google.internal.lower_journal

ai.Journal -> generateContent `contents`. Only promptable events lower; ai.RunStarted, ai.ToolRequested, ai.Usage, and ai.FinalProduced are journal-only. Consecutive tool results merge into ONE user content of functionResponse parts, matching how Gemini expects results for a multi-call turn. Gemini correlates results by tool NAME, not id (`ai.wire.tool_name`).
