 模型只使用单次请求内有效的临时编号，不接触画像条目的内部 UUID；不合规建议会被跳过，不阻断其他有效更新。
 临时用户别名不会写入最终画像。`profileCompact` 可独立清理重复或低价值条目，且不推进历史水位线。
-旧历史可通过 `profileAnalyze` 或 `profileAnalyzeGroup` 手动分批推进。

+显式传入群号时仍只分析指定群。全量模式仅发送启动和最终汇总，逐群进度与结果写入日志，避免回执刷屏。
 
 下一次正常群聊会自动携带触发者和最近发言者的认识。现有好感度、Bot 代号、标签和主观印象会与证据驱动的
 长期画像按同一个人合并渲染，并明确给出长期画像条目数；私聊也会携带对方的可靠画像摘要和条目数。
