Maybe the shift drum is off slightly. Allowing one of the dogs to tic against the gear next to it when leaned?....why this occurs on a right lean and disappears on a left?

You using a stock clutch worm actuator or one with more throw? More throw would push the pressure plate further out........And, why it has been rubbing on the inside of the case off and on.
pics to follow.Maybe the shift drum is off slightly. Allowing one of the dogs to tic against the gear next to it when leaned?
Measure the radius of those scrub marks in the cover, from the protruding nub, it should be the center. Compare that radius with the pressure plate, see if it aligns with the springs screws, or something else.
Where you're showing the 0.020" feeler gauge, check for scrape marks there on the case, and on the backside of the basket gear. Proper setup there is to have 100% mesh of the basket gear with the crank's primary gear, no overhanging of gear teeth.
See if the mainshaft's double-row bearing, behind the clutch, looks damaged, or has any lateral play. Since its inner race is clamped between the mainshaft's 1st gear and the clutch hub, reassemble the clutch minus the basket and plates. Just the washers, spacer, and hub. Just snug the hubnut. Then, by hand, try to force the hub in/out of the engine. Should have zero movement, and no sounds.

The inner hub should be proud of the splines. If it's not, the nut and washer will just tighten against the shaft splines and the hub will be looseMaybe that's the way it should be but I just think they should be flush? Dunno.
Here's a pic if I remove the 2mm washer that is supposed to be there. Now it's flush.
The play in the video looks like it's the outer basket that's moving and not the inner hub.... correct?
Excellent point Bob. I didn't think of that.....Is play natural due to the fact they are not tightly joined together?
I'm not convinced yet that what we're sein' is excessive. We could be just chasin' our collective tails here....Could your gear/ basket assembly have developed some excess play?
... back in 1990 when the mechanic who replaced the shift shaft didn't have things seated properly somehow, and the clutch wasn't disengaging, a neighbour and I pulled the right case off, saw those marks where the pressure plate had rubbing on the case and did 'something' that fixed it. That was 28 years ago and I can't for the life of me remember what. From then until 2008, when I took it off the road I never had any clutch problems...
CHAPTER 2.
And now for the long awaited video.
I can move the hub in and out along the mainshaft,
Was able to capture a couple of videos of me rocking the hub
I think you can see how the hub is moving as well.

Well, it definitely moves and makes a noise when doing so...
