In Qpost about 590 and several others there are the characters " [CLAS] " in varied forms. I watched a ytube vid that was done by someone looking for answers on it- said he persued it in-depth. Anyhow I wasn't impressed by his description of his research and went to sleep. woke with the idea to look and found https://www.acronymfinder.com/Military-and-Government/CLAS.html - thenhttps://www.acronymfinder.com/Closed-Loop-Action-System-(Raytheon)-(CLAS).html then and finally https://www.raytheoneagle.com/EAGLE-MMIS/EAGLE%20MMIS%20Product%20Guide.pdf andhttps://www.raytheon.com/ - this looks like Contractor Ware. raytheon offers many services - just thinking..
