目标

createdFrom 记录会话来源入口，isDeleted 替代硬删除。

Schema

createdFrom String @default(global_ai_entry)
isDeleted Boolean @default(false)

原因

createdFrom 影响审计和入口分析。isDeleted 是主流程字段（列表过滤必查）。

完成情况

交付物

ChatSession 新增字段 (prisma/schema.prisma):

createdFrom  String   @default("legacy_migration") @db.VarChar(32)
isDeleted   Boolean  @default(false)

Service 层:

createSession 接受 createdFrom 参数，写入会话创建来源
deleteSession 改为软删除：UPDATE ChatSession SET isDeleted = true WHERE id = ?
- 旧行为：硬删除 DELETE FROM ChatSession WHERE id = ?（会删除消息和引用）
- 新行为：仅标记 isDeleted，保留消息数据

Controller 层:

POST /sessions 接受 createdFrom 字段
DELETE /sessions/:id 返回 { success: true, message: "会话已删除" }

createdFrom 枚举值

值	入口
knowledge_base_detail	知识库详情
material_detail	资料详情
material_reader	资料阅读页
knowledge_item_detail	知识点详情
folder_detail	分类页
global_ai_entry	全局 AI 入口
