- api.ts：call 与 fetchUpload 里逐字相同的响应 envelope 解析 （json().catch(null) + ok/value 判断 + SidebarApiError 构造）收敛为 私有 readEnvelope<T>()，两处调用；判断顺序与错误码回退逻辑不变。 - 取扩展名双实现收敛：extOf 的实现迁至零依赖的 paths.ts（lang.ts 与 service.ts 均可达的基础模块），lang.ts re-export 保持既有导入面 （tests/file-types.spec.ts 从 lang.ts 导入 extOf）；service.ts 删除 模块私有的同体 extOfPath，matchFileViewer 改用 extOf。方向说明： service.ts 不能反向 import lang.ts——lang.ts 携带全部 @codemirror/* 依赖且只经 editor 懒加载 chunk 进入浏览器，core bundle 静态引用它 会把 CodeMirror 拉进核心包（构建产物已验证：client.js / client-registry.js 中 0 处 codemirror，client-editor.js 不变）。

/**

|
* host is the authority for path semantics, so this mirror deliberately
|

* accepts a SUPERSET of absolute forms — anything a Windows host would emit
|
|
* (drive letters, UNC) plus POSIX roots. A form the host would reject
|
|
* (e.g. a backslash UNC path on a POSIX host) passes through here and then
|
