So, reskinned the back tire, put it back on the axle, adjusted the chain tensioners, and torqued all to spec. Less than 200 miles later, dismount to find the left side cap is unseated, the related tensioner bolt is badly bent, and the cap has been chewed up by the chain.
Aside from torquing to spec, should I have put thread lock on the chain tensioner or axle? The axle was still plenty tight, though it had migrated rearward on the left side. What am I missing?

The chain adjusters do not secure the axle in position. That is done by the axle bolts/nuts. When they are tight to spec, the axle can't move on the swingarm.
Sounds like the axle wasn't torqued to the 65 ft-lbs. Did you use a wrench on both sides of the axle? Any corrosion preventing proper torquing?
If the axle migrated rear-wards only on one side, it would get tighter.
You can hammer on a block of soft wood held against the axle to get the migrated side back in position. If my explanation is correct, you would feel the axle become loose.
