对应 P-016 game-reviewer 审查建议（非阻塞关注项）两项： 1. [生命周期] ExecuteHideNarrative 删除 Hide() 后立即 CachedNarrativeWidget=nullptr 的那行，与 Pickup 路径对称；让 RemoveNarrativeWidget 能检测到残留 Widget 并 RemoveFromParent，修复每次交互循环视口残留实例累积。 2. [一致性] NarrativeTextWidget/PickupNotificationWidget 的 Hide() 淡出时长改为从 FadeOutAnim->GetEndTime() 读取（无动画回退 0.2f），消除与动画时长耦合的硬编码；lambda 捕获由 [this] 改为 [WeakThis](TWeakObjectPtr) 避免悬空。 补充：两个 cpp 添加 #include Animation/WidgetAnimation.h（GetEndTime 需要 UWidgetAnimation 完整类型，原仅有前向声明）。UE5.7 编译验证 Result:Succeeded，零 error/warning。 Co-Authored-By: Claude Opus 5.8 <noreply@anthropic.com>
