One bug report and two pull requests concern Gemini/Vertex thought summaries showing up in user-visible content when display.show_reasoning is false. The report ties this to reasoning effort and visibility being coupled via include_thoughts, and the PRs propose decoupling them and routing thought deltas to the reasoning stream.
