Thanks. No evidence of water damage at the interior founds visually, by IR or with a meter - there a number of problems with that stucco and the roof above it, and I was prepared to find some.
One of my concerns is that based on detailing elsewhere, this appears to manufactured stone, and if so may be subject to problems from even "small" areas of moisture intrusion:

so I'm aways a little skittish when I see it, and in this case none of the installation guides I can find discuss detailing at that sort of irregular junction.
