WoW! What a great picture of weave exposure. Would suggest that you submit
this to the 600 and 610 groups for inclusion in those documents.
I was going to suggest that you can run a water soluble pen over suspected
areas and if the glass is exposed the weave will wick up the ink and when you
wipe it off with a tissue the result will be little colored spots. If it is
merely texture there will be no spots.
Did you notice this conditon prior to assembly?
