Name	Type	Default
`id`	`string` Unique identifier for the session
`title`	`string` Title of the session
`createdAt`	`Date` Date and time when the session was created
`updatedAt`	`Date` Date and time when the session was last updated
`conversations`	`Conversation[]` Array of conversations within this session

`Conversation`
