Run stuck queued? queue.state waiting vs runtime_unavailable
queue.state waiting is normal pickup; runtime_unavailable means nothing claimed the run. Position is always null. Back off, then contact support.

Read queue.state on the status payload before you panic. Sume reports waiting while the run is inside the normal pickup window, and runtime_unavailable when it waited longer than that and nothing claimed it.
What each state asks of you
| queue.state | Meaning | Do |
|---|---|---|
| waiting | Normal pickup window | Keep polling status_url with backoff |
| runtime_unavailable | Waited past the window, unclaimed | Back off for retry_after_seconds |
| (either) | queue.position is always null | Do not show a place-in-line |
Poll the small payload
status_url returns status, next_action, cancelable, expires_at, queue and the URLs, without output or artifacts. Use expires_at as your ceiling: the deadline is 90 minutes after created_at, or earlier when the run is older than 25 minutes and was silent for 10.
curl -sS "$STATUS_URL" -H "Authorization: Bearer $SUME_API_KEY" \
| jq '.data | {status, expires_at, queue}'If it lasts
If runtime_unavailable lasts more than a few minutes, send a support ticket with the request_id. In a bulk queue the child still occupies a slot, so one stuck run slows the rest of the window; cancel it with POST /v1/format-runs/{run_id}/cancel if you no longer want it.
