I've previously used just copper crush type for commando. When I had issues with roses staying tight, went to steel sealing washers as recommended by several here to help keep roses tight. Ultimately still had issues and had the ports sleeved, went beck to copper sealing washers.You mentioned copper and steel washers earlier. Are you using the correct crush washers ?
Not sure what you mean here. The rose nut abutts against the flange and pushes it towards the head until it contacts the sealing washer/head. There's still exposed thread on the nut so it hasn't bottomed out in the threads of the sleeve. Verified this by threading the nut without pipe/washer and all threads disappear fully into sleeve. A short "depth" to the pipe flange would just position whole pipe a bit further rearward once nut is fully tightened. Too deep a pipe flange would just place pipe slightly forward when nut goes tight.Are you sure the flanges on your pipe are deep enough.
Just throwing it out there.

Copper crush sealing washers for commando. They have been on bike when I acquired 5 yrs ago, so maybe overly flattened. New set, plus spherical type on order.Not sure what you mean by ‘sealing washers’ ?
My point is that the correct crush washers are thick. Their thickness allows them to absorb / take up a lot of non uniformity, high spots, etc, as they are tightened and ‘crushed’.
If your washers are not like this, you could easily be tightening up on a high point. If that was the case, it would be tight, but still allow movement. So might be your issue?

However, the standard "Seal Washers" aren't all that thick (0.10") and with three 'folds', can't have much internal space left to 'crush'.

A lot thicker, and more crushable, than your average flat copper washer !
Possibly, but I think the original (asbestos filled?) T2166 Norton twin copper sealing washers were the rolled copper sheet type, not solid.
Still available for singles (almost certainly non-asbestos ceramic if filled?).

Tig it .Why new? Fix it ,or have it fixed. Brazing is better than welding.
Had not cleaned it up as much and didn't need to fully pull the rose all the way back off the welded on section, also didn't have my lighting stick there that day as I was only doing washer/re-torquing the nut.So, if you removed the rose to inspect/replace the crush washer, how did you not see the crack?
