v4.2.1

ColorOS Live Lyrics Bridge v4.2.1

Readify TTS Provider / Readify TTS Provider

4.2.1 将 io.github.andrealtb.coloroslyrics.provider.readify 纳入正式 Provider
矩阵。它面向 Readify AI 3.1.0 的 com.readin.app，通过宿主已有 MediaSession
发布事件驱动的句子窗口；Bridge 保持只运行于 system 和
com.android.systemui。

All 14 Provider modules use libxposed API 102 with static scope and protective exception handling.

• sentence-window-v1 使用当前句索引保持高亮，避免 TTS 在未知时长时提前滚动。
• 最多五句的窗口可完整展示长文本，未伪造音频时间轴、播放状态或额外 MediaSession。
• Provider 仅读取宿主已预取的 Chunk AI/Readium 缓存，不推进朗读器或发起额外合成请求。
• Readify 继续严格锁定宿主 3.1.0；未知版本不发布歌词。正式 APK 的最终真机安装验证仍待补充。

发布与升级

1. 安装同一 v4.2.1 Release 中的 Bridge 与所需 Provider APK。
2. Readify Provider 仅在 LSPosed 中勾选 com.readin.app；Bridge scope 只保留 system
   与 com.android.systemui。
3. 不要同时启用历史测试包 de.sqlsec.readifylyrics 与正式 Readify Provider。
4. 更新后重启 Readify、SystemUI；首次安装或 scope 变更后按设备需要重启。

Release validation

• Provider matrix now contains 14 API 102 modules: 12 dedicated providers, Universal Player, and Readify.
• The tag workflow validates 14 Provider APKs, 15 APKs total, and 18 release assets, including
  package/version metadata, certificate, zipalign, DEX guards, Provider ZIP, manifest, and SHA256SUMS.
• The workflow resolves Providers main to a full commit SHA before build; the release manifest
  records that SHA and later stages use only the frozen commit.
