 ## Known Limitations and Deferred Work
 
 - **One-shot rendering by design** — the UI waits for the boot settle; a single entry failure keeps the loading page with a loud per-entry report, no partial availability (progressive rendering returns with its own project).
-- **Narrow-window acceptance is deferred** — the concession chain is implemented in ui-layout but the shell-level narrow-viewport walkthrough is a P-II acceptance item.

 ## 已知限制与暂缓事项
 
 - **有意采用一次性渲染**：UI 等待启动 settle；只要一个配置项失败，加载页面就会保留并逐项显示醒目的报告，不提供部分可用性（渐进式渲染将作为独立项目恢复）。
-- **窄窗口验收暂缓**：ui-layout 已实现让步链，但外壳级窄视口演练是 P-II 验收项。
+- **窄窗口外壳行为缺少组装后演练**：ui-layout 已实现让步链，但该包没有外壳级窄 viewport 验收用例。
