Well, it survived a set of doubles and one set of singles tonight. A friend who suffered a similar incident and examined it agreed it's probably just superficial. Same criteria as many have mentioned here: sound and feel are good signs. Next test will be re-restringing. In any case, definitely buying another one just in case!
