Threshold Set Assignment Assigned By

The assignedBy field on a ThresholdSetAssignment establishes accountability for who configured each site's regulatory coverage. Since ThresholdSetAssignments directly control which concentration limits trigger Exceedances and compliance notifications, knowing who made each assignment is important for verifying that changes were authorized. In multi-person compliance teams, the assignedBy record lets administrators confirm that a regulated standard was activated by an appropriately qualified compliance manager rather than an unauthorized user.
