How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

🩺 Stability & Availability | 🔴 Critical | ⚡ Quick win
Remove the duplicate child insertion.
createWidget already calls setParent, which appends the widget to the resolved parent on Line 126. This line appends the same pointer to ctx.mRoot->mChildren again. Root-level widgets are rendered twice, nested widgets appear in two branches, and Widgets::clear() can recursively delete the same pointer twice.
Proposed fix
Widget *widget = createWidget(ctx, parentId, rect, WidgetType::Container);
- ctx.mRoot->mChildren.emplace_back(widget);🤖 Prompt for AI Agents
