 * NOT THE DIAGNOSTIC REPORT READ THE CHART USES. A bench technician holds the Staff group, and

 * not open it again. This route hands back the attachments on a single order instead, to somebody the
 * order's own permission already lets work it.
 *
 * ASKED FOR WHEN SOMEBODY ASKS. A queue is not a record: reading a report per row would cost a request
 * per row, and most rows are never opened.
