In relation to your question, ( how to add observations into ones report.) about ghosting.
1: I would introduce all my finding about the furnace, chimney, smokers in the home.
2: add how the air in the home is circulated in streams and column's related to the heat and drafts in that room and home. The same as in atmospheric conditions on the earth that move the clouds rain, hail, etc..
3: how they ( the columns of air ) carry that smoke or soot to the walls surface and the particulates are trapped in certian locations that stick out.
Corners of the room, mirrors or paintings, sometimes any indentation ( concave ) like wall board joints, to convex joints on the wall , like framing seams from the wood framing behind the walls that force a bump on the wall.
Just an idea.

Stop burning the candles and paint.

I thought ghosting was usually caused by indoor vapor on cool spots (heat loss areas) that dust and dirt molecules adhere??

There are several reasons why it could happen. This was wood furs, on exterior walls. The evidence suggests that the owner was burning lots of candles. This would cause the soot that would attach.

Have you read the supplied articles in both posts? "Looks like" is not a very definite assertion when dealing with a phenomenon whose causes are known!
