Retrieves all queue items across all jobs and paths, filtered to show work relevant to a specific operator. This endpoint powers the operator kiosk view where an individual operator sees only their assigned work.
Unlike the _all queue endpoint, this endpoint only includes steps that have at least one in-progress serial — first steps with zero serials are not included. The response shape is identical to the _all endpoint but with the operatorId set to the queried user ID.
Note that this endpoint currently returns all queue items regardless of assignment, not just those assigned to the specified user. The userId parameter is recorded in the response's operatorId field for client-side filtering. The frontend uses this to filter the displayed items by the selected operator.
The endpoint does not validate that the userId corresponds to an existing user. Any string is accepted and echoed back in the operatorId field.
Currently, the server returns all queue items regardless of assignment. Client-side filtering by assignedTo is expected. This may change in a future version to filter server-side.
Steps with zero serials are excluded (unlike the _all endpoint which includes first steps with zero serials).
Items are deduplicated by the composite key jobId|pathId|stepOrder.
This endpoint does not include previousStepId/previousStepName fields.
