 Eino 默认续接摘要使用 `user` 消息角色传输，但同时带 `_eino_summarization_content_type=summary` 的来源标记；保留的技能上下文使用 `skills` 标记。原始用户输入账本按该元数据排除内部摘要和技能消息，不能仅凭 `role=user` 将生成内容归入用户原文。摘要中的模拟用户账本也不作为原始输入来源导入，避免多轮压缩把模型自己写的目标或操作提升为用户指令。快照和摘要模型的文本记录同时标出内部消息的系统生成来源，明确其不是用户输入或新的授权。

 压缩摘要仍保留在模型工作上下文中，不因来源区分而丢弃进展；主/子代理本轮输入仍来自原始请求及原始聊天记录。不会用 `<summary>` 等文本关键词过滤真正的用户输入。回归测试调用实际 `DefaultFinalize`、连续执行三轮压缩并经过 classic/native 转换，核对原始授权目标与禁止测试本机的约束保留、生成目标与模拟指令不进入用户账本、摘要进展不丢失，以及用户引用摘要文本时仍被视为真正用户输入。
