Get a session
GET /v1/sessions/{sessionId}
The caller’s own session, or one someone else shares with them, with its owner. A shared session’s history, files and stream read the same way; only its owner changes it, sends to it or stops it (404 for others).

The Book the session was started in: its first input’s bookContext. Fixed once set; absent when that input had none.
Present when the session is someone else’s, shared with the caller: the caller can read and continue it, never change it.
object
The owner’s display name, as Bkper verified it.
Present when the session was copied from another person’s shared session, to continue it as the caller’s own. The original is unchanged; the copy carries its history, not its files or instructions. Such a session has no parent.
object
Where the copy ends: through entryId, or before it. Open: at | before.
object
The original’s owner, as Bkper verified them when copied.
