- 新录像写成格式 2：未压缩文件头 + 按块 zlib 压缩，块头记录时间范围、记录数、 长度和 CRC；flush 即封块，崩溃只丢最后一次 flush 之后的内容，损坏块读作结尾 - 旧格式 1（整文件 gzip）照常读取，按文件头魔数自动识别，不转换、不改原文件 - NovaReplayFile.scanIndex：格式 2 只读块头跳过正文，格式 1 后台整段扫描； 回放打开后在后台线程建索引得到时长 - ReplayStream：独立线程预读，内存只保留播放头前方有界窗口（堆的 1/32，8–64MB）， 录像多长都一样 - ReplayCursor：跳转只改目标，每 tick 按墙钟 60% 的预算分片应用记录；往回跳仍需 从 0 重建世界（包流无法倒放），但改为分片进行；时钟在追赶期间暂停 - ReplayPlayback：打开只读文件头；重建期间原版载入界面结束后恢复先前界面； 覆盖层和回放界面显示"加载中 N%"；去掉"录像过大只载入前 N 分钟"的截断 - 导演工作台：追赶期间不推进输出时钟，导出等世界追上后再截帧；索引到达后 自动补全工程时长 - 单测：读写往返、损坏块、索引、旧格式读取与跳转、正反向跳转定位、 零预算逐条推进、190MB 合成录像下预读峰值不超过窗口
- 依赖与 bundledRuntime 改为 1.0.2；vendor/maven 换成本地构建的 1.0.2 （mcef-nova release/1.0.2 @ f0c9055），移除 1.0.1 副本 - GitHub Packages 上目前只有 1.0.2-SNAPSHOT，CI 注释里留 TODO，待正式发布后 填 tag 并替换 vendor 副本
- BrowserOwnedTexture（26.2）：每帧上传前 dst.clear()。上一帧把 limit 缩到当帧 大小，窗口先缩后放时绝对 put 越界，网页永久黑屏 - AcceleratedBrowserTexture（1.21.5–1.21.11）：GlTexture 反射构造参数顺序改为 usage 在第 1 位、glId 在第 8 位（已用 1.21.8/1.21.11 字节码核对：参数 1 写入 GpuTexture.usage，参数 8 写入 GlTexture.id） - AcceleratedBrowserTexture（26.2）：从桩实现换成零拷贝实现，把 mcef 导入的纹理 用 glCopyImageSubData 拷进设备纹理并以 GL swizzle 处理 BGRA；ClientBrowser 26.2 分支在加速时绘制它，失败回落 CPU 路径（已核对 26.2 GlTexture/GpuDevice 布局） - Client.configureHost：开启硬件加速且平台支持时设置 mcef.pumpOnRenderThread， mcef 1.0.2 只在渲染线程泵模式下启用共享纹理
