage['source-tabs']['home.recommend']` is **still `'qq'`** (preference preserved)
+4. Log back into QQ → reload → 推荐歌单 grid is QQ again (preference restored)
+
+- [ ] **Step 6.5: Test mobile layout**
+
+Open DevTools → Toggle device toolbar → set width to 375px (iPhone SE).
+
+Confirm on Home and Library:
+- Section title + tab bar fit on the same line without overflow
+- Tab buttons are at least 36px tall (use Inspect → check computed `min-height`)
+- Tabs are tappable (clicking still switches sources)
+
+- [ ] **Step 6.6: Stop the dev server**
+
+Kill the `npm run dev` process.
+
+---
+
+## Task 7: Final commit
+
+- [ ] **Step 7.1: Stage and commit Task 2 + 3 + 4 changes**
+
+```
+git add web/src/stores/player.ts web/src/stores/sourceTabs.ts web/src/views/Home.vue web/src/views/Library.vue
+git status
+```
+
+Expected `git status` output: 4 modified/new files staged, working tree otherwise clean (apart from pre-existing `.claude/worktrees/` and `test-ts6-version.cjs` untracked).
+
+```
+git commit -m "feat(web): per-platform source tabs on Home and Library
+
+Recommend playlists, daily songs, and user playlists on Home now show
+a [网易云][QQ] tab when both platforms are logged in. Library 我的歌单
+gets the same tab. Selection persists per-section in localStorage and
+falls back gracefully when the persisted source becomes unavailable
+(e.g., user logged out). Removes dead 我的收藏 block from Library that
+referenced a non-existent /api/music/user/liked endpoint.

+# Album Search & Playback Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Surface albums in search results and allow playing the whole album from the web UI. Currently `SearchResult.albums` is always `[]` and Search.vue only renders songs.
+
+**Architecture:** Extend `search()` in netease + qq providers to populate `albums`. Aggregate them in `/search/all`. Add a new "专辑" (and "歌单") section to Search.vue. Reuse `Playlist.vue` as the album detail page by branching on `route.meta.kind` between `/playlist/:id` and `/album/:id` endpoints. The existing `getAlbumSongs(id)` and `/api/music/album/:id` endpoint already work.
+
+**Tech Stack:** Node 20 + TS, Express 5, Vue 3 + Vue Router 4, axios. No new deps.
+
+---
+
+## Spec Reference
+
+`docs/superpowers/specs/2026-05-07-custom-avatar-and-album-search-design.md` — section "专辑搜索".
+
+## File Structure
+
+| File | Action | Responsibility |
+|---|---|---|
+| `src/music/provider.ts` | Read-only | Verify `Album` and `SearchResult.albums` shape (no change expected) |
+| `src/music/netease.ts` | Modify | `search()` adds a third parallel call (`type=10`) and maps albums |
+| `src/music/qq.ts` | Modify | `search()` adds `req_album` section and maps albums |
+| `src/music/netease.test.ts` | Modify | New tests for albums in search response |
+| `src/music/qq.test.ts` | Modify (or create if absent) | Tests for albums in qq search |
+| `src/web/api/music.ts` | Modify | `/search/all` returns `{songs, albums, playlists}` |
+| `web/src/views/Search.vue` | Modify | Render albums + playlists sections |
+| `web/src/views/Playlist.vue` | Modify | Branch endpoint by `route.meta.kind === 'album'` |
+| `web/src/router/index.ts` | Modify | Add `/album/:id` route reusing Playlist component, set `meta.kind = 'album'` |
+
+## Conventions
+
+- TDD throughout. Each task: failing test → implement → verify → commit.
+- Mock HTTP via existing fixtures pattern (look at `src/music/netease.test.ts` for setup).
+- Keep all platform-specific quirks inside the provider class — no leaking into Search.vue logic.
+
+---
+
+### Task 1: netease.ts — fetch albums in search
+
+**Files:**
+- Modify: `src/music/netease.ts`
+- Modify: `src/music/netease.test.ts`
+
+- [ ] **Step 1: Read the existing test setup so we mock the same way**
+
+```bash
+grep -n 'cloudsearch\|MockAdapter\|axios.create\|mock\|nock\|fixture' src/music/netease.test.ts | head -20
+```
+
+- [ ] **Step 2: Write the failing test**
+
+Append to `src/music/netease.test.ts` inside the existing `describe`:
+
+```ts
+  it("populates SearchResult.albums from cloudsearch type=10", async () => {
+    // Adjust the fixture/mock helper to your existing test pattern.
+    // The test should: arrange a mock that returns a non-empty albums array
+    // for type=10, run search(), assert result.albums has the expected shape.
+    mockApi.onGet("/cloudsearch", { params: expect.objectContaining({ type: 10 }) }).reply(200, {
+      result: {
+        albums: [
+          { id: 42, name: "Album A", picUrl: "https://x/p.jpg", artists: [{ name: "Artist X" }] },
+        ],
+      },
+    });
+    mockApi.onGet("/cloudsearch", { params: expect.objectContaining({ type: 1 }) }).reply(200, { result: { songs: [] } });
+    mockApi.onGet("/cloudsearch", { params: expect.objectContaining({ type: 1000 }) }).reply(200, { result: { playlists: [] } });
+
+    const provider = makeProvider();
+    const r = await provider.search("foo", 5);
+    expect(r.albums).toEqual([
+      { id: "42", name: "Album A", artist: "Artist X", coverUrl: "https://x/p.jpg", platform: "netease" },
+    ]);
+  });
+```
+
+If the existing tests use a different mock library (e.g. `msw` or manual axios stubbing), translate the fixture above to match. Do not introduce new test deps.
+
+- [ ] **Step 3: Run test to verify it fails**
+
+Run: `npx vitest run src/music/netease.test.ts`
+Expected: FAIL — `result.albums` is `[]`
+
+- [ ] **Step 4: Implement the change**
+
+In `src/music/netease.ts` `search()` (~line 93), change the `Promise.all` from 2 to 3 calls:
+
+```ts
+const [songRes, playlistRes, albumRes] = await Promise.all([
+  this.api.get("/cloudsearch", { params: { keywords: query, type: 1, limit, ...this.cookieParams } }),
+  this.api.get("/cloudsearch", { params: { keywords: query, type: 1000, limit: 5, ...this.cookieParams } }),
+  this.api.get("/cloudsearch", { params: { keywords: query, type: 10, limit: 5, ...this.cookieParams } }),
+]);
+```
+
+After the existing `playlists: Playlist[] = ...` mapping, add:
+
+```ts
+const albums: Album[] = (albumRes.data?.result?.albums ?? []).map((a: any) => ({
+  id: String(a.id),
+  name: a.name ?? "",
+  artist: (a.artists ?? []).map((x: any) => x.name).join(" / "),
+  coverUrl: a.picUrl ?? "",
+  platform: "netease",
+}));
+```
+
+Update the `return { songs, playlists, albums: [] }` to `return { songs, playlists, albums }`.
+
+(Make sure `Album` is imported from `./provider.js`; if not yet imported, add it to the existing import.)
+
+- [ ] **Step 5: Run test to verify it passes**
+
+Run: `npx vitest run src/music/netease.test.ts`
+Expected: PASS
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/music/netease.ts src/music/netease.test.ts
+git commit -m "feat(netease): include albums in search results"
+```
+
+---
+
+### Task 2: qq.ts — fetch albums in search
+
+**Files:**
+- Modify: `src/music/qq.ts`
+- Modify or Create: `src/music/qq.test.ts`
+
+- [ ] **Step 1: Verify whether qq.test.ts exists**
+
+```bash
+ls src/music/qq.test.ts
+```
+
+If absent, create a minimal one mirroring `netease.test.ts` style: instantiate provider, mock the `qqDirectApi` axios instance, assert `r.albums.length > 0` after a `search()` call.
+
+- [ ] **Step 2: Write the failing test**
+
+Add to `src/music/qq.test.ts`:
+
+```ts
+it("populates SearchResult.albums from a parallel album search request", async () => {
+  // Mock returns an album list under req_album.data.body.album.list
+  mockApi.onGet("/cgi-bin/musicu.fcg").reply((cfg) => {
+    const data = JSON.parse(cfg.params?.data ?? "{}");
+    if (data.req_album) {
+      return [200, { req_album: { data: { body: { album: { list: [
+        { albumMID: "abc", albumName: "Aero", singerName: "S", albumPic: "https://x/p.jpg" },
+      ] } } } } }];
+    }
+    if (data.req_0) {
+      return [200, { req_0: { data: { body: { song: { list: [] } } } } }];
+    }
+    return [200, {}];
+  });
+
+  const provider = makeProvider();
+  const r = await provider.search("foo", 5);
+  expect(r.albums).toEqual([
+    { id: "abc", name: "Aero", artist: "S", coverUrl: expect.stringContaining("https://"), platform: "qq" },
+  ]);
+});
+```
+
+Verify the actual QQ API response shape against a real call before finalizing the field names — `albumMID` vs `mid`, `albumPic` vs `pic`, etc. If unsure, log a real response once and freeze the shape in the fixture.
+
+- [ ] **Step 3: Run test to verify it fails**
+
+Run: `npx vitest run src/music/qq.test.ts`
+Expected: FAIL — `r.albums` is `[]`
+
+- [ ] **Step 4: Implement the change**
+
+In `src/music/qq.ts` `search()` (~line 63), change `reqData` to include both `req_0` (songs) and `req_album` (albums):
+
+```ts
+const reqData = JSON.stringify({
+  req_0: {
+    module: "music.search.SearchCgiService",
+    method: "DoSearchForQQMusicDesktop",
+    param: { searchid: "1", query, num_per_page: Math.min(limit, 50), search_type: 0 },
+  },
+  req_album: {
+    module: "music.search.SearchCgiService",
+    method: "DoSearchForQQMusicDesktop",
+    param: { searchid: "1", query, num_per_page: 5, search_type: 8 },
+  },
+});
+```
+
+After the existing `songs` mapping, add:
+
+```ts
+const albumList: any[] = res.data?.req_album?.data?.body?.album?.list ?? [];
+const albums: Album[] = albumList.map((a: any) => ({
+  id: String(a.albumMID ?? a.mid ?? a.albumID ?? ""),
+  name: a.albumName ?? a.title ?? "",
+  artist: a.singerName ?? (a.singer ?? []).map((s: any) => s.name).join(" / "),
+  coverUrl: a.albumMID
+    ? `https://y.gtimg.cn/music/photo_new/T002R300x300M000${a.albumMID}.jpg`
+    : (a.albumPic ?? ""),
+  platform: "qq",
+}));
+```
+
+Change `return { songs, playlists: [], albums: [] }` to `return { songs, playlists: [], albums }`.
+
+- [ ] **Step 5: Run test to verify it passes**
+
+Run: `npx vitest run src/music/qq.test.ts`
+Expected: PASS
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/music/qq.ts src/music/qq.test.ts
+git commit -m "feat(qq): include albums in search results"
+```
+
+---
+
+### Task 3: /search/all — aggregate albums + playlists
+
+**Files:**
+- Modify: `src/web/api/music.ts`
+
+- [ ] **Step 1: Look at the current aggregation**
+
+In `src/web/api/music.ts` near line 40 the `/search/all` handler builds only `songs`. Extend it.
+
+- [ ] **Step 2: Write a failing integration test (if test infra allows)**
+
+If there's already a test file for music.ts, add a test that mocks the providers and asserts `res.body.albums.length > 0`. If not, skip and rely on Task 1+2 unit coverage + manual verification in Task 4.
+
+- [ ] **Step 3: Aggregate albums + playlists**
+
+Replace the existing `songs = ...` block + `res.json({ songs })` at lines ~54–62 with:
+
+```ts
+const songs = [
+  ...(neteaseResult.status === "fulfilled" ? neteaseResult.value.songs : []),
+  ...(qqResult.status === "fulfilled" ? qqResult.value.songs : []),
+  ...(bilibiliResult.status === "fulfilled" ? bilibiliResult.value.songs : []),
+];
+const albums = [
+  ...(neteaseResult.status === "fulfilled" ? neteaseResult.value.albums : []),
+  ...(qqResult.status === "fulfilled" ? qqResult.value.albums : []),
+];
+const playlists = [
+  ...(neteaseResult.status === "fulfilled" ? neteaseResult.value.playlists : []),
+  ...(qqResult.status === "fulfilled" ? qqResult.value.playlists : []),
+];
+
+res.json({ songs, albums, playlists });
+```
+
+(Bilibili intentionally skipped for albums/playlists — no album concept; playlists likewise minor.)
+
+- [ ] **Step 4: Verify by curl**
+
+Build + run, then:
+
+```bash
+curl -s 'http://localhost:3000/api/music/search/all?q=Beyond' \
+  | python3 -c 'import json,sys;d=json.load(sys.stdin);print({k: len(v) for k, v in d.items()})'
+```
+
+Expected: `{'songs': N>0, 'albums': N>0, 'playlists': N>=0}`
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/web/api/music.ts
+git commit -m "feat(api): /search/all returns albums and playlists"
+```
+
+---
+
+### Task 4: Album route reusing Playlist.vue
+
+**Files:**
+- Modify: `web/src/router/index.ts`
+- Modify: `web/src/views/Playlist.vue`
+
+- [ ] **Step 1: Look at the current router config and Playlist load logic**
+
+```bash
+grep -n "path:\|component:\|meta" web/src/router/index.ts
+grep -n "loadPlaylist\|/api/music/playlist\|onMounted" web/src/views/Playlist.vue
+```
+
+- [ ] **Step 2: Add /album/:id route**
+
+In `web/src/router/index.ts`, find the `/playlist/:id` route entry. Right after it, add:
+
+```ts
+  {
+    path: '/album/:id',
+    component: () => import('../views/Playlist.vue'),
+    meta: { kind: 'album' },
+  },
+```
+
+(If `/playlist/:id` is `meta:`-less, also add `meta: { kind: 'playlist' }` to it for symmetry.)
+
+- [ ] **Step 3: Branch the endpoint inside Playlist.vue**
+
+Find the load function (probably `onMounted(async () => { axios.get('/api/music/playlist/' + id, ...) })`). Refactor:
+
+```ts
+const route = useRoute();
+const kind = (route.meta.kind as string) ?? 'playlist'; // 'playlist' | 'album'
+const endpoint = kind === 'album' ? '/api/music/album/' : '/api/music/playlist/';
+// ... use `${endpoint}${route.params.id}` ...
+```
+
+For the hero metadata, the playlist endpoint returns `{songs}` only (no top-level cover/title) — verify what the Album endpoint currently returns. If both only return `{songs}`, the existing Playlist.vue must already derive the cover from somewhere (probably the first song's coverUrl, or an additional `/api/music/playlist/:id/detail` call). Keep the existing pattern; if a separate detail call is needed for albums, fetch the metadata from `/api/music/song/<firstSong.id>` to get the album name + cover, OR add a thin `/api/music/album/:id/detail` endpoint that returns `{ name, coverUrl, description }`.
+
+**Decision:** if Playlist.vue currently uses ONLY `/api/music/playlist/:id` and derives metadata from songs, do the same for albums (no new endpoint). If it calls a separate detail endpoint, add a matching `/api/music/album/:id/detail` returning `{ name, coverUrl }` from the first song's `album` and `coverUrl` fields.
+
+- [ ] **Step 4: Verify in browser**
+
+Run `cd web && npm run dev`. Visit `/album/<some-netease-album-id>` (pick one from a search). Expect: hero header + song list + play-all button — same UX as a playlist page.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add web/src/router/index.ts web/src/views/Playlist.vue
+git commit -m "feat(web): /album/:id route reusing Playlist view"
+```
+
+---
+
+### Task 5: Search.vue — render albums + playlists sections
+
+**Files:**
+- Modify: `web/src/views/Search.vue`
+
+- [ ] **Step 1: Read current Search.vue**
+
+```bash
+sed -n '1,120p' web/src/views/Search.vue
+```
+
+Identify: the `results.value = res.data.songs` line and the `<div v-else-if="results.length > 0">` block.
+
+- [ ] **Step 2: Refactor to three result lists**
+
+Replace the script:
+
+```ts
+import type { Song } from '../stores/player.js';
+
+interface Album { id: string; name: string; artist: string; coverUrl: string; platform: string; }
+interface Playlist { id: string; name: string; coverUrl: string; songCount?: number; platform: string; }
+
+const songs = ref<Song[]>([]);
+const albums = ref<Album[]>([]);
+const playlists = ref<Playlist[]>([]);
+const loading = ref(false);
+const searched = ref(false);
+
+async function doSearch() {
+  if (!query.value.trim()) return;
+  loading.value = true;
+  searched.value = true;
+  try {
+    const res = await axios.get('/api/music/search/all', { params: { q: query.value } });
+    songs.value = res.data.songs ?? [];
+    albums.value = res.data.albums ?? [];
+    playlists.value = res.data.playlists ?? [];
+  } catch {
+    songs.value = []; albums.value = []; playlists.value = [];
+  } finally {
+    loading.value = false;
+  }
+}
+```
+

+- Search.vue renders three sections: 专辑 / 歌单 / 单曲
+- /album/:id route reuses Playlist.vue with meta.kind='album'
+- bilibili / youtube intentionally still return albums:[] (no album API)
+
+## Test plan
+- [x] vitest covers netease + qq search returning non-empty albums
+- [x] curl /search/all?q=周杰伦 returns {songs, albums, playlists}
+- [x] Manual: search → click album card → /album/:id → play all

+
+## Self-Review Checklist
+
+- [x] Spec coverage: backend album search → Tasks 1+2; aggregator → Task 3; album detail route → Task 4; UI sections → Task 5
+- [x] No "TBD"/placeholder text — every step shows the actual diff or command
+- [x] Type names consistent: `Album` (capital A), `albums` (lowercase plural), `SearchResult.albums`
+- [x] Bilibili/YouTube explicitly out of scope per spec — confirmed in Task 3 by skipping them in albums aggregation
+- [x] Routes use `meta.kind` — same key referenced in Playlist.vue (Task 4) and `/album/:id` registration (Task 4 Step 2)

+# Custom Bot Avatar Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let users upload a fixed avatar per bot. When `avatarEnabled=true`, the avatar follows the song cover during playback and reverts to the custom avatar (instead of clearing) on stop. When `avatarEnabled=false` and a custom avatar exists, the bot always shows the custom avatar.
+
+**Architecture:** New SQLite column stores a relative file path; bytes live on disk under `data/avatars/<botId>.<ext>` (mirrors `data/cookies/`). `BotProfileManager` gains a `customAvatar` Buffer; the existing `clearAvatar()` becomes "restore custom or clear"; `onConnect()` immediately applies the custom avatar when sync is off. Three new REST endpoints (GET/PUT/DELETE) under `/api/bot/:id/avatar` accept base64 JSON (avoids adding multer; bump `express.json()` limit).
+
+**Tech Stack:** Node 20 + TS + Express 5, better-sqlite3, Vue 3 + axios. No new runtime deps.

+### Task 1: DB migration + getter/setter for custom avatar path
+
+**Files:**
+- Modify: `src/data/database.ts`
+- Modify: `src/data/database.test.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Add to `src/data/database.test.ts` after the existing tests (find the closing `});` of the last test case in the `describe` block, insert before it):
+
+```ts
+  it("persists and clears customAvatarPath on a bot instance", () => {
+    const inst = {
+      id: "bot-1",
+      name: "B",
+      serverAddress: "x",
+      serverPort: 9987,
+      nickname: "n",
+      defaultChannel: "",
+      channelPassword: "",
+      autoStart: false,
+      serverProtocol: "",
+      ts6ApiKey: "",
+      serverPassword: "",
+    };
+    botDb.saveBotInstance(inst);
+    expect(botDb.getCustomAvatarPath("bot-1")).toBeNull();
+    botDb.setCustomAvatarPath("bot-1", "avatars/bot-1.png");
+    expect(botDb.getCustomAvatarPath("bot-1")).toBe("avatars/bot-1.png");
+    botDb.setCustomAvatarPath("bot-1", null);
+    expect(botDb.getCustomAvatarPath("bot-1")).toBeNull();
+  });
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npx vitest run src/data/database.test.ts`
+Expected: FAIL — `botDb.getCustomAvatarPath is not a function`
+
+- [ ] **Step 3: Add the column to migration + interface + statements**
+
+In `src/data/database.ts`:
+
+1. Find `BotDatabase` interface (~line 54), add two methods before `close()`:
+
+```ts
+  getCustomAvatarPath(botId: string): string | null;
+  setCustomAvatarPath(botId: string, path: string | null): void;
+```
+
+2. Find `migrateSchema()` (~line 66). After the `for (const col of profileCols)` loop, append:
+
+```ts
+  if (!names.includes("custom_avatar_path")) {
+    db.exec("ALTER TABLE bot_instances ADD COLUMN custom_avatar_path TEXT");
+  }
+```
+
+3. In `createDatabase()` after the existing `prepare(...)` calls (~line 180), add:
+
+```ts
+  const selectCustomAvatar = db.prepare(
+    `SELECT custom_avatar_path FROM bot_instances WHERE id = ?`,
+  );
+  const updateCustomAvatar = db.prepare(
+    `UPDATE bot_instances SET custom_avatar_path = ? WHERE id = ?`,
+  );
+```
+
+4. Inside the returned object, add (before `close()`):
+
+```ts
+    getCustomAvatarPath(botId) {
+      const row = selectCustomAvatar.get(botId) as { custom_avatar_path: string | null } | undefined;
+      return row?.custom_avatar_path ?? null;
+    },
+
+    setCustomAvatarPath(botId, path) {
+      updateCustomAvatar.run(path, botId);
+    },
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `npx vitest run src/data/database.test.ts`
+Expected: PASS — all tests including the new one
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/data/database.ts src/data/database.test.ts
+git commit -m "feat(db): custom_avatar_path column + accessors"

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npx vitest run src/bot/profile.test.ts`
+Expected: FAIL — `pm.setCustomAvatar is not a function` and/or `onConnect` not exported
+
+- [ ] **Step 3: Look at the existing profile.ts to understand `onConnect` shape**
+
+Run: `grep -n 'onConnect\|public async\|public ' src/bot/profile.ts | head -10`
+
+`onConnect` likely already exists; if not, locate where reconnect resets state. Add or extend it.
+
+- [ ] **Step 4: Implement `customAvatar`, `setCustomAvatar`, `applyIdleAvatar`; modify `clearAvatar` and `onConnect`**
+
+In `src/bot/profile.ts`:
+
+1. Inside the class, add fields next to `defaultNickname` (around line 27):
+
+```ts
+  private customAvatar: Buffer | null = null;
+```
+
+2. After the `constructor`, add:
+
+```ts
+  /** Set/clear the persistent idle avatar. Pass null to remove. */
+  setCustomAvatar(buffer: Buffer | null): void {
+    this.customAvatar = buffer;
+  }
+```
+
+3. Find `clearAvatar()` (~line 173). Change the body so that if `this.customAvatar` is set, we upload it instead of clearing the flag. Replace the existing method with:
+
+```ts
+  private async clearAvatar(gen: number): Promise<void> {
+    if (this.customAvatar && this.customAvatar.length > 0) {
+      await this.applyIdleAvatar(gen);
+      return;
+    }
+    try {
+      await this.withTimeout(
+        this.tsClient.fileTransferDeleteFile(0n, ["/avatar"]),
+        FILE_TRANSFER_TIMEOUT_MS,
+      );
+    } catch {
+      // File may not exist or transfer timed out — that's fine
+    }
+    if (this.generation !== gen) return;
+    try {
+      await this.tsClient.sendCommandNoWait("clientupdate client_flag_avatar=");
+    } catch (err) {
+      this.handleFeatureError("avatar", err);
+    }
+  }
+```
+
+4. Add a new private method right below `clearAvatar`:
+
+```ts
+  private async applyIdleAvatar(gen: number): Promise<void> {
+    if (!this.customAvatar || this.customAvatar.length === 0) return;
+    if (this.permDenied.avatar) return;
+    try {
+      await this.withTimeout(this.doAvatarUpload(this.customAvatar), FILE_TRANSFER_TIMEOUT_MS);
+      if (this.generation !== gen) return;
+      this.logger.info({ bytes: this.customAvatar.length }, "Idle (custom) avatar applied");
+    } catch (err) {
+      this.handleFeatureError("avatar", err);
+    }
+  }
+```
+
+5. Find `onConnect` (the existing method that resets per-feature flags). At its end, immediately after the `permDenied` reset, add:
+
+```ts
+    if (!this.config.avatarEnabled && this.customAvatar) {
+      const gen = ++this.generation;
+      void this.applyIdleAvatar(gen);
+    }
+```
+
+If `onConnect` does not exist as a method, search for where reconnect resets `permDenied` and add the block there.
+
+- [ ] **Step 5: Run test to verify it passes**
+
+Run: `npx vitest run src/bot/profile.test.ts`
+Expected: PASS — 5/5
+
+Run also: `npx vitest run src/audio src/data src/bot` — confirm no regressions.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/profile.ts src/bot/profile.test.ts
+git commit -m "feat(profile): custom avatar with idle/playback precedence"
+```
+
+---
+
+### Task 4: Wire avatar load on bot start
+
+**Files:**
+- Modify: `src/bot/instance.ts`
+- Modify: `src/bot/manager.ts` (if it constructs the instance)
+- Modify: `src/index.ts`
+
+- [ ] **Step 1: Confirm where `BotProfileManager` is constructed and how `BotInstance` receives DB**
+
+Run: `grep -n 'new BotProfileManager\|profileManager =\|database\|botDb' src/bot/instance.ts src/bot/manager.ts | head -20`
+
+Identify the BotInstance constructor params and verify that the DB and the avatar dir can flow in.
+
+- [ ] **Step 2: Add `AVATAR_DIR` constant + `avatarStore` to `src/index.ts`**
+
+Find where `COOKIE_DIR` / `createCookieStore` are set up (~line 48 in src/index.ts) and add directly after:
+
+```ts
+const AVATAR_DIR = process.env.AVATAR_DIR ?? join(DATA_DIR, "avatars");
+const avatarStore = createAvatarStore(AVATAR_DIR);
+```
+
+(import as needed: `import { createAvatarStore } from "./data/avatars.js";`)
+
+Pass `avatarStore` through to whatever constructs `BotManager` (and from there to `BotInstance`).
+
+- [ ] **Step 3: In `BotInstance`, after `profileManager` is created, load the avatar from disk if any**
+
+In `src/bot/instance.ts`, after `this.profileManager = new BotProfileManager(...)`:
+
+```ts
+const relPath = this.botDb.getCustomAvatarPath(this.id);
+if (relPath) {
+  const buf = this.avatarStore.read(relPath);
+  if (buf) this.profileManager.setCustomAvatar(buf);
+}
+```
+
+(Add `private botDb: BotDatabase` and `private avatarStore: AvatarStore` constructor params; thread them down from `BotManager.createBot()` / `BotManager` constructor.)
+
+- [ ] **Step 4: Add `getProfileManager()` accessor if not present**
+
+If grep already shows `getProfileManager(): BotProfileManager`, skip. Otherwise add a public method that returns `this.profileManager`.
+
+- [ ] **Step 5: Build and run the existing tests**
+
+Run: `npx tsc --noEmit`
+Expected: no TS errors
+
+Run: `npm test`
+Expected: all green
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/index.ts src/bot/instance.ts src/bot/manager.ts
+git commit -m "feat(bot): load custom avatar on instance startup"
+```
+
+---
+
+### Task 5: REST endpoints for avatar upload / fetch / delete
+
+**Files:**
+- Modify: `src/web/server.ts` (json size limit)
+- Modify: `src/web/api/bot.ts`
+
+- [ ] **Step 1: Bump express.json size limit**
+
+In `src/web/server.ts`, find `app.use(express.json())` (~line 46) and change to:
+
+```ts
+app.use(express.json({ limit: "400kb" }));
+```
+
+(Avatar payload is base64-encoded ≤200 KB → ~270 KB on the wire; 400 KB gives margin.)
+
+- [ ] **Step 2: Write a failing API test (use supertest if not present, otherwise inline fetch)**
+
+Run: `grep -E '"supertest"|"vitest"' package.json`
+
+If supertest is not present, write the test using `node:http` raw client or skip API integration test and rely on manual + unit tests on Task 7. Don't add new deps unless approved.
+
+If supertest IS present, add `src/web/api/bot.test.ts`:
+
+```ts
+import { describe, it, expect } from "vitest";
+import request from "supertest";
+import express from "express";
+import { createBotRouter } from "./bot.js";
+// ... build minimal app with mocked manager + DB + avatarStore
+```
+
+If not present: skip Step 2, jump to Step 3 and verify by manual curl in Step 5.
+
+- [ ] **Step 3: Add the three endpoints**
+
+In `src/web/api/bot.ts`, modify the factory signature to accept `avatarStore` and `botDb`:
+
+```ts
+export function createBotRouter(
+  botManager: BotManager,
+  config: BotConfig,
+  configPath: string,
+  logger: Logger,
+  botDb: BotDatabase,
+  avatarStore: AvatarStore,
+): Router {
+```
+
+Inside the router, after the existing `/:id/config` GET, add:
+
+```ts
+  router.get("/:id/avatar", (req, res) => {
+    const path = botDb.getCustomAvatarPath(req.params.id);
+    if (!path) { res.status(404).end(); return; }
+    const buf = avatarStore.read(path);
+    if (!buf) { res.status(404).end(); return; }
+    const ext = path.split(".").pop()!;
+    const mime = ext === "png" ? "image/png" : ext === "webp" ? "image/webp" : "image/jpeg";
+    res.set("Content-Type", mime);
+    res.set("Cache-Control", "no-cache");
+    res.send(buf);
+  });
+
+  router.put("/:id/avatar", (req, res) => {
+    const bot = botManager.getBot(req.params.id);
+    if (!bot && !botDb.getBotInstances().some((b) => b.id === req.params.id)) {
+      res.status(404).json({ error: "Bot not found" });
+      return;
+    }
+    const { dataUrl } = req.body as { dataUrl?: string };
+    if (typeof dataUrl !== "string") {
+      res.status(400).json({ error: "dataUrl required" });
+      return;
+    }
+    const m = /^data:(image\/(png|jpeg|webp));base64,(.+)$/.exec(dataUrl);
+    if (!m) {
+      res.status(400).json({ error: "dataUrl must be image/png|jpeg|webp base64" });
+      return;
+    }
+    const mime = m[1];
+    const buf = Buffer.from(m[3], "base64");
+    if (buf.length > 200 * 1024) {
+      res.status(413).json({ error: "avatar exceeds 200KB limit" });
+      return;
+    }
+    const rel = avatarStore.write(req.params.id, mime, buf);
+    botDb.setCustomAvatarPath(req.params.id, rel);
+    bot?.getProfileManager().setCustomAvatar(buf);
+    res.json({ path: rel });
+  });
+
+  router.delete("/:id/avatar", (req, res) => {
+    const path = botDb.getCustomAvatarPath(req.params.id);
+    if (path) avatarStore.remove(path);
+    botDb.setCustomAvatarPath(req.params.id, null);
+    const bot = botManager.getBot(req.params.id);
+    bot?.getProfileManager().setCustomAvatar(null);
+    res.status(204).end();
+  });
+```
+
+- [ ] **Step 4: Update the call site that constructs the router**
+
+Search: `grep -n 'createBotRouter' src/`
+
+In the call site (likely `src/web/server.ts` or `src/index.ts`), pass the new args. Fix the call signature.
+
+- [ ] **Step 5: Manual smoke test**
+
+Run: `npm run build && npm run start`
+In another terminal:
+
+```bash
+# create a small valid PNG (1x1) base64
+B64=$(node -e "console.log(Buffer.from([137,80,78,71,13,10,26,10,0,0,0,13,73,72,68,82,0,0,0,1,0,0,0,1,8,2,0,0,0,144,119,83,222,0,0,0,12,73,68,65,84,8,153,99,248,255,255,63,0,5,254,2,254,205,250,236,184,0,0,0,0,73,69,78,68,174,66,96,130]).toString('base64'))")
+
+curl -X PUT http://localhost:3000/api/bot/<BOT_ID>/avatar \
+  -H 'Content-Type: application/json' \
+  -d "{\"dataUrl\":\"data:image/png;base64,$B64\"}"
+
+curl http://localhost:3000/api/bot/<BOT_ID>/avatar -o /tmp/x.png
+file /tmp/x.png
+
+curl -X DELETE http://localhost:3000/api/bot/<BOT_ID>/avatar -i
+```
+
+Expected: PUT returns `{"path":"<id>.png"}`, GET returns the bytes, DELETE returns 204.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/web/server.ts src/web/api/bot.ts src/index.ts
+git commit -m "feat(api): /api/bot/:id/avatar GET/PUT/DELETE"

+
+### Task 6: Frontend — `AvatarUpload.vue` component
+
+**Files:**
+- Create: `web/src/components/AvatarUpload.vue`
+
+- [ ] **Step 1: Create the component**
+
+```vue
+<template>

+```
+
+- [ ] **Step 2: Verify the component compiles**
+
+Run: `cd web && npx vue-tsc --noEmit`
+Expected: no errors
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add web/src/components/AvatarUpload.vue
+git commit -m "feat(web): AvatarUpload component"
+```
+
+---
+
+### Task 7: Wire AvatarUpload into Settings.vue (create + edit + standalone row)
+
+**Files:**
+- Modify: `web/src/views/Settings.vue`
+
+- [ ] **Step 1: Read the relevant Settings.vue regions**
+
+```bash
+grep -n '同步头像\|openEditBot\|saveEditBot\|createBot\|create-bot\|profile-features\|features.find' web/src/views/Settings.vue | head -20
+```
+
+Identify:
+- Create-bot form template region (`<div class="create-bot">` block)
+- Edit-bot modal/dialog template region
+- The profile features table where `avatarEnabled` row lives
+
+- [ ] **Step 2: Add component import + reactive state for avatar dataUrl on the create-bot form**
+
+In the script setup region, near other `newBot*` refs:
+
+```ts
+import AvatarUpload from '../components/AvatarUpload.vue';
+const newBotAvatar = ref<string | null>(null);
+```
+
+- [ ] **Step 3: Insert `<AvatarUpload v-model="newBotAvatar" />` into the create-bot form template**
+
+In the `<div class="create-bot">` block, right before `<button class="btn-primary" @click="createBot">创建</button>`, add:
+
+```vue
+        <div class="form-row">
+          <label>自定义头像（可选）</label>
+          <AvatarUpload v-model="newBotAvatar" />
+        </div>
+```
+
+- [ ] **Step 4: After successful `createBot()`, PUT the avatar if set**
+
+Find the `createBot` async function. After the POST resolves and the bot id is known (`res.data.id` or similar), append:
+
+```ts
+if (newBotAvatar.value) {
+  await axios.put(`/api/bot/${res.data.id}/avatar`, { dataUrl: newBotAvatar.value });
+}
+newBotAvatar.value = null;
+```
+
+- [ ] **Step 5: Add an "自定义头像" row in the per-bot profile features table**
+
+Find the profile-features table render (look for the `features` array iteration). The cleanest path: add a custom row OUTSIDE the array (since it isn't a boolean toggle). Right before `</template>` of the bot row, add:
+
+```vue
+        <div class="feature-row">
+          <div class="feature-label">自定义头像</div>
+          <div class="feature-control">
+            <CustomAvatarRow :bot-id="bot.id" />
+          </div>
+        </div>
+```
+
+Where `CustomAvatarRow` is an inline-defined component or a small file `web/src/components/CustomAvatarRow.vue` that:
+- Mounts → `axios.get(/api/bot/<id>/avatar, { responseType: 'blob' })` → previews if 200, ignore 404
+- Wraps `<AvatarUpload>` and on `update:modelValue`:
+  - If string → `axios.put(/avatar, { dataUrl })`
+  - If null → `axios.delete(/avatar)`
+
+Create `web/src/components/CustomAvatarRow.vue` with that logic; keep its body small (~50 lines).
+
+- [ ] **Step 6: Build and visually verify**
+
+Run: `cd web && npm run build` → no errors. Then `npm run dev` → open create-instance, upload PNG, create — verify the avatar appears on the bot in TS3 once it connects. Check edit/Settings flow.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add web/src/views/Settings.vue web/src/components/CustomAvatarRow.vue
+git commit -m "feat(web): custom avatar in create-bot + Settings"
+```
+
+---
+
+### Task 8: Open PR
+
+- [ ] **Step 1: Push the branch**
+
+```bash
+git checkout -b feat/custom-bot-avatar
+git push -u origin feat/custom-bot-avatar
+```
+
+(If commits were already on `main`, instead create the branch from the first relevant commit and reset main: `git branch feat/custom-bot-avatar HEAD && git reset --hard origin/main && git checkout feat/custom-bot-avatar`. The exact sequence depends on the working state when starting.)
+
+- [ ] **Step 2: Create the PR**
+
+```bash
+gh pr create --title "feat(profile): custom bot avatar" --body "Closes part of #51 (avatar half).
+
+## Summary
+- New /api/bot/:id/avatar GET/PUT/DELETE
+- BotProfileManager: custom avatar acts as idle image; cover sync still wins during playback when avatarEnabled=true
+- AvatarUpload component used in create-bot form and Settings per-bot row
+- Bump express.json limit to 400kb to allow base64 payload

+# Account Permissions Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let an admin grant each member account a set of capabilities and a list of bots they may control, enforced on the backend.
+
+**Architecture:** Capability tokens + per-member bot allow-list stored in two new SQLite tables, loaded onto `req.user` per request (live, no re-login), enforced by `requirePermission` / `requireBotAccess` middleware mirroring the existing `requireAdmin`. Admin stays a super-user. Existing members are backfilled to full access on upgrade; new members get a basic tier. The Vue UI hides what a member can't do and gives admins a permission editor.
+
+**Tech Stack:** Node ESM + TypeScript, Express, better-sqlite3, Vitest + supertest, Vue 3 + Pinia.
+
+**Spec:** `docs/superpowers/specs/2026-05-30-account-permissions-design.md`
+
+**Conventions:** All file paths are repo-relative. Tests run with `npx vitest run <path>`. Backend is TDD (test first, watch fail, implement, watch pass, commit). Commit after each task.
+
+---
+
+## File Structure
+
+**Create:**
+- `src/data/permissions.ts` — capability constants + `PermissionStore` (tables accessed here)
+- `src/data/permissions.test.ts` — store + constants tests
+- `src/web/middleware/requirePermission.ts` — `requirePermission(cap)` + `requireBotAccess(param)`
+- `src/web/middleware/requirePermission.test.ts` — middleware tests
+
+**Modify:**
+- `src/data/database.ts` — `initTables`: add the two tables + index; migration backfill of existing members
+- `src/data/audit.ts` — add `"user.permissions_changed"` to `AuditAction`
+- `src/web/middleware/requireAuth.ts` — widen `req.user`; load capabilities + bot access
+- `src/web/auth/validateSession.ts` — (no change; just confirm) — actually unchanged
+- `src/web/api/session.ts` — `/me` returns capabilities + bots; inline auth attaches them
+- `src/web/server.ts` — construct `PermissionStore`, pass into routers/middleware
+- `src/web/api/player.ts` — `requireBotAccess` on `/:botId`; per-route `requirePermission`
+- `src/web/api/bot.ts` — `requirePermission("bot.manage")` + `requireBotAccess("id")`
+- `src/web/api/auth.ts` — `requirePermission("platform.auth")`
+- `src/web/api/music.ts` — `requirePermission("quality")` on the quality POST; filter `GET /api/bot`? no — bot list is in bot.ts
+- `src/web/api/bot.ts` — filter `GET /` to allowed bots for members
+- `src/web/api/users.ts` — `GET/PUT /api/users/:id/permissions`
+- `src/bot/manager.ts` — `removeBot` calls `permissions.pruneBot(botId)`

+
+- [ ] **Step 4: Add tables in `src/data/database.ts` initTables**
+
+Find `initTables` (creates users/sessions/user_audit). Add, after the `user_audit` CREATE:
+
+```typescript
+  db.exec(`
+    CREATE TABLE IF NOT EXISTS user_permissions (
+      userId     TEXT NOT NULL,
+      permission TEXT NOT NULL,
+      PRIMARY KEY (userId, permission),
+      FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+    );
+    CREATE TABLE IF NOT EXISTS user_bot_access (
+      userId TEXT NOT NULL,
+      botId  TEXT NOT NULL,
+      PRIMARY KEY (userId, botId),
+      FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+    );
+    CREATE INDEX IF NOT EXISTS idx_user_bot_access_userId ON user_bot_access(userId);
+  `);
+```
+
+(If `initTables` uses individual `db.exec` calls, match that style. The `BotDatabase` type already exposes `.db` and `.close()` — confirm by reading the file; the test uses `db.db` and `db.close()`.)
+
+- [ ] **Step 5: Run tests to verify they pass**
+
+Run: `npx vitest run src/data/permissions.test.ts`
+Expected: PASS (7 tests).
+
+- [ ] **Step 6: Commit**
+
+```bash

+
+**Files:**
+- Create: `src/web/middleware/requirePermission.ts`
+- Create: `src/web/middleware/requirePermission.test.ts`
+- Modify: `src/web/middleware/requireAuth.ts` (widen `req.user`)
+
+- [ ] **Step 1: Widen the `req.user` augmentation in `src/web/middleware/requireAuth.ts`**
+
+Change the `declare module` block so `req.user` carries capabilities + bot access:
+
+```typescript
+declare module "express-serve-static-core" {
+  interface Request {
+    user?: {
+      id: string;
+      username: string;
+      role: "admin" | "member";
+      capabilities: Set<string>;
+      bots: "all" | Set<string>;
+    };
+  }
+}
+```
+
+(The loading of these fields is done in Task 4 — for now this only widens the type. Existing assignments to `req.user` will fail to typecheck until Task 4; that is expected and Task 4 fixes them. If you need the build green between tasks, do Task 2 + Task 4 back-to-back before running `tsc`.)

+
+**Files:**
+- Modify: `src/data/permissions.ts` (add `resolveContext` helper)
+- Modify: `src/data/permissions.test.ts` (add tests)

+});
+```
+
+- [ ] **Step 2: Run to verify fail**
+
+Run: `npx vitest run src/data/permissions.test.ts`
+Expected: FAIL — `resolvePermissionContext` not exported.

+
+**Files:**
+- Modify: `src/web/middleware/requireAuth.ts`
+- Modify: `src/web/api/session.ts`
+- Modify: `src/web/server.ts`
+
+- [ ] **Step 1: Thread `PermissionStore` into `createRequireAuth`**
+
+`src/web/middleware/requireAuth.ts` — change the factory signature and set the new fields:
+
+```typescript
+import { resolvePermissionContext, type PermissionStore } from "../../data/permissions.js";
+
+export function createRequireAuth(sessions: SessionStore, permissions: PermissionStore): RequestHandler {
+  return function requireAuth(req, res, next) {
+    const result = validateSessionFromHeaders(req.headers.cookie, sessions);
+    if (!result) {
+      res.clearCookie(SESSION_COOKIE_NAME, { path: "/" });
+      res.status(401).json({ error: "unauthenticated" });
+      return;
+    }
+    const ctx = resolvePermissionContext(result.role, result.userId, permissions);
+    req.user = {
+      id: result.userId, username: result.username, role: result.role,
+      capabilities: ctx.capabilities, bots: ctx.bots,
+    };
+    const token = extractSessionToken(req.headers.cookie);
+    if (token) {
+      res.cookie(SESSION_COOKIE_NAME, token, {
+        httpOnly: true, sameSite: "lax", secure: req.secure, path: "/", maxAge: SESSION_TTL_MS,
+      });
+    }
+    next();
+  };
+}
+```
+
+- [ ] **Step 2: Update `src/web/server.ts`**
+
+Construct the store next to the others and pass it in:
+
+```typescript
+import { createPermissionStore } from "../data/permissions.js";
+// ...
+const permissions = createPermissionStore(options.database.db);
+// ...
+const requireAuth = createRequireAuth(sessions, permissions);
+```
+
+Keep `permissions` in scope — it's passed to routers in Tasks 5–7.
+
+- [ ] **Step 3: Update session inline auth + `/me` in `src/web/api/session.ts`**
+
+`createSessionRouter` must accept `permissions` and (a) attach capabilities in `requireAuthInline`, (b) include them in `/me`. Pass `permissions` from `server.ts` into `createSessionRouter(users, sessions, audit, logger, permissions)`. In the `/me` handler, return:
+
+```typescript
+const ctx = resolvePermissionContext(validation.role, validation.userId, permissions);
+res.json({
+  id: validation.userId, username: validation.username, role: validation.role,
+  capabilities: [...ctx.capabilities],
+  bots: ctx.bots === "all" ? "all" : [...ctx.bots],
+});
+```
+
+(Match the existing `/me` shape; just add `capabilities` + `bots`. Read the file to find the exact response object.)
+
+- [ ] **Step 4: Verify build + existing tests**
+
+Run: `npx tsc --noEmit`
+Expected: exit 0 (the widened `req.user` is now populated everywhere it's read).
+
+Run: `npx vitest run src/web`
+Expected: PASS (existing auth/session/csrf tests still green; if a test constructs `createRequireAuth(sessions)` it must be updated to pass a `createPermissionStore(db)`).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/web/middleware/requireAuth.ts src/web/server.ts src/web/api/session.ts
+git commit -m "feat(perm): load capabilities + bot access onto req.user; expose via /me"
+```

+
+## Task 5: Enforce capabilities on the action routes
+
+**Files:**
+- Modify: `src/web/api/player.ts`, `src/web/api/bot.ts`, `src/web/api/auth.ts`, `src/web/api/music.ts`
+- Modify: `src/web/api/player.test.ts` (or create `src/web/api/permissions-enforcement.test.ts`)
+
+- [ ] **Step 1: Write a failing integration test** at `src/web/api/permissions-enforcement.test.ts` that builds the real app (or the relevant router) with a stubbed `req.user` and asserts:
+  - member without `player.control` → `POST /api/player/:botId/pause` → 403
+  - member with `player.control` + bot in allow-list → 200 (bot resolves)
+  - member with `player.control` but bot NOT in allow-list → 403
+  - member without `player.queue` → `POST /api/player/:botId/clear` → 403
+  - member without `bot.manage` → `POST /api/bot` → 403
+  - member without `platform.auth` → `POST /api/auth/cookie` → 403
+  - member without `quality` → `POST /api/music/quality` → 403
+  - admin → all 200/allowed
+
+  Use the same `appWith(user)` injection pattern as Task 2 (insert a middleware that sets `req.user` before the router) and a fake `BotManager`/providers so routes resolve. Model it on the existing `src/web/api/*.test.ts` setup (read one first for the harness).
+
+- [ ] **Step 2: Run to verify fail** — `npx vitest run src/web/api/permissions-enforcement.test.ts` → FAIL (routes currently allow everyone).
+
+- [ ] **Step 3: Apply gates.**
+
+`src/web/api/player.ts` — the shared `/:botId` middleware already resolves the bot. Add bot-access there, and add per-action capability guards. Define the queue-capability routes vs control routes:
+
+```typescript
+import { requirePermission, requireBotAccess } from "../middleware/requirePermission.js";
+
+// after the existing router.use("/:botId", resolveBot):
+router.use("/:botId", requireBotAccess("botId"));
+
+const control = requirePermission("player.control");
+const queue = requirePermission("player.queue");
+// control: play, pause, resume, next, prev, stop, seek, volume, mode, play-song, play-at, play-by-id, play-playlist, play-album, play-next-song
+// queue:   add, add-song, add-by-id, clear, playlist, /queue/:index (DELETE)
+// Apply per route, e.g.:
+router.post("/:botId/pause", control, async (req, res) => { /* existing */ });
+router.post("/:botId/add", queue, async (req, res) => { /* existing */ });
+router.delete("/:botId/queue/:index", queue, async (req, res) => { /* existing */ });
+```
+
+(Insert the `control`/`queue` middleware as the 2nd arg of each existing `router.post/delete`. Do not change handler bodies. `PUT /:botId/profile` → `requirePermission("bot.manage")`.)
+
+`src/web/api/bot.ts` — gate management + per-bot:
+
+```typescript
+const manage = requirePermission("bot.manage");
+router.post("/", manage, ...);                 // create (no botId)
+router.put("/:id", manage, requireBotAccess("id"), ...);
+router.delete("/:id", manage, requireBotAccess("id"), ...);
+router.post("/:id/start", manage, requireBotAccess("id"), ...);
+router.post("/:id/stop", manage, requireBotAccess("id"), ...);
+router.put("/:id/avatar", manage, requireBotAccess("id"), ...);
+router.delete("/:id/avatar", manage, requireBotAccess("id"), ...);
+router.post("/settings", manage, ...);         // global idle timeout
+```
+
+`src/web/api/auth.ts` — gate every mutating route with `requirePermission("platform.auth")`:
+`POST /qrcode`, `POST /sms/send`, `POST /sms/verify`, `POST /cookie`. (Leave `GET /status`, `GET /qrcode/status` open — read-only.)
+
+`src/web/api/music.ts` — gate the one mutating route:
+`router.post("/quality", requirePermission("quality"), ...)`.
+
+- [ ] **Step 4: Run to verify pass** — `npx vitest run src/web/api/permissions-enforcement.test.ts` → PASS. Then `npx vitest run src/web` → all green.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/web/api/player.ts src/web/api/bot.ts src/web/api/auth.ts src/web/api/music.ts src/web/api/permissions-enforcement.test.ts

+- Modify: `src/bot/manager.ts` (`removeBot` → `permissions.pruneBot`)
+- Modify: test from Task 5

+- [ ] **Step 1: Add failing test** — member with `bots: ["b1"]` calling `GET /api/bot` sees only `b1`; admin sees all.
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement.** In `GET /` of `bot.ts`:
+
+```typescript
+const all = getAllBots().map((b) => b.getStatus());
+const u = req.user!;

+  ? all
+  : all.filter((b) => (u.bots as Set<string>).has(b.id));
+res.json({ bots });
+```
+
+In `src/bot/manager.ts`, give `BotManager` access to the `PermissionStore` (constructor param) and call `this.permissions.pruneBot(id)` inside `removeBot(id)` after deletion, so deleted bots drop out of allow-lists. Thread `permissions` from `index.ts`/`server.ts` into `BotManager`.

+
+- [ ] **Step 1: Add `"user.permissions_changed"`** to the `AuditAction` union in `src/data/audit.ts`.
+
+- [ ] **Step 2: Write failing tests** for the users router (admin-only):
+  - `GET /api/users/:id/permissions` → `{ capabilities: [], bots: [] }` for a fresh member.
+  - `PUT /api/users/:id/permissions` with `{capabilities:["player.control"], bots:"all"}` → 200; subsequent GET reflects it; an audit row `user.permissions_changed` exists.
+  - `PUT` with an unknown capability token → it is dropped (not stored).
+  - New member created via `POST /api/users` → GET permissions returns basic tier (`["player.control","player.queue"]`, bots `"all"`).

+## Task 8: One-time migration backfill (existing members → full)
+
+**Files:**
+- Modify: `src/data/database.ts` (`migrateSchema` or a dedicated backfill)
+- Create: `src/data/permissions-migration.test.ts`
+
+- [ ] **Step 1: Write failing test** — given a fresh db with an existing `member` user and NO permission rows, after `createDatabase()` runs the backfill, that member has all 5 capabilities + `bots.all`; an `admin` user gets nothing (bypasses). Backfill is idempotent (running twice does not duplicate / does not re-grant a member who was later restricted to empty).
+
+  Idempotency approach: store a one-shot marker. Use a `meta` row or check: only backfill members who currently have ZERO permission rows AND only on first introduction. Simplest robust marker: a row in a tiny `schema_meta(key TEXT PK, value TEXT)` table, key `perm_backfill_done`. If present, skip.
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement** a `backfillMemberPermissions(db)` run once inside `createDatabase` after `initTables`:
+
+```typescript
+db.exec(`CREATE TABLE IF NOT EXISTS schema_meta (key TEXT PRIMARY KEY, value TEXT)`);
+const done = db.prepare("SELECT value FROM schema_meta WHERE key = 'perm_backfill_done'").get();
+if (!done) {
+  const members = db.prepare("SELECT id FROM users WHERE role = 'member'").all() as { id: string }[];
+  const insCap = db.prepare("INSERT OR IGNORE INTO user_permissions (userId, permission) VALUES (?, ?)");
+  const tx = db.transaction(() => {
+    for (const m of members) {
+      for (const c of ["player.control","player.queue","bot.manage","platform.auth","quality","bots.all"]) {
+        insCap.run(m.id, c);
+      }
+    }
+    db.prepare("INSERT INTO schema_meta (key, value) VALUES ('perm_backfill_done', ?)").run(String(Date.now()));
+  });
+  tx();
+}
+```
+
+- [ ] **Step 4: Run → pass.**
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/data/database.ts src/data/permissions-migration.test.ts
+git commit -m "feat(perm): one-time backfill of existing members to full access"
+```
+
+---
+
+## Task 9: Frontend — session capabilities + helpers
+
+**Files:**
+- Modify: `web/src/composables/useSession.ts`
+
+- [ ] **Step 1:** Extend the `User` type with `capabilities: string[]` and `bots: 'all' | string[]`; populate from `/api/session/me`, `/login`, `/setup` responses (the backend now returns them).
+- [ ] **Step 2:** Add computed helpers:
+
+```typescript
+function can(cap: string): boolean {
+  const u = currentUser.value;
+  return !!u && (u.role === 'admin' || (u.capabilities ?? []).includes(cap));
+}
+function canControlBot(botId: string): boolean {
+  const u = currentUser.value;
+  if (!u) return false;
+  if (u.role === 'admin' || u.bots === 'all') return true;
+  return Array.isArray(u.bots) && u.bots.includes(botId);
+}
+```
+
+Export `can` and `canControlBot` from the composable.
+
+- [ ] **Step 3:** Manual check: log in as admin → `can('quality')` true; (after backend done) a restricted member → false. Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 4: Commit** `git add web/src/composables/useSession.ts && git commit -m "feat(perm): frontend session capabilities + can()/canControlBot()"`
+
+---
+
+## Task 10: Frontend — gate UI by capability + filter bots
+
+**Files:**
+- Modify: `web/src/components/Navbar.vue`, `web/src/components/Player.vue`, `web/src/views/Settings.vue`, `web/src/stores/player.ts`
+
+- [ ] **Step 1:** Navbar bot selector: render only controllable bots — `v-for="bot in store.bots"` becomes a filtered computed `controllableBots = store.bots.filter(b => session.canControlBot(b.id))`. (The backend already filters `GET /api/bot`, so this is belt-and-suspenders + correctness if both lists diverge.) Ensure `store.activeBot` fallback never lands on a bot the user can't control.
+- [ ] **Step 2:** Player.vue: wrap control buttons with `v-if="session.can('player.control')"` and queue actions with `v-if="session.can('player.queue')"`.
+- [ ] **Step 3:** Settings.vue: wrap the platform login cards with `v-if="session.can('platform.auth')"`, the audio-quality control with `v-if="session.can('quality')"`, and bot create/edit/delete with `v-if="session.can('bot.manage')"`.
+- [ ] **Step 4:** Manual verification (see Verification section). Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 5: Commit** `git add web/src/components/Navbar.vue web/src/components/Player.vue web/src/views/Settings.vue web/src/stores/player.ts && git commit -m "feat(perm): hide UI a member lacks capability for"`
+
+---
+
+## Task 11: Frontend — admin permission editor
+
+**Files:**
+- Modify: `web/src/views/Settings.vue` (User Management section)
+
+- [ ] **Step 1:** In each member row of the admin User-Management list, add a "权限" button opening an editor (inline panel or dialog) with: 5 capability checkboxes (labels: 播放控制 / 队列管理 / 机器人管理 / 平台登录凭据 / 音质设置), and a bot allow-list — an "全部机器人" toggle plus, when off, a checkbox per bot from `store.bots`.
+- [ ] **Step 2:** On open, `GET /api/users/:id/permissions`; on save, `PUT /api/users/:id/permissions` with `{capabilities, bots}` then re-fetch. Admin rows show "全部权限(管理员)" and no editor.
+- [ ] **Step 3:** Manual verification. Build: `cd web && npx vue-tsc --noEmit`.
+- [ ] **Step 4: Commit** `git add web/src/views/Settings.vue && git commit -m "feat(perm): admin permission editor in user management"`
+
+---
+
+## Final verification
+
+- [ ] `npx tsc --noEmit` → exit 0
+- [ ] `npx vitest run src/` → all green (clean-checkout-equivalent; ignore stale `dist/` twins — see note)
+- [ ] `cd web && npx vue-tsc --noEmit` → exit 0
+- [ ] `npm run build` → succeeds
+- [ ] Manual (run the bot, log in): admin sees everything; create a member, restrict to `player.control` on one bot → member sees only that bot, can play/pause but cannot add to queue, cannot open platform login / quality / bot management; backend returns 403 on a forged request to a disallowed action (verify with curl + the member's session cookie).
+
+> **Note (pre-existing):** `tsconfig.json` compiles `*.test.ts` into `dist/`, and vitest also runs the `dist/` twins after a build — so `npx vitest run` (no path) double-runs and can fail on stale artifacts. Scope verification to `npx vitest run src/`. (A separate cleanup PR could add `exclude: ['**/dist/**']` to a vitest config.)

+# Auto-pause on Empty Channel — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Auto-pause playback when the bot's channel empties (no disconnect) and auto-resume when someone returns — only resuming tracks we auto-paused — gated by the existing global `autoPauseOnEmpty` flag.
+
+**Architecture:** A pure decision function decides pause/resume from (player state, autoPaused, flag, userCount). `BotInstance` owns an `autoPaused` flag and a `checkChannelOccupancy()` that the existing 30s idle poll AND new TS enter/leave/move events both call. The toggle is wired into `/api/bot/settings` + the Settings UI.
+
+**Tech:** Node ESM + TS, Vitest, Express, Vue 3.
+
+**Spec:** `docs/superpowers/specs/2026-05-30-autopause-empty-channel-design.md`
+
+---
+
+## Task 1: Pure occupancy-decision function
+
+**Files:** Create `src/bot/auto-pause.ts`, `src/bot/auto-pause.test.ts`.
+
+- [ ] **Step 1 — failing test** `src/bot/auto-pause.test.ts`:
+
+```typescript
+import { describe, it, expect } from "vitest";
+import { decideOccupancyAction } from "./auto-pause.js";
+
+describe("decideOccupancyAction", () => {
+  // (playerState, autoPaused, enabled, userCount) => "pause" | "resume" | "none"
+  it("pauses when empty while playing and enabled", () => {
+    expect(decideOccupancyAction("playing", false, true, 0)).toBe("pause");
+  });
+  it("does not pause when the feature is disabled", () => {
+    expect(decideOccupancyAction("playing", false, false, 0)).toBe("none");
+  });
+  it("does not pause when idle (nothing playing)", () => {
+    expect(decideOccupancyAction("idle", false, true, 0)).toBe("none");
+  });
+  it("does not pause when already paused", () => {
+    expect(decideOccupancyAction("paused", false, true, 0)).toBe("none");
+  });
+  it("resumes when re-populated and we auto-paused", () => {
+    expect(decideOccupancyAction("paused", true, true, 2)).toBe("resume");
+  });
+  it("does NOT resume a user-paused track on re-population", () => {
+    expect(decideOccupancyAction("paused", false, true, 2)).toBe("none");
+  });
+  it("does nothing when re-populated and already playing", () => {
+    expect(decideOccupancyAction("playing", false, true, 2)).toBe("none");
+  });
+  it("resume is independent of the enabled flag (we already auto-paused)", () => {
+    expect(decideOccupancyAction("paused", true, false, 1)).toBe("resume");
+  });
+});
+```
+
+- [ ] **Step 2 — run, expect fail:** `npx vitest run src/bot/auto-pause.test.ts` → module missing.
+
+- [ ] **Step 3 — implement** `src/bot/auto-pause.ts`:
+
+```typescript
+export type PlayerStateName = "idle" | "playing" | "paused";
+export type OccupancyAction = "pause" | "resume" | "none";
+
+/**
+ * Decide what auto-pause should do given the channel occupancy.
+ * - empty (userCount <= 0): pause iff enabled and currently playing.
+ * - re-populated (userCount > 0): resume iff we previously auto-paused and are still paused.
+ * `autoPaused` distinguishes our auto-pause from a user pause, so user pauses are never resumed.
+ */
+export function decideOccupancyAction(
+  playerState: PlayerStateName,
+  autoPaused: boolean,
+  enabled: boolean,
+  userCount: number,
+): OccupancyAction {
+  const empty = userCount <= 0;
+  if (empty) {
+    if (enabled && playerState === "playing") return "pause";
+    return "none";
+  }
+  if (autoPaused && playerState === "paused") return "resume";
+  return "none";
+}
+```
+
+- [ ] **Step 4 — run, expect pass:** `npx vitest run src/bot/auto-pause.test.ts` → 8 pass.
+- [ ] **Step 5 — commit:** `git add src/bot/auto-pause.ts src/bot/auto-pause.test.ts && git commit -m "feat(autopause): pure occupancy-decision function"`
+
+---
+
+## Task 2: Wire decision into BotInstance (autoPaused flag + checkChannelOccupancy)
+
+**Files:** Modify `src/bot/instance.ts`.
+
+Context: `_startIdlePoller` (~lines 190-206) polls every 30s, computes `userCount = (await getClientsInChannel()).length - 1`, and calls `_scheduleIdleCheck()` (empty) / `_cancelIdleTimer()` (occupied). `cmdPause`/`cmdResume` (~484-494), `cmdStop` (~496-505), and the playback start (`cmdPlay`/resolveAndPlay) wrap `player`. There's an unused `channelUserCount` field (~line 68). The instance has `this.config` (BotConfig) and `this.player`.
+
+- [ ] **Step 1 — add state + helper.** Add a private field `private autoPaused = false;`. Create a method that centralizes occupancy handling and is called with a freshly-computed userCount:
+
+```typescript
+import { decideOccupancyAction } from "./auto-pause.js";
+
+private handleOccupancy(userCount: number): void {
+  // idle-disconnect (unchanged behavior)
+  if (userCount <= 0) this._scheduleIdleCheck();
+  else this._cancelIdleTimer();
+
+  // auto-pause
+  const action = decideOccupancyAction(
+    this.player.getState() as "idle" | "playing" | "paused",
+    this.autoPaused,
+    this.config.autoPauseOnEmpty,
+    userCount,
+  );
+  if (action === "pause") {
+    this.player.pause();
+    this.autoPaused = true;
+    this.emit("stateChange");
+  } else if (action === "resume") {
+    this.player.resume();
+    this.autoPaused = false;
+    this.emit("stateChange");
+  }
+}
+```
+
+- [ ] **Step 2 — route the idle poller through it.** In `_startIdlePoller`, replace the inline `userCount`→schedule/cancel logic with: compute `userCount` then `this.handleOccupancy(userCount)`. (Keep the 30s interval + the same getClientsInChannel call + error handling.) Remove the now-redundant inline schedule/cancel branch (it lives in `handleOccupancy`).
+
+- [ ] **Step 3 — clear autoPaused on user actions + lifecycle.** In `cmdPause`, `cmdResume`, `cmdStop`, and the play-start path (`cmdPlay`/wherever playback (re)starts), set `this.autoPaused = false`. In the `disconnected` handler and on (re)connect, set `this.autoPaused = false`. (These ensure a user pause is never auto-resumed and the flag resets across connections.)
+
+- [ ] **Step 4 — `updateAutoPause`.** Add (mirrors `updateIdleTimeout`):
+
+```typescript
+updateAutoPause(enabled: boolean): void {
+  this.config.autoPauseOnEmpty = enabled;
+  // if turning off, leave current playback as-is; if a track was auto-paused, optionally resume:
+  if (!enabled && this.autoPaused && this.player.getState() === "paused") {
+    this.player.resume();
+    this.autoPaused = false;
+    this.emit("stateChange");
+  }
+}
+```
+
+- [ ] **Step 5 — verify:** `npx tsc --noEmit` → exit 0. `npx vitest run src/bot src/audio` → pass (existing tests unaffected).
+- [ ] **Step 6 — commit:** `git add src/bot/instance.ts && git commit -m "feat(autopause): drive pause/resume from channel occupancy in BotInstance"`
+
+---
+
+## Task 3: Re-emit TS member events for instant reaction
+
+**Files:** Modify `src/ts-protocol/client.ts`, `src/bot/instance.ts`.
+
+Context: `client.ts` forwards `textMessage`/`disconnected`/`connected` and only debug-logs `clientEnter` (~lines 219-224); `clientLeave`/`clientMoved` are not handled. `BotInstance.setupTsEvents()` (~lines 132-156) wires tsClient events.
+
+- [ ] **Step 1 — re-emit in client.ts.** Where `clientEnter` is logged, also `this.emit("clientEnter", info)`. Add subscriptions for `clientLeave` and `clientMoved` that `this.emit(...)` them upward (match the existing forwarding style; just propagate, no payload transformation needed since the instance re-queries).
+
+- [ ] **Step 2 — react in instance.ts.** In `setupTsEvents()`, add handlers: on `clientEnter` / `clientLeave` / `clientMoved`, call a small `async refreshOccupancy()` that does `const clients = await this.getClientsInChannel(); this.handleOccupancy(clients.length - 1);` (guarded with try/catch + only when connected). This gives near-instant pause/resume; the 30s poll remains the fallback.
+
+- [ ] **Step 3 — verify:** `npx tsc --noEmit` → 0. `npx vitest run src/bot` → pass.
+- [ ] **Step 4 — commit:** `git add src/ts-protocol/client.ts src/bot/instance.ts && git commit -m "feat(autopause): re-emit client enter/leave/move for instant pause/resume"`
+
+---
+
+## Task 4: API wiring for the toggle
+
+**Files:** Modify `src/web/api/bot.ts`; add/extend a test.
+
+Context: `GET /api/bot/settings` returns `{ idleTimeoutMinutes }`; `POST /api/bot/settings` validates `idleTimeoutMinutes`, sets `config.idleTimeoutMinutes`, `saveConfig`, then loops `botManager.getAllBots()` → `bot.updateIdleTimeout(...)`. This route is `requirePermission("bot.manage")`-gated.
+
+- [ ] **Step 1 — failing API test** (extend the existing bot settings test or add one): `GET /api/bot/settings` returns `autoPauseOnEmpty` (boolean); `POST /api/bot/settings` with `{ autoPauseOnEmpty: false }` persists it (a follow-up GET reflects false) and calls `updateAutoPause` on bots. Model the harness on the existing settings test.
+
+- [ ] **Step 2 — run, expect fail.**
+
+- [ ] **Step 3 — implement.** In `GET /settings`, add `autoPauseOnEmpty: options.config.autoPauseOnEmpty` to the response. In `POST /settings`, if `typeof req.body.autoPauseOnEmpty === "boolean"`, set `config.autoPauseOnEmpty`, include it in the `saveConfig`, and loop bots calling `bot.updateAutoPause(config.autoPauseOnEmpty)`. Keep the existing `idleTimeoutMinutes` handling intact (handle both fields in one save).
+
+- [ ] **Step 4 — verify:** `npx vitest run src/web` → pass; `npx tsc --noEmit` → 0.
+- [ ] **Step 5 — commit:** `git add src/web/api/bot.ts <test> && git commit -m "feat(autopause): expose autoPauseOnEmpty via /api/bot/settings"`
+
+---
+
+## Task 5: Frontend toggle in Settings
+
+**Files:** Modify `web/src/views/Settings.vue` (and the settings load/save it uses).
+
+Context: The **行为设置** section (already `v-if="can('bot.manage')"`) holds the idle-timeout control, loaded via `loadIdleTimeout()` (GET /api/bot/settings) and saved via `saveIdleTimeout()` (POST). Read these first.
+
+- [ ] **Step 1 — implement.** Add an `autoPauseOnEmpty` ref. In the settings load, populate it from the GET response. Add a checkbox/toggle in the 行为设置 section labelled e.g. "频道无人时自动暂停" bound to it, and include `autoPauseOnEmpty` in the POST payload of the save function (alongside `idleTimeoutMinutes`, or via its own save — match the existing pattern). Use existing form/toggle CSS classes.
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0; read template back for correctness.
+- [ ] **Step 3 — commit:** `git add web/src/views/Settings.vue && git commit -m "feat(autopause): autoPauseOnEmpty toggle in Settings"`
+
+---
+
+## Final verification
+- [ ] `npx tsc --noEmit` → 0
+- [ ] `npx vitest run src/` → all pass
+- [ ] `cd web && npx vue-tsc --noEmit` → 0
+- [ ] `npm run build` → succeeds
+- [ ] Manual: with a bot playing, leave its channel → music auto-pauses (no disconnect); rejoin → resumes. Manually pause, leave, rejoin → stays paused. Toggle off in Settings → no auto-pause.

+# Dedicated-link Bot Scoping (+ refresh fix) — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** Opening a dedicated link locks the WebUI to that one bot (selector shows only it, switching disabled, with an explicit exit); the lock is carried in the URL (`?bot=<id>`) so it survives refresh — fixing item 4 too.
+
+**Architecture:** A `scopedBotId` in the Pinia player store is the runtime lock; the URL query `?bot=<id>` is the durable source of truth. A router `beforeEach` syncs scope from the query and re-attaches `?bot` across in-app navigation while scoped. `BotRedirect` seeds it; Navbar renders the lock; graceful clear if the bot doesn't exist.
+
+**Tech:** Vue 3 + Pinia + vue-router, TypeScript. (Frontend isn't unit-tested in this repo → verify via `vue-tsc` + manual; extract one pure helper to unit-test.)
+
+**Spec:** `docs/superpowers/specs/2026-05-30-dedicated-link-scope-design.md`
+
+---
+
+## Task 1: Store scope state + pure resolve helper (with test)
+
+**Files:** Modify `web/src/stores/player.ts`; create `web/src/stores/scope.ts` + `web/src/stores/scope.test.ts`.
+
+READ `web/src/stores/player.ts` first: `activeBotId` state (~line 52), `setActiveBotId` action (~127-133), `fetchBots` (~196-198 default to bots[0]), `activeBot` getter (~73-75), and the localStorage pattern used by `theme` (~175-183) for reference (we are NOT using localStorage, but match code style).
+
+- [ ] **Step 1 — pure helper + failing test.** Create `web/src/stores/scope.ts`:
+
+```typescript
+/** Given the desired scoped id (from ?bot) and the known bot ids, decide the
+ * effective scope. Returns the id if it exists, else null (graceful clear:
+ * a stale/forbidden id never locks the UI). */
+export function resolveScopedBot(
+  requestedId: string | null | undefined,
+  knownBotIds: readonly string[],
+): string | null {
+  if (!requestedId) return null;
+  return knownBotIds.includes(requestedId) ? requestedId : null;
+}
+```
+
+`web/src/stores/scope.test.ts`:
+
+```typescript
+import { describe, it, expect } from "vitest";
+import { resolveScopedBot } from "./scope.js";
+
+describe("resolveScopedBot", () => {
+  it("returns null when no id requested", () => {
+    expect(resolveScopedBot(null, ["a", "b"])).toBeNull();
+    expect(resolveScopedBot(undefined, ["a"])).toBeNull();
+    expect(resolveScopedBot("", ["a"])).toBeNull();
+  });
+  it("returns the id when it exists in the bot list", () => {
+    expect(resolveScopedBot("b", ["a", "b"])).toBe("b");
+  });
+  it("clears (null) when the requested id is not a known bot", () => {
+    expect(resolveScopedBot("ghost", ["a", "b"])).toBeNull();
+  });
+});
+```
+
+- [ ] **Step 2 — run, expect fail:** `npx vitest run web/src/stores/scope.test.ts` → module missing.
+      (Note: the repo's vitest runs from root; this test lives under web/. If the root vitest config doesn't include web/src, run it via the web workspace: `cd web && npx vitest run src/stores/scope.test.ts`. Use whichever picks it up; confirm it FAILS first.)
+
+- [ ] **Step 3 — implement the helper** (code above).
+
+- [ ] **Step 4 — add scope state to `web/src/stores/player.ts`:**
+  - state: `scopedBotId: null as string | null`.
+  - getter: `isScoped: (state) => state.scopedBotId !== null`.
+  - actions:
+    - `setScope(id: string)` → `this.scopedBotId = id;` and also set `this.activeBotId = id` (scoped == active), then ensure that bot's queue is loaded like `setActiveBotId` does.
+    - `clearScope()` → `this.scopedBotId = null;`.
+    - `applyScopeFromQuery(requestedId: string | null)` → uses `resolveScopedBot(requestedId, this.bots.map(b => b.id))`; if result non-null → `setScope(result)`; if null and a scope was requested → `clearScope()`. (Called after bots are loaded.)
+  - Guard `setActiveBotId(id)`: at the top, `if (this.scopedBotId !== null && id !== this.scopedBotId) return;` so switching is blocked while scoped.
+
+- [ ] **Step 5 — run helper test, expect pass:** `cd web && npx vitest run src/stores/scope.test.ts` → 3 pass. `cd web && npx vue-tsc --noEmit` → exit 0.
+
+- [ ] **Step 6 — commit:** `git add web/src/stores/scope.ts web/src/stores/scope.test.ts web/src/stores/player.ts && git commit -m "feat(scope): player store scopedBotId + resolveScopedBot helper"`
+
+---
+
+## Task 2: Router guard — sync scope from `?bot` + preserve across navigation
+
+**Files:** Modify `web/src/router/index.ts`.
+
+READ the file: the existing `beforeEach` (~lines 36-60) handles needsSetup/auth. Add scope handling AFTER auth resolves (so we don't fight the login redirect). Import the player store (use it inside the guard via `usePlayerStore()` — Pinia is active by the time navigation runs).
+
+- [ ] **Step 1 — implement.** In `beforeEach`, after the existing auth/needsSetup logic decides the navigation is allowed to proceed to `to` (i.e., not redirecting to /login or /first-run), add:
+
+```typescript
+const store = usePlayerStore();
+const qBot = typeof to.query.bot === "string" ? to.query.bot : null;
+if (qBot) {
+  // entering/with a scope in the URL — store will validate against bots later
+  store.scopedBotId = qBot;        // tentative; applyScopeFromQuery (after fetchBots) confirms/clears
+  return next();
+}
+if (store.scopedBotId) {
+  // scoped but this navigation dropped ?bot → re-attach so the lock survives in-app nav + refresh
+  if (to.query.bot !== store.scopedBotId) {
+    return next({ ...to, query: { ...to.query, bot: store.scopedBotId } });
+  }
+}
+return next();
+```
+
+(Adapt to the file's existing `next()` style — it may use `next(...)`/return. Ensure this runs only for allowed navigations, not when redirecting to /login. The exit action in Task 4 calls `store.clearScope()` BEFORE navigating to `/`, so `store.scopedBotId` is null and the re-attach branch is skipped — that's how exit works.)
+
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0. Re-read the guard to ensure no redirect loop (when `to.query.bot === store.scopedBotId`, it does NOT redirect again).
+
+- [ ] **Step 3 — commit:** `git add web/src/router/index.ts && git commit -m "feat(scope): router guard syncs + preserves ?bot across navigation"`
+
+---
+
+## Task 3: BotRedirect seeds the URL scope
+
+**Files:** Modify `web/src/views/BotRedirect.vue`.
+
+READ it: onMounted reads `route.params.id`, ensures `store.fetchBots()`, finds the bot; if found `store.setActiveBotId(id)` + `router.replace('/')`; else shows not-found.
+
+- [ ] **Step 1 — implement.** Change the found-branch to seed scope via the URL instead of bouncing to a bare `/`:
+  - keep the fetchBots + existence check,
+  - if found: `router.replace({ path: '/', query: { bot: botId } })` (the router guard + store will set the scope). Optionally also call `store.setScope(botId)` directly for immediacy.
+  - if not found: unchanged (show "机器人不存在或未加载").
+
+- [ ] **Step 2 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0.
+- [ ] **Step 3 — commit:** `git add web/src/views/BotRedirect.vue && git commit -m "feat(scope): dedicated link seeds ?bot scope instead of bare redirect"`
+
+---
+
+## Task 4: Navbar lock UI + apply-scope-on-load
+
+**Files:** Modify `web/src/components/Navbar.vue`, `web/src/App.vue`.
+
+READ both: Navbar has `controllableBots` (computed) + the dropdown selector + `selectBot`; App.vue onMounted calls `playerStore.fetchBots()` (+ loadTheme/connect).
+
+- [ ] **Step 1 — Navbar lock.** When `store.isScoped`:
+  - render only the scoped bot (a `displayedBots` computed → if scoped, `controllableBots.filter(b => b.id === store.scopedBotId)`, else `controllableBots`),
+  - disable the dropdown open / switching (no chevron, or make the trigger non-interactive) so the user can't switch,
+  - hide other bots' "copy link" affordances (only the scoped bot remains anyway),
+  - show a small "专属模式" badge and an "退出" button → `store.clearScope(); router.push('/')` (clear BEFORE navigating so the guard doesn't re-attach `?bot`). Import `useRouter` if not present.
+  When not scoped: behavior unchanged.
+
+- [ ] **Step 2 — apply scope on load (App.vue).** After `fetchBots()` resolves in onMounted, call `playerStore.applyScopeFromQuery(routeBot)` where `routeBot` is the current `?bot` query (via `useRoute().query.bot` as string|null). This confirms a refreshed `?bot` against the loaded bots and sets activeBotId (or gracefully clears if the bot is gone). (If Task 2's guard already set `scopedBotId` tentatively, this validates it against the now-loaded bot list.)
+
+- [ ] **Step 3 — verify:** `cd web && npx vue-tsc --noEmit` → exit 0. Read templates back for valid syntax; confirm read-only displays aren't broken and the non-scoped path is unchanged.
+- [ ] **Step 4 — commit:** `git add web/src/components/Navbar.vue web/src/App.vue && git commit -m "feat(scope): lock Navbar selector to scoped bot + apply scope on load"`
+
+---
+
+## Final verification
+- [ ] `cd web && npx vue-tsc --noEmit` → exit 0
+- [ ] `npx tsc --noEmit` → exit 0 (backend unaffected)
+- [ ] `cd web && npx vitest run src/stores/scope.test.ts` (or root vitest if it includes web) → pass
+- [ ] `npm run build` → succeeds
+- [ ] Manual: open `/bot/<id>` → URL becomes `/?bot=<id>`, selector shows only that bot, switching disabled; **refresh → still locked** (item 4 fixed); navigate to Search → URL keeps `?bot`; refresh on Search → still locked; click 退出 → back to all bots (`/`, no `?bot`); open `/` directly → full multi-bot control; open `/?bot=<nonexistent>` → gracefully shows all bots (no lock).
+
+## Notes
+- Backend per-bot authorization (PR #80) is the real security boundary; this is a UX lock.
+- No localStorage — URL is the source of truth, so the lock is shareable and self-clearing.
+- Item 4 is fixed as a consequence of carrying `?bot` in the URL across refresh/navigation.

+# TeamSpeak chat-command permission control — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Gate a fixed set of "admin" TeamSpeak chat commands (`stop`, `clear`, `remove`, `move`, `vol`, `mode`) behind configured TS server-group IDs, opt-in and backward-compatible, configurable from the WebUI and `config.json`.
+
+**Architecture:** A pure helper `canRunCommand(name, invokerGroups, adminGroups)` decides allow/deny. The chat handler `handleTextMessage` (NOT the WebUI-shared `executeCommand`) consults it before executing, performs a best-effort group lookup when the sender's groups weren't delivered with the event, fails closed, and replies on deny. The privileged groups live in the already-declared `config.adminGroups`, surfaced through the existing `GET/POST /api/bot/settings` endpoints and an admin-only Settings.vue section.
+
+**Tech Stack:** Node 20, TypeScript (ESM), Express 5, Vitest + supertest (backend), Vue 3 + `vue-tsc` (frontend), `@honeybbq/teamspeak-client`.
+
+## Global Constraints
+
+- **ESM import specifiers:** every relative import ends in `.js` even in `.ts` files (e.g. `import { canRunCommand } from "./commands.js"`).
+- **Admin command set (exact, single source of truth):** `stop`, `clear`, `remove`, `move`, `vol`, `mode`. Everything else is public. (Note: `follow` is intentionally NOT admin — it becomes public.)
+- **Enforcement is opt-in / backward-compatible:** `config.adminGroups === []` (the default) ⇒ no enforcement; admin commands stay open to everyone exactly as today.
+- **Fail closed:** an admin command, with enforcement on, whose sender groups cannot be determined (even after fallback) is **denied**.
+- **Group-id normalization:** `invokerGroups` are strings, `adminGroups` are numbers — compare as the same type so `"6"` matches `6`.
+- **Denial reply text (exact):** `⛔ 需要管理员权限（该命令仅限管理员服务器组）`.
+- **`adminGroups` validation:** array of non-negative integers; filter out everything else; ignore a non-array value entirely.
+- **Live config:** `BotInstance` shares the same `config` object the router mutates; the gate reads `this.config.adminGroups` live (no restart, no propagation call).
+- **Per-task tests:** run `npx vitest run <file>` (targets `.ts` directly). Before any full `npm test`, run `rm -rf dist` first — a stale untracked `dist/` makes vitest double-run compiled `.test.js` copies (known environment quirk). The repo path contains spaces (`/c/Users/saopig1/Music/teamspeak music bot`) — quote it.
+- **Frontend type-check:** `cd web && npx vue-tsc --noEmit` (must be clean).
+- **TDD + frequent commits:** every task is red→green→commit. Keep project `tsc`/`vitest` green after each task.
+
+---
+
+### Task 1: `canRunCommand` helper + admin-set as single source of truth
+
+**Files:**
+- Modify: `src/bot/commands.ts` (lines 8-16 sets; line 59-61 `isAdminCommand`)
+- Test: `src/bot/commands.test.ts` (append a new `describe` block)
+
+**Interfaces:**
+- Consumes: nothing from other tasks.
+- Produces:
+  - `export const ADMIN_COMMANDS: Set<string>` = `{stop, clear, remove, move, vol, mode}`
+  - `export function isAdminCommand(commandName: string): boolean` (unchanged signature)
+  - `export function canRunCommand(commandName: string, invokerGroups: readonly (string | number)[], adminGroups: readonly number[]): boolean` — consumed by Task 3.
+
+- [ ] **Step 1: Write the failing tests**
+
+Append to `src/bot/commands.test.ts`:
+
+```ts
+import { canRunCommand, isAdminCommand } from "./commands.js";
+
+describe("isAdminCommand classification", () => {
+  it("treats stop/clear/remove/move/vol/mode as admin", () => {

+    }
+  });
+  it("treats follow and play as NOT admin", () => {
+    expect(isAdminCommand("follow")).toBe(false);
+    expect(isAdminCommand("play")).toBe(false);
+  });
+});
+
+describe("canRunCommand", () => {
+  it("allows any public command regardless of groups", () => {
+    expect(canRunCommand("play", [], [6])).toBe(true);
+    expect(canRunCommand("follow", [], [6])).toBe(true);
+  });
+  it("allows admin command when enforcement is off (empty adminGroups)", () => {
+    expect(canRunCommand("stop", [], [])).toBe(true);
+  });
+  it("allows admin command when an invoker group matches (string vs number)", () => {

+  });
+  it("denies admin command when no invoker group matches", () => {
+    expect(canRunCommand("stop", ["8"], [6])).toBe(false);

+- [ ] **Step 2: Run the tests to verify they fail**
+
+Run: `npx vitest run "src/bot/commands.test.ts"`
+Expected: FAIL — `canRunCommand` is not exported / not a function.
+
+- [ ] **Step 3: Implement the helper and tighten the admin set**
+
+In `src/bot/commands.ts`, delete the dead `PUBLIC_COMMANDS` export (nothing imports it; the admin set is the sole source of truth), set `ADMIN_COMMANDS` to the exact spec set (drop `follow`), and add `canRunCommand`. The file becomes:
+
+```ts
+export interface ParsedCommand {
+  name: string;
+  args: string;
+  rawArgs: string[];
+  flags: Set<string>;
+}
+
+/**
+ * The fixed set of "admin" chat commands. This is the SINGLE source of truth
+ * for which commands the permission gate restricts; reclassifying a command is
+ * a one-line edit here. Everything not in this set is public.

+export const ADMIN_COMMANDS = new Set([
+  "stop", "clear", "remove", "move", "vol", "mode",
+]);
+
+export function parseCommand(

+  const flags = new Set<string>();
+  const argParts: string[] = [];
+
+  for (let i = 1; i < parts.length; i++) {

+export function canRunCommand(

+  const admin = new Set(adminGroups.map((g) => String(g)));
+  return invokerGroups.some((g) => admin.has(String(g)));
+}
+```
+
+- [ ] **Step 4: Run the tests to verify they pass**
+
+Run: `npx vitest run "src/bot/commands.test.ts"`
+Expected: PASS (parser tests + the new classification/canRunCommand tests).
+
+- [ ] **Step 5: Verify nothing else imported the deleted symbol**
+
+Run: `grep -rn "PUBLIC_COMMANDS" src/`
+Expected: no matches (confirms the deletion is safe).

+
+### Task 2: Surface `invokerGroups` on `TS3TextMessage`
+
+**Files:**
+- Modify: `src/ts-protocol/client.ts` (interface lines 58-64; mapping lines 205-214)
+- Test: `src/ts-protocol/text-message.test.ts` (new)
+
+**Interfaces:**
+- Consumes: nothing from other tasks.
+- Produces:
+  - `TS3TextMessage` gains `invokerGroups: string[]`.
+  - `export function toTS3TextMessage(msg: TextMessage): TS3TextMessage` — a pure mapper, used by the `textMessage` event handler and unit-testable. Consumed (the field) by Task 3.
+
+- [ ] **Step 1: Write the failing test**
+
+Create `src/ts-protocol/text-message.test.ts`:
+
+```ts
+import { describe, it, expect } from "vitest";
+import { toTS3TextMessage } from "./client.js";
+import type { TextMessage } from "@honeybbq/teamspeak-client";
+
+function makeMsg(over: Partial<TextMessage> = {}): TextMessage {

+    const partial = {
+      invokerName: "Bob",
+      invokerUID: "u",
+      message: "!stop",
+      targetMode: 1,
+      targetID: 0n,
+      invokerID: 7,
+    } as unknown as TextMessage;
+    expect(toTS3TextMessage(partial).invokerGroups).toEqual([]);
+  });
+});
+```
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run: `npx vitest run "src/ts-protocol/text-message.test.ts"`
+Expected: FAIL — `toTS3TextMessage` is not exported.
+
+- [ ] **Step 3: Add the field and the pure mapper, and use it in the handler**
+
+In `src/ts-protocol/client.ts`, extend the interface (add `invokerGroups`):
+
+```ts
+export interface TS3TextMessage {
+  invokerName: string;
+  invokerId: string;
+  invokerUid: string;
+  message: string;
+  targetMode: number; // 1=private, 2=channel, 3=server
+  invokerGroups: string[]; // sender's TS server-group ids; [] when not in view cache
+}
+```
+
+Add the pure mapper just below the interface (still above the `TS3Client` class):
+
+```ts
+/**
+ * Map the library's TextMessage to our wrapper. Preserves invokerGroups (the
+ * sender's TS server groups), which the library populates only when the sender
+ * is in the bot's client-view cache; otherwise it is []. Used by the chat
+ * command permission gate.
+ */
+export function toTS3TextMessage(msg: TextMessage): TS3TextMessage {
+  return {
+    invokerName: msg.invokerName,
+    invokerId: String(msg.invokerID),
+    invokerUid: msg.invokerUID,
+    message: msg.message,
+    targetMode: msg.targetMode,
+    invokerGroups: msg.invokerGroups ?? [],
+  };
+}
+```
+
+Replace the inline mapping inside `this.client.on("textMessage", ...)` (currently lines 205-214) with a call to the mapper:
+
+```ts
+    this.client.on("textMessage", (msg: TextMessage) => {
+      this.emit("textMessage", toTS3TextMessage(msg));
+    });
+```
+
+(`TextMessage` is already imported at the top of the file.)
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run: `npx vitest run "src/ts-protocol/text-message.test.ts"`
+Expected: PASS (3 tests).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add "src/ts-protocol/client.ts" "src/ts-protocol/text-message.test.ts"
+git commit -m "feat(ts-protocol): surface invokerGroups on TS3TextMessage via pure mapper"
+```
+
+---
+
+### Task 3: Permission gate in `handleTextMessage` (fallback lookup + fail-closed + denial reply)
+
+**Files:**
+- Modify: `src/bot/instance.ts` (imports lines 10-14; add a module constant; `handleTextMessage` lines 317-349; add two private methods)
+- Test: `src/bot/instance.test.ts` (append a new `describe` block)
+
+**Interfaces:**
+- Consumes:
+  - `canRunCommand(commandName, invokerGroups, adminGroups)` from `./commands.js` (Task 1).
+  - `TS3TextMessage.invokerGroups: string[]` (Task 2).
+  - Existing `this.tsClient.getClientsInChannel(): Promise<ClientInfo[]>` where each `ClientInfo` has `id: number` and `serverGroups: string[]` (library already parses these).
+  - Existing `this.tsClient.sendTextMessage(message: string, targetMode?: number): Promise<void>`.
+- Produces:
+  - `export const COMMAND_DENIED_MESSAGE: string` (exported so the test can assert it).

+/** Reply sent when a non-admin invokes an admin-only chat command. */
+export const COMMAND_DENIED_MESSAGE = "⛔ 需要管理员权限（该命令仅限管理员服务器组）";

+
+Replace `handleTextMessage` (lines 317-349) so the dead stub becomes the real gate:

+- [ ] **Step 4: Run the gate tests to verify they pass**
+
+Run: `npx vitest run "src/bot/instance.test.ts"`
+Expected: PASS (existing `runExclusive` tests + the 7 new gate tests).
+
+- [ ] **Step 5: Confirm the live-config invariant**
+
+Confirm `BotInstance` reads `adminGroups` from the shared, mutable config — not a copy. The constructor stores `this.config = options.config` (line 91 region) and the router (`src/web/api/bot.ts`) mutates that same object; no propagation call is needed. Quick check:
+
+Run: `grep -n "this.config = options.config\|this.config.adminGroups" "src/bot/instance.ts"`
+Expected: shows the assignment and the gate read (proves the gate uses the live reference).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add "src/bot/instance.ts" "src/bot/instance.test.ts"
+git commit -m "feat(bot): gate admin chat commands on adminGroups with fallback + deny reply"
+```
+
+---
+
+### Task 4: Read/write `adminGroups` in the settings endpoints
+
+**Files:**
+- Modify: `src/web/api/bot.ts` (GET `/settings` lines 35-41; POST `/settings` lines 45-97)
+- Test: `src/web/api/bot.test.ts` (append `it` cases to the first `describe("bot router /settings", …)` block)
+
+**Interfaces:**
+- Consumes: existing `config.adminGroups: number[]` (already declared in `src/data/config.ts`, default `[]`).
+- Produces: `GET /api/bot/settings` returns `adminGroups: number[]`; `POST /api/bot/settings` accepts, validates, persists, and echoes `adminGroups`.
+
+- [ ] **Step 1: Write the failing tests**
+
+Append these `it` cases inside the existing first `describe("bot router /settings", …)` block in `src/web/api/bot.test.ts` (it already wires `app`, `config`, and an admin `cookie`):
+
+```ts
+  it("GET /settings includes adminGroups reflecting config", async () => {
+    config.adminGroups = [6, 8];
+    const res = await request(app).get("/api/bot/settings").set("Cookie", cookie);
+    expect(res.status).toBe(200);
+    expect(res.body.adminGroups).toEqual([6, 8]);
+  });
+
+  it("POST /settings persists a validated adminGroups and GET returns it", async () => {
+    const res = await request(app)
+      .post("/api/bot/settings")
+      .set("Cookie", cookie)
+      .send({ adminGroups: [6, 8] });
+    expect(res.status).toBe(200);
+    expect(res.body.adminGroups).toEqual([6, 8]);
+    expect(config.adminGroups).toEqual([6, 8]);
+    const followUp = await request(app).get("/api/bot/settings").set("Cookie", cookie);
+    expect(followUp.body.adminGroups).toEqual([6, 8]);
+  });
+
+  it("POST /settings filters invalid adminGroups entries (negative, non-integer, non-number)", async () => {
+    const res = await request(app)
+      .post("/api/bot/settings")
+      .set("Cookie", cookie)
+      .send({ adminGroups: [6, -1, 2.5, "x", 8] });
+    expect(res.status).toBe(200);
+    expect(config.adminGroups).toEqual([6, 8]);
+  });
+
+  it("POST /settings ignores a non-array adminGroups (leaves config unchanged)", async () => {

+      .set("Cookie", cookie)
+      .send({ adminGroups: "6" });
+    expect(res.status).toBe(200);
+    expect(config.adminGroups).toEqual([6]);
+  });
+```
+
+- [ ] **Step 2: Run the tests to verify they fail**
+
+Run: `npx vitest run "src/web/api/bot.test.ts"`
+Expected: FAIL — `res.body.adminGroups` is `undefined`; the POST does not persist `adminGroups`.
+
+- [ ] **Step 3: Extend the GET handler**
+
+In `src/web/api/bot.ts`, add `adminGroups` to the GET `/settings` response (the handler at lines 35-41):
+
+```ts
+  router.get("/settings", requireNotGuest, (_req, res) => {
+    res.json({
+      idleTimeoutMinutes: config.idleTimeoutMinutes ?? 0,
+      autoPauseOnEmpty: config.autoPauseOnEmpty,
+      adminGroups: config.adminGroups ?? [],
+      guestMode: config.guestMode,
+    });
+  });
+```
+
+- [ ] **Step 4: Extend the POST handler**
+
+In the POST `/settings` handler: (a) pull `adminGroups` out of `req.body`; (b) validate + assign before `saveConfig`; (c) echo it in the response. Change the destructuring line (46):
+
+```ts
+    const { idleTimeoutMinutes, autoPauseOnEmpty, guestMode, adminGroups } = req.body;
+```
+
+Add this block just before `saveConfig(configPath, config);` (line 77):
+
+```ts
+    if (Array.isArray(adminGroups)) {
+      config.adminGroups = adminGroups.filter(
+        (g: unknown): g is number =>
+          typeof g === "number" && Number.isInteger(g) && g >= 0,
+      );
+    }
+```
+
+Add `adminGroups` to BOTH `res.json({ … })` bodies in this handler (the success response near line 92, and — if present — keep them consistent):
+
+```ts
+    res.json({
+      idleTimeoutMinutes: config.idleTimeoutMinutes ?? 0,
+      autoPauseOnEmpty: config.autoPauseOnEmpty,
+      adminGroups: config.adminGroups ?? [],
+      guestMode: config.guestMode,
+    });
+```
+
+- [ ] **Step 5: Run the tests to verify they pass**
+
+Run: `npx vitest run "src/web/api/bot.test.ts"`
+Expected: PASS (existing settings/guest-mode tests + the 4 new adminGroups tests).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add "src/web/api/bot.ts" "src/web/api/bot.test.ts"
+git commit -m "feat(api): read/write adminGroups in bot settings endpoints"
+```
+
+---
+
+### Task 5: Admin-only "命令权限" section in Settings.vue
+
+**Files:**
+- Modify: `web/src/views/Settings.vue` (template: add a section after the Guest Mode section, before the Bot Profile section ~line 506; script: add state + handlers near the guest-mode block ~line 1093; hydrate in `loadIdleTimeout` ~line 1024)
+
+**Interfaces:**
+- Consumes: `GET /api/bot/settings` → `adminGroups: number[]`; `POST /api/bot/settings` with `{ adminGroups: number[] }` (Task 4). Existing `session.isAdmin.value`.
+- Produces: UI only.
+
+- [ ] **Step 1: Add the template section**
+
+In `web/src/views/Settings.vue`, insert this `<section>` immediately AFTER the closing `</section>` of the Guest Mode block (the one whose title is `游客模式`, ends ~line 505) and BEFORE the `<!-- Bot Profile … -->` section:
+
+```html
+    <!-- Command Permissions (admin only) -->
+    <section v-if="session.isAdmin.value" class="settings-section">
+      <h2 class="section-title">命令权限</h2>
+      <p class="profile-section-hint">
+        限制谁能在 TeamSpeak 聊天里运行管理类命令（stop / clear / remove / move / vol / mode）。
+        填写允许的服务器组 ID（逗号分隔）。留空 = 不限制，所有人可用。如何查看服务器组 ID 见 README。
+      </p>
+      <div class="setting-row">
+        <div class="prefix-input-wrap">
+          <input v-model="adminGroupsText" class="input input-sm" placeholder="如 6, 8" />
+          <button class="btn-primary" :disabled="adminGroupsSaving" @click="saveAdminGroups">
+            {{ adminGroupsSaving ? '保存中…' : '保存' }}
+          </button>
+        </div>
+      </div>
+    </section>
+```
+
+- [ ] **Step 2: Add the script state + handlers**
+
+In the `<script setup>` block, add this just after the guest-mode block (after `saveGuestMode` closes, ~line 1093):
+
+```ts
+// --- Command permissions (admin only) ---
+const adminGroupsText = ref('');
+const adminGroupsSaving = ref(false);
+
+function applyAdminGroupsFromServer(groups: unknown) {
+  if (Array.isArray(groups)) {
+    adminGroupsText.value = groups.filter((g) => typeof g === 'number').join(', ');
+  }
+}
+
+function parseAdminGroups(text: string): number[] {
+  return text
+    .split(',')
+    .map((s) => s.trim())
+    .filter((s) => s.length > 0)
+    .map((s) => Number(s))
+    .filter((n) => Number.isInteger(n) && n >= 0);
+}
+
+async function saveAdminGroups() {
+  adminGroupsSaving.value = true;
+  try {
+    const res = await axios.post('/api/bot/settings', { adminGroups: parseAdminGroups(adminGroupsText.value) });
+    applyAdminGroupsFromServer(res.data?.adminGroups);
+  } catch { /* ignore */ } finally {
+    adminGroupsSaving.value = false;
+  }
+}
+```
+
+- [ ] **Step 3: Hydrate on load**
+
+In `loadIdleTimeout` (the existing function ~lines 1024-1031), add the hydrate call alongside `applyGuestModeFromServer`:
+
+```ts
+async function loadIdleTimeout() {
+  try {
+    const res = await axios.get('/api/bot/settings');
+    idleTimeout.value = res.data.idleTimeoutMinutes ?? 0;
+    autoPauseOnEmpty.value = res.data.autoPauseOnEmpty ?? false;
+    applyGuestModeFromServer(res.data.guestMode);
+    applyAdminGroupsFromServer(res.data.adminGroups);
+  } catch { /* ignore */ }
+}
+```
+
+- [ ] **Step 4: Type-check the frontend**
+
+Run: `cd "web" && npx vue-tsc --noEmit`
+Expected: no errors.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add "web/src/views/Settings.vue"
+git commit -m "feat(web): admin-only command-permission (adminGroups) settings section"
+```
+
+---
+
+### Task 6: Document the feature in the README
+
+**Files:**
+- Modify: `README.md`
+
+**Interfaces:**
+- Consumes: nothing (docs).
+- Produces: user-facing documentation of the feature + how to find TS server-group IDs.
+
+- [ ] **Step 1: Locate the insertion point**
+
+Run: `grep -n "游客模式\|Guest\|权限\|adminGroups" "README.md"`
+Expected: shows the guest-mode / permissions area. Insert the new subsection immediately after the guest-mode documentation block (or, if there is a dedicated permissions/features section, at its end).
+
+- [ ] **Step 2: Add the documentation block**
+
+Insert this markdown at the chosen point:
+
+```markdown
+### TeamSpeak 命令权限（管理类命令限制）
+
+默认情况下，频道里任何人都能运行所有聊天命令。你可以把一组「管理类」命令限制为只有特定 TeamSpeak 服务器组的成员才能运行：
+
+- 受限命令：`stop`、`clear`、`remove`、`move`、`vol`、`mode`
+- 其余命令（点歌、队列、跳过、歌词等）始终对所有人开放
+- **默认不限制**：管理服务器组列表为空时，所有命令对所有人开放（向后兼容）
+
+**配置方式**
+
+- 网页端：设置 → 命令权限，填写允许的服务器组 ID（逗号分隔），保存即时生效。
+- 或编辑 `config.json` 的 `adminGroups`（数字数组），例如 `"adminGroups": [6, 8]`。
+
+填入任意服务器组 ID 后，限制立即开启：只有属于这些组之一的用户才能运行受限命令，其他人会收到「⛔ 需要管理员权限」的提示。
+
+> 提示（fail-closed）：当受限命令来自一个机器人当前看不到其服务器组的发送者（例如不在机器人所在频道的私聊），机器人会尝试查询其分组；若仍无法确定，则拒绝执行。
+
+**如何查看服务器组 ID**
+
+在 TeamSpeak 客户端中打开「权限 → 服务器组」（Permissions → Server Groups）对话框，选中某个组后，其 ID 会显示在标题栏/状态栏；或在服务器组管理界面中查看每个组对应的数字 ID。把需要授权的组 ID 填入上面的设置即可。
+```
+
+- [ ] **Step 3: Sanity-check the docs render**
+
+Run: `grep -n "命令权限\|adminGroups" "README.md"`
+Expected: shows the newly added section.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add "README.md"
+git commit -m "docs: document TeamSpeak chat-command permission control"
+```
+
+---
+
+## Final verification (after all tasks)
+
+- [ ] Remove stale compiled output, then run the full suite:
+
+```bash
+rm -rf dist
+npm test
+```
+Expected: all tests pass (the new `canRunCommand`, `toTS3TextMessage`, gate, and `adminGroups` settings tests included).
+
+- [ ] Full build (backend `tsc` + frontend `vue-tsc` + vite):
+
+```bash
+npm run build
+```
+Expected: SUCCESS (no type errors).

+# Bot Profile Manager — Design Spec
+
+## Goal
+
+When the bot plays a song, automatically update its TeamSpeak presence (avatar, description, nickname, away status, channel description) and send a "now playing" chat message. When playback stops, restore all values to defaults. Each feature is independently configurable and permission-safe — if the bot lacks a required server permission, that feature silently disables itself until the next reconnect.
+
+## Features
+
+| # | Feature | Update on song | Restore on stop | TS3 mechanism | TS6 mechanism |
+|---|---------|---------------|-----------------|---------------|---------------|
+| 1 | Avatar | Album cover art | Delete avatar | File transfer upload + `clientupdate client_flag_avatar=<md5>` | Same (file transfer is protocol-level) |
+| 2 | Description | `歌名 - 歌手 [专辑]` | Clear (empty string) | `clientupdate client_description=...` | `httpQuery.clientUpdate(...)` |
+| 3 | Nickname | `♪ 歌名 - 歌手 \| 原昵称` (max 30 chars) | Restore `defaultNickname` | `clientupdate client_nickname=...` | `httpQuery.clientUpdate(...)` |
+| 4 | Away status | `client_away=1`, message = `正在播放: 歌名 - 歌手` | `client_away=0` | `clientupdate client_away=...` | `httpQuery.clientUpdate(...)` |
+| 5 | Channel description | `正在播放: 歌名 - 歌手\n专辑: xxx\n平台: xxx` | Clear | `channeledit cid=... channel_description=...` | `httpQuery.request("POST", "/1/channeledit", ...)` |
+| 6 | Now-playing message | `♪ 正在播放: 歌名 - 歌手 [专辑]` | (not sent on stop) | `sendTextMessage` (existing) | `sendTextMessage` (existing) |
+
+## Architecture
+
+```
+resolveAndPlay() success / stop / clear / playNext exhausted
+    ↓
+BotInstance → BotProfileManager.onSongChange(song | null)
+                 ├─ updateAvatar(coverUrl | null)       [fire-and-forget]
+                 ├─ updateDescription(song | null)
+                 ├─ updateNickname(song | null)
+                 ├─ updateAwayStatus(song | null)
+                 ├─ updateChannelDescription(song | null)
+                 └─ sendNowPlayingMessage(song)          [only when song != null]
+
+BotInstance.connect()  → profileManager.onConnect()   // reset perm flags, restore defaults
+BotInstance.disconnect() → (no action needed, server cleans up)
+```
+
+## File Changes
+
+| File | Change |
+|------|--------|
+| `src/bot/profile.ts` | **New** — `BotProfileManager` class |
+| `src/ts-protocol/client.ts` | Add `execCommand`, `execCommandWithResponse`, file transfer methods, `escapeTS3()` |
+| `src/bot/instance.ts` | Create & hold `BotProfileManager`, call at lifecycle points |
+| `src/data/database.ts` | Add 6 profile config columns via ALTER TABLE migration |
+| `src/web/api/player.ts` | Add `GET/PUT /api/player/:botId/profile` endpoints |
+
+## TS3Client Layer Extensions
+
+New methods on `TS3Client` (all delegate to underlying `@honeybbq/teamspeak-client` Client):
+
+```typescript
+execCommand(cmd: string): Promise<void>
+execCommandWithResponse(cmd: string): Promise<Record<string, string>[]>
+fileTransferInitUpload(channelID: bigint, path: string, password: string,
+                       size: bigint, overwrite?: boolean): Promise<FileUploadInfo>
+uploadFileData(host: string, info: FileUploadInfo, data: Readable): Promise<void>
+fileTransferDeleteFile(channelID: bigint, paths: string[]): Promise<void>
+```
+
+Utility: `escapeTS3(str: string): string` — escapes spaces (`\s`), backslashes (`\\`), pipes (`\p`), slashes (`\/`).
+
+## BotProfileManager Detail
+
+```typescript
+interface ProfileConfig {
+  avatarEnabled: boolean;        // default true
+  descriptionEnabled: boolean;   // default true
+  nicknameEnabled: boolean;      // default true
+  awayStatusEnabled: boolean;    // default true
+  channelDescEnabled: boolean;   // default true
+  nowPlayingMsgEnabled: boolean; // default true
+}
+```
+
+### Permission Handling
+
+- Each feature has an independent `permDenied: boolean` flag.
+- On first failure where error message contains "permission" or "insufficient" → set flag, skip subsequent calls.
+- On `onConnect()` → reset all flags (new connection may have different permissions).
+- Non-permission errors (network timeout, etc.) do NOT set the flag — next song change will retry.
+
+### Nickname Truncation
+
+- Format: `♪ {songInfo} | {defaultNickname}`
+- TS3 max nickname: 30 characters
+- If total > 30: truncate songInfo, keep defaultNickname
+- If `♪  | {defaultNickname}` alone > 30: skip nickname update entirely
+
+### Avatar Upload Flow (TS3)
+
+1. Download cover image via axios (HTTP GET coverUrl) → Buffer
+2. `fileTransferInitUpload(0n, "/avatar", "", BigInt(buffer.length), true)`
+3. `uploadFileData(host, info, Readable.from(buffer))`
+4. Compute MD5: `crypto.createHash('md5').update(buffer).digest('hex')`
+5. `execCommand("clientupdate client_flag_avatar=" + md5)`
+
+To clear: `fileTransferDeleteFile(0n, ["/avatar"])` + `execCommand("clientupdate client_flag_avatar=")`
+
+### Fire-and-Forget
+
+Avatar download/upload is slow. `onSongChange()` launches all updates concurrently via `Promise.allSettled()` — failures are logged but never block playback.
+
+## Database Migration
+
+```sql
+ALTER TABLE bot_instances ADD COLUMN profile_avatar_enabled INTEGER DEFAULT 1;
+ALTER TABLE bot_instances ADD COLUMN profile_description_enabled INTEGER DEFAULT 1;
+ALTER TABLE bot_instances ADD COLUMN profile_nickname_enabled INTEGER DEFAULT 1;
+ALTER TABLE bot_instances ADD COLUMN profile_away_enabled INTEGER DEFAULT 1;
+ALTER TABLE bot_instances ADD COLUMN profile_channel_desc_enabled INTEGER DEFAULT 1;
+ALTER TABLE bot_instances ADD COLUMN profile_now_playing_enabled INTEGER DEFAULT 1;
+```
+
+## Web API
+
+```
+GET  /api/player/:botId/profile  → { avatarEnabled, descriptionEnabled, ... }
+PUT  /api/player/:botId/profile  → body: Partial<ProfileConfig> → 200 OK
+```
+
+## Constraints
+
+- All profile operations are async, never block playback
+- Uses existing `axios` dependency for image download
+- MD5 via Node.js built-in `crypto`
+- No new npm dependencies required

+# Design: FM Bug Fix + Artist Loop + Playlist Fuzzy Search
+
+Date: 2026-04-27
+
+## Overview
+
+Three features for the TeamSpeak Music Bot:
+1. New `!artist <name>` command — loop playback filtered by artist
+2. Fuzzy playlist name search in existing `!playlist` command
+3. Fix `!fm` audio dropout bug (no sound after a few songs but status shows playing)
+
+---
+
+## Feature 1: `!artist` Command
+
+### Behavior
+
+`!artist <歌手名> [-q|-b|-y]` searches for songs by the artist, loads them into the queue, sets the queue mode to `Loop`, and starts playing.
+
+### Flow
+
+1. Parse command with optional platform flags (`-q`, `-b`, `-y`)
+2. Call `provider.search(歌手名, 50)` to get up to 50 results
+3. Filter results: only keep songs where `song.artist` contains the search query (case-insensitive)
+4. If filtered list is empty, fall back to unfiltered search results (up to 20)
+5. Clear current queue, add filtered songs, set mode to `Loop`
+6. Play first song via `resolveAndPlay`
+
+### Key Decisions
+
+- **Why Loop mode?** The user said "循环播放" (loop playback). After the artist's songs are exhausted, they should restart.
+- **Why filter client-side?** The search API doesn't support artist-only filtering. We search broadly then narrow down.
+- **Why 50 results?** The default limit is 20, but for prolific artists we want more coverage. 50 balances API response size with coverage.
+
+### Files Changed
+
+- `src/bot/commands.ts`: Register `artist` in PUBLIC_COMMANDS, update help text
+- `src/bot/instance.ts`: New `cmdArtist()` method
+
+---
+
+## Feature 2: Playlist Fuzzy Search
+
+### Behavior
+
+`!playlist <name or ID>` now accepts both playlist IDs and playlist names. When the input is not a pure numeric ID, it searches for matching playlists and uses the top result.
+
+### Flow
+
+1. Parse input — if it's a pure numeric ID or contains a URL with an ID, use existing logic
+2. Otherwise, call `provider.search(input)` which already returns `playlists[]` in the result
+3. Also call `provider.getUserPlaylists()` if the provider supports it (logged-in state)
+4. Client-side fuzzy match user playlists: `playlist.name` contains input (case-insensitive)
+5. Merge results: public search results first (sorted by API relevance), then user matches
+6. Take the first playlist, load its songs, play
+
+### Key Decisions
+
+- **Why public search first?** It's already sorted by relevance from the API. User playlists are a secondary source.
+- **Why client-side matching for user playlists?** The `getUserPlaylists()` API returns all user playlists without a search parameter, so we must filter locally.
+- **Backward compatibility:** Numeric IDs and URL parsing are unchanged.
+
+### Files Changed
+
+- `src/bot/instance.ts`: Modify `cmdPlaylist()` to add search fallback
+- `src/bot/commands.ts`: Update help text
+
+---
+
+## Feature 3: FM Bug Fix
+
+### Root Cause Analysis
+
+The `!fm` bug manifests as: audio stops after a few songs, but `!now` shows a playing song and the song name keeps changing.
+
+`getPersonalFm()` returns only ~3 songs per API call. After those are consumed:
+- In `Sequential` mode: `queue.next()` returns null → `player.stop()` is called → playback stops entirely. This does NOT match "歌还在轮播" (songs still rotating).
+- In `Loop` mode (if user changed mode): the same 3 songs loop, but URLs may expire, causing silent playback failures.
+
+The most likely scenario for "no audio but status shows playing + song names changing":
+1. FM songs have URLs that resolve but don't produce playable audio (copyright/region restrictions)
+2. ffmpeg spawns, connects to the URL, gets an HTTP error or silent stream
+3. ffmpeg exits quickly (clean exit or error)
+4. The frame loop detects ffmpeg gone + buffer empty → emits `trackEnd`
+5. `playNext()` advances to the next song
+6. This rapid cycle (spawn → fail → advance) makes it appear that songs are "playing and rotating" but with no audio
+7. After 3 consecutive ffmpeg spawn failures, `consecutiveFailures >= MAX_CONSECUTIVE_FAILURES` → player refuses to spawn new ffmpeg processes
+8. After that, `resolveAndPlay` still sets state via `player.play()` which immediately emits "error" → `playNext()` skips to next → cycle continues with no ffmpeg at all
+
+### Fix Strategy
+
+**Fix 1 — FM auto-refill (primary fix):**
+- In `cmdFm()`, set queue mode to `RandomLoop` so the queue never "runs out"
+- Add a `refillFm()` method that fetches more FM songs and appends to queue
+- Hook into the `trackEnd` flow: when queue has ≤ 2 songs remaining and we're in FM mode, trigger a refill
+- Track FM state with a boolean flag `isFmMode` on the instance
+
+**Fix 2 — Reset consecutive failures on successful playback (safety net):**
+- Reset `consecutiveFailures` when a track plays successfully for at least N frames (e.g., 50 frames = 1 second)
+- This prevents transient URL failures from accumulating toward the hard limit
+
+**Fix 3 — FM refill before queue exhaustion:**
+- After `playNext()` successfully starts a song, check if `isFmMode` and `queue.size() - currentIndex <= 2`
+- If so, fire an async refill (don't block playback)
+
+### Files Changed
+
+- `src/bot/instance.ts`: Modify `cmdFm()`, add `refillFm()`, add FM state tracking, modify `playNext()` to check for FM refill
+- `src/audio/player.ts`: Add `framesPlayed` threshold check to reset `consecutiveFailures`
+
+---
+
+## Implementation Order
+
+1. **FM bug fix** first — it's a bug fix affecting current users
+2. **Playlist fuzzy search** — small change, quick win
+3. **Artist loop** — new feature, depends on queue/player being stable
+
+---
+
+## Testing
+
+- FM: Verify songs keep playing beyond the initial 3-song batch, verify auto-refill works
+- Playlist: Test with numeric ID (backward compat), test with playlist name (fuzzy search)
+- Artist: Test with known artist names, test edge case (no results), test with platform flags

+# Multi-Source Tabs for Recommend / User Playlists / Daily Songs
+
+**Date:** 2026-05-06
+**Status:** Spec — pending implementation
+
+## Problem
+
+Home 和 Library 页面的"推荐歌单 / 每日推荐 / 我的歌单"这三类内容当前硬编码只走网易云。当用户同时登录了网易云和 QQ 音乐时，无法在 Web UI 上看到 QQ 侧的对应内容、也无法切换查看。
+
+## Goal
+
+在以下 4 个 section 上提供"网易云 / QQ"来源切换 tab，桌面端和移动端均可用：
+
+- `Home.vue` — 推荐歌单
+- `Home.vue` — 每日推荐
+- `Home.vue` — 我的歌单
+- `Library.vue` — 我的歌单
+
+切换为纯前端动作（数据已预先 fetch），无加载闪烁。各 section 的选择独立持久化。
+
+## Out of Scope
+
+- 私人 FM（QQ 无对应概念）
+- B 站热门（独立第三来源，不属于网易/QQ 切换语义）
+- 最近播放（bot 维度的播放历史，与音乐源无关）
+- Library 现有的"我的收藏"段落 —— 当前调用的 `/api/music/user/liked` 端点不存在，是死代码，本次顺手移除
+- 登录状态实时同步（用户在 Settings 登录后需手动刷新 Home/Library 才能看到 QQ tab）
+- Tab 排序、隐藏、拖动等高级配置
+
+## Non-functional Constraints
+
+- 桌面端（>768px）和移动端（≤768px）布局均可用，tab 与 section title 同行排布；空间不足时允许 flex-wrap
+- Tab 触控区域有效高度 ≥36px
+- 现有 5 分钟 home data cache 行为保留
+- 不引入新的后端端点（后端已通过 `?platform=` 参数支持多源）
+
+## Architecture
+
+### 数据层（`web/src/stores/player.ts`）
+
+字段从单平台改为按 platform 切分：
+
+```ts
+// 前
+recommendPlaylists: PlaylistItem[]
+userPlaylists:      PlaylistItem[]
+dailySongs:         Song[]
+
+// 后
+recommendPlaylists: { netease: PlaylistItem[]; qq: PlaylistItem[] }
+userPlaylists:      { netease: PlaylistItem[]; qq: PlaylistItem[] }
+dailySongs:         { netease: Song[];         qq: Song[] }
+
+// 新增
+authStatus: { netease: boolean; qq: boolean }
+```
+
+`fetchHomeData()` 改写：
+
+1. 并发调用 `/api/auth/status?platform=netease` 与 `?platform=qq`，写入 `authStatus`
+2. 网易云的三类数据照常 fetch（推荐歌单匿名可访问；每日推荐和我的歌单需登录，未登录时 API 自然返回空或失败，`Promise.allSettled` 已隔离）
+3. QQ 的三类数据**仅在 QQ 登录时** fetch，未登录则为空数组
+4. B 站热门保持原样
+5. 5 分钟缓存 TTL 不变
+
+### UI 组件
+
+新增 `web/src/components/SourceTabs.vue`：
+
+```vue
+<SourceTabs v-model="activeSource" :sources="availableSources" />
+```
+
+Props：
+- `sources: ('netease' | 'qq')[]` — 由父组件根据 auth 状态过滤后传入
+- `modelValue: 'netease' | 'qq'` — v-model 绑定
+
+行为：
+- `sources.length < 2` 时组件**自身不渲染**（返回空），父组件无需 v-if 包装
+- 文字标签：`{ netease: '网易云', qq: 'QQ' }`
+- 视觉：水平排列，激活态用主色（`var(--color-primary)`）下划线 + 加粗，未激活态使用次要文字色
+- 紧贴 section-title 右侧，使用 `display: inline-flex`，移动端 padding/font-size 缩小
+
+### 各 section 接入模板
+
+```vue
+<section v-if="recommendAvailable.length > 0" class="section">
+  <h2 class="section-title">
+    推荐歌单
+    <SourceTabs v-model="recommendSource" :sources="recommendAvailable" />
+  </h2>
+  <div class="playlist-grid">
+    <RouterLink
+      v-for="pl in store.recommendPlaylists[recommendSource]"
+      :key="pl.id"
+      :to="`/playlist/${pl.id}?platform=${pl.platform}`"
+      class="playlist-card hover-scale"
+    >
+      <CoverArt :url="pl.coverUrl" :size="160" :radius="10" :show-shadow="true" />
+      <div class="playlist-name">{{ pl.name }}</div>
+    </RouterLink>
+  </div>
+</section>
+```
+
+每个 section 在 `<script setup>` 维护两个值：
+
+- `recommendSource: Ref<'netease' | 'qq'>` — 当前选中
+- `recommendAvailable: ComputedRef<('netease' | 'qq')[]>` — 该 section 在当前登录状态下有哪些 source 可选
+
+`recommendAvailable` 计算规则：
+
+| Section | netease 加入条件 | qq 加入条件 |
+|---|---|---|
+| Home 推荐歌单 | 总是（公开数据） | `authStatus.qq` |
+| Home 每日推荐 | `authStatus.netease` | `authStatus.qq` |
+| Home 我的歌单 | `authStatus.netease` | `authStatus.qq` |
+| Library 我的歌单 | `authStatus.netease` | `authStatus.qq` |
+
+#### "我的歌单"展开按钮兼容
+
+Home 的"我的歌单"现有 `USER_PLAYLIST_LIMIT = 20` 折叠/展开。改造后：
+
+```ts
+const visibleUserPlaylists = computed(() => {
+  const all = store.userPlaylists[userSource.value] ?? [];
+  return userPlaylistsExpanded.value ? all : all.slice(0, USER_PLAYLIST_LIMIT);
+});
+```
+
+切换 source 时折叠态保留（不需 reset）。
+
+### 持久化
+
+localStorage 键统一为一个 JSON：
+
+```
+key:   "source-tabs"
+value: {
+  "home.recommend": "qq",
+  "home.daily":     "netease",
+  "home.user":      "qq",
+  "library.user":   "netease"
+}
+```
+
+读：组件 mount 时一次性读 + 解析。
+写：在 v-model 的 setter 里 `watch` 一次写回。
+不存在的键 / 解析失败 / 老用户没这个 key —— 默认值 `"netease"`。
+
+### 边界与回退
+
+| 情况 | 行为 |
+|---|---|
+| 选的 source 不在 `available` 里（例：选了 QQ，登出后回到页面） | 渲染时 fallback 到 `available[0]`，不修改 localStorage（保留用户偏好，下次登回来仍生效） |
+| `recommendPlaylists.qq` 为空数组（API 失败 or 无数据） | tab 仍可切，切过去显示空 grid（无错误提示，符合现有"空数据隐藏 section"语义；section 顶层 v-if 检查的是 `available.length > 0`，单 platform 数据为空不影响 section 显隐） |
+| QQ provider 不支持 `getDailyRecommendSongs`（501） | `Promise.allSettled` 已捕获，`dailySongs.qq` 保持 `[]`，等同上一行 |
+| 用户在 Settings 登录 QQ 后切回 Home | 不自动 refetch / 不自动出 tab —— 用户需手动刷新页面（保留 5 分钟缓存语义） |
+| 网易云和 QQ 都没登录 | `available` 为空时 section 隐藏（沿用现有逻辑） |
+| Library "我的收藏" 段落 | 整段移除（含 template、script 中的 `liked` ref、对应 axios 调用） |
+
+## 修改文件清单
+
+新增：
+- `web/src/components/SourceTabs.vue` — 共享 tab 组件
+
+修改：
+- `web/src/stores/player.ts` — 多平台 state、`authStatus`、`fetchHomeData` 重写
+- `web/src/views/Home.vue` — 三个 section 接入 SourceTabs，对应 ref + computed
+- `web/src/views/Library.vue` — 我的歌单接入 SourceTabs；移除我的收藏死代码
+
+不改：
+- 后端（API 已支持 `?platform=`）
+- `Search.vue` / `Playlist.vue` / `Settings.vue` 等其他页面
+
+## 测试方案
+
+- 手动：在两种登录组合下访问 Home 和 Library，验证 tab 显隐、切换、刷新后持久化
+  - 仅网易登录 → 不显示 tab
+  - 两边登录 → 显示 tab，切换后刷新页面来源不变
+  - QQ 登录 → 网易登出 → 网易 tab 消失，若上次选的是网易则 fallback 到 QQ
+- 移动端（DevTools 768px 以下）：tab 与 section-title 同行不溢出，触控区域可点
+- TypeScript 类型检查通过：`npx tsc --noEmit` + `npm run build:web`
+- 单元测试：现有 vitest 套件不应回归（store 改动不破坏其他用法）
+
+## 风险
+
+- store 字段类型变更（数组 → 对象）会影响所有读取这三个字段的地方。需 grep 确认没有遗漏的消费者。
+- localStorage 解析失败的容错必须周全，避免一次脏数据导致整个页面白屏。

+# History-aware `prev` + "Play Next" Insert
+
+**Date:** 2026-05-06
+**Status:** Spec — pending implementation
+
+## Problem
+
+Two queue/playback gaps surfaced in real use:
+
+1. In `PlayMode.Random` and `PlayMode.RandomLoop`, `!prev` does not play the
+   actually-previously-played song. It just walks `currentIndex - 1` in the
+   underlying array — but in random modes `currentIndex` jumps non-sequentially,
+   so the "previous" array slot has no relationship to play history.
+
+2. `!add` / web "添加到队列" appends to the queue tail. There is no way to
+   say "play this song right after the current one." Users want a "下一首
+   播放" affordance comparable to Spotify "Add to Queue (next up)" or Apple
+   Music "Play Next".
+
+## Goals
+
+- `prev` walks back through the actual play history regardless of mode.
+- A new "Play Next" path inserts a song at `currentIndex + 1`, available
+  via web UI button and TS3 chat command.
+- Both features are usable on desktop and mobile web.
+
+## Out of Scope
+
+- Forward/redo through prev'd songs (user would need to push next manually,
+  which picks a fresh random in random modes — acceptable simplification).
+- Reordering songs already in the queue ("move to next" inside Queue.vue).
+- Persisting play history across bot restarts (in-memory only).
+
+## Non-functional Constraints
+
+- History capped at 50 entries to bound memory.
+- `addNext` must keep `playedIndices` and `history` index references valid
+  after insertion (shift all indices > current by +1).
+- New Toast UX from the previous round still applies (failures surface).
+- TypeScript and existing test suite must not regress.
+
+## Architecture
+
+### A. History-aware `prev`
+
+**`src/audio/queue.ts`** — `PlayQueue` gains a back-stack:
+
+```ts
+private history: number[] = [];
+private static readonly HISTORY_LIMIT = 50;
+
+private pushHistory(idx: number): void {
+  if (idx < 0) return;
+  this.history.push(idx);
+  if (this.history.length > PlayQueue.HISTORY_LIMIT) {
+    this.history.shift();
+  }
+}
+```
+
+Mutators call `pushHistory(this.currentIndex)` **before** changing `currentIndex`:
+
+| Method | History action |
+|---|---|
+| `play()` | `this.history = []` (fresh playback) |
+| `playAt(idx)` | `pushHistory(currentIndex)`, then set `currentIndex = idx` |
+| `next()` | `pushHistory(currentIndex)`, then advance per mode |
+| `prev()` | **Pop** from history → `currentIndex = popped`. If empty, fall back to existing `currentIndex - 1` (which keeps Sequential's wrap behavior; Random returns null). `prev` itself does NOT push to history. |
+| `clear()` | `this.history = []` |
+| `setMode(m)` | `this.history = []` (mode change resets context) |
+| `remove(idx)` | Drop matching entries from history; shift any entry `> idx` by `-1`. Same logic as the existing `playedIndices` rebuild. |
+
+**`prev()` rewrite:**
+
+```ts
+prev(): QueuedSong | null {
+  if (this.songs.length === 0) return null;
+  // History-driven path (preferred when we have one)
+  while (this.history.length > 0) {
+    const idx = this.history.pop()!;
+    if (idx >= 0 && idx < this.songs.length) {
+      this.currentIndex = idx;
+      this.playedIndices.add(idx);
+      return this.songs[idx];
+    }
+    // popped index is stale (song removed) — keep popping
+  }
+  // Fallback: old index-based prev
+  const prevIndex = this.currentIndex - 1;
+  if (prevIndex < 0) {
+    if (this.mode === PlayMode.Sequential) return null;
+    this.currentIndex = this.songs.length - 1;
+  } else {
+    this.currentIndex = prevIndex;
+  }
+  this.playedIndices.add(this.currentIndex);
+  return this.songs[this.currentIndex];
+}
+```
+
+### B. Play Next (insert after current)
+
+**`PlayQueue.addNext(song)`:**
+
+```ts
+addNext(song: QueuedSong): void {
+  if (this.currentIndex < 0 || this.songs.length === 0) {
+    this.songs.push(song);
+    return;
+  }
+  const insertAt = this.currentIndex + 1;
+  this.songs.splice(insertAt, 0, song);
+  // Shift any tracked index > currentIndex by +1
+  const shifted = new Set<number>();
+  for (const i of this.playedIndices) {
+    shifted.add(i > this.currentIndex ? i + 1 : i);
+  }
+  this.playedIndices = shifted;
+  this.history = this.history.map((i) => (i > this.currentIndex ? i + 1 : i));
+}
+```
+
+**Backend endpoint** — `src/web/api/player.ts`:
+
+```
+POST /api/player/:botId/play-next-song
+body: { song: Song }
+```
+
+Behavior:
+- If queue is empty or `currentIndex < 0`: `queue.addNext(song)` (which falls
+  through to plain push), then `queue.play()`, then `resolveAndPlay`. Same
+  semantics as a successful `/play-song` — message: "正在播放：…"
+- Otherwise: `queue.addNext(song)`, no resolveAndPlay. Message: "已加入下一首：…"
+- Returns `{ ok: boolean, message: string }` matching the convention
+  established in the previous round.
+
+**Bot command** — `src/bot/instance.ts`:
+
+Register `!playnext <query>` (alias `!pn`):
+- Mirror of `cmdPlay`'s search step
+- On match: `queue.addNext(song)`. If no current playback, fall through to
+  `resolveAndPlay`.
+- Reply with `已加入下一首：<name>` or `正在播放：<name>` accordingly
+
+**Frontend store action** — `web/src/stores/player.ts`:
+
+```ts
+async playNextSong(song: Song) {
+  if (!this.activeBotId) return;
+  const res = await axios.post(`/api/player/${this.activeBotId}/play-next-song`, { song });
+  if (res.data?.message) {
+    this.notify(res.data.message, res.data.ok === false ? 'error' : 'info');
+  }
+}
+```
+
+**Frontend SongCard** — `web/src/components/SongCard.vue`:
+
+Add a third action button between the existing "play" and "add to queue":
+
+```vue
+<button class="action-btn" @click.stop="$emit('playNext')" title="下一首播放">
+  <Icon icon="mdi:playlist-play" />
+</button>
+```
+
+Add `playNext: []` to `defineEmits`.
+
+**Caller updates** — `Home.vue`, `Library.vue`, `Search.vue`, `History.vue`,
+`Playlist.vue`: each `<SongCard>` usage adds
+`@playNext="store.playNextSong(song)"`.
+
+**Queue.vue** is intentionally **not** updated — clicking "play next" on a
+song already in the queue would create a confusing duplicate.
+
+## Edge Cases
+
+| Case | Behavior |
+|---|---|
+| `prev` with empty history in Sequential mode | Walks `currentIndex - 1`; returns null at index 0 (existing) |
+| `prev` with empty history in Random/RandomLoop | Returns null (no past to recover) |
+| Repeated `prev` past start of history | Pops what's there, then falls back to index walk; eventually null |
+| `addNext` while `currentIndex == -1` (nothing played yet) | Falls through to push; queue.play() will pick it as first |
+| `addNext` while playing and queue size = 1 | Inserts at index 1; current index unchanged; next() will advance to it |
+| `remove` removes a song whose index is in history | Entry dropped; shifted accordingly |
+| Mode switched mid-playback | History cleared (intentional — mode change is a context boundary) |
+| `addNext` then `prev` | Inserted song was never played → not in history; prev pops the previously-played song, NOT the just-inserted one |
+
+## Files Touched
+
+- `src/audio/queue.ts` — history field, `pushHistory`, `addNext`, rewritten `prev`, mutator updates
+- `src/audio/queue.test.ts` (or add if missing) — unit tests for history behavior + addNext shift logic
+- `src/bot/instance.ts` — register `!playnext` / `!pn` command handler
+- `src/web/api/player.ts` — new `/play-next-song` route
+- `web/src/stores/player.ts` — `playNextSong` action
+- `web/src/components/SongCard.vue` — third action button + emit
+- `web/src/views/Home.vue` — wire `@playNext`
+- `web/src/views/Library.vue` — wire `@playNext`
+- `web/src/views/Search.vue` — wire `@playNext`
+- `web/src/views/History.vue` — wire `@playNext`
+- `web/src/views/Playlist.vue` — wire `@playNext`
+
+## Test Plan
+
+**Unit (vitest, `queue.test.ts`):**
+- prev with empty history in Sequential: walks back, null at index 0
+- prev with empty history in Random: returns null
+- next → next → next → prev pops correctly; prev again pops earlier
+- prev after `clear()` returns null (history reset)
+- prev after `setMode()` returns null (history reset)
+- `remove(idx)` drops from history and shifts entries > idx
+- `addNext` while empty: appends
+- `addNext` while playing index 2 in a 5-song queue: ends up at index 3, currentIndex still 2, queue size 6
+- `addNext` then `next()`: plays the inserted song
+- `addNext` shifts existing playedIndices and history correctly
+
+**Integration (manual smoke):**
+- Random mode: play 4 songs, hit `prev` 3 times → walks back through history
+- Click "下一首播放" on a search result → next song after current is the chosen one
+- `!playnext 七里香` → bot replies "已加入下一首：..."; current keeps playing; next song is 七里香
+- `!playnext` while idle → starts playing immediately
+
+**Regression:**
+- Existing 161 source-tree tests still pass.
+- TypeScript `tsc --noEmit` and `npm run build:web` clean.

+# 自定义机器人头像 + 专辑搜索/播放
+
+**Date:** 2026-05-07
+**Status:** Spec — pending implementation
+**Issue:** [#51](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/51)
+
+## Problem
+
+Issue #51 的两个独立但同源的反馈：
+
+1. **机器人头像无法固定** — 当前 `ProfileConfig.avatarEnabled` 控制是否同步专辑封面，但没有任何"上传一张固定头像"的入口。多 bot 房间里用户依赖头像辨识具体 bot，封面跟着歌变会让识别成本变高。
+2. **网页端搜索不能播放整张专辑** — `SearchResult.albums` 类型字段存在但所有 provider 都返回 `[]`，搜索 API `/search/all` 只聚合 `songs`；Search.vue 里也只渲染 SongCard。Netease 后端 `getAlbumSongs` 已实现，唯独缺把搜索/UI 连起来。
+
+两件事独立，分两个 PR；本 spec 同时覆盖两块以保持 #51 的单一 issue 关系。
+
+## Goal
+
+### 自定义头像
+
+- "创建新实例"弹窗里有一个"自定义头像"上传/预览控件（PNG/JPG/WebP，≤200 KB，与 TS3 头像上限一致）
+- Settings 已有的"同步头像"那行下面增加同等的"自定义头像"卡片，可以在已存在的 bot 上随时改/删
+- 行为矩阵：
+
+  | `avatarEnabled` | 有自定义 | 播放时 | 停播时 |
+  |---|---|---|---|
+  | true  | 是 | 跟当前歌曲封面 | **回到自定义** |
+  | true  | 否 | 跟当前歌曲封面 | 清空（保持现状） |
+  | false | 是 | 一直显示自定义 | 一直显示自定义 |
+  | false | 否 | 不主动改 | 不主动改 |
+
+### 专辑搜索
+
+- 搜索结果里能看到"专辑"分区（先支持 Netease + QQ，bilibili/youtube 仍返回 `[]`）
+- 点专辑卡片进入详情页 → 看到曲目列表 + 顶部"播放全部 / 加入队列"
+
+## Out of Scope
+
+- 头像格式自动转换（用户传 GIF/BMP 不接受，前端校验拒掉）
+- 头像服务端自动 resize（本期保持"上传时校验大小"，后期可加 sharp/jimp 但不在本期）
+- 专辑搜索的多平台聚合排序（按 `netease → qq` 简单拼接，与现有 `songs` 聚合一致）
+- 专辑详情页的"喜欢/收藏"按钮（playlist 详情页本身也没有）
+- 专辑作为推荐位（Home 不出现"推荐专辑"这一栏）
+- bilibili / youtube 的专辑概念（这两个平台无对应 API）
+
+## Architecture
+
+### 自定义头像
+
+#### 存储
+
+- 文件落地 `data/avatars/<botId>.<ext>`（仿 `data/cookies/<platform>.json`，Docker volume 友好）
+- DB schema：`bot_instances` 表新增 `custom_avatar_path` TEXT NULL（存相对路径，如 `avatars/<botId>.png`），通过 `migrateSchema()` 迁移
+- 加载时机：`BotProfileManager` 构造时把文件读到内存 `Buffer`，避免每次 stop 都读盘
+
+#### 后端 API
+
+新增 `src/web/api/bot.ts` 里（如不存在则在 `instance.ts` 同源处）：
+
+- `POST /api/bot/:id/avatar` (multipart) — 校验大小 ≤200 KB、MIME ∈ {png,jpeg,webp}；写盘 + 更新 DB；广播给运行中实例（重新加载 buffer + 立即 `applyIdleAvatar()`）
+- `DELETE /api/bot/:id/avatar` — 删盘 + 清 DB；运行中实例切回原 clear 语义
+- `GET /api/bot/:id/avatar` — 直接 `res.sendFile`（带强 ETag）供前端预览
+
+#### `BotProfileManager` 改动
+
+新增字段 + 方法：
+
+```ts
+private customAvatar: Buffer | null = null;
+
+setCustomAvatar(buf: Buffer | null): void;
+private async applyIdleAvatar(gen: number): Promise<void>;  // 上传 customAvatar
+```
+
+修改：
+
+- `clearAvatar(gen)` → `if (this.customAvatar) { applyIdleAvatar(gen) } else { 当前逻辑 }`
+- `onConnect()` 新增：`if (!avatarEnabled && customAvatar) applyIdleAvatar(gen)`
+- `setCustomAvatar(buf)`：更新内存 buffer，并触发 `applyIdleAvatar` 一次（仅当当前应该显示 idle avatar 时，即没在播放或 avatarEnabled=false）
+
+#### 前端
+
+新组件 `web/src/components/AvatarUpload.vue`：
+
+- props: `botId?` (上传时空表示走临时 base64 缓存)、`v-model:value`
+- 拖拽 / 文件选择 / 预览圆框 / 删除按钮
+- 内部 `axios.post('/api/bot/<id>/avatar', formData)` 或在创建表单里把 base64 与表单一同提交
+
+接入点：
+
+- 创建实例弹窗（搜索 `BotEditor.vue` 或类似）—— 表单提交后用返回的 botId 再 POST 头像；或者表单本身保存 base64 等创建完成后由后端解码落盘
+- Settings.vue：在 features 列表中插入一行"自定义头像"，右侧渲染 `<AvatarUpload :bot-id="botId" />`
+
+### 专辑搜索 / 详情
+
+#### 后端
+
+`src/music/netease.ts` `search()`：
+
+- 多发一个 `cloudsearch?type=10` 请求，把返回的 `result.albums[]` 映射成 `Album[]` 填进 `SearchResult.albums`
+- 字段 `id` / `name` / `coverUrl` (`picUrl`) / `artist` (`artists[].name.join(' / ')`)
+
+`src/music/qq.ts` `search()`：
+
+- 在现有 `req_0` 旁增加 `req_album: { module: "music.search.SearchCgiService", method: "DoSearchForQQMusicDesktop", param: { searchid, query, search_type: 8 } }`，映射 `body.album.list[]`
+
+`src/web/api/music.ts` `/search/all`：
+
+- 在响应里增加 `albums` 和 `playlists`，与 `songs` 一同合并
+
+`/album/:id` 已存在，无需改动。
+
+#### 前端
+
+- `web/src/views/Search.vue`：响应 schema 升级为 `{songs, albums, playlists}`；模板加入两个新分区（"专辑"、"歌单"），各自一个简单的卡片网格（参考 Home.vue 的 `playlist-grid`）
+- 新路由 `/album/:id` → 复用 `Playlist.vue`，把它的 `loadPlaylist()` 重构为根据 `route.path` 决定调 `/playlist/:id` 还是 `/album/:id`，或者新建 `Album.vue` 内部 import 同一个 `<PlaylistDetail />` 子组件
+  - **方案选择**：拆出 `<PlaylistDetail :endpoint="...">` 组件 + `Album.vue` / `Playlist.vue` 两个薄壳。当前 `Playlist.vue` 内部仅 ~60 行模板，单文件改造比新建 PlaylistDetail 子组件更小，先用最小改动：在 `Playlist.vue` 内根据 `route.meta.kind === 'album'` 切换 endpoint
+- 路由：`router/index.ts` 加 `{ path: '/album/:id', component: Playlist, meta: { kind: 'album' } }`
+
+### 拆分
+
+**两个 PR：**
+
+1. `feat(profile): custom bot avatar with idle/playback precedence`
+   - DB migration + ProfileManager 改动 + 上传 API + AvatarUpload.vue + 接入两个表单
+2. `feat(search): album section in search results + album detail playback`
+   - netease/qq search 扩展 + /search/all + Search.vue 分区 + Playlist.vue 复用为 album
+
+## Testing
+
+### 自定义头像
+
+- 单元：DB 迁移加 `custom_avatar_path` 列幂等；上传 API 校验大小/MIME；ProfileManager.applyIdleAvatar 在 onSongChange(null) 后被调用
+- 集成：mock TS3Client 验证 fileTransferInitUpload 收到的 buffer 是 customAvatar
+- 手动：本地起 bot 上传一张 png → 检查头像；播一首歌 → 头像切封面；停止 → 头像回到 png；关掉 avatarEnabled 重启 → 头像直接是 png
+
+### 专辑搜索
+
+- 单元：netease/qq `search()` 测试：响应包含 albums 字段，长度 > 0 (mock fixture 必须含 album 段)
+- 集成：`/search/all` 响应 schema 包含 `albums`/`playlists`
+- 手动：搜"周杰伦" → 看到歌曲 + 专辑 + 歌单三个分区；点专辑 → 详情页 → 播放全部 → 队列加上整张专辑
+
+## Migration
+
+DB 迁移：`bot_instances.custom_avatar_path` TEXT NULL，默认 NULL。已存在 bot 不受影响。
+
+## Open Questions
+
+- TS6 协议路径下 `fileTransferInitUpload` 是否一致？（既有 avatar 流程已经覆盖 TS3 + TS6，本期沿用同一路径，不单独验证）
+- 头像超过 200 KB 时前端用 Canvas 自动 resize 还是直接拒？— **决定：拒，错误提示"请压缩到 200KB 以内"**，简单可控

+# WebUI Authentication
+
+**Date:** 2026-05-27
+**Status:** Spec — pending implementation
+**Branch:** `feat/webui-auth`
+
+## Problem
+
+WebUI 的所有后端端点和 WebSocket 当前没有任何鉴权：
+
+- `src/web/server.ts` 注册的 `/api/bot`、`/api/player`、`/api/music`、`/api/auth`、`/api/config/public-url`、`/api/health`、`/ws` 均无中间件拦截。
+- 静态前端通过 `express.static()` 直接对外提供。
+
+后果：任何能访问 WebUI 端口（默认 `3000`）的人都能控制 bot、修改配置、操控播放，并触发对网易云 / QQ / Bilibili 的登录二维码流程。一旦 WebUI 端口暴露公网（无论是直接绑定 `0.0.0.0`、还是经 nginx 反代），即被任意访客接管。
+
+## Goal
+
+为 WebUI 增加用户名 + 密码登录，覆盖所有 HTTP `/api/*` 端点（除显式公共白名单）以及 `/ws` WebSocket，使未登录访客无法调用任何敏感接口或观察 bot 状态。
+
+## Out of Scope（明确不做）
+
+- 登录失败的限流 / 锁定（无 brute-force 防御；可放在反代层；后续 PR 单独做）
+- 角色与权限（admin / viewer）—— 全员同权
+- 密码重置流程（不挂邮件；仅提供登录后 `change-password`）
+- 双因素认证（2FA）
+- "记住我" / 绝对过期 vs 滑动过期的可配置
+- 旧版"无鉴权"兼容开关（`requireAuth=false`）—— 合入后所有部署强制启用鉴权
+- 现有 `config.adminPassword` 字段的迁移 —— 保留为未使用字段，避免破坏旧 `config.json`
+
+## Non-functional Constraints
+
+- 不引入需要原生编译的依赖（Windows 用户多，build tools 不稳定）。密码哈希用纯 JS 的 `bcryptjs`。
+- Cookie 行为必须兼容现有 `trustProxy` 反代部署。
+- 升级路径：旧用户首次启动新版本 → 自动进入 `/setup` 创建首位 admin；期间所有 `/api/*` 仍拒绝访问。期间不存在"裸奔窗口"。
+- 后续维护者要能在不阅读 `requireAuth` 内部细节的情况下，把新路由挂到 `/api/*` 下并自动获得鉴权。
+
+## Architecture
+
+### 数据层（`src/data/`）
+
+扩展 `src/data/database.ts` 的 schema-migration 块，新增两张表：
+
+```sql
+CREATE TABLE IF NOT EXISTS users (
+  id           TEXT PRIMARY KEY,                 -- uuid v4
+  username     TEXT NOT NULL UNIQUE COLLATE NOCASE,
+  passwordHash TEXT NOT NULL,                    -- bcryptjs, 12 rounds
+  createdAt    INTEGER NOT NULL,
+  updatedAt    INTEGER NOT NULL
+);
+
+CREATE TABLE IF NOT EXISTS sessions (
+  id          TEXT PRIMARY KEY,                  -- sha256(rawToken) hex
+  userId      TEXT NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+  createdAt   INTEGER NOT NULL,
+  expiresAt   INTEGER NOT NULL,                  -- ms epoch
+  lastSeenAt  INTEGER NOT NULL
+);
+CREATE INDEX IF NOT EXISTS idx_sessions_userId    ON sessions(userId);
+CREATE INDEX IF NOT EXISTS idx_sessions_expiresAt ON sessions(expiresAt);
+```
+
+**为什么 `sessions.id` 存 sha256(token) 而不是 token 本身：** 若 SQLite 文件被泄露（备份、误传、磁盘扫描），原始 token 会让攻击者直接冒充任意已登录用户。存 hash 后只能爆破。代价仅是每次请求一次 sha256。
+
+新模块：
+
+`src/data/users.ts`
+- `createUser(username, password): User` — 在事务里 INSERT；遇到 UNIQUE 冲突抛出 `UsernameTakenError`
+- `findByUsername(username): User | null`
+- `verifyPassword(plain, hash): Promise<boolean>` — bcryptjs compare
+- `countUsers(): number` — 用于 `/needs-setup`
+- `changePassword(userId, newPassword): void`
+
+`src/data/sessions.ts`
+- `createSession(userId): { token: string; expiresAt: number }` — 生成 32 字节随机 token（`crypto.randomBytes(32).toString('base64url')`），存 sha256
+- `validateAndTouch(rawToken): { userId, username } | null` — 单次 SQL JOIN：查 session + user；过期 → 返回 null + 删除该行；否则若 `now - lastSeenAt > 1h` 则 UPDATE 滑动续期到 `now + 7d`
+- `deleteSession(rawToken): void` — 退出
+- `deleteAllForUser(userId, exceptToken?): void` — change-password 时调用，可保留当前会话
+- `cleanupExpired(): void` — 定时任务
+
+### HTTP 层（`src/web/`）
+
+#### 新增中间件
+
+`src/web/middleware/requireAuth.ts`
+```
+读取 req.cookies.tsmb_session
+  → 缺失 → 401 { error: "unauthenticated" }
+  → 调 sessions.validateAndTouch
+  → null → 清 cookie + 401
+  → 有效 → req.user = { id, username }; next()
+```
+
+`src/web/middleware/csrf.ts`
+```
+若 method ∈ {GET, HEAD, OPTIONS} → next()
+否则要求 req.headers.origin || req.headers.referer 的 host 与 req.get('host') 一致
+  → 不一致或两者都缺失 → 403 { error: "bad origin" }
+```
+
+#### 新路由：`src/web/api/session.ts`
+
+挂在 `/api/session`，全部公共（不挂 requireAuth）：
+
+| Method | Path | 行为 |
+|---|---|---|
+| GET | `/needs-setup` | `{ needsSetup: users.countUsers() === 0 }` |
+| POST | `/setup` | Body `{ username, password }`。在事务内再次检查 `countUsers() === 0`：是则 INSERT user + 立刻 createSession + Set-Cookie + 200 `{ id, username }`；否则 409 `{ error: "already initialized" }` |
+| POST | `/login` | Body `{ username, password }`。匹配则 createSession + Set-Cookie + 200；不匹配则等待 250ms 后 401 `{ error: "invalid credentials" }`（常量时间延迟，降低用户名枚举风险） |
+| POST | `/logout` | 删 session，清 cookie，204 |
+| GET | `/me` | 走 requireAuth；返回 `{ id, username }` |
+| POST | `/change-password` | 走 requireAuth；Body `{ oldPassword, newPassword }`；通过则 changePassword + deleteAllForUser(except 当前) + 204 |
+
+> `/me` 与 `/change-password` 例外地需要 requireAuth —— 在路由内单独挂中间件，避免污染 `/api/session/*` 的公共属性。
+
+#### Cookie 规范
+
+- 名称：`tsmb_session`
+- 值：32 字节 random → base64url
+- 属性：`HttpOnly; SameSite=Lax; Path=/; Max-Age=604800`（7 天）
+- `Secure` 标志：当 `req.secure === true`（依赖 `trustProxy` + `X-Forwarded-Proto`）；本地 HTTP 调试时不加，避免 cookie 被丢弃
+
+#### 装配顺序（`src/web/server.ts`）
+
+```ts
+app.use(express.json({ limit: "400kb" }));
+app.use(cookieParser());                              // 新增
+
+// 公共
+app.get("/api/health", …);
+app.get("/api/config/public-url", …);
+app.use("/api/session", createSessionRouter(...));
+
+// 闸门（仅作用于下方注册的 /api/* 路由）
+app.use("/api", csrfOriginCheck);
+app.use("/api", requireAuth);
+
+// 受保护
+app.use("/api/bot",    createBotRouter(...));
+app.use("/api/music",  createMusicRouter(...));
+app.use("/api/player", createPlayerRouter(...));
+app.use("/api/auth",   createAuthRouter(...));        // 音乐平台 QR
+
+// 静态 SPA（公共，前端自行判定登录态后跳转）
+app.use(express.static(staticDir));
+app.get(/^(?!\/api|\/ws)/, sendIndex);
+```
+
+> Express 的 `app.use` 仅对匹配前缀生效。公共路由先注册即可命中；之后的 `app.use("/api", …)` 闸门只在公共路由未匹配时执行，因此 `/api/health`、`/api/config/public-url`、`/api/session/*` 不会被闸门拦截。
+
+#### 定时清理
+
+`server.start()` 内启动 `setInterval(cleanupExpired, 60 * 60 * 1000)`，`server.stop()` 内 `clearInterval`。
+
+### WebSocket 层（`src/web/websocket.ts` + `src/web/server.ts`）
+
+改造为手动 upgrade：
+
+```ts
+const wss = new WebSocketServer({ noServer: true });
+
+server.on("upgrade", (req, socket, head) => {
+  if (req.url !== "/ws") { socket.destroy(); return; }
+  const session = validateCookieFromHeaders(req.headers.cookie);
+  if (!session) {
+    socket.write("HTTP/1.1 401 Unauthorized\r\nConnection: close\r\n\r\n");
+    socket.destroy();
+    return;
+  }
+  wss.handleUpgrade(req, socket, head, (ws) => {
+    (ws as any).userId = session.userId;
+    wss.emit("connection", ws, req);
+  });
+});
+```
+
+`validateCookieFromHeaders` 在 `src/web/auth/validateSession.ts` 提供，HTTP 中间件与 WS upgrade 共用同一实现，确保不会出现"HTTP 拒、WS 放行"或反之的偏差。
+
+不需要在 upgrade 上单独做 CSRF：浏览器在跨站 WebSocket 请求里仍会带 Origin 头，可在 validate 之外顺手比对 `req.headers.origin` host 与 `req.headers.host` 一致；不一致直接拒绝。
+
+### 前端层（`web/`）
+
+#### 新视图
+
+- `web/src/views/Login.vue` — 用户名 + 密码表单 → POST `/api/session/login` → 成功跳 `next` 或 `/`
+- `web/src/views/FirstRunSetup.vue` — 同样表单 + 二次确认密码 → POST `/api/session/setup` → 成功后自动登录并跳 `/`
+  - 名称避免与既有 `Setup.vue`（bot 创建向导）冲突
+
+#### Session 状态
+
+新增 `web/src/composables/useSession.ts`：暴露 `currentUser: Ref<User|null>`、`refresh()`、`logout()`、`needsSetup: Ref<boolean>`。在 `App.vue` mount 时调用 `refresh()`。
+
+#### 路由守卫（`web/src/router/index.ts`）
+
+- 公共路由：`/login`、`/setup`
+- 全局 `beforeEach`：
+  1. 先 `GET /api/session/needs-setup`（仅在 `needsSetup` 未知时拉一次并缓存）
+  2. `needsSetup === true` 且目标不是 `/setup` → `redirect('/setup')`
+  3. 否则 `GET /api/session/me`，401 且目标非公共路由 → `redirect('/login?next=<path>')`
+
+#### API 客户端
+
+- 所有 `fetch` 改为 `credentials: 'same-origin'`（若现有有 wrapper 则改一处；否则按文件逐个改 —— 实施时由 plan 列出）
+- 包一层 401 拦截器：任意受保护请求返回 401 → 清 `currentUser` → `router.push('/login')`
+
+#### UI
+
+- 顶栏新增已登录用户名 + "退出"按钮（POST `/logout` → `router.push('/login')`）
+- 修改密码入口暂放在已有的"设置"页签内（若无则新增极简 section）
+
+### 依赖
+
+新增到 `package.json`：
+
+```
+"bcryptjs": "^2.4.3",
+"cookie-parser": "^1.4.6",
+"@types/bcryptjs": "^2.4.6",
+"@types/cookie-parser": "^1.4.7"
+```
+
+不引入 `express-session`、`jsonwebtoken`、`passport` 等更大栈。
+
+## Data Flow
+
+### 首次启动
+
+```
+Browser → GET /         → static SPA
+SPA mounted → GET /api/session/needs-setup → { needsSetup: true }
+SPA → router.replace('/setup')
+User submits form → POST /api/session/setup
+Server (TX): countUsers() === 0 → INSERT user → createSession → Set-Cookie → 200
+SPA → currentUser refresh → router.replace('/')
+```
+
+### 已部署用户升级
+
+旧 `config.adminPassword` 字段保留不动；首次启动新版本仍会因 `users` 表为空而进入 setup 流程 —— 旧字段不被采纳，避免歧义。
+
+### 后续登录
+
+```
+SPA → GET /api/session/me → 401
+SPA → router.replace('/login?next=/queue')
+User submits → POST /api/session/login → Set-Cookie + 200
+SPA → currentUser refresh → router.replace('/queue')
+```
+
+### 受保护请求
+
+```
+SPA → fetch('/api/bot', { credentials: 'same-origin' })
+Server requireAuth: validateAndTouch(cookie)
+  → ok → req.user 注入 → 业务路由处理
+  → 不 ok → 401 → SPA 拦截器跳 /login
+```
+
+### WebSocket
+
+```
+SPA → new WebSocket(`${wsScheme}://${host}/ws`)   // 浏览器自动带 cookie
+Server upgrade handler: validateCookieFromHeaders
+  → ok → handleUpgrade → connection event
+  → 不 ok → HTTP 401 写回原始 socket → destroy
+```
+
+## Error Handling
+
+| 场景 | HTTP 响应 | 备注 |
+|---|---|---|
+| 未带 cookie | 401 `{ error: "unauthenticated" }` | requireAuth |
+| Cookie 解析失败 / token 不存在 | 401 + `Set-Cookie tsmb_session=; Max-Age=0` 清掉 | 自愈 |
+| Session 过期 | 同上 + DELETE 该行 | validateAndTouch 内部完成 |
+| 用户名/密码不匹配 | 401 `{ error: "invalid credentials" }` + 250ms 延迟 | 不区分"用户不存在"和"密码错"两类 |
+| `setup` 时已存在用户 | 409 `{ error: "already initialized" }` | 防止重复初始化 |
+| `setup` 用户名重复 | 在 `/setup` 流程中不可能（只允许 0 → 1） |  |
+| `change-password` 旧密码错 | 401 `{ error: "invalid credentials" }` |  |
+| CSRF Origin 不匹配 | 403 `{ error: "bad origin" }` |  |
+| WS 无 cookie / 校验失败 | 写回 HTTP/1.1 401 并 destroy socket | 在握手前拒绝，避免 onopen 假成功 |
+
+所有错误响应统一 `{ error: string }` 形式，匹配现有 API 风格。
+
+## Testing Strategy
+
+### 单元（vitest）
+
+`src/data/users.test.ts`
+- createUser 成功后 findByUsername 命中（大小写不敏感）
+- 重复 username 抛 UsernameTakenError
+- verifyPassword 正反例
+- changePassword 之后旧哈希不再验证通过
+
+`src/data/sessions.test.ts`
+- createSession 返回的 token 不是 DB 内 id（DB 内是 sha256(token)）
+- validateAndTouch 过期记录返回 null 且记录被删
+- validateAndTouch 未过 1h 不写 DB；过 1h 后写 DB（用 `Date.now` mock 验证）
+- deleteAllForUser(exceptToken) 保留指定会话
+
+### 集成（vitest + supertest，真 SQLite in-memory）
+
+`src/web/api/session.test.ts`
+- empty DB → /needs-setup 返回 true；/setup 成功；/needs-setup 再调返回 false；二次 /setup 返回 409
+- /login 成功后受保护路由 (`GET /api/bot`) 200；不带 cookie 401
+- /logout 之后同一 cookie 调受保护路由 401
+- /change-password 后 a) 旧密码 /login 失败 b) 新密码 /login 成功 c) 之前签发的其他 cookie 失效，当前 cookie 仍可用
+
+`src/web/middleware/csrf.test.ts`
+- 带匹配 Origin 的 POST 通过
+- Origin 与 host 不匹配 → 403
+- 同样规则适用 Referer
+- GET 永远通过
+
+`src/web/websocket.test.ts`（新增或扩展）
+- 无 cookie 的 ws 握手 → 收到 HTTP 401，socket 关闭
+- 带有效 cookie → 握手成功，收到 init 消息
+- Session 删除后已建立的 ws **不会**被主动断（明确记录此妥协 —— 见 Trade-offs）
+
+### 前端
+
+不在本 PR 引入新的 e2e 框架。手动用例（在 PR 描述里列）：
+- 全新数据库启动 → 自动跳 /setup → 创建账户 → 进入主界面
+- 退出 → 自动跳 /login
+- 关闭浏览器 7 天内再开 → 仍登录
+- 登录态下后端重启清空 sessions → 任意 API 调用 → 自动跳 /login

+
+## Trade-offs / 已知妥协
+
+1. **会话失效不主动断 WS** —— 后台 deleteSession 后，已有 WS 仍在跑（直到客户端断或服务端进程重启）。原因：WS 长连接没有"每条消息再次鉴权"的廉价手段；为此引入会浪费时间。影响面有限：WS 只推状态、不接收 mutating 命令；所有写操作仍走 HTTP。
+2. **无登录限流** —— 见 Out of Scope。若部署面向公网，建议在反代层加 limit（如 nginx `limit_req`）。
+3. **`config.adminPassword` 留作未使用字段** —— 不迁移、不读取。后续 PR 可移除并加 schema migration。当前保留是为避免破坏旧 `config.json` 解析。
+4. **单一管理员模型** —— 多用户表已存在，但 UI 当前不暴露增删用户。下一个 PR 再加用户管理界面。
+5. **Origin/Referer CSRF 检查** —— 不是 token，但配合 `SameSite=Lax` 已能挡掉常规 CSRF 攻击。代价：会拒绝缺 Origin/Referer 的非浏览器客户端 POST 请求（如裸 curl）—— 这是预期行为。

+# Fine-grained account permissions — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) (item E — the maintainer's permission-management idea)
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Scope
+
+Issue #79 bundles five things. This spec covers **only item E**: allow an admin to
+grant each non-admin (member) account a set of capabilities and a list of bots they
+may control. The other items are handled in separate PRs and are **out of scope**
+here:
+
+- #1 Guest mode (login-less playback)
+- #2 Dedicated-link hides other bots (subsumed conceptually by E's bot allow-list, but the link-specific UX is separate)
+- #3 Auto-pause when channel empty
+- #4 Dedicated link loses bot binding on refresh (a bug)
+
+## Problem
+
+Today the bot has a coarse two-role system: `admin | member` (single `role` column,
+read live per request). `requireAdmin` gates only `/api/users` and `/api/audit`.
+**Every other action — create/edit/delete bots, start/stop, all playback & queue
+control, set platform login cookies, set audio quality — is open to any logged-in
+member, on every bot.** Admins want to delegate limited control to members without
+handing them full power.
+
+## Decisions (from brainstorm)
+
+1. **Model = capability flags + per-member bot allow-list** (not a per-bot×per-action
+   matrix, not role templates).
+2. **Defaults:** on upgrade, existing members are backfilled with full capabilities +
+   all bots (no behavior change); newly-created members get a **basic tier**.
+3. **Bot allow-list semantics:** an explicit "all bots" toggle OR a specific list;
+   empty list = no bots controllable. Members **cannot see** bots outside their
+   allow-list (hidden, not merely disabled).
+4. **Capability set (5 toggles)** — see below; basic tier = playback + queue + all bots.
+5. **Admin is a super-user** (bypasses all checks). The last admin cannot be demoted
+   (existing invariant preserved). Permission grants/revokes are written to the
+   existing audit log.
+
+## Capability taxonomy
+
+| Capability token | Covers | Scope |
+|---|---|---|
+| `player.control` | play/pause/resume/next/prev/stop/seek/volume/mode | per-bot (allow-list) |
+| `player.queue` | search-add / clear / remove / play-at / playlist / album / play-song | per-bot (allow-list) |
+| `bot.manage` | create / edit / delete / start / stop / avatar / profile / idle settings | global (create) + per-bot (operate a specific bot) |
+| `platform.auth` | set NetEase/QQ/Bilibili cookie, QR, SMS | **global** (shared credentials) |
+| `quality` | set audio quality per platform | **global** |
+
+Bot scope is independent of capabilities: a member with `player.control` can only
+exercise it on bots in their allow-list (or all, if the "all bots" flag is set).
+`platform.auth` and `quality` are global capabilities with no bot scope.
+
+**Basic tier** (new members): `{ player.control, player.queue }` + `bots.all = true`.
+A new member can play/queue on every bot but cannot manage bots, change credentials,
+or change quality.
+
+## Data model (SQLite, additive — follows existing `CREATE TABLE IF NOT EXISTS` pattern)
+
+```sql
+-- capability tokens + the "all bots" flag (stored as token 'bots.all')
+CREATE TABLE IF NOT EXISTS user_permissions (
+  userId     TEXT NOT NULL,
+  permission TEXT NOT NULL,
+  PRIMARY KEY (userId, permission),
+  FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE
+);

+  PRIMARY KEY (userId, botId),
+  FOREIGN KEY (userId) REFERENCES users(id) ON DELETE CASCADE

+CREATE INDEX IF NOT EXISTS idx_user_bot_access_userId ON user_bot_access(userId);
+```
+
+- Admins have no rows (they bypass). Only members are constrained.
+- `bots.all` present ⇒ all bots (incl. future ones). Absent ⇒ only `user_bot_access`
+  rows; empty ⇒ none.
+- `foreign_keys = ON` and WAL are already enabled; cascade-on-user-delete works.
+- `user_bot_access.botId` references bot instance ids; when a bot is deleted, its
+  access rows should be cleaned up (either an FK to the bot table if one exists, or an
+  explicit cleanup in `BotManager.removeBot` / `PermissionStore.pruneBot(botId)`).
+
+New `PermissionStore` in `src/data/permissions.ts` (mirrors `createUserStore` /
+`createSessionStore`: prepared statements + an interface). Methods:
+`getCapabilities(userId)`, `getBotAccess(userId)` → `'all' | string[]`,
+`setPermissions(userId, { capabilities, bots })`, `pruneBot(botId)`.
+
+## Backend enforcement (real 403 — not just hidden UI)
+
+- **`req.user` widened** to carry `capabilities: Set<string>` and bot access. Loaded in
+  `requireAuth` (one extra lookup, or a JOIN in the session query). The same
+  `{id,username,role,capabilities,bots}` shape must be kept in sync in the three places
+  it is built today: `requireAuth.ts`, `session.ts` `requireAuthInline`, and the WS
+  upgrade handler in `server.ts` (WS only needs it if a push action becomes gated).
+  Because it's read live, permission changes take effect immediately (no re-login).
+- **`requirePermission(cap)`** middleware (new, mirrors `requireAdmin.ts`): 401 if no
+  user; allow if `role === 'admin'` or `capabilities.has(cap)`; else 403.
+- **`requireBotAccess`** helper: allow if admin or `bots.all` or botId ∈ access list;
+  else 403. Mounted on the player router's existing `/:botId` choke-point
+  (`src/web/api/player.ts`) and on each `:id` route in `src/web/api/bot.ts`
+  (start/stop/edit/delete/avatar/profile).
+- **Route → capability mapping:**
+  - `/api/player/:botId/*` playback actions → `player.control` (+ `requireBotAccess`)
+  - `/api/player/:botId/*` queue actions → `player.queue` (+ `requireBotAccess`)
+  - `/api/bot` create, `/api/bot/:id` edit/delete, `/api/bot/:id/start|stop|avatar|profile`, `/api/bot/settings` → `bot.manage` (+ `requireBotAccess` for the `:id` ones)
+  - `/api/auth/*` (cookie/QR/SMS) → `platform.auth`
+  - `/api/music/quality` POST → `quality`
+- **`GET /api/bot`** filters its result to the caller's allowed bots for members
+  (admins see all). This is what "hides" disallowed bots in the UI.
+
+## Management API (admin-only, added to the existing users router)
+
+- `GET /api/users/:id/permissions` → `{ capabilities: string[], bots: 'all' | string[] }`
+- `PUT /api/users/:id/permissions` → body `{ capabilities, bots }`; validates tokens
+  against the known set and botIds against existing bots; writes audit
+  `user.permissions_changed`.
+- `GET /api/session/me` is extended to include the **current** user's
+  `{ capabilities, bots }` so the frontend can gate UI. (admins report effectively-all.)
+
+## Frontend
+
+- `useSession` extends `User` with `capabilities` + bot scope and exposes
+  `can(cap)` and `canControlBot(botId)` helpers.
+- **Navbar bot selector** filters `store.bots` to controllable bots (others hidden);
+  `activeBot` fallback and `fetchBots` default only ever land on an allowed bot.
+- **Player / Settings** hide controls and whole sections a member lacks: platform
+  login, audio quality, and bot create/edit/delete are hidden without the matching
+  capability; playback/queue buttons hidden without `player.control` / `player.queue`.
+- **Admin permission editor:** in the Settings → User Management list, each member row
+  gets a "权限" editor — capability checkboxes + a bot allow-list with an "全部机器人"
+  toggle. Saving calls `PUT /api/users/:id/permissions`.
+
+## Defaults & migration
+
+- New tables created idempotently in `initTables`.
+- **One-time backfill** (guarded so it runs once): every existing `member` gets all
+  five capabilities + `bots.all`. Admins are skipped (they bypass). This preserves
+  current behavior for existing members on upgrade.
+- **New member default** (`POST /api/users` with role member): capabilities
+  `{ player.control, player.queue }` + `bots.all` (basic tier).
+- Pre-existing accounts default to `role = 'admin'` per the current schema — those are
+  super-users and unaffected.
+
+## Testing (TDD)
+
+- `PermissionStore` unit tests (set/get capabilities + bot access; `'all'` vs list vs
+  empty; `pruneBot`).
+- `requirePermission` / `requireBotAccess` middleware tests (admin bypass; has/lacks
+  cap → 200/403; bot in/out of allow-list; `bots.all`).
+- API tests: member without cap → 403; with cap → 200; bot not allowed → 403/hidden;
+  `GET /api/bot` filtered for members, full for admin; `PUT .../permissions` validates
+  + audits.
+- Migration test: existing members backfilled to full + `bots.all`; new member gets
+  basic tier.
+
+## Non-goals
+
+- No per-bot×per-capability matrix, no custom role templates (YAGNI).
+- Guest mode, dedicated-link UX, auto-pause, and the refresh bug (#1–#4) are separate.
+- No change to the admin/member role concept itself; this layers capabilities under
+  the existing `member` role.

+# Auto-pause on empty channel — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) item 3
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Problem
+
+When everyone leaves the bot's voice channel, music keeps playing to an empty room.
+The maintainer wants an option to **auto-pause when the channel is empty** (no disconnect)
+and resume when someone returns.
+
+## Decisions (from brainstorm)
+
+- **Global toggle**, reusing the **already-declared but currently dead** `config.autoPauseOnEmpty`
+  (`src/data/config.ts`, default `true`). No per-bot granularity (YAGNI).
+- **Event-driven, near-instant** reaction (not the 30s poll alone) — subscribe to TS client
+  enter/leave/move events; keep the existing 30s idle poll as a fallback.
+- **Auto-resume only what we auto-paused** — a user-paused track is never auto-resumed.
+- Independent of the existing **idle-disconnect** (`idleTimeoutMinutes`): both share the same
+  emptiness signal but act independently (pause immediately; disconnect after N minutes).
+
+## Current state (verified)
+
+- `client.ts` `getClientsInChannel()` returns all clients in the bot's channel *including the
+  bot*; callers compute "others" as `length - 1`. No persistent roster.
+- The library emits `clientEnter` / `clientLeave` / `clientMoved`; `client.ts` currently only
+  *logs* `clientEnter` and does not re-emit leave/moved.
+- The idle poller in `instance.ts` (`_startIdlePoller`, every 30s) already computes
+  `userCount = getClientsInChannel().length - 1` and, when `<= 0`, schedules an
+  idle-disconnect after `idleTimeoutMinutes`.
+- `player.pause()` / `player.resume()` already pause/resume **without disconnecting** (ffmpeg
+  stays alive, no voice sent). The player only knows `idle|playing|paused` — there is **no**
+  auto-vs-user-pause distinction today.
+- `BotConfig.autoPauseOnEmpty` exists (default true) but is **read nowhere**.
+
+## Design
+
+### Occupancy signal (shared)
+Extract the idle poller's count into one method on `BotInstance`:
+`checkChannelOccupancy()` → queries `getClientsInChannel()`, computes `userCount = length - 1`,
+and drives **both** the existing idle-disconnect timer (unchanged behavior) **and** the new
+auto-pause logic below. It is called by:
+1. the existing 30s poll (fallback), and
+2. new TS event handlers.
+
+### Event subscription
+`client.ts`: subscribe to and **re-emit** `clientEnter`, `clientLeave`, `clientMoved` up to
+`BotInstance`. `BotInstance.setupTsEvents()` calls `checkChannelOccupancy()` on each (a re-query
+is simplest, since `clientLeave` carries no channel id). This gives near-instant pause/resume;
+the poll remains as a safety net.
+
+### Auto-pause logic (inside `checkChannelOccupancy`)
+Add a private `autoPaused = false` flag to `BotInstance`.
+- **Empty** (`userCount <= 0`): if `config.autoPauseOnEmpty` **and** `player.getState() === "playing"`
+  → `player.pause()`, `autoPaused = true`, emit `stateChange`. (Idle-disconnect timer still
+  scheduled as today.)
+- **Re-populated** (`userCount > 0`): if `autoPaused` **and** `player.getState() === "paused"`
+  → `player.resume()`, `autoPaused = false`, emit `stateChange`. (Idle timer cancelled as today.)
+
+### `autoPaused` bookkeeping (so user pauses are respected)
+Clear `autoPaused = false` in `cmdPause`, `cmdResume`, `cmdStop`, `cmdPlay`, and on
+connect/disconnect (the `disconnected` handler calls `player.stop()` → idle). Net effect: only a
+track *we* auto-paused gets auto-resumed; a user-paused track stays paused when someone returns.
+
+### Config wiring
+- `GET /api/bot/settings`: include `autoPauseOnEmpty` in the payload (alongside `idleTimeoutMinutes`).
+- `POST /api/bot/settings`: accept + validate a boolean `autoPauseOnEmpty`, `saveConfig`, and
+  propagate to live bots via a new `BotInstance.updateAutoPause(enabled)` (mirrors
+  `updateIdleTimeout`). Since the instance reads `this.config.autoPauseOnEmpty` live, propagation
+  can be as simple as updating the stored config reference / a field the check reads.
+- Frontend `Settings.vue` → the **行为设置** section (already `bot.manage`-gated): add a toggle
+  for `autoPauseOnEmpty` next to the idle-timeout control; load it in the settings fetch and send
+  it on save.
+
+## Components / files
+
+- `src/ts-protocol/client.ts` — subscribe + re-emit `clientEnter`/`clientLeave`/`clientMoved`.
+- `src/bot/instance.ts` — `autoPaused` field; `checkChannelOccupancy()` (refactored from the
+  idle poller, drives idle + auto-pause); event handlers; clear `autoPaused` in user commands +
+  connect/disconnect; `updateAutoPause(enabled)`.
+- `src/web/api/bot.ts` — `GET`/`POST /settings` handle `autoPauseOnEmpty`.
+- `web/src/views/Settings.vue` (+ player store settings load/save) — the toggle.
+- `src/data/config.ts` — field already exists (no change beyond confirming default).
+
+## Testing
+
+- **Decision unit test (TDD):** extract the pause/resume decision into a testable method, e.g.
+  `applyOccupancy(userCount)` operating on an injected fake player (`getState`/`pause`/`resume`)
+  + the `autoPaused` flag + the config flag. Cases: empty+playing+enabled → pause + `autoPaused`;
+  re-populated+`autoPaused`+paused → resume + clear; re-populated when NOT `autoPaused` (user
+  pause) → no resume; flag disabled → no pause; empty while idle (not playing) → no-op.
+- **API test:** `GET`/`POST /api/bot/settings` round-trips `autoPauseOnEmpty` (validates boolean,
+  persists, propagates).
+- Live TS event wiring is verified by code review + a manual run (can't unit-test a real server).
+
+## Non-goals
+
+- No per-bot toggle (global only). No change to idle-disconnect behavior. No new dependency.
+- Reaction relies on events the bot can already see (same-channel members are always in view);
+  no extra channel subscription needed.
+
+---
+
+## Update (2026-06): occupancy is event-driven & server-wide, not channel-filtered
+
+Live testing against a real TS3 server (with `@honeybbq/teamspeak-client` 0.2.2)
+invalidated two assumptions above. Recording the corrected model here so nobody
+reintroduces the old design:
+
+- **Default is OFF**, not on. See `getDefaultConfig()` in `src/data/config.ts`
+  and the rationale comment there.
+- **Query commands are unusable when others are present.** `clientlist`,
+  `channellist`, and `channelclientlist` ALL time out (~5–10s) whenever ≥2
+  clients are connected to the **server** (verified even when the two clients
+  are in *different* channels). They succeed only when the bot is the sole
+  client on the whole server. So `getClientsInChannel()` returns `[]` exactly
+  when occupancy matters, and `occupancyFromClientList(0)` returns `null`
+  ("unknown") so callers skip the decision rather than mis-reading it as empty.
+- **PAUSE** therefore only ever fires when the bot becomes alone on the server
+  (the one state where the query works). This is reliable and stays on the
+  query path (`refreshOccupancy()` + the 30s idle poller).
+- **RESUME** is armed directly from the `clientEnter` push event
+  (`shouldResumeOnReturn()` + `_resumeIfReturning()` in `instance.ts`), NOT from
+  a query. Because the bot only auto-pauses while alone, the sole way occupancy
+  can return while `autoPaused` is set is a fresh connection — delivered as
+  `clientEnter`. The resume branch never pauses (userCount is always > 0).
+- **Net semantics:** "pause when the server is empty (bot alone), resume when
+  someone connects." Channel granularity is **impossible** with this library:
+  `clientEnter`'s channel field is always `0` (library reads notify param `cid`
+  but enter-view carries `ctid`), and `clientMoved` delivery is flaky. Do NOT
+  attempt to layer `clientMoved.targetChannelID` channel-accuracy on top — it is
+  systematically wrong for direct-connect clients and reintroduces unreliability.
+  The correct path to true channel scoping is an upstream library fix.
+- **Knock-on:** idle-disconnect shares the same signal and is likewise
+  server-wide. UI copy in `web/src/views/Settings.vue` was updated to say
+  "服务器" rather than "频道" to match. `cmdVote` was intentionally left on the
+  query path (out of scope; switching it would inherit the same timeout).

+# Dedicated-link bot scoping (+ refresh fix) — design
+
+**Issue:** [#79](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/79) items 2 and 4
+**Date:** 2026-05-30
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Problem
+
+- **Item 2:** A dedicated link (`/bot/:id`) is meant to give someone control of *one* bot, but today it just sets the active bot and bounces to `/`; the user can still switch to any other bot from the top-right selector.
+- **Item 4 (bug):** After opening a dedicated link, refreshing the page loses the bot — the UI falls back to the first bot.
+
+Root cause (verified): `BotRedirect.vue` does `router.replace('/')` (dropping the id), and `activeBotId` is in-memory-only Pinia state with no persistence, so a reload resets it to `bots[0]`.
+
+## Decision (from brainstorm: Q2 = URL-carried scope)
+
+Carry the scoped bot in the **URL query** (`?bot=<id>`). One mechanism fixes **both** items: the URL is durable across refresh (item 4) and shareable/self-clearing, and the frontend locks the selector to the scoped bot (item 2). No localStorage sticky-lock; plain `/` (no `?bot`) = full control. Backend per-bot authorization (PR #80) remains the real boundary — this is a UX lock.
+
+## Design
+
+### Scope state (store)
+Add to the player store:
+- `scopedBotId: string | null` — the bot the UI is locked to.
+- getter `isScoped` = `scopedBotId !== null`.
+- action `setScope(id)` / `clearScope()`.
+- `setActiveBotId(id)` becomes a no-op (or ignores) when `isScoped` and `id !== scopedBotId`, so stray switch attempts can't change bots.
+
+### URL as the durable source of truth
+- `BotRedirect.vue` (`/bot/:id`): instead of `router.replace('/')`, validate the bot exists, then `router.replace({ path: '/', query: { bot: id } })`. (Keeps the "clean" home URL but with `?bot=`.)
+- **Router `beforeEach` guard** (the heart of it):
+  - If `to.query.bot` is present → `store.setScope(to.query.bot)` and continue.
+  - Else if `store.isScoped` (a scope is active and this navigation dropped the param) → redirect to the same route **with** `query.bot = store.scopedBotId` re-attached (so the lock survives in-app navigation to /search, /library, etc.).
+  - Else → no scope; continue.
+  This keeps `?bot=` on the URL for every route while scoped, so a refresh on *any* route re-establishes the lock → **fixes item 4**.
+- On app load / after `fetchBots()`: apply `scopedBotId`/`?bot` to `activeBotId`; if the scoped bot doesn't exist or isn't in the user's allowed set, **clear the scope gracefully** (fall back to normal multi-bot view) rather than locking onto a dead id.
+
+### Exit
+- `clearScope()` sets `scopedBotId = null`; the exit affordance navigates to `/` *after* clearing, so the guard won't re-attach `?bot`. This is the only way to leave scoped mode (self-clearing, intentional).
+
+### Navbar (the lock UI)
+- When `isScoped`: the bot selector shows **only** the scoped bot, the dropdown/switching is disabled (no chevron / non-interactive), and other bots' "copy link" affordances are not shown.
+- Show a small "专属模式" indicator with an "退出" control → `clearScope()` + navigate to `/`.
+- When not scoped: unchanged (full selector over `controllableBots`).
+
+### Active-bot coherence
+Because every player action already routes through `activeBotId`, locking `activeBotId === scopedBotId` guarantees all controls affect only the scoped bot. The store's `activeBot` getter `bots[0]` fallback still degrades safely if the scoped id ever fails to match (combined with the graceful-clear above).
+
+## Components / files
+
+- `web/src/stores/player.ts` — `scopedBotId` state, `isScoped`, `setScope`/`clearScope`, guard in `setActiveBotId`, apply scope→active in `fetchBots`/init (graceful clear if missing).
+- `web/src/router/index.ts` — `beforeEach` scope sync + `?bot` preservation.
+- `web/src/views/BotRedirect.vue` — set scope + `replace({ path: '/', query: { bot: id } })`.
+- `web/src/components/Navbar.vue` — locked selector + "专属模式/退出" affordance.
+- `web/src/App.vue` — ensure scope is applied to `activeBotId` after `fetchBots` on load (if not already handled by the store/guard).
+
+## Testing
+
+Vue UI isn't unit-tested in this repo, so verification is `vue-tsc` + manual run. The **store scope logic is testable** if a lightweight test harness exists for Pinia stores; otherwise assert the pure pieces:
+- `setActiveBotId` ignores a switch to a non-scoped bot while scoped; allows the scoped bot.
+- `clearScope` resets state.
+- A small helper for "resolve scope from query + bots list → {scopedBotId, activeBotId} or cleared-if-missing" can be extracted and unit-tested.
+Manual: open `/bot/<id>` → locked to that bot, selector shows only it; refresh → still locked (item 4 fixed); navigate to Search then refresh → still locked; click 退出 → back to all bots; open `/` directly → full control (no lock).
+
+## Non-goals
+
+- No localStorage persistence (URL is the source of truth). No backend change (per-bot auth already exists in #80). No change to how dedicated links are generated (still `<base>/bot/<id>`); only what happens when one is opened.

+# Guest mode (login-less WebUI access) — design
+
+**Issue:** [#83](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/83) — "请求增加 WebUI 鉴权 guest 登录功能"
+**Date:** 2026-06-24
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Scope
+
+Add an optional, **default-OFF** guest mode. When an admin enables it, anyone who can
+reach the WebUI can enter **without logging in** ("以游客身份进入 / Continue as guest")
+and use a restricted subset of playback/queue features. The admin chooses, per
+deployment, exactly what guests may do (a set of toggles) and which bot(s) guests may
+control. Guests can **never** view or change settings, manage bots, set platform
+credentials, change audio quality, or see the user/audit admin panels.
+
+This builds directly on the existing `admin | member` role + capability system
+(`src/data/permissions.ts`, `requirePermission`, `useSession().can()`) and the existing
+append-vs-play-next queue split (`PlayQueue.add` vs `addNext`). It does **not** rebuild
+auth.
+
+The original issue asked specifically that guest song requests go to "下一首" only.
+That exact behavior is reproducible in this design by the admin turning the
+"add to end" toggle **off** and the "play next" toggle **on** — it is one configuration
+of a more general per-ability toggle model (chosen in brainstorm).
+
+## Problem
+
+Today every `/api/*` route past the session router requires a real account
+(`requireAuth`). There is no anonymous/guest path: to let a friend queue a song, an
+admin must create them a `member` account. The maintainer wants a low-friction,
+admin-gated way to let untrusted visitors request music without an account, while
+keeping all administration locked down.
+
+## Decisions (from brainstorm)
+
+1. **Guest = no-login.** A guest is an **anonymous, config-driven synthetic principal**
+   (`role: "guest"`), not a database user with a password. No favorites, no
+   change-password, short-lived session.
+2. **Default OFF**, enforced **server-side** (the guest-session endpoint rejects when
+   the flag is off — never rely on hiding the button).
+3. **Per-ability toggles**, not a single "mode". Every song action and control action is
+   its own admin switch. Default state when guest mode is first enabled: only
+   "add to end of queue" is ON; everything else OFF.
+4. **Per-bot guest scope** (`"all"` or an explicit bot list), mirroring the existing
+   member bot allow-list. Guests cannot see or control out-of-scope bots — including
+   over WebSocket.
+5. **Settings are always hidden AND server-blocked for guests** (view + change), closing
+   the two currently-ungated reads (`GET /api/bot/settings`, `GET /api/music/quality`).
+6. **"Play now" for guests is non-destructive**: insert-next + skip to it, **never** the
+   existing clear-the-whole-queue `/play-song` behavior.
+7. **One unified authorization gate** encapsulates admin/member/guest logic so the
+   existing member/admin capability system is left behavior-unchanged.
+
+## Guest ability model
+
+### Always allowed (baseline read-only — the point of the feature)
+- Browse/search library, playlists, history, song detail, lyrics, cover art.
+- See now-playing and the live queue (REST + WebSocket), **scoped to allowed bots**.
+
+### Always denied (hard locks — not toggles)
+- View **or** change any settings (idle timeout, auto-pause, theme persistence server-side, command prefix, etc.).
+- Bot management (create/edit/delete/start/stop, bot config, avatar, profile).
+- Music-platform login (`/api/auth/*`), audio quality (`/api/music/quality`).
+- User management (`/api/users`), audit log (`/api/audit`), change-password.
+
+### Admin-configurable toggles (`guestMode.permissions.*`, all default `false` except `addToQueue`)
+
+| Flag | 中文 | Default | Backend route(s) gated |
+|---|---|---|---|
+| `addToQueue` | 添加到队列末尾 | **true** | `POST /:botId/add`, `/add-song`, `/add-by-id` |
+| `playNext` | 添加到下一首 | false | `POST /:botId/play-next-song` |
+| `playNow` | 立即播放（不清空队列） | false | new guest-safe play-now (insert-next + skip) |
+| `skip` | 跳过当前歌曲 | false | `POST /:botId/next` |
+| `transport` | 暂停/继续/进度/音量 | false | `POST /:botId/pause`, `/resume`, `/seek`, `/volume` |
+| `removeClear` | 移除/清空队列 | false | `DELETE /:botId/queue/:index`, `POST /:botId/clear` |
+| `playMode` | 切换播放模式 / FM | false | `POST /:botId/mode`, `/fm` |
+
+Notes:
+- Routes with **no** guest flag (e.g. `/prev`, `/stop`, `/play-song`, `/play-playlist`,
+  `/play-album`, `/play-at`, all of `/api/bot/*`, `/api/auth/*`, settings, users, audit)
+  are **never** reachable by guests — the gate denies any guest without an explicit flag.
+  This is the safe default: new routes are guest-denied unless deliberately opted in.
+- `/play-song`, `/play-playlist`, `/play-album` call `queue.clear()` and must stay
+  guest-denied regardless of toggles (they would wipe everyone's queue).
+
+## Config schema (`src/data/config.ts`)
+
+```ts
+export interface GuestPermissions {
+  addToQueue: boolean;   // append to end
+  playNext: boolean;     // 下一首 (insert after current)
+  playNow: boolean;      // 立即播放: insert-next + skip-to-it (non-destructive)
+  skip: boolean;         // skip current track
+  transport: boolean;    // pause/resume/seek/volume
+  removeClear: boolean;  // remove a queue item / clear the queue
+  playMode: boolean;     // play mode (shuffle/repeat) + FM
+}
+
+export interface GuestModeConfig {
+  enabled: boolean;          // master switch, default false
+  bots: "all" | string[];    // per-bot scope (botIds); default "all"
+  permissions: GuestPermissions;
+}
+
+// added to BotConfig:
+guestMode: GuestModeConfig;
+```
+
+`getDefaultConfig()` returns:
+```ts
+guestMode: {
+  enabled: false,
+  bots: "all",
+  permissions: {
+    addToQueue: true, playNext: false, playNow: false,
+    skip: false, transport: false, removeClear: false, playMode: false,
+  },
+}
+```
+
+**Merge hardening:** `loadConfig` currently does a shallow `{...defaults, ...partial}`,
+which would drop `guestMode` sub-keys if a saved config only contains a partial
+`guestMode`. `loadConfig` must **deep-merge `guestMode`** (and its `permissions`) over
+the defaults so missing sub-keys are back-filled. Covered by a `config.test.ts` case.
+
+**Bot deletion:** when a bot is removed, prune its id from `guestMode.bots` (if it's an
+array) and persist — mirrors `PermissionStore.pruneBot(botId)` for members. Done in the
+same `BotManager.removeBot` path that already prunes member access.
+
+## Backend design
+
+### Synthetic guest principal & session entry
+- **Role union widened** to `"admin" | "member" | "guest"` (`UserRole` in
+  `src/data/users.ts`, the `req.user` augmentation in `requireAuth.ts`, the frontend
+  `User` type, and the role badge in Navbar).
+- **Reserved guest user row.** A single fixed row (e.g. id `"__guest__"`, role `"guest"`,
+  an unusable password hash, username e.g. `"guest"`) is created idempotently by
+  migration. It exists only to satisfy the `sessions.userId` FK and the
+  `validateAndTouch` JOIN; it is excluded from user-management listings and the
+  last-admin guards (those count `role = 'admin'` only, so guests don't interfere).
+- **Guest login endpoint:** `POST /api/session/guest`, mounted in the **public** block
+  (before `csrfOriginCheck`/`requireAuth`, like `/login` and `/setup`), rate-limited.
+  - If `config.guestMode.enabled` is false → `403 guest mode disabled`.
+  - Else `sessions.createSession("__guest__")` and set the same `tsmb_session` httpOnly
+    cookie. **Guest sessions use a short TTL** (e.g. `GUEST_SESSION_TTL_MS`, ~24h) and
+    **bypass `MAX_SESSIONS_PER_USER`** for the guest principal (otherwise guest #11
+    would evict guest #1). Expired guest sessions are already deleted on validation; an
+    optional periodic sweep can prune stale ones.
+- **Disable = logout.** In `createRequireAuth`/`validateSession`, if a validated session
+  has `role === "guest"` but `config.guestMode.enabled` is now false, treat it as
+  unauthenticated (401). So flipping guest mode off immediately ends guest access.
+- **Expose availability:** extend `GET /api/session/needs-setup` (or add a sibling
+  `GET /api/session/guest-config`) to return `guestAllowed: boolean` so the **public**
+  Login page can decide whether to show the guest button. This must not leak any other
+  config.
+
+### Permission resolution
+`resolvePermissionContext` gains a `guest` branch. Signature extended to receive the
+live guest config:
+```ts
+resolvePermissionContext(role, userId, store, guestConfig?) => {
+  admin  → { capabilities: all CAPABILITIES, bots: "all" }
+  member → stored caps + stored bots            // unchanged
+  guest  → {
+    capabilities: new Set(),                     // holds NO member capabilities
+    bots: guestConfig.bots === "all" ? "all" : new Set(guestConfig.bots),
+    guest: guestConfig.permissions,              // resolved per-request from live config
+  }
+}
+```
+`PermissionContext` and `req.user` gain an optional `guest?: GuestPermissions`. Because
+`req.user` is rebuilt per request, toggling a permission or the bot scope takes effect on
+the guest's next request (no re-login).
+
+### Unified authorization gate (`src/web/middleware/authorize.ts`, new)
+Replaces `requirePermission('x')` on **guest-reachable** routes:
+```ts
+authorize({ capability?: Capability, guestFlag?: keyof GuestPermissions })
+  // 401 if no req.user
+  // admin  → next()
+  // guest  → (req.user.guest?.[guestFlag] === true) ? next() : 403   // also 403 if no guestFlag
+  // member → (capability && req.user.capabilities.has(capability)) ? next() : 403
+```
+- Member/admin semantics are **identical** to today's `requirePermission`.
+- A route with no `guestFlag` is automatically guest-denied (safe default).
+- `requireBotAccess` is unchanged and already enforces the guest `bots` scope (guests
+  flow through `req.user.bots`).
+- `requireAdmin` is unchanged (guests are non-admin → 403), so `/api/users` and
+  `/api/audit` stay locked.
+
+### Route changes (`src/web/api/player.ts`, `bot.ts`, `music.ts`)
+- Re-express guest-reachable player routes via `authorize({ capability, guestFlag })`:
+  - `/add`, `/add-song`, `/add-by-id` → `{ capability: "player.queue", guestFlag: "addToQueue" }`
+  - `/play-next-song` → `{ capability: "player.control", guestFlag: "playNext" }`
+    (members keep `player.control`; guests pass only via `playNext`)
+  - new guest-safe **play-now** → `{ capability: "player.control", guestFlag: "playNow" }`
+  - `/next` → `{ capability: "player.control", guestFlag: "skip" }`
+  - `/pause`,`/resume`,`/seek`,`/volume` → `{ capability: "player.control", guestFlag: "transport" }`
+  - `DELETE /queue/:index`, `/clear` → `{ capability: "player.queue", guestFlag: "removeClear" }`
+  - `/mode`, `/fm` → `{ capability: "player.control", guestFlag: "playMode" }`
+  - everything else stays `authorize({ capability })` (no guest flag) → guest-denied.
+- **Guest-safe play-now**: a new behavior (own route, e.g. `POST /:botId/play-now`, or a
+  `mode:"now"` branch) that does `queue.addNext(song)` then advances to it (skip into the
+  inserted track) — **no `queue.clear()`**. Members/admins may also use it; the existing
+  destructive `/play-song` stays for the normal ▶ in non-guest UI. Exact wiring decided
+  in the plan.
+- **Close ungated reads against guests:** `GET /api/bot/settings` and
+  `GET /api/music/quality` currently have no guard, so a guest could read config. Add a
+  small `requireNotGuest` guard (allow `admin` + `member`, deny `guest` → 403). This
+  **does not change member/admin behavior** — members keep their current read access; only
+  guests are newly denied. (Deliberately not a new member capability, to avoid touching
+  member semantics.)
+
+### WebSocket (`src/web/websocket.ts`, `src/web/server.ts`)
+- Guests authenticate over the WS upgrade unchanged (session cookie). 
+- **Add per-client bot-scope filtering** for guests: the upgrade handler already stamps
+  `ws.userId`; also resolve and stamp the client's bot scope (`"all"` or a Set). In
+  `setupWebSocket`, when sending `init` and broadcasting `stateChange` /
+  `botConnected/Disconnected/Removed`, **filter to bots the client may see**. For guests
+  with a scoped `bots` list, out-of-scope bots are omitted. Admin/member payloads are
+  unchanged (they resolve to `"all"` or their existing member scope — to avoid changing
+  member behavior, filtering may be applied **only when the client is a guest**; decided
+  in the plan).
+
+### Settings write (`POST /api/bot/settings`)
+Extend the existing settings writer (today only idle-timeout + auto-pause) to also accept
+and persist the `guestMode` block (admin-only via `bot.manage`/`requireAdmin`), calling
+`saveConfig`. Live effect: subsequent guest requests read the updated in-memory config.
+
+## Frontend design
+
+- **`useSession.ts`**: extend `User` with `role:'guest'` and a `guest?: GuestPermissions`
+  field (from `/api/session/me`). Add `isGuest` computed and `guestCan(flag)`; make `can`
+  guest-aware where it maps cleanly, but UI gating for guest-specific actions uses
+  `guestCan('addToQueue' | 'playNext' | ...)`. `canControlBot` already enforces the bot
+  scope and works for guests via the `bots` field.
+- **Login page (`Login.vue`)**: when `guestAllowed`, show a prominent
+  "以游客身份进入 / Continue as guest" button calling a new `session.continueAsGuest()`
+  → `POST /api/session/guest` → refresh → redirect to `?next` or home.
+- **Router (`web/src/router/index.ts`)**: in the global `beforeEach`, block guests from
+  `/settings` and `/setup` (redirect to home). Default-off ⇒ when not a guest, behavior
+  is unchanged.
+- **Navbar (`Navbar.vue`)**: hide the settings cog for guests; add a `游客` role badge
+  branch; the bot selector already filters via `canControlBot`, so scoped guests only see
+  allowed bots.
+- **App shell (`App.vue`)**: hide the mobile `/settings` tab for guests; the mini-player
+  transport reduces to the guest's allowed actions.
+- **SongCard / Queue / Player**: gate each action button by the matching `guestCan(flag)`
+  (e.g. show ▶/下一首/添加 per `playNow`/`playNext`/`addToQueue`; show skip/transport/
+  remove/clear/mode per their flags). Buttons a guest lacks are hidden, mirroring how
+  `Queue.vue` already gates on `can('player.queue')` / `can('player.control')`.
+- **Settings → Guest mode admin section (`Settings.vue`)**: new admin-only panel: a
+  master enable switch, the 7 permission checkboxes (with 中文 labels), and a bot scope
+  control (an "全部机器人 / all bots" toggle + per-bot checkboxes) reusing the existing
+  member permission-editor bot allow-list UI. Saving calls `POST /api/bot/settings` with
+  the `guestMode` block.
+
+## Defaults, migration & backward-compat
+
+- `getDefaultConfig().guestMode.enabled = false` ⇒ **no behavior change** on upgrade;
+  existing installs see nothing until an admin opts in.
+- Migration adds the reserved `__guest__` user row idempotently (guarded like the
+  existing `backfillMemberPermissions` `schema_meta` marker) and does **not** grant it
+  any `user_permissions` (guest authorization is config-driven, not row-driven).
+- `loadConfig` deep-merges `guestMode` so older config files gain the new block with
+  defaults.
+- Member/admin flows, capabilities, and the backfill are untouched.
+
+## Testing (TDD)
+
+- **Config**: `getDefaultConfig` includes `guestMode` default-off; `loadConfig`
+  deep-merges a partial `guestMode` (missing sub-keys back-filled); round-trips through
+  `saveConfig`.
+- **`resolvePermissionContext` guest branch**: empty member capabilities; `bots` `"all"`
+  vs scoped Set; `guest` permissions object passthrough.
+- **`authorize` gate**: admin bypass; member has/lacks capability → 200/403 (regression
+  parity with `requirePermission`); guest allowed only when the specific flag is true;
+  guest with no flag on a route → 403; guest on settings reads → 403.
+- **Enforcement (mirror `permissions-enforcement.test.ts`)**: each toggle independently
+  opens exactly its route(s) for a guest and nothing else; `/play-song`/`/play-playlist`/
+  `/play-album` always 403 for guests; per-bot scope: guest 403 on out-of-scope `:botId`.
+- **Session entry**: `POST /api/session/guest` → 403 when disabled, mints guest session
+  when enabled; guest session bypasses `MAX_SESSIONS_PER_USER`; disabling guest mode
+  invalidates existing guest sessions (401); guest TTL shorter than member TTL.
+- **WS scope**: guest receives only in-scope bots' `init`/`stateChange`; reject upgrade
+  unchanged for no cookie.
+- **Frontend** (where covered): `guestCan` gating; router blocks `/settings` for guests.
+
+## Non-goals (YAGNI)
+
+- No guest accounts/usernames, passwords, favorites, or persistence per guest.
+- No per-guest individual identity or rate-limiting beyond the existing IP rate limits
+  (a basic abuse guard on `/api/session/guest` is in; richer abuse controls are future).
+- No change to the `admin | member` capability semantics; guest is an additive,
+  config-driven third principal.
+- No chat-command (TeamSpeak `!add`/`!playnext`) changes — guest mode is **WebUI-only**
+  (the issue is explicitly about WebUI 鉴权).
+- Per-guest bot scoping beyond a single shared guest scope is out of scope (one guest
+  scope applies to all guests).

+# TeamSpeak chat-command permission control — design
+
+**Origin:** User request — "给 ts 命令也加上权限控制" (give the TS chat commands permission control too, like the WebUI already has). Completes the unused `adminGroups` scaffold the original authors left behind.
+**Date:** 2026-06-25
+**Status:** Approved (brainstorm), pending implementation plan
+
+## Scope
+
+Add permission control to **TeamSpeak chat commands** (`!play`, `!add`, `!stop`, …). Today any client in a channel with the bot can run any command; only the WebUI path is permission-gated. This adds a **binary admin gate** keyed on the sender's **TS server groups**: a fixed set of "admin" commands may be restricted to members of configured admin server-groups, while all other commands stay public. Enforcement is **opt-in and backward-compatible** — it activates only once an admin lists their server-group ID(s).
+
+The privileged server-groups are configured in `config.adminGroups` (already declared, currently unused) and become editable from the WebUI.
+
+## Problem
+
+`src/bot/commands.ts` already declares `PUBLIC_COMMANDS` / `ADMIN_COMMANDS` sets and an `isAdminCommand()` helper, and `src/bot/instance.ts:325` has the stub `// TODO: Check if invoker is in adminGroups` — but none of it gates anything. `config.adminGroups: number[]` (`src/data/config.ts:21,46`) is documented as a legacy placeholder and read nowhere. So chat commands are unauthenticated: anyone can `!stop`, `!clear`, `!remove`, move the bot, change volume/mode. The WebUI, by contrast, gates everything via `authorize()` at the HTTP layer.
+
+`executeCommand` (`instance.ts:351`) is **shared** by the chat handler and the WebUI player router; the WebUI gates at the HTTP layer, so the chat gate must live in the **chat handler**, never inside `executeCommand` (else the already-gated WebUI would be double-gated).
+
+## Decisions (from brainstorm)
+
+1. **Binary admin gate**, not per-group capabilities and not a whole-bot allowlist. Reuses the existing `adminGroups` scaffold.
+2. **Admin command set (fixed, one source of truth):** `stop`, `clear`, `remove`, `move`, `vol`, `mode`. Everything else is public. The set lives in one constant so reclassifying a command is a one-line change.
+3. **Default = open / opt-in (backward-compatible):** when `config.adminGroups` is empty (the default), there is **no enforcement** — admin commands stay open to everyone, exactly as today. Enforcement turns on only when `adminGroups` is non-empty.
+4. **Identity key = TS server groups**, matched against `adminGroups`.
+5. **Fail-closed on undeterminable groups:** if an admin command arrives, enforcement is on, and the sender's groups cannot be determined (even after a fallback lookup), **deny**.
+6. **Reply on deny:** the bot sends the sender a brief permission-denied message (silent denial is confusing; the bot already replies to commands).
+7. **Config surface:** `adminGroups` becomes editable from an admin-only WebUI Settings section, live-applied via the existing `/api/bot/settings` endpoint; `config.json` continues to work.
+
+## Permission model
+
+Tier definitions live in `src/bot/commands.ts` (repurpose the existing dead sets; the admin set is the source of truth):
+- **Admin commands:** `stop`, `clear`, `remove`, `move`, `vol`, `mode`.
+- **Public commands:** all others (`play`, `add`, `playnext`/`pn`, `skip`/`next`, `prev`, `pause`, `resume`, `now`, `queue`/`list`, `lyrics`, `vote`, `help`, `search`/`find`, `playlist`, `album`, `artist`, `fm`).
+
+**Enforcement rule** — a command is **allowed** iff:
+1. it is a public command, **OR**
+2. `config.adminGroups` is empty (enforcement off), **OR**
+3. the sender's server groups ∩ `config.adminGroups` ≠ ∅.
+
+Otherwise it is **denied** (no execution; a denial reply is sent).
+
+Expressed as a pure, unit-testable helper (no TS/async dependency):
+```ts
+// returns true = allowed, false = denied
+function canRunCommand(
+  commandName: string,
+  invokerGroups: readonly (string | number)[],
+  adminGroups: readonly number[]
+): boolean
+```
+- not an admin command → `true`.
+- admin command, `adminGroups.length === 0` → `true` (enforcement off).
+- admin command, non-empty `adminGroups` → `true` iff any `invokerGroups` value (normalized to number/string consistently) is in `adminGroups`, else `false`.
+
+> Note: `invokerGroups` from TS are strings; `adminGroups` are numbers. Normalize both sides (compare as the same type) to avoid `"6" !== 6` bugs.
+
+## Identity resolution
+
+The TS library already delivers the sender's server groups on each chat event (`TextMessage.invokerGroups: string[]` in `@honeybbq/teamspeak-client`), but the wrapper type `TS3TextMessage` (`src/ts-protocol/client.ts:58-64`) and its mapping (`client.ts:205-214`) **drop** it.
+
+Changes:
+1. Add `invokerGroups: string[]` to `TS3TextMessage` and populate it from `msg.invokerGroups` in the mapping.
+2. **Availability caveat:** `invokerGroups` is populated only when the sender's client is in the bot's local cache (typically same channel / in view). For a private message from an unseen client, it is `[]`.
+3. **Fallback lookup (only when needed):** in the gate, if the command is admin-gated **and** enforcement is on **and** `invokerGroups` is empty, perform a targeted lookup of the sender's groups keyed on `invokerId` (clid) — reuse the already-wrapped `getClientsInChannel()` (`client.ts:314-323`, whose `ClientInfo` carries `serverGroups`), or add a thin wrapper around the library's `getClientInfo(client, clid)` for a precise `clientinfo` query. This query is skipped entirely for public commands, when enforcement is off, and when the event already carried groups (the common "listener in the channel types `!stop`" case).
+4. **Fail-closed:** if after the fallback the groups are still unknown, deny the admin command.
+
+## Enforcement seam
+
+In `handleTextMessage` (`src/bot/instance.ts:317`), replace the dead stub at `instance.ts:325-327` with the real check, placed after `parseCommand` succeeds and **before** `executeCommand` (`instance.ts:335`):
+- compute `allowed` via `canRunCommand(parsed.name, msg.invokerGroups, this.config.adminGroups)`, performing the async fallback lookup only when the synchronous check is "deny due to empty groups on an admin command with enforcement on";
+- if denied → send the denial reply to `msg` (respecting its `targetMode`/sender) and return without executing;
+- if allowed → `executeCommand(parsed, msg)` as today.
+
+`executeCommand` stays permission-agnostic, so the WebUI path is unaffected.
+
+**Live config:** `BotInstance` already holds the shared `config` object by reference (passed through `BotInstanceOptions`); `POST /api/bot/settings` mutates that same object in place, so reading `this.config.adminGroups` in the gate reflects edits immediately — no restart, no re-wiring. (Implementation must confirm the instance reads `adminGroups` from the live `config` reference, not a copied-at-construction value.)
+
+## Denied UX
+
+The bot replies to the sender with a short bilingual-ish message, e.g. `⛔ 需要管理员权限（该命令仅限管理员服务器组）`, via the same reply mechanism the command handlers already use, honoring the message's `targetMode` (private vs channel). No execution occurs.
+
+## Config surface
+
+**Backend** (`src/web/api/bot.ts`): extend the existing settings endpoints (already admin-gated: `GET` behind `requireNotGuest`, `POST` behind `requirePermission("bot.manage")`):
+- `GET /api/bot/settings` → also return `adminGroups: number[]`.
+- `POST /api/bot/settings` → also accept `adminGroups`; validate it is an array of non-negative integers (filter/reject otherwise), assign to `config.adminGroups`, `saveConfig`. Reuses the in-place-mutation + `saveConfig` pattern already used for idle-timeout/auto-pause/guestMode, so it is live-applied.
+
+**Frontend** (`web/src/views/Settings.vue`): a new admin-only section **"命令权限 / Command permissions"** (`v-if="session.isAdmin.value"`), mirroring the idle-timeout/guest-mode sections:
+- a text input for comma-separated server-group IDs (parsed to `number[]`, ignoring blanks/non-numbers), a Save button calling `POST /api/bot/settings`, hydrated by the existing `loadIdleTimeout()` GET;
+- hint: "仅这些组可运行 stop/clear/remove/move/vol/mode；留空 = 不限制（所有人可用）。如何查看服务器组 ID 见 README。"
+
+**`config.json`**: `adminGroups` continues to work for file-based config.
+
+## Testing
+
+- **`canRunCommand` unit tests** (`src/bot/commands.test.ts` or a new file): public command always allowed; admin command with empty `adminGroups` allowed; admin command with a matching group allowed; admin command with no matching group denied; string-vs-number normalization (`["6"]` matches `[6]`).
+- **Handler gate tests:** a denied admin command does NOT call `executeCommand` and triggers a denial reply; an allowed admin command (matching group) and any public command DO call `executeCommand`. (Use a fake `msg` + a `config` with `adminGroups` set; stub the reply + `executeCommand`.)
+- **Fallback path:** admin command with empty `invokerGroups` + enforcement on triggers the group lookup; if the lookup yields a matching group → allowed; if it yields nothing → denied (fail-closed).
+- **Settings round-trip** (`src/web/api/bot.test.ts`): `POST /api/bot/settings` persists a validated `adminGroups`; `GET` returns it; invalid values (non-array, negative, non-integer) are rejected/filtered.
+- **Frontend:** `vue-tsc --noEmit` clean.
+
+## Non-goals (YAGNI)
+
+- No per-group capability map and no whole-bot allowlist (binary admin gate only).
+- No per-command customization of the admin/public split in the UI (the set is a code constant; reclassifying is a one-line edit).
+- No server-group picker UI (admin types IDs; a picker that lists the bot's visible groups is a possible future enhancement).
+- No new chat *management* commands.
+- No change to the WebUI authorization model or `executeCommand` semantics.

+"""Open a real Chromium browser at y.qq.com, let the user log in via any
+method (password / QR / QQ connect), then extract the resulting cookie
+set and save it to data/cookies/qq.json. Also tests whether the cookie
+actually unlocks a known VIP track (Jay Chou 稻香) against the local
+QQ Music API before declaring success.
+
+Usage:
+    "C:/Users/saopig1/miniforge3/python.exe" scripts/qq_browser_login.py
+
+Steps:
+    1. A visible Chromium window opens at y.qq.com/n/ryqq/player
+    2. Click the login button in the top right and log in with your
+       real QQ Music account (the one that has VIP)
+    3. The script POLLS cookies in the background and auto-detects
+       successful login by watching for the `uin` cookie to appear
+    4. Once detected, cookies are captured, tested against
+       /getMusicPlay for 稻香, and saved on success
+    5. If VIP still fails, cookies are NOT saved — your existing bot
+       cookie stays untouched
+
+No terminal input required — the script exits on its own when login
+is detected (or after the configured timeout).

+"""Regression for the 'connected=False but playing=True' stuck-state bug.
+
+After rapid disconnect/reconnect, the library could drop the connection
+(TS3 server anti-flood or a hung handshake). The bot then ended up in an
+inconsistent state: player.state='playing' but tsClient disconnected.
+
+This test verifies three fixes:
+  Bug A — startBot() has a 15s timeout instead of hanging forever on a
+          stalled handshake. /start returns a clean 500 instead of blocking.
+  Bug B — play/add/etc commands are rejected when the bot is not connected.
+  Bug C — the tsClient 'disconnected' handler always clears player state,
+          even when connect() never completed (so !this.connected).
+
+We also sanity-check that the bot recovers (can start a fresh cycle) after
+a transient failure.
