from line 202
208202 A transcript marker generated by the endpoint rather than sent by
209203 either party during the session. Marker messages indicate that the
210204 prompt history diverged from what was captured, that the request's
211 `system` field was present but is not shown, or that
212 prompt-carried history was suppressed because the session spans the
213 child organization's retention boundary and those turns cannot be
214 placed against it (the marker's text names the cause). Markers that
215 report a mismatch with captured history can result from normal request
216 or client processing, not only client modification.
205 `system` field was present but is not shown, or that earlier turns
206 that a request re-sent as history were withheld because they cannot
207 be dated against the child organization's data-retention period
208 (only for organizations with a finite retention period; the request's
209 new user input after its last assistant turn is not affected). The
210 marker's text names the cause. Markers that report a mismatch with
211 captured history can result from normal request or client processing,
212 not only client modification.
