 - The community plugin's install path remains valid but redundant; its original routes and browser choice key are separate from `open-in-app`, so installations using the first-party feature should remove the community plugin to avoid duplicate header controls.
 - Resolution and icons run lazily, once per host process, so an application installed while dsh runs appears only after restart — accepted; the uninstall direction self-heals through the `ENOENT` single-entry refresh.
 - The catalog is compile-time fixed; extending it means editing `OPEN_IN_APP_CATALOG` and both locale dictionaries together (README Known Limitations). Platform coverage is uneven — several Git GUIs and terminals are macOS-only entries, Windows icons are limited to the 32px stock .NET extraction, Linux follows hicolor rather than the active theme, and CLI-only entries without a desktop record keep the generic icon.
-- Resolver, icon, route, controller, and component tests cover platform discovery, launch outcomes, the availability cache, and HMR disposal. The [SSH Web snapshot](../../../../snapshots/web/open-in-app-ssh/snapshot.yml) renders the shared recorded conversation with both Open In rows enabled and a remembered app choice; inherited SSH markers make the empty catalog deterministic across platforms. Ordinary Web snapshots keep host-dependent application discovery disabled.

 - 社区插件的安装路径仍然有效但已冗余；其原始路由与浏览器选择键独立于 `open-in-app`，因此使用第一方功能的安装应移除社区插件，避免出现重复的头部控件。
 - 解析与图标每主机进程惰性执行一次，dsh 运行期间安装的应用要重启后才出现——接受；卸载方向经 `ENOENT` 单条目刷新自愈。
 - 目录在编译期固定；扩展它意味着同时编辑 `OPEN_IN_APP_CATALOG` 与两份 locale 词典（README 已知限制）。平台覆盖不均——若干 Git GUI 与终端仅有 macOS 条目；Windows 图标受限于 .NET 标准接口的 32px 提取，Linux 跟随 hicolor 而非当前主题，没有 desktop 记录的纯 CLI 条目则保留通用图标。
