58 Transcript turns for this page, ordered by `created_at` in the direction selected by the `order` parameter (ascending by default). Turns sharing a `created_at` (all messages of one inference call carry the call's timestamp) are returned in transcript order.
58 Transcript turns for this page, in call order: oldest call first by default, newest call first with `order=desc`. The messages of one call carry the call's timestamp and follow each other in transcript order; a page boundary can fall between them.

150 The model that served this assistant turn, as reported in the `model` field of the underlying Messages API response. Null on user messages and on any assistant message whose `provenance` is set: client-asserted history and synthetic markers were not produced by a model during this session, and for unavailable content the serving model is not known.

149153
150154 Where this turn's content came from, discriminated on `type`. Null (the common case) means verified content: on an assistant message, content Claude produced during this session; on a user message, content the user sent. `content_unavailable`: the turn's content cannot be returned and `content` is empty; `reason` says why. `client_asserted`: assistant content the client supplied as conversation history; `content` shows what the model received but its authorship is not verified; never on user-role messages. `synthetic_marker`: a transcript marker the endpoint generated rather than content either party sent during the session. Both `client_asserted` and `synthetic_marker` can result from normal request or client processing, not only client modification. Callers should tolerate unrecognized `type` values.

158 Why this turn's content cannot be returned, e.g. `not_captured` (the content was not captured for compliance retrieval), `cmek_key_revoked` (the content is encrypted under the organization's customer-managed key and that key is unavailable), `retention_elapsed` (the content lies past the organization's retention boundary; on the placeholder standing in for every pre-boundary turn), or `oversize` (the message exceeds the server's per-message size bound even after per-block truncation). Callers should tolerate unrecognized values. `not_captured` is not proof that no record was stored: content withheld by the storage layer's fail-closed access policies carries the same reason and is deliberately indistinguishable from content that was never captured.
162 Why this turn's content cannot be returned, e.g. `not_captured` (the content was not captured for compliance retrieval), `client_aborted` (the client closed the connection or cancelled the request before the response completed, so the response was not captured for this turn; any partial output already streamed to the client is not included; assistant-role turns only), `cmek_key_revoked` (the content is encrypted under the organization's customer-managed key and that key is unavailable), `retention_elapsed` (the content lies past the organization's retention boundary; on the placeholder standing in for every pre-boundary turn), or `oversize` (the message exceeds the server's per-message size bound even after per-block truncation). Callers should tolerate unrecognized values. `not_captured` is not proof that no record was stored: content withheld by the storage layer's fail-closed access policies carries the same reason and is deliberately indistinguishable from content that was never captured.

210214 The local session the messages belong to. `user.email_address` is always null on this endpoint; the messages endpoint does not resolve email addresses.

236 - `updated_at: string`
237
238 Timestamp of the session's last retained inference call (RFC 3339, UTC). Always at or after `created_at`. When a session's activity spans the child organization's retention boundary, calls older than the boundary are no longer reflected — but because retention removes only the oldest calls, this value (unlike `created_at`) is unaffected until the entire session has aged out. On the list endpoint this value is a lower bound: for a session still active at a page or `created_at.lt` window boundary it can momentarily lag the session's true last activity. Retrieving the session, or its messages, always reflects the exact latest retained call.
239
232240 - `user: object { id, email_address }`
233241
234242 The authenticated user at the time of the session. Always set; `user.id` is always populated. `user.email_address` is null when the user's account has been deleted or the user is no longer a member of an organization the key may read.
