+# 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;
+```
+

+
+```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**

+### 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>

+const userAvailable = computed<Source[]>(() => {
+  const s: Source[] = [];
+  if (store.authStatus.netease) s.push('netease');
+  if (store.authStatus.qq) s.push('qq');
+  return s;
+});
+
+// Persisted active source per section.
+const recommendSource = ref<Source>(loadTabSource('home.recommend'));
+const dailySource     = ref<Source>(loadTabSource('home.daily'));
+const userSource      = ref<Source>(loadTabSource('home.user'));
+
+watch(recommendSource, (v) => saveTabSource('home.recommend', v));
+watch(dailySource,     (v) => saveTabSource('home.daily',     v));
+watch(userSource,      (v) => saveTabSource('home.user',      v));
+
+// Fallback when persisted source is no longer available (e.g. user logged
+// out of QQ since last visit). We render against `*Safe` but never write
+// back, so the user's preference is preserved for when they log in again.
+const recommendSourceSafe = computed<Source>(() =>
+  recommendAvailable.value.includes(recommendSource.value)
+    ? recommendSource.value
+    : recommendAvailable.value[0] ?? 'netease'
+);
+const dailySourceSafe = computed<Source>(() =>
+  dailyAvailable.value.includes(dailySource.value)
+    ? dailySource.value
+    : dailyAvailable.value[0] ?? 'netease'
+);
+const userSourceSafe = computed<Source>(() =>
+  userAvailable.value.includes(userSource.value)
+    ? userSource.value
+    : userAvailable.value[0] ?? 'netease'
+);
+
+const currentUserPlaylists = computed(() => store.userPlaylists[userSourceSafe.value] ?? []);
+const visibleUserPlaylists = computed(() =>
+  userPlaylistsExpanded.value
+    ? currentUserPlaylists.value
+    : currentUserPlaylists.value.slice(0, USER_PLAYLIST_LIMIT)
+);
+
+async function playFm() {
+  try {
+    const res = await axios.get('/api/music/personal/fm');
+    const songs: Song[] = res.data.songs;
+    if (songs.length > 0) {
+      await store.play(songs[0].name, songs[0].platform);
+      for (let i = 1; i < songs.length; i++) {
+        await store.addToQueue(songs[i].name, songs[i].platform);
+      }
+    }
+  } catch {
+    // Ignore
+  }
+}
+
+onMounted(() => {
+  store.fetchHomeData();
+});
+</script>
+```
+
+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">
+      <h2 class="section-title">
+        我的歌单
+        <span class="section-count">{{ currentUserPlaylists.length }}</span>
+        <SourceTabs v-model="userSource" :sources="userAvailable" />
+      </h2>
+      <div class="playlist-grid">
+        <RouterLink
+          v-for="pl in currentUserPlaylists"
+          :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>
+          <div class="playlist-count">{{ pl.songCount }} 首</div>
+        </RouterLink>
+      </div>
+    </section>
+
+    <!-- 最近播放 -->
+    <section class="section">
+      <h2 class="section-title">最近播放</h2>
+      <div v-if="historyLoading" class="loading">加载中...</div>
+      <div v-else-if="history.length === 0" class="empty">暂无播放记录</div>
+      <div v-else class="song-list">
+        <SongCard
+          v-for="(song, i) in history.slice(0, 10)"
+          :key="`hist-${song.id}-${i}`"
+          :song="song"
+          :index="i + 1"
+          :active="store.currentSong?.id === song.id"
+          @play="store.play(song.name, song.platform)"
+          @add="store.addToQueue(song.name, song.platform)"
+        />
+      </div>
+    </section>
+
+    <div v-if="!historyLoading && userAvailable.length === 0 && history.length === 0" class="empty-state">
+      <Icon icon="mdi:music-box-outline" class="empty-icon" />
+      <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) {
+    await store.fetchBots();
+  }
+
+  store.fetchHomeData();
+
+  if (store.activeBotId) {
+    try {
+      const res = await axios.get(`/api/player/${store.activeBotId}/history`);
+      history.value = res.data.history ?? [];
+    } catch {
+      // API may not be ready
+    }
+  }
+
+  historyLoading.value = false;
+});
+</script>
+```
+
+Changes:
+- Removed `liked` ref and the `/api/music/user/liked` axios call
+- Added auth-driven `userAvailable`, persisted `userSource`, and `currentUserPlaylists` computed
+- Imports `Source` type and `SourceTabs` component
+
+- [ ] **Step 4.3: Style — `.section-title` already supports inline children**
+
+The existing `.section-title` style (Library.vue and Home.vue both) already uses `display: flex; align-items: center; gap: 8px;`. SourceTabs uses `display: inline-flex` with its own `margin-left`, so it sits inline with the title and count. **No style changes are required in either Home.vue or Library.vue.**
+
+---
+
+## Task 5: Verify the build and types
+
+- [ ] **Step 5.1: Run TypeScript backend type check**
+
+```
+npx tsc --noEmit
+```
+
+Expected: exit code 0, no output. (No backend files were touched.)
+
+- [ ] **Step 5.2: Run web type check + production build**
+
+```
+npm run build:web
+```
+
+Expected: build completes with `✓ built in N.NNs` and no TypeScript errors. The script runs `vue-tsc --noEmit && vite build`, so failures here mean a type or template error in our changes.
+
+- [ ] **Step 5.3: Run the existing test suite to confirm no regression**
+
+```
+npm test
+```
+
+Expected: same baseline as before this feature (`Test Files 2 failed | 26 passed (28)`, `Tests 2 failed | 161 passed (163)`). The 2 pre-existing failures are in `dist/` and `.claude/worktrees/` and are unrelated to our changes — they should remain at exactly 2.
+
+If any **source-tree** test fails (anything not in `dist/` or `.claude/worktrees/`), stop and investigate.
+
+---
+
+## Task 6: Manual smoke test on the dev server
+
+This task verifies behavior the type system can't catch.
+
+- [ ] **Step 6.1: Start the dev server**
+
+```
+npm run dev
+```
+
+Wait for `Web server started` and `WebUI: http://localhost:3000` log lines.
+
+- [ ] **Step 6.2: Test scenario A — only NetEase logged in**
+
+Open http://localhost:3000 in a browser. Confirm:
+
+- 推荐歌单 section displays NetEase playlists, **no tab bar visible** (single source, SourceTabs auto-hidden)
+- 每日推荐 section: visible only if NetEase login provides daily songs; **no tab bar**
+- 我的歌单 section: visible if NetEase has user playlists; **no tab bar**
+- Navigate to `/library`: 我的歌单 section: same — no tab bar, NetEase playlists shown
+
+Open DevTools → Application → Local Storage → `localhost:3000` → `source-tabs` should be absent or `{}` (no clicks happened).
+
+- [ ] **Step 6.3: Test scenario B — both NetEase and QQ logged in**
+
+If QQ is not logged in, log in via Settings → QQ Music → 扫码登录.
+
+Hard reload the browser (Cmd/Ctrl+Shift+R) to bypass the 5-min `lastFetchTime` cache.
+
+Confirm:
+
+- 推荐歌单: tab bar shows `[网易云] [QQ]`, NetEase active by default
+- Click `QQ` — playlist grid switches to QQ data, no flicker (data already in store)
+- Click `网易云` — back to NetEase
+- Same for 每日推荐 and 我的歌单
+- Navigate to `/library`, confirm 我的歌单 has its own tab bar with independent state
+- Reload the page — Home tabs and Library tab persist their last-selected source independently
+
+Check `localStorage['source-tabs']`: should contain JSON with up to 4 keys (`home.recommend`, `home.daily`, `home.user`, `library.user`).
+
+- [ ] **Step 6.4: Test scenario C — fallback when persisted source becomes unavailable**
+
+While logged into both:
+1. On Home, switch 推荐歌单 to `QQ`. Confirm `localStorage['source-tabs']['home.recommend'] === 'qq'`.
+2. Go to Settings → log out of QQ.
+3. Hard-reload Home.
+
+Confirm:
+- 推荐歌单 tab bar disappears (only NetEase available)
+- Grid shows NetEase playlists (graceful fallback via `recommendSourceSafe`)
+- `localStorage['source-tabs']['home.recommend']` is **still `'qq'`** (preference preserved)
+4. Log back into QQ → reload → 推荐歌单 grid is QQ again (preference restored)
+
+- [ ] **Step 6.5: Test mobile layout**
+
+Open DevTools → Toggle device toolbar → set width to 375px (iPhone SE).
+
+Confirm on Home and Library:
+- Section title + tab bar fit on the same line without overflow
+- Tab buttons are at least 36px tall (use Inspect → check computed `min-height`)
+- Tabs are tappable (clicking still switches sources)
+
+- [ ] **Step 6.6: Stop the dev server**
+
+Kill the `npm run dev` process.
+
+---
+
+## Task 7: Final commit
+
+- [ ] **Step 7.1: Stage and commit Task 2 + 3 + 4 changes**
+
+```
+git add web/src/stores/player.ts web/src/stores/sourceTabs.ts web/src/views/Home.vue web/src/views/Library.vue
+git status
+```
+
+Expected `git status` output: 4 modified/new files staged, working tree otherwise clean (apart from pre-existing `.claude/worktrees/` and `test-ts6-version.cjs` untracked).
+
+```
+git commit -m "feat(web): per-platform source tabs on Home and Library
+
+Recommend playlists, daily songs, and user playlists on Home now show
+a [网易云][QQ] tab when both platforms are logged in. Library 我的歌单
+gets the same tab. Selection persists per-section in localStorage and
+falls back gracefully when the persisted source becomes unavailable
+(e.g., user logged out). Removes dead 我的收藏 block from Library that
+referenced a non-existent /api/music/user/liked endpoint.

+# 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.
