I'm testing the tracers today. i'm really hoping that its just stained and not the copper that eroded away. Will get back once I get the results.
If / when it corrodes down through the holes / vias you're beat for connecting to intermediate layers.There's also a lot of corrosion around the pins of U55. I would remove and replace that chip; until you do that, there's no way to know the damage underneath it. A previous photo showed it to be a 74ACT14 hex schmitt inverter.
One big problem is that if you don't get all the corrosion off, it will continue to eat away the traces. I would probably strip off the solder mask, clean everything very well, fix damaged traces, and hope that you don't have corrosion in vias. Once fixed, you can use clear nail polish to replace the solder mask.

Calling @dbaxterI am definitely gonna give it a shot. It was working before we shut down before the pandemic, so I'm gonna keep my fingers crossed. Also with the new guidelines, we are not expecting to need the stage for any purposes this year, so i've got some leeway as far as that goes. But I would love to have a solution so I can present to our CFO and try and get a budget.
