+# PKG-MULTI-SUB-03 模块边界与资源修复
+
+本次修改生产源码，保持工厂名称/必需参数、async 注册结果、name/tracks/reset、同步 void
+选择方法和原分发入口。自有 JS 先按职责拆清，严格 TS 与公开声明仍由 04 完成。
+原始 parser、许可和公开类型未改，没有新增依赖或改变包版本。
+
+## 结构变化
+
+| 文件 | 实际职责 |
+| --- | --- |
+| index.js | 注册编排、名称选择、活跃状态检查和公开返回对象 |
+| request.js | 每轨请求、原生状态检查、字节解码与既有核心格式转换 |
+| merge.js | 解析元数据和按选择顺序序列化；通过复制 cue 包装文本，原树不变 |
+| lifetime.js | 本次注册的 destroy 监听、请求取消、Promise 提前结束与清理登记 |
+| render.js | Blob 所有权、新旧 URL 替换、重入保护及宿主 init 失败处理 |
+| parser.js | 保持原始 vendor 边界，不因本次拆分改写算法 |
+
+模块依赖由入口向请求/纯解析/安装流动；仅入口和宿主安装/生命周期需要 art，纯 merge
+不依赖 DOM、fetch 或播放器。没有引入要求用户升级核心的共享运行时依赖。
+
+## 独立缺陷修正
+
+- 销毁中 fetch/body 通过取消信号和关闭 Promise 结束；无 AbortController 的旧环境仍
+  能及时结束注册并忽略迟到结果。返回相同形状的失活结果，不新增 destroy 拒绝。
+- 单轨失败保留原传输/解码异常身份，关闭整个注册并取消兄弟请求；HTTP ok=false 明确
+  拒绝且取消未消费的响应，不再把错误页面当作有效字幕。
+- 最后 Blob URL 在 destroy 时释放。保留的 tracks/reset 此后返回 undefined，不再
+  读取名称、分配 URL 或触发宿主。重复 destroy 不重复释放。
+- 分配新 URL 成功后才尝试替换；分配失败保留旧 URL。同步 init 失败释放新 URL，
+  保留先前资源并回滚该次 escape 写入；首次注册失败同时移除监听。
+- 观察宿主真实 Promise 的 rejection，释放失败安装对应的 URL，并在活跃时以 console.warn
+  保留诊断。正常注册仍不等待宿主加载；tracks/reset 仍为 void。宿主核心可能自行显示
+  notice，这里不引入新公开事件，也不假装异步错误会从旧 void 方法同步抛出。
+- 老 init 的迟到错误不释放后来成功替换的资源；同步重入选择、配置读取失败，以及
+  用户 getter/init 中触发 destroy 都有明确归属检查。
+
+异步 init 失败发生时，宿主可能已经更新自身状态；插件不能通用回滚第三方宿主的副作用。
+此时释放失败资源，保留旧异步接口时序并记录错误；调用方可在仍活跃时重新 reset。
+正常 destroy 不恢复共享 subtitle.escape，避免覆盖后续插件/用户的配置。
+
+## 保留的兼容边界
+
+1. 采用已发布 1.2.0 的逐轨连接语义；没有恢复 1.0.0 按下标丢 cue 的缺陷。
+2. 轨内 parser 排序、轨间选择顺序、同名取第一个、重复选择、未知名 TypeError、空轨、
+   onParser 未执行，以及坏 header 仍可保留可用 cue 的容错均保留。
+3. option.type 优先、当前核心 SRT/ASS 转换、encoding 默认与原生解码行为保持。
+   轨元数据在下载结束后读取；restart 不重新下载字幕，配置在每次安装时读取。
+4. 不再调用无实际资源的 revokeObjectURL('')。历史测试仍断言旧调用记录，候选正常
+   测试仅对这一项无资源清理差异作明确区分，不放宽真实 URL 的释放断言。
+5. 合并不再原地标记 updated/改 cue；冻结树重复序列化测试和九种真实旧产物逐字对照
+   证明输出保持，另对实际核心转换和 Windows-1252/UTF-16LE 字节逐字比较。
+
+## 验证与限制
+
+命令及准确运行结果、输入指纹、原生浏览器观察见
+[验证记录](../baselines/multiple-subtitles-resources.json)。新生命周期/merge 文件接入
+test:unit 与 test:multiple-subtitles，生产三入口由正常 yarn build 生成。
+浏览器矩阵使用发布/候选核心、Chromium/Firefox/Windows WebKit 和源码/现代/legacy
+插件，覆盖 SRT 显示/选择、挂起请求销毁、原生 Blob 不可访问、HTTP 失败及真实视频切源。
+其中资源/错误场景直接执行公开注册函数，显示与切源场景使用真实 plugins.add。
+
+最终本包 241 项通过；源码/main/legacy 各 31 项通过（其中冻结树纯函数用例固定读取源码，
+其余正常/生命周期/转换对照通过选定入口）。三入口原生浏览器各 30 项，共 90 项通过。
+完整 CI 2311 项通过：1963 单元、14 工程、334 基线；严格生产 TS 仍 346 文件。
+状态更新后 9 项风险/契约元数据测试通过。显式 lint 无错误或警告；全量 lint 仍有既有
+生成声明 unused-disable 警告。实际 ESM 只验证导出形状和工厂，不冒充完整安装消费者。
+
+这不是全部历史核心、实体 Safari/移动设备、ASS 原生显示、样式/编辑器或 npm 发布准入。
+HOST/HTTP 在本次边界回归后关闭；LIFE/MERGE 的完整支持范围组合仍由 05 补齐。
+每项状态以 tasks/risks 与验证记录为准；后续 04 迁移 TS 时重跑相同生产入口用例。
+
+独立本地任务提交，不推送、不发布。回退本提交恢复旧单文件和生成产物，同时重新引入
+02 已复现的泄漏/失败行为；02 历史基线及浏览器证据保留。
