1973 Front Caliper leak after full rebuild that I can't understand. Could it be a right fork seal leak going down onto the right side of rotor?

I fully rebuilt the caliper with stainless pistons and new seals and a week or two after, the right side of rotor was wet and dirty.
After cleaning after each ride, I pulled the caliber outer piston thinking I would find I had somehow twisted it or nicked it on install.
But it looks perfect.
But I can't see any fork fluid dripping down.

Has anyone had right hand side fork seal failure which dripped onto right side of rotor??

Thanks

I had drip from my master cylinder ( torn boot ) that showed up on the rotor.
 
Discerning the difference between brake fluid and fork oil should be obvious.
Dirty, fluid covered rotor indicates pads not engaging.
Take down the caliper and find the problem.
