I’m trying to diagnose the cause of these loose cogs? The lockring is tight, the cassette does not move as a whole along its axis, this direction is well fixed. It’s just the cogs individually that are loose… is it the body?

Pull them off and see
Did you recently take the cassette off? Did you put the spacers back on?
You will have to see if the cogs are digging into the freehub body.
Check if the retaining ring is tightened to 50 Nm as labeled.
Your lockring isn’t screwed on. If it is screwed tight, you are missing a spacer, either between cogs, or at the back against the hub. Or you are missing an entire cog.
Pull cassette. Inspect freehub. I can’t be sure from the video, but it does look loose, not tightened or missing spacers.
Shimano hub?
Campag is a bit of a rare beast. The freehub splines are tall so you don’t typically see the kind of biting/wear that you see on Shimano freehubs.
You shouldn’t have to run a spacer behind the cluster. That’s a Shimano thing. But IIRC Campag spacers between sprockets are not all the same size and order matters. Be careful when disassembling and reassembling.
Only other thing I can suggest is make sure the lock ring is not cross-threaded. If it is, it will feel tight but not actually bottom out. Inspect the freehub body threads!
it shouldn’t take more than 5 mins to fix it.
If it’s installed on a hub that takes more than 9 gears you’ll need spacers
You need to tighten the lockring very tight. Mine kept coming loose until a mechanic put a wrench on it and stood on the wrench. Problem free now.
Bet that rattles over rough ground!
