feat: make Jellyfin an optional source instead of the default

Revert the jellyfin-only default introduced by PR #123 so upgrading users keep their online sources; Jellyfin becomes opt-in: - default enabledProviders is now the online set (netease/qq/bilibili/ youtube/kugou); defaultPlatform() uses a fixed priority order (netease -> qq -> kugou -> jellyfin -> bilibili -> youtube) instead of jellyfin-first, so chat/REST/WebUI default to netease again - Settings: Jellyfin card is always visible with a new enable toggle (its enabled bit is enabledProviders membership); guards against clobbering other providers before the list loads - Setup wizard: saving the Jellyfin step auto-enables the source when a server URL was entered - Search/player store fallbacks flip from jellyfin to netease; !help no longer hardcodes Jellyfin lines - tests: update default-platform assertions, add coverage for the new default set, legacy configs without enabledProviders, priority order, and explicit jellyfin-only configs - README: reframe Jellyfin as optional (badges, command table, quality tiers, dedicated section, changelog), document the enabledProviders default and the v1.10.0 jellyfin-only window fix, credit @ItsEricRao Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

+## 可选：Jellyfin 音源
+
+本项目可将自建 [Jellyfin](https://jellyfin.org/) 媒体服务器作为**额外音源**：机器人直接播放你自己音乐库里的文件，不依赖任何在线平台的可用性 / 版权 / 登录状态。该音源**默认关闭**，需要手动启用。
+
+### 启用与连接配置
+
+三种方式任选：
+
+1. **首次安装向导** — 第 3 步即 Jellyfin 连接卡（可跳过，稍后配置）；填写并「保存并继续」会**自动启用**该音源。
+2. **WebUI** — 设置 → Jellyfin 音乐库（可选）：打开「**启用 Jellyfin 音源**」开关，填写服务器地址、选择认证方式、「测试连接」验证后保存，**保存即时生效，无需重启**。
+3. **config.json** — 手动编辑 `jellyfin` 配置块，并把 `"jellyfin"` 加入 `enabledProviders`，然后重启。
+
+两种认证方式：
+
+| 模式 | 填写内容 | 说明 |
+|------|---------|------|
+| **账号密码**（默认） | `username` + `password` | 以该用户身份登录（`AuthenticateByName`），token 自动持久化、失效自动重登 |
+| **API Key** | `apiKey` + `userId` | 使用管理后台生成的 API Key；`userId` 决定使用谁的音乐库 / 收藏 / 歌单 |
+
+```jsonc
+// config.json 片段
+{
+  "jellyfin": {
+    "serverUrl": "https://jellyfin.example.com",

+
+- **搜索** — 歌曲 / 专辑 / 歌单，支持翻页「加载更多」；WebUI 统一搜索中 Jellyfin 结果排最前
+- **播放** — 懒解析播放地址；默认**原始直传**（不经 Jellyfin 转码），也可选 320/192/128kbps 服务器转码档（设置 → 音质设置）
+- **歌词** — 读取 Jellyfin 的歌词接口（内嵌或 .lrc），时间轴同步滚动，`!lyrics` 可用
+- **电台 / FM**（`!fm -j` 或首页「Jellyfin 电台」卡片）— 随机取一首**收藏**做种子生成 Instant Mix 歌曲流；没有收藏则回退到最近播放、再回退随机曲目
+- **首页区块** — 最近添加（专辑）/ 播放最多 / Jellyfin 收藏 / 我的歌单 / 流派（点流派芯片即播放该流派）
+- **播放上报** — 播放开始 / 进度（约 10s 一次）/ 停止会回报给 Jellyfin（`Sessions/Playing` 系列接口），你的 Jellyfin 播放统计（PlayCount、最近播放）保持准确；上报失败不影响播放
+- **聊天命令** — 启用后用 `-j` 标志：`!play -j <歌名>`、`!fm -j`、`!artist -j <歌手>`；`!playlist` / `!album` / `!play id:` 可直接粘贴 Jellyfin GUID。若把在线音源全部停用、只保留 Jellyfin，不带标志的命令会自动以 Jellyfin 为默认音源
+
+### enabledProviders：音源开关
+
+`config.json` 的 `enabledProviders` 数组决定哪些音源可用（默认 `["netease", "qq", "bilibili", "youtube", "kugou"]`，即在线音源全开、Jellyfin 关闭）：
+
+- 可选值：`jellyfin`、`netease`、`qq`、`bilibili`、`youtube`、`kugou`（`local` 由 `localAudioEnabled` 控制，`spotify` 由 `spotify.enabled` 控制）
+- 未列出的音源：聊天命令返回「音源未启用」、REST 返回 400、WebUI 搜索栏 / 登录卡 / FM 卡片自动隐藏
+- 不带平台标志的命令走**固定优先级中第一个已启用的音源**：网易云 → QQ → 酷狗 → Jellyfin → B站 → YouTube（默认配置下即网易云）
+- 网易云 / QQ 停用时，其内嵌 API 服务（端口 3001 / 3200）**不会启动**
+- 示例（Jellyfin 为主、只留网易云备用）：`"enabledProviders": ["jellyfin", "netease"]`（此时默认音源仍为网易云，点歌用 `-j` 或停用网易云）；示例（纯 Jellyfin）：`"enabledProviders": ["jellyfin"]`
+- 注意：重新启用网易云 / QQ 的内嵌 API 服务需要重启机器人；其余音源改动即时生效（WebUI 的 Jellyfin 开关即改此列表）
+
 ## 可选：YouTube 音源

 YouTube 是**可选**的音源，默认**未启用**，需要安装 [yt-dlp](https://github.com/yt-dlp/yt-dlp) 才能使用。启用后可通过聊天命令 `!play -y <关键词>` 或 WebUI 的 YouTube 平台选项搜索/播放 YouTube 视频的音频流。

+# Jellyfin 音源（主音源化）实施计划
+
+目标：自建 Jellyfin 服务器成为默认且主要的音源；现有 NetEase / QQ / Bilibili / YouTube / Kugou
+继续编译但默认停用（`enabledProviders` 配置门控，本次不删除）。约束：`src/audio/*`、
+`src/ts-protocol/*` 不改（唯一例外：`queue.ts` 中 `QueuedSong.platform` 联合类型加一个成员，
+纯类型加宽，无任何逻辑改动，否则无法编译）。
+
+## 触点地图
+
+后端：
+- `src/music/provider.ts` — platform 联合类型加 `"jellyfin"`（Song/Playlist/Album/MusicProvider）
+- `src/audio/queue.ts` — 同上（仅类型，一个词）
+- `src/data/database.ts` — PlayHistoryRecord.platform 加 `"jellyfin"`
+- `src/music/auth.ts` — CookieStore 平台加 `"jellyfin"`（token JSON 与 cookie 同路径持久化）
+- `src/data/config.ts` — 新增 `JellyfinConfig`（serverUrl / authMode / username / password /
+  apiKey / userId）+ `enabledProviders`（默认 `["jellyfin"]`）+ 载入清洗 + `isProviderEnabled` /
+  `defaultPlatform` 助手。spotify 仍由 `spotify.enabled` 门控、local 仍由 `localAudioEnabled` 门控
+- `src/music/jellyfin.ts` — 新 Provider：认证（userpass=AuthenticateByName + MediaBrowser 头，

+  懒解析播放 URL（direct=`/Audio/{id}/stream?static=true`；320/192/128=`/Audio/{id}/universal`
+  转码）、歌单/专辑/歌词（ticks→秒，404=无歌词）、收藏→InstantMix 电台链（收藏→最近播放→随机曲目）、
+  最近添加/最多播放/流派、播放上报（Sessions/Playing[/Progress|/Stopped]，全部吞错）、
+  音质档（direct 原始直传 / 320k / 192k / 128k）

+- `stores/player.ts` — Source 加 jellyfin、enabledProviders 状态、jellyfin 首页数据
+- `views/Search.vue` — 音源条只显示启用的 provider、Jellyfin 徽标
+- `views/Home.vue` — 最近添加 / 播放最多 / 我的歌单 / 收藏 / 流派 区块 + jellyfin FM 卡片
+- `views/Settings.vue` — Jellyfin 连接卡（地址/认证模式/凭据/测试连接）、隐藏停用 provider 的

+- `views/Setup.vue` — 向导第 3 步换成 Jellyfin 连接卡
+- `views/Playlist.vue` 等 — ID 均按 string 处理，审计通过（GUID 无数字假设）

saopig1andClaude Fable 5	750ad9b1cc	feat: make Jellyfin an optional source instead of the default Revert the jellyfin-only default introduced by PR #123 so upgrading users keep their online sources; Jellyfin becomes opt-in: - default enabledProviders is now the online set (netease/qq/bilibili/ youtube/kugou); defaultPlatform() uses a fixed priority order (netease -> qq -> kugou -> jellyfin -> bilibili -> youtube) instead of jellyfin-first, so chat/REST/WebUI default to netease again - Settings: Jellyfin card is always visible with a new enable toggle (its enabled bit is enabledProviders membership); guards against clobbering other providers before the list loads - Setup wizard: saving the Jellyfin step auto-enables the source when a server URL was entered - Search/player store fallbacks flip from jellyfin to netease; !help no longer hardcodes Jellyfin lines - tests: update default-platform assertions, add coverage for the new default set, legacy configs without enabledProviders, priority order, and explicit jellyfin-only configs - README: reframe Jellyfin as optional (badges, command table, quality tiers, dedicated section, changelog), document the enabledProviders default and the v1.10.0 jellyfin-only window fix, credit @ItsEricRao Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 00:54:34 +08:00
