+# Core implementation and migration map
+
+ArtPlayer keeps its existing constructor, player mixins, plugins and DOM/CSS hooks.
+The production entry is still `src/index.js`; this document marks actual migrated
+boundaries rather than describing the entire core as TypeScript.
+
+## Current TypeScript boundary: utilities
+
+| Module | Responsibility and constraints |
+| --- | --- |
+| `src/utils/index.ts` | Existing export barrel; no added runtime names or wrapper methods |
+| `src/utils/format.ts` | Clamp, capitalization, clock formatting and HTML entity conversion; reusable private lookup maps |
+| `src/utils/property.ts` | Native defineProperty alias, own-property inspection and recursive merge; keys are written as own data properties |
+| `src/utils/time.ts` | Sleep, trailing debounce and leading throttle; infer argument tuple/receiver, preserve scheduling and synchronous return behavior |
+| `src/utils/error.ts` | ArtPlayerError, truthiness guard and internal rejection handling; public media promises are handled elsewhere |
+| `src/utils/file.ts` | Historical extension parsing and transient download anchor lifecycle |
+| `src/utils/subtitle.ts` | Existing SRT/ASS-to-VTT text conversions and VTT Blob creation |
+
+These modules do not import the player, UI components or each other except for the
+barrel. Existing DOM and browser capability utilities remain JS and are re-exported
+unchanged. Emitter and Component are separate migration tasks. Imports from the
+barrel must not silently add runtime fields to `Artplayer.utils`.
+
+## Observable utility behavior
+
+- `def` is the native Object.defineProperty function. Property keys include symbols;
+  descriptors, return identity and own-property behavior remain native.
+- mergeDeep iterates own enumerable string keys. Existing nested objects are recursively
+  merged, a previously unseen value retains its reference, and the historical
+  `previous.concat(...incoming)` behavior flattens incoming nested arrays by one level.
+  It returns a new outer object and does not mutate inputs. `__proto__` now becomes
+  an own data key instead of invoking an inherited setter or replacing the result prototype.
+- Debounce discards earlier pending calls and uses the final arguments/receiver.
+  Throttle runs immediately, ignores calls in the wait window and does not schedule
+  a trailing call. Its wait flag is set after invoking the callback: synchronous
+  reentry and retry after a thrown callback retain historical behavior. Both wrappers
+  return undefined. No new public cancel/flush methods were introduced.
+- silencePromise handles only values with a callable catch and preserves other
+  values. It is for internal event handlers; do not wrap public play/toggle promises
+  to hide their rejections. The property-access assertion is local to that duck-typed
+  boundary, and stack capture is guarded for engines that do not implement it.
+- Subtitle conversion preserves the existing limited formats, whitespace and time
+  normalization; it is not a complete ASS parser. The caller owns and must revoke
+  vttToBlob's returned URL. Download owns its temporary anchor and removes it in
+  finally, including click failure. It does not revoke caller-owned URLs.
+
+## Types and remaining work
+
+Migrated sources compile with strict/noUncheckedIndexedAccess and browser-only
+ambient types. The merge accumulator is a dynamic string-key boundary with one
+documented cast to the pre-existing generic return contract. No file-wide any or
+type-check suppression was added. The main public declarations remain a separate
+compatibility surface; see [types/README.md](./types/README.md).
+
+Existing declaration discrepancies are still tracked for CORE-07: Utils lacks some
+runtime exports, def is declared void, debounce/throttle declare the callback return
+instead of void, and debounce's old optional context argument is ignored at runtime.
+Sleep's declaration also requires a delay while runtime defaults to zero. These were
+not silently tightened during source migration; use the actual source types internally.
+Lifecycle-owned timer cancellation is part of CORE-04/17 and the existing BASE-PERF-01
+finding, not a claim that a standalone debounce can know when its owner is destroyed.
+
+## Verification and maintenance
+
+Run `yarn test:unit` for shared published/workspace utility contracts and controlled
+timers. `test/utils.test.js` also accepts `ARTPLAYER_TEST_CORE` to test an actual
+UMD, legacy or ESM file. `test/types/utils-source.ts` checks source inference, receiver
+types and invalid arguments. Test fixtures supply timers explicitly to isolated
+published UMD contexts; production code is not patched for tests.
+
+Run `yarn typecheck`, `yarn build artplayer`, then `yarn build:i18n` (core build clears
+dist first). `yarn test:package:release` rebuilds and installs a candidate outside the
+workspace. Set `ARTPLAYER_BROWSER_ARTIFACTS` to its mapping and run `yarn test:browser`
+for real playback, chapter integration, downloads and Blob URLs. Preserve generated
+core files in docs/compiled when committing a shippable core change.
+
+For new utility behavior, extend the same old/new contract tests. Clearly separate
+intentional defect corrections from preserved behavior. For timers or Blob URLs,
+also identify the owner and verify cleanup in the consuming module. Remaining
+constructor, playback, UI, Emitter, Component and capability migrations are recorded
+in refactor/tasks.json and should extend this map as they land.

+# CORE-01：核心工具模块 TypeScript 迁移
+
+## 实际源码与边界
+
+time/property/format/file/error/subtitle 与导出 barrel 共七个生产文件迁移到严格 TS。
+沿用现有合理职责划分，无机械增加空转发文件。纯计算不接收播放器实例；DOM 下载和 Blob URL
+创建的资源责任有明确说明，见 [核心架构](../../packages/artplayer/ARCHITECTURE.md)。
+
+核心入口及 DOM/capability/Emitter/Component 仍为 JS，由后续任务迁移。没有宣称核心整体完成。
+Artplayer.utils 的运行时导出与之前工作区完全一致；对发布基线的两个已有扩展
+silencePromise/getSafeAreaInsets 也保留。函数参数个数、native def、属性描述符、调用方数组引用、
+合并时一层 concat 展开、字幕字符串、定时器 this/参数/前沿后沿/重入/抛错行为均有对照测试。
+
+格式化的私有实体映射复用，getExt 改为一次截取 query/hash；保留原字符串结果和 ES2015 能力边界，
+没有据此宣称浏览器性能提升。ArtPlayerError 的栈捕获按实际引擎能力判断；内部 Promise 抑制
+保持与外部 play/toggle Promise 分离。
+
+## 有意修复与类型债务
+
+- UTIL-MERGE-01：Object.keys 遍历到 JSON `__proto__` 时，旧实现改变返回对象的原型。
+  现在用 own data descriptor 写键，保留普通合并语义；嵌套情况、输入未变和原型未替换通过。
+  这是结果对象原型的修正，不声称旧实现已被证明能修改全局 Object.prototype。
+- UTIL-DOWNLOAD-01：下载临时 anchor 在 click 抛错时也由 finally 删除；异常继续传播。
+  三浏览器验证真实下载成功及受控失败清理，调用者提供的 URL 不被擅自 revoke。
+- BASE-TYPE-05：公开 Utils 声明原有缺项、定时器返回值/context、def/sleep 签名差异继续交给
+  CORE-07。本任务内部类型已准确描述返回值/receiver，公开旧消费未静默收紧。该条保持 open。
+
+动态 merge accumulator 和 catch 鸭子类型各有局部边界，未增加全文件忽略、运行依赖或泛化 any。
+
+## 验证
+
+- `yarn ci:check`：75 项 Node/基线测试通过，严格源类型/31 个消费场景通过。
+- 新增 13 项工具测试含发布/当前对照；实际 core UMD、legacy、ESM 各运行 18 项通过。
+- `yarn build artplayer` 和 `yarn build:i18n` 重新生成 core dist 与 docs/compiled。
+  当前核心产物同时包含 ENG-06 已验证的 AMD 修正，之前 tracked dist 尚未重建；没有手改产物。
+- `yarn test:package:release` 实际安装后 23 项运行时、五组类型零诊断。
+- 安装候选 Chromium/Firefox/WebKit 总计 69 项通过，无重试/跳过；包括旧核心/新 chapter、
+  新核心/旧 chapter（工具页面加载）、播放/seek/切源/销毁、真实下载和 VTT Blob 数据。
+  新核心与旧 chapter 的完整插件功能仍由后续组合任务覆盖，不把加载脚本当作完整集成。
+- [执行指纹](../baselines/core-utils-validation.json) 核对最终 runtime 文件与浏览器加载内容、
+  仓库生成产物一致。包内文档增加后重跑打包，运行时 SHA 未变，无需重复播放同一字节。
+
+更新测试入口和包内维护文档；新增风险进入统一台账。下一项按依赖迁移 Emitter 等核心模块。
+没有升级包版本、推送或发布。回退本任务独立提交会同时恢复源码、测试、记录和生成产物。

 # Real browser tests

+`test/utils.test.js` compares the published and current utilities, including exact formatting,
+subtitle text, property/merge behavior, controlled timers and the full utility export surface.
+It accepts the same `ARTPLAYER_TEST_CORE` option for all three artifact formats. The merge
+prototype fix is a candidate assertion alongside a published-only defect observation.
+`test/types/utils-source.ts` checks strict internal source inference without changing the
+still-separate public declaration contract. Browser utility tests exercise actual downloads,
+Blob URL contents and cleanup when a controlled click fails.
+
 See [browser/README.md](browser/README.md) for `yarn test:browser`, browser installation,
 published/current combinations, media fixtures, candidate mapping and failure reports.
 These tests are separate from the fast Node suite and run in the Browser playback smoke CI job.
