## Runtime types
|
||||
|
||||
`src/types.ts` defines options, result, rectangle/cue data, owned events, cleanup and
|
||||
preview inputs. Request cancellation is typed as a void branch; actual registration is
|
||||
Promise<Result>. The lifetime accepts only destroy/setBar and uses the core event tuples.
|
||||
The preview receives only its required DOM/style/duration inputs.
|

|
||||
Assertions are limited to the real Artplayer constructor boundary, validated regex groups
|
||||
and loop indexes, the completed four-key rectangle, and native responses after the closed
|
||||
check. The latter is valid because native fetch returns Response and cancellation only
|
||||
resolves void after closing; malformed custom responses still throw at runtime. Numeric
|
||||
rectangle strings are explicitly converted for arithmetic while the zero style write stays
|
||||
numeric. No any, unchecked JS or skipLibCheck exception is introduced.
|
||||
|
||||
The package tsconfig also checks test/types/vtt-thumbnail-runtime.ts. It tests the async
|
||||
result, required options, CSS/URL types, event tuples, cancellation, readonly state and raw
|
||||
rectangle strings, including expected errors. It separately proves the old public result
|
||||
is synchronous in declarations; those declarations are not silently corrected in this
|
||||
runtime checkpoint. New/old declaration consumers and export aliases remain task 04.
|
||||
|
||||
## Compatibility and intentional fixes
|
||||
|
||||
Option/style remain live at their historical read points. The return stays a Promise;

# PKG-VTT-THUMB-04 严格运行时类型检查点
|
||||
|
||||
六个 JS 实现迁为 TS，并增加 types.ts，明确 Option/Result、字符串矩形和 Thumbnail、
|
||||
资源生命周期、事件元组与最小预览输入。分包 allowJs=false，继承 strict、
|
||||
noUncheckedIndexedAccess、skipLibCheck=false、types=[]，不引入 any 或忽略检查。
|
||||
运行时注册准确返回 Promise<Result>，取消分支为 void；parser 输入用 unknown 并先验证。
|
||||
|
||||
新增由分包 tsconfig 检查的正反例，覆盖 URL/CSS、必传参数、异步结果、关闭状态、
|
||||
事件元组和矩形字段。非空/类型断言仅用于已校验正则/数组边界、四键对象构造、
|
||||
真实 Artplayer constructor 和关闭检查后的原生 Response；包内架构说明具体不变量。
|
||||
数值计算显式 Number 转换，保留正常坐标/进度样式及零值写入。
|
||||
|
||||
公开声明、package exports、版本、依赖保持原样。类型用例明确复现旧声明返回同步
|
||||
对象与实际 Promise 的冲突，没有靠给 Promise 增加 name 属性或类型断言伪造同步结果。
|
||||
04 继续 doing，下一步验证旧编译器/消费形式、异步类型视图、CJS default 兼容、
|
||||
模块声明和编辑器；不能将严格内部类型通过等同于公开声明已完成。
|
||||
|
||||
本次沿用 246 项本包契约/错误/候选测试，并验证正式构建和真实浏览器。
|
||||
准确入口、类型和 CI 结果见 [验证记录](../baselines/vtt-thumbnail-runtime-types.json)。
|
||||
正常构建生成 dist 与 docs 副本；无新依赖。内部源码路径从 .js 迁至 .ts，历史
|
||||
源码深导入仍归 06 分发审查，当前不能声称所有深路径已验收。
|
||||
独立本地检查点提交；回退可恢复前次 JS 实现，不影响历史冻结测试。不推送或发布。
