Do "Bodies Found" Count Against Ghosting?
Solution 1:
It doesn't. Here is proof from my recent stealthy, super-lethal playthrough of 'House of Pleasure' mission stats (With no Shadow Kill. Notice that there are 12 bodies found, but 'Ghost' is checked):
Basically, as long as no red 'marker' appears on an NPC or a wolfhound (dog), it won't count as detected. Three white 'markers' won't count as detected. The red marker appears only if an NPC or wolfhound has detected you, not a body you killed or made unconscious.
Also, here are some reports from other posts:
Bodies found does not void the achievements Ghost, Clean hands or Shadow. Completed all three achievements yesterday and I have had missions where bodies were found.

Solution 2:
No, it does not. I was awarded both Shadow/Ghost on my play-through and I ended up with several bodies discovered in the mission statistics for quite a few missions.
