 ### 最新版本

+**机器人形象自动更新（Bot Profile）**
+
+- **播放时自动更新 TS 形象**：头像（专辑封面缩略图）、昵称（`♪ 歌名 - 歌手 - 原昵称`）、描述（歌曲信息）、Away 状态、频道描述、"正在播放"频道消息，全部随歌曲切换自动更新。
+- **停止播放时恢复默认**：头像清除、昵称恢复、Away 显示"等待播放"、描述和频道描述清空。
+- **权限安全**：每项功能独立检测权限，权限不足时自动禁用该功能（不影响其他功能和播放），重连后重试。
+- **独立可配置**：6 项功能可通过 REST API（`GET/PUT /api/player/:botId/profile`）独立开关，配置持久化到数据库。
+- **竞争条件防护**：generation 计数器防止快速切歌时旧头像覆盖新头像；UTF-8 字节长度截断中文昵称；文件传输操作带超时保护。
+- **TS3 适配**：描述通过 `clientedit`（非 `clientupdate`）设置，需要 `b_client_modify_description` 权限；昵称和 Away 通过合并的单条 `clientupdate` 避免命令队列超时。
+
+**新命令 & FM 修复**
+
+- **新增 `!artist <歌手名>` 命令**：搜索指定歌手的歌曲并循环播放，支持 `-q`（QQ 音乐）/ `-b`（B站）/ `-y`（YouTube）平台切换。一次加载最多 50 首，自动按歌手名过滤并设为 Loop 模式。
+- **歌单模糊搜索**：`!playlist` 现在支持歌单名称模糊搜索（如 `!playlist 华语经典`），自动匹配公开歌单 + 个人歌单（网易云 + QQ）。纯数字 ID 和 URL 解析保持兼容。
+- **修复 `!fm` 播放中断**：私人 FM 几首歌后静音的 bug 已修复。新增自动续播机制（队列低位自动拉取新歌），播放器健康帧追踪防止临时 URL 失败导致永久静音。
+- **QQ 音乐个人歌单**：QQ Music provider 新增 `getUserPlaylists` 支持，登录后可通过 `!playlist -q <名称>` 模糊搜索个人歌单。

+# FM Bug Fix + Artist Loop + Playlist Fuzzy Search — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix FM audio dropout bug, add `!artist` command for artist-based loop playback, and support playlist name fuzzy search in `!playlist`.
+
+**Architecture:** All changes stay within existing files. The FM fix adds auto-refill logic and a success-tracking mechanism in the player. Playlist search reuses the existing `provider.search()` API that already returns playlists. The `!artist` command is a new command method following the same pattern as `cmdPlay`/`cmdFm`.
+
+**Tech Stack:** TypeScript, Node.js, ffmpeg-static, @honeybbq/teamspeak-client

+## File Map
+
+| File | Change | Purpose |
+|------|--------|---------|
+| `src/bot/instance.ts` | Modify | Add `isFmMode`, `refillFm()`, fix `cmdFm()`, modify `cmdPlaylist()`, add `cmdArtist()`, modify `playNext()` to trigger FM refill |
+| `src/bot/commands.ts` | Modify | Register `artist` in PUBLIC_COMMANDS, update help text |
+| `src/audio/player.ts` | Modify | Track healthy frame count, reset `consecutiveFailures` after sustained successful playback |
+
+---
+
+### Task 1: Fix FM — Track healthy playback in AudioPlayer
+
+**Files:**
+- Modify: `src/audio/player.ts:62-82` (add field)
+- Modify: `src/audio/player.ts:243-261` (sendNextFrame — track healthy frames)
+
+- [ ] **Step 1: Add healthy frame counter field**
+
+In `src/audio/player.ts`, after the `consecutiveFailures` field (line ~80), add:
+
+```typescript
+private healthyFrames = 0;
+private static readonly HEALTHY_FRAME_RESET = 50; // ~1 second of audio
+```
+
+- [ ] **Step 2: Track healthy frames and reset failures in sendNextFrame**
+
+In `src/audio/player.ts`, in the `sendNextFrame()` method, after line 257 (`this.framesPlayed++;`), add:
+
+```typescript
+this.healthyFrames++;
+if (this.healthyFrames >= AudioPlayer.HEALTHY_FRAME_RESET) {
+  this.consecutiveFailures = 0;
+  this.healthyFrames = 0;
+}
+```
+
+- [ ] **Step 3: Reset healthyFrames in play() and stop()**
+
+In `play()`, after `this.framesPlayed = 0;` (line ~95), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+In `stop()`, after `this.framesPlayed = 0;` (line ~181), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/audio/player.ts
+git commit -m "fix(player): reset consecutiveFailures after sustained healthy playback"
+```
+
+---
+
+### Task 2: Fix FM — Add auto-refill logic in BotInstance
+
+**Files:**
+- Modify: `src/bot/instance.ts:62-66` (add fields)
+- Modify: `src/bot/instance.ts:557-573` (cmdFm)
+- Modify: `src/bot/instance.ts:642-673` (playNext — add refill trigger)
+
+- [ ] **Step 1: Add isFmMode field**
+
+In `src/bot/instance.ts`, after `private profileManager: BotProfileManager;` (line ~66), add:
+
+```typescript
+private isFmMode = false;
+```
+
+- [ ] **Step 2: Add refillFm method**
+
+In `src/bot/instance.ts`, before the `cmdVote` method (after `cmdFm`'s closing brace), add:
+
+```typescript
+private async refillFm(): Promise<void> {
+  if (!this.isFmMode || !this.neteaseProvider.getPersonalFm) return;
+  try {
+    const songs = await this.neteaseProvider.getPersonalFm();
+    if (songs.length === 0) return;
+    for (const song of songs) {
+      this.queue.add({ ...song, platform: "netease" });
+    }
+    this.logger.debug({ count: songs.length }, "FM queue refilled");
+  } catch (err) {
+    this.logger.error({ err }, "Failed to refill FM queue");
+  }
+}
+```
+
+- [ ] **Step 3: Modify cmdFm to set isFmMode and use RandomLoop**
+
+Replace the existing `cmdFm` method (lines 557-573) with:
+
+```typescript
+private async cmdFm(): Promise<string> {
+  if (!this.neteaseProvider.getPersonalFm) {
+    return "Personal FM is only available for NetEase Cloud Music";
+  }
+  const songs = await this.neteaseProvider.getPersonalFm();
+  if (songs.length === 0)
+    return "No FM songs available (need to login first)";
+
+  this.queue.clear();
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: "netease" });
+  }
+  this.queue.setMode(PlayMode.RandomLoop);
+  this.isFmMode = true;
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Personal FM started: ${first?.name ?? "unknown"} - ${first?.artist ?? ""}`;
+}
+```
+
+- [ ] **Step 4: Modify playNext to trigger FM refill and check isFmMode**
+
+In `playNext()`, replace the `else` branch (lines 665-668) that handles `queue.next() === null`:
+
+```typescript
+} else {
+  // FM mode: try to refill instead of stopping
+  if (this.isFmMode) {
+    await this.refillFm();
+    const refillNext = this.queue.next();
+    if (refillNext) {
+      const started = await this.resolveAndPlay(refillNext);
+      if (!started) {
+        this.player.stop();
+        this.profileManager.onSongChange(null).catch(() => {});
+      }
+      this.emit("stateChange");
+    } else {
+      this.player.stop();
+      this.profileManager.onSongChange(null).catch(() => {});
+    }
+  } else {
+    this.player.stop();
+    this.profileManager.onSongChange(null).catch(() => {});
+  }
+}
+```
+
+Also add a proactive refill after successful advance. At the end of the `if (next)` block, after `this.emit("stateChange");` is handled outside the if/else, add this right after `resolveAndPlay` succeeds (inside the `if (next)` block, after the retry loop):
+
+After the `if (!started)` block and before the closing `}` of `if (next)`, insert:
+
+```typescript
+// Proactive FM refill when running low
+if (this.isFmMode && this.queue.size() - (this.queue.getCurrentIndex()) <= 3) {
+  this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+}
+```
+
+Wait — `this.emit("stateChange")` is outside the `if (next)` block. Let me re-read the original code structure...
+
+The original `playNext()` structure is:
+```
+if (next) {
+    let started = await resolveAndPlay(next)
+    if (!started) { retry loop... }
+    if (!started) { stop }
+} else {
+    stop
+}
+emit("stateChange")
+```
+
+So I need to add the proactive refill inside the `if (next)` block, right after `resolveAndPlay` succeeds. Let me write this more carefully:
+
+```typescript
+private async playNext(): Promise<void> {
+    if (this.isAdvancing || !this.connected) return;
+    this.isAdvancing = true;
+    try {
+      this.voteSkipUsers.clear();
+      const next = this.queue.next();
+      if (next) {
+        let started = await this.resolveAndPlay(next);
+        if (!started) {
+          for (let i = 0; i < 3 && this.connected; i++) {
+            const retry = this.queue.next();
+            if (!retry) break;
+            if (await this.resolveAndPlay(retry)) {
+              started = true;
+              break;
+            }
+          }
+        }
+        if (!started) {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        } else if (this.isFmMode && this.queue.size() - this.queue.getCurrentIndex() <= 3) {
+          // Proactive refill: when queue is running low, fetch more FM songs
+          this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+        }
+      } else {
+        // Queue exhausted — in FM mode, refill instead of stopping
+        if (this.isFmMode) {
+          await this.refillFm();
+          const refillNext = this.queue.next();
+          if (refillNext) {
+            await this.resolveAndPlay(refillNext);
+          } else {
+            this.player.stop();
+            this.profileManager.onSongChange(null).catch(() => {});
+          }
+        } else {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        }
+      }
+      this.emit("stateChange");
+    } finally {
+      this.isAdvancing = false;
+    }
+  }
+```
+
+OK this is getting complex. Let me simplify the plan — I'll structure it more clearly.
+
+Also I need to clear `isFmMode` when user issues stop/clear or manually plays something else.
+
+- [ ] **Step 5: Clear isFmMode in stop/clear/play commands**
+
+In `cmdStop()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdClear()` (same line), add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlay()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlaylist()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdAlbum()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/instance.ts
+git commit -m "fix: FM auto-refill to prevent audio dropout after initial batch"
+```
+

+
+### Task 3: Playlist Fuzzy Search
+
+**Files:**
+- Modify: `src/bot/instance.ts:524-539` (cmdPlaylist)
+
+- [ ] **Step 1: Modify cmdPlaylist to support name search**
+
+Replace the `cmdPlaylist` method (lines 524-539) with:
+
+```typescript
+private async cmdPlaylist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !playlist <playlist name or ID>";
+  const provider = this.getProvider(cmd.flags);
+
+  // Determine if input is a numeric ID or a name search
+  const id = this.extractId(cmd.args);
+  const isNumericId = /^\d+$/.test(cmd.args.trim());
+
+  let playlistId: string;
+
+  if (isNumericId || id !== cmd.args) {
+    // Input is a numeric ID or URL containing an ID — use existing logic
+    playlistId = id;
+  } else {
+    // Name-based search
+    const result = await provider.search(cmd.args);
+    let playlists = result.playlists ?? [];
+
+    // Also search user's personal playlists if logged in
+    if (provider.getUserPlaylists) {
+      try {
+        const userPlaylists = await provider.getUserPlaylists();
+        const query = cmd.args.toLowerCase();
+        const matched = userPlaylists.filter(
+          p => p.name.toLowerCase().includes(query)
+        );
+        // Merge: public results first (API-ranked), then user matches
+        playlists = [...playlists, ...matched];
+      } catch {
+        // User playlists unavailable — continue with public results
+      }
+    }
+
+    if (playlists.length === 0)
+      return `No playlists found for: ${cmd.args}`;
+    playlistId = playlists[0].id;
+  }
+
+  const songs = await provider.getPlaylistSongs(playlistId);
+  if (songs.length === 0) return "Playlist is empty or not found";
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Loaded ${songs.length} songs. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 2: Update help text to reflect new usage**
+
+In `cmdHelp()` (line ~633), change the playlist line from:
+
+```
+`${p}playlist <id> — Load playlist`
+```
+
+to:
+
+```
+`${p}playlist <name or id> — Load playlist by name or ID`
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/bot/instance.ts
+git commit -m "feat: support playlist name fuzzy search in !playlist command"
+```
+
+---
+
+### Task 4: Artist Loop Command
+
+**Files:**
+- Modify: `src/bot/commands.ts:8-11` (PUBLIC_COMMANDS)
+- Modify: `src/bot/commands.ts:248-260` (AUDIO_COMMANDS in instance.ts — actually in instance.ts)
+- Modify: `src/bot/instance.ts:244-314` (executeCommand switch + add cmdArtist)
+
+Wait, AUDIO_COMMANDS is in instance.ts executeCommand. Let me check...
+
+Actually looking back at instance.ts, the AUDIO_COMMANDS set is local to executeCommand. I don't need to add artist there since it will be handled in the switch.
+
+- [ ] **Step 1: Register `artist` in PUBLIC_COMMANDS**
+
+In `src/bot/commands.ts`, line 9, add `"artist"` to the PUBLIC_COMMANDS set:
+
+```typescript
+export const PUBLIC_COMMANDS = new Set([
+  "play", "add", "queue", "list", "now", "lyrics", "vote", "help",
+  "playlist", "album", "fm", "prev", "next", "skip", "pause", "resume",
+  "artist",
+]);
+```
+
+- [ ] **Step 2: Add `artist` to the AUDIO_COMMANDS set in executeCommand**
+
+In `src/bot/instance.ts`, in the `executeCommand` method, add `"artist"` to the AUDIO_COMMANDS set (line ~253):
+
+```typescript
+const AUDIO_COMMANDS = new Set([
+  "play", "add", "next", "skip", "prev", "playlist", "album", "fm",
+  "artist",
+]);
+```
+
+- [ ] **Step 3: Add `artist` case to the switch in executeCommand**
+
+In `src/bot/instance.ts`, after the `case "fm":` block (line ~300), add:
+
+```typescript
+case "artist":
+  return this.cmdArtist(cmd);
+```
+
+- [ ] **Step 4: Implement cmdArtist method**
+
+Add the `cmdArtist` method in `src/bot/instance.ts`, after `cmdFm()`:
+
+```typescript
+private async cmdArtist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !artist <artist name>";
+  const provider = this.getProvider(cmd.flags);
+  const result = await provider.search(cmd.args, 50);
+  if (result.songs.length === 0)
+    return `No results found for artist: ${cmd.args}`;
+
+  const query = cmd.args.toLowerCase();
+  let filtered = result.songs.filter(
+    s => s.artist.toLowerCase().includes(query)
+  );
+
+  // Fallback to unfiltered results if filtering drops everything
+  if (filtered.length === 0) {
+    filtered = result.songs.slice(0, 20);
+  }
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of filtered) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  this.queue.setMode(PlayMode.Loop);
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Artist mode: ${cmd.args} — ${filtered.length} songs loaded. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 5: Update help text**
+
+In `cmdHelp()`, add the artist help line after the fm line:
+
+```
+`${p}artist <name> — Play songs by artist (loop)`
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/commands.ts src/bot/instance.ts
+git commit -m "feat: add !artist command for artist-based loop playback"
+```
+
+---
+
+### Task 5: Type-check and verify
+
+**Files:**
+- All modified files
+
+- [ ] **Step 1: Run type check**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && npm run typecheck
+```
+
+Expected: No errors.
+
+- [ ] **Step 2: Verify command parsing**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && node --loader ts-node/esm -e "
+const { parseCommand } = await import('./src/bot/commands.ts');
+console.log(parseCommand('!artist 周杰伦', '!'));
+console.log(parseCommand('!artist 周杰伦 -q', '!'));
+console.log(parseCommand('!playlist 华语经典', '!'));
+console.log(parseCommand('!playlist 123456', '!'));
+"
+```
+
+Expected: All parse correctly; `artist` with args "周杰伦", `playlist` with args "华语经典" and "123456".
+
+- [ ] **Step 3: Commit any fixes from type check**
+
+```bash
+git add -A && git commit -m "chore: type fixes from final verification"
+```
+(Only if there were issues)
+
+---
+
+### Self-Review Checklist
+
+1. **Spec coverage:**
+   - FM bug fix → Tasks 1, 2 (healthy frame tracking + auto-refill)
+   - Playlist fuzzy search → Task 3
+   - Artist loop → Task 4
+   - Verification → Task 5
+
+2. **No placeholders** — all steps have exact code.

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

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

Claude	314d6ec955	fix(profile): validate TS6 HTTP status and stop escaping JSON body Silent failure: logs showed "Client properties updated" / "Description updated" / "Avatar updated" even though the bot's nickname never changed and the avatar stayed as "loading image" on clients. Root causes: - TS6HttpQuery.clientUpdate ignored non-2xx responses, so 400 (bad parameter) and 403 (insufficient permission) were reported as success. - updateClientProperties built TS3-escaped strings (\\s for space) then split them back into JSON props, so TS6 received literal backslashes and rejected the nickname silently. - handleFeatureError only matched textual "permission" errors; HTTP 4xx statuses weren't recognised and the feature retried every song. - doAvatarUpload had no per-step logging, making it impossible to tell whether a broken avatar came from init, the TCP 30033 transfer, or the client_flag_avatar command. Fixes: - Add HttpQueryError (status/body/path); clientUpdate throws on non-2xx. - Build a raw property map in updateClientProperties; escape only on the TS3 wire path. - Log HTTP status and updated prop names on success. - handleFeatureError now treats HTTP 400/401/403 as unrecoverable. - Debug-log each step of doAvatarUpload plus bytes/elapsedMs on success. https://claude.ai/code/session_018NrpGWbQQTrahUVXyea5Jy	2026-04-17 16:21:52 +00:00

Claude	fecda7cce3	fix(web): make bot-link usable on public IP with HTTP The "复制专属链接" button silently failed on public-IP HTTP deployments because navigator.clipboard requires a secure context. Now the link is always revealed in a modal with a read-only input (select-all on focus), so users can copy manually even when clipboard APIs and execCommand both fail. The dialog still tries to auto-copy when possible. Also adds a publicUrl config option that overrides window.location.origin for link generation (useful behind reverse proxies / with custom domains), exposed via GET /api/config/public-url, and a trustProxy flag so Express honors X-Forwarded-* when fronted by nginx/Caddy/Cloudflare. https://claude.ai/code/session_019FSX3S3UUcKEYWanYmoqUv	2026-04-17 16:08:00 +00:00
saopig1andClaude Opus 4.6	b9e42d543c	fix(web): make bot-link copy work over plain HTTP navigator.clipboard requires a secure context (HTTPS or localhost). For users hosting the bot on a remote IP and accessing via http://<ip>:3000, clipboard.writeText is undefined and the copy silently fails. Add a hidden-textarea + execCommand('copy') fallback, with a final prompt() fallback so the user can always grab the URL.

saopig1andClaude Opus 4.6	da5b34f5f4	feat(profile): auto-update bot avatar, nickname, and away status based on playing song Add BotProfileManager that updates the bot's TeamSpeak presence when songs change: album cover as avatar, song info in nickname, away status toggled on stop/play. Each feature is independently configurable via REST API and persisted to the database. Permission-safe — features that fail due to insufficient server permissions are silently disabled until reconnect. Description falls back to nickname display on TS3 (only supported via TS6 HTTP Query). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-13 00:14:29 +08:00

Claude	e2b1a5e055	fix: prevent skipped/duplicate songs in Random mode edge cases Three corner cases fixed: 1. Removing the currently-playing song caused the next song in the array to be silently marked as "played" and skipped. Root cause: playedIndices was updated in next() by marking currentIndex, but after remove() shifts currentIndex, it pointed to the wrong song. Fix: mark songs as played at play-time (in play/playAt/next/prev) instead of at next-request-time. 2. Using prev() in Random mode could cause a song to play twice — the song navigated to via prev() was not recorded in playedIndices, so next() could randomly select it again. Fix: prev() now marks the returned song as played. 3. Switching to Random mode mid-playback could cause the current song to repeat because setMode() cleared playedIndices without preserving the currently-playing song. Fix: setMode() now re-adds currentIndex after clearing. https://claude.ai/code/session_01W3ZncxL5VfdZeB4qqYWDmY	2026-04-12 15:02:53 +00:00
Claude	4eac2e4dde	fix: Random mode now stops after all songs played instead of looping forever In Random (shuffle) mode, the queue's next() method would return the same song indefinitely when only one song was in the playlist, and never terminate even with multiple songs. This happened because played songs were not tracked. Added a playedIndices Set to track which songs have already been played in Random mode. Once all songs have been played once, next() returns null to stop playback — matching the expected behavior where Random plays each song once in random order, while RandomLoop is the mode for infinite shuffling. https://claude.ai/code/session_01W3ZncxL5VfdZeB4qqYWDmY	2026-04-12 14:53:15 +00:00
