bilibili、netease、youtube：各平台的请求、账号、缓存和播放来源 / platform requests, accounts, caches, and playback sourceslyrics、search：歌词检索、匹配与元数据搜索 / lyric lookup, matching, and metadata searchcomments：评论分页、映射与缓存 / comment pagination, mapping, and cachingnetease/encyclopedia：歌曲百科请求、解析与内存缓存 / song encyclopedia requests, parsing, and memory cache
各平台内部的 api 负责请求协议，通过注入接口获取凭据；账号和缓存由仓库管理。Room 实体与 DAO 在 :database，跨平台本地歌单在 :local。本库还依赖 :model、:lyrics、:common 和 :network。
Each platform's api package handles protocols with injected credentials; repositories manage accounts and caches. Room entities and DAOs live in :database, and cross-platform local playlists in :local. Other dependencies are :model, :lyrics, :common, and :network.
歌曲百科通过 SongEncyclopediaRepository 返回成功、不支持、无资料和可重试失败四种结果；当前实现仅查询具有网易云来源身份的歌曲，不将缺失资料当作网络错误，也不为其它来源推测百科内容。
SongEncyclopediaRepository distinguishes success, unsupported sources, unavailable data, and retryable failures. The current implementation queries songs with a NetEase source identity, keeps missing data separate from network errors, and does not infer encyclopedia content for other sources.
YouTube 脚本在 src/main/assets/youtube；youtube/api/challenge 管理 EJS 挑战、播放器脚本缓存、共享 JavaScriptSandbox 与本地 WebView 回退。NewPipe 所需的 Rhino 反射入口由 consumer-rules.pro 保留。凭据文件、键名和序列化名称需兼容已安装版本。
YouTube scripts are in src/main/assets/youtube. youtube/api/challenge owns EJS challenges, player script caching, the shared JavaScriptSandbox, and the local WebView fallback. consumer-rules.pro preserves Rhino reflection entry points needed by NewPipe. Credential files, keys, and serialized names must remain compatible with installed versions.
