Hypothesis testing Tarkov : Quest help

I managed to decipher the signal. It's old and very weak, and apparently the bunker was blocking it completely until you opened the doors. For some reason, the message keeps looping around, but that doesn't mean anything in itself: the equipment on site could have been damaged for some time. Besides, we still don't know what the TerraGroup team was doing down there. The message states that the facility still contains equipment and data of the highest priority in the event of an evacuation. It also mentions reports of experiments carried out on the site. We couldn't have asked for a better time to discover something so precious! More and more people are hearing about these basements every day, which means it won't be long before merchants and other operators are exploring the area we've brought to light. Maybe even the Lightkeeper will be interested... I need those documents mentioned in the message. Bring me everything you can find, and as quickly as possible.
