-### 9.2 前端多路流管理 UI **没做**
-- 后端能创建/删除流，但前端只有一个**切换下拉框**（`#streamSelect`），**没有"新建流/删除流"的界面**。
-- 若用户说"多路流用不了"，大概率指这个。
+### 9.2 前端多路流管理 UI —— ✅ 已解决（v2.1）
+- 已补：header 新增 `#btnStreamMgr` 入口 → 弹出「频道管理」模态框 `#streamModal`。
+- 功能：列出所有流（含运行状态/当前标记）、一键切换、删除（main 受保护）、新建（ID+名称，前端正则校验）。
+- 相关：`index.html` 新增 modal 结构；`app.js` 新增 `openStreamManager/renderStreamMgr/switchStream/createStreamFromForm/deleteStreamById`；`style.css` 末尾追加 `.modal-*/.stream-*` 样式。
+- 已验证：后端 create/delete/重复/非法ID/main保护 全通过；app.js `node --check` 通过；JS 引用 ID 与 HTML 无缺失。
 
 ### 9.3 前端 JS 交互未实测
 - `public/js/app.js` 是重写的，只做了语法检查 + HTTP 层测试。
 - **未验证**：SSE 实时刷新、拖拽排序 reorder、mini player、页面切换、导入进度提示等浏览器行为。
 - 建议：手动开浏览器点一遍，看 Console 有无报错。
 
-### 9.4 潜在 Bug 点（未确认）
-- `livestream.js` 的 `enforceCacheSizeLimit` 依赖 `streams` Map，若在 `loadStreams` 前被调用可能拿到空集。
-- `scanner.js` 里 `const parsed = meta.sanitizeFileName;` 是**死代码**（无用变量），无害但可清理。
-- `metadata.js` 的 `enrichSong` 每次启动会对缺元数据的歌重新请求网易云，网络慢会拖启动。
-- 多路流同时播放不同歌时，FFmpeg 预生成队列（并发默认 3）可能跟不上，需观察。
-- `app.js` 里 `esc()` 用了 `String.fromCharCode(38)` 拼接，是**为了绕过工具层的 XML 实体转义**，不要"优化"回字面量 `&`，否则写文件时会被工具吃掉。
+### 9.4 潜在 Bug 点 —— ✅ 已处理（v2.1）
+- ~~`enforceCacheSizeLimit` 依赖 streams Map~~ → 保护集为空时最坏误删缓存，无害；保留。
+- ~~`scanner.js` 里 `const parsed = meta.sanitizeFileName;` 死代码~~ → **已删**。
+- `metadata.js enrichSong` 启动时重匹配慢歌 → 保留（可接受）。
+- 多路流并发预生成排队 → 观察中。
+- `app.js` 的 `esc()` 用 `String.fromCharCode(38)` 绕过工具层转义，**勿优化**。
+
+### 9.4b v2.1 死代码清理 + Bug 修复（本轮）
+- **删死代码**：`media.setCacheCallbacks`（含 `onCacheReady/onCacheError`，无调用方）、`auth.getPassword/isGenerated`、`store.setStreamEnabled/purgeExpiredSessions`、`metadata` 无用的 `sanitizeFileName` 导入导出、`scanner` 死变量 `parsed`。全部 `node --check` 通过。
+- **修 Bug**：删歌时内存 Map（`cacheStatus/retryCount/segmentsCache/inFlight`）残留 → 新增 `live.forgetSong(file)`，删除路由两处改用它，避免同名文件重导读到脏状态。
+- **修 Bug**：`server.js` 移除非法 CORS 头（`Allow-Origin:*` + `Allow-Credentials:true` 浏览器会拒；本地同源应用无需 CORS）。
+- **测试**：45 项全绿（api 16 / e2e 17 / write 5 / 真实 ogg 导入 7）。

+
+> 站在真实使用者角度梳理，按"体验影响"排序。均**未实施**，需老板定优先级。
+
+### 高价值（体验硬伤）
+1. **缺"电台收听页"** —— 现在 `liveLink` 只打开裸 `.m3u8`，浏览器无法直接播放。应在站内加一个 HLS.js 播放页（选频道→收听直播），否则"电台"没法在浏览器里直接听。
+2. **面板无"正在播放"实时卡片** —— 打开面板不知道电台此刻放到哪首。SSE 已推 `now-playing`/`song-finished`，前端只 `loadPlaylist()`，应加一个醒目的 now-playing 展示（封面+歌名+进度）。
+
+### 中价值
+3. **设置页无 UI** —— `/api/system/settings`、`/api/system/config` 已就绪，前端没有对应界面。
+4. **导入上传无进度百分比** —— 现只有"上传中..."文字，fetch 不支持上传进度，需换 XHR + `upload.onprogress`。
+5. **缓存生成无进度** —— 导入后只能看到"生成中/已缓存"两态，无进度条。
+6. **搜索无分页/加载更多** —— `searchNetEase` 固定 limit 20。
+
+### 低价值 / 打磨
+7. **mini player 无音量控制**；8. 无播放历史/最热排序（`heat` 字段已有）；9. 单弱密码 `test123`（正式化要固定强密码，见 §12）；10. 网易云无版权只给文字提示，可做得更友好。
+
+### 已知需实测（无法自动化）
+- 浏览器端：SSE 实时刷新、拖拽 reorder、mini player、上传进度、页面切换动画、频道管理模态框交互。
+
+
+---
+
+## 14. v2.2 前端增强（已完成）
+
+本轮在 v2.1 基础上补齐了用户视角的 4 个高/中价值缺口：
+
+### 14.1 站内 HLS 收听页（`#pageLive`，默认首页）
+- 新增底部导航「收听」tab（5→6 个），作为默认 landing 页。
+- 引入本地化 `public/vendor/hls.min.js`（hls.js 1.5.17，414KB，全本地化无 CDN）。
+- `app.js`：`startLive/stopLive/toggleLive/loadLiveCover`，用 HLS.js 挂载到全局 `#musicPlayer`。
+- 修复了「点 liveLink 打开裸 m3u8 无法播放」的根本问题——现在浏览器内可直接收听。
+- 卡片展示：封面（取当前播放曲目封面）+ 频道名 + 当前曲目 + 播放按钮 + 状态。
+
+### 14.2 面板「正在播放」实时化
+- 发现并修复：后端**从不发 `now-playing` 事件**，前端那个 `es.addEventListener("now-playing")` 是**死监听**，已删。
+- 真正信号是 `playlist-update` / `song-finished`；新增 `refreshLive()`（300ms 节流）接到这两个事件 + 轮询。
+
+### 14.3 设置页（`#pageSettings`）
+- 缓存管理：已用/上限 + 进度条（绿/黄/红三档）+ 一键清理。
+- 运行配置：HTTP 端口/切片时长/窗口/缓存上限/FFmpeg 并发（`/api/system/config`）。
+- 运行日志：tail 行数可选（50/100/200/500），暗色终端风格（`/api/system/logs`）。
+
+### 14.4 上传进度百分比
+- `fetch` 不支持上传进度，新增 `uploadWithProgress()`（XHR + `upload.onprogress`）替换导入逻辑。
+- 上传时实时显示「上传中... N%」。
+
+### 14.5 验证
+- 回归：api 16/16、e2e 17/17。
+- 新增功能校验：12/12（页面元素 + 3 个接口）。
+- HLS 流实测：`/hls/main/index.m3u8` 15 段滑动窗口，切片可达。
+
+### 14.6 待老板浏览器实测
+- 收听页点播放是否出声、切频道是否正确切流。
+- 设置页日志滚动、缓存条颜色。
+- 上传大文件进度条。
+
+
+---
+
+## 15. v2.2.1 资源排序（已完成）
+
+- 资源页头部新增排序下拉 `#resourceSort`：**加入时间 ↓↑ / 热度 ↓↑ / 名称 ↑↓** 共 6 种。
+- 后端 `/api/resources` 补 `createdAt` 字段（取 `songs.created_at`）——之前没返回，时间排序会失效。
+- 前端 `sortResources()` 本地排序；名称用 `localeCompare(..., "zh", {numeric:true})` 支持中文与数字。
+- 与搜索框组合：排序改数据顺序，搜索只是隐藏不匹配项，二者不冲突。
+- 测试脚本改为**动态基线**（不再硬编码 5 项），新增歌曲不会误报。回归 38/38 全绿。
+
+
+---
+
+## 16. v2.3 UI 去 AI 味重构（已完成 2026-09-24）
+
+> 原「MIUIX 风格重构」任务。老板改方向：**不找 MIUIX**（那是 Compose 的），改用 GitHub `ibelick/ui-skills`（Web 版设计工程 skill）的规则手工重构。
+
+### 16.1 采用的 skill
+- **`C:\Users\xiao\.claude\skills\ui-skills`**（clone 自 github.com/ibelick/ui-skills，9046★）。
+- 关键规则（`skills/baseline-ui/SKILL.md`）：**禁渐变**、禁紫/多彩渐变、禁 glow 当主视觉、单视图单强调色、交互反馈 ≤200ms、入场 ease-out、只动 transform/opacity。
+- 我们的项目是原生 HTML/CSS/JS（非 Tailwind/React），只取其**原则**，类名约束不适用。
+
+### 16.2 改动清单
+1. **频道管理+切换合并为单一入口**：
+   - 删除 header 的 `<select id="streamSelect">` 下拉 + 原「频道管理」按钮，合并为单一按钮 `#btnStreamMgr.channel-btn`（图标+当前频道名 `#currentChannelName`），点击打开原有 `#streamModal`（内含切换/删除/新建）。
+   - `app.js`：`loadStreams()` 不再填 select，改写 `#currentChannelName` 文本；删除 select 的 change 监听；`switchStream()` 补 `if (livePlaying) stopLive()`。
+   - `style.css`：`.stream-select` 样式 → `.channel-btn`。
+2. **去 AI 味（清全部渐变/glow）**：
+   - `page-bg` 径向光晕 → 纯色 `var(--bg)`；`.bg-shapes` 紫色 `#8b5cf6` → `var(--accent)`。
+   - `.about-hero` 渐变 → `var(--accent-light)`；`.mp-progress` 渐变 → 半透明纯色。
+   - `.live-cover-ph` / `.live-play-btn` / `.live-progress-fill` 橙红渐变 `#ff5f6d→#ffc371` → `var(--accent)`；play-btn glow 阴影 → `var(--shadow-sm)`；live-badge glow → 中性。
+   - `.cache-bar-fill` 三档渐变 → `var(--success/--warning/--danger)`。
+   - live 区、modal 区硬编码色（#222/#999/#333/#888/#fff/rgba）统一改为 token。
+   - 保留：login.html 暗色径向（独立深色主题，非 AI 味）。
+3. **测试更新**：`test_e2e.py` 断言 `id="streamSelect"` → `id="btnStreamMgr" and id="currentChannelName"`。
+
+### 16.3 验证
+- `node --check public/js/app.js` 通过。
+- 回归：api 16/16、e2e 17/17、write 5/5（需先 ffmpeg 生成 `tmp/test_import.mp3` 素材）。
+- 全局扫描：public/ 下渐变计数 = 0（除 login.html 暗色径向）。
+
+### 16.4 备份
+- `F:\music_online\demo_backup_20260924_2129`（本次改动前的备份，仍有效）。
+
+### 16.5 待老板浏览器实测（无法自动化）
+- 频道按钮点开弹窗、切频道是否正确换流。
+- 收听页配色是否满意（现为单 accent 蓝，无渐变）。
+- 各项 hover/动效观感。
+
+### 16.6 未做 / 可选后续
+- 是否 `git commit`（工作区改动含本次 + 上轮 v2.2，均未提交）。
+- 深色模式、缓存条颜色再打磨、其余「AI 味」细节。
