## Что это ## Резюме (RU) T539: полировка встроенного нативного интерфейса Rox Design *Полный перевод тела — в работе. Английский оригинал ниже.* --- # Original (EN) ### Objective Make the embedded Rox Design/Open Design surface feel like a native ROX.ONE screen, not a nested foreign app. This matters because the current visual state is confusing: ROX navigation, Rox Design host chrome, and Open Design internal chrome compete on the same screen. ### Source Links * GitHub issue: [https://github.com/agisota/rox.one/issues/271]() * GitHub PR: none yet * GitHub branch: codex/rox-design-native-skin-checkpoint-20260519 * GitHub Project item: [https://github.com/users/agisota/projects/9]() * DeepWiki/repo context: [https://deepwiki.com/agisota/rox.one]() * Local branch / cwd: codex/rox-design-native-skin-checkpoint-20260519 / /Users/marklindgreen/Projects/rox-one-terminal-rox-design * Parent roadmap item: PZD-10 [PZD-10](https://linear.app/id-2/issue/PZD-10/feature-claude-artifacts-style-agent-result-panel-github-271) ### Current State * Current active task: polish Rox Design native embedding after user visual feedback: "Пока что кривенько встроили". * Last completed meaningful action: current branch/worktree/diff were preserved; no reset/checkout/destructive command was run after the Linear-first directive. * Files currently touched locally: apps/electron/src/main/**tests**/rox-design-view-manager.test.ts; apps/electron/src/main/rox-design-embed-skin.ts; apps/electron/src/renderer/components/app-shell/AppShell.tsx; apps/electron/src/renderer/components/app-shell/MainContentPanel.tsx; apps/electron/src/renderer/components/app-shell/TopBar.tsx; apps/electron/src/renderer/pages/rox-design/RoxDesignPage.rtl.test.tsx; apps/electron/src/renderer/pages/rox-design/RoxDesignPage.tsx; scripts/electron-ui-smoke-packaged-mac.ts; apps/electron/src/renderer/components/app-shell/design-surface-policy.ts; apps/electron/src/renderer/components/app-shell/**tests**/design-surface-policy.test.ts; docs/tickets/T539-rox-design-native-embed-polish.md; docs/worklog/T539-rox-design-native-embed-polish.md. * Completed tests before this intake: targeted main helper test, design shell policy test, and RoxDesignPage RTL test passed in the previous implementation pass. * Observed behavior: initial packaged smoke captured blank ROX host screensho... ## Статус Это задача из текущего backlog'а ROX.ONE (Linear).
