I don't think I've see anyone have eligiblity issues over what happens in the summer. I could be wrong, but my guess is the KHSAA would not even have to rule on her. It's as if she never left, since she never actually played a game that counts for another school.
The only potential problem would have been trying to get eligible at a school you enrolled in before you actually moved.

This is correct. The KHSAA does not have any control over players summer activities with the exception of the two week Dead Period, which would affect schools that have summer teams.

However, according to some post on this thread there is some type of proposal that may change that to more KHSAA control next summer, if it passes with enough votes.
