tumbling rocks? grinding? groaning? what is it doing?

grindy rocky noise but doesn't sound like the typical coupler... sounds like a bearing is going out or possibly a rough point on the rotors rubbing the case. During the rev up it only gets faster so its bad but you really need a mechanics stethoscope to determine if its from the snout (needle bearings or coupler) or from the case itself (rotor bearings, rotors rubbing)
could be fixable without having to order a whole new supercharger

it sounds like a 2 stroke dirt bike engine if that helps describe the noise
to be completely honest i was planning on porting the gen 3 but I can always get a used gen 5 blower from zzp for 500 bucks + TB adapter plate

When the car is at idle and the bypass valve is held shut, the noise gets quiet but when open in vacuum the noise comes back???

remove the s/c belt and turn the pulley back and forth like snap it, and feel for play in the pulley, if so you at least know you need a coupler.

when the bypass valve is held shut there is play in pulley but after letting go it feels more firm (not sure if thats the word im looking for)
