Oh ... I tried something similar, and saw
prevdepth but no prevgraf -- let me try
your example and see how it differs ...
Yes, you're quite right : \showlists after
a non-empty paragraph and a \par does indeed
show the current value of \prevgraf. Unfortunately
it doesn't help me to find the value at a \vadjust !
