+Cleanup records whether an exception occurred separately from its value. It attempts
+all remaining cleanup callbacks and then rethrows the first value unchanged, including
+undefined, null, false, zero, an empty string or NaN. In particular, a destroy listener

+# PKG-TOOL-THUMB-07 保留清理中的原始异常值
+
+来源 HEAD：`2a380679117b02499ff3a131cb449e1eda007cb2`。
+本任务修复迁移中的兼容回归，不改变待批准的 Thumbnail 默认行为方案。
+对应 API-04 事件异常传播和 API-05 销毁/资源清理。
+
+## 缺陷与修复
+
+恢复的3.5.31 CDN文件及冻结工作区 main/legacy 在 destroy 监听器抛出 undefined、
+null、false、0、-0、空字符串或NaN时，均同步向调用方传播原值。迁移后的
+cleanupAll 使用异常值的 truthiness 判断是否失败，导致这些异常被吞掉；如果
+后续清理再抛出 Error，后一个异常还会覆盖第一个值。
+
+新增回归在未修复候选上1通过、2失败：历史契约通过，候选在首个undefined的
+传播及后续异常覆盖检查失败。修复后的全部七种值都被实际检查，使用独立的
+threw 标记和 Object.is，避免“没有抛出”和“抛出undefined”混淆，也区分-0与0。
+
+实现仅调整 src/lifecycle.ts 的 cleanupAll：使用单独 failed 布尔值记录异常发生，
+保存第一个原始值；继续执行所有后续资源清理，然后按原值抛出。没有改变正常
+返回路径、清理顺序、事件名称、默认参数、同步/异步形状或类型声明。
+
+销毁先将实例关闭，失败后再次 destroy 仍不重复执行。cleanupAll 的继续清理
+不代表 emitter 改为继续派发：destroy 的一个监听器抛出后，当前派发中其余
+监听器仍不执行。测试同时检查这两层边界。
+
+## 验证
+
+| 验证 | 结果与范围 |
+| --- | --- |
+| 新回归旧红/新绿 | 未修复1通过2失败；修复后3通过，包含七种 falsy 值、原始异常身份、继续清理和重复销毁 |
+| 源码专项 | yarn test:thumbnail：123通过 |
+| 正式 main/legacy | 各49项输入、抽帧、清理和 emitter 单测通过 |
+| 源码真实浏览器 | 15通过：3份历史实现及候选的原始异常、真实DOM清理，以及现有事件注册回归 |
+| 已安装 main/legacy 浏览器 | 各21报告通过；每轮5项Windows WebKit为Blob能力受限对照，不计抽帧成功 |
+| 其余检查 | 严格包类型、定向lint、正常三格式构建、严格工具链通过 |
+
+浏览器共57报告通过，其中47项实际执行对应正常场景，10项是明确标注的
+WebKit能力对照；没有失败或重试，也没有把受限对照记作成功抽帧。main/legacy
+还覆盖正常PNG像素/重复生成、拖放、损坏媒体后切源、迟到编码与销毁/替换取消。
+
+Node24.21.0、YarnClassic1.22.22；隔离包由
+`yarn test:thumbnail-types-package` 实际打包、在仓库外安装、冻结离线重装并核对
+每个文件。安装后的7项候选正例通过、52项预期负例诊断成立；5项历史工作区
+缺入口/声明的预期失败保持原样。编译器为TS5.9.3及4.3.5，不能称为12项旧声明
+全部编译通过。历史工作区夹具也不是已找回完整npm3.5.31归档。
+
+包内 ARCHITECTURE 已在打包前更新。三份dist、docs/compiled副本和已安装副本
+字节一致；公共types未变。源浏览器检查后仅规范了等价的window全局访问及格式，
+最终测试文件已用于main/legacy运行。root test:thumbnail 与 test:unit 均新增此
+回归，无新增依赖、版本变更或锁文件修改。
+
+机器证据：[thumbnail-cleanup-errors-validation.json](../baselines/thumbnail-cleanup-errors-validation.json)。
+命令入口和职责随包内文档一起维护。此任务不关闭04的默认值冲突，也不代替
+05/06的最终组合、设备或完整分发验收；本轮未推送、部署或发布。
+
+## 回退与交付
+
+回退本独立提交会恢复有缺陷的 truthiness 判断，撤销对应测试、文档和本轮
+构建产物；不撤销此前的TS迁移、输入/抽帧资源归属和emitter修复。
+本任务以PKG-TOOL-THUMB-07单独完成并提交，04继续doing。

 # 进度与证据
 
+## PKG-TOOL-THUMB-07 清理异常传播修复
+
+修复cleanupAll吞掉destroy监听器抛出的falsy值、或被后续异常覆盖的兼容回归。
+历史3.5.31/工作区保留原值，未修复候选1通过2失败；修复后继续释放资源，保留
+第一个原始异常，重复销毁仍不执行，普通事件派发遇错仍停止。
+
+123源码专项、main/legacy各49专项通过；源码及实际安装产物共57浏览器报告
+通过，其中10项是明确的Windows WebKit Blob能力对照，不计抽帧成功。7项安装
+类型正例、52预期负例诊断、5历史缺入口/声明对照成立；三格式/文档副本字节
+一致。详见[记录](changes/2026-09-15-PKG-TOOL-THUMB-07-cleanup-errors.md)和
+[证据](baselines/thumbnail-cleanup-errors-validation.json)。
+新增独立任务07完成，04的默认兼容决策保持待处理；204 done、21 doing、43 todo，
+共268项。无新依赖、版本变更或发布操作。
+
 ## PKG-HLS-SDK-01 SDK顺序与销毁前崩溃
 
 新增固定SDK序列诊断入口，逐页核验版本并保存实际顺序。在同一个Firefox实例
