Download Session

Download the complete session history.

The complete, ordered history of the session (agent output, tool calls, thinking, lifecycle events, environment output, message events) as an ordered manifest of presigned segment URLs.

Segments are gzip members: download in order and concatenate for one file. The JSON API never carries the bytes (same two-step as files). /records is the paged live view of the same data.
