The members center on Gemini tool/function calls and the thought_signature field: one issue reports an HTTP 400 INVALID_ARGUMENT about a missing signature in functionCall parts, and three pull requests propose changes to how signatures are gated, replayed with a sentinel, or injected. Whether these changes address the reported error is not established by the titles.
