+# ENG-04:类型检查基础落地
+
+日期 2026-09-10;起点 09902b8b;分支 codex/compatible-modernization。
+
+新增根/核心/chapter tsconfig、浏览器资源声明、yarn typecheck 与 CI 接入。脚本自动发现分包配置,禁止严格检查退化为跳过声明或生成产物,并拒绝新 TS 包缺少配置。实现检查和消费者解析模式分开,当前核心/chapter 的生产 TS 文件数诚实输出为零;本任务没有改写生产源码或公开声明。
+
+固定 TypeScript 5.9.3;新增根开发 alias typescript-compat=typescript 4.3.5,支持精确 alias 的 Yarn 工具检查与拒绝浮动 alias 的回归。4.1.6 试探无法解析现有类型内 getter,最终依赖已移除;4.3.5 是当前已测旧版本点,不是对全部历史消费者下限的新声明。
+
+3 个严格配置通过;现代 TS 的 Node10+CJS、NodeNext+CJS、Bundler+ESM,以及 4.3.5 Node10+CJS 消费通过。NodeNext ESM 的 7 个既有诊断逐条保存并关联 BASE-TYPE-01,不当作候选通过。原发布包四模式/16 场景仍由基线测试执行;新增实际错误 URL、无效错误断言和源码类型错误的回归,不用跳过/any 消除历史差异。
+
+验证:完整 ci:check 通过工具链、计划、只读 lint、类型入口、21 项 Node 和 19 项基线测试,共 40 项;特定类型文件 lint 通过。冻结安装核对新依赖;原 1335 个 lock selector 的版本/integrity 全同,只增加一个 alias。Yarn 合并了 esbuild/p-map 同版本 selector;esbuild 的已存在 selector resolved 合并到相同内容的 Yarn registry 地址,未升级生产依赖。
+
+实际文件职责、运行命令、JS/TS 边界、旧编译器范围与后续工作见 [维护说明](../typechecking.md)。独立提交 ENG-04,撤销本提交可恢复原检查和依赖,不影响生产产物。下一项 ENG-06 让正常构建支持 TS 和非交互选包,随后接续单元/浏览器测试服务与 chapter 试点。

+# 已实现的类型检查与迁移入口
+
+ENG-04 使用开发编译器 TypeScript 5.9.3,并将 TypeScript 4.3.5 作为 npm alias typescript-compat 固定在根开发依赖。后者仅用于旧编译器消费回归,不进入播放器运行依赖或产物。Yarn 锁文件校验现在接受精确版本的 npm alias,仍拒绝范围和浮动版本。
+
+## 命令及真实覆盖
+
+```sh
+yarn typecheck
+yarn ci:check
+```
+
+typecheck 读取根及已建立配置的分包项目,以编译器 API 执行,不依赖两个 TS 安装可能影响的全局 tsc 命令。当前根配置检查两个消费/浏览器类型文件,核心检查 14 个声明及共享资源声明,chapter 检查自身声明及共享资源声明。配置实际编译经过的生产 TS 文件数另行输出;本任务完成时为零,不能把声明检查说成生产 JS 已严格检查。
+
+自动检查当前工作区的 TS 5.9.3 Node10+CJS、NodeNext+CJS、Bundler+ESM 及 TS 4.3.5 Node10+CJS。正例包括旧配置、ready 回调 this、插件、play 和 update;反例拒绝错误 URL/章节时间。没有 ts-expect-error 生效时编译也须报错,防止 any 或声明放宽使反例失效。
+
+TS 5.9.3 的 NodeNext ESM 当前有 7 个准确诊断,单独保存在 test/types/known-diagnostics.json,并绑定 BASE-TYPE-01。它们来自原有默认导出声明互操作问题;检查输出明确是历史失败,不能作为候选验收通过。修复由 CORE-07、PKG-CHAPTER-04 和 ENG-07 接续,届时移除对应失败记录、增加成功消费断言,不能一键刷新以容忍新回归。
+
+BASE-05 的四模式、16 场景、真实发布 tarball 隔离验证仍由 test:baseline 执行。本入口补上当前工作区的检查,不代替隔离发布消费;ENG-07 接入候选 tarball。BASE-TYPE-02/03/04 的可选参数、legacy 声明与返回值问题继续由原任务负责,没有在本任务偷偷修改生产声明。
+
+## 配置与文件职责
+
+| 文件 | 职责 |
+| --- | --- |
+| 根 tsconfig.base.json | 浏览器实现基线:ES2020+DOM/DOM.Iterable、strict、noUncheckedIndexedAccess、noImplicitOverride、noEmit、skipLibCheck=false、types=[] |
+| 根 tsconfig.json | 当前公共消费与浏览器环境类型用例;不是无条件将全部遗留包标为已检查 |
+| packages/artplayer/tsconfig.json | 核心自有 TS 及现有公开声明的入口 |
+| packages/artplayer-plugin-chapter/tsconfig.json | 试点 TS 及现有公开声明的入口 |
+| types/assets.d.ts | 当前 Less inline 和 SVG 的 string 导入类型;不提供泛化的任意模块声明 |
+| scripts/typecheck.mjs | 固定编译器检查、分包发现、四种现代消费模式、兼容编译器与历史诊断核对 |
+| test/types/ | 真实旧调用、无 Node 全局污染/数组越界反例、明确历史诊断;无运行时副作用,因为只编译不执行 |
+| refactor/scripts/types.test.mjs | 验证非法旧调用、无效错误断言和生产 TS 错误确实被拒绝,检查不生成 JS |
+
+实现由现有 bundler 构建,所以源码配置采用 Bundler 模块解析;发布声明仍须经过独立 Node 模式验证。[TypeScript 模块解析说明](https://www.typescriptlang.org/tsconfig/moduleResolution) 区分了这些模式,[官方编译器选项指南](https://www.typescriptlang.org/docs/handbook/modules/guides/choosing-compiler-options) 也说明 bundler 成功不保证未打包声明能被 Node 消费。
+
+allowJs=true、checkJs=false 允许渐进迁移时引用旧 JS;只将迁移的 TS 和声明纳入配置根文件,旧 JS 不因被引用就变成已迁移。迁移任务须缩小不明确的 JS 边界,vendored 独立列入第三方台账,不能用 ts-nocheck/any 把自有代码隐藏过去。新增生产 TS 的包若没有 tsconfig,入口会拒绝继续。
+
+不默认启用 exactOptionalPropertyTypes 去收紧旧调用允许的显式 undefined;公开类型接受范围变化需要逐项消费者证据。内部数组/索引检查启用 [noUncheckedIndexedAccess](https://www.typescriptlang.org/tsconfig/noUncheckedIndexedAccess.html),防止将不存在的元素当作已存在。浏览器 types=[] 防止依赖树中的 @types/node 自动污染 DOM 代码;worker 和 Node 工具需要自身配置,不把 DOM 与 WebWorker 全局混在一起。
+
+## 编译器版本边界
+
+4.1.6 试探无法解析当前 artplayer.d.ts 的类型内 getter(首个错误在 template.html);已改用实际通过公共消费样例的 4.3.5,并从最终依赖/锁文件移除 4.1.6。4.3.5 是当前核心/chapter 的已测旧编译器点,不是证明所有历史版本都以它为最低,也不是授权抬高用户已有支持窗口。其他包在自身契约任务核对声明语法和实际旧版本消费者;未查明时保持未知。
+
+源码检查用 5.9.3 不要求用户也使用 5.9.3。生成声明时须保留旧编译器能理解的公开语法,并在版本落实和候选 tarball 后重跑。NodeNext/Bundler 的消费模式由当前编译器验证,不传给不具备这些模式的 4.3.5。
+
+## 后续接入
+
+新迁移包复制分包配置并按实际运行环境调整,加入特有正反例;编译器入口自动发现包配置。TS 构建入口与声明生成由 ENG-06/07 和各包迁移处理;不能只增加一个空 config 就宣布包迁移完成。所有生产变更仍按每任务独立提交和包内架构文档规则交付。
