Just took the pipe off the top of the cyclone and stuck my finger in it.

Hmm, I wonder if I cleaned that pipe? Not 100% sue, but I think I did. If I did, I don't think that's looking good. Something else to investigate
I believe having trace amounts of oil in the plumbing of the cyclone breather is quite normal. As said, inasmuch as it serves to separate oil from the crankcase gases, oil mist will leave condense in parts and leave signs of oil as you have there.
Just a thought, but have you checked if your valve stem seals are still seated?
On my 200tdi, whiles setting valve lash one time, I found that three of the stem seals had detached from their seats and were floating with the valves they were supposed to be sealing.
At the time, I put down down to overboost conditions that were brought on when the hose leading to the wastegate actuator was leaking.
I assumed the extra boost probably popped them off, because all three were on intake valves.
Suffice to say, after reinstalling them, my oil level stayed on mark between services, so I was quite pleased with that find.
All the best with yours, but honestly, I wouldn't worry too much. We followed you through your rebuild from the beginning, and I wouldn't have done anything different from all that you've done.
Cheers
