 ### 渐进式历史画像（实验）
 - 日常使用无需画像命令：群聊缓存会话闭合后，一次模型调用会静默归纳其中所有有实质发言的参与者
- `/jgpt profileAnalyze <userId> [batches]` - 诊断或验收时手动推进指定用户画像，默认1批、最多50批
+- `/jgpt profileAnalyze <userId> [batches]` - 手动推进指定用户画像，默认1批
+- `/jgpt profileAnalyzeGroup <groupId> [batches]` - 按群历史批量推进参与者画像，默认1批
 - `/jgpt profileShow <userId>` - 诊断或验收时查看已经提交的完整画像和覆盖时间
+- `/jgpt profileCompact <userId>` - 独立反思并压缩指定用户的重复、过细或低价值画像条目

+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。
