用户报告：「一断网就退出到扫码登录界面，不会保持账号态切离线，缓存列表形同虚设」。 上一条已把失败分成 NETWORK/AUTH；本条把结论落到 App 状态与 UI。 - 会话状态机（appstate.c）：只有 NCM_ERR_AUTH（401/403/301/302）清 cookie；网络类失败 （不可达/超时/TLS/5xx/-460）只置 g_st.offline，账号态与 session.enc 一律保留； appstate_ensure_uid 同语义（原先任何 AUTH 都清 cookie，网络故障不得进入该分支）。 - 启动（app.c）：根页改由 ncm_session_boot_decide 决定——有本地会话就进 home（无网也是）， 只有无本地会话才进扫码；打印 boot 决策日志。 - 离线 UX：首页个人卡「离线模式」红标 + 页脚提示 + 空态「离线模式/可播放已缓存」； 歌单页/搜索页/播放页/缓存页分别给出离线文案（缓存页点播照旧走 NCM_QUEUE_CACHE，本地可播）。 - 恢复：home 可见时每 30s 静默重试一次（强制绕过接口缓存，成功即回在线并重绘）； 任何真实网络成功（home/playlist worker）也会清离线态。 - 防误判：接口缓存命中（120s 旧响应）不算「回在线」——home_worker 用 ncm_apicache_hits() 差分识别，避免离线提示被缓存命中闪掉。

/* ui/cache.c — 已缓存列表页（ACT_CACHE，首页顶栏「已缓存」钮进入）。
|
||
*
|
||
* 数据源：songs/ 音频池（键=歌曲ID+请求档位，NCM_CACHE_DESIGN §2.5）。扫描在 worker：
|
||
* ncm_cache_scan（读目录 + 文件头 tag + 音频参数探测）→ appstate 快照；
|
||
* UI 线程只读快照（零磁盘 IO），列表由 meow_listview 虚拟化。
|
||
* 行：歌名 / 歌手 · **实际档位** · 大小。**档位显示实际档而非请求档**：缓存名里的档位段只是
|
||
* 请求档（真机存在 song_<id>_hires.mp3 = 无损请求被降级链落到 exhigh mp3），实际档由
|
||
* 文件头（FLAC bps/采样率、MP3 首帧码率）推断。
|
||
* 交互：点行=点播（NCM_QUEUE_CACHE，上/下一首在缓存列表内循环）；行右「删除」=单曲删除；
|
||
* 顶栏「清空」=清空缓存池（确认框，与设置页「清理缓存」同语义）。
|
||
* 主题/控件惯例同 queue.c：圆角卡 + 红 mini-vinyl + 按压红条 + 当前播放行高亮。
|
||
* 左缘返回=弹回首页（app.c）。
