The comp cover is dimpled on the edges by design - holds the guts in. I am thinking you had a loose comp nut. The broken washer (no scale shown) could be the large washer that was used in some instances under the head of the comp nut to ensure clamp load. You need to disassemble it and all will become clear.

That compensator cover shouldn't look like this shut it? It looks almost deformed or welded on the front face and then dented in multiple places around the rim
Comp nut is loose.. The outer cover that holds the springs should not turn but be clamped to the end of the crank It wouldn't surprise me if the washer was one to help seat the comp. May not be a whole lot of damage.

so you think the two chunks of metal I found were part of a washer that was being used as a shim between the compensator nut and cover? Do you think that cover should be replaced? I don't know if you can tell from the video or the picture but it has a weird mark on it almost like it has seen a stick welder even though that makes no sense

Need to take it a part. You will also need to check the splines on the alternator rotor and crankshaft.
Add:
The weld is normal. It's a sheetmetal piece welded to a machined piece.
The comp nut could be loose or the tensioner shoe cracked and fell off. I'm not a fan of the L shaped tensioner but did manage to put 80000 miles on one.
There's a tsb on 2005s re the comp nut. It needs to be shimmed 30 thou or it'll come loose.

Two of the most knowledgeable forum members are giving the OP the right information; all he need do is listen and follow. The early compensators are actually fairly robust pieces of hardware. The washer Ed is referring to is shown in the attached diagram as a shimand is a very common remedy used to achieve the required clamping pressure.
I'll chime in only because I was in my 08 UC a few weeks ago.
Get it apart as mentioned.
The older compensators just gave it up to soon in a lot of cases. Not all but to many anyhow.
There are several threads here on forum about them.
I think the bottom line is if the splines that the rotor mounts on to are good___ fairly easy repair. I didn't say cheap tho.
Those splines just happen to be the left side of your crankshaft.
