 > **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。
+
+**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)。
+
+**旧版 `config.adminPassword` / `adminGroups`**：这两个配置项在旧版本中预留但从未实际启用（TS-side admin 命令权限的占位字段）。保留以避免破坏旧 `config.json`，但不再影响任何行为。可以放心忽略。

 ## 常见问题
 
 **Q：支持 TeamSpeak 6 Server 吗？**
@@ -459,6 +527,21 @@ A：YouTube 是可选音源，需要手动安装 `yt-dlp`。详见 [可选：You
 **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**不能**：管理其他用户、查看操作审计日志、降级或删除管理员。
+
+**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)）。

+# 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(() => {});

+  } 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
+```
+
+Expected: exit code 0, no output.
+
+Then verify the web project also type-checks:
+
+```
+cd web && npx vue-tsc --noEmit && cd ..
+```
+
+Expected: exit code 0, no output.
+
+- [ ] **Step 1.3: Commit**
+
+```
+git add web/src/components/SourceTabs.vue
+git commit -m "feat(web): add SourceTabs component for platform switcher
+
+Presentational component for switching between netease and qq music
+sources. Auto-hides when fewer than 2 sources are passed in. Mobile
+breakpoint enlarges touch target to 36px.
+
+Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"
+```
+
+---
+
+## 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' } }),
+            axios.get('/api/music/recommend/songs',     { params: { platform: 'qq' } }),
+            axios.get('/api/music/user/playlists',      { params: { platform: 'qq' } }),
+          ]
+        : [
+            Promise.resolve(emptyPlaylists),
+            Promise.resolve(emptySongs),
+            Promise.resolve(emptyPlaylists),
+          ];
+
+      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 (qqRecPL.status === 'fulfilled') {
+        this.recommendPlaylists.qq = qqRecPL.value.data.playlists ?? [];
+      }
+      if (qqDaily.status === 'fulfilled') {
+        this.dailySongs.qq = qqDaily.value.data.songs ?? [];
+      }
+      if (qqUserPL.status === 'fulfilled') {
+        this.userPlaylists.qq = qqUserPL.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):
+
+```vue
+    <!-- 推荐歌单 -->
+    <section class="section" v-if="store.recommendPlaylists.length > 0">
+      <h2 class="section-title">推荐歌单</h2>
+      <div class="playlist-grid">

+
+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.

+
+## Task 4: Migrate Library.vue and remove dead code
+
+**Files:**
+- Modify: `web/src/views/Library.vue`
+
+- [ ] **Step 4.1: Replace the template**
+
+**Find** the `<template>` block (currently lines 1-64) and **replace the entire template with:**
+
+```vue
+<template>
+  <div class="library-page">
+    <h1 class="page-title">音乐库</h1>
+
+    <!-- 我的歌单 -->
+    <section class="section" v-if="userAvailable.length > 0">

+          @add="store.addToQueue(song.name, song.platform)"
+        />
+      </div>
+    </section>
+
+    <div v-if="!historyLoading && userAvailable.length === 0 && history.length === 0" class="empty-state">

+      <div>登录网易云或QQ音乐后，这里将显示你的歌单和播放记录</div>
+    </div>
+  </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) {

+  }
+
+  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**

+# 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;
+  }
+}
+```
+
+- [ ] **Step 3: Render the sections**
+
+Replace the existing `<div v-else-if="results.length > 0" class="results">` block:
+
+```vue
+    <template v-else-if="songs.length || albums.length || playlists.length">
+      <section v-if="albums.length" class="result-section">
+        <h2 class="section-title">专辑</h2>
+        <div class="card-grid">

+        />
+      </section>
+    </template>
+
+    <div v-else-if="searched" class="empty">未找到相关结果</div>
+```
+
+(Import `CoverArt`: `import CoverArt from '../components/CoverArt.vue';`.)
+
+- [ ] **Step 4: Add minimal styles**
+
+Append to the `<style lang="scss" scoped>` block:
+
+```scss
+.result-section {
+  margin-bottom: 32px;
+  .section-title { font-size: 18px; margin: 0 0 12px; opacity: 0.85; }
+}
+.card-grid {
+  display: grid;
+  grid-template-columns: repeat(auto-fill, minmax(140px, 1fr));
+  gap: 16px;
+}
+.card {
+  display: flex;
+  flex-direction: column;
+  gap: 6px;
+  text-decoration: none;
+  color: inherit;
+  .card-name { font-size: 14px; line-height: 1.3; max-height: 2.6em; overflow: hidden; }
+  .card-sub  { font-size: 12px; opacity: 0.6; }
+}
+```
+
+- [ ] **Step 5: Build + visually verify**
+
+```bash
+cd web && npm run build
+```
+
+Then `npm run dev` → search "周杰伦" → see three sections; click an album card → arrives at `/album/:id` with songs + play-all.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add web/src/views/Search.vue
+git commit -m "feat(web): show album + playlist sections in search"
+```
+
+---
+
+### Task 6: Open PR
+
+- [ ] **Step 1: Push branch**
+
+```bash
+git checkout -b feat/album-search
+git push -u origin feat/album-search
+```
+
+- [ ] **Step 2: Create the PR**
+
+```bash
+gh pr create --title "feat(search): album section + album playback" --body "Closes part of #51 (album half).

+## Summary
+- netease.search() / qq.search() now populate SearchResult.albums
+- /api/music/search/all returns albums + playlists alongside songs
+- 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
+
+🤖 Generated with [Claude Code](https://claude.com/claude-code)"

+
+---
+
+## 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) {

+- [ ] **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'))")

+

+
+- [ ] **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).

+# 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.

+# 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(...)` |

+
+## 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

+## 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。

+# 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.
