​
total_token_count
integer | null

Sum of prompt_tokens + completion_tokens across every span on the trace, computed at ingest time (TRU-250). Zero when no span reports token usage. Traces ingested before the column existed remain at zero until re-ingested. Queryable via token_count_min / token_count_max on GET /v1/traces.

​
prompt_tokens_total
integer | null

Sum of prompt tokens across every span on the trace, computed at ingest time.

​
completion_tokens_total
integer | null

Sum of completion tokens across every span on the trace, computed at ingest time.

​
tag_map
object

User-defined key→value tag map persisted to the dedicated tags column (TRU-215). Omitted when the trace has no tags. Pre-TRU-215 traces stay without this field until re-ingested.

​
metadata
object
​
span_count
integer
​
control_loop_depth
integer | null

Number of executed retry control_actions rows attached to this trace (TRU-362). Escalations are excluded from the count — once an attempt is auto-converted to escalate, it does not advance the depth. Omitted on the trace list response; populated only on the trace detail response.
