+# PKG-MASK-02 历史错误与生命周期观察
+
+本任务新增历史测试、专属 helper 和证据，并接入根测试脚本；未修改生产或生成产物，未执行模型，
+没有浏览器服务器、推送或发布。PKG-MASK-03 仍依赖 PKG-DANMUKU-07；该依赖尚未
+满足，生产重构按任务依赖继续推进。本任务不代表 SDK-08 完成。
+
+## 输入和可重放接缝
+
+源码来自 `b0cfbfe3a09a84a295a257e45e4577847588d1cb`；真实 npm 1.0.0/1.1.0
+tarball 来自 MASK-01 的 SHA512/SHA256 冻结。源文件与六个 main/legacy/module
+成员共七个输入，标识见 [机器报告](../baselines/danmuku-mask-failures-validation.json)。
+
+两种探针必须区分：
+
+- MASK-01 已用**未改写的归档字节**验证 CommonJS/script 导出、注册和 stop，未启动模型。
+- MASK-02 的历史生命周期探针对归档导出工厂内部 **五个 SDK 调用表达式的 callee**
+  做受控替换：setBackend(webgl/cpu) 两处、createSegmenter/toBinaryMask/drawMask
+  各一处。inline SDK 函数表达式作为整体替换，原插件异步流程、生命周期、错误处理、
+  canvas 操作与旧版 async helper 保留。module 先以 esbuild 转为 CJS，因此不算
+  原生 ESM 验收。冻结源码仅转换模块形式，通过 require seam 注入 SDK 替身。
+
+helper 首先校验真实归档，再从实际导出函数定位唯一原文字段，用 TypeScript AST
+寻找接缝。固定替换数量不是模糊匹配后继续运行：任何数量不符直接失败。报告保存
+原成员哈希、转 CJS 后哈希、探针哈希、每个 callee 的范围/旧表达式哈希。首项测试
+逐项比较报告，变化必须显式审查。实际 SDK 顶层注册可执行，但没有模型初始化、
+模型网络、GPU 或媒体推理。探针 fetch 被拒绝；错误探针不得以网络错误替代目标错误。
+
+## 实际观察
+
+七个输入都复现以下三个历史缺陷，共 21 项：
+
+| 触发 | 历史结果 |
+| --- | --- |
+| 初始化 pending → stop → 完成初始化 | stop 的 maskImage=none 被后续 mask 写入覆盖，重新安排 RAF |
+| 推理 pending → destroy → 推理完成 | 销毁后仍画 mask/排 RAF；segmenter 未 dispose，ready/destroy listener 留存 |
+| 初始化完成后再次 start → stop | 两条 RAF 链，stop 只取消最后记录的一条；剩余链下一轮重新写 mask |
+
+详细错误矩阵集中在冻结源码与 npm 1.1.0 main，各 16 项，避免为所有格式机械重复：
+
+| 触发 | 历史结果 / 关联风险 |
+| --- | --- |
+| 初始化 pending 时 stop 或 destroy | 后续模型仍存活，不 dispose；MASK-LIFETIME-01 |
+| 推理 pending 时 stop | 晚到结果覆盖 none 并排新 RAF；MASK-LIFETIME-01 |
+| 同时两次 start | 创建两个模型、两条 RAF，destroy 后仍剩一条，两个模型均未 dispose；MASK-START-01 |
+| segmentPeople rejection | 每帧记一次错误并重试；改为成功后能再画 mask；MASK-BACKEND-01 |
+| setBackend(webgl) fulfilled false | 不尝试 CPU，继续初始化；MASK-BACKEND-01 |
+| WebGL rejection、CPU fulfilled true/false | 均尝试 CPU、记录一次 warning、继续初始化，忽略返回 boolean；不是 MediaPipe CPU 推理证据 |
+| CPU rejection，经显式 start 调用 | Promise 以同一错误拒绝，尚未创建模型或排 RAF |
+| createSegmenter rejection | 记录错误，但 start resolve；以后 RAF 只轮询，既不推理也不自动重新初始化 |
+| 缺少 $danmuku | start 在模型创建后以 TypeError 拒绝；stop 也抛错，模型未 dispose；MASK-DOM-01 |
+| getContext 返回 null | start resolve；读图像时报 TypeError 并排下一帧，旧 mask 不被清除 |
+| createElement(canvas) 抛错 | start 以同一错误拒绝；已初始化模型在 destroy 后仍未 dispose |
+| getImageData 抛受控 SecurityError | 错误被记录并重试，既有 mask 留存；这不是原生 CORS 复现 |
+| RAF 返回 0；destroy 后再次 ready | truthiness 判断漏取消 0，保留 ready listener 可再启动一条链 |
+| ready 内 CPU rejection | 被事件调度丢弃的 start Promise 产生未处理拒绝 |
+| 缺少 $video | segmentBody 在 try 之外读 paused，产生未处理拒绝 |
+
+加上接缝身份验证，共 **54 项历史测试**。未处理拒绝的四项各启独立 Node 子进程，
+使用 `--unhandled-rejections=strict`，验证子进程 exit=1 和指定错误；父进程没有安装
+unhandledRejection handler，子进程也没有吞错 handler。子进程只能以指定错误失败，
+AssertionError 或禁止网络错误均不作为通过。测试进程本身没有实际 RAF 定时器；
+故意留存的历史帧只在该测试的 Map 内，不会泄漏到真实 UI。
+
+## 验证及后续约束
+
+固定 Node 24.21.0：
+
+```sh
+node --test test/danmuku-mask-failures.test.js
+node node_modules/eslint/bin/eslint.js test/helpers/danmuku-mask.js test/danmuku-mask-failures.test.js
+yarn test:danmuku-mask
+```
+
+54 项通过、0 fail、0 skip；专属 lint 通过。日志
+`refactor/.cache/danmuku-mask-failures-final.log`，机器报告记录其哈希和输入身份。
+这里只证明旧缺陷可重跑，**这些结果不能变成候选验收期望**。后续候选测试应独立
+验证异步失效、模型单一归属、RAF 单链、适当错误传播/事件处理和销毁清理；不要靠
+将本套测试切换到候选 source 来保留已知问题。SDK-08、真实模型/设备/视频/浏览器
+与新旧核心组合仍由 05 验收，通知/资源最终分发由 06 核实。
+
+父代理独立复跑54项通过，加入现有test:unit使CI自动执行；专属
+test:danmuku-mask同时覆盖01的六项契约。未安装依赖或更改Yarn锁文件。
