+- `WorkbenchContributionHostTests.chineseActionSearchFindsAndRestoresHiddenTerminal` 使用实际中英资源验证中文标题、中文说明和英文别名，执行后恢复终端入口，切换回英文后不再沿用旧语言；修复前中文查询确认为空。Core 的 `shared/fixtures/search/actions-v1.json` 验证排序、Unicode、插件原文和输入预算。 动作匹配实现位于 `rust/lithe-core/src/action_search/mod.rs`，遵循 Core 根目录仅保留 `lib.rs` 的既有布局规则；模块路径和 `search.actions` 协议不变。
 
 - `WorkbenchContributionHostTests.toolWindowsMenuRestoresHiddenTerminalAtItsSavedDockWithoutToggling` 覆盖隐藏入口恢复、原停靠组、重复 Show 不关闭、模块禁用及旧菜单动作；已安装声明式插件流程补充从同一菜单恢复。`ContextMenuCoverageTests.rightClickOnMenuItemReplacesThePopupWithoutRunningItsPrimaryAction` 用原生右键事件验证菜单交接与执行，不运行主动作；模型回归确认恢复图标时没有模块激活或终端会话。实际产品还需在深浅主题检查左侧“…”、菜单打开/关闭、快捷键与终端已有会话。
